Description

Wall-mounted air conditioner indoor unit and air deflector thereof

Technical Field

The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit and an air deflector thereof.

Background

The air outlet of the wall-mounted air conditioner indoor unit is usually in a horizontally and transversely extending strip shape, and a strip-shaped air deflector is arranged at the air outlet and can rotate around a horizontally and transversely extending axis so as to adjust the up-and-down air outlet direction of the air outlet.

As shown in fig. 1 and 2, the air deflector 40 generally has a plurality of hinge portions 41 arranged along a longitudinal direction thereof, the hinge portions 41 being provided with shafts (or holes), and the housing 30 being correspondingly provided with a plurality of mounting portions 31 having holes (or shafts). The positions of the hinge portions 41 and the mounting portions 31 are in one-to-one correspondence. When the air deflector 40 is installed, one shaft needs to be inserted into the corresponding opening, and then the air deflector 40 is bent, so that the other shafts can be inserted into the corresponding openings.

However, this assembly is very laborious. Moreover, after the air deflector is bent by force, the original shape of the air deflector cannot be recovered in time, which affects the refinement of the appearance of the air deflector and the service life of the air deflector. If the air deflector is short in length and not easy to deform, the assembly is more difficult.

Disclosure of Invention

The present invention is directed to a wall-mounted indoor unit for an air conditioner and a louver thereof, which overcome or at least partially solve the above-mentioned problems, and which do not require bending the louver during installation.

Another object of the present invention is to simplify the installation of the air deflection panel.

It is a further object of the invention to improve the positioning accuracy of the first body and the second body.

In one aspect, the present invention provides an air deflector for a wall-mounted air conditioner indoor unit, comprising:

the first body is provided with a first hinge part and is used for being hinged to a shell of the wall-mounted air conditioner indoor unit, and the first body is provided with an inserting cavity which is inwards formed from the end part of the first body in the length direction; and

the second body is provided with a second hinge part for being hinged to the shell, and one end of the second body in the length direction can be inserted into the insertion cavity in a translation mode along the length direction of the first body, so that the distance between the first hinge part and the second hinge part can be adjusted.

Optionally, at least one side surface of the second body is formed with one positioning tooth or a plurality of positioning teeth arranged at intervals in the length direction of the second body; a tooth socket or a plurality of tooth sockets arranged at intervals in the length direction of the first body is arranged on the side wall of the inserting cavity opposite to the positioning teeth and is used for being meshed with the positioning teeth, so that the relative position of the second body and the first body is restrained; and the first body and the second body are made of elastic materials so as to generate elastic deformation when the first body and the second body are subjected to external force to reach a preset threshold value, and the positioning teeth and the tooth grooves are disengaged.

Optionally, the positioning teeth are arranged on one side surface in the thickness direction of the second body, and each positioning tooth is an elongated strip extending along the width direction of the second body; and each tooth groove is a long strip extending along the width direction of the first body.

Optionally, each gullet forms a through-hole through a sidewall of the plugging cavity.

Alternatively, the positioning teeth are provided on both side surfaces in the width direction of the second body, and each positioning tooth is an elongated shape extending in the thickness direction of the second body.

Optionally, the gullet forms a through hole through a sidewall of the plugging cavity.

Optionally, the positioning teeth are protruding ribs protruding from the side surface of the second body, and two sides of the protruding ribs in the width direction are slope surfaces respectively.

Optionally, the number of positioning teeth and tooth slots is multiple.

Optionally, the air deflector is configured to enable surfaces of the second body and the first body on the same side to be flush with each other after the second body and the first body are inserted.

In another aspect, the present invention further provides a wall-mounted air conditioner indoor unit, which includes a casing having an air outlet formed therein; and at least one air deflector as described in any one of the above, which is located at the air outlet, and the first hinge portion and the second hinge portion of the air deflector are respectively connected to the housing in a rotatable manner around the same axis, so as to allow the air deflector to rotatably guide the air outlet direction of the air outlet.

In the air deflector for the wall-mounted air conditioner indoor unit, the air deflector is formed by splicing a first body and a second body, and the first body and the second body are respectively provided with a first hinge part and a second hinge part which are rotatably connected with a shell. The second body can be inserted into the first body in a translational mode along the length direction of the first body, and therefore the distance between the first hinge portion and the second hinge portion can be adjusted. When an assembler installs the air deflector, the distance between the first hinge part and the second hinge part can be reduced, then the first hinge part is installed on the corresponding installation part on the shell, the second body is pulled outwards to increase the distance between the first hinge part and the second hinge part, so that the second hinge part is close to the corresponding installation part on the shell, and finally the connection between the second hinge part and the corresponding installation part is completed. Therefore, the air deflector does not need to be bent, the operation is very simple and labor-saving, and the adverse effect on the appearance and the service life of the air deflector caused by the bending of the air deflector is avoided.

Furthermore, in the air deflector, the first body is provided with the inserting cavity, and one section of the second body in the length direction is inserted into the inserting cavity, so that the first body and the second body can be telescopically connected. The invention designs the unique inserting structure, after the second body is inserted into the first body, the surfaces of the second body and the first body which are positioned on the same side are flush with each other, and the appearance of the air deflector is more attractive. Moreover, the second body is restrained by the inserting structure in multiple dimensions, so that the position of the second body in the first body is more stable.

Furthermore, in the air deflector, the first body and the second body are meshed through the positioning teeth and the tooth grooves to restrict the relative positions of the first body and the second body to a certain degree, so that the first body and the second body are connected more tightly and stably, the second body is prevented from loosening and shaking from the inserting cavity of the first body, and the positioning accuracy of the first body and the second body is higher. Because first body and second body are made by elastic material to can produce elastic deformation when the external force that both received reaches preset threshold value and make positioning tooth and tooth's socket break away from the meshing. This arrangement can have the following effects: the operator can apply enough pushing force or pulling force to adjust the relative position of the first body and the second body (i.e. adjust the distance between the first hinge and the second hinge). And, after the regulation, when not having enough big exogenic action, the relative position of first body and second body keeps firm, can not appear loosening.

The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

Fig. 3 is a schematic view illustrating a state of the air deflection plate 20 in a process of being mounted to the casing 10 according to an embodiment of the present invention; fig. 4 is a schematic view illustrating a state in which the air guide plate 20 shown in fig. 3 is mounted on the casing 10. Fig. 3 and 4 are the connection relationship between the air guiding plate 20 and the casing 10, and only a part of the casing 10 and the air guiding plate 20 are shown, and the rest of the casing 10 and the rest of the components of the indoor unit are not shown.

The air deflector 20 of the embodiment of the invention is used for being installed at the air outlet 12 of the wall-mounted air conditioner indoor unit and adjusting the air outlet direction of the air outlet 12. For example, as shown in fig. 3 and 4, the air deflector 20 can rotate around the x axis extending horizontally and transversely to adjust the upward and downward air outlet directions of the air outlet 12.

As shown in fig. 3 and 4, the air deflection plate 20 of the embodiment of the present invention may generally include a first body 100 and a second body 200. The first body 100 and the second body 200 both constitute a main body of the air guide plate 20 and both perform an air guide function. The first body 100 has a first hinge portion 120 thereon, and the first hinge portion 120 is adapted to be hinged to the housing 10. The second body 200 has a second hinge part 220 thereon, and the second hinge part 220 is adapted to be hinged to the housing 10. Specifically, the housing 10 has two mounting

portions

13, 14 thereon. The first hinge portion 120 has a first shaft 121 thereon and the second hinge portion 220 has a second shaft 221 thereon. The two mounting

portions

13, 14 are each apertured to mate with the first shaft 121 and the second shaft 221, respectively. Of course, in some alternative embodiments, the first hinge portion 120 and the second hinge portion 220 may be drilled separately, and the two mounting

portions

13 and 14 may be provided with shafts respectively, so as to achieve shaft hole matching. It will be appreciated that the hinge axis of the first hinge portion 120 and the hinge axis of the housing 10 and the hinge axis of the second hinge portion 220 and the housing 10 are collinear (both marked as x-axis in fig. 3) and parallel to the length direction of the air deflection plate 20, so that the air deflection plate 20 as a whole can rotate around the hinge axis (x-axis).

FIG. 5 is another angular view of the deflector 20 of FIG. 3; FIG. 6 is an exploded view of the air deflection plate 20 of FIG. 5; FIG. 7 is an enlarged view at A of FIG. 6; fig. 8 is a schematic cross-sectional view of the plug portion of the air deflection panel 20 shown in fig. 3.

As shown in fig. 5 to 8, the first body 100 has an insertion cavity 130 opened inward from an end of the first body in the length direction, and one end of the second body 200 in the length direction (the length direction of the first body 100 and the second body 200 is the length direction of the air deflector 20, which is parallel to the x axis of the hinge axis) can be inserted into the insertion cavity 130 in a translational manner along the length direction of the first body 100, so as to connect the first body 100 and the second body 200, and adjust the distance between the first hinge part 120 and the second hinge part 220.

In the embodiment of the present invention, the second body 200 can be inserted into the first body 100 in a translational manner along the length direction of the first body 100, so that the distance between the first hinge portion 120 and the second hinge portion 220 is adjustable. When the assembling person installs the wind deflector 20, the distance between the first hinge portion 120 and the second hinge portion 220 can be reduced, and then the first hinge portion 120 is installed on the corresponding installation portion 13 of the housing 10, referring to fig. 3. The second body 200 is pulled out to increase the distance between the first hinge portion 120 and the second hinge portion 220, so that the second hinge portion 220 is close to the corresponding mounting portion 14 of the housing 10, and finally the connection between the second hinge portion 220 and the corresponding mounting portion 14 is completed, referring to fig. 4. Therefore, the air deflector 20 does not need to be bent, the operation is very simple and labor-saving, and the adverse effect on the appearance and the service life of the air deflector 20 caused by the bending of the air deflector 20 is avoided.

In the embodiment of the present invention, the second body 200 is constrained by inserting the second body 200 into the insertion cavity 130 of the first body 100, so that the position of the second body 200 in the first body 100 is more stable and cannot be easily separated from the first body 100, thereby facilitating the installation process and avoiding the unfavorable bending deformation at the connection position due to the unstable connection between the second body 200 and the first body 100 when the air conditioner is in operation.

The air deflection panel 20 may be further configured to: after the second body 200 and the first body 100 are inserted, the surfaces of the two bodies on the same side are flush with each other. That is, the width and thickness of the insertion portion of the second body 200 are made smaller than those of the first body 100 so as to be inserted into the insertion cavity 130, and just two air guide surfaces (i.e., two side surfaces in the thickness direction (z direction) of the second body, which are also the surfaces having the largest area) of the second body 200 are made flush with those of the first body 100, and both end surfaces in the width direction (y direction) of the second body 200 are made flush with both end surfaces in the width direction of the first body 100.

In some embodiments, as shown in fig. 5 to 8, at least one side surface of the second body 200 may be formed with one positioning tooth 240 or a plurality of positioning teeth 240 (a plurality of positioning teeth are illustrated) arranged at intervals in a length direction of the second body 200. Correspondingly, the side wall of the plugging cavity 130 opposite to the positioning teeth 240 is provided with one spline 140 or a plurality of splines 140 (a plurality of splines are illustrated in the figure) arranged at intervals in the length direction of the first body 100, so as to be engaged with the positioning teeth 240, thereby restricting the relative position of the second body 200 and the first body 100. That is, the positioning teeth 240 are engaged with the teeth grooves 140 to apply resistance to the insertion or extension movement of the second body 200 into or out of the first body 100. Moreover, the positioning accuracy of the first body 100 and the second body 200 is higher due to the meshed structure, so that the connection between the first body 100 and the second body 200 is more tight and stable, and the second body 200 is prevented from loosening and shaking from the insertion cavity 130 of the first body 100.

The first body 100 and the second body 200 may be made of an elastic material (i.e., a material that is elastically deformed when an external force is applied thereto and returns to its original state when the external force is removed, such as a hard plastic), so that the positioning teeth 240 and the tooth grooves 140 are elastically deformed when the external force applied thereto reaches a predetermined threshold value. That is, although the engagement of the positioning teeth 240 and the splines 140 restricts the relative positions of the first body 100 and the second body 200, when a sufficiently large pulling or pushing force is applied to the second body 200, the positioning teeth 240 and the splines 140 are forced to disengage, thereby forcibly moving the second body 200 to change the depth of insertion into the first body 100. After the adjustment is completed, when there is not enough external force, the relative position of the first body 100 and the second body 200 is kept stable, and the loosening does not occur.

Preferably, as shown in fig. 3 to 8, the number of the positioning teeth 240 and the tooth grooves 140 is made plural, so that a plurality of engagements are formed at the same time. It will be appreciated that the number of positioning teeth 240 may be one and the number of gullets 140 may be plural to form one engagement. Alternatively, the number of the teeth grooves 140 may be one, and the number of the positioning teeth 240 may be plural, thereby forming one mesh.

Only one side of the second body 200 may be provided with the positioning teeth 240, and two, three, or four sides of the second body 200 may be provided with the positioning teeth 240.

For example, in the embodiment shown in fig. 3 to 8, the positioning teeth 240 are provided on one side surface in the thickness direction (z direction) of the second body 200, and each positioning tooth 240 is an elongated shape extending in the width direction of the second body 200. Correspondingly, each of the slots 140 is an elongated shape extending in the width direction of the first body 100. The positioning teeth 240 and the tooth grooves 140 are long, so that the contact surface between the positioning teeth and the tooth grooves is larger, and the restraint is stronger.

As shown in fig. 7 and 8, each spline 140 penetrates a sidewall of the plugging chamber 130 to form a through hole. This structure facilitates the design and manufacture of the first body 100. Also, the through-hole shaped splines facilitate elastic deformation of the first body 100. In addition, when a failure occurs in which the positioning teeth 240 are locked to the gullets 140, the positioning teeth 240 may be pushed by a tool inserted into the through-hole-shaped gullets 140 to be disengaged from the gullets 140, thereby releasing the locking. Of course, in some alternative embodiments, the gullet 140 may not penetrate the sidewall of the plugging cavity 130.

As shown in fig. 7 and 8, the positioning teeth 240 may be ribs protruding from the side surface of the second body 200, and both sides of the ribs in the width direction may be slope surfaces. The positioning teeth 240 and the tooth grooves 140 are contacted through the slope surfaces, and when the external force is large enough, the positioning teeth and the tooth grooves are favorable for guiding the positioning teeth and the tooth grooves to be disengaged, so that the operator is prevented from doing too much labor.

Fig. 9 is a schematic structural view of an air deflector according to another embodiment of the present invention; FIG. 10 is an exploded view of the deflector of FIG. 9; fig. 11 is an enlarged view of fig. 10 at B.

In the embodiment shown in fig. 9 to 11, the positioning teeth 240 are provided on both lateral sides in the width direction of the second body 200, and each positioning tooth 240 is an elongated shape extending in the thickness direction of the second body 200. The tooth grooves 140 are opened on both side walls of the insertion cavity 130 corresponding to the positioning teeth 240. Since the areas of both lateral sides in the width direction of the second body 200 are small, the positioning teeth 240 are disposed thereon, and the influence on the appearance of the air deflection plate 20 is small. And, in order to secure sufficient constraint, positioning teeth 240 are provided at both sides of the width direction of the second body 200.

As shown in fig. 9 and 10, each spline 140 may penetrate through a sidewall of the socket cavity 130 to form a through hole, similarly to the previous embodiment, to facilitate design and processing of the first body 100. Also, the through-hole shaped splines facilitate elastic deformation of the first body 100. In addition, when a failure occurs in which the positioning teeth 240 are locked to the gullets 140, the positioning teeth 240 may be pressed by a tool inserted into the through-hole-shaped gullets 140 to be disengaged from the gullets 140, thereby releasing the locking. In some alternative embodiments, the gullet 140 may not penetrate the sidewall of the plugging cavity 130.

In addition, the positioning teeth 240 may be ribs protruding from the side surface of the second body 200, and both sides of the ribs in the width direction are slope surfaces. The positioning teeth 240 and the tooth grooves 140 are contacted through the slope surfaces, and can be guided to be disengaged when the external force is large enough, so that the excessive labor of an operator is avoided. The embodiment of the invention also provides a wall-mounted air conditioner indoor unit. Referring to fig. 3, a wall-mounted air conditioning indoor unit generally includes a casing 10 and a wind deflector 20 according to any of the above embodiments. The housing 10 is formed with an air outlet 12. The air deflector 20 is disposed at the air outlet 12, and the first hinge portion 120 and the second hinge portion 220 thereof are respectively rotatably connected to the housing 10 around the same axis (x-axis), so as to allow the air deflector 20 to rotatably guide the air outlet direction of the air outlet 12.

Specifically, a wall-mounted air conditioning indoor unit is an indoor unit of an air conditioning system that performs cooling/heating by a vapor compression refrigeration cycle system. An air inlet can be formed in the shell 10, a heat exchanger and a fan are arranged in the shell 10, under the action of the fan, indoor air enters the shell 10 from the air inlet and exchanges heat with the heat exchanger to form cold air or hot air, and the cold air or the hot air is guided to the air outlet 12 through an air duct and is blown back to the room for cooling or heating.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
