Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to an oil cup device, a range hood and a control method. Background Art

[0002] At present, all buildings are equipped with range hoods to extract the fumes generated during cooking. When the range hood is working, the grease in the smoke will fall into the range hood, so the range hood is generally equipped with an oil cup to collect the dripping grease. However, the grease will cool and solidify after falling into the oil cup, making it very inconvenient to clean the oil cup. Therefore, some products set consumables in the oil cup to solve the problem of the inconvenience of cleaning the oil cup.

[0003] The patent with application number 202221280419.3 discloses an oil cup device provided with consumables, the oil cup device includes a cup body, a consumable assembly and a driving mechanism, an oil collecting chamber with an upper opening is formed in the cup body, the consumable assembly includes multiple groups of oil absorbing materials compatible with the oil collecting chamber, the driving mechanism is transmission-connected to the consumable assembly, and is used to drive the oil absorbing material in the oil collecting chamber out of the oil collecting chamber, and drive a group of the oil absorbing materials in the consumable assembly into the oil collecting chamber. During use, when the user estimates that the oil absorbing material in the cup body can no longer effectively absorb grease, the oil absorbing material in the oil collecting chamber can be driven to move to the outside of the oil collecting chamber by controlling the driving mechanism, and at the same time the driving mechanism delivers new oil absorbing material to the oil collecting chamber, thus solving the problem of difficult cleaning of traditional oil cups.

[0004] However, in actual use of this type of oil cup, since the saturation degree of oil absorption by the oil-absorbing material is difficult to accurately estimate, the user needs to frequently disassemble the oil cup and observe the saturation of the oil-absorbing material inside it to avoid waste of resources caused by premature replacement of the oil-absorbing material, or failure to replace the oil-absorbing material in time, resulting in excessive accumulation of oil in the oil cup. On this basis, the user also needs to adjust the drive mechanism accordingly to achieve the replacement of old and new oil-absorbing materials. In addition, when all the oil-absorbing materials in the consumable component are saturated, the user needs to manually disassemble the oil cup device and replace the consumable component. It can be seen that there are technical problems of low convenience and intelligence, which need to be further improved to enhance the user experience. Summary of the invention

DETAILED DESCRIPTION

[0039] The present application will be further described below in the form of specific embodiments. Those of ordinary skill in the art will be able to implement the present application based on these descriptions. In addition, the embodiments of the present application involved in the following description are generally only embodiments of a part of the present application, rather than all embodiments. Therefore, based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work should fall within the scope of protection of the present application.

[0040] Example 1

[0041] This embodiment discloses an oil cup device, which includes:

[0042] The oil collecting module 100 includes a trough body 110 for collecting oil droplets, wherein the trough body 110 includes an inclined bottom surface and an upper wall corresponding to the bottom surface, wherein the upper wall is formed with an opening for collecting dripping oil droplets. The trough body 110 also includes an inlet wall and an outlet wall correspondingly arranged on opposite sides of the bottom surface. The horizontal height of the bottom surface near one end of the inlet wall is lower than the horizontal height of the bottom surface near one end of the outlet wall. The trough body 110 in this embodiment is arranged with an inclined bottom surface, which is conducive to the natural flow of oil droplets along the inclined surface, ensuring that the oil droplets can be smoothly collected to one side of the inlet wall for subsequent centralized processing. The oil collecting module 100 also includes an installation unit 120 correspondingly arranged on the inlet wall and the outlet wall, wherein the installation unit 120 includes a group of installation walls 121 correspondingly extending outward from the side wall of the trough body 110, and the installation wall 121 is provided with an installation groove 122 at one end away from the trough body 110.

[0043] The consumables module 200 includes an oil absorbing material 210 adapted to the tank body 110, and a first roller 220 and a second roller 230 respectively hinged to the mounting units 120 on both sides of the tank body 110; the oil absorbing material 210 is arranged through the tank body 110, and its two ends are respectively wound on the first roller 220 and the second roller 230. Correspondingly, the inlet wall and the outlet wall are respectively provided with an input port and an output port for the oil absorbing material 210 to pass through. Adhesive layers 211 are provided at both ends of the oil absorbing material 210, and the adhesive layers 211 are bonded to the surfaces of the first roller 220 and the second roller 230. In this embodiment, the oil cup device also includes a driving module 300 connected to the consumables module 200, which is used to drive the oil absorbing material 210 to move from the first roller 220 to the second roller 230 along the bottom of the tank body, so as to realize the replacement of the oil absorbing material 210 inside the tank body 110. In actual use, driven by the driving module 300, the oil absorbing material 210 is released from the first roller 220, enters the tank body 110 from the input port, and absorbs the grease dripping into the tank body 110 or collected on the bottom of the tank body 110. Then, when the oil absorbing material 210 reaches the adsorption saturation state, it is discharged from the tank body 110 from the output port and wound on the second roller 230.

[0044] Furthermore, in order to allow the oil absorbing material 210 to effectively absorb the oil droplets collected inside the tank body 110, especially on the side of the tank body bottom surface close to the inlet wall, a limiting component 111 for controlling the relative distance between the oil absorbing material 210 and the bottom surface is further provided in this embodiment, and the limiting component 111 is provided in the oil droplet collection area. In this embodiment, by providing the lower end of the bottom surface at the side close to the inlet wall, and providing the limiting component 111 at this position, the oil absorbing material 210 newly entering the tank body 110 can immediately contact the oil droplets collected at the lower end of the bottom surface, thereby quickly starting the adsorption process and improving the adsorption efficiency.

[0045] The first roller shaft 220 is provided with protruding rods 221 at both ends thereof for being hinged to the mounting groove 122. In order to facilitate the installation of the first roller shaft 220, the mounting groove 122 in this embodiment is provided with a mounting notch, so that the first roller shaft 220 can be installed by simply pressing the protruding rods 221 on both sides of the first roller shaft 220 into the mounting groove 122 through the mounting notch, which is highly convenient to use. Furthermore, in order to avoid the problem of the protruding rod 221 being dragged and embedded due to the shaking of the first roller shaft 220 back and forth, the first roller shaft 220 in this embodiment is also provided with a stopper 222 for abutting against the surface of the mounting wall 121, and the stopper 222 is connected to the protruding rod 221.

[0046] In order to simplify the structural design of the device, the driving module 300 in this embodiment includes a winding motor 310, and the output end of the winding motor 310 passes through the mounting groove 122 and is connected to one end of the second roller 230. The other end of the second roller 230 is hinged to the mounting groove 122 through a rotating shaft 231; an elastic member 232 is also sleeved on the rotating shaft 231, and the two ends of the elastic member 232 are respectively abutted against the second roller 230 and the mounting wall 121. By directly connecting the output end of the winding motor 310 to the second roller 230, the need for additional transmission components is reduced, thereby simplifying the overall structure. Furthermore, by providing the elastic member 232, a close connection can be established between the winding motor 310 and the second roller 230, which not only improves the transmission effect, but also makes the connection between the two more stable. In addition, this design is also easy to disassemble and install, making it easier and faster to replace the second roller 230 or perform routine maintenance.

[0047] In order to effectively prevent the oil droplets on the second roller 230 from being scattered into the surrounding environment during the rotation process, the oil cup device of this embodiment further includes a leak-proof module 800 for preventing the oil droplets on the second roller 230 from being dropped; the leak-proof module 800 is arranged on the installation wall 121 through a fixing component 810. The fixing component 810 includes a torsion spring 811, and the two ends of the torsion spring 811 are respectively connected to the leak-proof module 800 and the surface of the tank body 110. In this embodiment, the leak-proof module 800 is a support tray.

[0048] The oil cup device also includes a residual monitoring module 500 and a prompting module 600 which are connected to each other. The residual monitoring module 500 is used to detect the use of the oil absorbing material 210 to obtain residual information. Specifically, the residual monitoring module 500 includes a thickness measuring unit for monitoring the thickness of the oil absorbing material 210 on the first roller 220. The thickness measuring unit includes a first monitoring component slidably mounted on the mounting unit 120, and a second monitoring component cooperating with the first monitoring component to measure the thickness of the oil absorbing material 210 on the first roller 220. The first monitoring component includes a sliding rod 510 slidably connected to the mounting unit 120, and a lower pressing roller 520 for pressing the surface of the first roller 220 is installed on the upper end of the sliding rod 510 through a mounting frame 540; the second monitoring unit includes a proximity switch 530 arranged at the lower part of the sliding rod 510, which is used to monitor the distance between the lower end of the sliding rod 510 and the proximity switch 530. When the winding motor 310 drives the oil absorbing material 210 to be replaced, the amount of the oil absorbing material 210 on the first roller 220 is continuously reduced, and accordingly, the lower pressure roller 520 will drive the slide bar 510 to move downward, and then approach the proximity switch 530. The second monitoring unit can calculate the remaining amount of the oil absorbing material 210 on the first roller 220 by measuring the distance between the lower end of the slide bar 510 and the proximity switch 530. This embodiment provides a monitoring module for the remaining amount of the oil absorbing material by cleverly utilizing the pressing of the oil absorbing material 210 by the lower pressure roller 520. The prompt module 600 is used to issue a remaining amount alarm according to the remaining amount information. Therefore, during the use of the oil cup device of this embodiment, when the second monitoring unit detects that the distance between the lower end of the slide bar 510 and the proximity switch 530 reaches a threshold value, the prompt module 600 prompts the user that the remaining amount of the oil absorbing material 210 on the surface of the current first roller 220 is small and needs to be replaced.

[0049] This embodiment is also provided with a liquid level detection module 400 and a control module 700. The liquid level detection module 400 is arranged above the oil droplet collection area, and is used to detect the oil storage height inside the oil droplet collection area to obtain liquid level information. The control module 700 includes a first control unit and a second control unit; the first control unit is connected to the liquid level detection module 400 and the driving module 300, and is used to start the driving module 300 according to the liquid level information; the second control unit is connected to the remaining monitoring module 500 and the prompting module 600, and is used to start the prompting module 600 according to the remaining information to issue a remaining alarm.

[0050] In addition, this embodiment also discloses a range hood, which includes a range hood body 900 and the above-mentioned oil cup device. The structural design of the range hood body 900 is a conventional design and will not be repeated in this embodiment. The oil cup device groove body 110 is provided with a mounting slot for fixing the oil cup device on the range hood body 900.

[0051] Example 2

[0052] This embodiment discloses a control method for the oil cup device described in Embodiment 1, comprising the following steps:

[0053] The liquid level detection module 400 detects the oil storage height inside the tank body 110 to obtain liquid level information; the first control unit receives the liquid level information detected by the liquid level detection module 400, and when the liquid level information shows that the oil storage height inside the tank body 110 reaches a threshold, the driving module 300 is turned on to replace the oil absorbing material 210 inside the tank body 110.

[0054] The remaining amount monitoring module 500 detects the usage of the oil absorbing material 210 on the first roller 220 to obtain the remaining amount information; the second control unit receives the remaining amount information detected by the remaining amount monitoring module 500, and when the remaining amount information shows that the oil absorbing material 210 on the first roller 220 has reached the threshold, the prompt module 600 is turned on to issue a remaining amount alarm. When the remaining amount information shows that the oil absorbing material 210 on the first roller 220 has reached the usage threshold, and the liquid level information shows that the oil storage height inside the tank 110 has reached the threshold, the second control unit intercepts the start signal sent by the first control unit to the driving module 300, and prevents the driving module 300 from replacing the oil absorbing material 210 inside the tank 110.

[0055] This embodiment also discloses a replacement process of the oil absorbing material 210, which specifically includes the following steps: after the remaining alarm is prompted, the old first roller 220 is removed, and a new first roller 220 wrapped with the oil absorbing material 210 is installed in the installation groove 122; after the free end of the new oil absorbing material 210 is bonded to the end of the old oil absorbing material 210, the driving module 300 is turned on to drive the oil absorbing material 210 to be transferred from one side of the tank body 110 to the other side of the tank body 110, so as to replace the oil absorbing material 210 inside the tank body 110. When the oil absorbing material 210 inside the tank body 110 is replaced, the old second roller 230 is removed, and the free end of the new oil absorbing material 210 is bonded to the surface of the new second roller 230, and the replacement of the oil absorbing material 210 is completed.
