Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification devices and relates to an easy-to-clean range hood. Background Art

[0002] The range hood is a kitchen appliance that purifies the kitchen environment. The working principle of the range hood is as follows: it is installed on the top of the stove, the power supply of the range hood is turned on, the motor is driven, the wind wheel rotates at high speed, and a negative pressure area is formed in a certain space above the stove, and the indoor fume gas is sucked into the range hood. The fume gas is filtered through the oil net and separated for the first time, and then enters the bellows. The second fume separation is carried out by the rotation of the impeller. The fume in the wind cabinet is subjected to the centrifugal force, and the oil mist condenses into oil droplets, which are collected in the oil cup through the oil path. The purified fume is finally discharged along a fixed path.

[0003] In the prior art, in order to make the range hood have a better suction effect, a smoke baffle is generally provided on the side of the smoke collecting hood of the range hood to block the oil smoke, so that the surrounding oil smoke can be quickly gathered at the smoke inlet, thereby facilitating the range hood to absorb the oil smoke. Figure 1 The range hood shown in the figure adopts such a smoke baffle structure, where the angle between the smoke baffle and the front panel of the smoke hood is usually greater than or equal to 90°. This angle setting enables the range hood to achieve downward movement of negative pressure through the smoke baffle, ultimately improving the range hood's oil fume extraction effect.

[0004] However, since the bottom surface of the smoke baffle of this type of range hood is usually facing downward, it is very inconvenient for users to clean it on a daily basis. They often need to bend over or even squat to successfully clean the bottom surface of the smoke baffle. In addition, due to reasons such as light, it is difficult to determine whether there are any missed areas during cleaning. This is very unfriendly to some users with poor physical conditions and greatly increases the difficulty of cleaning. Secondly, for some smoke baffles that are movable panels, since they do not have a relatively stable force point, it is difficult to control the force. If the force is too small, it is usually not cleaned thoroughly, and if the force is too large, the limiting structure between the smoke baffle and the panel may be damaged.

[0005] Therefore, how to provide a range hood that can quickly and conveniently clean the bottom surface of the smoke shield for collecting oil smoke is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a range hood which can be easily cleaned by turning over the smoke baffle so that the bottom surface of the smoke baffle faces the front side of the range hood.

[0007] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an easy-to-clean range hood, comprising a smoke hood and a smoke baffle arranged on the front side of the smoke hood, the front side of the smoke hood is provided with an air inlet for smoke oil to enter, the smoke baffle is located above the air inlet for collecting the smoke oil to the air inlet, the smoke baffle is connected to the smoke hood in a flippable manner, and the smoke hood is also provided with a driving mechanism that can drive the smoke baffle to flip, and the smoke baffle can be flipped upward under the drive of the driving mechanism so that the bottom surface of the smoke baffle for collecting oil smoke faces the front side of the range hood.

[0008] In order to optimize the overall structure of the driving mechanism so that it can more conveniently drive the smoke baffle to flip upward, preferably, the driving mechanism includes a cylinder, which is built into the smoke hood, and the driving end of the cylinder is connected to the smoke baffle to drive the smoke baffle to flip upward. The side wall of the smoke hood is also penetrated by a through hole for the driving end of the cylinder to pass from the inside to the outside to facilitate the connection of the smoke baffle.

[0009] In order to enable the cylinder to better drive the connection between the smoke hood and the smoke baffle, preferably, the cylinder is hinged on the inner wall located at the rear side or both sides of the smoke hood in an upside-down manner and can rotate synchronously with the smoke hood during the flipping of the smoke baffle, and the driving end of the cylinder is hinged to the smoke baffle and can rotate synchronously with the smoke baffle during the flipping of the smoke baffle.

[0010] In order to enable the cylinder to more stably drive the smoke baffle to flip up and down, preferably, two cylinders are provided, and the two cylinders are spaced apart along the length direction of the smoke baffle. Correspondingly, two through holes are also provided and correspond to the respective cylinders.

[0011] In order to enable the driving mechanism for driving the smoke shield to flip to have different structural driving modes, preferably, the driving mechanism includes a motor, the output end of the motor is connected to a driving gear, the smoke shield is provided with a rotating shaft coinciding with the flipping center of the smoke shield, the rotating shaft is provided with a driven gear that can be adapted to the driving gear, and the motor can drive the smoke shield to flip upward through the meshing transmission of the driving gear and the driven gear.

[0012] In order to enable the motor to be better installed in the smoke hood and enable the motor to drive the smoke shield to flip over a larger range, preferably, the motor is installed inside the smoke hood by setting a bracket to facilitate the engagement of the driving gear and the driven gear, and the smoke shield can also flip downward under the drive of the motor to close the air inlet.

[0013] In order to enable the motor to more smoothly drive the smoke baffle to flip up and down, preferably, two motors and two driving gears are provided, and the two motors and driving gears are spaced apart along the length direction of the rotating shaft. Correspondingly, two driven gears are also provided on the rotating shaft.

[0014] In order to ensure that the relative position of the smoke shield can reach the optimal state when it is in a smoke-collecting state or a cleaning state, preferably, when the smoke shield is not flipped over and is in the first smoke-collecting state, the angle a between the smoke shield and the front side wall of the smoke hood is ≥90°, and when the smoke shield is flipped up to the second cleaning state, the angle b between the smoke shield and the front side wall of the smoke hood is ≤75°.

[0015] Compared with the prior art, the advantages of the present invention are: by arranging a smoke shield that can be flipped upward on the front side of the smoke hood, and by arranging a driving mechanism on the smoke hood that can drive the smoke shield to flip, when the smoke shield needs to be cleaned, the smoke shield can be flipped upward under the drive of the driving mechanism so that the bottom surface of the smoke shield used for collecting oil smoke faces the front side of the range hood, so that the user can quickly and conveniently clean the bottom surface of the smoke shield thoroughly, avoiding the disadvantage of the prior art that requires bending over or even squatting for smooth cleaning, allowing the user to more intuitively observe whether there are any missed areas during cleaning, greatly reducing the difficulty of operating the smoke shield when cleaning, and at the same time enabling the user to better grasp the force required for cleaning, and to a certain extent protecting the connection structure between the smoke shield and the smoke hood.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Figures 1 to 3 What is shown is a schematic diagram of the structure of Example 1. The easy-to-clean range hood in Example 1 mainly includes a smoke collecting hood 1, a smoke baffle 2, a driving mechanism, and the like.

[0025] refer to Figures 1 to 3 As shown, in Example 1, the smoke baffle 2 is arranged on the front side of the smoke hood 1, and the front side of the smoke hood 1 is also provided with an air inlet 1a for smoke oil to enter. The smoke baffle 2 is located above the air inlet 1a to collect the smoke oil to the air inlet 1a. The smoke baffle 2 can be flipped and connected to the smoke hood 1. The smoke hood 1 is also provided with a driving mechanism that can drive the smoke baffle 2 to flip. The smoke baffle 2 can be flipped upward under the drive of the driving mechanism so that the bottom surface of the smoke baffle 2 for collecting oil smoke faces the front side of the range hood.

[0026] In order to optimize the overall structure of the driving mechanism so that the driving mechanism can more conveniently drive the smoke baffle 2 to flip upward, refer to Figure 2 and Figure 3 As shown, the driving mechanism in Example 1 mainly includes a cylinder 3, which is built into the smoke hood 1. The driving end 3a of the cylinder 3 is connected to the smoke baffle 2 and can drive the smoke baffle 2 to flip upward. The side wall of the smoke hood 1 is also penetrated by a through hole 1b for the driving end 3a of the cylinder 3 to pass from the inside to the outside to facilitate the connection with the smoke baffle 2.

[0027] Secondly, in order to optimize the driving structure and installation method of the cylinder 3 so that the cylinder 3 can be better driven to connect between the smoke hood 1 and the smoke baffle 2, refer to Figure 2 and Figure 3 As shown, in Example 1, the cylinder 3 is hinged on the inner wall at the rear side or both sides of the smoke hood 1 in an upside-down manner and can rotate synchronously with respect to the smoke hood 1 during the flipping of the smoke baffle 2. The driving end 3a of the cylinder 3 is hinged to the smoke baffle 2 and can rotate synchronously with respect to the smoke baffle 2 during the flipping of the smoke baffle 2.

[0028] At the same time, in order to enable the cylinder 3 to more smoothly drive the smoke baffle 2 to flip up and down relative to the smoke hood 1, two cylinders 3 are further provided in Example 1, and the two cylinders 3 are spaced apart along the length direction of the smoke baffle 2 so as to more smoothly drive the smoke baffle 2 to rotate. Correspondingly, two through holes 1b are also provided here and correspond to the respective cylinders 3, so as to facilitate the two cylinders 3 to pass through the through holes 1b respectively.

[0029] Example 2

[0030] In order to enable the driving mechanism for driving the smoke baffle 2 to flip to have different driving modes, embodiment 2 also provides another implementation mode of the driving mechanism. Figures 4 to 7 The structure diagram of Example 2 is shown.

[0031] refer to Figure 4 and Figure 7 As shown, in Example 2, the driving mechanism mainly includes a motor 4, and a driving gear 4a that can rotate synchronously with the output end is connected to the output end of the motor 4. At the same time, a rotating shaft 2a that can coincide with the flipping center of the smoke baffle 2 is specially arranged on the smoke baffle 2. A driven gear 2b that can adapt to the driving gear 4a is also provided on the rotating shaft 2a. Through the meshing transmission of the driving gear 4a and the driven gear 2b, the motor 4 can drive the smoke baffle 2 to flip upward and put the smoke baffle 2 in a cleaning state. Since there is no need to set a cylinder in Example 2, there is no need to set a through hole 1b on the smoke hood 1 to affect the overall appearance of the range hood.

[0032] refer to Figure 7 As shown, in Example 2, in order to enable the motor 4 to be better installed inside the smoke hood 1 and enable the motor 4 to drive the smoke baffle 2 to flip over a larger range, the motor 4 here is installed inside the smoke hood 1 by providing a bracket 4b to facilitate the engagement of the driving gear 4a and the driven gear 2b, and the smoke baffle 2 can also flip downward under the drive of the motor 4 to close the air inlet 1a.

[0033] In Example 2, in order to enable the motor 4 to drive the smoke baffle 2 to flip up and down more smoothly, two motors 4 and two driving gears 4a are provided, and the two motors 4 and the driving gears 4a are spaced apart along the length direction of the rotating shaft 2a. Correspondingly, two driven gears 2b on the rotating shaft 2a are also provided and each is adapted to the corresponding driving gear 4a.

[0034] Another point is that in the first or second embodiment, in order to make the relative position of the smoke baffle 2 in the smoke-collecting state or in the cleaning state reach the optimal state, Figure 4 The figure shows the first state of the smoke baffle 2 when it is not turned over and is in the state of collecting smoke. At this time, the angle a between the smoke baffle 2 and the front side wall of the smoke collecting hood 1 is ≥90°. Figure 5The figure shows the second state of the smoke baffle 2 when it is turned up for cleaning. At this time, the angle b between the smoke baffle 2 and the front side wall of the smoke hood 1 is ≤75°, and the preferred range of the angle b is 0-30°. By turning the bottom surface of the smoke baffle 2 to a position roughly facing the user or facing the user, most users can operate without bending over when doing cleaning work; at the same time, because the bottom surface of the smoke baffle 2 faces the user, the user's vision will not be disturbed, and it can be ensured that every area of ​​the bottom surface of the smoke baffle 2 can be cleaned. When the angle b is close to 0°, the smoke baffle 2 is attached to the side wall of the smoke hood 1.

[0035] In addition, additional explanation is required: in Example 1 or Example 2, a smoke baffle 2 that can be flipped upward is set on the front side of the smoke hood 1, and a driving mechanism that can drive the smoke baffle 2 to flip is set on the smoke hood 1. When the user needs to clean the smoke baffle 2, the smoke baffle 2 can be flipped upward under the drive of the driving mechanism so that the bottom surface of the smoke baffle 2 for collecting oil smoke faces the front side of the range hood, so that the user can quickly and conveniently clean the bottom surface of the smoke baffle 2 thoroughly, avoiding the disadvantage of the prior art that bending over or even squatting is required for smooth cleaning, so that the user can more intuitively observe whether there are any missed areas during cleaning, which greatly reduces the difficulty of operation when cleaning the smoke baffle 2. At the same time, it also enables the user to better grasp the force required for cleaning, and to a certain extent protects the connection structure between the smoke baffle 2 and the smoke hood 1.
