Description

support mechanism

Technical field

The invention relates to the technical field of water heaters, and in particular to a support mechanism.

Background technique

The heat pump water heater can absorb the low-temperature heat in the air, vaporize it through the fluorine medium, then compress it through the compressor and pressurize it to heat up, and then convert it through the heat exchanger to heat the water. The compressed high-temperature heat energy is used to heat the water temperature, which is highly efficient. Energy-saving features: the same amount of hot water produced is 4-6 times that of ordinary electric water heaters. Its annual average thermal efficiency ratio is 4 times that of electric heating, and its energy efficiency is high.

The main working part of the heat pump water heater is the compressor. The compressor will vibrate when working, so there is a lot of noise. Placing the water tank of the heat pump water heater on the upper side can effectively suppress the vibration of the compressor and reduce the noise. However, placing the water tank of the heat pump water heater on the upper side can effectively suppress the vibration of the compressor and reduce the noise. Placing the water tank on the upper side will cause the problem of unstable center of gravity. The existing technology cannot solve this problem, which has always troubled those skilled in the field.
