When the utility model is in use, the impeller assembly draws water from the water collecting chamber of the first spray arm, and the water flows through the first flow channel and the second flow channel and then is dispersed and sprayed out for lower layer spraying; at the same time, the water in the water collecting chamber also enters the second spray arm above it through the output channel for upper layer spraying, thereby realizing double layer spraying. The cleaning machine of the above double layer spraying system expands the spraying range, which is conducive to eliminating cleaning dead corners and improving the cleaning effect, but the spraying angle cannot be changed, resulting in a limited cleaning range and prone to cleaning dead corners; and the first spray arm and the second spray arm are always located horizontally in the box, that is, they are in the same position in the working state and the non-working state, so when not in use, they also occupy more space in the box.

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

[0005] The first technical problem to be solved by the present invention is to provide a spray system with a retractable first spray arm 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 technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a spray system, comprising:

[0016] Preferably, the flip member is disposed in the storage space of the rack, and the flip member is detachably mounted on the rack, so that the height of the flip member can be adjusted according to actual needs.

[0017] The flip member may be in the form of a frame structure or a connecting plate. However, from the perspective of increasing the space for placing the objects to be cleaned and improving the support reliability of the first spray arm, preferably, the flip member is in the form of a frame structure, and the first spray arm is detachably mounted on the corresponding rod of the flip member. In this way, the setting position of the first spray arm can be adjusted according to actual needs.

[0018] There are many structural forms of the first spray arm, which can adopt a straight-line spray structure, a herringbone shape, or other structural forms. Preferably, the first spray arm includes a main spray arm and a sub-spray arm arranged on the main spray arm, the water inlet channel is located on the main spray arm, there are at least two sub-spray arms, and they are arranged at intervals along the length direction of the main spray arm, and the water outlet is opened at the position corresponding to the sub-spray arm.

[0019] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a cleaning machine with the above-mentioned spray system, characterized in that it also includes a cleaning box with a washing chamber inside and a second spray arm arranged at a position near the bottom of the washing chamber, the spray system is located in the washing chamber and above the second spray arm, the second spray arm has a flow channel inside, and the top wall and / or side wall of the second spray arm are specifically connected to the spray hole of the flow channel.

[0020] Preferably, when the flip member is at least in a transverse arrangement state, the water inlet channel is in fluid communication with the flow channel, so that the first spray arm can spray water.

[0021] Preferably, the cleaning machine further comprises a water conduit having a water outlet pipe section, and when the first spray arm is in a transverse arrangement state, the first spray arm can be in fluid communication with the water outlet pipe section.

[0022] Preferably, the side wall of the cleaning box adjacent to the flip member is the first side wall, and the water pipe connected to the flow channel fluid is arranged on the outer side of the first side wall of the cleaning box, and the water pipe has the transversely arranged water outlet pipe section, and the first side wall of the cleaning box is provided with a mounting hole for the water outlet pipe section to pass through, and when the first spray arm is in a transversely arranged state, the water inlet channel extends along the length direction of the water outlet pipe section and is connected to the water outlet pipe section fluid.

[0023] In order to ensure that the water outlet pipe section is always connected to the water inlet channel during the flipping process of the flipping member, a movable sleeve that can move back and forth along the length direction of the water inlet channel is installed at the water inlet end of the water inlet channel. The free end of the movable sleeve has a sealing ring, and also includes an elastic member that enables the movable sleeve to always have a tendency to move toward the water outlet pipe section so that the sealing ring and the peripheral side of the mounting hole of the first side wall are against each other. The elastic member acts on the movable sleeve.

[0024] Preferably, when the flip member is flipped to be in a vertical arrangement state, the water outlet pipe section and the water flow channel of the first spray arm are not connected to each other.

[0037] The present invention is further described in detail below with reference to the accompanying drawings.

[0038] Embodiment 1:

[0039] like Figures 1 to 8The first preferred embodiment of the present invention is shown in FIG. The cleaning machine of this embodiment is used to clean dishes or fruits and vegetables.

[0040] The above-mentioned cleaning machine includes a cleaning box 1, a housing 12, a spray system, a second spray arm 3, a movable sleeve 7, a water pump mechanism 8 and a water guide pipe 9. The cleaning box 1 includes a box body 1a with an open top and a door body (not shown) covering the open top of the box body 1a. The box body 1a and the door body enclose a washing chamber 10. The bottom of the washing chamber 10 is concave in the vicinity of the center to form a drain chamber 101. Figure 6 As shown, the drain chamber 101 is covered with a filter plate 13 , and filter holes are formed on the filter plate 13 .

[0041] The above-mentioned spray system is arranged in the washing chamber 10, and the spray system includes a storage rack 2 and a first spray arm 5. The storage rack 2 of this embodiment is a bowl rack and has a storage space 20 with an open top. Figure 6 As shown, the filter plate 13 is provided with an assembly hole near the center, the upper part of the shell 12 is installed at the assembly hole, and the lower part of the shell 12 is located in the drain chamber 101. The second spray arm 3 is arranged near the bottom of the washing chamber 10 and is located below the spray system. The second spray arm 3 has a flow channel 30 inside, and the top wall of the second spray arm 3 is specifically connected to the spray hole 301 of the flow channel 30; and the bottom of the second spray arm 3 has a water inlet channel 302 near the center. The shell 12 has an inner cavity 120 inside, and the water inlet channel 302 of the second spray arm 3 can be rotatably arranged on the shell 12, and the inner cavity 120 of the shell 12 is connected to the flow channel 30 through the water inlet channel 302.

[0042] like Figure 1 and Figure 2 As shown, the flip member 4 is arranged in the storage space 20 inside the rack 2, so that the second spray arm 3 is located below the rack 2. In this embodiment, the flip member 4 is arranged on the left side wall of the rack 2, and is a frame structure composed of cross-arranged rods. The aforementioned flip member 4 is arranged to be able to rotate up and down relative to the rack 2; specifically, the side edge of the flip member 4 can be rotatably and positionally arranged on the side rod of the rack 2. When the flip member 4 is flipped to be in a vertical arrangement state, the side edge of the flip member 4 is the lower edge 41 of the flip member 4. There are many ways to realize the rotation and positioning of the flip member 4, and any structure in the prior art can be adopted, which will not be described in detail in this embodiment. In addition, the above-mentioned flip member 4 can be detachably installed on the rack 2, so that the height of the flip member 4 can be adjusted according to actual needs. For details, see Figure 2 and Figure 5 shown.

[0043] like Figure 1 and Figure 2 As shown, the first spray arm 5 is disposed on the flip member 4 and arranged along the flip member 4. Thus, when the flip member 4 flips relative to the storage rack 2, the first spray arm 5 rotates with the flip member 2. Since the first spray arm 5 is arranged along the flip member 4, Figure 5 When the flip member is flipped to the vertical state, the first spray arm 5 is arranged vertically. At this time, the flip member and the first spray arm 5 are folded on the inner wall of the cleaning box, avoiding the occupation of the internal space of the rack and improving the utilization rate of the internal space of the rack; Figure 1 and Figure 2 As shown, when the flip member 4 is flipped to the horizontal arrangement state, the first spray arm 5 is arranged horizontally. Specifically, the first spray arm 5 can be detachably mounted on the corresponding rod body of the flip member 4. The first spray arm 5 has a water flow channel 50 inside, and the first spray arm 5 has a water outlet hole 521 and a water inlet channel 511 connected to the water flow channel 50. A buckle is provided on the wall plate where the water outlet hole 521 of the first spray arm 5 is located, and the first spray arm 5 is mounted on the rod body of the flip member 4 through the buckle. When the flip member 4 is flipped to the horizontal arrangement state, the first spray arm 5 is located under the flip member 4, the water outlet hole 521 is located on the top wall plate of the first spray arm 5, and the water outlet direction of the water outlet hole 521 is toward the flip member 4. In addition, after the first spray arm 5 is removed from the flip member 4, the first spray arm 5 can be installed on the upper surface of the flip member 4. In this way, when the flip member 4 is flipped to a horizontal arrangement state, the first spray arm 5 is located above the flip member 4. At this time, the water outlet is located on the bottom wall plate of the first spray arm 5, so that the objects to be cleaned on the rack can be cleaned. Figure 7As shown, the first spray arm 5 includes a main spray arm 51 and a sub-spray arm 52 arranged on the main spray arm 51, the water inlet channel 511 is located on the main spray arm 51, and the sub-spray arm 52 is formed by the extension of the local side wall of the main spray arm 51. In this embodiment, there are at least two sub-spray arms 52, and they are arranged at intervals along the length direction of the main spray arm 51. The cross-section of the sub-spray arm 52 of this embodiment is basically semicircular, and there are three of them. In addition, four or more sub-spray arms can be set. In addition, each sub-spray arm 52 is provided with a rotating wheel 53 that rotates under the impetus of the water flow. Specifically, the sub-spray arm 52 is provided with a wall plate opposite to the opening 55, and a ring-shaped boss 56 is convexly provided. The rotating wheel 53 can be rotatably limited on the boss 56. The rotating wheel 53 is used to direct the water flow toward the water outlet 521 and the spray ball 54. The rotation axis of the rotating wheel 53 extends along the axis of the water outlet 521. In this embodiment, there are multiple water outlet holes 521, and some of them are arranged at intervals along the length direction of the main spray arm 51. Each sub-spray arm 52 is correspondingly provided with at least one of the aforementioned water outlet holes 521. In addition, the first spray arm 5 is provided with an opening 55 on the wall panel where the water outlet hole 521 is located. The opening 55 is provided at a position corresponding to the sub-spray arm 52, and a rotatable and spherical spray ball 54 is installed at the opening 55. The spray ball 54 is provided with a water spray channel 541 connected to the water flow channel 54. Figure 8 As shown, a water hole 561 is provided on the side wall of the boss 56 to connect the water flow channel 50 and the water spray channel of the spray ball 54. Thus, when the first spray arm 5 is placed horizontally, after the water flows into the water inlet channel 511 of the first spray arm 5, the three rotating wheels 53 are driven to rotate, and the water flows into the bottom of the rotating wheels 53, and under the action of the rotating wheels 53, the water flows toward the water outlet hole 521 and the water spray channel 541 of the spray ball 54. The rotation of the rotating wheels 53 can make the water flow sweep in an umbrella shape.

[0044] like Figure 4 and Figure 7 As shown, the water inlet channel 511 is opened on the side wall of the first spray arm 5. Figure 3 and Figure 4As shown, when the flip member 4 is flipped to be in a transverse arrangement state, the water inlet channel 511 can be in fluid communication with the flow channel 30. Specifically, the side wall of the cleaning box 1 adjacent to the flip member 4 is the first side wall 11. The first side wall 11 in this embodiment is the left side wall of the cleaning box. In addition, it can also be the right side wall, the front side wall or the rear side wall. The outer side of the first side wall 11 of the aforementioned cleaning box is provided with a pipeline in fluid communication with the inner cavity 120 of the shell 12. The pipeline in this embodiment is a water guide pipe 9. The aforementioned water guide pipe 9 has a transversely arranged water outlet pipe section 91. The first side wall 11 of the cleaning box 1 is provided with a mounting hole 111 for the water outlet pipe section 91 to pass through. When the first spray arm is flipped with the flip member 4 to be in a transverse arrangement state, the water inlet channel 511 extends along the length direction of the water outlet pipe section 91 and can be in fluid communication with the water outlet pipe section 91. When the first spray arm 5 is turned over with the turning member 4 to be in a vertical arrangement state, the water outlet pipe section 91 is connected to the washing chamber 10, and the water flow channel 50 of the first spray arm 5 is not connected to the flow channel 30. Specifically, the water inlet end of the water inlet channel 511 is installed with a movable sleeve 7 that can move back and forth along the length direction of the water inlet channel 511, and the free end (left end) of the movable sleeve 7 has a sealing ring 71. The end (i.e., the right end) of the movable sleeve 7 away from the sealing ring 71 is partially located in the water inlet channel 511, and the elastic member is a spring 01 located between the movable sleeve 7 and the water inlet channel 511, and the expansion direction of the spring 01 is along the movement direction of the movable sleeve 7. In this way, the aforementioned spring 01 acts on the movable sleeve 7 in the energy storage state, and makes the movable sleeve 7 always move toward the water outlet pipe section 91, and then makes the sealing ring 71 of the movable sleeve 7 have a tendency to abut against the peripheral side of the mounting hole 111 of the first side wall 11. In this way, as the flipping member is flipped at different angles, the sealing ring 71 of the movable sleeve 7 always abuts against the peripheral side of the mounting hole 111 of the inner wall surface of the first side wall 11, thereby achieving the sealing between the movable sleeve 7 and the inner wall surface of the first side wall 11, and then achieving the connection between the internal flow channel of the movable sleeve 7 and the water outlet pipe section 91. That is, according to the actual rotation angle of the flipping member 4 (such as horizontal arrangement, and any position between the horizontal and vertical directions), the gaps of different sizes between the flipping member 4 and the first side wall can be adapted, and finally the movable sleeve is sealed and connected with the first side wall, that is, in other states of the above-mentioned flipping member 4 except when it is in the vertical state, the water flow channel of the first spray arm is always in a connected state with the flow channel of the second spray arm.

[0045] In order to prevent the movable sleeve 7 from being separated from the water inlet channel, the movable sleeve 7 is slidably limited on the water inlet channel. Figure 4As shown, the movable sleeve 7 has a slot 72 on the outside of its internal channel, the slot 72 extends along the movement direction of the movable sleeve 7 and is open at one end (right end) away from the sealing ring 71, the water inlet end of the water inlet channel 511 is located in the slot 72, and a limiting structure for limiting the water inlet channel 511 from escaping from the slot 72 is matched and arranged between the corresponding wall plates of the water inlet channel 511 and the slot 72. The limiting structure includes a convex portion 5111 arranged on the outer peripheral wall of the water inlet channel 511 and a flange 721 arranged at a position adjacent to the right end of the inner side wall of the slot 71, the convex portion 5111 is located on the movement path of the flange 721, when the movable sleeve 7 moves to the leftmost position (that is, the sealing ring is in the state of being farthest from the water inlet end of the water inlet channel), the convex portion 5111 is located on the left side of the flange 721, and the convex portion 5111 abuts against the flange 721.

[0046] like Figure 6 As shown, the water pumping mechanism 8 can reliably pump the water in the drain cavity to the water inlet end of the water guide pipe 9 and the water inlet channel 302, and the water pumping mechanism 8 is partially located in the inner cavity 120 of the housing 12. Specifically, the water pumping mechanism 8 includes a motor 81 and an impeller assembly 82, the motor 81 is located below the housing 12, and has an output shaft extending upward and partially located in the inner cavity 120 of the housing 12, and the impeller assembly 82 is located in the inner cavity 120 of the housing 12 and is mounted on the output shaft of the motor 81. When the motor 81 is working, it drives the impeller assembly 82 to rotate, pumping a part of the water into the flow channel 30 of the second spray arm 3, and ejecting it from the spray hole 301 of the second spray arm 3. When the first spray arm 5 is in a horizontal arrangement state, the other part of the water passes through the water guide pipe 9 and flows into the water flow channel of the first spray arm 5 through the movable sleeve, and finally flows out through the water outlet hole 521 and the water spray channel 541. The setting of the spray ball can change the spray angle and perform spray cleaning on different positions.

[0047] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0048] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.

[0049] Embodiment 2:

[0050] like Figures 9 to 11 As shown, it is the second preferred embodiment of the present invention. The only difference between this embodiment and the above-mentioned embodiment 1 is that: during the rotation of the first spray arm 5 with the flip member 4, the water flow channel 50 of the first spray arm 5 is always in fluid communication with the flow channel 30 of the second spray arm 3. The pipeline of this embodiment is a connecting pipe 6 located inside the cleaning box, that is, the upper part of the connecting pipe 6 is located in the washing chamber 10, and the lower part is located in the drain chamber 101. The water inlet channel 511 of the first spray arm 5 is always connected to the connecting pipe 6 through a bendable flexible tube 61. The aforementioned flexible tube 61 is a corrugated tube, which can be made of silicone or other materials. When the first spray arm 5 is flipped to a vertical arrangement state with the flip member 4, at this time, the water outlet 521 faces the inner wall surface of the first side wall of the cleaning box 1, and the water flow sprayed through the water outlet 521 can flush the first side wall.

[0051] The sub-spray arm 52 of the first spray arm 5 of the present embodiment is basically an L-shaped strip structure. The water outlet 521 on the first spray arm 5 is located on the sub-spray arm 52 , and no opening is provided on the sub-spray arm 52 .

[0052] When the motor 81 is working, it drives the impeller assembly 82 to rotate, pumping a part of the water into the flow channel 30 of the second spray arm 3, and ejecting it from the spray hole 301 of the second spray arm 3. When the first spray arm 5 is in a horizontal arrangement state, another part of the water flows into the water flow channel of the first spray arm 5 through the connecting pipe 6 and the flexible pipe 61, and finally flows out through the water outlet 521.
