(first embodiment)

Fig. 1 is a perspective view of an example of a pet temperature regulating device according to the present embodiment. Fig. 2 is a cross-sectional view viewed along line II-II in Fig. 1 .

As shown in FIG. 1 and FIG. 2 , the temperature regulating device 100 for pets has a foundation 1 , a heat conductor 2 , and a box body 3 . The foundation 1 supports the heat conductor 2 and the box body 3 .

The heat conductor 2 has a first end portion 2a and a second end portion 2b. On the side of the first end portion 2a of the heat conductor 2, a sheet-shaped sheet portion 2c on which pets such as cats and dogs ride and sleep or rest is provided. This sheet portion 2c is exposed from the box body 3 . Also, on the side of the second end portion 2b of the heat conductor 2, it becomes The shaped part 2c is bent and raised in an L-shape, and the raised part is provided with a mounting part 2d for mounting a Peltier element (cooling mechanism) 4, a heat sink 5 (radiating mechanism) and the like.

The box 3 is a rounded cuboid, partially covers the foundation 1 and the heat transfer body 2 , and accommodates the mounting portion 2 d of the heat transfer body 2 , the Peltier element 4 , the radiator 5 , and the fan 6 .

The Peltier element 4 is a thermoelectric conversion element for cooling at least the heat conductor 2 , and is attached so as to be in contact with the back side of the mounting portion 2 d of the heat conductor 2 . The Peltier element 4 cools the heat conductor by applying a temperature difference between the heat conductor 2 and the heat sink 5 which is a heat dissipation mechanism, for example. In addition, in order to conduct the heat of the Peltier element 4 to the sheet-shaped part 2c, the heat conductor 2 is preferably formed from a plate made of a thermally conductive material such as aluminum, copper, steel, stainless steel, etc., considering thermal conductivity and processability. , cost, etc., more preferably include an aluminum sheet comprising an aluminum plate. The temperature of the sheet portion 2c is adjusted by the heat transmitted from the Peltier element 4, thereby providing a comfortable temperature environment for the pet. In addition, the Peltier element 4 changes the direction and intensity of the current, whereby cooling and heating can be regulated. In addition, the shape of the mounting portion 2d of the heat conductor 2 is preferably adapted to the size of the Peltier element 4, the heat sink 5, and the like, for example.

The heat sink 5 is a radiator for dissipating heat from the Peltier element 4 , and is provided so as to be in contact with the Peltier element 4 . The heat sink 5 has a rectangular plate-like portion 5 a and a plurality of fins 5 b extending vertically from the plate-like portion 5 a and arranged substantially parallel to the long sides of the plate-like portion 5 a. The plate portion 5 a of the heat sink 5 is in contact with the Peltier element 4 . Moreover, the fan 6 is provided so that it may oppose the fin 5b of the heat sink 5, and it blows air to the heat sink 5, and it becomes an air-cooling system. In addition, in this embodiment, although the fins 5b are arranged substantially parallel to the long side of the plate-shaped part 5a in the heat sink 5, it is illustrated as an example, but it is not limited to this, and may be arranged substantially parallel to the short side, for example. composition. In this heat sink 5, a second thermistor (second temperature detection mechanism) 11 that detects the temperature in the vicinity of the Peltier element 4 is provided. The second thermistor 11 is used, for example, to prevent the Peltier element 4 from being damaged due to high temperature. For example, when the second thermistor 11 detects a predetermined temperature, for example, 80° C. or higher, the energization to the Peltier element 4 is stopped to prevent damage to the Peltier element 4 . As mentioned above, in this embodiment, although the second thermistor 11 is provided on the heat sink 5, it is not limited to this form, and it is not particularly limited to this as long as it can detect the temperature near the Peltier element 4. Composition, setting position.

Further, between the sheet portion 2c of the heat conductor 2 and the foundation 1, a heat insulating member 7, a heater (heating mechanism) 8, and an insulating sheet 9 are sequentially stacked from the foundation 1 side and supported by the foundation 1. The heater 8 is for heating the sheet portion 2c. Thus, for example, it is preferable to heat the sheet-like portion 2c only with the heater 8 without operating the Peltier element 4 . As the heater 8, a sheet-shaped aluminum heater etc. are mentioned, for example. The heat insulating member 7 suppresses the diffusion of heat to the bottom surface side of the foundation 1 and is formed of, for example, polystyrene foam. The insulating sheet 9 insulates the sheet portion 2c from the heater 8 and is formed of insulating resin or the like. Moreover, in the lower part of the sheet part 2c, the 1st thermistor (1st temperature detection means) 10 which detects the temperature of the sheet part 2c is provided.

In addition, in the temperature regulating device 100 for pets, it is possible to switch between a cooling mode in which the sheet portion 2c is cooled by the Peltier element 4 and a heating mode in which the sheet portion 2c is heated to a set temperature by the heater 8 . The set temperature of this heating mode is, for example, can be preset in the temperature regulating device for pets, or can be set by the user. If it is a temperature that does not cause discomfort such as scalding to pets, it is not special. limited.

FIG. 3 is a diagram showing an example of the temperature regulating device 100 for pets. The pet temperature regulating device 100 associated with this embodiment has, for example, a control unit 101, a memory unit 102, a timer unit 103, a Peltier element 4, a heater 8, a first thermistor (the first temperature detection mechanism) 10. The second thermistor (second temperature detection mechanism) 11. The control unit 101 is, for example, a CPU, an MPU, or the like, and executes various information processing according to programs stored in the memory unit 102 . The storage unit 102 is, for example, a flash memory, RAM, etc., and stores programs executed by the control unit 101 and various data. In addition, the storage unit 102 also functions as a working memory of the control unit 101 . Also, the timer unit 103 measures time. again, The control unit is connected to each of the Peltier element 4, the heater 8, the first thermistor 10, the second thermistor 11, and the like, and controls each part.

FIG. 4 is a diagram showing an example of the functional configuration of the control unit 101 of the pet temperature regulating device 100 shown in FIG. 3 . As shown in FIG. 4 , the control unit 101 of the pet temperature regulating device 100 of this embodiment functionally includes an initial first temperature acquisition unit 201 , an initial second temperature acquisition unit 202 , and a temperature adjustment unit 203 . In addition, in this embodiment, a case will be described in which the temperature adjustment device 100 for pets is powered on and the temperature of the sheet portion 2c is adjusted when the user instructs it to operate in the heating mode.

The initial first temperature acquiring unit 201 acquires the initial first temperature T1 which is the temperature of the sheet portion 2 c detected by the first thermistor 10 when the pet temperature regulating device 100 is powered on.

The initial second temperature acquiring unit 202 acquires the initial second temperature T2 which is the temperature of the radiator 5 detected by the second thermistor 11 when the pet temperature regulating device 100 is powered on.

The temperature adjustment unit 203 controls the Peltier element 4 or the heater 8 based on the initial first temperature T1 and the initial second temperature T2 to adjust the temperature of the sheet portion 2c. For example, in the heating mode, the temperature adjustment part 203 adjusts so that the temperature of the sheet part 2c detected by the 1st thermistor 10 becomes a set temperature (for example, 38 degreeC).

Specifically, as shown in FIG. 5 , the temperature adjustment unit 203 functionally includes a previous operation determination unit 301, an outside air temperature prediction unit 302, an initial energization level information acquisition unit 303, a set temperature adjustment temperature acquisition unit 304, a set temperature The energization level information acquisition unit 305 for adjustment and the operation control unit 306 .

The operation control unit 306 controls the operations of the heater 8 and the Peltier element 4 . The operation control unit 306 controls the conduction rate in the heater 8 and the Peltier element 4, thereby adjusting the temperature of the chip portion 2c. In this embodiment, for example, after the power is turned on, until the temperature detected by the first thermistor becomes close to the set temperature (for example, 38° C.), the operation control unit 306 controls the heater 8 according to the predicted value described later. The energization level corresponding to the external air temperature is energized. Thereby, it is possible to adjust the temperature of the sheet-like portion 2c to the set temperature at an early stage. In addition, in this embodiment, for example, as shown in FIG. 6 , the energization level is set according to the energization rate of the heater 8 . The energization level is not particularly limited, and may be set according to the performance of the heater 8 and the like, for example. Also, for example, in the present embodiment, when the operation control unit 306 operates the Peltier element 4, the conduction rate is 100%.

The previous operation judging unit 301 judges based on the initial first temperature T1 acquired by the initial first temperature acquiring unit 201 and the initial second temperature T2 acquired by the initial second temperature acquiring unit 202 when the pet temperature regulating device 100 is powered on. The previous operating state in the temperature regulating device 100 for pets. The previous operating state is, for example, a heating mode, a cooling mode, or a non-use state. In addition, the non-use state is, for example, a state in which the temperature of each part of the pet temperature regulating device 100 is averaged according to the outside air temperature, or a state in which the pet temperature regulating device 100 has not been used for a long time.

When |T1-T2|≦X (for example, 3°C), the previous operation determination unit 301 determines that it is in the non-use state. This X is, for example, a value detection error detected by the preset first thermistor 10 and second thermistor 11 , and is a value obtained by, for example, experiments in advance. In other words, the previous operation determination unit 301 determines that each part of the temperature regulating device for pets 100 has adapted to the outside air temperature and is at about the same temperature as the outside air temperature when the temperature of the part separated from the sheet portion 2c and the radiator 5 is approximately the same. state (do not use state).

Moreover, when T2>T1+X, the previous operation determination part 301 determines that it operated in air-conditioning mode last time. This is because, in the case of running in air-conditioning mode, T2 becomes higher than the outside air temperature due to the operation of the Peltier element 4 and the heat sink 5 becomes high temperature, and the sheet-like portion 2c is cooled so that T1 becomes lower than the outside air temperature. As a result, Only T2 becomes high temperature.

Moreover, when T1>T2+X, the previous operation determination part 301 determines that it operated in the heating mode last time. This is because, in the case of running in the heating mode, since the heater 8 has been activated As a result, T1 becomes high, and since the Peltier element 4 does not operate, T2 hardly changes from the outside air temperature, and as a result, T1 becomes high temperature.

The outside air temperature prediction unit 302 predicts the predicted outside air temperature of the pet temperature regulating device 100 based on the determination of the previous operation determination unit 301 . The outside air temperature prediction unit 302 predicts the predicted outside air temperature as T1 when the previous operation determination unit 301 determines that the vehicle is not in use. As described above, this is because, in the non-use state, T1 and T2 have substantially the same value as the outside air temperature. Therefore, although the predicted outside temperature is T1 above, this predicted outside temperature may be predicted as T2 or may be predicted as (T1+T2)/2 in consideration of errors and the like.

Moreover, the outside air temperature prediction unit 302 predicts the predicted outside air temperature as T1+Y when the previous operation determination unit 301 judged that the operation was performed in the air-conditioning mode last time. This Y (for example, 5° C.) is a limit value of the cooling capability of the Peltier element 4 that can be lowered from the actual outside air temperature, and is a value obtained by experiments or the like, for example. In the air-cooling mode, the Peltier element 4 usually cools the sheet-like portion 2c at the maximum output, so it can be judged that the outside air temperature is higher than T1 by the degree Y. In addition, although the above-mentioned outside air temperature prediction unit 302 predicts the predicted outside air temperature based on the temperatures detected by the first thermistor 10 and the second thermistor 11, it is not limited thereto. special limited.

In addition, the outside air temperature prediction unit 302 predicts the predicted outside air temperature as T2 when the previous operation determination unit 301 judged that the operation was in the heating mode the previous time. As described above, this is because T2 hardly changes from the outside air temperature since the Peltier element 4 does not operate in the heating mode operation.

In this manner, the outside air temperature can be predicted from the first thermistor 10 that detects the temperature of the sheet portion 2 c and the second thermistor 11 that protects the Peltier element 4 . Also, even if not much time has elapsed since the previous operation in cooling mode or heating mode, the first thermistor 10 or the second thermistor When the temperature of the sensitive resistor 11 is different from that of the outside air temperature, the outside air temperature can be estimated from the temperature difference between the first thermistor 10 and the second thermistor 11 .

Therefore, without separately providing a thermistor for detecting the outside air temperature, it is possible to energize the heater 8 at an energization level corresponding to the predicted outside air temperature. The energization rate control based on the predicted outside air temperature will be described below.

The initial energization level information acquiring unit 303 acquires initial energization level information indicating the energization rate to the heater 8 based on the predicted outside air temperature predicted by the outside air temperature predicting unit 302 . Specifically, the initial energization level information acquisition unit 303 acquires the initial energization level information associated with the predicted outside air temperature and the energization level, for example, as shown in FIG. 7 . Furthermore, the initial energization level information acquisition unit 303 acquires initial energization level information based on the predicted outside air temperature. This initial energization level is grasped and set by preliminary experiments and the like. In addition, the above-mentioned initial energization level information corresponds to control information in the scope of the patent application.

The operation control unit 306 starts to energize the heater 8 based on the above-mentioned initial energization level information. More specifically, the initial energization level information acquiring unit 303, for example, when the outside air temperature predicting unit 302 predicts the predicted outside air temperature as 22°C, based on FIG. 30°C associated initial energization level information: 4. Then, the operation control unit 306 energizes the heater 8 at level 4 based on the initial energization level information: 4 .

The temperature acquisition unit 304 for adjusting the set temperature acquires the temperature T3 for adjusting the set temperature from the first thermistor 10 . The temperature acquisition unit 304 for setting temperature adjustment, for example, starts to energize the heater 8 by the operation control unit 306 based on the initial energization level information or the energization level information for setting temperature adjustment described later, and passes through the timer unit 103 every time. For a predetermined period of time (for example, 10 minutes) of measurement, the temperature T3 for setting temperature adjustment is acquired.

The energization level information acquisition unit 305 for setting temperature adjustment acquires energization level information for setting temperature adjustment based on the temperature T3 for setting temperature adjustment. Specifically, the set temperature adjustment is energized with For example, as shown in FIG. 8 , the level information acquisition unit 305 acquires the temperature T3 for temperature adjustment and the energization level related information for temperature adjustment associated with the energization level change information. Then, from the acquired energization level change information and the current energization level to which heater 8 is energized, energization level information for setting temperature adjustment is acquired. This energization level change information is grasped and set through preliminary experiments and the like. Then, the operation control unit 306 energizes the heater 8 based on the set temperature adjustment energization level information. More specifically, for example, when 35° C. is acquired as the set temperature adjustment temperature T3, the set temperature adjustment energization level information acquisition unit 305 acquires the set temperature adjustment use temperature T3: less than 36° C. Information: +1. And, when the heater 8 is energized at level 4 as in the above example, the energization level information for setting temperature adjustment: 5 is obtained from the obtained energization level change information: +1 and 4 of level 4. Then, the operation control unit 306 energizes the heater 8 at level 5 based on the set temperature adjustment energization level information: 5 . Thereby, the sheet-shaped part 2c can be adjusted to a preset temperature substantially. In addition, the above-mentioned energization level information for setting temperature adjustment is equivalent to control information in the scope of the patent application.

As described above, after the operation control unit 306 energizes the heater 8 based on the energization level information for setting temperature adjustment, it also obtains the energization level information for setting temperature adjustment based on the temperature T3 for setting temperature adjustment. energization level information, energization to the heater 8. Thereby, the temperature of the sheet-shaped part 2c can be adjusted substantially to a preset temperature. In addition, the configuration of the sheet-shaped portion 2c such as the temperature-adjusting temperature obtaining unit 304, the energization level information obtaining portion 305 for setting the temperature adjustment, and the temperature-adjusting portion 203 is taken as an example. If the temperature of the sheet-shaped portion 2c is approximately The configuration for maintaining at the set temperature is not limited to the configuration described above.

FIG. 9 is a diagram showing an example of the flow of the operation control unit 306 of the pet temperature regulating device 100 according to the present embodiment. As shown in FIG. 9 , when the power is turned on, the initial first temperature acquisition unit 201 acquires the initial first temperature T1 from the first thermistor 10 ( S101 ). The initial second temperature acquisition unit 202 acquires the initial second temperature T2 from the second thermistor 11 (S102). The previous operation determination unit 301 is based on The initial first temperature T1 and the initial second temperature T2 are used to determine the previous operation before power-on of the pet thermostat 100 (S103). This previous operation determination unit 301 determines that the previous operation is within |T1-T2|≦X (X is a predetermined error value in the first thermistor 10 and the second thermistor 11) as the non-use state , in the case of T2>T1+X, it is determined to be the air-conditioning mode, and in the case of T1>T2+X, it is determined to be the heating mode. Based on the determination result of the previous operation determination unit 301, the outside air temperature prediction unit 302 predicts the predicted outside air temperature as T1 when the previous operation was in the non-use state, and predicts T1+Y when the previous operation was in the air-conditioning mode. (Y is the limit value of the cooling capability of the Peltier element 4 that can be lowered from the outside air temperature), and it is predicted to be T2 when the previous operation was in the heating mode (S104). The initial energization level information acquisition unit 303 acquires initial energization level information based on the predicted outside air temperature ( S105 ). The operation control unit 306 starts energization to the heater 8 at the acquired energization level based on the initial energization level information (S106). The temperature acquisition part 304 for set temperature adjustment acquires the temperature T3 for set temperature adjustments from the 1st thermistor 10 (S107). The energization level information acquisition unit 305 for setting temperature adjustment acquires the energization level information for setting temperature adjustment based on the temperature T3 for setting temperature adjustment (S108). Then, the operation control unit 306 energizes the heater 8 at the set temperature saving energization level acquired based on the set temperature adjustment energization level information (S109). After S109, return to S107, and by repeating S107 to S109, the temperature of the sheet portion 2c is substantially fixedly adjusted to the set temperature. In addition, when the power supply of the temperature adjustment device 100 for pets is turned off, the above-mentioned flow is also terminated. In addition, this embodiment is not limited to the above-mentioned flow, Various deformation|transformation is possible. For example, the order of S101 and S102 may be reversed or simultaneous.

According to this embodiment, based on the first temperature obtained from the first thermistor 10 and the second temperature obtained from the second thermistor 11, the Peltier element 4 or the heater 8 can be controlled to provide a A thermoregulator for pets that regulates the temperature of the sheet portion 2c. Thereby, the temperature of the sheet-like portion 2c of the heat conductor can be adjusted to a temperature comfortable for the pet. In addition, since it is possible to predict the external air temperature from the above-mentioned first temperature and second temperature by using the temperature adjustment device for pets, The outside air temperature prediction unit predicts the outside air temperature, and can adjust the temperature of the sheet-like portion 2c of the heat conductor without installing a sensor for detecting the outside air temperature separately from the first thermistor and the second thermistor 11 .

Also, according to the present embodiment, the initial energization rate of the heater 8 is controlled based on the outside air temperature predicted by the outside air temperature prediction unit, and when the first thermistor 10 is close to the set temperature, the energization rate is adjusted based on the set temperature. Level information changes the energization rate of the heater 8 . Thereby, even when the outside air temperature is predicted to be low, the temperature of the sheet portion 2c can be brought to the set temperature early. On the other hand, when the outside air temperature is predicted to be high, it is possible to prevent the The temperature is set to be high temperature, and the pet feels uncomfortable.

The present invention is not limited to the above-mentioned embodiments, and may be replaced with substantially the same configuration, a configuration having the same operation and effect, or a configuration capable of achieving the same purpose as the configuration shown in the above-mentioned embodiment.

For example, the operation control unit 306 may energize the heater 8 at level 10 with a maximum energization rate of 100% for a predetermined period after the power is turned on or until the first thermistor 10 reaches a predetermined temperature. The user puts in the power supply of the temperature regulating device for pets because he wants to change the temperature of the sheet part 2c rapidly through the heating mode and the cooling mode. Therefore, the heater 8 is first energized at a level of 100% of the maximum energization rate. Alleviate user dissatisfaction. Also in this case, it is preferable to change the predetermined period and the predetermined temperature during which electricity is supplied at the maximum energization rate according to the predicted outside air temperature.

Also, for example, in addition to the above-mentioned configuration, a protection control information acquisition unit for preventing an excessive rise in temperature of the sheet portion 2c may be included. The protection control information acquisition unit acquires protection control information for stopping energization to the heater 8 when the temperature detected by the first thermistor 10 exceeds a predetermined temperature (for example, 50° C.), for example. The temperature adjustment unit 203 stops energization to the heater 8 based on this protection control information. Thereby, for example, pets can be prevented from being scalded, and safety can be ensured. In addition, after the energization is stopped, for example, at the temperature detected by the first thermistor 10 When the temperature is lower than a predetermined temperature (for example, 30° C.), the heater 8 may be re-energized based on the predicted temperature predicted by the outside air temperature prediction unit 302 .

In addition, in this embodiment, when the power supply of the temperature regulating device 100 for pets is turned on, although the user designates the heating mode, for example, the sheet-shaped part 2c will be adjusted by the Peltier element 4 according to the external air temperature. A mode switching unit for switching between an air-conditioning mode for cooling or a heating mode for heating the sheet-like portion 2c by the heater 8 . For example, the mode switching unit operates in the air-conditioning mode when the predicted outside air temperature predicted by the above-mentioned outside air temperature predicting unit 302 is above a predetermined temperature (for example, 25° C.) It is configured to operate in heating mode. Thereby, the user does not need to designate the operation mode, and the convenience of the user can be improved.

(Second Embodiment)

Next, a second embodiment of the present invention will be described. In addition, description of the same points as those of the first embodiment will be omitted below.

Fig. 10 is a diagram for explaining an example of the functional configuration of the control unit of the temperature regulating device for pets in the present embodiment. As shown in FIG. 10 , the control unit 101 of the pet temperature regulating device 100 in this embodiment functionally includes, for example, a pet determination first temperature acquisition unit 401, a pet determination second temperature acquisition unit 402, a pet presence determination unit 403 . The temperature adjustment unit 203 . Although the initial state of the temperature regulating device 100 for pets in this embodiment is, for example, a state in which the power supply to heating and cooling elements such as the Peltier element 4 and the heater 8 is cut off by a timer, at least it is set as a controlled state. The power supply of the unit 101 is in a state of being inserted.

The pet determination first temperature acquisition unit 401 acquires the sheet-like temperature detected by the first thermistor 10 at a time t of a predetermined elapsed time (for example, 2 minutes) measured by the timer unit 103 after the power supply to the heating and cooling element is cut off each time. The temperature of the portion 2c is the first pet determination temperature T4.

The pet determination second temperature acquisition unit 402, for example, acquires the temperature detected by the second thermistor 11 at time t of a predetermined elapsed time (for example, 2 minutes) measured by the timer unit 103 after each cut off of the power supply to the heating and cooling element. The temperature of the radiator 5 is the pet determination second temperature T5.

The pet presence determination unit 403 determines whether or not a pet is sitting on the sheet portion 2 c based on the first pet determination temperature T4 and the second pet determination temperature T2 . When it is determined that the pet is sitting on the sheet portion 2c, for example, the temperature regulator 203 re-energizes heating and cooling elements such as the Peltier element 4 and the heater 8 to adjust the temperature of the sheet portion 2c. For example, in this embodiment, the operation mode (cooling mode or heating mode) at the time of cutting off the power supply to the heating and cooling elements is memorized, and the temperature control of the sheet portion 2c is restarted based on the determination of the pet presence determination unit 403. At this time, the temperature of the sheet portion 2c is adjusted to a predetermined set temperature by operating in the previous operation mode that has been memorized.

More specifically, the pet presence determination unit 403 determines that the pet is on board, for example, when T4 and T5 acquired at time t are T4-T5>X. In addition, X is, like the first embodiment, a detection error of values detected by, for example, preset first thermistor 10 and second thermistor 11 , and is a value obtained by experiments in advance, for example.

In addition, in the heating mode, the pet presence determination unit 403 determines whether or not the pet is riding, for example, based on the slope in the relationship between time t and T4, except for the above-mentioned case of T4-T5>X. More specifically, for example, the pet presence determination unit 403 bases the time t(x+1 ) calculated slope of T4(x+1): {T4(x+1)-T4(x)}/{t(x+1)-t(x)}, for example, where the slope is greater than the threshold (for example -1) In the case of large, and in the case of T4-T5>X, it is determined whether or not the pet is sitting on the sheet portion 2c. In addition, the above-mentioned threshold is set in advance by experiments or the like.

The determination in the pet presence determination unit 403 will be described more specifically with reference to the temperature change in the pet temperature adjustment device in FIGS. 11 to 22 .

Hereinafter, (A), (1)-(3) in summer, and (B), (4)-(6) in winter will be divided into patterns, and it will demonstrate based on FIGS. 11-18. 11 to 18 show the relationship between the elapsed time after the power supply to the heating and cooling element is cut off, and the pet determination first temperature T4 and the pet determination second temperature T5. The portion surrounded by a dotted line in the figure indicates the time when the pet is riding on the sheet portion 2c, and the portion surrounded by a chain line represents the time when the pet presence determination unit 403 judges that the pet is riding on the sheet portion 2c. In addition, in FIGS. 11 to 18 , in order to clarify the temperature change due to the pet sitting, the temperature change due to the energization of the heating and cooling elements is excluded.

The types of (A), (1)~(3), and (B), (4)~(6) are as follows.

(A) In summer (for example, the outside air temperature is 30° C.), the pet does not sit on the sheet part 2c after the power is cut off during the operation in the air-conditioning mode. (1) In summer, the power is cut off during the operation in the air-conditioning mode. Afterwards, when the temperature adjustment device 100 for pets adapts to the outside air temperature and becomes the same temperature as the outside air temperature, when the pet rides, (2) in summer, after the power is cut off during the operation in the air-conditioning mode, the temperature adjustment device for pets Before the device 100 adapts to the outside air temperature, when the pet rides, (3) In summer, the pet rides in the air-conditioning mode, and when the power is cut off, the pet stays on the ride, (B) In winter (for example, the outside air temperature is 20°C) , after the power supply is cut off during the operation of the heating mode, the pet does not sit on the sheet portion 2c, (4) in winter, after the power supply is cut off during the operation of the heating mode, the temperature adjustment device 100 for pets adapts to the outside air temperature , in the state where the temperature is the same as the outside air temperature, when the pet rides, (5) in winter, after the power supply is cut off during the heating mode operation, before the pet temperature adjustment device 100 adjusts to the outside air temperature, the pet rides, (6) In winter, the pet rides while the heating mode is operating, and the pet stays on the ride when the power is cut off.

In the case of the type (A), for example, as shown in FIG. 11 , at the time (0 minute) when the energization is cut off, since the Peltier element 4 is operating originally, T5 becomes high temperature, and the sheet portion 2c is Cooling T4 is lower than the outside air temperature (30°C). In addition, T5 decreases with the lapse of time and becomes substantially the same as the outside air temperature 10 minutes later. On the other hand, T4 rises with the lapse of time and becomes substantially the same as the outside air temperature after 10 minutes. In this way, the temperature adjustment device 100 for pets becomes T4≒T5 by adapting to the external air temperature, and then T4 and T5 do not change substantially because the pet does not ride.

In the case of the pattern (1), for example, as shown in FIG. 12 , T4 and T5 have substantially the same temperature from the acquisition start to 28 minutes, and it can be judged that they are adapted to the outside air temperature. And, the pet rides on the sheet part 2c after 28 minutes, and T4 rises after 30 minutes. The temperature rise in T4 30 minutes later can be judged to be due to the rise in body temperature of the pet sitting on the sheet portion 2c in view of adapting to the outside air temperature. On the other hand, T5 was not affected by pets and hardly changed from the outside air temperature (30°C). Thereby, in the pet presence determination unit 403, when T4-T5>X (in this embodiment, X is, for example, 3° C.), it can be determined that there is a temperature change due to the body temperature of the pet, and it can be determined that the pet is Ride on the sheet part 2c.

In the case of the pattern (2), for example, as shown in FIG. 13 , since T5 is not affected by pets, it shows the behavior to the temperature drop adapted to the outside air temperature as in the case of (A). On the other hand, T4 is the same as the case of (A) at the initial stage after the power is cut off, and it rises as time passes so that it approaches the outside air temperature. After 4 minutes, the pet rides, and after that, even if it exceeds the outside air temperature (30 °C) also rises further, exceeding T5 after 10 minutes. The rise of T4 over T5 can be judged as a temperature change caused by the pet’s body temperature since T5 will only drop to the outside air temperature. change. Thereby, the pet presence determination unit 403 can determine that there is a temperature change in body temperature due to the pet when T4-T5>X, and determine that the pet is sitting on the sheet portion 2c.

In the case of the pattern (3), for example, as shown in FIG. 14 , since T5 is not affected by pets, it shows the behavior to the temperature drop adapted to the outside air temperature as in the case of (A). On the other hand, since T4 was previously cooled in the air-conditioning mode, it rises after the power is turned off, and in a region higher than the outside air temperature (30°C), it rises to approach the pet's body temperature over time. And, after 8 minutes, T4 exceeds T5. The rise of T4 over T5 can be judged as the effect of maintaining the body temperature of the pet sitting on the sheet portion 2c, since T5 is only lowered to the outside air temperature. Thereby, in the pet presence determination unit 403, when T4-T5>X, it can be determined that there is a temperature change due to the body temperature of the pet, and it can be determined that the pet is sitting on the sheet portion 2c. In this way, even if the pet stays seated when the power supply is cut off by a timer or the like, the temperature regulating device 100 for pets does not immediately re-energize, and does not re-energize until T4 does not exceed T5. Therefore, since the continuous energization state of the Peltier element 4 is avoided, the energization is stopped until the heat sink 5 is cooled, and damage to the Peltier element 4 can be prevented.

In the case of type (B), for example, as shown in FIG. 15 , at the power-off time (0 minute), since the Peltier element 4 does not operate at first, T5 is approximately the same as the outside air temperature (20°C). T4 is originally heated by the heater 8 and becomes higher than the outside air temperature. And, as time passes, T5 continues to be at the same temperature as the outside air temperature without change. On the other hand, T4 becomes substantially the same as the outside air temperature 10 minutes after the decrease. In this way, the temperature adjustment device 100 for pets becomes T4≒T5 by adapting to the external air temperature, and then T4 and T5 do not change substantially because the pet does not ride.

In the case of the pattern (4), for example, as shown in FIG. 16 , T4 and T5 become substantially the same temperature from the acquisition start to 28 minutes, and it can be judged that the pet temperature regulating device 100 has adapted to the outside air temperature. Also, since T5 is not affected by pets, the Peltier element 4 does not operate in the heating mode, and there is almost no change from the outside air temperature (20° C.) as in the case of (B). And, the pet rides on the sheet part 2c after 28 minutes, and only T4 rises after 30 minutes. 30 minutes here The temperature rise of T4 after the clock is adjusted to the outside air temperature, and it can be judged that the rise is due to the body temperature of the pet sitting on the sheet portion 2c. Thereby, in the pet presence determination unit 403, when T4-T5>X, it can be determined that there is a temperature change due to the body temperature of the pet, and it can be determined that the pet is sitting on the sheet portion 2c.

In the case of the type (5), for example, as shown in FIG. 17, at the power-off time (0 minute), as in (B), since the Peltier element 4 was not in motion, T5 and the outside air temperature (20°C ) is roughly the same, because T4 is heated by the heater 8 originally, and becomes higher than the external air temperature. Also, since T5 is not affected by pets, the Peltier element 4 does not operate in the heating mode, and there is almost no change from the outside air temperature (20° C.) as in the case of (B). On the other hand, T4 falls close to the outside air temperature as in (B), but after 4 minutes the pet sits on the sheet portion 2c, so the body temperature of the pet starts to rise. In this type (5), as shown in Figure 17, since T4-T5>X has already become at the time of power-off (0 minutes), as shown in the above (A), (1)~(3) In the air-conditioning mode, it cannot be determined that the pet is riding on the sheet portion 2c at the time when T4-T5>X. Therefore, the pet presence determination section 403 determines the presence of the pet from the above-mentioned slope calculated from the time t and T4. The slope of this calculation is shown in Figure 19. As shown in FIG. 19 , the slope after the above-mentioned pet rides for 4 minutes is as small as -2, and then 6 minutes later, the slope becomes 0 greater than -1 (threshold value in this embodiment) due to the increase in the pet's body temperature T4. In other words, as described above, the pet presence determination unit 403 satisfies T4-T5=12°C>X (3°C in this embodiment) at the time obtained by T4 after 6 minutes, and the slope>-1 (in this embodiment Threshold), it is determined that the pet is riding.

In the case of the type (6), for example, as shown in FIG. 18, at the power-off time (0 minute), as in (B), since the Peltier element 4 does not operate originally, T5 and the external air temperature (20°C ) is roughly the same, because T4 is heated by the heater 8 originally, and becomes higher than the external air temperature. Also, since T5 is not affected by pets, the Peltier element 4 does not operate in the heating mode, and there is almost no change from the outside air temperature (20° C.) as in the case of (B). On the other hand, T4 Because the pet keeps sitting on the sheet portion 2c, the temperature change after 2 minutes compared with the type (5) is moderated by the body temperature of the pet. Here, in the pattern (6), as shown in FIG. 18 , since T4-T5>X is the same as in the pattern (5), the pet presence determination unit 403 judges from the above-mentioned slope calculated from the time t and T4. the presence of pets. The slope of this calculation is shown in Figure 20. As shown in FIG. 20, since the slope after 2 minutes, as mentioned above, the influence of the body temperature of the pet is milder than the temperature decrease in the pattern (5), it becomes greater than -1 (threshold value of this embodiment) -0.5. In other words, as described above, the pet presence determination unit 403 determines that the pet is on board when T4-T5=18°C>X and the slope>-1 (threshold value in this embodiment) at the time after 2 minutes.

In addition, as long as it can be determined that the pet is sitting on the sheet part 2c, the determination of the pet sitting on the sheet part 2c in the pet presence determination part 403 is not limited to the above-mentioned configuration. In addition, in this embodiment, the detection error in the first thermistor 10 and the second thermistor 11 is taken into consideration, but it may be judged without taking the detection error into consideration. In addition, when the above-mentioned patterns (1) to (6) are not met, for example, in the case of patterns (A) and (B), it can be determined that the pet is not riding.

In addition, whether or not the pet is riding may be determined based on the slope of the relationship between time t and (T4-T5) instead of the slope of the relationship between time t and T4. By judging with the value of T4-T5, it is possible to prevent malfunction when the outside air temperature changes rapidly.

FIG. 21 is a diagram showing an example of the flow of the pet temperature regulating device 100 in this embodiment. As shown in FIG. 21 , the pet determination first temperature acquisition unit 401 acquires the pet determination first temperature T4 at time t every predetermined elapsed time ( S201 ). The pet determination second temperature acquisition unit 402 acquires the pet determination second temperature T5 at time t every predetermined elapsed time (S202). The pet presence determination unit 403 determines whether or not the pet is sitting on the sheet portion 2c based on T4 and T5 (whether the pet exists on the sheet portion 2c) (S203). More specifically, for example, in the air-conditioning mode, the pet presence determination unit 403 determines that the pet is on board when T4-T5>X. Also, in the heating mode, when the above T4-T5>X is met, and, for T4, the slope ratio threshold calculated from the relationship between time t and T4 (For example -1) is large, it is determined that the pet is riding. When it is determined that the pet is sitting on the sheet portion 2c, the temperature control unit 203 turns on the power supply to the heating and cooling elements of the pet temperature control device 100 to adjust the temperature of the sheet portion 2c (S204). In addition, this embodiment is not limited to the above-mentioned flow, Various deformation|transformation is possible. For example, the order of S101 and S102 may be reversed or simultaneous.

According to the present embodiment, based on the temperature obtained from the first thermistor 10 and the second thermistor 11, by using the pet presence determination unit 403 to determine the presence of a pet on the sheet portion 2c, it is possible to eliminate the need for additional weight sensors. Other parts such as, in the case that the pet exists in the sheet portion 2c, adjust the temperature of the sheet portion 2c. Thus, for example, in the state where the power supply to the heating and cooling elements is cut off by a timer, etc., when the pet sits on the sheet portion 2c, the temperature adjustment of the sheet portion 2c can be automatically restarted, so that the comfort of the pet can be improved. promote.
