Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ice cream production, in particular to an ice cream machine with good heat preservation effect. Background Art
[0002] Ice cream machines that use semiconductor cooling chips as cooling elements need to use radiators to dissipate heat from the hot end of the semiconductor cooling chips. Radiators are usually air-cooled or water-cooled, and water-cooled cooling has a significantly better heat dissipation effect than air-cooled cooling. In order to save water resources during water-cooled heat dissipation, circulating water is usually used to cool the hot end of the semiconductor cooling chip.
[0003] However, long-term use of circulating water for heat dissipation will cause the circulating water temperature to rise, which will inevitably reduce the heat dissipation efficiency of the semiconductor refrigeration sheet, thus easily affecting the refrigeration effect. In addition, during the refrigeration process, the ice cream raw material barrel itself will undergo heat exchange, which is closely related to the temperature change of the external environment. During the refrigeration process, due to the high external environment temperature, the heat exchange between the raw material barrel and the external environment will be intensified, which will not only reduce the refrigeration efficiency, but also prolong the refrigeration time and increase energy consumption.

DETAILED DESCRIPTION
[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figure 1-4 As shown, an ice cream machine with good heat preservation effect includes a bracket 1, a refrigeration component 2 and a cooling and heat preservation mechanism 3. The cooling and heat preservation mechanism 3 is installed on the top of the bracket 1, and the refrigeration component 2 is located below the cooling and heat preservation mechanism 3. The bracket 1 includes a bottom bracket 11, a top plate 12 and a support column 13. The top plate 12 is located above the bottom bracket 11. A plurality of support columns 13 are connected between the top plate 12 and the bottom bracket 11. The cooling and heat preservation mechanism 3 is installed on the top of the top plate 12, which is convenient for the cooling and heat preservation mechanism 3 and the refrigeration component 2 to be arranged in layers, which is beneficial to reducing the floor space and improving space utilization.
[0022] The cooling and heat preservation mechanism 3 includes an insulation barrel 31, an evaporator 32, an outer barrel 33 and an inner barrel 34. The outer barrel 33 is fitted on the outer side of the inner barrel 34, and the outer barrel 33 is located in the insulation barrel 31. The insulation barrel 31 is installed on the top of the bracket 1, and the insulation barrel 31 is used to support the outer barrel 33. The evaporator 32 is located between the insulation barrel 31 and the outer barrel 33, and the evaporator 32 is fitted with the outer wall of the outer barrel 33. In order to improve the insulation effect and reduce the loss of cold, in this embodiment, the cooling and heat preservation mechanism 3 also includes an insulation layer 35, which is a foaming material. The insulation layer 35 is filled and arranged between the insulation barrel 31 and the outer barrel 33, and the insulation layer 35 wraps the evaporator 32.
[0023] like Figure 3 As shown, the refrigeration assembly 2 includes a compressor 21, a condenser 22, a drying filter 23, a capillary tube 24 and a fan 25. The condenser 22 is installed between the top plate 12 and the base 11, the compressor 21 is installed on the top of the base 11, and the exhaust port of the compressor 21 is connected to the inlet of the condenser 22 through a high-pressure pipeline, the outlet of the condenser 22 is connected to the inlet of the drying filter 23, the outlet of the drying filter 23 is connected to the inlet of the capillary tube 24, the outlet of the capillary tube 24 is connected to the inlet of the evaporator 32, the outlet of the evaporator 32 is connected to the air intake port of the compressor 21 through a low-pressure pipeline, and the fan 25 is installed on the side of the condenser 22 close to the compressor 21.
[0024] It should be noted that the compressor 21 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas and transports it to the condenser 22. In the condenser 22, the high-temperature and high-pressure refrigerant gas is cooled and liquefied, releasing a large amount of heat. The fan 25 accelerates the heat exchange between the surface of the condenser 22 and the surrounding air by forced convection, thereby improving the heat dissipation efficiency. The liquid refrigerant enters the drying filter 23 to remove moisture and impurities therein. The capillary 24 generates a pressure drop by restricting the flow of the refrigerant, thereby reducing the pressure and temperature of the refrigerant. When the low-pressure liquid refrigerant enters the evaporator 32, the refrigerant begins to evaporate due to the sudden drop in pressure. This process absorbs a large amount of heat, causing the surface temperature of the evaporator 32 to drop, thereby achieving refrigeration. The evaporated refrigerant gas eventually returns to the compressor 21, is sucked in by the compressor 21 and compressed again, and a new cycle begins.
[0025] In order to facilitate the protection of the refrigeration component 2 and the cooling and heat preservation mechanism 3, in this embodiment, a fence 4 is fixedly installed on the top of the base 11, and a top cover 5 is installed on the top of the fence 4. The fence 4 and the top cover 5 are used to protect the refrigeration component 2 and the cooling and heat preservation mechanism 3, and both sides of the fence 4 near the bottom are provided with heat dissipation ports 41 corresponding to the fan 25 to facilitate air flow and heat dissipation of the refrigeration component 2. A barrel cover 51 corresponding to the barrel mouth of the inner barrel 34 is provided at the top center of the top cover 5, which facilitates the inner barrel 34 to be in a closed state, which can not only reduce the loss of cold, but also prevent the ice cream raw materials inside from being contaminated.
[0026] A connecting piece 6 is rotatably installed at the center of the barrel cover 51, and a stirring piece 7 rotatably arranged in the inner barrel 34 is installed at the bottom end of the connecting piece 6. A shell cover 8 covering the top cover 5 is detachably connected to the top of the enclosure 4, and a driving piece 9 is installed on the shell cover 8. The output end of the driving piece 9 is used to dock with the connecting piece 6.
[0027] It should be noted that stirring is required during the production of ice cream. When the output end of the driving member 9 is connected to the connecting member 6, the stirring member 7 can be driven to mix the ice cream ingredients in the inner barrel 34. In addition, the device of the present application can also be used to prepare yogurt. Since stirring is not required during the preparation of yogurt, the driving member 9 can be separated from the connecting member 6 by removing the shell cover 8.
[0028] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
