Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a downdraft stove. Background Technology

[0002] Most existing shops adopt a single model, offering either a hot pot restaurant or a barbecue restaurant, or providing individual hot pots for each person while barbecuing. This results in the need for multiple layouts when designing the seating arrangement. For example, a four-person table might require a layout with four individual hot pots and one barbecue grill. However, sometimes the number of people cannot be specified. If five people come, a six-person table would be needed, making it difficult to add seats and extremely inconvenient. Considering safety factors, most grills are fixed and cannot be moved, making the cleaning process troublesome.

[0003] Therefore, an embedded hot pot and grill combination pot was designed, as disclosed in patent 202323259776.9, which includes: a placement cylinder, which is a concave cylindrical shape; an induction cooker, which is placed at the center of the inner cylinder of the placement cylinder, and the outer side of the upper end face of the placement cylinder is provided with an edge; and a grilling assembly, which includes a heating component disposed between the side wall of the induction cooker and the inner wall of the placement cylinder, and a grilling plate located above and connected to the heating component, the grilling plate being annular, the outer diameter of the grilling plate being equal to the inner wall of the placement cylinder, and the inner diameter of the grilling plate being equal to the maximum outer diameter of the induction cooker. By placing the induction cooker at the center of the placement cylinder and placing the grilling plate outside the induction cooker, the grilling plate and the induction cooker can be combined. Both the grilling plate and the induction cooker can be easily disassembled, thereby reducing the difficulty of subsequent cleaning and solving the problem that hot pots on the market have induction cookers but no grilling, and grilling plates on the market have induction cookers but no induction cookers.

[0004] However, problems still exist in actual use. During the grilling and hot pot process, the smoke generated on the heating plate is also discharged upwards, which will cause the meat to be contaminated with the grilling smoke and affect the taste. In addition, the heat generated by the electric heating rod will be lost quickly, reducing the utilization rate. When the oil accumulated in the oil drain hole flows into the oil collection box, it is easily affected by the hot airflow and flows to the lower plate. Utility Model Content

[0005] This utility model provides a downdraft stove, which solves the problems of existing technology where the smoke generated on the heating plate is also discharged upwards, causing the meat to be contaminated with barbecue smoke during hot pot, affecting the taste. In addition, the heat generated by the electric heating rod is quickly dissipated, reducing the utilization rate, and the oil accumulated in the oil drain hole is easily affected by the hot airflow and flows onto the lower plate when flowing into the oil storage box.

[0006] This utility model provides the following technical solution:

[0007] A downdraft stove includes a placement cylinder with an annular bottom plate. A supporting ring wall is formed along the inner edge of the bottom plate. An exhaust port is located on the bottom plate, and a peripheral wall is formed along the outer edge. A layer is formed within the peripheral wall, and multiple exhaust holes and heat dissipation holes are connected to the layer on the inner side of the peripheral wall. The exhaust holes are located above the heat dissipation holes. An mounting plate is provided on the bottom plate. The mounting plate includes a central supporting sleeve and a mounting groove on the outer side of the supporting sleeve. An electric heating element is installed in the mounting groove, and a heating plate is installed above the mounting groove. The outer side of the heating plate contacts the peripheral wall of the placement cylinder. The heating plate is located between the exhaust holes and the heat dissipation holes. A cylindrical space for installing an induction cooker is left at the center of the heating plate and the supporting sleeve.

[0008] In one possible implementation, the placement cylinder, mounting plate, and heating plate are coaxial.

[0009] In one possible implementation, a gap is left between the placement cylinder support ring wall and the support sleeve so that the placement cylinder support ring wall can support the induction cooker.

[0010] In one possible implementation, the mounting plate is equipped with a plurality of mounting plates, and the mounting plates are equipped with electric heating rods connected to a power source.

[0011] In one possible implementation, a limiting component is provided between the lower side of the heating plate and the mounting plate to restrict translation.

[0012] In one possible implementation, the heating plate has an annular oil collecting groove, the annular oil collecting groove has an oil drain port, and the oil drain port is connected to an oil storage box.

[0013] In one possible implementation, the oil storage box is mounted on the mounting plate, and the oil storage box and the electric heating rod are arranged to avoid each other.

[0014] In one possible implementation, a power supply box is also installed on the underside of the mounting plate. The head and tail ends of the electric heating rod extend into the power supply box and are connected to an external power source. The power supply box is provided with a cable inlet and heat dissipation holes.

[0015] In one possible implementation, the size of the exhaust port is smaller than the size of the heat dissipation hole of the placement cylinder, thereby controlling the flow rate and direction of the flue gas and ensuring that the flue gas can flow along a predetermined path. The exhaust port is located on the upper side of the heating plate, and the heat dissipation hole of the placement cylinder is located on the lower side of the heating plate. When exhausting the flue gas downwards, the flue gas enters the exhaust port laterally from the heating plate, flows vertically downwards within the interlayer, flows horizontally out through the heat dissipation hole of the placement cylinder on the lower side, and finally exits vertically from the exhaust port, forming a tortuous flue gas flow channel. This can improve thermal efficiency or increase the time for harmful substances in the flue gas to be filtered and purified. The heat dissipation hole of the placement cylinder not only helps to exhaust the flue gas, but may also play a role in heat dissipation, preventing the equipment from overheating.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In this utility model, the smoke generated during grilling on the heating plate can be quickly removed through the smoke vent, interlayer, heat dissipation vent, and air extraction port of the placement cylinder, thus preventing the smoke from affecting the hot pot in the middle.

[0018] By setting up an installation plate, the electric heating rod is installed into the installation slot of the installation plate, and the installation slot and the heating plate form a ring-shaped sealed space, which can prevent the heat from being lost quickly and prevent the heat from directly affecting the induction cooker in the center and the power supply box, thereby improving the heat utilization efficiency.

[0019] The heating plate is equipped with an oil drain port, and the oil drain port has a downward extension section that extends into the oil collection box located at the bottom of the heating plate. Therefore, the grease collected through the oil collection tank will flow directly into the oil collection box and will not cause contamination to the lower side of the heating plate or the mounting plate.

[0045] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0046] like Figures 1-16 As shown, this application provides a downdraft stove, including a placement cylinder 1. The placement cylinder 1 is provided with an annular placement cylinder bottom plate 110. A placement cylinder support ring wall 105 is provided along the inner edge of the placement cylinder bottom plate 110. An exhaust port 106 is provided on the placement cylinder bottom plate 110. A placement cylinder peripheral wall is provided along the outer edge of the placement cylinder bottom plate 110. A sandwich layer 107 is provided inside the peripheral wall. A plurality of smoke exhaust holes 103 and a placement cylinder heat dissipation hole 104 communicating with the sandwich layer 107 are provided on the inner side of the peripheral wall. 03 is located above the heat dissipation hole 104 of the placement cylinder. The bottom plate 110 of the placement cylinder is provided with a mounting plate 3. The mounting plate 3 includes a support sleeve 302 in the middle and a mounting groove installed on the outside of the support sleeve 302. An electric heating component is installed in the mounting groove. A heating plate 2 is installed on the upper part of the mounting groove. The outer side of the heating plate 2 is in contact with the peripheral wall of the placement cylinder 1. The heating plate 2 is located between the smoke vent 103 and the heat dissipation hole 104 of the placement cylinder. A cylindrical space for installing an induction cooker is left at the center of the heating plate 2 and the support sleeve 302.

[0047] Specifically, the size of the exhaust port 103 is smaller than the size of the heat dissipation port 104 of the placement cylinder, thereby controlling the flow rate and direction of the flue gas and ensuring that the flue gas can flow along a predetermined path. The exhaust port 103 is located on the upper side of the heating plate, and the heat dissipation port 104 of the placement cylinder is located on the lower side of the heating plate 2. When exhausting the flue gas downwards, the flue gas enters the exhaust port 103 horizontally from the heating plate 2, flows vertically downwards in the interlayer, flows horizontally out through the heat dissipation port 104 of the placement cylinder on the lower side, and finally exits vertically from the exhaust port, forming a tortuous flue gas flow channel. This can improve thermal efficiency or increase the time for harmful substances in the flue gas to be filtered and purified. The heat dissipation port of the placement cylinder not only helps to exhaust the flue gas, but may also play a role in heat dissipation to prevent the equipment from overheating.

[0048] Specifically, such as Figures 4-6 As shown, the placement cylinder 1 includes a circular placement cylinder bottom plate 110. The outer side of the placement cylinder bottom plate 110 is provided with a vertically upward folded outer wall 101 and an inner wall 109. A gap is left between the outer wall 101 and the inner wall 109 to form a sandwich 107. The top of the outer wall 101 and the inner wall 109 is provided with a horizontally outward folded extension 102. On the one hand, it can seal the top of the outer wall 101 and the inner wall 109. On the other hand, the folded extension 102 forms a ring-shaped hanging structure. During installation, a circular opening is made at the installation position, and then the ring-shaped hanging structure, i.e., the folded extension 102, is hung at the circular opening to complete the installation of the stove.

[0049] Multiple smoke exhaust holes 103 are provided on the upper part of the inner wall 109 of the placement cylinder, and multiple heat dissipation holes 104 are provided on the lower part of the inner wall 109 of the placement cylinder. The multiple smoke exhaust holes 103 are connected to the interlayer 107, and the multiple heat dissipation holes 104 are connected to the interlayer 107. A vertically upward folded placement cylinder support ring wall 105 is provided on the inner side of the placement cylinder bottom plate 110. Multiple air extraction ports 106 are also provided on the placement cylinder bottom plate 110. The air extraction ports 106 are connected downward to the air extraction port extension section 108. The air extraction ports 106 and the air extraction port extension section 108 are located between the inner wall 109 of the placement cylinder and the placement cylinder support ring wall 105. A wire passage 111 is also installed on the placement cylinder bottom plate 110.

[0050] Therefore, the gas inside the interlayer 107 can be extracted through the heat dissipation hole 104 of the placement cylinder, and the interlayer 107 can extract the gas at the exhaust hole 103 through the exhaust hole 103. Therefore, when the baking pan on the heating plate 2 is grilling and producing smoke, the smoke will not float upward, but will enter the interlayer 107 through the exhaust hole 103 and finally enter the annular space formed by the mounting plate 3 and the placement cylinder 1 through the heat dissipation hole 104 of the placement cylinder, and finally be extracted by the air extraction port 106 and the air extraction port extension 108 on the bottom plate 110 of the placement cylinder.

[0051] An installation plate 3 is provided on the bottom plate 110 of the placement cylinder. The installation plate 3 includes a support sleeve 302 in the middle. An annular installation groove is fixed on the outer wall of the support sleeve 302. An electric heating rod 6 is installed in the annular installation groove. The support sleeve 302, the annular installation groove and the inner wall 109 of the placement cylinder form an annular cavity. The annular cavity is connected to the interlayer 107 through the heat dissipation hole 104 of the placement cylinder. The annular cavity is connected to the air extraction device for air extraction through the air extraction port 106 and the air extraction port extension 108 on the bottom plate 110 of the placement cylinder.

[0052] The annular mounting groove includes a mounting plate base 303. The outer side of the mounting plate base 303 is provided with a vertically upward folded outer edge 301, and the inner side of the mounting plate base 303 is provided with a vertically upward folded inner edge 305. The inner edge 305 is fixedly connected to the outer wall of the support sleeve 302. An oil storage box avoidance opening 309 is provided to avoid the oil storage box 4. A power supply box mounting hole 307 is provided to install the power supply box 5. An electric heating rod inlet 306 and an electric heating rod outlet 308 are also provided. The electric heating rod 6 is inserted through the electric heating rod inlet 306 and laid along the laying direction of the mounting plate 7. Finally, the electric heating rod 6 is inserted through the electric heating rod outlet 308. The first and last ends of the electric heating rod 6 extend into the power supply box 5 below.

[0053] Furthermore, the placement cylinder 1, the mounting plate 3, and the heating plate 2 are coaxial.

[0054] Specifically, such as Figure 1-3 As shown, the outer side wall 101, inner side wall 109, and support ring wall 105 of the placement cylinder 1 are all cylindrical, and the bottom plate 110 of the placement cylinder is annular. The bottom plate 110, the outer side wall 101, the inner side wall 109, and the support ring wall 105 of the placement cylinder are coaxial.

[0055] The outer edge 301 and inner edge 305 of the mounting plate 3 are circular annular circumferential walls, the bottom plate 303 of the mounting plate is a circular annular plate, and the support sleeve 302 is cylindrical. The outer edge 301, inner edge 305, bottom plate 303, and support sleeve 302 of the mounting plate are coaxial.

[0056] When the mounting plate 3 is placed on the placement cylinder 1, the mounting plate 3 and the placement cylinder 1 are coaxial;

[0057] The heating plate 2 is a circular plate. When the heating plate 2 is set on the mounting plate 3, the heating plate 2 and the mounting plate 3 are coaxial.

[0058] Furthermore, a gap is left between the placement cylinder support ring wall 105 and the support sleeve 302 so that the placement cylinder support ring wall 105 can support the induction cooker.

[0059] Specifically, such as Figure 7As shown, a placement cylinder support ring wall 105 is provided in the middle of the placement cylinder 1, and the top of the placement cylinder support ring wall 105 is lower than the top of the placement cylinder 1, such as... Figure 3 As shown, the placement cylinder support ring wall 105 and the support sleeve 302 are coaxial and have a gap. When the induction cooker is placed on the placement cylinder support ring wall 105, it is to ensure that there is a gap between the outer wall of the induction cooker and the placement cylinder support ring wall 105.

[0060] Furthermore, multiple mounting plates 7 are mounted on the mounting disk 3, and electric heating rods 6 connected to the power supply are mounted on the mounting plates 7.

[0061] Specifically, such as Figure 13-14 As shown, the mounting base plate 303 has multiple mounting slots 304 for fixing mounting plates 7, such as... Figure 16 As shown, the mounting plate 7 includes a mounting plate body with two outward-facing L-shaped mounting plate feet at the bottom of the mounting plate body. An electric heating rod fixing port is provided on the mounting plate body. A fixing port adjustment groove 704 that extends to the outside is provided on one side of the electric heating rod fixing port. The mounting plate feet are inserted into the mounting slots 304 of the mounting plate 7 to fix the mounting plate 7, thereby completing the fixation of the mounting plate 7 and the mounting plate 3. The electric heating rod 6 passes through the electric heating rod fixing port. The size of the electric heating rod fixing port is adjusted by the fixing port adjustment groove 704, so that the size of the electric heating rod fixing port is adapted to the size of the electric heating rod 6.

[0062] Furthermore, a limiting component is provided between the lower side of the heating plate 2 and the mounting plate 3 to restrict translation.

[0063] Specifically, such as Figure 8-9 As shown, an outer limiting ring 210 and an inner limiting ring 211 are provided on the lower side of the heating plate base plate 208. The inner diameter of the outer limiting ring 210 is adapted to the outer diameter of the outer extension edge 301 of the mounting plate, and the outer diameter of the inner limiting ring 211 is adapted to the inner diameter of the support sleeve 302, so that when the heating plate 2 is installed on the mounting plate 3, the mounting plate 3 can limit the heating plate 2.

[0064] Furthermore, an annular oil collecting groove is provided on the heating plate 2, and an oil drain port 207 is provided on the annular oil collecting groove. The oil drain port 207 is connected to an oil storage box 4.

[0065] Specifically, such as Figure 8-9As shown, the heating plate 2 includes an annular heating plate base plate 208. An outer edge 201 of the heating plate is provided on the outer side of the heating plate base plate 208. A pair of heating plate lifting parts 202 are symmetrically arranged on the outer edge 201. An inner edge 203 of the heating plate is provided on the inner side of the heating plate base plate 208. An annular outer oil collection groove 204 and an inner oil collection groove 205 are provided on the heating plate base plate 208. A plurality of connecting grooves 206 are provided between the outer oil collection groove 204 and the inner oil collection groove 205. An oil drain port 207 for draining oil is provided on the outer oil collection groove 204. An oil drain port extension section 209 is provided downward on the oil drain port 207. An oil storage box 4 is installed in the oil storage box clearance opening 309. The oil drain port extension section 209 extends into the top opening of the oil storage box 4.

[0066] Furthermore, the oil storage box 4 is installed on the mounting plate 3, and the oil storage box 4 and the electric heating rod 6 are arranged to avoid each other.

[0067] Specifically, such as Figure 12-13 As shown, an oil collection box clearance opening 309 is provided on the mounting plate 303, and an oil collection box 4 is installed inside the oil collection box clearance opening 309, as shown. Figure 10 As shown, when the oil storage box 4 is installed at the oil storage box clearance opening 309, the upper opening of the oil storage box 4 is higher than the mounting plate bottom plate 303, and at the same time, it is lower than the top of the support sleeve 302, so that the oil drain port extension 209 on the heating plate 2 can extend into the oil storage box 4, while the oil storage box 4 will not contact the heating plate 2.

[0068] Furthermore, a power supply box 5 is also installed on the lower side of the mounting plate 3. The first and second ends of the electric heating rod 6 extend into the power supply box 5 and are connected to the external power supply. The power supply box 5 is equipped with a cable inlet and a power supply box heat dissipation hole.

[0069] Specifically, such as Figure 10 , Figure 12 As shown, the power supply box 5 is configured as a rectangular box with an opening at the top. Two folded edges are provided at the top of the rectangular box, and through holes are opened on the folded edges. The rectangular box is fixed to the power supply box mounting hole 307 by bolts. The bottom of the rectangular box is provided with the power cord inlet and outlet. The right side wall of the rectangular box is provided with the power supply box heat dissipation hole. The rectangular box is located in the annular space between the mounting plate 3 and the placement cylinder 1.
