Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and drawings, the same or equivalent elements are denoted by the same reference numerals to omit overlapping description, and elements not directly related to the present invention may be omitted. The embodiments of the constituent elements shown in the embodiments are merely examples, and are not limited to these embodiments.
Hereinafter, a temperature control device 100 for pets according to embodiment 1 of the present invention will be described. Fig. 1 is a perspective view of a temperature control device 100 for pets according to embodiment 1. Fig. 2 is a side view of the thermostat 100 for pets of fig. 1. Fig. 3 is a sectional view of the temperature control device 100 for pet of fig. 1 as viewed along the line III-III. Fig. 4 is a sectional view of the pet thermostat 100 of fig. 2 viewed in the direction of line IV-IV.
The pet thermostat 100 includes a base 101, a heat conductor 102, and a case 103.
The foundation 101 is disposed on the ground or the like, and supports the heat conductor 102 and the case 103.
The heat conductor 102 is a substantially L-shaped plate-like member formed by bending one plate at a middle portion thereof. The heat conductor 102 includes a sheet-like thin portion 102a that is arranged parallel to the ground and on which an object such as a cat or a dog (hereinafter, also referred to as a pet) is placed to sleep or rest, and an upright portion 102b that is formed to be upright substantially perpendicularly from one end of the thin portion 102a. Sheet portion 102a is provided so as to protrude laterally from case 103, and is exposed from case 103. One end side of the thin section 102a and the rising section 102b are housed in the case 103. In the heat conductor 102, the surface on which the pet sleeps or rests is referred to as a front surface, and the surface opposite thereto is referred to as a back surface.
The case 103 is a substantially rectangular parallelepiped shape with a round shape, and is provided so as to partially cover the foundation 101 and the heat conductor 102. One side surface (the surface on the side from which sheet portion 102a projects) of case 103 is formed as wall portion 103a. The wall portion 103a is formed of a smooth curved surface and is formed to rise upward from one end side of the thin portion 102a. The wall portion 103a also functions as a backrest on which a pet rests. The case 103 is provided to cover a cooling mechanism described later.
The temperature control device for pet 100 includes at least one of a cooling mechanism and a heating mechanism as a temperature control unit. In the present embodiment, the cooling mechanism and the heating mechanism are separately provided. The thermal conductor 102 is cooled or heated by applying current to the temperature adjustment unit (cooling means or heating means). The heat conductor 102 is preferably formed of a plate-like member made of a heat conductive material such as aluminum, copper, steel, or stainless steel, for example, in order to conduct heat from the temperature adjustment portion. The heat conductor 102 is preferably formed of an aluminum plate in consideration of heat conductivity, workability, cost, and the like.
The pet thermostat 100 includes a Peltier Element (Peltier Element) 111 as a cooling mechanism, a heat sink 112 provided as a heat radiation mechanism, and a fan 113. The cooling mechanism is provided on the back side of the rising portion 102b and is housed in the case 103.
The peltier element 111 is a thermoelectric conversion element for cooling at least the heat conductor 102, and is mounted so as to be in contact with the back surface side of the rising portion 102b. The peltier element 111 cools the thermal conductor 102 by applying a temperature difference between the thermal conductor 102 and the heat sink 112, for example, by applying current. Thereby, a temperature gradient is formed such that the temperature increases from one end side (rising portion 102b side) of the thin portion 102a toward the other end side (opposite to the rising portion 102 b).
The cooling mechanism (peltier element 111) is provided on one end side of the sheet portion 102a, but is not limited thereto. A temperature gradient may be formed in sheet portion 102a, and may be provided at the other end of sheet portion 102a, for example.
The heat sink 112 is a heat sink for dissipating heat generated in the peltier element 111, and is provided so as to be in contact with the peltier element 111. The heat sink 112 includes a rectangular plate-like portion 112a and a plurality of fins 112b extending perpendicularly from the plate-like portion 112a and arranged substantially parallel to the long side of the plate-like portion 112 a. The fan 113 is provided so as to face the heat radiation fins 112b of the radiator 112, and blows air to the radiator 112 to cool it. In the present embodiment, the heat radiating fins 112b are arranged substantially parallel to the long sides of the plate-shaped portion 112a, but the present invention is not limited to this. For example, the fins 112b may be arranged substantially parallel to the short sides of the plate-shaped portion 112 a.
The shape of the rising portion 102b of the thermal conductor 102 is preferably matched to the size of the peltier element 111, the heat sink 112, and the like, for example. In the present embodiment, the peltier element 111 is used as a cooling mechanism for the heat conductor 102, but is not limited thereto. For example, the direction and intensity of the current may be changed to be used as a heating mechanism for heating the heat conductor 102.
The heating mechanism is constituted by a heater 120. The heater 120 is, for example, a sheet-like aluminum heater, and is provided on the rear surface of the sheet portion 102a. Heater 120 is provided on one end side (rising portion 102b side) of sheet portion 102a, and heats heat conductor 102 by energization. Thereby, a temperature gradient is formed such that the temperature decreases from one end side (rising portion 102b side) of the thin portion 102a toward the other end side (opposite to the rising portion 102 b).
The heater 120 is provided on one end side of the sheet portion 102a, but is not limited thereto. Heater 120 may be energized to form a temperature gradient in sheet portion 102a, or heater 120 may be provided on the other end side of sheet portion 102a. Further, the heater 120 may be disposed across the entire sheet portion 102a, and the density of the electric heating wires constituting the heater 120 may be changed to form a temperature gradient in the sheet portion 102a. Further, heater 120 may be disposed across the entire sheet portion 102a, and peltier element 111 may be used as a heating mechanism for heat conductor 102, thereby forming a temperature gradient in sheet portion 102a.
Between the sheet portion 102a and the foundation 101, a heat insulating member 121, a heater 120, and an insulating sheet 122 are stacked in this order from the foundation 101 side, and supported by the foundation 101. The heat insulating member 121 suppresses radiation (radiation) of heat from the sheet portion 102a to the ground, and is formed of, for example, styrofoam or the like. Insulating sheet 122 is formed of an insulating resin or the like to insulate sheet portion 102a and heater 120. This enables the sheet portion 102a to be heated.
The sheet portion 102a is provided with sensor portions for detecting the presence or absence of an object (pet) in each of the plurality of regions. In the sheet portion 102, a temperature gradient is formed by applying current to the temperature adjustment portion. The plurality of regions are distinguished based on the magnitude of the temperature change in the sheet portion 102a due to the energization of the temperature adjustment portion. The plurality of regions are configured to include at least one region in which a temperature change due to the energization of the temperature adjustment portion is large and another region in which a temperature change due to the energization of the temperature adjustment portion is small. In other words, the plurality of regions are configured to include two different points of temperature change due to energization of the thermoregulator in the sheet portion 102a. In the present embodiment, the plurality of regions are constituted by a region on one end side of the sheet portion 102a (region near the temperature adjusting portion) and a region on the other end side of the sheet portion 102a (region apart from the temperature adjusting portion).
The sensor unit is configured by, for example, a plurality of temperature sensors (in the present embodiment, the temperature sensor 114 and the temperature sensor 115) that detect the temperature of each region. In the pet thermostat 100, the presence or absence of an object is detected for each zone based on the temperature difference between the detected temperature of a temperature sensor (sheet temperature described later) and the predicted temperature at the position where the temperature sensor is disposed in a state where the object (pet) is not present.
Specifically, the temperature sensor 114 detects the temperature (sheet temperature Th 1) at a specific position in the region on one end side of the sheet portion 102a. The sheet temperature Th1 is hereinafter also referred to as a detected temperature Th1. In the pet thermostat 100, the presence or absence of an object is detected based on a temperature difference between the detected temperature Th1 of the temperature sensor 114 and the predicted temperature Th1' of the position (specific position in the region on the one end side) where the temperature sensor 114 is disposed.
Similarly, the temperature sensor 115 detects the temperature (sheet temperature Th 2) of a specific position in the region on the other end side of the sheet portion 102a. The sheet temperature Th2 is hereinafter also referred to as a detection temperature Th2. In the pet thermostat 100, the presence or absence of an object is detected based on the temperature difference between the detected temperature Th2 of the temperature sensor 115 and the predicted temperature Th2' of the position (specific position in the region on the other end side) where the temperature sensor 115 is disposed.
As shown in fig. 4, two duct forming members 201 are disposed in an internal space formed from the other side surface (a surface facing the air intake side of the fan 113) of the case 103 to the heat sink 112, thereby forming an air intake path 202 and an air exhaust path 203. The other side surface of the case 103 is formed with an opening for allowing air to flow between the outside. Of the openings, a portion (central portion) corresponding to the air intake passage 202 functions as an air intake port 202 a. In the opening, the portion (both end portions) corresponding to the exhaust path 203 functions as an exhaust port 203 a. In the above configuration, the pet thermostat 100 sucks air from the air inlet 202a through the air suction path 202 and discharges air from the air outlet 203a through the air discharge path 203.
A temperature sensor 204 is provided in the vicinity of the inlet port 202 a. The temperature sensor 204 is provided in the vicinity of the air inlet 202a, and thereby functions as an outside air temperature sensor that detects the outside air temperature Th3. The temperature sensor 204 is provided near the air inlet 202a, but is not limited to this, as long as it can detect the outside air temperature Th3.
An electronic control box 205 is provided in the internal space of the housing 103. The electronic control box 205 houses an electronic control device for controlling the operation of the pet thermostat 100 such as a power board and a control board. The electronic control box 205 is provided in a space inside the case 103 isolated from the intake path 202 and the exhaust path 203. Thus, the electronic control box 205 is not exposed to the heat radiated from the radiator 112, and damage to the electronic control apparatus can be prevented.
In the pet thermostat 100, when a user operates an operation tool (not shown), a cold air mode (cooling operation) in which the peltier element 111 is energized to cool the sheet portion 102a and a warm air mode (warming operation) in which the heater 120 is energized to heat the sheet portion 102a can be switched.
The automatic temperature control of the pet thermostat 100 will be described with reference to fig. 5 to 9. Fig. 5 is a block diagram showing a hardware configuration of the pet thermostat 100. As shown in fig. 5, the pet thermostat 100 includes a control unit 300, a timer unit 301, a storage unit 302, a peltier element 111, a heater 120, a temperature sensor 114, a temperature sensor 115, and a temperature sensor 204.
The control Unit 300 is configured with a Memory such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU reads the program stored in the ROM into the RAM and executes the program, thereby controlling the operation of each part of the pet thermostat 100. The timer 301 measures time. The storage unit 302 stores programs executed by the control unit 300 and various parameters, graphs, and the like used in the control unit 300. The control unit 300 is a control board provided in the electronic control box 205 together with the timer unit 301 and the storage unit 302, and is connected to each of the peltier element 111, the heater 120, the temperature sensor 114, the temperature sensor 115, the temperature sensor 204, and the like, and controls each unit, whereby the sheet unit 102a can be adjusted to a temperature zone comfortable for a pet (hereinafter, also referred to as a comfortable temperature zone).
Fig. 6 is a block diagram conceptually showing each function of the control unit 300 for realizing the automatic temperature control by the pet thermostat 100. As shown in fig. 6, the control unit 300 includes a current carrying rate acquisition unit 310, an outside air temperature detection unit 320, a sheet temperature prediction unit 330, a sheet temperature detection unit 340, a calculation unit 350, a determination unit 360, and an operation control unit 370. In the pet thermostat 100, when the cold air mode or the warm air mode is started, the following process is performed after a certain time has elapsed. The specific time is a time until the predicted temperature at the specific energization rate E1 is reached, and is set to 10 minutes, for example.
The current carrying rate acquiring unit 310 acquires the current carrying rate E1 stored in the storage unit 302.
The outside air temperature detecting unit 320 acquires the outside air temperature Th3 detected by the temperature sensor 204.
The sheet temperature predicting unit 330 obtains a predicted temperature Th1 'and a predicted temperature Th2' from the outside air temperature Th3 and the current carrying rate E1, respectively. The predicted temperature Th1' is a temperature reached by applying current at the current application rate E1 to a position where the temperature sensor 114 is disposed. Similarly, the predicted temperature Th2' is a temperature reached by applying current at the current application rate E1 to a position where the temperature sensor 115 is disposed.
The sheet temperature predicting unit 330 compares the energization rate E1 and the outside air temperature Th3 with a reference table shown in fig. 7, and obtains a predicted temperature Th1 'and a predicted temperature Th2', respectively. The reference table shown in fig. 7 is a table showing the correspondence relationship between the sheet temperature Th1 and the predicted temperature Th1 'and the outside air temperature Th3, and the correspondence relationship between the sheet temperature Th2 and the predicted temperature Th2' and the outside air temperature Th3. The reference table shown in fig. 7 is a value set in advance by an experiment or the like, and is stored in the storage unit 302.
The reference table shown in fig. 7 (a) shows the correspondence between the temperatures in the cold air mode, and for example, when the outside air temperature Th3 is 25 ℃ and the current carrying rate E1 is 50%, the predicted temperature Th1 'is 19 ℃ and the predicted temperature Th2' is 21 ℃. The reference table shown in fig. 7 (b) shows the correspondence relationship between the temperatures in the heating mode, and for example, when the outside air temperature Th3 is 10 ℃ and the energization rate E1 is 50%, the predicted temperature Th1 'is 24 ℃ and the predicted temperature Th2' is 20 ℃.
The sheet temperature detecting unit 340 obtains a sheet temperature Th1 (detected temperature Th 1) detected by the temperature sensor 114 and a sheet temperature Th2 (detected temperature Th 2) detected by the temperature sensor 115.
The calculating part 350 calculates a temperature difference between the detected temperature and the predicted temperature. Specifically, the predicted temperature Th1' is subtracted from the detected temperature Th1, thereby calculating the temperature difference Δ Th1. Similarly, the predicted temperature Th2' is subtracted from the detected temperature Th2, thereby calculating the temperature difference DeltaTh 2.
In the determination unit 360, when it is determined that the temperature difference Δ Th1 is larger than the specific threshold value T1, it is assumed that a pet person is present in the region on the one end side of the thin section 102a. In the determination unit 360, when it is determined that the temperature difference Δ Th1 is equal to or less than the specific threshold value T1, it is assumed that no pet person is present in the region on the one end side of the thin section 102a.
Similarly, in the determination unit 360, when it is determined that the temperature difference Δ Th2 is larger than the specific threshold value T1, it is assumed that a pet person is present in the region on the other end side of the thin section 102a. In the determination unit 360, when it is determined that the temperature difference Δ Th2 is equal to or less than the specific threshold value T1, it is assumed that no pet person is present in the region on the other end side of the sheet portion 102a. Thus, the determination unit 360 detects the presence or absence of pets in a plurality of regions of the sheet unit 102a.
Fig. 8 is a graph showing the relationship between the posture of a pet, the temperature sensation of the pet, and the temperature control. As shown in fig. 8 (a), when the temperature of the thin portion 102a has not reached a temperature band comfortable for the pet, the pet receives heat (or cold) from the thin portion 102a by bringing the whole body into close contact with the thin portion 102a as much as possible. Therefore, the pet exists as a whole across the thin section 102a. That is, when the temperature difference Δ Th1 and the temperature difference Δ Th2 are larger than the specific threshold value T1, the thin portion 102a does not reach the comfort temperature zone. The state where the pet does not reach the comfort temperature zone means a state where the pet feels hot in the cold air mode and a state where the pet feels cold in the warm air mode.
When determining unit 360 determines that temperature difference Δ Th1 and temperature difference Δ Th2 are greater than specific threshold value T1, operation control unit 370 increases current carrying rate E1 by the specific current carrying rate. The specific power-on rate is a predetermined value, for example, 10%. Thus, since the temperature of the thin portion 102a can be brought close to the comfortable temperature zone, a more comfortable temperature environment for the pet can be provided.
As shown in fig. 8 (b), when the temperature of the thin portion 102a belongs to the comfort temperature zone, the pet is in a relaxed posture centering on the side where the temperature change by the energization of the thermoregulator is large, and the pet is present centering on the one end side of the thin portion 102a. That is, when only the temperature difference Δ Th1 is larger than the specific threshold T1, it is assumed that the temperature of the thin portion 102a belongs to the comfort temperature zone. The state belonging to the comfortable temperature zone refers to a state in which the pet feels comfortable. Further, by forming the wall portion 103a on the side where the temperature change due to the energization of the temperature adjustment portion is large, when the pet has a habit of having a preferential corner portion (wall portion 103 a), the pet can be induced to approach around the one end side of the thin portion 102a.
In determination unit 360, it is determined that only temperature difference Δ Th1 is greater than specific threshold value T1, and operation control unit 370 maintains current-carrying rate E1. This enables the pet to maintain a comfortable temperature environment. In the present embodiment, operation controller 370 maintains current application rate E1 in the same manner as in the case where determination unit 360 determines that temperature difference Δ Th1 and temperature difference Δ Th2 are equal to or less than specific threshold value T1. The case where the determination unit 360 determines that the temperature difference Δ Th1 and the temperature difference Δ Th2 are equal to or less than the specific threshold value T1 means that the pet is not present in the pet sheet portion 102a.
As shown in fig. 8 (c), when the temperature of the thin portion 102a exceeds the comfort temperature zone, the pet moves away from the side where the temperature change due to the energization of the thermoregulator is large and toward the side where the temperature change due to the energization of the thermoregulator is small, and the pet is present centering on the other end side of the thin portion 102a. That is, when only the temperature difference Δ Th2 is larger than the specific threshold value T1, it is assumed that the temperature of the thin portion 102a exceeds the comfort temperature zone. The state exceeding the comfort temperature zone means a state in which the pet feels a little cold in the case of the cold air mode, and a state in which the pet feels a little hot in the case of the warm air mode.
When determining unit 360 determines that only temperature difference Δ Th2 is greater than specific threshold value T1, operation control unit 370 decreases current carrying rate E1 by the specific current carrying rate. The specific power-on rate is a predetermined value, for example, 10%. Thus, since the temperature of the thin portion 102a can be brought close to the comfortable temperature zone, a more comfortable temperature environment for the pet can be provided.
Fig. 9 is a flowchart showing the automatic temperature control of the temperature control device for pet 100. In the processing of fig. 9, as an example, the user operates the operation tool to start the cooling mode or the heating mode, and the current-carrying rate E1 at the start of the operation is set to an initial current-carrying rate (for example, 50%) set in advance by an experiment or the like. The initial power supply rate is stored in the storage unit 302. After the automatic temperature control and the operation start, a predetermined time elapses, and the process proceeds to step S101. The specific time is a time until the predicted temperature at the time of energization at the energization rate E1 is reached.
The current-carrying rate acquiring unit 310 acquires the current-carrying rate E1 stored in the storage unit 302 during operation (step S101). At the time point when the operation starts, the initial energization rate stored in the storage unit 302 is acquired. The outside air temperature detecting unit 320 receives the detection signal of the temperature sensor 204 and detects the current outside air temperature Th3 (step S102). Next, the sheet temperature predicting unit 330 obtains the predicted temperature Th1 'and the predicted temperature Th2' from the current carrying rate E1 and the outside air temperature Th3, respectively (step S103). Next, the sheet temperature detecting section 340 receives the detection signals of the temperature sensor 114 and the temperature sensor 115, respectively, to detect the sheet temperatures Th1 and Th2 (step S104). The calculating unit 350 calculates the temperature difference Δ Th1 by subtracting the predicted temperature Th1 'from the sheet temperature Th1, and calculates the temperature difference Δ Th2 by subtracting the predicted temperature Th2' from the sheet temperature Th2 (step S105).
The determination unit 360 determines whether or not each of the temperature differences Δ Th1 and Δ Th2 is greater than a specific threshold value T1 (step S106). When the determination unit 360 determines that the temperature difference Δ Th1 and the temperature difference Δ Th2 are greater than the specific threshold value T1 (yes in step S106), the operation control unit 370 increases the current carrying rate E1 by the specific current carrying rate (step S107).
When the energization rate E1 is changed in step S107, the process returns to step S101 after a lapse of a predetermined time, and the automatic temperature control is repeated again. The specific time is a time (for example, ten minutes) until the current-carrying rate E1 after the change reaches the predicted temperature Th1 '(predicted temperature Th 2') plus a time (for example, five minutes) until the temperature change in the state in which the posture of the pet is changed is reflected to the thin portion 102a. In step S107, the changed power supply rate E1 is stored in the storage unit 302 in association with the change time and date.
In the determination unit 360, it is not determined whether the temperature difference Δ Th1 and the temperature difference Δ Th2 are both equal to or greater than the specific threshold value T1 (no in step S106), and the determination unit 360 determines whether the temperature difference Δ Th1 is equal to or less than the specific threshold value T1 and whether the temperature difference Δ Th2 is greater than the specific threshold value T1 (step S108). When the determination unit 360 determines that the temperature difference Δ Th1 is equal to or less than the specific threshold value T1 and the temperature difference Δ Th2 is greater than the specific threshold value T1 (yes in step S108), the operation control unit 370 decreases the current carrying rate E1 by the specific current carrying rate (step S109).
When the energization rate E1 is changed in step S109, the process returns to step S101 after a lapse of a predetermined time, and the automatic temperature control is repeated again. The specific time is a time (for example, ten minutes) until the current application rate E1 after the change reaches the predicted temperature Th1 '(predicted temperature Th 2') plus a time (for example, five minutes) until the temperature change in the state where the pet has changed the posture is reflected to the sheet portion 102a. In step S109, the changed power supply rate E1 is stored in the storage unit 302 in association with the change time and date.
When the determination unit 360 does not determine that the temperature difference Δ Th1 is equal to or less than the specific threshold value T1 and the temperature difference Δ Th2 is greater than the specific threshold value T1 (no in step S108), the operation control unit 370 maintains the energization rate E1 (step S110).
If the energization rate E1 is maintained in step S110, the process returns to step S101 after a lapse of a predetermined time, and the automatic temperature control is repeated again. The specific time is a time (for example, five minutes) until the temperature change in the state where the pet has changed posture is reflected to the thin portion 102a. In step S110, the power supply rate E1 is stored in the storage unit 302 in association with the maintained time and date.
In this manner, the control unit 300 controls the temperature adjustment unit based on the result of the presence or absence of the object (pet) in each region. In the present embodiment, the sensor unit is composed of a plurality of temperature sensors that detect the temperature of each region of the sheet portion 102a. The control unit 300 detects the presence or absence of the object (pet) based on a temperature difference between the detected temperature of the temperature sensor and the predicted temperature of the position where the temperature sensor is disposed in a state where the object (pet) is absent, for each of the regions. Specifically, it is determined whether or not the temperature difference between the detected temperature and the predicted temperature is within a specific threshold value, thereby detecting the presence or absence of the object (pet). Then, the posture of the pet is determined based on the result (determination result) of the presence or absence of the object (pet) in each region, and the temperature adjustment unit is controlled. Thus, even if the temperature of the object (pet) that feels comfortable changes due to changes in the external environment (temperature, humidity, etc.), individual differences or types of the object (pet), changes in the physical condition of the object (pet), etc., the temperature of the thin portion 102a can be adjusted to a temperature that is comfortable for the object (pet). The sensor unit is formed of a temperature sensor, but is not limited thereto. The sensor unit may be any sensor as long as it can detect the presence or absence of an object (pet), and may be, for example, at least one sensor selected from a weight sensor, a distance measuring sensor, a photoelectric sensor, and a pressure sensor.
Further, by dividing the thin portion 102a into a plurality of regions and detecting the presence or absence of an object (pet) in each region, the posture of the object (pet) on the thin portion 102a can be determined. This enables temperature adjustment based on the posture of the pet. When the sheet portion 102a is divided into a plurality of regions, the same control can be performed even in the case of operating in either the cold air mode or the warm air mode by dividing the sheet portion 102a into a region in which the temperature change due to the energization of the thermoregulator is relatively large (in the present embodiment, the region on one end side of the sheet portion 102 a) and a region in which the temperature change is relatively small even when the energization is the same (in the present embodiment, the region on the other end side of the sheet portion 102 a). Further, since the cooling mechanism or the heating mechanism as the temperature adjustment unit can be disposed so as to be concentrated on one end side, a simple structure can be provided, and reduction in manufacturing cost and improvement in long-term reliability can be achieved. Furthermore, because the pet can be controlled in the same way as the pet feels comfortable postures regardless of the cold air mode and the warm air mode, the pet feels comfortable postures in the device and moves the same all the year round, and the pressure of the pet can be relieved.
The operation control unit 370 may be configured to determine that the temperature difference Δ Th1 is larger than the specific threshold value T1 and the power supply rate E1 is maintained when the temperature difference Δ Th2 is smaller than the specific threshold value T1 only in the determination unit 360. In this case, when the determination unit 360 determines that the temperature difference Δ Th1 and the temperature difference Δ Th2 are smaller than the specific threshold value T1, the operation in the energy saving mode is performed so as to reduce the current carrying rate E1 to the specific current carrying rate (for example, 30%). Thus, the energy saving mode is set when it is determined that the pet is not at the thin section 102a, whereby power consumption can be suppressed.
In the operation in the energy saving mode, the determination unit 360 may determine the presence or absence of a pet every time a specific time elapses, and when the presence of a pet is determined, the energization rate E1 may be changed to a specific energization rate (for example, an initial energization rate) or an energization rate before switching to the energy saving mode, and the automatic temperature control shown in fig. 9 may be repeated.
The initial current carrying rate is a value set in advance by an experiment or the like, but is not limited thereto. During operation, the optimum current carrying rate for the comfort temperature zone may be extracted by automatic learning from the current carrying rate stored in the storage unit 302 (the current carrying rate with the increased determination result by the determination unit 360), and the extracted current carrying rate may be used as the initial current carrying rate for the next operation. For example, the outside air temperature Th3 and the current carrying rate E1 may be stored in the storage unit 302 each time the current carrying rate E1 is maintained, and the current carrying rate that lasts for the longest time in the current outside air temperature may be extracted from the current carrying rates stored in the storage unit 302, and this current carrying rate may be updated as the initial current carrying rate. Alternatively, the current-carrying rate that is a mode value at the current outside air temperature may be extracted from the current-carrying rates stored in the storage unit 302, and this current-carrying rate may be updated as the initial current-carrying rate. This allows the initial energization rate to be updated to the optimum energization rate that is the comfort temperature zone, and allows smooth temperature adjustment during the next operation.
The present invention is not limited to the above embodiment, and may be replaced with a configuration substantially the same as the configuration described in the above embodiment, a configuration that achieves the same operational effects, or a configuration that achieves the same object.
