Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to an ice maker. Background Art

[0002] Ice makers use a refrigeration system and water as a carrier. When powered on, ice is produced by passing through a certain device. In the process of water freezing into ice, the gas dissolved in the water precipitates, forming many small bubbles. These bubbles scatter light, so the ice cubes you see are opaque. In order to prevent the influence of bubbles during the freezing process, the water is generally kept flowing so that the frozen ice cubes have a transparent appearance. The structure of the ice maker currently on the market to keep the water moving is generally to set a water paddle in the ice making chamber. The paddle stirs the water to drive the movement of the water. The structure is relatively complex, especially the dynamic sealing of the power output part of the paddle is difficult to achieve.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] like Figures 1 to 5 As shown, an embodiment of the utility model provides an ice maker, including an ice maker body 1, and arranged on the ice maker body 1: a water tank 2 for storing liquid water; an ice box 3, on which an ice making cavity 301 and an ice making assembly 31 extending into the ice making cavity 301 are provided; a water inlet pipe 4, connected between the water tank 2 and the ice box 3, and used for pumping water in the water tank into the ice making cavity 301; under normal operation, the water in the water tank 2 is pumped into the ice making cavity through the water inlet pipe 4, and when the specified water level is reached, water addition is stopped, and at this time the ice making assembly 31 works to form ice cubes of a specified shape in the ice making cavity.

[0028] In order to prevent the ice cubes from being opaque due to the problem of bubbles, the present solution further adds a circulation pipeline 5, which is connected between the ice box 3 and the water inlet pipeline 4, and is used to draw the liquid water in the ice making chamber 301 back to the water inlet pipeline 4, and then flow back from the water inlet pipeline 4 to the ice making chamber 301. The utility model provides an ice maker, which adds a circulation pipeline between the ice box and the water inlet pipeline, and draws the water in the ice box through the circulation pipeline and flows back to the ice making chamber to form an internal circulation, thereby ensuring the flow of water in the ice making chamber, and is not limited by the capacity of the ice making chamber. By adding the internal circulation, the bubbles in the liquid can be reduced when the ice making assembly makes ice, ensuring the production of transparent ice cubes. The overall structure of the present solution is simple, and no redundant moving parts are required, and the water body in the ice making chamber moves more fully.

[0029] In the embodiment of the utility model, in order to improve the effect of internal water flow, the communication port between the circulation pipeline 5 and the ice-making chamber 301 is close to the bottom of the ice-making chamber 301. When the circulation pipeline realizes internal circulation, it can drive the water near the bottom to flow, thereby driving the water flow in the entire ice-making chamber.

[0030] Furthermore, in the embodiment of the utility model, a diverter pipe 6 is further provided on the water outlet end of the water inlet pipe 4, and a plurality of water outlets 61 are provided on the diverter pipe 6. The diverter pipe 6 is located on the upper side of the ice-making chamber 301, and the plurality of water outlets 61 are all oriented toward the ice-making chamber 301. The structure is simple, and the water entering the ice-making chamber is diverted by the diverter pipe 6, thereby improving the effect of promoting the flow of water in the ice-making chamber.

[0031] Moreover, the water inlet pipeline 4 includes a first pipeline 41, a branch pipe 42 and a water inlet pipe 43, the first pipeline 41 is connected to the water tank 2 and the branch pipe 42, the water inlet pipe 43 is connected to the diverter pipe 6 and the branch pipe 42, and the circulation pipeline 5 is connected to the branch pipe 42. The structure is simple and can be improved on the existing structure. In this solution, the branch pipe 42 is a T-shaped three-way pipe.

[0032] Of course, the water inlet pipe 43 in this solution can also be the connecting end of the diverter pipe 6 , that is, the branch pipe 42 is directly connected to the diverter pipe 6 .

[0033] In addition, the branch pipe 42 of the present solution is close to the ice box 3, and through reasonable structural layout design, the total stroke of the internal circulation is shorter, thereby improving efficiency.

[0034] In the embodiment of the utility model, the specific structure of the circulation pipeline 5 is as follows: the circulation pipeline 5 includes a water pumping pipe 51 and a pump body 52, the water pumping pipe 51 extends into the ice-making chamber 301 and is close to the bottom of the ice-making chamber 301, and the pump body 52 is connected to the water pumping pipe 51 and the branch pipe 42. Moreover, in order to improve efficiency, the water outlet end of the pump body 52 is directly connected to the branch pipe 42.

[0035] In the embodiment of the utility model, the structure of the ice-making assembly 31 is as follows: the ice-making assembly 31 includes a condenser and a plurality of ice-making heads 311 arranged on the condenser and extending downward into the ice-making chamber 301, the plurality of ice-making heads 311 are arranged at intervals along the length direction of the ice-making box 3, the plurality of water outlets 61 on the diverter pipe 6 are arranged in a one-to-one correspondence with the number of the plurality of ice-making heads 311, and the water outlet directions of the plurality of water outlets 61 are arranged in a staggered manner with the plurality of ice-making heads 311. The function of the diverter pipe 6 in this scheme is to divert the water flow added to the ice-making chamber by the water inlet pipe, and also to promote the water drawn from the ice-making chamber in the internal circulation to flow back into the ice-making chamber, and the plurality of ice-making heads 311 are arranged in a staggered manner relative to the plurality of water outlets 61, that is, the plurality of water outlets 61 are respectively oriented toward the gaps between the plurality of ice-making heads 311, so that when the water outlet sprays water, the water flow between each ice-making head is driven to flow, thereby being able to more fully promote the water flow inside the ice-making chamber.

[0036] As one of the specific implementations but not limiting, Figure 5 As shown, the bottom of the ice-making chamber 301 is a curved surface, the water outlet 61 is located on one side of the curved surface, and the water outlet direction of the water outlet 61 is inclined downward and points to the direction extending along the surface of the curved surface. When water is sprayed out from the water outlet 61, it can move along the curved surface and form a circular flow that can be circulated from bottom to top, so that the movement of the water body is more complete and more sustainable.

[0037] In the embodiment of the utility model, like the traditional ice maker, the ice box 3 is rotatably arranged on the ice maker body 1. When ice making is completed, the ice box 3 is rotated to drive the ice cubes inside to be discharged. A rotating arm 302 is arranged on one side of the ice maker body 1. The rotating arm 302 is generally used to cooperate with the travel switch so that the ice box 3 can only rotate within a certain range to control the travel swing. In order to facilitate the setting of the circulation pipeline, the water pumping pipe 51 passes through the rotating arm 302 and extends into the ice making chamber 301. Specifically, a through hole is arranged on the rotating arm 302, and the through hole is arranged along the rotating shaft of the ice box 3. The present solution extends into the ice making chamber through the through hole, which does not affect the swing of the ice box 3 during normal operation. Of course, in order to ensure the sealing performance, the present solution can also achieve the above effect by arranging a rotary joint installed in the through hole at the water pumping pipe 51.

[0038] The utility model provides an ice maker, which adds a circulation pipeline between the ice box and the water inlet pipeline. The water in the ice box is pumped out through the circulation pipeline and flows back into the ice making chamber to form an internal circulation, thereby ensuring the flow of water in the ice making chamber and is not limited by the capacity of the ice making chamber. By adding the internal circulation, the bubbles in the liquid can be reduced when the ice making component makes ice, ensuring the production of transparent ice cubes. The overall structure of this solution is simpler, and no redundant moving parts are required, and the water in the ice making chamber moves more fully.
