Description

Technical Field

[0001] The present invention relates to the field of dishwashers, in particular to a drawer-type dishwasher with a fixed cover. Background Art

[0002] The water inlet of the existing drawer-type dishwasher moves back and forth with the inner tank, and the water inlet pipe connected to the water inlet also needs to move with it. As the water inlet pipe moves back and forth continuously, the water inlet pipe is pulled, which will cause the water inlet pipe and the joint to loosen, and the water inlet pipe itself to be damaged, or even fall off. The loose and damaged parts will cause leakage. At present, there is an urgent need to solve the common water leakage risks of drawer-type dishwashers. Summary of the Invention

[0003] The technical problem to be solved and the technical task to be proposed by the present invention are to improve and perfect the existing technical solutions and provide a drawer-type dishwasher with a fixed cover to prevent the water pipe from loosening. To this end, the present invention adopts the following technical solutions.

[0004] A drawer-type dishwasher with a fixed cover includes a dishwasher housing, a dishwasher inner tank assembly that can move back and forth, a cover assembly, and a water inlet assembly for water intake. The inner tank assembly is provided with a dishwashing cavity; the cover assembly can seal the opening of the dishwashing cavity, and the water inlet assembly includes a water inlet pipe communicating with the dishwashing cavity, with the dishwashing cavity opening facing upward. The cover assembly is arranged horizontally and seals the dishwashing cavity when the dishwasher inner tank assembly is pushed in. The cover assembly is fixed to the top of the inner tank of the dishwasher housing via a fixing member; a water inlet pipe hole is defined in the middle of the cover assembly, and the water inlet pipe is inserted into the water inlet pipe hole, and the water inlet pipe is fixedly connected to the cover assembly. In this technical solution, the cover is fixed, and the water inlet pipe is fixed to the cover assembly, eliminating the need for movement, preventing loosening, and solving the problem of water leakage.

[0005] As a preferred technical means: the upper inner walls of the left, right, and front sides of the dishwasher inner tank assembly are each provided with a first slot that matches the cover plate assembly. When the dishwasher inner tank assembly is pushed in, the left, right, and front sides of the cover plate assembly are embedded in the first slots. The cover plate assembly is fixed, and the dishwasher inner tank assembly is pushed backward into the dishwasher housing in a translational manner. During the process of pushing the dishwasher inner tank assembly in, the left and right sides of the cover plate assembly are gradually inserted into the first slots, and finally the front side of the cover plate assembly is inserted into the first slot on the front side of the dishwasher inner tank assembly. The dishwasher inner tank assembly and the cover plate assembly are plugged into each other. After the cover plate assembly is inserted into the first slot, although there is a gap between the cover plate assembly and the first slot, the channel formed by the gap is circuitous and can prevent water from flowing out.

[0006] As a preferred technical means: the cover assembly includes a first cover, a first seal provided on the first cover, and a second seal, both of which are elastic members; the first seal forms a "U"-shaped semi-enclosed sealing ring around the left, front, and left edges of the first cover; the second seal is located on the rear side of the first cover; the first and second seals cooperate to reduce the gap between the cover assembly and the dishwasher's inner tank assembly, thereby achieving a seal between the cover assembly and the dishwasher's inner tank assembly. The first seal cooperates with the second seal on the first cover to form an all-around seal, effectively reducing the gap between the cover assembly and the dishwasher's inner tank assembly, further preventing water from escaping, reducing steam escape, and reducing heat loss. This also helps to lower the humidity within the cabinet and reduce bacterial growth.

[0007] As a preferred technical approach, the first seal has a second slot on one side that mates with the side edge of the first cover plate. The first seal engages the left, front, and right edges of the first cover plate through the second slot and adheres to the first cover plate. A deformation hole extending through the center of the first seal is provided, extending along its length. The outer periphery of the first seal is provided with multiple longitudinal ribs. The first seal engages the edge of the first cover plate through the second slot, facilitating easy assembly and providing a secure connection. It fully protects the edges, providing a seal not only below and outside the first cover plate, but also above it, enhancing sealing effectiveness and reliability. The first seal is provided with a deformation hole to provide deformation space, store force, and provide rebound force, so that the outer side of the first seal can reliably contact the groove wall of the first slot, thereby improving the sealing performance. After the first seal is provided with the deformation hole, it has the characteristic of being easy to deform, effectively reducing the resistance to the relative movement of the cover assembly and the dishwasher inner tank assembly, and avoiding the occurrence of situations such as jamming; the ribs can reduce the contact area between the first seal and the first slot, further reducing the resistance to relative movement; multiple ribs contact the groove wall, which is equivalent to setting up multiple barriers, effectively improving the sealing performance. At the same time, the pressure when the ribs contact the groove wall is high, which can further improve the sealing effect.

[0008] As a preferred technical means: the second sealing member is provided with a front baffle, a rear baffle parallel to the front baffle, and a connecting strip connecting the front baffle and the rear baffle. The second sealing member is provided with multiple baffles to achieve sealing on the rear side.

[0009] As a preferred technical approach, the lower edge of the front baffle is lower than the rear baffle, and the rear side of the front baffle mates with the upper edge of the rear inner wall of the dishwasher's inner tank assembly; the bottom of the rear baffle can contact the rear top surface of the dishwasher's inner tank assembly. The innermost edge, the front baffle, is relatively long and is flush with the inner tank frame when closed. This prevents water from directly spraying into the joint gap, reducing the amount of water and steam that enters the rear top surface of the dishwasher's inner tank assembly. In combination with the rear baffle, this prevents any water or steam that enters the rear top surface of the dishwasher's inner tank assembly from overflowing.

[0010] As a preferred technical measure, a center retaining bar is provided below the connecting bar. The center retaining bar has a downwardly convex arc cross-section; the bottom of the center retaining bar can contact the rear top surface of the dishwasher's inner tank assembly. This downwardly convex arc provides ample room for deformation between the connecting bar and the center retaining bar, allowing the bottom of the center retaining bar to reliably contact the rear top surface of the dishwasher's inner tank assembly. The central arc edge increases the contact surface with the inner tank frame, enhancing the sealing effect and preventing water or steam from escaping from the rear top surface of the dishwasher's inner tank assembly.

[0011] As a preferred technical approach, the upper end of the front baffle extends beyond the connecting strip and extends rearward to form a first bead. The upper end of the rear baffle extends beyond the connecting strip and extends rearward to form a second bead. The first, connecting, and second bead form an inverted T-shaped groove cavity. A positioning strip is provided in the groove cavity. The cross-section of the positioning strip is convex and matches the groove cavity. The lower portion of the positioning strip is embedded in the groove cavity. The positioning strip has multiple connecting holes. Screws pass from top to bottom through the first cover plate and connect with the connecting holes of the positioning strip, clamping the first and second bead strips between the first cover plate and the positioning strip. The second seal is then hoisted onto the first cover plate via the positioning strip. The connection is reliable and assembly is convenient. The positioning strip can be made of rust-proof metal or plastic.

[0012] As a preferred technical approach, the positioning strip is provided with multiple upwardly protruding positioning posts, each of which has the connection holes. The first cover plate also has positioning holes matching the positioning posts. After the positioning posts on the positioning strip pass upward through the positioning holes in the first cover plate, screws are screwed downward into the connection holes. This facilitates connection and provides reliable positioning. The screw heads are larger than the diameter of the positioning holes, enabling the positioning strip to be hoisted.

[0013] As a preferred technical measure, the cover plate assembly further includes a second cover plate, the second cover plate being positioned below the first cover plate, the second sealing member being in contact with the rear side of the second cover plate, and the lower surface of the second cover plate being provided with a plurality of guide grooves. When the spray arm of a drawer-type dishwasher is in operation, water is forced upward to rinse dishes and other objects, impacting the cover plate and generating impact noise. The guide grooves guide the water flow, causing it to rebound in a predetermined direction, thereby improving the cleaning effect. Furthermore, the guide grooves reduce the speed of the water flow, dampening the impact noise and providing a sound-absorbing effect.

[0014] The first cover plate is a glass plate, and the second cover plate is a plastic plate; both the first cover plate and the second cover plate are provided with connecting holes for inserting screws for fixing the second cover plate to the first cover plate; the top surface of the second cover plate is provided with a groove corresponding to the guide groove, and an adhesive layer is provided between the upper surface of the second cover plate and the lower surface of the first cover plate. The corresponding grooves are provided so that the wall thickness of the second cover plate is basically the same. If the bottom is a protrusion, the top surface is a groove, and if the bottom is a guide groove, the top surface is a protrusion. This can reduce material, reduce weight, reduce deformation during use, and also reduce deformation during processing, and improve the resulting flatness. The adhesive layer can be glass glue, etc., which not only plays a bonding role, but also has a sound-absorbing effect. If the first cover plate and the second cover plate both adopt an integrated injection molding structure, then a single plastic plate will be deformed over time due to the material, sprayed with hot water, and combined with gravity. The plastic plate is combined with the glass, relying on the flatness and hardness of the glass to fix the plastic plate as a whole, ensuring that it does not deform, and avoiding changes in the angle of the guide groove that may change the direction of the water flow and affect the cleaning effect; the non-deformation feature of the glass plate can ensure the smooth pulling and sliding of the drawer, and will not cause jamming due to deformation.

[0015] As a preferred technical means: the cross-section of the guide groove is triangular, and multiple guide grooves are arranged continuously to form a guide surface. The triangular guide groove has the effect of converging water, reducing the amount of water splashing along the top surface to the edge, and concentrating the rebounding water to further improve the cleaning effect.

[0016] As a preferred technical means: the guide grooves are linear guide grooves, which are arranged side by side and continuously to form a square guide surface, which facilitates the processing of the second cover plate.

[0017] As a preferred technical means: the guide groove is an annular guide groove, and the guide groove is concentrically arranged to form a circular guide surface. The ejection surface of the rebounding water is concentrated in a circular area, which is more concentrated and is beneficial to the cleaning effect.

[0018] As a preferred technical means: the cross section of the guide groove is an isosceles triangle with a vertex angle A, where 60°≤A≤100°. This effectively controls the ejection surface of the rebounding water, preventing water overflow while improving the cleaning effect.

[0019] As a preferred technical means: the dishwasher inner tank assembly includes an inner tank and an inner tank face frame fixedly attached to the upper portion of the inner tank. The inner tank face frame is square and formed by a left frame edge, a front frame edge, a right frame edge, and a rear frame edge. The rear frame edge of the inner tank face frame is lower than the left, front, and right frame edges. The inner side walls of the left, front, and right frame edges define a first slot that matches the cover assembly. The bottom surface of the first slot is higher than the rear frame edge. When the dishwasher inner tank assembly translates backward, the left, right, and front sides of the cover assembly gradually engage with the first slot. The dishwasher inner tank assembly includes an inner tank and an inner tank face frame fixedly attached to the upper portion of the inner tank. The inner tank and the inner tank face frame are separate structures. The inner tank and the inner tank face frame can be made of different materials to facilitate processing. In particular, the inner tank face frame is made of plastic to provide a deeper first slot, which reduces processing costs, increases the wrapping surface of the cover assembly, and improves the sealing effect.

[0020] Beneficial effect: In this technical case, the cover plate is fixed, and the water inlet pipe is fixed on the cover plate assembly without moving, avoiding loosening and solving the problem of water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0038] Example 1:

[0039] like Figure 1 、 2As shown, the present invention includes a dishwasher housing 1, a dishwasher inner chamber assembly 3 that can move back and forth and is provided with a dishwashing cavity 301, a cover assembly 2 for sealing the opening of the dishwashing cavity 301, and a water inlet assembly for introducing water into the dishwasher inner chamber. The water inlet assembly includes a water inlet pipe 4 that communicates with the dishwashing cavity 301; the dishwashing cavity 301 opens upward; the cover assembly 2 is arranged horizontally, and when the dishwasher inner chamber assembly 3 is pushed in, the cover assembly 2 seals the dishwashing cavity 301; the cover assembly 2 is fixed to the top of the inner chamber of the dishwasher housing 1 via a fixing member; a water inlet pipe hole is defined in the middle of the cover assembly 2, and the water inlet pipe 4 is inserted into the water inlet pipe hole and fixedly connected to the cover assembly 2. In this technical case, the cover is fixed in a fixed manner, and the water inlet pipe 4 is fixed to the cover assembly 2, so it does not need to be moved, which prevents loosening and solves the problem of water leakage.

[0040] Example 2:

[0041] like Figure 3 、 4 As shown, the same points as those in the first embodiment are not repeated here. The difference is that, to improve the sealing effect, the upper inner walls of the left, right, and front sides of the dishwasher liner assembly 3 are each provided with a first slot 302 that matches the cover plate assembly 2. When the dishwasher liner assembly 3 is in the inserted state, the left, right, and front sides of the cover plate assembly 2 are inserted into the first slot 302. The cover plate assembly 2 is fixed, and the dishwasher liner assembly 3 is pushed backward into the dishwasher housing 1 in a translational manner. During the process of pushing the dishwasher liner assembly 3, the left and right sides of the cover plate assembly 2 are gradually inserted into the first slot 302, and finally the front side of the cover plate assembly 2 is inserted into the first slot 302 on the front side of the dishwasher liner assembly 3. The dishwasher liner assembly 3 and the cover plate assembly 2 are plugged into each other. After the cover plate assembly 2 is inserted into the first slot 302, although there is a gap between the cover plate assembly 2 and the first slot 302, the channel formed by the gap is circuitous and can prevent water from flowing out.

[0042] To further enhance sealing, the cover assembly 2 includes a first cover 5, a first seal 6, and a second seal 7 disposed on the first cover 5. Both the first and second seals 6 and 7 are elastic members. The first seal 6 forms a "U"-shaped semi-enclosed sealing ring around the left, front, and left edges of the first cover 5. The second seal 7 is located on the rear side of the first cover 5. The first and second seals 6 and 7 cooperate to reduce the gap between the cover assembly 2 and the dishwasher inner tank assembly 3, thereby achieving a seal between the cover assembly 2 and the dishwasher inner tank assembly 3. The first seal 6 and the second seal 7 on the first cover 5 form a comprehensive seal, effectively reducing the gap between the cover assembly 2 and the dishwasher inner tank assembly 3, further preventing water outflow, reducing steam escape, and reducing heat loss. This also helps to lower the humidity within the cabinet and reduce bacterial growth.

[0043] To achieve the fixation of the cover assembly 2 , in this embodiment, two parallel hanging frames 13 are used to fix the cover assembly 2 on the inner top surface of the dishwasher housing 1 .

[0044] Example 3:

[0045] like Figure 5 、 6 As shown, the similarities with the second embodiment are not repeated here. The differences are as follows: a second slot 601 is defined on one side of the first sealing member 6, which mates with the side edge of the first cover plate 5. The first sealing member 6 engages the left, front, and right edges of the first cover plate 5 through the second slot 601 and adheres to the first cover plate 5. A deformation hole 602 is defined in the middle of the first sealing member 6, extending along its length. Multiple longitudinal ribs 603 are provided on the outer periphery of the first sealing member 6. The first sealing member 6 engages the edge of the first cover plate 5 through the second slot 601, making assembly easy and secure. It fully protects the edges, providing a seal not only below and outside the first cover plate 5, but also above it, enhancing the effectiveness and reliability of the seal. The first seal 6 is provided with a deformation hole 602, which is used to provide deformation space and can store force and provide rebound force, so that the outer side of the first seal 6 can reliably contact the groove wall of the first slot 302, thereby improving the sealing performance. After the first seal 6 is provided with the deformation hole 602, it has the characteristic of being easy to deform, effectively reducing the resistance to the relative movement of the cover assembly 2 and the dishwasher inner tank assembly 3, and avoiding the occurrence of situations such as jamming; the rib 603 is provided to reduce the contact area between the first seal 6 and the first slot 302, further reducing the resistance to relative movement; multiple ribs 603 contact the groove wall, which is equivalent to setting multiple barriers, effectively improving the sealing performance. At the same time, the pressure when the rib 603 contacts the groove wall is high, which can further improve the sealing effect.

[0046] Example 4:

[0047] like Figure 7 、 8 As shown, the same parts as the second embodiment are not repeated here, except that the second sealing member 7 is provided with a front baffle 701, a rear baffle 702 parallel to the front baffle 701, and a connecting strip 703 connecting the front baffle 701 and the rear baffle 702. The second sealing member 7 is provided with multiple baffles to achieve sealing on the rear side.

[0048] The lower edge of the front baffle 701 is lower than the rear baffle 702, and the rear side of the front baffle 701 mates with the upper edge of the rear inner wall of the dishwasher liner assembly 3; the bottom of the rear baffle 702 contacts the rear top surface of the dishwasher liner assembly 3. The innermost edge, the front baffle 701, is relatively long and, when closed, is flush with the liner face frame 12. This prevents water from directly entering the joint gap, reducing the amount of water and steam that enters the rear top surface of the dishwasher liner assembly 3. Together with the rear baffle 702, this prevents any water or steam that enters the rear top surface of the dishwasher liner assembly 3 from overflowing.

[0049] To further enhance the sealing effect of the second sealing member 7, a middle retaining bar 704 is provided below the connecting bar 703. The cross-section of the middle retaining bar 704 is a downwardly convex arc. The bottom of the middle retaining bar 704 can contact the rear top surface of the dishwasher inner tank assembly 3. The downwardly convex arc shape of the middle retaining bar 704 provides ample room for deformation between the connecting bar 703 and the middle retaining bar 704, allowing the bottom of the middle retaining bar 704 to reliably contact the rear top surface of the dishwasher inner tank assembly 3. The arc-shaped edge in the middle increases the contact surface with the inner tank face frame 12, enhancing the sealing effect and preventing water or steam from escaping from the rear top surface of the dishwasher inner tank assembly 3.

[0050] To ensure the second sealing member 7 is securely fixed, the upper end of the front stopper 701 extends beyond the connecting strip 703 and extends backward to form a first bead 705. The upper end of the rear stopper 702 extends beyond the connecting strip 703 and extends backward and forward to form a second bead 706. The first bead 705, the connecting strip 703, and the second bead 706 form an inverted "T"-shaped groove cavity. A positioning strip 8 is provided in the groove cavity. The cross-section of the positioning strip 8 is a "convex" shape that matches the groove cavity. The lower portion of the positioning strip 8 is embedded in the groove cavity. The positioning strip 8 has multiple connecting holes. Screws pass through the first cover plate 5 from top to bottom and connect with the connecting holes of the positioning strip 8. The first bead 705 and the second bead 706 are clamped between the first cover plate 5 and the positioning strip 8, so that the second sealing member 7 is hoisted to the first cover plate 5 through the positioning strip 8. This provides a reliable connection and convenient assembly. The positioning strip 8 can be made of rust-proof metal, plastic, etc. This arrangement can effectively prevent the second sealing member 7 from falling off or being damaged due to loose fixation during movement.

[0051] To accurately position the second seal 7, the positioning strip 8 is equipped with multiple upwardly projecting positioning posts 801, each with a connection hole. The first cover plate 5 also has positioning holes matching the positioning posts 801. After the positioning posts 801 on the positioning strip 8 pass upward through the positioning holes in the first cover plate 5, screws are screwed downward into the connection holes. This facilitates connection and provides reliable positioning. The screw heads are larger than the diameter of the positioning holes, allowing for the positioning strip 8 to be hoisted.

[0052] Embodiment 5:

[0053] The same as the second embodiment will not be repeated here, the difference is that: Figure 9 、 10As shown in Figures 11 and 12, in order to reduce the collision sound, the cover plate assembly 2 also includes a second cover plate 9. The second cover plate 9 is located below the first cover plate 5. The second sealing member 7 is in contact with the rear side of the second cover plate 9. The lower bottom surface of the second cover plate 9 is provided with a plurality of guide grooves 901. When the spray arm of the drawer-type dishwasher is in operation, the water is urged upward to rinse the dishes and other objects while also impacting the cover plate, thus generating a collision sound. The guide grooves 901 can guide the direction of the water flow, causing the water to rebound in the set direction, which is beneficial to improving the cleaning effect. At the same time, the guide grooves 901 reduce the buffering water flow speed, reduce the collision sound of the water, and have a sound-absorbing effect.

[0054] In order to ensure flatness and reduce deformation, the first cover plate 5 is a glass plate and the second cover plate 9 is a plastic plate; both the first cover plate 5 and the second cover plate 9 are provided with connection holes for inserting screws for fixing the second cover plate 9 to the first cover plate 5. If the first cover plate 5 and the second cover plate 9 are both made of an integral injection-molded structure, a single plastic plate will deform over time due to the material and the hot water spray and the force of gravity. In this embodiment, a plastic plate is combined with glass, and the flatness and hardness of the glass are relied upon to fix the plastic plate as a whole, ensuring that it does not deform, and preventing the angle of the guide groove 901 from changing the direction of the water flow and affecting the cleaning effect. The non-deformation characteristic of the glass plate ensures that the drawer can be smoothly pulled out and drawn, and does not cause problems such as jamming due to deformation.

[0055] like Figure 13 As shown, in order to reduce material and weight, the top surface of the second cover plate 9 is provided with a groove 902 corresponding to the guide groove 901, and an adhesive layer 10 is provided between the upper surface of the second cover plate 9 and the lower surface of the first cover plate 5. The groove 902 corresponding to the guide groove 901 is provided so that the wall thickness of the second cover plate 9 is basically the same. For example, if the bottom is a protrusion, the top is groove 902, and the bottom is guide groove 901, and the top is a protrusion. This can reduce material, reduce weight, and reduce deformation during use. It also reduces deformation during processing and improves the resulting flatness. The adhesive layer 10 can be made of glass glue, etc., which not only provides bonding but also has a sound-absorbing effect.

[0056] The cross-section of the guide groove 901 can be trumpet-shaped, trapezoidal, etc. In this embodiment, the cross-section of the guide groove 901 is an isosceles triangle with a top angle A of 84°. The triangular guide groove 901 has a gathering effect on water, reducing the amount of water splashing to the edge along the top surface, and concentrating the rebounding water to improve the cleaning effect. This angle effectively controls the catapulting surface of the rebounding water, preventing water from overflowing while improving the cleaning effect.

[0057] The arrangement of the guide grooves 901 can be carried out in many ways, such as Figure 10In the embodiment, the guide groove 901 is a straight guide groove 901, and the guide grooves 901 are arranged side by side and continuously to form a square guide surface. This facilitates the processing of the second cover plate 9. Or as Figure 10 The guide groove 901 is an annular guide groove 901, and the guide groove 901 is concentrically arranged to form a circular guide surface, so that the ejection surface of the rebounding water is concentrated in a circular area, which is more concentrated and is beneficial to the cleaning effect.

[0058] Example 6:

[0059] like Figure 15 As shown, the same parts as those in Example 1 are not repeated here. The difference is that the dishwasher inner tank assembly 3 includes an inner tank 11 and an inner tank surface frame 12 fixedly connected to the upper part of the inner tank 11. The inner tank surface frame 12 is in the shape of a square frame and is surrounded by a left frame edge 121, a front frame edge 122, a right frame edge 123, and a rear frame edge 124. The rear frame edge 124 of the inner tank surface frame 12 is lower than the left frame edge 121, the front frame edge 122, and the right frame edge 123. The inner side walls of the left frame edge 121, the front frame edge 122, and the right frame edge 123 are provided with a first slot 302 that matches the cover assembly 2. The bottom surface of the first slot 302 is higher than the rear frame edge 124. When the dishwasher inner tank assembly 3 is translated backward, the left side, right side, and front side of the cover assembly 2 are gradually embedded in the first slot 302. The dishwasher inner tank assembly 3 includes an inner tank 11 and an inner tank surface frame 12 fixedly connected to the upper part of the inner tank 11. The inner tank and the inner tank surface frame 12 are split structures. The inner tank and the inner tank surface frame 12 can be made of different materials to facilitate processing, especially the opening of the first slot 302. The inner tank surface frame 12 is made of plastic. On the basis of reducing processing costs, it can have a deeper first slot 302, increase the wrapping surface of the cover assembly 2, and improve the sealing effect.

[0060] The dishwasher can be integrated into the sink or into the integrated stove.

[0061] above Figure 1-15 The drawer-type dishwasher with a fixed cover shown is a specific embodiment of the present invention, which has embodied the substantial features and progress of the present invention. Based on actual usage needs and in accordance with the teachings of the present invention, equivalent modifications in shape, structure, etc. can be made to the dishwasher, and all such modifications are within the scope of protection of this solution.
