Description

Technical Field

[0001] This application relates to the field of refrigerants, and more particularly to a refrigeration machine having an evaporator. Background Technology

[0002] As a core component of commercial and residential refrigeration equipment, the performance of the evaporator directly affects the overall energy efficiency ratio and ice-making efficiency of the refrigeration unit. Currently, mainstream evaporators employ a structure where heat exchange occurs between the refrigerant and metal pipes. The contact method between the refrigerant pipes and the inner wall of the evaporator, as well as the pipe layout design, are key factors determining heat exchange efficiency.

[0003] In existing technologies, refrigeration evaporators mainly consist of a refrigeration shell and refrigeration pipes installed within it. The refrigeration pipes are mostly spirally wound circular tubes, spirally wound along the inner wall of the refrigeration shell. However, in these refrigeration evaporators, the contact area between the refrigeration pipes and the refrigeration shell is small, forming only a narrow linear contact area, resulting in unsatisfactory cooling performance. In response to the aforementioned technologies, the inventor provides a refrigeration machine with an evaporator. Utility Model Content

[0004] In order to improve the refrigeration efficiency of the refrigeration machine, this application provides a refrigeration machine with an evaporator.

[0005] The refrigeration unit with an evaporator provided in this application adopts the following technical solution: A refrigerator with an evaporator includes a mounting housing, a refrigeration evaporator mounted on the mounting housing, a cooling water tank for holding cooling water, and a water outlet assembly for discharging water. A refrigeration chamber for supplying drinking water is provided between the refrigeration evaporator and the mounting housing. The refrigeration evaporator includes a refrigeration housing and a refrigeration assembly mounted on the inner wall of the refrigeration housing. The refrigeration assembly includes a refrigeration pipe fitted against the inner wall of the refrigeration housing, an inlet pipe connected to the cooling water tank for conveying cooling water into the refrigeration pipe, and an outlet pipe for discharging cooling water from the refrigeration pipe. The refrigeration pipe has a semi-elliptical cross-section and a refrigeration surface fitted against the refrigeration housing.

[0006] By adopting the above technical solution, drinking water can be placed in the refrigeration chamber between the refrigeration evaporator and the mounting shell. The refrigeration component delivers cooling water from the cooling water tank to the refrigeration pipe through the water inlet pipe, and then outputs it through the water outlet pipe. The refrigeration pipe with a semi-elliptical cross-section and a refrigeration surface fits into the inner wall of the refrigeration shell, which can increase the contact area with the refrigeration shell and improve the refrigeration efficiency.

[0007] Optionally, the refrigeration pipe includes multiple annular refrigeration branch pipes axially arranged within the refrigeration housing and connecting pipes connecting adjacent annular refrigeration branch pipes.

[0008] By adopting the above technical solution, the refrigeration pipeline uses multiple axially arranged annular refrigeration branch pipes and connecting pipes connecting adjacent annular refrigeration branch pipes, which can increase the refrigeration area and thus improve the refrigeration efficiency.

[0009] Optionally, the annular refrigeration branch pipe has an inlet and an outlet arranged axially symmetrically with respect to the inlet, and the connecting pipe connects the outlet of one annular refrigeration branch pipe to the inlet of an adjacent annular refrigeration branch pipe.

[0010] By adopting the above technical solution, the inlet and outlet of the annular refrigeration branch pipe are axially symmetrically arranged and the connecting pipe connects the outlet and inlet of the adjacent annular refrigeration branch pipe. This makes the cooling water flow more orderly in the refrigeration pipe, and can cool drinking water in the refrigeration chamber more efficiently, thereby improving the refrigeration effect.

[0011] Optionally, the connecting pipe is arranged perpendicular to the annular refrigeration branch pipe.

[0012] By adopting the above technical solution, the outlet and inlet of the pipe are connected to the adjacent annular refrigeration branch pipe and arranged perpendicularly to the annular refrigeration branch pipe, making the flow of cooling water in the refrigeration pipeline smoother and more orderly, which can improve refrigeration efficiency and enhance refrigeration effect.

[0013] Optionally, the refrigeration pipe is integrally injection molded with the refrigeration housing.

[0014] By adopting the above technical solution, the refrigeration pipe and the refrigeration shell are integrally injection molded, making the two tightly bonded, reducing the gap between the refrigeration pipe and the refrigeration shell, reducing thermal resistance, and improving refrigeration efficiency.

[0015] Optionally, the diameter of the inlet pipe is larger than the diameter of the outlet pipe.

[0016] By adopting the above technical solution, the inlet pipe diameter is set to be larger than the outlet pipe diameter, which allows more cooling water to enter the refrigeration pipe, increases the pressure and flow rate of the cooling water in the refrigeration pipe, improves refrigeration efficiency, and ensures the refrigeration effect of the refrigeration unit.

[0017] Optionally, the refrigeration evaporator further includes a stirring mechanism rotatably mounted on the refrigeration housing. The stirring mechanism includes a rotating shaft rotatably mounted on the refrigeration housing, stirring blades mounted on the rotating shaft, and a rotation drive assembly for driving the rotating shaft to rotate. The extending direction of the rotating shaft is arranged parallel to the axial direction of the refrigeration housing, and a sealing element is provided between the rotating shaft and the top of the refrigeration housing.

[0018] By adopting the above technical solution, the specific structure of the stirring mechanism is disclosed. The stirring mechanism is composed of a rotating shaft and stirring blades to stir drinking water. The rotating shaft is set in a direction parallel to the axis of the refrigeration shell so that the refrigeration evaporator can ensure uniform stirring. The rotating shaft is set with a sealing element at the top of the refrigeration shell to help enhance the sealing of the refrigeration chamber and reduce the risk of drinking water entering the evaporator.

[0019] Optionally, the stirring blade includes a first stirring part mounted on the rotating shaft and circumferentially arranged on the outer wall of the refrigeration housing, and a second stirring part connecting adjacent to the first stirring part. The first stirring part is arranged parallel to the axial direction of the refrigeration housing, and the second stirring part is arranged in a spiral shape between adjacent first stirring parts.

[0020] By adopting the above technical solution, the specific structure of the stirring blade is disclosed. The stirring blade is composed of the first stirring part and the second stirring part, which helps to stir the drinking water in multiple directions, improves the stirring efficiency, improves the cooling efficiency of the drinking water, and helps to scrape off the frost on the surface of the cooling shell, thus enhancing the cooling effect of the evaporator on the drinking water.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A refrigerator with an evaporator, wherein a refrigeration chamber between the evaporator and the mounting housing can be used to store drinking water, and a refrigeration assembly delivers cooling water from a cooling water tank to a refrigeration pipe through an inlet pipe and then outputs it through an outlet pipe, wherein the refrigeration pipe with a semi-elliptical cross-section and a refrigeration surface is fitted to the inner wall of the refrigeration housing, thereby increasing the contact area with the refrigeration housing and improving the refrigeration efficiency. 2. The inlet and outlet of the annular refrigeration branch pipe are axially symmetrically arranged, and the connecting pipe connects the outlet and inlet of the adjacent annular refrigeration branch pipe. This makes the cooling water flow more orderly in the refrigeration pipe, and can cool drinking water in the refrigeration chamber more efficiently, thus improving the refrigeration effect. 3. By setting up a stirring mechanism, the drinking water is stirred by a rotating shaft and stirring blades. The rotating shaft is set in a direction parallel to the axis of the refrigeration shell, which ensures that the refrigeration evaporator can be stirred evenly. The rotating shaft is set with a seal at the top of the refrigeration shell, which helps to enhance the sealing of the refrigeration chamber and reduce the risk of drinking water entering the evaporator.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a refrigerator with an evaporator. (Refer to...) Figure 1 and Figure 2 A refrigeration unit with an evaporator includes a mounting housing 1, a refrigeration evaporator 2 installed within the mounting housing 1, a cooling water tank 3 for holding cooling water, and a water outlet assembly 4 for discharging water. The mounting housing 1 is a hollow housing with a mounting chamber 11.

[0030] Reference Figure 2 and Figure 3 The evaporator 2 and the mounting housing 1 have a refrigeration chamber 12 for supplying drinking water. The evaporator 2 includes a refrigeration housing 21, a refrigeration assembly 22 mounted on the inner wall of the refrigeration housing 21, and a stirring mechanism 23 rotatably mounted on the refrigeration housing 21. The refrigeration assembly 22 includes a refrigeration pipe 221 that fits against the inner wall of the refrigeration housing 21, an inlet pipe 222 connected to the cooling water tank 3 for supplying cooling water to the refrigeration pipe 221, and an outlet pipe 223 for discharging cooling water from the refrigeration pipe 221. The inlet pipe 222 is connected to the top of the refrigeration pipe 221, and the outlet pipe 223 is connected to the bottom of the refrigeration pipe 221. The diameter of the inlet pipe 222 is larger than the diameter of the outlet pipe 223, so that the efficiency of water entering the refrigeration pipe 221 is always greater than the efficiency of water exiting, thereby ensuring that the refrigeration pipe 221 always has enough cooling water to cool the drinking water in the refrigeration chamber 12.

[0031] Reference Figure 3 and Figure 4 To improve the cooling effect of the refrigeration pipe 221 on the drinking water in the refrigeration chamber 12, the refrigeration pipe 221 has a semi-elliptical cross-section and a refrigeration surface 2211 that fits into the refrigeration housing 21. The refrigeration surface 2211 helps to increase the contact area between the refrigeration pipe 221 and the refrigeration housing 21, thereby more efficiently delivering cold air to the refrigeration chamber 12 to cool the drinking water. Furthermore, the refrigeration pipe 221 and the refrigeration housing 21 are integrally injection molded, which helps to improve the efficiency of cold air transmission, thus enhancing the cooling effect.

[0032] Reference Figure 3 and Figure 4 The refrigeration pipe 221 includes multiple annular refrigeration branch pipes 2212 axially arranged within the refrigeration housing 21 and connecting pipes 2213 connecting adjacent annular refrigeration branch pipes 2212. Each annular refrigeration branch pipe 2212 has an inlet 22121 and an outlet 22122 axially symmetrical to the inlet 22121. The connecting pipe 2213 connects the outlet 22122 of one annular refrigeration branch pipe 2212 to the inlet 22121 of an adjacent annular refrigeration branch pipe 2212. Furthermore, the connecting pipe 2213 is arranged perpendicular to the annular refrigeration branch pipes 2212, ensuring more uniform and stable cooling water delivery.

[0033] Reference Figure 3 and Figure 5 The stirring mechanism 23 is used to stir the drinking water in the refrigeration chamber 12, so that the drinking water can be cooled evenly and the cooling effect can be improved. The stirring mechanism 23 includes a rotating shaft 231 rotatably mounted on the refrigeration housing 21, stirring blades 232 mounted on the rotating shaft 231, and a rotation drive assembly 233 for driving the rotating shaft 231 to rotate. The extending direction of the rotating shaft 231 is parallel to the axial direction of the refrigeration housing 21. The stirring blades 232 include a first stirring part 2321 mounted on the rotating shaft 231 and circumferentially arranged on the outer wall of the refrigeration housing 21, and a second stirring part 2322 connecting adjacent first stirring parts 2321. The first stirring parts 2321 are arranged parallel to the axial direction of the refrigeration housing 21, and the second stirring parts 2322 are arranged spirally between adjacent first stirring parts 2321. In this embodiment, the stirring blades 232 include three first stirring parts 2321 and three second stirring parts 2322 connecting adjacent first stirring parts 2321.

[0034] Reference Figure 3 In order to reduce the probability of drinking water in the refrigeration chamber 12 entering the refrigeration housing 21, a seal 24 is provided between the rotating shaft 231 and the top of the refrigeration housing 21.

[0035] The implementation principle of a refrigerator with an evaporator in this application embodiment is as follows: During the refrigeration process of the refrigerator with an evaporator, cooling water is input from the cooling water tank 3 to the refrigeration pipe 221 through the water inlet pipe 222. The setting of the refrigeration surface 2211 in the refrigeration pipe 221 helps to increase the contact surface between the refrigeration pipe 221 and the refrigeration shell 21, thereby improving the cold air transfer efficiency. Furthermore, the setting of the stirring mechanism 23 stirs the drinking water in the refrigeration chamber 12, so that the drinking water in the refrigeration chamber 12 can be cooled evenly, further improving the refrigeration effect.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
