Description

Technical Field

[0001] This invention relates to the field of kitchen appliances technology, specifically to a multi-functional liftable stove. Background Technology

[0002] A cooktop, as a cooking platform, typically consists of a heat-resistant cooktop, a burner (cooktop or induction cooker), and a storage cabinet underneath. The height of traditional fixed cooktops (usually 800mm-850mm) is designed based on statistical data of the average adult standing and operating the cooktop, but it is inherently unsuitable for certain groups of people.

[0003] To address the issue of cooktop height adaptability for people of different heights, designs for lift-up cooktops have been proposed in the market. For example, Chinese patent document CN109595659A discloses a lift-up integrated cooktop, which includes an integrated cooktop cabinet; a cooktop is mounted on the top of the cabinet; and a set of lifting components are respectively installed between the cooktop and the left and right sides of the cabinet. Each lifting component includes a lead screw, an upper crossbar fixed to the cooktop, and a lower crossbar fixed to the cabinet. Two first hinge seats are symmetrically arranged at the bottom of the front and rear ends of the upper crossbar and at the top of the front and rear ends of the lower crossbar. This lift-up integrated cooktop, by adjusting the height of the cooktop, can accommodate users of different heights, improving cooking comfort.

[0004] Ergonomic studies show that food preparation (such as chopping vegetables) and cooking (such as stir-frying) have different requirements for countertop height. The former requires a higher countertop to avoid bending over, while the latter requires a lower countertop for easier exertion. However, existing lift-up cooktops generally use an integrated adjustment system for the cooktop and food preparation countertop, resulting in the two heights not being able to independently adapt to their respective tasks. Therefore, it is necessary to optimize the design of a multi-functional lift-up cooktop to improve operational comfort and ergonomics for different cooking stages. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a multi-functional lifting stove. By decoupling the stove's height adjustment from the food preparation countertop height adjustment, and integrating the stove cavity based on the independent control of the stove's height, the invention achieves simultaneous concealment, cleaning, and disinfection of the stove, thus overcoming the technical deficiency in existing technologies where the height of food preparation and cooking cannot be independently adjusted.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A multi-functional lifting stove includes a base and a platform body. A stove is provided inside the platform body. A first lifting component for adjusting the height of the platform body is provided on the base. The first lifting component is signal-connected to a controller. A stove placement cavity is opened inside the platform body. The stove is vertically slidably connected to the stove placement cavity. A second lifting component for adjusting the height of the stove is provided at the bottom of the stove body. The second lifting component is signal-connected to the controller.

[0007] Sliding cover plates are slidably connected to both sides of the stove cavity on the platform. A transmission component is also provided inside the stove cavity. When the stove is lifted and displaced by the second lifting component, the transmission component drives the movement of the second lifting component to drive the two sliding cover plates to slide in a direction away from each other, so as to expose the stove inside the stove cavity.

[0008] The stove cavity is equipped with a cleaning component, which uses the mechanical movement of the transmission component to draw in and spray out the cleaning liquid. An ultraviolet disinfection component that is connected to the controller signal is also fixedly connected to the inner side wall of the stove cavity.

[0009] The technical principle of the above solution is as follows: The multi-functional lifting stove is driven by the first lifting component on the base to lift the entire platform to adjust the height of the food preparation surface. The second lifting component in the stove cavity of the platform drives the stove to move vertically to adjust the height of the cooking surface. The sliding cover plate on the platform corresponding to the two sides of the stove cavity is slidably connected to the second lifting component through the transmission component, so that the lifting action of the stove drives the sliding cover plate to open and close synchronously. The cleaning component is set in the stove cavity. Based on the motion signal of the transmission component, the quantitative cleaning liquid is drawn in and sprayed out, which, together with the bottom drain, forms a flushing circuit. At the same time, the ultraviolet disinfection component fixed on the inner side wall of the stove cavity is controlled by the controller, which together constitutes automatic cleaning and hygiene maintenance in the storage state.

[0010] The above approach has the following beneficial effects:

[0011] 1. This solution decouples the cooking surface height adjustment function of the stove from the food preparation surface height adjustment function of the countertop, allowing the two to independently adapt to the ergonomic differences in cutting and cooking operations for users of different heights, thereby improving operational comfort and human-machine adaptability in multi-tasking scenarios.

[0012] 2. This solution uses a transmission component to mechanically couple the lifting and lowering motion of the stove with the opening and closing action of the sliding cover, thereby achieving automated control of the stove's exposed and concealed states, maintaining operational continuity without the need for an additional power source.

[0013] 3. This solution uses signal linkage between the cleaning component and the transmission component to automatically complete surface rinsing and simultaneously start ultraviolet disinfection during the stove storage process, effectively solving the problem of untimely and incomplete cleaning of traditional stoves and reducing the maintenance burden on users.

[0014] 4. This solution uses a sliding cover to transform the stove cavity into a closed storage space when the stove is stored, integrating cleaning, disinfection, and sewage discharge functions. This achieves multi-functional utilization of unused vertical space and improves the integration of kitchen space and the overall efficiency of equipment.

[0015] Furthermore, the sliding cover includes an integrally molded countertop and vertical panels.

[0016] Beneficial effects: The integrated structure of the countertop and vertical panels allows the two sides of the countertop to fit together when the stove is fully retracted into the stove cavity, restoring the complete flatness of the countertop. At the same time, the two vertical panels fit together to form a seal against the inside of the stove cavity, effectively preventing dust and other foreign objects from entering the stove cavity and reducing the need for cleaning and maintenance.

[0017] Furthermore, the second lifting assembly includes two electrically controlled cylinders located inside the stove cavity. The two electrically controlled cylinders are symmetrically arranged inside the stove cavity, and the bottom of each electrically controlled cylinder is fixedly connected to the platform body.

[0018] Beneficial effects: Using an electric cylinder as the execution unit for adjusting the height of the stove, the vertical displacement of the stove is driven by the controller signal, which can ensure the force balance and smooth movement of the stove during the lifting process, and provide reliable power support for the decoupled adjustment of the stove height and the countertop height.

[0019] Furthermore, the transmission assembly includes a guide rod and a driven cylinder. The driven cylinder is rotatably connected to the top surface of the base. The top end of the driven cylinder extends through the platform body into the stove cavity. The guide rod is fixedly connected to the bottom of the stove. The guide rod is located inside the driven cylinder. A first lead screw pair is provided between the driven cylinder and the guide rod. The first lead screw pair is used to convert the linear motion of the guide rod into the rotational motion of the driven cylinder.

[0020] A gear is fixedly mounted on the outside of the driven cylinder, and racks are symmetrically meshed on the gear. Each rack is fixedly connected to a corresponding vertical plate.

[0021] Beneficial effects: By combining the guide rod, driven cylinder, and first lead screw pair, the linear motion of the stove's lifting and lowering is converted into the rotational motion of the driven cylinder. Then, through the meshing transmission of the gear fixed on the outside of the driven cylinder and the racks on both sides, the rotational motion is synchronously converted into the linear displacement of the sliding covers on both sides in opposite directions, realizing the automatic linkage between the lifting and lowering action of the stove and the opening and closing state of the sliding covers. The opening and closing of the covers and the exposure of the stove can be guaranteed without an independent drive source.

[0022] Furthermore, the first lead screw pair includes symmetrically distributed sliding heads fixedly connected to the outer wall of the guide rod, and symmetrical sliding grooves are provided on the inner wall of the driven cylinder, with each sliding head slidingly engaged in the corresponding sliding groove.

[0023] Beneficial effects: The first lead screw pair is formed by the combination of the sliding head and the sliding groove. The linear motion of the guide rod is accurately converted into the rotational motion of the driven cylinder by the limiting and guiding of the sliding head in the sliding groove. At the same time, the symmetrical layout can ensure the balance of torque transmission and the reliability of motion conversion.

[0024] Furthermore, the sliding groove includes a linear guide section and a helical guide section from top to bottom.

[0025] Beneficial effects: The design of the linear guide section and the spiral guide section divides the process of the stove rising from the bottom of the stove cavity into an opening section and a free adjustment section; that is, in the spiral guide section, the stove rises and drives the driven cylinder to rotate to open the cover, and after entering the linear guide section, the stove can be raised and lowered freely without affecting the state of the cover, which not only ensures the reliability of the opening and closing of the cover, but also gives the stove height adjustment flexibility.

[0026] Furthermore, the cleaning component includes a liquid storage drawer and a piston replenishment tank. The liquid storage drawer is embedded in the side wall of the platform and slidably connected to the platform. A delivery pipe is connected to one side wall of the liquid storage drawer. The end of the delivery pipe away from the liquid storage drawer is connected to the piston replenishment tank. A one-way liquid valve is provided in the delivery pipe. A driven piston is provided on the piston replenishment tank. The driven piston is used to convert the rotation of the gear into hydraulic pressure and flow direction adjustment in the piston replenishment tank.

[0027] The piston replenishment tank is connected to several spray heads, all of which are fixedly connected to the inner wall of the stove cavity.

[0028] Beneficial effects: The system consists of a liquid storage drawer, a delivery pipe, a one-way liquid valve, a piston-type liquid replenishment tank, and a spray head, which constitute the suction and spraying system for cleaning liquid. A driven piston is set up to convert the rotation of the gear into hydraulic regulation within the tank. When the gear rotates, the driven piston drives the piston to move, causing the piston-type liquid replenishment tank to alternately complete the suction and discharge actions. Finally, the cleaning liquid is sprayed directionally onto the surface of the stove through the spray head, realizing the mechanical linkage between the cleaning action and the movement of the stove.

[0029] Furthermore, the driven piston component includes a movable piston located inside the piston replenishment tank. The movable piston is coaxially and slidably engaged with the inner sidewall of the piston replenishment tank. A connecting rod is fixedly connected to the top of the movable piston. A driven wheel that meshes with a gear is provided at the top of the connecting rod. A second lead screw pair is provided between the driven wheel and the connecting rod. The second lead screw pair is used to convert the rotation of the driven wheel into the vertical linear displacement of the connecting rod.

[0030] Beneficial effects: The driven wheel and connecting rod, combined with the second lead screw pair, convert the rotational motion obtained by the driven wheel meshing with the gear into the vertical linear displacement of the connecting rod, thereby driving the moving piston to slide coaxially within the piston replenishment tank, providing stable pressure control for the quantitative absorption and directional spraying of the cleaning fluid.

[0031] Furthermore, arc-shaped sliding limit blocks are fixedly connected around the stove, and several through grooves corresponding to the shape and stroke of the sliding limit blocks are opened in the stove cavity.

[0032] Beneficial effects: The design of the arc-shaped sliding limit block, combined with the through groove, forms a sliding guide for the lifting and lowering of the stove. The sliding guide helps to suppress radial sway during the lifting and lowering process of the stove, ensuring the stability and positional accuracy of the stove's vertical movement. At the same time, the travel of the limit block and the through groove determines the maximum lifting height of the stove, allowing the stove to partially extend out of the stove cavity to adapt to the operating habits of different cooks, balancing stability and flexibility of use.

[0033] Furthermore, a piezoelectric sensor connected to the controller signal is fixedly connected to the bottom of the channel.

[0034] Beneficial effects: The design of the piezoelectric sensor allows the sliding limit block to move to the bottom of the channel as the cooking window closes and come into contact with the piezoelectric sensor under pressure. The piezoelectric sensor generates a piezoelectric signal that is transmitted to the controller. The controller then triggers the ultraviolet disinfection component based on the position detection signal, realizing automated disinfection start-up and shutdown control based on the physical position detection of the stove, thus improving the intelligence level and safety of the equipment.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The following detailed description illustrates the specific implementation method:

[0047] Example 1:

[0048] This embodiment provides a multi-functional lifting stove, such as Figure 1 and Figure 2As shown, the device includes a base 1 and a platform 2. The base 1 is equipped with a first lifting assembly 3 for adjusting the height of the platform 2. The first lifting assembly 3 is signal-connected to a controller. The first lifting assembly 3 includes symmetrical hydraulic cylinders 301. Symmetrical lifting columns 302 are fixedly connected to the base 1. The two hydraulic cylinders 301 are respectively fixedly connected to the lifting columns 302 by bolts. The platform 2 has lifting cavities 303 corresponding to the two lifting columns 302. The lifting columns 302 are slidably connected to the lifting cavities 303 via guide rail sliding pairs. The output ends of the hydraulic cylinders 301 are welded to the inner top wall of the lifting cavities 303. Both hydraulic cylinders 301 are signal-connected to the controller. The controller signals control the drive of the hydraulic cylinders 301 to achieve overall lifting adjustment of the platform 2, i.e., adjustment of the height of the tabletop (food preparation surface).

[0049] In particular, combination Figure 2 and Figure 3 As shown, the platform 2 has a stove cavity 4 inside, and a stove 5 is vertically slidably connected inside the stove cavity 4. The bottom of the stove 5 is provided with a second lifting component for adjusting the height of the stove 5. The second lifting component is connected to the controller signal. The second lifting component includes electric control cylinders 6 located inside the stove cavity 4 and arranged symmetrically. The bottom of each electric control cylinder 6 is fixed to the inner bottom wall of the stove cavity 4 by bolts. This design decouples the adjustment of the stove 5 height (i.e., the cooking surface height) from the adjustment of the platform height, allowing the stove 5 height to be adjusted according to the ergonomic requirements of cooking operations, adapting to the optimization needs of users of different heights for cooking posture. At the same time, the platform height can also be set independently to meet the ergonomic standards of operation scenarios such as food preparation and cleaning.

[0050] Based on the separate height adjustment of the stove 5 and the platform 2, this embodiment has a cooking window 201 on the platform 2 corresponding to the stove cavity 4 (e.g., Figure 1 As shown), both sides of the cooking window 201 are equipped with sliding covers 7. The sliding covers 7 are slidably connected to the side walls of the countertop 2 through a guide rail and guide groove structure. Specifically, in combination with... Figure 1 and Figure 3 As shown: The sliding cover 7 includes an integrally formed countertop 701 and a vertical plate 702. With this design, after cooking, the lifting stove proposed in this embodiment can completely store the stove 5 in the stove cavity 4. The two countertops 701 fit together to restore the complete flatness of the countertop 2, realizing the multi-functional practicality of the stove. At the same time, the two countertops 701 and the vertical plate 702 fit together to form a closed enclosure of the stove cavity 4. Compared with the conventional exposed stove 5, it can effectively prevent dust and other foreign objects from entering the stove cavity 4, reducing the need for cleaning and maintenance.

[0051] Furthermore, when the stove 5 is completely housed within the stove cavity 4, the top surface of the stove 5 and the inner wall of the stove cavity 4 together form a closed cavity structure. This cavity can utilize the top surface of the stove 5 as a support surface to store kitchen utensils such as woks and saucepans, thereby achieving effective utilization of vertical unused space when not in use.

[0052] The stove cavity 4 is equipped with a transmission component for automating the lifting and exposure of the stove 5, specifically combined with... Figure 3 and Figure 4 As shown:

[0053] The transmission assembly includes a guide rod 8 and a driven cylinder 9. The driven cylinder 9 is rotatably connected to the top surface of the base 1 via a bearing. The top of the driven cylinder 9 extends through the platform 2 into the stove cavity 4. The guide rod 8 is welded to the bottom of the stove 5 and is located inside the driven cylinder 9. A first lead screw pair is provided between the driven cylinder 9 and the guide rod 8 to convert the linear motion of the guide rod 8 into the rotational motion of the driven cylinder 9. A gear 10 is welded to the outside of the driven cylinder 9. A rack 11 is symmetrically meshed on the gear 10 (when the gear 10 rotates, the racks 11 on both sides are linearly displaced in opposite directions). The racks 11 are fixedly connected to the corresponding vertical plates 702. This design realizes the automated mechanical linkage between the lifting action of the stove 5 and the opening and closing state of the cooking window 201.

[0054] The first lead screw pair includes symmetrically distributed sliding heads 801 integrally formed on the outer wall of the guide rod 8. Symmetrical sliding grooves are provided on the inner wall of the driven cylinder 9. The sliding heads 801 are all slidably engaged in the corresponding sliding grooves (refer to the slider spiral groove mechanism of the guide rod 8, the linear displacement of the sliding head 801 on the guide rod 8 is based on the limit of the sliding groove and the sliding head 801 being in contact, driving the driven cylinder 9 to move); in particular, the sliding grooves all include a linear guide section 901 and a spiral guide section 902 from top to bottom, so that the process of the stove 5 rising from the bottom of the stove cavity 4 is divided into an opening section (i.e., the separation of the two side countertops 701 and the vertical plate 702) and a free adjustment section (i.e., the stove 5 can freely rise and fall in the stove cavity 4 without affecting the two side countertops 701 and the vertical plate 702).

[0055] Based on the movement of the stove 5 to the bottom of the stove cavity 4, this embodiment also includes a cleaning component inside the stove cavity 4. The cleaning component, based on the mechanical movement of the transmission component, achieves the absorption and spraying of cleaning liquid. A drain duct 12 is connected to the bottom of the stove cavity 4. Specifically, in conjunction with... Figure 5 and Figure 6 As shown:

[0056] The cleaning assembly includes a liquid storage drawer 13 and a piston replenishing tank 14. The liquid storage drawer 13 is embedded in the side wall of the platform 2 and is slidably connected to the platform 2. A delivery pipe 15 is connected to one side wall of the liquid storage drawer 13. The end of the delivery pipe 15 away from the liquid storage drawer 13 is connected to the piston replenishing tank 14. The piston replenishing tank 14 is embedded in the bottom wall of the platform 2. A one-way liquid valve 16 is provided in the delivery pipe 15. A driven piston 18 is provided on the piston replenishing tank 14. The driven piston 18 is used to convert the rotation of the gear 10 into hydraulic pressure and flow direction adjustment in the piston replenishing tank 14. The piston replenishing tank 14 is connected to a number of spray heads 17, and the spray heads 17 are all fixedly connected to the inner side wall of the stove cavity 4.

[0057] Driven piston component 18 includes a movable piston 1801 located inside piston replenishment tank 14. The movable piston 1801 is coaxially slidably engaged with the inner sidewall of piston replenishment tank 14. A connecting rod 1802 is welded to the top of the movable piston 1801. The top of the connecting rod 1802 is provided with a driven wheel 1803 that meshes with gear 10. A second lead screw pair is provided between the driven wheel 1803 and the connecting rod 1802. The second lead screw pair is used to convert the rotation of the driven wheel 1803 into the vertical linear displacement of the connecting rod 1802 (the second lead screw pair includes a sliding block integrally formed on the inner sidewall of the driven wheel 1803 and a spiral groove opened on the connecting rod 1802).

[0058] Based on the above structure, when gear 10 meshes and drives driven wheel 1803 to rotate and open cooking window 201, the rotation of driven wheel 1803 is converted by the second lead screw pair into the vertical rise of connecting rod 1802 and moving piston 1801, creating negative pressure in piston replenishment tank 14. Cleaning liquid is then drawn from storage drawer 13 into piston replenishment tank 14 via delivery pipe 15 through one-way valve 16. When stove 5 finishes cooking and descends to the bottom of stove cavity 4, and gear 10 drives driven wheel 1803 to rotate and close cooking window 201, the connection... The vertical descent of rod 1802 and moving piston 1801 causes the cleaning fluid in piston replenishment tank 14 to be sprayed out through spray head 17 to rinse the area around stove 5 (after rinsing, it flows out from drain 12). This makes the stove cavity 4 form a preliminary cleaning process where stove 5 is lowered while receiving the cleaning fluid sprayed from spray head 17. This achieves automatic synchronization between the cleaning of stove 5 and the opening and closing of cooking window 201. That is, automatic rinsing and cleaning is performed immediately after cooking, reducing the complexity of subsequent deep cleaning of stove 5 and reducing the formation of stubborn oil stains.

[0059] In addition, such as Figure 2 As shown, an ultraviolet disinfection component 19 connected to the controller signal is also embedded on the inner wall of the stove cavity 4. The ultraviolet disinfection component 19 uses ultraviolet light to disinfect the surface of the stove 5 and the interior of the closed cavity, thereby achieving the synergistic effect of automatic cleaning and hygiene maintenance when the equipment is idle.

[0060] Example 2:

[0061] As attached Figure 2 As shown, the difference from Embodiment 1 is that the stove 5 is fixedly connected with arc-shaped sliding limit blocks 20 on all four sides, and several through grooves 21 corresponding to the shape and stroke of the sliding limit blocks 20 are opened in the stove cavity 4. This structure suppresses the radial sway of the stove 5 during the lifting process by the circumferential limiting constraint of the sliding limit blocks 20, ensuring the stability and positional accuracy of the vertical movement of the stove 5. At the same time, the cooperation stroke of the sliding limit blocks 20 and the through grooves 21 determines the maximum lifting height of the stove 5, so that the stove 5 can partially extend out of the stove cavity 4 to accommodate the operating habits of some cooks who prefer the stove 5 to be higher than the countertop, thus taking into account both lifting stability and flexibility of usage scenarios.

[0062] Example 3:

[0063] As attached Figure 2 As shown, the difference from Embodiment 2 is that a piezoelectric sensor 22 connected to the controller signal is fixedly connected to the bottom of the through groove 21; when the sliding limit block 20 moves to the bottom of the through groove 21 and comes into contact with the piezoelectric sensor 22 and is pressed as the cooking window 201 closes, the piezoelectric sensor 22 generates a piezoelectric signal and transmits it to the controller. The controller generates an output command based on the generation of the piezoelectric signal to trigger the ultraviolet disinfection component 19 to start, thereby realizing the automatic disinfection start and stop control based on the physical position detection of the stove 5.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
