Description

Technical Field

[0001] The utility model relates to ice-making equipment, in particular to a cold energy recovery flowing water type ice tray and an ice maker. Background Art

[0002] Ice trays are commonly used in ice makers. An ice tray consists of ice cells, a bottom plate, and a refrigerant channel. Refer to Figure 1 , in the existing ice tray, the ice cells are fixed on the bottom plate. The ice cells are formed by inserting a number of horizontal bars and a number of vertical bars together to form a grid. Each horizontal bar and each vertical bar are welded to the bottom plate. The refrigerant channel 2 is fixed under the bottom plate. The aluminum profile refrigerant channel is formed by combining multiple groups of aluminum profiles. The bottom plate is fixed together with the refrigerant channel 2. The refrigerant flows in the flow channel formed by the bottom plate and the refrigerant channel 2 to provide cold energy for the water in the ice cells, so that the water in the ice cells freezes into ice cubes. This kind of ice tray has the following problems: First, due to the unreasonable setting of the flow channel of the refrigerant channel, the refrigerant operation is unreasonable, and there is a problem of uneven temperature up and down. The upper part of the ice cubes produced is full, and the lower part is incomplete, resulting in uneven ice making and uneven ice removal. Second, the ice removal is slow. Third, there is no cold energy recovery device. The ice maker includes a compressor, an ice tray, a circulating water tank, a circulating water pump, and a controller. The existing ice maker also has these problems, and the ice maker also has the problem of energy consumption. Summary of the Invention

[0003] An object of the utility model is to provide an aluminum alloy cold energy recovery flowing water type ice tray, which is used to solve the problems of uneven ice making and ice removal and slow ice removal in the existing technology of ice trays and ice makers; another object of the utility model is to provide an ice maker with an aluminum alloy cold energy recovery flowing water type ice tray.

[0004] The technical solution adopted by the utility model to solve its technical problems is: This aluminum alloy cold energy recovery flowing water type ice tray includes ice cells, a bottom plate, a refrigerant channel, and a cold energy recovery spray pipe. The ice cells of the ice tray are fixed on the bottom plate. The refrigerant channel is fixed on the back of the bottom plate. The refrigerant channel is fixed on the frame. The cold energy recovery spray pipe is horizontally installed at the upper frame of the frame. The bottom of the cold energy recovery spray pipe is evenly provided with water spray holes. The cold energy recovery spray pipe is installed close to the upper edge of the back surface of the refrigerant channel.

[0005] In the above solution, the initial flow channel connected to the refrigerant channel inlet pipe is the bottommost flow channel of the refrigerant channel. The tail of the initial flow channel bifurcates to form an upward shunt channel and a horizontal main channel. A throttling section with a reduced diameter is provided at the entrance of the shunt channel. The main channel and each of the upper flow channels form a serpentine flow channel that bends upward. When the serpentine flow channel reaches the tail of a flow channel adjacent to the bottom of the end flow channel connected to the outlet pipe, it converges with the shunt channel and goes upward to the uppermost flow channel. The uppermost flow channel and each of the lower rows of flow channels form a serpentine flow channel that bends downward until it is connected to the end flow channel.

[0006] In the above solution, a number of depressions are evenly arranged at the bottom of each flow channel of the refrigerant channel, and the bottom of each flow channel is a flow channel bottom with alternating convex and concave undulations.

[0007] In the above solution, the diameter of the throttling section of the shunt channel is 1 / 3 of the diameter of other parts of the shunt channel.

[0008] In the above solution, the depression is an elliptical depression, and each depression is arranged in an array.

[0009] An aluminum alloy cold energy recovery flowing water type ice tray ice maker includes an ice tray, a circulating water tank, a cold energy recovery solenoid valve, a water pump, and a controller. The ice tray is the aluminum alloy cold energy recovery flowing water type ice tray, and the aluminum alloy cold energy recovery flowing water type ice tray includes ice cells, a bottom plate, a refrigerant channel, and a cold energy recovery spray pipe; the circulating water tank is located directly below the ice tray, the cold energy recovery solenoid valve is connected to the cold energy recovery spray pipe through a water pipe, and the cold energy recovery solenoid valve is connected to the controller.

[0010] The utility model has the following beneficial effects:

[0011] The utility model is provided with a cold energy recovery spray pipe, which makes ice quickly and releases ice quickly. The cold energy recovery spray pipe is installed near the upper edge of the refrigerant channel. When releasing ice, water is sprayed out from the cold energy recovery spray pipe and then sprayed onto the upper end of the back surface of the refrigerant channel, flowing down along the refrigerant channel like a waterfall. The contact surface between the water flow and the entire back surface of the refrigerant channel is uniform. During the downward flow, the heat of the normal temperature water is conducted to the bottom surface of the ice cell, increasing the temperature of the bottom surface of the ice cell, and the ice cubes are quickly separated from the ice cell by heat, improving the ice release speed. The ice release time is about 1 minute earlier than that of the existing ice tray (without a cold energy recovery spray pipe); the water exchanges heat while flowing downward. When it flows into the circulating water tank under the ice tray, the water temperature decreases and becomes low-temperature water. When making ice, the water pump transports the low-temperature water from the circulating water tank to the water supply pipe that supplies water to the ice cells and flows into each ice cell. The time for the low-temperature water to freeze into ice cubes is 3 - 4 minutes less than the time for normal temperature water to freeze into ice cubes in the prior art, reducing production costs and energy consumption.

[0012] The refrigerant channel of the utility model is provided with a shunt channel and its throttling section with reduced diameter. When the refrigerant flows, while flowing upward in the lower flow channel, a small part of the refrigerant is diverted through the throttling section of the shunt channel and directly runs to the topmost flow channel, flowing downward. When the refrigerant reaches the flow channel below the last flow channel in the lower flow channel, it converges with the refrigerant in the shunt channel, and the two streams of refrigerant merge and continue to flow upward and then downward to the last flow channel. In this way, the refrigerant is reasonably distributed, the upper and lower parts are cold and the temperature is uniform during ice making, and the upper and lower parts are hot and the temperature is also uniform when releasing ice, thus realizing uniform ice making and uniform ice release.

[0013] 3. A number of depressions are evenly arranged at the bottom of each flow channel of the refrigerant channel of the present utility model. The bottom of each flow channel is a flow channel bottom with alternating convex and concave undulations. When the refrigerant runs in the flow channel, due to the alternating convex and concave undulations at the bottom of the flow channel, the refrigerant has fluctuations during operation, which stimulates an increase in the coldness of the refrigerant and improves the refrigeration efficiency.

Detailed Embodiment

[0024] The following further describes the present utility model with reference to the accompanying drawings:

[0025] Combined with Figures 2 - 6As shown in the figure, this aluminum alloy cold energy recovery flowing ice tray includes an ice grid 1, a bottom plate, a refrigerant channel 2, and a cold energy recovery spray pipe 3. The ice grid 1 of the ice tray is fixed on the bottom plate, the refrigerant channel 2 is fixed on the back of the bottom plate, the refrigerant channel 2 is fixed on the frame 4, the cold energy recovery spray pipe 3 is horizontally installed at the upper frame of the frame 4, and water spray holes are evenly arranged at the bottom of the cold energy recovery spray pipe 3. The cold energy recovery spray pipe 3 is installed close to the upper edge of the back of the refrigerant channel. When water sprays out from the cold energy recovery spray pipe 3, it just sprays onto the upper end of the refrigerant channel 2 and flows evenly downward from the upper end of the refrigerant channel. The length of the cold energy recovery spray pipe 3 is adapted to the width of the refrigerant channel 2. The water sprayed out from the cold energy recovery spray pipe 3 can cover the entire width of the refrigerant channel 2, that is, the water can completely cover the topmost flow channel of the refrigerant channel and flow evenly downward through the entire refrigerant channel.

[0026] In this embodiment (the first embodiment), the flow channel setting method of the refrigerant channel in the refrigerant channel in the prior art is adopted. The refrigerant runs in the flow channel. The refrigerant channel is an aluminum profile refrigerant channel, and the aluminum profile refrigerant channel is formed by stretching an aluminum plate with a wave shape. The back of the refrigerant channel is a smooth wave, which is the bottom of the flow channel of the refrigerant channel.

[0027] The second embodiment of the aluminum alloy cold energy recovery flowing ice tray of the present utility model is that the refrigerant channel is different from the refrigerant channel in the prior art. The flow channel setting method in the refrigerant channel is as follows: The initial flow channel 6 connected to the refrigerant channel inlet pipe 5 is the bottommost flow channel of the refrigerant channel. The tail of the initial flow channel 6 bifurcates to form an upward shunt channel 9 and a horizontal main flow channel 10. A throttling section 11 with a reduced diameter is provided at the inlet of the shunt channel 9. The diameter of the throttling section 11 is 1 / 3 of the diameter of other parts of the shunt channel 9. Of course, it can also be adjusted according to needs. The main flow channel 10 and each flow channel above it form a serpentine flow channel that bends upward. When the serpentine flow channel reaches the tail of a flow channel adjacent to the bottom of the end flow channel 8 connected to the outlet pipe 7, it converges with the shunt channel and goes upward to the topmost flow channel. The topmost flow channel and each row of flow channels below it form a serpentine flow channel that bends downward until it is connected to the end flow channel 8. When the refrigerant flows, while running upward in the lower flow channel, a small part of the refrigerant is shunted through the throttling section of the shunt channel 9 and directly runs to the topmost flow channel and runs downward. When the refrigerant runs in the lower flow channel to a flow channel below the end flow channel, it converges with the refrigerant in the shunt channel. The two streams of refrigerant merge together and continue to run upward and then downward to the end flow channel. When making ice, it is cold at the top and bottom, and the ice making is uniform. When de-icing, it is hot at the top and bottom, and the de-icing is uniform.

[0028] The difference between the third embodiment of the aluminum alloy cold energy recovery flowing ice tray of the present utility model and the first embodiment is as follows: A number of depressions 12 are evenly arranged at the bottom of each flow channel of the refrigerant channel. The bottom of each flow channel is a flow channel bottom with alternating convex and concave undulations. The depressions 12 are oval depressions, and each depression is arranged in an array. When the refrigerant runs in the flow channel, due to the bottom of the flow channel having alternating convex and concave undulations, the refrigerant has fluctuations during operation, which stimulates an increase in the coldness of the refrigerant and improves the refrigeration efficiency.

[0029] The difference between the fourth embodiment of the aluminum alloy cold energy recovery flowing ice tray of the present utility model and the first embodiment is as follows: A number of depressions are evenly arranged at the bottom of each flow channel of the refrigerant channel. The bottom of each flow channel is a flow channel bottom with alternating convex and concave undulations. The depressions are oval depressions, and each depression is arranged in an array. The initial flow channel 6 connected to the inlet pipe 5 of the refrigerant channel is the lowermost flow channel of the refrigerant channel. The tail of the initial flow channel 6 bifurcates to form an upward shunt channel 9 and a horizontal main flow channel 10. A throttling section 11 with a reduced diameter is provided at the entrance of the shunt channel 9. The main flow channel 10 and each of the flow channels above it form a serpentine flow channel that bends upward. When the serpentine flow channel reaches the tail of a flow channel adjacent to the bottom of the last flow channel 8 connected to the outlet pipe, it converges with the shunt channel and goes upward to the uppermost flow channel. The uppermost flow channel and each row of flow channels below it form a serpentine flow channel that bends downward until it is connected to the end flow channel 8.

[0030] Combined with Figures 7 - 9 As shown in the figure, an ice maker with an aluminum alloy cold energy recovery flowing ice tray includes an ice tray, a circulating water tank 13, a cold energy recovery solenoid valve 14, a water pump 15, and a controller. The ice tray is the aluminum alloy cold energy recovery flowing ice tray, which includes ice cells, a bottom plate, a refrigerant channel, and a cold energy recovery spray pipe; The circulating water tank 13 is located directly below the ice tray. The cold energy recovery solenoid valve 14 is connected to the cold energy recovery spray pipe 3 through a water pipe. The cold energy recovery solenoid valve 14 is connected to the controller. The circulating water tank 13 is connected to the water pump 15. The water pump 15 is connected to a water supply pipe through a water pipe. The water supply pipe is used to supply water to the ice cells to make ice cubes.

[0031] When this ice maker starts to make ice, normal temperature water is filled into the circulating water tank 13. The water pump 15 transports the normal temperature water from the circulating water tank 13 to the water supply pipe 16 and flows into each ice tray to make ice. When defrosting, the water is sprayed from the cold energy recovery spray pipe 3 and then onto the upper end of the back surface of the refrigerant channel, flowing down from top to bottom along the refrigerant channel like a waterfall. The water flow has a uniform contact surface with the entire back surface of the refrigerant channel. During the downward flow, the heat of the normal temperature water is conducted to the bottom surface of the ice tray, increasing the temperature of the bottom surface of the ice tray and causing the ice cubes to quickly separate from the ice tray due to heat, thus improving the defrosting speed. As the water flows downward, it exchanges heat. When it reaches the circulating water tank under the ice tray, the water temperature decreases and becomes low-temperature water. When making ice again, the water pump transports the low-temperature water from the circulating water tank to the water supply pipe and flows into each ice tray to make ice. Compared with the normal temperature water in the prior art, the low-temperature water freezes ice cubes faster and saves energy consumption. According to different types and directions of various ice trays, the position and angle of the cold energy recovery spray device can be adjusted to match the installation of the ice tray (the cold energy recovery spray device can be realized by a spray pipe or a method using multiple nozzles to achieve the cold energy recovery technology).

[0032] This ice maker mainly adopts the aluminum alloy cold energy recovery flowing water type ice tray provided by the present utility model and adds a cold energy recovery spray pipe, and other structures are the same as those in the prior art.

[0033] The present utility model solves the problem of cold energy loss and waste and also speeds up the ice-making speed. That is, when in the defrosting working state, the cold energy recovery solenoid valve is opened, and the water in the cold energy recovery spray pipe flows from top to bottom through the back surface of the refrigerant channel. The waves (depressions on the back of the refrigerant channel) increase the water area and also make the water flow in a disturbed state, fully contacting the back surface of the refrigerant channel and quickly exchanging cold energy, causing the water to quickly cool down and flow into the circulating tank for storage; at the same time, it causes the edges of the ice cubes to quickly melt and quickly defrost. When starting the ice-making working state, when making ice with the low-temperature water in the circulating water tank, the ice-making time is greatly reduced, achieving the purpose of quickly making ice.

[0034] The present utility model reduces the entire ice-making process by 3 minutes and improves the work efficiency by about 20%. At the same time, the cold energy recovery technology is suitable for the following types of ice cube ice makers, copper flowing water type ice tray ice makers, spray type ice tray ice makers, crescent type ice tray ice makers, bullet head type ice tray ice makers, aluminum die-cast ice tray ice makers, aluminum profile flowing water type ice tray ice makers, refrigerant channel stretching flowing water type ice tray ice makers, double-sided flowing water type ice tray ice makers, etc.
