Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of dishwashers, and particularly relates to a filter of a dishwasher and a dishwasher with the filter. BACKGROUND

[0002] The dishwasher is a device for automatically cleaning dishes, chopsticks, plates, dishes, knives and forks, etc. It reduces the labor intensity of cooks in restaurants, hotels and canteens, improves work efficiency, and improves cleanliness. Now, small dishwashers are gradually entering ordinary families, but food residues are stuck on the dishes, so a filter structure needs to be provided on the dishwasher.

[0003] In the prior art, a commonly used dishwasher generally comprises an inner tank, a water tank is generally arranged at the bottom of the inner tank, and a filter assembly is arranged in the water tank. The filter assembly comprises a filter screen and a residue collection net installed on the filter screen, and the residue collection net extends into the water tank. The residue collection net is locked and fixed in the water tank, and the filter screen is fixed above the water tank through the pressing action of the residue collection net. When the filter screen of such a dishwasher needs to be cleaned, the residue collection net needs to be removed first, and then the filter screen needs to be removed for cleaning. Therefore, the filter assembly is inconvenient to clean and has poor practicality.

[0004] At present, a locking structure cooperating with the water tank is arranged on the outer side of the frame of the residue collection net. A certain gap is required between the inner wall of the water tank and the residue collection net for the passage of water flow. Therefore, the fixing and positioning accuracy of the residue collection net is not high, and the stability of the fixing is not good. This may cause the edge of the filter screen to be raised, and food residues to flow directly into the waterway from the gap. Or the gap between the residue collection net and the filter screen enters the waterway. The locking structure arranged on the outer side of the frame of the residue collection net has low strength, and is prone to damage during frequent disassembly. In addition, the structural strength of the residue collection net itself is weak, and during the working process, the cleaning water mixed with food residues flows into the upper opening of the residue collection net to achieve filtering. However, the upper opening of the residue collection net allows the collected food residues to be seen, which is not conducive to the aesthetic appearance. Under the impact of strong water flow, the collected food residues may be washed out, reducing the cleaning efficiency. SUMMARY

[0076] Referring to Figures 1-4 As shown in the figure, the filter 7 comprises an upper cover 73, the upper cover 73 is buckled on the cover frame 715, the cover frame 715 has a downward and inward inclined inner end face, and the edge of the upper cover 73 contacts the inner end face of the cover frame 715. By arranging the upper cover 73, the structural arrangement of the cover frame 715 is facilitated, and the observation of the matching relationship during installation of the filter 7 is facilitated, and the assembly speed is improved. And by arranging the edge of the upper cover 73 to contact the inner end face of the cover frame 715, the tightness of the buckling of the upper cover 73 is facilitated. A plurality of support ribs 717 are arranged between the cover frame 715 and the mounting edge 713, and the water flow inlet 716 is arranged between the adjacent two support ribs 717. A plurality of mounting handles 718 extending outward at intervals are arranged on the cover frame 715; by applying torque to the mounting handle 718, the rotation of the filter support frame 71 is realized, and the torque is facilitated, so that the operation of mounting the filter 7 to the inner container 30 is simple and convenient.

[0077] Referring to Figure 6 and Figure 10As shown, the upper cover 73 is provided with a fourth clamping jaw 731 extending downward, which is clamped on the support body 710. By arranging the fourth clamping jaw 731 extending downward, the upper cover 73 is clamped and fixed on the support body 710, which is beneficial to the stability after fixing and the simple clamping operation, and is beneficial to improving the efficiency. The support body 710 is in a basin shape, that is, has a flat support bottom 7101 and a peripheral wall 7102 extending outward and upward along the edge of the support bottom 7101, and the assembly along 713 is connected with the upper end of the peripheral wall 7102. By arranging the basin-shaped support body 710, the water flow entering the support body 710 through the water inlet 716 flows to the support bottom 7101, which is beneficial to increasing the water flow speed and avoiding water residue in the support body 710. The water inlet 7103 is arranged on the support bottom 7101, and the fourth clamping jaw 731 is clamped and fixed on the edge of the water inlet 7103. In this way, a clamping hole structure matched with the fourth clamping jaw 731 does not need to be specially arranged, and the fourth clamping jaw 731 is directly clamped on the edge of the water inlet 7103. The support bottom 7101 is circular, and the water inlet 7103 is an arc surface concentric with the support bottom 7101. The central angle corresponding to the water inlet 7103 is less than 90°.

[0078] Referring to Figure 4 and Figure 10 As shown, a limiting structure is arranged between the upper cover 73 and the support body 71 for clamping the upper cover 73, which ensures the stability and firmness of the upper cover 73 after fixing. The limiting structure is a plurality of second limiting plates 719 arranged vertically upward on the support bottom 7101 of the support body 71 and a plurality of second limiting grooves 732 arranged vertically downward on the upper cover 73, and the second limiting plates 719 are located in the second limiting grooves 732. It is preferred that any two second limiting plates 719 are perpendicular to each other, or parallel to each other, or coplanar. Specifically, the plurality of second limiting plates 719 form a cross shape or a T shape, and the intersection line of the plurality of second limiting plates 719 is collinear with the axis of the filter support frame 71. Through the cooperation of the second limiting plates 719 and the second limiting grooves 732, the positional relationship between the upper cover 73 and the filter support frame 71 is limited, the fourth clamping jaw 731 is clamped and fixed on the edge of the water inlet 7103, and the stability of the upper cover 73 after fixing is high.

[0079] The filter 7 has, from top to bottom, an upper cover 73, a filter support frame 71, and a cup-shaped filter screen 72 in sequence, the water flow mixed with food residues passes through the filter support frame 71 into the cup-shaped filter screen 72 to realize the filtration of the food residues, and then the water flow enters the water flow channel. The filter 7 further has the cup-shaped filter screen 72 arranged on the filter support frame 71; the inner tank 30 of the dishwasher is provided with an inner recessed water groove 305, and a locking structure is arranged between the bottom surface of the water groove 305 and the filter support frame 71. By arranging the locking structure between the filter support frame 71 and the bottom surface of the water groove 305, the locking structure has a larger arrangement space, a relatively firm structure can be arranged, the strength of the locking structure is increased, the firmness and stability of the filter 7 after installation are improved; in addition, the locking structure is arranged between the bottom surface of the water groove 305 and the filter support frame 71, the locking structure is fixed in the up-down direction, the position accuracy of the filter 7 after installation can be ensured, and the problem that food residues enter the water channel due to a large assembly gap is avoided.

[0080] Referring to Figures 11-20 It is described that the dishwasher has the above filter, the dishwasher is a drawer dishwasher, and the inner tank 30 is arranged in the drawer 20; referring to Figure 13 The filter 7 further has the upper cover 73 buckled on the filter support frame 71, the filter 7 has, from top to bottom, the upper cover 73, the filter support frame 71, and the cup-shaped filter screen 72 in sequence, the water flow mixed with food residues passes through the filter support frame 71 into the cup-shaped filter screen 72 to realize the filtration of the food residues, and then the water flow enters the water flow channel. The dishwasher further includes a fan-shaped filter screen 8 arranged in the inner tank 30, referring to Figure 5 An installation opening 81 is arranged on the fan-shaped filter screen 8, and the lower part of the filter 7 is fixed on the inner tank 30 through the installation opening 81. The installation opening 81 is provided with an inwardly inclined lower recess 811 and an installation edge 812 extending inwardly along the lower end of the lower recess 811, the filter 7 is pressed against the installation edge 812 to ensure the sealing between the filter 7 and the filter 8. The filter 7 needs to give a certain pressing force to the installation edge 812 to ensure the sealing between the filter 7 and the installation edge 812, but also needs to avoid that the pressing force is too large to cause the installation edge 812 to have a large deformation downwardly, so that the edge of the fan-shaped filter screen 8 is raised; in the embodiment, the locking structure is fixed in the up-down direction, which is conducive to ensuring the assembly accuracy between the filter 7 and the installation edge 812, ensuring that the filter 7 gives the installation opening 81 with a suitable pressing force, being conducive to ensuring the cleaning efficiency and avoiding the blockage of the water channel and the like.

[0081] Referring to Figure 13As shown, the inner recessed sink 305 is arranged on the inner container 30 of the dishwasher, and the locking structure is arranged between the bottom surface of the sink 305 and the filter support frame 71. By arranging the locking structure between the filter support frame 71 and the bottom surface of the sink 305, the locking structure has a larger setting space, a relatively firm structure can be arranged, the strength of the locking structure is increased, the firmness and stability of the filter 7 after installation are improved; in addition, the locking structure is arranged between the bottom surface of the sink 305 and the filter support frame 71, the locking structure is fixed in the upward-downward direction, the position accuracy of the filter 7 after installation can be ensured, and the food residues entering the waterway due to a large assembly gap can be avoided.

[0082] As shown in Figure 12 and Figure 15 As shown, the filter device of the dishwasher includes the filter 7 and the fan-shaped filter screen 8 arranged in the inner container 30, the mounting port 81 is arranged on the fan-shaped filter screen 8, and the lower part of the filter 7 is fixed on the inner container 30 through the mounting port 81. The downwardly inclined lower recess 811 is arranged on the mounting port 81, and the inwardly extending mounting edge 812 is arranged along the lower end of the lower recess 811, the filter 7 is pressed against the mounting edge 812, and the sealing between the filter 7 and the filter 8 is ensured. The filter 7 should give a certain pressing force to the mounting edge 812 to ensure the sealing between the filter 7 and the mounting edge 812, but also to avoid that the pressing force is too large to cause the mounting edge 812 to have a large downward deformation, which causes the edge of the fan-shaped filter screen 8 to be raised; in the embodiment, the locking structure is fixed in the upward-downward direction, which is conducive to ensuring the assembly accuracy between the filter 7 and the mounting edge 812, ensuring that the filter 7 gives the mounting port 81 a suitable pressing force, which is conducive to ensuring the cleaning efficiency and avoiding the blockage of the waterway and other problems.

[0083] As shown in Figures 4-7 and Figure 13As shown, the locking structure comprises a plurality of first locking members 3051 protruding upwardly on the bottom surface of the water tank 305, and a plurality of second locking members 711 extending downwardly on the filter support frame 71, the second locking members 711 being arranged at the lower end of the support bottom 7101, and the first locking members 3051 and the second locking members 711 being rotationally locked. Since the cup-shaped filter screen 72 is located at the lower portion of the filter support frame 71, a through hole 721 for the first locking members 3051 to extend into is formed on the bottom surface of the cup-shaped filter screen 72, and the through hole 721 is matched with the first locking members 3051. By controlling the size of the first locking members 3051 and the second locking members 711 in the up-down direction, the assembly accuracy between the filter 7 and the mounting edge 812 is ensured. By setting the first locking members 3051 and the second locking members 711 to be rotationally locked, the assembly efficiency is improved, and the first locking members 3051 and the second locking members 711 hardly deform during the clamping process, that is, the first locking members 3051 and the second locking members 711 do not need to deform by themselves to realize clamping and fixing during the rotation locking process. In this way, the assembly accuracy between the filter 7 and the mounting edge 812 is greatly improved, and the first locking members 3051 and the second locking members 711 can be set to have greater structural strength to ensure the firmness after assembly. When the filter 7 is installed to the inner container 30, the filter 7 is placed into the water tank 305 from top to bottom through the mounting port 81; the plurality of first locking members 3051 respectively extend into the cup-shaped filter screen 72 through the corresponding through holes 721, and then are rotationally locked.

[0084] Referring to Figure 14 As shown, the first locking member 3051 has a first supporting portion 30511 extending upwardly along the bottom surface of the water tank 305, a first claw portion 30512 extending horizontally along the top end of the first supporting portion 30511, and a reinforcing portion 30513 arranged outside the first supporting portion 30511 and the first claw portion 30512, the lower end of the reinforcing portion 30513 being connected with the bottom surface of the water tank 305, and the reinforcing portion 30513 being an arc surface. By setting the reinforcing portion 30513, the structural strength of the first locking member 3051 is increased, and the guiding and limiting effect of the second locking member 711 during rotation locking is facilitated. There are three first locking members 3051 uniformly distributed on the bottom surface of the water tank 305, which is conducive to improving the stability and firmness of the locking of the first locking members 3051 and the second locking members 711.

[0085] Referring to Figure 4As shown, the second locking member 711 has a second support portion 7111 extending downward, and a second claw portion 7112 extending outward along the outer side of the second support portion 7111; the lower end surface of the first claw portion 30512 and the upper end surface of the second claw portion 7112 are matched and engaged, and the second support portion 7111 is an arc surface. The second claw portion 7112 is arranged on the outer side of the second support portion 7111, so that the arc surface length of the second support portion 7111 is larger, which is beneficial to increase the structural strength and increase the stress performance. In order to realize the rotation locking, the second claw portion 7112 is arranged to be inclined, and a second stop portion 7113 extending upward is arranged on the inclined rising end of the second claw portion 7112, which is used to limit the first locking member 3051 to be locked in place. The first support portion 30511 is used to limit the locking of the second locking member 711 in place. The lower end surface of the first claw portion 30512 is an inclined surface matched with the inclined direction of the second claw portion 7112,

[0086] In order to increase the structural strength at the via hole 721 and increase the cooperation between the first locking member 3051 and the via hole 721, an extension portion 7211 extending upward is arranged at the via hole 721, and an avoidance groove 7212 through which the second claw portion 7112 passes is arranged on the extension portion 7211. By arranging the extension portion 7211, the cooperation area between the via hole 721 and the first locking member 3051 is increased, which is beneficial to improve the stability after assembly; and the avoidance groove 7212 is arranged, so that the first claw portion 30512 of the first locking member 3051 can pass through and be screwed on the second locking member 711.

[0087] Referring to Figure 20As shown, the first locking member 3051 matches the through hole 721, when the first locking member 3051 and the second locking member 711 are locked in rotation, the cup-shaped filter screen 72 should be static relative to the first locking member 3051, that is, the filter support frame 71 rotates, so that the first locking member 3051 and the second locking member 711 are locked in rotation, and the cup-shaped filter screen 72 has a relative rotation relationship with the filter support frame 71. After the filter 7 is placed in the water tank 305, the first locking member 3051 extends into the cup-shaped filter screen 72 through the through hole 721; when the filter support frame 71 is rotated and installed, the first locking member 3051 provides support force to the through hole 721, so that the cup-shaped filter screen 72 and the filter support frame 71 are relatively rotated. In order to further increase the positioning of the cup-shaped filter screen 72, avoid the force of relative rotation between the first locking member 3051 and the through hole 721 causing structural deformation, and causing the assembly precision between the filter 7 and the installation side 812 to decrease. Preferably, the first locking member 3051 and the through hole 721 are provided with positioning, a limiting block 306 for stopping the rotation of the cup-shaped filter screen 72 is arranged in the water tank 305, a limiting portion 722 matched with the limiting block 306 is arranged on the cup-shaped filter screen 72, and the limiting block 306 extends into the limiting portion 722; by arranging the limiting block 306 and the limiting portion 722, the rotation firmness between the cup-shaped filter screen 72 and the water tank 305 is increased.

[0088] Referring to Figure 9As shown, the limiting portion 722 has a first limiting opening 7221 formed in the bottom surface of the cup-shaped filter screen 72, and a second limiting opening 7222 formed in the side surface of the cup-shaped filter screen 72, the first limiting opening 7221 and the second limiting opening 7222 are communicated, the width of the first limiting opening 7221 is greater than the width of the second limiting opening 7222; which is conducive to the positioning of the cup-shaped filter screen 72 in the circumferential direction, and is conducive to the positioning of the cup-shaped filter screen 72 in the radial direction, and increases the firmness of the cup-shaped filter screen 72. The limiting block 306 has a limiting body 3061 matched with the second limiting opening 7222, and an extended flange 3062 provided on the end of the limiting body 3061 close to the axis of the filter 7, wherein the limiting body 3061 is located in the second limiting opening 7222, the flange 3062 extends into the cup-shaped filter screen 72 from the first limiting opening 7221, and the flange 3062 is stopped on the inner side of the second limiting opening 7222. The cup-shaped filter screen 72 moves from top to bottom, so that the limiting portion 722 is buckled on the limiting block 306; which limits the movement of the cup-shaped filter screen 72 in the circumferential direction and the radial direction, or in other words, limits the forward rotation, reverse rotation and movement in the radial direction of the cup-shaped filter screen 72; which is conducive to increasing the firmness of the cup-shaped filter screen 72. A baffle 725 extending radially upward is arranged on the bottom surface of the cup-shaped filter screen 72, the baffle 725 is located on the inner side of the first limiting opening 7221, and is used to stop the positioning of the limiting block 306; when the limiting block 306 and the limiting portion 722 are installed in cooperation, the baffle 725 plays a limiting and guiding role, and after installation, it is conducive to limiting the movement trend of the limiting block 306 and the limiting portion 722 in the direction of approaching each other.

[0089] When the filter 7 is installed on the inner container 30 of the dishwasher, the cup-shaped filter screen 72 is stationary relative to the inner container 30, and the filter support frame 71 is rotated and fixed with the inner container 30. By rotating and fixing the cup-shaped filter screen 72 to the filter support frame 71, it is conducive to improving the assembly speed of the filter 7 during assembly, and by rotating and fixing, it is conducive to improving the stability after fixing; by rotating and locking the filter support frame 71 with the inner container 30, it is conducive to improving the assembly accuracy, assembly efficiency between the filter 7 and the inner container 30, and the structural strength of the locking structure between the filter support frame 71 and the inner container 30, to ensure the firmness after assembly.

[0090] Referring to Figure 3 As shown, the filter 7 also has an upper cover 73 buckled on the filter support frame 71, and the filter 7 has the upper cover 73, the filter support frame 71 and the cup-shaped filter screen 72 arranged in sequence from top to bottom, the water flow mixed with food residues passes through the filter support frame 71 into the cup-shaped filter screen 72, and the food residues are filtered, and then the water flow enters the water flow channel.

[0091] The rotational fixing direction of the cup-shaped filter screen 72 is opposite to the rotational fixing direction of the filter support frame 71. Furthermore, the rotational angle of the cup-shaped filter screen 72 during fixing is smaller than the rotational angle of the filter support frame 71 during fixing. Thus, when the cup-shaped filter screen 72 is fixed to the filter support frame 71 in the forward direction, and the filter support frame 71 is locked in the reverse direction when the filter 7 is locked, the cup-shaped filter screen 72 is stationary relative to the inner liner 30, and rotates in the opposite direction relative to the filter support frame 71. The forward rotation angle of the cup-shaped filter screen 72 during fixing to the filter support frame 71, combined with the reverse rotation when the filter 7 is locked, causes the cup-shaped filter screen 72 to rotate in the disassembly direction. By setting the rotational fixing angle of the cup-shaped filter screen 72 to be smaller than the rotational fixing angle of the filter support frame 71, the cup-shaped filter screen 72 remains fixed to the filter support frame 71 after the filter screen 7 is fixed to the inner liner 30, which helps increase the stability of the filter 7 after fixing.

[0092] See Figure 6 and Figure 7 As shown, for the rotational fixation between the cup-shaped filter screen 72 and the filter support frame 71, the cup-shaped filter screen 72 is provided with a stop 724, wherein the stop 724 has a stop bar 7241 protruding inward along the side wall of the cup-shaped filter screen 72, and a stop protrusion 7242 provided at the upper end of the stop bar 7241 and extending inward. The filter support frame 71 is provided with a radially extending retaining edge 712, which is located inside the cup-shaped filter screen 72. The retaining edge 712 has an arc-shaped first clearance opening 7121 that matches the stop bar 7241, and a second clearance opening 7122 that matches the stop protrusion 7242 at one end of the first clearance opening 7121. The retaining edge 712 includes a retaining edge body 7120, and a first clearance opening 7121 and a second clearance opening 7122 opened on the retaining edge body 7120. By setting a first clearance opening 7121 and a second clearance opening 7122, especially the second clearance opening 7122, when the cup-shaped filter screen 72 is assembled onto the filter support frame 71, the cup-shaped filter screen 72 is close to the filter support frame 71, causing the stop protrusion 7242 to be located within the second clearance opening 7122. At this time, the stop rod 7241 is located within the first clearance opening 7121, thus achieving the positioning of the cup-shaped filter screen 72. Then, by rotating, the stop rod 7241 rotates along the first clearance opening 7121, and the stop protrusion 7242 stops on the upper side of the retaining edge 712. This ensures that the stop claw 724 does not need to deform and engage during the rotation and fixing process, which is beneficial for the stop claw 724 to have greater structural strength and for improving the stability and firmness of the cup-shaped filter screen 72 after it is fixed to the filter support frame 71. Preferably, an upwardly extending limiting rib 7123 is provided at the other end of the first clearance opening 7121. The limiting rib 7123 is used to install and fix the guard 724 in place. When the guard 724 rotates to the limiting rib 7123, the cup-shaped filter screen 72 is installed in place.

[0093] Referring to Figure 15 and Figure 20 As shown in the figure, the filter device of the dishwasher further comprises a fan-shaped filter screen 8 arranged in the inner container 30, and a mounting opening 81 is formed on the fan-shaped filter screen 8, and the lower part of the filter 7 is fixed on the inner container 30 through the mounting opening 81.

By arranging the lower recess 811, after the assembly edge 713 cooperates with the mounting edge 812, the upper surface of the assembly edge 713 is lower than the upper surface of the fan-shaped filter screen 8 at the mounting opening 81, which is beneficial to the water flow entering the filter 7. After the filter 7 is installed on the inner container 30, the assembly edge 713 gives the mounting edge 812 a certain pressing force to ensure the sealing between the filter 7 and the mounting edge 812, but also to avoid excessive pressing force causing the mounting edge 812 to have a large downward deformation, which causes the edge of the fan-shaped filter screen 8 to be raised. Part of the water flow passes through the fan-shaped filter screen 8 into the water channel, and part of the water flow passes through the filter 7 into the water channel; the upper surface of the fan-shaped filter screen 8 is slightly inclined to the mounting opening 81, so that the food residues remaining on the fan-shaped filter screen 8 can enter the filter 7 with the water flow under the impact of the water flow. It is preferred that the filtering precision of the fan-shaped filter screen 8 is greater than that of the cup-shaped filter screen 72, which is beneficial to more water flow flowing to the filter 7, so that food residues are not retained on the fan-shaped filter screen 8.

[0094] Referring to Figure 13 and Figure 14 As shown in the figure, in order to form support for the fan-shaped filter screen 8, a concave water channel cavity is arranged at the bottom of the inner container 30, a pump shell 307 covers the water channel cavity, a concave filter mounting groove 3071 matched with the fan-shaped filter screen 8 is arranged on the pump shell 307, a water passing hole is formed at the bottom of the filter mounting groove 3071, and the fan-shaped filter screen 8 is installed in the filter mounting groove 3071. By arranging the filter mounting groove 3071, effective support for the fan-shaped filter screen 8 is formed, which effectively avoids the upward lifting of the edge of the fan-shaped filter screen 8, and is beneficial to improving the filtering efficiency. A third avoiding opening 30711 is formed at the bottom of the filter mounting groove 3071, and an avoiding edge 30712 inclined inwardly and downwardly is arranged at the edge of the third avoiding opening 30711. By arranging the inclined avoiding edge 30712, the assembly edge 713 gives the mounting edge 812 a certain pressing force to ensure the sealing between the filter 7 and the mounting edge 812.
