Description

Technical Field

[0001] This invention relates to the field of integrated stove technology, and in particular to a duct structure and an integrated stove. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines multiple functions such as a range hood, gas stove, disinfection cabinet, and steam oven. It has advantages such as saving space, excellent smoke extraction, energy saving, low consumption, and environmental protection.

[0003] The original standard-length integrated cooktops combined a range hood, gas stove, disinfection cabinet, and steam oven, among other functions. However, the traditional integrated cooktop's air duct system, with its rear-mounted volute assembly and excessively wide duct, resulted in inefficient use of space in the steam oven and regular oven, leading to a very cramped interior. To accommodate smaller apartments, the internal space of integrated cooktops would need to be even more limited. Current solutions include reducing the number of functional modules to decrease the number of internal components, such as eliminating the steam oven module to save space. This creates a conflict between demand and practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a duct structure that can improve space utilization.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The air duct structure includes,

[0007] The air duct plate, two of which are interlocked to form an air cavity with an opening on one side,

[0008] Of the connecting edges of the two air duct plates adjacent to the opening, one is parallel to the first axis.

[0009] Another side gradually decreases in distance from the first axis along a direction away from the opening to form an inclined connecting edge (12);

[0010] The first axis is the central axis of the edge of the air duct plate that forms the opening, and the central axis is arranged along the air duct plate;

[0011] One of the air duct plates is provided with several connection ports for connecting external devices, and the several connection ports are connected to the air cavity.

[0012] Preferably, the angle between the inclined connecting edge and the first axis is 5°-15°.

[0013] Preferably, the edge of the air duct plate is bent to one side to form a bent edge, and the bent edges of two air duct plates are fastened together to form a connecting edge of the two air duct plates.

[0014] Preferably, the bends of the two duct plates have multiple inward recessed grooves at the bends, and the multiple recessed grooves are evenly spaced.

[0015] Preferably, the connection port includes a negative pressure port for connecting to an external negative pressure box and multiple docking ports for connecting to external functional modules. The negative pressure port is away from the opening, and the docking ports are close to the opening.

[0016] Preferably, a baffle is provided inside the air cavity, the baffle is located between the negative pressure port and the opening, and the baffle is arranged on the first axis and connects the two air duct plates.

[0017] Preferably, the device also includes a connecting base, which is a rectangular groove. The bottom of the connecting base is fixedly connected to the edge of the opening formed by the air duct plate. The inner bottom wall of the connecting base is provided with a notch that matches the opening. The inner side wall of the connecting base is provided with a reinforcing strip.

[0018] An integrated cooktop is also provided, including:

[0019] The base plate, two side panels on the base plate, and a back plate between the two side panels, the distance between the two side panels is 60-80cm, and the two side panels are provided with panel air outlets;

[0020] The air duct structure as described above; the air duct plate away from the connection port is arranged along the height direction of the back plate, and the air duct structure is connected to the two side panels;

[0021] A negative pressure box is provided inside, which is equipped with a detachable volute assembly. The negative pressure box has an air inlet, which is connected to one of the connection ports. Two negative pressure air outlets are provided on both sides of the air inlet, and the negative pressure air outlets are connected to the air outlet of the enclosure panel.

[0022] Preferably, the distance between the two side panels is 60-80cm.

[0023] Preferably, the distance between the negative pressure air outlet on one side of the inclined connecting edge and its opposite enclosure air outlet is greater than the distance between the negative pressure air outlet on the other side and its opposite enclosure air outlet.

[0024] The beneficial effects of this invention are:

[0025] By using an asymmetrical air duct structure on both sides, the connecting edge of one of the air duct plates in the air duct structure forms an inclined connecting edge, which forms a certain angle with the first axis at the end away from the opening. This allows the small-sized integrated stove to have a certain space between the inclined connecting edge and the internal wall of the integrated stove, leaving as much room as possible for the functional modules inside the integrated stove. This allows the small-sized integrated stove to integrate as many functional modules as possible, improving the user's quality of life. The air duct structure of the integrated stove can also further reduce noise. Attached Figure Description

Detailed Implementation

[0033] 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 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, and not all of the structures.

[0034] In the description of this invention, 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 invention based on the specific circumstances.

[0035] 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.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," and "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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0037] Current standard-length integrated cooktops include multiple functions such as range hood, gas stove, disinfection cabinet, and steam oven. However, in order to adapt to the design of small apartments, the size of integrated cooktops has been further reduced, resulting in the loss of functional modules and a decrease in quality of life.

[0038] like Figure 1-5 As shown, this embodiment provides a duct structure 10, which includes two duct plates 11. The two duct plates 11 are interlocked to form a duct cavity with an opening 19 on one side. The duct plate 11 has a first axis 111, which is the central axis of the edge of the duct plate 11 forming the opening 19. The central axis is arranged along the extension direction of the duct plate 11. One of the connecting edges of the two duct plates 11 adjacent to the opening 19 is parallel to the first axis 111. The distance between the other and the first axis 111 gradually decreases from one side of the opening 19 to the other side to form an inclined connecting edge 12. One of the duct plates 11 is provided with a plurality of connecting ports 13 for connecting external devices. The plurality of connecting ports 13 are connected to the ventilation cavity.

[0039] Therefore, through the asymmetrical air duct structure 10 on both sides, the connecting edge of one of the air duct plates 11 in the air duct structure 10 forms an inclined connecting edge 12, and forms a certain angle with the first axis 111 at the end away from the opening 19. When the air duct structure 10 is installed into the integrated stove, a certain space is formed between the inclined connecting edge 12 and the internal wall of the integrated stove. Without losing the original suction function of the air duct structure 10, as much space as possible can be reserved for the functional modules of the integrated stove to enrich the various functional modules of the small-sized integrated stove and improve the user's quality of life.

[0040] This embodiment will be described in detail below, such as Figure 1-5 As shown, the air duct structure 10 includes two interlocking air duct plates 11, which interlock to form an air cavity with an opening 19 on one side. Specifically, the edges of the air duct plates 11 are bent to one side to form bent edges 14. The bent edges 14 of the two air duct plates 11 are interlocked to form a connecting edge of the two air duct plates 11. The bent edges 14 increase the volume inside the air cavity, thereby increasing the airflow. More specifically, the bent edges 14 on the two air duct plates 11 have multiple inwardly recessed grooves 15 at the bends, which can form a reinforcing rib structure by indenting inward through the grooves 15, thereby improving the structural strength of the bends on the bent edges 14. In this embodiment, the multiple recessed grooves 15 are evenly spaced, and the recessed grooves 15 on the two air duct plates 11 are symmetrically arranged with respect to the connecting edge of the two air duct plates 11. Furthermore, to facilitate the connection between the two air duct plates 11, the edge of the bent edge 14 is bent away from the air duct plate 11 and has a roll welded edge, so that roll welding can be performed by butt welding of the opposite roll welded edges. Several process positioning holes are also provided on the roll welded edge for roll welding positioning.

[0041] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the duct plate 11 has a first axis 111, which is the central axis of the edge of the duct plate 11 forming the opening 19, and the central axis is set along the extension direction of the duct plate 11. One of the connecting edges of the two duct plates 11 adjacent to the opening 19 is parallel to the first axis 111; along the direction away from the opening 19, the distance of the other edge from the first axis 111 gradually decreases from the side connecting the opening to the other side, forming an inclined connecting edge 12. This makes the connecting edges of the duct plates 11 on both sides of the opening 19 asymmetrical with respect to the central axis, thus allowing for a larger space on one side of the inclined connecting edge 12 during installation, providing installation positions for other components. On this basis, the other side is set parallel to the central axis to maximize the airflow of the air cavity and minimize the reduction in suction effect. Specifically, the angle between the inclined connecting edge 12 and the first axis 111 is 5°-15°. Preferably, 10° can be selected.

[0042] One of the air duct plates 11 is provided with several connection ports 13 for connecting external devices, and the connection ports 13 are connected to the ventilation cavity. It can be understood that the connection ports 13 can be opened according to specific uses. Specifically, the connection port 13 includes a negative pressure port 131 for connecting to an external negative pressure box 40, and the negative pressure port 131 is away from the opening 19. In this embodiment, the negative pressure port 131 is a large elliptical flip hole for connecting to an external negative pressure machine; multiple interfaces 132 for connecting external functional modules are also provided, and the interfaces 132 are located between the first axis 111 and the inclined connecting edge 12; for example, but not limited to, circular flip holes for depressurization of the steam box and elliptical flip holes for heat dissipation of the steam oven fan; with the above structure, the connection port 13 is set on one side of the air duct plate 11, which allows the side of the air duct plate 11 without the connection port 13 to be attached to the back of the integrated stove, reducing the width of the air duct, thereby saving space and improving the space utilization rate. In addition, it has multiple heat dissipation holes, which are located on both sides of the first axis 111 to dissipate heat from the interior of the integrated stove. For example, the heat dissipation holes can be louvered holes. The volute assembly 41 is located on the side of the air duct plate 11 with the connection port 13, so that the volute assembly 41 is detached from the back of the integrated stove, and the air duct structure 10 is located at the back to avoid the problem of large air force loss when exhausting from the bottom. Furthermore, the air duct plate 11 with the connection port 13 also has multiple fixing holes for fixing the firewall probe. The positions of the heat dissipation holes and fixing holes can be adjusted according to the design, and no specific limitation is made here. In addition, the air duct structure 10 is also provided with an oil concentrator 17 communicating with the air cavity. The oil concentrator 17 is disposed through the connecting edge of the two air duct plates 11 opposite to the opening 19. In this embodiment, the oil concentrator 17 is disposed on the air duct plate 11 with the connection port 13, specifically on the bent edge 14 of the air duct plate 11 away from the opening 19.

[0043] like Figure 2As shown, the air duct structure 10 is also provided with a partition 16, which is fixed inside the air cavity. The partition 16 is located on the first axis 111 and connects two air duct plates 11. The partition 16 is located between the negative pressure port 131 and the opening 19. For example, the air duct plate 11 is provided with screw holes corresponding to the partition 16, and the partition 16 is fixed to the air duct plate 11 by screws. Through the partition 16, when the integrated stove is in operation, the external oil fumes are guided through the partition 16 from the opening 19 of the air cavity to the negative pressure port 131, making the air intake smoother and preventing the air from wandering around in the air duct, thereby reducing the noise generated when the air flows in the entire air duct structure 10. In addition, the partition 16 connects the two air duct plates 11, strengthens the air duct structure 10, reduces the noise generated by the resonance of the air duct structure 10, and further reduces the noise of the entire integrated stove with this air duct structure 10. The duct structure 10 also includes a connecting base 18, which is a rectangular groove. The bottom of the connecting base 18 is fixed to the edge of the opening 19 formed by the duct plate 11. In this embodiment, the length of the connecting base 18 is greater than the length of the opening 19, so that the connecting base 18 protrudes beyond the connecting edge of the two duct plates 11, providing an installation position for the connecting base 18 to be connected inside the integrated stove. Furthermore, the inner bottom wall of the connecting base 18 has a notch that matches the opening 19 to allow for the flow of oil fumes. In addition, reinforcing strips 181 are provided on the inner side wall of the connecting base 18 to increase the strength of the connecting base 18. The number of reinforcing strips 181 welded and the position of the inner side wall can be adjusted and are not specifically limited. Furthermore, the portion of the connecting base 18 that protrudes beyond the connecting edge of the two duct plates 11 has a wiring hole for wiring.

[0044] like Figures 3-5As shown, this embodiment also provides an integrated stove, which includes a base plate 20, two side panels 30 disposed on the base plate 20, and a back panel 80 between the two side panels 30. In this embodiment, the distance between the two side panels 30 is 60-80cm to accommodate small kitchens. The integrated stove also includes the aforementioned air duct structure 10. The air duct plate 11, away from the connection port 13, is disposed along the height direction of the back panel 80, and the air duct structure 10 is connected to the two side panels 30. In this embodiment, the connecting base 18 on the air duct structure 10 is connected to the two side panels 30. More specifically, the top of the two side panels 30 is provided with a support strip 50, and the portion of the connecting base 18 protruding from the connecting edge of the two air duct plates 11 is connected to the side panels 30 by a fixed support strip 50. For example, welding or screwing can be used. In order to make the air duct structure 10 more securely fixed in the integrated stove, the back panel 80 is connected to the air duct plate 11 away from the connection port 13, and a fixing frame 60 is also placed horizontally between the two side panels 30. The fixing frame 60 is connected and fixed to the air duct plate 11 with the connection port 13; that is, the fixing frame 60 and the back panel 80 clamp the air duct structure 10. The specific connection between the fixing frame 60 and the air duct plate 11 can be, but is not limited to, a screw connection.

[0045] The integrated cooktop also includes a negative pressure box 40, which has an air inlet 42. A detachable volute assembly 41 is housed within the negative pressure box 40; this volute assembly 41 is existing technology and will not be described in detail here. The air inlet 42 of the negative pressure box 40 connects to the negative pressure port 131 on the duct structure 10, and a duct sealing ring 44 can be installed at the connection point to ensure a sealed connection. Two opposing negative pressure air outlets 43 are located on either side of the air inlet 42. Specifically, the distance between the negative pressure air outlet 43 on one side of the inclined connecting edge 12 and its opposite side panel air outlet 31 is greater than the distance between the negative pressure air outlet 43 on the other side and its opposite side panel air outlet 31. This allows for a larger space on one side of the inclined connecting edge 12 to accommodate components such as the water tank 70 of the steam oven, improving the space utilization of the small-sized integrated cooktop and thus enhancing the user experience. Because the negative pressure box 40 is provided with two negative pressure air outlets 43, and the two opposite side panels 30 are provided with panel air outlets 31, the air outlet direction of the volute assembly 41 in the negative pressure box 40 can be adjusted according to the user's on-site installation conditions to select the negative pressure air outlets 43 with different directions, thereby improving compatibility. In this embodiment, the detachability of the volute assembly 41 means that the volute assembly 41 can be removed from the negative pressure box 40 to change the air outlet direction. The specific detachment method is not limited, and screw connection is possible but not limited to. Since there is a certain distance between the panel air outlets 31 and the negative pressure air outlets 43, the negative pressure box 40 is also provided with an air outlet seat 46 to connect the panel air outlets 31 and the negative pressure air outlets 43. Thus, the length of the air outlet seat 46 located on one side of the inclined connecting edge 12 is greater than the length of the air outlet seat 46 located on the other side; the air outlet seat 46 and the panel air outlets 31 and the negative pressure air outlets 43 are connected by a wind seat sealing ring 45.

[0046] Therefore, by using the aforementioned small-sized integrated stove, space can be reserved for the functional modules of the integrated stove as much as possible, so that a small-sized integrated stove can also integrate various functional modules, improve the user's quality of life, and further reduce noise.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. 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 the present invention should be included within the scope of protection of the claims of the present invention.
