Embodiment Construction

[0019] A first embodiment of the present invention will be described below. Fig. 1 is an explanatory diagram of a circuit of a heat pump water heater, a hot water storage type water heater applicable to the present invention. The heat pump type water heater is mainly composed of: a heat pump unit A as a heat source, which is composed of a refrigerant line for exchanging heat between refrigerant compressed in a compressor and water by a heat exchanger for heating; a tank unit B, which utilizes a cycle The pump circulates water between the hot water storage tank and the heating heat exchanger, and at the same time discharges hot water from the hot water storage tank.

[0020] The heat pump unit A includes: a high-temperature and high-pressure compressor 1 for sucking compressed refrigerant, a refrigerant-to-water heat exchanger 2 for heating refrigerant and water for heat exchange, and an electric expansion valve 3 as The evaporator 4 of the heat exchanger on the outdoor side, ...

Abstract

PROBLEM TO BE SOLVED: To provide a safe hot water supply machine not causing a user's scald by detecting failure even if a hot water supply temperature detection sensor fails. SOLUTION: This hot water supply machine has: a heat source heating stored water inside a hot water storage tank 10 or tap water to a set temperature; a hot water supply flow rate sensor 16 detecting a hot water supply amount from the hot water storage tank 10 or the heat source; the hot water supply temperature detection thermistor 15 for detecting a hot water supply temperature; and a controller controlling a heating amount of the heat source according to the hot water supply temperature detected by the thermistor 15. When the thermistor 15 successively detects a temperature not more than a prescribed temperature (55°C) for a prescribed time (10 sec) after detecting a hot water supply amount not less than a prescribed amount (2 liters per minute) by the hot water supply flow rate sensor 16, a microcomputer 25 decides that the thermistor 15 is abnormal.

Description

technical field [0001] The present invention relates to a heat pump type hot water storage water heater utilizing the condensation heat of an electric heater and a refrigerant, and an instantaneous water heater for generating warm water for hot water supply by burning gas and oil. Specifically, it relates to detection of hot water supply. The temperature of the hot water supply temperature detection sensor fault detection device. Background technique [0002] At present, this kind of water heater is a heat pump type heat source that uses the condensation heat of the electric heater and the refrigerant to heat the water in the hot water storage tank, and stores hot water at high temperature. The mixing valve for mixing hot water and low-temperature tap water provides hot water at a temperature set by the user by adjusting the mixing ratio of the high-temperature hot water and low-temperature tap water by detecting the temperature of the mixed hot water with a hot-water supply...
