Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Figure 1 to Figure 12 As shown, a closed water boiler includes a main inner tank 1, an electric heater 2, a water inlet pipe 3, an outlet pipe 4 and an auxiliary inner tank 5. The main inner tank 1 adopts a stainless steel inner tank, and the electric heater 2 is attached to the The lower surface of the main inner tank 1, the electric heater 2 heats the water entering the main inner tank 1, and the electric heater 2 includes a cooling plate 21, which is attached to the lower surface of the main inner tank 1, and the lower surface of the cooling plate 21 The surface is fixedly connected with an electric heating tube 22 and an over-temperature protector 23. When the main liner 1 lacks water and is dry-boiled, the over-temperature protector 23 cuts off the power supply of the electric heating tube 22; Pipe 22 just can not knot s...

Abstract

The invention discloses a closed type water boiler which comprises a main liner, an auxiliary liner, a water inlet pipe, a water outlet pipe and an electric heater for heating water; the water inlet pipe penetrates into the main liner and the lower end of the water inlet pipe communicates with an inner cavity of the main liner; a water inlet electromagnetic valve is arranged at the part, located outside the main liner, of the water inlet pipe; the water outlet pipe penetrates into the main liner and the lower end of the water outlet pipe communicates with the inner cavity of the main liner; a water outlet electromagnetic valve is arranged at the part, located outside the main liner, of the water outlet pipe; an inner cavity of the auxiliary liner communicates with the part, below the water inlet electromagnetic valve, of the water inlet pipe through a by-pass line; a floating part is arranged in the by-pass line; an exhaust pipe penetrates into the auxiliary liner and the lower end of the exhaust pipe communicates with the upper part of the inner cavity of the auxiliary liner; a floating part moves downwards in place and plugs the by-pass line through a first sealing part; and the floating part moves upwards in place and plugs the lower end of the exhaust pipe through a second sealing part. The water in the main liner can be heated 110 DEG C on the condition that pressure received by the main liner is low, so that the liner manufacturing cost is reduced, and the use safety of the whole water boiler can be improved.

Description

technical field [0001] The invention relates to the technical field of water heater manufacture, in particular to a closed water boiler. Background technique [0002] At present, most of the water boilers on the market are open, and the maximum water temperature after heating will not exceed 100°C. However, in some applications, the heated water temperature is required to exceed 100°C. For example, in the European market, there are closed water boilers. The maximum temperature after heating reaches 110°C; however, this kind of closed water boiler requires a high pressure resistance of the inner tank due to the large expansion of the volume after the water is boiled. Usually, it needs to be made of special aviation titanium alloy materials, and the manufacturing cost High, and at the same time because of the high pressure of the inner tank, it is also prone to safety accidents. Contents of the invention [0003] The technical problem to be solved by the present invention i...
