[0002] In order to improve the utilization rate of the cleaning chamber in a dishwasher or other cleaning device, the spray arm in the cleaning device will use a linear motion to spray washing water to various areas of the cleaning chamber. The existing spray arm generally has only one, and it reciprocates along the length or width direction of the cleaning chamber during the movement process.

[0003] The movement of a single spray arm causes the center of gravity of the cleaning equipment to change continuously, which is not conducive to the stable placement of the cleaning equipment. The shaking of the cleaning equipment can easily generate noise or the cleaning equipment may shift or even fall from a height and cause damage. At the same time, during the movement of the spray arm, when the washing water sprayed from the spray hole of the spray arm acts on the objects and cleans them, the force points of the objects change continuously, and it is difficult to maintain balance, so the objects are prone to shaking, generating noise or even damage.

[0004] Therefore, it is urgent to develop a cleaning machine so that the cleaning machine can be placed stably and the objects can be evenly stressed during the cleaning process, thereby reducing the probability of the cleaning machine or the objects generating noise or even being damaged.

The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] like Figures 1 to 6 As shown, this embodiment provides a cleaning machine to improve the movement process of the spray arm 200, the stability of the cleaning machine, and the force balance of the washed items, so as to avoid the cleaning machine or the items from shaking and causing noise or even damage. The cleaning machine can clean fruits, vegetables and other foods, and can also clean tableware such as bowls and chopsticks.

[0040] The cleaning machine comprises a housing 100, a driving mechanism 300 and two spray arms 200. The housing 100 has a cleaning chamber; the two spray arms 200 are both arranged in the cleaning chamber and extend along a first direction X, and the two can approach or move away from each other in a second direction Y that is an angle with the first direction X, and each spray arm 200 is provided with at least two spray holes 210; the power output end of the driving mechanism 300 has two staggered movable parts 310, and the two movable parts 310 can move toward or away from each other in the second direction Y, and the two spray arms 200 are assembled on the corresponding movable parts 310.

[0041] During the movement of the two spray arms 200 in the above arrangement, the washing water sprayed from the spray holes 210 can cover the entire spray chamber; the two moving parts 310 of the driving structure respectively drive the corresponding two spray arms 200, and can move toward or away from each other, so that during the movement of the spray arms 200, the center of gravity of the cleaning machine remains unchanged, avoiding the shaking of the cleaning machine due to the change of the center of gravity, which is conducive to the stable and safe placement of the cleaning machine; at the same time, the spray arms 200 follow the moving parts 310 to move toward or away from each other, and when the water flow sprayed by each spray arm 200 acts on the object, the impact force generated on the object is symmetrical about the center of the object, ensuring that the force of the object is balanced, which is conducive to ensuring the stable placement of the object and reducing the probability of shaking, noise or even damage of the object due to uneven force. It should be noted that when in use, the object needs to be placed in the middle area of ​​the cleaning chamber, and in the state of being located between the two spray arms 200 along the second direction Y, the force balance of the object can be achieved to the maximum extent.

[0042] Combination Figures 2 to 4As shown, in order to simplify the driving structure, the two moving members 310 are both strip-shaped and extend along the second direction Y, and are arranged at intervals in the first direction X. The driving mechanism 300 has a transmission member 320 located between the two moving members 310. The transmission member 320 is disc-shaped and its peripheral wall is in contact with the outer walls of the two moving members 310 at the same time. The transmission member 320 is arranged to be able to rotate forward or reversely about its own axis, so that the two moving members 310 move toward or away from each other. The above arrangement only requires one transmission member 320 to simultaneously drive the two moving members 310 to move relative to or away from each other, reducing the transmission cost; at the same time, the transmission member 320 is in direct contact with the moving member 310, and is converted into the linear motion of the moving member 310 through its own circumferential motion, reducing the intermediate transmission structure and improving the energy transmission efficiency; finally, the transmission member 320 is disc-shaped, and its rotation process will not affect the center of gravity of the cleaning machine, which is conducive to ensuring the stable placement of the cleaning machine.

[0043] In order to reduce the influence of the moving part 310 on the center of gravity of the cleaning machine during its movement, the transmission part 320 is located in the middle area of ​​the cleaning chamber, and the two moving parts 310 are arranged symmetrically about the axis of the transmission part 320 in any state during the movement. When moving, the centers of gravity of the two moving parts 310 are respectively away from the transmission part 320 along the second direction Y, so that the center of gravity of the cleaning machine will not change in the first direction X and the second direction Y, which is conducive to ensuring the stable placement of the cleaning machine.

[0044] The transmission member 320 is a gear, and the mobile member 310 is a rack. The gear is arranged adjacent to the two racks and meshes with the teeth of the two racks respectively. Through the meshing transmission of the gear and the rack, the transmission accuracy can be effectively guaranteed, thereby accurately controlling the position of the mobile member 310. In another exemplary embodiment, the transmission member 320 is a roller, and the peripheral wall of the roller and the mobile member 310 directly roll together. In order to improve the reliability of the transmission, the outer peripheral sleeve of the roller is provided with a rubber sleeve to increase the friction between the roller and the mobile member 310, thereby realizing the effective transmission of power.

[0045] The top of the rack is provided with a connecting seat 311, the spray arm 200 is arranged on the connecting seat 311, the teeth of the rack are arranged on the side wall adjacent to the connecting seat 311, and the gear is correspondingly located between the moving paths of the two racks, so that even if the cleaning residue falls onto the teeth of the rack, it will slide down and will not remain on the rack, thereby ensuring the cleanliness of the meshing part when the gear and the rack are meshed, which is beneficial to the stability of the rack transmission.

[0046] To facilitate the installation of the moving member 310, the cleaning machine further includes two guide members 400, both of which are arranged in the cleaning chamber and extend along the first direction X. The guide member 400 has a guide channel 410 arranged along its length direction. The two moving members 310 are respectively movably constrained in the two corresponding guide channels 410 to extend out of the guide channels 410 or hide in the guide channels 410. This arrangement enables the moving member 310 to be moved and hidden inside the guide channel 410 after cleaning is completed or before cleaning begins, thereby preventing the user from touching the moving member 310 when taking or placing items, ensuring the matching accuracy between the moving member 310 and the guide member 400, and reducing the risk of abnormal noise or jamming due to poor matching accuracy between the moving member 310 and the guide member 400.

[0047] Because the moving member 310 is slidably arranged in the guide channel 410, in order to reduce the sliding fit area, the outer periphery of the moving member 310 is convexly provided with an annular first support portion 312, and the moving member 310 is slidably matched with the guide member 400 through the first support portion 312. Wherein, along the moving direction of the moving member 310, the length of the first support portion 312 is much smaller than the length of the moving member 310. This arrangement makes the processing of the first support portion 312 more convenient and reduces the processing cost. The length of the first support portion 312 is much smaller than the length of the moving member 310, and it can be understood that the length of the first support portion 312 is less than one tenth or even one hundredth of the length of the moving member 310.

[0048] Combination Figure 4 and Figure 5 As shown, in order to improve the stability of the support for the moving member 310, a second support portion is provided in the cleaning chamber, and the second support portion and the first support portion 312 are arranged at intervals along the moving direction of the moving member 310, and the second support portion is used to support the portion of the moving member 310 located outside the guide member 400. When the moving member 310 is hidden in the guide groove, the two ends of the moving member 310 are supported by the first support portion 312 and the second support portion respectively, which is conducive to the stable placement of the moving member 310. Among them, the first support portion 312 always follows the reciprocating movement of the moving member 310, thereby ensuring that the moving member 310 slides and cooperates with the first support portion 312 with a smaller area and the guide member 400, and the second support portion is fixed relative to the cleaning chamber to avoid following the movement of the moving member 310 and reduce energy consumption.

[0049] The cleaning machine includes a base 500, which extends upward from the bottom to form a support wall 510, and the support wall 510 includes a support surface 511, and the support surface 511 forms a second support portion. Two support walls 510 are provided, and the support wall 510 includes a limiting surface 512 set at an angle with the support surface 511. The two limiting surfaces 512 are respectively located on the outer sides of the two moving parts 310 to limit the two moving parts 310 from moving away along the first direction X.

[0050] The moving part 310 has a flow channel 313 for fluid flow inside, the water outlet 314 of the flow channel 313 is connected to the guide channel 410, and the water outlet of the flow channel 313 is connected to the spray hole 210 of the spray arm 200. This arrangement enables the moving part 310 to achieve water channel communication while driving the spray arm 200 to move, which is conducive to simplifying the water channel structure, and there is no need to set a hose structure, thereby avoiding the possibility of cracks in the hose or water leakage at the interface during the movement of the moving part 310.

[0051] Combination Figure 6 As shown, the side wall of the guide member 400 is provided with a water inlet 411 connected to the guide channel 410, and the water inlet 411 is arranged on the moving path of the moving member 310. Under the action of its own movement, the moving member 310 can move to cover the water inlet 411 or release the cover of the water inlet 411. When the water inlet 411 is covered, the water flow cannot enter the guide channel 410, and thus cannot enter the cleaning chamber, so that after cleaning is completed, residual water is prevented from entering the cleaning chamber to generate odor.

[0052] The moving member 310 is tubular, and when the moving member 310 moves to cover the water inlet 411, the outer wall of the moving member 310 forms a surface seal with the periphery of the water inlet 411. The above structure is simple and easy to assemble; and it avoids setting up a separate valve body structure, reducing costs.

[0053] The guide member 400 is provided with a blocking portion 412. Under the action of its own movement, the moving member 310 can move to the point where the water flow outlet 314 is covered by the blocking portion 412 or moves away from the blocking portion 412. When the water flow outlet 314 is covered by the blocking portion 412, the residual water cannot enter the cleaning cavity and produce odor. When the water flow outlet 314 is away from the blocking portion 412, the water flow can enter the cleaning cavity to clean the items.

[0054] To avoid water leakage, a sealing member 330 is provided in the annular gap between the moving member 310 and the guide member 400. The sealing member 330 is fixed on the moving member 310 and moves synchronously with the moving member 310.

[0055] The two moving parts 310 are both provided with a connection seat 311, and the two spray arms 200 are respectively arranged on the corresponding connection seats 311. The movement process of the two moving parts 310 drives the two connection seats 311 to move from the middle area of ​​the cleaning chamber to the two ends of the cleaning chamber along the second direction Y respectively. In the two spray arms 200, at least one spray hole 210 on each is inclined toward the other spray arm 200, so that the moving ranges of the two spray arms 200 do not overlap, and the spray ranges of the washing water sprayed from the corresponding spray holes 210 at least partially overlap. This arrangement can avoid the two spray arms 200 from interfering with each other, and realize the comprehensive coverage of the cleaning chamber by the spray range. Exemplarily, the number of spray holes 210 on each spray arm 200 is set to a plurality of, and the outlets of some spray holes 210 on each spray arm 200 face the other spray arm 200, and the outlets of another part of the spray holes 210 on each spray arm 200 are away from the other spray arm 200. In another exemplary embodiment, the spray hole 210 of the spray arm 200 is provided with a flow divider in the middle, similar to the nozzle of a sprayer, and the water flow is dispersed in an inverted cone shape after being sprayed out from the spray hole 210 to achieve full coverage of the cleaning chamber. The specific structure of the spray hole 210 can be implemented using existing technology and is not specifically limited here.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
