Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a washing machine for washing dishes or fruits and vegetables. Background Art

[0002] A cleaning machine is a device that sprays cold or hot water onto dishes to remove dirt adhered to the dishes or fruits and vegetables and clean the dishes or fruits and vegetables. Existing spray cleaning machines generally achieve spraying in all directions by rotating a sprayer.

[0003] Current dishwashers, such as the Chinese invention patent "A dishwasher rinsing and dishwashing powder adding device", whose patent number is ZL201610555274.6 (authorization announcement number is CN107616772B), disclose a dishwasher including an auxiliary spray arm and a bottom spray arm. The auxiliary spray arm is arranged on the inner wall of the dishwasher to spray water laterally into the dishwasher. Although the bottom spray and the lateral spray are used to achieve spray cleaning inside the dishwasher, when the dishes are sprayed laterally, residues may remain on the dishes waiting to be cleaned, thereby affecting the cleaning effect. In addition, the cleaning position cannot be adjusted, the cleaning range is small, and the cleaning is not comprehensive.

[0004] Therefore, it is necessary to further improve the existing cleaning machine. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a cleaning machine capable of adjusting the cleaning position in view of the current status of the above-mentioned prior art.

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

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine which can improve the bottom slag sweeping ability by cross-hedge slag sweeping.

[0008] The fourth technical problem to be solved by the present invention is to provide a cleaning machine capable of adjusting the cleaning height and the cleaning position.

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

[0010] A cleaning box, the interior of which is hollow to form a washing chamber, and a water delivery pipeline is arranged on the first side wall;

[0011] A spray body is vertically arranged in the washing chamber and movably connected to the water outlet end of the water delivery pipe, wherein the spray body has a cavity connected to the inner cavity of the water delivery pipe, and a plurality of spray holes are provided on the wall plate of the spray body for spraying into the washing chamber and connected to the cavity;

[0012] The invention is characterized in that a gap is left between the spray body and the first side wall, and the upper part of the spray body is arranged to be able to move close to or away from the first side wall.

[0013] There are many ways to achieve the movement of the upper part of the spray body. The upper part of the spray body can be automatically moved by a propulsion mechanism containing a power source, or it can be pushed without a power source. However, from the perspective of cost and energy saving, it is preferably also included a spray device rotatably arranged at a position adjacent to the bottom of the washing chamber, the spray device having a water spray hole that sprays upward. The upper part of the spray body is located on the flow path of the water sprayed from the water spray hole of the spray device, and swings toward the first side wall relative to the water pipe under the intermittent push of the water sprayed from the water spray hole on the rotating spray device.

[0014] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the upper part of the spray body has an inclined section which is gradually inclined from bottom to top away from the first side wall, the spray hole is opened on the inclined section, and the inclined section is located on the flow path of the water sprayed from the spray hole of the spray device.

[0015] The spray body can be in the form of an overall inclined section or a partially inclined section, but preferably, the spray body also includes a vertical section arranged vertically, the inclined section is located above the vertical section, and is connected to the bottom edge of the vertical section, and encloses the vertical section to form the cavity.

[0016] The inclined section and the vertical section mentioned above can be provided with spray holes at the same time. Specifically, the vertical section is provided with the spray holes.

[0017] The vertical section can be provided with a spray hole separately. Specifically, the spray body has a vertical section provided vertically, and the vertical section is provided with the spray hole.

[0018] Preferably, the cross section of the water outlet of the water delivery pipe is circular, and the water outlet has a plurality of through holes connecting the cavity and the inner cavity of the water delivery pipe, so as to realize the movable connection between the spray body and the water delivery pipe.

[0019] There are various structural forms of the spray device, but preferably, the spray device includes a spray arm and an auxiliary spray arm, at least one liquid outlet channel is arranged on the top wall plate of the spray arm, the auxiliary spray arm can be rotatably arranged on the liquid outlet channel, and the water spray hole is opened on the top wall plate of the auxiliary spray arm and / or the top wall plate of the spray arm.

[0020] In order to achieve the slag sweeping at the bottom of the cleaning box, the spray arm has a flow channel inside, and the bottom of the spray arm has a slag sweeping hole for sweeping the slag, and the slag sweeping hole is connected to the flow channel.

[0021] The technical solution adopted by the present invention to solve the above-mentioned third technical problem is: the spray arm includes a main body portion with a water inlet channel at the bottom and at least one spray arm group formed on the outer peripheral wall of the main body portion, the spray arm group includes two sub-spray arms arranged at intervals along the circumference of the main body portion and extending laterally outward, the water inlet channel is connected to the flow channel, and each of the sub-spray arms is provided with the above-mentioned slag sweeping hole at a position adjacent to the bottom, and the spraying direction of the slag sweeping hole of each sub-spray arm in the spray arm group is toward the area between the two sub-spray arms in the spray group.

[0022] In order to realize cross slag sweeping and further improve the slag sweeping capability, the two sub-spray arms in the spray arm group are respectively the first spray arm and the second spray arm, the slag sweeping hole on the first spray arm is the first slag sweeping hole, and the slag sweeping hole on the second spray arm is the second slag sweeping hole, and the spraying direction of the first slag sweeping hole in the spray arm group intersects with the spraying direction of the second slag sweeping hole, and the intersection is located in the area of ​​the spray arm group. In this way, the slag sweeping water flow sprayed through the first slag sweeping hole and the slag sweeping water flow sprayed through the second slag sweeping hole intersect, thereby forming a cross-rotating slag sweeping water flow, which improves the slag sweeping capability.

[0023] The spray arm group can be one group or more than two groups. However, from the perspective of good slag sweeping effect, preferably, there are at least two groups of spray arm groups, and they are arranged at intervals along the circumference of the main body. The spray directions of the first slag sweeping holes in all spray arm groups are generally clockwise, and the spray directions of the second slag sweeping holes in all spray arm groups are generally counterclockwise. In this way, cross-rotation slag sweeping is achieved to ensure the slag sweeping effect.

[0024] In order to improve the cleaning ability, a side spray part that can rotate relative to the second side wall is arranged on the second side wall of the cleaning box, the side spray part has a water passage inside, and the side spray part is provided with a spray hole spraying toward the washing chamber on the first wall plate away from the first side wall, the spray hole is connected with the water passage, the side spray part is in a state of gradually tilting from top to bottom toward the second side wall, and the rotation axis of the side spray part forms an acute angle with the horizontal plane. In this way, during the rotation of the side spray part, the spray hole thereon will obliquely spray the object to be cleaned from top to bottom, and the residue on the object to be cleaned will fall off more easily due to the flushing force from top to bottom, and can cover the upper part of the object to be cleaned, completing a relatively three-dimensional flushing, with a better cleaning effect.

[0025] 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 connected to the water channel on the second wall panel opposite to the second side wall, and the water inlet hole of the side spray member can be detachably mounted on the water outlet pipe and is connected to the water outlet pipe.

[0026] In order to adjust the cleaning height, there are at least two water outlet pipes, which are arranged at intervals along the up and down directions, and the side spray piece is selectively installed on one of the water outlet pipes.

[0027] In order to achieve filtration, the bottom of the washing chamber has a downwardly concave drain cavity at least in the central part, and the drain cavity is covered with a drain plate with drain holes. The spray device is located on the drain plate and is arranged to be rotatable relative to the drain plate.

[0028] In order to supply water to the spray body, the cavity of the spray body is connected to the drainage cavity through a water supply pipeline, and along the fluid flow path, the cavity is located downstream of the drainage cavity.

[0029] In order to dry the objects to be cleaned in the washing chamber, a drying mechanism is provided on the outer wall of the washing box, and the drying mechanism has an exhaust passage for hot air to be discharged, and the side wall of the fixed pipe has a connecting port connected to the exhaust passage. The drying airflow in the exhaust passage is sprayed downward through the spray body, so that the objects to be cleaned are dried in a diving up and down cycle, thereby improving the drying effect; in addition, the drying airflow flows into the drain chamber through the fixed pipe to dry the drain chamber.

[0030] In order to prevent water from overflowing into the exhaust channel, the fixed pipe has a vertically extending water delivery section, and a blocking member that can move up and down is arranged in the inner cavity of the water delivery section. The communication port is located on the side wall of the water delivery section and on the moving path of the blocking member. A gap for water to pass through is left between the blocking member and the inner peripheral wall of the water delivery section, and the blocking member moves upward under the push of the water flow to close the communication port. In the drying state, the blocking member is at least partially located below the communication port to open the communication port. The existence of the blocking member prevents water from flowing into the drying mechanism and affecting the service life of the drying mechanism.

[0031] In order to accommodate the blocking member and limit the upper and lower positions of the blocking member, an upper blocking bar and a lower blocking bar are arranged in the inner cavity of the water delivery section with an upper blocking bar and a lower blocking bar spaced apart from each other. The upper blocking bar and the lower blocking bar are connected by a vertically extending connecting bar, and the connecting port is located between the upper blocking bar and the lower blocking bar. The upper blocking bar, the lower blocking bar, the connecting bar and the side wall where the connecting port is located form a space for accommodating the blocking member.

[0032] In order to discharge the overflow water in time, a drainage channel connected to the connecting port is arranged under the exhaust channel.

[0033] A water inlet pipe for supplying water to the washing chamber and a heating element for heating the water inlet pipe are arranged on the outer wall surface of the washing box near the bottom, and the water inlet pipe surrounds the periphery of the washing box. In this way, when water is introduced in the washing state, the water will be preheated in advance when passing through the water inlet pipe, thereby reducing the heating area required for the heating plate at the bottom of the existing washing box during cleaning and heating, improving the working efficiency of the heating plate during the main washing, and using a heating plate with a smaller area, thereby increasing the space utilization rate at the bottom. In addition, when drying, cold water is introduced into the water inlet pipe and wrapped around the bottom layer of the washing box, which can accelerate the condensation speed of the hot and humid steam inside the washing box at the bottom, improve the heat exchange efficiency, and further improve the overall drying efficiency inside the washing chamber.

[0034] There are many structural forms of the water inlet pipe, which can be in the form of multiple water inlet pipes, in the form of a spiral water inlet pipe, or in other forms. However, preferably, the water inlet pipe is spirally wound on the outer wall of the cleaning box from top to bottom, and the water outlet end of the water inlet pipe is connected to the water inlet on the side wall of the cleaning box through a connecting pipe.

[0035] The technical solution adopted by the present invention to solve the above-mentioned fourth technical problem is: the water supply pipeline includes a fixed pipeline and a movable pipe section located above the fixed pipeline and capable of moving up and down relative to the fixed pipeline; the spray body is installed on the movable pipe section and moves up and down relative to the fixed pipeline under the drive of the driving mechanism.

[0036] There are many forms of driving mechanisms for realizing the up and down movement of the spray body, which can be in the form of a lifting cylinder, or in the form of a motor, a screw and a nut, or in other forms. However, preferably, the side wall of the cleaning box arranged adjacent to the first side wall is the second side wall, and a mounting seat is provided on the inner wall surface of at least one of the two second side walls. The spray body extends along the arrangement direction of the two second side walls, and the mounting seat is provided with a slide groove extending in the up and down direction. The driving mechanism includes:

[0037] A motor having an output shaft extending along the length direction of the spray body;

[0038] A rotating member is arranged vertically and mounted on the output shaft of the motor, and is provided with a convex portion arranged eccentrically with the output shaft of the motor;

[0039] The actuator is located between the rotating member and the spray body, and includes a connecting ring with an oblate shape for the convex portion to be inserted into the opening surrounded by the connecting ring, a sliding rod connected to the connecting ring, and a connecting rod connected to the connecting ring and consistent with the extension direction of the motor output shaft. The sliding groove is located between the connecting ring and the spray body, and the connecting rod is rotatably connected to the spray body after passing through the sliding groove. The sliding rod extends vertically and is penetrated on the mounting seat. Driven by the rotation of the rotating member, the convex portion is always located in the opening of the connecting ring, thereby driving the actuator and the spray body to move in the up and down directions.

[0040] In order to ensure the reliability of the lifting and lowering of the spray body, the mounting seat, the rotating member and the actuating member are provided in two groups and are arranged at intervals along the length direction of the spray body.

[0041] Compared with the prior art, the advantages of the present invention are that the upper part of the spray body in the cleaning machine is arranged to move close to or away from the first side wall, thereby adjusting the position of the water flow sprayed through the spray hole of the spray body, thereby changing the cleaning position and angle of the washing chamber of the object to be cleaned, strengthening the back and forth cleaning at different positions, facilitating the shedding of residues, and increasing the cleaning area.

[0057] like Figure 2 As shown, the bottom of the main body 11 is provided with a water inlet channel 111 connected to the flow channel 10 near the center, and the water pump assembly 7 is used to pump the water in the drain chamber 401 to the flow channel 10 of the spray arm 1 through the water inlet channel 111. The water pump assembly in this embodiment adopts the water pump assembly in the patent previously applied by the applicant, and will not be described in detail in this embodiment. Figure 3 and Figure 4As shown, the spray arm group 12 includes two sub-spray arms arranged at intervals along the circumference of the main body 11 and extending laterally outward. Each sub-spray arm is provided with at least one slag sweeping hole for spraying downward to sweep slag at a position adjacent to the bottom. Specifically, the bottoms of the two opposite side walls of the sub-spray arms arranged at intervals along the rotation direction have an inclined section 12a that gradually tilts from top to bottom toward the center of the sub-spray arm. The slag sweeping hole is arranged at a position adjacent to the free end of the corresponding inclined section 12a of the sub-spray arm and is connected to the flow channel 10. The above-mentioned slag discharge port 421 is located in the spraying direction of the corresponding slag sweeping hole. The two sub-spray arms of this embodiment are respectively the first spray arm 121 and the 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 area 14. In this embodiment, the rotation trajectory of the free end of the first spray arm 121 is located at the periphery of 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. In addition, the first spray arm 121 and the second spray arm 122 may both be L-shaped, or both be S-shaped, or other shapes.

[0058] like Figure 4 As shown, the slag sweeping holes on the first spray arm 121 are first slag sweeping holes 1211, and each first spray arm 121 has three first slag sweeping holes, and two or more can also be used. The slag sweeping holes on the second spray arm 122 are second slag sweeping holes 1221, and each second spray arm 122 has two second slag sweeping holes 1221, and more than two can also be used. The spraying direction of the first slag sweeping hole 1211 and the spraying direction of the second slag sweeping hole 1221 are both toward the area 14 of the corresponding spray group 12. Specifically, the spraying direction of the first slag sweeping hole 1211 and the spraying direction of the second slag sweeping hole 1221 intersect, and the intersection is located in the area 14 of the spray arm group 12.

[0059] 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 connected to the water flow channel, and the top wall plate has a water spray hole 152 connected to the water flow channel. In addition, a water spray hole 152 is also provided on the top wall of the first spray arm 121. A vertically extending liquid outlet channel 120 is provided on the top surface of at least one of the sub-spray arms in the spray arm group 12. Specifically, each of the first spray arms 121 is provided with a plurality of liquid outlet channels 120 spaced apart along their respective length directions. The liquid inlet hole of the auxiliary spray arm 15 can be selectively installed at one of the liquid outlet channels 120 and connected to the liquid outlet channel 120.

[0060] like Figures 5 to 8 As shown, the spray body 3 is arranged vertically and can be moved up and down on the first side wall 43 of the washing chamber 40, and a gap is left between the first side wall 43. The side wall of the washing chamber 40 arranged adjacent to the first side wall 43 is the second side wall 44. The spray body 3 extends along the arrangement direction of the two second side walls 44, and has a cavity 30 inside. The aforementioned spray body 3 includes an inclined section 31 that gradually inclines from top to bottom toward the first side wall 43 and a vertical section 32 arranged vertically. The inclined section 31 is located above the vertical section 32 and is connected to the bottom edge of the vertical section 32, and is enclosed with the vertical section 32 to form the aforementioned cavity 30. In addition, the aforementioned spray body 3 is provided with a plurality of spray holes 301 spraying into the washing chamber 40 on the wall plate away from the first side wall 43, and the spray holes 301 are connected to the cavity 30. Specifically, the aforementioned inclined section 31 and the vertical section 32 are both distributed with the aforementioned spray holes 301.

When the sprayed water does not act on the inclined section 31, the inclined section 31 of the spray body 3 swings away from the first side wall 43 under the action of its own gravity.

[0061] like Figure 7 As shown, the spray body 3 has a liquid inlet channel 302 connected to the cavity 30 on the wall plate adjacent to the first side wall 43, and a water delivery pipe 47 connecting the drain cavity 401 and the liquid inlet channel 302 is provided on the cleaning box 4. The water delivery pipe 47 is arranged vertically, and the lower end is connected to the drain cavity 401 and is located downstream of the drain cavity 401. The water delivery pipe 47 includes a fixed pipe 471 and a movable pipe section 472 located on the fixed pipe 471 and capable of moving up and down relative to the fixed pipe 471. Along the water flow path, the movable pipe section 472 is located downstream of the fixed pipe 471. The cross section of the water outlet end of the water delivery pipe 47 is circular, that is, the cross section of the end of the movable pipe section 472 is circular, and the liquid inlet channel 302 of the spray body 3 is rotatably connected to the end of the movable pipe section 472. The end of the movable pipe section 472 has a plurality of through holes 470 connecting the cavity 30 and the inner cavity of the movable pipe section 472.

[0062] like Figure 6 , Figures 9 to 11As shown, the spray body 3 drives the movable pipe section 472 to move relative to the fixed pipe 471 along the up-down direction under the drive of the driving mechanism 8, and the power output end of the driving mechanism 8 is connected to the spray body 3. Specifically, both ends of the spray body 3 along the length direction are arranged on the inner wall surface of the corresponding second side wall 44 of the washing chamber 40 through the mounting seat 45, and can also be arranged on the outer wall surface. The aforementioned mounting seat 45 has a accommodating cavity inside, and a slide groove 451 extending along the up-down direction is opened on the side facing the spray body 3. The aforementioned driving mechanism 8 includes a motor 81, a rotating member 82 and an actuator 83. There are two groups of the aforementioned rotating member 82 and the actuator 83, and they are arranged at intervals along the length direction of the spray body 3, and the two rotating members 82 are arranged coaxially. The structures of the two groups of mounting seats, rotating members 82 and actuators 83 are the same, and one group is used as an example for explanation below.

[0063] like Figure 5 As shown, the motor 81 is arranged on the outer wall surface of the second side wall of the washing box 4, and has an output shaft extending along the length direction of the spray body 3; a part of the actuator 83 and the rotating member 82 are located in the accommodating cavity of the mounting seat 45, and the rotating member 82 is arranged vertically and located outside the washing chamber, and is installed on the output shaft of the motor 81. The rotating member 82 has a protrusion 821 arranged eccentrically with the output shaft of the motor 81. Figures 9 to 11 As shown, the aforementioned rotating member 82 includes an annular ring body and a connecting strip arranged inside the annular body. In addition, the rotating member 82 can also be in the form of a turntable, or a strip-shaped structure. The actuator 83 is located between the rotating member 82 and the spray body 3, and includes an oblate connecting ring 831, a sliding rod 832 connected to the connecting ring 831, and a connecting rod 833 connected to the connecting ring 831 and consistent with the extension direction of the output shaft of the motor 81. Among them, the above-mentioned convex portion 821 is inserted into the opening 8311 surrounded by the connecting ring 831; the slide groove 451 is located between the connecting ring 831 and the spray body 3 on the corresponding side, and the connecting rod 833 passes through the slide groove 451 of the mounting seat 45 and is rotatably connected to the spray body 3. There are two aforementioned sliding rods 832, which are coaxially arranged and extend vertically, and are located on the upper and lower sides of the connecting ring 831, and are penetrated at the corresponding position of the mounting seat 45, and can slide up and down relative to the mounting seat 45. When the motor 81 drives the rotating member 82 to rotate, the protrusion 821 is always located in the opening 8311 of the connecting ring 831 , thereby driving the actuating member 83 and the spray body 3 to move in the up and down direction.

[0064] In order to dry the items to be cleaned in the washing chamber, Figure 8As shown, a drying mechanism 9 is provided on the outer wall surface of the cleaning box 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 passage 91 for hot air to be discharged. The exhaust passage 91 includes a vertically arranged vertical passage 911 and a horizontal passage 912 located downstream of the vertical passage 911. The inner peripheral wall of the vertical passage 911 gradually shrinks inward from top to bottom to prevent overflow water from entering the drying mechanism. The above-mentioned fixed pipe 471 has a vertically extending water delivery section 4711, and a blocking member 48 that can move up and down is provided in the inner cavity of the water delivery section 4711, and a connecting port 4712 connected to the exhaust passage 91 is opened on the side wall of the water delivery section 4711, and the connecting port 4712 is located on the moving path of the blocking member 48. A gap for water to pass through is left between the blocking member 48 and the inner peripheral wall of the water delivery section 4711, and 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 located below the connecting port 4712 to open the connecting port 4712. In addition, the blocking member 48 can also be moved downward to be completely located below the connecting port 4712 to open the connecting port 4712. The existence of the blocking member prevents water from flowing into the drying mechanism and affecting the service life of the drying mechanism. The drying mechanism of this embodiment can adopt the structure in the prior art, which will not be described in detail in this embodiment.

[0065] In order to drain the overflow water in time, Figure 8 As shown, a drainage channel 05 connected to the connecting port 4712 is provided below the exhaust channel 91. Specifically, the drainage channel 05 is located below the transverse channel 912 and is connected to the sewer pipe. In order to improve the anti-overflow effect, the drainage pipe 05 partially adopts a curved pipe structure. In order to limit the upper and lower positions of the blocking member 48, an upper stop bar 4713 and a lower stop bar 4714 arranged at intervals are provided in the inner cavity of the water delivery section 4711. The upper stop bar 4713 and the lower stop bar 4714 are connected by a vertically extending connecting bar 4715. The connecting port 4712 is located between the upper stop bar 4713 and the lower stop bar 4714. The upper stop bar 4713, the lower stop bar 4714, the connecting bar 4715 and the side wall where the connecting port 4712 is located form a space for accommodating the blocking member 48.

[0066] like Figure 3As shown, the side spray part 2 is rotatably disposed on the second side wall 44 of the washing chamber 40, and is a straight-line spray arm. The side spray part 2 as a whole is gradually inclined from top to bottom toward the first side wall, and the rotation axis of the side spray part 2 forms an acute angle θ with the horizontal plane A. The side spray part 2 has a water passage 20 inside, and the side spray part 2 is provided with a spray hole 201 on the first wall plate 2a away from the second side wall 44 for spraying into the washing chamber 40, and the spray hole 201 is connected to the water passage 20, and the spray hole 201 sprays downwardly at an angle. The side spray part 2 has a water inlet hole 202 on the second wall plate 2b adjacent to the second side wall 44, which is connected to the water passage 20, and the second wall plate 2b is arranged opposite to the first wall plate 2a.

[0067] like Figure 1 and Figure 3 As shown, at least one water outlet pipe 41 arranged transversely is provided on the second side wall 44 of the washing chamber 40. Specifically, there are at least two water outlet pipes 41, which are arranged at intervals in the up-down direction. In this embodiment, there are three water outlet pipes 41, and more than three or two water outlet pipes can also be used. In addition, the water supply pipe 5 connects the drain chamber 401 and the water outlet pipe 41. Along the fluid flow path, the above-mentioned water outlet pipe 41 is located downstream of the drain chamber 401, so that the water in the drain chamber 401 flows into the water outlet pipe 4 through the water supply pipe 5. The water outlet pipe 41 of this embodiment is partially located in the water supply pipe 5, and a water outlet 411 connecting the water supply pipe 5 and the water outlet pipe 41 is opened on the side wall of the water outlet pipe 41.

[0068] In order to guide the water flow in the drain chamber to the water outlet pipe 41 and the liquid inlet channel 302, an impeller 6 is arranged upstream of the water supply pipe 5 and the water delivery pipe 47. The impeller 6 is installed on the output shaft of the motor of the water pump assembly 7 and is located downstream of the drain chamber 401.

[0069] The water inlet hole 202 of the side spray part 2 is selectively installed on one of the water outlet pipes 41 and communicated with the water outlet pipe 41. In order to realize the detachable installation of the water inlet hole of the side spray part 2 and the water outlet pipe 41, specifically, the water outlet pipe 41 is provided with a baffle 42 that can move back and forth along the flow direction of the water flow in the water outlet pipe 41 (i.e., transversely) to open or close the outlet of the water outlet pipe 41, and a second elastic member that acts on the baffle 42 and makes the baffle 42 always have a tendency to move toward 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 part 2 is provided with a mounting frame 21 that can rotate relative to the side spray part 2. The mounting frame 21 includes a ring-shaped ring part 210 and a connecting rod 212 located in the inner periphery of the ring part 210. The connecting rod 212 has an extension rod 211 extending in a direction away from the side spray part 2, that is, one end of the extension rod 211 is connected to the connecting rod 212. The extension rod 211 in this embodiment 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 part 2. When the side spray part 2 is installed on the water outlet pipe 41, the mounting frame 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 in a direction away from the side spray part 2 to an open outlet state.

[0070] There are many ways to achieve the above-mentioned limitation of the mounting frame 21 and the water outlet pipe 41, which can be a snap-fitting form, a threaded connection form, or other forms. As long as the limitation of both can be achieved, it will not be described in detail in this embodiment.

[0071] 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 arranged at a position adjacent to the bottom of the outer wall surface of the washing box 4. The heating element can be in the form of a heating module, a PTC heating form, or a structure of other heating elements, which will not be described in detail in this embodiment. The water inlet pipe 49 surrounds the periphery of the washing box 4. Specifically, the water inlet pipe 49 is spirally wound on the outer wall of the washing box 4 from top to bottom, and a water outlet is provided on the second side wall of the washing chamber 40 opposite to the spray body 3. The water outlet end of the water inlet pipe 49 of this embodiment is connected to the water outlet of the washing chamber 40 through a connecting pipe 492. When water is introduced in the washing state, the water flow will be preheated in advance when passing through the water inlet pipe, thereby reducing the heating area required for the heating plate at the bottom of the existing washing box during cleaning and heating, improving the working efficiency of the heating plate during the main washing, and using a heating plate with a smaller area, thereby increasing the space utilization rate at the bottom. In addition, when drying, cold water is introduced into the water inlet pipe to wrap the bottom layer of the washing box, which can speed up the condensation rate of hot and humid steam inside the washing box at the bottom, improve the heat exchange efficiency, and further improve the overall drying efficiency inside the washing chamber.

[0072] The drying mechanism in the above embodiment may adopt any drying mechanism in the prior art, and will not be described in detail in this embodiment.

[0073] The working process of the above cleaning machine is as follows:

[0074] During cleaning, the water pump assembly 7 pumps water into the spray device and sprays it upward through the water spray hole 152; and the water in the drain chamber 401 enters the spray body 3 through the water pipe 47 under the drive of the impeller 6, and is sprayed downward at an angle through the spray hole 301 of the spray body 3. Since the inclined section 31 of the spray body 3 is located on the flow path of the water sprayed from the water spray hole 152 of the spray device 01, the inclined section 31 is pushed by the intermittent water flow and swings toward the first side wall 43 relative to the water pipe 47, and then swings in the direction away from the first side wall 43 under its own gravity. During the swinging process of the inclined section 31, the water sprayed obliquely from the spray hole 301 thereon swings continuously, thereby cleaning different positions in the washing chamber back and forth, thereby increasing the cleaning area. When the water in the drain chamber 401 enters the water channel 20 of the side spray component 2 through the water outlet pipe 41 driven by the impeller 6, the side spray component 2 will be driven to rotate relative to the mounting frame 21, and water will be sprayed into the washing chamber 40 through the spray hole 201. At this time, the water sprayed from the side spray component 2 flows horizontally and obliquely downward; in this way, the horizontally oblique downward water flow and the vertically upward spray water flow at the bottom intersect with each other, so that the vertical and horizontal staggering of the cleaning water flow is realized, thereby improving the overall cleaning effect of the objects to be cleaned.

[0075] During drying, part of the drying airflow enters the spray body 3 through the exhaust channel 91 and the water delivery section 4711, and is sprayed out through the spray hole 301, thereby performing a diving up and down circulation drying on the objects to be cleaned, while the other part flows into the drain chamber 401 through a fixed pipe, thereby drying the inside of the drain chamber. In addition, the water pump assembly can drive the spray device to rotate, and the drying airflow is sprayed out through the spray hole, accelerating the diffusion of the drying airflow, and achieving targeted cleaning of the positions at the bottom of the cleaning box that are prone to water accumulation. In this way, the combination of up and down circulation flushing and drying and bottom rotation drying can achieve a three-dimensional drying effect of the cleaning box.
