Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an island-style integrated air duct oil drainage structure and an island-style integrated unit. Background Technology

[0002] Island-style integrated air conditioners perfectly complement modern high-end kitchens due to their ability to maintain a clean and visually unified look, making them a standard feature. However, with prolonged use, oil and grease can accumulate in the internal air ducts, requiring regular cleaning. Failure to address this promptly can affect product performance, reducing smoke extraction efficiency and leading to a pervasive kitchen fumes, causing inconvenience and a poor user experience. To address this issue, some manufacturers have designed products with higher speeds and larger air volumes, but these still cannot effectively remove all fumes. While they may reduce grease buildup in the short term, oil accumulation will eventually return, rendering these designs only effective for short-term use. Furthermore, increased motor power raises both energy consumption and manufacturing costs, hindering large-scale adoption.

[0003] Therefore, there is an urgent need to design an integrated island unit with an oil drain structure and an integrated island unit to solve the above technical problems. Utility Model Content

[0004] One objective of this invention is to propose an oil drainage structure for an integrated island air duct, which can effectively address the problem of oil accumulation in the integrated island air duct, ensure smoke extraction performance, and improve user experience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A drain oil structure for an island-style integrated air conditioning unit is provided, comprising:

[0007] The integrated appliance casing includes a housing and a top plate covering the housing. An air vent is provided on the top plate. The air vent includes a first air vent and a second air vent that are separated from each other. The top plate also has a mounting area, which is spaced apart from the air vent. The mounting area is used to mount the stove. An oil drain port is provided at the bottom of the housing.

The air inlet is located below the installation area and communicates with the first air outlet. The outlet of the centrifugal fan's volute is connected to the filter assembly of the island unit. The filter assembly is located below the air outlet and communicates with the second air outlet.

[0009] The centrifugal fan includes an impeller and a volute. The impeller is rotatably disposed inside the volute. The volute is inclined relative to the horizontal plane. The side of the volute closer to the filter assembly is lower in the vertical direction than the side of the volute farther from the filter assembly. An oil drain hole is provided on the side of the volute closer to the filter assembly. The oil drain hole corresponds to the oil outlet in the vertical direction.

[0010] Optionally, the plane where the outlet of the volute is located is set at an angle α with the vertical direction, where 8°≤α≤12°.

[0011] Optionally, the plane where the outlet of the volute is located is set at an angle to the vertical direction, the outlet is provided with a fixing flange, the fixing flange is detachably connected to the filter assembly, and the lower end of the fixing flange in the vertical direction is inclined towards the filter assembly.

[0012] Optionally, the integrated island unit's air duct oil drainage structure further includes a connector, which includes a first connecting part and a second connecting part. The first connecting part is arranged circumferentially around the fixed flange and connected to the fixed flange. The second connecting part is arranged perpendicular to the plane where the first connecting part is located. The first connecting part is connected to the filter assembly in the radial direction of the centrifugal fan, and the second connecting part is connected to the filter assembly in the axial direction of the centrifugal fan.

[0013] Optionally, the second connecting portion includes a second upper connecting piece and a second lower connecting piece arranged axially opposite to the centrifugal fan, and the connection position of the filter assembly and the centrifugal fan is sandwiched between the second upper connecting piece and the second lower connecting piece.

[0014] Optionally, the integrated island unit's duct oil drainage structure further includes a guide component, which is disposed between the first air outlet and the air inlet, and is used to guide the oil fumes from the first air outlet to the air inlet.

[0015] Optionally, the island-style integrated air duct oil drainage structure further includes a support member, which is installed at the bottom of the housing and located on the side of the volute away from the filter assembly. The support member is used to support the volute.

[0016] Optionally, a groove is provided at the bottom of the housing, the oil drain port is located at the bottom of the groove, and the vertical projection of the oil drain hole falls on the bottom of the groove.

[0017] Optionally, the integrated island unit's air duct oil drain structure also includes an oil cup, which is detachably mounted outside the housing and is connected to the oil drain port.

[0018] Another objective of this invention is to provide an integrated island unit that can effectively address the problem of oil accumulation in the integrated island duct, ensure smoke extraction performance, and improve user experience.

[0019] To achieve this objective, the present invention adopts the following technical solution:

[0020] An island-style integrated appliance is provided, including a cooktop and the aforementioned island-style integrated appliance air duct oil drainage structure, wherein the cooktop is disposed in the installation area.

[0021] The beneficial effects of this utility model include at least the following:

[0022] This utility model provides an integrated island cooktop with an oil drainage structure, including an integrated casing and a centrifugal fan. The integrated casing includes a box and a top plate covering the box. An air vent is provided on the top plate, including a first air vent and a second air vent separated from each other. The top plate also has a mounting area, spaced apart from the air vents, for mounting the cooktop. The centrifugal fan is located within the cavity of the box and below the cooktop. The side of the centrifugal fan facing away from the bottom of the box is the air inlet, i.e., the air inlet is located below the mounting area and is connected to the first air vent. When the centrifugal fan is turned on, the fumes generated during the use of the stove can be drawn through the first air inlet to the air inlet of the centrifugal fan, and then accelerated within the centrifugal fan casing. The outlet of the centrifugal fan casing is connected to the filter assembly of the island unit. The filter assembly is located below the air inlet and is connected to the second air inlet. After being accelerated by the centrifugal fan, the fumes enter the filter assembly, and the filtered gas can then leave the casing through the second air inlet and return to the kitchen environment, thus completing the purification of the kitchen environment. The centrifugal fan includes an impeller and a volute. The impeller rotates within the volute, which is inclined relative to the horizontal plane. The side of the volute closer to the filter assembly is vertically lower than the side furthest from the filter assembly. An oil drain hole is located on the side of the volute closer to the filter assembly, vertically opposite to an oil outlet at the bottom of the housing. This allows oil droplets condensing as fumes flow within the volute to flow with the inclination of the volute to the lower oil drain hole, and then out through the oil outlet at the bottom of the housing, automatically draining accumulated oil from the duct, reducing oil buildup, preventing it from affecting the exhaust performance of the housing, and ensuring product performance. Furthermore, the centrifugal fan's inclination towards the first air outlet not only makes it nearly horizontal within the housing, reducing space occupation, but also ensures the fan's inlet faces the first air outlet, allowing for rapid extraction of fumes and improving purification efficiency.

[0023] This utility model provides an island-style integrated appliance, including a cooktop and the aforementioned island-style integrated appliance duct oil drainage structure. The cooktop is installed in the installation area. The cooktop is positioned close to the first air vent, while the second air vent is located on the side opposite the cooktop to the first air vent. This allows the fumes generated during cooktop use to be quickly drawn into the housing for filtration. The filtered and purified gas then returns to the kitchen environment through the second air vent. The island-style integrated appliance features an island-style integrated appliance duct oil drainage structure. Its centrifugal fan is tilted relative to the horizontal plane towards the first air vent. This allows the centrifugal fan to be positioned nearly horizontally within the housing, reducing its space occupation. Furthermore, the centrifugal fan's air inlet faces the first air vent, enabling rapid drawing of fumes to the inlet and improving fume purification efficiency. Simultaneously, oil droplets condensed inside the casing are allowed to roll under gravity to the oil drain hole and be discharged autonomously from the island-style integrated appliance. This effectively addresses the problem of oil accumulation in the duct within the island-style integrated appliance, preventing it from affecting the smoke extraction effect, ensuring product performance, and improving user experience.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 4As shown, this embodiment provides an integrated island cooktop with an oil drain structure, including an integrated cooktop housing and a centrifugal fan 2. The integrated cooktop housing includes a box 1 and a top plate covering the box 1. An air vent is provided on the top plate, including a first air vent and a second air vent separated from each other. The top plate also has a mounting area, which is spaced apart from the air vents. The mounting area is used to mount the cooktop 100. The centrifugal fan 2 is disposed within the cavity 10 of the box 1 and located below the cooktop 100. The side of the centrifugal fan 2 facing away from the bottom 11 of the box 1 is the air inlet, i.e., the air inlet is located below the mounting area and is connected to the first air vent. When the centrifugal fan 2 is turned on, the oil fumes generated by the stove 100 during use can be drawn through the first air vent to the air inlet of the centrifugal fan 2, and then accelerated within the volute 22 of the centrifugal fan 2. The outlet of the volute 22 of the centrifugal fan 2 is connected to the filter assembly of the island unit. The filter assembly is located below the air vent and is connected to the second air vent. After being accelerated by the centrifugal fan 2, the oil fumes enter the filter assembly, and the filtered gas can then leave the housing 1 through the second air vent and return to the kitchen environment, thereby completing the purification of the kitchen environment. The centrifugal fan 2 includes an impeller 21 and a volute 22. The impeller 21 is rotatably mounted inside the volute 22, which is inclined relative to the horizontal plane. The side of the volute 22 closest to the filter assembly is vertically lower than the side of the volute 22 furthest from the filter assembly. An oil drain hole 220 is provided on the side of the volute 22 closest to the filter assembly. The oil drain hole 220 is vertically opposite to the oil drain outlet provided at the bottom 11 of the housing 1. This allows the oil droplets condensed when the fumes flow inside the volute 22 to flow along the inclined direction of the volute 22 to the lower oil drain hole 220, and then flow out of the island integrated machine through the oil drain outlet provided at the bottom 11 of the housing 1. This achieves automatic discharge of oil accumulated in the air duct, reduces oil sedimentation, avoids affecting the smoke exhaust effect of the island integrated machine, and ensures the performance of the product. In addition, the centrifugal fan 2 is tilted relative to the horizontal plane towards the first air inlet, which not only makes the centrifugal fan 2 more horizontal in the housing 1, thus reducing its space occupation, but also makes the air inlet of the centrifugal fan 2 face the first air inlet, so that the oil fumes can be quickly drawn to the air inlet, improving the purification efficiency of the oil fumes.

[0039] In this embodiment, the plane where the outlet of the volute 22 is located is set at an angle α with the vertical direction, where 8°≤a≤12°. The angle between the plane where the outlet of the volute 22 is located and the vertical direction is equal to the angle between the radial plane of the centrifugal fan 2 and the horizontal plane. If the angle α is greater than 12°, that is, the angle between the radial plane of the centrifugal fan 2 and the horizontal plane is greater than 12°, it will affect the suction effect of the centrifugal fan 2 on oil fumes, resulting in a smaller air intake volume. If the angle α is less than 8°, that is, the angle between the radial plane of the centrifugal fan 2 and the horizontal plane is less than 8°, it will affect the oil discharge effect of the centrifugal fan 2, affect the flow speed of oil droplets, and cause oil to settle in the volute 22.

[0040] Optionally, the island-style integrated unit's duct oil drainage structure also includes a guide component, which is disposed between the first air inlet and the air inlet. The guide component is used to guide the oil fumes from the first air inlet to the air inlet. In the island-style integrated unit's duct oil drainage structure provided in this embodiment, the centrifugal fan 2 is located below the stove 100, while the first air inlet is located on the side of the stove 100. When the oil fumes enter the cavity 10 through the first air inlet, the air inlet is not in the direction of the oil fume flow. Therefore, in order to allow a large amount of oil fumes to flow directly to the air inlet and reduce their flow in various parts of the cavity 10, a guide component is provided to guide the flow of oil fumes and prevent them from flowing to the bottom surface of the stove 100, where oil stains would form. A first air duct is provided inside the housing 1. One end of the first air duct is connected to the first air outlet, and the other end of the first air duct extends to the cavity 10. A guide is provided above the other end to prevent the oil fumes from flowing out of the other end and flowing upward to the bottom surface of the stove 100.

[0041] Furthermore, such as Figure 3 As shown, the plane where the outlet of the volute 22 is located is set at an angle to the vertical direction. A fixing flange 221 is provided at the outlet of the volute 22, and the fixing flange 221 is detachably connected to the filter assembly. The lower end of the fixing flange 221 in the vertical direction is inclined towards the filter assembly. That is, in this embodiment, by setting the outlet of the volute 22 at an angle, the centrifugal fan 2 can be tilted relative to the horizontal plane after the volute 22 is connected to the filter assembly. The air duct of the volute 22 is spiral in shape, and the outlet of the volute 22 has a rectangular structure. The upper end of the rectangular outlet is shorter than the lower end of the rectangular outlet in the extension direction of the air duct outlet. This causes the plane where the outlet of the volute 22 is located to be tilted, and the fixing flange 221 will also be tilted at the same angle after being installed on this plane. In specific implementation, the fixing flange 221 is welded to the outlet of the volute 22. The fixing flange 221 is provided with mounting holes, and fasteners can be used to pass through the filter assembly and connect to the fixing flange 221, thereby realizing the detachable connection between the centrifugal fan 2 and the filter assembly.

[0042] Optionally, such as Figure 4 As shown, the integrated island unit's duct oil drainage structure also includes a connector 222. The connector 222 includes a first connecting part 2221 and a second connecting part. The first connecting part 2221 is circumferentially arranged around and connected to the fixed flange 221. The second connecting part is perpendicular to the plane of the first connecting part 2221. The first connecting part 2221 is connected to the filter assembly radially from the centrifugal fan 2, and the second connecting part is connected to the filter assembly axially from the centrifugal fan 2. The connector 222 cooperates with the fixed flange 221, ensuring that the connection force between the centrifugal fan 2 and the filter assembly exists not only radially but also axially from the centrifugal fan 2, thus guaranteeing the stability of the connection between the tilted centrifugal fan 2 and the filter assembly.

[0043] In this embodiment, the second connecting portion includes a second upper connecting piece 2222 and a second lower connecting piece 2223 arranged axially opposite to each other on the centrifugal fan 2. The connection position between the filter assembly and the centrifugal fan 2 is sandwiched between the second upper connecting piece 2222 and the second lower connecting piece 2223. The second upper connecting piece 2222 abuts against the upper surface of the filter assembly in the vertical direction, and the second lower connecting piece 2223 abuts against the lower surface of the filter assembly in the vertical direction. Both the second upper connecting piece 2222 and the second lower connecting piece 2223 are provided with multiple through holes, through which fasteners can pass and be fixed to the filter assembly.

[0044] Furthermore, the integrated island unit's duct oil drainage structure also includes a support component. This support component is installed at the bottom 11 of the housing 1 and located on the side of the volute 22 furthest from the filter assembly. The support component supports the volute 22. In addition to using a connector 222 to enhance the connection stability between the centrifugal fan 2 and the filter assembly, a support component can also be installed on the side with a larger distance between the volute 22 and the bottom 11 of the housing 1. This support component supports the volute 22 to prevent it from shifting during long-term use. In practice, a shock-absorbing pad can also be wrapped around the side of the support component that abuts against the volute 22 to prevent the volute 22 from vibrating and colliding with the support component during operation, thus avoiding noise.

[0045] Optionally, such as Figure 1 and Figure 2 As shown, a groove 111 is provided at the bottom 11 of the housing 1, and the oil drain port is located at the bottom of the groove 111. The vertical projection of the oil drain hole 220 falls on the bottom of the groove 111. The groove 111 is used to directly receive oil droplets dripping from the oil drain hole 220. When the bottom 11 of the housing 1 is set as a plane, the groove 111 can make the oil droplets gather instead of flowing at the bottom 11 of the housing 1. The gathered oil droplets will be discharged from the oil drain port of the island integrated machine.

[0046] Optionally, such as Figure 1 and Figure 2 As shown, the oil drain structure of the island-style integrated unit also includes an oil cup 3, which is detachably mounted outside the housing 1 and connected to the oil drain port. Two opposing sliding grooves are provided on the outer side of the bottom 11 of the housing 1. The two sides of the oil cup 3 are slidably inserted into the sliding grooves to collect and drain oil droplets from the island-style integrated unit. After a period of use, the oil cup 3 can be removed from the sliding grooves for cleaning.

[0047] This embodiment also provides an island-style integrated appliance, including a cooktop 100 and the aforementioned island-style integrated appliance duct oil drainage structure. The cooktop 100 is installed in the mounting area of ​​the top plate. The cooktop 100 is located close to the first air vent, while the second air vent is located on the side of the first air vent away from the cooktop 100, so that the oil fumes generated during the use of the cooktop 100 can be quickly drawn into the housing 1 for filtration. The filtered and purified gas then returns to the kitchen environment through the second air vent. This island-style integrated unit features an oil drainage structure in its duct. The centrifugal fan 2 is tilted relative to the horizontal plane towards the first air outlet. This not only allows the centrifugal fan 2 to be positioned nearly horizontally within the housing 1, reducing its space occupation, but also ensures that the air inlet of the centrifugal fan 2 faces the first air outlet, enabling the oil fumes to be quickly drawn to the air inlet, thus improving the purification efficiency of the oil fumes. At the same time, it allows oil droplets condensed in the volute 22 to roll under the influence of gravity to the oil drain hole 220, thereby autonomously discharging them from the island-style integrated unit. This effectively addresses the problem of oil accumulation in the duct of the island-style integrated unit, preventing it from affecting the smoke extraction effect, ensuring product performance, and improving the user experience.

[0048] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments.
