Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an oil cup for a range hood and the range hood. Background Art

[0002] The oil cup is a component of the range hood that stores oil stains. In addition to the exhaust of oil smoke during the use of the range hood, a certain proportion of the oil smoke will be cooled inside the range hood and drip into the oil cup along with the oil guide component. Currently, hanging oil cups are mostly used in range hoods. After the user has used the range hood for a period of time, the oil-water mixture in the hanging oil cup needs to be cleaned up. The usual practice is for the user to remove the oil cup and then pour out the oil-water mixture. However, many problems will arise in the process of removing the oil cup and pouring it out. For example, when there is a large amount of oil-water mixture, there is a risk of shaking out when removing the oil cup; in addition, when the user holds the oil cup, due to the unstable center of gravity, the oil-water mixture has the risk of overflowing from the front and back of the oil cup; furthermore, at the end of pouring, due to the small space in the oil cup, it is inconvenient for the user to clean up the oil residue.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN203980387U discloses "An oil receiving cup for a range hood", which includes a cup body with an upper opening, and also includes an oil outlet interface, wherein the oil outlet interface is arranged on the front wall plate, the rear wall plate or the end wall plate at one end of the cup body, and the oil outlet interface is connected with the inner cavity of the cup body; or the oil outlet interface intersects with the front wall plate, the rear wall plate or the end wall plate and the bottom plate at one end of the cup body; the bottom plate of the cup body has a lift angle from one end of the end wall plate where the oil outlet interface is arranged to the other end of the end wall plate; or the bottom plate has a lift angle from the front wall plate to the rear wall plate; or the bottom plate has a lift angle from the rear wall plate to the front wall plate. Due to the adoption of such a structure, when the oil in the oil receiving cup reaches the set liquid level, it can be discharged through the liquid outlet interface without disassembling the oil cup, which is convenient to use; the oil receiving cup will only be disassembled when it needs to be cleaned.

[0004] However, the oil cup in the above patent application still has certain shortcomings. Although it can discharge oil pollution, oil residue will remain at the bottom of the oil cup and in the liquid guide tube, which may easily cause the liquid guide tube to be blocked or have odor for a long time. Therefore, the user needs to specially handle the oil residue in the oil cup, which reduces the user experience. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide an oil cup for a range hood that can conveniently collect and process the oil residue in the oil cup in view of the current status of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a range hood using the above-mentioned oil cup in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the first technical problem is: an oil cup for a range hood, comprising:

[0008] The oil cup body comprises an oil storage chamber with an open top;

[0009] The bottom wall of the oil storage chamber is partially recessed to form a cache recess, and a filter basket for filtering the oil is arranged in the cache recess. An oil outlet is provided on the oil cup body in an area corresponding to the cache recess, and a valve and an oil outlet pipe are connected to the oil outlet. A mounting opening that communicates with the cache recess is also provided on the side wall of the oil cup body. The filter basket can be installed into the cache recess or pulled out from the cache recess through the mounting opening. After the filter basket is assembled in place, the mounting opening on the oil cup body can be closed.

[0010] When it is necessary to clean the oil in the oil storage chamber of the oil cup, the valve can be opened and the oil outlet port of the oil outlet pipe can be lowered to facilitate the flow of oil in the oil cup. During the flow of oil, oil residue (turbid sediment / large particle aggregates) gathers in the filter basket in the buffer recess. After the oil is cleaned, the filter basket can be pulled out from the mounting port of the oil cup body and the oil residue can be poured out, making the cleaning more thorough and less likely to clog the oil outlet pipe and valve.

[0011] In order to facilitate the installation of the filter basket on the oil cup body in a pull-out manner, the filter basket includes a bottom wall and side walls extending upward from the outer periphery of the bottom wall, the side walls and the bottom wall of the filter basket define a filter chamber open at the top, and oil filter holes are distributed on partial areas of the bottom wall and side walls of the filter basket. After the filter basket is assembled in place, a part of the side wall of the filter basket used to close the installation opening on the oil cup body is recorded as an oil baffle, and no oil filter holes are provided on the oil baffle.

[0012] In order to ensure the aesthetics of the oil cup body after the filter basket is installed in place, the installation port is opened on the front side wall of the oil cup body, and the oil baffle plate of the filter basket is a flat structure. When the filter basket is assembled in place on the oil cup body, the outer wall surface of the oil baffle plate is flush with the outer wall surface of the front side wall of the oil cup body.

[0013] Generally speaking, the filter basket needs to be suspended, that is, a gap needs to be left between the filter basket and the inner wall of the cache recess. For this purpose, the top opening of the cache recess is an oil drop port, and the left and right opposite side edges of the oil drop port have a first support plate and a second support plate extending toward each other. The filter basket includes a first side wall and a second side wall opposite to each other, and the top edges of the first side wall and the second side wall respectively have a first stop edge and a second stop edge that are turned over and extended toward the outside of the filter chamber. When the filter basket is assembled in place on the oil cup body, the first stop edge is placed on the first support plate, and the second stop edge is placed on the second stop edge.

[0014] In order to enable the oil residue to smoothly enter the filter basket during the flow of oil and avoid residue at the joint position of the filter basket and the oil cup body, the top surface of the first support plate is provided with a concave first step, the top surface of the second support plate is provided with a concave second step, the first baffle edge is placed on the first step of the first support plate, and the top surface of the first baffle edge is flush with the top surface of the bottom wall of the oil storage chamber, and the second baffle edge is placed on the second step of the second support plate, and the top surface of the second baffle edge is flush with the top surface of the bottom wall of the oil storage chamber.

[0015] In order to ensure the overall aesthetics of the oil cup, the bottom of the oil cup body also has an upward concave receiving groove, the valve and the oil outlet pipe are both received in the receiving groove, and the oil outlet is opposite to the receiving groove. It is conceivable that the above-mentioned receiving groove can also be changed to an outward convex protrusion structure, so that the oil outlet pipe can be circumferentially surrounded and the length of the oil pipe can be increased.

[0016] As an improvement, the oil cup body is in an elongated strip shape as a whole, and the receiving groove is extended along the length direction of the oil cup body.

[0017] In order to prevent the oil outlet pipe from easily falling out of the receiving groove, a buckle for restraining the oil outlet pipe is also provided in the receiving groove.

[0018] In order to enable the oil residue to flow more smoothly to the location of the buffer recess, the bottom wall of the oil storage chamber is inclined as a whole, and the buffer recess is located at the lowest position of the bottom wall of the oil storage chamber.

[0019] As an improvement, the oil cup body is in the shape of an elongated strip as a whole, and the bottom wall of the oil storage chamber gradually slopes downward from the first end to the second end of the oil cup body, and the buffer recess is located at the second end of the oil cup body.

[0020] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, comprising a body and an oil cup arranged on the body, wherein the oil cup adopts the above-mentioned oil cup for the range hood.

[0021] In order to facilitate users to check the oil level status of the oil cup in real time, it also includes a sensor component for identifying the oil level in the oil storage chamber of the oil cup body and transmitting the identified oil level signal to the control system of the range hood, and a display screen arranged on the body for displaying the oil level information in the oil storage chamber, and the display screen is electrically connected to the control system of the range hood.

[0022] Compared with the prior art, the utility model has the following advantages: when it is necessary to clean the oil in the oil storage chamber of the oil cup, the valve can be opened and the oil outlet port of the oil outlet pipe can be lowered to facilitate the flow of oil in the oil cup. During the flow of the oil, the oil residue (turbid sediment / large particle aggregates) gathers in the filter basket in the buffer recess. After the oil is cleaned, the filter basket can be pulled out from the mounting port of the oil cup body and the oil residue can be poured out, making the cleaning more thorough and not easy to clog the oil outlet pipe and valve. The amount of oil in the oil cup is displayed on the range hood control screen, and the user is intelligently reminded to clean the oil cup to avoid overflow of too much oil when the user forgets to clean it after using it for too long. The oil cup does not need to be removed. When the user is intelligently reminded, he only needs to remove the oil outlet pipe hidden in the storage groove and open the valve to allow the oil to flow out by gravity. When the oil is cleaned, the valve is closed and the oil outlet pipe is stuck in the buckle of the storage groove. The oil outlet pipe and valve are hidden in the storage groove at the bottom of the oil cup body, which will not affect the overall aesthetics of the oil cup. BRIEF DESCRIPTION OF THE DRAWINGS
