Thermostatic instant heating water storage type electric heater

Abstract

The invention discloses a constant temperature instant heating water storage type electric water heater; the invention is characterized in that a water storage tank(1) is provided inside with a constant temperature heater(5) and a heat radiation collector(10), the heat radiation collector(10) provided inside with a muff heater(4) has a water outlet connected with a mixing temperature limiter(6) of which an water outlet is communicated with the constant temperature heater(5) by an admitting pipe(15); the constant temperature heater(5) is provided with a temperature sensor(9), the muff heater(4) is provided with a water flow sensor(8); an electric thermostatic control device(7) is connected with the temperature sensor(9) and the water flow sensor(8). The mixing temperature limiter(6) can apply the structure or the similar structure disclosed in the Chinese patent of invention (Z1200420047315.3). Because the invention adopts the technical proposal, thereby the guaranteeing that when the present constant temperature supply is started and the present water storage tank is heated, the hot water can continuously be generated, which effectively resolves the defect existing in prior art; because the mixing temperature limiter is applied in the invention, the temperature of the water entering in the constant temperature heater can be accurately adjusted, thereby causing the following heating and the temperature control convenient, improving the heating efficiency and avoiding the loss of the energy resources.

Description

technical field [0001] The invention relates to a water heater, in particular to a constant temperature instant heat storage electric water heater. Background technique [0002] It has been almost a century since the invention of the electric water heater. Since the existing water heaters on the market, including the ones mentioned above, all use manual mixing valves or mechanical thermostats to control the water temperature, it is believed to be extremely inconvenient for users, especially common ones. Thermostat, when the temperature difference of the water tank is lower than required, the constant temperature control will immediately fail, which is no different from operating the manual mixing valve, so it is not very popular. Contents of the invention [0003] The present invention aims at the problems of the above-mentioned commercially available water heaters. The purpose of this invention is to prevent the failure of constant temperature control based on a brand-new...
