[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0033] The following is for reference. Figures 1-7 Description of a range hood 1 according to an embodiment of the present utility model.
[0034] The range hood 1 according to this application includes a housing 11, a baffle 12, and an oil scraping device 13. A suction chamber 111 is formed inside the housing 11, and a suction port 112 communicating with the suction chamber 111 is formed at the bottom of the housing 11. Airflow can enter the suction chamber 111 through the suction port 112 and thus enter the interior of the range hood 1. The baffle 12 is housed within the suction chamber 111, positioned above the suction port 112, and spaced a certain distance from the suction port 112. The projection of the baffle 12 onto the bottom of the housing 11 at least covers the portion of the suction port 112 directly opposite the top plate of the housing 11. The oil scraping device 13 is disposed inside the suction chamber 111, and an oil scraping element 133 is formed on the oil scraping device 13 that contacts the bottom surface of the baffle 12. The oil scraping device 13 can move within the suction chamber 111 to scrape the bottom surface of the baffle 12 using the oil scraping element 133.
[0035] In some embodiments, during the process of absorbing cooking fumes, some of the fumes may adhere to the top plate of the housing 11, making it difficult to remove the oil stains. The accumulation inside the top plate may affect the appearance of oil stains on the outer surface of the housing 11. To address this, embodiments of this application include a baffle 12, which can be used to block cooking fumes directed towards the inner top plate of the housing 11 to prevent the formation of oil stains on the top plate of the housing 11. However, while blocking the cooking fumes, the baffle 12 also forms oil stains at its bottom, which pose a risk of dripping. This oil stains may drip from the air intake 112 out of the housing 11, causing contamination of the cooking countertop.
[0036] According to one embodiment of the present application, a range hood 1 has a movable oil scraping device 13 at the bottom of the baffle 12 for cleaning the bottom of the baffle 12, preventing the accumulation of oil stains at the bottom of the baffle 12, and avoiding oil stains dripping onto the cooking countertop. In this embodiment, the oil scraping device 13 includes an oil scraping member 133 that contacts the baffle 12. While maintaining contact with the bottom surface of the baffle 12, the oil scraping member 133 moves to scrape away oil stains from the bottom of the baffle 12, preventing oil stains from accumulating at the bottom of the baffle 12 and thus avoiding oil stains dripping.
[0037] The oil scraping device 13 can be mounted on the baffle 12 to maintain stable contact between the oil scraping device 13 and the baffle 12, ensuring effective oil scraping. Of course, in other embodiments, the movement of the oil scraping device 13 may not depend on the baffle 12; the oil scraping device 13 can move relative to the housing 11 or be mounted on other components fixed relative to the housing 11. It should be understood that the form of movement of the oil scraping device 13 relative to the housing 11 is not a limitation on the oil scraping device 13 in this application.
[0038] According to the range hood 1 of this application, a baffle 12 is provided inside the suction chamber 111 to prevent oil stains from adhering to the top plate of the housing 11. Simultaneously, an oil scraping device 13 is provided to scrape away oil stains at the bottom of the baffle 12, preventing oil fume accumulation at the bottom of the baffle 12. During use, the range hood 1 of this application prevents oil stains from easily accumulating inside the housing 11 and prevents oil stains from easily appearing on the outer surface, maintaining cleanliness for a long time. Oil stains do not easily accumulate at the bottom of the baffle 12, and oil stains do not easily drip from the suction port 112.
[0039] According to some embodiments of this application, an oil-scraping device 13 has an oil storage cavity 131 inside, and an oil collection port 132 is provided on the top of the oil storage cavity 131. The oil collection port 132 is located on one side of the oil scraping member 133 in the moving direction of the oil scraping device 13. In this embodiment, by forming an oil storage cavity 131 inside the oil scraping device 13 and providing an oil collection port 132 on the top of the oil storage cavity 131, the oil scraping device 13 collects oil in the oil storage cavity 131 during the oil scraping process, preventing oil from dripping during the scraping of oil from the bottom of the baffle 12, thus keeping the cooking countertop clean. The oil collection port 132 of the oil scraping device 13 is located on one side in the moving direction of the oil scraping member 133. This can be understood as the oil flowing along the oil scraping member 133 to the oil collection port 132 and being collected in the oil storage cavity 131 during the contact between the oil scraping member 133 and the bottom surface of the baffle 12.
[0040] In some embodiments, the oil scraper 133 may be configured as a strip to increase the oil scraping area, and the oil collection port 132 is correspondingly configured as a strip-shaped hole extending in the width direction of the oil scraper 13.
[0041] In some embodiments, the oil scraping device 13 can scrape oil in a unidirectional direction and reset during reverse movement. In this embodiment, the oil collection port 132 and the oil scraper 133 are configured as one or more corresponding components. In other embodiments, the oil scraping device 13 can scrape oil in a bidirectional direction, and the oil collection port 132 can be provided on both sides of the oil scraper 133 to ensure that the oil scraping device 13 can collect oil during bidirectional movement and prevent oil dripping.
[0042] The oil scraper 133 can be configured as a flexible scraper. The flexible scraper can scrape off the oil stains at the bottom of the baffle 12 during the contact process with the bottom of the baffle 12, and the scraping efficiency is high.
[0043] According to some embodiments of this application, the oil scraping device 13 includes an oil storage shell 134, which is movably disposed at the bottom of the baffle 12. An oil storage cavity 131 is defined inside the oil storage shell 134, and an oil collection port 132 extending in the width direction of the baffle 12 is formed on the top of the oil storage shell 134. An oil scraper 133 is disposed on the top of the oil storage shell 134, and the oil scraper 133 extends from at least a portion of the edge of the oil collection port 132 toward the baffle 12 and abuts against the baffle 12.
[0044] The oil storage shell 134 serves as the main structure of the oil scraping device 13. The oil storage cavity 131 formed inside is used to collect oil. The oil scraping element 133 is located on the top of the oil storage shell 134 and can move stably with the oil storage shell 134 to ensure the stability of the oil scraping process. The oil scraping element 133 is located on at least part of the edge of the oil collection port 132 to ensure that the scraped oil flows along the surface of the oil scraping element 133 to the oil collection port 132 and is collected in the oil storage cavity 131.
[0045] According to some embodiments of this application, the oil storage shell 134 is constructed as a cylindrical shell 11 extending in the width direction of the baffle 12, with one end of the oil storage shell 134 open toward the side wall of the suction chamber 111.
[0046] According to some embodiments of this application, the range hood 1 further includes a driving component, which has a driving end connected to the oil scraping device 13. The driving component is adapted to drive the oil scraping device 13 to move along the bottom surface of the baffle 12. The driving component can be a mechanism capable of outputting power, such as a motor, cylinder, air pump, etc. The driving end can output power or move directly under the action of the driving component. The driving end is connected to the oil scraping device 13 to drive the oil scraping device 13 to move, thereby scraping off the oil stains on the bottom surface of the baffle 12. The driving component can also be a component for transmitting power, which does not have the ability to drive itself. The driving end of the driving component is used for movement, and the driving component can move under the action of an external power source to drive the oil scraping device 13 to move.
[0047] By setting a driving component, the oil scraping device 13 can be driven to perform oil scraping operations, providing power for the movement of the oil scraping device 13. The driving component can be powered by its own power source or can utilize an external power source from the range hood 1.
[0048] In some embodiments of this application, the range hood 1 further includes a first support member 141 and a second support member 142. The first support member 141 is disposed in the air intake cavity 111 and located in front of the baffle 12. A first support point is provided on the first support member 141, and the first support point is connected to the oil scraping device 13. The second support member 142 is disposed in the air intake cavity 111 and located in rear of the baffle 12. A second support point is provided on the second support member 142. The oil scraping device 13 is provided with a connection point 1341 connected to the driving member. The connection point 1341 is located at the bottom of the first support point and the second support point. The driving end of the driving member is connected to the connection point 1341 by a pull rope 162 that passes around the second support point.
[0049] The first support member 141 is used to fix the front side of the oil scraping device 13. The connection between the oil scraping device 13 and the first support member 141 generates a forward force on the oil scraping device 13 toward the first support point. The second support point provided on the second support member 142 is used to bypass the pull rope 162. The pull rope 162 is directly connected to the connection point 1341. The pull rope 162 generates a force on the oil scraping device 13 from the connection point 1341 toward the rear of the second support point. Setting the connection point 1341 at the bottom of the line connecting the first connection point 1341 and the second connection point 1341 allows the resultant force of the forward and rearward forces on the oil scraping device 13 to be directed toward the baffle 12, making the oil scraping device 13 close to the bottom of the baffle 12, thereby ensuring that the oil stains at the bottom of the baffle 12 are scraped off during the movement of the oil scraping device 13.
[0050] Furthermore, the front and rear forces act and react with each other, ensuring the stability of the oil scraping device 13 during movement.
[0051] According to one embodiment of this application, the bottom wall of the housing 11 is inclined towards the bottom in the direction from front to back, and an oil guide groove 151 is formed on the rear edge of the bottom wall of the housing 11. A pull ring hole 152 is formed on the bottom wall of the housing 11 located in the oil guide groove 151. The drive end is constructed as a pull ring 161. The pull ring 161 is engaged with the pull ring hole 152 and connected to the pull rope 162 to drive the oil scraping device 13 to move along the bottom surface of the baffle 12.
[0052] In this embodiment, by setting the bottom wall of the housing 11 to be inclined towards the bottom in the direction from front to back, the oil stains collected on the bottom wall of the housing 11 can flow towards the rear and eventually collect in the oil guide groove 151. The range hood 1 may also include an oil collection cup, which can be located below the oil guide groove 151 and used to collect the oil in the oil guide groove 151.
[0053] In the above embodiment, the driving component adopts an external power source, which is transmitted to the oil scraping device 13 through the pull rope 162. The driving end is constructed as a pull ring 161 for the user to pull. The pull ring 161 fits in the pull ring hole 152, so that the pull ring 161 can be hidden in the oil collection cup. When not in use, the pull ring 161 can be hidden. When it is necessary to scrape the oil stains off the bottom of the baffle 12, the oil collection cup is removed and the pull ring 161 is pulled. It is convenient to use and does not damage the overall appearance, and no additional opening is required.
[0054] In some embodiments of this application, an annular protrusion 153 is formed on the bottom wall of the housing 11. The annular protrusion 153 is disposed on the outer periphery of the pull ring hole 152 and gradually increases in height towards the center of the pull ring hole 152. The annular protrusion 153 can be used to prevent oil from the outer periphery of the oil guide groove 151 from directly contacting the pull ring 161 along the edge. After the oil in the oil guide groove 151 exceeds the upper edge of the annular protrusion 153, it can be discharged through the edge of the annular protrusion 153. The annular protrusion 153 forms a cavity at the bottom of the bottom wall of the housing 11 that is recessed towards the interior of the suction chamber 111, thereby accommodating the pull ring 161 and providing a receiving space for the pull ring 161.
[0055] In one embodiment of this application, the range hood 1 further includes a reset member 143. One end of the reset member 143 is connected to the first support point, and the other end of the reset member 143 is connected to the connection point 1341 and is adapted to drive the oil scraping device 13 to reset towards the first support member 141. When the oil scraping device 13 is moved by the pull ring 161, in order to ensure that the oil scraping operation can still be performed next time, the reset member 143 is set to drive the oil scraping device 13 back to the initial position, that is, the oil scraping device 13 returns to the front side of the baffle 12, so that the oil scraping device 13 can perform multiple operations.
[0056] In some embodiments, the reset member 143 may be configured as a spring, with the front end of the spring connected to the first support point and the rear end of the spring connected to the oil reservoir 134. The tension of the spring after stretching can provide a forward pulling force to the oil reservoir 134 to keep the oil reservoir 134 close to the baffle 12.
[0057] In some embodiments of this application, the oil reservoir 134 has limiting protrusions 1342 at both ends in the width direction. The limiting protrusions 1342 protrude from the baffle 12 and are disposed on both sides of the baffle 12 in the width direction to restrict the movement direction of the oil reservoir 134 relative to the baffle 12. Limiting protrusions 1342 protruding in the height direction are also formed at both ends in the width direction of the oil reservoir 134. The two limiting protrusions 1342 can be engaged on both sides of the baffle 12 in the width direction, thereby restricting the movement of the oil scraping device 13 relative to the baffle 12, and ensuring the stability of the movement trajectory of the oil reservoir 134.
[0058] In some embodiments of this application, the oil storage shell 134 is constructed in the shape of a strip, with one end of the oil storage shell 134 forming an open oil outlet end. The oil collected inside the oil storage cavity 131 can be led out through the oil outlet end to the bottom wall of the shell 11 and enter the oil guide groove 151 along the inclined direction of the bottom wall of the shell 11.
[0059] In some embodiments of this application, the smoke hood 1 further includes an outer air box 113, the cavity of the outer air box 113 is connected to the air intake cavity 111, an exhaust fan is provided in the cavity of the outer air box 113, and the top plate of the housing 11 has a portion located on both sides of the outer air box 113, the portion of which is aligned with the air intake 112 is blocked by a baffle 12.
[0060] In some embodiments of this application, the range hood 1 further includes a heating element disposed on the surface of the baffle 12 and optionally heating the baffle 12. The heating element can be used to melt solidified oil fumes, thereby reducing the difficulty for the oil scraping device 13 to scrape oil fumes off the baffle 12 and improving scraping efficiency.
[0061] In some embodiments of this application, a baffle 114 is formed on the bottom wall of the housing 11 around the air intake 112. The baffle 114 can prevent oil stains on the bottom wall from flowing out through the air intake 112.
