DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a storage compartment in which the interior of a compartment is partitioned into an upper storage compartment and a lower storage compartment by a partition member.

2. Description of the Related Art In Japanese Patent Publication No. 52-44824, a heating heater 6 and a blower fan A7 are provided at either the upper part or the lower part of a chamber 2 surrounded by glass or the like. Refrigerated evaporator 8 and blower fan B9
, A detachable shielding plate 4 is hung at substantially the center of the interior 2, a refrigeration circuit 13 and a warming circuit 10 are provided in parallel as electric circuits, and a contact 18 c of a changeover switch 18 connected to a power supply 19. Contact 18a connected to the refrigeration circuit 13 and the refrigeration circuit 1
0 shows a refrigeration / warming showcase in which a series circuit of a microswitch 5 and a manual switch 17 is connected between the contacts 18a and 18b of the two circuits by the attachment and detachment of the shield plate 4 between the contacts 18a and 18b of the two circuits. I have.

According to the technique disclosed in the above-mentioned publication, when the shield plate 4 is mounted, one of the compartments partitioned by the shield plate 4 and in which the heater 6 is disposed is heated. It becomes a refrigeration state, and the other inside becomes a refrigeration state. On the other hand, when the shielding plate 4 is removed, if the changeover switch 18 is moved to the contact 18b side, the whole inside of the refrigerator becomes a warm state, and if the switch 18 is moved to the contact 18a side, the whole inside becomes a refrigerated state. However, in order to change the inside of the refrigerator to the refrigerated state or the warmed state from one in which the refrigerator is in a refrigerated state and the other is in a refrigerated state, the shielding plate 4 must be removed. In addition, in order to perform the work of removing the shielding plate 4, it is necessary to remove the goods in the refrigerator, which is very troublesome, and there is a problem that the operation state cannot be changed quickly.

Therefore, in the present invention, in order to solve these problems,
An object of the present invention is to provide a storage in which a heat insulating partition member that partitions the inside of the storage up and down is improved.

Means for Solving the Problems The storage of the present invention has an opening on the front surface, an insulation box serving as a storage main body, and an upper storage room and a lower storage room which partition the inside of the storage into front and rear portions, respectively. A heat insulating partition member having a front communication port and a rear communication port, a front opening / closing device for opening / closing the front communication port, a rear opening / closing device for opening / closing the rear communication port, and a blower disposed along the back of the upper storage room. An upper partition plate forming an upper passage to be installed, a suction opening formed between a lower end of the upper partition plate and a heat insulating partition member, and a lower portion disposed along the back of the lower storage room and installing a blower; A lower partition plate forming a passage, and an outlet formed between an upper end of the lower partition plate and the heat insulating partition member, the rear opening and closing device includes a first opening and closing unit that opens and closes the rear communication opening; A second opening / closing unit for opening / closing the suction port, and a third opening / closing unit for opening / closing the air outlet, During occlusion of 絡口, blocking an upper passage and a lower passage, upon opening of the rear communication port, in which so as to communicate the upper passage and a lower passage.

Further, if the first heater is provided on the leeward side of the blower of the upper passage and the evaporator is provided on the leeward side of the blower of the lower passage, the storage can be used as a refrigerator and a refrigerator. It is valid.

Further, if a second heater that is energized when the cooling operation is stopped is disposed on the downwind side of the evaporator, it is effective to uniformly control the temperature in the storage during the warming operation of the entire storage. .

Operation (1) When the front opening is opened by the front opening / closing device, the front opening acts to connect the upper and lower storage chambers, and when the rear opening is opened by the rear opening / closing device, the rear opening is moved up and down. A series of air circulation paths are formed in the entire storage in a state where the inside of the storage is vertically divided by acting so as to communicate the two passages.

(2) When the front opening is closed by the front opening and closing device, the front opening and closing device acts to make the upper and lower storage rooms independent, and when the rear opening and closing device is closed by the rear opening and closing device, the rear opening and closing device blows. The outlet and the air inlet are respectively opened to act to form independent air flow passages in both the upper and lower storage chambers.

On the other hand, in the above state (1), if the circulation of the refrigerant of the evaporator is stopped and the first heater is operated in order to keep the entire storage at the warm storage specification, the first heater heats the entire storage. And the reverse operation, the evaporator acts to cool the entire storage.

On the other hand, when the first heater is operated in the state (2), the first heater acts to heat the upper storage chamber. Further, when the second heater is operated, the second heater acts to heat the lower storage chamber, and when the second heater is stopped, the evaporator acts to cool the lower storage chamber.

An embodiment of the present invention will be described below with reference to the drawings.

[Effects of the Invention] As described in detail above, the present invention has the following effects.

When the front opening is opened by the front opening / closing device, the front opening is
The upper and lower storage compartments are connected to each other, and when the rear opening is opened by the rear opening / closing device, the rear communication opening acts to connect the upper and lower passages, so that the interior of the storage compartment is vertically divided. Thus, a series of air circulation paths can be formed between the upper and lower parts.

When the front opening / closing device closes the front communication port, the front opening / closing device acts to block the air flow between the upper and lower storage chambers. In addition, independent air flow passages can be formed in both the upper and lower storage chambers because they act to open the suction port.

On the other hand, in the state shown above, if the refrigerant circulation of the evaporator is stopped and the first heater is operated, the heat insulating partition member is moved because the first heater acts to heat the entire inside of the storage. Without removing, the whole inside of the storage can be used as a warm storage, and if the first heater is stopped to circulate the refrigerant of the evaporator, the evaporator acts to cool the whole storage, The entire storage can be used as a refrigerator without removing the heat insulating partition member.

On the other hand, in the state shown above, if the refrigerant circulation of the evaporator is stopped and the first heater is operated and the second heater is operated, the first heater acts to heat the upper storage chamber. Since the second heater acts to heat the lower storage compartment, the upper and lower storage compartments can be used as the storage compartments in a state where the interior of the storage compartment is completely partitioned up and down. In this case, a circulating air flow can be created by the air blower, and temperature unevenness in each storage room can be suppressed.
Also, by operating the first heater and circulating the refrigerant of the evaporator,
The upper storage room can be a storage room and the lower storage room can be a refrigerator room.
