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 dishwashers, such as the Chinese utility model patent "Dishwasher" (patent number ZL202020455165.9, authorization announcement number CN212165744U), disclose a dishwasher including a cabinet, a spray unit, a lifting device, and a rangefinder. The cabinet has a cleaning compartment for holding tableware to be washed. The spray unit is located inside the cabinet and sprays liquid to clean the tableware in the cleaning compartment. The lifting device includes a drive unit and a guide unit. The drive unit is located at the top of the cabinet, and at least a portion of the drive unit is vertically movable. The drive unit is driven by the spray unit to drive its movement, and the guide unit cooperates with the spray unit to guide it. Although the spray unit can move up and down to adjust the cleaning height under the drive of the lifting device, it requires an additional lifting device (containing the drive unit, i.e., a power source), increasing the structural complexity and energy consumption of the dishwasher.

[0004] Therefore, further improvements are needed to the existing cleaning machines. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a cleaning machine that can achieve the purpose of raising and lowering the spray body without the need for a power source, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine with improved cleaning capabilities.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine with improved drying capacity.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a cleaning machine, comprising:

[0009] The cleaning tank has a hollow interior forming a washing chamber, and a water supply pipe is provided on its first side wall. The water outlet end of the water supply pipe has an upwardly extending vertical pipe section.

[0010] The spray body is vertically arranged in the washing chamber and installed on the vertical pipe section. It has a cavity that communicates with the inner cavity of the water supply pipe, and spray holes that communicate with the washing chamber and the cavity are opened on the first wall plate away from the first side wall.

[0011] The feature is that: the cavity is provided with a first baffle on the first wall plate, a second baffle on the second wall plate opposite to the first wall plate and having a water inlet, and a guide channel for guiding water after passing through the water inlet toward the first baffle; the second baffle and the first baffle are located on the water flow path and below the guide channel; the bottom of the spray body has a water inlet channel near the second baffle for intermittent water supply, the water inlet channel extending vertically and installed on a vertical pipe section; the cleaning machine also includes:

[0012] The first impeller is disposed in the cavity, located between the first and second baffles, and rotates around its own axis under the action of the water flowing out through the water inlet channel, thereby driving the water flow to push the second baffle upward and then push the spray body upward relative to the vertical pipe section. When the water flow pushes the first baffle downward after passing through the guide channel, it drives the spray body to move downward relative to the vertical pipe section.

[0013] The spray body can extend vertically or along the arrangement direction of the two second sidewalls. However, preferably, the sidewall of the cleaning tank adjacent to the first sidewall is the second sidewall, the spray body extends along the arrangement direction of the two second sidewalls, and the rotation axis of the first impeller extends along the extension direction of the spray body.

[0014] There are various structural forms of the first impeller, but preferably, the first impeller includes a rotating shaft mounted on the spray body and blades arranged on the outer peripheral wall of the rotating shaft and extending laterally. There are at least two blades, which are arranged at intervals along the circumference of the rotating shaft. The blades located between the rotating shaft and the second wall plate are located on the water flow path of the water inlet channel.

[0015] The second baffle can have one or more water inlets. From the perspective of improving cleaning ability, preferably, the second baffle has multiple water inlets arranged at intervals along the length of the spray body.

[0016] The second baffle can have various structural forms, including a wavy shape or a straight strip. However, preferably, the second baffle is a wavy strip extending along the length of the spray body, with the water inlet located at the corner of the second baffle. This structure increases the contact area between the second baffle and the water, thereby enhancing the upward thrust on the spray body.

[0017] The two ends of the second baffle can be connected to the corresponding side wall of the spray body, or a gap can be left. However, preferably, a gap is left between the two ends of the second baffle and the corresponding side wall of the spray body to allow water to pass through.

[0018] To facilitate water intake, there are multiple water inlet channels, which are arranged at intervals along the length of the spray body and staggered from the water outlet. Each water inlet channel corresponds to a vertical pipe section.

[0019] Preferably, the water supply pipeline includes a fixed pipeline and a connecting pipeline disposed on the fixed pipeline and extending along the length of the spray body. The top wall of the connecting pipeline has multiple outlets spaced apart along its length, and the periphery of each outlet extends upward to form a vertical pipe section. This prevents interference between water entering each water inlet channel and facilitates uniform water intake into each channel.

[0020] In order to make the spray body move upward intermittently to improve the focused cleaning of each position, there are multiple second baffles, which are arranged at intervals along the vertical direction, and the water outlets on each second baffle are arranged accordingly.

[0021] In order to facilitate the flow of water from each water inlet toward the first baffle, a flow guide channel is provided in the cavity at the position corresponding to each water inlet, and the inlet of the flow guide channel is connected to the corresponding water inlet.

[0022] The first baffle can have various structural forms, such as an arc shape, a straight strip, or other shapes. However, preferably, the first baffle is a first baffle bar along the length direction of the spray body.

[0023] In order to facilitate the collection of water and allow it to spray out from the nozzle, the first baffle gradually tilts upwards toward the second wall panel.

[0024] To improve cleaning capability, there are multiple first baffles, which are spaced apart along the vertical direction. Each first baffle is provided with a set of spray holes, and each set contains at least one spray hole.

[0025] To achieve filtration and water supply to the spray body, the bottom of the washing chamber has a downwardly recessed draining cavity at least in the central part, the draining cavity is covered with a drain plate with drain holes, the cavity of the spray body is connected to the draining cavity through a water supply pipe, and along the fluid flow path, the cavity is located downstream of the draining cavity.

[0026] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: a side spraying component that can rotate relative to the second side wall is provided on the second side wall of the cleaning tank. The side spraying component has a water channel inside, and the side spraying component has a spray hole on the first side plate away from the first side wall that sprays into the washing chamber. The spray hole is connected to the water channel. The side spraying component is inclined from top to bottom towards the second side wall, and the rotation axis of the side spraying component forms an acute angle with the horizontal plane.

[0027] Thus, as the side spray unit rotates, the spray holes on it will spray the object to be cleaned obliquely from top to bottom. The residue on the object to be cleaned is more easily removed by the downward scouring force, and it can cover the upper part of the object to be cleaned, completing a relatively three-dimensional rinsing and achieving a better cleaning effect.

[0028] Preferably, at least one transversely arranged water outlet pipe is provided on the second side wall of the washing chamber, and the side spray member has a water inlet hole on the second side plate opposite to the second side wall that communicates with the water passage. The water inlet hole of the side spray member is detachably installed on the water outlet pipe and communicates with the water outlet pipe.

[0029] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: the drying airflow in the exhaust channel is sprayed out by the spray body, thereby drying the items to be cleaned by circulating it up and down, which improves the drying effect; in addition, the drying airflow flows into the draining chamber through the fixed pipe to achieve the drying of the draining chamber.

[0030] To prevent water from overflowing into the exhaust duct, the fixed pipe has a vertically extending water delivery section. An adjustable baffle is installed within the inner cavity of this water delivery section. The connecting port is located on the side wall of the water delivery section and along the moving path of the baffle. A gap is maintained between the baffle and the inner circumferential wall of the water delivery section to allow water to pass through. Under the pressure of water flow, the baffle moves upward to close the connecting port. In the drying state, the baffle is at least partially positioned below the connecting port, thus opening it. The presence of the baffle prevents water from flowing into the drying mechanism and affecting its service life.

[0031] In order to accommodate and restrict the vertical position of the blocking component, an upper baffle and a lower baffle are arranged at intervals in the inner cavity of the water conveying section. The upper baffle and the lower baffle are connected by a vertically extending connecting strip. The connecting port is located between the upper baffle and the lower baffle. The side wall where the upper baffle, the lower baffle, the connecting strip and the connecting port are located encloses the space for accommodating the blocking component.

[0032] In order to drain the overflow water in a timely manner, a drainage channel connected to the connecting port is provided below the exhaust channel.

[0033] Compared with the prior art, the advantages of the present invention are as follows: The cavity of the cleaning machine is equipped with a first baffle, a second baffle, and a first impeller. The intermittent water flow from the water inlet channel drives the first impeller to rotate around its own axis. At this time, the first impeller drives the water flow to push the second baffle upward. Since the second baffle is connected to the spray body, it will drive the spray body to move upward. Under the action of the first impeller, when the water flow flows through the guide channel to the first baffle, it pushes the first baffle downward. At this time, it will drive the spray body to move downward. In this way, the first impeller realizes the change of direction of the water flow, and then realizes the up and down movement of the spray body through the flow of water. The water flow sprayed by the spray body moves up and down, thereby cleaning the objects to be cleaned at different heights back and forth. The up and down movement of the entire spray body does not require a power source to drive it, saving costs and reducing the energy consumption of the cleaning machine. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] like Figures 1 to 8 As shown, the washing machine of this embodiment is used to wash dishes or fruits and vegetables. The washing machine includes a washing tank 4, a spray device 01, a side spray component 2, a spray body 3, and a water pump assembly 7.

[0044] like Figure 1 and Figure 2 As shown, the washing tank 4 described above has a hollow interior forming a washing chamber 40. The bottom of the washing chamber 40 has a downwardly recessed draining cavity 401 at its center. The draining cavity 401 is covered by a draining plate 42 with drain holes 420. A spray device 01 is located on the draining plate 42 and is arranged to rotate relative to the draining plate 42. Furthermore, the draining plate 42 has multiple slag discharge ports 421 arranged circumferentially around the drain holes 420.

[0045] like Figure 3 and Figure 4 The spray device 01 described above includes a spray arm 1 and a secondary spray arm 15. The spray arm 1 has a flow channel 10 inside, and includes a main body 11 and at least one set of spray arm assemblies 12 formed on the outer peripheral wall of the main body 11. Specifically, there are three sets of spray arm assemblies 12, arranged at intervals along the outer peripheral wall of the main body 11. Alternatively, two or more sets of spray arm assemblies 12 may be used. Each set of spray arm assemblies 12 has the same structure; the following description uses one set as an example.

[0046] like Figure 2 As shown, the bottom of the main body 11, near the center, has a water inlet channel 111 that communicates with the flow channel 10. The water pump assembly 7 is used to pump water from the drain chamber 401 through the water inlet channel 111 into the flow channel 10 of the spray arm 1. The water pump assembly in this embodiment is the same as that in the applicant's prior patent application, and will not be described in detail here. Figure 3 and Figure 4 As shown, the spray arm assembly 12 includes two circumferentially spaced spray arms that extend laterally outward along the main body 11. Each spray arm has at least one slag-sweeping hole near its bottom for downward spraying to sweep away slag. Specifically, the bottom of the opposite side walls of the spray arms, spaced apart along the rotation direction, each has an inclined section 12a that gradually slopes downward toward the center of the spray arm. The slag-sweeping hole is located near the free end of the corresponding inclined section 12a of the spray arm and is connected to the flow channel 10. The aforementioned slag discharge port 421 is located in the spray direction of the corresponding slag-sweeping hole. In this embodiment, the two spray arms are a first spray arm 121 and a second spray arm 122. The space between the first spray arm 121 and the second spray arm 122 and extending downward to the bottom of the washing chamber is region 14. In this embodiment, the rotation trajectory of the free end of the first spray arm 121 is located outside the rotation trajectory of the free end of the second spray arm 122. In this embodiment, the first spray arm 121 is L-shaped and the second spray arm 122 is S-shaped. Alternatively, both the first spray arm 121 and the second spray arm 122 can be L-shaped, or both can be S-shaped, or other shapes can be used.

[0047] like Figure 4 As shown, the slag-sweeping holes on the first spray arm 121 are called first slag-sweeping holes 1211, and each first spray arm 121 has three first slag-sweeping holes, but two or more can also be used. The slag-sweeping holes on the second spray arm 122 are called second slag-sweeping holes 1221, and each second spray arm 122 has two second slag-sweeping holes 1221, but two or more can also be used. The spraying directions of the first slag-sweeping holes 1211 and the second slag-sweeping holes 1221 are both directed toward the region 14 of the corresponding spray group 12. Specifically, the spraying directions of the first slag-sweeping holes 1211 and the second slag-sweeping holes 1221 intersect, and the intersection point is located within the region 14 of the spray arm group 12. In addition, the spray direction of the first slag-sweeping hole 1211 in all spray arm assemblies 12 is generally clockwise, and the spray direction of the second slag-sweeping hole 1221 in all spray arm assemblies 12 is generally counterclockwise. The rotation trajectory of the first slag-sweeping hole 1211 is located outside the rotation trajectory of the second slag-sweeping hole 1221.

[0048] like Figure 3 As shown, the auxiliary spray arm 15 has a water flow channel inside, and the bottom of the auxiliary spray arm 15 has a liquid inlet hole communicating with the water flow channel. The top wall plate has a spray hole 152 communicating with the water flow channel. In addition, a spray hole 152 may also be provided on the top wall of the first spray arm 121. At least one of the sub-spray arms in the above-mentioned spray arm group 12 has a vertically extending liquid outlet channel 120 on its top surface. Specifically, each of the above-mentioned first spray arms 121 has a plurality of liquid outlet channels 120 arranged at intervals along its respective length direction. The liquid inlet hole of the auxiliary spray arm 15 can be selectively installed at one of the liquid outlet channels 120 and communicate with the liquid outlet channel 120.

[0049] like Figures 5 to 7 As shown, a water supply channel 47 is provided on the first side wall 43 of the washing chamber 40. The water supply pipe 47 includes a fixed pipe 470 and a connecting pipe 472 that is disposed on the fixed pipe 470 and extends along the length direction of the spray body 3. The lower end of the fixed pipe 470 is connected to the drain chamber 401. Multiple outlets are provided on the top wall of the connecting pipe 472 that are spaced apart along their own length direction. The periphery of the outlet extends upward to form a vertical pipe section 471. Thus, in this embodiment, there are multiple vertical pipe sections 471.

[0050] The sidewall adjacent to the first sidewall 43 in the washing chamber 40 is the second sidewall 44. The spray body 3 is vertically arranged within the washing chamber 40 and extends along the arrangement direction of the two second sidewalls 44. The interior of the aforementioned spray body 3 has a cavity 30 that communicates with the inner cavity of the water supply pipe 47. At the bottom of the spray body 3, at the position corresponding to the vertical pipe section 471, a water inlet channel 302 is provided for intermittent water supply. Multiple water inlet channels 302 are arranged at intervals along the length of the spray body 3. The water inlet channels 302 of the spray body 3 are installed on the corresponding vertical pipe section 471. The cavity 30 of the spray body 3 communicates with the inner cavity of the vertical pipe section 471. Thus, the water supply pipe 47 connects the drain chamber 401 and the cavity 30 of the spray body 3, and along the water flow path, the cavity 30 is located downstream of the drain chamber 401.

[0051] The aforementioned spray body 3 has spray holes 301 on the first wall panel 31 away from the first side wall 43, which connects the washing chamber 40 and the cavity 30. The wall panel opposite to the first wall panel 31 of the spray body 3 is the second wall panel 32. The cavity 30 is provided with a first baffle on the first wall panel 31, a second baffle on the second wall panel 32, a first impeller 5, and a guide channel 33. The second baffle and the first baffle are located on the water flow path. Along the water flow path, the second baffle, the guide channel 33, and the first baffle are arranged in sequence. The aforementioned guide channel 33 is located above the first baffle and the second baffle.

[0052] like Figures 5 to 7 As shown, there are multiple first baffles, arranged at intervals along the vertical direction. Each first baffle has the same structure; the following description uses one of these baffles as an example. The first baffle is a first baffle strip 311 along the length of the spray body 3, which gradually slopes upwards towards the second wall panel 32. Each first baffle strip 311 has a set of spray holes 301, with at least one spray hole 301 in each set. In this embodiment, each set has at least multiple spray holes 301, arranged at intervals along the length of the first baffle strip 311.

[0053] There are multiple second baffles, arranged at intervals along the vertical direction. Each second baffle has a basically the same structure; the following description uses one of these second baffles as an example. Multiple water inlets 3211 are spaced along the length of the spray body 3 on each second baffle. The water inlet channel 302 is staggered with the water inlets 3211. Specifically, the second baffle is a second baffle strip 321 extending along the length of the spray body 3 and having an overall wavy shape. The water inlets 3211 are located at the corners of the second baffle strip 321, and gaps are left between the two ends of the second baffle strip 321 and the corresponding sidewalls of the spray body 3 for water to pass through. The water inlets 3211 on each of the second baffle strips 321 are arranged vertically in a corresponding manner, forming a group. Each group of water inlets corresponds to a guide channel 33. The inlet of the guide channel 33 is connected to the corresponding water inlet 3211, thereby guiding the water passing through the water inlet 3211 towards the first baffle strip 311.

[0054] The aforementioned water inlet channel 302 is arranged adjacent to the second baffle 321. The aforementioned first impeller 5 is located between the first baffle 311 and the second baffle 321. Specifically, the aforementioned first impeller 5 includes a rotating shaft 51 mounted on the spray body 3 and blades 52 arranged on the outer peripheral wall of the rotating shaft 51 and extending laterally. There are at least two blades 52, which are arranged at intervals along the circumference of the rotating shaft 51. The rotating shaft 51 extends along the extension direction of the spray body 3. The blades 52 located between the rotating shaft 51 and the second baffle 321 are located on the water flow path of the water inlet channel 302. The aforementioned first impeller 5 rotates around its own axis under the drive of the water flow flowing out of the water inlet channel 302. Thus, the first impeller 5 drives the water flow to push the second baffle 321 upward, thereby pushing the spray body 3 upward relative to the vertical pipe section 471. When the water flow pushes the first baffle 311 downward after passing through the guide channel 33, it will drive the spray body 3 downward relative to the vertical pipe section 471. That is, when the spray body 3 moves up and down, the water inlet channel 302 moves up and down relative to the vertical pipe section 471. The rotation axis of the first impeller 5 is the axis of the rotating shaft 51.

[0055] Since the water flow in the inlet channel is intermittent, after the spray body 3 has finished moving downwards, water is then flowed into the inlet channel again, thus achieving the up-and-down movement of the spray body 3 in a cycle.

[0056] To achieve the drying of the items to be washed in the washing chamber, such as Figure 8As shown, a drying mechanism 9 is provided on the outer wall of the cleaning tank 4, and the drying mechanism 9 is located on the side wall where the spray body 3 is located. The aforementioned drying mechanism 9 has an exhaust channel 91 for discharging hot air. The exhaust channel 91 includes a vertically arranged vertical channel 911 and a horizontal channel 912 located downstream of the vertical channel 911. The inner peripheral wall of the vertical channel 911 gradually narrows inward from top to bottom to prevent overflow water from entering the drying mechanism. The aforementioned fixed pipe 470 has a vertically extending water conveying section 4711. A blocking member 48 that can move up and down is provided in the inner cavity of the water conveying section 4711, and a connecting port 4712 connected to the exhaust channel 91 is opened on the side wall of the water conveying section 4711. The connecting port 4712 is located on the moving path of the blocking member 48. A gap is left between the aforementioned blocking member 48 and the inner peripheral wall of the water conveying section 4711 to allow water to pass through. The blocking member 48 moves upward under the push of the water flow to close the connecting port 4712. In the drying state, the blocking member 48 moves downward under its own gravity until it is partially below the connecting port 4712, thus opening the connecting port 4712. Alternatively, the blocking member 48 can be moved downward until it is completely below the connecting port 4712 to open it. The presence of the blocking member prevents water from flowing into the drying mechanism and affecting its service life. The drying mechanism in this embodiment can adopt a structure from the prior art, which will not be described in detail here.

[0057] In order to drain the overflow water in a timely manner, such as Figure 8 As shown, a drainage channel 05 connected to the connecting port 4712 is provided below the exhaust channel 91. Specifically, the aforementioned drainage channel 05 is located below the horizontal channel 912 and is connected to the drain pipe. In order to improve the overflow prevention effect, the drainage pipe 05 adopts a partial bend structure. In order to limit the vertical position of the blocking member 48, an upper baffle 4713 and a lower baffle 4714 are arranged vertically and alternately in the inner cavity of the water conveying section 4711. The upper baffle 4713 and the lower baffle 4714 are connected by a vertically extending connecting strip 4715. The connecting port 4712 is located between the upper baffle 4713 and the lower baffle 4714. The side wall where the upper baffle 4713, the lower baffle 4714, the connecting strip 4715 and the connecting port 4712 are located encloses a space for accommodating the blocking member 48.

[0058] like Figure 3As shown, the side spray member 2 is rotatably mounted on the second side wall 44 of the washing chamber 40, and is a straight spray arm. The side spray member 2 is inclined from top to bottom towards the first side wall, and the axis of rotation of the side spray member 2 forms an acute angle θ with the horizontal plane A. The side spray member 2 has a water channel 20 inside, and the side spray member 2 has a spray hole 201 on the first side plate 2a away from the second side wall 44, which sprays into the washing chamber 40. The spray hole 201 is connected to the water channel 20, and the spray hole 201 sprays downward at an angle. The side spray member 2 has a water inlet hole 202 on the second side plate 2b adjacent to the second side wall 44, which is connected to the water channel 20. The second side plate 2b is arranged opposite to the first side plate 2a.

[0059] like Figure 1 and Figure 3 As shown, at least one horizontally arranged water outlet pipe 41 is provided on the second side wall 44 of the washing chamber 40. Specifically, there are at least two water outlet pipes 41, arranged at intervals along the vertical direction. In this embodiment, there are three water outlet pipes 41, but more than three or two can also be used. In addition, the water supply pipe 5 connects the drain chamber 401 and the water outlet pipes 41. Along the fluid flow path, the aforementioned water outlet pipes 41 are located downstream of the drain chamber 401. Thus, water in the drain chamber 401 flows into the water outlet pipes 41 through the water supply pipe 5. In this embodiment, the water outlet pipes 41 are partially located inside the water supply pipe 5, and a water inlet 411 connecting the water supply pipe 5 and the water outlet pipes 41 is provided on the side wall of the water outlet pipes 41.

[0060] In order to guide the water flow in the draining chamber to the outlet pipe 41 and the inlet channel 302, a second impeller 6 is provided upstream of the water supply pipe 5 and the water delivery pipe 47. The second impeller 6 is installed on the output shaft of the motor of the water pump assembly 7 and is located downstream of the draining chamber 401.

[0061] The water inlet 202 of the aforementioned side spray component 2 is selectively installed on one of the water outlet pipes 41 and is connected to the water outlet pipe 41. In order to achieve detachable installation of the water inlet of the side spray component 2 and the water outlet pipe 41, specifically, a baffle 42 is provided inside the water outlet pipe 41, which can move back and forth along the water flow direction (i.e., transverse) to open or close the outlet of the water outlet pipe 41, and a second elastic member acts on the baffle 42 and makes the baffle 42 always have the tendency to move in the outlet direction to close the outlet. The second elastic member is a transversely arranged spring 43, the first end of the spring 43 is connected to the baffle 42, and the second end of the spring 43 is in contact with the wall plate at the corresponding position of the water supply pipe 5. The side spray component 2 is provided with a mounting bracket 21 that can rotate relative to the side spray component 2. The mounting bracket 21 includes an annular member 210 and a connecting rod 212 located within the annular member 210. The connecting rod 212 has an extension rod 211 extending away from the side spray component 2, that is, one end of the extension rod 211 is connected to the connecting rod 212. In this embodiment, the extension rod 211 extends in a horizontal direction, and the extension direction of the extension rod 211 forms an acute angle θ with the rotation axis of the side spray component 2. When the side spray component 2 is installed in the water outlet pipe 41, the mounting bracket 21 is limited on the water outlet pipe 41, and the extension rod 211 is inserted into the water outlet pipe 41 to push the baffle 42 to move away from the side spray component 2 until the outlet is opened.

[0062] There are multiple ways to limit the mounting bracket 21 and the water outlet pipe 41. They can be connected by snap-fit, threaded connection, or other methods, as long as they can limit the movement of both. These methods will not be described in detail in this embodiment.

[0063] like Figures 5 to 7As shown, a water inlet pipe 49 for supplying water to the washing chamber 40 and a heating element 491 for heating the water inlet pipe 49 are provided on the outer wall of the washing tank 4 near the bottom. The heating element can be in the form of a heating module, a PTC heating element, or other heating element structures, which will not be described in detail in this embodiment. The water inlet pipe 49 surrounds the periphery of the washing tank 4. Specifically, the water inlet pipe 49 is spirally wound around the outer wall of the washing tank 4 from top to bottom. A water inlet is provided on the second side wall of the washing chamber 40 opposite to the spray body 3. In this embodiment, the outlet end of the water inlet pipe 49 is connected to the water inlet of the washing chamber 40 through a connecting pipe 492. When water enters during the washing process, the water is preheated before passing through the water inlet pipe, thereby reducing the heating area required for the existing bottom heating plate in the washing tank during washing and improving the working efficiency of the heating plate during the main wash. A smaller heating plate can be used, thus increasing the space utilization rate at the bottom. In addition, during drying, cold water is introduced into the water inlet pipe and placed around the bottom of the washing chamber. This can accelerate the condensation of hot and humid vapors at the bottom of the washing chamber, improve heat exchange efficiency, and further enhance the overall drying efficiency inside the washing chamber.

[0064] The drying mechanism in the above embodiments can be any drying mechanism in the prior art, and will not be described in detail in this embodiment.

[0065] The working process of the above-mentioned cleaning machine is as follows:

[0066] During cleaning, the water pump assembly 7 pumps water into the spray device and sprays it upwards through the spray holes 152. Meanwhile, water in the drain chamber 401, driven by the second impeller 6, enters the spray body 3 through the water supply pipe 47. The water flowing out through the water inlet channel drives the first impeller 5 to rotate around its own axis. At this time, the first impeller 5 drives the water flow upwards, pushing the second baffle 321 and subsequently pushing the spray body 3 upwards relative to the vertical pipe section 471. Conversely, when the water flows downwards through the guide channel 33, pushing the first baffle 311, it causes the spray body 3 to move downwards relative to the vertical pipe section 471. The water flow in the water inlet channel is intermittent; after the spray body 3 completes its downward movement, water is then introduced into the water inlet channel again, cyclically achieving the up-and-down movement of the spray body 3.

[0067] When the water in the drain chamber 401 is driven by the second impeller 6 and enters the water passage 20 of the side spray component 2 through the water outlet pipe 41, it will drive the side spray component 2 to rotate relative to the mounting bracket 21 and spray water into the washing chamber 40 through the spray hole 201. At this time, the water sprayed by the side spray component 2 flows horizontally downward. In this way, the horizontally downward water flow and the vertically upward water flow at the bottom intersect, realizing the vertical and horizontal intersection of the cleaning water flow, which improves the overall cleaning effect of the items to be cleaned.

[0068] During drying, part of the drying airflow enters the spray body 3 through the exhaust channel 91 and water conveyance section 4711, and is sprayed out through the spray holes 301, thus performing a downward-flowing, cyclical drying of the items to be cleaned. The other part flows through a fixed pipe into the drain chamber 401, thereby drying the interior of the drain chamber. Additionally, the water pump assembly drives the spray device to rotate, and the drying airflow is sprayed out through the water spray holes, accelerating the diffusion of the drying airflow and achieving targeted cleaning of the areas at the bottom of the cleaning tank prone to water accumulation. Thus, the combination of upward-flowing, cyclical rinsing and drying with bottom rotational drying achieves a three-dimensional drying effect in the cleaning tank.
