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 which can prevent the deformation of the plastic tank body and has heat preservation and noise reduction effects 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, the top of the sink body has an opening connected to the washing chamber, characterized in that: the open part of the sink body is made of metal at least in the position in contact with the installation plane, and the sink body part below it is made of plastic material, and the outer peripheral wall of the sink body is provided with spaced reinforcing ribs, and the outer wall of the sink body is also provided with a metal plate on the periphery of the reinforcing ribs, and the metal plate and the reinforcing ribs together enclose a cavity.

[0008] In the above scheme, the middle part of the water tank body has at least two first reinforcing ribs arranged in an upper and lower interval, and the outer wall surface of the water tank body is provided with a second reinforcing rib arranged to cross the first reinforcing rib, and the second reinforcing rib and the first reinforcing rib enclose at least one groove with an external port, and the metal plate is placed on the external port to form the cavity. A metal plate can cover one groove or multiple grooves, and one or more cavities are formed accordingly. During the cleaning process of the cleaning machine, most of the water sprayed by the spray arm is sprayed to the middle part of the inner wall of the water tank body, and the above cavity is formed in the middle part of the water tank body, which can keep the hot water in the washing chamber warm and reduce energy consumption; at the same time, the plastic water tank is easy to generate louder noise when hit by water, so the above structure can play a good sound insulation role and reduce noise.

[0009] 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.

[0010] Preferably, the metal assembly frame includes an annular plate formed into an annular shape and arranged vertically, the upper end of the annular plate extends outward to form a support plate that can be supported on the cabinet countertop, the annular plate is inserted into the water tank body from the open opening of the water tank body and is closely connected to the inner wall of the water tank body, the open edge extends outward to form a shelf that can be placed on the installation plane, and the shelf is arranged closely to the lower wall of the support plate. The above-mentioned metal assembly frame and the water tank body are bonded to each other or fixedly connected by screws.

[0011] Preferably, the water tank body portion corresponding to the annular plate is formed into a grid-like reinforcing rib structure, and the reinforcing rib structure has a plurality of openings arranged at intervals for the annular plate to be exposed. The washing machine generally uses hot water and cold water alternately for washing. After the hot water washing is completed, a large amount of steam will be retained in the washing chamber. The metal annular plate is conducive to condensing the steam, and the opening on the upper part of the water tank body for the annular plate to be exposed makes the annular plate and the outside world have a better heat exchange effect, which is conducive to accelerating the condensation of steam and allowing the dishes to be quickly dried after washing.

[0012] In order to facilitate assembly and connection, a support platform arranged along the circumferential direction is formed on the inner wall of the water tank body, the annular plate is arranged above the support platform, and the lower edge of the annular plate is bent inward to form a folding plate that can be pressed against the support platform.

[0013] Preferably, the support platform is provided with a circumferentially arranged card slot, in which a sealing ring is embedded to abut against the lower wall of the folding plate. There is inevitably a gap between the plastic water tank body and the metal assembly frame, and the provision of the sealing ring can solve the sealing problem between the plastic water tank body and the metal assembly frame, thereby preventing water from overflowing during use of the cleaning machine.

[0014] Preferably, a transversely arranged water guide strip is convexly disposed on the inner wall surface of the upper portion of the annular plate, which can not only prevent water from surging upwards, thus reducing the sealing requirements between the door body and the tank body, but also can guide the water flow to the dishes, thus improving the washing effect.

[0015] In order to improve the effect of the water guide bar in directing water flow to the dishes, the upper wall surface of the water guide bar gradually tilts toward the inside of the sink body from top to bottom and forms an angle a with the inner wall of the annular plate above it, and the lower wall surface of the water guide bar gradually tilts toward the outside of the sink body from top to bottom and forms an angle a with the inner wall of the annular plate below it, 95°≤a≤160°.

[0016] Preferably, the outer peripheral wall of the lower part of the water tank body has a plurality of third reinforcing ribs arranged at intervals in a vertical direction. During the washing process of the washing machine, hot water and cold water are often required for washing alternately, and the deformation degree caused by cold water and hot water to the plastic tank body is different. When washing with hot water, the hot steam rises to the upper part of the water tank body, while when washing with cold water, the cold water is generally located at the bottom of the water tank body. Therefore, the upper part of the plastic water tank body is easily deformed by high-temperature steam, and the lower part of the water tank body is easily deformed by cold shrinkage, and the cold shrinkage deformation of the lower part of the water tank body is greater than the thermal deformation of the upper part of the water tank body. The above structure can support the water tank body and prevent the water tank body from being deformed due to cold or heat. When an ultrasonic sounding device is provided at the bottom of the water tank body, since the ultrasonic wave needs to be transmitted through water as a medium, the reinforcing ribs at the bottom of the water tank body are conducive to the transmission of the ultrasonic wave, thereby improving the cleaning effect.

[0017] As an improvement, an ultrasonic generator is provided at the bottom of the water tank body, a metal strip is embedded in the third reinforcing rib, and the metal strip is exposed on the inner wall surface of the water tank body. Since the cold shrinkage deformation of the lower part of the water tank body has a greater impact on the water tank than the thermal deformation of the upper part of the water tank body, the above structure is adopted to embed a metal strip in the reinforcing rib at the lower part of the water tank body, which can improve the support force of the lower part of the water tank body and prevent the lower part of the water tank body from internal deformation due to cold shrinkage; at the same time, the above metal strip can resonate with the ultrasonic sound generator to further enhance the ultrasonic cleaning effect.

[0018] Compared with the prior art, the advantages of the present invention are: the present invention uses plastic to make the sink body, which has strong plasticity and is convenient for deepening the sink body as needed, while also greatly reducing the production cost; the open part of the sink body of the present invention is made of metal at least in the position in contact with the installation plane, which solves the problem of low bearing capacity of the plastic sink body and improves the stability of the installation of the sink body; at the same time, the cavity enclosed by the reinforcing ribs and the metal plate on the side wall of the present invention can not only keep the high-temperature water in the sink body warm, but also play a sound insulation role, reducing the noise generated by the water flow rushing towards the inner wall of the sink body; in addition, the provision of the reinforcing ribs can effectively prevent the sink body from being deformed due to cold and heat, thereby improving the strength of the sink body.

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 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 for use, and the cabinet countertop is provided with an installation opening 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, and the edge of the opening 11 extends outward to form a shelf 12 that can be placed on the cabinet countertop.

[0026] The bottom of the water tank body 1 of this embodiment is provided with a water pump which can lift water from the bottom of the water tank body 1 and spray it upward through the spray arm. The bottom of the water tank body 1 is provided with an ultrasonic generator 4, which can effectively improve the cleaning effect.

[0027] The sink body 1 of this embodiment is a plastic sink body 1. Considering that the shelf 12 of the plastic sink body 1 has a low load-bearing capacity, the sink body 1 of this embodiment is installed on the cabinet countertop through a metal assembly frame 2. The metal assembly frame 2 is made of stainless steel. After installation, the outer edge of the metal assembly frame 2 is placed on the cabinet countertop. The metal assembly frame 2 includes an annular plate 21 formed into a ring shape and arranged vertically. The upper end of the annular plate 21 extends outward to form a support plate 22 that can be supported on the cabinet countertop. The annular plate 21 is inserted into the sink body 1 from the open opening 11 of the sink body 1 and is connected to the inner wall of the sink body 1. The shelf 12 is arranged close to the lower wall of the support plate 22. The metal assembly frame 3 and the sink body 2 are bonded to each other or fixedly connected by screws.

[0028] In this embodiment, the outer peripheral wall of the water tank body 1 is provided with spaced reinforcing ribs 3 to improve the strength of the water tank body 1. The middle part of the water tank body 1 has two first reinforcing ribs 31 arranged around the water tank body 1 and spaced up and down. The outer wall surface of the water tank body 1 is provided with a plurality of second reinforcing ribs 32 intersecting with the first reinforcing ribs 31 and extending vertically. The second reinforcing ribs 32 and the first reinforcing ribs 31 are enclosed to form a plurality of grooves 33 with external ports. The outer ports of the grooves 33 are covered with metal plates 7. The metal plates 7 and the corresponding first reinforcing ribs 31, the second reinforcing ribs 32 and the outer wall of the water tank body 1 are jointly enclosed to form cavities 70. A metal plate 7 can cover one groove 33 or multiple grooves 33, and one or more cavities 70 are formed accordingly. The metal plate 7 can be bonded to the reinforcing ribs 3 or fixed to the reinforcing ribs 3 by screws. During the cleaning process of the cleaning machine, most of the water sprayed by the spray arm is sprayed to the middle of the inner wall of the sink body 1, forming the above-mentioned cavity 70 in the middle of the sink body 1, which can keep the hot water in the washing chamber 10 warm and reduce energy consumption; at the same time, the plastic sink is prone to generate louder noise when hit by water, so the above-mentioned structure can play a good sound insulation role and reduce noise.

[0029] In this embodiment, the portion of the water tank body 1 corresponding to the annular plate 21 is formed into a grid-like reinforcing rib structure 13, and the reinforcing rib structure 13 has a plurality of openings 131 arranged at intervals for exposing the annular plate 21. The washing machine generally uses hot water and cold water alternately for washing. After the hot water washing is completed, a large amount of steam will be retained in the washing chamber 10. The metal annular plate 21 is conducive to condensing the steam, and the opening 131 on the upper part of the water tank body 1 for exposing the annular plate 21 makes the annular plate 21 and the outside world have a better heat exchange effect, which is conducive to accelerating the condensation of steam and allowing the dishes to be quickly dried after washing.

[0030] In order to facilitate assembly and connection, a support platform 14 arranged along the circumferential direction is formed on the inner wall of the water tank body 1, and an annular plate 21 is arranged above the support platform 14, and the lower edge of the annular plate 21 is bent inward to form a folding plate 211 that can be pressed against the support platform 14. A card slot 141 arranged along the circumferential direction is opened on the support platform 14, and a sealing ring 8 that can abut against the lower wall surface of the folding plate 211 is embedded in the card slot 141. There is inevitably a gap between the plastic water tank body 1 and the metal assembly frame 2. The provision of the above-mentioned sealing ring 8 can solve the problem of sealing between the plastic water tank body 1 and the metal assembly frame 2, and prevent water overflow during the use of the cleaning machine. A water guide strip 23 arranged horizontally is convexly provided on the inner wall surface of the upper part of the annular plate 21. The water guide strip 23 can not only prevent water from surging up, reduce the sealing requirements between the door body and the tank body, but also guide the water flow to the dishes to improve the cleaning effect.

[0031] In order to improve the effect of the water guide bar 23 in directing water flow to the dishes, the upper wall surface of the water guide bar 23 gradually tilts toward the inside of the sink body 1 from top to bottom and forms an angle a with the inner wall of the annular plate 21 above it, and the lower wall surface of the water guide bar 23 gradually tilts toward the outside of the sink body 1 from top to bottom and forms an angle a with the inner wall of the annular plate 21 below it, 95°≤a≤160°.

[0032] The outer peripheral wall at the bottom of the water tank body 1 is provided with a plurality of third reinforcing ribs 15 arranged at intervals in a vertical direction. During the washing process of the washing machine, hot water and cold water are often required for washing alternately, and the deformation degree caused by cold water and hot water to the plastic tank body 1 is different. When washing with hot water, the hot steam rises to the upper part of the water tank body 1, while when washing with cold water, the cold water is generally located at the bottom of the water tank body 1. Therefore, the upper part of the plastic water tank body 1 is easily deformed by high-temperature steam, and the lower part of the water tank body 1 is easily deformed by cold shrinkage, and the cold shrinkage deformation of the lower part of the water tank body 1 is greater than the thermal deformation of the upper part of the water tank body. The above structure can support the water tank body 1 and prevent the water tank body 1 from being deformed due to cold or heat. When an ultrasonic sounding device 4 is provided at the bottom of the water tank body 1, since the ultrasonic wave needs to be transmitted through water as a medium, the third reinforcing ribs 15 at the bottom of the water tank body 1 are conducive to the transmission of the ultrasonic wave, thereby improving the cleaning effect. A metal strip 151 is embedded in the third reinforcing rib 15, and the metal strip 151 is exposed on the inner wall surface of the water tank body 1. Since the cold shrinkage deformation of the lower part of the water tank body 1 has a greater impact on the water tank than the thermal deformation of the upper part of the water tank body 1, the above structure is adopted to embed the metal strip 151 in the reinforcing rib at the lower part of the water tank body 1, which can improve the support force of the lower part of the water tank body 1 and prevent the lower part of the water tank body 1 from internal deformation due to cold shrinkage; at the same time, the above metal strip 151 can resonate with the ultrasonic sounding device 4 to further enhance the ultrasonic cleaning effect.

[0033] The third reinforcing rib 15 , the first reinforcing rib 31 , the second reinforcing rib 32 , and the reinforcing rib structure 13 in this embodiment are all integrally formed by injection molding with the sink body 1 . The third reinforcing rib 15 may be formed by extending the second reinforcing rib 32 downward.

[0034] 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, thereby improving 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 the small bearing capacity of the shelf 12 of the plastic sink body 1 and improves the stability of the installation of the sink body 1. In addition, the cavity 70 formed by the reinforcing ribs 3 and the metal plate 7 on the side wall of this embodiment can not only keep the high-temperature water in the sink body 1 warm, but also play a sound insulation role, thereby reducing the noise generated by the water flow rushing towards the inner wall of the sink body 1. In addition, the provision of the reinforcing ribs 3 can effectively prevent the sink body 1 from being deformed due to cold or heat, thereby improving the strength of the sink body 1.
