[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] The range hood generates high-temperature steam through the heating element. When the high-temperature steam passes through the flue and the oil net, it can penetrate into every corner and surface of the range hood's cleaning channel inner wall and oil net, including tiny gaps and hard-to-reach areas, softening and dissolving the oil stains, which can be discharged with the condensed water to achieve the effect of cleaning the oil net and the inner wall. Therefore, in the related art, a water box and an oil box are provided on the range hood. The water box generally provides a water source for high-temperature cleaning, and the oil box can collect the oil stains after cleaning. In order to make the appearance of the range hood more integrated, the oil box and the water box are similar in appearance. When the oil box and the water box are installed at the same time, there is a possibility of misinstallation.

[0051] The utility model provides a range hood, aiming to solve the problem of the possibility of mis-installation when the oil box and the water box are installed at the same time in the existing range hood.

[0052] See also Figures 1 to 5 In one embodiment of the utility model, the range hood 100 includes a shell 1, a water box assembly 3 and an oil box assembly 4, and a first mounting structure 21 and a second mounting structure 22 are provided at the bottom of the shell 1; the water box assembly 3 and the oil box assembly 4 are correspondingly mounted on the first mounting structure 21 and the second mounting structure 22; wherein, at least one of the first mounting structure 21 and the second mounting structure 22 is formed with an anti-fool structure.

[0053] It should be noted that the shell 1 may refer to the overall structure of the outer shell of the range hood 100 body, or may refer to a partial structure on the range hood 100 body for installing the water box assembly 3 and the oil box assembly 4. The shell 1 may be an integrally formed component or an assembled component. The specific design may be based on actual conditions, and the embodiments of this specification do not limit this.

[0054] The first mounting structure 21 and the second mounting structure 22 may be two mounting components that are separately provided, or may be two mounting structures formed on one mounting component. The specific design may be based on actual conditions, and the embodiments of this specification do not limit this.

[0055] It should also be noted that, since the water in the water box assembly 3 is a consumable, when the water is exhausted, it is necessary to add water to the water box assembly 3. In this case, the water box assembly 3 needs to be disassembled and filled with water, and then assembled with the first mounting structure 21 on the shell 1, and the water suction port on the water box assembly 3 is connected to the water inlet port of the water inlet assembly 7 arranged in the shell 1, so that the water inlet assembly 7 can suck the water in the water box assembly 3.

[0056] As for the oil box assembly 4, the oil box assembly 4 is used to receive and collect the oil dirt generated after cleaning. After the oil box assembly 4 is full, it also needs to be cleaned and then assembled to the second mounting structure 22 on the housing 1. In this way, after the water box assembly 3 is filled with water and the oil box assembly 4 is cleaned, or when the water box assembly 3 and the oil box assembly 4 are installed for the first time, there is a need to assemble the two boxes at the same time.

[0057] It should also be noted that "foolproofing" is a structure designed to avoid malfunctions or accidents caused by human errors or accidents. Foolproofing can be implemented in various ways, including but not limited to the following forms: physical restrictions or mechanical foolproofing, etc. The so-called physical foolproofing refers to setting physical barriers or restrictions in the system through design and construction to prevent incorrect assembly, operation or use. Such restrictions can be physical, visible structural elements, or designs of specific shapes or positions. Mechanical foolproofing refers to methods of preventing incorrect operations or improper use by designing and implementing mechanical devices or mechanisms to ensure that only correct operations can be performed under specific conditions.

[0058] Specifically, in the technical solution of the present application, the foolproof structure mainly prevents the user from erroneous assembly by means of physical restrictions. For example, the first mounting structure 21 is provided with a slot, and a holding arm that cooperates with the slot is provided on the water box assembly 3, while the second mounting structure 22 is provided as a screw-on component, and a threaded hole that is screwed to the screw-on component is provided on the oil box assembly 4. The two form a foolproof structure through completely different assembly forms. Of course, the above-mentioned card connection and screw connection to form a foolproof structure are only used for description purposes and do not constitute a limitation on the technical features of this solution.

[0059] In the technical solution of the utility model, a first mounting structure 21 and a second mounting structure 22 are provided at the bottom of the shell 1, and the water box assembly 3 and the oil box assembly 4 are correspondingly mounted on the first mounting structure 21 and the second mounting structure 22. A fool-proof structure is formed by at least one of the first mounting structure 21 and the second mounting structure 22, which can prevent the water box assembly 3 or the oil box assembly 4 from being installed incorrectly when the water box assembly 3 or the oil box assembly 4 is installed to the bottom of the shell 1, resulting in the water box assembly 3 and the oil box assembly 4 not being able to work properly, so as to solve the problem of the possibility of mis-installation when the oil box and the water box are installed at the same time in the existing range hood 100.

[0060] Specifically, see Figure 1 and Figure 2In this embodiment, the water box assembly 3 and the oil box assembly 4 are spaced apart in the transverse direction, and correspondingly, the first mounting structure 21 and the second mounting structure 22 are distributed in the transverse direction. In this way, the water box assembly 3 is arranged side by side in the transverse direction, and the water box assembly 3 and the oil box assembly 4 can each be set to half the length of the bottom of the shell 1, so that the water box assembly 3 and the oil box assembly 4 can have the same appearance, so that the appearance of the range hood 100 can maintain overall consistency and beauty.

[0061] Specifically, see Figures 6 to 10 In this embodiment, the water box assembly 3 is provided with a first hanging portion 31, and the oil box assembly 4 is provided with a second hanging portion 41; the first mounting structure 21 includes at least one first mounting portion, and the first mounting portion is provided with a first card groove 2a that is engaged with the first hanging portion 31, and the second mounting structure 22 includes at least one second mounting portion, and the second mounting portion is provided with a second card groove 2b that is engaged with the second hanging portion 41; the first card groove 2a and the second card groove 2b are arranged differently, so that the first mounting structure 21 and the second mounting structure 22 are arranged differently to form the fool-proof structure.

[0062] It can be understood that the hanging part is a specific component or structure used to hang or install parts, which can generally be a structural form such as a hanging ear. In order to adapt and assemble with the hanging ear, the first mounting part is provided with the first slot 2a adapted to the first hanging part 31, and the second mounting part is provided with the second slot 2b adapted to the second hanging part 41. The first slot 2a and the second slot 2b are differently arranged, and correspondingly, the first hanging part 31 and the second hanging part 41 are differently arranged. Then, when the water box assembly 3 and the oil box assembly 4 are reversely assembled, there is a situation that the first hanging part 31 does not match the second slot 2b; and / or the second hanging part 41 does not match the first slot 2a, thereby forming the anti-fool structure.

[0063] It can be understood that in the present embodiment, "the first card slot 2a and the second card slot 2b are differently arranged". Specifically, the first card slot 2a and the second card slot 2b can be differently arranged in shape. For example, the shape of the first card slot 2a is set to be semicircular, and the other is set to be rectangular. It can also be that the position of the first card slot 2a in the longitudinal direction is different from the position of the second card slot 2b in the longitudinal direction, and so on. Of course, the specific form of "the first card slot 2a and the second card slot 2b are differently arranged" is not limited to the above examples. Technical personnel in the relevant field may make other changes under the inspiration of the technical essence of the embodiments of this specification. However, as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.

[0064] In this embodiment, the groove depths or groove widths of the first card slot 2a and the second card slot 2b are set differently, and correspondingly, the lengths or thicknesses of the first hanging portion 31 and the second hanging portion 41 are set differently.

[0065] In this way, when the length of the first hanging portion 31 is set to be greater than the length of the second hanging portion 41, when the water box assembly 3 is assembled to the second mounting portion, at least part of the first hanging portion 31 is exposed outside the second card slot 2b, so that the user can promptly discover the reverse installation.

[0066] Of course, in addition to the above-mentioned different depths or widths of the first card slot 2a and the second card slot 2b, in other embodiments, the thickness direction of the first card slot 2a and the second card slot 2b can also be set differently, and correspondingly, the widths of the first hanging portion 31 and the second hanging portion 41 are also set differently. In this way, by setting the depths and / or widths of the two card slots differently, the foolproof structure can be simply formed, which is simple in production and manufacturing process, and the assembly form is also simple.

[0067] Specifically, in this embodiment, the notches of the first card slot 2a and the second card slot 2b are arranged opposite to each other in the transverse direction; or, the notches of the first card slot 2a and the second card slot 2b are arranged away from each other in the transverse direction.

[0068] It should be noted that the water box assembly 3 includes a water box and a first cover body 34 covering the opening of the water box 33. Since the first hanging portion 31 can be extended outwardly toward the upper side of the water box 33, the second hanging portion 41 can be extended outwardly toward the upper side of the oil box. Of course, the first hanging portion 31 can also be extended toward the middle of the upper side of the water box 33, and the second hanging portion 41 can also be extended toward the middle of the upper side of the oil box.

[0069] In this way, when the folded extension directions of the first hanging portion 31 and the second hanging portion 41 are different, the orientations of the notches of the first clamping slot 2a and the second clamping slot 2b are also different.

[0070] It should be noted that when the water box assembly 3 is installed on the range hood 100, the water suction port on the water box assembly 3 needs to be docked with the water inlet port of the water inlet assembly 7 on the range hood 100. Therefore, the water box assembly 3 needs to be set to a horizontal state to effectively ensure the water absorption of the range hood 100. Because the hanging part is provided at one end of the water box assembly 3, when assembling the water box assembly 3, the first hanging part 31 is easily deformed, causing the box body to tilt, which is not conducive to the smoke removal work of the range hood 100.

[0071] Similarly, when the oil box assembly 4 is tilted, there may be an assembly gap between the end where the second hanging portion 41 is not provided and the bottom of the housing 1, which affects the appearance.

[0072] Furthermore, in the present embodiment, two of the first mounting parts and two of the second mounting parts are provided, and one of the first hanging parts 31 is provided at both ends of the water box assembly 3 in the lateral direction, and the two first hanging parts 31 are respectively clamped with the two first card grooves 2a; and one of the second hanging parts 41 is provided at both ends of the oil box assembly 4 in the lateral direction, and the two second hanging parts 41 are respectively clamped with the two second card grooves 2b.

[0073] With such a configuration, the water box assembly 3 can be hung on the bottom of the range hood 100 through the two first hanging parts 31, which can provide better support and balance, so that the water box assembly 3 is more firmly hung on the bottom of the range hood 100, and can reduce shaking or tilting caused by imbalance or instability, ensuring that the water box assembly 3 is not easily displaced or dropped during use, and the weight of the water box assembly 3 is evenly distributed on the two first hanging parts 31, which can reduce the burden of a single hanging part, extend the service life of the first hanging part 31, and reduce the risk of damage caused by the first hanging part 31 bearing too much weight. It also reduces the possibility of assembly gaps, and the overall appearance is better.

[0074] Similarly, the oil box assembly 4 is hung on the bottom of the range hood 100 through the two second hanging parts 41, which can provide better support and balance, thereby extending the service life of the second hanging part 41 and reducing the risk of damage caused by the second hanging part 41 bearing too much weight. It also reduces the possibility of assembly gaps.

[0075] It should be noted that when the first hanging portion 31 extends outward toward the upper side of the water box 33 and the second hanging portion 41 extends outward toward the upper side of the oil box, the first cover 34 and the second cover can be directly buckled downward at the opening of the water box 33 and the opening of the oil box, respectively, and the assembly is simple. However, the first hanging portion 31 extends toward the outside of the water box 33 and the second hanging portion 41 extends toward the outside of the oil box. When assembled at the bottom of the housing 1, the first hanging portion 31 and the second hanging portion 41 both occupy space outward, which affects the overall appearance of the range hood 100.

[0076] Furthermore, in this embodiment, the notches of the two first card slots 2a are arranged to be away from each other; and the notches of the two second card slots 2b are arranged to be away from each other.

[0077] In this way, the first hanging portion 31 and the second hanging portion 41 both extend toward the middle of the upper side of the box body, and respectively correspond to the two first card slots 2a and the two second card slots 2b that are arranged opposite to each other with respect to the notch. When the first hanging portion 31 and the second hanging portion 41 extend toward the middle of the upper side of the box body, the first hanging portion 31 and the second hanging portion 41 do not occupy the outward space, and the integrity is better.

[0078] Furthermore, in order to cover the opening of the water box 33 with the first cover body 34, the first cover body 34 can be moved from the lower side of the two first hanging parts 31 to the top of the opening of the water box 33 by side pushing, and then the first cover body 34 is pressed downward to complete the assembly of the water box assembly 3.

[0079] Specifically, see Figure 6 In a specific embodiment, the range hood 100 further includes at least one fixing seat 2 disposed at the bottom of the housing 1, the fixing seat 2 being provided with the first card slot 2a and the second card slot 2b, the fixing seat 2 being provided with a part of the first card slot 2a to form a first mounting portion, and the fixing seat 2 being provided with a part of the second card slot 2b to form a second mounting portion. Thus, by providing one fixing seat 2, the first card slot 2a and the second card slot 2b required for the water box assembly 3 and the oil box assembly 4 to be installed can be provided, the structure is simple, and the number of fixing seats 2 required for installation is also small, thereby reducing the number of steps in the installation process.

[0080] See also Figure 7 and Figure 8In a specific embodiment, the fixing seat 2 includes a first seat body 201, and a first limiting arm 202 and a second limiting arm 203 disposed on one side of the first seat body 201. The first limiting arm 202 and the first seat body 201 define the first clamping groove 2a with a notch facing the peripheral side of the first seat body 201, and the second limiting arm and the first seat body 201 define the second clamping groove 2b with a notch facing the peripheral side of the first seat body 201. In this way, by disposing the limiting arm on one side of the first seat body 201, the structure of forming the first clamping groove 2a and the second clamping groove 2b between the first seat body 201 and the first seat body 201 is simple.

[0081] It can be understood that the first limiting arm 202 and the second limiting arm 203 can be provided in plurality, and the plurality of the first limiting arms 202 are arranged at intervals along the longitudinal direction, and the plurality of the second limiting arms 203 are arranged at intervals along the longitudinal direction. The first card slot 2a is defined between the plurality of the first limiting arms 202 and the first seat body 201, and the second card slot 2b is defined between the plurality of the second limiting arms 203 and the first seat body 201. In this way, each of the first limiting arms 202 and each of the second limiting arms 203 can share part of the weight, and the bearing capacity is also strong. At the same time, the plurality of the first limiting arms 202 and the plurality of the second limiting arms 203 are hollowed out at intervals, which can also save materials when manufacturing the fixed seat 2.

[0082] See also Fig. 9 and Fig.10 In another specific embodiment, the fixing seat 2 includes a second seat body 204, and a third limiting arm 205 and a fourth limiting arm 206 extending outward from the second seat body 204, the first clamping groove 2a with a notch facing the peripheral side of the second seat body 204 is defined between the third limiting arm 205 and the bottom of the shell 1, and the second clamping groove 2b with a notch facing the peripheral side of the second seat body 204 is defined between the fourth limiting arm 206 and the bottom of the shell 1. Thus, compared with the above embodiment, the fixing seat 2 in this embodiment has a simpler structure, a lower manufacturing cost, and can also play a clamping role.

[0083] Similarly, the third limiting arm 205 and the fourth limiting arm 206 can also be provided in plurality, and the first card slot 2a is defined between the plurality of the third limiting arms 205 and the bottom of the shell 1, and the second card slot 2b is defined between the plurality of the fourth limiting arms 206 and the bottom of the shell 1.

[0084] See also Fig. 9 and Fig.10In this embodiment, the fixing seat 2 is provided with a through hole b, and the through hole b is used to connect the water inlet of the water inlet assembly 7 and the water suction port of the water box assembly 3. In this way, the through hole b is provided on the fixing seat 2, and the fixing seat 2 is not only used as a fixed mounting member, but also as a component for connecting the water box assembly 3 and the water inlet assembly 7, and the degree of integration is high.

[0085] It can be understood that in order to ensure that the hanging parts of the water box assembly 3 and the oil box assembly 4 can be stably fitted when they are clamped in the corresponding slots, it can be understood that the inner wall surface of the first slot 2a and the side wall surface of the first hanging part 31 are set to an interference fit, and the inner wall surface of the second slot 2b and the side wall surface of the second hanging part 41 are set to an interference fit. When the user assembles, a certain damping feeling can be felt. However, if the water box assembly 3 is pushed along the width direction of the first slot 2a, and the oil box assembly 4 is pushed along the width direction of the second slot 2b, the damping feeling caused by the interference fit is felt throughout the entire process, which will also make the user feel the difficulty of assembly.

[0086] Furthermore, in order to ensure the user experience, in this embodiment, a first concave-convex structure (not shown) is provided on the side wall of the first card slot 2a; and / or a second concave-convex structure (not shown) is provided on the side wall of the second card slot 2b.

[0087] With such a configuration, the inner wall of the first card slot 2a and the first hanging portion 31 can be clearance-fitted, and when the water box assembly 3 is pushed to slide along the width direction of the first card slot 2a, when there is no contact with the first concave-convex structure, the water box assembly 3 can be easily assembled by the user, and when the water box assembly 3 is almost installed in place, or when the assembly stroke is more than halfway, the first hanging portion 31 cooperates with the first concave-convex structure to form an interference fit. Similarly, when the second hanging portion 41 of the oil box assembly 4 is almost installed in place, or when the assembly stroke is more than halfway, the second hanging portion 41 cooperates with the second concave-convex structure to form an interference fit.

[0088] It can be understood that the first concave-convex structure can be a plurality of convex points arranged on two opposite side walls of the first card slot 2a, or a plurality of convex points arranged on one of the two opposite side walls of the first card slot 2a. Similarly, the second concave-convex structure can be a plurality of convex points arranged on two opposite side walls of the second card slot 2b, or a plurality of convex points arranged on one of the two opposite side walls of the second card slot 2b.

[0089] Of course, in other embodiments, the first hanging portion 31 and the second hanging portion 41 may be provided with concave-convex structures respectively, while no concave-convex structures are provided on the side walls of the first groove and the second card groove 2b, and the above-mentioned damping assembly feel can also be achieved.

[0090] Furthermore, in the present embodiment, the water box assembly 3 is provided with a water suction port connected to the inner cavity of the water box, the shell 1 is provided with a water inlet assembly 7, and the water inlet assembly 7 is provided with a water inlet; the water box assembly 3 is slidably mounted on the first mounting structure 21 along the longitudinal direction, and in the longitudinal movement of the water box assembly 3, there is a working position in which the water suction port and the water inlet are aligned, and in the working position, the water inlet assembly 7 absorbs water into the inner cavity of the water box through the water suction port. Therefore, ensuring the alignment between the water suction port and the water inlet is a prerequisite for ensuring that the range hood 100 can be cleaned normally at high temperature.

[0091] See also Fig.11 In this embodiment, a limiting portion 32 is further provided on the water box assembly 3, and the first mounting structure 21 further includes a matching portion 23 that matches the limiting portion, and the limiting portion 32 is used to match the matching portion 23 to limit the water box assembly 3 to the working position. In this way, when the water box assembly 3 is assembled to the first mounting structure 21 along the longitudinal sliding, when the water suction port and the water inlet are aligned, the limiting portion 32 and the matching portion 23 are abutted to prevent further sliding of the water box assembly 3, so that the water suction port and the water inlet are misaligned.

[0092] For further information, see Figure 2 and Fig.12 In this embodiment, the housing 1 includes a smoke hood 5, and the smoke hood 5 has a rear side wall 51 and two side walls 52 that are oppositely arranged in the transverse direction. In addition, the smoke hood 5 may also have a front side wall that is oppositely arranged to the rear side wall 51 in the front-to-back direction, and the front side wall, the rear side wall 51 and the two side walls 52 jointly define an inner cavity of the smoke hood 5.

[0093] It should be noted that the smoke hood 5 is a vital component of the range hood 100. Its main function is to capture and gather the smoke generated during the cooking process so that it can be discharged to the outside through the fan system to keep the kitchen air fresh. Therefore, an air inlet is provided on the smoke hood 5 to allow smoke to enter the smoke hood 5.

[0094] In one embodiment, in order to improve the flow efficiency of the intake air duct, the rear side wall 51 is provided with a guide member 6 extending in the vertical direction. By providing the guide member 6 extending in the vertical direction, left and right double flow channels are formed at the front end of the air intake, making the oil fume suction and exhaust smoother.

[0095] Specifically, the guide member 6 can be completely fixed. Specifically, the guide member 6 includes an upper rectifying portion 61 and a lower rectifying portion 62 which are sequentially arranged along the up-down direction. The upper rectifying portion 61 and the lower rectifying portion 62 are fixedly mounted on the rear side wall 51 of the smoke hood 5, wherein the upper rectifying portion 61 contacts the cavity wall of the inner cavity on opposite sides in the front-to-back direction of the smoke hood 5, respectively, and the upper rectifying portion 61 is formed with rectifying side surfaces on opposite sides in the left-to-right direction of the smoke hood 5, the rectifying side surfaces extend in the direction from the air inlet to the smoke exhaust port, and are spaced apart from the cavity wall of the inner cavity in the left-to-right direction, and the distance between the two rectifying side surfaces decreases from the rear to the front. After the oil smoke enters the inner cavity through the air inlet, it can be rectified by the upper rectifying part 61 of the guide member 6, so that the oil smoke enters the exhaust port in an approximately parallel manner, thereby preventing the oil smoke from colliding at the exhaust port, thereby reducing the probability of generating collision noise, and thus reducing the noise of the range hood 100; and because the upper rectifying part 61 can rectify the oil smoke into an approximately parallel manner to enter the exhaust port, the probability of oil smoke on both sides generating vortices can be reduced, thereby reducing the probability of generating aerodynamic noise, and thus reducing the noise of the range hood 100. Furthermore, because the flow rate of oil smoke near the rear position is larger and more concentrated than the flow rate near the front position, the distance between the two rectifying sides is set to decrease from the rear to the front, thereby better rectifying the oil smoke with a larger flow rate near the rear, and improving the rectifying effect, thereby reducing the noise of the range hood 100.

[0096] Of course, the upper rectifying part 61 of the guide member 6 can also be movably arranged. Specifically, the lower rectifying part 62 is fixedly installed on the rear side wall 51 of the smoke collecting hood 5, and the upper rectifying part 61 is arranged to swing laterally, so that under the swing of the upper rectifying part 61, the cross-sectional area size in the left and right air inlet paths of the range hood 100 changes, and the air intake ratio on the left and right sides is changed. Therefore, accurate smoking can be performed for cooking on the left or right side of the stove, improving the single-sided smoking effect, adapting to the use scenarios of single stove / single-side use of stove or steaming and stir-frying, so that the smoking effect is optimally matched and the noise is low.
