Description

Diffuser for air conditioning, with a core height is adjustable spread}

The present invention relates to a diffuser for air conditioning to diffuse the cooling and heating air to be supplied to the room, and more specifically, to adjust the height of the diffuser core for diffusing the cooling and heating air, all diffusers without regard to the shape of the diffuser The present invention relates to an air conditioner diffuser having a diffusion core having an adjustable height so that the airflow of the cooling / heating air supplied to the room is greatly improved and noise is prevented.

In general, a diffuser is installed on the indoor ceiling of a building to diffuse and supply air-conditioning air, and such a diffuser is divided into a diffuser body which serves to diffuse the diffuser body and air.

Therefore, the direction in which the cooling and heating air supplied to the room is changed according to the height of the diffusion core.

Specifically, when the diffusion core is in a raised position in the upper direction, the cooling and heating air is blown in the vertical direction. On the contrary, when the diffusion core is in a lowered position in the lower direction, the cooling and heating air is blown in the horizontal direction to the room. Supplied.

As described above, the blowing direction of the cooling and heating air is changed so that the cooling air is blown in the horizontal direction during summer when the cooling air is supplied so that the cooling air is intensively blown to the person working under the diffuser to prevent the occurrence of cooling bottles. At the same time, since the cold air is moved downward by convection, the cooling air diffused horizontally from the ceiling is circulated to the lower part of the room more quickly.

In the winter when the heating air is supplied, the air is blown in the vertical direction so that the heating air blown toward the lower part of the room is raised in the upper direction by the convection action, so that more rapid indoor heating is achieved.

Therefore, a number of prior art diffusers in which the height of the diffusion core is controlled are disclosed as described in the prior art patent documents.

However, the diffusers of the prior art all have a problem that the height of the diffusion core is controlled in the air inlet hole, which is a narrow passage, which greatly affects the flow of the cooling and heating air, thereby significantly reducing the diffusion function of the cooling and heating air. There is this.

That is, the diffuser has an air inlet hole into which the cooling and heating air supplied from the duct flows, and the diffuser is provided with a diffusion hole embedded in the lower portion of the air inlet hole to diffuse the cooling and heating air. It was provided in the air inlet in this narrow passage state to be able to adjust, so that the airflow of the heating and cooling air was hindered.

Therefore, the air-conditioning air introduced into the air inlet is blown into the diffusion hole and the diffusion core is blown to the diffusion core. At this time, the air inlet hole is blown into the diffusion hole in a state where the blowing force is deteriorated. As the diffusion function is greatly reduced, there is a problem that the performance of the diffuser is caused.

In addition, not only the narrow air inlet is blocked by the height adjusting means, but the flow resistance of the cooling and heating air is largely generated by the height adjusting parts in the air inlet, resulting in a decrease in the blowing force, thereby causing a blowing speed. As a result of the decrease in the amount of air blowing of the cooling and heating air supplied to the room caused a problem.

Therefore, the amount of air-conditioning air supplied to the room is greatly reduced, there is a problem that causes the indoor air-conditioning efficiency is greatly reduced.

And the prior art diffusers have a limited and limited problem that can be carried out only in the circular diffuser in the case of a circular diffuser, in the case of a square diffuser, because the height adjustment is made in the air inlet.

In particular, in the case of the rectangular diffuser proposed in the prior art, there is a problem that the inconvenience and hassle that needs to be reassembled by rotating to 90 ° after separating the diffusion core from the main body.

In addition, the diffusers of the prior art have height adjustment means in the air inlet, which is a narrow passage, so that the wind passing through the narrow passage is hardly hit, so that the parts are finely vibrated by the strong wind, whereby noise is generated. There is a problem.

In order to prevent the noise, the wind flow should be minimized to minimize the wind resistance received by the parts. However, in the narrow air inlet, there is a limited problem that is very difficult. I can't.

Therefore, the diffusers of the prior art solve the vibration noise problem by employing thick parts to minimize the noise, but in this case, the diffuser is installed because the cost of the diffuser is heavy and the cost increases. Since the interior ceiling structure is to be more robust than necessary, it causes economic losses or inefficiencies and further problems caused by the risk of safety accidents.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings.

1 and 2, the present invention includes a main body 10 that is broadly divided into a duct (unsigned) and a diffusion core 30 that diffuses cooling and heating air into the main body 10.

In order to help the understanding of the present invention, air-conditioning air is sometimes described as air or wind.

Therefore, in the present invention, there is an air inlet hole 11 through which the cooling and heating air flows from the duct, and a diffusion hole 12 is provided below the air inlet hole 11.

Since the diffusion hole 12 is installed so that the diffusion core 30 for diffusing the cooling and heating air blown through the air inlet hole 11 toward the interior is included, the air inlet hole 11 is larger than the diffusion hole 12. ) Is relatively very narrow.

Therefore, in the present invention, a pair of fastening means 20, 20 'having at least two or more fastening holes 23, 23', 23 "having different heights is fixed to both sides of the ceiling member 13 of the diffusion hole 12. It is provided.

The pair of binding means (20, 20 ') is fixed to the ceiling member 13 is opposed to each other with the air inlet (11) in the center.

2 and 3, the binding means 20 and 20 ′ have multistage coupling holes 22 and 22 ′ protruding from both ends of the fixing piece 21 fixed to the ceiling member 13, respectively. At least two binding holes 23, 23 ', and 23 "are provided in the multi-stage coupler 22, 22' in a line up and down direction.

The multi-stage coupling spheres 22 and 22 'may be provided separately in some cases, and may be fixed to the ceiling member 13 of the diffusion hole 12, respectively.

In addition, the multi-stage coupling holes (22, 22 ') is provided with a concave guide groove 222 in the middle of the pair of wheel wheels 221, the binding holes (23, 23', 23 ") in the longitudinal direction at equal intervals And a support part 223 and a bent part 224 to the outside of the pair of wheel wheels 221.

In addition, the pair of protrusion wheels 221 is supported by a resilient member 44 fitted to any one of the binding piece (41 '41) of the pair of binding pieces (41, 41 ') detachment means described later 40, 40 'is configured to be pressurized.

In the present invention, there are binding pieces (41, 41 ') which are assembled to each of the binding means (20, 20') on both sides of the upper core portion (31) of the diffusion core (30) embedded in the diffusion hole (12). A pair of detachable means 40, 40 'is provided.

The detachable means 40 and 40 'are fixed to the upper core portion 31 of the diffusion core 30, and only the intermediate piece 42 is fixed, and both side portions 43 and 43' having the binding pieces 41 and 41 'are provided. Spaced apart from the upper core portion 31 is formed to have an air flow space portion 50 toward the lower side portions 43, 43 '.

In addition, the heating and cooling air is passed toward the upper portion of the middle piece portion 42 so that the height of the middle piece portion 42 fixed to the upper surface portion 31 is lower than the heights of both side pieces 43 and 43 '. It is made so that the air resistance can be reduced.

1 and 4, when the diffusion core 30 is coupled, the present invention first selects one binding means 20 ′ from among a pair of binding means 20 and 20 ′, and then a plurality of binding holes. (23, 23 ', 23 ") of the one binding hole 23 to be coupled to select the binding piece where the elastic member 44 in the detachable means (40, 40') in the binding hole 23 ( 41 ').

Next, when the diffusion core 30 is pushed toward the direction in which the elastic member 44 is located, the elastic member 44 is compressed and moved in the lateral direction. The binding piece 41 on the opposite side is in a state capable of being fitted into the concave guide groove 222 of the multi-stage coupling port 22 in the binding means 20.

Accordingly, the binding piece 41 is inserted into the recess guide groove 222 while the binding piece 41 is inserted into the selected binding hole 23 while maintaining the state in which the diffusion core 30 is pushed toward the direction of the elastic member 44. Make sure it fits in.

Next, when the force pushing the diffusion core 30 toward the direction of the elastic member 44 is removed, the detaching means 40, 40 ′ are oriented toward the binding means 20 by the elasticity of the compressed elastic member 44. The binding piece 41 is fitted into the binding hole 23 by being moved to be coupled.

Then, when the diffusion core 30 is separated, when the diffusion core 30 is pushed in the direction in which the elastic member 44 is located again, the binding piece 41 comes out of the binding hole 23, and is released from this state. The binding piece 41 is pulled out of the concave guide groove 222 of the multi-stage coupling hole 22, 22 'and then the other binding piece 41' is removed from the binding hole 23. 30) will be separated.

Therefore, in the present invention, since the detachable means 40, 40 'is always being pressed toward the binding means 20 by the elasticity of the elastic member 44, the detachable means 40, 40' is the blowing force of the wind. Even if it is applied, no shaking occurs, and thus no noise is generated.

In particular, the present invention employs a conical coil spring of the resilient member 44, so that the small diameter portion is supported by the pair of wheel parts 221 and positioned in the opposite direction, and the detachable means 40, 40 'is disposed. Pressurizes the desorption means (40, 40 ') in the direction that the desorption means (40, 40') is pushed in the opposite direction of the elastic member 44 receives intensive elasticity, even if a strong blowing force of the wind acts desorption means (40,40 ') ) Does not move at all, so no shaking occurs and no noise is generated.

In the present invention, the binding means (20, 20 ') and the detachment means (40, 40') are each made of an L-shape so that the fixing pieces (21, 45) in the lower portion is fixed by rivet joints or spot welds, respectively. have.

Therefore, in the present invention, the binding holes 23, 23 ', 23 "and the binding pieces 41, 41' of the detaching means 40, 40 'provided in the pair of fastening means 20, 20' are respectively rectangular. When the binding pieces 41 and 41 'are fitted into any one of the binding holes 23, the binding pieces 41 and 41' are erected in the direction in which the wind is blown, and thus receive less wind blowing force. Noise generation is prevented in advance.

To help the understanding of the present invention, for example, when the binding holes 23, 23 ', 23 "and the binding piece 41, 41' are made of circular shafts, a lot of wind blowing force is obtained in the presence of a gap such as a manufacturing tolerance. Because of the shaking may be generated noise, but the present invention is a rectangular shape is set up in the direction that the wind is blown smoothly to receive less wind blowing power is no noise is generated.

In the present invention, the multi-stage coupling holes (22, 22 ') is provided with a concave guide groove 222 in the middle of the pair of wheel wheels 221, the binding holes (23, 23', 23 ") at equal intervals in the longitudinal direction The support portion 223 and the bent portion 224 are provided to the outside of the pair of wheel wheels 221.

The pair of wheel wheels 221 and the concave guide groove 222 may be configured in the shape of a curve as shown in FIG. 3, or may be configured in a straight line as in FIG. 4, but preferably, FIG. It is preferable to have a curved shape as shown in 3.

That is, when the concave guide groove 222 is curved when the binding pieces 41 and 41 'are guided and moved along the concave guide groove 222, the binding pieces 41 and 41' are guided and moved. This is because the pieces 41, 41 'come into contact with the curved surface and slide naturally, and are fitted into the binding holes 23, 23', 23 ".

Therefore, when the binding piece (41, 41 ') to be inserted into any one of the binding hole 23, while being fitted in the concave guide groove 222 in the middle of the pair of wheel wheels 221 so that it can be easily inserted do.

In addition, since the pair of protrusions 221 for forming the concave guide groove 222 is in a protruding state, not only the concave guide groove 222 can be easily found and fitted, but also the pair of protrusions 221 are provided. In addition, since the bent portion 224 also performs the reinforcement role, the multi-stage coupler 22, 22 'is firmly supported without being bent, even though it is adopted as a relatively thin steel plate, thereby The weight can be reduced.

On the other hand, in the present invention, as shown in FIG. 1, the diffusion core 30 is a diffusion hole 12 in a state where the binding pieces 41 and 41 'are fitted into the binding holes 23 on the upper side of the multi-stage coupling holes 22 and 22'. Because it is located on the upper side of the), the heating and cooling air is in a state where it is diffused in the vertical direction.

In this state, the diffusion core 30 is separated, and as shown in FIG. 5, the binding pieces 41 and 41 'are fitted into the binding holes 23' in the lower side of the multi-stage coupling holes 22 and 22 '. If assembled so that the diffusion core 30 is located at the lower side of the diffusion hole 12, the air-conditioning air is in a state of being diffused in the horizontal direction.

Therefore, the present invention does not receive any restriction when passing through the air inlet hole 11 in the process of supplying the cooling and heating air to the room as described above, so that the blowing force is not weakened, and thus the strong blowing force is the diffusion core 30. ) Acts as a diffusion effect of the heating and cooling air is good.

In the past, the height adjustment was made in the air inlet hole 11 to help the understanding of the present invention, when the cooling and heating air passed through the air inlet hole 11 by the components, the blowing force was greatly weakened and thereby The weak blowing force acts on the diffusion core 30, so that the diffusion action of the cooling and heating air is not made good, but the present invention according to the height adjustment is made in the diffusion hole 12 in the air inlet hole 11 Since there is nothing to sanction the air, the blowing force is not weakened, so that the strong blowing force is applied to the diffusion core 30, so that the diffusion action of the cooling and heating air is good, thereby being supplied to the room The airflow of the heating and cooling air will increase.

That is, in the past, indoor air-conditioning efficiency was lowered because the amount of air per hour was reduced by decreasing the blowing force, but according to the present invention, the amount of air per hour is increased because the air blowing power is improved, and thus the indoor air-conditioning efficiency is greatly improved.

On the other hand, the air-conditioning air blown to the air inlet hole 11 is first blown toward the core upper surface portion 31 is in a state of being diffused in all directions.

At this time, it is diffused in the direction of the arrow shown in Figure 4, wherein the air-conditioning air diffused to the removable means (40, 40 ') is fixed to the core upper surface portion 31 than the height of the two side portions (43, 43') Since the height of the one-piece 42 has a relatively low height, the air heating and cooling air toward the upper portion of the intermediate piece 42 is less affected by the minimum air resistance, thereby smoothly flowing the cooling and heating air.

In the air-conditioning air diffused toward both side portions 43 and 43 'of the detachable means 40 and 40', both side portions 43 and 43 'and the core upper surface portion 31 are separated from each other. ') Since the air flow space portion 50 is provided toward the lower side, since both side portions 43 and 43' serve as guide members for inducing one air flow, the two side portions 43 and 43 'are diffused toward both side portions 43 and 43'. Cooling and heating air is led to the air flow space 50 has an air flow to the exit state.

Therefore, the cooling and cooling air flow is good, so that not only the blowing force is lowered, but the blowing wind is good, so the parts are less wind-resistant, so noise is prevented.

 And the present invention is not only to adjust the height of the diffusion core 30 is easy and easy, but also to adjust the height of the diffusion core 30 by turning the diffusion core 30 is not easy to adjust the height just by detaching the diffusion core 30 in the vertical direction. 6 shows the embodiment as it can be applied to all types of diffuser without regard to the shape of the diffuser.

Referring to FIG. 6A, in the present invention, the rectangular diffusion core 30 also includes the binding means 20 and 20 'and the removable means 40 in the rectangular main body 10 having the rectangular diffusion holes 12. 40 ') can be detachably implemented.

In addition, the present invention as shown in Figure 6b has a circular diffusion core 30 in the rectangular body 10 having a circular diffusion hole 12, the binding means (20, 20 ') and the removable means 40, 40 ') may be detachably implemented.

In addition, the present invention as shown in Figure 6c has a circular diffusion core 30 of the circular shape in the main body 10 having a circular diffusion hole 12 of the binding means (20, 20 ') and the removable means 40 , 40 ') may be detachably implemented.

7 and 8, the binding means 20, 20 ′ and the detaching means 40 provided in the diffusion hole 12 also in the diffuser having the damper D and the damper adjusting hole G. , 40 'may be implemented so that the diffusion core 30 is detachable from the main body 10.

 Of course, since the damper control mechanism (G) is already known as assembling and detachable, detailed drawings and descriptions will be omitted, and after removing the damper control mechanism (G), the diffusion core 30 is removed from the main body 10. It is detachable.

Therefore, the present invention is not only to improve the diffusion performance of the cooling and heating air, but also to improve the flow of cooling and heating air because the flow of the cooling and heating air is made good while controlling the height of the diffusion core 30, the blowing force is lowered It is not caused to increase the amount of air-conditioning and air supplied to the room, because the air flow is good blown because the parts are less wind resistance can prevent noise generation in advance.

By minimizing the wind resistance of the parts by improving the airflow of air conditioning and heating air, it is possible to adopt parts of relatively thin thickness, which not only reduces manufacturing costs but also makes the diffuser significantly lighter than before. Will be.

The present invention is not necessarily limited to those shown and described by way of example, and may be modified in various forms by those skilled in the art to which the present invention pertains, and thus the protection is broadly provided without departing from the scope of the claims.
