Description

Technical Field

[0001] This utility model relates to the field of oil fume emission technology, and in particular to an oil discharge device and oil fume emission equipment. Background Technology

[0002] To improve the aesthetics of the all-in-one machine, existing technology proposes a design that hides the oil cup inside the cabinet, allowing users to check it periodically to see if it needs cleaning. However, in actual use, it has been found that if users do not check the oil cup regularly, it is easy for waste oil to overflow into the cabinet after it is full and not emptied in time, seriously affecting the user experience.

[0003] To address this, existing technology proposes using two oil cups: an upper oil cup and a lower oil cup located below the upper one. The lower oil cup, situated below the oil receiving tray, collects the waste oil. An oil pump transfers the waste oil from the lower oil cup to the upper oil cup. A recessed area is provided on the upper surface of the integrated stove's smoke baffle, and the upper oil cup is detachably placed within this area. The smoke baffle is connected to a removable cover to seal the opening in the recessed area. A transparent window is provided on the front of the smoke baffle, and the upper oil cup is made of transparent material, allowing observation of the waste oil level through the window. Once full, the cover is opened, the upper oil cup is removed, and the waste oil is poured out.

[0004] However, in addition to creating a window for installing a transparent viewing window on the smoke shield and installing the window, an opening for removing and placing the oil cup also needs to be created on the smoke shield, and a removable cover must be fitted to the opening. This makes the smoke shield processing cumbersome, reduces the processing efficiency of the smoke shield, and increases the processing cost of the smoke shield. Utility Model Content

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0054] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. 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.

[0057] The present invention provides an oil draining device and an oil fume emission device including the oil draining device. The oil fume emission device can be an integrated stove with oil fume emission function, a stove-and-range appliance with oil fume emission function, or a range hood with oil fume emission function, etc. The following describes the oil draining device and the structure of the stove-and-range appliance with the oil draining device as an example.

[0058] like Figures 1 to 3As shown, the oil draining device includes a housing, an oil cup 2, a sealing part 3, and an oil collection tray 7. The housing has a placement chamber, and one side of the placement chamber has an opening to form a take-out port 111, which is located in the visible area of ​​the housing. The oil cup 2 is placed in the placement chamber through the take-out port 111. The oil cup 2 is used to temporarily store waste oil. The sealing part 3 is used to open and close the take-out port 111. The sealing part 3 is a transparent structure that forms a viewing window for observing the amount of oil in the oil cup 2.

[0059] Because the inlet / outlet 111 is located in a visible area of ​​the housing, it is convenient for the user to observe the oil level in the oil cup 2 through the sealing part 3 to determine whether the oil cup 2 needs to be cleaned. When the oil cup 2 needs to be cleaned, it is removed from the placement chamber for cleaning. This oil draining device uses a transparent structure for the sealing part 3 to form a viewing window, allowing the sealing part 3 to function as both opening and closing the inlet / outlet 111 and observing the oil level in the oil cup 2. Compared to the prior art, which uses separate covers for opening and closing the inlet / outlet 111 and viewing windows for observing the oil level in the oil cup 2, this improves the integration of the oil draining device, simplifies its structure, and reduces its cost.

[0060] For example, such as Figure 1 As shown, the take-up and put-out port 111 is located on the top wall of the housing. Specifically, the housing includes a panel shell 12 and a control panel 11. The panel shell 12 has a top opening structure. The control panel 11 is connected to the panel shell 12 to block the top opening of the panel shell 12. The control panel 11 refers to the area of ​​the integrated range hood and stove where various buttons are provided. The operation area of ​​the control panel 11 is located on the upper surface of the control panel 11, that is, the operation area of ​​the control panel 11 is a visible area. The take-up and put-out port 111 is opened on the upper surface of the control panel 11.

[0061] Furthermore, such as Figure 3 and Figure 4 As shown, the oil cup 2 includes a cup body with an opening at the top and a cup lid covering the cup body. When the opening 111 is opened on the upper surface of the control panel 11, the cup lid is transparent and forms the aforementioned sealing part 3.

[0062] It should be noted that the smoke extraction device is an integrated stove or a range hood, and the intake port 111 can also be located on the side wall of the housing in the horizontal direction. Specifically, the intake port 111 is located on the front side or left and right sides of the smoke baffle. In this case, the body of the oil cup 2 is made of transparent structure, and the body of the oil cup 2 forms a sealing part 3, which blocks the intake port 111.

[0063] In other embodiments, the sealing part 3 can be detachably connected to the housing. Before removing the oil cup 2, the sealing part 3 can be removed. The connection between the sealing part 3 and the housing can be a plug-in, snap-fit, or threaded connection, etc., which are not specifically limited here. The sealing part 3 can also be movably connected to the housing. For example, the sealing part 3 can move horizontally and rise and fall relative to the housing, so that the sealing part 3 can move to one side of the oil cup 2 in the horizontal direction; or the sealing part 3 can be rotatably connected to the housing, so that the sealing part 3 can rotate greater than or equal to 90°, so that the sealing part 3 will not affect the rising and falling of the oil cup 2.

[0064] like Figures 5 to 7 As shown, during the process of transferring waste oil from the oil collection tray 7 to the oil cup 2, the waste oil may splash onto the inner surface of the sealing part 3, making it impossible for the user to accurately determine the amount of oil in the oil cup 2 when observing it through the sealing part 3. Therefore, the oil discharge device further includes a controller, a liquid level detection element 5, and a prompting unit. Both the liquid level detection element 5 and the prompting unit are electrically connected to the controller. The liquid level detection element 5 detects the liquid level in the oil cup 2, and the prompting unit reminds the user that the liquid level in the oil cup 2 has reached the preset cleaning level. For example, the liquid level detection element 5 is a liquid level sensor. It should be noted that the prompting unit is a display built into the fume extraction device, or it can be a mobile phone display. That is, when the detection signal from the liquid level detection element 5 determines that the liquid level in the oil cup 2 has reached the preset cleaning level, the controller sends a signal to the prompting unit to remind the user to clean the waste oil in the oil cup 2 in a timely manner to avoid oil overflow. The aforementioned preset cleaning level is a known value determined based on the volume of the oil cup 2 and is embedded in the controller in advance.

[0065] Furthermore, such as Figure 1 , Figure 3 and Figure 8 As shown, with the opening 111 located on the upper surface of the control panel 11, when the oil cup 2 is placed in the placement chamber, the cup lid is flush with the upper surface of the control panel 11, that is, the upper surface of the sealing part 3 is flush with the upper surface of the control panel 11, which prevents the cup lid from protruding from the upper surface of the control panel 11 and affecting the aesthetics, thus improving the aesthetics of the integrated range hood and stove.

[0066] Furthermore, such as Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the oil draining device also includes a drive unit 4, which is used to push the oil cup 2 so that at least a portion of the oil cup 2 extends out of the pick-up and drop-off port 111. When it is necessary to remove the oil cup 2 for cleaning, the drive unit 4 pushes the oil cup 2 so that at least a portion of the oil cup 2 extends out of the pick-up and drop-off port 111, making it convenient for the user to pick up the oil cup 2.

[0067] Specifically, the drive unit 4 includes a cam 42 and a rotary motor 41. The outer peripheral surface of the cam 42 can contact the outer wall of the oil cup 2 on the side opposite to the pick-up / placement port 111. The rotary motor 41 is installed inside the housing. Specifically, the rotary motor 41 is located in the space enclosed by the panel housing 12 and the control panel 11. The rotary motor 41 is used to drive the cam 42 to rotate. By driving the cam 42 to rotate through the rotary motor 41, the cam 42 pushes the oil cup 2 out of the pick-up / placement port 111.

[0068] For example, when the loading and unloading port 111 is located on the top wall of the control panel 11, a support member 43 is fixedly installed in the placement chamber. The support member 43 is provided with a through hole 431 extending vertically. The through hole 431 has an upward-facing stepped surface. The oil cup 2 is supported by the stepped surface. The cam 42 can extend into the through hole 431 from below and abut against the outer bottom wall of the oil cup 2. Specifically, two fixing posts are protruding from the bottom wall of the panel shell 12. The fixing posts have a stepped structure. Both ends of the support member 43 are provided with ear plates. The fixing posts are provided through holes on the ear plates. The fixing posts and the through holes are interference-fitted. The support member 43 is supported by the stepped surface of the fixing posts to fix the support member 43 to the panel shell 12.

[0069] When oil cup 2 is in the placement chamber, it is supported by the stepped surface, and the outer circumferential surface of the base circle of cam 42 contacts the bottom surface of oil cup 2. When oil cup 2 needs to be removed, the rotary motor 41 drives cam 42 to rotate. The push portion of cam 42 extends into the through hole 431 and begins to contact the bottom surface of oil cup 2. As cam 42 continues to rotate, oil cup 2 is pushed upward by cam 42 until the distal end of cam 42 contacts oil cup 2. At this time, the upper cup body of oil cup 2 has extended out of the pick-up and drop-off port 111, and the user can hold the upper cup body of oil cup 2 to remove it. After the lower end of the cleaned oil cup 2 is inserted into the placement chamber through the pick-up and drop-off port 111, the rotary motor 41 drives cam 42 to rotate in the opposite direction until oil cup 2 is supported by the stepped surface.

[0070] To facilitate control of the rotary motor 41, the control panel 11 is equipped with two control buttons. One button is used to control the rotary motor 41 to drive the cam 42 to rotate so that the upper part of the oil cup 2 extends out of the pick-up and drop opening 111. The other button is used to control the rotary motor 41 to drive the cam 42 to rotate in the opposite direction so that the oil cup 2 falls down to be supported by the stepped surface.

[0071] It should be noted that the drive unit 4 can also adopt structures that can achieve linear extension and retraction, such as electric actuators, which will not be listed here.

[0072] Furthermore, such as Figure 10As shown, the oil collection tray 7 is located below the oil cup 2. The bottom of the oil collection tray 7 is connected to the oil cup 2 through the oil drain pipe 6, and an oil pump 40 is installed on the oil drain pipe 6. The oil pump 40 sends the waste oil collected by the oil collection tray 7 into the oil cup 2, so that the oil cup 2 can be placed in the visible area of ​​the housing.

[0073] Furthermore, such as Figure 10 As shown, the oil collection tray 7 is equipped with an oil quantity determination unit for determining the amount of waste oil in the oil collection tray 7. Exemplarily, the oil quantity determination unit includes a weight detection element 20. The detection part of the weight detection element 20 is inserted into the oil collection tray 7 from the inner bottom wall of the oil collection tray 7. The weight detection element 20 is used to detect the weight of the waste oil in the oil collection tray 7. It should be noted that the weight detection element 20 can be a pressure sensor. The weight of the waste oil in the oil collection tray 7 is determined by sensing the pressure change caused by the gradual increase of waste oil in the oil collection tray 7. This is a commonly used measurement method in the art and will not be specifically limited here.

[0074] The weight detection element 20 is electrically connected to the controller of the fume emission equipment. The controller determines whether the weight of waste oil in the oil collection tray 7 has reached the preset weight based on the detection signal from the weight detection element 20. When the weight of waste oil in the oil collection tray 7 reaches the preset weight, the controller controls the oil pump 40 to send the waste oil accumulated in the oil collection tray 7 to the oil cup 2. The aforementioned preset weight is a known value determined based on the volume of the oil collection tray 7 and is embedded in the controller in advance.

[0075] In other embodiments, a timer can be used to replace the oil volume determination unit. The timer accumulates the working time of the integrated range hood and stove, and resets the accumulated time to zero after each stop of the oil pump 40, then continues to accumulate the working time of the integrated range hood and stove. When the accumulated working time of the integrated range hood and stove reaches a preset time, it indicates that the waste oil in the oil collection tray 7 needs to be cleaned. The controller controls the oil pump 40 to send the waste oil accumulated in the oil collection tray 7 to the oil cup 2. The preset time is a known value determined based on the volume of the oil collection tray 7 and is embedded in the controller in advance.

[0076] like Figure 9 and Figure 10 As shown, in order to prevent oil leakage caused by the disconnection between the oil drain pipe 6 and the oil cup 2 during the removal of the oil cup 2, and to avoid interference between the oil drain pipe 6 and the removal of the oil cup 2, the oil drain pipe 6 is further made of a flexible hose. The oil drain pipe 6 includes a base pipe section and an extension pipe section. One end of the base pipe section is connected to the bottom of the oil collection tray 7, and the other end of the base pipe section is connected to the oil cup 2 through the extension pipe section and is detachably connected. The oil pump 40 is installed on the base pipe section, and the extension pipe section can be pulled out of the removal port 111 by the oil cup 2.

[0077] During the removal of oil cup 2, the extended pipe section is pulled out and then removed from oil cup 2 to facilitate subsequent cleaning of oil cup 2.

[0078] For example, the oil cup 2 is provided with a mounting hole 21, and one end of the oil drain pipe 6 is inserted into the mounting hole 21 with an interference fit. The oil drain pipe 6 and the oil cup 2 are easy to disassemble and assemble, and waste oil can be prevented from leaking through the contact surface between the oil drain pipe 6 and the mounting hole 21.

[0079] In other embodiments, one end of the oil drain pipe 6 can be connected to the bottom of the oil collection tray 7, and the other end can be connected to the oil cup 2 in a detachable manner. The oil drain pipe 6 is a telescopic pipe, and the oil pump 40 is located on the oil drain pipe 6. The oil drain pipe 6 is a telescopic pipe, such as a corrugated pipe, so that when the oil cup 2 is disassembled, the end of the oil drain pipe 6 connected to the oil cup 2 can be pulled out along with the oil cup 2, so that the connection between the oil drain pipe 6 and the oil cup 2 will not be disconnected during the removal and placement of the oil cup 2.

[0080] Furthermore, such as Figure 3 , Figure 7 and Figure 8 As shown, the position where oil cup 2 is connected to the drain pipe 6 is higher than the preset cleaning liquid level. After removing oil cup 2, disconnect the drain pipe 6 and oil cup 2, and then clean oil cup 2; keeping the position where oil cup 2 is connected to the drain pipe 6 higher than the preset cleaning liquid level can prevent waste oil in oil cup 2 from overflowing through the position where oil cup 2 is connected to the drain pipe 6 after the drain pipe 6 and oil cup 2 are disconnected.

[0081] like Figure 10 As shown, the fume emission device provided by this utility model also includes a fume collection pipe 8, a fan 9, a fume exhaust pipe 10, and a fume filter unit. The upper end of the fume collection pipe 8 is located above the housing, and the lower end of the fume collection pipe 8 extends into the housing. The fan 9 is located inside the housing, and the inlet of the fan 9 is connected to the outlet end of the fume collection pipe 8. The lower end of the fume exhaust pipe 10 is located inside the housing and is connected to the outlet of the fan 9. The upper end of the fume exhaust pipe 10 extends upward, and the upper end of the fume exhaust pipe 10 is not lower than the upper surface of the housing. The fume filter unit is located in the fume collection pipe 8.

[0082] When the fume extraction device is an integrated range hood and stove unit, the fan 9 operates, creating a negative pressure within the fume collection duct 8. The fumes generated during the operation of the heating appliance 30 located on the control panel 11 are drawn into the fume collection duct 8. After passing through the fan 9, the fumes are discharged through the upper end of the exhaust duct 10. During this process, the fumes are filtered by the fume filtration unit and then directly discharged into the space where the fume extraction device is located, such as the kitchen.

[0083] Although the fumes are filtered, there may still be a small amount of oil. Extending the upper end of the exhaust pipe 10 upwards and above the upper surface of the housing can prevent the small amount of oil fumes in the exhaust gas from polluting the housing.

[0084] In other embodiments, the fume filter unit may be located inside the exhaust duct 10, or the fume filter unit may be located in both the smoke collection duct 8 and the exhaust duct 10. The fume filter unit located in the exhaust duct 10 has a higher filtration accuracy than the fume filter unit located in the smoke collection duct 8.

[0085] Specifically, the housing also includes a shell body, which is located below the panel shell 12. The shell body and the panel shell 12 are connected to form a smoke chamber. The lower end of the smoke exhaust pipe 10, the lower end of the smoke collection pipe 8, the fan 9 and the oil collection plate 7 are all located inside the smoke chamber.

[0086] Furthermore, such as Figure 10 As shown, the upper end of the exhaust duct 10 is lower than the upper end of the smoke collection duct 8, and the upper end of the exhaust duct 10 is located on the side of the upper end of the smoke collection duct 8 that is away from the heating appliance 30. This prevents the smoke discharged from the upper end of the exhaust duct 10 from flowing to the side where the heating appliance 30 is located and affecting the user experience.

[0087] Furthermore, such as Figure 2 As shown, the oil collection tray 7 is located below the fan 9, the exhaust pipe 10, and the smoke collection pipe 8. A first oil leakage hole 81 is provided at the lowest position of the smoke collection pipe 8, a second oil leakage hole 91 is provided at the lowest position of the volute of the fan 9, and a third oil leakage hole 101 is provided at the lowest position of the exhaust pipe 10. The oil collection tray 7 has a top-opening structure. The first oil leakage hole 81, the second oil leakage hole 91, and the third oil leakage hole 101 are all positioned directly opposite the top opening of the oil collection tray 7. This allows the oil accumulated in the smoke collection pipe 8 to drip through the first oil leakage hole 81 into the oil collection tray 7 below, the oil accumulated in the volute to drip through the second oil leakage hole 91 into the oil collection tray 7 below, and the oil accumulated in the exhaust pipe 10 to drip through the third oil leakage hole 101 into the oil collection tray 7 below.

[0088] The oil collecting tray 7 includes a box body and a converging part. The inner wall of the box body gradually concaves downward from the outer periphery to the middle to form an oil collecting cavity. An oil dripping hole is provided at the lowest point of the oil collecting cavity. The converging part is located below the box body. The inner cavity of the converging part is connected to the oil collecting cavity through the oil dripping hole.
