  However, for example, when a wine cellar is used for long-term storage of wine (around 14 ° C.), it is often transferred to a refrigerator or the like before drinking wine and cooled to a drinking temperature (around 7 ° C.). . That is, it is difficult to manage the temperature for long-term storage and the temperature for short-term storage in one wine cellar. In addition, the conventional wine cellar generally prevents the condensation of the glass door by installing a door heater. However, this door heater has a problem that power consumption increases.

  The present invention has been made in view of the above, and an object of the present invention is to provide a wine cellar that can reduce power consumption by eliminating a door heater for preventing condensation from the main body.

  In order to solve the above-described problems and achieve the object, the present invention is a wine cellar having two upper and lower storage chambers, which dissipates liquid while dissipating high-temperature and high-pressure gas refrigerant sent from a compressor in a cooling cycle. The condenser to be changed into a refrigerant is arranged so as to include the front side of the left and right side surfaces of the wine cellar body and the front side of the top surface.

  The wine cellar according to the present invention has an effect that power consumption can be kept low.

  Below, the example of the wine cellar concerning the present invention is described in detail based on a drawing. Note that the present invention is not limited to the embodiments.

  1-1 is a front view and a cross-sectional view of the wine cellar of the present embodiment, and FIG. 1-2 is a side view and a cross-sectional view of the wine cellar of the present embodiment.

  1-1 and 1-2, reference numeral 1 denotes a wine cellar. The wine cellar 1 is provided with an upper storage chamber 2a and a lower storage chamber 2b that can be individually temperature controlled. Each storage chamber is completely independent by a fixed partition plate 3, and can be set in units of 1 ° C. within a range of 5 ° C. to 20 ° C., for example. In the present embodiment, as an example, it is assumed that a wine cellar capable of storing 12 wine bottles and having a total effective upper and lower capacity of 100 L class (small size). By configuring the upper and lower chambers, more accurate temperature control becomes possible, for example, one for short-term storage (about 7-8 ° C), the other for long-term storage (about 14 ° C), etc. In addition, it is possible to use the upper and lower rooms properly according to the purpose.

  Moreover, as shown to FIGS. 1-1 and 1-2, the glass door 4 by which the full flat glass of the three-layer structure excellent in heat insulation and interior property was employ | adopted in the wine cellar 1 of a present Example. It is attached. In addition, a touch-type operation panel 5 is arranged on the upper part of the glass door 4 so that the main power supply and light (LED lighting in each storage room) can be turned on and off, the temperature can be set, and stored manually. It is possible to keep the indoor environment in an optimum state. FIG. 2 is a diagram illustrating an example of the touch-type operation panel 5. In the present embodiment, since the upper storage chamber 2a and the lower storage chamber 2b are independent, the temperature of each storage chamber can be set individually (corresponding to Upper and Lower in FIG. 2).

  In addition, as shown in the cross-sectional views of FIGS. 1-1 and 1-2, the wine cellar 1 of the present embodiment has a shelf pitch set at such a height that a thick wine bottle (champagne diameter) can be taken in and out smoothly. In the upper storage room 2a, shelves that can store three wine bottles in a laid state are provided in a vertical four-tier configuration, and a total of twelve wine bottles can be stored. Further, in the lower storage chamber 2b, three wine bottles can be diagonally arranged on the bottom shelf using a step of the storage 6 in which a compressor necessary for a cooling cycle, which will be described later, is stored. Furthermore, shelves that can store three wine bottles in a laid state are provided in a three-stage configuration vertically, and a total of twelve wine bottles can be stored. In addition, the shelf board 7 which partitions off the shelf of each preservation | save room is a structure which can be removed and attached freely by sliding. In this way, each storage room has a configuration that can store three wine bottles in one shelf, so that the installation width can be made smaller than that of a general four-type storage type, and a compressor is mounted. As a wine cellar, the minimum installation area can be realized. For example, the wine cellar 1 of the present embodiment has a main body width of 400 mm or less and a depth of 500 mm or less. In addition, if the installation area is reduced by the above configuration, the height of the main body is increased. However, for example, by placing wine for short-term storage (drinking) in the upper storage chamber 2a, the height can be increased. The wine can be taken in and out, and the wine can be taken in and out more easily than in the lower storage chamber 2b.

  Also, in the cross-sectional view of FIG. 1-2, a storage 6 having a stepped step is provided in the back of the lower storage chamber 2b, and this storage 6 is used in a cooling cycle described later. Devices such as compressors and capillary tubes are housed. A storage 8a that is a space partitioned from each storage chamber by a back panel 8b is provided at the back of each storage chamber. The storage 8a is used, for example, in a cooling cycle described later. A dryer and a cooler are accommodated, and further, a heater such as a heating heater, LED, an air circulation fan, various temperature sensors, and the like are also accommodated.

  FIG. 3 is a diagram showing the internal structure of the side surface and the top surface of the wine cellar 1. In this embodiment, with respect to the left and right side surfaces and the top surface of the wine cellar 1, the panel steel plate 9, the storage portion 10 of the condenser 33 (33 a, 33 b) to be described later, the heat insulating material 11, and the wall surface 12 of the storage room (outside box). It is structured in order. In this embodiment, the condenser 33, which is a device necessary for the cooling cycle, is distributed in a part or all of the side surface including the frontage part (front side side) and the front side, not the storage 8a. To do. Thereby, compared with the case where a capacitor | condenser is arrange | positioned in the space of a back surface, it becomes possible to make the depth dimension of the main body of the wine cellar 1 small. In addition, the conventional wine cellar generally prevents the condensation of the glass door by installing a door heater. However, the wine cellar 1 of this embodiment has a condenser 33 used for the cooling cycle on the left and right sides of the main body. Because it is arranged on the side and top surface, especially on the near side (glass door 4 side), heat is transferred to the glass door 4 by the heat radiation of the condenser 33, and a door heater is installed by this heat. Even without it, condensation can be prevented. Furthermore, by eliminating the door heater from the main body, it is possible to keep power consumption lower than before.

  Next, the electrical circuit configuration and control of the wine cellar 1 configured as described above will be described. FIG. 4 is a diagram illustrating an example of an electrical system diagram of the wine cellar 1.

  As shown in FIG. 4, in the wine cellar 1 of the present embodiment, the control circuit 21 receives AC 100V as input and controls the electronic devices in the wine cellar 1. That is, the LED 22 (22a, 22b), the temperature sensor 23 (23a, 23b), the defrosting temperature sensor 24 (24a, 24b), and the heating heater 25 (25a, 25b) provided for the upper storage chamber 2a and the lower storage chamber 2b, respectively. 25b), the fan 26 (26a, 26b), the compressor 31 and the electromagnetic valve (three-way valve) 32 used in the cooling cycle, and the operation panel 5 provided on the glass door 4 are individually controlled.

  In FIG. 4, LED 22a is illumination for the upper storage chamber 2a, and LED 22b is illumination for the lower storage chamber 2b, which are turned ON / OFF by the control circuit 21 in conjunction with the ON / OFF operation of the operation panel 5, respectively. Be controlled.

  The temperature sensor 23a is a sensor that detects the temperature in the upper storage chamber 2a, and the temperature sensor 23b is a sensor that detects the temperature in the lower storage chamber 2b. Notice. Upon receiving this notification, the control circuit 21 compares the temperature set by operating the operation panel 5 with the notified temperature, and performs control related to cooling and heating so that the set temperature is maintained. The defrosting temperature sensor 24a is disposed in the vicinity of the cooler for the upper storage chamber 2a, and the defrosting temperature sensor 24b is disposed in the vicinity of the cooler for the lower storage chamber 2b. For example, when the control circuit 21 periodically performs defrosting control, each defrosting temperature sensor 24a, 24b detects that the defrosting of a nearby cooler (evaporator) has been completed (temperature has increased). Notify the control circuit 21.

  The heating heater 25a is installed integrally with the cooler for the upper storage chamber 2a, and the heating heater 25b is installed integrally with the cooler for the lower storage chamber 2b. These heaters are controlled by the control circuit 21. To increase the ambient temperature. The fan 26a is installed in the upper storage chamber 2a, and the fan 26b is installed in the lower storage chamber 2b. Under the control of the control circuit 21, the air in the allocated storage chamber is circulated. For example, the temperature in the upper storage chamber 2a can be raised to a preset temperature by the heating heater 25a and the fan 26a being linked in the upper storage chamber 2a and circulating the air warmed by the heating heater 25a. . In the lower storage chamber 2b, the same control as described above can be performed. For example, when the outside air temperature is particularly low, such as a room in midwinter, the temperature in each storage room of the wine cellar 1 may be significantly lower than the set temperature. (25a, 25b) enables temperature management.

  Moreover, in FIG. 4, the control circuit 21 electrically controls the compressor 31 and the electromagnetic valve 32, and controls the cooling cycle of the wine cellar 1 of a present Example separately for every preservation | save room. FIG. 5 is a diagram showing a cooling cycle of the wine cellar 1 of the present embodiment. More specifically, two coolers 36a and 36b are assigned to the upper and lower storage chambers one by one, and the control circuit 21 is The cooling cycle of the storage chamber 2a and the cooling cycle of the lower storage chamber 2b are individually controlled.

  The compressor (compressor) 31 compresses the gas refrigerant to generate and output a high-temperature and high-pressure gas refrigerant. Here, for example, when control is performed to lower the temperature in the upper storage chamber 2a, the control circuit 21 controls the electromagnetic valve 32 so that the gas refrigerant generated by the compressor 31 is sent to the condenser (condenser) 33a. Control. The high-temperature and high-pressure gas refrigerant sent from the compressor 31 changes into a normal-temperature and high-pressure liquid refrigerant while releasing heat from the condenser 33a. The liquid refrigerant at room temperature and high pressure removes foreign substances such as moisture by the dryer 34, and then passes through the capillary tube 35a having a thin tube diameter, thereby reducing the pressure so that it is easily evaporated (vaporized). Then, the liquid refrigerant that has become low temperature and low pressure is sent to the cooler 36a, where it takes heat from the surrounding air and evaporates (vaporizes). The refrigerant that has become gas in the cooler 36 a returns to the compressor 31. By this cycle, the periphery of the cooler 36a is cooled.

  On the other hand, when performing control so as to lower the temperature in the lower storage chamber 2b, the control circuit 21 controls the electromagnetic valve 32 so that the gas refrigerant generated by the compressor 31 is sent to the condenser (condenser) 33b. The high-temperature and high-pressure gas refrigerant sent from the compressor 31 changes into a normal-temperature and high-pressure liquid refrigerant while releasing heat from the condenser 33b. The room-temperature and high-pressure liquid refrigerant removes foreign substances such as moisture by the dryer 34, and then passes through the capillary tube 35b having a thin tube diameter to reduce the pressure so that it is easily evaporated (vaporized). The liquid refrigerant that has become low temperature and low pressure is sent to the cooler 36b, where it takes heat from the surrounding air and evaporates (vaporizes). The refrigerant that has become gas in the cooler 36 b returns to the compressor 31. By this cycle, the periphery of the cooler 36b is cooled.

  In each storage room, the equipment used for the cooling cycle and the fan 26 (26a, 26b) are linked to circulate the air cooled by the coolers 36a, 36b, that is, the cold air is stored in each storage room. By being sent into the room, the temperature in each storage room can be lowered to the set temperature.

  In the cooling cycle, for convenience of explanation, the control circuit 21 alternately operates the electromagnetic valves 32. However, the present invention is not limited to this, and the cooling cycle of the upper storage chamber 2a and the cooling cycle of the lower storage chamber 2b are not limited. It is good also as adjusting the solenoid valve 32 so that it may be performed simultaneously.

  FIG. 6 is a diagram showing how air circulates in each storage room, and specifically shows how air cooled by the cooling cycle and air heated by a heating heater are circulated. . In FIG. 6, 41a is a fin type cooler for the upper storage chamber 2a in which the heating heater 25a and the cooler 36a are integrated, and 41b is the heating heater 25b and the cooler 36b. It is a fin type cooler for the lower storage chamber 2b arranged in an integrated manner. In the present embodiment, the air warmed by the fin type cooler 41 (41a, 41b) and the cooled air are circulated by the fan 26 (26a, 26b) as shown by the arrows in the figure to be preserved. The temperature set by the operation panel 5 can be maintained for each room. Further, by adopting the fin structure, the cooler itself can be downsized without lowering the cooling efficiency, so that the installation area can be further reduced. For example, as shown above, the wine cellar 1 of the present embodiment has a main body width of 400 mm or less and a depth of 500 mm or less, and the cause thereof is a shelf configuration capable of storing three wine bottles. In addition to the fact that the arrangement position of the capacitor 33 has been devised, a fin structure is employed. Thereby, while being able to make an installation area small, the operation time of a compressor can be shortened and the energy-saving effect can be acquired. In addition, the cooler adopting the fin structure is accompanied by the occurrence of condensation on the structure, but the air passing through the fin circulates while containing moisture, so that each storage chamber can be kept at high humidity.

  Moreover, as shown in FIG. 6, in the wine cellar 1 of this Embodiment, the some outdoor air exchange hole 42 is provided in the main body back surface, respectively. Thus, moisture contained in the outside air can be taken into the upper storage chamber 2a and the lower storage chamber 2b via the storage 8a and the back panel 8b, and excess water can be discharged out of the storage chamber. Therefore, it is possible to keep the humidity in each storage room at an optimum state.

  FIG. 7 is a development view of main components of the wine cellar 1 of the present embodiment. FIG. 7 shows only the main parts of the main body of the wine cellar 1 of the present embodiment, and does not display all the parts of the main body.

  As described above, in the present embodiment, the wine cellar 1 main body is configured to include two storage chambers (upper storage chamber 2a and lower storage chamber 2b) capable of individually adjusting the set temperature. The cooler 36a is assigned to lower the temperature of the upper storage chamber 2a to the set temperature, and the cooler 36b is assigned to lower the temperature of the lower storage chamber 2b to the set temperature. Further, the heating heater 25a is assigned for raising the temperature of the upper storage chamber 2a to the set temperature, and the heating heater 25b is assigned for raising the temperature of the lower storage chamber 2b to the set temperature. A fan 26a is installed to circulate the air in the upper storage chamber 2a, and a fan 26b is installed to circulate the air in the lower storage chamber 2b. Thereby, the temperature of two preservation | save chambers can be managed with high precision according to the objective.

  In addition, the wine cellar 1 of the present embodiment has a structure in which capacitors 33a and 33b that change the liquid refrigerant while dissipating the high-temperature and high-pressure gas refrigerant sent from the compressor 31 are arranged on the left and right side surfaces of the main body. Thereby, it becomes possible to make the depth dimension of the wine cellar 1 main body smaller than before. In addition, the condensation of the glass door 4 can be prevented by the heat generated by the capacitors 33a and 33b without installing a door heater for preventing condensation. Furthermore, since a door heater for preventing condensation is unnecessary, it is possible to keep power consumption low.
