[0041] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0042] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meanings of the above within the context of this invention as appropriate.

[0045] In some embodiments of the present invention, the device includes a body 1, a door panel 1, and a door lock device 3. The door panel 1 is rotatably connected to the body 1. The door lock device 3 includes a limiting elastic element 31 and a rotating arm 32. The limiting elastic element 31 is fixed on the body 1, and the rotating arm 32 is fixed at the lower end of the side of the door panel 1. The door panel 1 rotates to drive the rotating arm 32 to rotate between a first position 4 and a second position 5. The door panel 1 includes at least an open state and a closed state. When the door panel 1 is in the open state, the rotating arm 32 is located in the first position 4. When the door panel 1 is in the closed state, the rotating arm 32 is located in the second position 5, and the limiting elastic element 31 is locked.

[0046] Specifically, the limiting elastic element 31 is an elastic element, part of the door lock device 3, fixed to the side wall of the machine body 1, and provides a stable locking force in the appropriate position. The rotating arm 32 is an element fixed to the lower side of the door panel 1, also part of the door lock device 3. The rotating arm 32 rotates together with the door panel 1 and can switch between a first position 4 and a second position 5. The position of the rotating arm 32 determines the state of the door panel 1, i.e., the open or closed state. When the door panel 1 is in the open state, the rotating arm 32 is in the first position 4. At this time, the interior of the dishwasher is easily accessible, and the user can place or remove tableware and utensils. When the user closes the door panel 1, the door panel 1 begins to rotate, and the rotating arm 32 follows its movement. The rotation of the door panel 1 causes the rotating arm 32 to move from the first position 4 to the second position 5. When the door panel 1 is in the closed state and the rotating arm 32 is in the second position 5, the limiting elastic element 31 acts as a lock, providing sufficient elastic force to keep the door panel 1 tightly closed and preventing the door panel 1 from being accidentally opened during the washing process.

[0047] In commercial kitchens, dishwashers handle a large volume of tableware and utensils. Their structure and operating principle make them suitable for the high-intensity use of commercial kitchens. When using the dishwasher, the user arranges the tableware and utensils to be washed for quick placement into the machine body 1. The door panel 1 is opened, with the rotating arm 32 in the first position 4. The tableware and utensils are then placed inside the machine body 1. The door panel 1 is closed, ensuring it is in the closed position, with the rotating arm 32 in the second position 5. The dishwasher is then started, allowing it to automatically complete the washing cycle. After washing, the door panel 1 is unlocked, allowing the user to open it and remove the washed tableware and utensils for further processing and use.

[0048] Furthermore, when the dishwasher door panel 1 is closed, the rotating arm 32 is in the second position 5, and the limiting elastic element 31 is locked. This locking mechanism ensures that the door panel 1 is securely locked in the closed state, while allowing for easy unlocking when needed. The limiting elastic element 31 may be an elastic component, such as a spring or other material that provides a certain elastic force. When the door panel 1 is closed, the limiting elastic element 31 is compressed or deformed, and its elastic force locks the door panel 1 in the closed position. When opening the door panel 1, the user only needs to gently push the door panel 1, and the elastic force of the limiting elastic element 31 will release the lock, allowing the door panel 1 to move from the closed state to the open state. This design reduces the force required for the user to open the door panel 1, providing a more relaxed and convenient user experience. The cooperation between the limiting elastic element 31 and the rotating arm 32 ensures better tightness when the door panel 1 is closed, keeping it securely locked in the closed state, thereby preventing accidental opening and improving the safety of the dishwasher. With the coordinated action of the rotating arm 32 and the limiting elastic element 31, the user can open the door panel 1 with just a gentle push. This design reduces the force required for the user to open the door panel 1, providing a more relaxed and convenient user experience.

[0049] In the design of this dishwasher, when the door panel 1 is in the open state, the rotating arm 32 is located on the side plane of the side wall of the body 1, i.e., the first position 4. When the door panel 1 is closed, the rotating arm 32 will rotate to the bottom plane of the side wall of the body 1, i.e., the second position 5. At this time, the locking state of the rotating arm 32 and the limiting elastic member 31 can ensure that the door panel 1 is tightly closed and provide good sealing performance. The plane of the first position 4 and the plane of the second position 5 are perpendicular to each other.

[0050] In some embodiments of the present invention, the limiting elastic element 31 includes a spring sheet 311, which generates a deformation stroke through a fulcrum 312.

[0051] Specifically, the spring 311 has certain elastic properties. The spring 311 can be a thin sheet component made of elastic material, such as spring steel or other materials with elastic restoring force. The fulcrum 312 is the fixing point or rotation center of the spring 311, allowing the spring 311 to deform around the fulcrum 312. The fulcrum 312 is a structure fixed to the side wall of the dishwasher body 1. The spring 311 is fixed to the side wall of the dishwasher body 1 through the fulcrum 312. One end of the spring 311 is connected or fixed to the fulcrum 312, and the other end is locked to the rotating arm 32. When the door panel 1 is in the closed state, the spring 311 in the limiting elastic member 31 is subjected to the external force of the rotating arm 32 and undergoes a certain deformation, which helps to limit the movement of the door panel 1 and provide additional locking force. When the user needs to open the door panel 1, applying appropriate force causes the spring 311 to deform around the fulcrum 312, releasing the locked state of the rotating arm 32. This allows the door panel 1 to move from the closed state to the open state under the action of the rotating arm 32. The deformation stroke of the spring 311 provides easy opening and reliable locking of the door panel 1, ensuring a tight seal when closed and easy opening with a gentle push. The deformation stroke of the spring 311 can be adjusted as needed to provide appropriate locking force and convenient opening operation for the door panel 1.

[0052] In some embodiments of the present invention, the surface of the spring piece 311 is provided with an arc or an inclination; or the surface of the spring piece 311 is provided with a groove; or the surface of the spring piece 311 is provided with a plurality of striped limiting protrusions, the limiting protrusions being spaced apart.

[0053] Specifically, the dishwasher's spring plate 311 has a certain curved shape, which can be arc or slope. This design allows the spring plate 311 to limit the displacement of the rotating arm 32 during movement. The arc or slope of the spring plate 311 can be designed and adjusted according to specific needs. A groove can be provided on the surface of the spring plate 311, and the rotating arm 32 engages in the groove, thus providing a better limiting effect. The surface of the spring plate 311 can be provided with several striped limiting protrusions. These striped limiting protrusions can be arranged at equal intervals to increase friction and provide a more precise position limiting function. When the dishwasher door panel 1 is closed, these striped limiting protrusions interact with the rotating arm 32 to ensure the locking and stability of the door panel 1. When the door panel 1 is in the open state, the rotating arm 32 is in the first position 4. The curved shape, groove or striped limiting protrusion of the spring piece 311 has no limiting effect on the rotating arm 32. However, when the door panel 1 is in the closed state, the rotating arm 32 will move from the first position 4 to the second position 5 as the door panel 1 rotates. At the same time, the surface features of the spring piece 311 (arc, slope, groove or striped limiting protrusion) interact with the rotating arm 32 to provide a limiting effect and ensure the locking of the door panel 1, avoiding misoperation or accidental opening and improving the safety of the dishwasher.

[0054] In some embodiments of the present invention, the limiting elastic member 31 further includes a fixed connecting post 313 for fixing the limiting elastic member 31 to the body 1.

[0055] Specifically, the fixed connecting post 313 is typically a rigid rod-shaped element, with one end connected to the limiting elastic member 31 and the other end fixed to the side wall of the machine body 1 by appropriate fixing means (such as bolts, nuts, etc.). Through the fixed connection of the fixed connecting post 313, a stable connection relationship is established between the limiting elastic member 31 and the machine body 1 of the dishwasher. The fixed connecting post 313 of the limiting elastic member 31 plays a fixing role, ensuring a firm connection between the limiting elastic member 31 and the machine body 1. Thus, when the dishwasher door panel 1 is closed, through the elastic characteristics of the limiting elastic member 31 and the interaction of the rotating arm 32, the door panel 1 can be correctly locked in the closed position. The presence of the fixed connecting post 313 enables the limiting elastic member 31 to withstand the force and movement of the door panel 1 and maintain an appropriate position and angle.

[0056] In some embodiments of the present invention, the limiting elastic element 31 includes a spring and a limiting block 9 disposed at the front end of the spring. The surface of the limiting block 9 is provided with an arc or an inclination, and the rear end of the spring is fixed to the body 1.

[0057] Specifically, the limiting elastic element 31 includes a spring, which is a linear elastic element with elastic properties. The rear end of the spring is fixedly connected to the body 1 of the dishwasher by appropriate fixing means (such as bolts, nuts, etc.).

[0058] The limiting block 9 is located at the front end of the spring and is used to limit the travel of the door panel 1. The surface of the limiting block 9 has a curvature or slope, so that when the door panel 1 is closed, the limiting block 9 can generate appropriate contact and friction with the swing arm 32. Through the assembly of the spring and the limiting block 9, the limiting elastic element 31 can provide appropriate elastic support and limiting function. When the door panel 1 is closed, the spring of the limiting elastic element 31 is compressed, and at the same time, the contact between the limiting block 9 and other components generates an appropriate limiting force, locking the door panel 1 in the closed position. The spring of the limiting elastic element 31 and the limiting block 9 work together to provide appropriate elastic support and limiting function. When the door panel 1 reaches the designated position during the closing process, the contact and friction between the limiting block 9 and the swing arm lock the door panel 1 in the closed position. The presence of the spring provides appropriate elastic characteristics, allowing the limiting elastic element 31 to generate an appropriate reaction force when the door panel 1 is closed. The surface shape (curvature or slope) of the limiting block 9 provides a better limiting effect, ensuring that the door panel 1 is locked in the correct position.

[0059] In some embodiments of the present invention, a buffer elastic element 33 is provided on the rotating arm 32. One end of the buffer elastic element 33 is connected to the rotating arm 32, and the other end is connected to the body 1. When the door panel 1 is in the open state, the buffer elastic element 33 is in the energy storage state, and when the door panel 1 is in the closed state, the buffer elastic element 33 is in the energy release state.

[0060] Specifically, the buffer elastic element 33 is an elastic component located on the rotating arm 32. One end of it is connected to the rotating arm 32, and the other end is connected to the body 1. The buffer elastic element 33 can be a spring or other elastic material. Through the assembly method of the buffer elastic element 33, a connection is formed between it, the rotating arm 32, and the body 1. When the door panel 1 is in the open state, the buffer elastic element 33 is in an energy-storing state, i.e., compressed or stretched; when the door panel 1 is in the closed state, the buffer elastic element 33 is in an energy-releasing state, i.e., returns to its original shape. The presence of the buffer elastic element 33 provides a buffering and shock-absorbing effect when the door panel 1 is closed. When the door panel 1 is closed, the buffer elastic element 33 absorbs part of the impact force and transfers it to the elastic element to reduce the impact and noise when the door panel 1 is closed. The presence of the buffer elastic element 33 provides a buffering and shock-absorbing effect when the door panel 1 is closed, reducing the impact and noise generated by the closing of the door panel 1. The buffer elastic element 33 can store energy when the door panel 1 is open and release energy when the door panel 1 is closed, ensuring the realization of the buffering effect.

[0061] In some embodiments of the present invention, a connecting frame 6 for connecting the body 1 and the rotating arm 32 is also included. The connecting frame 6 includes a first connecting plate 61 and a second connecting plate 62. The second connecting plate 62 is connected to the first connecting plate 61, and the plane of the second connecting plate 62 is perpendicular to the plane of the first connecting plate 61.

[0062] Specifically, the connecting frame 6 is used to connect the rotating arm 32 and the body 1, and to connect other components. The connecting frame 6 includes a first connecting plate 61 and a second connecting plate 62. The connecting frame 6 is assembled by fixing the second connecting plate 62 onto the first connecting plate 61, so that the first connecting plate 61 and the second connecting plate 62 are perpendicular to each other. The limiting elastic element 31 is fixed onto the first connecting plate 61, which has a stable connection effect. The existence of the connecting frame 6 provides the connection between the rotating arm 32 and other components. It ensures the perpendicular relationship between the first connecting plate 61 and the second connecting plate 62, thereby achieving a stable connection. The second connecting plate 62 is located on the side of the side wall of the body 1, that is, the first position 4. When the rotating arm 32 is in the first position 4, the rotating arm 32 abuts against the second connecting plate 62, preventing the rotating arm 32 from shifting in the second position 5, thus having a limiting effect. The vertical arrangement of the first connecting plate 61 and the second connecting plate 62 allows the connecting frame 6 to adapt to forces and torques in different directions, increasing the stability and reliability of the system.

[0063] In some embodiments of the present invention, a mounting frame 7 is provided between the body 1 and the connecting frame 6. The mounting frame 7 includes a first mounting plate 71, a second mounting plate 72 and a third mounting plate 73. The first mounting plate 71 is fixedly connected to the side wall of the body 1, and the third mounting plate 73 is fixedly connected to the door frame of the body 1. The first mounting plate 71 and the third mounting plate 73 are connected through the second mounting plate 72.

[0064] Specifically, the mounting bracket 7 is located between the side wall of the machine body 1 and the connecting bracket 6, and is used to support and fix the connecting bracket 6. The mounting bracket 7 consists of a first mounting plate 71, a second mounting plate 72, and a third mounting plate 73. The first mounting plate 71 is fixedly connected to the side wall of the machine body 1, providing a support point for the connecting bracket 6. The second mounting plate 72 connects the first mounting plate 71 and the third mounting plate 73, serving as a connector. The third mounting plate 73 is fixedly connected to the door frame of the machine body 1, forming a stable connection between the mounting bracket 7 and the door frame of the machine body 1. Since the height of the door frame of the machine body 1 is greater than the height of the side wall of the machine body 1, there is a height difference between them. Therefore, there is also a height difference between the third mounting plate 73 connected to the door frame of the machine body 1 and the first mounting plate 71 connected to the side wall of the machine body 1. The third mounting plate 73 is bent towards the cleaning chamber to form the second mounting plate 72. The second mounting plate 72 can absorb this height difference and ensure the stability of the connection of the mounting bracket 7. The combination of the first mounting plate 71, the second mounting plate 72 and the third mounting plate 73 makes the connection between the connecting frame 6 and the side wall and door frame of the body 1 more secure.

[0065] In some embodiments of the present invention, the connecting frame 6 and the mounting frame 7 are connected by a support frame 8. The support frame 8 includes a first support plate 81 and a second support plate 82. The plane where the first support plate 81 is located is perpendicular to the plane where the second support plate 82 is located. The first support plate 81 is connected to the connecting frame 6, and the second support plate 82 is connected to the mounting frame 7.

[0066] Specifically, the dishwasher's connecting frame 6 and mounting frame 7 are connected by a support frame 8. The support frame 8 includes a first support plate 81 and a second support plate 82, positioned such that the plane of the first support plate 81 is perpendicular to the plane of the second support plate 82. The first support plate 81 is connected to the connecting frame 6, and the second support plate 82 is connected to the mounting frame 7. The function of the support frame 8 is to provide stable support and connection. The connection between the first support plate 81 and the connecting frame 6 ensures the stability and fixed position of the connecting frame 6, while the connection between the second support plate 82 and the mounting frame 7 ensures the stability of the mounting frame 7. Through this connection method, forces can be transferred and loads can be borne between the connecting frame 6 and the mounting frame 7, thereby maintaining the structural stability and reliability of the entire dishwasher. By adopting this design of connecting frame 6, mounting frame 7, and support frame 8 in the dishwasher, the following technical effects can be achieved: ensuring a stable connection between the connecting frame 6 and the mounting frame 7, providing support and fixation functions, enhancing the structural strength and stability of the dishwasher, increasing the service life of the dishwasher, and reducing the failure rate.

[0067] Optionally, the first support plate 81 and the second support plate 82 are integrally formed to ensure the stability of the structure.

[0068] In some embodiments of the present invention, the first connecting plate 61 is provided with at least one first positioning hole 611, the second support plate 82 is provided with at least one second positioning hole 821, the mounting bracket 7 is connected to the connecting bracket 6 through the first positioning hole 611, and the mounting bracket 7 is connected to the support bracket 8 through the second positioning hole 821.

[0069] Specifically, the first connecting plate 61 has a first positioning hole 611, and the second support plate 82 has a second positioning hole 821. Through these positioning holes, the mounting bracket 7 is connected to the connecting bracket 6 and the support bracket 8. Specifically, the mounting bracket 7 is connected to the connecting bracket 6 through the first positioning hole 611 and to the support bracket 8 through the second positioning hole 821. This variant of the structure enables stable connection and support of the dishwasher, ensuring the correct position and interaction of each component. The structural design of the connecting bracket 6 and the mounting bracket 7 makes the assembly and disassembly of the dishwasher more convenient and efficient. The presence of the support bracket 8 further enhances the overall stability and structural strength of the dishwasher.

[0070] In addition, by providing some positioning holes on the first connecting plate 61 and the second support plate 82, accurate reference points can be provided for positioning and fixing the connecting frame 6. The function of the positioning holes is to determine the position of the connecting parts and ensure accurate alignment of the connection. When the connecting frame 6 is inserted into some positioning holes, the position of these positioning holes will guide the connecting frame 6 to correctly align with the connection point, thus ensuring the stability, accuracy and reliability of the connection. The first positioning hole 611 and the second positioning hole 821 provide basic planar positioning, allowing the connecting frame 6 to align with the connection point in two directions. If higher accuracy and stability are required, the number of positioning holes can be increased. These positioning holes are located at the edges, corners or other important feature points of the connecting frame 6.

[0071] In some embodiments of the present invention, a limiting block 9 is fixed on the first connecting plate 61 to prevent the rotating arm 32 from shifting. The limiting block 9, the rotating arm 32, the first connecting plate 61 and the third mounting plate 73 are intersected and a rotating axis is provided at the intersection. The rotating arm 32 can rotate around the rotating axis.

[0072] Specifically, a limit switch is fixedly installed on the first connecting plate 61 to prevent the rotating arm 32 from shifting. It is a fixed block element that ensures that the rotating arm 32 rotates within a limited range. The rotation axis is located at the intersection of the rotating arm 32, the first connecting plate 61 and the third mounting plate 73. It is the central axis around which the rotating arm 32 rotates. This structure can ensure that the rotating arm 32 rotates in the correct position and remains stable and reliable during operation.

[0073] In some embodiments of the present invention, the body 1 includes an outer shell and an inner shell, the inner shell forms a cleaning chamber, the outer shell and the inner shell are connected by a limiting connecting plate, the outer shell, the inner shell and the limiting connecting plate form a cavity, and the door lock device 3 is disposed in the cavity.

[0074] Specifically, the main body 1 is the core structure of the dishwasher, comprising an outer shell and an inner shell. The outer shell is the visible external surface of the dishwasher and can be aesthetically pleasing according to the overall design. The inner shell is located inside the dishwasher and is typically made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel. The cleaning chamber formed by the inner shell is the working area of ​​the dishwasher, used to accommodate tableware and utensils, and to withstand washing, rinsing, and drying operations. Between the outer and inner shells is a hidden space, or cavity, for installing internal components of the dishwasher or the door lock device 3. An opening is provided in the cleaning chamber, and the door panel 1 is a rotating structure connected to the main body 1 for opening and closing this opening. The dishwasher door lock device 3 is located within the hidden space between the outer and inner shells, forming a cavity, thus concealing the door lock device 3 and enhancing the dishwasher's aesthetic appeal and overall design.

[0075] The dishwasher door lock device 3 is installed in the concealed space between the outer and inner shells, making the door lock device 3 invisible and improving the appearance and overall look of the dishwasher. When the door panel 1 is open, the rotating arm 32 is in the first position 4, and the rotating arm 32 abuts against the limiting connecting plate. The limiting connecting plate serves to limit the rotating arm 32 and also bears the load. At this time, when the door panel 1 is open, the door panel 1 is connected to the rotating arm 32, and the rotating arm 32 exerts a pulling force on the door panel 1 to prevent the door panel 1 from continuing to rotate downward, so that the position of the door panel 1 remains parallel to the horizontal plane.

[0076] The present invention provides a limiting elastic element 31 and a rotating arm 32 to ensure that the door panel 1 provides better tightness when closed. The door panel 1 remains firmly locked in the closed state, thereby preventing accidental opening and allowing easy operation when open, thus improving the safety and convenience of the dishwasher.

[0077] The above are merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
