Description

Technical Field

[0001] This invention belongs to the field of dishwashers, and more specifically, relates to a box assembly and a dishwasher having the box assembly. Background Technology

[0002] Dishwashers are kitchen appliances, and in the humid and oily environment of a kitchen, they require a good sealing structure and reliable operation. Touchscreen displays are electrical components, which are also easily affected by grease and moisture. Therefore, to ensure their normal and long-term reliable use, good sealing of the electrical components is essential; otherwise, they may become unresponsive or even malfunction.

[0003] In existing technology, to reduce moisture ingress into the touch panel, the touch panel is first assembled into a display box, then a rubber seal is assembled onto the display box, and finally, the entire assembly is inserted into the dishwasher. The touch panel's terminals are then pulled out and plugged into another control board. This solution has the following problems: First, because the rubber seal and the display box are assembled together, and to ensure a good seal, there must be very little space between the display box and the dishwasher. This means that during insertion, the rubber seal can easily become misaligned or detach from the display box, losing its sealing function. Second, to bring out the touch panel's terminal wires, holes must be drilled in the display box, which can also become channels for moisture ingress, resulting in poor moisture sealing of the display box.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a box assembly with good sealing effect.

[0006] Another object of the present invention is to provide a dishwasher having a box assembly.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a box assembly, including a box body, wherein a notch is provided on the side wall of the box body, and a sealing element is provided on the side wall of the box body;

[0008] The sealing element includes a first sealing element disposed on the top of the side wall of the housing and a second sealing element disposed on the notch, wherein the first sealing element is connected to the second sealing element.

[0009] This invention provides a first sealing element on the top of the side wall of the housing, forming a sealed connection during assembly with other components. This prevents moisture, oil, and other contaminants from entering the housing and damaging the internal control board. Simultaneously, a second sealing element is placed within a notch for wiring. This second sealing element mates with the control board's connection wires, preventing moisture and oil from entering the housing through the notch, further improving the sealing performance during housing assembly. The connection between the first and second sealing elements prevents them from detaching during housing assembly, facilitating installation and enhancing the overall sealing performance after assembly.

[0010] This invention provides a sealed and stable box assembly.

[0011] Furthermore, the first seal and the second seal are an integral structure;

[0012] Preferably, the seal and the box body are an integral structure.

[0013] This invention provides a box assembly that is easy to install.

[0014] Furthermore, the second seal matches the notch, and the second seal is provided with a threading hole.

[0015] Furthermore, the second seal is provided with at least two through holes, which are interconnected.

[0016] Furthermore, the second seal has a groove extending downward from the top on one side of the box body, and the groove communicates with the wire hole;

[0017] Preferably, the groove is provided along the height direction of the side wall of the box.

[0018] Furthermore, the second seal has a slit extending downward from the top, the slit communicating with the thread hole.

[0019] The present invention also includes a dishwasher having a cassette assembly as described in any of the above descriptions.

[0020] Furthermore, it also includes an electronic control board, and the inner wall of the box is provided with a support member that is higher than the bottom wall. The electronic control board and the support member are installed in the box.

[0021] Furthermore, it also includes an electronic control board connection wire, one end of which is connected to the electronic control board inside the box, and the other end passes through the second seal to the outside of the box.

[0022] Furthermore, the dishwasher includes an inner tub and a flange structure disposed on the outer edge of the opening of the inner tub. The flange structure has a mounting part on the side opposite to the opening of the inner tub. The box assembly is installed on the flange structure in cooperation with the mounting part, and the opening of the box body is installed facing the flange structure.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] (1) This invention, by providing a first sealing element on the top of the side wall of the box, forms a sealed connection when the opening of the box is assembled with other structures, preventing moisture, oil, and other contaminants from entering the interior of the box and damaging the electrical control board inside. Simultaneously, a second sealing element is provided within the notch, which can cooperate with the electrical control board connection wires extending from the box, preventing moisture and oil from entering the box through the notch, further improving the sealing performance during box assembly installation. The connection between the first and second sealing elements prevents the sealing elements from falling off during box assembly installation, facilitating the installation of the box assembly and improving the sealing performance after installation.

[0025] (2) The present invention installs the box assembly on the flange structure with the opening of the box facing the flange structure, so that the sealing element is installed in conjunction with the flange structure to complete the sealing of the box assembly, thereby preventing water vapor or oil from entering from the opening of the box and the gap for wiring, and improving the sealing performance of the box assembly after installation.

Therefore, they should not be construed as limiting this invention.

[0039] 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figures 1 to 7As shown, the present invention provides a box assembly, including a box body 2, a notch 21 on the side wall of the box body 2, and a sealing member 3 on the side wall of the box body 2; the sealing member 3 includes a first sealing member 31 disposed on the top of the side wall of the box body 2, and a second sealing member 32 disposed on the notch 21, wherein the first sealing member 31 and the second sealing member 32 are connected.

[0041] The present invention provides a first sealing element 31 on the top of the side wall of the housing 2. The first sealing element 31 can form a sealed connection when assembled with other structures, which can prevent moisture, oil and other contaminants from entering the interior of the housing 2. At the same time, a second sealing element 32 is provided in the notch 21 for wire threading. The second sealing element 32 can cooperate with the electrical control board connection wire 4 that passes through the housing 2, which can prevent moisture and oil contaminants from entering the housing 2 through the notch 21, further improving the sealing performance of the housing assembly during installation.

[0042] The box assembly described in this invention can be used in home appliances such as dishwashers, washing machines, range hoods, and refrigerators. When the box assembly is assembled with the home appliance, it forms a seal to prevent moisture, oil, etc. from entering the box body 2 through the opening and the notch 21. The first sealing member 31 and the second sealing member 32 are integrally connected, which can prevent the sealing member 3 from falling off during the installation of the box assembly, facilitate the installation of the box assembly, and improve the sealing performance of the box assembly after installation.

[0043] Preferably, the first sealing element 31 and the second sealing element 32 are integrally formed. The sealing element 3 and the housing 2 are integrally formed. The sealing element 3 has a certain degree of elasticity. Preferably, the sealing element 3 and the housing 2 can be integrally formed by a two-material injection molding process. Because the sealing element 3 and the housing 2 are integrally formed, the connection strength between the sealing element 3 and the housing 2 is very high. Therefore, when the housing assembly is installed, the sealing element 3 will not fall off the housing 2 under external pressure, and will not cause poor sealing of the installed housing assembly.

[0044] Alternatively, an installation groove (not shown in the figure) may be provided on the top of the side wall of the box body 2 or in the notch 21, and the seal 3 may have an installation structure that matches the installation groove. By installing the seal 3 in the installation groove of the box body 2, the problem of the seal 3 easily falling off during the installation of the box assembly can be prevented.

[0045] like Figure 1 and Figure 2As shown, the second sealing element 32 matches the notch 21, and the second sealing element 32 is provided with a wire-passing hole 321. The size and shape of the second sealing element 32 match the notch 21. The wire-passing hole 321 is used for threading wires and cooperates with the electrical control board connection wire 4 for sealing. The wire-passing hole 321 matches the electrical control board connection wire 4. Preferably, the bottom of the second sealing element 32 is disposed within the notch 21, and the top of the second sealing element 32 is in the same plane as the top of the first sealing element 31.

[0046] Existing housings use holes in the side walls through which the control board connection wires pass. This creates a gap between the holes and the connection wires, making it easy for moisture and oil to enter. The present invention addresses this by incorporating a second sealing element 32 on the wire-passing notch 21, with a wire-passing hole 321 on the second sealing element 32. Since the sealing element 32 and the control board connection wire 4 can cooperate to seal, moisture and oil are prevented from entering the housing 2 through the notch 21, further improving the sealing performance of the housing assembly during installation.

[0047] Furthermore, the second sealing element 32 is provided with at least two through holes 321, which are interconnected. Preferably, the through holes 321 are evenly spaced along the height direction of the side wall of the housing 2. The number of through holes 321 matches the number of wires of the control board connection wire 4. In existing systems, especially when the control board connection wire 4 is a terminal wire, the holes on the housing need to be large enough for the terminal wire to pass through, thus the gap between the hole and the terminal wire is very easy for moisture and oil to enter. In this invention, because the through holes 321 on the sealing element 3 are interconnected, the control board connection wire 4, when it is a terminal wire, can pass through the interconnected through holes 321, while ensuring the sealing of the wiring structure of the housing 2. The through holes 321 can also serve to position the control board connection wire 4.

[0048] like Figure 3 As shown, the second sealing member 32 has a groove 322 extending downward from the top on one side inside the box body 2, and the groove 322 communicates with the wire hole 321; preferably, the groove 322 is arranged along the height direction of the side wall of the box body 2.

[0049] By providing a groove 322 extending downward from the top on the inner side of the second seal 32, when the control board connection wire 4 is installed, especially when the control board connection wire 4 is a terminal wire, a blade can be used to cut along the groove 322 to form an opening 323 communicating with the wire hole 321. When installing the control board connection wire 4, the control board connection wire 4 can be inserted into the wire hole 321 from the top along the opening 323.

[0050] Alternatively, the second seal 32 may have a slit 323 extending downward from the top, the slit 323 communicating with the wire hole 321. Preferably, the slit 323 is disposed within the groove 322, extending along the groove 322. When installing the control board connecting wire 4, the control board connecting wire 4 can be inserted from the top along the slit 323 into the wire hole 321.

[0051] The present invention also provides a dishwasher having the aforementioned cassette assembly. (As described above) Figure 4 As shown, the box assembly is mounted on the inner tub 6 of the dishwasher.

[0052] The dishwasher of the present invention also includes an electronic control board 1 (see reference). Figure 5 The inner wall of the box 2 is provided with a support member 22 that is higher than the bottom wall (see reference). Figure 1 The electronic control board 1 is installed inside the housing 2 in conjunction with the support member 22. The electronic control board 1 is mounted on the support member 22.

[0053] like Figure 5 As shown, the dishwasher also includes an electronic control board connecting wire 4. One end of the electronic control board connecting wire 4 is connected to the bottom of the electronic control board 1 inside the housing 2, and the other end passes through the second sealing member 32 to the outside of the housing 2. The electronic control board 1 can be fixed in the housing 2 by means of snap-fit, screw-fit, adhesive, etc.

[0054] The present invention provides a support member 22 on the inner wall of the box body 2 that is higher than the bottom wall, and installs the electronic control board 1 on the support member 22. This allows for a certain distance between the electronic control board 1 and the bottom wall of the box body 2, providing space for the installation of the electronic control board connection line 4.

[0055] The dishwasher of the present invention includes an inner tub 6 and a flange structure 5 disposed on the outer edge of the opening of the inner tub 6 (see reference). Figure 4 The flange structure 5 is provided with a mounting part 51 on the side opposite to the opening of the inner liner 6 (see reference). Figure 6 The box assembly is mounted on the mounting part 51 and fitted onto the flange structure 5, with the opening of the box body 2 facing the flange structure 5.

[0056] This invention installs the box assembly on the flange structure 5, with the opening of the box body 2 facing the flange structure 5. After the sealing element 3 is installed in conjunction with the flange structure 5, the box assembly is sealed, preventing moisture or oil from entering through the opening of the box body 2 and the wire-threading notch 21, thus improving the sealing performance of the box assembly after installation.

[0057] Figure 7 This is a partial schematic diagram of the flange structure of the present invention on the side opposite to the inner liner opening, as shown below. Figure 7As shown, a mounting portion 51 is provided on the side of the flange structure 5 opposite to the inner liner opening. The mounting portion 51 includes a connector protruding from the flange structure 5. The connector cooperates with the flange structure 5 to form a mounting cavity, and the box assembly is installed in the mounting cavity. Preferably, the connector is a bracket, and the box assembly can be inserted and pulled out along the bracket to be pressed and sealed with the flange structure 5.

[0058] The connector includes a first connector 512 and a second connector 513. The second connector 513 is provided with mounting holes for fixing the box assembly.

[0059] Furthermore, the mounting portion 51 includes a vertical wall 511 protruding from the flange structure 5, the vertical wall 511 matching and fitting with the opening of the housing 2. The height of the vertical wall 511 matches the height of the sealing element at the top of the side wall of the housing 2, and the sealing element 3 is interference-fitted with the vertical wall 511, which can improve the sealing performance of the housing assembly. Preferably, the electronic control board 1 is a display board.

[0060] The first connector 512 is disposed on one side wall of the vertical wall 511, and the second connector 513 is disposed on the side wall of the vertical wall 511 adjacent to the first connector 512. Preferably, the sealing member 3 is interference-fitted with the mounting part 51.

[0061] The flange structure 5 is provided with a light-transmitting hole 52, and the light emitted by the electronic control board 1 is displayed on the side of the flange structure 5 corresponding to the opening of the inner liner through the light-transmitting hole 52.
