Description

Technical Field

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

[0002] Existing range hoods generally include a range hood body and an oil cup disposed below the range hood body. The oil cup is used to collect the oil in the range hood body, and the user needs to remove the oil cup to dump the oil. Specifically, the Chinese utility model patent "An oil cup installation structure for a range hood" with application number CN201821055443.0 (authorization announcement number CN208579370U) includes a housing and an oil cup. The oil cup is detachably disposed at the bottom of the housing through an installation assembly. The installation assembly includes a first positioning block, a second positioning block and an elastic member. The first positioning block is disposed at the bottom of the housing and has a first positioning portion at the lower end; the second positioning block is disposed on the inner wall of the oil cup and has a second positioning portion at the upper end; the elastic member enables the second positioning portion to always maintain a tendency to engage with the first positioning portion.

[0003] Another example is the Chinese utility model patent "A Range Hood" with application number CN201821529177.0 (authorization announcement is CN209026905U), which includes a shell and an oil cup. At least two slots extending in the front-to-back direction are arranged at intervals at the bottom of the shell. The oil cup is in the shape of a long strip and is installed at the bottom of the shell and extends in the left-to-right direction. The oil cup has a corresponding plug-in extending in the front-to-back direction and is plugged into the slot; the plug-in is located at a position with a certain distance from the left and right ends of the oil cup and is higher than the upper edge of the rear side of the oil cup.

[0004] If there is too much oil in the oil cup, there is a risk of oil spilling when the existing oil cup is removed to pour the oil, which affects the user experience. In addition, the oil cup needs to be removed every time the oil is poured, which is inconvenient. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide an oil cup assembly for a range hood which is convenient for oil discharge 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 having the above oil cup assembly.

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

[0008] The oil cup body comprises a bottom wall and a side wall extending upward from the periphery of the bottom wall, wherein the bottom wall and the side wall together form a concave cavity with an opening facing upward;

[0009] It is characterized by also including:

[0010] The oil drain pipe has a first oil drain section and a second oil drain section in its length direction, the first oil drain section and the second oil drain section are arranged in an inverted V shape, and the lower port of the first oil drain section is located inside the oil cup body as the oil inlet port of the oil drain pipe, and the lower port of the second oil drain section is located outside the oil cup body as the oil outlet port of the oil drain pipe, and the upper edge of the side wall of the oil cup body is inserted into the recess formed at the intersection of the first oil drain section and the second oil drain section, so that the oil drain pipe is supported on the side wall of the oil cup body.

[0011] When in use, the oil drain pipe is supported on the side wall of the oil cup body, and then the oil in the oil cup body can be sucked out through the oil drain pipe. It is convenient to use without removing the oil cup body. The inverted V-shaped oil drain pipe in the utility model can be stably supported on the side wall of the oil cup body, and it is easy to take out the oil drain pipe for cleaning.

[0012] Preferably, the edge of the oil inlet port of the oil drain pipe is disposed adjacent to or in contact with the bottom wall of the oil cup body, so that the oil at the bottom of the cup can also be discharged through the oil drain pipe.

[0013] Furthermore, the edge of the oil inlet port of the oil drain pipe fits the bottom wall of the oil cup body, and a notch is provided at the edge of the oil inlet port, so that the oil in the oil cup body can enter the oil drain pipe.

[0014] To improve the oil drainage effect, preferably, there are at least two notches, which are arranged at intervals along the circumferential direction.

[0015] Preferably, the inner diameter of the oil drain pipe is 3-10 mm; the upper edge of each notch is spaced apart from the bottom wall of the oil cup body, with a spacing height of 0.5-2 mm; the upper edge of each notch extends 2-4 mm in the circumferential direction.

[0016] Furthermore, the edge of the oil inlet port of the oil drain pipe is a magnetic body that can be magnetically attracted to the bottom wall of the oil cup body, so that the oil drain pipe can be more stably supported on the oil cup body and the oil inlet port of the oil drain pipe can always fit the bottom wall of the oil cup body.

[0017] In the above schemes, preferably, the first oil drainage section of the oil drainage pipe has a first part extending obliquely upward from the edge of the oil inlet port, a second part extending obliquely downward from the upper end of the first part, and a third part extending obliquely upward from the lower end of the second part, the upper end of the third part intersects with the upper end of the second oil drainage section, the second part and the first part are arranged in an inverted V shape, and the intersection of the two is located below the intersection of the upper end of the third part and the upper end of the second oil drainage section.

[0018] When the oil level in the oil cup is greater than the height of the upper end of the first part and less than the height of the upper end of the third part, the oil enters the first part of the oil drain pipe through the oil inlet port under the action of atmospheric pressure and hydraulic pressure, and after passing over the upper end of the first part, it accelerates downward to the lower end of the second part under the action of its own gravity, and the flow rate increases. Then, under the action of its own kinetic energy, it overcomes its own gravity and flows upward to the third part until it passes over the upper end of the third part, and finally flows out through the second oil drain section under the action of its own gravity to achieve oil drainage.

[0019] Preferably, the first portion of the oil drain pipe has an inclination angle of 30 to 60° relative to the horizontal plane; the second portion of the oil drain pipe has an inclination angle of 60 to 90° relative to the horizontal plane; and the third portion of the oil drain pipe has an inclination angle of 30 to 60° relative to the horizontal plane.

[0020] Preferably, the height difference between the intersection of the upper end of the third part and the upper end of the second oil-draining section and the lower end of the first part is ΔH, the height difference between the upper end of the first part and the lower end of the first part is ΔH1, the height difference between the upper end of the second part and the lower end of the second part is ΔH2, and the height difference between the upper end of the third part and the lower end of the third part is ΔH3, satisfying:

[0021] 1 / 4×△H≤△H1≤3 / 4×△H;

[0022] 1 / 4×△H≤△H2≤3 / 4×△H;

[0023] 1 / 4×△H≤△H3≤2 / 4×△H.

[0024] In this way, a sufficient height difference and angle are ensured, thereby ensuring that the kinetic energy generated when the oil flows downward in the second part is sufficient to climb through the upper end of the third part, thereby achieving automatic oil drainage.

[0025] Of course, in addition to the automatic oil drainage method, manual oil drainage can also be used, such as using the siphon principle to drain the oil.

[0026] Preferably, the inclination angle of the second oil discharge section of the oil discharge pipe relative to the horizontal plane is 30-90°; the lower end of the second oil discharge section is located below the bottom wall of the oil cup.

[0027] In the above schemes, in order to further improve the structural stability, preferably, the oil drain pipe is supported on the side wall of one of the left and right sides of the oil cup body, and is in contact with the side wall of one of the front and rear sides of the oil cup body.

[0028] Preferably, the upper edge of the side wall of at least one of the left and right sides of the oil cup body is folded and extended inward to form a folded edge, so that the oil cup body can be installed on the range hood, and the end of the folded edge is spaced and opposed to the corresponding side wall of at least one of the front and rear sides of the oil cup body to form a gap, so that the oil drain pipe can be restrained therein. In this way, the folded edge can not only install the oil cup body on the range hood, but also restrain the oil drain pipe to prevent the oil drain pipe from accidentally detaching from the oil cup body or preventing the oil drain pipe from moving forward and backward.

[0029] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, characterized by having the oil cup assembly as described above.

[0030] Compared with the prior art, the advantages of the utility model are: when in use, the oil drain pipe is supported on the side wall of the oil cup body, and then the oil in the oil cup body can be sucked out through the oil drain pipe, which is convenient for use without removing the oil cup body; and the inverted V-shaped oil drain pipe in the utility model can be stably supported on the side wall of the oil cup body, and it is easy to take the oil drain pipe for cleaning.

The above three parts are recorded as the first oil drain section 2a of the oil drain pipe 2. The oil drain pipe 2 also has a second oil drain section 2b extending obliquely downward from the upper end of the third part 23, and the lower end of the second oil drain section 2b is the oil outlet port 202 of the oil drain pipe 2. The second oil drainage section 2b and the third part 22 are arranged in an inverted V shape, and a notch 20 is formed at the intersection of the two, so that the upper edge of the side wall 12 of the oil cup body 1 can be inserted therein. In this embodiment, the oil drain pipe 2 is supported on the side wall 12 on one of the left and right sides of the oil cup body 1, and is located in the corresponding gap 130, and is in contact with the side wall on the front side of the oil cup body 1. The oil inlet port 201 of the oil drain pipe 2 is located inside the oil cup body 1, and the oil outlet port 202 of the oil drain pipe 2 is located outside the oil cup body 1 and below the bottom wall 11 of the oil cup. The second part 22 and the first part 21 are arranged in an inverted V shape, and the intersection of the two is located below the intersection of the upper end of the third part 23 and the upper end of the second oil drainage section 2b. In this embodiment, as Figure 4 As shown, the inclination angle a1 of the first portion 21 of the oil discharge pipe 2 relative to the horizontal plane is 30-60° (a1 can be any value between 30-60°, such as a1 is 30°, 40°, 60°, etc.), the inclination angle a2 of the second portion 22 relative to the horizontal plane is 60-90° (a2 can be any value between 60-90°, such as a2 is 60°, 80°, 90°, etc.), the inclination angle a3 of the third portion 23 relative to the horizontal plane is 30-60° (a3 can be any value between 30-60°, such as a3 is 30°, 40°, 50°, 60°, etc.), and the inclination angle a4 of the second oil discharge section 2b relative to the horizontal plane is 30-90° (a4 can be any value between 30-90°, such as a4 is 30°, 40°, 60°, 90°, etc.). The height difference between the upper end of the third part 23 and the junction of the upper end of the second oil discharge section 2b and the lower end of the first part 21 is △H, the height difference between the upper end of the first part 21 and the lower end of the first part 21 is △H1, the height difference between the upper end of the second part 22 and the lower end of the second part 22 is △H2, and the height difference between the upper end of the third part 23 and the lower end of the third part 23 is △H3, which satisfies:

[0040] 1 / 4×△H≤△H1≤3 / 4×△H;

[0041] 1 / 4×△H≤△H2≤3 / 4×△H;

[0042] 1 / 4×△H≤△H3≤2 / 4×△H;

[0043] △H2<△H1.

[0044] At the same time, if Figure 4 , 5 As shown, the edge of the oil inlet port 201 of the oil drain pipe 2 of this embodiment is arranged in contact with the bottom wall 11 of the oil cup body 1, and the edge of the oil inlet port 201 is provided with a notch 203, and there are two notches 203, which are arranged at equal intervals along the circumferential direction. In addition, the inner diameter of the oil drain pipe 2 is 3 to 10 mm (the inner diameter can be any value between 3 and 10 mm, such as 3 mm, 5 mm, 10 mm, etc.); the upper edge of each notch 203 is spaced opposite to the bottom wall 11 of the oil cup body 1, and the spacing height is 0.5 to 2 mm (the spacing height can be any value between 0.5 and 2 mm, such as 0.5 mm, 1 mm, 2 mm, etc.); the upper edge of each notch 203 extends in the circumferential direction for 2 to 4 mm (the extension length can be any value between 2 and 4 mm, such as 2 mm, 3 mm, 4 mm, etc.). At the same time, the edge of the oil inlet port 201 of the oil drain pipe 2 is a magnetic body that can be magnetically attracted to the bottom wall 11 of the oil cup body 1 , so that the edge of the oil inlet port 201 can always fit the bottom wall 11 of the oil cup body 1 .

[0045] The range hood of this embodiment includes a range hood body 3 and the above-mentioned oil cup assembly. The oil cup body 1 is arranged below the range hood body 3 and is constrained together with the range hood body 3 by a folded edge 13. The connection structure between the folded edge 13 and the range hood body 3 is designed with reference to the prior art and will not be elaborated here.

[0046] When placing the oil drain pipe 2, the user only needs to place the portion where the notch 20 is located on the side wall 12 of the oil cup body 1, place the oil inlet port 201 inside the oil cup body 1, and suck it onto the bottom wall 11 of the oil cup body 1. The side of the oil drain pipe 2 is naturally attached to the side wall 12 on the front side of the oil cup body 1, and the oil drain pipe is placed.

[0047] When the oil level in the oil cup body 1 is greater than the height of the upper end of the first part 21 and less than the height of the upper end of the third part 23, the oil enters the first part 21 of the oil drain pipe 2 through the oil inlet port 201 under the action of atmospheric pressure and hydraulic pressure, and after passing the upper end of the first part 21, the oil accelerates downward to the lower end of the second part 22 under the action of its own gravity, and the flow rate is accelerated, and then under the action of its own kinetic energy, it overcomes its own gravity and flows upward to the third part 23 until it passes the upper end of the third part 23, and finally flows out through the second oil drain section 2b under the action of its own gravity, and then maintains a siphon state under the action of the cohesive force of the oil to achieve automatic oil drainage. After the oil is drained, the user can remove the oil drain pipe 2 for cleaning. And in order to improve the oil drainage efficiency, the user can simultaneously place two oil drain pipes 2 on both sides of the oil cup body 1, one on the left and one on the right.
