Description

Technical field:

[0001] The utility model relates to the technical field of heat exchanger equipment, and more specifically to a refrigeration system for a steam box. Background technology:

[0002] The current steamer generally allows steam to enter the box body to steam the materials placed inside. However, the function of the existing steamer is only to steam the materials, and after steaming, the food is not taken out directly, but left inside. After a long time, the food will deteriorate, affecting its edibility;

[0003] Similarly, some steamers also have a reservation function, which requires the ingredients to be placed in the box in advance and steamed at the set time. In summer, if the ingredients are placed in the box in the morning and steamed in the evening, the box is closed and the weather is hot in summer. The ingredients in the box may have deteriorated at noon. When they are steamed in the evening, the taste of the ingredients will have changed, affecting their consumption. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a refrigeration system for a steamer, wherein an inner evaporating coil is arranged in the box body, which can refrigerate uncooked food in the box body to prevent it from spoiling, thereby ensuring the freshness of the food and facilitating subsequent steaming, and can also preserve the steamed food for subsequent heating and consumption.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A refrigeration system for a steam box, comprising a fixed bottom plate, a box body is fixed on the top surface of the fixed bottom plate, a rear support plate is fixed on the rear wall surface of the box body, a condenser is installed on the rear wall surface of the rear support plate, inner evaporation coils are installed on the inner side walls of the left and right side plates of the box body, a compressor seat is fixed to the rear of the top surface of the fixed bottom plate, and the compressor is fixed on the top surface of the compressor seat;

[0007] The feed inlet and the discharge outlet of the inner evaporating coil both extend out of the rear wall surface of the box body and the rear wall surface of the rear support plate, and the first three-way connector and the second three-way connector are both located behind the rear support plate.

[0008] A condenser connection seat is fixed on the rear wall surface of the rear support plate, the condenser is fixed on the rear wall surface of the condenser connection seat, and a heat dissipation fan is fixed on the rear wall surface of the condenser.

[0009] A plurality of limiting slide grooves are formed on the inner evaporating coil, and two adjacent inner evaporating coils correspond to each other on the left and right through a limiting slide groove of the same height.

[0010] A steam inlet through hole is formed in the middle of the rear wall plate of the box body.

[0011] The outstanding effects of the utility model are:

[0012] Compared with the prior art, an inner evaporating coil is provided in the box body, which can refrigerate the uncooked food in the box body to prevent it from spoiling, thereby ensuring the freshness of the food and facilitating subsequent steaming, and can also preserve the steamed food for subsequent heating and consumption.

[0016] Figure 4 It is a partial cross-sectional view of the utility model. Specific implementation method:

[0017] For example, see Figures 1 to 4 As shown, a refrigeration system for a steam box includes a fixed bottom plate 10, a box body 20 is fixed on the top surface of the fixed bottom plate 10, a rear support plate 21 is fixed on the rear wall surface of the box body 20, a condenser 30 is installed on the rear wall surface of the rear support plate 21, inner evaporation coils 40 are installed on the inner side walls of the left and right side plates of the box body 20, a compressor base 11 is fixed to the rear part of the top surface of the fixed bottom plate 10, and a compressor 50 is fixed on the top surface of the compressor base 11;

[0018] The feed inlet and the discharge outlet of the inner evaporating coil 40 extend out of the rear wall of the box body 20 and the rear wall of the rear support plate 21 , and the first three-way connector 1 and the second three-way connector 2 are both located behind the rear support plate 21 .

[0019] The air outlet of the compressor 50 is connected to the air inlet of the condenser 30 through a connecting pipe, the discharge port of the condenser 30 is connected to the feed port of the expansion valve 60 through a connecting pipe, the discharge hole of the expansion valve 60 is connected to a port of the first three-way connector 1 through a connecting pipe, the other two ports of the first three-way connector 1 are connected to the feed ports of the two inner evaporation coils 40 through a connecting pipe, the discharge ports of the two inner evaporation coils 40 are connected to the two ports of the second three-way connector 2 through a connecting pipe, and another port of the second three-way connector 2 is connected to the air inlet of the compressor 50 through a connecting pipe.

[0020] Furthermore, a condenser connecting seat 22 is fixed on the rear wall surface of the rear support plate 21, and the condenser 30 is fixed on the rear wall surface of the condenser connecting seat 22. Two cooling fans 31 are fixed on the rear wall surface of the condenser 30, and the two cooling fans 31 blow or suck air to the condenser 30 to dissipate heat.

[0021] Furthermore, a steam inlet hole 220 is formed in the middle of the rear wall plate of the box body 20. The steam inlet hole 220 can be connected to an external steam inlet pipe through a connecting pipe to achieve ventilation, which is a conventional structure and will not be described in detail here.

[0022] The inner evaporation coil 40 in this embodiment is S-shaped, and the front and rear parts of the left and right inner walls of the box body 20 are fixed with vertical connecting rods. The front and rear parts of the inner evaporation coil 40 are welded and fixed on the corresponding vertical connecting rods. The multiple U-shaped bent pipe parts extending backward on the inner evaporation coil 40 are away from the left side plate or the right side plate of the box body 10, that is, the corresponding U-shaped bent pipe parts of the two inner evaporation coils 40 are close to each other.

[0023] A limiting groove 41 is formed between the upper tube body and the lower tube body of the U-shaped bent tube part, and the limiting grooves 41 of the same height of two adjacent inner evaporating coils 40 correspond to each other on the left and right. This structure allows the left and right parts of the partition for placing food to be inserted into the corresponding limiting grooves 41 to achieve horizontal support.

[0024] The inner evaporating coil 40 can achieve the effect of refrigeration and also provide support for the plate on which the food is placed.

[0025] When the present embodiment is in use, when refrigeration is required, the refrigerant is formed into a high-temperature and high-pressure gas through the compressor 50, and then enters the condenser 30, and is blown by the heat dissipation fan 31 to improve its heat dissipation and cooling, so that the high-temperature and high-pressure gas refrigerant therein becomes a high-pressure gas-liquid mixed state, and then enters the expansion valve 60 to form a low-pressure gas-liquid mixed state, and then enters the inner evaporator coil 40, and the surface of the inner evaporator coil 40 exchanges heat with the air in the box body 20, and it absorbs heat in the air, so that the inside of the box body 20 is cooled. At the same time, the refrigerant becomes a low-temperature and low-pressure gas, and then flows back to the compressor 50, and circulates in this way in sequence, thereby realizing the cooling of the inside of the box body 20, so that the food inside can be kept fresh and cooled, thereby ensuring the freshness of uncooked food, facilitating subsequent steaming, and also preserving the steamed food for subsequent heating and consumption.
