Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to a cleaning machine. Background Technology

[0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt and grime and clean them. Dishes are placed in baskets inside the dishwasher cabinet. A typical dishwasher includes a pump and spray nozzles for spraying washing water, and a heater for generating hot water.

[0003] For example, the Chinese utility model patent disclosed in patent number CN201821312730.5 (publication number CN209236073U) entitled "A dishwasher spray arm water pipe assembly and its dish rack device" includes an upper spray arm water pipe and an upper spray arm, the spray arm water pipe and the upper spray arm are connected to each other, and both are installed at the bottom of the dish rack of the dishwasher.

[0004] From the appendix of this patent Figure 10 As you can see, the tableware in the dish basket is distributed in three areas, which are arranged sequentially along the length of the dish basket. That is, the three areas for placing tableware are arranged side by side. Currently, the areas for placing tableware in the dish basket are basically arranged in this way, which is a relatively simple arrangement. Furthermore, when placing tableware, users may place it from front to back or vice versa, which can easily lead to mistakes.

[0005] Furthermore, the irregular arrangement of the tableware area can easily lead to cleaning dead spots if the number of spray holes on the spray arm is small, resulting in some tableware not being rinsed or not being rinsed clean. On the other hand, if the number of spray holes is large, the arrangement of the spray holes will also be irregular, and too many spray holes may also cause the spray arm to vibrate when it is working. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a cleaning machine with a small number of spray holes in the spray arm, in view of the current state of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a washing machine that makes it easier for users to place tableware, in light of the current state of the prior art.

[0008] The technical solution adopted by the present invention to solve the first and second technical problems mentioned above is: a washing machine, including a tableware rack for placing tableware;

[0009] Spray arm, including

[0010] The main body is located below the cutlery rack. The main body has a flow channel extending along the length of the main body. The main body has a water inlet connected to the flow channel, and the top wall of the main body has multiple spray holes connected to the flow channel.

[0011] The cutlery rack is characterized by comprising:

[0012] The frame has an internal storage space and a plurality of first drainage holes connected to the storage space. The storage space of the frame includes at least two storage areas for placing tableware. With the central part of the storage space as the center, the at least two storage areas are arranged sequentially along the circumference of the central part of the storage space, and each storage area extends from the central part of the storage space toward the periphery of the storage space.

[0013] The body is strip-shaped, and the nozzles are arranged at intervals along the length of the body.

[0014] To ensure the nozzles are aimed at the tableware, at least two placement areas are symmetrically distributed on either side of the central portion of the receiving space. The central portion of the main body faces the central portion of the receiving space. Using the central portion of the main body as a boundary, the nozzle on one side of the central portion is designated as the first nozzle, and the nozzle on the other side is designated as the second nozzle. The first and second nozzles have opposite inclination directions. This arrangement of the first and second nozzles effectively creates a symmetrical arrangement, accommodating the two symmetrically positioned placement areas.

[0015] In order to ensure that the tableware can be placed in an orderly manner in the storage area, at least two sets of dividers are arranged in sequence along the direction away from the center of the storage space. The dividers divide the storage area into multiple storage areas for accommodating individual tableware, and the dividers allow the tableware in the corresponding storage area to be placed close together.

[0016] The spray nozzles located on the same side of the body's center gradually decrease in angle relative to the upper surface of the body as they move away from the center. The water jets from each nozzle are positioned between adjacent sets of separators. This allows the water jets to be directed towards the open end of the tableware for cleaning.

[0017] The divider can have various structural forms, such as a plate. In a simpler form, each set of dividers includes two circumferentially spaced columns arranged along the center of the receiving space, with each column extending vertically. The tableware is positioned by resting against the columns.

[0018] To facilitate the placement of the dividers within the frame, each of the storage areas is equipped with a base, and the base has a second drainage hole. The dividers in each storage area are placed on the base. This allows the dividers to be placed in the base first, and then the base can be placed in the receiving space of the frame.

[0019] To allow for the placement of tableware of different sizes in the storage area, at least two sets of dividers must have different distances between their pillars. This allows for the placement of larger tableware with wider distances between the pillars, and smaller tableware with narrower distances.

[0020] To facilitate cleaning and maintenance of the shelving unit (which consists of a base and dividers), the base is detachably mounted on the frame via connectors.

[0021] The base can have various structural forms. A simple base is an annular structure formed by a strip, with the inner area enclosed by the strip serving as the second drainage hole. The connector can also have various structural forms, such as straps. However, straps are cumbersome when connecting the base and frame. To facilitate easy assembly and disassembly of the base and frame, the connector includes a mounting base and a buckle on top of the mounting base. The frame is connected to the mounting base, and the buckle has a groove with an opening facing the base, allowing the base to pass through the groove. This structural form of the base is simple and easy to install on the buckle; furthermore, the base can be inserted into or removed from the buckle through the opening of the groove.

[0022] In order to prevent the base from coming out of the slot without external force, the slot opening is elastic. In its natural state, the diameter of the slot is greater than or equal to the outer diameter of the corresponding part of the base, but the size of the slot at the opening position is slightly smaller than the outer diameter of the corresponding part of the base.

[0023] Preferably, the frame is a perforated structure made of multiple frame strips, allowing water to drain out, thus providing a first drainage hole on the frame. The mounting base has mounting holes with openings facing the frame strips, and the frame strips are detachably inserted into the mounting holes. This allows the frame strips to be inserted into or removed from the mounting holes from their openings; furthermore, the connectors are detachably connected to the frame, allowing the base to be installed in different areas of the storage space as needed, i.e., the position of the storage area can be adjusted as required.

[0024] To prevent the frame strip from coming out of the mounting hole without external force, the mounting hole is provided with an elastic limiting part. When the frame strip is inserted into the mounting hole, the limiting part is located outside the frame strip and abuts against it; or the groove of the mounting hole is elastic. In its natural state, the diameter of the mounting hole is greater than or equal to the outer diameter of the corresponding part of the frame strip, but the size of the mounting hole at the opening position is slightly smaller than the outer diameter of the corresponding part of the frame strip.

[0025] To ensure that the base can be assembled onto the connectors even with certain manufacturing errors, each base has at least two connectors. At least one connector is designated as the first connector, and the others as the second connectors. The mounting base and buckle of the first connector are fixedly arranged relative to each other. The buckle of the second connector is rotatably connected to the mounting base via a vertically extending mounting shaft. The second connector offers greater flexibility; even with manufacturing errors, rotating the buckle of the second connector relative to the mounting base by a certain angle ensures the base can be installed.

[0026] The spray arm is typically located below the frame. To prevent the frame from obstructing water flow and affecting the cleaning of tableware, the frame is a perforated structure made of multiple frame strips that allow water to drain. The bottom frame strips are ring-shaped, with multiple ring-shaped strips arranged concentrically and radially spaced apart. The ring-shaped area enclosed by the innermost frame strips forms the central part of the water-receiving space. This structure of the frame results in a large number of perforated areas at the bottom, facilitating water flow without obstruction.

[0027] Compared with the prior art, the advantages of the present invention are as follows: 1. The tableware placement area of ​​the present invention is arranged sequentially along the circumference of the central part of the accommodating space. This arrangement is relatively novel and regular. When placing tableware, the user can simply place the tableware from the inside out (the inside refers to the part closer to the central part of the accommodating space, and the outside refers to the part farther from the central part of the accommodating space) in order, without making a mistake. 2. Because the placement area of ​​the present invention is arranged sequentially along the circumference and has a regular arrangement, the spray holes can be arranged along the length of the body, basically in a straight line. This allows for the design of fewer spray holes while ensuring that all tableware is rinsed. Furthermore, because the spray holes are arranged regularly in a straight line, the vibration of the spray arm during operation can be reduced. Attached Figure Description

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] like Figures 1-11 As shown, the washing machine of this preferred embodiment can be used to wash fruits and vegetables or tableware (such as bowls and plates). The washing machine includes a tableware rack and a spray arm 4. Of course, the washing machine also includes a water pump assembly, a housing, etc., which are conventional components and will not be described in detail here.

[0041] The cutlery rack includes a frame 1 and a shelf 2. The frame 1 has a storage space 11 inside. The frame 1 has a plurality of first drainage holes 12 connected to the storage space 11. In this embodiment, the frame 1 is cubic and is a hollow structure made of multiple frame strips 13 that allows water to drain out, thereby giving the frame 1 the first drainage holes 12.

[0042] like Figures 1-3 As shown, the accommodating space 11 of the frame 1 includes at least two storage areas for placing tableware. Centered on the central part of the accommodating space 11, at least two storage areas are arranged sequentially along the circumference of the central part of the accommodating space 11. Each storage area extends from the central part of the accommodating space 11 toward the periphery of the accommodating space 11. In the direction away from the central part of the accommodating space 11, at least two sets of partitions 22a are arranged sequentially at intervals in each storage area. The partitions 22a divide the storage area into multiple accommodating areas 221 for accommodating individual tableware. The partitions 22a allow tableware in the corresponding accommodating areas 221 to be placed close together.

[0043] In this embodiment, each storage area is provided with a base 21. The base 21 is an annular body formed by a strip-shaped member. The inner area enclosed by the strip-shaped member is the second drain hole 211. Each storage area is separated by a partition 22a on the base 21. Each partition 22a includes two columns 22 spaced circumferentially along the central part of the accommodating space 11, and each column 22 extends vertically. The tableware is positioned by resting against the columns 22. The structure formed by the base 21 and the columns 22 together is a shelf 2 for placing tableware.

[0044] In this embodiment, the base 21 and the column 22 can be designed as a single piece, or the column 22 can be welded to the base 21. In this way, during use, the shelf 2 can be placed entirely within the accommodating space 11 of the frame 1. Figure 3 As shown, the cutlery can rest against the column 22 between ab or between bc.

[0045] To allow for the placement of tableware of different sizes in the storage area, at least two sets of dividers 22a have different distances between their pillars 22. Thus, the larger distance between the pillars 22 of the dividers 22a allows for the placement of larger tableware; the smaller distance allows for the placement of smaller tableware. Figure 3 As can be seen, the base 21 is small at both ends and large in the middle, with small tableware placed at both ends and large tableware placed in the middle.

[0046] like Figure 2 , 3 As shown, the base 21 is detachably mounted on the frame 1 via a connector.

[0047] like Figures 4-8 As shown, the connector includes a mounting base 31 and a fastener 32 disposed on the top of the mounting base 31. The frame 1 is connected to the mounting base 31. The fastener 32 has a fastening groove 321 with an opening facing the base 21, and the base 21 can be inserted into the fastening groove 321. This structure of the base 21 is simple and easy to install on the fastener 32; and the base 21 can be inserted into or removed from the fastening groove 321 from the opening of the fastening groove 321. In order to prevent the base 21 from falling out of the fastening groove 321 without external force, the opening of the fastening groove 321 is elastic. In its natural state, the diameter of the fastening groove 321 is greater than or equal to the outer diameter of the corresponding part of the base 21, but the size of the fastening groove 321 at the opening position is slightly smaller than the outer diameter of the corresponding part of the base 21.

[0048] The mounting base 31 has a mounting hole 311 with an opening facing the frame strip 13, and the frame strip 13 can be inserted into the mounting hole 311. In this way, the frame strip 13 can be inserted into the mounting hole 311 or removed from the mounting hole 311 through the opening.

[0049] Each base 21 has at least two connectors, at least one of which is designated as the first connector 3a, and the remaining connectors are designated as the second connectors 3b. In this embodiment, each base 21 has one first connector 3a and two second connectors 3b.

[0050] like Figure 4 , 5 As shown, the mounting base 31 and the buckle 32 of the first connector 3a are fixedly arranged relative to each other.

[0051] like Figure 6 , 7 As shown in Figure 8, the buckle body 32 of the second connector 3b is rotatably connected to the mounting base 31 via the mounting shaft 33, which extends vertically. The connection method of the second connector 3b is more flexible. Even if the base 21 has certain manufacturing errors, rotating the buckle body 32 of the second connector 3b relative to the mounting base 31 by a certain angle can ensure that the base 21 can be installed.

[0052] To prevent the frame strip 13 from coming out of the mounting hole 311 without external force, in this embodiment, as follows: Figure 4 , 5 As shown, the groove of the mounting hole 311 of the first connector 3a is elastic. In its natural state, the diameter of the mounting hole 311 is greater than or equal to the outer diameter of the corresponding part of the frame strip 13, but the size of the mounting hole 311 at the opening position is slightly smaller than the outer diameter of the corresponding part of the frame strip 13.

[0053] like Figures 6-8 As shown, the second connector 3b has a flexible limiting part 312 in the mounting hole 311. When the frame strip 13 passes through the mounting hole 311, the limiting part 312 is located outside the frame strip 13 and abuts against the frame strip 13.

[0054] like Figure 2 As shown, in this embodiment, the position of the central part of the adjacent accommodating space 11 of the base 21 is connected to the frame strip 13 through the second connector 3b, and the position of the base 21 near the periphery of the frame 1 is connected to the frame strip 13 through the first connector 3a.

[0055] The advantages of the connector in this embodiment are: 1. The base 21 can be detachably installed on the connector, so that the shelf 2 can be detached from the frame 1, which is convenient for cleaning, replacement, maintenance and other work; 2. The connector can be detached from the frame 1, so that the base 21 can be installed in different positions in the frame 1 as needed, so that the position of the storage area can be adjusted as needed.

[0056] The spray arm 4 is generally located below the frame 1. To prevent the frame 1 from obstructing the water flow and affecting the cleaning of tableware, the frame 1 is a hollow structure made of multiple frame strips 13 that allow water to drain. The frame strips 13 at the bottom of the frame 1 are ring-shaped, and multiple ring-shaped frame strips 13 are arranged concentrically and radially at intervals. The ring-shaped area a enclosed by the innermost frame strip 13 is the central part of the receiving space 11. This structure of the frame 1 results in a large number of hollow areas at the bottom of the frame 1, which facilitates the flow of water and does not obstruct the water flow.

[0057] The spray arm 4 includes a body 41 located below the cutlery rack. The body 41 is strip-shaped and has a flow channel (not shown in the figure) extending along the length of the body 41. The bottom of the body 41 is provided with a water inlet (not shown in the figure) connected to the flow channel, and the top wall of the body 41 is provided with multiple spray holes connected to the flow channel. The spray holes are arranged at intervals along the length of the body 41.

[0058] At least two storage areas are symmetrically distributed on both sides of the central part of the accommodating space 11, such as... Figure 2 As shown, there are four storage areas, arranged symmetrically in pairs; Figure 10 As shown, there are three storage areas, two of which are arranged symmetrically.

[0059] The middle portion of the main body 41 faces the central part of the receiving space 11. Using the middle portion of the main body 41 as a boundary, a nozzle located on one side of the middle portion of the main body 41 is designated as the first nozzle 411, and a nozzle located on the other side of the middle portion of the main body 41 is designated as the second nozzle 412. The first nozzle 411 and the second nozzle 412 have opposite inclination directions. Thus, the first nozzle 411 and the second nozzle 412 are symmetrically arranged, adaptable to two symmetrically arranged storage areas. For the nozzles located on the same side of the middle portion of the main body 41, the inclination angle of the nozzles relative to the upper surface of the main body 41 gradually decreases along the direction away from the middle portion of the main body 41. The water jets 413 ejected from each nozzle are located between two adjacent partitions 22a, thereby causing the water jets 413 to clean the open end of the tableware. Preferably, the extension direction of the water jets 413 is perpendicular to the tangent direction of the curved surface of the tableware.

[0060] In the specification and claims of this invention, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of the invention. However, these terms are used herein only for the purpose of convenience of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Therefore, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations.

[0061] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts, collectively referred to as the first part and the second part, meaning that a fluid, gas, liquid, or a mixture of both can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber that allows fluid to flow through, or a combination of the above.
