Semiconductor heat pump energy-saving instant-hot faucet

Abstract

The invention discloses a semiconductor heat pump energy-saving instant-hot faucet. The semiconductor heat pump energy-saving instant-hot faucet comprises a thermoelectric heat pump chip layer, a heating circuit, a waste heat recovering circuit and a water temperature control device. The thermoelectric heat pump chip layer is composed of a plurality of circular thermoelectric heat pump chips, the cold end face of the thermoelectric heat pump chip layer and the hot end face of the thermoelectric heat pump chip layer are connected with the waste heat recovering circuit and the heating circuit respectively, a heat preservation and thermal insulation gasket is arranged between the waste heat recovering circuit and the heating circuit, and the water outlet temperature of the semiconductor heat pump energy-saving instant-hot faucet is adjusted through a water temperature control rotary knob. Basin drainage waste heat is recovered through the functions of a semiconductor heat pump, tap water is rapidly heated after secondary heat quantity increasing is conducted on the semiconductor heat pump, the semiconductor heat pump energy-saving instant-hot faucet has the advantages of being controllable in water outlet temperature, rapid, capable of saving energy, compact in structure and the like, and the semiconductor heat pump energy-saving instant-hot faucet can be directly installed on an existing domestic water system and has practicability and comfort.

Description

technical field [0001] The invention relates to an energy-saving instant hot water device, in particular to an energy-saving instant hot water faucet which adopts a semiconductor heat pump to recover waste heat from drainage. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people's demand for hot water is increasing. Whether it is winter or summer, the use of domestic hot water is inevitable, and various forms of electric water heaters, gas water heaters, etc. have appeared thereupon. Although existing water heaters can meet people's needs to a certain extent, all existing water heaters have their own technical defects: electric water heaters and gas water heaters have low energy efficiency coefficients and potential safety hazards of electric leakage or gas leakage; The structure of the heat pump water heater system is relatively complex, the cost is high, and the technology is still immat...

Problems solved by technology

Although existing water heaters can meet people's needs to a certain extent, all existing water heaters have their own technical defects: electric water heaters and gas water heaters have low energy efficiency coefficients and potential safety hazards of electric leakage or gas leakage; The structure of the heat pump water heater system is relatively complex, the cost is high, and the technology is still immature; the solar water heater is greatly restricted by factors such as region, climate, and number of floors

However, the limitations of general electric heating instant hot water faucets are quite obvious. For example, the heating efficiency of instant hot water faucets is limited to less than 1. The water and electricity separation device installed for the safety of electricity increases the complexity of the overall structure. For the hard water in the north In some cases, the complex structural surface of the instant hot water faucet is prone to scale, the device is difficult to disassemble, and it is inconvenient to clean the internal dirt, etc.

After retrieval, the Chinese Patent Publication No. CN202532008U, the name of the utility model is: instant hot water faucet; the hot water faucet uses a stainless steel metal electric heating film heating tube to heat cold water, and separates water and electricity by coating an insulating medium on a stainless steel plate. However, the device directly adopts electric heating, and its heating efficiency is about 0.95, and the device directly discharges the waste water after use, so that a large amount of waste heat contained in the waste water is still unused, and its energy-saving effect is very limited.
