Description

Technical Field

[0001] This invention belongs to the field of household appliances, and specifically relates to a cleaning machine. Background Technology

[0002] A washing machine is a device that sprays cold or hot water onto dishes to remove dirt and grime adhering to them or cleaning fruits and vegetables. Existing spray-type washing machines generally achieve spraying in all directions through the rotation of sprayers.

[0003] Current cleaning machines, such as the Chinese utility model patent "A Cleaning Machine with Drying Function" filed earlier by the applicant, patent number ZL202022220994.1 (authorization announcement number CN213993488U), disclose a cleaning machine with drying function, including a housing, a spray arm, an impeller assembly and a drive component. The power output shaft of the drive component is arranged vertically and its upper end passes through the top wall of the spray arm to form a rotating connection part. A fan impeller is connected to the rotating connection part by a one-way bearing. The fan impeller can be disengaged from the power output shaft when the power output shaft rotates forward and can be reversed when the power output shaft rotates in reverse, thereby conveying the air at the bottom of the washing chamber upward.

[0004] Currently, the cleaning method using a single vertical spray from bottom to top results in insufficient cleaning capacity. In addition, while the spray arm reverses to deliver air upwards from the washing chamber, the hot air distribution is uneven, limiting the drying effect on the kitchen utensils above. Furthermore, the heating plate is usually installed at the bottom of the cabinet, but due to the limited space at the bottom of the cabinet, the improvement in heating efficiency and space utilization are limited.

[0005] Therefore, further improvements are needed to the existing cleaning machines. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a cleaning machine that achieves full coverage and rapid drying by using top and bottom convection drying during the drying process, in light of the current state of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a cleaning machine that uses the same water inlet channel to facilitate water supply to the top and / or bottom, in view of the current status of the prior art.

[0008] The third technical problem to be solved by the present invention is to provide a cleaning machine that achieves vertical and horizontal spray cleaning of the objects to be cleaned in the washing chamber, in light of the existing technology described above.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a cleaning machine, comprising:

[0010] The cleaning tank has a washing chamber inside.

[0011] The first spraying component is rotatably disposed in the washing chamber near the bottom. It has a cavity inside, and an inlet communicating with the cavity is opened on its bottom. The wall panel of the first spraying component has a first spray hole communicating with the cavity to spray upward.

[0012] The second spray element is disposed on the top of the washing chamber and has a flow channel inside. The second spray element has a second spray hole that communicates with the flow channel to spray downward.

[0013] Its characteristic is that the cleaning machine further includes:

[0014] The air inlet is in fluid communication with the flow channel of the second spray element to allow drying gas to pass through;

[0015] The fan has an air inlet connected to the air inlet hole and an air outlet connected to the flow channel of the second spray element.

[0016] The guide channel has a first end connected to the inlet end of the flow channel in the second spray element, and a second end arranged adjacent to the inlet of the first spray element, at least for guiding gas into the first spray element.

[0017] In order to automatically switch between washing and drying modes, the washing tank is provided with a water inlet channel, which is arranged adjacent to the flow guide channel. It also includes a switching structure for selectively realizing a first state in which the water inlet channel and the flow channel of the second spray member are connected or a second state in which the flow guide channel and the flow channel are connected.

[0018] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: the switching structure is also used to realize the third state in which the water inlet channel and the flow guide channel are connected.

[0019] The switching structure can be in the form of a three-way valve or other forms, but preferably, the first end of the flow guiding channel, the outlet end of the inlet channel, and the inlet end of the flow channel intersect. The switching structure includes...

[0020] A rotary valve is rotatably disposed at the first end of the flow guide channel, the outlet end of the inlet channel, and the confluence of the flow channel. The outer peripheral wall of the rotary valve has three flow channels arranged circumferentially at intervals. The three flow channels intersect inside the rotary valve and are connected at the intersection.

[0021] A drive component, whose power output end is connected to the rotary valve, drives the rotary valve to rotate, selectively achieving a first state, a second state, or a third state through the corresponding flow channel. This automatically switches between downward washing and / or upward washing or drying modes.

[0022] In order to pump water and / or gas to the first spray element and finally spray it out through the first spray hole, the bottom of the cleaning tank is provided with a power assembly for guiding water and / or gas into the inlet of the first spray element. The power assembly includes a first motor and a first impeller. The first impeller passes through the inlet of the first spray element and is located in the flow channel of the first spray element. The first motor is located below the first impeller, and the first impeller is mounted on the output shaft of the first motor.

[0023] The second spray element can be installed on the door or be part of the door. Preferably, the cleaning box includes a box with an open top and a door covering the open top of the box. The second spray element is a portion of the door. The flow channel includes an inlet channel and a connecting channel connected to the inlet channel. The air outlet of the fan is in fluid communication with the inlet channel. The inlet channel is located above the connecting channel. The top wall of the connecting channel has a connecting port near its center, connecting to the outlet of the inlet channel. Multiple baffles are arranged radially around the connecting port within the connecting channel. A branch channel is formed between adjacent baffles, and each branch channel has at least one second spray hole. Thus, the drying gas from the fan is sprayed out through the second spray holes via the branch channels of the inlet channel and the connecting channel. The presence of the baffles reduces eddies within the connecting channel.

[0024] In order to better guide the fluid from the inlet channel into the connecting channel, a third impeller that can rotate under the impact of the fluid is provided in the connecting port, and the rotation axis of the third impeller is arranged vertically.

[0025] To reduce eddies in the fluid within the inlet channel, a plurality of flow divider plates extending along the length of the inlet channel are provided. The inlet channel is divided into multiple sub-channels by the flow divider plates. An air guide pipe is installed at the outlet of the fan. The air guide pipe partially extends into the inlet channel, and at least one air outlet connected to the corresponding sub-channel is provided on the side wall of the air guide pipe at the position corresponding to each sub-channel.

[0026] To better achieve partial reverse flow of drying gas, the bottom wall of the sub-channel has a locally downward recessed area at the position corresponding to the air guide pipe.

[0027] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: a side spraying component is provided on the inner wall of the cleaning tank, and a draining chamber is located below the washing chamber inside the cleaning tank. The side spraying component is connected to the draining chamber through a water guiding channel.

[0028] The side spray unit can have various structural forms, including a straight spray arm, a three- or four-bladed spray arm, or other forms. Preferably, the side spray unit includes a mounting shaft and spray channels located around the periphery of the mounting shaft. The spray channels are connected to the water guiding channel. The hollow interior of the mounting shaft forms an exhaust channel for venting gas from the washing chamber. This not only achieves horizontal washing of dishes and other items but also allows for the venting of gas from the washing chamber, maintaining gas balance, without the need for a separate exhaust channel.

[0029] There are various forms of spray channel formation, including annular and radial shapes. However, preferably, the outer peripheral wall of the mounting shaft is provided with multiple annular plates arranged at intervals along its axial direction. Along the gas flow direction in the exhaust channel, the outer periphery of each annular plate gradually expands outward. Between two adjacent annular plates, multiple guide ribs are arranged radially around the mounting shaft, and the spray channel is formed between two adjacent guide ribs.

[0030] To better connect the water guiding channel and the spray channel, a plurality of convex strips are provided on the outer peripheral wall of the mounting shaft, which are arranged circumferentially and extend along the axial direction of the mounting shaft. The annular piece is installed on the outer wall of the convex strips, and a water passage is formed between two adjacent convex strips to connect the water guiding channel and the corresponding spray channel.

[0031] To achieve the ability to wash dishes horizontally, there are two side sprayers arranged side by side with intervals. The water guiding channel includes a connecting channel connected to the two side sprayers. The connecting channel is connected to the two water passages. It also includes a second impeller for quickly guiding water into the connecting channel. The second impeller is rotatably disposed near the middle of the connecting channel and is located between the two side sprayers.

[0032] To heat the water or airflow within the guide channel, the guide channel has a portion surrounding the side spray element, a portion of which is a heating section for heating its inner cavity. This allows for preheating of the water flow during the water intake process, reducing the required heating area of ​​the existing bottom heating plate, improving the efficiency of the heating plate during the main wash, and increasing the space utilization of other bottom components due to the smaller heating plate area. Furthermore, the passing airflow can be further heated, improving drying efficiency.

[0033] Preferably, there are two guide sections, which are located on the periphery of the side spray members on the corresponding sides. The guide channel also includes a connecting section that is connected to each of the guide sections. The connecting section is located below the guide section and is connected to the draining cavity.

[0034] Compared with existing technologies, the advantages of this invention are as follows: In this washing machine, part of the drying airflow entering through the air inlet goes to the second spray element at the top and is sprayed downwards, while the other part flows through the guide channel to the first spray element at the bottom and is sprayed upwards. This achieves cross-convection drying of dishes and other items within the washing chamber, improving the drying effect. Simultaneously, the drying airflow entering the bottom heats and dries the bottom area, keeping it dry and preventing dampness and bacterial growth that could contaminate the tableware.

[0050] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] like Figures 1 to 15 As shown, the cleaning machine in this embodiment is used to clean kitchen utensils or fruits and vegetables. The cleaning machine includes a cleaning tank 1, a first spray component 2, a second spray component 3, a fan 4, a guide channel 5, a switching structure 6, and a side spray component 7.

[0052] like Figures 1 to 6 As shown, the washing box 1 includes a box body 11 with an open top and a door 12 covering the open top of the box body 11. The box body 11 and the door 12 enclose a washing chamber 100 and a draining chamber 101 located below the washing chamber 100. The draining chamber 101 and the washing chamber 100 are separated by a drain plate disposed inside the box body. In this embodiment, the rear side of the door 12 is rotatably disposed on the corresponding side of the box body 11. Alternatively, the door can be rotatably disposed on the left or right side of the box body on the corresponding side. A non-rotating form can also be used, as long as the door can be opened or closed over the open top of the box body 11.

[0053] like Figure 3 , Figure 5 and Figure 9As shown, the first spray element 2 is rotatably disposed within the washing chamber 100 near the bottom and is a straight spray arm. Alternatively, a three-bladed spray arm or other types of spray arms can be used. The aforementioned first spray element 2 has a cavity 21 inside. An inlet 211 communicating with the cavity 21 is provided on the bottom wall plate of the first spray element 2, and a first spray hole 212 communicating with the cavity 21 for upward spraying is provided on the top wall plate of the first spray element 2. In addition, to guide water and / or gas into the inlet 211 of the first spray element 2, a power assembly 14 for guiding water and / or gas into the inlet 211 of the first spray element 2 is provided at the bottom of the cleaning tank 1. The power assembly 14 includes a first motor 141 and a first impeller 142. The first impeller 142 passes through the inlet 211 of the first spray element 2 and is located in the flow channel 31 of the first spray element 2. The first motor 141 is located below the first impeller 142. The first impeller 142 is mounted on the output shaft of the first motor 141 and rotates under the drive of the first motor 141. The output shaft of the first motor 141 extends vertically. The structure of the first impeller adopts the impeller structure in the applicant's previous cleaning machine, and will not be described in detail in this embodiment.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, the second spray element 3 is disposed on the top of the washing chamber 100 and is a part of the door 12. Specifically, the door 12 includes a door panel 121 arranged sequentially from top to bottom and the second spray element 3. The second spray element 3 covers the top opening of the housing 11 and can open or close the aforementioned top opening. The aforementioned second spray element 3 has a flow channel 31 inside, and the aforementioned second spray element 3 includes a spray body with a connecting channel 312 inside. An inlet channel 311 is provided above the spray body and is connected to the connecting channel 312. The aforementioned flow channel 31 includes the connecting channel 312 and the inlet channel 311. The fan 4 is located above the spray body 3, and the air outlet of the fan 4 is in fluid communication with the inlet channel 311. The inlet channel 311 is located above the connecting channel 312. Along the airflow path, the connecting channel 312 is located downstream of the inlet channel 311. The aforementioned fan 4 is used to introduce drying gas into the connecting channel 312. The top wall of the connecting channel 312 has a connecting opening 313 near the center, which is connected to the outlet of the inlet channel 311.

[0055] like Figure 7 and Figure 8As shown, the aforementioned inlet channel 311 is provided with multiple diversion grids 3111 extending along its length. In this embodiment, there are four diversion grids 3111; alternatively, three or more can be used. The inlet channel 311 is divided by the aforementioned diversion grids 3111 to form multiple sub-channels 3112. The fan 4 is located between the door panel 121 and the spray body. Integrating the fan 4 into the door body avoids the problem of existing fans being integrated into the cabinet and drawing in old air from below the countertop, thus ensuring the cleanliness of the drawn-in air and facilitating the long-term preservation of tableware inside the cabinet. Figure 6 As shown, multiple air inlets 120 are provided on the side wall of the door 12, and they are spaced apart along the length of the side wall of the door 12. The air inlet of the fan 4 is connected to the air inlet 120, and the air outlet of the fan 4 is fluidly connected to the inlet channel 311 of the flow channel 31 of the second spray element 3, thereby supplying drying gas into the flow channel 31 through the aforementioned air inlets 120. There are various ways to connect the fan 4 and the inlet channel 311. It can be directly connected to the inlet channel, or other methods can be used. In this embodiment, such as... Figure 7 and Figure 8 As shown, an air guide pipe 41 is installed at the air outlet of the fan 4. The air guide pipe 41 partially extends into the inlet channel 311, and at least one air passage 411 communicating with the corresponding sub-channel 3112 is opened on the side wall of the air guide pipe 41 at the position corresponding to each sub-channel 3112. The bottom wall of the sub-channel 3112 has a partially downward recessed area 3113 at the position corresponding to the air guide pipe 41. In this embodiment, there is one air passage 411; in addition, two, three, or more can be used. Figure 10 As shown, the aforementioned connecting channel 312 is provided with multiple baffles 314 arranged radially around the connecting port 313. A diversion channel 315 is formed between two adjacent baffles 314, and the top wall of the diversion channel 315 gradually slopes downward away from the connecting port 313. The bottom wall of the second spray member 3 has multiple second spray holes 3151 at the position corresponding to each diversion channel 315, which are connected to their respective diversion channels 315. The second spray holes 3151 spray downward. In addition, in order to facilitate the flow of fluid into the diversion channel, a third impeller 32 that can rotate under the impact of the fluid is provided in the connecting port 313. The aforementioned third impeller 32 is a centrifugal impeller, the rotation axis of the third impeller 32 is arranged vertically, and the thickness of the blades of the third impeller 32 near its rotation axis is greater than the thickness away from its rotation axis. Thus, due to the different thicknesses on both sides of the blades on the third impeller 32, a circumferential force is generated when water is sprayed onto the third impeller 32, which pushes the third impeller 32 to rotate while being thrown into each branch channel 315.

[0056] like Figure 9As shown, the flow channel 5 is arranged vertically and located on the outer wall of the box. The first end (upper end) of the flow channel 5 is connected to the inlet end of the flow channel 31 inside the second spray element 3. The second end (lower end) of the flow channel 5 is arranged near the inlet 211 of the first spray element 2. The cleaning box 1 is provided with a water inlet channel 13, which is arranged near the flow channel 5. Figure 2 and Figure 5 As shown, the switching structure 6 is used to selectively achieve a first state where the water inlet channel 13 and the flow channel 31 of the second spray element 3 are connected, or a second state where the guide channel 5 is connected to the flow channel 31, or a third state where the water inlet channel 13 and the guide channel 5 are connected. The first end of the guide channel 5, the outlet end of the water inlet channel 13, and the inlet end of the flow channel 31 intersect. Figure 5 , Figure 13 and Figure 14As shown, the switching structure 6 includes a rotary valve 61 and a drive component 62. The rotary valve 61 is cylindrical and rotatably disposed at the intersection of the first end of the guide channel 5, the outlet end of the inlet channel 13, and the flow channel 31, and located near the inlet end of the inlet channel 311 of the flow channel 31. The second spray component 3 has an opening for the rotary valve 61 to be exposed. The outer peripheral wall of the rotary valve 61 has three flow channels 611 arranged circumferentially. The flow channels 611 extend along the length of the rotary valve and intersect inside the rotary valve 61, connecting at the intersection. Specifically, the cross-section of the three flow channels 611 is generally herringbone-shaped. The drive component 62 is a fourth motor. The power output end of the fourth motor is connected to the rotary valve 61 to drive the rotary valve 61 to rotate along its own axis to selectively achieve the first state, the second state, or the third state through the corresponding flow channel 611. The axis of the aforementioned rotary valve extends along its length. The three flow channels 611 are designated as the first flow channel A, the second flow channel B, and the third flow channel C. When the rotary valve 61 is rotated to the point where the flow channel 31 is connected from the first flow channel A to the second flow channel B, the inlet end of the first flow channel A faces the flow channel 31, and the outlet end of the second flow channel B faces the guide channel 5. This achieves the second state where the guide channel 5 is connected to the flow channel 31, while the third flow channel C is in contact with the inner wall of the inlet channel 311 and is in a closed state. When the rotary valve 61 is rotated to the point where the inlet channel 13, the second flow channel B, and the first flow channel A are connected, the inlet end of the second flow channel B faces the inlet channel. In channel 13, the outlet end of the first flow channel A faces the guide channel 5, thus realizing the third state in which the inlet channel 13 and the guide channel 5 are connected, and the third flow channel C is in the closed state; when the rotary valve 61 is rotated to the state in which the inlet channel 13 is connected to the first flow channel A and the second flow channel B via the third flow channel C, the outlet ends of the first flow channel A and the second flow channel B face the inlet channel 311 of the second spray element 3, thus realizing the first state in which the inlet channel 13 and the inlet channel 311 of the second spray element 3 are connected.

[0057] Alternatively, the second or third state can be achieved by connecting C and A in the three flow channels, while the first state can be achieved by connecting B to A and C. As long as the first, second, or third state can be selectively achieved during the rotation of the rotary valve.

[0058] like Figures 1 to 6As shown, there are two side spray members 7 in this embodiment, which are arranged laterally side by side on the inner wall of the washing chamber 100. In this embodiment, they are specifically arranged on the rear wall of the washing chamber 100, and the rear wall of the washing chamber 100 is partially recessed at the position corresponding to the side spray member 7 to form a cavity 1000, and the side spray member 7 is installed in the corresponding cavity 1000. The above-mentioned guide channel 5 has a guide section 51 that partially surrounds the periphery of the side spray member 7, and part of the guide section 51 is a heating section 511 used to heat its inner cavity. The presence of the heating section 511 preheats the water flow during the water inlet process, thereby reducing the heating area required by the existing bottom heating plate, improving the working efficiency of the heating plate during the main wash, and the smaller heating plate also increases the space utilization of other bottom components. There are two guide sections 51, which are located on the periphery of the corresponding side spray members 7, and the two guide sections 51 are arranged symmetrically. The flow channel 5 also includes a connecting section 52 that is connected to each flow section 51. The connecting section 52 is located below the flow section 51 and is connected to the drainage cavity 101.

[0059] In addition, the aforementioned side spray component 7 can also be installed on the left side wall, right side wall, or front side wall.

[0060] The two side spray units mentioned above achieve cross-washing of dishes, etc. The two side spray units 7 have the same structure; the following explanation uses one of the side spray units 7 as an example. Figure 3 , Figure 11 and Figure 12 As shown, the side spray component 7 includes a mounting shaft 71 and a spray channel 731. The mounting shaft 71 is used to mount the washing chamber 100 onto the inner wall panel, and the interior of the mounting shaft 71 is hollow, forming an exhaust channel 711 for venting gas from the washing chamber 100. Furthermore, the cross-sectional area of ​​the aforementioned mounting shaft 71 gradually increases along the internal airflow direction. This facilitates the venting of gas from the washing chamber.

[0061] like Figure 12As shown, the aforementioned spray channel 731 is located on the periphery of the mounting shaft 71 and is in fluid communication with the water inlet 700. Specifically, a plurality of annular plates 72 are arranged at intervals along the axial direction on the outer peripheral wall of the mounting shaft 71, with the area near the center of the annular plates 72 protruding towards the gas flow direction within the mounting shaft 71. Along the gas flow direction within the exhaust channel 711, the outer periphery of each annular plate 72 gradually expands outward, that is, along the gas flow direction within the exhaust channel 711, the outer periphery of each annular plate 72 is arranged at intervals outward along the length direction of the guide ribs 73. Specifically, in this embodiment, the annular plates 72 are circular, and the diameter of each annular plate 72 gradually increases along the gas flow direction within the exhaust channel 711. A plurality of guide ribs 73 are arranged radially around the mounting shaft 71 between two adjacent annular plates 72, and the aforementioned spray channel 731 is formed between two adjacent guide ribs 73. To facilitate the flow of water from the inlet 700 into the spray channel 731, a plurality of circumferentially spaced protrusions 74 are provided on the outer peripheral wall of the mounting shaft 71, all extending axially along the mounting shaft 71. An annular piece 72 is mounted on the outer wall of the protrusions 74. Figure 12 As shown, in this embodiment, there are four protrusions 74, arranged at circumferential intervals. A water passage 741 is formed between two adjacent protrusions 74, connecting the water inlet 700 and the corresponding spray channel 731. One of the water passages 741 is connected to the four corresponding spray channels 731. In addition, the protrusions can also be in the same number as the guide ribs 73, or each water passage 741 can correspond to two, three, or more than four spray channels 731.

[0062] like Figure 11 As shown, the two side spray elements 7 are connected by a connecting channel 81. The connecting channel 81 extends laterally and has an opening 810 near its center. The inlet ends of the branch channels 811 on both sides of the opening 810 are the water inlets 700 of the corresponding side spray elements 7. The draining chamber 101 is in fluid communication with the water inlet 700 through a water guide channel 8, thereby supplying water to the water inlets 700 of the side spray elements 7 through the draining chamber 101. The aforementioned water guide channel 8 also includes a transverse section 82 located below the washing chamber 100 and a vertically extending extension section 83. One end of the transverse section 82 is connected to the draining chamber 101, and the other end of the transverse section 82 is connected to the extension section 83. There are two water guide channels 8, located on both sides of the connecting section 52. One end of the guide section 51 passes laterally through the corresponding side extension section 83 and is connected to the connecting section 52. See details. Figure 15As shown. The extensions 83 of the two water guiding channels 8 are connected to the opening 810 via the water flow channel 84. The water flow channel 84 extends vertically, and a through hole 841 communicating with the connecting channel 81 is provided on the top wall of the water flow channel 84. In order to facilitate the rapid flow of water into the two branch channels 811, a second impeller 85 is provided in the opening 810 to rapidly flow water into the two branch channels. Thus, the second impeller 85 is located between the two side spray members 7. The aforementioned second impeller 85 is arranged to be rotatable relative to the connecting channel 81. The second impeller 85 can rotate under the drive of the water flow or under the drive of a driving member. In this embodiment, it is driven by a driving member. Specifically, the second impeller 85 rotates under the drive of a second motor 86, and the second impeller 85 is mounted on the output shaft of the second motor 86, which is located in the opening 810.

[0063] The upward spraying in the above embodiments includes, but is not limited to, vertical upward spraying; it can also be inclined upward spraying, as long as it can spray upwards. The downward spraying includes, but is not limited to, vertical downward spraying; it can also be inclined downward spraying, as long as it can spray downwards. The "multiple" mentioned above refers to three or more.

[0064] The working process of the above-mentioned cleaning machine is as follows:

[0065] The fourth motor drives the rotary valve 61 to rotate to the B-to-A open state (C closed). This is the normal water intake state for the washing machine, where water from the inlet channel 13 enters the guide channel 5, passes through the symmetrically arranged guide sections 51, converges into the connecting section, and finally enters the drain chamber 101. During the washing process, when a portion of the water in the drain chamber 101 at the bottom of the washing machine enters the first spray element 2, another portion enters the water flow channel 84 along the guide channel 8. The second impeller 85 rotates, increasing the speed and pressure, and then throws the water into the two side channels 811, which then flow into the water passage channel 741. Because the sprayed water has a certain speed and pressure, the water sprayed from the water passage channel 741 quickly flows along the corresponding layer's spray channel 731 and is ultimately guided and sprayed onto the tableware surface, achieving horizontal cleaning within the space. See details... Figure 4 The direction indicated by the hollow arrow compensates for the insufficient effectiveness of the vertical cleaning from bottom to top by the first spray component 2. Thus, vertical cleaning from bottom to top is achieved through the first spray component 2, while horizontal cleaning of dishes and other kitchen utensils is achieved through the side spray components.

[0066] When the cleaning machine is about to finish cleaning, it will open the independent water inlet channel 13. When the rotary valve 61 is rotated to the C to AB conduction state, the water in the water inlet channel 13 enters the inlet channel 311 of the second spray element 3. The diversion grid plate 3111 in the inlet channel 311 reduces the occurrence of water eddies. The water impacts the third impeller 32, generating a circumferential force, causing the third impeller 32 to rotate and be thrown into the various diversion channels 315 in the connecting channel. The baffle plate 314 in the connecting channel reduces the occurrence of water eddies. Thus, the water entering the diversion channel 315 is sprayed from the second spray hole 3151 onto the upper surface of the tableware, ultimately achieving a top-to-bottom full-coverage rinsing. In this way, the second spray element 3 can rinse away the residue attached to the surface of the tableware facing away from the first spray element 2. In the final stage of cleaning, it provides a top-to-bottom full-coverage rinsing, which increases the guarantee for improving the overall cleaning effect of the tableware.

[0067] When the washing machine starts its drying function, the fourth motor drives the rotary valve 61 to rotate to the A-to-B open state (C closed). At this time, the fan 4 inside the door body turns on, drawing in fresh drying air from the air inlet 120 on the side of the door body and blowing it into the washing chamber. The drying airflow travels along the inlet channel 311 and the connecting channel 312, finally being sprayed into the washing chamber 100 from the second spray hole 3151. Meanwhile, another part of the drying airflow is squeezed at the air outlet 411 of the air guide pipe 41 and flows in the opposite direction through the recessed area 3113. See details. Figure 5 and Figure 4 The direction indicated by the middle arrow; the airflow enters the guide channel 5 through the rotating valve 61, and then enters the draining chamber 101. Part of the drying airflow is used to specifically dry areas near the draining chamber 101 where water tends to accumulate, keeping this area dry and preventing dampness and bacterial growth that could contaminate the tableware. The other part of the drying airflow enters the first spray element 2 and flows downwards and upwards, working in conjunction with the top-down drying airflow to achieve full-coverage convection drying of the tableware surface. While the drying airflow is blowing into the washing chamber 100, the moisture in the original washing chamber 100 is discharged through the exhaust channel 711 in the mounting shaft 71, maintaining the air pressure balance in the washing chamber 100.

[0068] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
