Description

Pre-Instant heating type energy-saving electric water heater

Technical field

The utility model relates to a kind of electric heater, the pre-Instant heating type energy-saving electric water heater that especially a kind of preheating instant heating is dual-purpose.

Background technology

Existing electric heater is divided into two kinds of preheating type and immediate heating types.Wherein preheating type electric heater power is low, moisture storage capacity is big, but its volume is big, heat time heating time is long, need heat in advance and be incubated, can not plug and play, so be inevitable for the waste of electricity; But though fast, little, the power saving plug and play of volume of immediate heating type electric heater heating, but be subjected to the influence of environment temperature bigger, water temperature was not enough when particularly used winter, wanted the water temperature that reaches desirable, power just must be very big, and general family has no idea to install and use.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of advantage that combines preheating type and immediate heating type electric heater, and the needs in the time of can satisfying urgently needed hot water can will use behind the water preheat again in advance, can effectively save the pre-Instant heating type energy-saving electric water heater of water power.

The technical scheme in the invention for solving the above technical problem is: the pre-heated inner bag and the Instant heating type inner bag that are provided with heater in this electric heater comprises, on pre-heated inner bag and Instant heating type inner bag, also be provided with anti-dry protection switch and overtemperature prote switch, its design feature is that the water inlet at pre-heated inner bag is connected with cold water inlet, be connected with the inner bag tube connector between the delivery port of pre-heated inner bag and the water inlet of Instant heating type inner bag, the delivery port of Instant heating type inner bag is connected with the hot water outlet pipe; And be connected with the water pipe of intercommunication between cold water inlet and inner bag tube connector, be provided with magnetic valve on water pipe, the water inlet of magnetic valve links to each other with the water inlet of pre-heated inner bag, and the delivery port of magnetic valve links to each other with the water inlet of Instant heating type inner bag.

Cold water inlet described in the utility model is the water inlet manifold of water heater, and the hot water outlet pipe is total outlet pipe of water heater.

The utility model is provided with the water outlet limiter at the delivery port place of pre-heated inner bag.

The utility model compared with prior art, has following beneficial effect: Instant heating type inner bag and pre-heated inner bag are cascaded by pipeline, pre-heated inner bag is provided with the cold water inlet as water inlet manifold, and Instant heating type inner bag is provided with the hot water outlet pipe as total outlet pipe; When one of mode of operation is the heating of pre-heated inner bag, Instant heating type inner bag is not worked, to be stored in the cold water heating in the pre-heated inner bag in advance, when using hot water, pre-heated inner bag is not worked, hot water in the pre-heated inner bag mixes behind the cold water that magnetic valve flows into through limiter, enters Instant heating type inner bag and carries out heat make-up; When two of mode of operation is the work of Instant heating type inner bag, pre-heated inner bag is not worked, cold water enters Instant heating type inner bag by pre-heated inner bag, this moment, magnetic valve was in closed condition, the preheating inner bag only uses as a pipeline this moment, cold water directly enters Instant heating type inner bag through limiter, is flowed out for using from hot water outlet by Instant heating type inner bag heating back.More than two kinds of mode of operations be fit to the needs of Various Seasonal and occasion, both can be in advance the hot water of a large amount of storages be carried out preheating, can when a small amount of use hot water, supply water immediately again, reach purpose easy to use, effective energy savings.Limiter can limit water yield simultaneously, magnetic valve is controlled current, makes its heating better effects if, more effective saving water power.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

Referring to Fig. 1; present embodiment comprises pre-heated inner bag 1 and Instant heating type inner bag 2; be provided with pre-heated inner bag heater 7 in the pre-heated inner bag 1; be provided with Instant heating type inner bag heater 6 in the Instant heating type inner bag 2, anti-dry protection switch 4 and overtemperature prote switch 5 all are installed on pre-heated inner bag 1 and the Instant heating type inner bag 2.The water inlet of pre-heated inner bag 1 is connected with cold water inlet 3, is connected with inner bag tube connector 8 between the water inlet of the delivery port of pre-heated inner bag 1 and Instant heating type inner bag 2, and the delivery port of Instant heating type interior 2 courages is connected with hot water outlet pipe 9.And between cold water inlet 3 and inner bag tube connector 8, be connected with the water pipe 11 of intercommunication in parallel, on water pipe 11, be provided with magnetic valve 10, magnetic valve water inlet 12 links to each other with the water inlet of pre-heated inner bag 1, and magnetic valve delivery port 13 links to each other with the water inlet of Instant heating type inner bag 2.Wherein cold water inlet 3 is the water inlet manifold of this water heater, and hot water outlet pipe 9 is total outlet pipe of this water heater.Delivery port place at pre-heated inner bag 1 is provided with water outlet limiter 14.

When this water heater is set to preheating mode, pre-heated inner bag 1 heating, Instant heating type inner bag 2 is not worked, and the cold water that pre-heated inner bag 1 will store within it in advance is heated in the temperature of overtemperature prote switch 5 restrictions.During water, cold water enters water pipe 11 through cold water inlet 3, magnetic valve 10 is opened, the warm water of preheating in advance is through water outlet limiter 14 in the pre-heated inner bag 1, with enter Instant heating type inner bag 2 after the cold water mix that flows out from magnetic valve delivery port 13, Instant heating type inner bag 2 begins heating, and hot water flows out for using from hot water outlet pipe 9.Water outlet this moment limiter 14 is the water inlet water temperature of the Instant heating type inner bag 2 of proportioning effectively, improve the task performance of Instant heating type inner bag 2, can can not carry out replenishing more effective saving water power immediately simultaneously the water yield in the pre-heated inner bag 1 because of bleeding off the waste that part cold water causes water.This pattern is fit to winter or needs a large amount of occasions of hot water of using to use, and it carries out preheating to cold water in advance, replenishes by instant heating during use again.

When this water heater is set to be heat pattern, Instant heating type inner bag 2 heating, pre-heated inner bag 1 is not worked, magnetic valve 10 disconnects, cold water, enters Instant heating type inner bag 2 and heats immediately behind pre-heated inner bag 1, water outlet limiter 14 from cold water inlet 3, and hot water flows out for using from hot water outlet pipe 9.This moment, water outlet limiter 14 can effectively limit the inflow of Instant heating type inner bag 2, had limited water yield simultaneously, and making is heating better effects if under the heat pattern, more effective saving water power.This pattern is fit to three seasons of spring and summer autumn or needs a small amount of occasion of hot water of using to use, and immediately cold water is heated.

According to different situations, select to use above two kinds of mode of operations, can effectively reach the purpose of energy savings.5 on anti-dry protection switch 4 and overtemperature prote switch are used to protect two inner bags and imbalance state occurs, guarantee its operate as normal, have improved security performance.
