Abstract

PURPOSE:To contrive to improve the combustion performance and thermal efficiency of the titled unit by a structure wherein a baffle plate equipped with flexible plates is provided within the interior of an exhaust pipe connecting a heat exchanger and an exhaust fan in order for the baffle plate to block the upper part of a heat exchanger, which is put out of use only when either hot water supplying operation or heating operation is put into action independently. CONSTITUTION:When the titled unit is used either for hot water supply only or for heating only, high temperature exhaust gas is produced on the in-use side, because combustion proceeds, and is lead to an exhaust fan. At this time, flexible plates 9 provided on a baffle plate 8 band themselves, because the one end of each plate 9 is fixed, by being heated with high temperature exhaust gas, resulting in opening the slit parts provided on the baffle plate so as to form the passages of the exhaust gas. On the contrary, because the temperature at the out-of-use side (non-combustion side) is low, flexible plates do not bend themselves, resulting in blocking the slit parts 10 provided on the baffle plate. Thus, no air enters from the out-of-use side, resulting in improving the combustion performance and accordingly also enhancing the thermal efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the configuration of an exhaust stack that connects a heat exchanger and an exhaust fan of a hot water heater using gas, oil, or the like as fuel.

t' of the conventional example: ii formation and -during 1. llL' is conventionally used to install a heat exchanger for this supply and for Ishiba.
In the case of a hot water supply machine, the configuration VC is equipped with a large number of heat exchangers for the hot water supply side and the hot water supply side to improve combustion performance and thermal efficiency. The exhaust gas that has passed through the heat exchanger is discharged outside the machine by a 1N exhaust fan, so hot water supply,
The drawback is that when a warm person burns alone, air sometimes enters from one side (non-combustion side), affecting combustion performance and thermal efficiency.

For example, in the conventional example shown in FIG. The combustion gas that passed through the heat exchangers for heating and heating was collected in the L part of the engine and connected to a motor 5.The exhaust pipe 7 was used exclusively for the air fan 6. If this conventional configuration is used for combustion, for example, when the hot water supply side is used and the warm waste side is not used, there will be no combustion (air enters from the heating II-III heat exchanger 4 side and the hot water supply side burns 1). ．It has a negative effect on performance and efficiency.
Similar drawbacks existed when using 1z/till k, which was a problem.

OBJECTS OF THE INVENTION The present invention improves the advantages of the conventional examples. (Elimination-1-
The purpose of this project is to improve the combustion performance and thermal efficiency of hot water heaters.

In order to achieve distribution efficiency in the configuration of the invention, the hot water heater of the present invention is provided with a heat exchanger for hot water supply, 1 heat exchanger for heating S, and 1
1.Inside the Pl-air 11) which connects the air fan, install an extensible self-made board base-(+iii) 11 (4+ii+
It is configured to close off the upper part of the heat exchanger on the side that is not used when the heater is used alone, preventing the impact on combustion performance and thermal efficiency. This has the effect of

DESCRIPTION OF EMBODIMENTS OF THE INVENTION From now on, one embodiment of the present invention will be explained based on the drawings.

FIGS. 2M to 4 show a heating/cooling unit 1 according to an embodiment of the present invention.

In Fig. 2, the supply heat exchanger 3 and the heating heat exchanger 4 installed in the combustion burner 2, which is not provided inside the main body 1 in Fig. 2, are connected to the air fan 6. There are 8 resistance plates inside the 7-port exhaust pipe. In Fig. 3-4, the resistance plate 9 is provided with a retractable plate 9.

The operation of the configuration described below will be explained.

The high ff1i'+ combustion gas combusted by the combustion burner 2 at the bottom of the main body 1 in the hot water heater constructed as described above is transferred to the heating heat exchanger 3. Heat is exchanged in the heat exchanger 4 for heating, and the gas becomes exhaust gas and is discharged outside the main unit from the exhaust fan 6. However, when hot water supply or heating is used alone, the side being used is hot due to combustion. Exhaust gas is generated and guided to the exhaust fan 6. At this time, a retractable plate 9 provided on the resistance plate 8
Since one end of the resistor plate is fixed, it is heated by high-temperature exhaust gas and warped, and a slit formed in the resistor plate is opened to form a passage for exhaust gas. On the other hand, the unused side (non-combustion side) is low 1
? Because of this, the stretchable plate does not warp and closes the slit portion 10 provided in the resistance plate.

Due to this, there is no more air intrusion than when not in use.
Combustion performance is improved and thermal efficiency is also high.

In this way, according to this embodiment, even if a 2-can, 2-water type hot water heater and heater with combustion burners and heat exchangers are used for hot water supply and space heating, respectively, and combustion is performed independently, the air from the side that is not being used is The 11111 rat that is used without intrusion:
An ideal combustion flame of 4"l and primary, -° secondary, trowel type IIv, and 7L is formed in the upper burner.
Combustion performance improves. , subordinate -, -(245 Thermal efficiency of the heat exchanger is lj'7j <x'
, the design becomes more efficient.

Historically, as mentioned above, the combustion flame and the heat exchanger are ideally 15.24 (the exchanger σ month 61.1 durability is also 1-1).

Effects of the Invention (1-ri5i', clarification rζ)) The easy heating device of the present invention has a configuration in which the exhaust outlet can be opened or closed by a telescopic plate provided in the exhaust pipe. , a product with good combustion performance, high thermal efficiency, and excellent durability can be obtained.
