Problems solved by technology

The heat pump evaporator with air as the heat source has a large volume, and the water supply temperature of the condenser is greatly affected by the ambient temperature. In winter, when the ambient temperature is lower than -5°C, the heating efficiency is extremely low, and an auxiliary electric heat source needs to be added
In the prior art, there is a heat pump water heater technology using waste water from bathing as a heat source, such as the Chinese patents applied by Hu Guangnan (application number: 99121448.x) and Li Fan (application number: 00239867). When the heat pump works, there is The water supply temperature is not stable and cannot reach the bathing temperature

Embodiment Construction

[0010] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] The system structure of the present invention is attached as figure 1 As shown, it includes the bathing water system, the waste water discharge system and the refrigerant circulation system of the heat pump unit. The connection relationship of the refrigerant circulation system of the heat pump device is as follows: the outlet of the compressor 1 is connected to the refrigerant inlet of the sleeve condenser 2 through a pipeline, and the refrigerant outlet of the sleeve condenser 2 is controlled with the condensing pressure through a pipeline. The inlet of the valve 4 is connected, the outlet of the condensing pressure control valve 4 is connected with the inlet of the liquid reservoir 5 through the pipeline, the outlet of the liquid reservoir 5 is connected with the inlet of the throttling device 6 through the pipeline, and the outlet of ...

Abstract

An energy-saving shower bath appliance with instantaneously heating heat pump is composed of compressor, condenser, condensing pressure control valve, liquid accumulator, throttle unit, coiled evaporating tube, air-liquid separator, pressure difference control valve, water collector, water mixer water level control valve, etc. Said pressure difference control valve and condensing pressure control valve are used to control the temp and heat of refrigerant in condenser for heating cold water. The cold and hot water valves are used to control the temp of bath water. The water level control valve and sensor and used to control the discharge of used water.

Description

Technical field: [0001] The invention relates to a shower, in particular to an energy-saving instant heat pump shower, which belongs to the technical field of heat pump equipment. Background technique: [0002] With the improvement of people's living standards, the demand for sanitary hot water is becoming more and more intense, and people hope to obtain sanitary hot water conveniently throughout the year. There are mainly five ways of supplying hot water for existing showers: one is to install an electric heating water heater, which directly uses electric energy to heat water. Network connection, although it can be used immediately, but the initial installation fee is high. During use, due to the inevitable heat loss of the hot water network, the operating company will pass all the loss to the user, and the user's use cost is high; the third is to install gas-fired The water heater can be turned on immediately, but the gas-fired water heater needs to be installed in a well...
