Description

  The present invention relates to a linkage system, a centralized controller, and a centralized control method. The present invention relates to a cooperation system in which, for example, a refrigerator and devices other than the refrigerator are connected via a centralized controller.

  In recent years, networking of household electrical devices has been promoted.

  2. Description of the Related Art Conventionally, there are network home appliances connected so that a plurality of environmental comfort devices can communicate with each other (see, for example, Patent Document 1). Air conditioners, humidifiers, dehumidifiers, and air purifiers are environmental comfort devices. The refrigerator is not an environmentally comfortable device.

JP 2005-344940 A Japanese Patent Laid-Open No. 2008-075918 JP 2003-148856 A JP 2014-020715 A JP 2009-236484 A JP 2013-130384 A JP 2001-235215 A JP 2002-022342 A JP-A-11-166784

  When the environment where the refrigerator is installed is highly humid, it is necessary to energize the heater for preventing dew condensation in order to prevent dew condensation on places with relatively low heat insulation performance such as the partition between doors. There is. As a result, the power consumption of the refrigerator increases.

  When the environment where the refrigerator is installed is high temperature, the temperature difference between inside and outside the refrigerator becomes large. Therefore, in order to keep the inside of the refrigerator at a low temperature, it is necessary to increase the rotation speed of the compressor and increase the refrigerating capacity. As a result, the power consumption of the refrigerator increases.

  In conventional network home appliances, driving control is performed using information only from environmental comfort devices. Therefore, it is impossible to obtain information on the humidity and temperature around the refrigerator where the power is always on. It is difficult to create a comfortable space for the operation of the refrigerator. That is, it cannot prevent the periphery of the refrigerator from becoming high humidity or high temperature. Therefore, the power consumption of the refrigerator tends to increase.

  An object of this invention is to suppress the power consumption of the refrigerator in a home.

A cooperation system according to one aspect of the present invention includes:
A refrigerator in the home having a sensor for detecting the temperature around the refrigerator;
Having an adjustment function of adjusting the temperature in the room, equipment installed in the same room as the refrigerator,
A centralized controller that controls the adjustment function of the device according to the temperature detected by the sensor of the refrigerator.

  In the present invention, the centralized controller controls an adjustment function for adjusting the indoor temperature of a device installed in the same room as the refrigerator, according to the temperature detected by the sensor of the refrigerator in the home. For this reason, the refrigerator periphery can be maintained at an appropriate temperature. Therefore, the power consumption of the refrigerator in the home can be suppressed.

*** Explanation of operation ***
Hereinafter, after the operation of the refrigerator 101 itself adjusting the humidity and temperature around the refrigerator 101 is described, the operation of the cooperation system 100 adjusting the humidity around the refrigerator 101 will be described. Of the operations of the cooperation system 100, the operation of the centralized controller 102 corresponds to the centralized control method according to the present embodiment.

  With reference to FIG. 7, the operation of the refrigerator 101 for adjusting the humidity around the refrigerator 101 will be described.

  In step 1, the control device 141 determines whether the humidity detected by the humidity sensor 134 is 80% or more. If the humidity is 80% or more, in step 2, the control device 141 drives the dew condensation prevention heater 136 at an energization rate of 90%. FIG. 8 shows the relationship between the energization rate of the dew condensation prevention heater 136 and the drive timing. The energization rate is a ratio indicating how many seconds the unit for dew condensation prevention 136 is energized per 10 seconds. For example, when the “energization rate is 60%”, a cycle in which the condensation prevention heater 136 is turned on for 6 seconds per 10 seconds and turned off for 4 seconds is repeatedly performed. The unit time is not limited to 10 seconds, but may be several seconds, several tens of seconds, or several minutes.

  When the humidity is less than 80% in Step 1, in Step 3, the control device 141 determines whether the humidity is 60% or more. If the humidity is 60% or higher, in step 4, the control device 141 drives the dew condensation prevention heater 136 at an energization rate of 60%. If the humidity is less than 60%, in step 5, the control device 141 determines whether the humidity is 40% or more. If the humidity is 40% or higher, in step 6, the control device 141 drives the dew condensation prevention heater 136 at an energization rate of 30%. If the humidity is less than 40%, in step 7, the control device 141 turns off the dew condensation prevention heater 136.

  The number of steps and the energization rate can be changed as appropriate. That is, in FIG. 7, the determination of humidity is performed in three stages of 80%, 60%, and 40%, but the stages may be further divided or may be changed to two stages. Further, for example, when the humidity is 80% or more, the energization rate of the dew condensation prevention heater 136 is 90%, but the energization rate is changed if the energization rate is such that the rotating partition plate 135 does not dew. You can do it.

  With reference to FIG. 9, the operation | movement in which the refrigerator 101 adjusts the temperature of the refrigerator 101 periphery is demonstrated.

  In step 1, the control device 141 determines whether 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 device 141 operates the compressor 139 at a rotation speed of 80 rps (rotation per second). If the temperature is lower than 30 ° C, in step 3, the control device 141 determines whether the temperature is 20 ° C or higher. If the temperature is 20 ° C. or higher, in step 4, the controller 141 operates the compressor 139 at a rotational speed of 60 rps. If the temperature is lower than 20 ° C, in step 5, the control device 141 determines whether the temperature is 10 ° C or higher. If the temperature is 10 ° C. or higher, in step 6, the controller 141 operates the compressor 139 at a rotational speed of 40 rps. If the temperature is less than 10 ° C., in step 7, the controller 141 operates the compressor 139 at a rotation speed of 20 rps.

  The number of steps and the number of rotations can be changed as appropriate. That is, in FIG. 9, the temperature determination is performed in three stages of 30 ° C., 20 ° C., and 10 ° C., but the stages may be further divided or may be changed to two stages. For example, when the temperature is 30 ° C. or higher, the rotational speed of the compressor 139 is 80 rps. However, if the rotational speed can cool the inside of the refrigerator 101 according to the outside air temperature, the rotational speed is changed. Good.

  With reference to FIG. 10, the operation | movement which the cooperation system 100 adjusts the humidity around the refrigerator 101 is demonstrated.

  The humidity threshold can be set arbitrarily, but in this embodiment, it is set in three stages of 80%, 60%, and 40%.

  In step 1, the control device 141 of the refrigerator 101 transmits information on the humidity detected by the humidity sensor 134 to the centralized controller 102. The receiving unit 201 of the centralized controller 102 receives information transmitted from the refrigerator 101. The control unit 202 of the centralized controller 102 determines whether or not the humidity indicated by the information received by the receiving unit 201 is 80% or higher. When the humidity is 80% or more, in step 2, the control unit 202 of the centralized controller 102 generates information instructing to start the dehumidifying operation of the air conditioner 103, the operation of the dehumidifier 104, and the operation of the ventilation fan 106, respectively. To do. The transmission 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 ventilation fan 106.

  When the humidity is less than 80%, in step 3, the control unit 202 of the centralized controller 102 determines whether the humidity is 60% or more. When the humidity is 60% or more, in step 4, the control unit 202 of the centralized controller 102 generates information instructing to start the dehumidifying operation of the air conditioner 103 and the operating of the dehumidifier 104, respectively. The transmission unit 203 of the centralized controller 102 transmits information generated by the control unit 202 to the air conditioner 103 and the dehumidifier 104.

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

  When the humidity is less than 40%, the control unit 202 of the centralized controller 102 does not particularly control the device 110 in step 7.

  The number of stages, the combination of devices 110 to be operated, and the mode of operation can be changed as appropriate. That is, in FIG. 10, the determination of humidity is performed in three stages of 80%, 60%, and 40%. However, the stages may be further divided or may be changed to two stages. Also, for example, when the humidity is 80% or more, the dehumidifying operation of the air conditioner 103, the dehumidifying device 104, and the ventilation fan 106 are started. If the device 110 can appropriately reduce the humidity, The operation of another device 110 may be started. Alternatively, as long as the humidity can be appropriately reduced, the operation mode of the air conditioner 103, the dehumidifier 104, or the ventilation fan 106 may be changed. For example, when the air conditioner 103 is already in operation, the centralized controller 102 may control the air conditioner 103 so as to increase the wind speed.

  In the present embodiment, a command is transmitted from the centralized controller 102 to each device 110, but each device 110 only has to transmit information on the humidity around the refrigerator 101 to each device 110 from the centralized controller 102. You may perform the driving | operation for lowering | hanging humidity by judgment.

*** Explanation of effects ***
In the present embodiment, the centralized controller 102 controls an adjustment function for adjusting the indoor humidity of the device 110 installed in the same room as the refrigerator 101 according to the humidity detected by the sensor 130 of the refrigerator 101. . For this reason, the periphery of the refrigerator 101 can be kept at an appropriate humidity. Therefore, power consumption of the refrigerator 101 can be suppressed.

  In the present embodiment, the refrigerator 101 provided with a humidity sensor 134 that detects the humidity around the refrigerator 101 and the device 110 are connected via a centralized controller 102 in a wired or wireless manner. When the humidity detected by the refrigerator 101 exceeds the threshold, the device 110 is controlled so as to reduce 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 device 110. Therefore, the refrigerator 101 does not wastefully energize the condensation prevention heater 136. Alternatively, the energization rate of the condensation prevention heater 136 can be lowered. For this reason, power consumption can be reduced.

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  About the structure of the cooperation system 100 which concerns on this Embodiment, it is the same as the thing of Embodiment 1 shown in FIG.

  In the present embodiment, when the humidity detected by the sensor 130 of the refrigerator 101 is equal to or higher than the humidity threshold, the centralized controller 102 reduces the amount of power consumption of the refrigerator 101 obtained by reducing the humidity around the refrigerator 101. If the power consumption of the device 110 by lowering at least the humidity around the refrigerator 101 using the adjustment function is larger than the power consumption of the device 110, the humidity of the device 110 is reduced at least around the refrigerator 101 using the adjustment function. Command.

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

  In the present embodiment, the control unit 202 reduces the power consumption of the refrigerator 101 obtained by lowering the humidity around the refrigerator 101 when the humidity indicated by the information received by the receiving unit 201 is equal to or higher than the humidity threshold. However, if it is larger than the power consumption of the apparatus 110 by reducing at least the humidity around the refrigerator 101 using the adjustment function, information for instructing to reduce at least the humidity around the refrigerator 101 in the room is generated. Even when the humidity indicated by the information received by the receiving unit 201 is equal to or higher than the humidity threshold value, the control unit 202 reduces the power consumption of the refrigerator 101 obtained by lowering the humidity around the refrigerator 101. If it is less than the amount of power consumption of the device 110 by using at least the humidity around the refrigerator 101 to be used, information for instructing to reduce at least the humidity around the refrigerator 101 in the room is not generated.

  In the present embodiment, the reduction amount of power consumption of the refrigerator 101 obtained by lowering the humidity is compared with the power consumption amount necessary for controlling the device 110 so as to lower the humidity. And the apparatus 110 is controlled only when the reduction amount of the power consumption of the refrigerator 101 is large. Therefore, the power consumption can be reduced as the entire linkage system 100.

Embodiment 3 FIG.
The configuration of the system according to the present embodiment, the operation of the system according to the present embodiment, and the effects of the present embodiment will be described in order. Differences from the first embodiment will be mainly described.

*** Explanation of configuration ***
About the structure of the cooperation system 100 which concerns on this Embodiment, it is the same as the thing of Embodiment 1 shown in FIG.

  In the present embodiment, when the temperature detected by the sensor 130 of the refrigerator 101 is equal to or higher than the temperature threshold, the centralized controller 102 lowers at least the temperature around the refrigerator 101 in the room using the adjustment function for the device 110. I ordered.

  In the present embodiment, the centralized controller 102 makes a determination of two or more levels for the temperature detected by the sensor 130 of the refrigerator 101. The centralized controller 102 controls the adjustment function of a different number of devices 110 among the plurality of devices 110 for each stage. That is, in the present embodiment, the temperature threshold is set in two or more stages. Depending on which level of threshold value the temperature detected by the sensor 130 of the refrigerator 101 is above, it is determined which device 110 the central controller 102 controls.

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

  In the present embodiment, control unit 202 generates information instructing to lower at least the temperature around refrigerator 101 in the room when the temperature indicated by the information received by receiving unit 201 is equal to or higher than the temperature threshold.

*** Explanation of operation ***
With reference to FIG. 11, the operation | movement which the cooperation system 100 adjusts the temperature of the refrigerator 101 periphery is demonstrated. Of the operations of the cooperation system 100, the operation of the centralized controller 102 corresponds to the centralized control method according to the present embodiment.

  The temperature threshold can be set arbitrarily, but in this embodiment, it is set in two stages of 30 ° C. and 20 ° C.

  In step 1, the control device 141 of the refrigerator 101 transmits information on 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 information transmitted from the refrigerator 101. The control unit 202 of the centralized controller 102 determines whether the temperature indicated by the information received by the receiving unit 201 is 30 ° C. or higher. When the temperature is 30 ° C. or higher, in step 2, the control unit 202 of the centralized controller 102 generates information instructing to start the cooling operation of the air conditioner 103 and the operation of the ventilation fan 106, respectively. The transmission unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the ventilation fan 106.

  When the temperature is lower than 30 ° C., in step 3, the control unit 202 of the centralized controller 102 determines whether the temperature is 20 ° C. or higher. When the temperature is equal to or higher than 20 ° C., in step 4, the control unit 202 of the centralized controller 102 generates information instructing to start the cooling operation of the air conditioner 103. The transmission unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103.

  When the temperature is lower than 20 ° C., in step 5, the control unit 202 of the centralized controller 102 does not particularly control the device 110.

  The number of stages, the combination of devices 110 to be operated, and the mode of operation can be changed as appropriate. That is, in FIG. 11, the temperature determination is performed in two stages of 30 ° C. and 20 ° C., but the stages may be divided more finely. Further, for example, when the temperature is 30 ° C. or higher, the cooling operation of the air conditioner 103 and the operation of the ventilation fan 106 are started. You may start driving. Alternatively, the mode of operation of the air conditioner 103 or the ventilation fan 106 may be changed as long as the temperature can be appropriately lowered.

Decide on the period.

  The unit and range for storing humidity and temperature can be changed as appropriate. In FIG. 13, the average value for every hour is stored for one day, but the average value for every 30 minutes or the average value in units of two hours may be stored, or the average value for two days or You may memorize for one week. The unit and range for storing humidity and temperature are desirably determined in accordance with the capacity of the storage unit 204. Further, instead of the average value, other statistical values such as a median value, a minimum value, and a maximum value may be stored.

  Next, the operation of the cooperation system 100 will be described with reference to FIG. Of the operations of the cooperation system 100, the operation of the centralized controller 102 corresponds to the centralized control method according to the present embodiment.

  Although the reference value of humidity can be determined arbitrarily, in the present embodiment, it is the second highest humidity among the humidity in each time zone of the day. That is, in the present embodiment, the time zone in which the humidity is highest is the time zone in which the humidity is higher than the humidity reference value.

  The reference value of the temperature can also be arbitrarily determined, but in the present embodiment, it is the second highest temperature among the temperatures in each time zone of the day. That is, in the present embodiment, the time zone in which the temperature is highest is the time zone in which the temperature is higher than the temperature reference value.

  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 the current time is one hour before the high humidity period, in step 2, the control unit 202 of the centralized controller 102 determines whether the current time is one hour before the high temperature period. If the current time is one hour before the high temperature period, in step 3, the control unit 202 of the centralized controller 102 starts cooling operation of the air conditioner 103, operation of the dehumidifier 104, and operation of the ventilation fan 106, respectively. Generate information to command The transmission 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 ventilation fan 106.

  If the current time is not one hour before the high temperature period, in step 4, the control unit 202 of the centralized controller 102 instructs the dehumidifying operation of the air conditioner 103 and the dehumidifying device 104 to start. Generate information. The transmission unit 203 of the centralized controller 102 transmits information generated by the control unit 202 to the air conditioner 103 and the dehumidifier 104.

  If the current time is not one hour before the high humidity period in step 1, in step 5, the control unit 202 of the centralized controller 102 determines whether or not the current time is one hour before the high temperature period. If the current time is one hour before the high temperature period, in step 6, the control unit 202 of the centralized controller 102 commands to start the cooling operation of the air conditioner 103 and the operation of the ventilation fan 106, respectively. Is generated. The transmission unit 203 of the centralized controller 102 transmits the information generated by the control unit 202 to the air conditioner 103 and the ventilation fan 106.

  If the current time is not one hour before the high temperature period, in step 7, the control unit 202 of the centralized controller 102 does not particularly control the device 110.

In FIG. 14, for example, the cooling operation of the air conditioner 103, the operation of the dehumidifier 104, and the operation of the ventilation fan 106 are started at a time one hour before the high humidity period and one hour before the high temperature period. As long as the device 110 can appropriately reduce the humidity and temperature, the operation of another device 110 may be started. Alternatively, the operation mode of the air conditioner 103, the dehumidifier 104, or the ventilation fan 106 may be changed as long as the humidity and temperature can be appropriately reduced. For example, when the air conditioner 103 is already in operation, the centralized controller 102 may control the air conditioner 103 so as to increase the wind speed and lower the set temperature.

  In the present embodiment, the storage unit 204 is provided in the centralized controller 102, but the storage unit 204 may be provided in the refrigerator 101. In that case, the control device 141 of the refrigerator 101 predicts a time zone in which the humidity and temperature are high, and transmits the time zone information to the centralized controller 102.

*** Explanation of effects ***
In the present embodiment, the humidity and the outside temperature detected by the refrigerator 101 are stored. A time zone in which the humidity and temperature around the refrigerator 101 increase is predicted. Immediately before the time period when the humidity and temperature increase, the device 110 is controlled so as to decrease the humidity and temperature. Therefore, the energization rate of the condensation prevention heater 136 and the rotation speed of the compressor 139 can be lowered. Therefore, power consumption of the refrigerator 101 can be reduced. Moreover, the peak of humidity and temperature in one day can be lowered. Therefore, the humidity and temperature unevenness for each time zone are reduced, and a comfortable space can be created.

Of the operations of the cooperation system 100, the operation of the centralized controller 102 corresponds to the centralized control method according to the present embodiment.

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

  The threshold value of the temperature difference can also be arbitrarily set, but in this embodiment, it is set in two stages of 10 ° C. and 5 ° C.

  In step 1, the control device 141 of the refrigerator 101 transmits the humidity detected by the humidity sensor 134 and the temperature information detected by the outside air temperature sensor 132 to the centralized controller 102. At the same time, the air conditioner 103 also transmits information on 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 the humidity difference indicated by the information received by the receiving unit 201 is 30% or more, or whether the temperature difference indicated by the information is 10 ° C. or more.

Good. For example, when the air conditioner 103 is already in operation, the centralized controller 102 controls the air conditioner 103 so as to increase the air volume, or changes the wind direction to a wind direction in which room air convects. Alternatively, the air conditioner 103 may be controlled.

  In the present embodiment, a command is transmitted from the centralized controller 102 to each device 110. From the centralized controller 102, information on the humidity and temperature around the refrigerator 101 and the humidity and temperature around the air conditioner 103 are sent to each device 110.
