Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a washing equipment and a base thereof. Background Art

[0002] With the improvement of people's living standards, the popularity of various types of intelligent washing equipment is becoming higher and higher, and they are widely praised by users because they can complete most routine cleaning operations on behalf of users.

[0003] Taking washing machines as an example, users have increasingly higher requirements for the capacity and washing efficiency of washing machines, which requires manufacturers to increase the capacity of washing machines to improve the efficiency of cleaning and drainage. If the capacity of the washing chamber is directly increased and the height of the washing machine is increased, the height of the washing machine will be too high, which is not conducive to user operation and the user's integrated home decoration, directly affecting the user's experience.

[0004] Therefore, existing washing equipment is gradually developing in the direction of compactness, but the compactly arranged washing equipment usually has the problem of small drainage height difference, which affects the drainage speed, and the distance between the drainage pump and the washing chamber is small when the compact setting is used, which is easy to collide during use, causing abnormal noise or damage.

[0005] In order to solve this problem, a Chinese invention patent with application number CN201320542946.1 discloses a drain valve, including a water inlet connecting pipe, a drain connecting pipe, and a valve plug cavity between the water inlet connecting pipe and the drain connecting pipe, the water inlet connecting pipe and the drain connecting pipe are connected to the valve plug cavity respectively, and also includes an overflow connecting pipe, which is at least partially located on the valve plug cavity and connected to the valve plug cavity, so that the height of the drain pipe connecting pipe is reduced, thereby reducing the overall height of the drain valve; however, the improvement of the height of the drain valve cannot increase the height difference between the water in the washing machine and the drain valve, which is not conducive to improving the drainage efficiency.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The object of the present invention is to provide a base platform for a washing device in view of the above-mentioned problems in the prior art, wherein a first fixing portion for fixing a drain valve is formed in the base platform, and the drain valve is fixed by the fixing portion, thereby increasing the height difference between the drain valve and the washing chamber of the washing device, enabling rapid drainage without a drain pump, thereby improving drainage efficiency.

[0008] Another object of the present invention is to provide a washing device with the above-mentioned base, in which the drain valve is fixed on the base by snap-fitting, which is convenient for maintenance and disassembly. The water in the washing chamber can be discharged at a faster speed, shortening the waiting time after the dehydration is completed. The drain valve is arranged on the base, which shortens the distance for water to be discharged from the washing device, which is conducive to rapid drainage.

[0009] In order to achieve the above-mentioned purpose, the present invention provides a washing equipment base, the middle part of the base is hollowed out to form an installation space for accommodating a drainage system, and the installation space is provided with:

[0010] The first fixing portion is formed by extending from the side wall of the hollowed-out portion of the base into the installation space and is used to fix the drain valve through a clamping structure arranged on the first fixing portion.

[0011] In the above scheme, the first fixed part is arranged in the installation space hollowed out on the base platform, so that the installation of the drain valve will not be affected by the base platform structure. While avoiding increasing the height of the base platform, the height difference between the drain valve and the washing chamber of the washing equipment is increased, so that water can be discharged from the washing chamber at a faster speed under the influence of the larger height difference. There is no need to set a drain pump, which reduces the number of internal components of the washing equipment and is conducive to the expansion of the volume of the washing chamber.

[0012] Furthermore, the clamping structure on the first fixing portion includes three through-set clamping slots, the clamping slots include two first clamping slots and one second clamping slot, the two first clamping slots are parallel to each other, and the second clamping slot and the two first clamping slots are not on the same straight line;

[0013] One end of the first slot away from the second slot shrinks to form a limiting shrinkage.

[0014] In the above solution, the first card slot and the second card slot are not on the same straight line, so that the three card slots can be distributed in a triangle, ensuring the installation stability of the drain valve.

[0015] Furthermore, the connection line between the two first card slots and the second card slot forms an isosceles triangle, and the second card slot is located at the vertex of the isosceles triangle.

[0016] The above arrangement further improves the installation stability of the drain valve, and the drain valve is not likely to fall off when the washing device vibrates or tilts.

[0017] Furthermore, the clamping structure further includes a supporting portion, and the supporting portion is located in a triangular area surrounded by a line connecting the first clamping slot and the second clamping slot;

[0018] The support portion is recessed downward from the top of the first fixing portion, and comprises a first support portion and a second support portion which are arranged at intervals, and the first support portion connects the two first card slots.

[0019] Preferably, the first supporting portion is arranged perpendicular to an extending direction of the first slot.

[0020] Furthermore, the first fixing portion is a horizontally arranged fixing plate, which has a certain thickness in the vertical direction and is arranged to have a downwardly open groove structure, wherein at least one side of the groove wall is a side wall of the hollowed-out portion of the base;

[0021] A reinforcing rib is provided in the groove structure, which is arranged along the extension direction of the first fixing portion, one end of which is connected to the side wall of the hollowed-out portion of the base, and the vertical height of the end connected to the side wall gradually increases in the direction close to the side wall.

[0022] Since the weight of the drain valve is borne by the first fixing part after it is installed, the bearing capacity of the first fixing part directly affects the working stability of the drain valve; since the first fixing part is a cantilever as a whole, it is easy to break at the connection where it is connected to the base when the suspended end is subjected to a large force. Therefore, the height of the reinforcing ribs in the first fixing part at the end connected to the base is gradually increased, thereby improving the bearing capacity and strength of the first fixing part and ensuring sufficient support for the drain valve; and the staggered reinforcing ribs reduce the amount of molding material used for the first fixing part, thereby reducing production costs.

[0023] It should be noted here that the reinforcing rib avoids the first clamping groove and the second clamping groove that are arranged through, so as to avoid affecting the normal fixation of the drain valve.

[0024] The second aspect of the present invention provides a washing device having the washing device base described in the above scheme, the washing device having a drain valve, the bottom of the drain valve having a protruding second fixing part, which is connected to the first fixing part of the washing device base through the second fixing part.

[0025] Specifically, the second fixing portion includes two first claws and one second claw, the two first claws are arranged parallel to each other, and the second claw is not on the same straight line as the first claw;

[0026] When the drain valve is installed in place, the first clamping claw extends into the first clamping groove, and the second clamping claw extends into the second clamping groove.

[0027] Further, the first claw includes,

[0028] A first extension section is connected to the bottom of the drain valve and extends in a vertical direction away from the drain valve;

[0029] A first clamping section is extended from the end of the extension section in a direction away from the second clamping claw;

[0030] The first extension sections and the first clamping sections of the two first clamping claws are parallel to each other;

[0031] The second claw comprises:

[0032] A second extension section is connected to the bottom of the drain valve and extends in a vertical direction away from the drain valve;

[0033] A second clamping section is extended from the end of the extension section in a direction away from the first clamping claw;

[0034] When the drain valve is installed in place, the first clamping section and the second clamping section extend into the first slot and the second slot, and are clamped with the first clamping slot and the second clamping slot respectively.

[0035] When the drain valve is successfully connected to the first fixing part, the first clamping section passes through the first clamping groove and abuts against the bottom surface of the first fixing part, and the second clamping section passes through the second clamping groove and abuts against the bottom surface of the first fixing part. Since the extension directions of the first clamping section and the second clamping section are opposite, the drain valve is fully fixed in the horizontal direction.

[0036] Furthermore, the cross-section of the first extension section along the horizontal direction is U-shaped, and the opening of the U-shaped structure is located on a side of the first claw close to the second claw;

[0037] The included angle between the first clamping section and the first extending section is a right angle, the cross-section of the first clamping section along the vertical direction is U-shaped, and the opening of the U-shaped structure faces the side of the first clamping section away from the bottom of the drain valve.

[0038] Furthermore, the cross-section of the first extension section along the horizontal direction is U-shaped, and the opening edge of the U-shaped structure is located on a side of the first claw close to the second claw;

[0039] The included angle between the first clamping section and the first extending section is a right angle, the cross-section of the first clamping section along the vertical direction is U-shaped, and the opening of the U-shaped structure faces the side of the first clamping section away from the bottom of the drain valve.

[0040] In the above scheme, the cross-sectional shape of the first extension section is U-shaped, which improves the strength of the first clamping section. Since the first clamping section is arranged at the end of the first extension section, the first extension section with a U-shaped cross-section also improves the strength of the first clamping section, thereby preventing the first clamping section from breaking or deforming after long-term use. The opening of the U-shaped structure is located on the side of the first clamping section close to the second clamping section, that is, the two ends of the U-shaped structure are arranged away from the extension direction of the first clamping section, thereby avoiding the occurrence of stress concentration and better preventing the first clamping section from breaking.

[0041] At the same time, the cross-sectional shape of the first clamping section along the vertical direction is also U-shaped, which improves the strength of the first clamping section itself. The opening of the U-shaped structure faces the side of the first clamping section away from the bottom of the drain valve, ensuring the flatness of the side where the first clamping section contacts the first fixing portion, thereby improving the fixing stability of the drain valve.

[0042] Furthermore, the second fixing portion further includes:

[0043] A first supporting rib protrudes from the bottom of the drain valve in a vertical direction and is respectively connected to the first extension sections of the two first claws;

[0044] A second supporting rib protrudes from the bottom of the drain valve in a vertical direction, is disposed between the first clamping claw and the second clamping claw, and is spaced apart from the first clamping claw and the second clamping claw;

[0045] When the drain valve is installed in place, the first supporting rib abuts against the first supporting portion, and the second supporting rib abuts against the second supporting portion.

[0046] In the above scheme, when the drain valve is installed in place, the first supporting rib and the first clamping section respectively abut against the first fixing part from both sides of the first fixing part, and the second supporting rib and the second clamping section also respectively abut against the first fixing part from both sides of the first fixing part, thereby realizing the positioning of the drain valve in the vertical direction and ensuring the tight connection between the drain valve and the first fixing part; the first supporting part and the second supporting part are both recessed, and the first supporting rib and the second supporting rib are at least partially embedded in the first supporting part and the second supporting part, thereby further improving the connection stability between the drain valve and the first fixing part; there is a gap between the second supporting rib and the first claw and the second claw, which provides a small range of movement space for the first claw and the second claw, thereby facilitating the installation and disassembly of the drain valve.

[0047] Preferably, the second supporting ribs are two strip-shaped ribs arranged in parallel, and the interval between the two strip-shaped ribs is the same as the width of the second supporting portion.

[0048] In the above solution, the second support ribs are set as two parallel strip ribs. On the one hand, the size of the second support ribs is reduced and the production cost is reduced. On the other hand, the strip ribs are easier to install than ribs of other shapes and will not be blocked during the installation of the drain valve.

[0049] The beneficial effects of the present invention are:

[0050] 1. A fixing part for fixing the drain valve is arranged at the hollow position in the middle of the base, so that the drain valve is installed on the base with a sufficient height difference between the drain valve and the washing chamber of the washing equipment. There is no need to set a drain pump in the drainage system, and water can be quickly discharged under the action of gravity, which simplifies the structure of the drainage system; the distance between the drain valve and the washing chamber is relatively far, which is conducive to the expansion of the washing chamber, and the expansion of the washing chamber will not affect the total height of the washing equipment, thereby improving the product competitiveness of the washing equipment.

[0051] 2. The first clamping groove and the second clamping groove on the first fixing part are respectively located at the three vertices of the isosceles triangle, and the installation stability of the drain valve is improved by utilizing the high stability of the triangle.

[0052] 3. The bottom of the drain valve is provided with a first claw and a second claw that cooperate with the first slot and the second slot, and is also provided with a second fixing portion that cooperates with the supporting portion on the first fixing portion. The movement of the drain valve in the vertical direction is restricted by the first claw, the second claw and the second fixing portion, thereby improving the installation stability of the drain valve.

[0053] 4. The extension directions of the first clamping section and the second clamping section are opposite, which can limit the movement of the drain valve in the horizontal direction and further improve the installation stability of the drain valve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0064] In the description of the present invention, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0065] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0066] The present invention provides a washing device, such as Figures 1 to 8 As shown, the washing device includes a drainage pump and a base 1 arranged at the bottom. The middle of the base 1 is hollowed out to form an installation space for accommodating the drainage system. The installation space is provided with:

[0067] The first fixing portion 11 is formed by extending from the side wall of the hollowed-out portion of the base 1 into the installation space, and is used to fix the drain valve 2 through a clamping structure arranged on the first fixing portion 11 .

[0068] In the above scheme, the drain valve 2 is fixed in the installation space formed by the hollowing out in the middle of the base 1. The sinking design of the drain valve 2 increases the height difference between the drain valve 2 and the washing chamber of the washing equipment, so there is no need to set a drainage pump in the drainage system. Rapid drainage can be achieved only by the height difference, which simplifies the structure of the washing equipment. The distance between the drain valve 2 and the washing chamber is increased, which is conducive to the expansion of the washing chamber without affecting the overall size of the washing equipment.

[0069] The present invention is further described in detail below with reference to specific embodiments.

[0070] It should be noted that the washing device described in the present invention can be a washing machine, a washer-dryer, a dishwasher and other types of equipment with drainage requirements. The following embodiments are illustrated by taking a washing machine as an example, which does not represent a limitation on the type of washing device.

[0071] Embodiment 1

[0072] As an embodiment of the present invention, this embodiment provides a washing device, such as Figures 1 to 3 As shown, the first fixing portion 11 of the base 1 has three through-going slots, and the drain valve 2 has three claws corresponding to the three slots. Figure 5 As shown, the drain valve 2 is fixed on the first fixing portion 11 through the cooperation of the claw and the groove.

[0073] In this embodiment, the first fixing portion 11 is a fixing plate that protrudes horizontally into the installation space, and the clamping structure on the fixing portion includes a clamping slot and a supporting portion, wherein the clamping slot includes two first clamping slots 111 and one second clamping slot 112, the two first clamping slots 111 are parallel to each other, and the second clamping slot 112 and the two first clamping slots 111 are not on the same straight line, that is, the connecting line between the three clamping slots forms a triangle, and the three clamping slots are respectively located at the three vertices of the triangle. In this way, the characteristic of the triangle having good stability is utilized, so that the drain valve 2 can be more stably connected to the first fixing portion 11.

[0074] In order to improve the fixing stability, the connection line between the three slots in this embodiment forms an isosceles triangle, wherein the two first slots 111 are located at the two base angles of the isosceles triangle, and the second slot 112 is located at the vertex angle of the isosceles triangle.

[0075] Furthermore, in order to facilitate the user to install the drain valve 2, the two first slots 111 are parallel to each other, and the claws on the drain valve 2 that cooperate with the two first slots 111 are also arranged parallel to each other. When the user actually installs it, he can use the characteristic that the two sides of the isosceles triangle are equal in length to first install the two first slots 111 in place, and then install the second slot 112 in place. At this time, the second slot 112 and the corresponding claws on the drain valve 2 can be more easily matched in place, avoiding errors during the installation process or damage to the claws due to the drain valve 2 tipping over.

[0076] In order to achieve cooperation with the first fixing part 11, a second fixing part is provided on the drain valve 2, such as Figure 6 As shown, the second fixing portion includes three claws, two of which are first claws 21, and the other is a second claw 22. The relative position relationship between the first claw 21 and the second claw 22 is the same as the first slot 111 and the second slot 112. Therefore, when the drain valve 2 is installed in place, the first claw 21 cooperates with the first slot 111, and the second claw 22 cooperates with the second slot 112 to fix the drain valve 2.

[0077] Specifically, Figure 7As shown, the first claw 21 includes a first extension section 211 and a first clamping section 212, one end of the first extension section 211 is connected to the bottom of the drain valve 2, and extends in the vertical direction away from the drain valve 2, the first clamping section 212 is connected to the other end of the first extension section 211, and extends from the connection point in the direction away from the second claw 22, forming an angle between the first extension section 211 and the first extension section 211; the second claw 22 includes a second extension section and a second clamping section 222, the second extension section is parallel to the first extension section 211, and the end of the first extension section 211 and the end of the second extension section are located in the same horizontal plane, the second clamping section 222 is connected to the extension end of the second extension section, and extends from the connection point in the direction away from the first claw 21; since the first claw 21 and the second claw 22 extend in different directions respectively, when the drain valve 2 is installed in place, the first claw 21 and the second claw 22 limit the drain valve 2 from different directions respectively.

[0078] It should be noted here that in order to fully fix the drain valve 2, when the drain valve 2 is installed in place, the first clamping section 212 and the second clamping section 222 pass through the first clamping groove 111 and the second clamping groove 112 and abut against the bottom surface of the first fixed portion 11, the first extension section 211 abuts against the side of the first clamping groove 111 away from the second clamping groove 112, and the second extension section abuts against the side of the second clamping groove 112 away from the first clamping groove 111, thereby achieving full fixation of the drain valve 2.

[0079] To facilitate installation by the user, the two first claws 21 are arranged parallel to each other, or the first engaging sections 212 on the two first claws 21 are arranged parallel to each other, so that the user can insert the two first claws 21 into the first slot 111 at the same time, thereby improving installation convenience.

[0080] Furthermore, the support portion is disposed within the isosceles triangle formed by the connecting line between the slots, and the drain valve 2 is supported by the support portion, so that after the drain valve 2 is installed in place, it can maintain a stable connection in the vertical direction without moving in the vertical direction.

[0081] Among them, the supporting part includes a first supporting part 113 and a second supporting part 114, and the first supporting part 113 and the second supporting part 114 are both located at the top of the first fixing part 11, and can support the drain valve 2 when the drain valve 2 is installed in place, and then realize the vertical fixation of the drain valve 2 under the cooperation of the supporting part and the first claw 21 and the second claw 22, so as to avoid the movement of the drain valve 2 after being installed in place and affecting the normal drainage.

[0082] The drain valve 2 is also provided with a first supporting rib 23 and a second supporting rib 24, both of which protrude from the bottom of the drain valve 2 in the vertical direction, wherein the first supporting rib 23 is located between the two first claws 21, and the second supporting rib 24 is arranged close to the second claw 22. When the drain valve 2 is installed in place, the first supporting rib 23 and the second supporting rib 24 cooperate with the first supporting portion 113 and the second supporting portion 114 respectively, thereby further strengthening the fixing effect of the drain valve 2.

[0083] The first support portion 113 and the second support portion 114 can be matched with each other by abutting, snapping, or other conventional methods in the art.

[0084] like Figure 7 and Figure 8 As shown, the drain valve 2 installed on the first fixed part 11 has a water inlet and a water outlet. Since the drain valve 2 is not arranged close to the edge of the base 1, the water outlet still needs to be connected to the drain port 12 on the base 1 through the drain pipe 5; the water inlet of the drain valve 2 is connected to the washing chamber of the washing equipment through a pipeline. Since the drain valve 2 sinks into the base 1, the height difference between the drain valve 2 and the washing chamber is further increased, so that the drainage system does not need to be equipped with a drainage pump, and rapid drainage can be achieved only by gravity, which simplifies the structure of the drainage system; the distance between the outlet of the drain valve 2 and the drain port 12 on the base 1 is short, and the drain valve 2 is not easy to be greatly deformed under the influence of gravity, which is conducive to the rapid discharge of water and avoids the occurrence of water accumulation in the pipeline.

[0085] Furthermore, a filter 3 is provided upstream of the water inlet of the drain valve 2. A removable filter element is provided in the filter 3. The disassembly port of the filter element is arranged toward the front side of the washing device. A disassembly port is provided on the front panel of the washing device to facilitate the user to directly clean or replace the filter element of the filter 3; the inlet 4 of the filter is directly connected to the washing chamber of the washing device.

[0086] Embodiment 2

[0087] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the first embodiment.

[0088] In this embodiment, if Figure 7As shown, the first support portion 113 and the second support portion 114 are formed by being recessed downward from the top of the first support portion 113, wherein the two ends of the first support portion 113 are respectively connected to the two first slots 111, and the second support portion 114 is close to the second slot 112 and has a gap with the second slot 112; the lengths of the first support rib 23 and the second support rib 24 arranged on the drain valve 2 are also correspondingly extended, so that when the drain valve 2 is installed in place, the ends of the first support rib 23 and the second support rib 24 can extend into the first support portion 113 and the second support portion 114 and maintain abutment with the first support portion 113 and the second support portion 114; since the first support rib 23 and the second support rib 24 are respectively embedded in the first support portion 113 and the second support portion 114, the installation of the drain valve 2 can be further positioned.

[0089] Furthermore, both ends of the first supporting rib 23 are respectively connected to the two first claws 21, which further improves the strength of the first claws 21 while positioning the installation position of the drain valve 2 in the vertical direction; in order to fully support the two first claws 21, the first supporting rib 23 is parallel to the connecting line of the two first claws 21, which can provide greater supporting force and effectively prevent the first claws 21 from deformation.

[0090] Furthermore, in order to ensure a better positioning effect, the angle between the first clamping section 212 and the first extension section 211 is a right angle, and the angle between the second clamping section 222 and the second extension section is also a right angle; the cross-sectional shape of the first extension section 211 is U-shaped, which improves the strength of the first clamping section 21; since the first clamping section 212 is arranged at the end of the first extension section 211, the first extension section 211 with a U-shaped cross-section also improves the strength of the first clamping section 212, thereby preventing the first clamping section 212 from breaking or deforming after long-term use; the opening of the U-shaped structure is located on the side of the first clamping section 21 close to the second clamping section 22, that is, the two ends of the U-shaped structure are arranged away from the extension direction of the first clamping section 212, thereby avoiding the occurrence of stress concentration and better preventing the first clamping section 212 from breaking.

[0091] Further, such as Figure 2 and Figure 3 As shown, a limiting constriction is formed at one end of the first slot 111 away from the second slot 112, and the size of the limiting constriction matches the width of the first extension section 211. On the one hand, the first claw 21 is guided by the limiting constriction, so that the first claw 21 can be installed in place more easily. On the other hand, the first claw 21 is embedded in the limiting constriction when installed in place, and the lateral displacement of the first claw 21 is limited by the limiting constriction, which further improves the stability of the drain valve 2 when it is installed in place.

[0092] Furthermore, the first engaging sections 212 on the two first claws 21 are parallel to each other and extend in a direction away from the second claw 22. The second claw 22 is arranged perpendicular to the extension direction of the first engaging section 212 and has a certain extension in its length direction. When the second claw 22 and the second slot 112 are engaged in place, the second extension section on the second claw 22 and the notch edge of the second slot 112 have a larger fitting area, which is beneficial to improving the installation stability of the drain valve 2.

[0093] Furthermore, the second supporting rib 24 is configured as two parallel strip ribs, and the interval between the two strip ribs is the same as the width of the second supporting portion 114, that is, when the drain valve 2 is installed in place, the two strip ribs are embedded in the second supporting portion 114, and respectively abut against the two opposite sides of the second installation portion, thereby further improving the accuracy and stability of the positioning of the drain valve 2.

[0094] Embodiment 3

[0095] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the second embodiment.

[0096] In this embodiment, if Figure 4 As shown, the first fixing portion 11 is a horizontally arranged fixing plate, which has a certain thickness in the vertical direction and is arranged to have a downwardly opening groove structure, wherein at least one side of the groove wall is the side wall of the hollow part of the base 1, and reinforcing ribs 115 are arranged in the groove structure. The reinforcing ribs 115 are arranged along the extension direction of the first fixing portion 11, thereby improving the overall strength of the first fixing portion 11, avoiding the first fixing portion 11 from breaking at the position connected to the side wall of the hollow part of the base 1, and improving the supporting effect on the drain valve 2.

[0097] Furthermore, the height in the vertical direction of one end of the reinforcing rib 115 connected to the side wall of the hollow part of the base 1 gradually increases in the direction close to the side wall, that is, the end of the reinforcing rib 115 connected to the side wall of the hollow part of the base 1 gradually protrudes from the bottom of the first fixing part 11 in the direction close to the side wall. Since the weight of the drain valve 2 is borne by the first fixing part 11 after it is installed, the bearing capacity of the first fixing part 11 directly affects the working stability of the drain valve 2; since the first fixing part 11 is a cantilever as a whole, its suspended end is prone to breakage at the connection with the base 1 when the force is large. For this reason, the height of the reinforcing rib 115 in the first fixing part 11 at one end connected to the base 1 gradually increases, thereby improving the bearing capacity and strength of the first fixing part 11 and ensuring sufficient support for the drain valve 2; and the staggered reinforcing ribs 115 reduce the amount of molding material of the first fixing part 11 and reduce the production cost.

[0098] In order to ensure smooth installation of the drain valve 2 , the reinforcing rib 115 avoids the positions of the first clamping groove 111 and the second clamping groove 112 .

[0099] Furthermore, the reinforcing ribs 115 are arranged in a staggered manner in the first fixing portion 11 , which improves the strength of the first fixing portion 11 while preventing the first fixing portion 11 from breaking, and effectively prevents the first fixing portion 11 from being deformed due to long-term pressure from the drain valve 2 .

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
