JPH0657802A - Washing water temperature control device provided with washing water function for heated seat - Google Patents

Abstract

PURPOSE:To carry out temperature control for obtaining comfortable temperature of the washing water conforming to the temperature sensible to the user's body by setting the temperature slightly to the warmer side if the seasonal temperature is low even if the room temperature is high by making reference to the combination of the seasonal temperature of the four seasons and the temperature of the room where a heated seat is installed. CONSTITUTION:For the purpose of setting the temperature of washing temperature calculation circuit 1, which presumes one of the four seasons based on the average temperature of a few days up to previous day, and from a room temperature judgement circuit 2, which detects the temperature of the room where a heated seat 6 provided with a washing water function is installed, by combining both circuits together is input into a washing water temperature setting circuit 3. A washing water heater 5 is energized by means of an output from a washing water temperature adjusting circuit 4 which may adjust the temperature of the washing water set by the washing water temperature setting circuit 3 to same appropriate temperature.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wash water temperature control device for controlling the temperature of wash water in a heated toilet seat having a wash water function.

[0002]

2. Description of the Related Art Conventionally, a cleaning water temperature control device for a heating toilet seat equipped with this type of cleaning water function has a switch set in several stages corresponding to the room temperature of the room in which the heating toilet seat is installed. The temperature of the wash water is controlled by changing the current applied to the thermistor by increasing or decreasing the current.

[0003]

SUMMARY OF THE INVENTION In the conventional washing water temperature control device for a heated toilet seat having such a washing water function,
For example, in spring-summer-autumn-winter or day and night, there are individual differences in that even with the same wash water temperature, some people do not feel the same warmth temperature. There is a problem in that some people may feel discomfort because the temperature of the wash water cannot be adjusted because it is not based on the temperature.

A cleaning water temperature control device for a heating toilet seat having a cleaning water function according to the present invention solves the above-mentioned problems, and is equipped with a seasonal temperature of spring, summer, autumn and winter and a heating toilet seat. By referring to the room temperature in combination with the room temperature, if the room temperature is high but the seasonal temperature is low, set a slightly warmer temperature, or, for example, in the spring, when the seasonal temperature gradually increases. In this case, the temperature is set to match the thermal sensation of spring, and the temperature is controlled so that the temperature of the wash water is comfortable according to the sensible temperature of the user.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, a cleaning water temperature control device for a heated toilet seat equipped with a cleaning water function according to the present invention is used to measure the average temperature in the several days up to the previous day to the seasons of spring, summer, autumn and winter. The output obtained by combining the seasonal temperature calculation circuit for estimating and the room temperature determination circuit for determining the room temperature of the room where the heated toilet seat with the wash water function is installed is input to the wash water temperature setting circuit, The output of the cleaning water temperature adjusting circuit for adjusting the temperature of the cleaning water set by the cleaning water temperature setting circuit to an appropriate temperature is input to the cleaning water heater to energize the cleaning water heater. It controls the current.

[0006]

Next, the operation of the temperature control device for the wash water of the heated toilet seat having the wash water function according to the present invention will be described. The spring, summer, autumn, and winter seasons are estimated from the average temperature over the several days up to the previous day, and the seasonal temperature estimated from the average temperature and the room temperature at the present time of the room where the toilet seat is installed is combined. By referring to this, the temperature of the wash water is calculated and the optimum temperature of the wash water is set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a cleaning water temperature control device for a heated toilet seat having a cleaning water function according to the present invention will be specifically described below with reference to the drawings. FIG. 1 is a control operation block diagram of a flush water temperature control device for a heated toilet seat having a flush water function according to the present invention. In this figure, the seasonal temperature calculation circuit 1 for estimating the season of spring, summer, autumn and winter from the average temperature (hereinafter referred to as the seasonal temperature) for several days until the previous day (for example, 5 to 10 days is optimum) and the cleaning water function are shown. It was obtained by combining the seasonal temperature calculation circuit 1 and the room temperature determination circuit 2 in order to set the temperature of the wash water from the room temperature determination circuit 2 that detects the room temperature of the room in which the equipped heating toilet seat 6 is installed. The output is input to the wash water temperature setting circuit 3 and heating is performed by the output from the wash water temperature adjusting circuit 4 for adjusting the temperature of the wash water set by the wash water temperature setting circuit 3 to an appropriate temperature. Wash water heater 5 installed on the toilet seat 6
The temperature of the washing water is automatically controlled by increasing / decreasing the current applied to the.

Here, an example of the control operation of the washing water temperature control device for the heating toilet seat having the washing water function according to the present invention will be described with reference to the graph showing the relationship between the room temperature and the washing water temperature shown in FIG. explain. For example, the seasonal temperature until the day before is 15
If it is assumed that the room temperature of the room where the heated toilet seat having the washing water function is installed is 25 ° C, the temperature of the washing water is set to 38 ° C. If the average seasonal temperature for the several days up to the previous day is 25 ° C (summer), the room temperature of the room where the heated toilet seat with the flush water function is installed is 25 ° C as in the case of winter. However, the temperature of the wash water is controlled to be 35 ° C.

In this way, the seasonal temperature of spring, summer, autumn, and winter is estimated from the average temperature for the several days up to the previous day, and the estimated seasonal temperature and a heating toilet seat having a flush water function are installed. The temperature of the wash water is automatically set by calculating the optimum temperature of the wash water of the heated toilet seat by referring to this combined with the present room temperature of the room.

[0010]

The cleaning water temperature control device for a heated toilet seat having the cleaning water function according to the present invention is constructed as described above and has the following effects. In other words, refer to both the room temperature and the seasonal temperature by combining the seasonal temperatures that change depending on the seasons of spring, summer, autumn, and winter without being affected only by the room temperature of the room where the heated toilet seat with the cleaning function is installed. This makes it possible to set a comfortable temperature for the wash water, and the temperature of the wash water may be too high in the summer or too low in the winter, causing the user of the heated toilet seat to feel uncomfortable. It has the feature that it can be controlled to a comfortable wash water temperature according to the user's sensible temperature during spring, summer, fall, winter, or day and night.
