Description

  The present invention relates to a toilet apparatus for heating a toilet seat in a short time.

  Conventionally, in this type of heated toilet seat, as shown in FIG. 10, the seat portion 103 of the toilet seat 102 having a hollow portion 101 is made of a transparent polypropylene resin, and a radiant heat absorption layer 104 is installed on the surface of the seat portion 103. A lamp heater 105 was installed in the cavity 101. The radiant heat from the lamp heater 105 is transmitted through the seating portion 103 made of transparent polypropylene resin, converted into heat by the radiant heat absorption layer 104 on the surface, and the temperature of the seating portion 103 is increased. Since heat is generated in the radiant heat absorption layer 104 in contact with the buttocks, heating of the buttocks can be performed in a short time compared to a method in which heat is conducted from the inside of the toilet seat 102 using a cord heater or the like. Further, the temperature control was performed by a thermostat 106 placed in the vicinity of the lamp heater 105, and the risk of abnormal heating was prevented by the temperature fuse 107 (see, for example, Patent Document 1).

JP 2000-14598 A

  However, in the above-mentioned conventional configuration, the lamp heater has good power conversion efficiency, so it has a quick warming performance that warms up quickly and can raise the temperature in a short time, but the resistance value of the lamp heater is cooled by the filament ( When the temperature is equivalent to the temperature in the toilet room), a large inrush current flows at the beginning of energization because it is as small as 1/10 or less of the rated power consumption. Of course, the resistance value of the filament reaches the rated resistance in a short time, and the inrush current is immediately suppressed, but for use in the toilet device, it is energized simultaneously with other heaters equipped in the toilet device. In this case, a larger current flows.

  In general, the indoor power wiring into the toilet room is not a large current wiring and is a single power wiring, and therefore there are often no earth leakage circuit breakers and overcurrent circuit breakers that assume a large current. In addition, there are many things that are taken from the same power wiring to the lighting fixtures in the toilet room, and when a heater such as a warm water heater that heats the washing water for washing the local body part of the lamp heater and the toilet device is energized at the same time, The circuit breaker will drop due to overcurrent, or the voltage drop will occur due to the resistance component of the indoor power wiring, the supply voltage to the toilet device and the toilet room lighting will decrease, and the product performance of the toilet device will deteriorate. Or has a problem that the brightness of the interior lighting decreases.

A hot water heater for heating the washing water to be washed and a control means for energizing the toilet seat heater when the human body is detected by the human body detecting means and for stopping the energization to the hot water heater while the current is being energized. It is a thing.

  As a result, the toilet seat is warmed only when the human body is seated to save energy, and when the toilet seat heater is energized, the energization of the hot water heater is stopped, which is rich in energy savings and improves usability.

  The toilet apparatus of the invention heats a toilet seat having a immediately heated toilet seat heater such as a lamp heater that generates thermal energy in the cavity, human body detecting means for detecting the presence or absence of a human body, and washing water for cleaning a human body local part. A hot water heater, an energization amount calculating means for calculating a total energization amount of the toilet seat heater and the hot water heater, and energizing the toilet seat heater when a human body is detected by the human body detecting means, and the energization amount When the value calculated by the calculation means is equal to or greater than the specified energization amount, the control means for reducing the energization amount to the hot water heater is provided.

  As a result, the energization amount to the hot water heater can be reduced without hindering the heating of the toilet seat, the amount of electric power as the toilet device can be suppressed, and the energy saving property can be improved and the usability can be improved.

  The toilet apparatus of the present invention includes a toilet seat having a toilet seat heater that warms immediately, such as a lamp heater that generates thermal energy in the cavity, a toilet lid that covers the surface of the toilet seat, and a toilet seat thermistor that detects the temperature in the vicinity of the toilet seat heater. And a toilet lid driving means for rotating the toilet lid, a human body detecting means for detecting the presence or absence of a human body, and when the human body is not detected by the human body detecting means, the toilet lid is closed by the toilet lid driving means. When the human body is detected by the human body detecting means, the toilet seat heater is energized. When the temperature detected by the toilet seat thermistor exceeds a specified temperature, the toilet lid driving means opens the toilet lid. It is provided with the control means to make.

  Thereby, when the toilet seat temperature rises, the toilet lid is closed by the toilet lid driving means, wasteful heat dissipation can be suppressed, and the surface temperature of the toilet seat can be quickly raised, so that the usability can be improved.

  The toilet device according to the present invention can provide a toilet device that has quick and warm performance and is easy to use and rich in energy saving.

  In particular, the fourth aspect of the invention adds a room heater for heating the toilet room space to the toilet apparatus of any one of the first to third aspects of the invention, and includes a toilet seat heater, a hot water heater, a drying heater, and a room heater. By determining the priority of energization amount and controlling the energization amount to each heater, energizing the toilet seat heater only when the human body is detected, the toilet seat is immediately warmed up and it is not cold when the human body is seated. Since the amount of electric power as a toilet device can be suppressed, for example, a leakage / overcurrent prevention circuit breaker or the like does not operate, and it is rich in energy saving and can improve usability.

  In particular, the fifth aspect of the invention relates to the toilet apparatus according to any one of the first to fourth aspects of the invention, comprising a toilet lid that covers the surface of the toilet seat, a toilet seat thermistor that detects the temperature in the vicinity of the toilet seat heater, and the toilet lid.

It is a thing.

  As a result, the control means controls the toilet lid drive means when the toilet seat temperature rises due to the energization of the toilet seat heater so that the toilet lid is in the closed state, so that wasteful heat radiation can be suppressed and the surface temperature of the toilet seat is quickly increased. Therefore, usability can be improved.

  In the sixth aspect of the invention, in particular, the toilet device of the fifth aspect of the present invention is further provided with a human body timing unit that starts timing after detecting a human body by the human body detection unit, and the time measured by the human body timing unit exceeds a specified value. In this case, the toilet lid is opened by the toilet lid drive means, and the control means controls the toilet lid drive means to close the toilet lid when the toilet seat temperature is increased by energization of the toilet seat heater. Therefore, useless heat dissipation can be suppressed and the toilet seat surface temperature can be quickly raised, so that the usability can be improved.

  In the seventh aspect of the invention, in particular, notification means for notifying when the detected temperature of the toilet seat thermistor when the toilet seat heater is energized exceeds a specified temperature is added to the toilet apparatus of the fifth or sixth aspect of the invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. Further, in the description of the present embodiment, the same reference numerals are given to the same configurations and the effects and the same description is not repeated.

(Embodiment 1)
FIG. 1 is a configuration diagram of a toilet apparatus according to the first embodiment of the present invention. In FIG. 1, a toilet seat 1 has a hollow portion (not shown) therein, and houses a lamp heater 2 for toilet seat heating as a toilet seat heater that warms up immediately when energized. The toilet seat 1 has the same transparent polypropylene resin seat 103 as the conventional toilet seat 102 shown in FIG. 10 and a radiant heat absorption layer 104 on the surface. The radiant heat from the lamp heater 2 is heated by the radiant heat absorption layer 104. The seating portion 103 is converted and heated quickly.

  The human body detection unit 3 detects a human body that has entered the toilet room and outputs a human body presence / absence signal to the control unit 4. The control means 4 is composed of a microcomputer and its peripheral circuits, takes in a signal for detecting a person who has entered the toilet room by the human body detection means 3 and energizes the lamp heater 2 and conducts the energization. During this time, the power supply to the hot water heater 5 is stopped.

  The hot water heater 5 is an electric heater or the like that heats washing water that ejects washing water from the local washing nozzle 6 to wash the human body part. A method generally known as the human body detection means 3 is an infrared ray emitted from a measurement distance formula that performs detection based on the presence or absence of reflected light from an object by irradiating infrared rays and the incident angle of the reflected light and the surface temperature of the human body. There is a pyroelectric type that detects the presence or absence of a human body from the difference between the amount and the amount of infrared rays emitted from an object (such as a wall surface of a toilet).

  In the case of the measurement distance type, it is not affected by the environmental temperature in the toilet room, but it measures the distance of the object from the human body detection means 3 based on its detection principle, and is the human body within the detection range? Whether it is an object cannot be determined. In addition, the pyroelectric method is not a method of irradiating infrared rays like the measurement distance method, so it has low power consumption, but the difference between the human body and the toilet wall surface is small when the ambient temperature is high and close to the human body surface temperature. , It is difficult to detect.

  In addition, as a method of heating the washing water for washing the human body part, a hot water storage type that has a hot water storage tank of about 1 L inside the toilet apparatus and a sheath heater of about 400 W is arranged in the hot water storage tank to heat the washing water, There is a known instantaneous formula in which an electric heater of about 1000 W is disposed in a flow path through which several tens of cc of water flows, and the water supplied from the water pipe is instantaneously heated in response to the user's instruction to start local body washing. Yes. In both cases, the washing water is heated, and the washing water is ejected to the local human body by the local washing nozzle 6.

  In the above embodiment, the lamp heater 2 in the toilet seat 1 is energized after receiving the human body presence signal from the human body detecting means 3 by the control means 4. The toilet seat 1 is heated to a temperature (for example, 35 ° C.) that the surface temperature of the toilet seat 1 does not feel cold when the user is seated after the lamp heater 2 is energized. Can warm up. Therefore, the temperature of the surface, which is the seating portion of the toilet seat 1, can be sufficiently warmed during the time from when the human body enters the toilet room to the toilet device and before the user takes off the clothes and sits down.

  Further, the lamp heater 2 has a filament resistance value of about several hundreds of ohms when it is energized stably, but it is as small as several tens of ohms when it is not energized. Will flow. However, the control means 4 does not energize the hot water heater 5 that heats the washing water for washing the local area of the human body until the lamp heater 2 is deenergized after receiving the human body presence signal from the human body detection means 3. Accordingly, when the hot water heater 5 is a hot water storage type, the wash water has already been stored inside the 1 L hot water storage tank, and when the hot water heater 5 is an instantaneous type, the hot water heater 5 is energized from the user's local cleaning start command. Therefore, it is possible to supply a sufficiently warm washing water when the washing water is ejected to the local body part.

  As described above, in the present embodiment, heating is performed immediately only when the toilet seat is used, and power consumption of the toilet apparatus is suppressed by stopping energization of the hot water heater. The circuit breaker or the like does not operate, is rich in energy saving, and can be improved in usability.

(Embodiment 2)
FIG. 2 is a configuration diagram of a toilet apparatus according to the second embodiment of the present invention. In the present embodiment, the energization amount calculation means for calculating the total from the energization amount to the lamp heater and the energization amount to the hot water heater, and the energization amount of the hot water heater when the calculated value of the energization amount calculation means exceeds the specified energization amount Unlike the invention of the first embodiment, the other configurations and operational effects are the same in that a control means for reducing the above is provided.

  That is, the energization amount calculation means 7 is formed integrally with the control means 4 and calculates the sum of the energization amount to the lamp heater 2 and the energization amount to the hot water heater 5. On the other hand, the control means 4a takes in a signal that the calculated value of the energization amount calculation means 7 is equal to or greater than a specified energization amount (for example, 1500 W), reduces the energization amount to the hot water heater 5, and uses the amount of power used as a toilet device. Is set to be equal to or less than the value of the specified energization amount.

  In the above embodiment, the energization amount calculation means 7 calculates the sum of the energization amount to the lamp heater 2 and the energization amount to the hot water heater 5, and the control means 4 incorporating the calculated value is the value of the specified energization amount. For example, if it is determined that the electric power is 1500 W or more, the energization amount to the hot water heater 5 is decreased so as to be 1500 W or less. Therefore, by suppressing the total power consumption of the toilet device to 1500 W or less, it is possible to prevent abnormal heating of power wiring in a general toilet room and malfunction of a leakage / overcurrent breaker.

  As described above, in the present embodiment, when the toilet seat is heated and used, if the total energization amount of the toilet seat heater and the hot water heater exceeds the specified energization amount, the energization amount to the hot water heater is reduced, Reduce power consumption. Therefore, when the toilet seat heater is energized, even if the power supplied to the hot water heater is reduced, it does not hinder the convenience of the toilet device and, for example, a leakage / overcurrent prevention circuit breaker operates. It is rich in energy saving and can improve usability.

(Embodiment 3)
FIG. 3 is a configuration diagram of a toilet apparatus according to the third embodiment of the present invention. In this embodiment, a drying heater that performs drying after washing a human body part and a room heating heater that heats the toilet room are added, and the priority order of the energization amount to these heaters is determined. Unlike the present invention, the other configurations and operational effects are the same.

  That is, it has the drying heater 8 which dries after washing a human body part, and the room heater 9 which heats the toilet room. The energization amount calculation means 7 is formed integrally with the control means 4 and calculates the sum of the energization amount to the lamp heater 2 and the energization amount to the hot water heater 5. On the other hand, the control unit 4b takes in a signal that the calculated value of the energization amount calculation unit 7 is equal to or greater than a specified energization amount (for example, 1500 W), reduces the energization amount to the hot water heater 5, and uses the amount of power used as a toilet device. Is set to be equal to or less than the value of the specified energization amount. Furthermore, the control means 4b predetermines the priority order of the energization amounts of the lamp heater 2, the hot water heater 5, the drying heater 8, and the room heater 9, and controls the energization amounts of the respective heaters to the details described below. That is, it is configured to control so that the overall energization amount is less than or equal to the specified energization amount.

  In the above embodiment, the toilet seat 1 is warmed by the lamp heater 2 and the washing water warmed by the hot water heater 5 is ejected from the local washing nozzle 6 to wash the local body part. And according to a user's warm air drying start instruction | indication, the drying heater 8 and the drying fan motor 10 are driven, and the warm air for drying is supplied to a human body local part. The drying heater 8 is stopped according to a user's warm air drying stop instruction, and the drying fan motor 10 is stopped after a certain time (for example, after 1 to 2 seconds), so that the drying heater 8 is sufficiently cooled to dry the drying wind tunnel. 11 is suppressing the temperature rise to the inside.

Further, the room heating heater 9 and the room heating fan motor 12 are driven by the user's room heating start instruction in the toilet room to warm the toilet room. Heating of the toilet room, such as at night in the winter, can be performed even when the human body is not entering the toilet room (timer operation), or a room temperature thermistor that detects the temperature in the toilet room (timer operation) (Not shown), an operation of automatically driving when the temperature becomes lower than a certain temperature (for example, 5 ° C., etc.) (toilet room cooling prevention operation) can be performed.

  When the room heater 9 is stopped, the room heater 9 is first stopped in the same manner as when the drying heater 8 is stopped, and the room heater fan motor 12 is stopped after a certain time (for example, 1-2 seconds). As a result, the room heater 9 is sufficiently cooled to suppress the temperature rise into the room heating wind tunnel 13.

  The drying heater 8 and the room heating heater 9 often use an electric heater of about 400 W, and, as in the case of the hot water heater 5, do not exceed a specified value (for example, 1500 W) of the total power amount as a toilet device. As described above, the energization amount of the drying heater 8 and the room heating heater 9 is reduced. The energization amount lowering order (priority order) of each heater at this time is expressed as a lamp heater 2, a drying heater 8, a hot water heater 5, and a room heating heater 9 in order not to decrease the energization amount, and this order is controlled. Means 4 holds. For example, when the lamp heater 2 is energized with 500 W, and the energization start command for the drying heater 8 is issued, the drying heater 8 (when the total power consumption is 400 W) energizes 400 W without reducing the energization amount. The hot water heater 5 (when the total power consumption is 500 W) is 500 W, the room heater 9 (when the total power consumption is 400 W) is 100 W, and the total power consumption of the toilet apparatus is suppressed to 1500 W.

  As described above, in the present embodiment, the toilet seat heater is immediately heated by energizing the toilet seat heater only when a human body is detected, and when the human body is seated, it is not cold, and the amount of power as a toilet device is suppressed. Therefore, for example, an earth leakage / overcurrent prevention circuit breaker or the like does not operate, and it is rich in energy saving and usability can be improved.

  In the present embodiment, all the power consumption of each heater is assigned in order from the highest priority heater to be energized, but this is a method of reducing the energization amount to each heater by 10% or the like. However, it goes without saying that the same operational effects as those of the present embodiment can be expected. Further, although the present embodiment has been described with the contents added to the invention of the second embodiment, it may be added to the invention of the first embodiment.

  In the present embodiment, the toilet apparatus includes both the drying heater 8 and the room heating heater 9, but the toilet apparatus may be a toilet apparatus having only the drying heater without the room heating heater.

(Embodiment 4)
FIG. 4A is a configuration diagram of a toilet apparatus according to a fourth embodiment of the present invention, and FIG. 4B is a perspective view showing the toilet seat in the toilet apparatus with the toilet lid closed. . This embodiment is characterized in that a toilet lid and a toilet lid driving means are added to the invention of the third embodiment. That is, the toilet lid 14 configured to cover the surface of the toilet seat 1, the toilet lid driving means 15 for rotating the toilet lid 14, and the temperature in the vicinity of the lamp heater 2 disposed inside the toilet seat 1 are detected. The toilet seat thermistor 16 is provided. The control means 4b closes the toilet lid 14 with the toilet lid driving means 15 when the human body detection means 3 does not detect the human body, and when the human body detection means 3 detects the human body, the control means 4b goes to the lamp heater 2. The toilet lid 14 is opened by the toilet lid driving means 15 when the temperature detected by the toilet seat thermistor 16 exceeds a specified temperature.

In the above-described embodiment, the control means 4b that takes in this signal controls the toilet lid driving means 15 until the human body detecting means 3 detects the human body but sits on the toilet seat. The toilet lid 14 is closed. When the toilet lid 14 is in the closed state, the gap between the toilet seat 1 and the toilet lid 14 is reduced, and heat dissipation from the surface of the toilet seat 1 is reduced. A human body is detected by the human body detection means 3, and the lamp heater 2 is first energized. When the lamp heater 2 is energized, the temperature is detected by the toilet seat thermistor 16 disposed in the vicinity of the lamp heater 2. . When the detected temperature of the toilet seat thermistor 16 becomes equal to or higher than the specified temperature, the control unit 4b controls the toilet lid driving unit 15 based on this signal to open the toilet lid 14.

  FIG. 5 shows a characteristic graph of the surface temperature of the toilet seat 1 by the lamp heater 2 when the toilet lid 14 is opened / closed. When the temperature detected by the toilet seat thermistor 16 reaches a specified temperature (for example, 40 ° C.), the temperature of the surface of the toilet seat 1 becomes a temperature (for example, 35 ° C.) that does not feel cold even when the human body is seated. When the toilet lid 14 is in the closed state, the clearance between the toilet seat 1 and the toilet lid 14 is reduced, so that heat radiation from the surface of the toilet seat 1 is reduced, and the temperature increase of the toilet seat 1 surface from the start of energization of the lamp heater 2 is accelerated. Further, when the toilet lid 14 is in an open state, heat radiation from the surface of the toilet seat 1 increases, and therefore, the temperature rise on the surface of the toilet seat 1 is delayed from the start of energization of the lamp heater 2.

  As described above, when the temperature detected by the toilet seat thermistor 16 is equal to or higher than the specified temperature, that is, when the surface temperature of the toilet seat 1 is equal to or higher than the specified temperature, the control means 4b controls the toilet lid driving means 15 to control the toilet lid 14. The user can be seated on the toilet seat 1 that has been warmed immediately. Therefore, even if a person sits on the toilet seat 1, it is not cold and easy to use.

  As described above, in the present embodiment, useless heat radiation from the toilet seat can be suppressed and the surface temperature of the toilet seat can be quickly raised, so that the usability can be improved.

(Embodiment 5)
FIG. 6 is a configuration diagram of the toilet apparatus according to the fifth embodiment of the present invention, and FIG. 6B is a perspective view showing the toilet seat in the toilet apparatus with the toilet lid closed. This embodiment is the same as that of the fourth embodiment (shown in FIGS. 4 (a) and 4 (b)), in the human body time measuring means that starts counting from the time when the human body detecting means is detected, and the toilet seat thermistor. A notification means for notifying that the detected temperature is equal to or higher than the specified temperature is added.

  That is, the control means 4b is provided with the human body timing means 17 and the notification means 18. The human body timing means 17 is formed integrally with or separately from the control means 4b, and starts measuring time when the human body detection means 3 detects that a human body is present. Further, the notification means 18 is controlled and notified by the control means 4b that has taken in a signal that the temperature detected by the toilet seat thermistor 16 is equal to or higher than the specified temperature.

  In the above embodiment, when the human body detecting means 3 detects the human body, the human body time measuring means 17 starts measuring time in response to the human body detection signal, and the control means 4b starts energizing the lamp heater 2. Since the toilet lid 14 is already in the closed state, the degree of increase in the surface temperature of the toilet seat 1 is less affected by the ambient temperature in the toilet room, and the time value of the human body time measuring means 17, that is, the lamp heater 2 is increased. The toilet lid 14 is rotated from the closed state to the opened state by the toilet lid driving means 15 controlled by the control means 4b in accordance with the energization time. Further, when the temperature detected by the toilet seat thermistor 16 becomes equal to or higher than a specified value, the control unit 4b causes the notification unit 18 to perform notification.

  As described above, according to the present embodiment, the surface temperature of the toilet seat becomes warm and the user can recognize when the toilet lid opens, so that the usability can be improved.

FIG. 7A is a configuration diagram of the toilet apparatus according to the sixth embodiment of the present invention, and FIG. 7B is a perspective view showing the toilet seat in the toilet apparatus with the toilet lid closed. . In this embodiment, the seating sensor and the function of reducing the amount of electricity supplied to the toilet seat heater when a human body is seated on the control means are added to the invention of Embodiment 5 (shown in FIGS. 6A and 6B). It is characterized by that.

  That is, the control means 4b has a seating sensor 19 that detects that a human body is seated on the toilet seat 1. Various systems have been used for the seating sensor 19 that is used in a toilet device and detects that a human body is seated on the toilet seat 1.

  To raise a few examples, a microswitch is arranged on a contact surface with a toilet (not shown) arranged on the lower surface of the toilet seat 1, a human body is seated on the toilet seat 1, and the microswitch is turned on by its weight, Similarly, there is a method (weight type) in which the weight of the human body is affixed with a conductive rubber on the rotating shaft of the toilet seat 1 and the conductive rubber is detected to be compressed. Similarly to the human body detection means 3 described above, a measurement distance type that detects the presence or absence of a human body with infrared reflected light by irradiating the human body with infrared rays, and further, a human body is attached to the toilet seat 1 by attaching a metal plate. There is a capacitance type that detects that the stray capacitance component between the metal plate and the ground changes due to sitting.

  When receiving a signal from the seating sensor 19 that the human body is seated on the toilet seat 1, the control means 4 b is configured to reduce the energization amount to the lamp heater 2 with the details described below.

  In the above embodiment, the seating sensor 19 detects that the human body is seated on the toilet seat 1, and the timekeeping means 19 starts timing from this point. In general, when a human body is in contact with an object, the object is relatively low temperature, but a low temperature burn phenomenon occurs if the object is in contact with the same part for a long time.

  However, in the present embodiment, as shown in FIG. 8A, a method of reducing the energization amount of the lamp heater 2 to a certain amount (for example, 50%) after the human body is seated, or FIG. As shown, according to the seating sensor 19, the energization amount is not decreased for a certain period of time (for example, 2 minutes) after sitting, and the energization amount is measured for a certain period of time (3 minutes between 2 and 5 minutes). Is decreased in proportion to the measured value of time (for example, gradually decreased from 100% to 40%), and after that, the energization amount is maintained while being decreased (for example, 40%), and thereafter the lamp heater 2 is maintained. The method of stopping the energization is used. Therefore, the user can sit safely without worrying about low temperature burns.

  Although the control means 4b in the above embodiment performs the energization control to the lamp heater 2 having the above-described contents, it may have a control configuration as shown in FIG. That is, since the detection temperature of the toilet seat thermistor 16 disposed in the vicinity of the lamp heater 2 changes when the human body is seated, if the change amount of the detection temperature is large, the heat capacity of the human body is large, that is, a relatively large size. Since it is a person, the control means 4b decreases the energization amount to the lamp heater 2 more greatly (for example, further increases the decrease amount by 20% to the decrease of the energization amount).

  In addition, when the amount of change in the detected temperature of the toilet seat thermistor 16 is small, the human body has a small heat capacity and the small person and the control means 4b judge and reduce the amount of decrease in the energization amount. Of course, even if the method of reducing the energization amount of the lamp heater 2 is another method in which the time and the amount of decrease are changed, it is possible to have the same operational effects as the present embodiment.

  Moreover, the said embodiment can be implemented also in each invention of the said Embodiment 1, Embodiment 2, and Embodiment 3, and can anticipate the effect similar to this Embodiment.

As described above, the toilet device according to the present invention supplies the toilet seat heater disposed on the toilet seat when a human body is detected, and performs power control for a time corresponding to the environmental temperature, thereby improving the safety of the heating device. It can also be applied to other heating equipment that requires safety and energy saving, such as ensuring heating and controlling heating output frequently depending on the presence or absence of a human body.
