Description

Technical Field

[0001] This invention relates to the field of snowflake ice maker technology, and specifically to a self-cleaning water-leaking structure for a snowflake ice maker. Background Technology

[0002] Currently, the self-cleaning structures of snow ice makers on the market vary. Some machines have spray pipes, water pumps, and water tanks inside to clean the machine by spraying, which is complex and costly. Others rely on manual water flushing to clean the machine, which is labor-intensive. Furthermore, the evaporator rotates continuously during cleaning, which can easily cause mechanical damage. If the machine is turned off for cleaning, the evaporator is difficult to clean.

[0003] For example, the utility model patent with patent publication number CN223056243U discloses a self-cleaning structure for a snowflake ice maker. This prior art adds a spray pipe, a water pump and a water tank inside the machine. During cleaning, the water pump draws water from the water tank and sprays it through the spray pipe to clean the evaporator components and the machine. Its structure is complex and greatly increases the cost of the equipment.

[0004] Therefore, there is still room for improvement and development in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a self-cleaning leak-proof structure for a snowflake ice maker. By setting an air inlet and an air inlet valve assembly, when cleaning is required, the air inlet valve assembly is controlled by a switch assembly to open the air inlet, and the gas enters the water storage chamber through the air inlet, so that the water in the water storage chamber can fall freely into the water storage box through the water outlet, thereby cleaning the water storage box, the evaporator assembly and the machine.

[0006] To achieve the above objectives, the technical solution applied in this invention is as follows: A self-cleaning leak-proof structure for a snowflake ice maker includes a water storage box containing an evaporator assembly; a water tank assembly positioned above the water storage box, with a water storage cavity formed within it, and a water outlet and an air inlet communicating with the water storage cavity, the water outlet corresponding to the water storage box; an air inlet valve assembly movably disposed within the air inlet, wherein when the air inlet valve assembly closes the air inlet, the water outlet is in a non-draining state, and when the air inlet valve assembly opens the air inlet, the water outlet is in a draining state; and a switch assembly for controlling the air inlet valve assembly to open or close the air inlet. This design, with its air inlet and air inlet valve assembly, allows for several temperature adjustments. During ice making, the air inlet is closed, preventing gas from entering the water storage chamber and thus preventing water from draining into the water storage box. When cleaning is required, the air inlet valve assembly is opened via a switch assembly, allowing gas to enter the water storage chamber and enabling water to flow freely into the water storage box through the outlet. This cleans the water storage box, evaporator assembly, and the machine itself. The design is simple and cost-effective.

[0007] According to the above scheme, the switch assembly includes a sliding switch, a switch bracket, and a pressure rod. The pressure rod is movably mounted on the water tank assembly, and a groove is formed inside the pressure rod. The switch bracket is slidably disposed within the groove, and the switch bracket and the air intake valve assembly are correspondingly arranged. The sliding switch is slidably disposed on the water tank assembly, and the sliding switch and the switch bracket are drively connected. The sliding switch is used to control the sliding displacement of the switch bracket, so that the switch bracket drives the air intake valve assembly to open or close the air intake. With this configuration, in the initial state, the air intake valve assembly closes the air intake. When the sliding switch is moved, causing the switch bracket to move below the air intake valve assembly, the switch bracket pushes the air intake valve assembly upward, thereby opening the air intake, which is convenient to operate.

[0008] According to the above scheme, the switching assembly includes a solenoid valve and a push rod, with the push rod and the intake valve assembly correspondingly arranged. The solenoid valve is used to control the lifting and lowering displacement of the push rod, so that the push rod drives the intake valve assembly to open or close the intake port. When the solenoid valve controls the push rod to rise, it can be used to push the intake valve assembly to open the intake port; when the solenoid valve controls the push rod to fall, the intake valve assembly resets and closes the intake port.

[0009] According to the above scheme, the sliding switch is provided with a sliding switch connecting rod, the water tank assembly is provided with a strip-shaped hole, the pressure rod is provided with a clearance notch, and the switch bracket is provided with a switch bracket connecting hole. The switch connecting rod passes through the strip-shaped hole and the clearance notch and is engaged with the switch bracket connecting hole, and the switch connecting rod is slidably configured with respect to the strip-shaped hole and the clearance notch. This configuration, by providing the strip-shaped hole and the clearance notch, allows the switch connecting rod to slide relative to the strip-shaped hole and the clearance notch when the sliding switch is toggled, thereby causing the switch bracket to slide.

[0010] According to the above scheme, the switch bracket is provided with a switch bracket inclined protrusion, and a pressure rod buckle is provided in the slide groove. The switch bracket inclined protrusion and the pressure rod buckle are correspondingly arranged. With this arrangement, when the switch bracket moves to below the intake valve assembly, the switch bracket pushes the intake valve assembly to rise. At this time, the switch bracket inclined protrusion and the pressure rod buckle are engaged and locked, which locks the switch bracket and the sliding switch, so that the air intake is always in the open state.

[0011] According to the above scheme, the water tank assembly is provided with spaced pressure rod limiting components and pressure rod mounting ribs. The first end of the pressure rod has a pressure rod mounting hole, which is hinged to the pressure rod mounting rib. The second end of the pressure rod has a pressure rod limiting block, which engages with the pressure rod limiting component. A spring is provided between the pressure rod limiting component and the pressure rod. With this configuration, the pressure rod is inclined under the elastic force of the spring. When the pressure rod is pressed to overcome the elastic force of the spring, the pressure rod causes the pressure rod buckle and the inclined protrusion of the switch bracket to disengage, thus releasing the switch bracket and the sliding switch.

[0012] According to the above scheme, the water tank assembly is provided with a switch bracket limiting component, and the switch bracket is provided with a switch bracket limiting groove. The switch bracket limiting groove and the switch bracket limiting component are slidably arranged, and a spring is provided between the switch bracket limiting groove and the switch bracket limiting component. With this arrangement, the switch bracket is in a misaligned state with the air intake valve assembly under the elastic force of the spring, which serves to limit the position of the switch bracket. When the sliding switch is moved to move the switch bracket below the air intake valve assembly, the spring is in a compressed state. When the sliding switch and the switch bracket are released, the sliding switch and the switch bracket can be quickly pulled back to their original positions under the rebound force of the spring.

[0013] According to the above scheme, the intake valve assembly includes an intake valve stem, a second sealing ring, and a second spring. The intake valve stem is slidably disposed inside the intake port, and the second sealing ring is fixed to the intake valve stem, sealing the intake port. The second spring is sleeved on the intake valve stem, with its two ends abutting against the intake valve stem and the intake port, respectively. In this configuration, in the initial state, the spring force of the second spring seals the second sealing ring against the intake port. When the intake valve stem rises and overcomes the spring force of the second spring, it causes the second sealing ring to disengage from the intake port, thereby opening the intake port. When the sliding switch and switch bracket disengage and release, the spring force of the second spring causes the intake valve stem to quickly reset the second sealing ring, rapidly closing the intake port.

[0014] According to the above scheme, the water storage box is provided with a water storage box rib, and a water outlet valve assembly is movably installed inside the water outlet nozzle. The water storage box rib and the water outlet valve assembly are correspondingly arranged. The water outlet valve assembly includes a water outlet valve rod, a spring, and a sealing ring. The water outlet valve rod is slidably disposed inside the water outlet nozzle, and the sealing ring is fixed to the water outlet valve rod, sealing the water outlet nozzle. The spring is fitted onto the water outlet valve rod, and the two ends of the spring abut against the water outlet valve rod and the water outlet nozzle, respectively. When the water tank assembly is installed on the machine, the water storage box rib on the water storage box pushes up the water outlet valve rod, overcoming the elastic force of the spring and causing the sealing ring to disengage from the water outlet nozzle, thereby opening the water outlet nozzle. When the water tank assembly is disassembled, the rebound force of the spring causes the water outlet valve rod to quickly reset the sealing ring, quickly closing the water outlet nozzle.

[0015] Beneficial effects of this invention: This invention is designed with an air inlet and an air inlet valve assembly. When cleaning is required, the air inlet valve assembly is controlled by a switch assembly to open the air inlet, allowing gas to enter the water storage chamber through the air inlet. This allows water in the water storage chamber to fall freely into the water storage box through the water outlet, thereby cleaning the water storage box, evaporator assembly, and machine. Its structure is simple and saves costs. Attached Figure Description

Detailed Implementation

[0018] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 15 As shown, the self-cleaning leak-proof structure of the snowflake ice maker of the present invention includes a water storage box 31, in which an evaporator assembly 35 is provided; a water tank assembly 34, which is located above the water storage box 31 and has a water storage cavity formed therein. The water tank assembly 34 is provided with a water outlet 9 and an air inlet 15 communicating with the water storage cavity. The water outlet 9 is correspondingly arranged with the water storage box 31; an air inlet valve assembly 7 is movably provided in the air inlet 15. When the air inlet valve assembly 7 closes the air inlet 15, the water outlet 9 is in a non-draining state. When the air inlet valve assembly 7 opens the air inlet 15, the water outlet 9 is in a draining state; and a switch assembly, which is used to control the air inlet valve assembly 7 to open or close the air inlet 15. This design, with its air inlet 15 and air inlet valve assembly 7, allows for several temperature adjustments. During ice making, the air inlet 15 is closed, preventing gas from entering the water storage chamber and thus preventing water from draining into the water storage box 31. When cleaning is required, the air inlet 15 is opened via a switch assembly, allowing gas to enter the water storage chamber and enabling water to flow freely into the water storage box 31 through the water outlet 9. This cleans the water storage box 31, the evaporator assembly 35, and the machine. The design is simple and cost-effective.

[0020] Among them, such as Figure 10 As shown, the water storage box 31 is provided with a water storage box overflow port 32, so that water can flow out through the water storage box overflow port 32 to clean other structures of the machine.

[0021] Among them, such as Figure 11 As shown, the lowest position of the water outlet 9 is lower than the position of the overflow port 32 of the water storage box and higher than the lowest position of the evaporator assembly 35, so that water can be contained in the water storage box 31 and soak the bottom of the evaporator assembly 35.

[0022] The water tank assembly 34 includes a water tank top cover 1, a water tank bottom cover 2, and a water tank outlet cover 3, which are fixedly connected from top to bottom. The air inlet 15 is located on the water tank bottom cover 2. The water tank outlet cover 3 has a columnar structure. The water outlet 9 is located on the bottom of the water tank outlet cover 3. The air inlet 15 is higher than the water outlet 9 to prevent water from overflowing.

[0023] Furthermore, the switch assembly includes a sliding switch 5, a switch bracket 17, and a pressure rod 22. The pressure rod 22 is movably mounted on the water tank assembly 34, and a groove is formed inside the pressure rod 22. The switch bracket 17 is slidably disposed within the groove, and the switch bracket 17 and the air intake valve assembly 7 are correspondingly arranged. The sliding switch 5 is slidably disposed on the water tank assembly 34, and the sliding switch 5 and the switch bracket 17 are drively connected. The sliding switch 5 is used to control the sliding displacement of the switch bracket 17, so that the switch bracket 17 drives the air intake valve assembly 7 to open or close the air intake port 15. This arrangement, as shown... Figure 13 As shown, in the initial configuration, the intake valve assembly 7 closes the intake port 15; as Figure 14 As shown, when the sliding switch 5 is turned and the switch bracket 17 is moved to the bottom of the intake valve assembly 7, the switch bracket 17 pushes the intake valve assembly 7 up, thereby opening the intake port 15, which is convenient to operate.

[0024] The water tank cover 1 is provided with a water tank brim 6. When the sliding switch 5 slides relative to the water tank brim 6, the air inlet valve assembly 7 is in the closed air inlet 15 state, which can be used for ice making. When it is moved in the opposite direction, the switch bracket 17 can be driven to push the air inlet valve assembly 7 to open the air inlet 15, which can be used for water dispensing from the water tank assembly 34, and can be used for water supply or cleaning the machine. That is, the water tank brim 6 can be used for a reminder function.

[0025] Furthermore, the sliding switch 5 is equipped with a sliding switch connecting rod 21, the water tank assembly 34 is equipped with a strip hole 14, the pressure rod 22 is equipped with a clearance notch 38, and the switch bracket 17 is equipped with a switch bracket connecting hole 19. The switch connecting rod 21 passes through the strip hole 14 and the clearance notch 38 and then engages with the switch bracket connecting hole 19, and the switch connecting rod 21 is slidably configured with respect to the strip hole 14 and the clearance notch 38. This configuration allows for... Figure 4 , 5 As shown in Figures 6 and 7, by setting the strip hole 14 and the clearance notch 38, when the sliding switch 5 is toggled, the switch linkage 21 can slide relative to the strip hole 14 and the clearance notch 38, thereby driving the switch bracket 17 to slide.

[0026] Furthermore, the switch bracket 17 is provided with a switch bracket inclined protrusion 20, and a pressure rod buckle 23 is provided in the slide groove. The switch bracket inclined protrusion 20 and the pressure rod buckle 23 are correspondingly arranged. This arrangement, as... Figure 9 , 14 As shown, when the switch bracket 17 moves below the intake valve assembly 7, the switch bracket 17 pushes the intake valve assembly 7 to rise. At this time, the switch bracket slant 20 and the pressure rod buckle 23 are locked together, which locks the switch bracket 17 and the sliding switch 5, so that the intake port 15 is always in the open state.

[0027] Furthermore, the water tank assembly 34 is provided with a pressure rod limiting member 12 and a pressure rod mounting rib 16 spaced apart. The first end of the pressure rod 22 is provided with a pressure rod mounting hole 24, which is hinged to the pressure rod mounting rib 16. The second end of the pressure rod 22 is provided with a pressure rod limiting block 25, which engages with the pressure rod limiting member 12. A spring 29 is provided between the pressure rod limiting member 12 and the pressure rod 22. This arrangement, as... Figure 9 As shown, the pressure rod 22 is inclined under the elastic force of the spring 3 29. When the pressure rod 22 is pressed to overcome the elastic force of the spring 3 29, the pressure rod 22 drives the pressure rod buckle 23 and the oblique protrusion 20 of the switch bracket to disengage, thereby releasing the switch bracket 17 and the sliding switch 5.

[0028] Furthermore, the water tank assembly 34 is provided with a switch bracket limiting member 13, and the switch bracket 17 is provided with a switch bracket limiting groove 18. The switch bracket limiting groove 18 and the switch bracket limiting member 13 are slidably disposed, and a spring 30 is provided between the switch bracket limiting groove 18 and the switch bracket limiting member 13. This arrangement, as... Figure 13 , 14 As shown, the switch bracket 17 is misaligned with the intake valve assembly 7 under the elastic force of the spring 30, which serves to limit the position of the switch bracket 17. When the slide switch 5 is toggled, the switch bracket 17 moves to below the intake valve assembly 7, the spring 30 is in a compressed state. After the slide switch 5 and the switch bracket 17 are released, the slide switch 5 and the switch bracket 17 can be quickly pulled back to their original positions under the rebound force of the spring 30.

[0029] Furthermore, the intake valve assembly 7 includes an intake valve stem 26, a second sealing ring 27, and a second spring 28. The intake valve stem 26 is slidably disposed within the intake port 15, the second sealing ring 27 is fixed to the intake valve stem 26, and the second sealing ring 27 is sealed to the intake port 15; the second spring 28 is sleeved on the intake valve stem 26, and both ends of the second spring 28 abut against the intake valve stem 26 and the intake port 15, respectively. This arrangement, as... Figure 9 As shown, in the initial state, the sealing ring 27 is sealed to the air inlet 15 under the elastic force of the second spring 28. When the air inlet valve rod 26 rises and overcomes the elastic force of the second spring 28, it drives the sealing ring 27 to disengage from the air inlet 15, thereby opening the air inlet 15. After the sliding switch 5 and the switch bracket 17 are released, the air inlet valve rod 26 drives the sealing ring 27 to quickly reset under the rebound force of the second spring 28, quickly closing the air inlet 15.

[0030] Furthermore, the water storage box 31 is provided with a water storage box rib 33, and a water outlet valve assembly 4 is movably provided inside the water outlet 9. The water storage box rib 33 and the water outlet valve assembly 4 are correspondingly arranged. The water outlet valve assembly 4 includes a water outlet valve rod 8, a spring 10, and a sealing ring 11. The water outlet valve rod 8 is slidably disposed inside the water outlet 9, and the sealing ring 11 is fixed on the water outlet valve rod 8. The sealing ring 11 and the water outlet 9 are sealed together. The spring 10 is sleeved on the water outlet valve rod 8, and the two ends of the spring 10 abut against the water outlet valve rod 8 and the water outlet 9, respectively.

[0031] The water tank assembly 34 is detachably installed on the machine. In its initial state, the water outlet valve assembly 4 closes the water outlet 9 to prevent water leakage. When the water tank assembly 34 is installed on the machine, the water outlet valve rod 8 is pushed up by the water storage box protrusion 33 on the water storage box 31, which overcomes the elastic force of the second spring 28 and drives the sealing ring 11 to disengage from the water outlet 9, thereby opening the water outlet 9. When the water tank assembly 34 is disassembled, the water outlet valve rod 8 drives the sealing ring 11 to quickly reset under the rebound force of the first spring 10, quickly closing the water outlet 9. Example

[0032] like Figure 15 As shown, the switching assembly includes a solenoid valve and a push rod 37, with the push rod 37 and the intake valve assembly 7 correspondingly arranged; the solenoid valve is used to control the lifting and lowering displacement of the push rod 37, so that the push rod 37 drives the intake valve assembly 7 to open or close the intake port 15.

[0033] The solenoid valve is installed inside the snow ice maker, and the push rod 37 is installed on the cover of the snow ice maker. When the solenoid valve controls the push rod 37 to rise, it can be used to push the air inlet valve assembly 7 to open the air inlet 15. When the solenoid valve controls the push rod 37 to fall, the air inlet valve assembly 7 resets and closes the air inlet 15.

[0034] The difference between this second embodiment and the first embodiment is that the switch assembly described in the first embodiment is a mechanical structure, while the switch assembly described in this second embodiment is an electric structure. The rest of the structure and principle are the same as those in the first embodiment, and will not be repeated.

[0035] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these modifications are within the scope of protection of the present invention.
