Abstract

The utility model discloses a capacitance variation electric water heater. The utility model comprises a shell body, wherein an inner liner of the shell is divided into two or more independent cavity bodies by heat insulation plates, each two adjacent cavity bodies are mutually communicated through a water guide pipe, a heater and a water outlet pipe are respectively arranged in each of the cavity bodies, a water inlet pipe is communicated with any cavity body, and a multi-ported switching valve is arranged on the external side of the shell and is communicated with each water outlet pipe; the water inlet ends of the water guide pipes are positioned at the top parts of the cavity bodies, and the water outlet ends of the water guide pipes are positioned at the bottom of the adjacent cavity bodies. According requirements, water in different cavity bodies of the capacitance variation electric water heater can be respectively or synchronously heated, and the utility model has the advantages of quick hot water discharge, little waste and energy saving.

Description

The variable displacement type electric heater

The utility model relates to a kind of electric heater.

At present, existing electric heater, because volume is certain, can not change the inner heated water capacity of water heater, the various needs that can not adapt to people, for example, season is different or use the different required hot water amounts of number of hot water also different, still, even need the also necessary at present water that heats in the whole water storage tank of a spot of hot water, so, the time that adds hot water is long, also must consume a large amount of electric energy when needs are incubated, exhaustless hot water is cooled off in vain, cause waste of energy, and shortcomings such as hot water is under-supply can appear in the little water heater of capacity, bring numerous inconvenience to people's life.

The purpose of this utility model provides a kind of variable capacity formula electric heater, satisfies people and uses how much hot water, heats the needs of how much hot water, plays the effect of saving electric energy.

The technical solution of the utility model is, a kind of variable displacement type electric heater, it comprises housing, by thermal insulation board inner bag is separated into two or more cavity independent of each other in the housing, two adjacent cavitys are interconnected by aqueduct, equal having heaters in each cavity, and water inlet pipe is communicated with a certain cavity, all set out water pipe in each cavity, being connected at multi direction changeover valve of outer setting and each outlet pipe of housing constitutes the hot water drainage channel corresponding with the cavity number.

The utility model compared with prior art, when using a small amount of hot water, can distinguish the water in the different cavitys in the heating volume-variable electric heating water heater, also can heat the water in each chamber as required simultaneously, the multi direction changeover valve of the outer setting of suitable adjustment housings during use, can be by each outlet pipe and multi direction changeover valve with the hot water emission in its place chamber, it is fast to the utlity model has out hot water, energy savings, practical and convenient advantage.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment

As shown in Figure 1, the variable displacement type electric heater, it comprises housing 10, with thermal insulation board 11 inner bag is separated into a left side independent of each other in the housing 10, right two cavitys, two cavitys are interconnected by aqueduct 20, the water inlet end of aqueduct 20 is positioned at the top of right cavity, the water side is positioned at the bottom of left cavity, equal having heaters 60 in each cavity, water inlet pipe 30 is communicated with right cavity bottom, all sets out water pipe 40 in each cavity, is connected with each outlet pipe 40 at three-way switch valve 50 of outer setting of housing 10, when a small amount of hot water of needs, open the heater 60 in the left cavity, the water in the left cavity is heated, reach design temperature after, open and mix valve switch and three-way switch valve 50, hot water flows out from the outlet pipe 40 in the left cavity; When needs more amount hot water, open the heater 60 in the right cavity, the water in the right cavity is heated, reach design temperature after, open and mix valve switch and three-way switch valve 50, hot water flows out from the outlet pipe 40 in the right cavity; When the more hot water of needs, the heater 60 in the left and right cavity is open-minded simultaneously, about water in two cavitys all be heated, when reaching design temperature, open and mix valve switch and three-way switch valve, the outlet pipe 40 of hot water in left and right cavity flows out respectively.

By above-mentioned explanation as can be known, the cavity of water heater is divided into the form of multi-cavity chamber with thermal-insulation baffle plate, add heater in it, and in each chamber, set out water pipe, it is guided to hull outside cooperates with multi direction changeover valve and causes supply channel, constituted thus that a multi-cavity chamber can be distinguished or the water heater of hot-water supply simultaneously, thus satisfied people's needs how much hot water just heating what, save electric energy and water resource simultaneously effectively.

Claims
