Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a water tank installation structure and cooking equipment. Background Technology

[0002] With the continuous upgrading of consumer demand, steam cooking equipment is increasingly favored by families due to its unique cooking method and healthy concept. Existing cooking equipment usually has a water tank on top to supply water to the steam generator during operation; as steam is continuously consumed, users need to manually remove or automatically pop out the water tank to add water every once in a while.

[0003] To facilitate smoother water tank removal, either a beetle-shaped or magnetic rebound structure made of all-plastic materials is typically used. However, the all-plastic beetle-shaped rebound mechanism generally suffers from short lifespan and poor reliability; while the magnetic rebound structure requires magnets, which are prone to insufficient suction. Furthermore, if the water level in the tank is high, it can easily overflow during sliding, leading to rust on the magnetic components. To address this, Chinese Patent Application No. 202022837720.7 discloses a water tank structure and a cooking device using it, including a water tank body and a water tank support. The water tank body is housed within the water tank support. The device also includes a push-out component for pushing the water tank body and a controller. The push-out component is located on the water tank support, and the controller is located on the cooking device and connected to the push-out component, controlling the push-out component to push the water tank body. This solution has a simple overall structure and stable operation, but it suffers from the drawback of the water tank easily detaching from the support.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the structure of the spring-loaded device of the existing water tank is unreasonable, which makes the water tank easy to accidentally fall out of the mounting base and affect the operational stability.

[0006] To address the aforementioned problems, this utility model provides a water tank installation structure, including a water tank, a mounting base, and a water receiving plate. The mounting base is fixedly mounted on the water receiving plate, and one end of the mounting base has an opening. An elastic component is provided at the end of the mounting base away from the opening to cushion the water tank when pushed in or pulled out through the opening. A locking component is provided on the water receiving plate, including an elephant trunk lock. A U-shaped groove is provided on the rear side wall of the water tank, and the elephant trunk lock can selectively limit and lock the U-shaped groove. This design utilizes the elastic component to provide precise pressing and ejection force to ensure a good pressing feel, while the elephant trunk lock limits the installation of the water tank to prevent it from accidentally sliding out of the mounting base, resulting in a superior user experience.

[0007] Preferably, the water-receiving plate has a mounting position at the end away from the opening for limiting the assembly of the elephant trunk lock; a pressure block is provided on the mounting base, the pressure block being located above the mounting position for pressing the elephant trunk lock. This arrangement ensures that the elephant trunk lock is not easily dislodged from the mounting position, resulting in a simple structure and high installation efficiency.

[0008] Preferably, the elephant trunk lock has a movable block on the side near the water tank, and a pivot is provided at the free end of the movable block. This arrangement allows the elephant trunk lock to roll into contact with the U-shaped groove, reducing running resistance and ensuring smoother pressing.

[0009] Preferably, the locking assembly further includes a micro switch and a rotating swing arm. A fixing post and a buckle are provided on the water receiving plate. The rotating swing arm is rotatably fitted onto the fixing post. The buckle is adjacent to the fixing post and is used to limit the rotation of the swing arm in the vertical direction. The micro switch is adjacent to the rotating swing arm. When the water tank is pushed in, it can push one end of the rotating swing arm to rotate and trigger the micro switch. This design allows for precise detection of the water tank being pushed into the mounting base, preventing leakage at the inlet and outlet pipe joints due to the water tank not being properly installed.

[0010] Preferably, the elastic component includes a push rod, a bushing, and a spring. The bushing is fixed to the rear side wall of the mounting base, and the spring is disposed inside the bushing. The push rod is provided with a limiting rib for limiting the spring. One end of the push rod passes through the spring and is inserted into the bushing. The push rod has a disc-shaped contact block at one end near the water tank for contacting the water tank when it is pushed in or out and providing a buffering force.

[0011] This design ensures that the water tank provides a cushioning force during the final push-in stage and an elastic force during the initial push-out stage, resulting in a smoother operation. In addition, the water tank is relatively long, and the frictional resistance of the push-button is greater after being filled with water. The elastic component can provide additional thrust to ensure that the water tank panel remains flush with the glass panel. At the same time, by adjusting the spring force, the push-button feel can be precisely controlled. The push-button stroke remains unchanged during high-frequency operation, the spring compression stroke is precise, and the push-button feel is without deviation.

[0012] Preferably, the bushing includes a hollow, interconnected first end and a second end. The inner diameter of the first end is smaller than the inner diameter of the second end. The end of the push rod furthest from the contact block is inserted into the first end. The second end is used to accommodate the spring. A fixing wing is provided on the outer wall of the second end for fixed connection with the mounting base. This design is simple and easy to manufacture.

[0013] Preferably, the water receiving plate has an assembly hole at the end away from the opening. The mounting base is connected to the water receiving plate by screws. The mounting base has a slotted hole, and the free end of the screw passes through the slotted hole and is threaded into the assembly hole, pressing the mounting base from both sides to limit its position. This design allows for manual adjustment even when there are dimensional deviations in the parts, and enables the mounting base to be positioned and fixed in the front-to-back direction, ensuring that the exterior surface of the water tank remains flush with other components after installation, thus ensuring the aesthetic appearance of the product.

[0014] Preferably, a first limiting structure is provided between the two sides of the water tank and the mounting base to constrain the installation position of the water tank in the vertical direction; a slide rail is provided at the bottom of the water tank to abut against the mounting base, and a guide groove is provided on the inner side wall of the mounting base to constrain the position of the slide rail in the horizontal direction.

[0015] This design allows for precise positioning of the water tank within the mounting base, ensuring uniform left and right clearances and contributing to an aesthetically pleasing overall appearance. Simultaneously, the limited contact area between the slide rail and the mounting base minimizes frictional resistance and prevents noticeable scratches on the bottom of the water tank. This also improves the feel of pushing the water tank in and out, resulting in a superior user experience.

[0016] Compared with the prior art, the water tank installation structure of this utility model has the following beneficial effects: 1) By cooperating with the elephant trunk lock and the elastic component, it can not only ensure the pressing feel when pressing in and pushing out, but also limit the water tank after installation to prevent it from accidentally sliding out of the mounting base; 2) The elephant trunk lock and the U-shaped groove make rolling contact, making the pressing and pushing operation smoother; 3) The elastic component can provide additional thrust after the water tank is pushed in, ensuring that the water tank panel is flush with the panel glass and has an aesthetically pleasing appearance; 4) By setting a micro switch, the installation position of the water tank can be accurately detected, effectively preventing water leakage at the joint due to the water tank not being installed in place.

[0017] This utility model also provides a cooking device, which includes a cooking cavity. A steam generator and the aforementioned water tank mounting structure are disposed on the top of the cooking cavity. The mounting bracket of the water tank mounting structure is located on the front top side of the cooking cavity, and the water inlet assembly of the water tank is connected to the steam generator. The cooking structure has the same beneficial effects as the water tank mounting structure, and will not be described in detail here. Attached Figure Description

Detailed Implementation

[0033] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of this utility model can be combined with each other.

[0034] Cooking equipment with steaming function (such as steam ovens, steam ovens, etc.) is equipped with a water tank assembly. In the case of a top-mounted water tank assembly, the water tank base has an opening at the front, allowing the water tank 1 to extend through the opening for water filling. Because both the water tank 1 and the water tank base are relatively long, they are prone to deformation. Furthermore, any assembly misalignment can cause the water tank panel 13 to become misaligned with the panel glass 41 after installation, affecting the appearance. Therefore, the applicant proposes the following technical solution:

[0035] Example 1

[0036] like Figure 1-8 As shown, a water tank installation structure includes a water tank 1 and a mounting base 2. One end of the mounting base 2 has an opening, through which the water tank 1 can be pushed into and pulled out of the mounting base 2. A first limiting structure is provided between the two sides of the water tank 1 and the mounting base 2 to constrain the installation position of the water tank 1 in the vertical direction. A slide rail rib 113 is provided at the bottom of the water tank 1, and the slide rail rib 113 extends along the length direction of the water tank 1. A guide groove 23 is provided on the inner side wall of the mounting base 2 to constrain the position of the slide rail rib 113 in the horizontal direction.

[0037] This setting can precisely limit the position of water tank 1 within the mounting base 2 to ensure uniform left and right gaps, which is beneficial to the overall aesthetic appearance; at the same time, the contact area between the slide rail rib 113 and the mounting base 2 is limited, resulting in low frictional resistance and avoiding obvious scratches on the bottom surface of water tank 1; it improves the feel of pushing in and popping out water tank 1, providing a better user experience.

[0038] As an example of this utility model, the first limiting structure includes a guide rib 112 and a guide groove 22. The guide groove 22 is located on one of the water tank 1 and the mounting base 2, and the guide rib 112 is located on the other of the water tank 1 and the mounting base 2. The guide groove 22 is located on the side near the opening and is flared. The guide rib 112 is arrow-shaped and can be limited and assembled into the guide groove 22. This setting has low requirements for the initial position of the water tank 1 and does not require the user to perform alignment operations during installation, but it can ensure that the final position of the water tank 1 in the mounting base 2 is accurate and ensure the installation accuracy of the water tank 1 in the vertical direction. At the same time, the contact distance between the guide rib 112 and the guide groove 22 is short, and the resistance when the water tank 1 is pushed in and pulled out is small.

[0039] As an example of this utility model, the slide rail rib 113 is located at the end of the water tank 1 near the opening and extends along the length of the water tank 1; two slide rail ribs 113 are spaced apart and abut against one of the two side walls of the guide groove 23 respectively, and the two slide rail ribs 113 gradually tilt and move closer to each other at the end away from the opening. This arrangement uses two slide rail ribs 113 to achieve stable support for the water tank 1 to ensure that it is in a horizontal state; at the same time, the gradual inward contraction and convergence of one end of the two slide rail ribs 113 can also play a guiding role to ensure that no alignment operation is required by the user during installation, and finally, in conjunction with the limiting structure, it achieves precise positioning of the water tank 1 in the vertical plane.

[0040] Preferably, the slide rail rib 113 and the mounting base 2 have point contact. This arrangement reduces the contact area between the water tank 1 and the mounting base 2, ensuring the final installation position accuracy. It also helps to distribute the force on the water tank 1 in conjunction with the guide rib 112, preventing excessive local stress. For example, the two ends of the slide rail rib 113 gradually increase in height, thus creating two or more points of contact between the slide rail rib 113 and the mounting base 2.

[0041] Preferably, the water tank mounting structure further includes a water receiving plate 3, and the mounting base 2 is detachably assembled onto the water receiving plate 3. The water receiving plate 3 is provided with an assembly hole 31, and the mounting base 2 is provided with a waist-shaped hole 24 at a position corresponding to the assembly hole 31. The free end of the screw 25 passes through the waist-shaped hole 24 and is threadedly connected to the assembly hole 31, and squeezes the mounting base 2 from both sides to limit its position.

[0042] Each part of the water tank installation structure has a certain tolerance. By setting the waist-shaped hole 24 as an adjustable structure, even if the part has a dimensional deviation, it can be manually adjusted and the mounting base 2 can be positioned and fixed in the front and rear directions. This ensures that the appearance of the water tank 1 is flush with other parts after installation, resulting in a high aesthetic appearance.

[0043] As an example of this utility model, the water tank 1 includes a tank body 11 and a cover plate 12. The cover plate 12 covers the tank body 11 and has annular ribs 122 on its outer periphery. An annular sealing ring 15 is provided on one side of the annular ribs 122. The sealing ring 15 abuts against the inner wall of the tank body 11. The inner wall of the tank body 11 has multiple protrusions 114 at the same height, which are used to limit the annular ribs 122.

[0044] Because the cover plate 12 is relatively long, it is prone to bending, deformation, and warping after injection molding. The protrusion 114 limits the annular rib 122 to prevent warping, ensuring good sealing performance and product aesthetics of the water tank 1; at the same time, it increases the mechanical strength of the cover plate 12. The connection and assembly between the tank body 11 and the cover plate 12 is prior art and will not be described in detail here.

[0045] The cover plate 12 is provided with a water inlet, and a cap 121 is provided at the water inlet. The cap 121 is hinged to the cover plate 12 and can selectively block the water inlet. Its specific structure is prior art and will not be described in detail here.

[0046] Preferably, the water tank 1 is provided with a water inlet assembly 14, which includes a water inlet pipe 141 and a filter screen 142. The free end of the water inlet pipe 141 is configured as a tower structure, and the middle cross-sectional area of ​​the tower structure is larger than the cross-sectional areas of both ends, which is used to limit the assembly of the filter screen 142. The lower end of the tower structure is provided with a protrusion 1411.

[0047] This design ensures that the filter screen 142 is securely and reliably installed within the water inlet pipe 141. Simultaneously, the protrusions 1411 ensure a certain gap at the water inlet, preventing blockage of the water path. Preferably, the water inlet pipe 141 is positioned close to the same height as the water tank 1, which reduces the length of the water inlet connector 115, prevents sticking to the mold, facilitates the ejection of injection molded parts, and improves mold reliability. The structure is simple and production is easy.

[0048] Preferably, a water inlet connector 115 is provided at the upper part of the water tank 1, and one end of the water inlet pipe 141 is inserted and assembled with the water inlet connector 115. This arrangement effectively reduces the mold height to prevent sticking during demolding, resulting in low production costs.

[0049] Preferably, steps 111 are provided at the middle positions of both sides of the tank body 11, with one end of the steps 111 gradually sloping downwards and extending to the bottom of the tank body 11. This arrangement makes the steps 111 encircle and resemble a locomotive, greatly enhancing the mechanical strength of the left and right side walls of the tank body 11, effectively preventing the tank body 11 from deforming inwards, and ensuring the overall aesthetic appearance of the water tank 1. If reinforcing ribs are provided inside the tank body 11, it will not increase the complexity of the mold and effectively avoid the problem of sticking during demolding, but it will also increase the difficulty of cleaning the tank body 11 itself.

[0050] The water tank mounting structure also includes a mounting bracket 4, which has a notch, through which the water tank 1 is pushed in or pulled out. The mounting bracket 4 has a folded edge 42, and a bending plate 43 is provided on the folded edge 42. The mounting base 2 has a limiting hole 26 at one end near the opening. The bending plate 43 passes through the limiting hole 26 and is bent to achieve the limiting and fixing of the mounting bracket 4 and the mounting base 2.

[0051] The structure is simple. The buckle can be locked by bending the bending plate 43 at an angle. The locking force is strong and it is not easy to loosen. The whole process does not require the use of screws for fixing, and the assembly is convenient and reliable.

[0052] Preferably, the mounting base 2 is provided with a plurality of limiting blocks 21 on the outer periphery of the opening, and the limiting blocks 21 abut against the mounting frame 4. This arrangement can overcome the unstable assembly position caused by the poor mechanical strength of the folded edge 42, and achieve precise positioning of the mounting base 2 by cooperating with the bending plate 43. The whole process is simple and reliable.

[0053] Preferably, a water tank panel 13 is provided at one end of the water tank 1, and a panel glass 41 is provided on the outside of the mounting bracket 4. The water tank panel 13 can be embedded in the panel glass 41 after the water tank 1 is installed.

[0054] Example 2

[0055] When the installation position of water tank 1 within mounting base 2 changes, not only does water tank 1 protrude from panel glass 41, affecting aesthetics, but it also leads to poor connection between water tank 1 and steam generator, potentially causing a failure to supply water. Therefore, based on embodiment 1, the applicant proposes the following technical solution:

[0056] like Figure 9-13As shown, a water tank installation structure includes a water tank 1, a mounting base 2, and a water receiving plate 3. The mounting base 2 is fixedly mounted on the water receiving plate 3. One end of the mounting base 2 has an opening, and an elastic component 5 is provided at the end of the mounting base 2 away from the opening to buffer the water tank 1 when it is pushed in or pulled out through the opening. A locking component 6 is provided on the water receiving plate 3. The locking component 6 includes an elephant trunk lock 61. A U-shaped groove 116 is provided on the rear side wall of the water tank 1. The elephant trunk lock 61 can selectively limit and lock the U-shaped groove 116.

[0057] This setup utilizes the elastic component 5 to provide precise pressing and ejection force to ensure a good pressing feel, while the elephant trunk lock 61 limits the installation of the water tank 1 to prevent it from accidentally sliding out of the mounting base 2, resulting in a superior user experience. The structure of the elephant trunk lock 61 is existing technology and will not be described in detail here.

[0058] As an example of this utility model, the water receiving plate 3 has a mounting position 32 at the end away from the opening for limiting the assembly of the elephant trunk lock 61; the mounting base 2 has a pressure block 27, which is located above the mounting position 32 for pressing the elephant trunk lock 61; the elephant trunk lock 61 has a movable block 611 on the side near the water tank 1, and a rotating shaft 612 is provided at the free end of the movable block 611. This arrangement ensures that the elephant trunk lock 61 is not easily dislodged from the mounting position 32, has a simple structure and high installation efficiency; at the same time, the rotating shaft 612 makes rolling contact with the U-shaped groove 116, ensuring smoother pressing.

[0059] Preferably, the locking assembly 6 further includes a micro switch 62 and a rotating arm 63. The water receiving plate 3 is provided with a fixing post 33 and a buckle 34. The rotating arm 63 is rotatably sleeved on the fixing post 33. The buckle 34 is arranged adjacent to the fixing post 33 and is used to limit the rotating arm 63 in the vertical direction. The micro switch 62 is arranged adjacent to the rotating arm 63 and can push one end of the rotating arm 63 to rotate and trigger the micro switch 62 to perform an action when the water tank 1 is pushed in.

[0060] This setup enables precise detection of the water tank 1 being pushed into the mounting base 2, preventing leaks at the inlet and outlet pipe joints due to the water tank 1 not being properly installed. The micro switch 62 is mounted on the water receiving plate 3 using methods such as snap-fit ​​or screw connection.

[0061] As an example of this utility model, the elastic component 5 includes a push rod 51, a bushing 52, and a spring 53. The bushing 52 is fixed to the rear side wall of the mounting base 2. The spring 53 is disposed inside the bushing 52. One end of the push rod 51 passes through the spring 53 and is inserted into the bushing 52. A limiting rib 512 is provided on the push rod 51 to limit the spring 53. A disc-shaped contact block 511 is provided at one end of the push rod 51 near the water tank 1 to contact the water tank 1 and provide a buffering force when the water tank 1 is pushed in or out.

[0062] This setup ensures that the water tank 1 provides a buffering force during the final stage of pushing in and an elastic force during the initial stage of pushing out, thus making the entire operation smoother. In addition, the water tank 1 is relatively long, and the frictional resistance of the push button is large after being filled with water. The elastic component 5 can provide additional thrust to ensure that the water tank panel 13 and the panel glass 41 remain flush. At the same time, by adjusting the elasticity of the spring 53, the push button feel can be precisely controlled. The push button stroke remains unchanged during high-frequency operation, the spring 53 is compressed precisely, and the push button feel is without deviation.

[0063] Preferably, the bushing 52 includes a hollow, interconnected first end 521 and a second end 522. The inner diameter of the first end 521 is smaller than the inner diameter of the second end 522. The push rod 51 is inserted into the first end 521. The second end 522 is used to accommodate the spring 53. A fixing wing 523 is provided on the outer wall of the second end 522 for fixed connection with the mounting base 2. This design is simple and easy to manufacture.

[0064] When water needs to be added, press the water tank 1 to move it inward and trigger the micro switch 62 by rotating the swing arm 63, thereby unlocking the elephant trunk lock 61. The water tank 1 pops outward under the action of the elastic component 5. After water is added, press the water tank 1 to move it inward. The movable block 611 of the elephant trunk lock 61 rolls into the U-shaped groove 116 through the rotating shaft 612. By rotating the swing arm 63 to trigger the micro switch 62, the elephant trunk lock 61 locks the water tank 1. Then, the water tank 1 moves in the opposite direction under the action of the elastic component 5, so that the elephant trunk lock 61 locks the water tank 1. At this time, the water tank 1 bears the thrust of the elastic component 5, ensuring that the water tank panel 13 is flush with the panel glass 41.

[0065] This utility model also provides a cooking device, which includes a cooking cavity. A water tank mounting structure and a steam generator are disposed on the top of the cooking cavity. The mounting bracket 4 is located on the front top side of the cooking cavity. The water inlet assembly 14 of the water tank 1 is connected to the steam generator. The cooking structure also includes a door assembly, a fan, and other components, the specific structure and assembly relationship of which are existing technologies.

[0066] While the present invention has been disclosed above, it is not limited thereto.
