The present invention relates to a louver assembly.

Conventional hot air heaters and the like provide a louver at a hot air outlet to regulate a blowout direction. However, the louver is integrated by attaching and fixing a plurality of louvers to a connecting member arranged on both sides.

In particular, the gas bath is mainly provided indoors, the exhaust port formed in the upper part of the combustion chamber is provided with a metal exhaust hood made of a louver assembly.

This exhaust hut is capable of smoothly discharging the combustion gas generated in the combustion chamber, and prevents the natural rise of the heat lamp to prevent the temperature rise of the hanging cupboard placed above the gas cooker. In order to change the discharge direction of the heat and heat, the exhaust hood is provided with a plurality of louvers with a predetermined angle with respect to the upper portion.

These louvers are arranged at non-transmissive intervals of heat exchangers, etc. from the top of the gas cooker, so as to satisfy the standard, so as to be provided with metal plates disposed on both sides of each louver. It is inserted into a groove formed in the connecting member and fixed.

Thus, since the assembly of a louver is conventionally integrated with a plurality of louvers by a connecting member, a large number of parts points and assembly labor are required, resulting in an increase in production cost and assembly of each part. To this end, there is a problem that the quality deviation of the product is large because the allowable range of the dimensional accuracy must be increased.

It is an object of the present invention to provide a louver assembly which is inexpensive and has a low quality deviation of the product.

The present invention is a louver assembly consisting of a plurality of louvers having a long plate shape and arranged in a generally short side direction, and connecting portions disposed at both sides of the plurality of louvers to connect the plurality of louvers, wherein the connecting portions are provided. Technical means that the plurality of louvers are formed integrally with the plurality of louvers having a bent portion providing a predetermined angle with respect to the plurality of louvers while forming a ventilation path between the plurality of louvers.

In the present invention, the plurality of louvers are formed integrally with the connecting portion, and are arranged in a short side direction by giving a predetermined angle to each louver so that a ventilation passage is formed between the louvers at the time of bending the connecting portion.

As such, each louver and the connecting portion may be integrally formed to form the louver assembly only by bending the connecting portion.

In the present invention, since the assembly of the louver and the connecting portion is not necessary, the processing work is reduced. Therefore, there is an effect that the production cost can be down.

In addition, the dimension of the assembly is not required, and the precision of the dimension is improved because the angle of the louver and the spacing of the ventilation passages are determined and arranged by the bending processing of the joint.

Next, the present invention will be described based on Examples.

FIG. 2 is a view showing a wall-mounted gas stove 1 that is capable of tapping by soft touch operation.

A gas burner (not shown) is disposed inside the main body cover 2, and a water pipe type heat exchanger (heated by a gas burner) is heated on the upper portion of the gas burner as shown in FIG. 3) is excreted.

The heat exchanger 3 is provided with a plurality of fins 3a, and the heat exchanger 3 is enclosed together with the fins 3a by a cylindrical combustion casing 4 forming a combustion chamber, and the combustion casing 4 An exhaust port 4a is formed at the upper end, and the exhaust port 4a is covered by the exhaust hood 10.

In the exhaust hood 10, a plurality of louvers 11 having a generally thin and rough shape are arranged in a substantially short side direction, and the combustion gas of the gas burner or the heat after digestion are smoothly disposed between the louvers 11. As the exhaust passage 12 is formed to discharge to the outside of the gas stove 1, the plurality of louvers 11 are formed integrally of the connecting portion 13 for connecting the louvers (11) It is fixed to the heat exchanger 3 at the part of the connection part 13 via the fixing leg member which is not shown in the heat exchanger 3 which is not shown.

As shown in FIG. 3, the exhaust hood 10 includes a plurality of louver separation grooves 14 each having a smaller number than the number of louvers 11 corresponding to the number of louvers 11 on one metal plate. , The bending groove 15 for bending the connecting portion 13 to give a predetermined angle with respect to each louver 11 is formed as a continuous groove so as to show a substantially H-shape, and each louver The ribs 16 for reinforcement are formed at the connecting portions between the connecting portion 13 and the connecting portion 13, respectively, and the upper bending portion 13a indicated by the broken line in FIG. There is a lower bending part 13b indicated by a dashed line.

In addition, the bending angle in each bending process is as shown in FIG. 1, and each louver 11 is arrange | positioned giving a predetermined angle, and the upper end part of each louver 11 adjoins the louver ( 11) is located on the vertical surface of the lower end.

As a result, each louver 11 forms a continuous projection surface by the adjacent louver 11, and the exhaust hood 10 covers the internal heat exchanger 3 as shown in FIG. When viewed from the top of the gas scrubber 1, the heat exchanger 3 and the like do not appear.

In the gas water heater (1), a pipe cover (5) is disposed below the main body cover (2), and a water supply switch (6) for instructing the start and stop of the drainage operation on the surface of the pipe cover (5). And a temperature control slide lever 7 for adjusting hot water temperature by adjusting the water supply amount, and further, a hot water switching switch 8 for selecting whether or not to heat the gas burner at the time of water supply. The water supply switch 6 has a surface covered with a sheet and has no irregularities like a so-called sheet switch, and has an electrical contact therein.

Therefore, the main body cover 2 can be easily wiped without any obstacle, and when removing the main body cover 2 at the time of inspection of burner, etc., it is not necessary to remove the handle or lever of each switch. It can be done simply.

A flexible processing tapping pipe 9 connected to the heat exchanger 3 is disposed below the piping cover 5, and a shower head 9a having a water flow switching mechanism is provided at the end of the tapping pipe 9. It is.

In the gas water purifier 1 of the present embodiment having the above configuration, when a water supply switch 6 is operated, a water supply valve (not shown) is opened to start water supply. If water is selected by the water supply switching switch 8, As gas flows, the fuel gas is supplied to the governor and the ignition operation is performed to ignite the gas burner. The water is heated by the heat exchanger 3 and the hot water flows out of the shower head 9a.

During combustion of the gas burner, combustion gas is discharged through the exhaust passage 12 of the exhaust hood 10. At this time, the combustion gas is discharged by the louver (11) is determined.

When the water supply switch 6 is operated during water supply, the water supply is stopped, and when the gas burner is in combustion, fuel supply is stopped and extinguished at the same time.

After extinguishing, the heat caused by the excess heat of the gas burner or the heat exchanger 3 rises due to natural convection, but the discharge direction is determined by the louver 1l of the exhaust hood 10.

Therefore, heat does not directly reach the hanging cupboard etc. which are installed in the upper part of the gas cooker 1.

As described above, according to the present invention, since the louver and the connecting portion are integrally formed in the exhaust hood, the production cost can be reduced and the dimensional accuracy is improved.

In this case, securing of an exhaust passage for the exhaust lamp, which is a necessary condition for the exhaust hood, and internal heat exchange lamps in the projection from the upper side do not appear.

In the above embodiment, the lower end of each louver and the upper end of the adjacent louver coincide in the vertical direction. However, when the projection is performed, the overlapping part may occur. Moreover, when using the louver assembly of this invention for a warm air heater, you may set so that an inside may not be seen without overlapping at all.
