Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to a dishwasher with a height adjustment device. Background Art

[0002] With the improvement of people's living standards and the change of consumption concepts, dishwashers have gradually entered many families. As a household appliance that liberates people's hands, dishwashers are used by more and more users, overcoming the problems of uncleanliness, unhygienic conditions, time-consuming and laborious handwashing of tableware.

[0003] In existing dishwashers, in order to adapt to cabinets of different heights or the needs of different users, multiple adjustable-height feet are installed at the bottom of the dishwasher to adjust the height of the dishwasher.

[0004] However, during the height adjustment of the dishwasher, adjusting each foot separately not only results in low installation efficiency, but also makes it difficult to adjust each foot to the same height, resulting in poor stability of the liftable dishwasher. Summary of the Utility Model

[0005] This application provides a dishwasher with a height adjustment device to solve the problem of how to improve the stability of the liftable dishwasher.

[0006] In some embodiments of this application, a dishwasher with a height adjustment device includes: a main body, a base, and a height adjustment device. A cleaning inner tank is provided in the main body; a recess is provided on the base, the main body is arranged in the recess, and a telescopic opening communicating with the recess is further provided on the base. The height adjustment device is at least partially arranged in the recess, and the height adjustment device includes: a worm gear, a screw rod, and a worm. The worm gear is rotatably arranged on the base, and the rotation axis of the worm gear is perpendicular to the base; the screw rod is arranged at the telescopic opening; the worm gear is sleeved on the screw rod and is in transmission connection with the screw rod; one end of the worm is in transmission connection with the worm gear, and the other end of the worm is fixedly connected with a bevel gear; when the bevel gear rotates, it drives the worm gear to rotate, so that the screw rod passes through the telescopic opening for spiral lifting movement, driving the base to lift; multiple groups of height adjustment devices are provided, and the multiple groups of height adjustment devices are arranged at intervals on the base, and the bevel gears of the multiple groups of height adjustment devices are engaged, wherein, at least one group of the worm of the height adjustment device extends out of the recess.

[0007] It can be understood that when the height of the dishwasher needs to be adjusted, the user can rotate the screw rod extending out of the recessed part. This screw rod can drive other screw rods meshing with it to rotate, causing all the screw rods to rotate simultaneously. Then, the other end of the screw rod drives the worm wheel to rotate, and finally drives the screw rod connected to the worm wheel to perform a spiral lifting and lowering movement. At this time, the worm wheel is connected to the base of the dishwasher, and the screw rod moves up and down relative to the base, thereby lifting and lowering the main body and the base of the dishwasher. Connecting the screw rods of multiple height adjustment devices through bevel gears enables the user to control the lifting and lowering of all height adjustment devices simultaneously by controlling one screw rod, and the lifting and lowering heights are the same, making the height adjustment devices of the dishwasher at the same height, improving the convenience for the user to control the height of the dishwasher and the stability when the dishwasher is placed.

[0008] In some embodiments of the present application, the base further includes: a fixing member disposed within the recessed part and fixedly connected to the base. The fixing member is provided with a lifting hole corresponding to the telescopic opening; the worm wheel is disposed within the fixing member to enable the worm wheel to rotate about its rotation axis, and the screw rod passes through the lifting hole.

[0009] In this way, the fixing member can enable the worm wheel to rotate about its rotation axis, preventing the worm wheel from shifting during rotation. Passing the screw rod through the lifting hole can also limit the screw rod, preventing the screw rod from shifting, resulting in deviations in the height adjustment device and inconsistent lifting heights of the dishwasher, further improving the stability of the dishwasher during the lifting process.

[0010] In some embodiments of the present application, the fixing member includes: a frame body, a first limiting plate, and a second limiting plate. The frame body is fixedly connected to the base; the first limiting plate is connected to the frame body, and the first limiting plate is provided with a first lifting hole; the second limiting plate is connected to the frame body, and the second limiting plate is provided with a second lifting hole. The first limiting plate and the second limiting plate are spaced apart, and the first lifting hole and the second lifting hole are correspondingly arranged; the worm wheel is disposed between the first limiting plate and the second limiting plate to enable the worm wheel to rotate about its rotation axis, and the screw rod passes through the first lifting hole and the second lifting hole.

[0011] In this way, the first limiting plate and the second limiting plate can limit the worm wheel, preventing the worm wheel from moving along its rotation axis direction, enabling the worm wheel to rotate about its rotation axis. Moreover, the frame body is fixedly connected to the base, further fixing the worm wheel. The screw rod passes through the first lifting hole and the second lifting hole, enabling the screw rod to move up and down relative to the base, improving the stability of the dishwasher during the lifting process. Additionally, the internal space enclosed by the frame body, the first limiting plate, and the second limiting plate can also protect the worm wheel from the external environment.

[0012] In some embodiments of the present application, the base further includes: a support cylinder, which is arranged on the side of the fixing member close to the body. One end of the support cylinder is connected to the fixing member, and the other end of the support cylinder is connected to the body; a lifting channel is formed in the support cylinder, the lifting channel is communicated with the lifting hole, and a screw rod is arranged in the lifting channel, and the screw rod can perform spiral lifting movement in the lifting channel.

[0013] In this way, the support cylinder connects the base and the body, preventing the body from shaking during the lifting and lowering of the height control component. The support cylinder can also protect the screw rod from the external environment and prevent foreign objects from affecting the normal operation of the screw rod.

[0014] In some embodiments of the present application, the height adjustment device further includes: a transmission member, which is arranged at one end of the screw rod of the height adjustment component extending out of the recessed part, and the transmission member is used to transmit power for the rotation of the screw rod.

[0015] In this way, the user can control the rotation of the screw rod by controlling the rotating member, and then control multiple groups of height adjustment devices to raise or lower the height of the dishwasher, improving the convenience of the user to adjust the height of the dishwasher.

[0016] In some embodiments of the present application, when the transmission member rotates, the screw rods of multiple groups of height adjustment devices rise or fall synchronously.

[0017] In this way, the screw rods of multiple groups of height adjustment devices rise or fall synchronously, which can ensure the stability of the dishwasher during the lifting process, prevent the dishwasher from shaking due to inconsistent heights of each group of height adjustment devices, and improve the smoothness of the dishwasher during the lifting process.

[0018] In some embodiments of the present application, the height adjustment device further includes: a limiting member, which is connected to the base, and the limiting member is used to limit the worm so that the worm rotates along its rotation axis.

[0019] In this way, the limiting member can make the worm rotate around its rotation axis, preventing the worm from displacing during the rotation process, causing deviation in the height adjustment device, and making the lifting heights of the height adjustment devices of the dishwasher inconsistent, further improving the smoothness of the dishwasher during the lifting process.

[0020] In some embodiments of the present application, the height adjustment device further includes: a foot, which is arranged at one end of the screw rod away from the body, the foot is connected to the screw rod, and the foot is used to abut against the placement surface of the dishwasher; the base further includes: a placement hole, which is arranged on the side of the base away from the body, the placement hole is correspondingly arranged with the foot, the placement hole is used to place the foot, and the placement hole is communicated with the fixing member.

[0021] In this way, the feet can support the dishwasher, making the placement of the dishwasher more stable. Also, it can prevent the screw from directly contacting the placement surface, which may cause damage to the screw and affect the normal operation of the height adjustment device. When the height adjustment device is not needed, the feet can be placed in the placement holes, enabling the dishwasher to be stably placed in a cabinet or other locations, avoiding impact on the feet and making the placement of the dishwasher more stable.

[0022] In some embodiments of the present application, multiple sets of height adjustment devices are respectively a first height adjustment device, a second height adjustment device, and a third height adjustment device. The three sets of height adjustment devices are arranged at triangular intervals on the base. The first height adjustment device and the second height adjustment device are arranged at the edges of the recessed part. The distance from the third height adjustment component to the first height adjustment device and the second height adjustment device is equal, and the screw of the third height adjustment component extends out of the recessed part.

[0023] It can be understood that arranging the three sets of height adjustment devices at triangular intervals on the base can improve the stability of the main body. Setting the distance from the third height adjustment component to the first height adjustment device and the second height adjustment device to be equal can make the pressure transmitted from the main body to the height adjustment devices more uniform, avoiding damage or breakage of one of the height adjustment devices due to excessive force on it, and preventing the inconsistent lifting height of the dishwasher main body from causing shaking, thus improving the stability of the dishwasher main body.

[0044] With the improvement of people's living standards and the change of consumption concepts, the dishwasher 100 has gradually entered many families. As a household appliance that liberates people's hands, the dishwasher 100 is used by more and more users, overcoming the problems of uncleanliness, unsanitary conditions, and time-consuming and laborious handwashing of tableware.

[0045] In the existing dishwasher 100, in order to adapt to different heights of cabinets or the needs of different users, a plurality of feet with adjustable heights are installed at the bottom of the dishwasher 100 to adjust the height of the dishwasher 100.

[0046] However, during the installation process of the dishwasher 100, adjusting each foot separately not only results in low installation efficiency, but also it is not easy to adjust each foot to the same height, resulting in poor stability of the liftable dishwasher 100.

[0047] Based on this, as Figure 1 shown, the present application provides a dishwasher 100 with a height adjustment device 20, including: a main body, a base 10, and a height adjustment device 20. A cleaning inner tank is provided inside the main body.

[0048] Among them, a sprayer is usually further provided inside the cleaning inner tank. The sprayer rotates to achieve spraying in all directions. There are mainly two types of sprayers: the first is a bottom sprayer installed at the bottom of the cleaning inner tank, which sprays from bottom to top under the action of water pressure; the other is a middle sprayer installed in the middle of the cleaning inner tank, which sprays from top to bottom under the action of water pressure. These two types of sprayers rotate under the reaction force of water pressure, so that they can spray the dishes that need to be cleaned in the cleaning inner tank, and then clean the dishes. The present application does not limit the types of sprayers.

[0049] As Figure 2As shown, a recess 11 is formed on the base 10, the body is disposed within the recess 11, and a telescopic opening 12 communicating with the recess 11 is further formed on the base 10.

[0050] Among them, as Figure 2 shown, the body is connected to the base 10, the base 10 is used to support the body, the base 10 includes a bottom plate 13 and a plurality of side plates 14. The plurality of side plates 14 are connected end to end, and the plurality of side plates 14 are all connected to the bottom plate 13. The space enclosed by the plurality of side plates 14 and the bottom plate 13 is the recess 11. The recess 11 can prevent the body from being affected by the external environment. The base 10 can be made of materials such as stainless steel, plastic or ceramic, and the present application does not limit this.

[0051] As Figure 3 shown, the height adjustment device 20 is at least partially disposed within the recess 11. The height adjustment device 20 includes: a worm gear 21, a screw rod 22 and a worm 23.

[0052] The worm gear 21 is rotatably disposed on the base 10, and the rotation axis of the worm gear 21 is perpendicular to the base 10. The screw rod 22 is disposed at the telescopic opening 12. The worm gear 21 is sleeved on the screw rod 22 and is in transmission connection with the screw rod 22. One end of the worm 23 is in transmission connection with the worm gear 21, and a bevel gear 231 is fixedly connected to the other end of the worm 23. When the bevel gear 231 rotates, it drives the worm gear 21 to rotate, so that the screw rod 22 passes through the telescopic opening 12 for spiral lifting movement, driving the base 10 to lift.

[0053] In addition, multiple groups of height adjustment devices 20 are provided. The multiple groups of height adjustment devices 20 are arranged at intervals on the base 10, and the bevel gears 231 of the multiple groups of height adjustment devices 20 are engaged. Among them, the worm 23 of at least one group of height adjustment devices 20 extends out of the recess 11.

[0054] It should be noted that multiple height adjustment devices 20 can be provided. The multiple height adjustment devices 20 can be evenly spaced on the base 10 or arranged at uneven intervals on the base 10, and the present application does not limit this.

[0055] It can be understood that when the height of the dishwasher 100 needs to be adjusted, the user can rotate the screw rod 22 extending out of the recess 11. This screw rod 22 can drive other screw rods 22 meshing with it to rotate, causing all the screw rods 22 to rotate simultaneously. Then, the other end of the screw rod 22 drives the worm gear 21 to rotate, and finally drives the screw rod 22 connected to the worm gear 21 to perform a helical lifting and lowering movement. At this time, the worm gear 21 is connected to the base 10 of the dishwasher 100, and the screw rod 22 moves up and down relative to the base 10, thereby lifting and lowering the body and the base 10 of the dishwasher 100. The screw rods 22 of multiple groups of height adjustment devices 20 are connected by bevel gears 231, enabling the user to control the lifting and lowering of all the height adjustment devices 20 simultaneously by controlling one screw rod 22, and the lifted and lowered heights are the same, making each height adjustment device 20 of the dishwasher 100 at the same height, improving the convenience for the user to control the height of the dishwasher 100 and the stability when the dishwasher 100 is placed.

[0056] In a possible structural design, as Figure 3 、 Figure 4 and Figure 5 shown, a first external thread 211 is provided on the outer peripheral wall surface of the worm gear 21, and a first internal thread 212 is provided on the inner peripheral wall surface of the worm gear 21. The screw rod 22 is sleeved on the worm gear 21, and a second external thread 221 meshing with the first internal thread 212 is provided on the outer peripheral wall surface of the screw rod 22. One end of the worm 23 close to the worm gear 21 is provided with a third external thread 232 meshing with the first external thread 211. The worm 23 is in transmission connection with the worm gear 21, so that when the worm 23 rotates, it drives the worm gear 21 to rotate around its rotation center, thereby driving the screw rod 22 to perform a helical lifting and lowering movement.

[0057] In this way, the screw rod 22, the worm gear 21 and the worm 23 are rotationally connected by threads, making the transmission accuracy of the height adjustment device 20 higher, avoiding the situation that multiple groups of height adjustment devices 20 are lifted or lowered by different heights, causing the dishwasher 100 to shake, etc., and improving the stability of the dishwasher 100 during the lifting and lowering process.

[0058] In some embodiments of the present application, as Figure 6 shown, the base 10 further includes: a fixing member 15, which is arranged in the recess 11 and is fixedly connected to the base 10. The fixing member 15 is provided with a lifting hole 151 corresponding to the telescopic opening 12; the worm gear 21 is arranged in the fixing member 15, enabling the worm gear 21 to rotate around its rotation axis, and the screw rod 22 passes through the lifting hole 151.

[0059] Among them, the fixing member 15 can be connected to the bottom plate 13 of the base 10 or can be connected to the side plate 14 of the base 10. The present application does not make any limitations in this regard.

[0060] In this way, the fixing member 15 can enable the worm wheel 21 to rotate around its rotation axis, preventing the worm wheel 21 from displacing during rotation. Passing the screw rod 22 through the lifting hole 151 can also limit the position of the screw rod 22, preventing the screw rod 22 from shifting, which may cause deviation in the height adjustment device 20 and result in inconsistent lifting heights of the dishwasher 100, further improving the stability of the dishwasher 100 during the lifting process.

[0061] In some embodiments of the present application, as Figure 6 and Figure 7 shown, the fixing member 15 includes: a frame body 152, a first limiting plate 153, and a second limiting plate 154. The frame body 152 is fixedly connected to the base 10.

[0062] Among them, the first limiting plate 153 and the first limiting plate 153 are connected to the frame body 152, and a first lifting hole 151 is provided on the first limiting plate 153. The second limiting plate 154, the second limiting plate 154 is connected to the frame body 152, and a second lifting hole 151 is provided on the second limiting plate 154. The first limiting plate 153 and the second limiting plate 154 are spaced apart, and the first lifting hole 151 and the second lifting hole 151 are correspondingly arranged. The worm wheel 21 is arranged between the first limiting plate 153 and the second limiting plate 154 to enable the worm wheel 21 to rotate around its rotation axis, and the screw rod 22 penetrates through the first lifting hole 151 and the second lifting hole 151.

[0063] In this way, the first limiting plate 153 and the second limiting plate 154 can limit the position of the worm wheel 21, preventing the worm wheel 21 from moving along its rotation axis direction, enabling the worm wheel 21 to rotate around its rotation axis. Moreover, the frame body 152 is fixedly connected to the base 10, further fixing the worm wheel 21. The screw rod 22 penetrates through the first lifting hole 151 and the second lifting hole 151, enabling the screw rod 22 to perform a lifting movement relative to the base 10, improving the stability of the dishwasher 100 during the lifting process. Additionally, the internal space enclosed by the frame body 152, the first limiting plate 153, and the second limiting plate 154 can also protect the worm wheel 21 from the influence of the external environment.

[0064] In a possible structural design, a part of the worm 23 extends into the fixing member 15, that is, the part of the worm 23 in transmission connection with the worm wheel 21 is located within the fixing member 15.

[0065] In this way, the fixing member 15 can not only limit the position of the worm wheel 21 to enable the worm wheel 21 to rotate around its rotation center, but also limit the position of the worm 23 to enable the worm 23 to rotate around its rotation center, preventing deviation between the worm wheel 21 and the worm 23. The fixing member 15 can also protect the connection between the worm 23 and the worm wheel 21 from the influence of external foreign objects, further improving the connection stability between the worm wheel 21 and the worm 23.

[0066] In another possible structural design, the worm gear 21 is arranged between the first limiting plate 153 and the second limiting plate 154, and a part of the worm gear 21 protrudes from the housing 152. The part of the worm gear 21 protruding from the housing 152 is rotatably connected to the worm 23.

[0067] In this way, there is no need to extend the worm 23 into the fixing member 15 to connect with the worm gear 21, which improves the convenience of the installation height adjusting device 20.

[0068] In some embodiments of the present application, as Figure 6 and Figure 8 shown, the base 10 further includes: a support cylinder 16. The support cylinder 16 is arranged on the side of the fixing member 15 close to the body. One end of the support cylinder 16 is connected to the fixing member 15, and the other end of the support cylinder 16 is connected to the body. A lifting channel 161 is formed in the support cylinder 16. The lifting channel 161 is communicated with the lifting hole 151. The screw rod 22 is arranged in the lifting channel 161, and the screw rod 22 can perform a spiral lifting movement in the lifting channel 161.

[0069] Among them, the support cylinder 16 can be set as a cylinder, a cube or a frustum of a pyramid, and the present application does not make any limitation thereto.

[0070] In this way, the support cylinder 16 connects the base 10 and the body, preventing the body from shaking during the lifting of the height control assembly. The support cylinder 16 can also protect the screw rod 22 from the influence of the external environment and prevent external foreign objects from affecting the normal operation of the screw rod 22.

[0071] In a possible structural design, the lifting channel 161 in the support cylinder 16 is arranged in cooperation with the screw rod 22, and the inner peripheral wall surface of the support cylinder 16 is provided with a second internal thread, which is engaged with the third external thread 232 on the outer peripheral wall surface of the screw rod 22.

[0072] In this way, when the worm gear 21 drives the screw rod 22 to rotate around its rotation center, the screw rod 22 can perform a spiral lifting movement in the lifting channel 161. The second internal thread can support the screw rod 22, and the second internal thread and the first internal thread 212 can support the screw rod 22 at the same time, increasing the pressure that the screw rod 22 can bear and preventing the screw rod 22 from being unable to perform a spiral lifting movement due to excessive pressure, thus improving the applicability of the height adjusting device 20.

[0073] In some embodiments of the present application, as Figure 9 shown, the height adjusting device 20 further includes: a transmission member. The transmission member is arranged at one end of the screw rod 22 of the height adjusting assembly extending out of the recessed portion 11, and the transmission member is used to transmit power for the rotation of the screw rod 22.

[0074] In this way, the user can control the rotation of the screw rod 22 by controlling the rotating member, thereby controlling the lifting or lowering of the height of the dishwasher 100 by multiple groups of height adjustment devices 20, improving the convenience for the user to adjust the height of the dishwasher 100.

[0075] In a possible structural design, the transmission member can be a grip, and the user can rotate the grip to make the screw rod 22 rotate around its rotation center.

[0076] In this way, the user can rotate the grip to make the screw rod 22 rotate around its rotation center, thereby making the height adjustment assembly move up and down, achieving the purpose of adjusting the height of the dishwasher 100, enabling the user to adjust the height of the dishwasher 100 according to their own needs, and improving the user experience.

[0077] In another possible structural design, the transmission member can be a motor or a motor, etc., and the user can control the motor or the motor to make the screw rod 22 rotate around its rotation center.

[0078] In this way, the user can control the motor or the motor to make the screw rod 22 rotate around its rotation center, thereby controlling the height adjustment of the dishwasher 100, without manually lifting or lowering the height of the dishwasher 100, improving the convenience for the user to lift or lower the height of the dishwasher 100.

[0079] In a possible structural design, as Figure 10 shown, one end of the screw rod 22 extending out of the recessed portion 11 can be set as a hexagonal prism, and the transmission member is arranged in cooperation with the screw rod 22.

[0080] In this way, one end of the screw rod 22 extending out of the recessed portion 11 can be set as a hexagonal prism. Compared with setting one end of the screw rod 22 extending out of the recessed portion 11 as a cylinder, the edges and corners of the hexagonal prism can increase the torsional resistance of the screw rod 22, avoiding the occurrence of sliding at the connection between the rotating member and the screw rod 22 when the torque on the screw rod 22 is too large, thereby affecting the rotation of the screw rod 22 and making the height adjustment device 20 unable to lift or lower the height of the dishwasher 100, improving the stability of the height adjustment device 20.

[0081] In some embodiments of the present application, when the transmission member rotates, the screw rods 22 of multiple groups of height adjustment devices 20 rise or fall synchronously.

[0082] Among them, when the transmission member makes the screw rod 22 rotate in the same direction, multiple groups of height adjustment devices 20 can lift the dishwasher 100 simultaneously or lower the dishwasher 100 simultaneously, and the present application does not make a limitation on this.

[0083] In this way, the screws 22 of multiple groups of height adjustment devices 20 rise or fall synchronously, which can ensure the stability of the dishwasher 100 during the lifting process, prevent the dishwasher 100 from shaking due to inconsistent heights of each group of height adjustment devices 20, and improve the stability of the dishwasher 100 during the lifting process.

[0084] In some embodiments of the present application, for another example Figure 10 As shown, the height adjustment device 20 further includes: a limiting member 24, the limiting member 24 is connected to the base 10, and the limiting member 24 is used to limit the worm 23 so that the worm 23 rotates along its rotation axis.

[0085] Among them, the limiting member 24 can be connected to the bottom plate 13 of the base 10 or the side plate 14 of the base 10, and the present application does not make any limitations in this regard.

[0086] The limiting member 24 can be arranged on one side of the worm 23 or on the circumferential side of the worm 23, that is, the worm 23 passes through the limiting member 24, and the present application does not make any limitations in this regard.

[0087] In this way, the limiting member 24 can make the worm 23 rotate around its rotation axis, prevent the worm 23 from shifting during rotation, resulting in a deviation in the height adjustment device 20 and inconsistent lifting heights of the height adjustment device 20 of the dishwasher 100, and further improve the stability of the dishwasher 100 during the lifting process.

[0088] In a possible structural design, for another example Figure 10 As shown, the limiting member 24 may include a first limiting member 241 and a second limiting member 242. The first limiting member 241 is connected to the bottom plate 13 of the base 10. The first limiting plate 153 is arranged on the side of the worm 23 close to the base 10 and abuts against the side of the worm 23 close to the base 10. The second limiting member 242 is also connected to the bottom plate 13 of the base 10. The second limiting member 242 is partially arranged on the side of the worm 23 away from the base 10 and abuts against the side of the worm 23 away from the base 10.

[0089] In this way, the first limiting member 241 and the second limiting member 242 can limit the worm 23, prevent the worm 23 from shifting during rotation, resulting in a deviation in the height adjustment device 20. The first limiting member 241 and the second limiting member 242 can improve the limiting ability of the limiting member 24, prevent the worm 23 from falling off the limiting member 24, resulting in a deviation in the height adjustment device 20, and improve the stability of the worm 23 during rotation.

[0090] Among them, multiple groups of the first limiting member 241 and the second limiting member 242 can be provided. The first limiting member 241 and the second limiting member 242 can abut against the external thread of the worm 23 or the bevel gear 231 of the worm 23, and the present application does not make any limitations in this regard.

[0091] In some embodiments of the present application, as Figure 11 and Figure 12 shown, the height adjustment device 20 further includes: a foot 25 disposed at one end of the screw 22 away from the body. The foot 25 is connected to the screw 22, and the foot 25 is used to abut against the placement surface of the dishwasher 100.

[0092] As Figure 12 and Figure 13 shown, the base 10 further includes: a placement hole 17 disposed on the side of the base 10 away from the body. The placement hole 17 is correspondingly arranged with the foot 25. The placement hole 17 is used to place the foot 25 and is communicated with the fixing member 15.

[0093] In this way, the foot 25 can support the dishwasher 100, making the placement of the dishwasher 100 more stable, and can also prevent the screw 22 from directly contacting the placement surface, causing damage to the screw 22, thereby affecting the normal operation of the height adjustment device 20. When the height adjustment device 20 is not needed, the foot 25 can be placed in the placement hole 17, so that the dishwasher 100 is stably placed in a cabinet or other positions, preventing the foot 25 from being impacted, and can also make the placement of the dishwasher 100 more stable.

[0094] In some embodiments of the present application, as Figure 14 shown, multiple groups of height adjustment devices 20 are respectively a first height adjustment device 26, a second height adjustment device 27, and a third height adjustment device 28; the three groups of height adjustment devices 20 are arranged at triangular intervals on the base 10, and the first height adjustment device 26 and the second height adjustment device 27 are disposed at the edge of the recess 11. The distance from the third height adjustment device 28 to the first height adjustment device 26 and the second height adjustment device 27 is equal, and the screw 22 of the third height adjustment device 28 extends out of the recess 11.

[0095] It can be understood that arranging the three groups of height adjustment devices 20 at triangular intervals on the base 10 can improve the stability of the body. Setting the distance from the third height adjustment device 28 to the first height adjustment device 26 and the second height adjustment device 27 to be equal can make the pressure transmitted from the body to the height adjustment device 20 more uniform, preventing damage or breakage of one of the height adjustment devices 20 due to excessive force on it, and ensuring that the lifting height of the dishwasher 100 body is inconsistent and causing shaking, thus improving the stability of the dishwasher 100 body.

[0096] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
