Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sanitary cleaning device that cleans the private parts of a human body sitting on a toilet seat with water and dries them with warm air.

Conventional configurations and their problems Conventional sanitary cleaning devices have mainly been configured to heat the toilet seat surface, which is made of plastic, by heating it from the back side of the toilet seat to warm the surface of the toilet seat that comes in contact with the wide area. However, because the heater starts up slowly, even if you turn on the heater just before you sit down, it won't warm up completely, and you'll often feel cold and uncomfortable the moment you sit down, or you'll end up using it before you can get the full warming effect. Therefore, it was customary to use the device with electricity turned on all day long. However, considering the short usage time of the toilet seat, this was a wasteful use of energy, and improvements were desired.

OBJECT OF THE INVENTION The present invention solves such conventional problems, and aims to provide a sanitary cleaning device that consumes zero energy for heating when the sanitary cleaning device is not in use, and allows a warm toilet seat to be used when the sanitary cleaning device is in use. It is something to do.

Structure of the Invention In order to achieve this object, the present invention provides a conventional sanitary washing device having a hot air drying means, a lid closure detection means for detecting that the lid is closed, and a human body in a room where a toilet bowl is installed. The drying device is provided with an indoor human body detection means for detecting the indoor human body detection means, and a drying energizing means for energizing the drying means by an earned signal from the lid closing detection means and the indoor human body detection means.

With this configuration, when the user enters the room, the drying means is automatically activated, and the surface of the toilet seat is rapidly heated by passing hot air through the gap between the lid and the toilet seat. When the user takes down his underwear and opens the lid, the drying means is automatically deactivated, allowing the user to comfortably sit on the heated toilet seat.

By closing the lid after use, the above operation will be repeated the next time it is used.

, the heater 16, and the like. Reference numeral 23 denotes a storage box that rotatably supports the toilet seat 3 and M5 and houses the various means described above.

FIG. 3 is a control block diagram of the same device, in which reference numeral 24 is a cleaning switch for energizing the cleaning means of the pump 12 to turn the cleaning ON/OFF, and 25 is a front motor 15 and a heater 16. A drying switch that energizes the drying means 26 to turn ON/OFF local drying after cleaning; 27 is an indoor human body detection means consisting of the infrared sensor 19 and an amplification discriminator 28; 29 is built in the toilet seat 3; The toilet seat heating means consists of a heater, 30.31 is an inverter circuit, 32 and 33 are AND gate circuits, and No. 4 is an OR gate circuit. Further, 35 is a toilet seat temperature detection means comprising the temperature sensor 4, the temperature setting device 36, and the amplification discriminator 37.

In the above configuration, when the lid 5 is closed and there is no user in the room where the toilet bowl 1 is installed, that is, when the sanitary washing device is not in use 9 state, there is no input to the infrared sensor 19, and the indoor human body The output from the detection means 27 is LOW. Therefore, the drying means 26 and the toilet seat heating means are not energized, and the energy consumption of the heating tank is zero.

At this time, the water heating means 10 maintains the washing water at an appropriate temperature.

Now, when a person enters the room, it is immediately detected by the infrared sensor 19, and the output of the indoor human body detection means 27 becomes Hi.
Changes to At this time, if the temperature of the toilet seat 3 is lower than the set temperature, the output of the toilet seat temperature detection means 35 is Low;
Therefore, the output of the inverter circuit 3o is Hi, and the output of the lid closure detection means 6 is also Hi, so the output of the AND gate circuit 33 becomes Hi, and the drying means 26 is energized to increase the temperature. Warm air 1 from wind outlet 13
8 is blown out, and the hot air hits the back side of the lid 5 and then passes through the gap between the lid 5 and the toilet seat 3. Therefore, the upper part of the toilet seat 3 is rapidly heated by the flowing hot air. At the same time, the output of the AND gate circuit 32 becomes Hi, so the toilet seat heating means 29 is also energized to heat the toilet seat from the inside. During this time, the temperature of the toilet seat 3 is monitored by the toilet seat temperature detection means 35, and the output of the inverter circuit 3o is set to Hi-Low to prevent overheating and maintain the temperature at the set temperature. When the user enters the room and after preparatory work such as opening and closing the room door and taking down underwear, attempts to lift the lid 5.
It can be opened easily by the action of the clutch 7, and when opened, the output of the lid close detection means 6 becomes Low and the drying means 26 is deenergized. At this time, the toilet seat heating means 29
continues to be energized to maintain the toilet seat 1 at the set temperature. After sitting on the toilet seat 3, if the user wishes to clean the toilet, he or she can activate the cleaning means 12 using the cleaning switch 24 to perform cleaning.

When drying is performed after washing, the drying means 26 can be energized by the drying switch 25 at any time to perform drying. When the user leaves the room after washing and drying,
Since the input to the infrared sensor 19 disappears, the output of the indoor human body detection means 27 changes to Low, and the output of the inverter circuit 31 becomes Hl, which energizes the lid closing means 8 for a short time and automatically closes the lid. When the lid 5 is closed, the toilet seat heating means 29 is also deenergized, and the heating energy use state returns to zero, waiting for the next use of the sanitary cleaning device.

According to this configuration, the surface of the toilet seat is heated by the warm air the moment the user enters the room, so the surface of the toilet seat that comes into contact with the user's arm is heated rapidly, and therefore the user does not enter the room. It is also possible to raise the toilet seat to a warm blood setting of 1 during the necessary preparation time of about 5 seconds, from the time the toilet door is opened and closed until the user finishes taking down his underwear, allowing the user to use the toilet seat at the appropriate temperature from the moment he or she sits down. It is something. Moreover, since the warm air that rapidly warms the toilet seat is obtained by energizing the drying means of a conventional sanitary cleaning device, the mechanism is not particularly complicated and can be achieved at low cost. Furthermore, when the user opens the lid to sit on the toilet seat 1, the drying means is automatically deenergized by the action of the lid closure detection means, so hot air will not blow out when not in use.
Also, during drying, the drying means can be energized at any time by means of a drying switch. Further, when the user is sitting on the toilet seat 3, the toilet seat heating means can continue to collect the temperature. In addition, when the user finishes using the sanitary washing device and leaves the room, the drying means and the toilet seat heating means are automatically deenergized. is zero, and the energy saving effect is significant. Moreover, since the lid 5 is automatically closed and the toilet seat 1 is ready to be rapidly heated by warm air when the user next enters the room, the user can obtain comfortable warmth every time he uses the toilet. In addition, when the lid 5 is closed,
By structuring the lid 5 such that a cavity is formed between the top of the toilet seat 3 and the lid 5 through which warm air can easily pass, a movable damper is also provided so that the hot air blows out in an upward direction when the lid is closed. By providing this, the surface of the toilet seat is heated more rapidly, and the immediate heating effect is improved. For people who can feel satisfied by only preventing the cold sensation they experience at the moment they sit on the toilet seat 3, there is no need for toilet seat heating means, and if you do not use a large capacity heater, it will not overheat. 71 is not necessary to control the heater by the toilet seat temperature detection means, and furthermore, if the sanitary washing device can be remembered to close the lid after using it, a lid closing means is not particularly required. It is not limited to.

Effects of the Invention The sanitary cleaning device of the present invention is a conventional sanitary cleaning device that has a warm air drying device, but also includes a lid closure detection device that detects whether the lid is closed, and a human body in a room where a toilet bowl is installed. An indoor human body detection means, and a drying energizing means for energizing the drying means by an AND signal of the lid closing detection means and the indoor human body detection means, and the drying means is automatically energized when a user enters the room. The warm air passes through the gap between the lid and the toilet seat, rapidly heating the surface of the toilet seat, and when the user takes down their underwear and opens the lid, the drying means is automatically deenergized and the user is warmed up. You can use the sanitary cleaning device while sitting on the toilet seat, and after use, you can close the lid and leave the room and repeat the above operation the next time you use it. Since it is obtained by energizing the drying means of the sanitary washing device, the mechanism is not particularly complicated, and toilet seat heating can be performed at low cost even in sanitary washing devices that conventionally did not have toilet seat heating.

2. Electrical energy consumption required for heating is limited to the short period from when the user enters the room to when the lid is opened, so the energy saving effect is extremely high.

3. Since the surface of the toilet seat is directly heated with dry hot air that flows at a high speed, the heating start-up of the top part of the toilet seat where the wide area comes into contact is extremely fast, and the dry warm air starts blowing out from the moment the user enters the room. , it is possible for the user to blink the top of the toilet seat during the short preparation period from preparatory tasks such as opening and closing the room door and lowering underwear to opening the lid, so the user can feel comfortable the moment he or she sits down. It has features such as 〇, which allows you to feel a sense of warmth.
