Description

Technical Field

[0001] The utility model relates to the field of cooking equipment, in particular to an ice maker. Background Art

[0002] Current ice machines are usually equipped with a water tank with a water outlet at the bottom. A water pump is connected to the water outlet through a pipeline to pump water in the water tank to the ice making unit for ice making. However, in the process of using ice machines, in addition to using pure water to make ice, users also like to use beverages to make ice, such as orange juice. The coarse fiber solids such as fruit juice mixed in the beverage can easily cause the water pump to be blocked, resulting in damage to the ice machine. Utility Model Content

[0003] Therefore, an object of the present invention is to provide an ice maker to at least solve one of the problems existing in the above-mentioned prior art or related art.

[0004] One aspect of the utility model provides an ice-making machine, which includes: an ice-making unit; a liquid storage tank, a liquid outlet is provided at the bottom of the liquid storage tank; a pump body, connected to the liquid outlet, and used to pump the liquid in the liquid storage tank to the ice-making unit; a filter assembly, detachably arranged at the liquid outlet, the filter assembly includes a first filter screen and a second filter screen which are stacked, and the mesh number of the second filter screen is greater than the mesh number of the first filter screen.

[0005] The ice making machine provided in the embodiment of this aspect has a filter unit arranged at the liquid outlet, and the filter unit includes a first filter screen and a second filter screen which are stacked and distributed, so that the liquid in the liquid storage tank needs to pass through relatively sparse and relatively dense meshes before entering the pump body. The double-layer filtration can improve the filtering effect compared with the related art in which only a single-layer plastic filter screen is arranged at the liquid outlet, which is beneficial for filtering out coarse fiber solids in the liquid and reducing the probability of pump body clogging. In addition, by stacking the first filter screen and the second filter screen with different mesh sizes, it is beneficial for keeping the second filter screen in an open state, thereby improving the installation stability of the second filter screen.

[0006] In addition, the ice making machine provided in the above embodiment of the present application may also have the following additional technical features:

[0007] In some embodiments, the mesh number of the second filter is in the range of 80 to 100. The mesh of the second filter is small and dense, which can effectively filter the coarse fiber solids in the liquid to prevent the pump body from being blocked, and the mesh number of the second filter is not too high, which is convenient for production and processing.

[0008] In some embodiments, the first filter screen is a plastic screen, which has good corrosion resistance, low material cost and is easy to process.

[0009] In some embodiments, the second filter screen is a stainless steel screen, a nylon screen, or a PET screen. If the second filter screen is a stainless steel screen, it has good corrosion resistance and a certain strength, which is conducive to being firmly connected with the first filter screen. If the second filter screen is a nylon screen, it is not easy to corrode, and it is convenient to form a dense mesh, and the filtering effect is good. If the second filter screen is a PET (polyethylene terephthalate) screen, it has good corrosion resistance and is convenient to be firmly connected with the plastic second filter screen.

[0010] In some embodiments, the first filter screen and the second filter screen are connected together by secondary injection molding, which is conducive to firmly connecting the two together, preventing the second filter screen from sliding off the first filter screen, and ensuring the filtering effect.

[0011] In some embodiments, the second filter is disposed inside the first filter. The second filter is embedded in the first filter and is not exposed. On the one hand, the probability of the softer second filter being worn during the cleaning process can be reduced. On the other hand, even if the second filter is impacted by water flow, it will not be easily separated from the first filter or fall off the second filter, thereby improving the installation stability of the second filter.

[0012] In some embodiments, the second filter screen is disposed on one side of the first filter screen, so as to facilitate the connection of the two together and to facilitate the cleaning of coarse fiber solids and the like that clog the second filter screen.

[0013] In some embodiments, the filter assembly is detachably disposed inside the liquid storage tank. Compared with the case where the filter assembly is located outside the liquid storage tank, when the filter assembly needs to be removed, the user can directly reach into the liquid storage tank to remove the filter assembly, and the filter assembly is easy to disassemble and assemble.

[0014] In some embodiments, the liquid outlet is arranged near the bottom corner of the liquid storage tank, the filter assembly is in the shape of a housing, the filter assembly and the side wall and bottom wall of the liquid storage tank form a post-filtration space, and the liquid outlet is connected to the remaining space in the liquid storage tank through the post-filtration space, so as to ensure that the liquid in the liquid storage tank can enter the liquid outlet only after being filtered by the filter assembly.

[0015] In some embodiments, one of the sides of the filter assembly facing the liquid outlet and the wall of the liquid storage tank is provided with a mounting rod, and the other is provided with a mounting column, and the mounting column is pluggably mounted on the outside of the mounting rod.

[0016] In these embodiments, the filter assembly is installed in the liquid storage tank by inserting the installation column on the installation rod. The plug-in type disassembly and assembly method is convenient and quick. Moreover, when installing the filter assembly, the installation can be performed by aligning the positions of the installation rod and the installation column, which can ensure that the filter assembly is quickly installed in the specified position. In addition, the installation structure is simple and easy to process.

[0017] In some embodiments, the mounting rod is disposed on the bottom wall of the liquid storage tank, so that the user can insert the filter assembly roughly from top to bottom, which is easy to operate.

[0018] Furthermore, a limiting protrusion is provided on the side wall of the liquid storage tank, and the limiting protrusion is used to cooperate with the top limit of the filter assembly. The limiting protrusion can limit the upward movement of the filter assembly, thereby preventing the installation column and the installation rod on the filter assembly from being easily separated, and promoting the stable installation of the filter assembly in the liquid storage tank.

[0019] In some embodiments, the outer side of the filter assembly has a gripping portion, which bends and extends toward the inside of the liquid storage tank, so that the user can grab the gripping portion to take the filter assembly out of the liquid storage tank, which is easy to operate.

[0020] In some embodiments, a boss is provided on the bottom wall of the liquid storage tank at a position corresponding to the filter assembly, and the boss can extend into the bottom of the filter assembly and abut against the inner wall of the filter assembly. The design of the boss increases the flow path of the liquid into the post-filter space through the assembly gap between the filter assembly and the liquid storage tank, and can reduce the probability of the liquid entering the post-filter space and the pump body without being filtered.

[0021] Furthermore, a sink is provided on the boss, and the sink is laterally connected to the liquid outlet. Since the design of the boss will raise the bottom wall of the liquid storage tank at that location, which is not conducive to the low liquid level liquid entering the liquid outlet, therefore, a sink is provided on the boss so that the sink can extend laterally to the liquid outlet and be connected to the liquid outlet, so that the liquid with a low liquid level can enter the liquid outlet through the sink.

[0022] In some embodiments, the first filter screen and the second filter screen are connected together by a connecting piece, which is conducive to making the first filter screen and the second filter screen firmly connected.

[0023] Other aspects and / or advantages of the general inventive concept will be partially set forth in the following description, and some will be clear from the description or may be learned through implementation of the general inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In the current ice making machine, the bottom of the water tank has a water outlet, and the water pump is connected to the water outlet through a pipeline, and the water in the water tank is pumped to the ice making unit for ice making. During the ice making process, if the water tank stores beverages such as Orange Juice, the coarse fiber solids such as fruit pulp mixed in the beverage can easily cause the water pump to be blocked, resulting in damage to the water pump and the ice making machine. For this reason, the relevant technology proposes a solution of setting a filter net at the water outlet. The filter net is made of plastic and the mesh size is about 2mm. Although this filter net can prevent large solid particles from entering the water pump, the blocking effect is poor and the water pump still has the risk of clogging.

[0046] Based on this, the embodiment of the present application provides an ice maker that can reduce the probability of pump blockage. Figures 1 to 6 An ice making machine provided by an embodiment of the utility model is introduced.

[0047] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an ice-making machine, which includes an ice-making unit 10, a liquid storage tank 20 and a pump body 30. The ice-making unit 10 is used to make ice, the liquid storage tank 20 is used to store liquid, and the pump body 30 is used to pump the liquid in the liquid storage tank 20 to the ice-making unit 10, so that the ice-making unit 10 makes ice from the liquid. Specifically, a liquid outlet 210 is provided at the bottom of the liquid storage tank 20, and the pump body 30 is connected to the liquid outlet 210 through a pipe 310, so that the liquid in the liquid storage tank 20 is sucked through the liquid outlet 210.

[0048] The ice maker further includes a filter assembly 40 , which is disposed at the liquid outlet 210 . The filter assembly 40 includes a first filter screen 410 and a second filter screen 420 which are stacked. The mesh number of the second filter screen 420 is greater than the mesh number of the first filter screen 410 .

[0049] The ice maker provided in this embodiment is provided with a filter unit at the liquid outlet 210, and the filter unit includes a first filter screen 410 and a second filter screen 420 which are stacked and distributed, so that the liquid in the liquid storage tank 20 needs to pass through relatively sparse and relatively dense meshes before entering the pump body 30. The double-layer filtration can improve the filtering effect compared with the related art in which only a single-layer plastic filter screen is provided at the liquid outlet 210, which is beneficial for filtering out coarse fiber solids in the liquid and reducing the probability of clogging of the pump body 30.

[0050] Furthermore, the filter assembly 40 is detachably disposed at the liquid outlet 210. Since the filter assembly 40 has a good filtering effect, it will block coarse fiber solids such as fruit particles or other impurities during the filtering process. After long-term use, the filter assembly 40 is at risk of being blocked by coarse fiber solids or other impurities. Therefore, the filter assembly 40 is designed to be detachable, and the user can remove the filter assembly 40 to clean the blockage, and then install the filter assembly 40 to the liquid outlet 210 to restore its filtering function, or replace the filter assembly 40, to ensure the normal use of the ice maker and extend the service life of the ice maker.

[0051] Furthermore, the mesh number of the second filter screen 420 ranges from 80 meshes to 100 meshes. The mesh of the second filter screen 420 is very small and dense, and can effectively filter the coarse fiber solid matter in the liquid to prevent the pump body 30 from being blocked.

[0052] In a specific application, the mesh size of the second filter 420 can be 80 mesh, 85 mesh, 90 mesh or 98 mesh.

[0053] It should be noted that under the current production process, the second filter screen 420 with a mesh number of 80 to 100 can be processed, but if the mesh of the second filter screen 420 is thick, it cannot be processed to the above mesh number, and if the mesh number exceeds 100 mesh, it is difficult to process and shape. Therefore, the second filter screen 420 with a mesh number of 80 to 100 is very thin and easy to bend and deform. Therefore, in this embodiment, the second filter screen 420 is stacked with the first filter screen 410, which is conducive to keeping the second filter screen 420 in an open state, improving the installation stability of the second filter screen 420, and ensuring the filtering effect.

[0054] As an example, the first filter screen 410 is a plastic screen, which has good corrosion resistance, low material cost and is easy to process.

[0055] As an example, the second filter screen 420 is a stainless steel screen, which has good corrosion resistance and certain strength, and is conducive to being firmly connected with the first filter screen 410.

[0056] As an example, the second filter screen 420 is a nylon screen, which is not easy to corrode and can be easily processed to form dense meshes, thereby achieving good filtering effect.

[0057] As an example, the second filter screen 420 is a PET (polyethylene terephthalate) screen, which has good corrosion resistance and is convenient to be firmly connected with the plastic second filter screen 420 .

[0058] Regarding the connection method of the first filter 410 and the second filter 420, further, in some embodiments, the first filter 410 and the second filter 420 are connected together by injection molding. For example, secondary injection molding is conducive to firmly connecting the two together, preventing the second filter 420 from sliding off the first filter 410, and ensuring the filtering effect.

[0059] In a specific application, the first filter 410 can be a filter with a mesh size of about 2 mm in the related art, and the filter in the related art and the second filter 420 can be directly used for secondary injection molding, eliminating the need for additional design and processing of the first filter 410, which can save costs. Of course, the first filter 410 can also be redesigned and processed. The mesh size of the first filter 410 can range from 1.5 mm to 2.5 mm.

[0060] In other embodiments, the first filter screen 410 and the second filter screen 420 are connected together by a connecting member (not shown in the figure), which can also ensure that the first filter screen 410 and the second filter screen 420 are firmly connected.

[0061] As an example, the connecting piece may be a silicone clamping piece, which wraps around the periphery of the first filter screen 410 and the second filter screen 420 and clamps the two together tightly. Of course, adhesive may also be used to make the connection more secure.

[0062] As an example, the connecting member may also be a screw, which passes through the second filter 420 and is inserted into the first filter 410 .

[0063] Regarding the positional relationship between the first filter 410 and the second filter 420, further, in some embodiments, as Figure 2 As shown, the second filter 420 is arranged inside the first filter 410. The second filter 420 is embedded in the first filter 410 and is not exposed. On the one hand, the probability of the softer second filter 420 being worn during the cleaning process can be reduced. On the other hand, even if it is impacted by water flow, the second filter 420 will not be easily separated from the first filter 410 or fall off the second filter 420, thereby improving the installation stability of the second filter 420.

[0064] In specific applications, refer to Figure 2The mesh of the first filter 410 is the first mesh 411, and the mesh of the second filter 420 is the second mesh. When the pump body 30 sucks liquid, the liquid will first enter the first mesh 411 of the first filter 410 located on one side of the second filter 420, and then enter the second mesh of the second filter 420, and then flow out from the first mesh 411 of the first filter 410 located on the other side of the second filter 420. Coarse fiber solids can first enter the first mesh 411 of the first filter 410 located on one side of the second filter 420, and then be blocked by the second mesh of the second filter 420.

[0065] In other embodiments, the second filter screen 420 is disposed on one side of the first filter screen 410, so as to facilitate the connection of the two together and to facilitate the cleaning of the coarse fiber solids and the like that clog the second filter screen 420.

[0066] As an example, when the filter assembly 40 is located inside the liquid storage tank 20, the second filter screen 420 is arranged on the side of the first filter screen 410 away from the liquid outlet 210. In the process of the pump body 30 sucking liquid, the liquid will first impact the second filter screen 420, and the second filter screen 420 will preferentially block the coarse fiber solid matter, so that the coarse fiber solid matter can be blocked outside the filter assembly 40, which is convenient for subsequent cleaning of the filter assembly 40 to ensure its filtering capacity. Moreover, the second filter screen 420 will have a tendency to squeeze toward the first filter screen 410 under the impact of the liquid, which can reduce the probability of the second filter screen 420 being partially separated from the first filter screen 410 or even falling from the first filter screen 410, thereby improving the installation stability of the second filter screen 420.

[0067] As an example, when the filter assembly 40 is located inside the liquid storage tank 20, the second filter net 420 can also be located on the side of the first filter net 410 facing the liquid outlet 210. After the filter assembly 40 is installed in the liquid storage tank 20, the second filter assembly 40 is hidden, so the second filter net 420 will not be scratched when the liquid storage tank 20 is cleaned, and the second filter net 420 can be prevented from being worn or separated from the first filter net 410 when the user cleans the liquid storage tank 20.

[0068] Regarding the location of the filter assembly 40, further, in some embodiments, as Figure 1 and Figure 2 As shown, the filter assembly 40 is disposed inside the liquid storage tank 20. Compared with the filter assembly 40 being disposed outside the liquid storage tank 20, when the filter assembly 40 needs to be removed, since the opening of the liquid storage tank 20 is usually larger, the user can directly reach into the liquid storage tank 20 to remove the filter assembly 40, and the filter assembly 40 is easy to disassemble and assemble, and there is no need to worry about the problem of liquid leakage caused by the detachable filter assembly 40.

[0069] Of course, in other embodiments, the filter assembly 40 can also be arranged outside the liquid storage tank 20. For example, on the pipe 310 between the liquid outlet 210 and the pump body 30. In this way, when the user observes the liquid storage tank 20, the interior is relatively smooth and complete, and the filter assembly 40 does not need to occupy the internal space of the liquid storage tank 20, and it is not easy to hide dirt and dirt in the assembly gap. However, this requires that the liquid storage tank 20 is detachable from the body of the ice maker, so that it is convenient to carry the filter assembly 40 out, and remove the filter assembly 40 for cleaning or replacement. In addition, it is necessary to strengthen the sealing to prevent the liquid from overflowing through the assembly gap of the filter assembly 40 due to the detachability of the filter assembly 40.

[0070] In the case where the filter assembly 40 is disposed inside the liquid storage tank 20, the specific location and connection method of the filter assembly 40 are as follows: Figure 1 and Figure 2 As shown, the liquid outlet 210 is arranged near the bottom corner of the liquid storage tank 20, the filter assembly 40 is in the shape of a cover shell, and the filter assembly 40 and the side wall and bottom wall of the liquid storage tank 20 enclose a post-filtration space 260, and the liquid outlet 210 is connected with the remaining space in the liquid storage tank 20 through the post-filtration space 260. It can be ensured that the liquid in the liquid storage tank 20 can enter the liquid outlet 210 only after being filtered by the filter assembly 40. Moreover, the filter assembly 40 is in the shape of a cover shell, and the filtering area is large. Compared with the filter assembly 40 being arranged inside the liquid outlet 210, the filtering area is increased, and it can be ensured that a sufficient amount of liquid flows to the liquid outlet 210 after filtering while filtering.

[0071] In a specific application, the filter assembly 40 includes a filter body and support ribs 430 located on the periphery of the filter body, and the filter body and the support ribs 430 are surrounded by a cover shell with openings at the bottom and sides. The first filter 410 and the second filter 420 are both part of the filter body. The filter body is tilted in the liquid storage tank 20, and the support ribs 430 are supported on the wall surface of the liquid storage tank 20 and surround the liquid outlet 210. Among them, the support ribs 430 located at the bottom of the filter body extend vertically to fit the bottom wall of the liquid storage tank 20, and the support ribs 430 located at the top and both sides of the filter body extend horizontally to fit the side walls of the liquid storage tank 20. The support ribs 430 distributed circumferentially of the filter body form a circle and fully cover the liquid outlet 210 together with the filter body. Here, the filter body is tilted in the liquid storage tank 20, which can reduce the occupied area of ​​the filter assembly 40 on the bottom wall of the liquid storage tank 20, making it convenient for users to clean the liquid storage tank 20.

[0072] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, one side of the filter assembly 40 facing the liquid outlet 210 and the wall surface of the liquid storage tank 20 is provided with a mounting rod 220, and the other side is provided with a mounting column 440. The mounting column 440 is formed into a hollow sleeve shape, and the mounting column 440 is plugged into the outer side of the mounting rod 220. The filter assembly 40 is plugged into the mounting rod 220 through the mounting column 440, so as to be installed in the liquid storage tank 20. The plug-in disassembly and assembly method is convenient and quick. Moreover, when installing the filter assembly 40, the position of the mounting rod 220 and the mounting column 440 can be aligned for installation, which can ensure that the filter assembly 40 is quickly installed at the specified position. In addition, the installation structure is simple and convenient for processing.

[0073] As an example, one of the mounting column 440 and the mounting rod 220 is integrally formed with the first filter screen 410 of the filter assembly 40. The other of the mounting column 440 and the mounting rod 220 is integrally formed with the wall surface of the liquid storage tank 20. The processing is convenient and the connection is firm.

[0074] As an example, Figure 4 and Figure 6 As shown, there are two mounting posts 440 and mounting rods 220, which are connected one by one, and the connection is stable and easy to plug and unplug. Of course, the number of mounting posts 440 and mounting rods 220 can be three or more, and the filter assembly 40 is installed in the liquid storage tank 20 at multiple points, and the installation stability is good.

[0075] As an example, Figure 2 and Figure 6 As shown, when the filter assembly 40 includes a filter body and a support rib 430 located on the periphery of the filter body, the mounting post 440 is connected to the back of the filter body, such as integral injection molding, and the connection is firm, especially when the filter assembly 40 is pressed downward to make it plug-in connected to the mounting rod 220, the probability of the mounting post 440 breaking can be reduced. Alternatively, the mounting post 440 and the support rib 430 are connected together by reinforcing ribs. At this time, a gap can be provided between the mounting post 440 and the filter body, so that the mesh is distributed over a large area on the filter body without having to avoid the mounting post 440, thereby increasing the filtering amount. Alternatively, the mounting post 440 is connected to the back of the filter body and the support rib 430 at the same time, thereby increasing the installation stability of the mounting post 440.

[0076] In a specific embodiment, Figure 2 and Figure 3 As shown, the mounting rod 220 is disposed on the bottom wall of the liquid storage tank 20. The user can insert the filter assembly 40 generally from top to bottom, which is easy to operate.

[0077] like Figure 2 , Figure 3 and Figure 4As shown, a limiting protrusion 230 is provided on the side wall of the liquid storage tank 20, and the limiting protrusion 230 is used to cooperate with the top of the filter assembly 40. The limiting protrusion 230 can limit the upward movement of the filter assembly 40, thereby preventing the installation column 440 on the filter assembly 40 from being easily separated from the installation rod 220, and promoting the stable installation of the filter assembly 40 in the liquid storage tank 20.

[0078] As an example, the limiting protrusion 230 is a convex bump or a convex rib, which is integrally formed with the side wall of the liquid storage tank 20 and has a simple structure.

[0079] Of course, in another specific embodiment, the mounting rod 220 may also be disposed on the side wall of the liquid storage tank 20, so that the user can roughly horizontally insert the filter assembly 40. In this case, the limiting protrusion 230 may be disposed on the bottom wall of the liquid storage tank 20, and cooperate with the end of the bottom of the filter assembly 40 away from the liquid outlet 210 to prevent the filter assembly 40 from moving outward horizontally.

[0080] Furthermore, in some embodiments, Figure 2 , Figure 5 and Figure 6 As shown, the outer side of the filter assembly 40 has a gripping portion 450. When the filter assembly 40 is disposed inside the liquid storage tank 20, the gripping portion 450 bends and extends toward the inside of the liquid storage tank 20. It is convenient for the user to grab the gripping portion 450 to take the filter assembly 40 out of the liquid storage tank 20, and the operation is convenient.

[0081] Of course, when the filter assembly 40 is disposed outside the liquid storage tank 20 , the gripping portion 450 may be bent and extended in a direction away from the liquid storage tank 20 .

[0082] Further, in some embodiments, when the filter assembly 40 is disposed inside the liquid storage tank 20, as shown in FIG. Figure 3 and Figure 4 As shown, a boss 240 is provided on the bottom wall of the liquid storage tank 20 at a position corresponding to the filter assembly 40, and the boss 240 can extend into the bottom of the filter assembly 40 and abut against the inner wall of the filter assembly 40. The design of the boss 240 increases the flow path of the liquid into the post-filter space 260 through the assembly gap between the filter assembly 40 and the liquid storage tank 20, and can reduce the probability of the liquid entering the post-filter space 260 and entering the pump body 30 without being filtered.

[0083] Furthermore, if Figure 3 and Figure 4As shown, a sink 250 is also provided on the boss 240, and the sink 250 is laterally connected to the liquid outlet 210. Since the design of the boss 240 will raise the bottom wall of the liquid storage tank 20 at that location, which is not conducive to the low liquid level liquid entering the liquid outlet 210, the sink 250 is provided on the boss 240 so that the sink 250 can extend laterally to the liquid outlet 210 and communicate with the liquid outlet 210, so that the liquid with a low liquid level can enter the liquid outlet 210 through the sink 250.

[0084] In other embodiments, the position on the bottom wall of the liquid storage tank 20 corresponding to the filter assembly 40 can be recessed, the bottom wall of the liquid storage tank 20 can be partially recessed, and the bottom of the outer wall of the filter assembly 40 can be matched with the recessed limiter, so that the setting of the trough 250 can be avoided, thereby achieving a technical effect similar to the above.

[0085] Furthermore, in some embodiments, Figure 1 As shown, the ice maker further includes an ice storage bin 50, which is connected to the ice making unit 10 and is used to store ice cubes made by the ice making unit 10. The ice storage bin 50 is arranged on the top of the liquid storage tank 20, and the bottom of the ice storage bin 50 has an ice water outlet, so that ice water melted from the ice cubes can flow into the liquid storage tank 20 through the ice water outlet. Not only can resource recycling be achieved, but the ice water can also reduce the temperature of the liquid inside the liquid storage tank 20, which is conducive to the ice making unit 10 to make ice quickly and save energy.

[0086] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
