[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0042] Please refer to the following Figure 1-4 A combined stove 100 according to an embodiment of the present invention is described.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 According to an embodiment of the utility model, a combination stove 100 includes: a stove plate 10, a fan assembly 20 and an oil cup 30.

[0044] Specifically, the stove plate 10 is provided with an oil fume inlet 11 which runs through the upper surface of the stove plate 10 from top to bottom; the fan assembly 20 is arranged on the lower side of the stove plate 10 (such as Figure 2The fan assembly 20 includes a volute 21, a flow cavity is formed in the volute 21, and the flow cavity is connected to the oil fume inlet 11. The bottom of the volute 21 is provided with an oil outlet 211; the oil cup 30 is arranged on the lower side of the volute 21 (as shown in FIG. Figure 2 The lower side of the volute 21 is shown in the figure) and is connected to the oil outlet hole 211.

[0045] For example, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stove plate 10 is a horizontal plate extending in the left-right direction, the oil fume inlet 11 is arranged on the upper surface of the stove plate 10 and penetrates the stove plate 10 in the up-down direction, the fan assembly 20 is connected to the stove plate 10 through a volute 21, the volute 21 is arranged on the lower side of the stove plate 10, a flow cavity extending in the up-down direction is formed in the volute 21, an oil outlet hole 211 penetrating the volute 21 along the thickness direction of the volute 21 is provided at the bottom of the volute 21, and the flow cavity connects the oil outlet hole 211 and the oil fume inlet 11.

[0046] When the combination stove 100 is in operation, the food cooked on the stove plate 10 will produce oil smoke. At this time, the fan assembly 20 generates negative pressure when in operation. The negative pressure drives the oil smoke into the volute 21 through the oil smoke inlet 11. Then the oil smoke flows from the circulation cavity of the volute 21 to the bottom of the volute 21. Finally, the oil smoke flows from the oil outlet 211 at the bottom of the volute 21 to the oil cup 30, and the oil cup 30 collects the oil smoke.

[0047] In the combined stove 100 of the present invention, an oil cup 30 is arranged at the bottom of the volute 21. When the fan assembly 20 is in operation, the oil smoke at the bottom of the volute 21 can flow into the oil cup 30 from the oil outlet 211. Compared with the solution in the prior art that the oil cup 30 is directly arranged between the oil smoke inlet 11 and the fan assembly 20, resulting in the oil smoke at the bottom of the volute 21 being unable to be collected into the oil cup 30, the oil cup 30 of the present application is arranged at the bottom of the volute 21 of the fan assembly 20, and can collect the oil smoke at the bottom of the fan assembly 20, thereby improving the oil smoke collection capacity of the combined stove 100. At the same time, it can prevent the oil smoke at the bottom of the fan assembly 20 from accumulating for a long time and emitting odor, thereby effectively improving the user experience.

[0048] According to the combination stove 100 of the embodiment of the utility model, an oil cup 30 is arranged at the bottom of the volute 21, which can collect the oil smoke at the bottom of the fan assembly 20, thereby improving the oil smoke collection capacity of the combination stove 100. At the same time, it can prevent the oil smoke at the bottom of the fan assembly 20 from accumulating for a long time and emitting odor, thereby effectively improving the user experience.

[0049] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3The bottom wall of the volute 21 extends obliquely, and the oil outlet 211 is set at the lowest point of the bottom wall of the volute 21. Therefore, it can be ensured that the oil smoke flowing to the bottom of the volute 21 can flow to the oil outlet 211 along the bottom wall of the volute 21, so that the oil smoke can flow into the oil cup 30, and then the ability of the combined stove 100 to collect oil smoke can be guaranteed. At the same time, it can effectively prevent the oil smoke from gathering at the bottom of the volute 21, so as to prevent the oil smoke at the bottom of the volute 21 from accumulating for a long time and generating odor, so as to further ensure the use experience.

[0050] According to some optional embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3 , the number of oil outlet holes 211 is multiple, that is, the number of oil outlet holes 211 can be two, three or four or more, and the multiple oil outlet holes 211 are arranged at intervals. Therefore, the multiple oil outlet holes 211 can increase the flow rate of oil smoke into the oil cup 30, thereby increasing the flow speed of oil smoke into the oil cup 30, saving the time for oil smoke to flow into the oil cup 30, and thus effectively preventing the oil smoke from adhering to the bottom wall of the volute 21. For example, Figure 1 , Figure 2 and Figure 3 As shown, three oil outlet holes 211 are provided, and the three oil outlet holes 211 are arranged at intervals along the left-right direction.

[0051] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 and Figure 3 The fan assembly 20 further includes: a wheel cover 22 and an impeller 23. A flow port is provided at the top of the wheel cover 22, and the flow port is opposite to and communicates with the oil fume inlet 11, and an oil leakage hole 2222 is provided at the bottom wall of the wheel cover 22, and the oil leakage hole 2222 is communicated with the flow cavity; the impeller 23 is arranged in the wheel cover 22.

[0052] In this way, the oil leakage hole 2222 is connected with the oil fume inlet 11 through the circulation port, so the oil fume can flow to the circulation cavity through the oil fume inlet 11, the circulation port and the oil leakage hole 2222 in sequence, thereby ensuring that the oil fume can flow into the oil cup 30. At the same time, the oil fume inlet 11 and the circulation port are directly opposite to each other up and down, thereby reducing the distance that the oil fume flows from the oil fume inlet 11 to the circulation cavity, saving the oil fume flow time.

[0053] For example, Figure 1 , Figure 2 and Figure 3 As shown, the wheel cover 22 is disposed in the volute 21 , a circular flow opening is formed on the top of the wheel cover 22 , the flow opening is directly opposite to the oil fume inlet 11 in the up and down direction, and the impeller 23 is disposed in the wheel cover 22 .

[0054] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2The bottom wall of the wheel cover 22 extends obliquely, and the oil leakage hole 2222 is set at the lowest point of the bottom wall of the wheel cover 22. Therefore, it can be ensured that the oil smoke flowing to the bottom wall of the wheel cover 22 can flow to the oil leakage hole 2222 along the bottom wall of the volute 21, so that the oil smoke can flow into the flow cavity, and then the ability of the combined stove 100 to collect oil smoke can be guaranteed. At the same time, it can effectively prevent the oil smoke from gathering on the bottom wall of the wheel cover 22, so as to prevent the oil smoke on the bottom wall of the wheel cover 22 from accumulating for a long time and generating odor.

[0055] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 The bottom wall of the wheel cover 22 is provided with a groove 2223 that is sunken downwards, and the oil leakage hole 2222 is provided in the groove 2223 and penetrates the bottom wall of the groove 2223. Therefore, the groove 2223 provides a setting position for the oil leakage hole 2222, so that the setting of the oil leakage hole 2222 can be facilitated. At the same time, the groove 2223 is sunken downwards, which can first guide the oil smoke on the bottom wall of the wheel cover 22 to flow to the groove 2223, and then flow to the oil leakage hole 2222, so that the flow speed of the oil smoke can be increased again, saving the flow time.

[0056] For example, Figure 1 and Figure 2 As shown, the groove 2223 is formed by being recessed downward from the bottom wall of the wheel cover 22, and an oil leakage hole 2222 is arranged in the groove 2223, and the oil leakage hole 2222 penetrates the bottom wall of the groove 2223 in the up and down directions.

[0057] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The number of the oil leakage holes 2222 is multiple, that is, the number of the oil leakage holes 2222 can be two, three or four or more, and the multiple oil leakage holes 2222 are arranged on the radial outside of the impeller 23 and are arranged at intervals along the circumference of the impeller 23.

[0058] In this way, the plurality of oil leakage holes 2222 can increase the flow rate of the oil smoke into the circulation cavity, thereby increasing the flow speed of the oil smoke into the circulation cavity, saving the time for the oil smoke to flow into the oil cup 30, and thus effectively preventing the oil smoke from adhering to the bottom wall of the wheel cover 22. In addition, the oil leakage holes 2222 are arranged radially outside the impeller 23, and when the impeller 23 rotates, the centrifugal force can be provided to the oil smoke to move away from the impeller 23, thereby further accelerating the flow speed of the oil smoke. At the same time, this arrangement is reasonable and can ensure the normal flow of the oil smoke.

[0059] For example, Figure 1 and Figure 2As shown, a plurality of grooves 2223 are arranged on the radial outer side of the impeller 23 , and the plurality of grooves 2223 are arranged at intervals around the circumference of the impeller 23 , and an oil leakage hole 2222 is provided in each groove 2223 , so that the plurality of oil leakage holes 2222 are all arranged on the radial outer side of the impeller 23 .

[0060] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The wheel cover 22 includes: a first plate 221, a second plate 222 and a side plate 223. The first plate 221 is an annular plate and defines a flow opening; the second plate 222 is an annular plate and is arranged on the lower side of the first plate 221 (such as Figure 2 The oil leakage hole 2222 is formed in the second plate 222; the side plate 223 is arranged between the first plate 221 and the second plate 222 and extends in the circumferential direction of the impeller 23 into an annular cylindrical shape, and the upper end of the side plate 223 (as shown in FIG. Figure 2 The upper end of the side plate 223 shown in FIG. 2 is connected to the radial outer periphery of the first plate 221, and the lower end of the side plate 223 (as shown in FIG. Figure 2 The lower end of the side plate 223 shown is connected to the radial outer periphery of the second plate 222.

[0061] In this way, the first plate 221 defines a flow port, which can facilitate the oil smoke entering the oil smoke inlet 11 to flow into the fan assembly 20 through the flow port. The second plate 222 is provided with an oil leakage hole 2222. Under the action of the fan assembly 20, the oil smoke can flow from the flow port of the first plate 221 to the oil leakage hole 2222 of the second plate 222. At the same time, the second plate 222 is arranged on the lower side of the first plate 221. Under the action of gravity, the flow speed of the oil smoke can be further increased, thereby preventing the oil smoke from adhering to the fan assembly 20. In addition, the side plate 223, the first plate 221 and the second plate 222 define the arrangement space of the impeller 23, thereby facilitating the arrangement of the impeller 23. At the same time, the impeller 23 can be protected in the wheel cover 22, thereby preventing the impeller 23 from colliding with other structures.

[0062] For example, Figure 1 and Figure 2 As shown, the first plate 221 is a circular plate, and a flow port is provided at the center position of the first plate 221 and penetrates the first plate 221 in the up-down direction. The second plate 222 is provided on the lower side of the first plate 221. The second plate 222 is a circular plate, and an oil leakage hole 2222 is formed on the second plate 222 and penetrates the second plate 222 in the up-down direction. The side plate 223 is arranged vertically, and the upper end of the side plate 223 is connected to the outer peripheral edge of the first plate 221, and the lower end of the side plate 223 is connected to the outer peripheral edge of the second plate 222.

[0063] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2The radial inner edge of the second plate 222 is provided with a flange 2221 that is inclined upward and faces the central axis of the impeller 23. Therefore, the oil smoke flowing from the first plate 221 to the second plate 222 can be blocked by the flange 2221 to ensure that the oil smoke can flow along the second plate 222 to the oil leakage hole 2222. At the same time, the flange 2221 extends upward and can boost the oil smoke flowing to the flange 2221, further increasing the flow speed of the oil smoke.

[0064] For example, Figure 1 and Figure 2 As shown, a radial inner edge of the second plate 222 is provided with an annular flange 2221 , and the flange 2221 extends upwardly and obliquely toward the central axis of the impeller 23 .

[0065] According to some embodiments of the present invention, referring to Figure 2 The impeller 23 includes: a plurality of blades 231 and a wheel disc 232, that is, the impeller 23 may include two, three or four or more blades 231. The plurality of blades 231 are vertically arranged and arranged at intervals around the central axis of the impeller 23; the wheel disc 232 is connected to the plurality of blades 231, and in the radially outward direction of the impeller 23, at least part of the wheel disc 232 extends downwardly in an inclined manner, that is, part of the wheel disc 232 may extend downwardly in an inclined manner, or the entire wheel disc 232 may extend downwardly in an inclined manner, and the radial outer peripheral edge of the wheel disc 232 exceeds the radial inner peripheral edge of the second plate 222.

[0066] Thus, when the blades 231 rotate, the blades 231 can push the air to flow in the axial direction. The provision of multiple blades 231 can speed up the air flow speed, thereby ensuring the speed at which the combined stove 100 absorbs the oil smoke. At the same time, the wheel disc 232 can drive the multiple blades 231 to rotate, thereby ensuring the normal operation of the impeller 23. In addition, in the radially outward direction of the impeller 23, at least part of the wheel disc 232 extends downwardly and tiltedly. When the oil smoke flows onto the wheel disc 232, the oil smoke can flow downwardly to the second plate 222 through the wheel disc 232, thereby preventing the oil smoke from remaining on the wheel disc 232. Furthermore, the outer circumference of the wheel disc 232 exceeds the inner circumference of the second plate 222, thereby ensuring that the oil smoke flowing into the wheel disc 232 can flow along the wheel disc 232 to the second plate 222, thereby ensuring that the oil smoke can flow from the wheel disc 232 to the oil leakage hole 2222.

[0067] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2The wheel disc 232 includes: an annular plate portion 2321 and a conical plate portion 2322. The annular plate portion 2321 is annular and is connected to a plurality of blades 231. That is, the annular plate portion 2321 can be connected to two, three, or four or more blades 231. The conical plate portion 2322 is connected to the radial inner side of the annular plate portion 2321. In the radial inward direction of the impeller 23, the conical plate portion 2322 extends upwardly and obliquely. A plurality of vertical directions (such as vertical directions) are formed on the conical plate portion 2322. Figure 2 In other words, the cone plate portion 2322 is provided with two, three, or four or more through holes 2323.

[0068] In this way, the ring plate portion 2321 is connected to the plurality of blades 231, and the ring plate portion 2321 can connect the plurality of blades 231 into a whole, and when the wheel disc 232 rotates, the plurality of blades 231 can be driven to rotate synchronously, and at the same time, the cone plate portion 2322 is connected to the radial inner side of the ring plate portion 2321, which will not affect the connection between the ring plate portion 2321 and the blades 231, thereby facilitating the connection between the ring plate portion 2321 and the blades 231. Furthermore, the cone plate portion 2322 is provided with a through hole 2323, and the oil smoke can directly flow to the bottom of the volute 21 through the through hole 2323, thereby increasing the flow path of the oil smoke and ensuring that the oil smoke can quickly flow to the bottom wall of the volute 21.

[0069] For example, Figure 1 and Figure 2 As shown, the ring plate portion 2321 is a circular ring plate, the blades 231 are connected to the radial outer circumference of the ring plate portion 2321, and the multiple blades 231 are arranged at intervals along the circumference of the ring plate portion 2321. The ring plate portion 2321 is arranged between the first plate 221 and the second plate 222 and is close to the second plate 222. The radial outer circumference of the cone plate portion 2322 is connected to the radial inner circumference of the ring plate portion 2321. In the radial inward direction of the impeller 23, the cone plate portion 2322 extends upward at an angle. The cone plate portion 2322 is provided with a plurality of through holes 2323, and the through holes 2323 penetrate the cone plate portion 2322 in the up and down direction. The multiple through holes 2323 are arranged at intervals along the circumference of the cone plate portion 2322.

[0070] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The impeller 23 also includes a fixing plate 233, which is annular and two fixing plates 233 are respectively connected to the upper and lower ends of the plurality of blades 231 (such as Figure 2In this way, the fixing plate 233 can fix the upper and lower ends of the plurality of blades 231, thereby preventing the blades 231 from falling onto the second plate 222 after being separated from the annular plate. At the same time, the fixing plate 233 can strengthen the connection strength between the plurality of blades 231, and even if the impeller 23 rotates rapidly, the blades 231 will not be separated from the impeller 23.

[0071] Furthermore, the fixing plate 233 and the plurality of blades 231 are arranged on the radial inner side of the first plate 221 and are located between the inner circumference and the outer circumference of the second plate 222. Thus, the blades 231 are on the radial inner side of the first plate 221, which can prevent the oil smoke from flowing directly from the oil smoke inlet 11 to the blades 231, thereby preventing excessive oil smoke from adhering to the blades 231. Furthermore, when the oil smoke is adhered to the blades 231, the oil smoke can drip along the blades 231 onto the second plate 222, thereby ensuring that the oil smoke can flow to the oil leakage hole 2222 through the second plate 222.

[0072] For example, Figure 1 and Figure 2 As shown, the blades 231 are vertically arranged in the up-down direction, a fixing plate 233 is provided at the upper end of the blade 231 , a fixing plate 233 is provided at the lower end of the blade 231 , and the fixing plate 233 extends in a ring shape along the arrangement direction of the plurality of blades 231 .

[0073] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 2 The impeller 23 includes a baffle 234, which is connected to the first plate 221 and arranged on the upper side of the first plate 221 (such as Figure 2 The baffle 234 is formed in a ring shape along the circumference of the impeller 23, and the inner end edge of the baffle 234 exceeds the inner circumference of the fixing plate 233. Thus, the baffle 234 can prevent the oil smoke from the oil smoke inlet 11 from flowing directly to the first plate 221. Since the first plate 221 is close to the stove plate 10 and is difficult to clean, the use of the baffle 234 can avoid the problem of cleaning the first plate 221. At the same time, the baffle 234 can guide the oil smoke entering the fan assembly 20, so as to ensure that the oil smoke can flow to the oil leakage hole 2222 of the second plate 222.
