[0034] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element, or there can be one or more intermediate elements present between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements present between them. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.
[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0036] Please see Figures 1 to 3 The filter 100 provided in this embodiment includes a body 10, which has a first edge 101 that abuts against the plane 2001 where the target drain outlet 200s is located. The body 10 has a plurality of filter holes 10s that communicate with the target drain outlet 200s. The first edge 101 is recessed in a direction away from the water tank 200 to form a plurality of first through holes 10a that communicate with the target drain outlet 200s. With this filter 100 design, because the first through holes 10a are provided at the first edge 101 where the filter 100 abuts against the plane 2001 where the target drain outlet 200s is located, and these first through holes 10a are connected to the target drain outlet 200s, water can be discharged through both the filter holes 10s and the first through holes 10a during drainage. This design makes the first through hole 10a at the first edge 101 where the filter screen 100 contacts the water tank 200 a drainage channel, thereby effectively improving drainage efficiency.
[0037] The first through hole 10a serves as a drainage channel, and its shape can vary. In some embodiments, the first through hole 10a is semi-circular. Compared to cases where the arc of the first through hole 10a is greater than 180 degrees, the filter screen 100 with the semi-circular first through hole 10a is easier to demold when the filter screen 100 is formed by the mold.
[0038] In some embodiments, please refer to Figure 4The filter screen 100 also includes an opening retaining rib 20, which is disposed on the surface of the body 10 relative to the plane 2001 at the location of the target drain outlet 200s, or the opening retaining rib (not shown) is disposed on two opposing surfaces of the body 10. The opening retaining rib 20 is used for installing or removing the filter screen 100, improving the convenience of assembling and removing the filter screen 100.
[0039] In some embodiments, please refer to Figure 4 and Figure 5 The main body 10 includes a first wall 11 and a second wall 12 disposed opposite to each other, and a top wall 13 and a front side wall 14 connected between the first wall 11 and the second wall 12 to form a surrounding cover disposed at the target drain outlet 200s. First through holes 10a are provided on the non-connecting edges of the front side wall 14, the first wall 11, and the second wall 12, and uniformly distributed filter holes 10s are provided on the first wall 11, the second wall 12, and the front side wall 14. With this arrangement, during drainage, water can pass through the first through holes 10a on the non-connecting edges of the second wall 12, the first wall 11, and the front side wall 14, and also through the filter holes 10s on the first wall 11, the second wall 12, and the front side wall 14. That is, water can enter the main body 10 of the filter screen 100 from different directions, resulting in high drainage efficiency of the filter screen 100.
[0040] In some embodiments, please refer to the following: Figure 3 , Figure 4 and Figure 5 Both the first wall 11 and the second wall 12 are roughly L-shaped, meaning that the two non-connecting sides of the first wall 11 and the second wall 12 are set at 90°. Generally, the water tank 200 is rectangular, and the target drain outlet 200s is located on the bottom wall of the water tank 200. Therefore, when the filter screen 100 is installed above the target drain outlet 200s, one non-connecting side of the first wall 11 and the second wall 12 abuts against the bottom wall of the water tank 200, and the other non-connecting side abuts against the side wall of the water tank 200.
[0041] In some embodiments, the top wall 13 includes a support portion 131 and a recessed portion 132. The recessed portion 132 is recessed into the body 10 relative to the support portion 131. The recessed portion 132 includes a third wall 1321 disposed parallel to the front sidewall 14. Filter holes 10s are provided on the third wall 1321 and the support portion 131. By providing filter holes 10s on the support portion 131 and the third wall 1321 of the recessed portion 132 of the top wall 13, the number of filter holes 10s on the body 10 of the filter screen 100 is further increased, thereby increasing the amount of water entering the filter screen 100 in the same time period and improving the drainage efficiency of the filter screen 100.
[0042] In some embodiments, please refer to Figure 6An angle α exists between the plane of the supporting part 131 and the plane 2001 where the target drain outlet 200s is located, and the degree of the angle α is less than 90°. The distance H1 between the end of the supporting part 131 away from the front sidewall 14 and the plane 2001 where the target drain outlet 200s is located is greater than the distance H2 between the end of the supporting part 131 near the front sidewall 14 and the plane 2001 where the target drain outlet 200s is located. With this arrangement, the supporting part 131 is inclined relative to the plane 2001 where the target drain outlet 200s is located, which facilitates water entering the target drain outlet 200s from the supporting part 131.
[0043] In some embodiments, mounting posts 1101 are provided on the two opposite walls of the body 10 of the filter screen 100. The mounting posts 1101 are assembled with mounting sleeves 201 provided on the plane 2001 at the location of the target drain outlet 200s, providing a specific implementation of assembling the filter screen 100 into the water tank 200. Figure 3 Combination Figure 5 As shown, mounting posts 1101 with opposite positions are provided on the first wall 11 and the second wall 12, and mounting sleeves 201 protruding from the surface are provided on the bottom wall of the water tank 200.
[0044] It is understandable that a mounting sleeve 201 can be provided on the body 10 of the filter screen 100, and a mounting post 1101 can be provided on the bottom wall of the water tank 200, so as to realize the detachable connection between the filter screen 100 and the water tank 200.
[0045] In addition, there are various ways to connect the filter screen 100 to the water tank 200, such as a snap-fit connection or a threaded connection between the mounting post 1101 and the mounting sleeve 201. The connection method between the two is not limited here, and the connection method can be selected according to the actual situation.
[0046] In some embodiments, baffles 1102 are provided on the opposite two walls of the body 10, the baffles 1102 are arranged around the mounting post 1101, and the baffles 1102 are sleeved on the mounting sleeve 201. With this arrangement, when the mounting post 1101 of the filter screen 100 is assembled into the mounting sleeve 201 of the water tank 200, the baffles 1102 of the filter screen 100 are sleeved outside the mounting sleeve 201, providing a certain limiting effect, thereby improving the reliability of the filter screen 100 in the water tank 200. Furthermore, when the filter screen 100 is used in corrosive liquids, the baffles 1102 further strengthen the protection of the mounting structure, reduce the loosening of the filter screen 100 due to liquid erosion, and increase the service life of the filter screen 100. Figure 4As shown, the baffles 1102 are respectively provided on the first wall 11 and the second wall 12, and protrude from the two wall surfaces. In addition, the height of the baffles 1102 is preferably slightly lower than the height of the first wall 11 and the second wall 12 at the same position, so that a handhold can be formed on the first wall 11 and the second wall 12, so that the user can grasp the filter 100 from different directions except for the position of the opening surrounding rib 20.
[0047] According to one aspect of the embodiments of this application, please refer to the following: Figures 1 to 3 A household appliance 1000 is provided, including a sink 200, a water pump 300, and a filter 100. The sink 200 has a target drain outlet 200s, the water pump 300 is connected to the target drain outlet 200s, and the body 10 of the filter 100 covers the target drain outlet 200s. The first edge 101 of the filter 100 abuts against the sink 200 and is arranged around the target drain outlet 200s. For the specific structure and function of the filter 100, please refer to the foregoing description; it will not be repeated here. When the household appliance 1000 drains water, the filter 100 filters out some impurities, reducing the risk of impurities entering the water pump 300 and causing blockage.
[0048] In some embodiments, the water tank 200 is provided with baffles 203, which surround the target drain outlet 200s, and the first edge 101 surrounds the baffles 203. With the baffles 203 in place, some impurities passing through the first through hole 10a of the filter screen 100 are blocked by the baffles 203, reducing the risk of blockage of the water pump 300.
[0049] In some embodiments, the height of the baffle 203 is preferably between the radius and diameter of the semi-circular first through hole 10a. By limiting the height of the baffle 203, some impurities can be blocked from entering the water pump 300 through the target drain outlet 200s, and the baffle 203 will not affect the efficiency of water discharge through the first through hole 10a too much.
[0050] The height of the baffle 203 refers to the size of the baffle 203 along the direction in which it protrudes from the water tank 200.
[0051] It is understandable that the aforementioned household appliance 1000 refers to household appliances with a water tank 200 that require filtration, such as ice makers, instant hot water dispensers, humidifiers, etc.
[0052] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
