[Technical Field]

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular relates to a high-efficiency refrigeration equipment. [Background Technology]

[0002] All existing refrigeration equipment in the industry, such as smoothie machines, suffer from long production times, taking more than 35 minutes from start to finish. They generally use either air cooling or water cooling. Existing air-cooled refrigeration equipment uses a compressor to input refrigerant into the evaporator, and then a fan carries the cold air from the compressor to achieve cooling. Existing water-cooled refrigeration equipment places the evaporator in a water tank and cools the water in the tank through heat exchange with the evaporator. This method of cooling solely through the evaporator is inefficient and seriously affects the user experience. [Utility Model Content]

[0003] The purpose of this invention is to provide a high-efficiency refrigeration device with high refrigeration efficiency and a better user experience.

[0014] As described above, in a high-efficiency refrigeration device, the water tank outlet is located below the evaporator, and the water tank inlet is located above the evaporator.

[0015] As described above, in a high-efficiency refrigeration device, the water outlet of the water-cooled pipe is equipped with a second thermostat for detecting the water temperature in the outlet.

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this utility model, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Specific embodiments, such as Figure 1-3 The refrigeration equipment shown includes: a cooling water tank 1, which has a water tank cavity 11, and a water tank outlet 12 and a water tank inlet 13 connected to the water tank cavity 11; an evaporator 2, which includes an evaporator cavity 21, and a refrigerant inlet channel 22 and a refrigerant outlet channel 23 connected to the evaporator cavity 21; a water-cooled pipe 3, which includes a water-cooled section 31 disposed in the evaporator cavity 21, a water outlet section 32 connected to the water-cooled section 31, and a water inlet section 33 connected to the water-cooled section 31, wherein the water outlet section 32 is connected to the water tank inlet 13; and a water pump 4, whose inlet end is connected to the water tank outlet 12 and whose outlet end is connected to the water inlet section 33. During cooling, the refrigerant enters the evaporator cavity through the refrigerant inlet channel, and the evaporator achieves the cooling effect. After heat exchange, the refrigerant returns to the compressor through the refrigerant outlet channel. In addition, this application uses a water pump to pump water from the water tank cavity from the water tank outlet through the water inlet to the water cooling section. When the water flows through the water cooling section, it exchanges heat with the refrigerant in the evaporator cavity and then flows through the water outlet back to the water tank cavity from the water tank inlet, realizing cyclic cooling, which has high cooling efficiency and a better user experience.

[0027] Specifically, in order to increase the heat exchange area between the water flow and the refrigerant and improve the refrigeration efficiency, the water-cooling section 31 is in the shape of a spiral tube.

[0028] More specifically, in order to increase the heat exchange area between the water flow and the refrigerant and improve the refrigeration efficiency, the end of the water-cooled section 31 extends to the end of the evaporator cavity 21.

[0029] In addition, the evaporator 2 is located in the inner cavity 11 of the water tank. The water in the inner cavity 11 of the water tank is cooled directly by the evaporator 2. Compared with the air-cooled cooling method of the fan and the evaporator 2, the noise is lower and the cooling efficiency is higher.

[0030] Furthermore, the high-efficiency refrigeration equipment also includes a compressor 6 and a condenser 7. The compressor 6 is connected to the refrigerant outlet channel 23, and one end of the condenser 7 is connected to the compressor 6, while the other end is connected to the refrigerant inlet channel 22 via a capillary tube 8. The evaporator is used to absorb heat from the water by exchanging heat between the low-temperature, low-pressure liquid refrigerant and the water in the inner cavity 11 of the water tank and the circulating water flowing through the water-cooling pipe 3, thereby evaporating the low-temperature, low-pressure liquid refrigerant into a low-temperature, low-pressure gaseous refrigerant. During the evaporation process, the temperature of the refrigerant remains constant. The compressor generates mechanical energy, which is used to keep the refrigerant in a gaseous or liquid state, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The condenser is used to compress the high-temperature, high-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The refrigerant exchanges heat with the indoor medium, transforming the high-temperature, high-pressure gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant. During this process, the refrigerant temperature remains constant. The capillary tube throttles the high-temperature, high-pressure liquid refrigerant, cooling it down. After throttling, the high-temperature, high-pressure liquid refrigerant becomes a lower-temperature, lower-pressure liquid refrigerant, which then enters the evaporator and exchanges heat with the water in the water tank cavity 11 and the circulating water flowing through the water-cooling pipe 3 to achieve efficient cooling.

[0031] More specifically, the water tank outlet 12 is located below the evaporator 2, and the water tank inlet 13 is located above the evaporator 2. Water in the inner cavity 11 of the water tank flows out from the water tank outlet 12 located below the evaporator 2 through a water pump and is pumped into the water-cooling pipe 3. After heat exchange and cooling through the water-cooling pipe, it flows back into the inner cavity 11 of the water tank through the water tank inlet 13 located above the evaporator 2, thus realizing water circulation cooling.

[0032] Furthermore, it also includes a first thermostat 5, which is installed on the chilled water tank 1 to detect the water temperature in the inner cavity 11 of the tank. The first thermostat 5 is electrically connected to the compressor 6 to drive the compressor 6 to start and stop. By controlling the start and stop of the compressor based on the detected water temperature in the inner cavity of the tank, the automatic start and stop of the compressor ensures that the water temperature in the inner cavity of the tank, after absorbing heat from the refrigerant, remains constant or reaches the preset temperature, making it more convenient to use and providing a better user experience.

[0033] Furthermore, the water outlet 32 ​​of the water-cooling pipe 3 is equipped with a second thermostat 9 for detecting the water temperature in the water outlet 32.

[0034] Specifically, the second thermostat 9 is electrically connected to the water pump 4 to drive the water pump 4 to start and stop. The start and stop of the water pump 4 are controlled based on the detected water temperature after heat exchange through the water-cooling pipe 3, thereby controlling the circulation and cooling of the circulating water flow. This ensures that the water temperature inside the water tank remains constant or reaches a preset temperature, making it more convenient to use and providing a better user experience.

[0035] The above description is one embodiment provided in conjunction with specific content, and does not imply that the specific implementation of this utility model is limited to these descriptions. Furthermore, due to different industry naming conventions, it is not limited to the above names or the English names. Any methods or structures similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
