Referring to fig. 1 to 4, a range hood 100 according to an embodiment of the present application includes a main body 10 and a cabinet 30. The main body 10 is formed with a mounting opening S, and the cabinet 30 is partially nested in the mounting opening S of the main body 10 in the assembly direction (corresponding to the X direction in fig. 3). The range hood 100 further includes a positioning structure 50, where the positioning structure 50 is disposed on at least one of the main body 10 and the cabinet 30, and is configured to limit the cabinet 30 in the assembly direction.

The range hood 100 is not generally integrally formed, but is assembled by at least two parts of the main body 10 and the cabinet 30, because the whole range hood is large in size and has a certain complexity. In a normal use state, the cabinet 30 of the range hood 100 is located above, which may be a wind cabinet, and is used for installing a fan. The main body 10 is located below the cabinet 30 for mounting a main board, forming an operation panel, etc., and the main body 10 forms a smoke suction port for sucking smoke. In addition, the mounting opening S of the main body 10 naturally faces the cabinet 30, i.e., is disposed upward, and has a shape matching that of the cabinet 30.

It will be appreciated that the main body 10 and the cabinet 30 need to be assembled as different parts of the range hood 100 during the production or installation of the range hood 100. When the main body 10 and the cabinet body 30 are assembled, the cabinet body 30 is first close to the main body 10 along the assembly direction and is partially nested in the mounting port S of the main body 10, the assembly path is shown by the broken line in fig. 3 and 4, and then the main body 10 and the cabinet body 30 are connected by means of screw connection, riveting, welding, and the like.

The positioning structure 50 is capable of limiting the cabinet 30 in the assembly direction, i.e., preventing the cabinet 30 from being excessively nested into the mounting opening S. The assembly direction may be a height direction, i.e. a gravity direction, and the cabinet 30 may be moved downward in the mounting opening S under the action of gravity until limited by the positioning structure 50, at which point the cabinet 30 is already assembled in place in the mounting opening S.

The positioning structure 50 may be, but is not limited to, a clip, a positioning protrusion, a positioning pin, etc., and is not limited to, but is capable of limiting movement of the cabinet 30 in the assembly direction.

In the above-described range hood 100, when the main body 10 and the cabinet 30 are assembled, the main body 10 is formed with the mounting opening S, and the cabinet 30 is partially fitted into the mounting opening S, so that the cabinet 30 is horizontally positioned by being limited by the mounting opening S. In addition, the limiting cabinet 30 is also limited in the assembly direction by the positioning structure 50, and is positioned in the assembly direction. So, when carrying out nested installation to the cabinet body 30, need not to be with the help of the spacing frock of extra complicacy, the installation mouth S cooperation location structure 50 of main part 10 just can make the location of high-efficient and accurate to the position of cabinet body 30 to after the location, accomplish the connection of main part 10 and cabinet body 30.

In some embodiments, the range hood 100 is an air-conditioning range hood, and includes a hood module for implementing fume extraction and an air-conditioning module for temperature adjustment, wherein a heat exchanger, a compressor, etc. of the air-conditioning module may also be installed in the cabinet 30.

As a combined product, the air-conditioning type range hood has a more complex structure, and assembly between parts is difficult to avoid. Therefore, the mounting port S is utilized to cooperate with the positioning structure 50 to position the assembly of the cabinet 30, which is helpful to improve the production efficiency and the product qualification rate of the air-conditioning type range hood.

In some embodiments, the main body 10 includes a shroud 11, and the shroud 11 encloses to form a mounting opening S and fits around the perimeter of the cabinet 30. It will be appreciated that the shroud 11 is arranged in a vertical direction with its thickness direction being arranged horizontally.

On the one hand, the mounting opening S formed by the coaming 11 can have a certain depth and height, so that the positioning effect on the cabinet body 30 is better. On the other hand, the coaming 11 can be stably connected to the cabinet 30 by bolts, rivets, or the like.

Referring to fig. 5 to 7, in some embodiments, the positioning structure 50 is a positioning protrusion, and the positioning protrusion is protruding on an outer surface of the cabinet 30 and/or a surface of the main body 10 located in the mounting opening S.

The positioning bulge can be arranged on the outer surface of the cabinet body 30, and after the cabinet body 30 is partially nested in the mounting port S of the main body 10 along the assembly direction and is mounted in place, the positioning bulge is clamped outside the mounting port S, so that a limiting effect is generated on the cabinet body 30, and the cabinet body is prevented from continuously moving downwards in the assembly direction. The positioning protrusion can also be arranged on the surface of the main body 10 located in the mounting port S, and can stop the cabinet body 30 partially nested in the main body 10 from continuously moving downwards in the mounting direction by blocking the positioning protrusion on the mounting path of the cabinet body 30.

In other embodiments, the positioning protrusions may also protrude from the inner surface of the cabinet 30 and/or the surface of the main body 10 located outside the mounting port S. The cabinet body 30 is partially nested and is outside the main body 10, and after the cabinet body 30 is installed in place along the assembly direction, the positioning protrusion has a limiting effect on the cabinet body 30 and prevents the cabinet body 30 from continuously moving downwards in the assembly direction.

In some embodiments, the positioning structure 50 includes a first positioning protrusion 51, and an outer surface of the cabinet 30 is configured to form the first positioning protrusion 51, and the first positioning protrusion 51 abuts against an edge of the mounting port S in the assembly direction to limit the cabinet 30 in the assembly direction.

The first positioning protrusion 51 is protruded on the outer surface of the cabinet 30, and abuts against the edge of the mounting port S in the mounting direction when the cabinet 30 is mounted in place. The first positioning protrusion 51 cannot enter the mounting port S, and cannot be further nested in the mounting port S.

Thus, the cabinet 30 is clamped outside the mounting opening S through the first positioning protrusion 51, the part of the cabinet 30 positioned at one side of the first positioning protrusion 51 is nested in the mounting opening S, and the part of the cabinet 30 positioned at the other side of the first positioning protrusion 51 is positioned outside the mounting opening S. The cabinet 30 cannot continue to move toward the mounting opening S in the assembly direction, and the first positioning protrusion 51 has a positioning effect on the cabinet 30. In other words, the first positioning protrusion 51 supports the cabinet 30 from falling downward under the effect of gravity.

Further, the first positioning projection 51 abuts against the upper edge of the coaming 11 in the fitting direction. The mounting opening S is formed by enclosing the coaming 11, and the edge of the mounting opening S and the upper edge corresponding to the coaming 11 are abutted with the edge of the mounting opening S, that is, the upper edge of the coaming 11.

In some embodiments, the first positioning protrusion 51 is formed with a support plane Z, and the first positioning protrusion 51 abuts against an edge of the mounting port S in the fitting direction through the support plane Z.

The supporting plane Z is a flat geometric surface formed in the same plane, so that the contact area between the supporting plane Z and the edge of the mounting opening S can be increased, and the supporting effect on the cabinet body 30 is enhanced.

Further, the cabinet 30 includes a housing 31, the housing 31 is configured with a horizontal slit Q penetrating in the thickness direction thereof, a portion of the housing 31 located on the upper side of the horizontal slit Q projects in the thickness direction of the housing 31 to form a first positioning projection 51, and the upper side face of the horizontal slit Q forms a support plane Z.

The outer shell 31 is arranged in the vertical direction, the thickness direction thereof is horizontally arranged, the horizontal slit Q may be formed by pre-processing, and the outer shell 31 at the upper part of the horizontal slit Q is protruded by a molding process such as stamping or die pressing, so as to form the first positioning protrusion 51. In other embodiments, the first positioning protrusion 51 may be formed directly by a molding process such as a die pressing or a stamping process, the shell 31 is torn to form the horizontal slit Q, or a processing groove is formed in the corresponding position of the shell 31 in advance, and then the first positioning protrusion 51 is formed by a molding process such as a die pressing or a stamping process, so that the horizontal slit Q is formed by tearing the processing groove, which is not particularly limited herein. After the first positioning protrusion 51 is formed, the upper side surface of the horizontal slit Q protrudes from the lower side surface, so that the upper side surface of the horizontal slit Q forms a supporting plane Z, and the upper side surface of the horizontal slit Q is the lower side surface of the first positioning protrusion 51.

It will be appreciated that the upper and lower sides of the horizontal slit Q refer to the upper and lower sides of the range hood 100 in the height direction of the whole machine in normal use, and the horizontal slit Q and the first positioning protrusion 51 are formed on the peripheral side surface of the housing 31.

In this way, the first positioning protrusion 51 can be formed directly on the outer shell 31 of the cabinet 30 by a simple processing process, and the support plane Z can be formed at the same time. The first positioning boss 51 is integrally formed with the housing 31, no new parts need to be introduced, and the connection relationship is reliable. At the same time, the horizontal notch Q can reduce the probability of unexpected cracking of the housing 31 during processing.

Further, the first positioning protrusion 51 has an arc shape. Preferably, the first positioning protrusion 51 may have a circular arc shape, and may have a quarter spherical structure in particular.

The arc shape is easier to stretch and form, and the structure is stable. It will be appreciated that in other embodiments, the first positioning protrusion 51 may also have a three-dimensional shape such as a cuboid, which is not specifically limited herein.

In some embodiments, the cabinet 30 is formed with first positioning protrusions 51 at least at opposite side outer surfaces, and each side may be formed with two or more first positioning protrusions 51.

It will be appreciated that the opposite outer surfaces of the cabinet 30 may be left and right sides, front and rear sides, as they normally are used.

Thus, the first positioning protrusion 51 can provide a supporting and limiting effect for the cabinet 30 on at least two opposite sides, so that the formed limiting effect is more stable and more accurate.

In some embodiments, the positioning projections include second positioning projections (not shown), and the surface of the main body 10 located in the mounting port S is configured to form the second positioning projections, which abut against the lower edge of the cabinet 30 in the assembly direction.

Specifically, the surface configuration of the shroud 11 toward the mounting opening S forms a second positioning projection. The range hood 100 may have the first positioning protrusion 51 or the second positioning protrusion alone, or may have both the first positioning protrusion 51 and the second positioning protrusion.

The second positioning protrusion can bear the cabinet 30 below when the cabinet 30 is assembled in place, in other words, it is blocked on the assembly path of the cabinet 30, preventing further falling, and achieving the positioning effect.

It will be appreciated that the second positioning protrusion may be generally similar in structure to the first positioning protrusion 51, formed with a support plane Z, and support the lower edge of the cabinet 30 through the support plane Z. The coaming 11 is constructed with a horizontal slit Q penetrating through itself, a portion of the coaming 11 located on the lower side of the horizontal slit Q is protruded to form a second positioning protrusion with respect to a portion located on the upper side of the horizontal slit Q, and the lower side of the horizontal slit Q forms a support plane Z. The second positioning protrusion is arc-shaped. Specifically, the second positioning protrusion is of a quarter sphere structure. The shroud 11 is formed with second positioning projections on at least the outer surfaces of the opposite sides.

In other embodiments, the locating projections are welded to the outer surface of the cabinet 30 and/or the surface of the main body 10 within the mounting opening S. Or the positioning projections are welded to the inner surface of the cabinet 30 and/or the surface of the main body 10 located outside the mounting port S.

In contrast to forming the locating protrusions directly from the surface configuration of the main body 10 or cabinet 30, the welding does not require forming openings or cutouts in the surface of the main body 10 or cabinet 30.

It will be appreciated that in other embodiments, the locating boss may also be secured by staking, bolting, or the like.

The range hood 100 is assembled by assembling the main body 10 and the cabinet 30. Specifically, the cabinet 30 is moved in the assembly direction to be partially nested in the mounting port S of the main body 10. In the assembly process of the cabinet 30, when the cabinet 30 falls to the supporting plane Z of the first positioning protrusions 51 formed on both sides of the housing 31 thereof and the upper edge of the coaming 11 of the main body 10 are abutted, the cabinet 30 is blocked by the abutment of the first positioning protrusions 51 and the coaming 11, and cannot continue to fall. At this time, the cabinet 30 is assembled in place while being positioned in an assembling direction by the horizontal direction in which the main body 10 is formed through the mounting opening S and the support of the first positioning boss 51 in the height direction. After the assembly position of the cabinet 30 is positioned, the coaming 11 can be connected with the shell 31 by means of bolting, riveting, welding and the like to connect the main body 10 and the cabinet 30.

In this way, the assembly process of the cabinet 30 and the main body 10 can efficiently and accurately form positioning without additional limiting tools.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
