[Field of Industrial Application] The present invention relates to a hot and cold showcase in which a hot room is formed in a part of a cold room in a warehouse as needed, and hot products can be displayed in a warm state. .

0002

BACKGROUND OF THE INVENTION Most of the showcases currently available on the market are for refrigerating and freezing purposes only. On the other hand, as a special showcase, a hot-and-cold showcase, which has a cold chamber and a hot chamber inside the refrigerator as mentioned above, has been proposed, for example, in Japanese Utility Model Application Publication No. 55-111086. Here, in the hot and cold showcase proposed above, a hot room is defined in a part of the interior of the showcase, which is separate and independent from the cold room and is equipped with a hot air generator and a dedicated front door. , and a damper for cutting off cold air introduction is provided between the hot chamber and the cold chamber, and the mode of use of the hot chamber is switched between hot and cold as necessary.

0003

However, the hot and cold showcase described above has the following drawbacks. (1) Although the hot chamber can be used by switching between hot and cold modes, the hot chamber is designed to be separated from the cold chamber in advance, so it is not a general showcase made exclusively for refrigeration. cannot be easily modified according to customer requirements. (2) Additionally, since the hot room has a dedicated front door that is separate from the front door of the cold room, the structure of the showcase is complicated and costly, and customers cannot freely select products from the showcase. When taking out the cold chamber door, the cold chamber door and the hot chamber door must be opened and closed separately, which is cumbersome.

[0004] The present invention has been made in consideration of the above points, and it is possible to meet the customer's requirements at the place where the showcase is installed, without requiring major modification of the case, compared to a general showcase made exclusively for refrigeration. To provide a showcase for hot and cold in which a hot chamber can be easily provided in a refrigerator according to the requirements.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a showcase with a transparent door on the front side, which occupies a part of the interior of the cold room and has an open-front type insulation. A hot chamber with a built-in heater and fan is removably installed in the housing, and the open end of the hot chamber is closed with a see-through door of the showcase.

[0006] Here, as a means to reliably prevent the warm air in the hot room from leaking into the cold room, it is preferable to provide a sealing gasket on the front peripheral edge of the heat insulating casing that comes into contact with the door surface of the see-through door. In addition, in order to easily assemble the hot chamber inside the showcase if necessary, the hot chamber's insulated casing has an assembly type structure in which the bottom wall and ceiling wall can be disassembled. The rear wall, left and right side walls, excluding the front wall, can be fixedly placed inside the cold room. Furthermore, for the hot chamber with this prefabricated structure, a heater and a fan can be installed in advance on the ceiling wall of the heat insulating casing.

[0007]

[Function] According to the above structure, a hot chamber is defined in a part of the cold chamber in the showcase by using the heat insulating casing as a partition wall, and the open end surface of the hot chamber is seen through the showcase where the open end surface is common to the cold chamber. blocked by a door. Therefore, there is no possibility that the cold air from the cold room and the warm air from the hot room will mix inside the refrigerator. In addition, when the hot room is not used, it is possible to remove the heat insulating case from the showcase, or by disassembling and removing only the ceiling and bottom walls of the heat insulating case, allowing the hot room to be used as a hot room. The space can be used as it is as a cold room, and even if a hot room is required, the hot room can be easily assembled inside the cold room while leaving the showcase itself intact.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. First, in FIGS. 1 and 2, 1 is the outer box of the showcase, 2 is the double-sided see-through door provided on the front of the case, 3 is the vertical multi-tiered product display shelf installed in the cold chamber 4 inside the warehouse, and 5
is a refrigerator cooler installed in the cold air circulation duct inside the refrigerator,
6 is a cold air circulation fan, and 7 is a hot chamber installed above the cold chamber 3. Here, as the detailed structure of the hot chamber 7 is shown in FIGS. 3 and 4, an air heating heater 9 and a fan 10 are built in an insulating casing 8 with an open front, and the front of the insulating casing 8 is A sealing gasket 11 that comes into contact with the door surface of the see-through door 2 is provided on the peripheral edge. Note that 12 is a ventilation duct incorporating a heater 9 and a fan 10, and 13 is a lighting lamp for the hot room.

The hot room 7 having such a structure is installed on the product display shelf 3 so as to occupy a part of the cold room 4, and is connected to various electrical components such as the heater 9, the fan 10, the lighting lamp 13, etc. It is used by providing the necessary wiring between it and the power supply circuit on the case side. In this state of use, warm air heated by the heater 9 is circulated through the hot chamber 7 by the fan 10 to keep the hot products stored in the chamber warm. Note that when the front transparent door 2 of the showcase is closed, the gasket 1 attached to the front edge of the heat insulating case 8
Since the door surface of the see-through door 2 contacts the door 3 and closes the open end surface of the hot chamber 7, the warm air circulating in the hot chamber and the cold air circulating in the cold chamber do not mix. If the hot chamber 7 is not needed, it can be removed from the showcase as shown by the chain line in Figure 1, and the space previously occupied by the hot chamber 7 can be used as a cold chamber and the showcase can be used exclusively for refrigeration. .

Next, an applied example regarding a hot chamber is shown in FIG. In this embodiment, the heat-insulating casing 8 of the hot room is made as a prefabricated casing that combines a ceiling wall 8a, a bottom wall 8b, left and right side walls 8c, 8d, and a rear wall 8e, and the ceiling wall 8a and the bottom wall 8b is assembled so that it can be pulled out and disassembled from the left and right side walls 8c and 8d in the direction of the arrow. Of the above-mentioned walls, the left and right side walls 8c, 8d and the rear wall 8e are fixedly installed in the cold chamber 4 (see FIG. 1) in advance.
