Patent Document 1: Japanese Laid-Open Patent Publication No. 2005-344940

When the environment in which the refrigerator is installed is in a high-humidity environment, condensation may occur in a place where the insulation between the door and the door is poor, and in order to prevent condensation, it is necessary to energize the heater for preventing condensation. . As a result, the power consumption of the refrigerator increases.

When the environment in which the refrigerator is set is in a high temperature environment, the refrigerator is The temperature difference outside the refrigerator will become larger. Therefore, in order to keep the inside of the refrigerator low, it is necessary to accelerate the rotation speed of the compressor and improve the refrigeration capacity. As a result, the power consumption of the refrigerator increases.

In the past, in the network home appliances, the operation control was implemented only by the information of the environmental comfort lifting device. Therefore, information on the humidity and temperature around the refrigerator that is normally connected to the power supply cannot be obtained. It is difficult to find a comfortable space for the operation of the refrigerator. That is, it is impossible to prevent the periphery of the refrigerator from becoming high in humidity or high temperature. As a result, the power consumption of the refrigerator is easily increased.

The object of the present invention is to suppress power consumption of a refrigerator.

In the configuration of Fig. 5, only the communication converter 137 is provided to the user who uses the cooperative system 100, whereby the control device 141 can be manufactured inexpensively. In the configuration of Fig. 6, even if the communication parts are not mounted outside the refrigerator 101, the user can utilize the cooperation system 100.

Description of the action

After the operation of adjusting the humidity and temperature around the refrigerator 101 by the refrigerator 101 itself, the operation of the cooperative system 100 to adjust the humidity around the refrigerator 101 will be described below. In the operation of the cooperative system 100, the operation of the centralized controller 102 corresponds to the centralized control method of the present embodiment.

Here, referring to Fig. 7, an operation of the refrigerator 101 to adjust the humidity around the refrigerator 101 will be described.

In step 1, the control device 141 determines whether or not the humidity detected by the temperature sensor 134 is 80% or more. When the humidity is 80% or more, in step 2, the control device 141 drives the condensation preventing heater 136 at an energization rate of 90%. Here, the eighth graph shows the relationship between the conduction rate of the condensation preventing heater 136 and the driving timing. The electric current rate is a ratio at which the condensation prevention heater 136 is energized for a few seconds per unit time of 10 seconds. For example, if the "conduction rate is 60%", it means that the condensation prevention heater 136 is turned on for 6 seconds per unit time of 10 seconds, and 4 seconds is turned off, and such a cycle is repeated. The unit time does not have to be set to 10 seconds, and can also be set to seconds, tens of seconds or minutes.

If it is found in step 1 that the humidity is less than 80%, in step 3, the control device 141 determines whether the humidity is 60% or more. If you find humidity In 60% or more, in step 4, the control device 141 drives the condensation preventing heater 136 at a current rate of 60%. If the humidity is found to be less than 60%, in step 5, the control device 141 determines whether the humidity is 40% or more. If the humidity is found to be 40% or more, in step 6, the control device 141 drives the condensation preventing heater 136 at a current rate of 30%. If the humidity is found to be less than 40%, in step 7, the control device 141 causes the condensation preventing heater 136 to be turned off.

The number of stages and the rate of power can be changed as appropriate. That is, in Fig. 7, the determination of the humidity is performed in three stages of 80%, 60%, and 40%, but it may be further subdivided into more stages or changed into two stages. In addition, when the humidity is 80% or more, the electric conduction rate of the condensation preventing heater 136 is 90%, but the electric conduction rate may be changed, and the electric conduction rate at which the rotating partition 135 does not condense may be obtained. can.

Here, an operation of the refrigerator 101 to adjust the temperature around the refrigerator 101 will be described with reference to FIG.

In step 1, the control device 141 determines whether or not the temperature detected by the outside air temperature sensor 132 is 30 ° C or higher. If the temperature is 30 ° C or higher, in step 2, the control unit 141 operates the compressor 139 at a number of revolutions of 80 rps (number of revolutions per second). If the temperature is found to be less than 30 ° C, in step 3, the control device 141 determines whether the temperature is above 20 ° C. If the temperature is found to be 20 ° C or higher, in step 4, the control unit 141 operates the compressor 139 at a number of revolutions of 60 rps. If the temperature is found to be less than 20 ° C, in step 5, the control device 141 determines whether the temperature is above 10 ° C or higher. If the temperature is found to be 10 ° C or higher, in step 6, the control unit 141 operates the compressor 139 at a rotational speed of 40 rps. If the temperature is found to be less than 10 ° C, in step 7, the control device 141 will rotate 20 rps to operate the compressor 139.

The number of stages and the rate of power can be changed as appropriate. That is, in Fig. 9, the determination of the temperature is performed in three stages of 30 ° C, 20 ° C, and 10 ° C, but it may be further subdivided into more stages or changed into two stages. Further, when the temperature is 30 ° C or higher, the number of revolutions of the compressor 139 reaches 80 rps, but the number of revolutions may be changed as long as the number of revolutions inside the refrigerator 101 can be cooled according to the outside air temperature.

Here, the action of the cooperative system 100 to adjust the humidity around the refrigerator 101 will be described with reference to FIG.

The threshold value of the temperature can be arbitrarily set. In the present embodiment, it is set to three stages of 80%, 60%, and 40%.

In step 1, the control device 141 of the refrigerator 101 transmits the information of the humidity detected by the humidity sensor 134 to the centralized controller 102. The receiving unit 201 of the centralized controller 102 receives the information transmitted by the refrigerator 101. The control unit 202 of the centralized controller 102 determines whether or not the humidity displayed by the information received by the receiving unit 201 is 80% or more. When the humidity is found to be 80% or more, in step 2, the control unit 202 of the centralized controller 102 generates information of the next command, and activates the dehumidification operation of the air conditioner 103, the operation of the dehumidifier 104, and the operation of the ventilating fan 106, respectively. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103, the dehumidifier 104, and the ventilating fan 106.

If the humidity is found to be less than 80%, in step 3, the control unit 202 of the centralized controller 102 determines whether the humidity is 60% or more. If the humidity is found to be 60% or more, in step 4, the control unit 202 of the centralized controller 102 generates the information of the next command to activate the dehumidification operation of the air conditioner 103 and The operation of the dehumidifier 104. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the dehumidifier 104.

If the humidity is found to be less than 60%, in step 5, the control unit 202 of the centralized controller 102 determines whether the humidity is 40% or more. If the humidity is found to be 40% or more, in step 6, the control unit 202 of the centralized controller 102 generates information of the next command to start the operation of the dehumidifier 104. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the dehumidifier 104.

If the humidity is found to be less than 40%, in step 7, the control unit 202 of the centralized controller 102 does not specifically perform the control of the machine 110.

The number of stages, the combination of the operating machines 110, and the type of operation can be appropriately changed. That is, in Fig. 10, the determination of the humidity is performed in three stages of 80%, 60%, and 40%, but it may be further subdivided into more stages or changed into two stages. Further, when the humidity is 80% or more, the dehumidifying operation of the air conditioner 103, the operation of the dehumidifier 104, and the operation of the ventilating fan 106 are started, but the operation of the other device 110 may be started, as long as the machine can appropriately reduce the humidity. 110 can be. Alternatively, the operation mode of the air conditioner 103, the dehumidifier 104, or the ventilator 106 may be changed as long as it is suitable for reducing the humidity. For example, where the air conditioner 103 is already in operation, the centralized controller 102 can control the air conditioner 103 to enhance the wind speed.

In the present embodiment, the commands are transmitted from the centralized controller 102 to the respective devices 110, but the information of the humidity around the refrigerator 101 may be transmitted from the centralized controller 102 to each of the devices 110, so that each of the devices 110 determines according to its own judgment. To perform the operation of reducing the humidity.

Description of the effect

In the present embodiment, the centralized controller 102 controls the adjustment function based on the humidity detected by the sensor 130 of the refrigerator 101 to adjust the indoor temperature of the machine 110 disposed in the same room as the refrigerator 101. Therefore, it is possible to maintain a proper temperature around the refrigerator 101. Thus, the power consumption of the refrigerator 101 can be suppressed.

In the present embodiment, the refrigerator 101 and the machine 110 including the sensor 134 that can detect the humidity around the refrigerator 101 are connected to the machine 110 through the centralized controller 102 in a wired or wireless manner. When the humidity detected by the refrigerator 101 exceeds the threshold value, the machine 110 can be controlled to lower the humidity around the refrigerator 101. According to the present embodiment, when the humidity around the refrigerator 101 becomes high, the humidity around the refrigerator 101 can be lowered by the machine 110. Therefore, there is no case where the refrigerator 101 does not energize the condensation preventing heater 136. Alternatively, the conduction rate of the condensation preventing heater 136 can be lowered. Therefore, power consumption can be reduced.

The second embodiment.

Here, the difference between this and the first embodiment will be described with respect to the present embodiment.

The configuration of the cooperative system 100 of the present embodiment is the same as that of the first embodiment shown in Fig. 1.

In the present embodiment, when the humidity detected by the sensor 130 of the refrigerator 101 is above the threshold of the humidity, the centralized controller 102 consumes power of the refrigerator 101 obtained by reducing the humidity around the refrigerator 101. The amount of descent is greater than the amount of power consumed by the machine 110 obtained by using the adjustment function to reduce the humidity around at least the refrigerator 101 in the room, and the machine 110 is instructed to use the adjustment function to reduce the humidity around at least the refrigerator 101 in the room.

The configuration of the centralized controller 102 is the same as that of the first embodiment shown in Fig. 2 .

In the present embodiment, when the humidity displayed by the information received by the receiving unit 201 is greater than the threshold value of the humidity, the control unit 202 reduces the power consumption of the refrigerator 101 by reducing the humidity around the refrigerator 101. The amount of decrease is greater than the amount of power consumed by the machine 110 obtained by reducing the humidity around the refrigerator 101 in the room by using the adjustment function, and the next command information is generated to lower the humidity around the refrigerator 101 in the room. The control unit 202 adjusts the amount of power consumption of the refrigerator 101 obtained by reducing the humidity around the refrigerator 101 when the humidity displayed by the information received by the receiving unit 201 is equal to or higher than the humidity threshold. The function lowers the amount of power consumed by the machine 110 obtained by at least the humidity around the refrigerator 101 in the room, and does not generate a command to lower the humidity around the refrigerator 101 in the room.

In the present embodiment, the amount of decrease in the power consumption of the refrigerator 101 obtained by lowering the humidity around the refrigerator 101 is compared with the amount of power consumed by the control device 110 to lower the humidity. Then, the machine 110 is controlled only when the amount of decrease in power consumption of the refrigerator 101 is large. Therefore, the entire cooperative system 100 can reduce the amount of power consumed.

The third embodiment.

The structure of the system of the present embodiment, the operation of the system of the present embodiment, and the effects of the present embodiment will be described in order. Here, the difference from the first embodiment will be mainly described.

In this embodiment, the centralized controller 102 is in the refrigerator 101. When the temperature detected by the sensor 130 is above the threshold of temperature, the machine 110 is commanded to use an adjustment machine to lower the temperature of at least the refrigerator 101 in the room.

In the present embodiment, the centralized controller 102 performs two or more stages of determination of the temperature detected by the sensor 130 of the refrigerator 101. The centralized controller 102 controls the adjustment functions of several different stages of the machine 110 between the plurality of machines 110. That is, in the present embodiment, the threshold value of the temperature is set to two or more stages. The adjustment function of which machine 110 the centralized controller 102 controls is determined based on which stage of the temperature detected by the sensor 130 of the refrigerator 101 is above the threshold.

The configuration of the centralized controller 102 is the same as that of the first embodiment shown in Fig. 2 .

In the present embodiment, when the temperature displayed by the information received by the receiving unit 201 is equal to or higher than the temperature threshold, the control unit 202 generates information of the next command to lower the temperature around the refrigerator 101 in the room.

Description of the action

In the operation of the cooperative system 100, the operation of the centralized controller 102 corresponds to the centralized control method of the present embodiment.

The threshold value of the temperature can be arbitrarily set, and in the present embodiment, it is set to two stages of 30 ° C and 20 ° C.

In step 1, the control device 141 of the refrigerator 101 transmits the information of the temperature detected by the outside air temperature sensor 132 to the centralized controller 102. The receiving unit 201 of the centralized controller 102 receives the information transmitted from the refrigerator 101. The control unit 202 of the centralized controller 102 receives the received by the receiving unit 201. Whether the temperature indicated by the information is above 30 °C. When the temperature is 30 ° C or higher, in step 2, the control unit 202 of the centralized controller 102 generates information of the next command, and starts the operation of the cold room of the air conditioner 103 and the operation of the ventilating fan 106, respectively. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the ventilating fan 106.

If the temperature is found to be less than 30 ° C, in step 3, the control unit 202 of the centralized controller 102 determines whether the temperature is 20 ° C or higher. If the temperature is found to be 20 ° C or higher, in step 4, the control unit 202 of the centralized controller 102 generates the information of the next command, and starts the cold room operation of the air conditioner 103, respectively. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103.

If the temperature is found to be less than 20 ° C, in step 5, the control unit 202 of the centralized controller 102 does not perform the control of the machine 110.

The number of stages, the combination of the operating machines 110, and the type of operation can be appropriately changed. That is, in Fig. 11, the determination of the temperature is performed in two stages of 30 ° C and 20 ° C, but it may be further subdivided into more stages. Further, when the temperature is 30 ° C or higher, the operation of the cold room of the air conditioner 103 and the operation of the ventilating fan 106 are started, but the operation of the other device 110 may be started, as long as the device 110 can appropriately reduce the temperature.

The fourth embodiment type.

Here, for the present embodiment, the difference between the third embodiment and the third embodiment will be mainly described.

The configuration of the cooperative system 100 of the present embodiment is the same as that of the first embodiment shown in Fig. 1.

In the present embodiment, when the temperature detected by the sensor 130 of the refrigerator 101 is above the threshold of the temperature, the centralized controller 102 consumes power of the refrigerator 101 obtained by lowering the temperature around the refrigerator 101. The amount of drop is greater than that obtained by using an adjustment function to reduce the temperature around at least the refrigerator 101 in the room. The amount of power consumed by the machine 110 instructs the machine 110 to use the adjustment function to reduce the temperature around at least the refrigerator 101 in the room.

The configuration of the centralized controller 102 is the same as that of the first embodiment shown in Fig. 2 .

In the present embodiment, when the temperature displayed by the information received by the receiving unit 201 is greater than the temperature threshold, the control unit 202 reduces the power consumption of the refrigerator 101 by lowering the temperature around the refrigerator 101. The amount of decrease is greater than the amount of power consumed by the machine 110 obtained by reducing the temperature of at least the refrigerator 101 in the room by using the adjustment function, and the information of the next command is generated to lower the temperature around the refrigerator 101 in the room. The control unit 202 adjusts the amount of power consumption of the refrigerator 101 obtained by lowering the temperature around the refrigerator 101 when the temperature displayed by the information received by the receiving unit 201 is equal to or higher than the temperature threshold. The function reduces the amount of power consumed by the machine 110 obtained by the temperature of at least the refrigerator 101 in the room, and does not generate information of the command to lower the temperature around the refrigerator 101 at least around the room.

In the present embodiment, the amount of decrease in the power consumption of the refrigerator 101 obtained by lowering the temperature around the refrigerator 101 is compared with the amount of power consumed by the control device 110 to lower the temperature. Then, the machine 110 is controlled only when the amount of decrease in power consumption of the refrigerator 101 is large. Therefore, the entire cooperative system 100 can reduce the amount of power consumed.

In Fig. 13, the average value per hour is the memory in one day, and the average value per 30 minutes or the average value of 2 hours can be memorized. The average value can also be 2 days or 1 week. The weight of the. The unit and range for storing the humidity and temperature should be determined in accordance with the capacity of the memory unit 204. Further, instead of using an average value, other statistical values such as a central value, a minimum value, and a maximum value may be used for the memory.

Next, the operation of the cooperation system 100 will be described with reference to Fig. 14. Among the operations of the cooperative system 100, the operation of the centralized controller 102 corresponds to the centralized control method of the present embodiment.

The reference value of the humidity can be arbitrarily determined, but in the present embodiment, it is the second highest humidity among the humidity in each period of one day. That is, in the present embodiment, the period in which the humidity is the highest is the period in which the humidity is higher than the reference value of the humidity.

The reference value of the temperature can be arbitrarily determined, but in the present embodiment, it is 1 The second highest temperature in the temperature of each period of the day. That is, in the present embodiment, the period in which the temperature is the highest is the period in which the temperature is higher than the reference value of the temperature.

In step 1, the control unit 202 of the centralized controller 102 determines whether or not the current time is one hour before the high humidity period. If it is found that the current time is one hour before the high humidity period, in step 2, the control unit 202 of the centralized controller 102 executes whether or not the current time is one hour before the high temperature period. If it is found that the current time is 1 hour before the high temperature period, in step 3, the control unit 202 of the centralized controller 102 generates the information of the next command, respectively starting the cold room operation of the air conditioner 103, the operation of the dehumidifier 104, and the ventilation fan.

The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103, the dehumidifier 104, and the ventilating fan 106.

If it is found that the current time is one hour before the high temperature period, in step 4, the control unit 202 of the centralized controller 102 generates the information of the next command, and activates the dehumidification operation of the air conditioner 103 and the operation of the dehumidifier 104, respectively. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the dehumidifier 104.

If it is found in step 1 that the current time is one hour before the high humidity period, in step 5, the control unit 202 of the centralized controller 102 determines whether the current time is one hour before the high temperature period. If it is found that the current time is one hour before the high temperature period, in step 6, the control unit 202 of the centralized controller 102 generates the information of the next command to activate the cold room operation of the air conditioner 103 and the operation of the ventilating fan 106, respectively. The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the ventilating fan 106.

The combination of the operating machine 110 and the type of operation can be appropriately changed. In Fig. 14, when the time comes one hour before the high humidity period, the cold room operation of the air conditioner 103, the operation of the dehumidifier 104, and the operation of the ventilating fan 106 are started, but the operation of the other machine 110 can be started. As long as it is a machine 110 that can appropriately reduce the humidity and temperature. Alternatively, the operation mode of the air conditioner 103 or the dehumidifier 104 or the ventilating fan 106 may be changed as long as the humidity and the temperature can be appropriately lowered.

In the present embodiment, the memory unit 204 is included in the centralized controller 102, but the memory unit 204 may also be included in the refrigerator 101. In this case, the control device 141 of the refrigerator 101 can predict the period in which the humidity and the temperature become high, and transmit the information of the time period to the centralized controller 102.

In the present embodiment, the commands are transmitted from the centralized controller 102 to the respective devices 110. However, the information of the high-humidity period and the high-temperature period may be transmitted from the centralized controller 102 to the respective machines 110, so that the respective machines 110 are The operation of lowering the humidity and temperature is performed by its own judgment.

In the operation of the cooperative system 100, the operation of the centralized controller 102 corresponds to the centralized control method of the present embodiment.

The threshold value of the humidity difference can be arbitrarily set, but in the present embodiment, it is set to two stages of 30% and 20%.

The threshold value of the temperature difference can also be arbitrarily set. However, in the present embodiment, the two stages of 10 ° C and 5 ° C are set.

In step 1, the control device 141 of the refrigerator 101 transmits the humidity detected by the humidity sensor 134 and the temperature detected by the external air temperature sensor 132 to the centralized controller 102. At the same time, the air conditioner 103 also transmits the humidity detected by the humidity sensor 301 and the temperature detected by the temperature sensor 302 to the centralized controller 102. The receiving unit 201 of the centralized controller 102 receives the information transmitted from the refrigerator 101 and the information transmitted from the air conditioner 103. The control unit 202 of the centralized controller 102 determines whether or not the difference in humidity displayed by the information received by the receiving unit 201 is 30% or more or whether the difference in temperature indicated by the information is 10° C. or higher.

The communication unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103, the air cleaner 105, and the ventilating fan 106. If it is found that the difference in humidity is less than 30% and the difference in temperature is less than 10 ° C, in step 3, the control unit 202 of the centralized controller 102 determines whether the difference in humidity is 20% or more or whether the difference in temperature is 5 ° C or more. .

The number of stages, the combination of the operating machines 110, and the type of operation can be appropriately changed. That is, in Fig. 16, the determination of the humidity and the temperature is performed in two stages, but it may be further subdivided into more stages. Further, the conditions of humidity and temperature are freely combined. For example, if the humidity is found to be 80% or more, only the difference in humidity is determined, and if the humidity is found to be less than 80%, both the humidity and the temperature are determined. Further, when the difference in humidity is 30% or more or the difference in temperature is 10° C. or higher, the air blowing operation of the air conditioner 103, the operation of the air cleaner 105, and the operation of the ventilating fan 106 are started, but the operation of the other machine 110 may be started.

Alternatively, the operation mode of the air conditioner 103 or the air cleaner 105 or the ventilator 106 may be changed as long as it is a type in which the humidity difference and the temperature difference can be reduced or the humidity difference and the temperature difference can be eliminated. For example, in a case where the air conditioner 103 is already in operation, the centralized controller 102 either controls the air conditioner 103 to increase the air volume, or controls the air conditioner 103 to change the wind direction to the wind direction of the air convection in the room.

In the present embodiment, the commands are transmitted from the centralized controller 102 to the respective machines 110, but only the information about the humidity and temperature around the refrigerator 101 and the surroundings of the air conditioner 103 can be transmitted from the centralized controller 102 to each of the machines 110. The information on the humidity and temperature causes each machine 110 to perform operations for reducing or eliminating the difference in humidity and temperature difference according to its own judgment.
