(C) Problem to be Solved by the Invention According to the above-mentioned conventional technique, in order to increase the operation rate of the refrigerated showcase in winter, a heater for heating and a blower fan A are provided in the upper part of the refrigerator. However, since the heating heater and the blower fan A, which are not used except during the winter season, are placed on the upper part of the inside of the refrigerator, there is a problem that the effective internal volume of the refrigerator is impaired, and a shielding plate is attached. There was a problem that the entire inside of the refrigerator could not be refrigerated in this state.

The present invention is intended to solve the above problems,
The above object is achieved by providing a heating element in a partition member that divides the storage chamber into upper and lower parts, and by providing a hollow portion, a frame having an opening, and an opening / closing member.

The storage chamber and the installed cooling chamber, the bottom plate which is arranged at the boundary between the storage chamber and the cooling chamber, and which connects the both chambers to each other to form a blowout port and a suction port along both edges facing each other, and the storage chamber. A partition plate divided into upper and lower parts, the partition member comprising an upper plate having a heating element such as an electric heater, a lower plate, and a heat insulating material filled between the upper and lower plates; A hollow portion is formed in a portion facing both the blowout and suction ports, at least two frames are formed on the upper and lower surfaces of the hollow portion, and are attached to the heat insulating plate, and both upper and lower openings of the both frames are openably and closably closed. A structure including an opening / closing member that opens and closes is adopted.

(E) Operation According to the above means, in the case of the combined cooling and heating operation, the upper and lower openings of the left and right frames are closed by the opening / closing members, and each hollow part of the both frames acts as a heat insulating space. , Heating elements (30)
Is energized, and the cool air that has undergone heat exchange in the cooler is forcedly circulated by the blower to cool the storage chamber or refrigeration area below the partition member, while the warm air from the heating element rises to the storage chamber or temperature above the partition member. Heat the storage area.

Also, in the case of only the cooling operation, both the upper and lower openings of the hollow portion can be opened by the opening / closing member, and the heating element becomes non-conductive
Cold air is forcedly circulated through the hollow portions of both frames to cool the entire storage chamber.

Next, the cooling and heating combined operation and the cooling operation in the storage (1) will be described.

In the case of combined cooling and heating operation, the upper and lower openings (41A) and (41B) of the left and right frames (35C) and (35D) are closed by the opening and closing members (42A) and (42B), and the both frames (35C) ( Each hollow part (37C) (37D) of (35D) acts as an adiabatic space, while the heating element (30) is energized to cool the cooler.
The cool air that has undergone heat exchange in (23) is forcedly circulated by the blower (24) as shown by the solid line arrow in FIG.
(3) That is, the refrigerating zone is cooled, while warm air from the heating element (30) rises as shown by the chain line arrow in FIG. 2 to heat the storage chamber (3) or the refrigerating zone above the partition member (21). In this case, the storage room (3)
The ratio of the cooling and heating spaces is changed by changing the arrangement positions of the partition member (21) and the gasket contact member (50).

Further, in the case of only the cooling operation, the upper and lower openings (41A) (41B) of the hollow portions (37C) (37D) are opened by the opening / closing members (42A) (42B), and the heating element (30) is not opened. When electricity is turned on, the cold air is forcedly circulated through the hollow portions (37C) and (37D) of the left and right frames (35C) and (35D) as indicated by solid line arrows in FIG. 6, and cools the entire storage chamber (3). That is, in such a case, the hollow portion (37C) and the upper and lower openings (41A) (41B) of the one frame (35C) pass the return cool air from the refrigerating area above the partition member (21) to the lower refrigerating area. It acts as a passage that causes the hollow part (37D) of the other frame (35D) and both upper and lower openings (41A).
(41B) acts as a passage for passing the supply cold air from the refrigerating area below the partition member (21) to the refrigerating area above.

(G) Effects of the Invention According to the present invention described above, the effects listed below occur.

In the case of combined cooling (refrigeration) and heating (hot storage) operation in which the heating element is energized, the upper and lower openings of both frames are closed by opening and closing members, and each hollow part becomes a sealed state and acts as a heat insulating space. Both frames, together with the heat insulating plate, prevent heat transfer between the refrigerating and warming zones, and as a result, the refrigerating and warmer zones can be maintained at a predetermined temperature.

In the case of only cooling (refrigeration) operation in which the heating element is not energized, both upper and lower openings of both frames are open, and the hollow part and the upper and lower refrigerating areas communicate with each other through the openings, so that the hollow of one frame The upper part and the upper and lower openings function as a passage for passing return cool air from the refrigerating area above the partition member to the lower refrigerating area, and the hollow part and the upper and lower openings of the other frame are located above the refrigerating area below the partition member. Since it functions as a passage for passing the cold air supplied to the refrigerating zone, the entire storage chamber can be maintained at a predetermined temperature without removing the partition member by a simple operation of the opening / closing member.
