Abstract

The utility model discloses an electric water heater with two chambers, which relates to an electric water heater and is composed of a casing, a conversion valve and a water mixing valve. A moving partition board is arranged in the casing to divide the casing into two chambers, both sides of the moving partition board are both provided with a one-way valve, and pressing blocks are arranged on the inner walls of the sides of the casing corresponding to the positions of the one-way valves. The bottoms of the two chambers are both provided with a water opening, the tops of the two chambers are both provided with a venting plug, and a heater and a temperature control device are both arranged in each chamber. The conversion valve is connected with the water openings of the two chambers and the water mixing valve through a water tube, and the water mixing valve and the conversion valve are both connected with a cold water tube. The utility model has the advantages of short heating time of cold water, stable water temperature when the utility model is used and high utilization rate of hot water.

Description

The dual cavity electric heater

The utility model relates to electric heater.

At present, the electric heater of selling on the domestic market is which kind of brand no matter, is single barrel of single chamber thermal-insulating type, in use has some defectives.At first the thermal source waste is bigger, and heat time heating time is long; Next advances cold water and goes out hot water and carry out simultaneously, and hot and cold water is in ladle mixing, and rate of thermal water utilization is low; Because when emitting hot water, promptly enter cold water in the bucket, water temperature causes the water temperature instability reducing gradually, need the limit to regulate during bathing and mix water valve with the waterside, very inconvenient.

The purpose of this utility model is the shortcoming that overcomes existing electric heater, provides a kind of heat time heating time short, the dual cavity electric heater of rate of thermal water utilization height, water temperature stability.

For achieving the above object, the utility model adopts following solution.

The dual cavity electric heater is made up of housing, switching valve and mixed water valve, be provided with active clapboard in the housing housing is divided into two chambers, the active clapboard two sides is equipped with check valve, on the housing side inner walls, be provided with briquetting with the check valve correspondence position, two cavity bottom are equipped with the mouth of a river, the top is equipped with venting plug, heater all is housed in each chamber and temperature control equipment is housed; Switching valve is connected by water pipe with the mouth of a river and the mixed water valve of two chambers, mixes water valve and all is connected with cold water pipe with switching valve.

Switching valve is made up of valve body and spool, and valve body is provided with water inlet, delivery port and two chamber interfaces, and its end is provided with end cap; Spool is installed in the valve body, and its cross section is " X " type.Rotational valve core can realize that water inlet is communicated with another chamber interface simultaneously with a chamber interface and delivery port or delivery port is communicated with another chamber interface simultaneously with a chamber interface and water inlet.

During use,, screw on again after the topped up with water if a large amount of water is opened the venting plug of two chamber roof with exhaust earlier.Connect power supply temperature is transferred to certain numerical value.When a chamber reaches water temperature, rotate switching valve this accent is communicated with delivery port, to discharge hot water.Along with the minimizing of this chamber water yield, active clapboard moves to this chamber under the effect of another chamber hydraulic pressure gradually, moves to certain position, and the check valve on the active clapboard is backed down by jacking block, two chamber intercommunications, and the water of another chamber flow to this chamber.Rotate the switching valve spool and make another chamber discharge hot water, if need to give simultaneously the chamber that uses up hot water to continue heating, the hot water in such two chambers uses in turn.If a small amount of water, then that the water yield is a few chamber are heated to use after the uniform temperature and get final product.

Be provided with two chambers in the such scheme of the present utility model, can heat cold water simultaneously, use in turn, shortened heat time heating time, the water temperature stability when having guaranteed to use has improved rate of thermal water utilization, adapts to the needs of various water consumptions.

The utility model is described in further detail below in conjunction with drawings and Examples.

Wherein: 1, housing 2, venting plug 3, check valve 4, sealing ring 5, active clapboard 6, jacking block 7, temperature control equipment 8, heater 9, the mouth of a river 10, safety valve 11, switching valve 12, mix water valve 13, cold water pipe 14, hanger 15, magnet piece 16, ball 17, ball rack 18 valve bodies 19, delivery port 20, sealing ring 21, spool 22, one chamber interface 23, another chamber interface 24, water inlet 25, end cap 26, knob.

Embodiment:

Fig. 1 has provided structural representation of the present utility model.Be provided with active clapboard 5 in the housing 1, two chambers about housing 1 inside is divided into.Have sealing ring 4 on the active clapboard 5, be equipped with check valve 3 on its two sides, block board thickness should make its unlikely deflection under the hydraulic pressure effect.Be provided with jacking block 6 with check valve 3 corresponding positions on each chamber inner wall, when removable cover 5 moved on to the dotted line place, jacking block 6 backed down check valve 3.For the ease of observe the position that active clapboard 5 moves in bucket, in dividing plate, be provided with magnet piece 15 (as shown in Figure 2), be provided with the ball rack 17 consistent in housing 1 outside with magnet piece 15 relevant positions with the dividing plate moving direction, ball 16 is housed in it.According to the position of dividing plate as can be known, the position of ball, housing 1 outside also is provided with hanger 14.Heater 8 and temperature control equipment 7 all are housed in two chambers, and venting plug 2 is equipped with at the top, and the mouth of a river 9 is equipped with in the bottom.Switching valve 11, mixed water valve 12 and the two chamber mouths of a river couple together by water pipe, and cold water pipe 13 all is connected with mixed water valve 12 with switching valve 11.Hot and cold water mixes the back and discharges use in mixed water valve 12.Also be connected to safety valve 10 on the water pipe in switching valve 11 and being connected of chamber.Fig. 2 and Fig. 3 provide the structural representation of switching valve, it is made up of valve body 18 and spool 21, valve body 18 is provided with water inlet 24 (being connected with cold water pipe 13), delivery port 19 (being connected with mixed water valve) and two chamber interfaces 22,23 (being connected with the two chamber mouths of a river respectively), has sealing ring 20 on the spool.As can be seen from Figure 3, end cap is housed also on the valve body 18, knob 26 is housed on the spool 21 with rotational valve core.During a small amount of water of the utility model, need emit certain water yield for heating as early as possible, switching valve can be designed to two chamber interface intercommunications, for not wasting the water source, can add two-way micro pump on the water pipe between the two chamber mouths of a river and switching valve two chamber interfaces.
