Description

[Detailed Description of the Invention] The present invention relates to a refrigerated wagon suitable for displaying and selling foods that need to be kept cold, such as cheese or cakes.

2. Description of the Related Art In order to sell food products that require cold storage by circulating them among customers in restaurants, hotels, etc., it is necessary to maintain the food products at a constant temperature.

Previously proposed refrigerated wagons, such as the 1980s
The wagon described in the microfilm photographing the contents of the specification and drawings attached to the application No. 181170 has a display storage compartment b (cover c) by placing an evaporator on the top of the main body a as shown in It forms a storage room (which can be opened and closed freely) and a stock room (the room inside the door b) to enable cooling at the same time.
A press handle e and a caster f are attached to the outside of the main body a to make it movable, and a power cord h is attached to drive a compressor installed in the machine room g of the main body a.

In the conventional technology described above, the wagon is equipped with casters so that it can be moved, but since it has a power cord, the range of movement of the wagon is naturally limited. This has caused problems such as the inability to move freely between seats in restaurants, hotels, etc. and sell food.

The present invention was developed to solve these conventional problems, and includes a refrigeration system that includes a compressor, evaporator, condenser, etc. that is driven by commercial power inside a frame equipped with casters. At the same time, a dish-shaped pedestal made of a heat insulating material is attached to the top of the frame, and the top surface of the pedestal is covered with a display stand with excellent heat storage performance, such as marble, to create a gap between the pedestal and the display stand. A thermostat for forming a duct in the duct, opening a cold air outlet of the refrigeration device into the duct, providing a drainage hole in the pedestal, further forming a display space on the top surface of the display stand, and controlling the internal temperature of the display space. The wagon is equipped with a cover equipped with a refrigerator, operates a refrigeration system to supply cold air to the stand, turns off the power after the display stand is kept cold, and can move freely to sell food. This is what we are trying to provide.

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. An electric refrigeration device 3 is housed inside an underframe 2 provided with casters 1, 1. The refrigeration system 3 includes a refrigerant compressor 4, an evaporator 5, and a condenser 6 connected to the compressor 4, and can receive commercial power through a power cord (not shown).

Further, as described above, the underframe 2 that houses the refrigeration device 3
A dish-shaped pedestal 7 made of a heat insulating material is attached to the upper end of the holder. Further, the upper surface of the pedestal 7 is covered with a display pedestal 8 made of a material with excellent heat storage properties such as marble, and a duct 9 is formed between the display pedestal 8 and the pedestal 7.
A cold air outlet 10 of the evaporator 5 is opened in the duct 9. 11 is a blower for the evaporator 5; 12 is a drainage hole provided on the pedestal 7; 13 is a cover that covers the top surface of the display stand 8 so as to be openable and closable; 14 is a ventilation hole provided on the display stand 8; A thermostat 16 for controlling the refrigeration device 3 is provided inside the covered display space 15.

In the above configuration, when a power cord (not shown) is plugged into a commercial power outlet, the compressor 4 and the blower 11 are operated and cold air is blown into the duct 9 from the cold air outlet 10 of the evaporator 5. When cold air is supplied to the duct 9 in this way, the temperature inside the duct 9 decreases, and the display stand 8 made of marble is cooled.
Cool air is also supplied to the display space 15 from the ventilation holes 14 formed in the display space 15.

When the temperature of the display stand 8 drops to a predetermined temperature as described above and the freezing device 3 stops under the control of the thermostat 16, arrange the cheese, cake, etc. on the display stand 8, pull out the power cord from the outlet, and connect the stand to the frame. Sales are carried out while moving 2 to an arbitrary position. It is needless to mention in detail that the refrigeration device 3 may be operated with the cheeses etc. arranged on the display stand 8.

Then, the display stand 8 is controlled by the thermostat 16.
When it is detected that the temperature of the display space (the temperature of the display space) has risen above a predetermined value, the sales operation is interrupted, the power cord is connected to the commercial power outlet again, the refrigeration device 3 is operated, and the display stand 8 is Reduce temperature again.

In the embodiment, a ventilation hole 14 is provided in the display stand 8, but when displaying food that is sensitive to wind, such as when displaying a cake, it is necessary to omit the ventilation hole to prevent the cake from drying out.

Further, in the embodiment, the display stand is made of marble, which has excellent heat storage performance and decorative effect, but the display stand may be made of other stones such as granite, or metal that is resistant to rust. .

As explained above, according to the present invention, the display stand that forms the bottom wall of the display space is made of a material with excellent heat storage performance, such as marble, and the display stand is cooled with cold air blown from the refrigeration device. Since the display space is kept cool, the food on the display stand can be kept cool at a constant low temperature even if the wagon is moved freely by operating the refrigeration equipment at predetermined intervals. It is.

In addition, since the refrigeration equipment is electric, it is easy to operate when selling food to restaurants, hotels, etc., and it is clean when displaying and selling food, with excellent cold storage performance and handling performance. It is possible to easily perform various wagon services by providing an excellent refrigerated wagon.
