[0002] A drying sink is an important kitchen appliance. After washing dishes, they are dried in the drying chamber of the drying sink, thus preventing bacteria from easily growing due to the damp environment.

[0003] Typically, a drying tank includes a tank body, a drying chamber installed inside the tank body, and an air inlet box located on one side of the washing tank in the tank body. The air inlet box is equipped with an air inlet and an air outlet. The air outlet is connected to the drying chamber through an air duct. A heating component is installed along the air duct path to heat the air entering the air duct from the air inlet. The heated hot air is then sent into the drying chamber to dry the tableware.

[0004] Since the air inlet box is located on one side of the cleaning tank, it is designed as a split structure for easy maintenance. In the existing technology, a sealing ring structure is usually set between the split structures of the air inlet box, but the sealing effect is not good. When using the cleaning tank for cleaning operations, water often enters the air inlet box. Moreover, there is also a risk of water entering between the air inlet box and the tank, which shortens the service life. Utility Model Content

[0005] The purpose of this utility model is to propose an air inlet box and a drying water tank, which solves the technical problem that the air inlet box is prone to water ingress and has a shortened service life in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides an air inlet box body, which is installed on the tank of a drying water tank. The air inlet box body includes a bottom shell and a top cover.

[0010] The top cover is equipped with a snap-fit ​​support, which snaps into the waterproof edge, thus achieving the snap-fit ​​connection between the top cover and the bottom shell. This snap-fit ​​connection not only serves to position the top cover during installation but also enhances the support strength of the top cover.

[0011] As a preferred embodiment of the aforementioned air inlet box, the side wall of the snap-fit ​​support facing the top cover is a first side wall, and the top of the snap-fit ​​support and / or the first side wall is connected to the inner wall of the top cover.

[0012] The top and / or first sidewall of the snap-fit ​​support are connected to the inner wall of the top cover, thereby enabling the snap-fit ​​support to be installed and fixed.

[0013] As a preferred embodiment of the above-mentioned air inlet box, a snap-fit ​​groove is provided at the bottom end of the first side wall, the snap-fit ​​groove passing through the end face of the bottom end of the snap-fit ​​support, and the waterproof baffle can be snapped into the snap-fit ​​groove.

[0014] When the top cover is installed on the bottom shell from top to bottom, the snap-fit ​​groove allows the waterproof edge to extend into the snap-fit ​​groove as the top cover moves downward. The design of the snap-fit ​​groove makes it easier to assemble the top cover and the bottom shell.

[0015] As a preferred embodiment of the above-mentioned air inlet box, the side wall of the snap-fit ​​support member opposite to the first side wall is the second side wall, and the groove wall of the snap-fit ​​groove opposite to the side wall of the top cover is inclined from top to bottom toward the direction close to the second side wall.

[0016] The above-mentioned design allows the waterproof edge to abut against the groove wall of the snap-fit ​​groove, which is opposite to the side wall of the top cover, thereby achieving the snap-fit ​​function.

[0017] As a preferred embodiment of the aforementioned air inlet box, the top cover is provided with a plurality of snap-fit ​​support members spaced apart along its circumference.

[0018] The top cover is well supported by multiple snap-fit ​​support components in conjunction with the waterproof edge.

[0019] As a preferred embodiment of the aforementioned air inlet box, the top cover is fastened onto the groove, the side wall of the top cover abuts against the groove, and the top cover and the groove form an accommodating space. The bottom shell is disposed within the accommodating space, and the abutment position of the side wall of the top cover against the groove is lower than the top surface of the waterproof edge.

[0020] The top cover is fastened onto the tank body. The contact point between the side wall of the top cover and the tank body is lower than the top surface of the water-blocking edge, so that the contact point between the side wall of the top cover and the tank body is offset from the top surface of the waterproof edge, thereby achieving a better waterproof effect.

[0021] As a preferred embodiment of the above-mentioned air inlet box, the bottom shell and the groove are sealed and bonded together with sealant.

[0022] The bottom shell and the tank are sealed and bonded together with sealant, which not only fixes the bottom shell together, but also seals the bottom shell and the tank together, effectively providing waterproofing.

[0023] As a preferred embodiment of the aforementioned air inlet box, the bottom shell, the top cover, and the groove are connected by fasteners.

[0024] The bottom shell, top cover, and tank are connected by fasteners, making it easy to assemble and disassemble the top cover.

[0025] This utility model also provides a drying water tank, including the aforementioned air inlet box.

[0026] The drying tank achieves good waterproofing through the aforementioned air inlet box, extending its service life.

[0027] The beneficial effects of this utility model are:

[0028] The air inlet box proposed in this utility model includes a bottom shell and a top cover. The bottom shell is sealed to the tank to prevent water from entering between the bottom shell and the tank. The top cover is placed on the bottom shell and is detachably connected to the bottom shell, which facilitates maintenance by removing the top cover.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] like Figures 1-4 As shown, this embodiment provides a drying tank, which includes a tank body 100 and a drying chamber 300 installed on the tank body 100. A cleaning tank 101 is provided on the tank body 100 for cleaning operations and can also accommodate the drying chamber 300. An air inlet box 400 is provided on one side of the tank body 100 near the cleaning tank 101. The air inlet box 400 is provided with an air inlet 4221 and an air outlet 412 (see...). Figure 2 The air outlet 412 is connected to the heating element (not shown in the figure) via the air inlet channel 200, and the heating element is connected to the drying chamber 300 via the air outlet duct. The heating element includes at least a fan and heating components. The fan powers the airflow, and the heating components heat the air for drying the tableware. The specific connections and installation positions of the various structures of the heating element are prior art and will not be described further here.

[0048] When drying tableware, air is introduced into the heating element through the air inlet 4221 and the air inlet channel 200 for heating. The hot air heated by the heating element is then sent into the drying chamber 300 to dry the tableware.

[0049] Furthermore, the air inlet box 400 is installed on the tank body 100 of the drying water tank and located on one side of the washing tank 101. For ease of maintenance, the air inlet box 400 includes a separate bottom shell 41 and a top cover 42. The top cover 42 covers the bottom shell 41 and is detachably connected to the bottom shell 41, so that its internal structure can be repaired by removing the top cover 42. Since the air inlet box 400 is located on one side of the washing tank 101, the separate structure of the air inlet box 400 often leads to water ingress when using the washing tank 101 for cleaning operations. This water ingress includes water entering the air inlet box 400 through the air outlet 412 through the gap between the bottom shell 41 and the tank body 100, and water entering through the gap between the bottom shell 41 and the top cover 42. Water ingress into the air inlet box 400 shortens the service life of the air inlet box 400 and the entire drying water tank.

[0050] To address the aforementioned issues, this embodiment proposes an air inlet box 400. The air inlet box 400 is installed on the tank body 100 of the drying water tank and located on one side of the washing tank 101. The air inlet box 400 includes a bottom shell 41 and a top cover 42. The bottom shell 41 is sealed to the tank body 100. The top cover 42 is placed on the bottom shell 41 and is detachably connected to the bottom shell 41. A waterproof baffle 411 is circumferentially protruding from the bottom shell 41. The top cover 42 is placed on the bottom shell 41, and the waterproof baffle 411 can extend into the top cover 42.

[0051] The bottom shell 41 of the air inlet box 400 has a circumferentially protruding waterproof baffle 411. When the top cover 42 is placed on the bottom shell 41, the waterproof baffle 411 can extend into the top cover 42, preventing water from entering between the bottom shell 41 and the top cover 42. The air inlet box 400 provides good waterproofing from all directions. The drying sink, through the aforementioned air inlet box 400, achieves good waterproofing, preventing the growth of bacteria and mold, and facilitating a healthy kitchen.

[0052] In this embodiment, a waterproof flange 411 is provided along the entire circumferential edge of the bottom shell 41 to provide waterproofing for both the bottom shell 41 and the top cover 42. The waterproof flange 411 is formed by flanging the edge of the bottom shell 41. The waterproof flange 411 and the bottom shell 41 are an integral structure, reducing the number of assembly steps. Moreover, the integral structure of the bottom shell 41 has no installation gaps, resulting in better waterproofing.

[0053] like Figure 2As shown, the top cover 42 includes a cover plate 421 and side plates 422 disposed around the cover plate 421. When the top cover 42 is placed on the bottom shell 41, the top cover 42 is fastened to the groove 100. The side wall (side plate 422) of the top cover 42 abuts against the groove 100, and the top cover 42 and the groove 100 form an accommodating space. The bottom shell 41 is disposed within the accommodating space, that is, the top cover 42 can cover the entire bottom shell 41. The abutting position of the side wall (side plate 422) of the top cover 42 against the groove 100 is lower than the top surface of the waterproof edge 411, so that the abutting position of the side wall (side plate 422) of the top cover 42 against the groove 100 is misaligned with the top surface of the waterproof edge 411, thereby achieving a better waterproof effect. Even if water enters the gap from the contact point between the top cover 42 and the tank 100, the water is blocked by the waterproof baffle 411 because the top surface of the waterproof baffle 411 is high, and cannot enter the air inlet box 400.

[0054] In this embodiment, an air inlet 4221 is provided on the side plate 422 located on the rear side of the top cover 42 (the side plate 422 on the side away from the operator when using the drying water tank). Air enters into the air inlet box 400 through the air inlet 4221. An air outlet 412 is provided on the bottom shell 41. The air outlet 412 is connected to the inlet of the air inlet channel 200. The air inlet channel 200 is connected to the heating component. The heating component is connected to the drying chamber 300 through the air outlet channel.

[0055] Since the air inlet box 400 is set on the trough 100, a ventilation port is set on the trough 100 at the position of the air outlet 412 of the air inlet box 400, and the air outlet 412 is connected to the air inlet channel 200 through the ventilation port.

[0056] When drying tableware, air enters the air inlet box 400 through the air inlet 4221 and enters the air inlet channel 200 through the air outlet 412; the hot air heated by the heating element is sent into the drying chamber 300 through the air outlet channel to dry the tableware inside.

[0057] In this embodiment, multiple air inlets 4221 are provided and arranged in an array. The multiple air inlets 4221 increase the air intake area. The array arrangement of the air inlets 4221 not only improves the appearance but also prevents larger impurity particles from entering the air intake box 400 through the air inlets 4221. In other embodiments, the multiple air inlets 4221 are not limited to an array arrangement and can adopt other arrangements. Of course, the air inlet 4221 can also be designed as a large opening, such as a long strip or a circular hole, etc., without specific limitations.

[0058] In this embodiment, the bottom shell 41 and the tank 100 are sealed and bonded together with sealant, which not only bonds and fixes the bottom shell 41, but also achieves a seal between the bottom shell 41 and the tank 100, effectively providing a waterproof function.

[0059] like Figures 4-6 As shown, a snap-fit ​​support 43 is provided inside the top cover 42. The snap-fit ​​support 43 is snapped into the waterproof edge 411, thereby realizing the snap-fit ​​between the top cover 42 and the bottom shell 41. The snap-fit ​​support 43 and the waterproof edge 411 not only play a role in positioning the top cover 42 during installation, but also enhance the support strength of the top cover 42.

[0060] Specifically, such as Figure 6 As shown, the snap-fit ​​support 43 is a plate-shaped structure. One side of the snap-fit ​​support 43 faces and is close to the side wall of the top cover 42, and the other side faces the internal space of the top cover 42. The side wall of the snap-fit ​​support 43 facing the top cover 42 is the first side wall 431, and the side wall of the snap-fit ​​support 43 opposite to the first side wall 431 is the second side wall 432. The top of the snap-fit ​​support 43 and / or the first side wall 431 are connected to the inner wall of the top cover 42, thereby realizing the installation and fixation of the snap-fit ​​support 43.

[0061] In this embodiment, the top of the snap-fit ​​support 43 is adapted to the shape of the top surface of the top cover 42, the top of the snap-fit ​​support 43 is in contact with and connected to the top surface of the top cover 42, and the first side wall 431 is connected to the inner side of the side plate 422, which increases the connection area between the snap-fit ​​support 43 and the top cover 42, and realizes a firm connection between the snap-fit ​​support 43 and the top cover 42.

[0062] Furthermore, a snap-fit ​​groove 4311 is provided at the bottom end of the first sidewall 431. The snap-fit ​​groove 4311 passes through the end face of the bottom end of the snap-fit ​​support member 43, and the waterproof baffle 411 can snap into the snap-fit ​​groove 4311. When the top cover 42 is installed on the bottom shell 41 from top to bottom, the snap-fit ​​groove 4311 can be fitted onto the waterproof baffle 411 as the top cover 42 moves downward, so that the waterproof baffle 411 extends into the snap-fit ​​groove 4311. The design of the snap-fit ​​groove 4311 makes the assembly of the top cover 42 and the bottom shell 41 more convenient.

[0063] like Figure 5 and Figure 6 As shown, the groove wall of the snap-fit ​​groove 4311, which is opposite to the side wall of the top cover 42, slopes downwards towards the second side wall 432. This arrangement allows the waterproof edge 411 and the groove wall of the snap-fit ​​groove 4311, which is opposite to the side wall of the top cover 42, to gradually abut against each other during assembly, and the abutment force gradually increases, thereby achieving a better snap-fit ​​effect.

[0064] Preferably, a plurality of snap-fit ​​support members 43 are provided at intervals along the circumference inside the top cover 42. The multiple snap-fit ​​support members 43 cooperate with the waterproof edge 411 to achieve good support for the top cover 42. The specific number of snap-fit ​​support members 43 and the distance between adjacent snap-fit ​​support members 43 can be designed according to requirements and are not specifically limited here.

[0065] Optionally, the bottom shell 41, the top cover 42, and the groove 100 are connected by fasteners, making it easier to disassemble and assemble the top cover 42.

[0066] In this embodiment, as Figure 6 As shown, a stud 423 is provided inside the top cover 42. One end of the stud 423 is connected to the cover plate 421 of the top cover 42, and the other end of the stud 423 is provided with a threaded hole, such as... Figure 2 As shown, the bottom shell 41 is provided with a first mounting hole 413, and the groove 100 is provided with a corresponding second mounting hole 1011. During installation, the bottom shell 41 is sealed and bonded to the groove 100, and the first mounting hole 413 and the second mounting hole 1011 are positioned opposite each other; then, the top cover 42 is placed on the bottom shell 41, and the studs 423 on the top cover 42 extend into the first mounting hole 413 and the second mounting hole 1011, and are then connected to the threaded hole by screws, thereby connecting the top cover 42, the bottom shell 41, and the groove 100.

[0067] In other embodiments, the detachable connection between the top cover 42 and the bottom shell 41 is not limited to the above method. As long as the detachable connection between the top cover 42 and the bottom shell 41 or the detachable connection between the top cover 42 and the groove 100 can be achieved (since the bottom shell 41 is installed on the groove 100, when the top cover 42 is installed on the groove 100, it can be considered that the top cover 42 and the bottom shell 41 are relatively fixed).

[0068] Optionally, an operation panel 44 is provided on the cover plate 421 of the top cover 42. The operation panel 44 is equipped with operation keys and a display screen. The operation keys are associated with the functions that the drying water tank can perform, such as power keys, drying option keys, etc. The specific operation keys set on the operation panel 44 are not specifically limited here, and can be set according to specific needs. The display screen can display working parameters, such as drying temperature, drying time, etc.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
