Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a washing machine used for washing tableware, fruits and vegetables. Background Art

[0002] The sink-type cleaning machine uses a sink to define a washing chamber and adopts an upward-flipping door structure.

[0003] For example, the applicant's prior patent ZL 202321042974.7, "A Sink-Type Washing Machine," discloses a structure comprising a sink with a receiving chamber and an open top communicating with the chamber; a spray arm disposed within the sink's receiving chamber and communicating with a first water supply channel; and a door disposed on the top of the sink. This structure is common in sink-type washing machines.

[0004] Sink-style washers are generally small in size and typically feature a dish basket positioned near the bottom of the wash chamber. A spray arm, positioned at the base of the basket, sprays upward, rinsing the dishes within. When a large number of dishes are placed in the basket, the spray arm sprays water upward, with a relatively fixed spray direction and limited coverage. This can block the water flow from dishes at the top of the basket or on the top surface of the dishes, creating blind spots and making thorough cleaning difficult. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which can expand the spraying area, thereby eliminating cleaning dead angles and improving the cleaning effect in view of the current status of the existing technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A cleaning machine includes a box body, a spray arm and a water pumping mechanism. The spray arm is arranged in the box body and close to the bottom of the box body. The water pumping mechanism is arranged at the bottom of the box body and is used to pump water into the spray arm. The box body is also provided with an inner water pipe extending from bottom to top close to the inner wall of the box body. The lower end of the inner water pipe is connected to the water pumping mechanism. The upper end of the inner water pipe is detachably connected to a spray part that can spray toward the upper middle part of the box body. The spray part is formed with a swinging structure that can swing in all directions as it sprays water.

[0008] The spray arm of the utility model sprays from bottom to top, and mainly sprays the tableware above the spray arm. When there are many dishes to be washed, the spray part sprays the top and sides of the tableware. As the spray part sprays, the sprayed water column sprays in all directions under the action of the swing structure, further expanding the spray range of the spray part in the upper middle part of the washing chamber, which is conducive to eliminating cleaning dead corners and improving the cleaning effect.

[0009] Preferably, the inner water pipe is provided with a water guide section extending obliquely upward toward the washing chamber, and the spray element is detachably connected to the upper end of the water guide section. With this structure, the obliquely upward water guide section serves as a transition, thereby preventing the spray element from interfering with the inner wall of the washing chamber during its swing.

[0010] Preferably, the spray element comprises a hose and a nozzle sealed at the upper end of the hose. The lower end of the hose is detachably mounted on the outer periphery of the water guide section to form the swing structure. This structure enables the spray element to swing in all directions with the spraying water column, thereby expanding the spray range and eliminating blind spots in the cleaning process.

[0011] Preferably, the outer wall of the water-conducting section is embedded with a circumferentially arranged sealing ring. When the lower end of the hose is positioned over the outer periphery of the water-conducting section, the inner wall of the hose and the sealing ring are squeezed and sealed. The spray element is detachably mounted on the water-conducting section, facilitating the independent production and subsequent assembly of the components and facilitating subsequent disassembly and maintenance. This structure improves the sealing performance of the connection.

[0012] Preferably, the nozzle is provided with a plurality of axially penetrating spray holes, and the outer periphery of the nozzle is further provided with at least two radially extending swing balance pieces. Such a structure is conducive to expanding the spray range and eliminating blind spots in cleaning.

[0013] As a structural optimization, the water guide section is equipped with a one-way valve to control its connection. This one-way valve is linked to the spray element. When the spray element is connected to the water guide section, the one-way valve connects the water guide section and the spray element. When the spray element is disconnected from the water guide section, the one-way valve isolates the water guide section. With this structure, when the dishware to be cleaned is small, the spray element can be eliminated, and only the bottom spray arm can be used for concentrated spraying to achieve effective cleaning.

[0014] Preferably, the water guide section and the inner water pipe are separate structures, and the water guide section is detachably connected to the inner water pipe via a connecting assembly. The above structure facilitates the independent production and subsequent assembly of each component.

[0015] Preferably, the front sidewall of the inner water pipe is provided with a water inlet corresponding to the water inlet of the water guide section. The edge of the water inlet of the water guide section extends outward to form a cover plate that can cover the front sidewall of the inner water pipe. The rear sidewall of the inner water pipe is provided with an assembly plate. The side edge of the assembly plate extends forward to form a connecting arm that can be locked with the cover plate. The assembly plate and the cover plate together constitute the connection assembly. Preferably, the transverse width of the cover plate is greater than the transverse width of the inner water pipe. The front end of the connecting arm forms a clip. Correspondingly, the cover plate is provided with a clip into which the clip is inserted. The above structure facilitates the disassembly and assembly of the various components.

[0016] Preferably, the mounting plate is positioned near the inner wall of the enclosure, with a connection hole defined on its back. A locking member extends through the enclosure sidewall and connects to the hole, thereby securing the mounting plate and inner water pipe to the enclosure sidewall. The connection hole can be a threaded hole, and the locking member can be a screw. A metal gasket can be placed between the mounting plate and the enclosure inner wall. This structure improves the reliability of the inner water pipe's installation within the enclosure and provides effective support for the showerhead during directional swinging.

[0017] Compared with the prior art, the advantages of the present invention are: the spray arm of the present invention sprays from bottom to top, and mainly sprays the tableware above the spray arm. When there are more tableware to be washed, the spray part sprays the top and sides of the tableware, and as the spray part sprays, the sprayed water column sprays in all directions under the action of the swing structure, further expanding the spray range of the spray part in the upper middle part of the washing chamber, which is conducive to eliminating cleaning dead corners and improving the cleaning effect.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, the washing machine of this embodiment includes a housing 1, a spray arm 2, and a water pumping mechanism 3. The bottom of the housing 1 is provided with a concave water return area 11, and the top of the water return area 11 is covered with a filter plate. The spray arm 2 is provided in the housing 1 and is located above the water return area 11 and close to the filter plate. The water pumping mechanism 3 is provided in the water return area 11 at the bottom of the housing 1 and is used to pump water in the water return area 11 into the spray arm 2. The housing 1 is provided with a bowl basket 7 located above the spray arm 2, and the bowl basket 7 is used to place tableware.

[0025] In this embodiment, the housing 1 is further provided with an inner water pipe 4 extending upward from the inner sidewall of the housing 1. The lower end of the inner water pipe 4 is connected to the water pump mechanism 3. The upper end of the inner water pipe 4 is detachably connected to a spray element 5 that sprays water toward the upper middle portion of the housing 1. The spray element 5 has a swinging structure that swings in all directions as it sprays water. The spray element 5 is located above the bowl basket 7.

[0026] Specifically, the side of the inner water pipe 4 is provided with a water guide section 41 that extends obliquely upward toward the washing chamber. The spray element 5 is detachably connected to the upper end of the water guide section 41. With this structure, the obliquely upward water guide section 41 acts as a transition, preventing the spray element 5 from interfering with the inner wall of the housing 1 during its swing.

[0027] The spray element 5 of this embodiment comprises a hose 51 and a nozzle 52 sealed at the upper end of the hose 51. The lower end of the hose 51 is removably mounted on the outer periphery of the water guide 41, forming the aforementioned swinging structure. This structure enables the spray element 5 to swing in all directions with the spraying water column, thereby expanding the spraying range and eliminating blind spots in the cleaning process.

[0028] The outer wall of the water-conducting section 41 is embedded with a circumferentially arranged sealing ring 42. When the lower end of the hose 51 is positioned around the outer periphery of the water-conducting section 41, the inner wall of the hose 51 and the sealing ring 42 are squeezed and sealed. The detachable attachment of the spray element 5 to the water-conducting section 41 facilitates the assembly of the components after independent production and facilitates later disassembly and maintenance. This structure also improves the sealing performance of the joints.

[0029] The nozzle 52 is provided with a plurality of axially extending spray holes 521, and the outer periphery of the nozzle 52 is also provided with at least two (four in this embodiment) radially extending swing balance pieces 522. Such a structure is advantageous in expanding the spraying range and eliminating blind spots in cleaning.

[0030] In this embodiment, the water guide section 41 and the inner water pipe 4 are separate structures, and the water guide section 41 is detachably connected to the inner water pipe 4 through the connecting assembly 6. The above structure facilitates the independent production and subsequent assembly of each component.

[0031] Specifically, the front sidewall of the inner water pipe 4 is provided with a water inlet 43 corresponding to the water inlet 411 of the water guide section 41. The edge of the water inlet 411 of the water guide section 41 extends outward to form a cover plate 61 that covers the front sidewall of the inner water pipe 4. The rear sidewall of the inner water pipe 4 is provided with an assembly plate 62. The side edges of this assembly plate 62 extend forward to form connecting arms 621 that can be locked and connected to the cover plate 61. The assembly plate 62 and the cover plate 61 together constitute the connection assembly 6. The transverse width of the cover plate 61 is greater than the transverse width of the inner water pipe 4. The front ends of the connecting arms 621 form a locking foot 622. Correspondingly, the cover plate 61 is provided with a locking slot 611 into which the locking foot 622 is inserted. This structure facilitates the disassembly and assembly of the various components.

[0032] The mounting plate 62 is positioned near the inner wall of the housing 1. A connection hole 623 is defined on the back of the mounting plate 62. A locking member passes through the side wall of the housing 1 and connects to this connection hole 623, thereby securing the mounting plate 62 and the inner water pipe 4 to the side wall of the housing 1. The connection hole 623 can be a threaded hole, and the locking member can be a screw. A metal gasket 63 can be placed between the mounting plate 62 and the inner wall of the housing 1. This structure improves the reliability of the inner water pipe 4 within the housing 1 and provides effective support for the spray element 5 during its directional swinging.

[0033] The spray arm 2 of this embodiment sprays from bottom to top, and performs the main spray on the tableware above the spray arm 2. When there are more tableware to be washed, the spray part 5 sprays the top and sides of the tableware. As the spray part 5 sprays, the sprayed water column sprays in all directions under the action of the swing structure, further expanding the spray range of the spray part 5 in the upper middle part of the washing chamber, which is conducive to eliminating cleaning dead corners and improving the cleaning effect.

[0034] Example 2:

[0035] In this embodiment, a one-way valve is installed in the water guide 41 to control its connection. This one-way valve is linked to the spray element 5. When the spray element 5 is connected to the water guide 41, the one-way valve connects the water guide 41 and the spray element 5. When the spray element 5 is disconnected from the water guide 41, the one-way valve isolates the water guide 41. This structure allows the spray element 5 to be eliminated when the dishware to be cleaned is small, and effective cleaning can be achieved by focusing the spray solely on the bottom spray arm 2.
