[0043] 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.

[0044] 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.

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.

[0046] 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 quickly heat the oil smoke and the grease particles in the oil smoke. When the high-temperature steam contacts the oil smoke, it can penetrate into the inner wall of the cleaning channel and the oil net of the range hood and other corners and surfaces, including small gaps and hard-to-reach areas, to soften and dissolve the oil stains, which can be discharged with condensed water to achieve the effect of cleaning the oil net and the inner wall. The water in the water cup provides a water source for the range hood to generate high-temperature steam. At present, most of the water cups on the market are external water cups. In the related technology, the water cup is detachably mounted on the range hood through a fixed seat, and the water cup is provided with a hanging ear that cooperates with the fixed seat. However, the existence of the hanging ear makes the operation steps of assembling the water cup cumbersome and difficult to assemble.

[0047] The utility model provides a water box assembly, aiming to solve the problem that the operation steps are complicated and difficult to assemble when assembling a water cup. Figure 1 A schematic structural diagram of an embodiment of a water box assembly provided by the utility model; Figure 2 for Figure 1 Exploded diagram of the grey water box assembly; Figure 3 for Figure 1 A schematic diagram of an embodiment of a middle cover body; Figure 4 for Figure 1 A schematic diagram of another embodiment of the middle cover; Figure 5 for Figure 1 Schematic diagram of the middle installation part; Figure 6 for Figure 1 Schematic diagram of the middle box; Figure 7 This is a structural schematic diagram of an embodiment of a range hood provided by the utility model.

[0048] See also Figure 1 and Figure 2In one embodiment of the utility model, the water box assembly 100 is used for a range hood 200, and the water box assembly 100 includes a box body 1 and a cover body 3, the box body 1 has two ends in the horizontal direction, and an upper opening a is provided, and a hanging portion 11 extending toward the middle of the upper side of the box body 1 is provided at least at one end of the upper side of the box body 1, and a mounting portion 2 is provided on the inner side of the hanging portion 11 on the upper side of the box body 1, and the mounting portion 2 protrudes from the hanging portion 11 toward the middle of the box body 1; the cover body 3 is arranged to cover the opening a and is staggered with the hanging portion 11, and the end of the cover body 3 adjacent to the hanging portion 11 is supported on the mounting portion 2.

[0049] It should be noted that in the related art, a hanging ear is provided on the top of the box body. In order to ensure the beautiful appearance of the assembly, the hanging ear is bent inward. Therefore, when the cover of the box body needs to be assembled, if it is pressed downward directly, there will be interference between the hanging ear and the cover body. Therefore, when assembly is required, the cover body needs to be moved from the lower side of the hanging ear to the opening of the box body by side pushing, and then the cover body is pressed downward to complete the assembly. When a straw for supplying water to the range hood is provided at the bottom of the cover body, the side pushing method is also affected by the straw, and the straw interferes with the side wall of the box body, which further increases the difficulty of assembly.

[0050] It can be understood that the mounting portion 2 can be integrally formed with the box body 1 and is a part of the box body 1, that is, the mounting portion 2 is formed on the inner wall of the box body 1. Of course, the mounting portion 2 can also be an independently arranged component installed in the box body 1. The specific amount can be determined based on actual conditions, and the embodiments of this specification do not limit this.

[0051] It can be understood that the upper side of the box body 1 is provided with an opening a, and the size of the cover body 3 can be set to match the size of the opening a. Since the mounting portion 2 is arranged in the box body 1, and the cover body 3 is supported on the mounting portion 2, the mounting opening defined between the mounting portion 2 and the opening a of the box body 1 is smaller than the opening a of the box body 1, and the cover body 3 can be set to a size that matches the size of the mounting opening.

[0052] In the technical solution of the utility model, the box body 1 has two ends in the horizontal direction, and an opening a is set on the upper side. The water box assembly 100 is also provided with a cover body 3 covering the opening a. The upper side of the box body 1 is provided with a hanging portion 11 extending toward the middle of the upper side of the box body 1 at at least one end. The hanging portion 11 is used to be assembled with a fixing seat of the range hood 200. The upper side of the box body 1 is provided with a mounting portion 2 on the inner side of the hanging portion 11. The mounting portion 2 protrudes toward the middle of the box body 1. The hanging portion 11 is provided The cover body 3 and the hanging part 11 are staggered in the up and down directions, and the end of the cover body 3 adjacent to the hanging part 11 is supported on the mounting part 2. When assembling the cover body 3, it is only necessary to press the cover body 3 directly downward so that the cover body 3 is supported on the mounting part 2. The cover body 3 and the box body 1 are enclosed to form a water containing cavity. By directly pressing the cover body 3 downward, the cover body 3 and the box body 1 can be assembled. The operation is simple, so as to solve the problem of complicated operation steps and difficult assembly when assembling the water cup.

[0053] It is understandable that when the water box assembly 100 is installed on the range hood 200, the water suction port on the water box needs to be docked with the water inlet on the range hood 200. Therefore, the water box assembly 100 needs to be set to a horizontal state to effectively ensure the water absorption of the range hood 200. Because the hanging portion 11 is provided at one end of the box body 1, when the water box assembly 100 is assembled, the hanging portion 11 is easily deformed, causing the box body 1 to tilt, which is not conducive to the smoke removal work of the range hood 200.

[0054] Therefore, in another embodiment, a hanging portion 11 is provided at both ends of the box body 1; two mounting portions 2 are provided, each mounting portion 2 is arranged on the inner side of the corresponding hanging portion 11, and both ends of the cover body 3 are supported by the two mounting portions 2.

[0055] With such a configuration, the water box assembly 100 can be hung on the bottom of the range hood 200 through the two hanging parts 11, which can provide better support and balance, so that the water box assembly 100 can be more firmly suspended on the bottom of the range hood 200, and can reduce shaking or tilting caused by imbalance or instability, ensuring that the water box assembly 100 is not easy to shift or fall off during use, and the weight of the water box assembly 100 is evenly distributed on the two hanging parts 11, which can reduce the burden of a single hanging part 11, extend the service life of the hanging part 11, and reduce the risk of damage caused by the hanging part 11 bearing too much weight.

[0056] Furthermore, since the two hanging portions 11 both extend toward the middle of the upper side of the box body 1, in order to prevent the other end of the cover body 3 from interfering with the other hanging portion 11 when the cover body 3 is directly pressed downward for assembly, correspondingly, another mounting portion 2 is provided on the upper side of the box body 1 on the inner side of the other hanging portion 11, so that the two mounting portions 2 both protrude toward the middle direction of the box body 1 and the two hanging portions 11 are provided, which facilitates the assembly of the cover body 3.

[0057] It should be noted that, since the cover body 3 is provided with a water suction port for docking with the water inlet of the range hood 200, and is generally arranged at one end of the cover body 3 in the horizontal direction, but not in the middle of the cover body 3, the installation direction of the cover body 3 determines whether the water suction port can be aligned with the water inlet.

[0058] Further, in order to enable the user to be reminded when the cover body 3 is assembled with the mounting portion 2 to reduce the possibility of misassembly, please refer to Figure 4 and Figure 5 In this embodiment, a positioning structure is provided between the cover body 3 and the mounting portion 2, and the positioning structure includes a positioning portion 41 provided on one of the mounting portion 2 and the cover body 3, and a matching portion 42 provided on the other and matched with the positioning portion 41. By providing a positioning structure that matches one end of the cover body 3 on one of the mounting portions 2, when the cover body 3 is installed in the reverse direction, the positioning portion 41 and the matching portion 42 cannot match each other, which will cause one end of the cover body 3 to be tilted and uneven, which can indicate that the cover body 3 is installed incorrectly, and avoid finding that the water suction port and the water inlet on the cover body 3 cannot be connected after the water box assembly 100 is installed in place.

[0059] See also Figure 4 and Figure 5 In this embodiment, one of the mounting portion 2 and the cover body 3 is provided with a clamping portion 51, and the other is provided with a buckle portion 52 that is engaged with the clamping portion 51. In this way, the design of the clamping portion 51 and the buckle portion 52 can ensure that the mounting portion 2 and the cover body 3 are firmly fixed to prevent loosening or falling off during use, thereby improving the stability of the overall structure; and through the design of the clamping portion 51 and the buckle portion 52, the installation and removal process becomes simpler and more convenient, without the need for additional tools or complicated operations.

[0060] Specifically, see Figure 4 In this embodiment, the cover body 3 includes a cover plate 31 and a protrusion 32 protruding from the bottom of the cover plate 31, and the cover plate 31 is supported on the mounting portion 2; the mounting portion 2 and the protrusion 32 are oppositely arranged side portions, one of which is provided with the clamping portion 51, and the other is provided with the buckling portion 52.

[0061] In this way, the holding portion 51 and the buckling portion 52 are arranged on the side instead of on the side where the cover plate 31 and the mounting portion 2 are opposite to each other, so that a good flatness can be maintained between the cover plate 31 and the mounting portion 2, making the appearance more integrated and also conducive to sealing.

[0062] In this embodiment, one of the clamping portion 51 and the buckling portion 52 includes a hook, and the other includes a slot. Of course, the clamping portion 51 and the buckling portion 52 are not limited to the above-mentioned hook and slot cooperation, but can also be a buckle and a slot, or a hook and a hook cooperation. The clamping portion 51 and the buckling portion 52 are not limited to the above examples. Under the inspiration of the technical essence of the embodiments of this specification, technicians in the relevant field may also make other changes, but as long as the functions and effects achieved are the same or similar to the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.

[0063] Because the water box is extended in the horizontal direction, the clamping structure between the cover body 3 and the mounting portion 2 can only fix the two ends of the cover body 3 in the horizontal direction, and the fixation of the two sides of the cover body 3 in the vertical direction is unstable. Therefore, please refer to Figure 4 , Figure 5 and Figure 7 In this embodiment, a limiting groove b is provided on the side wall of the box body 1, and a clamping protrusion 33 cooperating with the limiting groove b is provided on the peripheral side of the cover body 3. It should be noted that the limiting groove b can be the limiting groove b formed by the limiting rib 12 protruding on the side wall of the box body 1 and the side wall of the box body 1, and the limiting rib 12 is used to limit the position when the cover body 3 moves upward. In this way, the peripheral side of the cover body 3 can have a more stable fixed structure with the box body 1 through the form of the clamping protrusion 33 cooperating with the limiting groove b.

[0064] For further information, see Figure 4 In this embodiment, a convex rib structure 34 is provided on the cover body 3. The convex rib structure 34 can increase the rigidity and strength of the cover body 3, making it more able to withstand external pressure and extrusion force, thereby improving the stability and durability of the overall product.

[0065] For further information, see Figure 3 In this embodiment, a partition 35 is extended from one side of the cover body 3 toward the bottom of the box body 1. Thus, by providing the partition 35, the accommodating cavity formed by the cover body 3 and the box body 1 can be divided into a plurality of interconnected sub-cavities by the partition 35.

[0066] The partition 35 divides the accommodating chamber into a plurality of chambers. The water is restricted by the partition 35 and moves in a controlled manner between the chambers, thereby limiting the free flow space of the water in the chamber and reducing the possibility of the water shaking in the box body 1.

[0067] Furthermore, in this embodiment, the partition 35 abuts against the bottom of the box body 1. In this way, the partition 35 not only plays the role of partitioning the cavity, but also plays the role of support to ensure the flatness of the cover 3. At the same time, because the partition 35 and the cover 3 are integrally formed, the strength of the cover 3 is also stronger.

[0068] For further information, see Figure 2 and Figure 3 In this embodiment, the water box assembly 100 further includes a sealing portion 6 disposed between the periphery of the opening a and the cover body 3. The sealing portion 6 can increase the closeness between the cover body 3 and the box body 1, improve the stability of the overall structure, prevent loosening or displacement under the action of external forces, and prevent the water in the box body 1 from leaking from the assembly gap of the cover body 3.

[0069] It should be noted that the sealing portion 6 may be an integrally formed sealing ring, or a sealing structure formed by multiple components. The specific design may be based on actual conditions, and the embodiments of this specification do not limit this.

[0070] Furthermore, in this embodiment, an annular groove 3a is concavely formed on the peripheral side of the cover body 3; the sealing portion 6 includes a sealing ring sleeved on the periphery of the cover body 3, and the sealing ring is installed in the annular groove 3a.

[0071] Installing the sealing ring in the annular groove 3a can provide a tighter seal, because the sealing ring is embedded in the groove and can be better fixed in place, effectively preventing liquid, gas or impurities from penetrating from the joint between the box body 1 and the cover body 3. At the same time, fixing the sealing ring in the annular groove 3a can increase the mechanical stability between the cover body 3 and the box body 1, prevent the sealing ring from falling off or shifting under external impact or vibration, and maintain the sealing effect.

[0072] See also Figure 8 The utility model further proposes a range hood 200, which includes a range hood 200 body and a water box assembly 100. The specific structure of the water box assembly 100 refers to the above embodiment. Since the range hood 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0073] For further information, see Figure 8 and Fig. 9 In this embodiment, the range hood 200 includes a fume hood 7, and the fume hood 7 has a rear side wall 71 and two side walls 72 that are oppositely arranged in the transverse direction. In addition, the fume hood 7 may also have a front side wall that is oppositely arranged in the front-to-back direction to the rear side wall 71, and the front side wall, the rear side wall 71 and the two side walls 72 together define an inner cavity of the fume hood 7.

[0074] It should be noted that the smoke hood 7 is a vital component of the range hood 200. 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 7 to allow smoke to enter the smoke hood 7.

[0075] In one embodiment, in order to improve the flow efficiency of the intake air duct, the rear side wall 71 is provided with a guide member 8 extending in the vertical direction. By providing the guide member 8 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.

[0076] Specifically, the guide member 8 can be completely fixed. Specifically, the guide member 8 includes an upper rectifying portion 81 and a lower rectifying portion 82 which are sequentially arranged along the up-down direction. The upper rectifying portion 81 and the lower rectifying portion 82 are both fixedly mounted on the rear side wall 71 of the smoke hood 7, wherein the upper rectifying portion 81 contacts the cavity wall of the inner cavity on opposite sides in the front-to-back direction of the smoke hood 7, respectively, and the upper rectifying portion 81 is formed with rectifying side surfaces on opposite sides in the left-to-right direction of the smoke hood 7, 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 81 of the guide member 8, 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 200; and because the upper rectifying part 81 can rectify the oil smoke into an approximately parallel manner to enter the exhaust port, the probability of the 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 200. Furthermore, because the flow rate of the 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 200.

[0077] Of course, the upper rectifying portion 81 of the guide member 8 can also be movably arranged. Specifically, the lower rectifying portion 82 is fixedly installed on the rear side wall 71 of the smoke hood 7, and the upper rectifying portion 81 is arranged to swing laterally, so that under the swing of the upper rectifying portion 81, the cross-sectional area size in the left and right air inlet paths of the range hood 200 changes, and the air intake ratio on the left and right sides is changed.
