Description

Technical Field

[0001] The invention relates to a water tank and a cleaning machine. Background Art

[0002] At present, the sinks of sink-type cleaning machines on the market are generally made of stainless steel, and the processing methods are mainly welding and deep drawing.

[0003] 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. To achieve good sealing at the welding point will lead to low welding efficiency and high costs, and if the sealing effect at the welding point is poor, it cannot meet the requirements. For the deep drawing process, the sink drawn by the deep drawing process is generally less than the opening width of the sink, and it is difficult to increase the depth of the sink. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a water tank that allows internal and external liquid communication at a high water level to reduce welding process requirements and improve production efficiency in view of the current status of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned water tank in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a water tank, including a water tank bottom plate, a water tank side plate and a surrounding plate, the edge of the water tank bottom plate is formed with a first surrounding edge extending upward, the first surrounding edge is bent outward to form a support, the bottom of the water tank side plate is welded to the support and a weld is left between the support, the surrounding plate is sleeved on the outer periphery of the water tank side plate, the lower end of the surrounding plate abuts against the support and the support is sealed and connected, the inner surface of the surrounding plate and the upper surface of the support and the outer surface of the water tank side plate together enclose a cavity, and the cavity is connected to the inner cavity of the water tank through a weld.

[0007] Preferably, a partition extending toward the side plate of the water tank is provided on the inner surface of the enclosure to separate the cavity into an upper cavity and a lower cavity, and a filter hole is provided on the partition for fluid exchange between the upper cavity and the lower cavity. The above structure can prevent large particles on the partition from falling into the lower cavity, while allowing fluid communication between the upper cavity and the lower cavity. When the water level in the water tank is high during fruit and vegetable washing, it is convenient to maintain the balance of the internal and external water levels through fluid exchange.

[0008] Preferably, the upper cavity is filled with absorbent foam arranged near the partition, the upper edge of the absorbent foam is lower than the upper edge of the enclosure, and the space in the upper cavity and above the absorbent foam forms a storage area for storing salt. When washing fruits and vegetables, the water level is high, and there is fluid exchange between the cavity and the sink. By utilizing the fluid exchange, salt water is automatically added to the sink, which is beneficial to improving the washing effect of fruits and vegetables; while in the state of washing dishes, the water level is low, and there is no fluid exchange between the cavity and the sink, so salt can continue to be stored in the storage area and the absorbent foam.

[0009] In order to facilitate the introduction of salt, the upper edge of the enclosure is gradually inclined outward from bottom to top to form an introduction port for convenient salt introduction.

[0010] Preferably, a concentration sensor for detecting the concentration of salt water is arranged in the lower cavity, and the sensor is connected to an alarm outside the water tank. When the concentration sensor detects that the concentration of salt water is lower than a set value, the alarm will sound, prompting the user to add salt.

[0011] Preferably, the cavity forms a soundproof cavity arranged around the water tank. The cavity of the present invention also has the effect of a soundproof cavity, reducing the loud noise generated by the upward spray of the water jet when washing dishes.

[0012] In order to facilitate connection, the bottom edge of the sink side plate is provided with a connecting edge bent outward, and the connecting edge abuts against and is welded to the support platform.

[0013] Preferably, a first sealing ring is provided between the bottom edge of the enclosure and the support platform, and at least a part of the first sealing ring is embedded in the bottom edge of the enclosure. This structure can maintain the sealing of the cavity, and since the fluid flow and water pressure in the cavity are very small, a common sealing ring can be used to obtain a good seal.

[0014] In order to facilitate assembly and connection, a connecting arm with a mounting hole arranged close to the support is provided on the outer surface of the enclosure, and correspondingly, a stud for screws to pass through is provided on the support corresponding to the mounting hole.

[0015] Preferably, the water tank top plate is also included, and the water tank top plate is welded to the top of the water tank side plate. This structure is convenient for the production of the water tank top.

[0016] Preferably, the top edge of the sink side plate extends outward to form a mounting platform, and the horizontal portion of the sink top plate is supported and welded on the mounting platform. The outer periphery of the sink top plate has an upper portion extending upward and the inner side has a lower portion extending close to the inner side surface of the sink side plate.

[0017] Preferably, the top of the water tank side plate protrudes outward near the mounting platform to form a supporting edge on its inner surface, the lower part of the water tank top plate is arranged vertically and the lower edge is bent outward to abut against the supporting edge, and the lower part of the water tank top plate and the water tank side plate above the supporting edge jointly enclose a receiving cavity, and a second sealing ring is arranged in the receiving cavity. The above structure is conducive to improving the assembly sealing of the water tank top.

[0018] A cleaning machine comprises the above-mentioned water tank, wherein a part of the bottom plate of the water tank is concave to form a water return area.

[0019] In the tableware washing state, the water level in the sink is not higher than the upper edge of the first surrounding edge; in the fruit and vegetable washing state, the water level in the sink is higher than the upper edge of the first surrounding edge but lower than the upper edge of the enclosure.

[0020] Compared with the prior art, the advantages of the present invention are: the present invention welds the sink bottom plate and the sink side plate, but at the same time, reduces the welding process requirements and leaves a weld, that is, there is no requirement for sealing during welding or even a lower requirement, so as to reduce welding costs and improve welding efficiency. The present invention arranges a surrounding plate outside the sink, and a cavity is enclosed between the surrounding plate and the sink. The cavity is connected to the inner cavity of the sink through the weld, which can be connected with the fluid, thereby avoiding water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0025] like Figures 1 to 3 As shown, the sink of this embodiment includes a sink bottom plate 1, a sink side plate 2, a surrounding plate 3, and a sink top plate 4. The edge of the sink bottom plate 1 is formed with a first surrounding edge 11 extending upward, and the first surrounding edge 11 is bent outward to form a support 12. The bottom of the sink side plate 2 is welded to the support 12 and a weld is left between the support 12 (not shown in the figure). The surrounding plate 3 is sleeved on the outer periphery of the sink side plate 2, and the lower end of the surrounding plate 3 abuts against the support 12 and the support 12 is sealed. The inner surface of the surrounding plate 3 and the upper surface of the support 12 and the outer surface of the sink side plate 2 together enclose a cavity 10, and the cavity 10 is connected to the inner cavity of the sink through a weld.

[0026] The inner surface of the enclosure 3 is provided with a partition 31 extending toward the side plate 2 of the water tank so as to divide the cavity 10 into an upper cavity 101 and a lower cavity 102. The partition 31 is provided with a filter hole 311 for fluid exchange between the upper cavity 101 and the lower cavity 102. The above structure can prevent large particles on the partition 31 from falling into the lower cavity 102, and allow fluid communication between the upper cavity 101 and the lower cavity 102. When the water level in the water tank is high during fruit and vegetable washing, it is convenient to maintain the balance of the internal and external water levels through fluid exchange.

[0027] The upper cavity 101 is filled with water-absorbing foam 5 arranged near the partition 31, and the upper edge of the water-absorbing foam 5 is lower than the upper edge of the enclosure 3. The space in the upper cavity 101 and above the water-absorbing foam 5 forms a storage area for storing salt. When washing fruits and vegetables, the water level is high, and there is fluid exchange between the cavity 10 and the sink. By utilizing the fluid exchange, salt water is automatically added to the sink, which is beneficial to improving the washing effect of fruits and vegetables; while in the state of washing dishes, the water level is low, and there is no fluid exchange between the cavity 10 and the sink, so the salt can continue to be stored in the storage area and the water-absorbing foam 5.

[0028] In order to facilitate the introduction of salt, the upper edge of the enclosure 31 is gradually inclined outward from bottom to top to form an introduction port 32 for convenient introduction of salt.

[0029] A concentration sensor 6 for detecting the concentration of salt water is arranged in the lower cavity 102, and the sensor 6 is connected to the alarm outside the water tank. When the concentration sensor 6 detects that the concentration of salt water is lower than the set value, the alarm will sound, prompting the user to add salt.

[0030] The cavity 10 of this embodiment forms a soundproof cavity arranged around the sink. The cavity 10 of this embodiment also has the effect of a soundproof cavity, reducing the loud noise generated by the upward spray of the spraying water column when washing dishes.

[0031] In order to facilitate connection, the bottom edge of the sink side plate 2 is provided with a connecting edge 21 bent outward, and the connecting edge 21 abuts against and is welded to the support platform 12 .

[0032] A first sealing ring 100 is provided between the bottom edge of the enclosure 3 and the support platform 12, and at least a part of the first sealing ring 100 is embedded in the bottom edge of the enclosure 3. This structure can maintain the sealing of the cavity 10, and since the fluid flow and water pressure in the cavity 10 are very small, a common sealing ring can be used to obtain a good seal.

[0033] In order to facilitate assembly and connection, a connecting arm 33 with a mounting hole 331 is provided on the outer surface of the enclosure 3 and arranged close to the support platform 12. Correspondingly, a stud 121 for screws to pass through is provided on the support platform 12 and arranged corresponding to the mounting hole 331.

[0034] In this embodiment, the water tank top plate 4 is welded to the top of the water tank side plate 2. This structure facilitates the production of the water tank top. The top edge of the water tank side plate 2 extends outward to form a mounting platform 22, and the horizontal portion 41 of the water tank top plate 4 is supported and welded on the mounting platform 22. The outer periphery of the water tank top plate 4 has an upper portion 42 extending upward, and the inner side has a lower portion 43 extending close to the inner side of the water tank side plate 2.

[0035] The top of the water tank side plate 2 protrudes outward near the mounting platform 22 to form a supporting edge 23 on its inner surface. The lower portion 43 of the water tank top plate 4 is arranged vertically and the lower edge is bent outward to abut against the supporting edge 23. The lower portion 43 of the water tank top plate 4 and the water tank side plate 2 above the supporting edge 23 together enclose a receiving cavity 40, and a second sealing ring 200 is arranged in the receiving cavity 40. The above structure is conducive to improving the assembly sealing of the water tank top.

[0036] The cleaning machine of this embodiment includes the above-mentioned water tank, and a part of the bottom plate 1 of the water tank is concave to form a water return area 13.

[0037] When washing dishes, the water level in the sink is no higher than the upper edge of the first surrounding edge 11; when washing fruits and vegetables, the water level in the sink is higher than the upper edge of the first surrounding edge 11 and lower than the upper edge of the enclosure 3, and the specific water level is between the upper edge of the enclosure 3 and the upper edge of the absorbent foam 5.

[0038] In this embodiment, the sink bottom plate 1 and the sink side plate 2 are welded, but at the same time, the welding process requirements are reduced and welds are left, that is, there is no requirement for sealing during welding or even a lower requirement, so as to reduce welding costs and improve welding efficiency. In this embodiment, a surrounding plate 3 is arranged outside the sink, and a cavity 10 is enclosed between the surrounding plate 3 and the sink. The cavity 10 is connected to the inner cavity of the sink through the weld, which can provide fluid communication and avoid water leakage. The connection between the surrounding plate 3 and the sink bottom plate 1 is located outside the washing cavity, so there is no situation of being hit by a high-pressure water column. Therefore, the requirements for the sealing structure are low, which can reduce costs.
