Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a drainage system and an ice maker. Background Technology
[0002] An ice maker is a refrigeration machine that produces ice by passing water through an evaporator and cooling it with a refrigerant from a refrigeration system. It is widely used in the food manufacturing and catering industries.
[0003] The basic principle of an ice maker is to inject an appropriate amount of liquid water into the water tank for pre-cooling, and then use a water pump to transport the liquid water to the evaporator. Under the action of a cold medium, the liquid water freezes into ice cubes, which are then de-iced and stored in an ice storage box. To ensure food safety, the ice maker needs to have its drain device turned on periodically during use to clean the water tank. It also needs to be rinsed and drained after prolonged storage or when a new machine is first used.
[0004] Existing drainage systems typically use water pumps to drain water from the collection box, which not only involves numerous parts and high costs but also requires complex assembly processes. Furthermore, when power is lost during use, the water pump cannot operate, and the melted ice water will overflow from the ice storage box, soaking surrounding electronic components. If power is restored, this can easily cause a short circuit hazard. Utility Model Content

[0048] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0049] This embodiment provides a drainage system that can be used to drain the water collection box and ice storage basket inside an ice maker. For example... Figure 1 As shown, the drainage system includes a housing 1, a water receiving box 2, an ice storage basket 3, an outlet pipe 4, and a drainage assembly 5.
[0050] In the flow path of liquid water within the ice maker, the water receiving box 2 is located upstream of the ice storage basket 3. Liquid water in the ice maker's water tank is pre-cooled by the water receiving box 2 and then transported to the evaporator. Finally, under the action of the refrigerant, it solidifies into ice blocks, which are then stored in the ice storage basket 3. In this embodiment, both the water receiving box 2 and the ice storage basket 3 are located within the housing 1, making the overall structure of the drainage system compact and space-saving.
[0051] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an opening 15 is formed on one side of the cabinet 1, through which the ice storage basket 3 can be pulled out and out of the cabinet 1 for easy access to ice by the user. A water collection box 2 is located on the side wall away from the opening 15 of the cabinet 1, and is staggered vertically and / or longitudinally from the ice storage basket 3. It is understood that in actual use, the water collection box 2 is usually positioned higher than the ice storage basket 3, and is further away from the opening 15 of the cabinet 1 than the ice storage basket 3, to avoid structural interference.
[0052] To be more specific, refer to Figure 2 and Figure 4 The inner walls on both sides of the opening 15 of the housing 1 are respectively provided with grooves 16, and the ice storage basket 3 is provided with protrusions 34 on both sides corresponding to the grooves 16. The protrusions 34 are slidably connected to the grooves 16. By sliding the protrusions 34 in the grooves 16, the movement of the ice storage basket 3 can be guided and limited when it is pulled out, thereby improving the smoothness of pulling out the ice storage basket 3.
[0053] More specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, a first protrusion 161 is formed upward at the end of the chute 16 near the opening 15, and a second protrusion 341 is formed downward on the rib 34. The first protrusion 161 is used to cooperate with the second protrusion 341 when the ice storage basket 3 is pulled out to prevent the ice storage basket 3 from being pulled out as a whole, so that the ice storage basket 3 is stuck in a reliable position, thereby facilitating ice retrieval.
[0054] It is understandable that during the pulling process of the ice storage basket 3, some ice will melt into water, resulting in water accumulation at the bottom of the ice storage basket 3. The water accumulation will accelerate the melting of ice, and prolonged water accumulation can easily breed bacteria, affecting food safety. Therefore, a drainage hole 32 is provided on the ice storage basket 3 to drain the water inside the ice storage basket 3.
[0055] Specifically, such as Figures 4-7 As shown, a water storage tank 11 is provided on the bottom wall of part of the box 1, and a drain hole 32 can be selectively connected to the water storage tank 11. When the ice basket 3 is pushed into the box 1, the drain hole 32 can be connected to the water storage tank 11, so that the water from the melting ice in the ice basket 3 can be drained into the water storage tank 11. When the ice basket 3 is pulled out of the box 1 and ice is taken out, the drain hole 32 is blocked and not connected to the water storage tank 11, so as to effectively prevent water leakage.
[0056] For more specific details, please refer to [the relevant documentation / reference]. Figure 4 and Figure 7 The bottom wall of the other part of the box 1 is a supporting part 12. The bottom of the water storage tank 11 is lower than the supporting part 12 in the vertical direction. The ice storage basket 3 is placed on the supporting part 12, which provides stable support for the ice storage basket 3. In this embodiment, the supporting part 12 is the bottom wall of the box 1, and the water storage tank 11 is formed by protruding downward from the bottom wall of the box 1. The supporting parts 12 on both sides of the water storage tank 11 together form a placement plane for placing the ice storage basket 3. Of course, in other embodiments, the bottom of the water storage tank 11 can also be used as the bottom wall of the box 1, and the supporting part 12 can be a placement platform protruding on both sides of the water storage tank 11, with the tops of the two placement platforms flush, for placing the ice storage basket 3.
[0057] More specifically, the drain hole 32 is formed through the bottom wall or side wall of the ice storage basket 3, which is directly opposite the water storage tank 11. In this embodiment, the side wall of the ice storage basket 3 is recessed inward to form a receiving groove 31. The vertical projection of the receiving groove 31 falls into the water storage tank 11. The bottom end of the receiving groove 31 penetrates the bottom wall of the ice storage basket 3 and communicates with the water storage tank 11. The drain hole 32 is formed at the bottom of the receiving groove 31. This arrangement ensures that the water flowing out of the drain hole 32 can directly flow into the water storage tank 11.
[0058] More specifically, such as Figure 6 As shown, the ice storage basket 3 also includes a drain plug 33, which can be inserted and removed to seal the drain hole 32. A clamping plate 311 is connected to the side wall of the receiving groove 31. The clamping plate 311 is parallel to and spaced apart from the top wall of the receiving groove 31. The drain plug 33 includes a sealing part 331 and a holding part 332. The sealing part 331 is used to seal the drain hole 32. The holding part 332 is connected to one end of the sealing part 331 and can be locked between the clamping plate 311 and the top wall of the receiving groove 31.
[0059] During normal ice-making, open the drain plug 33 and secure the handle 332 of the drain plug 33 between the clamp 311 and the top wall of the receiving groove 31 to prevent the drain plug 33 from being lost. At this time, the water from the melting ice in the ice storage basket 3 will drain through the drain hole 32 into the water storage tank 11 at the bottom of the box 1. When removing the ice from the ice storage basket 3, remove the drain plug 33 and insert the sealing part 331 into the drain hole 32 to seal the drain hole 32, so as to prevent the water in the ice storage basket 3 from leaking onto the ground and causing accidents such as people slipping.
[0060] Continue to refer to Figures 1-4 The water in the water receiving box 2 is discharged through the outlet pipe 4 into the water storage tank 11 at the bottom of the box 1.
[0061] Specifically, one end of the outlet pipe 4 is connected to the water outlet at the bottom of the water receiving box 2. The outlet pipe 4 has a storage state and a drainage state. When the outlet pipe 4 is in the storage state, part of the outlet pipe 4 is embedded in the storage groove 13 on the inner wall of the box 1, and the height of the other end of the outlet pipe 4 is higher than the liquid level in the water receiving box 2 in the vertical direction. Because there is a liquid level difference between the outlet of the outlet pipe 4 and the liquid in the water receiving box 2, the liquid in the water receiving box 2 will not flow out from the outlet of the outlet pipe 4. When the outlet pipe 4 is in the drainage state, the outlet pipe 4 is dislodged from the storage groove 13, and the outlet pipe 4 is rotated so that the height of the other end of the outlet pipe 4 is lower than the bottom of the water receiving box 2 in the vertical direction, so that the liquid in the water receiving box 2 is discharged into the water storage tank 11 through the outlet pipe 4. In this embodiment, the outlet pipe 4 can be a flexible pipe such as a silicone tube or a rubber tube. One end of the outlet pipe 4 is sealed and connected to the water outlet at the bottom of the water receiving box 2. The outlet pipe 4 can be rotated, bent, or straightened as needed to facilitate switching between the storage state and the drainage state. The length of the outlet pipe 4 is preferably no more than the width of the box 1 to avoid the outlet pipe 4 extending out of the box 1 and causing liquid leakage.
[0062] More specifically, a guide groove 14 is recessed on the side wall of the support part 12 or the box body 1. The guide groove 14 is connected to the water storage tank 11, and the liquid in the outlet pipe 4 flows into the water storage tank 11 through the guide groove 14. In this embodiment, the guide groove 14 is set at the connection between the support part 12 and the side wall of the box body 1. When the user needs to drain the residual water in the water receiving box 2, he only needs to pull out the outlet pipe 4 and rotate the pipe body of the outlet pipe 4 so that the pipe opening of the outlet pipe 4 is facing the guide groove 14. As long as the pipe opening of the outlet pipe 4 is lower than the highest liquid level in the water receiving box 2, the water can be automatically drained. The drained water flows through the guide groove 14 at the bottom of the box body 1 and then flows into the water storage tank 11.
[0063] Preferably, the distance between the bottom of the guide channel 14 and the bottom of the water storage tank 11 gradually decreases along the direction close to the water storage tank 11. That is, the bottom of the guide channel 14 is inclined towards the water storage tank 11, which is more conducive to the flow of liquid in the guide channel 14 to the water storage tank 11.
[0064] Furthermore, along the direction close to the water storage tank 11, the bottom wall of the guide channel 14 gradually approaches the bottom of the water storage tank 11. In other words, the bottom wall of the guide channel 14 is inclined, which is beneficial for using the gravity of water to guide the flow.
[0065] Preferably, such as Figure 3 As shown, the inner wall of the groove of the storage groove 13 is provided with a limiting protrusion 131. When the outlet tube 4 is embedded in the storage groove 13, the limiting protrusion 131 abuts against the outer wall of the outlet tube 4. The limiting protrusion 131 can prevent the outlet tube 4 from coming out of the storage groove 13, thereby improving the reliability of the outlet tube 4 when it is stored.
[0066] Continue to refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 The drainage component 5 includes a drain pipe 51. A drain hole 111 is provided through the bottom of the water storage tank 11. One end of the drain pipe 51 is connected to the drain hole 111, and the other end of the drain pipe 51 is connected to an external drainage device. In other words, this drainage system can drain water from both the water receiving box 2 and the ice storage basket 3 through the water storage tank 11. It has a simple structure, can drain water without electricity, is easy to operate, easy to install and clean, and has high safety in use.
[0067] This embodiment also provides an ice maker, such as Figure 8 and Figure 9 As shown, the ice maker includes an ice maker housing 100 and the aforementioned drainage system, with the housing 1 disposed inside the ice maker housing 100. A mounting hole is provided on the side of the ice maker housing 100, and the drain connector 52 of the drainage assembly 5 is installed in the mounting hole. The drain pipe 51 is connected to an external drainage device through the drain connector 52.
[0068] It is understood that the ice maker's outer casing 100 also contains components such as an evaporator. The specific structure of the ice maker is existing technology and will not be described in detail in this embodiment.
[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
