Description

Technical Field

[0001] This application relates to the field of cooking equipment, and in particular to a water tank and cooking equipment. Background Technology

[0002] Currently, in steam ovens with external water tanks, to ensure a seamless appearance, the gap between the water tank's mounting frame and its outer contour is typically controlled at around 1-1.5mm. However, due to factors such as assembly methods, water tank mounting fixtures and processes, user experience, and uncontrollable quality issues with the water tank holder's ejector mechanism, the water tank can easily become stuck and fail to eject after prolonged use. Because of the small gap between the water tank and the main unit, it's difficult for both users and technicians to easily remove the stuck water tank. Replacing the water tank or its mounting assembly requires disassembling the entire unit. Since the water tank holder is a retrofitted structure, removal is often hindered by the stuck water tank, necessitating the removal of the fixed water tank holder from the main unit, removing the water tank, and then replacing the damaged holder. This increases the complexity and time cost of repairs. Utility Model Content

[0003] Therefore, it is necessary to provide a water tank and cooking equipment that can simplify the water tank replacement operation and save labor time while ensuring the overall appearance.

[0004] This utility model first provides a water tank for cooking equipment, comprising:

[0005] The housing has an operating surface at one end, and the operating surface has a sliding groove; and...

[0006] A blocking member is slidably disposed in the groove along the depth direction of the groove, and has a closed state and an open state. The blocking member includes a blocking surface corresponding to the opening of the groove.

[0007] In the closed state, the shielding surface and the operating surface are flush; in the open state, the shielding member extends into the slide groove.

[0008] With this design, when the water tank is in normal use, the cover is in the closed state, and the cover surface is flush with the operating surface, ensuring the integrity of the water tank's appearance. When the water tank cannot be ejected, the user can apply pressure to the cover to make it slide along the depth of the slide groove to the open state. The opening of the slide groove forms a space for the user to exert force on the hand. The user can use this space to apply pulling force to the water tank and easily remove the stuck water tank from the cooking device without disassembling the entire machine or the water tank base.

[0009] In one embodiment, the water tank further includes a telescopic component that extends along the depth direction of the chute. One end of the telescopic component is connected to the end of the chute away from the opening, and the other end is connected to the shield and can move with the shield.

[0010] With this configuration, the telescopic component, which extends along the depth of the slide, provides a stable guide for the sliding of the shield; at the same time, the telescopic component connects the slide and the shield, preventing the shield from falling out of the slide.

[0011] In one embodiment, the telescopic component includes a reset member, the two ends of which are respectively connected to the end of the slide away from the opening and the blocking member. In the open state, the reset member can drive the blocking member to slide to the closed state.

[0012] With this design, when the user applies pressure to open the cover to remove the stuck water tank, there is no need to manually push the cover back to the closed position. The reset component can automatically drive the cover to slide to the closed position, improving ease of use.

[0013] In one embodiment, the reset member is a compression spring that can be compressed and applies a force to the blocking member to slide it toward the closed state.

[0014] With this design, the compression spring has low cost and good linearity, and the compression stroke is proportional to the elastic force. During the design process, the return force requirements of water tanks of different sizes can be quickly matched by adjusting the wire diameter and the number of coils.

[0015] In one embodiment, the number of telescopic components is at least two sets, and each set of telescopic components is arranged at intervals along the length direction of the shield.

[0016] With this configuration, at least two sets of telescopic components are arranged at intervals along the length of the shield, which can support and guide the shield from multiple positions, ensuring that the shield always slides smoothly along the depth of the groove.

[0017] In one embodiment, the end of the slide away from the opening is provided with a guide post, and the side of the shield facing the telescopic assembly is provided with a guide groove that can be inserted and engaged with the guide post.

[0018] This configuration, with the guide post and guide groove interlocking, provides an additional guiding structure for the sliding of the blocking component, restricts the movement trajectory of the blocking component, and ensures that the blocking component always slides along the depth direction of the groove.

[0019] In one embodiment, the housing includes a main body and a front panel disposed at one end of the main body, the operating surface is disposed at the end of the front panel away from the main body, and the slide includes a groove disposed in the main body and an opening disposed in the front panel, the cross-sectional area of ​​the opening being smaller than the cross-sectional area of ​​the groove.

[0020] With this design, the cross-sectional area of ​​the opening is smaller than the cross-sectional area of ​​the tank, allowing the inner wall of the front panel to provide a hand position for the user to pull out the water tank.

[0021] In one embodiment, the outer periphery of the shield is provided with a limiting member, which abuts against the inner wall of the front panel in the closed state.

[0022] With this configuration, the limiting component abuts against the inner wall of the front panel when closed, which can restrict the blocking component from sliding out of the slide groove and prevent the blocking component from protruding from the slide groove opening due to excessive elasticity of the reset component or other external forces.

[0023] In one embodiment, the water tank further includes a press-and-rebound structure disposed between the water tank and the outer shell.

[0024] With this setup, when the press-and-rebound mechanism is working properly, the user can pop the water tank out using the conventional pressing method; when the press-and-rebound mechanism fails and causes the water tank to become stuck and unable to pop out, the user can remove the water tank by pressing the blocking part and using the opening to exert force.

[0025] This application also provides a cooking device, including the water tank described above.

[0026] With this design, the cooking equipment, by adopting the aforementioned water tank, can effectively solve the problems of existing cooking equipment where external water tanks are stuck, difficult to remove, and cumbersome to replace. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0037] Currently, in steam ovens with external water tanks, to ensure a seamless appearance, the gap between the water tank's mounting frame and its outer contour is typically controlled at around 1-1.5mm. However, due to factors such as assembly methods, water tank mounting fixtures and processes, user experience, and uncontrollable quality issues with the water tank holder's ejector mechanism, the water tank can easily become stuck and fail to eject after prolonged use. Because of the small gap between the water tank and the main unit, it's difficult for both users and technicians to easily remove the stuck water tank. Replacing the water tank or its mounting assembly requires disassembling the entire unit. Since the water tank holder is a retrofitted structure, removal is often hindered by the stuck water tank, necessitating the removal of the fixed water tank holder from the main unit, removing the water tank, and then replacing the damaged holder. This increases the complexity and time cost of repairs.

[0038] Therefore, in order to solve the above problems, such as Figures 1 to 3 As shown, this application provides a water tank and cooking equipment that, while ensuring an overall aesthetic appearance, simplifies the water tank replacement process and saves labor time.

[0039] like Figure 3 As shown, the X-axis is the length direction of the blocking component 2.

[0040] like Figure 1 and Figure 2 As shown, this application provides a water tank for cooking equipment, including a tank body and a shield 2. One end of the tank body is provided with an operating surface 3, and the operating surface 3 is provided with a groove 31. The shield 2 is slidably disposed in the groove 31 along the depth direction of the groove 31, and has a closed state and an open state. The shield 2 includes a shielding surface 21 corresponding to the opening of the groove 31. In the closed state, the shielding surface 21 is flush with the operating surface 3, and in the open state, the shield 2 extends into the groove 31.

[0041] With this configuration, when the water tank is in normal use, the cover 2 is in the closed state, and the cover surface 21 is flush with the operating surface 3, ensuring the integrity of the water tank's appearance and meeting the design requirements for the overall appearance of an external water tank. This avoids damage to the overall appearance of the machine due to additional protruding structures. When the water tank becomes stuck and cannot be ejected due to a malfunction of the rebound device or other factors, the user or maintenance technician can apply pressure to the cover 2, causing it to slide along the depth direction of the slide groove 31 to the open state. At this time, the cover 2 extends into the slide groove 31, and the opening of the slide groove 31 forms a space for the user to exert force. The user can apply pulling force through this space to easily remove the stuck water tank from the cooking equipment without disassembling the entire machine or the water tank base, simplifying the water tank replacement operation and saving labor time.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the water tank further includes a telescopic component 1. The telescopic component 1 extends along the depth direction of the slide groove 31. One end of the telescopic component 1 is connected to the end of the slide groove 31 away from the opening, and the other end is connected to the blocking member 2 and can move with the blocking member 2. This configuration, where the telescopic component 1 extends along the depth direction of the slide groove 31, provides stable guidance for the sliding of the blocking member 2, preventing the blocking member 2 from deviating from the depth direction of the slide groove 31 during sliding. Simultaneously, the telescopic component 1 connects the slide groove 31 and the blocking member 2, limiting the sliding range of the blocking member 2 and preventing it from falling out of the slide groove 31. When the user applies pressure to the blocking member 2 to open it, the movement of the telescopic component 1 can subsequently assist in resetting the blocking member 2, eliminating the need for the user to manually adjust its position and further improving ease of use.

[0043] In another embodiment, the telescopic component 1 can be designed to deviate from the depth direction of the slide 31. For example, the axis of the telescopic component 1 is at a 15° angle to the bottom surface of the slide 31, and the blocking member 2 moves downward and backward simultaneously when pushed in. With this configuration, the oblique movement causes the blocking member 2 to automatically sink in the open state, providing more space for the hand above the opening.

[0044] like Figure 1 and Figure 2As shown, in one embodiment, the telescopic component 1 includes a reset member, with its two ends connected to the end of the slide groove 31 furthest from the opening and the blocking member 2, respectively. In the open state, the reset member can drive the blocking member 2 to slide to the closed state. With this configuration, when the user applies pressure to open the blocking member 2 to remove the stuck water tank, there is no need to manually push the blocking member 2 back to the closed state; the reset member can automatically drive the blocking member 2 to slide to the closed state, improving ease of use. The reset member connects the slide groove 31 and the blocking member 2, further limiting the sliding range of the blocking member 2 and preventing it from falling off the slide groove 31. While ensuring the overall appearance, ease of water tank removal, and sliding stability of the blocking member 2, the reset member achieves automatic reset of the blocking member 2, further optimizing the user experience.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the reset element is a compression spring, which can be compressed and applies a force to the blocking element 2, causing it to slide towards the closed state. This configuration results in a low-cost, highly linear spring with a compression stroke proportional to the spring force. During design, the reset force requirements of different sized water tanks can be quickly matched by adjusting the wire diameter and number of coils. In another embodiment, the reset element can be designed as an elastic pull rope, a reset spring and transmission rod, a magnet, a spring assembly, or other structures capable of achieving the reset motion.

[0046] In another embodiment, the telescopic component 1 can also be designed as a nested sleeve, a pneumatic damping rod, a parallel guide rail, a shape memory alloy spring, or other structures capable of telescopic movement.

[0047] like Figure 3 As shown, in one embodiment, the number of telescopic components 1 is at least two sets, with each set of telescopic components 1 arranged at intervals along the length direction of the shield 2. In the illustrated embodiment, two sets of telescopic components 1 are arranged at intervals along the length direction of the shield 2. This arrangement, with at least two sets of telescopic components 1 arranged at intervals along the length direction of the shield 2, can support and guide the shield 2 from multiple positions. Compared to a single set of telescopic components 1, it can reduce the tilting or swaying of the shield 2 during sliding, ensuring that the shield 2 always slides smoothly along the depth direction of the slide groove 31, ensuring that the shielding surface 21 is flush with the operating surface 3 when closed, and can accurately extend into the slide groove 31 when open. The arrangement of two sets of telescopic components 1 ensures the support and guidance effect without excessively increasing the structural complexity and cost of the water tank. While ensuring the overall appearance, ease of removal, automatic reset function, and sliding stability, it further improves the smoothness and reliability of the sliding of the shield 2. The number of telescopic components 1 can be two, three, four, or more sets.

[0048] In another embodiment, at least two sets of telescopic components 1 are arranged vertically along the width direction of the shield 2.

[0049] In another embodiment, when the size of the shield 2 is small or there are other structural interferences in the slide 31, the telescopic assembly 1 can also be set as a set as needed.

[0050] The length of each telescopic component 1 can be designed according to actual needs. For example, the length of the middle telescopic component 1 can be greater than that of the two side telescopic components 1, and the elastic coefficient of the reset component in the middle telescopic component 1 can be greater than that of the two side components. When the blocking component 2 slides, the three telescopic components 1 extend and retract synchronously, with the middle component providing the main reset force. With this configuration, the longer middle telescopic component 1 can provide the main support for the middle part of the blocking component 2, preventing the middle part from sinking due to insufficient force; the reset component with a larger elastic coefficient can provide a stronger reset force, ensuring that the blocking component 2 resets synchronously as a whole, avoiding tilting caused by excessively fast reset on both sides; the shorter side components assist in guidance and balance the overall force.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the end of the slide groove 31 away from the opening is provided with a guide post 11, and the side of the blocking member 2 facing the telescopic component 1 is provided with a guide groove 22 that can be inserted and engaged with the guide post 11. This arrangement provides an additional guiding structure for the sliding of the blocking member 2, working together with the telescopic component 1 to further restrict the movement trajectory of the blocking member 2, ensuring that the blocking member 2 always slides along the depth direction of the slide groove 31, avoiding lateral swaying or tilting. The insertion and engagement structure is simple and reliable, effectively improving the accuracy of the sliding of the blocking member 2, ensuring that the blocking surface 21 is flush with the operating surface 3 when closed, and accurately extends into the slide groove 31 when open. Simultaneously, the cooperation between the guide post 11 and the guide groove 22 also provides some support for the blocking member 2, enhancing its stability during sliding.

[0052] Specifically, the bottom wall of the guide groove 22 is provided with a fixed post 221, and the two ends of the compression spring are respectively sleeved on the fixed post 221 and the guide post 11. The fixed post 221 and the guide post 11 provide mounting surfaces for the compression spring and limit the radial displacement of the compression spring.

[0053] In one embodiment, the end of the slide 31 away from the opening is provided with a guide groove 22, and the side of the shield 2 facing the telescopic assembly 1 is provided with a guide post 11 that can be inserted and engaged with the guide groove 22.

[0054] like Figure 1 and Figure 2As shown, in one embodiment, the housing includes a main body 4 and a front panel 311 disposed at one end of the main body 4. The operating surface 3 is disposed at the end of the front panel 311 away from the main body 4. The slide 31 includes a groove disposed in the main body 4 and an opening disposed in the front panel 311. The cross-sectional area of ​​the opening is smaller than the cross-sectional area of ​​the groove. This arrangement, where the cross-sectional area of ​​the opening is smaller than that of the groove, allows the inner wall of the front panel 311 to provide a position for the user's hand to pull out the water tank. When the water tank is stuck and cannot be ejected, the user presses the blocking member 2 to insert it into the slide 31, and then the hand can reach into the opening and contact the inner wall of the front panel 311. The inner wall can serve as a fulcrum, and the user can apply an outward pulling force to the water tank through this fulcrum, easily removing the stuck water tank from the cooking device. The opening is located in the front panel 311, which conforms to the user's operating habits.

[0055] The location of the opening of the slide 31 on the front panel 311 can be designed according to actual needs. For example, the opening of the slide 31 can be located in the lower part of the front panel 311, near the bottom of the water tank. With this arrangement, the opening in the lower part conforms to the user's natural bending or reaching posture, eliminating the need to deliberately raise or lower their head, making operation more convenient.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment, a limiting member 23 is provided on the outer periphery of the shield 2. In the closed state, the limiting member 23 abuts against the inner wall of the front panel 311. In the illustrated embodiment, the limiting member 23 is a limiting wall surrounding the shield 2. With this configuration, the limiting member 23 abuts against the inner wall of the front panel 311 in the closed state, which can restrict the shield 2 from sliding out of the slide groove 31, preventing the shield 2 from protruding from the opening of the slide groove 31 due to excessive elasticity of the reset member or other external forces, ensuring that the shielding surface 21 is flush with the operating surface 3 in the closed state, maintaining the overall integrity of the water tank's appearance; the limiting wall surrounding the shield 2 can limit the shield 2 from the entire outer periphery of the shield 2, making the limiting effect more uniform and reliable, and avoiding local protrusion of the shield 2; at the same time, the limiting member 23 can also enhance the structural strength of the shield 2, preventing the shield 2 from deforming during long-term use.

[0057] In another embodiment, the limiting element 23 is a limiting block. The shape, number, and arrangement of the limiting blocks can be designed according to actual needs. With this configuration, the limiting blocks, as limiting elements 23, offer high flexibility in shape, number, and arrangement. They can be customized according to the specific structure of the water tank, the size of the shielding element 2, and the required limiting strength. For example, when the shielding element 2 is small, a single limiting block can be placed in the center; when the shielding element 2 is large, multiple limiting blocks distributed along the outer periphery can be placed. The shape of the limiting blocks can be designed as circular, square, etc., to adapt to different installation spaces and limiting requirements. This flexibility allows the limiting structure to better adapt to water tanks of different specifications, improving the versatility and applicability of the water tank structure.

[0058] In one embodiment, the water tank also includes a press-and-rebound structure disposed between the water tank and the outer shell. This configuration makes the press-and-rebound structure identical to those in existing water tank technologies, and will not be described in detail here. When the press-and-rebound structure is functioning normally, the user can eject the water tank using a conventional pressing method, meeting daily convenience needs. If the press-and-rebound structure fails due to quality issues, assembly errors, or long-term use, causing the water tank to become stuck and unable to eject, the user can press the blocking part 2 and use the opening to forcefully remove the water tank. This effectively solves the problem of water tank jamming after the press-and-rebound structure fails, improves the reliability of the water tank, and avoids the water tank becoming unusable or difficult to repair due to the failure of a single press-and-rebound structure.

[0059] Furthermore, the water tank can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the water tank to perform corresponding operations, thereby realizing intelligent regulation of the water tank and improving the user experience.

[0060] This application also provides a cooking device including the aforementioned water tank. With this configuration, the cooking device, by employing the aforementioned water tank, effectively solves the problems of stuck and difficult-to-remove external water tanks and cumbersome replacements in existing cooking devices. When the water tank's press-and-rebound structure is functioning normally, the user can pop out the water tank to add water using a conventional pressing method, meeting daily usage needs. When the press-and-rebound structure fails, causing the water tank to become stuck, the user can remove the stuck water tank using the shield 2 and the sliding groove 31 structure on the water tank, without disassembling the entire cooking device or the water tank base, saving repair and replacement time. Simultaneously, the water tank's structural design ensures the overall integrity of the cooking device's appearance, enhancing its aesthetic appeal. Furthermore, the cooking device can select water tanks with different structures (such as different numbers of telescopic components 1, different types of reset components, etc.) according to actual needs, adapting to different models and functions of cooking devices.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
