[0073] Reference Figures 1-20It is an embodiment of the filter device of the dishwasher provided by the application, and the filter device of the dishwasher comprises a filter 7 for collecting residues, the filter 7 has a filter support frame 71 and a cup-shaped filter screen 72 rotatably fixed to the filter support frame 71; 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 rotatably fixed with the inner container 30. By rotatably fixing the cup-shaped filter screen 72 to the filter support frame 71, the assembly speed of the filter 7 during assembly is improved, and the stability after rotation is fixed is improved. By rotatably locking the filter support frame 71 and the inner container 30, the assembly precision and efficiency between the filter 7 and the inner container 30 are improved, and the structural strength of the locking structure between the filter support frame 71 and the inner container 30 is improved, thereby ensuring the firmness after assembly.

[0074] Referring to Figure 13 As shown in the figure, 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 enters the cup-shaped filter screen 72 through the filter support frame 71, so as to realize the filtration of food residues, and then the water flow enters the water flow channel.

[0075] The rotation fixing direction of the cup-shaped filter screen 72 is opposite to the rotation direction of the installation and fixation of the filter support frame 71. And the rotation angle of the cup-shaped filter screen 72 during rotation fixation is less than the rotation angle of the filter support frame 71 during installation and fixation. In this way, the cup-shaped filter screen 72 is forwardly rotatably fixed to the filter support frame 71, and when the filter 7 is rotatably locked on the inner container 30, the filter support frame 71 is reversely rotatably locked, at this time, the cup-shaped filter screen 72 is stationary relative to the inner container 30, and the cup-shaped filter screen 72 is reversely rotatable relative to the filter support frame 71. The installation and fixation of the cup-shaped filter screen 72 and the filter support frame 71 make the angle of forward rotation, and when the filter 7 is rotatably locked, the cup-shaped filter screen 72 is rotatable in the disassembly direction due to the reverse rotation. By setting the rotation angle of the cup-shaped filter screen 72 during rotation fixation to be less than the rotation angle of the filter support frame 71 during installation and fixation, the cup-shaped filter screen 72 is also fixed on the filter support frame 71 after the filter 7 is fixed on the inner container 30, which is beneficial to increase the stability of the filter 7 after fixation.

[0076] Referring to Figure 16 and Figure 17As shown, for the rotation fixation between the cup-shaped filter screen 72 and the filter support frame 71, the cup-shaped filter screen 72 is provided with a blocking claw 724, wherein the blocking claw 724 has an inwardly protruding blocking rod 7241 arranged along the sidewall of the cup-shaped filter screen 72, and a blocking protrusion 7242 arranged at the upper end of the blocking rod 7241 and extending inwardly. The filter support frame 71 is provided with a radially extending clamping edge 712 located at the inner side of the cup-shaped filter screen 72, and the clamping edge 712 is provided with an arc-shaped first avoiding opening 7121 matched with the blocking rod 7241 and a second avoiding opening 7122 matched with the blocking protrusion 7242 arranged at one end of the first avoiding opening 7121. The clamping edge 712 comprises a clamping edge body 7120 and the first avoiding opening 7121 and the second avoiding opening 7122 arranged on the clamping edge body 7120. By arranging the first avoiding opening 7121 and the second avoiding opening 7122, especially the second avoiding opening 7122, when the cup-shaped filter screen 72 is assembled to the filter support frame 71, the cup-shaped filter screen 72 is close to the filter support frame 71 so that the blocking protrusion 7242 is located in the second avoiding opening 7122, and at this time, the blocking rod 7241 is located in the first avoiding opening 7121, thereby realizing the positioning of the cup-shaped filter screen 72. Then, the cup-shaped filter screen 72 is rotated so that the blocking rod 7241 rotates along the first avoiding opening 7121, and the blocking protrusion 7242 is blocked at the upper side of the clamping edge 712, thereby realizing that the blocking claw 724 does not need to be deformed during the rotation fixation, which is beneficial to arrange the blocking claw 724 to have a larger structural strength and is beneficial to improve the stability and firmness of the cup-shaped filter screen 72 after being fixed to the filter support frame 71. Preferably, a limiting rib 7123 extending upwardly is arranged at the other end of the first avoiding opening 7121, and the limiting rib 7123 is used for installing and fixing the blocking claw 724 in place; when the blocking claw 724 rotates to the limiting rib 7123, the cup-shaped filter screen 72 is installed in place.

[0077] Referring to Figure 5 and Figure 10As shown, 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 in the fan-shaped filter screen 8, and the lower part of the filter 7 is fixed to the inner container 30 through the mounting opening 81. A downwardly inclined lower recess 811 is arranged in the mounting opening 81, and a mounting flange 812 extending inwardly is arranged at the lower end of the lower recess 811, and the filter 7 is pressed against the mounting flange 812, so as to ensure the sealing between the filter 7 and the filter 8. The filter support frame 71 has a radially outwardly extending assembly flange 713, which is arranged above the clamping flange 712, and the assembly flange 713 is sealingly arranged above the mounting flange 812. By arranging the lower recess 811, after the assembly flange 713 cooperates with the mounting flange 812, the upper surface of the assembly flange 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 to the inner container 30, the assembly flange 713 gives a certain pressing force to the mounting flange 812, so as to ensure the sealing between the filter 7 and the mounting flange 812, but also to avoid that the pressing force is too large to cause the mounting flange 812 to have a large deformation downwardly, so as to cause 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 to enter the water channel, and part of the water flow passes through the filter 7 to enter 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 under the impact of the water flow flowing to the filter 7. 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 the food residues are not retained on the fan-shaped filter screen 8.

[0078] As shown in Figure 3 and Figure 4 As shown, in order to form the support for the fan-shaped filter screen 8, a concave water channel cavity is arranged at the bottom of the inner container 30, and a pump shell 307 covers the water channel cavity, and a concave filter mounting groove 3071 matched with the fan-shaped filter screen 8 is arranged on the pump shell 307, and a water passing hole is formed at the bottom of the filter mounting groove 3071, and the fan-shaped filter screen 8 is arranged 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 raising 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 flange 30712 inclined inwardly and downwardly is arranged at the edge of the third avoiding opening 30711, and by arranging the avoiding flange 30712, the assembly flange 713 gives a certain pressing force to the mounting flange 812, so as to ensure the sealing between the filter 7 and the mounting flange 812.

[0079] The lower side of the assembly along 713 is provided with a first limiting claw 714 extending downward, the mounting opening 81 is provided with a supporting plate 814 extending downward, the supporting plate 814 is provided with a first limiting plate 815 matched with the first limiting claw 714, and the first limiting plate 815 protrudes inward. The bottom edge of the cup-shaped filter screen 72 is provided with a supporting edge 723 extending downward, the bottom of the inner container 30 is provided with a water tank 305 for accommodating the cup-shaped filter screen 72, and the bottom of the water tank 305 is provided with an annular groove 3052 concave, and the supporting edge 723 is located in the annular groove 3052. By arranging the supporting edge 723 and the annular groove 3052, the structural strength of the cup-shaped filter screen 72 can be increased, and the positioning and fixing of the cup-shaped filter screen 72 are facilitated.

[0080] The inner container 30 of the dishwasher is provided with a concave water tank 305, and a locking structure is arranged between the bottom surface of the water tank 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 tank 305, the locking structure has a larger arrangement space, a more stable 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 tank 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 food residues entering the water channel due to a large assembly gap can be avoided.

[0081] Referring to Figure 4 , Figure 8 , and Figure 14As 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, and the first locking members 3051 and the second locking members 711 are rotationally locked; since the cup-shaped filter screen 72 is located at the lower part 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.

[0082] Referring to Figure 4 As shown, the first locking member 3051 has a first supporting part 30511 extending upwardly along the bottom surface of the water tank 305, a first claw part 30512 extending horizontally along the top end of the first supporting part 30511, and a reinforcing part 30513 arranged outside the first supporting part 30511 and the first claw part 30512, the lower end of the reinforcing part 30513 is connected with the bottom surface of the water tank 305, and the reinforcing part 30513 is an arc surface. By setting the reinforcing part 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.

[0083] Referring to Figure 14As 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 rotary 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,

[0084] Referring to Figure 17 and Figure 18 As shown, 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.

[0085] Referring to Figure 10 and Figure 18As 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.
