Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated toilet seat device for heating the surface of a toilet seat.

[Prior art]

Conventionally, a toilet seat heating means 12z which is heated by applying a voltage such as a tube heater or a sheet heater is provided inside the toilet seat 2z having a hollow structure shown in FIG. The main body case 5z is provided with a control section 9z for controlling the amount of heat generated by the heating means 12 to uniformly heat the entire upper surface of the toilet seat 2z to a set temperature according to the user's preference. The heating toilet seat device 1z that heats up by heating is widely used. FIG. 10 shows the temperature distribution of the surface (heating area) of the toilet seat 2z heated by the toilet seat heating means 12z. The direction toward the back of the toilet seat here refers to the direction behind the user when the user sits on the toilet seat, and the direction toward the toilet seat refers to the direction front of the user when the user sits on the toilet seat. By installing the heating toilet seat device 1z in the toilet and preheating the entire upper surface of the toilet seat 2z,
Toilet seat 2 where the user is always warm, even when the temperature is low such as in winter
You can sit on z and have a comfortable bowel movement.

[0003]

Usually, a heating toilet seat device 1 is used.
When the toilet room temperature is as low as around 5 ° C., if the upper surface of the toilet seat 2 z is uniformly warmed up to around 40 ° C. and the temperature is kept at around 40 ° C., the toilet seat heating means 12 z constantly consumes about 50 to 100 W of power. Due to the recent energy saving circumstances, it is desired to reduce the power consumption of the heating toilet seat device 1z as well. However, simply trying to reduce or reduce power consumption makes it impossible to raise the temperature of the toilet seat surface to a set temperature such as in the winter when the room temperature is low, so when the user sits on the toilet seat, it is difficult to obtain a feeling of heating. It becomes impossible to defecate comfortably.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a heated toilet seat device which can provide a user with a feeling of heating and can reduce power consumption.

[0005]

In order to solve the above-mentioned problems, the invention according to claim 1 is a heating toilet seat device for heating the surface of a toilet seat, which is provided for excretion in the substantially central portion of the toilet seat. With the center point of the opening as a reference, the tangent line of the end face portion in the longitudinal direction and the depth direction of the opening is the boundary line 1, and the center line passing through the center point in parallel with the boundary line 1 is the boundary line 2. The boundary line 3 is the tangent line of the end facet in the longitudinal direction and the forward direction of the opening, and the toilet seat surface sandwiched between the boundary line 1 and the boundary line 2 is the heating area 1, the boundary line 2 and the boundary line 2. The toilet seat surface sandwiched between the boundary lines 3 is a heating area 2, the toilet seat surface from the boundary line 2 to the tip of the toilet seat is a heating area 3, and the toilet seat surface from the toilet seat rear end to the boundary line 1 is a heating area. When set to 4, the heating area 1 and the heating area The average temperature of the toilet seat surface in the heating region 3 is a heating toilet seat and wherein the higher than the average temperature of the toilet seat surface in the heating region 4. Here, the longitudinal direction refers to the direction parallel to the direction of the thigh when the user sits on the toilet seat, and the back direction refers to the direction behind the user when the user sits on the toilet seat. ,
The forward direction refers to the direction in which the user is in front of the user when sitting on the toilet seat. Further, the outermost end surface of the opening is usually provided with a taper around the opening to improve the sitting comfort when the opening is viewed from the toilet seat surface side on which the user sits. It may be considered as a part and the boundary part between the smooth part and the tapered part of the toilet seat surface may be the most end surface, or the end of the opening viewed from the back surface of the toilet seat (toilet seat surface facing the toilet bowl) may be simply the most end surface. . The average temperature refers to the average temperature of the toilet seat surface in each heating area when the toilet seat heating means is controlled to reach each target temperature in each heating area,
This can be easily grasped by measuring the total surface temperature of each heated toilet seat area using an infrared thermal imager such as thermography and dividing this total surface temperature by the total surface area of the heating area of the heating area. When the user sits on the toilet seat and the toilet seats of heating area 1, heating area 2 and heating area 3 where the backsides of the buttocks and thighs contact each other, the entire upper surface of the toilet seat is heated evenly. Even if you do not have it, you can comfortably defecate without feeling cold. For example, even if the heating area 1, the heating area 2, and the heating area 3 are warmed up to around 40 ° C. and the heating area 4 is heated to around 35 ° C.,
A sufficient heating feeling can be obtained when the user sits down. As described above, by sufficiently warming only the area where the user sits on the toilet seat, power consumption can be reduced and economy can be improved rather than uniformly heating the entire upper surface of the toilet seat. As a method of giving a predetermined temperature gradient to the temperature distribution on the surface of the toilet seat, heating is performed by arranging a sheet heating element having a different calorific value at each location in advance inside the toilet seat formed in a hollow structure and heating the tube heater. Various forms are conceivable, such as arranging and heating, or heating by blowing warm air from the toilet lid to the surface of the toilet seat.

The invention according to claim 2 is characterized in that the average temperature of the toilet seat surface in the heating area 1 and the heating area 2 is higher than the average temperature of the toilet seat surface in the heating area 3. It is a heating toilet seat device. When the user sits on the toilet seat, seat pressure is applied to the heating area 1 and the heating area 2, and almost no seat pressure is applied to the heating area 3, and the seat area is lightly contacted. Therefore, when the user sits on the toilet seat, if the surface of the toilet seat is warmed around the heating area 1 and the heating area 2 to which seat pressure is applied, almost no seat pressure will be applied and the thighs will be in slight contact. Even if the temperature of the heating area 3 is slightly low, a feeling of cooling is not felt, a sufficient feeling of heating is obtained, defecation can be comfortably performed, and further power saving can be achieved, thus improving the economical efficiency.

The invention according to claim 3 is characterized in that the average temperature of the toilet seat surface in the heating area 2 is higher than the average temperature of the toilet seat surface in the heating area 1.
The heating toilet seat device according to claim 1. The skin surface temperatures of the buttocks and thighs differ depending on the body shape and age of the user and the ambient temperature, but the thighs have a temperature higher by 2 to 3 ° C. than the buttocks. Therefore, when the user sits on the toilet seat where the temperatures of the toilet seat surfaces in the heating area 1 and the heating area 2 are uniform, the toilet seat surface temperature felt by the thighs is lower than the toilet seat surface temperature felt by the buttocks. Therefore, by heating the heating area 2 in contact with the thighs more than the heating area 1, the user can obtain a uniform heating feeling. Therefore, by warming the surface of the toilet seat in accordance with the surface temperature distribution of the human skin that comes into contact with the toilet seat when sitting, it is possible to further save power and improve economy.

According to a fourth aspect of the present invention, the toilet seat heating means is controlled so that the average temperature of the heating area 2 becomes a set temperature set by the user. It is the heating toilet seat device described. When the user sets the toilet seat temperature, since the temperature of the toilet seat surface differs for each heating area, the temperature may be set for each heating area, but the operation is complicated and troublesome. In addition, it is difficult to control a wide heating area with a horseshoe shape like a toilet seat with a single temperature detection element, so it is designed so that a specific location on the toilet seat has the highest temperature, and the temperature detection is performed at the highest temperature location. If you arrange the elements,
Since the maximum temperature of the toilet seat is constantly detected, safety that does not lead to burns or fire can be maintained. Therefore, when the operation is simplified and the user sets the temperature with one operation, a reference temperature is required. At that time, since the heating area 2 has the highest temperature due to the seat pressure distribution of the toilet seat and the surface temperature distribution of the human body skin, the toilet seat heating means is controlled so that the average temperature of the heating area 2 becomes the set temperature set by the user. By doing so, the safety is improved and the user can sit in comfort.

According to a fifth aspect of the present invention, a blower fan for blowing air, and a warm air heater arranged in the duct for heating the air blown by the blower fan to generate warm air are provided.
A control unit that controls the number of revolutions of the blower fan and the amount of heat generated by the warm air heater, a main body case that houses the blower fan, the warm air heater, and the control unit, and the main body case is disposed on the front side surface of the main body case. An outlet communicating with the duct, and a toilet seat arranged in front of the main body case,
In a heating toilet seat device that blows warm air from the outlet to warm the surface of the toilet seat, the temperature or volume of the warm air blown from the outlet to each heating area is controlled. The heating toilet seat device according to any one of 4 above. If a toilet seat heating means such as a tube heater is placed inside the toilet seat and the surface temperature of the toilet seat is to be changed for each heating area, a plurality of heating means and electric wiring are required, resulting in a complicated structure and reduced productivity. . When warming the toilet seat surface by blowing warm air directly from the outlet to the toilet seat surface,
The temperature of the toilet seat surface is determined by the air temperature (the temperature of the hot air) and the air flow (the air flow of the hot air). Therefore, by controlling the air temperature and the amount of air blown to the toilet seat surface for each heating area, the temperature of the toilet seat surface can be easily changed for each heating area without complicating the toilet seat structure.

According to a sixth aspect of the present invention, there is provided the heating toilet seat device according to the fifth aspect, characterized in that a plate-shaped wind direction indicator plate is arranged so as to extend over the opposing surfaces of the outlet. A plurality of ventilation paths are formed by arranging a plate-shaped wind direction indicator plate that is hung on the opposite surfaces of the outlet.
It is possible to change the wind direction of the warm air blown from each ventilation passage, and by changing the interval and angle of the wind direction indicator, it is possible to change the amount of warm air blown from each ventilation passage. . Therefore, by arranging the plate-shaped wind direction indicator plates that are laid over the opposite surfaces of the air outlet, the hot air can be blown in a wide range and the air volume can be varied even if the air outlet does not move. Therefore, the temperature distribution on the toilet seat surface can be easily changed without changing the rotation speed of the blower fan and the heat generation amount of the warm air heater. By arranging a plurality of wind direction indicator plates in parallel to the toilet seat surface, it is possible to change the air volume in the toilet seat longitudinal direction from the back end to the tip of the toilet seat. As a result, the air volume in the width direction of the toilet seat can be changed, and therefore the airflow volume can be arranged according to the size of the heating area. Further, the wind direction indicator plate may be fixed to the outlet, but by moving it, the waist and thigh exposed to the outside air can be efficiently warmed when the user sits down.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a heating toilet seat device according to the present invention will be described in detail below with reference to the drawings. (First Embodiment) FIG. 1 is a top view showing a first embodiment of a heating toilet seat device 1a of the present invention, FIG. 2 is a schematic configuration diagram of a heater of the device, and FIGS. 3 to 5 are views of the surface of a toilet seat 2a of the device. It is a graph which shows the temperature distribution in a longitudinal direction. The heating toilet seat device 1a shown in FIG. 1 has an opening 3 with reference to a center point 4a of an opening 3a provided for excretion in a substantially central portion of the toilet seat 2a.
The tangent line of the end face portion in the longitudinal direction and the depth direction of a is the boundary line 1, the center line passing through the center point 4a in parallel with the boundary line 1 is the boundary line 2, the longitudinal direction of the opening 3a, and the forward direction. The tangent line of the most end face is the boundary line 3, the surface of the toilet seat 2a sandwiched between the boundary lines 1 and 2 is the heating area 1, the surface of the toilet seat 2a sandwiched between the boundary lines 2 and 3 is the heating area 2, the boundary. Line 2 to toilet seat 2
The surface of the toilet seat 2a up to the tip of a is divided into a heating area 3 and the surface of the toilet seat 2a from the back end of the toilet seat 2a to the boundary line 1 is divided into a heating area 4. Then, the toilet seat heating means 12a, 12b, 12c, 12d made of sheet heating elements are arranged inside the toilet seat 2a for each heating area, and the toilet seat heating means 12a to 12d are provided.
Are connected in parallel. The voltage applied from the controller 9b is V, and the resistance values of the toilet seat heating means 12a to 12d are R1.
Assuming that the power consumption W1 in the heating area 1 is W1 = V × V / R1, the power consumption W2 in the heating area 2 is W2 = V × V / R2, and the power consumption W3 in the heating area 3 is W3 = V × V / R3 The power consumption W4 in the heating area 4 is W4 = V × V / R4, and the heat amounts Q1 to Q corresponding to the respective power consumptions W1 to W2.
Heat is transferred from the toilet seat heating means to the surface of the toilet seat 2a, so that the surface of the toilet seat 2a can be heated. Therefore, when the surface area of each heating area and the heat transfer coefficient from the inner surface of the toilet seat to the outer surface of the toilet seat are equal, the average temperature in each heating area can be changed by changing the resistance value of each toilet seat heating means. However, since the surface area in each heating area is different in reality, the average temperature differs depending on the surface area in each heating area even if the heat amounts Q1 to Q4 are the same. Therefore, the surface area of the heating area 1 on the toilet seat surface is S1,
The surface area of the heating area 2 is S2, and the surface area of the heating area 3 is S
3, and the surface area of the heating area 4 is S4, the power density P1 in the heating area 1 is P1 = W1 / S1 The power density P2 in the heating area 2 is P2 = W2 / S2 The power density P3 in the heating area 3 is P3 = W3 / S3 The power density P4 in the heating area 4 is P4 = W4 / S4, and in order to change the average temperature in each heating area, the surface areas S1 to S4 are changed so that the power densities P1 to P4 are different.
According to the resistance value R1 of each of the toilet seat heating means 12a to 12d.
It is sufficient to set up to R4. When the user of the toilet seat sets the temperature of the toilet seat surface, the user shall set the average temperature of the heating area where the average temperature is the highest, and the thermistor installed in the heating area where the average temperature is the highest. If the energization control is performed so that the temperature detected by the above becomes the set temperature, the resistance values R1 to R4 may be set so as to be equal to or lower than the set temperature set in the other heating areas.

(First embodiment) Power density P1 = Power density P
Even if energization control is performed by one controller 9b by setting the resistance values R1 to R4 of the toilet seat heating means 12a to 12d so that 2 = power density P3> power density P4, for example, as shown in FIG. The average temperature of the heating area 1, the heating area 2, and the heating area 3 can be set to 40 ° C., and the average temperature of the heating area 4 can be set to 38 ° C. Further, the toilet seat heating means 12 arranged on the inner surface of the toilet seat 2a corresponding to the heating area 4
d is connected to a control unit (not shown) different from the control unit 9b for controlling the toilet seat heating units 12a to 12c by a wiring independent of the other toilet seat heating units 12a to 12c to control energization. By doing so, it is possible to freely change the average temperature without affecting other heating areas. In this case, when the user sits on the toilet seat, the heating area 1 where the buttocks are in contact with the heating area 2 where the thighs are in contact, The heating region 4 is heated to a set temperature (usually around 30 to 40 ° C.) set by the user, and the heating region 4 in which the buttocks hardly come into contact with the heating region 3 has a fixed temperature lower than the set temperature set by the user ( If you warm it up to the extent that it does not get cold according to the temperature inside the toilet, for example, around 25 ° C, even if the entire upper surface of the toilet seat is not evenly heated,
You can get a good feeling of heating without feeling cold, and you can defecate comfortably. Therefore, by sufficiently warming only the area where the user sits on the toilet seat, the power consumption can be reduced and the economy can be improved as compared with the case where the entire upper surface of the toilet seat is warmed. By providing a certain temperature gradient in each heating area instead of changing the temperature suddenly in the vicinity of the boundary where each heating area is adjacent, the temperature distribution can be provided without giving the user a feeling of discomfort. At this time,
The surface temperature is partially lower or higher than the average temperature in each heating area, but if the variation in the temperature distribution in each heating area is too large, even if the average temperature is sufficiently high, it will cool when the user sits down. It is preferable that the temperature distribution variation in each heating region is within 5 ° C., because it is not possible to feel or feel a uniform heating sensation. Although not shown in the graph, the heating area 1, the heating area 2, the heating area 2 and the heating area are used irrespective of the set temperature when the temperature inside the toilet is cold, such as 5 ° C. or less, or at times when the user rarely uses the toilet. It is possible to warm the area 3 to around 25 ° C. and the heating area 4 to around 20 ° C. Even in this case, even if the user goes to the toilet and sits on the toilet seat, it is difficult to obtain a feeling of heating, but the user can defecate without feeling a feeling of cooling.

(Second Embodiment) Power Density P1 = Power Density P
Even if energization control is performed by one controller 9b by setting the resistance values R1 to R4 of the toilet seat heating means 12a to 12d so that 2> power density P3> power density P4, for example, FIG. The average temperature of the heating area 1 and the heating area 2 is 40 ° C, and the average temperature of the heating area 3 is 3
The average temperature of the heating region 4 can be set to 8 ° C. and 30 ° C. As described above, when the user sits on the toilet seat 2a, if the surface of the toilet seat 2a is warmed around the heating area 1 and the heating area 2 to which seat pressure is applied, almost no seat pressure is applied, and the thigh portion is lightly contacted. Even if the surface temperature of the heating area 3 is slightly low,
You can get a good feeling of heating without feeling cold, and you can defecate comfortably. However, if the temperature difference between the heating area 2 and the heating area 3 is too large, the user feels cold when sitting down, so that the temperature difference may be changed according to the toilet room temperature or the set temperature. The toilet seat heating means 12c arranged on the inner surface of the toilet seat 2a corresponding to the heating area 3 is replaced with the toilet seat heating means 12a to 12 for the heating areas 1 and 2 and the heating area 4.
Wiring independent of b and 12d is used as the toilet seat heating means 1
2a to 12b are controlled by a control unit 9b, a toilet seat heating unit 12c is controlled by a control unit (not shown), and a toilet seat heating unit 12d is controlled by a control unit (not shown). Only 12a to 12b are energized and controlled according to the set temperature set according to the user's preference based on a signal from a thermistor (not shown) that detects the room temperature, so that the temperature is not affected in other heating areas. The difference can be changed freely. Specifically, the toilet seat heating means 12d is 25 ° C.
So that the heating area 1 = heating area 2
When the set temperature of 40 ℃ is, the average temperature of the heating area 3 is 35
The toilet seat heating means 12c is controlled so that the temperature becomes ℃, and the heating area 1
= When the set temperature of the heating area 2 is 30 ° C, the toilet seat heating means 12c is controlled so that the average temperature of the heating area 3 becomes 28 ° C. The temperature difference from the region 3 may be reduced. As described above, by lowering the average temperature of the heating area 3 than that of the heating areas 1 and 2, it is possible to further save power and improve the economical efficiency.

(Third embodiment) Power density P2> Power density P
By setting the resistance values R1 to R4 of the toilet seat heating means 12a to 12d so that 1> power density P3> power density P4, for example, the average temperature of the heating area 1 as shown in FIG. , The average temperature of the heating area 2 is 40 ° C., the average temperature of the heating area 3 is 35 ° C., the average temperature of the heating area 4 is 3
It can be 0 ° C. The surface temperature of the skin in the buttocks and the thighs varies depending on the body shape and age of the user and the ambient temperature, but the thighs are higher by about 1 to 5 ° C. than the buttocks.
Therefore, when the user sits on the toilet seat where the temperatures of the toilet seat surfaces in the heating area 1 and the heating area 2 are uniform, the toilet seat surface temperature felt by the thighs is lower than the toilet seat surface temperature felt by the buttocks. Therefore, by heating the heating area 2 in contact with the thighs to be warmer than the heating area 1, the user can obtain a uniform heating feeling, can comfortably defecate, and can further save electricity and improve economic efficiency. To do. Also, because the local position is different between men and women, men tend to spread their thighs,
Since a woman tends to sit in the direction in which both thighs are attached, it is preferable that the temperatures of the heating area 1 and the heating area 3 are approximately the same for a woman, and the heating area 1 and the heating area 3 are for a man.
It is preferable to raise the temperature.

(Second Embodiment) FIG. 6 is a top view showing a second embodiment of the heating toilet seat device 1b of the present invention, FIG. 7 is a side view of the same device, and FIG. 8 is a graph showing the temperature distribution in the longitudinal direction of the toilet seat surface of the same device. The heating toilet seat device 1b shown in FIG. 6 includes blower fans 6a and 6b for blowing air, ducts 7a and 7b for passing the air blown by the blower fans 6a and 6b, and a duct 7.
The main body case includes warm air heaters 8a and 8b that are placed in a and 7b to heat the air to be blown to make warm air, and a control unit 9a that controls the rotation speed of the blower fan 6 and the heat generation amount of the warm air heater 8. 5b, outlets 10a, 10b communicating with the ducts 7a, 7b are fixed to both ends of the front side surface of the main body case 5b, and a toilet seat 2b is arranged in front of them. When warm air is blown directly from the outlets 10a and 10b to the surface of the toilet seat 2b to warm the surface of the toilet seat 2b, the temperature of the toilet seat 2b surface is determined by the air temperature (the temperature of the warm air) and the air volume (the amount of the warm air that is blown). To do. Therefore, the temperature of the toilet seat surface can be easily changed for each heating area by controlling the air temperature and the amount of air blown to the surface of the toilet seat 2b for each heating area. In this embodiment, as in the first embodiment, the heating area of the toilet seat 2b is divided, and a predetermined voltage is applied to the blower fans 6a and 6b and the warm air heaters 8a and 8b to blow the air from the outlets 10a and 10b. When the warm air is blown to the heating area, the heat quantity blown to the heating area 1 is Q1, the heat quantity blown to the heating area 2 is Q2, the heat quantity blown to the heating area 3 is Q3, and the heat quantity blown to the heating area 4 is Q4. , S1 is the surface area of the heating area 1, S2 is the surface area of the heating area 2, S3 is the surface area of the heating area 3, and S4 is the surface area of the heating area 4, (Q2 / S2)> (Q1 / S
1)> (Q3 / S3)> (Q4 / S4) so that a plurality of wind direction indicator plates 11a, 1 are provided at the outlets 10a, 10b.
1b, 11c, 11d, and 11e are arranged at predetermined intervals and angles to fix the air volume ratio. As a result, as shown in FIG. 8, the temperature distribution on the surface of the toilet seat 2b becomes 3
The average temperature can be changed for each heating region, such as 8 ° C., the heating region 2 is 40 ° C., the heating region 3 is 37 ° C., and the heating region 4 is 35 ° C.

As described above, the average temperature of the toilet seat surface is set to heating area 2> heating area 1> heating area 3> heating area 4 according to the seat pressure distribution of the user and the temperature distribution of the skin surface. When seated on toilet seat 2b, toilet seat 2
Even if the entire upper surface of b is not evenly heated, a feeling of cooling is not felt and a sufficient feeling of heating is obtained, and defecation can be comfortably performed. Therefore, it is possible to reduce power consumption rather than heating the entire upper surface of the toilet seat, which improves economic efficiency.

The cross-sectional shape of the outlet is rectangular or circular,
An oval shape and a shape that can uniformly blow air without obstructing the flow of the air are preferable, and the location of the outlet on the front side of the main body is also the central part of the front side of the main case when the outlet is electrically movable vertically and horizontally. In the case of a blowout port that is electrically movable up and down, a plurality of blowout ports are placed at both ends and in the center of the front side surface of the main body case. Various forms are conceivable depending on the shape of the outlet and the movable mechanism such as a plurality of arrangements. For example, when using an outlet that can be electrically driven up, down, left and right and blows warm air to each heating area, the rotation speed of the blower fan is always controlled to be constant (air volume is constant) regardless of the blowing direction. The heat value of the hot air heater is variably controlled to change the temperature of the air blown for each heating area. The heat value of the warm air heater is always constant (air temperature is constant) regardless of the blowing direction.
Control to variably control the rotation speed of the blower fan to change the amount of air blown for each heating area, and to variably control the rotation speed of the blower fan and the heat generation amount of the warm air heater at the same time according to the blowing direction. The temperature of the toilet seat surface can be set to the average temperature of each heating area. Further, when a plurality of outlets are arranged, the warm air heater and the drying fan are also used so that the apparatus can be made compact and the productivity is improved.

By arranging a plurality of airflow direction indicator plates 11 on the inner surface of the air outlet 10, a plurality of airflow passages are formed, and the airflow direction of warm air blown from each airflow passage can be changed. By changing the interval and angle of the indicator plates, it is possible to change the amount of warm air blown from each ventilation passage. Therefore, by arranging a plurality of wind direction indicator plates on the inner surface of the blow-out port, it is possible to blow warm air over a wide range and to change the amount of the blown air even if the blow-out port does not move. It is possible to easily change the temperature distribution on the surface of the toilet seat without changing the rotation speed and the heat generation amount of the warm air heater. Further, since the air volume ratio of the warm air blown to each heating area is fixed, the heating temperature can be easily changed by variably controlling the rotation speed of the blower fan and the heat generation amount of the warm air heater by the control unit. You can Since the air volume ratio is fixed, the toilet seat heating means is controlled so that the average temperature of the heating area 2 becomes the set temperature set by the user, so that the heating area 1 other than this heating area 2 is inevitably generated. , 3 and 4 are lower than the average temperature of the heating area 2, the safety is improved and the user can sit down with peace of mind.
