As described above, the combustion chamber 102 is composed of a horizontal communication 104a-1, a front communication 104a-2, a vertical rear communication 104a-3, and a lower front communication 104a-4. Thus, the heat generated from the radiator 104, which receives the flame ejected from the gas burner 101 installed in the combustion chamber 102, is more effective in horizontal communication 104a-1 and forward communication 104a-2. And, it is transmitted to the vertical rear communication 104a-3, the lower front communication 104a-4, and the horizontal communication 104a-1, the front communication 104a-2, and the vertical rear communication 104a-3, In addition, the rinsing water delivered to the plurality of heating pipes 201 installed in the rinsing water heating chamber 204 by effectively transferring heat into the rinsing water heating chamber 204 connected to the lower front communication 104a-4. The heating is to produce rinsing water of hot water.

That is, the heat generated from the radiator 104 of the combustion chamber 102 is supplied to the drying chamber E through the blower 103 and the hot air knife 106 and at the same time, the horizontal communication installed in the combustion chamber 102. (104a-1), front communication (104a-2), vertical rear communication (104a-3), and lower front communication (104a-4) by applying heat to horizontal communication (104a-1) and forward communication ( 104a-2, the rinsing water supplied to the plurality of heating pipes 201 in the rinsing water heating chamber 204 connected to the vertical rear communication 104a-3 and the lower front communication 104a-4, This is to save energy more effectively by generating rinsing water of hot water to more efficiently use the heat in the combustion chamber 102.

In addition, the hot air knife 106 formed in the lower portion of the heat dissipation chamber 105 has an upper portion formed with an extension portion 106a, and is formed of a supply pipe 106b formed perpendicularly to the lower portion of the expansion portion 106a. do.

In addition, the expansion portion 106a is preferably formed of a light beam.

As described above, the hot air knife 105 includes the expansion part 106a and the supply pipe 106b so that the heat generated in the radiator 104 of the combustion chamber 102 is transferred to the blower 103. It is to force the effective supply into the drying chamber (E) through the expansion (106a) and the supply pipe (106b).

On the other hand, the blower 103 is installed on the other side of the radiator 104, the blower 103 is forced to blow the hot air heated in the radiator 104 to the drying chamber (E) through the hot air knife (106). Play a role of

In addition, the heat dissipation chamber 105 and the other side is installed and connected to one side of the bore 103, the expansion induction part 103a to more stably supply the wind generated in the bore into the heat dissipation chamber 105 It is provided and configured.

That is, to effectively supply the generated heat of the combustion chamber 102 into the drying chamber E more effectively through the expansion induction part 103a.

The heat exchanger 200 is installed on one side of the combustion chamber 102 to be heated by the gas burner 101.

The heat exchanger 200 is composed of a rinse water heating chamber 204.

A plurality of heating pipes 201 are horizontally installed in the rinse water heating chamber 204 so as to be heated by the waste heat generated by the radiator 105.

The heating pipes 201 are connected to each other so that the inlets (not shown) formed in the heating pipes 201 are connected to each other to communicate with each other.

In addition, a hot water outlet 202 is formed in the heating pipe 201 installed on one side of the plurality of heating pipes 201 installed in the rinsing water heating chamber 204 of the heat exchanger 200, The cold water inlet 203 is installed in the heating pipe 201 installed.

Cold water is supplied to one lower side of the rinsing water heating chamber 204, and the cold water is heated to receive the heat supplied to the rinsing water heating chamber 204, and hot water is discharged to one upper portion.

The hot water is rinsing water, and the rinsing water converted into hot water is sent to the rinsing chamber C for recycling.

In addition, an exhaust port 204a is provided at an upper side of the rinse water heating chamber 204 to exhaust the heat supplied to the rinse water heating chamber 204.

The heat exchanger 200 as described above is installed on one side of the radiator 104, the heat exchanger 200 is provided with a cold water inlet 203 and a hot water outlet 202 waste heat exhausted from the radiator 104 Serves to heat the rinsing water. At this time, the hot water outlet 202 is connected to the rinse arm 14 in the rinsing chamber (C). Therefore, according to the present invention, since the rinsing water can be heated by recycling the heat energy exhausted from the radiator 104, the total amount of electricity consumed can be greatly reduced.

Gas-type hot air drying apparatus for a dish washer according to the present invention configured as described above is also installed in the upper part of the drying chamber (E) to supply hot air to the drying chamber (E) to dry the dish (3) with hot air as in the prior art.
