Description

Technical Field

[0001] This utility model relates to the technical field of ice makers, specifically to an ice maker with a cold water tank. Background Technology

[0002] An ice maker is a refrigeration machine that produces ice by cooling water through an evaporator with a refrigerant in a refrigeration system.

[0003] Existing ice makers typically have only a single water tank, which directly supplies water to the ice-making mechanism to complete the ice-making process. However, because the water temperature in the tank is relatively high, the temperature of the residual cold water generated during the ice-making process will rise if it is directly returned to the tank. This means that the residual cold water generated during the previous ice-making process cannot be efficiently utilized in the next ice-making cycle, which is not conducive to improving the energy efficiency of the ice maker.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an ice maker with a cold water tank, which can reduce the water temperature in the circulating water tank, thereby improving the ice-making efficiency of the inner tank and improving the energy efficiency of the ice maker.

The joint part is connected and cooperated with the spiral ice pushing channel and the lower position of the upper side of the circulating water tank, respectively.

[0012] As a specific embodiment, the bottom inner side of the circulating water tank is provided with a water outlet, which is connected to a cold water pump.

[0019] Figure 2 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figure 1 , Figure 2This ice maker with a cold water tank includes a circulating water tank 2 and an inner tank 3. The inner tank 3 is equipped with an ice-making mechanism capable of making ice cubes. A first water supply channel is provided between the circulating water tank 2 and the inner tank 3 to allow liquid to be transferred from the circulating water tank 2 to the inner tank 3. A second water supply channel is also provided between the inner tank 3 and the circulating water tank 2 to allow liquid to be transferred from the inner tank 3 to the circulating water tank 2. By setting up the circulating water tank 2, the residual cold water generated during the ice-making process of the inner tank 3 can enter the circulating water tank 2. During continuous ice making, the water temperature entering the inner tank 3 can be relatively reduced, thereby improving the ice-making efficiency of the inner tank 3 and improving the energy efficiency of the ice maker.

[0022] Furthermore, the circulating water tank 2 is located below the bottom of the inner tank 3. A connector 4 is provided between the lower side of the inner tank 3 and the upper side of the circulating water tank 2. The connector 4 is connected to both the inner tank 3 and the circulating water tank 2. A second water supply channel is formed in the connector 4. The residual cold water generated by the inner tank 3 can directly enter the circulating water tank 2 through the connector 4 by gravity, without the need for additional water supply equipment, thus reducing the material cost of the equipment.

[0023] Furthermore, the inner liner 3 has an ice outlet 31. The ice-making mechanism includes a spiral ice pusher 51 and a drive motor 52 for driving the spiral ice pusher 51 to rotate. The spiral ice pusher 51 is located at the bottom of the inner liner 3 and is inclined downwards away from the ice outlet 31. A spiral ice pushing channel 32 is formed at the bottom of the inner liner 3 corresponding to the position of the spiral ice pusher 51. The spiral ice pushing channel 32 is inclined downwards away from the ice outlet 31. The spiral ice pushing channel 32 can relatively increase the ice storage capacity at the bottom of the inner liner 3, allowing the spiral ice pusher 51 to push more ice blocks simultaneously. The spiral ice pusher 51 pushes the ice blocks towards the ice outlet 31 by pushing them.

[0024] Furthermore, the ice-making mechanism also includes an ice-making box 53 and an ice-making evaporator 54 disposed inside the ice-making box 53. The water inlet end of the inner liner 3 is connected to the ice-making box 53. The ice-making box 53 is located above the spiral ice-pushing channel 32, so that the ice blocks produced by making ice blocks and the remaining cold water can directly enter the spiral ice-pushing channel 32 by gravity.

[0025] Furthermore, the upper side of the circulating water tank 2 is inclined downward along the direction away from the ice outlet 31 and is arranged adjacent to the spiral ice pushing channel 32. The connector 4 is connected and cooperated with the spiral ice pushing channel 32 and the lower position of the upper side of the circulating water tank 2 respectively. The circulating water tank 2 can utilize the shape of the spiral ice pushing channel 32 to achieve the effect of relatively increasing its own volume, and better utilize the space inside the ice maker.

[0026] Furthermore, the bottom inner side of the circulating water tank 2 is provided with an outlet 22, which is connected to a cold water pump 6. The cold water pump 6 is connected to the outlet 22 and the inlet of the inner tank 3 through a pipe to form a first water supply channel, which facilitates the control of the water flow state between the circulating water tank 2 and the inner tank 3.

[0027] Furthermore, the circulating water tank 2 is connected to the water storage tank 1. A third water supply channel is provided between the water storage tank 1 and the circulating water tank 2 to allow liquid to be transferred from the water storage tank 1 to the circulating water tank 2. The water storage tank 1 can supply water to the circulating water tank 2 through the third water supply channel to ensure that the circulating water tank 2 has enough water to supply the inner tank 3.

[0028] Furthermore, a water inlet 21 is provided on the circulating water tank 2 at a position adjacent to the connector 4. The water outlet of the storage tank 1 and the water inlet 21 are connected through the water conveying device 7 to form a third water conveying channel, which facilitates the control of the water flow state between the storage tank 1 and the circulating water tank 2. Moreover, a certain height difference is formed between the water inlet 21 and the bottom of the circulating water tank 2, which can reduce the chance of cold water flowing back into the third water conveying channel.

[0029] Furthermore, the circulating water tank 2 is equipped with a water level monitoring device 8, which is electrically connected to an electronic control device. The electronic control device is electrically connected to the first water supply component 7 and the cold water pump 6. The electronic control device can determine the water volume in the circulating water tank 2 based on the water level monitoring device 8, and control the working status of the water supply component 7 and the cold water pump 6 to keep the water volume in the circulating water tank 2 within a more reasonable range, so that the temperature of the cold water entering the inner tank 3 can be relatively more stable.

[0030] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
