Description

Technical Field

[0001] This application relates to the field of kitchen appliances technology, and more particularly to an installation structure for a dishwasher. Background Technology

[0002] With the development of technology, more and more families are choosing dishwashers to wash their dishes. Dishwashers not only effectively clean dishes but also dry them after cleaning, preventing bacteria from growing inside. To protect the inner drum of the dishwasher, a casing is usually installed on the outside. The outer casing of a dishwasher generally consists of side panels and a top cover, with the top cover and the two side covers fixed together by bolts or other fasteners. However, when users need to open the casing to inspect the interior, tools are required, making the operation relatively complicated.

[0003] In existing technologies, the inner tub and base are mostly fixedly connected by a locking mechanism of slots and blocks or by bolts. Since the inner tub is mostly embedded, even a slight misalignment can prevent the blocks from properly inserting into the slots. Furthermore, removing the inner tub from the base is quite cumbersome. Therefore, there is an urgent need for a simple and quick dishwasher installation structure. Utility Model Content

[0004] One objective of this application is to provide an installation structure for a dishwasher that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a dishwasher installation structure, including an inner tub and a base, wherein the inner tub is installed on the base; a housing assembly is provided on the outer side of the inner tub, the housing assembly including a top cover and two side plates, the two side plates being respectively installed on both sides of the inner tub, and the top cover being installed on the top of the inner tub; the top ends of the side plates are folded inward to form a mounting plate, the mounting plate being provided with a water droplet hole, the top cover being provided with a locking block, and the length of the water droplet hole being greater than the length of the locking block, the locking block being slidably engaged with the narrow section of the water droplet hole.

[0006] The above setup further improves the speed of top cover installation and removal. The top cover is slidably installed above the side panel. The user simply inserts the locking block into the teardrop hole, then slides the top cover horizontally, causing the locking block to slide to the narrow section of the teardrop hole to limit the top cover's position. If the user needs to remove the top cover, simply slide the top cover in the opposite direction to cause the locking block to slide to the wide section of the teardrop hole, and then remove the top cover.

[0007] Preferably, there are multiple water droplets and multiple locking blocks, with the water droplets sequentially arranged on the mounting surface and the multiple locking blocks sequentially arranged on the top cover. This arrangement can further improve the stability of the top cover installation, and the cooperation of multiple water droplets and locking blocks can prevent the top cover from warping.

[0008] Preferably, the locking block is L-shaped, and it engages with the end face of the top cover to form a locking cavity, the width of which gradually decreases from the outside to the inside. The locking cavity is used to limit the top cover in conjunction with the mounting plate. With this configuration, when the locking block reaches the narrow section of the teardrop hole, the mounting plate is embedded in the locking cavity, allowing the mounting plate to axially limit the locking block.

[0009] Preferably, the inner liner is also equipped with a baffle strip, which is perpendicularly connected to the side panels on both sides. The baffle strip is provided with a limiting groove, and the top cover is provided with a limiting block for engaging with the limiting groove. This configuration allows the top cover to be positioned by the limiting groove and the limiting block. When the top cover is installed, the limiting block extends into the limiting groove, further improving the positioning effect and preventing the top cover from falling off when the dishwasher shakes.

[0010] Preferably, the side of the top cover away from the limiting groove is folded downward to form a baffle. With this configuration, once the top cover is installed, the baffle can limit the movement of the side panels on both sides, thereby preventing the side panels from tilting.

[0011] Preferably, the base is provided with a boss, the lower parts of the two side plates are connected to the boss, and the upper parts of the two side plates are connected by a connector. This arrangement can further improve the stability of the side plates, and the connector can work with the boss to limit the distance between the two side plates, ensuring that the positions of the two side plates do not change when the top cover is moved.

[0012] Preferably, a locking structure is provided between the boss and the inner liner, the locking structure being used to lock the position of the inner liner. This configuration can further improve the stability of the inner liner installation.

[0013] Preferably, the locking structure includes a side lug and a baffle. The side lug is located on the side of the inner liner, and the baffle is installed on the boss. The baffle is used to lock the inner liner in conjunction with the side lug. With this configuration, when the inner liner is placed on the base, the upper surface of the boss and the upper surface of the side lug are on the same horizontal plane. Then, the baffle is fixedly installed on the upper surface of the boss, ensuring that the baffle portion is above the side lug, thus limiting the inner liner's installation on the base.

[0014] Preferably, the device also includes a door body, with a locking rod assembly installed on the inner liner and a latch assembly on the door body. The locking rod assembly is used to cooperate with the latch assembly to lock / unlock the door body. With this configuration, when the door body is closed, the locking rod assembly and the latch assembly engage to lock the door body in place, preventing the door from opening due to vibration during dishwasher operation.

[0015] Preferably, the locking rod assembly includes a housing and a sliding rod. The housing has a sliding groove, and the sliding rod is slidably mounted in the sliding groove, with the sliding rod inclined downwards along the direction of the latch assembly. The latch assembly includes a bracket and a locking hook. The bracket is mounted on the door body, and the locking hook is rotatably mounted on the bracket. The sliding rod has a locking hole for engaging the locking hook. With this configuration, when the door needs to be closed, the locking hook engages the locking hole, and the sliding rod retracts into the housing, causing the door to rotate in the closing direction. When the door needs to be opened, the sliding rod extends out of the housing, causing the door to rotate in the opening direction. Furthermore, the downward-inclined arrangement of the sliding rod increases the gap when the door is opened and allows the sliding rod to adapt to the height difference between the door and the housing, extending the service life of the sliding rod.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] In this invention, the top cover is slidably mounted above the side panel, and the top cover and side panel are connected by a quick-connect and quick-release mechanism, which effectively reduces the difficulty of opening the top cover. Inserting the locking block into the teardrop hole and then sliding the top cover to the narrow section of the teardrop hole limits the position of the top cover. When the user needs to remove the top cover, simply sliding the top cover in the opposite direction allows the locking block to slide to the wide section of the teardrop hole, releasing the restriction on the top cover.

[0018] The baffle is detachably installed on the boss. When the baffle is fixedly installed on the boss, the baffle and the side ear have overlapping surfaces, so that the baffle can block the side ear, thereby limiting the installation of the inner liner on the base. This utility model has the advantages of simple structure and convenient installation. Attached Figure Description

[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0034] One aspect of this application provides a dishwasher mounting structure, one preferred embodiment of which is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes an inner liner 100 and a base 1, with the inner liner 100 mounted on the base 1. A housing assembly for protecting the inner liner 100 is provided on the outer side of the inner liner 100. The housing assembly includes a top cover 2 and two side plates 3, which are respectively mounted on both sides of the inner liner 100. The top of the side plates 3 is folded inward to form a mounting plate 31, on which a water droplet hole 32 is provided. The top cover 2 is provided with a locking block 21 for limiting the position of the water droplet hole 32. The length of the water droplet hole 32 is greater than the length of the locking block 21, allowing the locking block 21 to naturally extend into the water droplet hole 32. When installing the top cover 2, first insert the locking block 21 into the water droplet hole 32, then slide the top cover 2 horizontally, causing the locking block 21 to slide to the narrow section of the water droplet hole 32 to limit the position of the top cover 2. When removing the top cover 2, simply move the top cover 2 in the opposite direction to slide the locking block 21 to the wide section of the water droplet hole 32, and then remove the top cover 2.

[0035] Understandably, traditional top cover 2 is usually fixed to side plate 3 with bolts, which is relatively troublesome in terms of installation and disassembly; however, this application adopts a sliding limit method between the locking block 21 and the water drop hole 32, which can further improve the installation and disassembly speed of top cover 2.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, there are multiple water droplet holes 32 and multiple locking blocks 21. The multiple water droplet holes 32 are arranged along the long side of the mounting plate 31, and the multiple locking blocks 21 are arranged sequentially on the end face of the top cover 2. The limiting cooperation at multiple positions can improve the installation stability of the top cover 2 on the one hand, and effectively prevent the top cover 2 from warping on the other hand.

[0037] Furthermore, such as Figure 3 and Figure 5As shown, in order to further improve the limiting effect between the locking block 21 and the water droplet hole 32, the locking block 21 in this embodiment is L-shaped, and the locking block 21 cooperates with the end face of the top cover 2 to form a locking cavity. The width of the locking cavity shows a continuous decreasing trend from the outside to the inside. When the locking block 21 slides in the water droplet hole 32, the mounting plate 31 extends into the locking cavity and slides. When the mounting plate 31 reaches the narrow part of the locking cavity, the mounting plate 31 squeezes the locking block 21 and locks it in an interference fit, thereby simultaneously limiting the top cover 2 axially and radially, further improving the installation stability of the top cover 2.

[0038] It should be noted that when the top cover 2 is connected by an interference fit, if the user applies too much force when moving the top cover 2, the locking block 21 may become stuck with the water drop hole 32 due to excessive deformation, which will cause trouble for the subsequent disassembly of the top cover 2.

[0039] To address the above issues, in some embodiments of this application, a baffle 4 is also installed on the inner liner 100, and the baffle 4 is perpendicularly connected to the side panels 3 on both sides. A limiting groove 41 is provided on the baffle 4, and a limiting block 22 is provided on the top cover 2 to cooperate with the limiting groove 41. The limiting groove 41 and the limiting block 22 limit the top cover 2. When the top cover 2 is installed, the limiting block 22 extends into the limiting groove 41, further improving the limiting effect on the top cover 2 and preventing the top cover 2 from falling off when the dishwasher shakes.

[0040] Furthermore, such as Figure 4 and Figure 6 As shown, the side of the top cover 2 away from the limiting groove 41 is folded downward to form a baffle 23. After the top cover 2 is installed, the baffle 23 at the rear fits against the baffles 23 on both sides and limits the side plate 3, thereby preventing the side plate 3 from tilting. In addition, in order to further improve the stability of the side plate 3, a boss 11 is also provided on the base 1. The lower part of the two side plates 3 is connected to the boss 11, and the upper part of the two side plates 3 is connected by a connector 300. The connector 300 can cooperate with the boss 11 to limit the distance between the two side plates 3, so as to ensure that the position of the two side plates 3 does not change when the top cover 2 is moved.

[0041] It should be understood that dishwashers vibrate slightly during operation. Therefore, in existing technology, the inner tub 100 is mostly fixed to the base 1 by clips. However, the clips will inevitably be affected by repeated insertion and removal over a long period of time. If the inner tub 100 becomes loose between itself and the base 1, the inner tub 100 may shift from its original position due to the vibration of the dishwasher.

[0042] Therefore, in this embodiment, as Figure 6 and Figure 7As shown, a locking structure is provided between the boss 11 and the inner liner 100. This locking structure locks the position of the inner liner 100, thereby improving its installation stability. The locking structure includes a side lug 101 and a baffle 200. The side lug 101 is arranged along the side of the inner liner 100, and the baffle 200 is installed on the upper part of the boss 11, with an overlapping surface between the baffle 200 and the side lug 101. The inner liner 100 is locked by the limiting cooperation between the baffle 200 and the side lug 101. When the inner liner 100 is placed on the base 1, the upper end face of the boss 11 and the upper end face of the side lug 101 are on the same horizontal plane. Then, the baffle 200 is fixedly installed on the upper end face of the boss 11, ensuring that part of the baffle 200 is above the side lug 101, thus limiting the installation of the inner liner 100 on the base 1.

[0043] In this embodiment, as Figure 8 As shown, the dishwasher also includes a door 5, a locking rod assembly 6 installed on the inner tub 100, and a latch assembly 7 on the door 5. The locking rod assembly 6 is used to lock / unlock the door 5 in conjunction with the latch assembly 7. When the door 5 is closed, the locking rod assembly 6 and the latch assembly 7 lock the door 5 in place, preventing it from opening due to vibration during dishwasher operation.

[0044] Specifically, such as Figure 9 and Figure 10 As shown, the locking rod assembly 6 includes a housing 61 and a sliding rod 62. A sliding groove is provided inside the housing 61, and the sliding rod 62 is slidably mounted in the sliding groove. The sliding rod 62 is inclined downwards towards the latch assembly 7 to increase the gap when the door 5 is opened. The latch assembly 7 includes a bracket 71 and a hook 72. The bracket 71 is mounted on the door 5, and the hook 72 is rotatably mounted on the bracket 71. The sliding rod 62 has a lock hole 620 for engaging the hook 72. Additionally, an elastic element is provided between the hook 72 and the bracket 71 to limit the initial position of the hook 72, allowing it to rotate back to its initial position after the force on the hook 72 disappears. When the door 5 needs to be closed, the hook 72 engages the lock hole 620, and then the sliding rod 62 retracts into the housing 61, causing the door 5 to rotate in the closing direction. When the door 5 needs to be opened, the sliding rod 62 extends outwards from the housing 61, causing the door 5 to rotate in the opening direction. In addition, the downward tilt of the sliding rod 62 can increase the gap when the door 5 is opened, and also allow the sliding rod 62 to adapt to the height difference between the door 5 and the housing 61, thus extending the service life of the sliding rod 62.

[0045] In addition, to further improve the user experience, a drive module and a sensor module can be set on the latch assembly 7 and the locking rod assembly 6. The position information of the sliding rod 62 is transmitted to the drive module through the sensor module, and then the drive module controls the sliding rod 62 to slide in the desired direction to realize the automatic locking / unlocking of the door 5.

[0046] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
