Description

Technical Field

[0001] The present invention relates to the field of kitchen appliances, and in particular to an integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good range hood effect, energy saving, low consumption and environmental protection.

[0003] In the current integrated stove oil fume absorption structure, the air duct in the integrated stove is connected to the smoke exhaust duct. After the integrated stove is used for a long time, the connection between the air duct and the smoke exhaust duct will become loose, resulting in a gap. In the integrated stove, the volute of the integrated stove is connected to the air duct, and the air inlet of the volute will exhaust the smoke into the air duct from the air outlet after drawing smoke, and the smoke will be discharged through the air duct and the smoke exhaust duct. During the smoking process of the volute, a certain amount of oil will be drawn in at the same time. After the volute draws in the oil fume, the oil in the oil fume will condense through structures such as filters, so that the oil drips into the air duct. Since air circulates in the air duct and the smoke exhaust duct, the condensed oil will flow in the air duct. When the oil flows to the connection between the air duct and the smoke exhaust duct, it will flow out at the gap that appears at the connection, thereby causing oil leakage, which will dirty the inside of the integrated stove or the kitchen floor. Summary of the invention

[0004] The problem solved by the invention is how to collect the oil leakage at the connection between the air duct and the smoke exhaust pipe.

[0005] In order to solve the above problems, the present invention provides an integrated stove, including an air duct and a volute, the air duct is connected to the air outlet of the volute, the air duct outlet of the air duct is connected to the smoke exhaust pipe, and an oil storage mechanism is arranged below the connection between the air duct outlet and the smoke exhaust pipe. The oil storage mechanism is used to collect and store oil stains, thereby preventing the oil stains from scattering and causing the cleanliness of the integrated stove or kitchen to decrease.

[0006] Optionally, the oil storage mechanism includes an oil guiding structure and an oil collecting box, and the oil guiding structure is suitable for guiding the oil into the oil collecting box, and guiding the flow direction of the oil through the oil guiding structure to guide the oil into the oil collecting box for storage, so as to facilitate the installation of the oil collecting box in a specific location and facilitate the collection of oil stains.

[0007] Optionally, the oil guide structure is an oil guide plate, which includes a high portion and a low portion. The oil guide plate is inclined at an angle to the horizontal plane, and the inclined setting is gradually approaching the horizontal plane from the high portion to the low portion. Through the inclination and the effect of gravity, the flow of oil is guided to facilitate the collection of oil.

[0008] Optionally, the high-position portion is located directly below the connection between the air duct outlet and the smoke exhaust pipe, and the low-position portion is located directly above the oil collecting box to prevent oil stains from clogging the oil collecting box.

[0009] Optionally, the oil collecting box includes a box body and a first oil leakage hole arranged on the box body, and a second oil leakage hole is arranged on the low-position part. The second oil leakage hole is located directly above the first oil leakage hole, so as to facilitate the condensation of oil into oil droplets. The oil passes through the first oil leakage hole in the form of oil droplets and enters the box body of the oil collecting box. At the same time, due to the effect of gravity, the oil droplets are not easy to block the first oil leakage hole, thereby providing better oil guiding and oil collecting effects.

[0010] Optionally, the integrated stove further comprises an air outlet seat, and the air duct air outlet and the smoke exhaust pipe are fixedly connected via the air outlet seat, so that the air duct and the smoke exhaust pipe can be conveniently connected and communicated, and at the same time, can be better fixed on the integrated stove.

[0011] Optionally, a third oil leakage hole is provided on the air outlet seat, and the third oil leakage hole is located between the high position portion and the connection between the air duct outlet and the smoke exhaust pipe, so as to facilitate the dripping of oil and prevent the oil from scattering everywhere.

[0012] Optionally, a fourth oil leakage hole is provided in the air duct, and the fourth oil leakage hole is located above the oil collecting box, and can guide the oil into the oil collecting box, so as to reduce the frequency of cleaning the oil stains in the air duct.

[0013] Optionally, the fourth oil leakage hole is located directly above the second oil leakage hole, which can reduce the provision of the oil collecting box. The oil stains generated in multiple places of the integrated stove can be collected by one oil collecting box, thereby reducing production costs.

[0014] Optionally, the air duct is tilted at an angle to the horizontal plane, and the tilted setting is arranged so as to gradually approach the horizontal plane from the air outlet of the air duct to the fourth oil leakage hole, thereby reducing oil leakage at the connection.

[0015] Optionally, the inner wall of the air duct and / or the inner wall of the smoke exhaust pipe is a streamlined structure, so that when the integrated stove exhausts smoke through the air duct and the smoke exhaust pipe, the streamlined pipe cavity can better reduce the wind resistance of the pipe smoke exhaust, thereby further reducing wind noise.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] A brief explanation is given of the orientations involved in the following specific implementation methods: the directions or positional relationships indicated by "front", "rear", "up", "down", "left" and "right" mentioned in the embodiments refer to the orientations or positional relationships shown in the drawings, and these orientations are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0026] Reference Figure 1-5 As shown, the present invention proposes an integrated stove, including an air duct 2 and a volute 1, the air duct 2 is connected to the air outlet 101 of the volute 1, the air duct outlet 201 of the air duct 2 is connected to the smoke exhaust pipe 3, and an oil storage mechanism 4 is arranged below the connection between the air duct outlet 201 and the smoke exhaust pipe 3.

[0027] In the related art, the air duct outlet 201 of the air duct 2 is connected to the smoke exhaust pipe 3. When installing the integrated stove, the air duct 2 of the integrated stove is usually detachable from the smoke exhaust pipe 3 to facilitate the transportation of the integrated stove or the lengthening of the smoke exhaust pipe 3. In this case, it cannot be guaranteed that the connection between the air duct 2 and the smoke exhaust pipe 3 is always in a sealed state. After the integrated stove is used for a long time, the air duct 2 and the smoke exhaust pipe 3 will become loose, resulting in a gap. At the same time, in the integrated stove, the smoke extracted by the volute 1 during the smoking process is usually in the form of oil smoke, and the smoke is accompanied by oil stains. After the volute 1 draws the oil smoke in, the oil in the oil smoke will be condensed through structures such as filters. As a result, oil will drip into the air duct 2, and since air circulates in the air duct 2 and the smoke exhaust duct 3, condensed oil will flow in the air duct 2, and when the oil flows to the connection between the air duct 2 and the smoke exhaust duct 3, it will flow out at the gap at the connection, thereby causing oil leakage, which will dirty the inside of the integrated stove or the kitchen floor. In this case, although it is a feasible solution to set a step or baffle at the connection between the air duct 2 and the smoke exhaust duct 3 to prevent the oil from flowing to the smoke exhaust duct 3 and thus reduce oil leakage, the air circulating in the air duct 2 and the smoke exhaust duct 3 will hit the baffle or step during the smoke exhaust process, which will generate a lot of noise.

[0028] In the present invention, an oil storage mechanism 4 is provided below the connection between the air duct outlet 201 of the air duct 2 and the smoke exhaust pipe 3. The oil storage mechanism 4 is provided to collect and store oil stains, so as to prevent the oil stains from scattering and causing the cleanliness of the integrated stove or kitchen to decrease. Compared with setting steps or baffles and other structures to block the oil stains, the oil storage mechanism 4 directly stores the oil stains, which can prevent negative problems such as noise and is beneficial to the discharge of oil stains in the air duct 2. When the integrated stove is running, the smoke exhaust effect will not be poor due to excessive oil stains accumulated in the air duct 2. Therefore, the cleaning frequency of the air duct 2 can be reduced.

[0029] In an optional embodiment of the present invention, the oil storage mechanism 4 includes an oil guiding structure and an oil collecting box 402, and the oil guiding structure is suitable for guiding oil into the oil collecting box 402. In this embodiment, when the integrated stove is running, oil drips from the connection between the air duct 2 and the smoke exhaust pipe 3, and the flow direction of the oil is guided by the oil guiding structure to guide it into the oil collecting box 402 for storage, so as to facilitate the installation of the oil collecting box 402 in a specific position and facilitate the collection of oil.

[0030] In an optional embodiment of the present invention, the oil guide structure is an oil guide plate 401, and the oil guide plate 401 includes a high portion 4011 and a low portion 4012. The oil guide plate 401 is inclined at an angle to the horizontal plane, and the inclined setting is gradually approaching the horizontal plane from the high portion 4011 to the low portion 4012.

[0031] Reference Figure 1-3 As shown, the oil guide structure in this embodiment is an oil guide plate 401, through which the oil is guided and flows into the oil collecting box 402, wherein the oil guide plate 401 is a flat structure, inclined at an angle to the horizontal plane, and its specific inclination is gradually approaching the horizontal plane from the high part 4011 to the low part 4012, thereby guiding the flow of oil through the inclination and the action of gravity, so that the oil flows into the oil collecting box 402. In the present invention, the use of the oil guide plate 401 as the oil guide structure is only a preferred choice of the present invention, so that the oil leakage that may exist at the connection between the air duct outlet 201 of the air duct 2 and the smoke exhaust pipe 3 can be guided into the oil collecting box 402 and stored through a simple structure, so as not to greatly increase the production cost of the integrated stove, wherein the oil can be guided by the action of gravity through an oil guide pipe, an oil guide strip, etc., or by a conveyor belt or a transmission structure, and the purpose of the present invention can also be achieved.

[0032] In this embodiment, the inclination angle is 2°, which can make the oil flow on the oil guide plate 401 based on gravity on the one hand, and will not occupy too much bottom space of the integrated stove on the other hand.

[0033] The high-position portion 4011 is located directly below the connection between the air duct outlet 201 and the smoke exhaust pipe 3 , and the low-position portion 4012 is located directly above the oil collecting box 402 .

[0034] Reference Figure 1 As shown, in this embodiment, the high portion 4011 is located directly below the connection between the air duct outlet 201 and the smoke exhaust pipe 3, and when the oil guide plate 401 is tilted, the oil flows from the high portion 4011 to the low portion 4012, thereby introducing the oil into the oil collecting box 402, wherein the low portion 4012 is located directly above the oil collecting box 402, and when the oil flows, it drips from the low portion 4012 into the oil collecting box 402.

[0035] Under normal circumstances, the amount of oil dripping from the connection between the air duct 2 and the smoke exhaust pipe 3 is small. At the same time, when the flow is guided by the oil guide plate 401, the oil moves and causes the oil to be more dispersed on the oil guide plate 401. If the oil guide plate 401 is directly connected to the oil collecting box 402 for oil storage, the oil may solidify during the flow, causing the connection channel between the oil guide plate 401 and the oil collecting box 402 to be blocked, which is not conducive to oil storage.

[0036] Therefore, in the present embodiment, by allowing the oil to drip from the lower portion 4012 into the oil collecting box 402, the oil will drip from the lower portion 4012 into the oil collecting box 402 only after the amount of oil flowing on the oil guide plate 401 reaches a certain level. Compared with the lower portion 4012 being directly connected to the oil collecting box 402, the oil is less likely to clog the connection between the lower portion 4012 and the oil collecting box 402.

[0037] Optionally, the oil collecting box 402 includes a box body 4021 and a first oil leakage hole 4022 arranged on the box body 4021 , and a second oil leakage hole 4112 is arranged on the low-position portion 4012 , and the second oil leakage hole 4112 is located directly above the first oil leakage hole 4022 .

[0038] Reference Figure 3-5 As shown, in the present embodiment, a second oil leakage hole 4112 is provided on the low-position portion 4012. When the amount of oil flowing out from the connection between the air duct 2 and the smoke exhaust pipe 3 is small, the second oil leakage hole 4112 can better condense the oil into oil droplets. Correspondingly, a first oil leakage hole 4022 is provided on the oil collecting box 402. The first oil leakage hole 4022 is located directly below the second oil leakage hole 4112. Therefore, after the oil on the oil guide plate 401 is condensed into oil droplets, the oil passes through the first oil leakage hole 4022 in the form of oil droplets and enters the box body 4021 of the oil collecting box 402. At the same time, due to the effect of gravity, the oil droplets are not easy to block the first oil leakage hole 4022, thereby providing better oil guiding and collecting effects.

[0039] Among them, in order to enable the present invention to obtain a better oil collection effect, the second oil leakage hole 4112 is located directly above the first oil leakage hole 4022, which is a preferred solution adopted by the present invention. Among them, the second oil leakage hole 4112 is located above the first oil leakage hole 4022, but there is a certain deviation between the hole axis of the second oil leakage hole 4112 and the first oil leakage hole 4022, and the technical solution of the present invention can also be realized.

[0040] In an optional embodiment of the present invention, the integrated stove further includes an air outlet seat 6, and the air duct air outlet 201 is fixedly connected to the smoke exhaust pipe 3 through the air outlet seat 6. Figure 1 , 2 As shown in FIG. 4 , in the present embodiment, the air duct outlet 201 of the air duct 2 is connected to the smoke exhaust pipe 3 via the air outlet seat 6. By setting the air outlet seat 6, the air duct 2 and the smoke exhaust pipe 3 can be conveniently connected and communicated, and can be better fixed on the integrated stove.

[0041] As shown in the figure, the air outlet seat 6 includes a frame with an opening formed in the frame, and the air duct 2 and the smoke exhaust pipe 3 are respectively connected to both sides of the opening to form a fixed connection and communication.

[0042] Among them, the air outlet seat 6 can be fixedly connected to the air duct 2 and the smoke exhaust pipe 3 by bolts. After the air outlet seat 6 is connected and fixed to the air duct 2 and the smoke exhaust pipe 3, the air outlet seat 6 can be connected and fixed to the integrated stove by bolts, so that the connection between the air duct 2 and the smoke exhaust pipe 3 is more stable and convenient for installation and fixation, and at the same time, the vibration generated when the air flows in the air duct 2 and the smoke exhaust pipe 3 is prevented, thereby reducing noise.

[0043] In an optional embodiment of the present invention, a third oil leakage hole 601 is provided on the air outlet seat 6, and the third oil leakage hole 601 is located between the high position portion 4011 and the connection between the air duct air outlet 201 and the smoke exhaust pipe 3, wherein Figure 1 and 2 As shown, the third oil leakage hole 601 is located between the high position part 4011 and the connection between the air duct outlet 201 and the smoke exhaust pipe 3. Specifically, as shown in the figure, the third oil leakage hole 601 is located on the air outlet seat 6, and is located below the connection between the air duct outlet 201 and the smoke exhaust pipe 3, preferably directly below the connection. On the one hand, the smoke exhaust pipe 3 and the air duct 2 can be connected and fixed through the air outlet seat 6. At the same time, the third oil leakage hole 601 is set on the air outlet seat 6 below the connection corresponding to the connection so that the oil can flow into the oil guide plate 401, so as to guide the oil so that the oil is in a reasonable area during the flow and dripping process, and the oil will not be scattered everywhere due to the flow of air when the volute 1 is running.

[0044] In an optional embodiment of the present invention, a fourth oil leakage hole 202 is provided in the air duct 2, and the fourth oil leakage hole 202 is located above the oil collecting box 402, and is suitable for introducing oil into the oil collecting box 402. Figure 4 and 5 As shown, in the related art, after the oil flows into the air duct 2 from the volute 1, it will accumulate in the air duct 2. If the air duct 2 is not cleaned for a long time, excessive accumulation of oil will lead to poor smoke exhaust effect. Therefore, in the present invention, a fourth oil leakage hole 202 is provided in the air duct 2. The fourth oil leakage hole 202 can drain the oil from the air duct 2 and introduce it into the oil collecting box 402, thereby reducing the frequency of cleaning the oil in the air duct 2.

[0045] Among them, in an optional embodiment of the present invention, the fourth oil leakage hole 202 is located directly above the second oil leakage hole 4112. When the fourth oil leakage hole 202 discharges the oil in the air duct 2, the oil passes through the second oil leakage hole 4112 on the low-position part 4012 and drips into the first oil leakage hole 4022, thereby entering the oil collecting box 402 for oil collection. The structural design is simple and reasonable, and at the same time, the setting of the oil collecting box 402 can be reduced. The oil generated in multiple places of the integrated stove can be collected through one oil collecting box 402, thereby reducing the production cost.

[0046] In an optional embodiment of the present invention, referring to Figure 1 and 4 As shown, the air duct 2 is tilted at an angle to the horizontal plane, and the tilted arrangement is such that the air duct outlet 201 to the fourth oil leakage hole 202 gradually approaches the horizontal plane. Figure 4 , the horizontal plane is equivalent to the ground when the integrated stove described in the present invention is placed, wherein the inclination is that the air duct outlet 201 to the fourth oil leakage hole 202 gradually inclines downward and approaches the ground, so that the air duct outlet 201 is higher than the fourth oil leakage hole 202. Based on this, in the present invention, when there is oil in the air duct 2, by tilting the air duct 2, based on the effect of gravity, the oil in the air duct 2 can flow to the fourth oil leakage hole 202, so as to quickly collect the oil in the air duct 2 and improve the cleanliness of the air duct 2, thereby improving the use effect of the integrated stove and reducing the cleaning frequency of the air duct 2. At the same time, the air duct outlet 201 is at a higher point of the air duct 2. When the volute 1 is exhausting smoke, it can reduce the oil flowing to the connection between the air duct 2 and the smoke exhaust pipe 3, thereby reducing oil leakage at the connection.

[0047] In an optional embodiment of the present invention, the inner wall of the air duct 2 and / or the inner wall of the smoke exhaust pipe 3 is a streamlined structure, so that when the integrated stove exhausts smoke through the air duct 2 and the smoke exhaust pipe 3, the streamlined structure of the pipe lumen can better reduce the wind resistance of the pipe smoke exhaust, thereby further reducing wind noise. At the same time, when the air duct 2 is inclined at an angle to the horizontal plane, the inner wall of the air duct 2 with a streamlined structure can better guide the oil to the fourth oil leakage hole 202 to prevent the accumulation of oil in the air duct 2, thereby further improving the cleanliness of the air duct 2, improving the use effect of the integrated stove, and reducing the cleaning frequency.

[0048] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
