Description

Warm and cold dining cart {Worm and cold dining cart}

The present invention relates to a serving car for transporting food placed on a plate, in particular, the food for refrigerated storage in a refrigerated state, and the food for storage in a warm room for a cold-cooled serving car for transporting.

In the case of a general hospital where a lot of patients with inconvenient behavior are gathered, appropriate foods are cooked in a restaurant according to the condition of each patient, and then transported to a ward room where the patient is able to eat and drink.

It is almost impossible to deliver a patient's meal three times a day individually to a ward with hundreds of patients. Therefore, where a lot of people with discomfort such as a hospital are gathered, the food is transported using a serving car that can carry several tens of meals at a time.

These plates are stacked with a plurality of plates spaced at regular intervals, and these plates are loaded with food suitable for each patient. Therefore, the nurse or assistant assists the patient in eating the food prepared for each patient in the serving car, transferring the plate in the serving car to the patient after transporting to the ward room where the patient is located.

In the conventional dismantling car, a support that is capable of supporting both ends of the tray is located therein, and the tray is moved to the tray while the tray is seated on the support.

When using such a conventional breeding car, the following various problems occur.

First, the foods eaten during the meal are divided into warm and cold foods, which are indiscriminately placed on the plate, so that the warmth of the hot food is transferred to the cold food and the cold food to the hot food. Since the food and drink is not able to eat the food at a temperature suitable for eating, there is a disadvantage that the appetite falls.

Second, nutritious foods generally rot easily, and to prevent this, nutritious foods are refrigerated to maintain their freshness. However, as described above, since various foods are loaded indiscriminately in a conventional serving car, the foods to be refrigerated due to heat exchange of each food are easily decayed.

The present invention is proposed in order to solve the problems of the prior art as described above, by separately controlling the temperature of food put on the plate into a refrigerated storage food and warm storage food, to maintain the freshness of food and appetite of the food and drink Its purpose is to provide hot and cold serving tea.

The plate (1) arranged separately from the refrigerated food (2C) and warm food (2H) is stored in the left and right plate storage space (30L) and the right plate storage space (30R) from the front and rear, wherein the middle portion of the plate (1) The left and right side walls of the support 60 and the left and right side plate storage spaces 30L and 30R which are inserted into the grooves 41 of the plate blocking film 40 and fixed to both ends of the plate 1 are respectively fixed to the cooling fan cold storage space 20. It rests on the support 60 fixed to it. Then, when the plate 1 is inserted into the groove 41 of the plate blocking film 40, the lower silicon packing 46L of the channel 43 moves upward and presses the middle portion of the plate 1 to shake the plate 1. Support it. When the plate 1 is pushed inward in the vehicle body 10 in this state, the plate 1 is in contact with the central reinforcement 70 and no longer enters.

In this way, when both of the trays 1 are accommodated in the left and right side tray storage spaces 30L and 30R, the front and rear doors 12 are closed, and a plug is connected to the outlet 87 to supply power. Then, the heat exchanger located in the machine room 80 takes the internal heat of the cooling fan cold storage space 20 to lower the temperature. At this time, while the fan 22 is driven, the cool air inside the cooling fan cold storage space 20 is discharged to the refrigerating space 31L of the left and right side plate storage spaces 30L and 30R. Here, the refrigerating space 31L is a space between the plate blocking membrane 40 of the left and right side plate storage spaces 30L and 30R and the cooling fan cold storage space 20.

The cold air does not flow to the warming space 31H in which the hot plate 50 is positioned by the plate blocking film 40, and cools the refrigerated space 31L to maintain the freshness of the refrigerated food 2C.

On the other hand, the hot plate 50 generates heat, and the heat keeps warm food 2H. At this time, since the hot plate 50 is located throughout the inner surface of the vehicle body 10, the amount of heat supplied to each food plate 1 is almost the same.

In this way, the refrigerated food (2C) and heated food (2H) is transferred to the serving car 100 and provided to the drinker. At this time, when the plate 1 is pulled out from the groove 41 of the plate blocking film 40, the lower silicon packing 46L of the channel 43 is different from the upper silicon packing 46H of the other channel 43 positioned below it. By blocking the air flow between the refrigerating space 31L and the warming space 31H, when the door 12 is opened for a short time, the cold and warmth of the left and right plate storage spaces 30L and 30R are continuously maintained for a while. Can be maintained.

As described in detail above, the hot and cold serving tea of the present invention can control the temperature of the refrigerated storage food and the food storage food stored on the plate separately, so that the appetite of the drinker is active and the freshness of the food can be improved. There is this.

In addition, the hot-cold serving car of the present invention has an advantage of high thermal efficiency because it blocks the exchange of hot and cold air even when the plate is inserted into or taken out of the plate blocking membrane.

In the above description, the technical idea of the hot and cold meal car of the present invention has been described together with the accompanying drawings, but this is only illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
