Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and specifically to a range hood. Background Technology

[0002] As a common kitchen appliance, the range hood mainly consists of a smoke collection chamber and a casing assembly. It draws in cooking fumes generated in the kitchen through the smoke inlet and then exhausts them outdoors through the smoke pipe, thus keeping the kitchen air clean. However, in actual use, as time goes on, grease and other components in the cooking fumes gradually adhere to the grease filter at the smoke inlet of the range hood, forming a buildup of grease.

[0003] To maintain the normal operation of a range hood, users need to frequently clean the grease filter. This is not only time-consuming and laborious but also significantly impacts the user experience. If not cleaned for a long time, the grease on the filter surface becomes increasingly complex, making it difficult to remove effectively with conventional cleaning methods. This leads to a continuous accumulation of grease, eventually causing oil to drip from the range hood onto the cooktop, severely disrupting the kitchen cooking environment. More importantly, the grease buildup on the filter can clog the smoke inlet gaps, significantly reducing the range hood's smoke extraction efficiency and directly affecting its performance, thus lowering its oil fume purification efficiency.

[0004] Therefore, given the current technical situation where grease gradually accumulates on the surface of the oil filter during the use of existing range hoods, making it difficult to clean effectively and ultimately affecting the performance of the range hood and the user experience, there is an urgent need to invent a range hood with an automatic oil filter cleaning function to solve the above-mentioned technical problems. Utility Model Content

[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0033] This embodiment provides a range hood, such as... Figures 1 to 4 As shown, the range hood includes a housing 100, inside which is a control panel (not shown) for controlling the operation of the range hood. The housing 100 also includes a smoke collection chamber 110 and an air outlet duct 120, which are connected. The smoke collection chamber 110 contains an oil filter 2 and an oil cup 3 located below the oil filter 2. The housing 100 has a smoke inlet 4 facing the oil filter 2 and a panel 1. The panel 1 is movably connected to the housing 100. When the range hood is in its first state, the panel 1 covers the smoke inlet 4 via a movable connection. When the range hood is in its second state, an opening is formed between the panel 1 and the smoke inlet 4 via a movable connection. In the first state, a cleaning component 200 is provided on the side of the panel 1 facing the oil filter 2. The cleaning component 200 is electrically connected to the control panel and is used to spray electrolyzed water onto the oil filter 2.

[0034] This invention features a cleaning component 200 installed on panel 1 and electrically connected to a control board. The control board can then control the cleaning component 200 to spray electrolyzed water onto the oil filter 2. Since the electrolyzed water is weakly alkaline, it can remove the oil stains adhering to the oil filter 2. The wastewater can then fall into the oil cup 3 below the oil filter 2, thus achieving automatic cleaning of the oil filter 2. This eliminates the need for manual cleaning by the user, improving the convenience of cleaning and preventing the accumulation of oil stains due to untimely cleaning, which could affect the performance of the range hood and the user experience.

[0035] In addition, the cleaning component 200 is located on the side of the panel 1 facing the oil filter 2. When the range hood is not being cleaned, the panel 1 can be placed over the smoke inlet 4, so that the cleaning component 200 is hidden inside the housing 100, thus achieving a hidden design of the cleaning component 200 without affecting the aesthetic appearance of the range hood.

[0036] It should be noted that in this embodiment, a glass plate 5 is also provided below the panel 1. One side of the panel 1 is hinged to the housing 100. When it is necessary to extract oil fumes and clean the oil filter, the panel 1 can be rotated open. When the range hood is not working (not extracting oil fumes and cleaning the oil filter), the panel 1 can be rotated in the opposite direction to cover the smoke inlet 4.

[0037] In a preferred embodiment, such as Figure 4 As shown, the cleaning assembly 200 includes a water storage bottle 210, an electrolysis unit 220, a water pump 230, and a water pipe 240. The water inlet of the water pump 230 is connected to the water storage bottle 210 through the electrolysis unit 220, and the water outlet of the water pump 230 is connected to the water pipe 240. The water pipe 240 is equipped with a nozzle 250.

[0038] Electrolysis unit 220 and water pump 230 are electrically connected to the control board, and electrolysis unit 220 is used to electrolyze water.

[0039] In this embodiment, the start and stop of the electrolysis unit 220 and the water pump 230 can be controlled by the control board. When the cleaning function of the range hood is activated, the water pump 230 draws water from the water storage bottle 210 and flows through the electrolysis unit 220. The electrolysis unit 220 electrolyzes the water to produce hydrogen ions and oxygen ions, making the water weakly alkaline. Then, it is sprayed from the nozzle 250 and sprayed on the surface of the oil filter 2 to rinse and clean the oil stains.

[0040] In a further preferred embodiment, panel 1 is provided with a bracket 260, and electrolysis unit 220 and / or water pump 230 are fixed to panel 1 by the bracket 260.

[0041] In a further preferred embodiment, the electrolysis unit 220 is equipped with a first sensor (not shown in the figure) connected to the control board. The first sensor can acquire water flow information, and the control board can issue a prompt signal based on the water flow information. In this embodiment, when abnormal situations occur, such as when the water in the storage bottle 210 is exhausted, or when the water pump 230 malfunctions and cannot pump water normally, resulting in a low water flow rate, a prompt signal can be issued to remind the user to add water in time or check for faults. The prompt signal can be an audible and visual signal, or a digital fault code, etc. The first sensor can specifically be a water level sensor, which can monitor whether there is water in the storage bottle 210. When there is water, the water pump 230 will pump water.

[0042] In a further preferred embodiment, the water storage bottle 210 is threadedly connected to the electrolysis unit 220, making the water storage bottle 210 and the electrolysis unit 220 detachably connected, which facilitates the user to disassemble and assemble the water storage bottle 210.

[0043] In a further preferred embodiment, the water pipe 240 extends along the width direction of the oil mesh 2, and there are multiple nozzles 250. The nozzles 250 are evenly spaced between the two ends of the water pipe 240 and all face the oil mesh 2.

[0044] In a further preferred embodiment, the nozzle 250 is located above the horizontal center line of the oil mesh 2;

[0045] Alternatively, the injection point of nozzle 250 may be located in the area above the horizontal center line of oil mesh 2.

[0046] In this embodiment, the nozzle 250 or the incident point of the nozzle 250 is set above the horizontal center line of the oil mesh 2, so that the water flow can flow from top to bottom to cover all or most of the area of ​​the oil mesh 2, making full use of the oil-dissolving effect of electrolyzed water and avoiding cleaning dead corners as much as possible.

[0047] In another preferred embodiment, the surface of the oil mesh 2 is coated with a hydrophilic coating, which is an easy-to-clean coating that makes it difficult for oil stains to adhere to the surface of the oil mesh 2, thereby making it easier for the oil stains adhering to the surface of the oil mesh 2 to be washed away by electrolytic water. Furthermore, the thickness of the hydrophilic coating ranges from 1 to 6 micrometers.

[0048] In another preferred embodiment, a second sensor (not shown in the figure) connected to the control board is provided in the smoke collection chamber 110 or the air outlet duct. The second sensor can acquire the oil fume concentration value and send it to the control board. The control board controls the start and stop of the cleaning component 200 according to the oil fume concentration value.

[0049] In this embodiment, the control board can control the start and stop of the cleaning component 200 according to the oil fume concentration value. Specifically, it can be set to control the cleaning component 200 to turn on when the oil fume concentration value is zero. More specifically, as an example, when the user selects a suitable working level to turn on the range hood to extract oil fumes, the second sensor starts to monitor the oil fume concentration data in real time. When the oil fume concentration value gradually decreases to zero and the duration exceeds 5 minutes, the control board controls the cleaning component 200 to start cleaning the oil filter 2.

[0050] Specifically, the second sensor can be an oil fume concentration sensor.

[0051] In this specification, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
