[0024] The embodiments of the present application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present application are described in detail below.

[0025] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] In the description of the present application, “plurality” means two or more.

[0027] In order to improve the utilization rate of waste heat of smoke, stoves in the related art usually add an energy-gathering ring structure on the pot rack and add a curved channel on the upper surface of the pot rack to increase the flow path of the smoke and improve the heat exchange between the smoke and the bottom of the pot. However, the smoke escaping from the gap between the stove and the pot is not utilized, and the heat of the smoke is not fully utilized.

[0028] The cooker 1 of the embodiment of the present application is additionally provided with a smoke guiding device 300 for guiding the flow direction of the smoke escaping from the gap between the cooker 1 and the cooker 2, thereby increasing the upward flow path of the escaping smoke, so as to increase the heat exchange between the smoke and the peripheral surface of the cooker 2, further utilize the waste heat of the smoke, improve the heat utilization rate of the escaping smoke, and make the heat efficiency of the cooker 2 further high and the heat loss smaller.

[0029] The cooker 1 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0030] like Figure 1-Figure 5As shown, the cooker 1 according to the embodiment of the present application includes a pot rack 100 , a burner 200 and a smoke guiding device 300 .

[0031] The pot rack 100 is used to support the pot 2, and the burner 200 is surrounded by the pot rack 100. The burner 200 is used to heat the pot 2. By supporting the pot 2 by the pot rack 100, a certain space can be provided between the burner 200 and the pot 2, and the flame generated by the burner 200 can heat the pot 2 more efficiently.

[0032] The smoke guiding device 300 is arranged on the outside of the boiler frame 100 along the radial direction of the boiler frame 100 and is provided with a smoke guiding channel 310. The smoke guiding channel 310 has a zigzag section 311. The zigzag section 311 is higher than the upper surface of the boiler frame 100 and is used to guide the smoke generated by the burner 200 to flow upward. The extension dimension of the zigzag section 311 is greater than the dimension of the zigzag section 311 in the axial direction of the boiler frame 100.

[0033] Specifically, the smoke guiding device 300 and the pot 2 are spaced apart in the radial direction of the pot rack 100 to avoid interference between the smoke guiding device 300 and the pot 2 , and the pot 2 can be conveniently placed on and removed from the pot rack 100 .

[0034] The smoke escaping from between the cooker 1 and the pot 2 has heat and will move upward and move outward along the radial direction of the pot rack 100. Since the smoke guiding device 300 is arranged on the outer side of the pot rack 100 along the radial direction of the pot rack 100, the smoke guiding device 300 will block the smoke from moving outward along the radial direction of the pot rack 100. Therefore, the smoke moves upward through the gap between the smoke guiding device 300 and the pot 2, and a larger flow of smoke contacts the pot 2, thereby increasing the heat exchange between the smoke and the pot 2.

[0035] In addition, the smoke guiding channel 310 guides the flow of smoke. Since the extension size of the zigzag section 311 is larger than the axial size of the zigzag section 311 in the pot rack 100, the flow time of the smoke in the smoke guiding channel 310 is increased, thereby increasing the heat exchange time between the smoke and the pot 2, thereby improving the heat exchange amount between the smoke and the pot 2.

[0036] The axial dimension of the zigzag section 311 on the pot rack 100 refers to the distance between the highest point and the lowest point of the zigzag section 311 on the pot rack 100 axially; the extended dimension of the zigzag section 311 refers to the total length of the zigzag section 311 .

[0037] It can be seen that the stove 1 of the embodiment of the present application, by adding the smoke guiding device 300, improves the heat exchange rate between the smoke escaping from the pot rack 100 and the pot 2 and the peripheral surface of the pot 2, thereby the heating speed of the pot 2 is faster, the heating time required for the pot 2 is shortened, and the heat of the escaping smoke is effectively recovered, thereby reducing energy consumption and heat loss.

[0038] In some embodiments of the present application, Figure 1 and Figure 2 As shown, a smoke channel 110 is defined between the upper surface of the pot rack 100 and the lower surface of the pot 2. In the axial direction of the pot rack 100, the smoke guiding device 300 corresponds to the position of the smoke channel 110, and is used to guide the smoke escaping from the smoke channel 110 to flow toward the smoke guiding channel 310.

[0039] In this way, the smoke generated by the burner 200 is discharged to the outside of the pot rack 100 through the smoke channel 110, and the position of the smoke guiding device 300 is aligned with the smoke channel 110. After the smoke escapes, it is directly blocked by the smoke guiding device 300 and will not continue to flow radially outward along the pot rack 2. After the smoke escapes, it can enter the smoke guiding channel 310 of the smoke guiding device 300 more quickly to reduce the heat damage of the smoke before entering the smoke guiding channel 310, and increase the smoke flow rate entering the smoke guiding channel 310, recover more smoke heat, further increase the heating rate of the pot 2, and shorten the heating time required for the pot 2.

[0040] In some embodiments of the present application, the smoke guide device 300 extends along the circumference of the pot rack 100. That is, the smoke guide device 300 can be configured as an arc, so that the shape of the smoke guide device 300 is more compatible with the shape of the pot rack 100. Compared with configuring the smoke guide device 300 as a plane, under the same area, the distance between the arc-shaped smoke guide device 300 and the pot rack 100 is smaller, which can improve the efficiency of the smoke guide device 300 in guiding smoke, avoid disorderly diffusion of smoke, and improve the heat utilization rate of smoke.

[0041] In some embodiments of the present application, Figure 1 and Figure 2 As shown, there are multiple smoke guiding devices 300, and the multiple smoke guiding devices 300 are evenly and spacedly arranged along the circumference of the pot rack 100. For example, the smoke guiding devices 300 are located on opposite sides of the pot rack 100 in the radial direction.

[0042] By increasing the number of smoke guiding devices 300, the overall amount of smoke guided by the smoke guiding devices 300 can be increased, the escaped smoke can be utilized on a larger scale, and the heat utilization rate of the smoke can be improved. Moreover, since the plurality of smoke guiding devices 300 are evenly arranged along the pot rack 100, the smoke around the pot rack 100 can be effectively guided, avoiding the situation where the plurality of smoke guiding devices 300 are too concentrated, resulting in the effective utilization of the smoke in one area of ​​the pot rack 100 and the disorderly diffusion of the smoke on the other side.

[0043] In addition, since the plurality of smoke guiding devices 300 are spaced apart along the circumference of the pot rack 100 , the user can contact the pot 2 through the spacers to take out and place the pot 2 .

[0044] In some embodiments of the present application, the height of the smoke guiding device 300 may be lower than the upper end of the pot 2 , so that the user can contact the upper end of the pot 2 to achieve the removal and placement of the pot 2 .

[0045] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the lower surface of the smoke guiding device 300 is not higher than the outer periphery of the upper surface of the pot rack 100. In this way, in the axial direction of the pot rack 100, the smoke channel 110 is completely covered by the smoke guiding device 300, and the smoke escaping from the smoke channel 110 can be completely blocked by the smoke guiding device 300, further increasing the flow rate of smoke flowing into the smoke guiding channel 310, and further increasing the heat of the recovered smoke.

[0046] In some embodiments of the present application, Figure 4 and Figure 5 As shown, the zigzag section 311 is constructed as a spiral structure. In this way, the length of the flow path of the smoke can be increased, thereby increasing the heat exchange time between the smoke and the cookware 2, and the heat of the smoke can be transferred to the cookware 2 more to improve the heat utilization rate of the smoke.

[0047] For example, the portion of the smoke guiding channel 310 below the lower surface of the cookware 2 can be a straight segment, and the straight segment extends along the axial direction of the cookware 2, so that the time spent by the smoke in the portion of the smoke guiding channel 310 below the lower surface of the cookware 2 is shorter, thereby reducing the heat consumption of the smoke in the portion of the smoke guiding channel 310 below the lower surface of the cookware 2, thereby increasing the heat exchange between the smoke and the cookware 2, and improving the heat utilization rate of the smoke.

[0048] In some embodiments of the present application, Figure 4-Figure 5As shown, the smoke guiding device 300 is provided with a plurality of smoke guiding channels 310, and the plurality of smoke guiding channels 310 are arranged at intervals along the circumference of the pot rack 100. By increasing the number of the smoke guiding channels 310, the smoke guiding device 300 can guide a larger flow of smoke, thereby increasing the utilization amount of the escaping smoke and improving the heat utilization rate of the smoke.

[0049] In some embodiments of the present application, Figure 5 As shown, the smoke guiding device 300 has an inner side surface and an outer side surface that are relatively arranged in the radial direction of the pot rack 100, the inner side surface is closer to the pot 2 than the outer side surface, and the smoke guiding channel 310 is arranged in the smoke guiding device 300, the upper end of the smoke guiding channel 310 passes through the inner side surface and / or the upper side surface of the smoke guiding device 300, and the lower end of the smoke guiding channel 310 passes through the inner side surface of the smoke guiding device 300.

[0050] In this way, the smoke guiding channel 310 is independently constituted by the smoke guiding device 300 , and the structure of the smoke guiding channel 310 is more stable, and can effectively control the flow speed and diffusion direction of the smoke, thereby ensuring sufficient heat exchange time with the cookware 2 .

[0051] In other embodiments of the present application, Figure 4 As shown, the smoke guiding device 300 has an inner side surface and an outer side surface that are relatively arranged in the radial direction of the pot rack 100. The inner side surface is closer to the pot 2 than the outer side surface. The smoke guiding channel 310 is arranged on the inner side surface of the smoke guiding device 300. The inner side surface of the smoke guiding device 300 and the outer peripheral surface of the pot 2 jointly define a diffusion space for the smoke so that the smoke flows along the smoke guiding channel 310.

[0052] That is to say, the inner side surface of the smoke guiding device 300 is provided with a groove-shaped channel structure or a trench-shaped channel structure, and the channel structure constitutes a part of the smoke guiding channel 310 .

[0053] In this way, the smoke guiding channel 310 is defined by the inner side surface of the smoke guiding device and the cooker 2, which can reduce the volume of the smoke guiding device 300, and the escaping smoke is in direct contact with the cooker 2 for heat exchange, which can increase the heat exchange efficiency between the smoke and the cooker 2, thereby improving the heat utilization rate of the smoke.

[0054] In some embodiments of the present application, Figure 1As shown, the pot rack 100 and the smoke guide device 300 are constructed as an integrated structure, so that the pot rack 100 and the smoke guide device 300 can be processed and formed as a whole, which reduces the production steps, improves the production efficiency, increases the connection strength between the pot rack 100 and the smoke guide device 300, and reduces the probability of separation between the pot rack 100 and the smoke guide device 300. Moreover, the pot rack 100 and the smoke guide device 300 can be installed and disassembled together, which reduces the disassembly steps and improves the assembly and disassembly efficiency.

[0055] In other embodiments of the present application, the pot rack 100 and the smoke guide device 300 are detachably connected. In this way, the pot rack 100 and the smoke guide device 300 can be installed and removed separately. When one of the pot rack 100 and the smoke guide device 300 is damaged, there is no need to repair or replace the other, which reduces the maintenance cost, makes transportation and storage more convenient, and occupies less space. In this case, the smoke guide device 300 is an optional part, and the user can select it according to his own needs, which expands the applicability of the stove 1.

[0056] In some embodiments of the present application, Figure 2 As shown, the cooker 1 further includes a panel 400 , and the pot support 100 , the burner 200 and the smoke guiding device 300 are arranged on the upper surface of the panel 400 , and the smoke guiding device 300 is movable relative to the panel 400 .

[0057] For example, the panel 400 may be provided with a slide rail (not shown in the figure), and the smoke guiding device 300 may be provided with a slider (not shown in the figure), which may be slidably disposed in the slide rail. The smoke guiding device 300 may slide manually relative to the panel 400, or the smoke guiding device 300 may slide automatically relative to the panel 400, and the smoke guiding device 300 may be driven to slide relative to the panel 400 by providing a driving device such as a motor or a hydraulic driver (not shown in the figure).

[0058] By setting the panel 400, the relative positions of the pot rack 100, the burner 200 and the smoke guide device 300 can be fixed, and since the smoke guide device 300 is movable relative to the panel 400, when pots 2 of different sizes are placed on the cooker 1, the position of the smoke guide device 300 relative to the panel 400 can be adjusted to adjust the position of the smoke guide device 300 relative to the pot 2. On the one hand, the pot 2 and the smoke guide device 300 will not be too close to avoid interference between the pot 2 and the smoke guide device 300. On the other hand, the smoke guide device 300 will not be too far from the pot 2, so that the smoke guide device 300 can absorb more escaping smoke and improve the smoke utilization rate.
