[0047] (Structure of storage)

[0048] Next, the structure of the storage 110 of the refrigeratory 100 of Embodiment 1 will be described with reference to Figures 1 to 5

[0049] Figure 3 is a perspective view schematically showing the outline structure of the storage of the refrigeratory shown in Figure 1 Figure 4 is an expanded view schematically showing the outline structure of the storage of the refrigeratory shown in Figure 1 Figure 5 is a sectional view schematically showing the outline structure of the storage of the refrigeratory shown in Figure 1

[0050] In addition, in Figs. 1 to 3, the upward and downward direction, the front and rear direction, and the left and right direction of the storage are shown as the upward and downward direction, the front and rear direction, and the left and right direction in the figures. Figure 3 Figure 4 As shown in Figs. 1 to 3, the storage 110 includes a box-shaped storage main body 111, a first cover member 112, a housing member 113, a mounting member 114, a fan 115, a plate-shaped first member 116, a second cover member 117, and a controller 120. In addition, the storage 110 has a power receiving device, a temperature sensor 118, a communicator, and the like. Further, the storage 110 can have a humidity sensor.

[0051] Figures 1 to 5

[0052] ​​​​​​​The power receiving device receives power supplied from the power supply device 50, and can use a publicly known wireless power receiving device. The communicator can communicate with a portable terminal (smartphone, mobile phone, or tablet), and display the environmental conditions (temperature information, humidity information, etc.) in the storage 110 on a display provided in the portable terminal, the left door 2A of the refrigeration chamber, or the right door 2B of the refrigeration chamber.

[0053] In addition, the refrigeration chamber 100 of the present embodiment 1 is configured so that the temperature and humidity in the storage 110 can be set (adjusted) by operating a display (hereinafter sometimes referred to as an operator) provided in the portable terminal, the left door 2A of the refrigeration chamber, or the right door 2B of the refrigeration chamber.

[0054] The storage main body 111 is configured of a member such as a resin having high heat insulation. A first opening portion 111A is formed on the upper surface of the storage main body 111. A first member 116 is disposed so as to cover the first opening portion 111A. The first member 116 is configured of a member having higher thermal conductivity than the storage main body 111, and can be configured of a metal such as aluminum, for example.

[0055] In addition, a second opening portion 111B is formed on the front surface of the storage main body 111. The first cover member 112 covers (covers up) the second opening portion 111B by moving in the front-rear direction.

[0056] A handle 112A is provided on the front surface of the first cover member 112. In addition, a storage member 113 is provided on the rear surface of the first cover member 112. The storage member 113 is formed in a box shape with the top surface open. Thus, food such as wine, chocolate, coffee beans, and bread can be stored in the storage member 113.

[0057] Furthermore, a protrusion portion 111C is formed on the lower portion of the rear surface of the storage main body 111 so as to protrude toward the rear. A plate-shaped mounting member 114 is placed on the upper surface of the protrusion portion 111C.

[0058] A stepped recess portion 114A is provided on the rear surface of the mounting member 114 on the right side. A fan (temperature adjuster) 115 is provided in the recess portion 114A. As the fan 115, a fan can be used, for example.

[0059] A groove 114B extending in the up-down direction is formed on the front surface of the mounting member 114 so as to communicate with the recess portion 114A. In addition, a groove 111D extending in the up-down direction is formed on the rear surface of the storage main body 111 so as to communicate with the groove 114B. The cold air supply flow path 121 is configured of the recess portion 114A, the groove 114B, and the groove 111D.

[0060] In addition, on the front surface of the mounting member 114, a substantially L-shaped groove 114C is formed on the left side. On the rear surface of the storage main body 111, a substantially L-shaped groove 111E is formed in a manner so as to communicate with the groove 114C. The groove 114C and the groove 111E constitute a cool air discharge flow path 122.

[0061] On the upper surface of the first member 116, a plate-shaped second cover member 117 is placed. On the lower surface of the second cover member 117, a substantially U-shaped groove is formed, which constitutes a cooling flow path 117A. The cooling flow path 117A is formed so that one end portion 117B communicates with the cool air supply flow path 121 and the other end portion 117C communicates with the cool air discharge flow path 122.

[0062] Thus, by the operation (work) of the fan 115, cool air in the refrigerator main body 1 can flow through the cool air supply flow path 121, the cooling flow path 117A, and the cool air discharge flow path 122, and indirectly cool the internal space of the storage main body 111 through the first member 116.

[0063] In addition, in the present embodiment 1, at least one of the cool air supply flow path 121, the cooling flow path 117A, the cool air discharge flow path 122, the first member 116, and the fan 115 constitutes a cooling portion.

[0064] The controller 120 causes the fan 115 to work in accordance with the temperature information detected by the temperature sensor 118, and adjusts the temperature in the storage main body 111. The controller 120 can be constituted by a microcomputer, an MPU, a PLC (Programmable Logic Controller), a logic circuit, or the like.

[0065] In addition, the controller 120 has an arithmetic processor and a memory. As the arithmetic processor, a CPU or the like can be used, and as the memory, a ROM, a RAM, or the like can be used.

[0066] (Action and effect of the refrigerator)

[0067] Next, the operation (temperature adjustment operation) of the storage 110 of the refrigerator 100 of the present embodiment 1 and the effect thereof will be described with reference to Figures 1 to 6 The operation (temperature adjustment operation) of the storage 110 of the refrigerator 100 of the present embodiment 1 and the effect thereof will be described with reference to

[0068] Figure 6 is a flowchart showing an example of the operation of the storage in the refrigerator of the present embodiment 1.

[0069] First, the user of the refrigerator 100 (the storage 110) operates an operator to set the temperature in the storage 110.

[0070] Thus, the set temperature information (hereinafter sometimes referred to as set temperature information) is input from the operator to the controller 120 via the communicator, and the controller 120 acquires the set temperature information (step S101). Also, the controller 120 acquires the temperature information in the storage 110 from the temperature sensor 118 (step S102).

[0071] Next, the controller 120 determines whether the temperature in the storage 110 acquired in step S102 is outside a predetermined range set in advance (step S103). Here, the predetermined range can be set by experiment or the like, and for example, can be ±0.5°C.

[0072] In a case where the controller 120 determines that the temperature in the storage 110 acquired in step S102 is not outside the predetermined range (NO in step S103), the present routine ends. On the other hand, in a case where the controller 120 determines that the temperature in the storage 110 acquired in step S102 is outside the predetermined range (YES in step S103), the processing of step S104 is implemented.

[0073] In step S104, the controller 120 determines whether the set temperature acquired in step S101 is lower than the temperature in the storage 110 acquired in step S102. In a case where the controller 120 determines that the set temperature acquired in step S101 is higher than the temperature in the storage 110 acquired in step S102 (NO in step S104), the present routine ends.

[0074] On the other hand, in a case where the controller 120 determines that the set temperature acquired in step S101 is lower than the temperature in the storage 110 acquired in step S102 (YES in step S104), the blower 115 is operated (step S105), and the processing returns to step S101.

[0075] The controller 120 repeats the processing of steps S101 to S105 until it determines that the temperature in the storage 110 acquired in step S102 is not outside the predetermined range. In addition, when the controller 120 determines that the temperature in the storage 110 acquired in step S102 is not outside the predetermined range (NO in step S103), the blower 115 is stopped, and the present routine ends.

[0076] In the refrigerator 100 of the present embodiment 1 thus configured, by the operation of the blower 115, the cool air in the refrigerator main body 1 flows through the cool air supply flow path 121, the cooling flow path 117A, and the cool air discharge flow path 122. Thereby, it is possible to indirectly cool the internal space of the storage main body 111 with the cool air in the refrigerator main body 1.

[0077] In addition, in Embodiment 1, the power supply device 50 is provided on the lower portion of the left side surface of the refrigerator main body 1, but the power supply device 50 can be provided on the lower portion of the right side surface of the refrigerator main body 1. In this case, the positioner 60 is also provided on the right side of the bottom surface of the refrigerator main body 1.

[0078] (Embodiment 2)

[0079] The refrigerator of Embodiment 2 is the refrigerator of Embodiment 1 in which the temperature regulator is constituted by a heater that heats the internal space of the storage main body.

[0080] In addition, the refrigerator of Embodiment 2 can be configured such that the storage includes a temperature detector that detects the temperature of the internal space of the storage main body, and a controller that controls the temperature regulator in accordance with the temperature detected by the temperature detector.

[0081] Hereinafter, one example of the refrigerator of Embodiment 2 will be described in detail with reference to Figure 7 and Figure 8 .

[0082] (Structure of Refrigerator)

[0083] Figure 7 is a cross-sectional view schematically showing the general structure of the storage of the refrigerator of Embodiment 2.

[0084] As shown in Figure 7 , the basic structure of the refrigerator 100 of Embodiment 2 is the same as that of the refrigerator 100 of Embodiment 1, except that the storage 110 further includes a heater (temperature regulator) 119.

[0085] The heater 119 can heat the internal space of the storage main body 111, and various heaters can be used, for example. In addition, the heater 119 is disposed between the upper surface of the storage main body 111 and the lower surface of the housing member 113. In addition, the heater 119 is supplied with electric power from the power receiving device.

[0086] (Action and Effect of Refrigerator)

[0087] Next, the action (temperature regulating action) of the storage 110 in the refrigerator 100 of Embodiment 2 and the effect thereof will be described with reference to Figure 7 and Figure 8 . In addition, the following actions are executed by the arithmetic processor of the controller 120 of the refrigerator 100 reading a program saved in the memory.

[0088] Figure 8 is a flowchart showing one example of the action of the storage in the refrigerator of Embodiment 2.

[0089] First, the user of the refrigerator 100 (the storage 110) operates the operator to set the temperature within the storage 110.

[0090] Then, the set temperature information (hereinafter sometimes referred to as set temperature information) is input from the operator to the controller 120 via the communicator, and the controller 120 acquires (obtains) the set temperature information (step S201). Also, the controller 120 acquires the temperature information within the storage 110 from the temperature sensor 118 (step S202).

[0091] Next, the controller 120 determines whether the temperature within the storage 110 acquired in step S202 is outside a predetermined range set in advance (step S203). Here, the predetermined range can be set by experiment or the like, and for example, can be ±0.5°C.

[0092] The controller 120 ends the present routine in a case where it is determined that the temperature within the storage 110 acquired in step S202 is not outside the predetermined range (NO in step S203). On the other hand, the controller 120 performs the processing of step S204 in a case where it is determined that the temperature within the storage 110 acquired in step S202 is outside the predetermined range (YES in step S203).

[0093] In step S204, the controller 120 determines whether the set temperature acquired in step S201 is lower than the temperature within the storage 110 acquired in step S202. The controller 120 causes the fan 115 to operate (step S205) in a case where it is determined that the set temperature acquired in step S201 is lower than the temperature within the storage 110 acquired in step S202 (YES in step S204), and returns to the processing of step S201.

[0094] On the other hand, the controller 120 causes the heater 119 to operate (step S206) in a case where it is determined that the set temperature acquired in step S201 is higher than the temperature within the storage 110 acquired in step S202 (NO in step S204), and returns to the processing of step S201.

[0095] The controller 120 repeatedly performs the processing of steps S201 to S206 until it is determined that the temperature within the storage 110 acquired in step S202 is not outside the predetermined range. Also, the controller 120 stops the fan 115 and / or the heater 119 when it is determined that the temperature within the storage 110 acquired in step S202 is not outside the predetermined range (NO in step S203), and ends the present routine.

[0096] The cooler 100 of Embodiment 2 thus configured also exhibits the same operational effects as the cooler 100 of Embodiment 1.

[0097] Numerous modifications and other embodiments of the present application are apparent to those skilled in the art in view of the foregoing description. Therefore, the description should not be construed as limiting the application but merely as exemplifying the various aspects. The detailed description excludes any specific details introduced only by way of example and for purposes of illustration. Furthermore, the purpose of the foregoing description is to teach any person skilled in the art to make and use the application.
