Description

Technical Field

[0001] The present invention relates to the technical field of kitchen range hoods, and particularly to an oil cup structure with an oil removal function and a range hood. Background Art

[0002] With the progress of society and the improvement of people's living standards, range hoods are widely used in people's daily lives. Traditional range hoods are generally equipped with an oil cup for collecting oil stains. The following problems exist in the actual use process: Currently, range hoods are all installed at a certain height. When replacing or cleaning the oil cup, one needs to raise both hands high or even look up at the oil cup to take out the oil cup for replacement. Some customers even need to stand on tiptoe to complete this operation. This operation may cause waste oil to overflow from the oil cup. Some short customers also need to use a stool to assist in the replacement, which poses a safety hazard; and the recycled oil in the oil cup will solidify after a period of time, increasing the difficulty of cleaning. Summary of the Invention

[0003] The purpose of the present invention is to provide an oil cup structure with an oil removal function and a range hood to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] First, the present invention provides an oil cup structure with an oil removal function, which includes: an oil cup body, a heating mechanism, and an oil pumping mechanism. The oil cup body is provided with an oil collecting groove with an upward opening; the heating mechanism is used to heat and soften the oil collected in the oil collecting groove; the oil pumping mechanism includes an oil pumping power device, and the oil pumping power device has an oil inlet end and an oil outlet end, and the oil inlet end is communicated with the oil collecting groove.

[0006] The beneficial effect of the present invention is: When in use, the oil collected in the oil collecting groove is heated and softened by the heating mechanism, and then the softened oil in the oil collecting groove is pumped out by the oil pumping power device, realizing automatic oil removal of the oil cup body without disassembling the oil cup body. The heating of the heating mechanism can effectively prevent the accumulated oil in the oil collecting groove from solidifying due to long time and being inconvenient to clean, reducing the cleaning difficulty. The oil pumping power device can make the accumulated oil be quickly and completely discharged, improving the cleaning effect.

[0007] As a further improvement of the above technical solution, the oil pumping power device includes an oil pump. The inlet of the oil pump is connected with an oil suction pipe, and the outlet of the oil pump is connected with an oil discharge pipe. The oil suction pipe extends into the oil collecting groove.

[0008] In this solution, the accumulated oil in the oil collecting groove is pumped out by the oil pump. When in use, the inlet of the oil suction pipe extends into the bottom of the oil collecting groove, and the accumulated oil is discharged from the oil discharge pipe. According to different requirements, the oil discharge pipe can be connected to an external recycled oil container.

[0009] As a further improvement of the above technical solution, the oil cup structure also includes a lifting mechanism, which is provided with a lifting drive end that is transmission-connected to the heating mechanism and enables the heating mechanism to extend into or out of the oil collecting tank relative to the oil cup body.

[0010] When oil removal is required, the lifting drive end on the lifting mechanism drives the heating mechanism to extend into the oil collecting tank. At this time, the heating mechanism can start to heat and soften the collected oil in the oil collecting tank, avoiding the heating mechanism from being immersed in the oil collecting tank all the time, preventing the heating mechanism from leaking electricity, reducing safety hazards, and also extending the service life of the heating mechanism.

[0011] As a further improvement of the above technical solution, the lifting mechanism includes a guide frame, a lifting frame, and a lifting drive device. The guide frame is fixedly arranged relative to the oil cup body, the lifting frame is arranged on the guide frame, the lifting drive device can drive the lifting frame to move up and down relative to the guide frame, and the heating mechanism is installed on the lifting frame.

[0012] In this solution, the lifting frame is driven to move up and down relative to the guide frame by the lifting drive device, thereby driving the heating mechanism on the lifting frame to move up and down above the oil collecting tank.

[0013] As a further improvement of the above technical solution, the heating mechanism includes a heating pipe, and the heating pipe extends along the direction in which the oil collecting tank extends. In this solution, the accumulated oil in the oil collecting tank is heated by the heating pipe. During heating, the heating pipe can be immersed in the oil collecting tank. In other solutions, the heating pipe can be close to the oil collecting tank.

[0014] As a further improvement of the above technical solution, the oil pumping mechanism is installed on a lifting frame.

[0015] At the same time, the lifting frame can also drive the oil pumping mechanism to move up and down to prevent solidified accumulated oil from clogging the oil inlet end.

[0016] As a further improvement of the above technical solution, the heating mechanism includes a heating wire attached to the wall surface of the oil cup body. In this solution, the accumulated oil in the oil cup body is heated by the heating wire, wherein the heating wire can be arranged on the inner wall or the outer wall of the oil cup body.

[0017] As a further improvement of the above technical solution, the oil cup structure also includes a sensor assembly and a controller. The controller is electrically connected to the sensor assembly, the heating mechanism and the oil pumping power unit at the same time. The sensor assembly is used to detect the amount of oil collected in the oil collecting tank. The controller is configured to control the start and stop of the heating mechanism and the oil pumping power unit after receiving the signal transmitted by the sensor assembly.

[0018] This solution detects the amount of oil collected in the oil collecting tank in real time through the sensor assembly. When the amount of oil collected in the oil collecting tank reaches the set value, the controller controls the heating mechanism and the oil pumping power device to start, realizing automatic oil removal.

[0019] As a further improvement of the above technical solution, the sensor assembly is one of a liquid level sensor or a weight sensor.

[0020] The oil surface height of the accumulated oil in the oil collecting tank can be detected by a liquid level sensor, or the weight of the accumulated oil in the oil collecting tank can be detected by a weight sensor.

[0021] In addition, the present invention also provides an oil fume extractor, which includes the above oil cup structure and the main body of the range hood. A fume collection cavity is arranged in the main body of the range hood, the oil cup body is arranged at the bottom of the fume collection cavity, the fume collection cavity is communicated with the oil collecting tank, and the heating mechanism and the oil pumping power device are arranged in the cavity formed by the fume collection cavity and the oil collecting tank.

[0022] When the oil fume extractor is operating, the accumulated oil in the fume collection cavity converges into the oil collecting tank, and only the accumulated oil in the oil collecting tank needs to be removed. At the same time, the heating mechanism and the oil pumping power device are hidden and installed in the main body of the range hood, which can enhance the aesthetic appearance of the oil fume extractor.

[0032] Referring to Figures 1 to 2 , the following embodiments are made for the range hood of the present invention:

[0033] The range hood of this embodiment includes a range hood main body 700 and an oil cup structure. The oil cup structure includes an oil cup body 100, a heating mechanism, and an oil pumping mechanism. The oil cup body 100 is provided with an oil collecting groove 110 with an upward opening. An oil fume collecting cavity is arranged in the range hood main body 700. The oil cup body 100 is detachably installed at the bottom of the oil fume collecting cavity. The oil fume collecting cavity is communicated with the oil collecting groove 110. In some other embodiments, the oil cup body 100 and the range hood main body 700 can be integrated. The heating mechanism in this embodiment is used to heat and soften the oil collected in the oil collecting groove 110. Since the collected oil will solidify after a period of time, it is necessary to heat the oil collected in the oil collecting groove 110 before it can be discharged. Specifically: the heating mechanism is a heating tube 500. When heating, the heating tube 500 extends into the oil collecting groove 110, and the heating tube 500 extends along the extending direction of the oil collecting groove 110, which can expand the heating range. The oil pumping mechanism includes an oil pumping power device. The oil pumping power device has an oil inlet end and an oil outlet end. The oil inlet end is communicated with the oil collecting groove 110. The oil pumping power device is mainly used to pump out the oil collected in the oil collecting groove 110. The oil pumping power device in this embodiment includes an oil pump 200. The inlet of the oil pump 200 is connected with an oil suction pipe 210. The outlet of the oil pump 200 is connected with a drain pipe 220. The oil suction pipe 210 extends into the oil collecting groove 110. When in use, the inlet of the oil suction pipe 210 extends into the bottom of the oil collecting groove 110. The accumulated oil softened by heating is discharged from the drain pipe 220 through the pumping of the oil pump 200. According to different requirements, the drain pipe 220 can be connected to an externally provided oil recovery container.

[0034] This embodiment realizes the automatic recovery of the accumulated oil in the oil cup body 100 without disassembling the oil cup body 100. The heating of the heating mechanism can effectively prevent the accumulated oil in the oil collecting tank 110 from solidifying due to long time and being inconvenient to clean, reducing the cleaning difficulty. The oil pumping power device can quickly and completely drain the accumulated oil, improving the cleaning effect.

[0035] Further, the oil cup structure further includes a lifting mechanism installed on the main body 700 of the range hood. The lifting mechanism is mainly used to drive the heating pipe 500 to extend into or out of the oil collecting tank 110, avoiding the heating pipe 500 being immersed in the oil collecting tank 110 all the time, preventing the heating pipe 500 from leaking electricity, reducing potential safety hazards, and at the same time prolonging the service life of the heating pipe 500. Specifically: The lifting mechanism includes a guiding frame 300, a lifting frame 400, and a lifting driving device. The guiding frame 300 is fixedly arranged relative to the oil cup body 100. In this embodiment, the guiding frame 300 is fixed on the main body 700 of the range hood. The lifting frame 400 is slidably installed on the guiding frame 300. The lifting driving device can drive the lifting frame 400 to move up and down relative to the guiding frame 300. The lifting driving device can be a linear driving unit such as an electric push. The heating pipe 500 is installed at the lower part of the lifting frame 400. When oil removal is required, the lifting driving device drives the lifting frame 400 to move up and down relative to the guiding frame 300, so as to drive the heating pipe 500 to extend downward into the oil collecting tank 110. At this time, the heating pipe 500 starts to heat and soften the accumulated oil in the oil collecting tank 110.

[0036] At the same time, in order to prevent the solidified accumulated oil from blocking the oil suction pipe 210, the oil pump 200 is also installed on the lifting frame 400, and the oil suction pipe 210 can move up and down with the oil pump 200.

[0037] To enhance the aesthetic appearance of the range hood, the heating mechanism and the oil pumping power device are hiddenly installed in the main body 700 of the range hood, that is, the oil pump 200 and the heating pipe 500 are hiddenly installed in the main body 700 of the range hood.

[0038] The oil cup structure in this embodiment further includes a sensor assembly and a controller. The controller is electrically connected to the sensor assembly, the heating mechanism, and the oil pumping power device at the same time. The sensor assembly is used to detect the amount of accumulated oil in the oil collecting tank 110. The controller is configured to control the start and stop of the heating mechanism and the oil pumping power device after receiving the signal transmitted by the sensor assembly. The sensor assembly is one of a liquid level sensor or a weight sensor. The liquid level sensor is used to detect the oil level height of the accumulated oil in the oil collecting tank 110, or the weight sensor is used to detect the weight of the accumulated oil in the oil collecting tank 110. When the amount of accumulated oil in the oil collecting tank 110 reaches the set value, the controller controls the oil pump 200 and the heating pipe 500 to start, realizing automatic oil removal.

[0039] If the above-mentioned lifting mechanism is installed, the controller controls the lifting of the lifting mechanism. During oil removal, the controller controls the lifting mechanism to drive the oil pump 200 and the heating pipe 500 to move downward. The heating pipe 500 is extended into the oil sump 110 before starting the heating pipe 500 for heating. After heating for a certain period of time, the oil pump 200 is started. After the oil pumping is completed, the heating pipe 500 and the oil pump 200 are stopped, and the controller controls the lifting mechanism to drive the oil pump 200 and the heating pipe 500 to reset.

[0040] In some embodiments, the range hood can record time. After the range hood is used for a period of time, it will automatically perform a cleaning function or prompt the user to perform cleaning.

[0041] In some embodiments, the heating pipe 500 does not need to extend into the oil sump 110. The heating pipe 500 can be arranged beside the oil sump 110, which can also realize heating and softening of the accumulated oil in the oil sump 110.

[0042] In some embodiments, the lifting mechanism can drive the oil pump 200 and / or the heating pipe 500 to move in other directions. In this embodiment, the movement is limited to the up and down direction. In some other embodiments, it can move obliquely, as long as the heating pipe 500 or the oil pipe 210 can be pulled out of or extended into the oil sump 110.

[0043] In some embodiments, the heating pipe 500 can be replaced with other heating elements, such as an electric heating wire 600. As for the installation position of the electric heating wire 600, there are various options, such as Figure 3 shown, the electric heating wire 600 is arranged on the inner wall of the oil cup body 100, as Figure 4 shown, the electric heating wire 600 can also be arranged on the outer wall of the oil cup body 100.

[0044] The above has specifically described the preferred embodiments of the present invention. However, the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
