An energy-saving thermal storage water heater

Abstract

The invention discloses an energy-saving heat storage water heater, which comprises a water heater cavity, a water tank water outlet and a water tank water inlet respectively arranged on the upper and lower sides of the water heater cavity, a thermal insulation and isolation cavity is arranged in the water heater cavity, and the thermal insulation and isolation cavity is provided with A diaphragm that separates it into two parts, the heating water chamber and the gas-filled chamber. The heating water chamber is provided with an electric heater and a first temperature probe. The upper and lower parts of the heating water chamber are respectively provided with an inner cavity water outlet and an inner cavity water inlet. The inner cavity water inlet and the inner cavity water outlet are opened and closed by the first cock and the second cock respectively, a second temperature probe is arranged in the water heater cavity, and a thermostat is arranged on the outer wall of the water heater cavity, and the thermostat is respectively controlled by The wire is connected with the first temperature probe and the second temperature probe, and the temperature controller is respectively connected with the power supply and the electric heater through the power wire. The energy-saving heat storage water heater of the present invention can reduce the standby energy consumption of the water heater so as to realize energy saving.

Description

technical field [0001] The invention relates to an energy-saving heat storage water heater and the field of energy-saving of hot water equipment. Background technique [0002] In the field of energy saving of hot water equipment, the standby energy consumption of heat storage water heaters cannot be ignored. The reasons are that firstly, the number of heat storage water heaters or equipment with similar functions is extremely large, and second, that the standby time of heat storage water heaters is generally much longer than the use time. The third is that although the shell of the heat storage water heater uses a certain thickness of polyurethane foam or similar insulation materials, heat preservation does not mean heat insulation, because the temperature difference between hot water and the outside world will continue to dissipate heat outward. According to the statistical law, about 90% of the time in a day is in the standby state. If the shutdown method is used to save e...

[0002] In the field of energy saving of hot water equipment, the standby energy consumption of heat storage water heaters cannot be ignored. The reasons are that firstly, the number of heat storage water heaters or equipment with similar functions is extremely large, and second, that the standby time of heat storage water heaters is generally much longer than the use time. The third is that although the shell of the heat storage water heater adopts a certain thickness of polyurethane foam or similar insulation materials, the heat preservation does not mean the heat insulation, because the existence of the temperature difference between the hot water and the outside world will continue to dissipate heat outward

According to the statistical law, about 90% of the time in a day is in the standby state. If the shutdown method is used to save energy, because most of the water heaters are electric heating, the power of the configured electric heater cannot adopt the high-power configuration of the instant water heater, so The heating time is longer, which affects the user experience
