Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically to an improvement in the structure of a dishwasher. Background Technology

[0002] In the manufacturing process of a dishwasher, the base needs to be placed on a tooling plate for assembly and fixation first, and then the water system components, motor, power board and other components that make up the water system are placed on the base for assembly.

[0003] The water system components include a spray seat and a water collection cup. After the spray seat and water collection cup are placed on the base, the inner liner is installed, and the spray seat and water collection cup are locked and fixed to the inner liner. A first insert connector and a second insert connector are respectively provided on the spray seat and the water collection cup. A first insert hole and a second insert hole are provided on the inner liner to mate with the first insert connector and the second insert connector. During assembly, the first insert connector and the second insert connector need to be aligned with the first insert hole and the second insert hole simultaneously before they can be locked and fixed by the locking ring.

[0004] However, during assembly, due to positional deviations between the spray seat and the water collection cup, it is difficult to align the first plug-in connector with the first insertion hole and the second plug-in connector with the second insertion hole simultaneously. During assembly, it is necessary to first ensure that the inner liner is aligned with one of them, and then move the other one to repeatedly adjust its position to ensure that they are aligned at the same time, resulting in low assembly efficiency and low production efficiency.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] In view of the aforementioned technical problems in the installation of dishwasher water circuit components as pointed out in the background art, a dishwasher is proposed. By setting a first pre-positioning part and a second pre-positioning part on the base to cooperate with the first positioning part of the first water circuit component and the second positioning part of the second water circuit component respectively, the position between the first water circuit component and the second water circuit component can be positioned, thereby ensuring that the assembly hole above the inner tank can be quickly aligned with the connector, thus improving assembly efficiency.

[0007] A dishwasher includes: chassis; The inner tub component is arranged inside the casing, and its interior defines a washing space. A first mounting hole and a second mounting hole are provided on the inner tub component. A first water passage component, having a first connector portion that mates with the first assembly hole; and First positioning section; The second water passage component has a second connector portion that mates with the second assembly hole; and Second positioning section; A base is located below the inner liner component, and the base is provided with: The first pre-positioning unit and the second pre-positioning unit; The first pre-positioning part and the second pre-positioning part are configured to cooperate with the first positioning part and the second positioning part respectively to pre-position the positions of the first water passage component and the second water passage component, such that the distance between the centers of the first connector part and the second connector part is equal to the distance between the centers of the first assembly hole and the second assembly hole.

[0008] The above embodiments have the following advantages and effects: The dishwasher in this embodiment, through the first and second pre-positioning parts provided on the base, can cooperate with the first and second positioning parts on the first water passage component to pre-position the positions of the first and second water passage components. This ensures that the distance from the center of the first connector on the pre-positioned first water passage component to the center of the second connector on the second water passage component is equal to the distance between the centers of the first and second mounting holes on the inner liner component. Thus, when the inner liner component is assembled with the first and second water passage components, as long as one mounting hole on the inner liner component is aligned with the connector, the other mounting hole is also aligned. This achieves rapid alignment of the first and second mounting holes on the inner liner component with the first and second connectors, avoiding the problem of alignment difficulties caused by positional deviations between the first and second water passage components and improving assembly efficiency. In addition, by setting the first prepositioning part and the second prepositioning part, the first water passage component and the second water passage component can be supported, making it more convenient to connect the inner liner component with the two water passage components.

[0009] In some embodiments of this application, the first positioning part is a first positioning protrusion; The first pre-positioning part includes: a first pre-positioning body; A first insert portion having an opening is formed on the first prepositioning body, and a first limiting portion for limiting the first positioning portion is formed on the inner wall of the first insert portion; During pre-positioning, the first positioning protrusion is inserted into the first insertion part, with its bottom limited by the bottom wall of the first insertion part and its circumference limited by the first limiting part.

[0010] The above embodiments have the following advantages and effects: By setting the first prepositioning part on the base as the first insertion part and setting the first positioning part on the first water channel component as the first positioning protrusion structure, when prepositioning the first water channel component, it is only necessary to insert the first positioning protrusion into the first insertion part from the opening, making the prepositioning assembly convenient and quick.

[0011] In some embodiments of this application, the second positioning part is a second positioning protrusion; The second prepositioning part includes a second prepositioning body and a second insertion part formed on the second prepositioning body, and a second limiting part for limiting the second positioning protrusion is formed on the inner wall of the second insertion part; During pre-positioning, the second positioning protrusion is inserted into the second insertion part, with its bottom limited by the bottom wall of the second insertion part and its circumference limited by the second limiting part.

[0012] The above embodiments have the following advantages and effects: By setting the second prepositioning part on the base as the second insertion part and setting the second positioning part on the second water channel component as the second positioning protrusion structure, when prepositioning the second water channel component, it is only necessary to insert the second positioning protrusion into the second insertion part, making the prepositioning assembly convenient and quick.

[0013] In some embodiments of this application, a support portion is formed on the base, and one or more support portions are provided for supporting the first water passage component and / or the second water passage component.

[0014] The above embodiments have the following advantages and effects: The support portion provided on the base can be used to support and bear the weight of the first water passage component and / or the second water passage component, preventing the first water passage component and / or the second water passage component from tilting and moving due to uneven weight, thus affecting their alignment with the second mounting hole on the inner liner component.

[0015] In some embodiments of this application, a first connecting portion is formed on the first waterway component; A second connection portion is formed on the second waterway component, and the second connection portion is used to connect with the first connection portion to achieve a pre-connection with the first waterway component.

[0016] The above embodiments have the following advantages and effects: The first water passage component and the second water passage component can be pre-connected by the first connecting part on the first water passage component and the second connecting part on the second water passage component. During installation, the first water passage component and the second water passage component can be pre-connected first, and then the two can be inserted and positioned as a whole onto the base. Compared with the method of installing the first water passage component and the second water passage component one by one, the installation operation steps are saved and the installation efficiency is improved.

[0017] In some embodiments of this application, the first connecting portion is an insert / slot formed on the first water passage component, and the second connecting portion is a slot / insert formed on the second water passage component.

[0018] The above embodiments have the following advantages and effects: By configuring the first connecting part and the second connecting part into a structure in which inserts and slots cooperate, rapid pre-connection between the first water channel component and the second water channel component can be achieved.

[0019] In some embodiments of this application, an elastic extension is formed on the second waterway component, the slot is formed on the extension, and a slot opening is formed on one side of the slot.

[0020] The above embodiments have the following advantages and effects: By forming a slot directly on the elastic extension of the second water channel component, the molding process is convenient and the process is simplified. A slot opening is provided on one side of the slot, which allows the insert to be easily inserted into the slot for fitting.

[0021] In some embodiments of this application, the insert is formed on the first waterway component, and the insert includes: The insert body has a maximum outer diameter larger than the slot opening diameter; and An insertion limiting portion is formed on the body of the insert; When the insert body is inserted into the slot, the elastic extension is positioned between the insert limiting part and the first water passage component.

[0022] The above embodiments have the following advantages and effects: By setting the outer diameter of the insert body to be larger than the diameter of the slot opening, the elastic extension at the slot opening can deform when the insert body mates with the slot and passes through the slot opening. When the insert body is inserted into the slot, the slot opening restores its deformation and limits the insert body to be in the slot. At the same time, the elastic extension is also limited by the insertion limiting part on the insert body and the first water channel component, so as to realize the connection between the first water channel component and the second water channel component.

[0023] In some embodiments of this application, a locking assembly is included, the locking assembly comprising: The first locking component is engaged around the first mounting hole and is used to be screwed into the first connector to connect the first water passage component and the inner tank component. When the first locking component is screwed into place, the first water passage component is locked onto the inner liner component, and the first positioning part and the first pre-positioning part above it disengage.

[0024] The above embodiments have the following advantages and effects: By setting the first locking component to cooperate with the first water passage component, the first water passage component is locked onto the inner tank component. During the locking process, the first water passage component can be moved upward, so that the first water passage component is separated from the base, effectively blocking the transmission of noise and ensuring the performance of the entire dishwasher.

[0025] In some embodiments of this application, the locking assembly includes: a second locking component, which is engaged around the second mounting hole and is used to screw onto the second connector to connect the second water passage component and the inner tank component; When the second locking component is screwed into place, the second water passage component is locked onto the inner liner component, and the second positioning part is disengaged from the second pre-positioning part.

[0026] The second locking component works in conjunction with the second water channel component. When the second water channel component is locked, it moves upward and separates from the base, thus isolating the base from the second water channel component and preventing noise from being transmitted to the base, which would affect the performance of the whole machine.

[0037] In some embodiments of this application, a dishwasher is proposed, which is mainly used for cleaning tableware that needs to be washed.

[0038] The dishwasher includes a housing and an inner tub component 100 disposed within the housing. A base 300 is disposed below the inner tub component 100 to support and carry the entire dishwasher.

[0039] The inner tank component 100 defines a washing space, where the tableware is primarily washed.

[0040] An opening is formed on one side of the washing space, and a pull-out dish basket is provided on the inner liner component 100. The dish basket can extend out from the opening. The dish basket is mainly used to hold tableware. Tableware that needs to be washed or tableware that has been washed can be placed or taken out by pulling the dish basket relative to the opening.

[0041] A door is rotatably connected to the casing at the opening, and the door is used to open or close the washing space.

[0042] A water system component 200 is provided on the base 300, which can clean the tableware in the washing space.

[0043] In some embodiments of this application, reference is made to Figure 10-11 As shown, the inner liner component 100 is provided with assembly holes including a first assembly hole 110 and a second assembly hole 120, and the water passage component 200 is provided with a first connector portion 211 and a second connector portion 221, which cooperate with the first assembly hole 110 and the second assembly hole 120.

[0044] The waterway component 200 includes a first waterway component 210 and a second waterway component 220. A first connector 211 is provided on the first waterway component 210, and a second connector 221 is provided on the second waterway component 220.

[0045] In the existing assembly method, the first water passage component 210 and the second water passage component 220 are first placed on the base 300, and then the first assembly hole 110 and the second assembly hole 120 on the inner liner component 100 are aligned with the first joint portion 211 and the second joint portion 221 on the first water passage component 210 and the second water passage component 221 respectively, and then locked and fixed.

[0046] However, due to the positional deviation of the first water passage component 210 and the second water passage component 220 on the base 300, it is difficult for the inner liner component 100 to be simultaneously aligned with the first joint portion 211 and the second joint portion 221 on the first water passage component 210 and the second water passage component 220 during assembly.

[0047] To address the aforementioned problems, in some embodiments of this application, reference is made to... Figure 1-4 As shown, A first positioning part 212 is provided on the first water channel component 210, a second positioning part 222 is provided on the second water channel component 220, and a first pre-positioning part and a second pre-positioning part are correspondingly arranged on the base 300.

[0048] The first pre-positioning part 310 is used to cooperate with the first positioning part 212 to pre-position the first water channel component 210. The cooperation between the first pre-positioning part 310 and the first positioning part 212 can ensure the accuracy of the position of the first water channel component 210 on the base 300.

[0049] The second pre-positioning part 320 is used to cooperate with the second positioning part 222 to pre-position the second water channel component 220. The cooperation between the second pre-positioning part 320 and the second positioning part 222 can ensure the accuracy of the position of the second water channel component 220 on the base 300.

[0050] The first prepositioning part 310 and the second prepositioning part 320 are configured to cooperate with the first positioning part 212 and the second positioning part 222 respectively to preposition the positions of the first water passage component 210 and the second water passage component 220, such that the distance between the centers of the first connector part 211 and the second connector part 221 is equal to the distance between the centers of the first assembly hole 110 and the second assembly hole 120.

[0051] The above embodiments have the following advantages and effects: In this embodiment, the dishwasher, by providing a first pre-positioning part 310 and a second pre-positioning part 320 on the base 300, can be used to cooperate with the first positioning part 212 and the second positioning part 222 on the first water passage component 210 to achieve pre-positioning of the positions of the first water passage component 210 and the second water passage component 220.

[0052] By pre-positioning the first water passage component 210 and the second water passage component 220, the distance from the center of the first connector 211 on the pre-positioned first water passage component 219 to the center of the second connector 221 on the second water passage component 220 is equal to the distance between the centers of the first assembly hole 110 and the second assembly hole 120 on the inner liner component 100. Thus, when the inner liner component 100 is assembled and connected with the first water passage component 210 and the second water passage component 220, as long as one of the assembly holes on the inner liner component 100 is aligned with the connector, the other assembly hole is also aligned. This achieves rapid alignment of the first assembly hole 110 and the second assembly hole 120 on the inner liner component 100 with the first connector 211 and the second connector 221, avoiding the problem of alignment difficulties caused by positional deviations between the first water passage component 210 and the second water passage component 220, and improving assembly efficiency. In addition, by setting the first prepositioning part 310 and the second prepositioning part 320, the first water passage component 210 and the second water passage component 220 can be supported, making it easier to install the inner liner component 100 and the two water passage components.

The first limiting protrusion is provided with a plurality of protrusions arranged circumferentially along the first insertion hole to limit the first positioning part 212 inserted into the first insertion part 312 around the periphery.

[0062] The first positioning protrusion has a cross-sectional shape of cylindrical, elliptical, or quadrilateral, etc. The above embodiments have the following advantages and effects: By setting the first prepositioning part 310 on the base 300 as the first insertion part 312 and setting the first positioning part 212 on the first water passage component 210 as the first positioning protrusion structure, when prepositioning the first water passage component 210, it is only necessary to insert the first positioning protrusion into the first insertion part 312 from the opening, making the prepositioning assembly convenient and quick.

[0063] In some embodiments of this application, the second water passage component 220 is a water collecting cup, and the second connector 221 is a second connector cylinder formed on the water collecting cup. When it mates with the second mounting hole 120 on the inner liner component 100, it is inserted into the second mounting hole 120.

[0064] The second prepositioning part 320 is used to position the second positioning part 222 on the water collecting cup so that when the water collecting cup is assembled with the inner liner component 100, the second connector part 221 above it can be aligned with the second mounting hole 120 to achieve quick installation.

[0065] In some embodiments of this application, one second positioning part 222 is provided, and one corresponding second pre-positioning part 320 is provided.

[0066] In some embodiments of this application, multiple second positioning parts 222 are provided and arranged at the bottom of the spray seat, along the circumference of the spray seat, and multiple second pre-positioning parts 320 are provided, each cooperating with multiple second positioning parts 222.

[0067] By setting up multiple second positioning parts 222 and multiple second pre-positioning parts 320 in cooperation, the second waterway component 220 can be accurately positioned.

[0068] In some embodiments of this application, reference is made to Figure 9 As shown, the second positioning part 222 is a second positioning protrusion.

[0069] Reference Figure 3 As shown, the second prepositioning part 320 includes a second prepositioning body 321 and a second insertion part 322 formed on the second prepositioning body 321. A second limiting part 323 for limiting the second positioning protrusion is formed on the inner wall of the second insertion part 322. During pre-positioning, the second positioning protrusion is inserted into the second insertion part 322, and its circumference is limited by the second limiting part 323.

[0070] Before being assembled with the inner liner component 100, the second water passage component 220 is first inserted into the second insertion part 322 on the base 300 through the second positioning protrusion on its upper part. The bottom and the periphery of the second positioning protrusion are both limited and positioned. When the second positioning protrusion is limited, the positioning of the second water passage component 220 connected to it is also realized accordingly.

[0071] In some embodiments of this application, the second insertion portion 322 is a second insertion blind hole formed on the second prepositioning body 321, and the second limiting portion 323 is a second limiting protrusion formed on the inner wall of the second insertion blind hole. The second limiting protrusion is provided with a plurality of protrusions arranged circumferentially along the second insertion hole to limit the second positioning portion 222 inserted into the second insertion portion 322 around the periphery.

[0072] The second positioning protrusion can have a cross-sectional shape of cylinder, ellipse or quadrilateral, etc.

[0073] The above embodiments have the following advantages and effects: By setting the second prepositioning part 320 on the base 300 as the second insertion part 322 and setting the second positioning part 222 on the second water passage component 220 as the second positioning protrusion structure, when prepositioning the second water passage component 220, it is only necessary to insert the second positioning protrusion into the second insertion part 322, making the prepositioning assembly convenient and quick.

During installation, the first water passage component 210 and the second water passage component 220 can be pre-connected first, and then the two can be inserted and positioned as a whole onto the base 300. Compared with the method of installing the first water passage component 210 and the second water passage component 220 one by one, the installation operation steps are saved and the installation efficiency is improved.

[0080] In some embodiments of this application, reference is made to Figure 5-10 As shown, the first connecting part is an insert 213 / slot 223 formed on the first water passage component 210, and the second connecting part is a slot 223 / insert 213 formed on the second water passage component 220.

[0081] In some embodiments of this application, the first connecting part is a slot 223 provided on the second water passage component 220, and the second connecting part is an insert 213 provided on the first water passage component 210.

[0082] Reference Figure 9-10 As shown, an elastic extension 225 is formed on the second water channel component 220. The elastic extension 225 is made of plastic material. The slot 223 is formed on the elastic extension 225. The slot 223 has a slot opening 224 on one side.

[0083] Reference Figures 7-8 As shown, the insert 213 includes an insert body 2131 and an insert limiting portion 2132 formed on the insert body 2131.

[0084] The diameter of the slot 224 is smaller than the outer diameter of the insert body 2131.

[0085] When the insert body 2131 is inserted into the slot 223 through the slot opening 224, it will deform as it passes through the slot opening 224. Since the diameter of the slot opening 224 is smaller than the outer diameter of the insert body 2131 and the material is plastic, the insert body 2131 is inserted into the slot 223. After the insert body 2131 passes through the slot opening 224, the slot opening 224 returns to its original shape, thus limiting the insert body 2131 within the slot 223.

[0086] Reference Figure 6 As shown, when the insert body 2131 is inserted into the slot 223, the elastic extension 225 is sandwiched between the insertion limiting part 2132 and the second water channel component 220, and is positioned by the insertion limiting part 2132 and the first water channel component 210.

[0087] The above embodiments have the following advantages and effects: By configuring the first connecting part and the second connecting part into a structure in which the insert 213 and the slot 223 cooperate, a quick pre-connection between the first water channel component 210 and the second water channel component 220 can be achieved.

[0088] In some embodiments of this application, the dishwasher includes: a locking assembly, as shown in the reference. Figure 11-12 As shown, the locking assembly includes: The first locking component 410 is engaged around the first mounting hole 110 and is used to be screwed into the first connector 211 to connect the first water passage component 210 and the inner liner component 100. When the first locking component 410 is screwed into place, the first water passage component 210 is locked onto the inner liner component 100, and the first positioning part 212 and the first pre-positioning part 310 above it disengage.

[0089] The first locking component 410 is a first locking ring, which includes a first ring body and a first flange disposed around the periphery of the first ring body, and an internal thread is provided in the first ring body.

[0090] A first mounting platform 111 is formed around the first mounting hole 110.

[0091] The first connector 211 is inserted into and extends out of the first mounting hole 110.

[0092] When the first locking ring is locked, it is engaged on the first locking platform 111 by the first flange. The first ring body is screwed onto the first connector 211 by the internal thread. As the first locking ring rotates continuously, it drives the first water passage component 210 to move upward, so that the first positioning part 212 and the first pre-positioning part 310 are separated.

[0093] Water circuit component 200 is a water circuit component that constitutes the water circuit system. During the operation of the water circuit system, slight vibrations will be generated. If the water circuit component 200 and the pre-positioning structure on the base 300 remain in contact, the vibration will be transmitted to the base 300, and then transmitted to the whole machine, generating noise and affecting the performance of the whole machine.

[0094] The first locking component is engaged with the first mounting hole and threaded with the first water passage component 210, so that when the first water passage component 210 is locked, it can be raised relative to the base 300 and disengaged from the base 300, effectively blocking the transmission of noise and ensuring the overall performance of the dishwasher.

[0095] In some embodiments of this application, the locking assembly includes: a second locking component 420, which is engaged around the second mounting hole 120 and is used to be screwed onto the second connector 221 to connect the second water passage component 220 and the inner liner component 100; When the second locking component 420 is screwed into place, the second water passage component 220 is locked onto the inner liner component 100, and the second positioning part 222 disengages from the second pre-positioning part 320.

[0096] The second locking component 420 is a second locking ring, which includes a second ring body and a second flange disposed around the periphery of the second ring body, and an external thread is provided on the outer wall of the second ring body.

[0097] A second mounting platform 121 is formed around the second mounting hole 120.

[0098] The second connector 221 is inserted into the second assembly hole 120, and an internal thread is provided inside the second connector 221.

[0099] When the second locking ring is locked, it is engaged on the second locking platform 121 by the second flange. The body of the second ring is screwed into the internal thread in the first joint 211 by the external thread. As the second locking ring rotates continuously, it drives the second water passage component 220 to move upward, so that the second positioning part 222 and the second pre-positioning part 320 are separated.

[0100] The above embodiments have the following advantages and effects: The second locking component 420 cooperates with the second water channel component 220. When the second water channel component 220 is locked, it moves the second water channel component 220 upward and separates it from the base 300, thus separating the base 300 from the second water channel component 220 and preventing noise from being transmitted to the base 300 and affecting the performance of the whole machine.

[0101] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0102] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
