Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, and in particular to a dishwasher. Background Technology

[0002] Dishwashers integrate washing, sanitizing, drying, and storage functions, not only changing the traditional hand washing method but also offering advantages such as attractive appearance, ease of use, time and labor saving, and hygienic cleaning, making them increasingly popular among consumers. The working principle of a dishwasher is that a motor drives a washing pump to spray detergent under pressure from a spray nozzle, forming a dense three-dimensional hot water stream. The spray nozzle rotates due to the reaction force of the sprayed water, evenly spraying the detergent onto the dishes inside the dishwasher, providing a three-dimensional spray rinse and scrub.

[0003] Dishwasher bases typically house a heating element, and an electrical control box is mounted on the base. This control box contains a circuit board electrically connected to the heating element and the motor that drives the wash pump, enabling the dishwasher to perform washing, drying, and sanitizing according to pre-set programs. For ease of wiring installation and maintenance, the control box is usually placed flat at the bottom of the base. However, the presence of the motor, water pump, and heating element increases the base's height and size. Furthermore, placing it flat at the bottom makes it susceptible to interference from surrounding components. Especially considering that current dishwashers incorporate overflow devices at the bottom of the base to prevent water leakage, a flat installation of the control box is unsuitable.

[0004] Prior art CN202220722914.9 discloses a dishwasher, including a base and an electronic control box mounted on the base. The base frame includes a bottom wall and a side wall, and the base frame also includes a positioning groove, a first limiting part, and a second limiting part. The positioning groove is disposed near one end of the side wall, and one end of the electronic control box is inserted into the positioning groove along the extending direction of the side wall. The first limiting part is disposed opposite to the side wall, and the electronic control box is limited between the first limiting part and the side wall. The second limiting part is disposed opposite to the positioning groove, and the second limiting part cooperates with the electronic control box to prevent the electronic control box from coming out of the positioning groove.

[0005] In the prior art, the control box is installed by extending along the side wall, which is a vertical insertion method. Compared with removing screws with tools, this reduces the difficulty of disassembling the control box. However, for the entire base of the dishwasher, after the control box is installed, other components are continuously installed on top of the base. This means that when the control box needs to be disassembled for maintenance after the installation of the control box and the overall structure of the dishwasher is completed, the components on the upper side of the control box need to be removed so that the control box can be removed through the insertion direction. This increases the difficulty of disassembling and assembling the control box for maintenance. Utility Model Content

[0006] The purpose of this invention is to provide a dishwasher that solves the problem of increased disassembly and assembly difficulty and wasted maintenance costs caused by the vertical installation of the control box. This invention reduces the difficulty of disassembling and assembling the control box, thereby reducing the maintenance cost of the control box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a dishwasher, including a base and a base plate box mounted on the base, the base including a side frame extending in the height direction, the side frame having a cavity for receiving the base plate box, the base plate box being placed sideways in the cavity, and the outer side of the side frame providing a lateral opening for the base plate box to be inserted into or removed from the cavity.

[0008] After adopting the above technical solution, the present invention has the following advantages: a side frame with a height extension is provided on the base, and a cavity and a lateral opening on the outer side of the side frame for loading and unloading the base plate box are provided on the side frame. This allows the installation and disassembly of the base plate box to be carried out through the lateral opening on the outer side of the side frame. When the base plate box is damaged and needs to be disassembled for repair, it is not necessary to remove other components of the dishwasher above the side frame, which reduces the difficulty of disassembly and assembly during base plate box repair. Furthermore, when assembling the dishwasher, it is not necessary to assemble the base, side frame, base plate box, and other components above the base plate box in a certain order, which reduces the assembly difficulty of the dishwasher, improves the assembly efficiency of the dishwasher, reduces the disassembly and assembly difficulty of the base plate box, and reduces the maintenance cost of the base plate box.

[0009] Furthermore, the bottom wall of the cavity has an upwardly extending positioning threshold, and the bottom surface of the substrate box has a positioning groove that matches the positioning threshold. The matching of the positioning threshold and the positioning groove allows the substrate box to rotate relative to the side frame during assembly and disassembly.

[0010] Using the aforementioned technical solution, after the substrate box is housed in the cavity, the positioning groove and positioning threshold cooperate to allow the substrate box to rotate relative to the side frame during installation. The rotating installation method can reduce the space of the cavity and reduce the risk of the substrate box shaking after installation due to an excessively large cavity space, which would affect the stability of the substrate box after installation.

[0011] Furthermore, the dishwasher includes an openable and closable door, and a spring for assisting in closing the door is provided on the side frame, the spring being inserted into the cavity formed by the positioning threshold.

[0012] Using the aforementioned technical solution, the dishwasher door is closed with the assistance of a spring, reducing the difficulty of closing the door. After the spring is set, it is located in the cavity surrounded by the positioning threshold. The positioning threshold not only surrounds the spring but also supports the base plate box.

[0013] Furthermore, the substrate box is supported on the upper surface of the positioning threshold, and a drainage gap is reserved between the lower surface of the substrate box and the bottom wall of the cavity.

[0014] With the aforementioned technical solution, after the substrate box is housed in the cavity and supported on the upper surface of the positioning threshold, a drainage gap is reserved between the lower surface of the substrate box and the bottom wall of the cavity, which facilitates the drainage of water inside the side frame and prevents water from accumulating inside the side frame and affecting the normal use of the dishwasher.

[0015] Furthermore, the positioning sill is provided with an overflow hole that connects to the cavity.

[0016] By adopting the aforementioned technical solution, the water in the cavity flows out through the overflow hole on the positioning threshold, preventing water from accumulating in the cavity, reducing the possibility of the substrate box being soaked in water in the cavity, and reducing the possibility of damage to the substrate box.

[0017] Furthermore, the top wall of the positioning threshold is provided with a rib, which blocks the outside of the base plate box.

[0018] By adopting the aforementioned technical solution, the raised ribs formed on the outer wall of the positioning threshold prevent the substrate box from detaching from the cavity, thereby further improving the stability of the substrate box within the cavity.

[0019] Furthermore, a gap is reserved between the top wall of the cavity and the top wall of the substrate box to avoid the substrate box during rotation and disassembly.

[0020] By adopting the aforementioned technical solution, a gap is reserved between the top wall of the cavity and the top wall of the substrate box. When rotating and disassembling the substrate box, the gap avoids the substrate box, preventing wear and damage between the substrate box and the top wall of the cavity, thus making the installation and disassembly of the substrate box smoother.

[0021] Furthermore, the side frame is provided with a supporting side plate, which is located outside the substrate box. The supporting side plate and the substrate box at least partially overlap in the front-back direction to block the substrate box within the cavity.

[0022] By adopting the aforementioned technical solution, the substrate box is blocked within the cavity by the supporting side plate, which avoids the possibility of the substrate box shaking within the cavity or leaving the cavity during transportation, thereby improving the stability of the substrate box.

[0023] Furthermore, the lower side of the support side plate is connected to the base via a buckle, and the upper side is fastened to the side frame via fasteners.

[0024] By adopting the aforementioned technical solution, the lower side of the support side plate is stably connected by a snap-fit, and the upper side is fastened by a fastener, which further improves the stability of the support side plate, prevents the support side plate from detaching from the side frame and affecting the stability of the substrate box, reduces the deviation of the support side plate from the substrate box after it is fixed, and further improves the stability of the substrate box in the cavity.

[0025] Furthermore, the supporting side plate is a metal plate, and the supporting side plate is in contact with the base plate box.

[0026] By adopting the aforementioned technical solution, the support side is set as a metal plate, and the support side is in contact with the base plate box to assist in heat dissipation during the operation of the base plate box. Attached Figure Description

[0038] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0039] like Figures 1 to 5 As shown, this utility model provides a dishwasher, including a base 1 and a base plate box 3 installed on the base 1. The base 1 includes a side frame 2 extending in the height direction. A drive component is installed in the middle part of the base 1. The drive component is generally a motor, a water pump, and a heating device. The motor drives the water pump to generate washing power. When the heating device is working, it dries and disinfects the washed tableware. The side frame 2 has a cavity 21 for receiving the base plate box 3. A circuit board is provided inside the base plate box 3. The circuit board is electrically connected to the motor, water pump, and heating device, so that the dishwasher can perform washing, drying, and disinfection according to the set program, reducing the difficulty of manual cleaning and making tableware cleaning convenient and automated, reducing the trouble of manual cleaning. The outer side of the side frame 2 provides a lateral opening 211 for the base plate box 3 to be inserted into or removed from the cavity 21. When disassembling or assembling the base plate box 3, it is done through the lateral opening 211 of the cavity 21. It is not necessary to disassemble other components of the dishwasher located on the upper side of the base plate box 3, reducing the disassembly difficulty of the base plate box 3 during maintenance and disassembly, thereby reducing the maintenance cost of the base plate box 3.

[0040] In this embodiment, as Figure 1As shown, the bottom wall of the cavity 21 has an upwardly extending positioning threshold 22, and the bottom surface of the substrate box 3 has a positioning groove 31 that mates with the positioning threshold 22. Specifically, the substrate box 3 includes an outer side surface 311 and a lower end surface 312. The connection between the outer side surface 311 and the lower end surface 312 is recessed inward to form the positioning groove 31. The engagement of the positioning threshold 22 and the positioning groove 31 allows the substrate box 3 to rotate relative to the side frame 2 during assembly and disassembly. Specifically, when installing the substrate box 3, as follows... Figure 1 , Figure 2 and Figure 3 As shown, after the outer edge of the top wall of the positioning groove 31 abuts against the positioning threshold 22, the base plate box 3 rotates, and the upper side of the base plate box 3 enters the cavity 21 as the base plate box 3 rotates. When the base plate box 3 needs to be disassembled, the installer or maintenance personnel pull the base plate box 3 upward, and the lower side of the base plate box 3 moves upward a small range relative to the positioning threshold 22. Then, the base plate box 3 is rotated outward and pulled to remove it from the cavity 21. The installation and disassembly of the base plate box 3 only require pulling the base plate box 3. During the maintenance of the base plate box 3, it is not necessary to disassemble other components of the dishwasher above the side frame 2, thereby reducing the difficulty of installing or disassembling the base plate box 3 and thus reducing the maintenance cost of the base plate box 3.

[0041] In this embodiment, as Figure 3 and Figure 4 As shown, in order to facilitate the rotation and installation of the substrate box 3 into the cavity 21, a gap 23 is reserved between the top wall of the cavity 21 and the top wall of the substrate box 3. The gap 23 is used to avoid the substrate box 3 during rotation and disassembly, so as to avoid wear and damage between the substrate box 3 and the top wall of the cavity 21, making the installation and disassembly of the substrate box 3 smoother.

[0042] In another embodiment, such as Figure 6 As shown, the dishwasher includes an openable and closable door 11. A spring is provided on the side frame 2 to assist in closing the door 11. The spring is inserted into the cavity formed by the positioning threshold 22. The positioning threshold 22 supports the base box 3 and also surrounds the spring, thereby increasing the use of the positioning threshold 22, reducing the structure on the base 1 and the side frame 2, and reducing the manufacturing difficulty of the base 1 and the side frame 2.

[0043] To reduce the possibility of the substrate box 3 detaching from the cavity 21, such as Figure 4 As shown, the top wall of the positioning threshold 22 is provided with a rib 221. The rib 221 protrudes upward. After the substrate box 3 is installed in the cavity 21, the rib 221 blocks the outside of the substrate box 3. The blocking position of the rib 221 is higher than the top wall of the positioning threshold 22. The rib 221 increases the blocking range of the positioning threshold 22, thereby improving the stability of the substrate box 3 in the cavity 21.

[0044] To further improve the stability of the substrate cell 3 in the cavity 21, such as Figure 6 and Figure 7As shown, the outer side of the side frame 2 has a fixing groove 24. The fixing groove 24 and the cavity 21 at least partially overlap in the front-back direction. A support side plate 4 is detachably provided at the fixing groove 24. After the support side plate 4 is installed in the fixing groove 24, the support side plate 4 and the substrate box 3 partially overlap in the front-back direction, so that the support side plate 4 blocks the substrate box 3 in the cavity 21, thereby improving the stability of the substrate box 3 in the cavity. The support side plate 4 and the substrate box 3 can also completely overlap in the front-back direction, increasing the range of the support side plate 4 blocking the substrate box 3 on the outside, thereby improving the stability of the substrate box 3.

[0045] In this embodiment, in order to improve the stability of the supporting side plate 4, such as Figure 7 and Figure 8 As shown, the inner wall of the fixing groove 24 is provided with a limiting post 241, which passes through the supporting side plate 4 to position the supporting side plate 4; furthermore, the upper side of the supporting side plate 4 is fixed to the side frame 2 by fasteners 42, and the lower side is connected to the base 1 by buckles, thereby improving the stability of the upper and lower sides of the supporting plate. When installing the support side plate 4, a snap-fit ​​piece 41 is provided on the lower side of the support side plate 4. The snap-fit ​​piece 41 has a snap-fit ​​interface 411. A protrusion 412 is provided on the side frame 2. The protrusion 412 extends inward and the snap-fit ​​piece 41 is inserted inward, so that the snap-fit ​​interface 411 on the snap-fit ​​piece 41 snaps with the protrusion 412. The snap-fit ​​interface 411 and the protrusion 412 are sleeved to form a buckle, thereby stabilizing the lower side of the support side plate 4. After the lower side of the support side plate 4 is snapped, the support side plate 4 is rotated upward and sleeved on the limiting post 241. After the limiting post 241 is positioned, the fastener 42 is used to fasten the connection. After the support side plate 4 is fixed, the base plate box 3 is pressed inward, thereby improving the stability of the base plate box 3.

[0046] To improve the heat dissipation of the substrate box 3, the support side plate 4 is a metal plate. After the support side plate 4 is installed in the fixing groove 24, it contacts the outer side wall of the substrate box 3 to assist in the heat dissipation of the substrate box 3 and reduce the possibility of overheating of the substrate box 3.

[0047] In another embodiment, such as Figure 4 and Figure 6 As shown, to reduce the possibility of water accumulating on the inner side of the side frame 2, the side frame 2 is provided with multiple overflow holes 26, such as... Figure 4 As shown, the overflow hole 26 at the cavity 21 is located at the positioning threshold 22. After the substrate box 3 is supported on the upper end surface of the positioning threshold 22, the lower end surface of the substrate box 3 and the bottom wall of the cavity 21 are reserved with a drainage gap 251. The positioning threshold 22 is provided with an overflow hole 26 that connects to the cavity 21. The inner space of the side frame 2, the drainage gap 251 and the overflow hole 26 are connected to form an overflow channel, which makes it easy for the accumulated water to flow out from the cavity 21 to the outside of the side frame 2, thereby reducing the possibility of water accumulating on the inside of the side frame 2.

[0048] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
