Description

Technical Field

[0001] The utility model relates to the technical field of ice making, and more specifically, to a spherical flooded ice making evaporator and an ice maker. Background Art

[0002] With the popularity of cold drinks, ice makers, as devices for making ice cubes, are widely used. When making ice, the ice maker allows the refrigerant (i.e., the coolant) to exchange heat with room temperature water, thereby condensing the room temperature water into ice cubes. The ice cubes formed after condensation can be added to different beverages to meet the user's demand for cold drinks. Among them, spherical ice cubes have a unique appearance and cooling effect. They can rotate and melt better in beverages, keeping the beverages cool for a longer time while adding visual appeal. Currently, there is a lack of spherical evaporators in the market, so there is a lack of ice makers for making spherical ice. Generally, spherical ice is made by hand chiseling or by cutting other shaped ice cubes into spherical ice with a cutting machine. Summary of the Utility Model

[0003] To solve at least one aspect of the above problems, the utility model first provides a spherical flooded ice making evaporator, which includes a first housing and a second housing that are detachably connected to each other. The first housing and the second housing are covered to form a spherical ice making cavity. An internal flow channel for the refrigerant to flow through is provided in the second housing. An input pipe and an output pipe for the refrigerant to flow through are provided on the second housing, and both the input pipe and the output pipe are connected to the internal flow channel.

[0004] Optionally, the second housing includes an inner shell and an outer shell that are abutted and connected to each other. The internal flow channel is provided between the inner shell and the outer shell, and the ice making cavity is formed by covering the inner shell and the first housing.

[0005] Optionally, an exhaust port is provided on the side wall of the first housing. The exhaust port is connected to the ice making cavity and faces upward.

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description will be given to the specific embodiments of the present utility model with reference to the accompanying drawings.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship during the normal use of the product.

[0023] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the drawings of the embodiments of the present utility model, a coordinate system XYZ is set, where the positive direction of the X-axis represents the left side, the negative direction of the X-axis represents the right side, the positive direction of the Y-axis represents the front side, the negative direction of the Y-axis represents the rear side, the positive direction of the Z-axis represents the upper side, and the negative direction of the Z-axis represents the lower side.

[0024] An embodiment of the present utility model provides a spherical flooded ice making evaporator, in combination with Figures 1-5 As shown, it includes a first housing 1 and a second housing 2 that are detachably connected to each other. The first housing 1 and the second housing 2 are covered to form a spherical ice making cavity 3, and an inner flow channel 23 for refrigerant circulation is provided in the second housing 2.

[0025] In the spherical flooded ice making evaporator of the present utility model, a spherical ice making cavity 3 is formed by covering the first housing 1 and the second housing 2, and the refrigerant circulates in the second housing 2, so that the normal temperature water in the ice making cavity 3 is quickly cooled to form spherical ice. The user can separate the first housing 1 and the second housing 2 to take out the spherical ice cubes. Moreover, while the inner flow channel 23 is close to the ice making cavity 3, it does not occupy extra space, with a simple and ingenious structure, fast ice making speed, and convenient for users to use.

[0026] As Figure 2 The direction shown is the installation direction of the spherical flooded ice making evaporator. Both the first housing 1 and the second housing 2 are semi-circular in shape. The first housing 1 and the second housing 2 are pressed tightly by an external force to seal the ice making cavity 3 and prevent water leakage. The refrigerant circulates in the inner flow channel 23 through the compressor all the time.

[0027] The second housing 2 includes an inner housing 21 and an outer housing 22 that are abutted and connected to each other. The inner flow channel 23 is provided between the inner housing 21 and the outer housing 22. The ice-making cavity 3 is formed by covering the inner housing 21 and the first housing 1.

[0028] As Figure 3 shown, both the inner housing 21 and the outer housing 22 are semi-circular in shape, and the refrigerant flows between the inner housing 21 and the outer housing 22. The inner housing 21 and the outer housing 22 are abutted and connected, which is convenient for disassembly and cleaning during maintenance.

[0029] An input pipe 221 and an output pipe 222 for the refrigerant to flow through are provided on the second housing 2. Both the input pipe 221 and the output pipe 222 are communicated with the inner flow channel 23.

[0030] As Figure 1 shown, in this embodiment, the input pipe 221 is a copper pipe, and the output pipe 222 is a capillary copper pipe. Both the input pipe 221 and the output pipe 222 are welded to the outer housing 22, and the axis of the input pipe 221 is perpendicular to the axis of the output pipe 222. Both the input pipe 221 and the output pipe 222 are communicated with the inner flow channel 23, so that the refrigerant flows more evenly and stably in the inner flow channel 23.

[0031] The inner diameter of the capillary copper pipe is usually between 0.4 and 2.0 mm, and it is used to connect the condenser outlet and the evaporator inlet. The capillary copper pipe controls the amount of refrigerant entering the evaporator by restricting the flow path of the refrigerant liquid, causing a pressure drop during its flow. This pressure drop is achieved by changing the size of the capillary copper pipe. By adjusting the size of the capillary copper pipe, the pressure drop of the refrigerant flow can be changed, thereby controlling the flow rate.

[0032] An exhaust port 12 is formed on the side wall of the first housing 1. The exhaust port 12 is communicated with the ice-making cavity 3, and the exhaust port 12 faces upward.

[0033] As Figure 1 shown, when water changes from a liquid state to a solid state, the gas dissolved in the air separates from the water due to a sudden change in solubility, forming bubbles. These bubbles are trapped in the ice cubes, resulting in the ice cubes having bubbles and thus presenting a relatively turbid appearance. Setting the exhaust port 12 enables the gas generated during the ice-making process in the ice-making cavity 3 to be discharged through the exhaust port 12, so that the spherical ice produced has no bubbles and can present a transparent state, giving users a better visual experience. The structure is simple and ingenious. Setting the exhaust port 12 upward can prevent the liquid water from leaking out through the exhaust port 12.

[0034] A water inlet pipe 11 is provided on the first housing 1. The water inlet pipe 11 is communicated with the ice-making cavity 3.

[0035] As Figure 1As shown, in this embodiment, the water inlet pipe 11 and the input pipe 221 are both arranged parallel to the horizontal plane, and the water inlet pipe 11 is a silicone tube.

[0036] A first annular edge 13 protrudes from the first housing 1, and a second annular edge 211 protrudes from the second housing 2. The first annular edge 13 and the second annular edge 211 are in abutting connection.

[0037] As Figure 3 shown, the second annular edge 211 is provided on the inner housing 21. Setting the first annular edge 13 and the second annular edge 211 to abut against each other can make the structure more stable when the first housing 1 and the second housing 2 are pressed tightly.

[0038] A number of partition rings for guiding the flow of the refrigerant are provided on the inner flow channel 23, and flow ports for the refrigerant to flow through are provided on each of the partition rings.

[0039] As Figure 5 shown, the partition ring provided with the flow port is approximately C-shaped, and the refrigerant flows through each partition ring from right to left through different flow ports, so as to extend the time the refrigerant passes through the inner flow channel 23, so that the refrigeration cavity is cooled for a longer time and the ice-making effect is better.

[0040] There are four partition rings, which are the first partition ring 231, the second partition ring 232, the third partition ring 233 and the fourth partition ring 234 from right to left. There are four flow ports, which are the first flow port 235, the second flow port 236, the third flow port 237 and the fourth flow port 238 from right to left.

[0041] As Figure 5 shown, in this embodiment, the partition rings divide the inner flow channel 23 into four layers. The first partition ring 231, the second partition ring 232, the third partition ring 233 and the fourth partition ring 234 are coaxially arranged, with their lengths gradually decreasing and gradually moving away from the first housing 1 to adapt to the hemispherical shape of the second housing 2.

[0042] The first partition ring 231 and the right end wall of the second housing 2 cooperate to form a first flow area. The first partition ring 231 and the second partition ring 232 cooperate to form a second flow area. The second partition ring 232 and the third partition ring 233 cooperate to form a third flow area. The third partition ring 233 and the fourth partition ring 234 cooperate to form a fourth flow area. The fourth partition ring 234 and the left wall of the second housing 2 cooperate to form a fifth flow area. The refrigerant flows through the first flow area, the second flow area, the third flow area, the fourth flow area, and the fifth flow area in sequence from top to bottom, so as to extend the time the refrigerant stays in the inner flow channel 23 and make the ice-making effect of the inner cylinder better.

[0043] The first flow port 235 and the third flow port 237 are close to the lower end of the second housing 2, and the second flow port 236 and the fourth flow port 238 are close to the upper end of the second housing 2.

[0044] As Figure 5 shown, setting the positions of the flow ports in this way allows the refrigerant to fully flow through each separation ring, thereby further extending the residence time of the refrigerant in the internal flow channel 23 and making the ice-making effect of the refrigeration chamber better.

[0045] Another embodiment of the present invention provides an ice maker, including the spherical flooded ice-making evaporator as described above.

[0046] A bracket (not shown) and a screw structure (not shown) are provided in the ice maker, and the first housing 1 and the second housing 2 are installed in the ice maker through the bracket and the screw structure.

[0047] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
