Abstract

The utility model discloses a water-storage-type electric water heater with adjustable water level, which is characterized in that: by choosing one or a plurality of effluent branches 6, 8 with valves 7, 9 for horizontal height of a water outlet, water saving adjusting can be met and appropriate water capacity can be get through opening and closing the effluent branches because of different horizontal height of upper openings for the effluent branches. The utility model also provides an air intake route 10 and a valve 11 for air intake and water discharge when adopting closed water vessel. The utility model can avoid water drip when heating.

Description

A kind of storage-type electric water heater of adjustable water level

The utility model relates to a kind of storage-type electric water heater, especially a kind of storage-type electric water heater of adjustable water level.

In order to prevent dry combustion method and easy to use, the water inlet of most storage-type electric water heaters has adopted the check valve of only import but no export, delivery port has been set certain altitude, water in the storage-type electric water heater in so normal use remains on below the horizontal line of delivery port position, and its moisture storage capacity is a constant volume.People are different to the demand of hot water under the different situations condition.Such as the difference in season; Family population changes etc.: we suppose that end user's family has 4 people, have selected suitable capacity for use.If but have 3 people to go out the several months, and just 1 people that is in, during this, the end user keeps and often opens electric heater, the waste holding power; If separated usefulness, but that it(?) still must be to the heating of whole bucket water when using will wait longer heat time heating time and uses the electric power of unnecessary heating.Two kinds of methods have all wasted heat time heating time, add thermopower and keep the electric power of water temperature.

The purpose of the storage-type electric water heater of a kind of adjustable water level of the present utility model provides the electric heater that a kind of end user of making can regulate the water storage water level, allow the end user can pass through to select the water level difference to reach, choose different capacity, to use the waste of minimizing time and electric power near own suitable capacity.

For achieving the above object, the technical scheme of electric heater of the present utility model is: this electric heater has the delivery port of regulating level height or the different branch road of outlet pipe mouth of pipe level height that opens and closes with selecting of existing side by side of outlet pipe is arranged, can determine its outlet pipe level height or select one or several above-mentioned outlet pipe branch road of existing side by side by required water level, to reach the purpose of control water storage capacity.The container of more electric heater has adopted whole air-tight manner except the water-in and water-out pipe valve in order to keep tap water pressure, electric heater of the present utility model has the air inlet pipe of a band pipe valve, when adopting than the low water level of original water level, open this pipe valve and close into water pipe valve, can during normal use emit the water that exceeds water level; Use can be closed the venting pipe valve during than the high water level of former water level, and opens that the inlet tube and outlet tube pipe valve can be intake by water inlet, the delivery port venting is flooded and it is airtight to keep, guarantee the pressure transmission.

The utility model can make the end user turn down the delivery port height a few water period, reduces the water storage capacity, plays the effect of saving heat time heating time and adding thermopower.When urban water demand is big, can increase the method for moisture storage capacity by heightening outlet pipe mouth of a river height of water level again, improve rated capacity, satisfy and use.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the schematic diagram that a kind of storage-type electric water heater that can be used for closed container of the present utility model adopts the embodiment of three water levels.

Embodiment example of the present utility model is by water receptacle 1, inlet pipeline 2, and water inlet check valve 3, outlet pipeline 4, electric heater 5 constitutes basic storage-type electric water heater.It also comprises outlet pipe one branch road 6 of existing side by side, the outlet pipe one branch road water pipe valve 7 of existing side by side, outlet pipe two branch roads 8 of existing side by side, the outlet pipe two branch road water pipe valves 9 of existing side by side; Air inlet pipe 10, air inlet pipe valve 11; And water inlet pipe valve 12.By among Fig. 1 as can be seen, outlet pipe divides the mouth of a river height of water level of branch road to be lower than outlet pipe 4 mouth of a river heights of water level.The air inlet pipeline of this embodiment utilizes outlet pipe 4 dual-purposes.The technical process of this embodiment of the present utility model is achieved in that when not opening when existing side by side outlet pipe branch road water pipe valve, electric heater is once normal use, water inlet is entered in the water receptacle 1 by check valve 3 by inlet pipeline 2, waterline is in outlet pipe 4 mouth of pipe horizontal line positions, and at this moment the water capacity of electric heater is exactly a rated capacity; When the water pipe valve 7 of outlet pipe one branch road 6 of existing side by side is opened, the level height of outlet pipe one branch road 6 is low owing to exist side by side, and water outlet is flowed out from outlet pipe one branch road 6 of existing side by side, because the aqueous vapor that general running water contains gas and heating turns usefulness into, even closed container, water level also can progressively descend.In order to accelerate water level decrease speed in this case, this embodiment can be closed into water pipe valve 12, open air inlet pipe valve 11, water uses container water merely, and the vacuum suction ambient pressure that the water outflow produces enters container by admission line 10, air inlet pipe valve 11, outlet conduit 4.When water level drops to when existing side by side outlet pipe one branch road pipeline 6 delivery port horizontal levels, water outlet stops, and can close air inlet pipe valve 11 this moment, opens into water pipe valve 12, and the moisture storage capacity of electric heater will keep by this water level, and keep system's hydraulic pressure.When selecting water level to press outlet pipe two branch road delivery port horizontal lines, can open two outlet pipe branch road pipe valves 9, the same branch road of use principle, waterline remain on two outlet pipe branch roads, 8 delivery port levels.By parity of reasoning, can obtain many water level controls.

In addition, present open storage-type electric water heater is simple shower, and because of its delivery port is opened all the time, but the requirement of housing dispense pressure can reduce cost.But require the end user water pipe valve not to be set at delivery port.Like this after turning off into the water pipe valve, in heating process, because of water body expansion from shower head do not stop to have dripped common fault into this class electric heater.Use of the present utility modelly when electric heater is provided as open water heater, open a low-water level switch during use, make it in use reduce water level naturally, close low-water level switch when inactive, can prevent fully that open water heater heating from dripping.
