Description

Technical Field

[0001] This application relates to the field of range hoods, and particularly to an oil cup for a range hood and an oil-absorbing element for the oil cup of a range hood.

Background Art

[0002] In Asian regions, due to the traditional cooking habit of stir-frying, the oil content in the smoke generated during cooking is particularly high. Therefore, a range hood for exhausting the cooking fumes generated during cooking has become an essential important household appliance in daily life. With the continuous improvement of people's requirements for the quality of life, range hoods are also constantly upgraded and improved. For example, in order to facilitate users to clean the oil cup, a solution of placing an oil-absorbing cotton or oil-absorbing paper and other oil-absorbing elements in the oil cup has been proposed. When the oil-absorbing element is saturated with oil, it is generally directly discarded and replaced. In this way, it not only causes waste of resources, increases the customer's use cost, but also is not environmentally friendly. On the other hand, the oil-absorbing element fills the bottom of the oil cup, and the dripping grease often concentrates on a certain area of the oil cup. In this way, although some areas of the oil-absorbing element can still absorb grease, the oil-absorbing element needs to be replaced due to the saturation of the local area of the oil-absorbing element, which causes waste of resources to a certain extent.

[0003] Unless there is sufficient evidence to support it, the prior art described herein does not mean that these prior arts were known to those of ordinary skill in the art in the field related to this application before the filing date of this application.

Summary of the Invention

[0004] An object of an embodiment of this application is to propose an improved range hood, its oil cup, and oil-absorbing element for at least one of the above technical problems and / or other possible technical problems not mentioned in this application.

[0005] According to a first aspect of this application, an embodiment of this application provides an oil cup for a range hood. The oil cup is configured to be detachably mounted on the range hood. The oil cup is in the shape of an open-upward groove. When the oil cup is mounted on the range hood, the bottom of the groove of the oil cup extends downwardly and obliquely from its top edge to its bottom edge. The bottom edge of the bottom of the groove of the oil cup is connected to the groove wall of the oil cup to form a first edge. When the oil cup is mounted on the range hood, the first edge is at the lowest point of the oil cup. Thus, the grease collected by the oil cup is concentrated at the first edge, making the cleaning of the oil cup more targeted. The oil cup for a range hood proposed in this application is a breakthrough in the existing oil cup structure with a horizontally arranged bottom of the groove, thereby bringing various new possibilities.

[0006] In one or some embodiments, when the oil cup is installed on the range hood, the inclination angle β of the bottom of the oil cup relative to the horizontal plane satisfies: 5° ≤ β ≤ 8°. Thus, it can ensure that the bottom of the oil cup has a certain inclination angle, so that the grease collected in the oil cup concentrates at the first edge; and it can also ensure that the inclination angle of the bottom is not too large, so that the oil cup has a larger accommodating space.

[0007] In one or some embodiments, the top edge of the bottom of the oil cup is connected to the inner wall of the oil cup to form a second edge; an oil-absorbing element is placed in the oil cup; among the first edge and the second edge, the oil-absorbing element is only filled in the first edge. The oil-absorbing element is only filled in the first edge among the first edge and the second edge. Thus, the volume of the oil-absorbing element is small and the cost is saved. Moreover, the oil-absorbing element is filled in the first edge at the lowest point of the oil cup, with high grease adsorption efficiency and high utilization rate of the oil-absorbing element itself.

[0008] In one or some embodiments, the oil-absorbing element is adapted to the inner cavity of the first edge.

[0009] In one or some embodiments, the oil cup is strip-shaped; and / or

[0011] In one or some embodiments, the oil-absorbing element is in the shape of a straight triangular prism; only one side of the two bottom surfaces and three side surfaces of the oil-absorbing element is exposed, and the others are attached to the inner wall of the oil cup.

[0012] In one or some embodiments, the oil-absorbing element is a one-piece formed by melamine formaldehyde resin; and / or

[0013] An easy-to-clean coating is provided on the outer surface of the oil-absorbing element; and / or

[0014] An easy-to-clean coating is provided on the inner wall of the oil cup; and / or

[0015] The first edge is an acute angle, and the second edge is an obtuse angle.

[0016] In one or some embodiments, when the oil cup is installed on the range hood, the bottom of the oil cup extends downward from its top edge to its bottom edge in a front-to-back direction; or

[0017] When the oil cup is installed on the range hood, the bottom of the oil cup extends downward from its top edge to its bottom edge in a back-to-front direction.

[0018] In one or some embodiments, when the oil cup is installed on the range hood, the bottom of the groove of the oil cup extends downwardly and obliquely from the top edge to the bottom edge thereof from front to back, and the first edge is located at the rear side of the second edge; the groove wall connected to the bottom edge of the bottom of the groove of the oil cup is vertically arranged; the groove wall connected to the top edge of the bottom of the groove of the oil cup is arranged downwardly and obliquely from front to back.

Detailed implementation manners

[0031] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by this application clearer, the following will further elaborate on this application in combination with the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain this application, rather than to limit the protection scope of this application. And each embodiment may share the same view or multiple views for description, but all the features appearing in the same view cannot be interpreted as the features that a certain embodiment must have. On the contrary, as long as they are not mutually exclusive technically, they can be combined in any suitable way. Moreover, for the sake of simplicity, different embodiments in different aspects may be presented in the same specific design, however, this presentation does not mean that the embodiments in these aspects should appear together. All possible decompositions and / or combinations of embodiments and / or technical features should also consider the description in the specification and the content that can be directly and unambiguously determined by those skilled in the art based on the description in the specification.

[0032] This application proposes an embodiment of an oil cup for a range hood, as Figures 1 to 4 shown, in the shape of an open-upward groove. The oil cup is configured to be detachably installed on the range hood. Specifically, the oil cup is provided with a hook for hanging the oil cup on the range hood body. It should be noted that when the oil cup is installed on the range hood, its opening faces upward so as to receive the grease filtered by the range hood. Specifically, the grease filtered by the range hood flows downward under the action of gravity, passes through the opening of the oil cup and flows into the oil cup.

[0033] The oil cup includes a bottom 3 of the groove and a ring of groove walls protruding upward from the edge of the bottom 3 of the groove. Thus, the bottom 3 of the groove and the ring of groove walls together enclose an open-upward groove for containing grease. The ring of groove walls includes a left side wall 6, a first groove wall 11, a right side wall 7 and a second groove wall 12 that are connected in sequence, as Figure 2 and 3 shown.

[0034] When the oil cup is installed on the range hood, the bottom of the groove 3 of the oil cup extends downward and obliquely from its top edge 4 to its bottom edge 5. Specifically, when the oil cup is installed on the range hood, the bottom of the groove 3 of the oil cup extends downward and obliquely from its top edge 4 to its bottom edge 5 from front to back, asFigure 1 As shown. It should be noted that Figure 1 Although the body of the range hood is not shown in [description], when the oil cup is installed on the range hood, the oil cup on the left view of the range hood is roughly as Figure 1 shown.

[0035] When the oil cup is installed on the range hood, the inclination angle β of the bottom of the oil cup 3 relative to the horizontal plane satisfies: 5° ≤ β ≤ 8°. For the inclination angle β of the bottom of the oil cup 3 relative to the horizontal plane, see Figure 1 . It should be noted that if the inclination angle β of the bottom of the oil cup 3 relative to the horizontal plane is too large, given the fixed length, width, and height dimensions of the oil cup, the accommodating space of the oil cup will be small and the oil collection amount will be small. If the inclination angle β of the bottom of the oil cup 3 relative to the horizontal plane is too small, the oil guiding effect of the bottom of the oil cup 3 will be poor. Through a large number of experiments, it is found that when the inclination angle β of the bottom of the oil cup 3 relative to the horizontal plane satisfies 5° ≤ β ≤ 8°, both can be taken into account, with a relatively large accommodating space and a good oil guiding effect of the bottom 3.

[0036] The bottom edge 5 of the bottom of the oil cup 3 is joined to the wall of the oil cup to form a first edge 1. In other words, the bottom edge 5 of the bottom of the oil cup 3 and the wall of the oil cup joined by this bottom edge 5 form a first edge 1. The top edge 4 of the bottom of the oil cup 3 is joined to the wall of the oil cup to form a second edge 2. In other words, the top edge 4 of the bottom of the oil cup 3 and the wall of the oil cup joined by this top edge 4 form a second edge 2. Specifically, the bottom edge 5 of the bottom of the oil cup 3 is joined to the first wall 11 of the oil cup to form a first edge 1, and the top edge 4 of the bottom of the oil cup 3 is joined to the second wall 12 of the oil cup to form a second edge 2, as Figure 1 and 4 shown.

[0037] When the oil cup is installed on the range hood, the bottom of the oil cup 3 extends downward and backward from its top edge 4 to its bottom edge 5, and the first edge 1 is located behind the second edge 2. When the oil cup is installed on the range hood, the first edge 1 is at the lowest point of the oil cup, as Figure 1 shown. Thus, the inclined bottom 3 is suitable for guiding the grease towards the first edge 1.

[0038] The wall joined by the bottom edge 5 of the bottom of the oil cup 3 is vertically arranged, and the wall joined by the top edge 4 of the bottom of the oil cup 3 is inclined downward from front to back. In other words, the first wall 11 joined by the bottom edge 5 of the bottom of the oil cup 3 is vertically arranged, and the second wall 12 joined by the top edge 4 of the bottom of the oil cup 3 is inclined downward from front to back. The vertical arrangement of the first wall 11 enables the first wall 11 to be suitable for abutting against the wall for hanging the range hood. Thus, it is ensured that the oil cup has sufficient width and a relatively large accommodating space.

[0039] An oil-absorbing element 8 is placed in the oil cup, asFigure 3 and 4 As shown. The oil-absorbing element 8 is arranged to be suitable for adsorbing the grease in the oil cup. Through the opening of the oil cup, the oil-absorbing element 8 is placed into the oil cup. Through the opening of the oil cup, the oil-absorbing element 8 placed in the oil cup is taken out. Among the first edge 1 and the second edge 2, the oil-absorbing element 8 only fills the first edge 1.

[0040] The oil cup is strip-shaped. The inner wall of the oil cup is provided with an easy-to-clean coating. The easy-to-clean coating provided on the inner wall of the oil cup satisfies: the oil contact angle ≥ 45°, and the water contact angle ≥ 90°. The easy-to-clean coating that meets the above conditions is not easy to adhere to grease and is convenient for cleaning the inner wall of the oil cup. The first edge 1 is an acute angle, and the second edge 2 is an obtuse angle, as Figure 1 and 4 shown. The second edge 2 is set as an obtuse angle, which is also convenient for cleaning the inner wall of the oil cup.

[0041] The oil-absorbing element 8 is in the shape of a straight triangular prism, as Figure 2 shown. The oil-absorbing element 8 in the shape of a straight triangular prism is convenient for being placed in a dishwasher for cleaning. The oil-absorbing element 8 is adapted to the inner cavity of the first edge 1. Thus, to a certain extent, the oil-absorbing element 8 separates the inner cavity of the first edge 1 from the grease, which helps to keep the inner cavity of the first edge 1 clean. For the two bottom surfaces and three side surfaces of the oil-absorbing element 8 in the shape of a straight triangular prism, only one side surface is exposed, and the others are all in contact with the inner wall of the oil cup, as Figure 3 and 4 shown. The exposed side surface 9 in the figure is the exposed side surface of the oil-absorbing element 8. Specifically, one bottom surface of the oil-absorbing element 8 is in contact with the inner surface of the left side wall 6 of the oil cup, and the other bottom surface of the oil-absorbing element 8 is in contact with the inner surface of the right side wall 7 of the oil cup. Among the three side surfaces of the oil-absorbing element 8, one is in contact with the inner surface of the first groove wall 11 of the oil cup, one is in contact with the inner surface of the bottom of the groove of the oil cup, and one is the exposed side surface 9.

[0042] The bottom edge of the exposed side surface 9 is connected to the bottom of the groove of the oil cup not covered by the oil-absorbing element 8. The exposed side surface 9 and the inner surface of the bottom of the groove of the oil cup not covered by the oil-absorbing element 8 form an obtuse angle, as Figure 4 shown.

[0043] The main oil path 10 is as shown by the dotted arrow marked with the reference numeral 10 in the Figure 4 drawing. Part of the grease filtered by the range hood directly drips down onto the exposed side surface 9 of the oil-absorbing element 8. Another part of the grease filtered by the range hood drips down onto the inner surface of the bottom of the groove of the oil cup not covered by the oil-absorbing element 8, and then flows along the inner surface of the bottom of the groove of the oil cup towards the first edge 1 at the lowest point of the oil cup under the action of gravity, and finally is adsorbed by the oil-absorbing element 8 filled in the first edge 1.

[0044] The oil-absorbing element 8 is an integrally formed melamine formaldehyde resin part. It should be noted that the oil-absorbing element 8 can be made only of integrally formed melamine formaldehyde resin, or the oil-absorbing element 8 can be integrally formed with melamine formaldehyde resin and other materials.

[0045] An easy-to-clean coating is provided on the outer surface of the oil-absorbing element 8. The oil-absorbing element 8 is arranged to be suitable for repeated use. In other words, after the oil-absorbing element 8 adsorbs oil, it is suitable for being cleaned to remove the oil and then put back into the oil cup for use again, adsorbing oil again, then being cleaned to remove the oil again, and then being put back into the oil cup for use again, and so on in a cycle. Preferably, the oil-absorbing element 8 after adsorbing oil is put into a dishwasher for cleaning. Since an easy-to-clean coating is provided on the outer surface of the oil-absorbing element 8, the oil is sucked into the outer surface of the oil-absorbing element 8, and less oil adheres to the outer surface of the oil-absorbing element 8, which is convenient for the user to hold the oil-absorbing element 8 for cleaning operations.

[0046] Exemplarily, the present application proposes another embodiment of an oil cup for a range hood. When the oil cup is installed on the range hood, the bottom 3 of the groove of the oil cup extends obliquely downward from its top edge 4 to its bottom edge 5 from back to front. The differences between this embodiment and the above embodiment are mainly emphasized. For the same or similar parts of this embodiment, reference can be made to the above embodiment.

[0047] The present application also proposes an embodiment of a range hood, which includes a body and the above oil cup embodiment. The oil cup is suspended from the body. The body includes a casing and a smoke collecting hood arranged in sequence from top to bottom. A blower is arranged in the casing to form a negative pressure and generate an air flow for exhausting cooking fumes. Preferably, the oil cup is suspended from the smoke collecting hood.

[0048] The present application also proposes an embodiment of an oil-absorbing element 8 for an oil cup of a range hood. The oil-absorbing element 8 is an integrally formed melamine formaldehyde resin part. The oil-absorbing element 8 is made of melamine formaldehyde resin. Thus, the oil-absorbing element 8 has a good oil absorption effect and is suitable for being reused after being cleaned. It should be noted that the oil-absorbing element 8 can be made only of integrally formed melamine formaldehyde resin, or the oil-absorbing element 8 can be integrally formed with melamine formaldehyde resin and other materials.

[0049] The oil-absorbing element 8 is in the shape of a right triangular prism, such as Figure 2As shown. An easy-to-clean coating is provided on the outer surface of the oil-absorbing element 8. The oil-absorbing element 8 is configured to be suitable for reuse. In other words, after the oil-absorbing element 8 adsorbs oil, it is suitable to be cleaned to remove the oil and then put back into the oil cup for use again, adsorb oil again, then be cleaned to remove the oil again, and then put back into the oil cup for use again, and so on in a cycle. Preferably, the oil-absorbing element 8 after adsorbing oil is put into a dishwasher for cleaning. Since an easy-to-clean coating is provided on the outer surface of the oil-absorbing element 8, the oil is sucked into the outer surface of the oil-absorbing element 8, and there is less oil adhering to the outer surface of the oil-absorbing element 8, which is convenient for the user to hold the oil-absorbing element 8 for cleaning operations.

The feature examples provided in the disclosure of the present application are intended for illustrative purposes only and not for limitation, unless otherwise expressly stated. In specific implementations, multiple features can be combined with each other according to actual needs and when technically feasible.
