An electronic bidet is a seat attached to an existing toilet or a part of the toilet itself, with a nozzle to squirt a jet of warm water for cleaning the anus and female genitals, electrically powered and with electronic controls. It replaces the conventional bidet, a separate plumbing fixture not attached to a toilet. Some bidets of this type have one adjustable nozzle on the side rim for anus and genital areas, or two nozzles on the back rim, a shorter "family nozzle" for washing the area around the anus, and a longer "bidet nozzle" for women to wash their vulva. [1]
The essential feature is the nozzle that comes out from underneath the toilet seat and squirts water. It typically has two settings: rear cleaning to wash the anus, and feminine cleaning to wash the vulva, which can be particularly useful during menstruation.
Functionality of a bidet which is not a stand-alone fixture:
In the early 1960s, the father of Arnold Cohen of Brooklyn, New York, US had a medical condition that caused pain in the rectal area. Arnold designed a toilet seat bidet system, which featured a nozzle that sprayed warm water and blew hot air. In 1964, Arnold patented his design, founded the American Bidet Company, and started marketing the innovative bidet product, dubbed "American Sitzbath", by using large ads and attending trade shows. It was intended for use at hospitals by patients who had difficulty using toilet paper or reaching around to wipe themselves. Arnold installed thousands of these seats in the suburbs of New York, and the company had offices across the country. Due to cultural barriers, advertising was almost impossible; few wanted to run the ads that the company produced. [5]
Following the failure of the product in North America, Cohen licensed his invention and patent to the TOTO company in Japan. In 1967, TOTO imported Arnold's bidet system, now rebranded as 'Wash Air Seat' in Japan. The bidet system failed in Japan as well, because it was too expensive and the bidet function was too foreign for Japanese consumers. [6]
In 1980, TOTO introduced the Washlet G, which debuted with three functions: rear cleansing, dryer, and a heated seat. [7] In 1982, the first Washlet television commercial aired, featuring the singer Jun Togawa telling viewers that 'even though it's a bottom, it wants to be washed too'. In another ad, she was shown standing on a fake buttock reading a letter supposedly from her bottom, which writes that 'even bottoms have feelings'. [8]
The Wash Air Seat and the early Washlet operated mechanically, and it took several minutes for the spray to start and for the water to heat. These problems were solved by implementing electronic operation. The Washlet's nozzle was made to extend and retract at an angle of 43 degrees, which prevented any used cleansing water from falling back onto the nozzle ("backwash").
Two TOTO engineers, Mr. Kawakami and Mr. Ito calculated the average location of the human anus with the aid of 300 colleagues who were persuaded to sit on a toilet in private and to mark the positions of their anuses by fixing a small piece of a paper to a wire strung across the seat. The average location of the female vulva was measured in a strip club. [8] In 1987, TOTO launched the first integrated Washlet.
In 1992, TOTO launched the Neorest, a tank-less toilet with an integrated Washlet. Other manufacturers started producing electronic bidets, without the trademarked term "washlet". Following a toilet-paper shortage arising from the COVID-19 pandemic, the Australian Consumers Association published a discussion of the merits of bidets and "smart toilets", including a wide range of detachable bidet seats. [9]
Following the 2024 CrowdStrike incident, a widely viral post on Japanese social media site Misskey stated: "強制再起動で尻の穴壊されかけました" [10] , meaning roughly "Forced reboot almost destroyed my asshole". The accompanying pictures showed the bidet displaying a Microsoft Windows blue screen of death that the user then force-rebooted.
Electronic bidets have been featured in the Simpsons and Futurama as "Japanese Toilets". [11]
A bathroom is a room in which people wash their bodies or parts thereof. It can contain one or more of the following plumbing fixtures: a shower, a bathtub, a bidet, and a sink. The inclusion of a toilet is common. There are also specific toilet rooms, only containing a toilet, which in North American English tend to be called "bathrooms", "powder rooms" or "washrooms", as euphemisms to conceal their actual purpose, while they in British and Irish English are known as just "toilets" or possibly "cloakrooms" - but also as "lavatories" when they are public.
A bidet is a bowl or receptacle designed to be sat upon in order to wash a person's genitalia, perineum, inner buttocks, and anus. The modern variety has a plumbed-in water supply and a drainage opening, and is thus a plumbing fixture subject to local hygiene regulations. The bidet is designed to promote personal hygiene and is used after defecation, and before and after sexual intercourse. It can also be used to wash feet, with or without filling it up with water. Some people even use bidets to bathe babies or pets. In several European countries, a bidet is now required by law to be present in every bathroom containing a toilet bowl. It was originally located in the bedroom, near the chamber-pot and the marital bed, but in modern times is located near the toilet bowl in the bathroom. Fixtures that combine a toilet seat with a washing facility include the electronic bidet.
A toilet seat is a hinged unit consisting of a round or oval open seat, and usually a lid, which is bolted onto the bowl of a toilet used in a sitting position. The seat can be either for a flush toilet or a dry toilet. A toilet seat consists of the seat itself, which may be contoured for the user to sit on, and the lid, which covers the toilet when it is not in use – the lid may be absent in some cases, particularly in public restrooms.
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers have temperature, spray pressure and adjustable showerhead nozzle. The simplest showers have a swivelling nozzle aiming down on the user, while more complex showers have a showerhead connected to a hose that has a mounting bracket. This allows the showerer to hold the showerhead by hand to spray the water onto different parts of their body. A shower can be installed in a small shower stall or bathtub with a plastic shower curtain or door. Showering is common due to the efficiency of using it compared with a bathtub. Its use in hygiene is, therefore, common practice.
A squat toilet is a toilet used by squatting, rather than sitting. This means that the posture for defecation and for female urination is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not.
Toilets in Japan are sometimes designed more elaborately than toilets commonly seen in other developed nations. European toilets occasionally have a separate bidet whilst Japan combines an electronic bidet with the toilet. The current state of the art for Western-style toilets in Japan is the bidet toilet, which as of March 2016 is installed in 81% of Japanese households. In Japan, these bidets are commonly called washlets, a brand name of Toto Ltd., and they may include many advanced features rarely seen outside of Asia. The basic feature set commonly found on washlets consists of anal hygiene, bidet washing, seat warming, and deodorization.
Washlet is a Japanese line of cleansing toilet seats manufactured and sold by the company Toto. The electronic bidet features a water spray element for genital and anal cleansing. and commonly appears on toilets all over Japan. The device was released in June 1980 and as of January 2022, Toto has sold more than 60 million units.
Toto Ltd., formerly known as Tōyō Tōki, and Tōtō Kiki, is a Japanese multinational toilet manufacturer which is known for manufacturing the Washlet. TOTO was founded in 1917. The company is based in Kitakyushu, Japan, and owns production facilities in nine countries.
A gas duster, also known as tinned wind or compressed air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water.
Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a mechanical pressure washer is expressed in gallons or liters per minute, often designed into the pump and not variable. The pressure, expressed in pounds per square inch, pascals, or bar, is designed into the pump but can be varied by adjusting the unloader valve or using specialized nozzle tips. Machines that produce pressures from 750 to 30,000 psi or more are available.
A sitz bath or hip bath is a bathtub in which a person sits in water up to the hips. It is used to relieve discomfort and pain in the lower part of the body, for example, due to hemorrhoids (piles), anal fissures, perianal fistulas, rectal surgery, an episiotomy, uterine cramps, inflammatory bowel disease, pilonidal cysts and infections of the bladder, prostate or vagina. It works by keeping the affected area clean and increasing the flow of blood to it.
A toilet brush is a tool for cleaning a toilet bowl.
An oil burner is a heating device which burns #1, #2 and #6 heating oils, diesel fuel or other similar fuels. In the United States, ultra low sulfur #2 diesel is the common fuel used. It is dyed red to show that it is road-tax exempt. In most markets of the United States, heating oil is the same specification of fuel as on-road un-dyed diesel.
Anal hygiene or anal cleansing refers to the practices that are performed on a person's anus to maintain hygiene, usually in the aftermath of defecation. Post-defecation cleansing is rarely discussed academically, partly due to the social taboo surrounding it. The scientific objective of post-defecation cleansing is to prevent exposure to pathogens. The process of post-defecation cleansing involves washing the anus and inner part of the buttocks with water. Water-based cleansing typically involves either the use of running water from a handheld vessel and a hand for washing or the use of pressurized water through a jet device, such as a bidet. In either method, subsequent hand sanitization is essential to achieve the ultimate objectives of post-defecation cleansing.
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as blackwater and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
A bidet shower—also known as a handheld bidet, commode shower, toilet shower, health faucet, bum shower, jet spray, hand shower, Muslim shower, shatafa or bum gun—is a hand-held triggered nozzle that is placed near the toilet and delivers a spray of water used for anal cleansing and cleaning of the genitals after using the toilet for defecation and urination, popularised by Arab nations where the bidet shower is a common bathroom accessory. The device is similar to that of a kitchen sink sprayer.
A toilet is a small room used for privately accessing the sanitation fixture (toilet) for urination and defecation. Toilet rooms often include a sink (basin) with soap/handwash for handwashing, as this is important for personal hygiene. These rooms are typically referred to in North America as half-bathrooms in a private residence.
The tabò is the traditional hygiene tool primarily for cleansing, bathing, and cleaning the floor of the bathroom in the Philippines, Indonesia, East Timor, Malaysia, Vietnam and Brunei. Tabò is the Filipino name, while gayung and cebok are the equivalent terms used in Indonesia, Brunei, Malaysia, and East Timor. Its Vietnamese name is thau tắm or chậu nước. The tabò could most commonly be in found rural areas though it is also widely used in cities. The word may be related to the word cebok in Indonesia and Malaysia, which describes the process of cleansing oneself using a tabò in a mandi.
A deodorizing toilet seat is a toilet seat that comes with integrated air purifier and air freshener solutions to combat bad odors.
An intelligent toilet or smart toilet is a bathroom plumbing fixture or type of electronic bidet toilet which incorporates traditional bidet cleansing, with the added enhancement of modern SMART home technology.
