Abstract

PURPOSE:To prevent the blowing capacity of an air-conditioning device from decreasing by a holding mechanism under a curved condition by a method wherein an engaging member is connected to a shaft attaching part of a link from the outer surface side of an air outlet, and a turn regulating member, which regulates the motion of the engaging member which turns together with the link, by friction resistance, is engaged with the engaging member on the outer surface side of the air outlet. CONSTITUTION:On the outer surface side of a bottom wall 3b of an air outlet 3, an engaging plate 20 as an engaging member is arranged, and an engaging protuberance 20a which is formed on the upper surface is fitted to be fixed in an engaging hole 12b of a link 12. For this reason, the link 12 and engaging plate 20 turn around an axis L as the center. Also, on the outer surface side of the bottom wall 3b of the air outlet 3, fastening claws 22 as turn regulating members are arranged in a row. Since the engaging plate 20 which turns in response to the curved condition of air direction deflecting boards 4a, 4b and the fastening claws 22 which regulate the turning are provided on the lower side of the air outlet 3, a desired air blowing-out angle can be always obtained by holding the curved condition of the air direction deflecting boards 4a, 4b, and in addition, even when blowing-out air temperature is changed, the curved condition of the air direction deflecting boards 4a, 4b can be assuredly kept. Also, the engaging plate 20 or fastening claws 22 are not provided in the air outlet 3, the blowing capacity of an air-conditioner can be prevented from reducing.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an air conditioning grill, and more specifically, it is provided in an air conditioner that air-conditions the interior of a house or vehicle, and blows hot or cold air into the interior of the vehicle. This relates to an air conditioning grill that blows out air.

[Conventional technology]

Conventionally, air-conditioning creels for air conditioners have been made by bending an elastic wind deflection plate made of rubber or resin into an arc shape inside the outlet using a control lever to control the direction of the wind introduced into the room through the outlet. There are known devices that are modified as appropriate.

Since the wind direction deflection plate of the above-mentioned air conditioning grill has elasticity, it has a property that even if it is bent by the operation lever, it returns to the original curved state. Therefore, as in the air conditioning grill described in Utility Model Application Publication No. 1-123151 (shown in FIG. 8), a large number of latching claws 43 are arranged in an arc shape on the inner wall of the air outlet 42 corresponding to the operating lever 41. By hooking the protrusion 44 formed on the operating lever 41 to the hook 43, the wind direction deflecting plate 4
5 has been proposed in which it is maintained in a predetermined curved state.

In addition, as in the air conditioning grill described in Japanese Utility Model Application Publication No. 1-123150 (shown in FIG. 9), the reaction force of the wind direction deflecting plate 45 (
The tension spring 46
It has also been proposed to maintain the curved state of the wind direction deflecting plate 45 by balancing the biasing forces of the wind direction deflecting plate 45.

[Problem to be solved by the invention]

However, in the two types of air conditioning grilles described above, there is a problem in that the air passing through the air outlet 42 is obstructed by the latch claw 43, the tension spring 46, etc., and the air blowing performance of the air conditioner is reduced.

Furthermore, since the air outlet 42 generally opens toward the interior of the room, there is also the problem that the latch claw 43, tension spring 46, etc. are exposed to the outside, spoiling the aesthetic appearance of the air conditioner.

Furthermore, since the wind direction deflection plate 45 is constantly exposed to the wind passing through the air outlet 42, its hardness changes depending on the blowout temperature, and the reaction force when the wind direction deflection plate 45 is bent also fluctuates. Therefore, in the air conditioning grill using the above-mentioned tension spring 46, when the blowout temperature changes, the wind direction deflection plate 45
There is a risk that the balance between the reaction force of the deflection plate 45 and the biasing force of the tension spring 46 will be lost, and the deflection plate 45 may return to its original state of curvature or become more curved, making it impossible to maintain it in a predetermined curvature state. be.

An object of the present invention is to be able to maintain a wind direction deflection plate in a predetermined curved state regardless of changes in blowout temperature, and to prevent the blowing performance of an air conditioner from deteriorating by a mechanism that maintains the curved state. It is an object of the present invention to provide an air conditioning grill that can prevent the appearance of an air conditioner from deteriorating due to its mechanism.

[Means to solve the problem]

In the present invention, a plurality of bendable wind deflection plates are disposed within an air outlet, one end of each wind deflection plate is rotatably pivoted within the air outlet, and the other end is connected to each other by a connecting member. connect,
One end of the link is rotatably attached to the pivot point of one of the wind deflection plates, the other end is connected to the connecting member, and the link is rotated to move the connecting member, and each of the wind deflectors In an air conditioning grill that changes the curvature of the plate,
An engaging member is connected to the shaft attachment point of the link from the outer surface side of the air outlet, and a rotation regulating member that restricts the movement of the engaging member that rotates together with the link by frictional resistance is connected to the outer surface of the air outlet. The gist of this invention is an air conditioning grill that is engaged with an engaging member on the side.

[Effect]

Each wind direction deflection plate is curved in accordance with the rotational operation of the link, and accordingly, the direction of hot air or cold air blown out from the inside of the air outlet is changed. The wind deflection plate thus curved uses its own elasticity to rotate the link in the opposite direction in an attempt to return to its original curved state, but at this time the movement of the engagement member is restricted by the rotation restriction member using frictional resistance. Therefore, rotation of the links is prevented and each wind deflection plate is maintained in a predetermined curved state.

Since the above-mentioned wind direction deflection plate is constantly exposed to the wind passing through the air outlet, its hardness changes depending on the air outlet temperature. Therefore, the reaction force when the wind deflection plate is curved also fluctuates, but in the present invention, if the engagement force of the rotation regulating member with respect to the engagement member is set strong in advance, the reaction force of the wind deflection plate is large. This makes it possible to maintain the curved state at all times, even when it is small or small.

Further, since the engaging member and the rotation regulating member are provided on the outer surface side of the air outlet, that is, on the outside of the air outlet, these members do not obstruct the wind passing through the air outlet.

Furthermore, although the air outlet is generally open toward the outside,
Since no engaging member or rotation regulating member is provided within the air outlet, the aesthetic appearance of the air conditioner is not spoiled.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment in which the present invention is embodied in an air conditioning grill for a residential air conditioner will be described with reference to the drawings.

FIG. 2 is a perspective view of the air conditioner, FIG. 1 is a side sectional view of an air conditioning grill provided in the air conditioner, and FIG. 3 is a partially exploded perspective view of the air conditioning grill. As shown in these figures,
The air conditioning grill 1 is provided at the lower front of the air conditioner 2, and hot air or cold air is blown into the room from the air conditioning grill 1. The air outlet 3 of the air conditioning grill 1 is integrally molded from synthetic resin, and a number of plate-shaped wind deflection plates 4a and 4b (only two are shown in FIG. 3) are disposed inside the air outlet 3. It is set up. This wind direction deflection plate 4a
, 4b has its front part (left side in Fig. 1.3) and rear part (
(right side in Figures 1 and 3) are the front and rear rigid parts 5 and 6.
The space between them is a bendable soft part 7. The rigid parts 5 and 6 are made of polypropylene, ABS resin, etc., and the soft part 7 is made of elastomer, rubber, etc.

As shown in FIG. 3, the wind direction deflecting plate 4a.

A support hole 8 is formed at the upper end of the front rigid part 5 of 4b,
A rotation shaft 9 protruding from the upper wall 3a of the air outlet 3 is fitted into the support hole 8. Further, a rotating shaft 10 is provided protruding from the lower end of the front rigid portion 5, and each rotating shaft 10 is connected to the lower wall 3 of the air outlet 3.
b (wind direction deflection plate 4b on the right side of FIG. 3). Therefore, each wind direction deflection plate 4b can be rotated about the axis connecting the support hole 8 and the rotation shaft 10.

Moreover, as shown in FIGS. 1 and 3, the wind direction deflection plates 4a, 4
Any two of b (the wind deflection plate 4a on the left side in FIG. 3) have their rotational axes lO located in the support holes 13 of the links 12 disposed below the wind deflection plate 4a. It is inserted. A rotation shaft 14 is formed on the lower surface of the link 12, and the rotation shaft 14 is fitted into a support hole 15 formed in the lower wall 3b of the air outlet 3. Therefore, this wind direction deflecting plate 4a
is rotatable about the axis like the other deflecting plate 4b described above, and the link 12 is also rotatable about the axis.

A notch 16 is formed in the lower part of the rear rigid part 6 of each of the wind direction deflection plates 4a, 4b, and a rod-shaped connecting member 17 is fitted and fixed in the notch 16, and The rigid parts 6 are connected to each other.

A locking hole 18 is formed in the connecting member 17, and a pin 12 formed at the rear end of the link 12 is inserted into the locking hole 18.
A is inserted. Further, an operating lever 19 is integrally formed at the front end of the link 12 so as to protrude from the inside of the air outlet 3 toward the front (indoor side).

When the operating lever 19 is rotated, the link 12 rotates about the axis, and the connecting member 17 moves left and right. As a result, the rear rigid part 6 of each wind deflection plate 4a, 4b moves left and right, the front rigid part 5 rotates about the axis, and the soft part 7 between them moves in a predetermined direction. curved at an angle.

On the other hand, FIG. 4 is a bottom view of the air conditioning grill l.

As shown in FIG. 4 and FIGS. 1 and 3, the link 12
The rotation shaft 14 is exposed on the outer surface side of the lower wall 3b of the air outlet 3,
A rectangular engagement hole 12b is formed in the end face. Further, an engagement plate 20 serving as a substantially triangular engagement member is disposed on the outer surface side of the lower wall 3b of the air outlet 3.
A quadrangular prism-shaped engagement protrusion 20a formed on the upper surface of the link 12 is fitted and fixed into the engagement hole 12b of the link 12. Therefore, together with the link 12, the engagement plate 20 also rotates about the axis.

Further, a projection 21 is formed on the upper surface of the engagement plate 20, and a locking pawl 22 as a rotation regulating member is circularly formed on the outer surface of the lower wall 3b of the air outlet 3 so as to correspond to the projection 21. They are arranged in an arc. The protrusion 21 of the engagement plate 20 is always fitted between any adjacent latching claws 22, and the frictional resistance generated between the protrusion 21 and the latching claw 22 prevents rotation of the engagement plate 20. regulated. Furthermore, when the engagement plate 20 rotates as described above, the position at which the protrusion 21 engages with the engagement claw 22 is changed.

Next, a case will be described in which the blowing angle of the air conditioning grill 1 configured as described above is changed.

When the operating lever 19 is rotated left and right, the rotation angle of the link 12 is changed and the connecting member 17 is moved left and right.

Therefore, the rear rigid part 6 of each wind deflection plate 4a, 4b moves left and right, the front rigid part 5 rotates about the axis, and the soft part 7 between them moves in a predetermined direction at a predetermined angle. curved to.

As a result, the angle of hot air or cold air blown into the room from the air outlet 3 of the air conditioning grill 1 is changed.

Further, when the link 12 is rotated by the operation lever 19 as described above, the engagement plate 20 is also rotated together with the link 12. Therefore, the protrusion 21 of the engagement plate 20 moves slightly up and down on each of the locking claws 22 to change the locking position. The curved wind deflection plates 4a and 4b tend to return to the neutral position, that is, the uncurved state shown in FIG. 3, due to their own elasticity. Since the portion 21 is latched to the latching claw 22, the wind direction deflecting plates 4a, 4b are held in a predetermined curved state.

By the way, there is a considerable temperature difference in the air outlet temperature of the air conditioner 2 in this embodiment between heating and cooling. Since the wind direction deflecting plates 4a and 4b are constantly exposed to the wind passing through the air outlet 3, their hardness changes depending on the air blowing temperature. Therefore, the reaction force when the wind direction deflection plates 4a, 4b are bent also changes.In the present invention, the engagement force between the protrusion 21 of the engagement plate 20 and the latching claw 22 is adjusted in advance to the wind direction deflection plates 4a, 4b. If the reaction force is set higher than the reaction force, the wind direction deflection plate 4a.

It becomes possible to always maintain the curved state whether the reaction force of 4b is large or small.

Further, since wind passes through the air outlet 3 of the air conditioning grill 1, it is not preferable if an obstacle is provided inside the air outlet 3 because the amount of air blown will decrease. In the air conditioning grill 1 of this embodiment, as described above, the engaging plate 20 and the latch claw 22 are
Since these members 20 and 22 are provided below (outside) the air outlet 3, these members 20, 22 are prevented from interfering with the passage of air within the air outlet 3.

Furthermore, as shown in FIG. 2, although the air outlet 3 opens toward the interior of the room, since the engaging plate 20 and the latch claw 22 are not provided inside the air outlet 3, these members 20. 22
is not exposed indoors.

In this way, the air conditioning grill of this embodiment has the wind direction deflecting plate 4a.
, 4b, and a locking claw 22 for regulating the rotation of the engaging plate 20 are provided on the lower side (outside) of the air outlet 3.

Therefore, it is possible to maintain the curved state of the wind direction deflection plates 4a and 4b to always obtain a desired blowout angle, and even when the blowout temperature changes, the wind direction deflection plates 4a.

The curved state of 4b can be maintained reliably.

Furthermore, since neither the engaging plate 20 nor the latch claw 22 is provided inside the air outlet 3, these members 20, 22 are prevented from interfering with the air passing through the air outlet 3, and the air blowing capacity of the air conditioner 2 is reduced. Can you prevent the decline?

Furthermore, since the engaging plate 20 and the latching claw 22 are not provided inside the air outlet 3, it is possible to prevent these members 20, 22 from being exposed to the outside and deteriorating the aesthetic appearance of the air conditioner 2. I can do it.

Note that the present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned embodiment, the protrusion 21 of the engagement plate 20 is connected to the latching claw 2.
Although the curved state of the wind direction deflection plates 4a and 4b is maintained by hooking them to the wind deflection plates 2 and 2, a configuration using frictional force may be adopted as shown in FIGS. 5 and 6. That is, a disk-shaped friction plate 31 as an engaging member is attached to the link 12, and a friction spring 32 as a rotation regulating member is attached to the outer periphery of this friction plate 31.
．． 33 are brought into pressure contact, and due to the frictional force generated between the friction plate 31 and the friction spring 32 or between the friction plate 31 and the friction spring 33,
The rotation of the friction plate 31 may be restricted to maintain the curved state of the wind direction deflection plates 4a and 4b. In this separate case, the friction plate 31 is made of abrasion-resistant polypropylene (PP), and the friction springs 32, 33 are made of polyacetal resin (POM), spring steel, or the like.

Further, as shown in FIG. 7, the front wall of the friction plate 31 described above is used as a friction surface 34 as a rotation regulating member, and the outer periphery of the friction plate 31 is pressed against the friction surface 34 to form the wind direction deflection plate 4.
It may also be maintained in the curved states a and 4b.

Further, in the above embodiment, the engaging plate 20 and the catch pawl 22 are provided at the lower side of the outlet 3, but for example, the upper side of the outlet 3, that is, the drain groove 35 for discharging water condensed on the evaporator. (as shown in FIG. 1).

[Effects of the Invention] As detailed above, according to the air conditioning grill of the present invention, the wind direction deflection plate can be maintained in a predetermined curved state regardless of changes in the blowout temperature, and the curved state can be maintained. The mechanism prevents the blowing performance of the air conditioner from deteriorating, and the mechanism also prevents the appearance of the air conditioner from deteriorating, which is an excellent effect.
