Abstract

PURPOSE:To prevent electricity from being wastefully consumed by discriminating the opened or closed state of windows and doors according to the degree of a room temperature rising-speed after heating operation start, and by determining the continuing or stopping of the heating operation. CONSTITUTION:A room temperature detected by a room temperature sensor 4, and a heating temperature set by a variable resistance 10 are compared with each other, and when the room temperature is lower, then a fan motor 2 and a heater 3 are electrified, and a control section 9 for generating warmed air is set. After that, a time after warmed air generation is counted at a timer count section 7, and the arithmetic means 8 of a room temperature rise rate for performing arithmetic on a room temperature rise speed after the lapse of a fixed time based on the lapse time and the temperature signal of the sensor 4 is set. After that, a room temperature rise rate discriminating means 19 is set, and a previously stored constant and a room temperature rise speed processed by the means 8 are compared with each other. When the room temperature rise speed is higher than the constant, then the heating operation is continuously kept, and when the speed is lower, then it is discriminated that windows or the like are opened, and operation is stopped, and an alarm 11 is worked. As a result, electricity can be prevented from being wasted, and one can know that the windows or the like are opened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to heating of a toilet device with a warm air function used for home use.

[0002]

2. Description of the Related Art A conventional toilet device of this type has been developed as follows.
The configuration shown in Japanese Patent Laid-Open No. 8-62999 has been common. The configuration will be described below with reference to FIGS. 4 and 5.

When the heating switch 1 is turned on, the main body case 2
The fan motor 3 and the heater 4 built in the heater are energized, and hot air is generated from the hot air outlet 5 to heat the inside of the toilet.

[0004]

However, in the above-mentioned configuration, if the window or door in the toilet is forgotten to be tightened and the heating operation is performed with the window open, the electricity cost is wasted without heating the inside of the toilet. There was a problem.

The present invention solves the above-mentioned problems of the prior art. When the window or door in the toilet is forgotten to be tightened during heating operation,
The purpose is to automatically stop the operation, inform the user of that, and prevent wasteful consumption of electricity.

[0006]

In order to solve the above problems, a toilet device of the present invention comprises a room temperature detecting device for detecting room temperature, a timer for counting time, a hot air generating device for heating the room, and the warming device. A room temperature increase rate calculation means for calculating the room temperature increase rate from the room temperature after the start of operation of the wind generator and the room temperature after a lapse of a certain time, and the operation of the warm air generator is controlled based on the calculation result of the calculation means. , And a control unit for generating an alarm signal.

[0007]

According to the present invention, the operation of the hot air generator is controlled by judging whether the window or door in the toilet is opened or closed depending on whether the room temperature rising speed after the heating operation is started is large or small.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, when the room temperature setting knob 13 is operated, the position of the variable resistor 10 is determined, and the desired toilet heating temperature is set. Turn on the operation switch 1,
If the room temperature detected by the room temperature sensor 4 at the air intake port 15 is lower than the set temperature, the microcomputer 6
The control unit 9 compares the signal voltages of the room temperature sensor 4 and the variable resistor 10 and operates the relay 5 to close the relay contact 5a. As a result, energization of the fan motor 2 and the heater 3 is started, hot air is generated from the hot air outlet 14, and heating of the inside of the toilet is started. At this time, the timer count section 7 in the microcomputer 6 starts counting time, and at the same time, the room temperature increase rate calculating means 8 is based on the signal from the room temperature sensor 4 and the elapsed time counted by the timer count section 7. Te, room temperature rising speed after a predetermined time (t min) has elapsed _{m = (T-T O)} / t T: room temperature after t minutes lapse T _O: calculating the room temperature immediately after the start of heating operation. Then, the room temperature increase rate determining means 19 calculates the constant a stored in advance and the room temperature increase rate calculating means 8
The room temperature rising speed m obtained in step S3 is judged to be larger or smaller, and the control unit 9
Controls the signal to the relay 5 to determine whether the heating operation is continued or stopped.

The room temperature increase rate m is the microcomputer 6
When it is larger than the constant a stored therein, the heating operation is continued, and when the room temperature sensor 4 becomes equal to the room temperature set value, the power supply to the fan motor 2 and the heater 3 is stopped. On the contrary, when it is smaller than a, the heating operation is stopped and the alarm device 11 is controlled to operate at the same time.

In FIG. 3, heater power consumption is 700 watts, toilet dimensions are width 1.0 x depth 1.2 x height 2.0 m, and outside temperature is 5
Shown are the results of room temperature rise during heating of the toilet when the room temperature is 10 ° C and the initial room temperature is 10 ° C. The temperature rises by 7 ° C in 10 minutes, and the room temperature rise rate is m = 0.7. If the constant a to be stored in the microcomputer is set to about 0.05, the microcomputer can automatically determine whether or not the room temperature has definitely risen after the heating operation is started. In other words, on a cold winter day, if the window or door in the toilet is open, the room temperature rise rate is extremely slow, and the room temperature rise rate m is 0.05.
It becomes smaller and the heating operation can be stopped automatically.

[0011]

As described above, according to the toilet device of the present invention, the following effects can be obtained. (1) By detecting the room temperature rise rate after the start of heating operation, it is possible to know whether the inside of the toilet is open to the outside, and heating is automatically stopped when windows and doors are open or when the ventilation fan is activated. It is possible to prevent wasting of useless electricity bills. (2) When the window is open and the rate of room temperature rise is slow,
The alarm device is activated so that the user can know that the window is open.
