Abstract

PURPOSE:To make it possible to carry out a heating also in a toilet by installing a heat radiating part as a circuit of washing water, and a hot air blower on hot water wash seats which spray private parts with hot washing water from their nozzles. CONSTITUTION:When an operation is made to stop washing, a motor-driven pump 2 stops, a nozzle 9 retracts with spring energization, both solenoid valves V1, V2 are changed over an a hot water tank 3 is connected to a hot water mat 6. Next, when the motor-driven pump 2 is operated in a condition where the hot water tank 3 is connected to the hot water mat 6, the washing water kept hot in the hot water tank 3 flows to the hot water mat 6 through the solenoid valve V2 and returns back to the hot water tank 3 through the solenoid valve V1. As a result, heating at one's feed can be achieved by the circulation of hot water to the hot water mat 6 installed on the floor around a closet, so that heating can be carried out without requiring any separate hot-air heater.

Description

[Detailed description of the invention] [Industrial application field]

The present invention provides a warm water washing toilet seat for cleaning the anal area after using the toilet, or for cleaning the female private parts during errands or menstruation.

[Conventional technology]

Warm water flushing toilet seats clean private parts by spraying warm water from a nozzle onto the private parts, and the demand for them has increased significantly in recent years due to their comfort.

[Problem to be solved by the invention]

On the other hand, warm air heaters for toilets are now on the market as a way to make toilets more comfortable, and these are also enjoying a boom. However, placing such a heater inside the toilet takes up space inside the toilet, which is already small. The present invention has been developed in view of these difficulties, and its purpose is to provide a toilet seat with a warm water bidet that can also heat the interior of the toilet.

[Means to solve the problem]

Therefore, the warm water flushing toilet seat according to the present invention is a warm water flushing toilet seat that sprays heated flushing water from a nozzle toward private parts, and is equipped with a heat radiating section as a circulation path for the heated flushing water. It has the first feature, and is also characterized in that it includes a hot air blower. According to the first feature of the present invention, heating can be performed using hot washing water, and according to the second feature, it can also be used for drying after washing private parts. Heating can be performed by a hot air blower that can be used. <Embodiment> The present invention will be explained below based on the illustrated embodiment. As shown in FIG. Toilet seat 7
and a toilet seat cover 8, and is configured to be able to be installed in place of the toilet seat cover and toilet seat of an existing seat-type toilet. As shown in FIG. 2, the cleaning device main body 1 is equipped with an electric pump 2 and a hot water tank 3, as well as a nozzle 9. A low tank 18 or a sub-tank is connected to the electric pump 2 through a solenoid valve V. and a hot water tank 3, and the hot water tank 3 is further connected to a nozzle 9 via a solenoid valve 2. Further, both of the solenoid valves V, , V are three-way valves, and both ends of a hot water maturo serving as a heat radiation section are connected to the two solenoid valves V, , V. 30 in the figure is a hot water tank 3 31 is a temperature detection unit consisting of a thermistor for detecting the temperature of the washing water, and these are used together with the solenoid valves V + and V 2, the electric pump 2, and the toilet seat switch S. , as shown in FIG. 4, is connected to a control circuit C, and the cleaning water in the hot water tank 3
As shown in FIG. 3, the set temperature is achieved by on/off control of the hot water heater 30. Therefore, in this hot water washing toilet seat, when the toilet seat switch S is operated to instruct private parts to be washed, the solenoid valve Vl connects the low tank 18 and the electric pump 2, and the solenoid valve V2 connects the hot water tank 3. The low tank 18 is connected to the nozzle 9 and the electric pump 2 is operated.
Water is sent from the hot water tank 3 to the hot water tank 3, and at this time, the hot wash water in the hot water tank 3 is pushed out and flows through the nozzle 9.
The cleaning water reaching the nozzle 9 extends the nozzle 9 against the force of the spring, and then jets out from the tip of the nozzle 9 to clean the private parts, thereby performing a cleaning stop operation. If so, the electric bong 12 is stopped and the nozzle 9 is compressed by the spring force, and both electromagnetic valves V1. V2 switches and connects hot water Matsutoro to hot water tank 3. When the electric pump 2 is operated with the hot water Matsutoro connected to the hot water tank 3, as shown by the arrow in Fig. 2, the hot water in the hot water tank 3 is flushed through the solenoid valve ■2. After the hot water flows into Matsutoro through the solenoid valve ■,
The warm water is returned to the hot water tank 3 through the toilet bowl, and the warm water is circulated to the warm water pine l-6 installed on the floor around the toilet bowl, thereby heating the feet. The circulation of hot water between the hot water tank 3 and the hot water tank 3 may be kept running at all times so that the user's feet are warm no matter when they use the toilet, but the electric pump 2 may be operated intermittently. It is preferable that the hot water be circulated intermittently.In this case, a detection means such as a limit switch to detect when a person has sat on the toilet seat 7 is provided, and the detection means It is even more preferable if the electric pump 2 is operated continuously while the output is being produced. By the way, since the temperature of the hot water in the hot water tank 3 is set to be suitable for private parts washing, if this is used for hot water heating, the warmth may not be enough in terms of heating. In this case, as shown in Figure 5,
Two types of temperature settings can be made: a cleaning hot water set temperature T, and a circulating set temperature T1, and the cleaning water in the hot water tank 3 is normally set at a circulating set temperature T, which is higher than the cleaning hot water set temperature 'F2. is heated and circulated in the warm water pine 1-6, and when it detects that the user has sat on the toilet seat 7 (at point 1 in the figure), the set temperature changes to the wash hot water setting. It is advisable to switch the temperature to T2.Since the hot water Matsutoro is already sufficiently warmed when the seating is detected as described above, the circulation of hot water to the hot water Matsutoro may be stopped at this point6. T may be set freely by the user. If the time t required for the temperature of the wash water to drop from the circulation set temperature T1 to the wash hot water set temperature T2 is long, there is a risk that wash water at a temperature higher than the wash hot water set temperature T may be spouted out at the start of cleaning. . In this case, when it is detected that a person is sitting down, the solenoid valves V+ and V2 are switched to connect the low tank 18 and the electric pump 2, and the hot water tank 3 and the nozzle 9, and in this state, the electric pump is operated at low speed. It is a good idea to run the hot water tank 3 through the nozzle 9.
By discharging water from the hot water tank 3 and introducing water therein, the temperature of the cleaning water in the hot water tank 3 is rapidly lowered to the cleaning hot water set temperature T2. Note that the operating speed of the electric pump 2 at this time is such that the cleaning water does not jet out from the nozzle 9, but drips down. If a heat storage material is placed in the hot water maturo to surround the passage of hot water, the operation interval of the electric pump 2 can be made longer or the operation time can be made shorter, which is economical. Furthermore, if a far-infrared material that emits far-infrared rays when heated is provided on the surface of the hot water maturo, heating will be made more effective. In this case, it is preferable to form not only a hot water radiator but also a vertically shaped heat dissipating member and provide it with a far-infrared material. In addition, here we have shown a system in which hot flush water is circulated to the hot water matsutoro, but a circulation path is formed in the toilet seat 7 and the toilet seat 7 is heated.
In warm water bidet toilet seats, which may be configured to circulate hot water throughout the room, an electric toilet seat heater is generally built into the toilet seat 7. can be supplied. Another embodiment is shown in FIG. 6 and below. Here, a hot water tank 3 for heating the cleaning water to be supplied to the nozzle 9 is provided on one side of the cleaning device main body 1, and a hot air blower 5 is provided on the other side. ing. This hot air blower 5 has a motor 5 as shown in FIG.
It consists of a fan 51 driven at zero and a hot air heater 52, and the hot air sent out from here
5, the drying vent 53 and the heating vent 54 are opened.
It is designed so that it can be divided into As shown in FIG. 6, the heating air vents 54 here are opened on both sides of the cleaning device main body 1 facing forward and slightly downward, and blow hot air to the feet of the user. It is ready to send. The damper 55 is biased by a spring 56 to normally send warm air to the heating air outlet 54 as shown in FIG. 9, and after cleaning the private parts, the toilet seat switch S
When the drying switch is operated, the damper motor 57 is activated and the wire 5 connected to the damper 55 is activated.
8 and move the damper 55 against the spring 56 as shown in FIG. 8 so that warm air is sent to the drying air outlet 53 side. This allows a single warm air blower 5 to perform drying of the private parts after washing and hot air heating. 59 in FIGS. 8 and 9 is a suction port. As shown in Figures 6 and 7, the interior of the toilet seat 7 is
The toilet seat heater 71 for heating the toilet seat is housed in the upper part, a hot air passage is formed in the lower part, and the toilet seat 7 is divided into layers.
A plurality of heating vents 54 that open downward may be provided on the outer periphery of the heater. In this case, you will be exposed to warm air no matter where you put your feet. Further, since the air is warmed by the toilet seat heater 71, the output of the hot air heater 52 may be small. Conversely, if a heat storage material is placed inside the toilet seat 7 instead of the toilet seat heater 71, the heat storage material is warmed by the hot air, so the toilet seat 7 can be kept warm even without the toilet seat heater 71. In place of the hot air heater 52 in the hot air blower 5, a hot water tank 3 may be used.
Heat-generating components such as transistors for controlling the hot water heater 30 are also arranged around the hot water tank 3 which is maintained at ~42°C, and an air duct connected to the hot air outlet 54 surrounds the hot water tank 3. Let's do it like this. In this case, the hot air outlet 54 is only on the hot water tank 3 side, but since the hot air heater 52 and its control parts can be eliminated, a significant cost reduction can be achieved.

【Effect of the invention】

As described above, in the first feature of the present invention, since the heat radiating section is provided as a circulation path for heated washing water, hot water can be generated by circulating the heated washing water through the heat radiating section. According to the second feature, the heating can be performed by a hot air blower that can be used for drying after washing private parts, and However, heating can be performed without the need for a separate hot air heater.
