Description

Technical Field

[0001] The invention relates to the technical field of ice making machines, in particular to a water pump for an ice making machine. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with the refrigerant in the refrigeration system. It uses a refrigeration system and water as a carrier to make ice when the power is on. Existing fully automatic commercial ice makers are generally composed of a refrigeration system consisting of a compressor, a condenser, an expansion valve or a capillary tube, and an ice tray, plus a water system consisting of a water tank, a water pump, a shunt pipe, a water pipe, etc., plus an ice storage bucket for storing ice cubes. The ice maker uses a water pump to pump water to the sprinkler head for ice making. Usually, ice makers use tap water directly to make ice.

[0003] Tap water often contains a variety of impurities, such as silt, clay and algae. If these impurities directly enter the ice maker and participate in the ice-making process, many problems will arise. Trace amounts of solid particle impurities such as silt and clay may gradually settle in the ice maker's pipes, valves, evaporator and other key components, reducing the ice maker's water supply efficiency and requiring maintenance and cleaning. At the same time, algae may breed and multiply in the humid environment of the ice maker, and their metabolites will contaminate the water used for ice making, causing the produced ice to have an odor and color, seriously affecting the quality of the ice and failing to meet the high-quality requirements of industries such as food processing and catering services.

[0004] To solve this problem, in the prior art, a filtering device is generally provided on the outside of the water pump to filter the tap water entering the water pump. It is necessary to find an additional suitable space outside the water pump to install the filtering device. The installation process of the external filtering device is relatively cumbersome. It needs to be connected to the water pump through connecting parts such as pipes and joints, which not only increases the workload and difficulty of installation, but may also cause problems such as water leakage due to improper connection. Moreover, due to the presence of a large number of external connecting pipes and joints, these components are prone to aging, loosening, leakage and other problems, and need to be regularly inspected and maintained, which increases the workload and cost of maintenance. The external filtering device usually needs to be cleaned or the filter element replaced separately, and the operation is relatively complicated, requiring maintenance personnel to spend more time and energy to operate, reducing maintenance efficiency.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example:

[0041] See also Figure 1-Figure 9The present invention provides a technical solution: a water pump for an ice maker, comprising a water pump body 1, the water pump body 1 is respectively provided with a water inlet end 2 and a water outlet end 3, an impeller rotating shaft 5 is movably installed inside the water pump body 1, an impeller 4 is fixedly installed on the impeller rotating shaft 5, a support rod 6 is fixedly installed on the water pump body 1, one end of the support rod 6 is connected to a connecting plate 11, a filter mesh 7 is arranged on the outer side of the connecting plate 11, a connecting cylinder 8 is arranged at one end of the connecting plate 11, an opening mechanism 9 is arranged on the outer side of the connecting cylinder 8, the opening mechanism 9 is fixedly connected to the filter mesh 7, and the filter mesh 7 has an opening state. As well as the closed state, in the expanded state, the filter mesh cloth 7 blocks the inner cavity. When the filter mesh cloth 7 is folded, it can be disassembled through the expanding mechanism 9. The filter mesh cloth 7 inside the water pump body 1 can have a more comprehensive filtering effect and can also save external space, thereby preventing the chance of water being exposed to the external environment, reducing the risk of being contaminated again, and reducing the maintenance of connecting parts. The filter mesh cloth 7 inside the water pump body 1 reduces the number of external connecting pipes and joints, reducing the risk of water leakage caused by loose and aging connecting parts, thereby reducing the maintenance workload of these parts.

[0042] In the overall structure, sealing rings are provided at all movable parts.

[0043] The filter cloth 7 can be a polyester fiber filter cloth (polyester fiber has high strength and wear resistance, good chemical stability, acid and alkali corrosion resistance, can adapt to the chemical environment of tap water, its fiber is relatively fine, can effectively intercept sand and clay particles, and also has a certain blocking effect on algae), polypropylene filter cloth (polypropylene filter cloth is a filter material with excellent performance, it is light, high strength, has good chemical corrosion resistance, and is relatively cheap, it has good hydrophilicity, can ensure that water passes through the filter cloth more smoothly, and can effectively capture impurities) and nylon filter cloth (nylon filter cloth has good wear resistance, corrosion resistance and high filtering accuracy, it has good elasticity, can resist the impact of water pressure to a certain extent without deformation, thereby ensuring the stability of the filtering effect, this material filter cloth can be repeatedly cleaned and used, and has a long service life).

[0044] In this embodiment, the expansion mechanism 9 includes a first support column 19, a second support column 20 and an inclined support column 22. The expansion mechanism 9 can be provided with several groups on the outside of the connecting tube 8 and distributed relatively symmetrically to ensure that after the expansion mechanism 9 expands the filter cloth 7, inside the water pump body 1, the outside of the connecting tube 8 is fixedly installed with a connecting ring plate 12, a first hinge seat 17 and a second hinge seat 18, the first support column 19 is arranged in the first hinge seat 17, the second support column 20 is arranged in the second hinge seat 18, the first support column 19 and the second support column 20 are in sliding contact, the first support column 19 can rotate the second support column 20 through the second hinge seat 18, and the filter cloth 7 bonded to the second support column 20 can be unfolded.

[0045] In this embodiment, the other side of the second support column 20 and the filter cloth 7 are bonded to each other, and the filter cloth 7 is wrapped around the outside of a plurality of second support columns 20 to ensure that the second support column 20 can drive the filter cloth 7 to open after being expanded.

[0046] When the opening mechanism 9 and the filter cloth 7 are in the folded state, their diameter is smaller than the channel diameter of the water inlet end 2 , so that the entire filter device is easy to take out from the water inlet end 2 .

[0047] In this embodiment, the diagonal support column 22 is in sliding contact with the first support column 19, and the bottom end of the diagonal support column 22 is fixedly connected to the first sliding plate 25, and a sliding block 24 is fixedly installed between two adjacent first sliding plates 25. The first push rod 23 and the second push rod 27 are fixedly installed on both sides of the bottom end of the sliding block 24. When the sliding block 24 moves, it can drive the diagonal support column 22 to move together. At the same time, when the diagonal support column 22 moves, it can drive the first support column 19 to rotate through the first hinge seat 17, and the angle between the first support column 19 and the connecting tube 8 can be adjusted by moving the sliding block 24.

[0048] In this embodiment, a first sliding groove 13 matching the first sliding plate 25 and a third sliding groove 26 matching the sliding block 24 are respectively provided in the connecting tube 8. The first sliding groove 13 and the third sliding groove 26 are interconnected. The length of the first sliding plate 25 is greater than the length of the third sliding groove 26. The first sliding plate 25 completely covers the outer side of the third sliding groove 26 to prevent tap water outside the connecting tube 8 from entering the connecting tube 8.

[0049] In this embodiment, a push plate 21 is fixedly installed on the other end of the first push rod 23, and a handle 14 is fixedly installed on the other end of the push plate 21. The handle 14 passes through the inner wall of the connecting tube 8 and extends outward. An anti-collision plate 10 is fixedly installed on the outer side of the connecting tube 8. The handle 14 is located on the inner side of the anti-collision plate 10, and the anti-collision plate 10 faces the water inlet end 2. The side of the anti-collision plate 10 facing the water inlet end 2 is set as an arc-shaped surface, which is convenient for tap water to enter the water pump body 1 through the water inlet end 2 to avoid the anti-collision plate 10 blocking the water flow. The width of the handle 14 is smaller than the anti-collision plate 10 to prevent the handle 14 from being impacted by the water flow.

[0050] When the handle 14 is used, a push handle is designed that can enter from the water inlet end 2 to push the handle 14. The push handle can be composed of a telescopic tube and a clip (both are existing mature technologies). The telescopic tube contacts the handle 14, and the clip is fixed on the flushing plate 10.

[0051] In this embodiment, a support frame 15 is fixedly installed inside the connecting tube 8, and a first extrusion spring 28 is arranged in the cavity between the push plate 21 and the support frame 15. The first push rod 23, the sliding block 24 and the second push rod 27 are all located in the cavity between the connecting tube 8 and the support frame 15, so as to ensure the stability of the push plate 21, the first push rod 23, the sliding block 24 and the second push rod 27 during movement, and present a linear motion, so as to prevent the push plate 21, the first push rod 23, the sliding block 24 and the second push rod 27 from position displacement during movement.

[0052] When in use, use the pushing handle to enter from the water inlet end 2 and push the handle 14. After the handle 14 is pushed, it will drive the pushing plate 21 to move toward the side of the support frame 15 and squeeze the first extrusion spring 28. At the same time, the pushing plate 21 will drive the first pushing rod 23 to move. When the first pushing rod 23 moves, it will drive the sliding block 24 to move in the third sliding groove 26. When the sliding block 24 moves, it will respectively drive the first sliding plate 25 and the second pushing rod 27 to move together. When the first sliding plate 25 moves, it will drive the diagonal support column 22 to move. After the diagonal support column 22 moves, it will lose support for the first support column 19, so that the first support column 19 will rotate on the first hinge seat 17 and attach to the outer side of the connecting tube 8, and at the same time lose support for the second support column 19. With the support of the support column 20, the second support column 20 will also rotate around the second hinge seat 18, and will drive the filter mesh 7 to shrink, driving the filter mesh 7 to shrink outside the connecting tube 8, so that the entire filter mechanism is in a contracted state, which is convenient for taking out from the water inlet end 2; on the contrary, after the filter mechanism enters the water pump body 1 through the water inlet end 2, the handle 14 moves in the opposite direction (i.e., moves toward the side of the anti-collision plate 10), the propping mechanism 9 will open, and the inclined support column 22 will drive the first support column 19 to rotate. When the first support column 19 rotates, it will drive the second support column 20 to rotate, and can drive the filter mesh 7 to open, so that the filter mesh 7 forms a filter mechanism between the water inlet end 2 and the water outlet end 3 to prevent the mud, clay and algae contained in the tap water from passing through.

[0053] See also Figure 10-12 The present invention provides a technical solution: in this embodiment, a fixing column 30 is fixedly installed on the outer side of the support frame 15, and a second extrusion spring 31 and a second sliding plate 32 are respectively sleeved on the outer side of the fixing column 30, the second extrusion spring 31 and the second sliding plate 32 are fixedly connected, and a pushing column 33 is fixedly installed on the side of the second sliding plate 32 facing the second extrusion spring 31, and the second pushing rod 27 is in contact with the second sliding plate 32.

[0054] In this embodiment, the interior of the connecting plate 11 is respectively provided with a second sliding groove 16 and a connecting groove, a partition 37 is fixedly installed in the connecting groove, a clamping column 35 and a piston block 36 are respectively provided on both sides of the partition 37, the connecting ring plate 12 and the piston block 36 are in contact through an inclined surface, and a sliding cavity 39 matching the clamping column 35 is provided in the connecting ring plate 12. The partition 37 does not divide the connecting groove into two independent parts, but divides it into two interconnected cavities to form a piston cavity. When the piston block 36 contacts the connecting ring plate 12, the piston block 36 will retract into the connecting groove and push the clamping column 35 into the sliding cavity 39 in the connecting ring plate 12, so that the connecting plate 12 is fixed in the connecting plate 11 through the clamping column 35, preventing the filter cloth 7 from failing to work normally in the water pump body 1.

[0055] In this embodiment, the other end of the clamping column 35 is fixedly installed with a third extrusion spring 38 and a pull rope 34, respectively. A sliding wheel 29 is provided in the second sliding groove 16. One side of the sliding wheel 29 contacts the pull rope 34, and the other side contacts the pushing column 33. When the pushing column 33 moves, it can drive the sliding wheel 29 to move in the second sliding groove 16, and when the sliding wheel 29 moves, it will drive the pull rope 34 to move together. Since the length of the pull rope 34 is fixed, when the pull rope 34 is driven by the sliding wheel 29, it will drive the clamping column 35 to slide out of the sliding cavity 39 in the connecting ring plate 12, so that the connecting ring plate 12 can be taken out from the connecting plate 11, thereby facilitating the connection tube 8 to be taken out from the connecting plate 11.

[0056] When in use, when the diagonal support column 22 and the first support column 19 are separated from each other, the second push rod 27 will contact the second sliding plate 32, and drive the second sliding plate 32 to slide on the fixed column 30, and squeeze the third extrusion spring 38. When the second sliding plate 32 moves, it will drive the pushing column 33 to move together. After moving, the pushing column 33 will enter the second sliding groove 16 and contact the sliding wheel 29, and will drive the sliding wheel 29 to move in the second sliding groove 16. When the sliding wheel 29 moves, it will drive the pull rope 34 to move together. When the pull rope 34 is subjected to tension, it will drive the clamping column 35 to disengage from the sliding cavity 39 in the connecting ring plate 12, so that the connecting ring plate 12 can be separated from the connecting plate 11. In this way, the connecting cylinder 8 can be disengaged from the connecting plate 11, which is convenient for the overall filter mechanism to be removed from the water pump body 1, so as to achieve the purpose of quick replacement of the filter mechanism.

[0057] After the entire filtering mechanism enters the water pump body 1, the connecting cylinder 8 is connected to the connecting plate 11 through the connecting ring plate 12, ensuring that the connecting cylinder 8 and the filter cloth 7 can be fixed inside the water pump body 1 and fully unfolded to achieve the filtering effect.

[0058] The working principle of this embodiment is as follows: use the pushing handle to enter from the water inlet end 2 and push the handle 14. After the handle 14 is pushed, it will drive the pushing plate 21 to move toward the side of the support frame 15 and squeeze the first extrusion spring 28. At the same time, the pushing plate 21 will drive the first pushing rod 23 to move. When the first pushing rod 23 moves, it will drive the sliding block 24 to move in the third sliding groove 26. When the sliding block 24 moves, it will respectively drive the first sliding plate 25 and the second pushing rod 27 to move together. When the first sliding plate 25 moves, it will drive the diagonal support column 22 to move. After the diagonal support column 22 moves, it will lose support for the first support column 19. In this way, the first support column 19 will rotate on the first hinge seat 17 and attach to the outer side of the connecting tube 8, and at the same time lose support for the first support column 19. The second support column 20 is supported by the second support column 20, so that the second support column 20 will also rotate around the second hinge seat 18, and will drive the filter mesh cloth 7 to shrink, and drive the filter mesh cloth 7 to shrink outside the connecting tube 8, so that the entire filter mechanism is in a contracted state, which is convenient for taking out from the water inlet end 2; on the contrary, after the filter mechanism enters the water pump body 1 through the water inlet end 2, the handle 14 moves in the opposite direction (i.e., moves toward the side of the anti-collision plate 10), the propping mechanism 9 will open, the inclined support column 22 will drive the first support column 19 to rotate, and when the first support column 19 rotates, it will drive the second support column 20 to rotate, and can drive the filter mesh cloth 7 to open, so that the filter mesh cloth 7 forms a filter mechanism between the water inlet end 2 and the water outlet end 3, preventing the mud, clay and algae contained in the tap water from passing through.

[0059] The second push rod 27 will contact the second sliding plate 32, and drive the second sliding plate 32 to slide on the fixed column 30, and squeeze the third extrusion spring 38. When the second sliding plate 32 moves, it will drive the push column 33 to move together. After moving, the push column 33 will enter the second sliding groove 16 and contact the sliding wheel 29, and will drive the sliding wheel 29 to move in the second sliding groove 16. When the sliding wheel 29 moves, it will drive the pull rope 34 to move together. When the pull rope 34 is subjected to tension, it will drive the clamping column 35 to disengage from the sliding cavity 39 in the connecting ring plate 12, so that the connecting ring plate 12 can be separated from the connecting plate 11. In this way, the connecting cylinder 8 can be disengaged from the connecting plate 11, which is convenient for the overall filtering mechanism to be removed from the water pump body 1, so as to achieve the purpose of quick replacement of the filtering mechanism.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
