Abstract

This utility model relates to an exhaust structure and cooking equipment. The exhaust structure includes: a stove with a first interface connected to an exhaust pipe; a cooking chamber with a second interface; and an extended exhaust pipe connecting the second interface and the exhaust pipe. When the cooking chamber is offset relative to the stove along a positive direction in a first direction, the length of the extended exhaust pipe is b+c. When the cooking chamber is offset relative to the stove along a negative direction in the first direction, if b < a, the length of the extended exhaust pipe is b; if a < b < 2a, the length of the extended exhaust pipe is 2a-b; if b > 2a, the length of the extended exhaust pipe is b-2a+c.

Description

Technical Field

[0001] This utility model relates to the technical field of cooking equipment, and in particular to an exhaust structure and cooking equipment. Background Technology

[0002] During the installation of integrated cooking equipment such as stoves, steamers, and ovens, it is necessary to connect the top stove and the bottom cooking chamber through the exhaust pipe.

[0003] Currently, the exhaust pipes that come with integrated cooking equipment are mostly designed to fit the cooktop and cooking cabinet facing each other. Therefore, when the cooktop and cooking cabinet need to be installed in a misaligned manner due to limited installation space or customer requirements, the exhaust pipe may be too short, making installation difficult or even impossible. On the other hand, if the exhaust pipe is lengthened directly, water may accumulate in the pipe during the gas pipeline process. Utility Model Content

[0004] Therefore, it is necessary to provide an exhaust structure and cooking device that can meet the requirements of misaligned installation, is easy to install, and does not easily accumulate water, in order to address the problems of installation difficulties and water accumulation in the exhaust pipes of current integrated cooking equipment when the stove and cooking cabinet are installed in a misaligned manner.

[0005] This application first provides an exhaust structure, including a stove with a first interface connected to a stove exhaust pipe; a cooking chamber with a second interface; and an extended exhaust pipe connecting the second interface and the stove exhaust pipe. When the cooking chamber is offset relative to the stove along a positive direction in a first direction, the length of the extended exhaust pipe is b+c. When the cooking chamber is offset relative to the stove along a negative direction in the first direction, if b < a, the length of the extended exhaust pipe is b; if a < b < 2a, the length of the extended exhaust pipe is 2a-b; if b > 2a, the length of the extended exhaust pipe is b-2a+c. Wherein, when the stove and the cooking chamber are directly opposite each other, the second interface is located on the positive side of the first interface along the first direction; a is the distance between the first interface and the second interface along the first direction when the stove and the cooking chamber are directly opposite each other; b is the offset of the cooking chamber relative to the stove along the first direction; and c is the installation allowance.

[0006] In one embodiment, when the cooking chamber is offset from the stove in the positive direction of the first direction, and when the cooking chamber is offset from the stove in the negative direction of the first direction and b > 2a, the stove exhaust pipe and the extended exhaust pipe are collinear.

[0007] In one embodiment, the installation allowance c ranges from 25mm to 75mm.

[0008] In one embodiment, the installation allowance c is 50mm.

[0009] In one embodiment, when the cooking enclosure is offset from the stove in the negative direction of the first direction and b < a or a < b < 2a, the stove exhaust pipe and the axis of the extended exhaust pipe form an angle, and their projections in the vertical direction at least partially overlap.

[0010] In one embodiment, when b < a, one end of the stove exhaust pipe is connected to the first interface, and the other end extends in the positive direction of the first direction to connect with one end of the extended exhaust pipe, and the other end of the extended exhaust pipe extends in the negative direction of the first direction to connect with the second interface. When a < b < 2a, one end of the stove exhaust pipe is connected to the first interface, and the other end extends to the negative side of the first direction to connect to one end of the extended exhaust pipe. The other end of the extended exhaust pipe extends to the positive side of the first direction to connect to the second interface.

[0011] In one embodiment, the interconnecting ends of the stove exhaust pipe and / or the extended exhaust pipe are formed with a bent section, the axis of which is perpendicular to the horizontal plane.

[0012] In one embodiment, the axes of both the stove exhaust pipe and the extended exhaust pipe are inclined relative to the horizontal plane.

[0013] In one embodiment, the extended exhaust pipe includes an exhaust section and an interface section connected to one end of the exhaust section. The inner diameter of the exhaust section is larger than that of the interface section. The exhaust section is connected to the stove exhaust pipe, and the interface section is connected to the second interface.

[0014] This application first provides a cooking device, including the exhaust structure described above.

[0015] The aforementioned exhaust structure, by adding extended exhaust pipes of different sizes according to the offset direction and offset distance, can meet the installation requirements by using the shortest possible extended exhaust pipe when the stove and cooking cabinet need to be installed out of alignment. This effectively solves the problem of exhaust pipe length matching and the risk of water retention in the pipe when integrated cooking equipment is installed out of alignment.

[0024] Please combine Figures 1 to 4As shown, this application first provides an exhaust structure, including a stove 10 with a first interface 11 connected to a stove exhaust pipe 12; a cooking chamber 20 with a second interface 21; and a flexible extended exhaust pipe 30 connected to the second interface 21 and the stove exhaust pipe 12; when the cooking chamber 20 is offset relative to the stove 10 along the positive direction of the first direction, the length of the extended exhaust pipe 30 is b+c; when the cooking chamber 20 is offset relative to the stove 10 along the negative direction of the first direction, if b < a, then the extended exhaust pipe 30... The length of the exhaust pipe 30 is b. If a < b < 2a, the length of the exhaust pipe 30 is extended to 2a-b. If b > 2a, the length of the exhaust pipe 30 is extended to b-2a+c. When the stove 10 and the cooking box 20 are facing each other, the second interface 21 is located on the positive side of the first interface 11 along the first direction. a is the distance between the first interface 11 and the second interface 21 along the first direction when the stove 10 and the cooking box 20 are facing each other. b is the offset of the cooking box 20 relative to the stove 10 along the first direction. c is the installation allowance.

[0025] In this application, references Figure 1 The stove exhaust pipe 12 is the exhaust pipe of a traditional integrated cooking device, used to connect the first interface 11 and the second interface 21 when the stove 10 and the cooking cabinet 20 are directly opposite each other; and when the stove 10 and the cooking cabinet 20 need to be installed in a staggered manner, refer to... Figure 2 , Figure 3 as well as Figure 4 By adding extension exhaust pipes 30 of different sizes according to the offset direction and offset distance, the installation requirements can be met by using the shortest possible extension exhaust pipe 30, thereby effectively solving the problem of exhaust pipe length matching and water retention hazards when integrated cooking equipment is installed in a misaligned manner.

[0026] Specifically, this application establishes a dynamic exhaust pipe length calculation system, which can accurately match the length of the extended exhaust pipe 30 according to the offset direction (positive / negative direction) and offset amount (b) of the cooking cabinet 20 relative to the stove 10, so as to achieve the shortest wiring installation and ensure that the extended exhaust pipe 30 is always at the theoretical minimum length, thus completely avoiding the condensate accumulation area caused by excessively long and sagging pipes.

[0027] For more specific details, please refer to Figure 2 When the cooking cabinet 20 is offset from the stove 10 along the positive direction of the first direction, the length of the extended exhaust pipe 30 is b+c. In this case, b is the theoretical minimum length of the extended exhaust pipe 30 required to connect the stove exhaust pipe 12 and the second interface 21. Based on this, by adding an installation allowance c, the difficulty of disassembling and assembling the exhaust pipe during installation and maintenance can be reduced to meet the needs of installation and subsequent gas maintenance. refer to Figure 3When the cooking cabinet 20 is offset from the stove 10 in the negative direction of the first direction and b > 2a, the length of the extended exhaust pipe 30 is b - 2a + c. Similarly, b - 2a is the theoretical minimum length of the extended exhaust pipe 30. The installation allowance c is increased to meet the gas maintenance needs in the later stage of installation. When the cooking cabinet 20 is offset from the stove 10 in the negative direction of the first direction and b < a (not shown in the figure), the length of the extended exhaust pipe 30 is b. At this time, b is the theoretical minimum length of the extended exhaust pipe 30 required to connect the stove exhaust pipe 12 and the second interface 21. Meanwhile, since the distance between the first interface 11 and the second interface 21 in the first direction is less than a, there will inevitably be some bends in the stove exhaust pipe 12 and the extended exhaust pipe 30. The bends indirectly increase the total length of the exhaust pipe. During installation and maintenance, the length of the exhaust pipe can be increased by straightening the bends to meet the installation and maintenance requirements. In other words, the length requirement can be met without increasing the installation allowance c. refer to Figure 4 When the cooking cabinet 20 is offset from the stove 10 in the negative direction of the first direction and a < b < 2a, the length of the extended exhaust pipe 30 is 2a-b. Similarly, 2a-b is the theoretical minimum length of the extended exhaust pipe 30. At this time, there is a partial bend between the stove exhaust pipe 12 and the extended exhaust pipe 30, so there is no need to increase the installation allowance c to meet the length requirement.

[0028] In addition, this application retains the exhaust pipe of traditional integrated cooking equipment (i.e., stove exhaust pipe 12), and only requires the addition of a single extension exhaust pipe 30 and cutting it according to the length calculated above to achieve full working condition coverage. Compared with the overall pipe replacement solution, it can effectively reduce material costs.

[0029] In some embodiments, the stove exhaust pipe 12 and the extended exhaust pipe 30 are flexible, including but not limited to corrugated pipes.

[0030] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, when the cooking chamber 20 is offset from the stove 10 in the positive direction of the first direction, and when the cooking chamber 20 is offset from the stove 10 in the negative direction of the first direction and b > 2a, the stove exhaust pipe 12 and the extended exhaust pipe 30 are collinear.

[0031] In some embodiments, the installation allowance c ranges from 25 mm to 75 mm. The installation allowance c is added to the theoretical minimum length of the extended exhaust pipe 30 to provide an operation allowance for installation and maintenance (such as facilitating disassembly, alignment or maintenance) in specific offset scenarios (positive offset or negative offset when b>2a); when there is a negative offset and b<a or a<b<2a, since the bent portions of the cooker exhaust pipe 12 and the extended exhaust pipe 30 can be temporarily straightened to provide extra length, it is not necessary to add the installation allowance c.

[0032] Therefore, by controlling the installation allowance c within 25 mm to 75 mm, the present application allows an installer to flexibly select the installation allowance c according to on-site conditions (such as installation space, offset b, maintenance frequency and other factors) on the one hand, and can avoid the increased water storage risk caused by an excessively long extended exhaust pipe 30 on the other hand.

[0033] Wherein, the minimum value of 25 mm can provide a basic operation allowance, ensure slight slack during pipe connection, and avoid excessive stretching or damage (such as deformation of the corrugated pipe) caused by strict alignment during installation, meanwhile, 25 mm only slightly increases the length, resulting in a low water storage risk; and the maximum value of 75 mm can provide a more sufficient operation space, which facilitates pipe disassembly during maintenance (such as gas inspection), and 75 mm is a critical value. If the installation allowance c>75 mm, the extended exhaust pipe 30 is prone to sagging under gravity, forming a low point in the horizontal installation section, which increases the risk of condensed water accumulation.

[0034] Preferably, the installation allowance c is 50 mm. Under the allowance of 50 mm, small movement of the pipe is allowed, which can meet the requirements of installation and maintenance, and the installation process is smooth.

[0035] Please refer to Figure 3 as shown, in some embodiments, when the cooking box body 20 is offset to the negative side of the cooker 10 along the first direction and b<a or a<b<2a, an included angle is formed between the axes of the cooker exhaust pipe 12 and the extended exhaust pipe 30, and the projections of the two along the vertical direction at least partially overlap; by forming a bend between the cooker exhaust pipe 12 and the extended exhaust pipe 30, the installation reliability, condensed water prevention and control, and operation convenience are balanced without increasing the installation allowance c.

[0036] Specifically, when b<a, one end of the cooker exhaust pipe 12 is connected to the first interface 11, the other end extends to the positive side of the first direction to connect with one end of the extended exhaust pipe 30, and the other end of the extended exhaust pipe 30 extends to the negative side of the first direction to connect with the second interface 21; When a < b < 2a, one end of the stove exhaust pipe 12 is connected to the first interface 11, and the other end extends to the negative side of the first direction to connect to one end of the extended exhaust pipe 30. The other end of the extended exhaust pipe 30 extends to the positive side of the first direction to connect to the second interface 21.

[0037] Further, please refer to Figure 3 As shown, the connecting ends of the stove exhaust pipe 12 and / or the extended exhaust pipe 30 are formed with a bent section 121, the axis of which is perpendicular to the horizontal plane. The presence of the bent section 121 can replace the acute angle between the stove exhaust pipe 12 and the extended exhaust pipe 30 with two obtuse angles, thereby reducing the possibility of condensate remaining at the bend.

[0038] In some embodiments, the axes of the stove exhaust pipe 12 and the extended exhaust pipe 30 are both inclined relative to the horizontal plane, that is, to ensure that the stove exhaust pipe 12 and the extended exhaust pipe 30 always have an inclination relative to the horizontal plane, so as to avoid water accumulation.

[0039] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the extended exhaust pipe 30 includes an exhaust section 31 and an interface section 32 connected to one end of the exhaust section 31. The inner diameter of the exhaust section 31 is larger than that of the interface section 32. The exhaust section 31 is connected to the stove exhaust pipe 12, and the interface section 32 is connected to the second interface 21.

[0040] Since the inner diameter of the exhaust section 31 is larger than that of the interface section 32, even if there is inevitably some water retention and water blowing phenomenon in the exhaust section 31, the remaining cross-sectional area in the exhaust section 31 can meet the normal ventilation requirements and ensure that the steam passage is unobstructed.

[0041] In some embodiments, the aperture of interface segment 32 is adapted to a conventional machine connector.

[0042] This application first provides a cooking device, including the exhaust structure described above.

[0043] The aforementioned cooking equipment 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 cooking equipment to perform corresponding operations, thereby realizing intelligent control of the cooking equipment and improving the user experience.

[0044] 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.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
