Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a washing machine for washing dishes, vegetables or fruits. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Dishwashers on the market are generally divided into three types: tabletop, cabinet, and tank. Among them, tabletop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] At present, the structure of the relatively mature water tank type cleaning machine on the market is mainly as described in the Chinese patent "Water Tank Type Cleaning Machine" (application number: CN201310750968.1) with the authorization announcement number CN104224074B, that is, it includes a box body forming a washing space, the box body includes a water tank body and a cover plate rotatably connected to the water tank body, the bottom of the water tank body has a concave drain area at least in the central part, and the drain area is provided with a water pump that pumps the water in the drain area out to the washing space above the drain area, the drain area is covered with a drain plate with drain holes, and a rotating spray arm connected to the water pump fluid and having a water outlet hole is arranged above the drain plate. By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The sink body of the above-mentioned existing sink-type cleaning machine is made of stainless steel material, and the processing methods are mainly welding and drawing. Among them, for the welding process, due to the large welding deformation of stainless steel materials, it is difficult to control the dimensional accuracy of the sink, which limits the overall shape of the sink body, resulting in a single structure of the sink body, which in turn restricts the development of more functional structures of the sink-type cleaning machine. In addition, the welding process has extremely high requirements for the welding mold, low welding efficiency and high cost; for the drawing process, the deformation limit of the stainless steel material directly limits the drawing depth of the sink. The sink drawn by the drawing process generally has a depth less than the opening width of the sink. At present, it is difficult for the processes around the world to achieve a drawing depth greater than the opening width of the sink body, which causes the sink to occupy a larger installation space in the kitchen during installation and greatly limits the washing space of the sink. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning machine which adopts a tank body combining plastic and metal so as to deepen the tank body and reduce the production cost in view of the current status of the prior art.

[0006] Another technical problem to be solved by the present invention is to provide a cleaning machine capable of preventing deformation of a plastic tank body, improving the cleaning effect and the condensation effect after cleaning, in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, including a sink body with a washing chamber, characterized in that: the sink body is made of plastic material, and also includes a first metal reinforcement, a second metal reinforcement and a third metal reinforcement, the first metal reinforcement is arranged on the inner wall surface of the upper part of the sink body, the second metal reinforcement is sleeved on the outer periphery of the sink body, and the third metal reinforcement is arranged on the inner wall surface of the lower part of the sink body.

[0008] Preferably, a guide strip extending up and down is convexly provided on the inner wall surface of the first metal reinforcement member, which can guide the condensed water downward, which is conducive to accelerating the condensation of water.

[0009] In order to facilitate installation, a first accommodating groove arranged along the circumferential direction is opened on the inner wall surface of the upper part of the water tank body, and the first metal reinforcement is arranged in the first accommodating groove. This structure facilitates the positioning and installation of the first metal reinforcement.

[0010] Preferably, the first metal reinforcement is formed as an annular plate extending up and down in the first accommodating groove, the upper edge of the annular plate contacts the upper edge of the first accommodating groove, and the lower edge of the annular plate contacts the lower edge of the first accommodating groove.

[0011] Further preferably, the upper edge of the annular plate is bent into the first accommodating groove to form a first U-shaped structure with an opening facing downward, and the outer side of the first U-shaped structure contacts the inner wall of the first accommodating groove, and the lower edge of the annular plate is bent into the first accommodating groove to form a second U-shaped structure with an opening facing upward, and the outer side of the second U-shaped structure contacts the inner wall of the first accommodating groove, and the annular plate and the first and second U-shaped structures on the annular plate together form a first cavity with the inner wall of the first accommodating groove. Since the hot water is mainly sprayed onto the inner wall of the middle and upper part of the water tank body after being sprayed out by the spray arm, and the hot steam rises to the top of the water tank body, the above-mentioned first cavity can improve the thermal insulation performance of the lower part of the water tank body and save energy consumption on the one hand, and on the other hand, it can also play a sound insulation effect to a certain extent.

[0012] Preferably, the outer wall of the annular plate is inwardly concave to form a concave area corresponding to the guide strip. The convex inner and concave outer structure of the guide strip greatly enhances the elasticity of the annular plate. When the ultrasonic cleaning device of the cleaning machine is activated, it forms a strong resonance with the ultrasonic wave to improve the cleaning effect.

[0013] Preferably, a reinforcing rib is provided on the outer peripheral wall of the water tank body in the area corresponding to the first containing groove. This structure is provided to improve the rigidity of the upper part of the water tank body to avoid deformation of the top of the water tank body caused by high temperature.

[0014] Preferably, the open portion of the water tank body is made of metal at least at the position in contact with the installation plane, and the water tank body portion below is made of plastic. Since the top edge of the water tank body is generally used as the load-bearing position during installation of the current water tank body, the above structure is used to improve the stability of the installation of the water tank body.

[0015] In order to facilitate installation and improve stability after installation, a metal assembly frame for installation and load-bearing is provided on the open periphery of the water tank body.

[0016] Preferably, the open edge extends outward to form a shelf that can be placed on the installation plane, and the metal assembly frame is arranged around the open periphery of the sink body, and its cross section has at least a Z-shaped portion, wherein the lower side of the Z-shape is arranged under the shelf, the vertical side of the Z-shape is arranged outside the periphery of the shelf, and the upper side of the Z-shape gradually extends outward away from the shelf. The upper side of the Z-shaped portion of the metal assembly frame has an outer vertical side that is bent downward at the extended end, and the lowermost end of the outer vertical side is flush with the lower side of the Z-shaped portion. This further improves the stability after installation.

[0017] Preferably, the inner wall of the first metal reinforcement is flush with the inner wall surface of the water tank body.

[0018] In the above schemes, an ultrasonic generator is provided at the bottom of the water tank body. This structure can effectively improve the cleaning effect, and the first metal reinforcement member provided on the upper part of the plastic tank body can resonate with the ultrasonic generator to further improve the ultrasonic cleaning effect.

[0019] Preferably, the second metal reinforcement includes a main body and a locking rod, the main body is formed into a U shape and is sleeved on the outer periphery of the lower middle part of the sink body, the two ends of the main body extend out of the corresponding outer walls of the sink body, and the locking rod is connected between the two ends of the main body to lock the main body on the sink body.

[0020] For easy assembly, the first end of the body is provided with a first mounting hole, and correspondingly, the second end of the body is provided with a second mounting hole, the first end of the locking rod is limited outside the first end of the body, and the second end of the locking rod passes through the first mounting hole and the second mounting hole and is locked outside the second end of the body by a nut. The middle and lower parts of the two oppositely arranged side walls of the water tank body are provided with sliding grooves through which the two ends of the body can slide.

[0021] In order to facilitate installation, a second accommodating groove arranged along the circumferential direction is opened on the inner wall surface of the lower part of the water tank body, and the third metal reinforcement is arranged in the second accommodating groove. This structure facilitates the positioning and installation of the third metal reinforcement.

[0022] Preferably, the third metal reinforcement comprises a first assembly ring, a second assembly ring and a connecting arm, wherein the first assembly ring is arranged near the upper edge of the second receiving groove, the second assembly ring is arranged near the lower edge of the second receiving groove, and the connecting arm is a plurality of arms that are spaced apart and vertically connected between the first assembly ring and the second assembly ring. Alternatively, the third metal reinforcement is formed as an annular plate extending up and down in the second receiving groove, the upper edge of the annular plate contacts the upper edge of the second receiving groove, and the lower edge of the annular plate contacts the lower edge of the second receiving groove. As the preferred structure of the third metal reinforcement, the above two structures can realize two basic functions: first, since the cleaning machine often needs to alternate hot water and cold water for cleaning during the cleaning process, and the deformation degree caused by cold water and hot water to the plastic tank body is different, and when hot water is used for cleaning, the hot steam rises to the upper part of the tank body, and when cold water is used for cleaning, the cold water is generally located at the bottom of the tank body. Therefore, the deformation caused by cold shrinkage at the bottom of the tank body is the largest. The above third metal reinforcement structure can support the lower part of the plastic tank body and prevent the lower part of the tank body from internal deformation due to cold shrinkage; second, an ultrasonic sounding device is often provided in the tank-type cleaning machine, and the above third metal reinforcement structure can resonate with the ultrasonic sounding device to enhance the ultrasonic cleaning effect.

[0023] Preferably, the third metal reinforcement is formed as an annular plate extending up and down in the second accommodating groove, the upper edge of the annular plate contacts the upper edge of the second accommodating groove, and the lower edge of the annular plate contacts the lower edge of the second accommodating groove.

[0024] Further preferably, the upper edge of the annular plate is bent into the second accommodating groove to form a fourth U-shaped structure with an opening facing downward, and the outer side of the fourth U-shaped structure contacts the inner wall of the second accommodating groove, and the lower edge of the annular plate is bent into the second accommodating groove to form a fifth U-shaped structure with an opening facing upward, and the outer side of the fifth U-shaped structure contacts the inner wall of the second accommodating groove, and the annular plate and the fourth and fifth U-shaped structures on the annular plate together form a third cavity with the inner wall of the second accommodating groove. Since hot water will fall back to the lower part of the water tank body after being sprayed out by the spray arm and stay in the lower part of the water tank body for a certain period of time, the above-mentioned third cavity can improve the thermal insulation performance of the lower part of the water tank body and save energy consumption on the one hand, and on the other hand, it can also play a sound insulation effect to a certain extent.

[0025] Preferably, a plurality of protrusions arranged at intervals are provided on the inner wall surface of the annular plate. The protrusions are integrally formed with the annular plate, and the positions corresponding to the protrusions on the outer wall surface of the annular plate are recessed toward the washing chamber. With the above structure, the protrusions can further strengthen the strength of the lower part of the water tank body. At the same time, the protrusions of the inner convex and outer concave structure greatly enhance the elasticity of the annular plate and form a stronger resonance with the ultrasonic wave, further improving the cleaning effect.

[0026] Preferably, the outer peripheral wall of the lower part of the water tank body corresponding to the second accommodating groove is arranged to protrude outward so that the thickness of the lower part of the water tank body is consistent with the thickness of the upper part of the water tank body. This structure can ensure that the water tank body has good firmness and stability.

[0027] Compared with the prior art, the advantages of the present invention are as follows: the present invention adopts plastic to manufacture the water tank body, which has strong plasticity, is convenient to deepen the depth of the water tank body as needed, and also greatly reduces the production cost; the present invention arranges a first metal reinforcement on the inner wall surface of the upper part of the water tank body, when the hot water cleaning is completed, a large amount of steam will be retained at the top of the washing chamber, the above-mentioned first metal reinforcement can accelerate the condensation of steam, at the same time, the first metal reinforcement improves the strength of the upper part of the plastic tank body, prevents the upper part of the water tank body from being deformed by heat, and can also resonate with the ultrasonic sound-generating device in the water tank cleaning machine to improve the ultrasonic cleaning effect, the second metal reinforcement at the lower part of the water tank body can prevent the lower part of the water tank body from being deformed by heat or cold, on the other hand, can reduce the noise generated by the water flow hitting the inner wall of the water tank body, and accelerate the condensation speed of high-temperature steam, accelerate the drying speed in the washing chamber, and improve the cleaning effect; the present invention arranges a third metal reinforcement on the inner wall surface of the lower part of the water tank body, the third metal reinforcement can prevent the water tank body from being deformed by heat or cold, at the same time, can also resonate with the ultrasonic sound-generating device at the bottom of the water tank cleaning machine to improve the ultrasonic cleaning effect.

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

[0038] Embodiment 1:

[0039] like Figures 1 to 7 As shown, the washing machine of this embodiment is a water tank type washing machine, comprising a water tank body 1 having a washing cavity 10, the water tank body 1 needs to be installed on a cabinet countertop 100 for use, and the cabinet countertop 100 is provided with an installation opening 101 for installing the water tank body 1. The top of the water tank body 1 has an opening 11 connected to the washing cavity 10.

[0040] The bottom of the water tank body 1 of this embodiment is provided with a water pump 6 which can lift water from the bottom of the water tank body 1 and spray it upward through the spray arm 5. The bottom of the water tank body 1 is provided with an ultrasonic generator 4, which can effectively improve the cleaning effect.

[0041] The open portion 11 of the sink body 1 of this embodiment is made of metal at least at the position in contact with the cabinet countertop 100, and the sink body 1 portion below it is made of plastic. Considering that the plastic sink body 1 has a low load-bearing capacity, a metal assembly frame 2 for installation and load-bearing is provided at the periphery of the open portion 11 of the sink body 1. The edge of the open portion 11 extends outward to form a shelf 12 that can be placed on the cabinet countertop 100. The metal assembly frame 2 is arranged around the periphery of the open portion 11 of the sink body 1, and its cross section has at least a Z-shaped part, wherein the lower side 21 of the Z-shape is arranged under the shelf 12, the vertical side 20 of the Z-shape is arranged outside the periphery of the shelf 12, and the upper side 22 of the Z-shape gradually extends outward away from the shelf 12. The upper side 22 of the Z-shaped part of the metal assembly frame 2 has an outer vertical side 23 bent downward at the extended end, and the lower end of the outer vertical side 23 is flush with the lower side 21 of the Z-shaped part. This structure can effectively improve the safety and stability of installation.

[0042] In this embodiment, a first metal reinforcement 3' arranged along the circumference of the water tank body 1 is provided on the inner wall surface of the upper part of the water tank body 1. In order to facilitate installation, a first circumferentially arranged first receiving groove 13 is opened on the inner wall surface of the upper part of the water tank body 1, and the first metal reinforcement 3' is arranged in the first receiving groove 13. After assembly, the inner wall of the first metal reinforcement 3' is flush with the inner wall surface of the water tank body 1. This structure facilitates the positioning and installation of the first metal reinforcement 3'. A reinforcing rib 7 is provided on the outer peripheral wall of the water tank body 1 in the area corresponding to the first receiving groove 13. The reinforcing rib 7 has first reinforcing strips 71 arranged at intervals and extending up and down, and second reinforcing strips 72 connected to the lower end of each first reinforcing strip 71 along the circumferential direction. The provision of this structure can improve the rigidity of the upper part of the water tank body 1, and work together with the first metal reinforcement 3' to prevent deformation of the top of the water tank body 1 due to high temperature.

[0043] Specifically, the first metal reinforcement 3' is formed as an annular plate extending up and down in the first receiving groove 13, the upper edge of the annular plate contacts the upper edge of the first receiving groove 13, and the lower edge of the annular plate contacts the lower edge of the first receiving groove 13. The upper edge of the annular plate is bent into the first receiving groove 13 to form a first U-shaped structure 31' with an opening facing downward, the outer side of the first U-shaped structure 31' contacts the inner wall of the first receiving groove 13, and the lower edge of the annular plate is bent into the first receiving groove 13 to form a second U-shaped structure 32' with an opening facing upward, the outer side of the second U-shaped structure 32' contacts the inner wall of the first receiving groove 13, and the annular plate and the first U-shaped structure 31' and the second U-shaped structure 32' on the annular plate together form a first cavity 30' with the inner wall of the first receiving groove 13. A plurality of guide strips 33' extending up and down at intervals are convexly provided on the inner wall surface of the first metal reinforcement 3'. The outer wall surface of the first metal reinforcement 3' is inwardly concave at the guide strip 33'. The convex inner and concave outer structure of the guide strip 33' greatly enhances the elasticity of the annular plate. When the ultrasonic cleaning device 4 of the cleaning machine is activated, it forms a strong resonance with the ultrasonic wave to improve the cleaning effect. Since the hot water is mainly sprayed onto the inner wall of the upper middle part of the water tank body 1 after being sprayed through the spray arm 5, and the hot steam rises to the top of the water tank body 1, the above-mentioned first cavity 30' can improve the thermal insulation performance of the lower part of the water tank body 1 and save energy consumption on the one hand, and on the other hand, it can also play a sound insulation effect to a certain extent.

[0044] In this embodiment, a second metal reinforcement 3 is also sleeved on the outer periphery of the middle and lower part of the water tank body 1. Specifically, the second metal reinforcement 3 of this embodiment includes a body 31 and a locking rod 32. The body 31 is formed into a U shape and sleeved on the outer periphery of the middle and lower part of the water tank body 1. The two ends of the body 31 extend out of the corresponding outer walls of the water tank body 1. The locking rod 32 is connected between the two ends of the body 31 so as to lock the body 31 on the water tank body 1. In order to facilitate assembly, a first mounting hole 311 is opened at the first end of the body 31, and correspondingly, a second mounting hole 312 is opened at the second end of the body 31. The first end of the locking rod 32 is limited to the outer side of the first end of the body 31 by a limiting block 321, and the second end of the locking rod 32 passes through the first mounting hole 311 and the second mounting hole 312 and is locked to the outer side of the second end of the body 31 by a nut 322. A sliding groove 13' is opened at the middle and lower part of the two oppositely arranged side walls of the water tank body 1, through which the two ends of the body 31 can slide. When the sink body 1 is made of plastic, considering the angle and height of the water sprayed by the spray arm 5 during the cleaning process of the cleaning machine, the lower and middle part of the sink body 1 is the area that directly contacts the water output of the spray arm 5 the most. Therefore, this part is most likely to be deformed due to heat. Enclosing the above-mentioned second metal reinforcement 3 outside the sink body 1 can effectively reduce the deformation of the sink body 1 caused by heat; at the same time, the water output of the spray arm 5 will produce a large noise when hitting the inner wall of the sink body 1, and the above-mentioned second metal reinforcement 3 can also play a role in reducing the noise; in addition, since the cleaning machine generally adopts the method of alternating hot and cold water for cleaning, a large amount of steam will remain in the washing chamber 10 after the hot water cleaning is completed. The plastic material is not conducive to the condensation of steam. After adopting the above-mentioned second metal reinforcement 3, it is conducive to the rapid condensation of high-temperature steam, thereby increasing the drying speed inside the sink body 1, which is beneficial to the cleaning process.

[0045] In this embodiment, a third metal reinforcement 8 arranged along the circumference of the water tank body 1 is provided on the inner wall surface of the lower part of the water tank body 1. In order to facilitate installation, a second accommodating groove 14 arranged along the circumference is opened on the inner wall surface of the lower part of the water tank body 1, and the third metal reinforcement 8 is arranged in the second accommodating groove 14. After assembly, the inner wall of the third metal reinforcement 8 is flush with the inner wall surface of the water tank body 1. This structure facilitates the positioning and installation of the third metal reinforcement 8. The outer peripheral wall of the lower part of the water tank body 1 corresponding to the second accommodating groove 14 is arranged to protrude outward so that the thickness of the lower part of the water tank body 1 is consistent with the thickness of the upper part of the water tank body 1. This structure can ensure that the water tank body 1 has good firmness and stability.

[0046] Specifically, the third metal reinforcement 8 of this embodiment includes a first assembly ring 81, a second assembly ring 82 and a connecting arm 83. The first assembly ring 81 is arranged near the upper edge of the second accommodating groove 14, and the second assembly ring 82 is arranged near the lower edge of the second accommodating groove 14. The connecting arm 83 is a plurality of and spaced apart vertically connected between the first assembly ring 81 and the second assembly ring 82. The third metal reinforcement 8 can realize two basic functions: first, since the cleaning machine often needs to alternate hot water and cold water for cleaning during the cleaning process, and the deformation degree caused by cold water and hot water on the plastic tank body is different, and when hot water is used for cleaning, the hot steam rises to the upper part of the tank body 1, and when cold water is used for cleaning, the cold water is generally located at the bottom of the tank body 1. Therefore, the deformation of the cold shrinkage at the bottom of the tank body 1 is the largest. The third metal reinforcement 8 structure can support the lower part of the plastic tank body 1 to prevent the lower part of the tank body 1 from internal deformation due to cold shrinkage; second, an ultrasonic sounding device 4 is provided in the tank-type cleaning machine, and the third metal reinforcement 8 structure can resonate with the ultrasonic sounding device 4 to enhance the ultrasonic cleaning effect.

[0047] In this embodiment, the sink body 1 is made of plastic, which has strong plasticity and is convenient for deepening the depth of the sink body as needed, which improves the conditions for further developing new functions and structures of the sink type cleaning machine. Of course, the plastic sink body also greatly reduces the production cost compared with the stainless steel sink body; in this embodiment, the sink body 1 is installed on the cabinet countertop by using a metal assembly frame 2, which solves the problem of small bearing capacity of the shelf 12 of the plastic sink body 1 and improves the installation stability of the sink body 1; in addition, in this embodiment, a first metal reinforcement 3' is arranged on the inner wall surface of the upper part of the sink body 1. The first metal reinforcement 3' can prevent the sink body 1 from being deformed by heat on the one hand, and can also cooperate with the ultrasonic wave in the sink cleaning machine The sound-generating device 4 generates resonance to improve the ultrasonic cleaning effect; in this embodiment, a second metal reinforcement 3 is arranged on the outer periphery of the middle and lower part of the water tank body 1. On the one hand, the second metal reinforcement 3 can prevent the water tank body 1 from being deformed by heat or cold, and at the same time, it can also reduce the noise generated by the water flow hitting the inner wall of the water tank body 1, and accelerate the condensation speed of high-temperature steam, accelerate the drying speed in the washing chamber 10, and improve the cleaning effect; in this embodiment, a third metal reinforcement 8 is arranged on the inner wall surface of the lower part of the water tank body 1. On the one hand, the third metal reinforcement 8 can prevent the water tank body 1 from being deformed by heat or cold, and at the same time, it can resonate with the ultrasonic sound-generating device 4 at the bottom of the water tank cleaning machine to improve the ultrasonic cleaning effect.

[0048] Embodiment 2:

[0049] The difference between this embodiment and the first embodiment is that the structure of the third metal reinforcement 8 ′ is different.

[0050] like Figure 8 , 9As shown, the third metal reinforcement 8' of this embodiment is formed as an annular plate extending up and down in the second receiving groove 14, the upper edge of the annular plate contacts the upper edge of the second receiving groove 14, and the lower edge of the annular plate contacts the lower edge of the second receiving groove 14. The upper edge of the annular plate is bent into the second receiving groove 14 to form a fourth U-shaped structure 81' with an opening facing downward, the outer side of the fourth U-shaped structure 81' contacts the inner wall of the second receiving groove 14, the lower edge of the annular plate is bent into the second receiving groove 14 to form a fifth U-shaped structure 82' with an opening facing upward, the outer side of the fifth U-shaped structure 82' contacts the inner wall of the second receiving groove 14, and the annular plate and the fourth U-shaped structure 81' and the fifth U-shaped structure 82' on the annular plate together form a third cavity 80' with the inner wall of the second receiving groove 14.

[0051] The third metal reinforcement 8' in this embodiment has the following functions in addition to the functions of the third metal reinforcement 8 in Embodiment 1. Since the hot water will fall back to the lower part of the water tank body 1 after being sprayed out by the spray arm 5 and stay in the lower part of the water tank body 1 for a certain period of time, the third cavity 80' can improve the thermal insulation performance of the lower part of the water tank body 1 and save energy consumption, and can also achieve a certain degree of sound insulation effect.

[0052] The inner wall surface of the annular plate of this embodiment is provided with a plurality of protrusions 83' arranged at intervals, and the protrusions 83' are formed integrally with the annular plate, and the positions corresponding to the protrusions 83' on the outer wall surface of the annular plate are recessed toward the washing chamber 10. With the above structure, the protrusions 83' can further strengthen the strength of the lower part of the water tank body 1, and at the same time, the protrusions 83' of the inner convex and outer concave structure greatly enhance the elasticity of the annular plate and form a stronger resonance with the ultrasonic wave, further improving the cleaning effect.
