Embodiment 1

[0031] First, based on figure 1 , the overall structure of the heating and hot water supply device 1 of the present invention will be described.

[0032] The heating and hot water supply device 1 performs a heating operation by circulating a heating medium between the heating and hot water supply device 1 and a heating terminal (not shown), and performs a hot water supply operation in which The clean water heated by the heat exchange of the heating medium heated by the heat exchange with the combustion gas generated by the combustion unit 2 is adjusted to the hot water supply set temperature to supply hot water.

[0033] The heating and hot water supply device 1 includes a combustion unit 2 that is a combustion element that mixes and burns fuel gas and air, a heat exchanger 10 that heats a heating medium by exchanging heat with combustion gas generated by combustion, The circulation passage 4 connecting the heat exchanger 10 and the heating terminal, the circulation pump 11 ...

Embodiment 2

[0065] Next, based on Figure 4 , the heating and hot water supply device 1A of the second embodiment will be described.

[0066] The heating and hot water supply device 1A can be adjusted by using the bypass flow regulating valve 23A provided on the second bypass passage 22A instead of the second distribution valve 23, which is the flow regulating element of the second bypass passage 22 in the first embodiment. formed by bypass flow. The second bypass passage 22A is branched from between the flow rate adjustment valve 24A provided on the hot water supply passage 21A and the hot water supply volume sensor 25A.

[0067] Next, the operation and effect of the heating and hot water supply device 1A will be described.

[0068]In the hot water supply operation, the control unit 7A adjusts the hot water supply water to the hot water supply set temperature based on the hot water output temperature detected by the hot water output temperature sensor 27A or the temperature detected by...

Abstract

The invention provides a heating and hot water supplying device that is provided with a heat exchanger for hot water supply that can ensure an installation space for a distributing valve, a bypass channel, and a bypass flow regulating means without making the heating and hot water supplying device larger and that allows simultaneous heating and hot water supply operations and can appropriately control the temperature of the hot water supply. A heating and hot water supplying device comprises a combustion means, a heat exchanger, a circulation channel that connects the heat exchanger and a heating terminal, a circulation pump provided in the circulation channel, a first bypass channel that branches from the circulation channel and bypasses the heating terminal, a heat exchanger for hot water supply that is provided in the first bypass channel, and a hot water supply channel for supplying tap water to the heat exchanger for hot water supply and for supplying hot water heated by the heatexchanger for hot water supply. A distributing means is provided in a branching portion of the first bypass channel, and the distribution ratio can be adjusted so as to enable each of a heating operation, a hot water supply operation, and a simultaneous heating and hot water supply operation. A second bypass channel that bypasses the heat exchanger for hot water supply is provided in the hot watersupply channel, and a flow regulating means that can regulate the bypass flow rate of same is provided. The heat exchanger for hot water supply is configured to be a plate-type heat exchanger, and apair of first bypass channel couplers and a pair of hot water supply channel couplers are disposed in one side face thereof.

Description

technical field [0001] The present invention relates to a heating and hot water supply device that uses combustion heat to heat a heating medium for heating, and heats clean water through heat exchange with the heating medium to supply hot water. A heating and hot water supply device capable of simultaneously performing a heating operation and a hot water supply operation. Background technique [0002] Conventionally, heating and hot water supply devices that switch between a heating operation and a hot water supply operation have been widely used. This heating and hot water supply device burns the fuel to heat the heating medium with the heat exchanger during the hot water supply operation, and the heating medium is placed between the heat exchanger and the hot water supply heat exchanger. cycle. As the heat exchanger, a fin and tube type heat exchanger that recovers sensible heat of combustion gas is used, and there is also a heat exchanger that can heat a heating medium...
