Abstract

The utility model discloses an electric water heater, in particular to a preheating and instantaneous dual-mode electric water heater which can be used in preheating and instantaneous ways. The electric water heater is internally equipped with a preheating inner tank and an instantaneous inner tank of a heater, and a dry-fire protection switch and an overheating protection switch are arranged on the preheating inner tank and the instantaneous inner tank. The electric water heater is characterized in that a water inlet of the preheating inner tank is connected with a cool water inlet pipe, an inner tank connecting pipe is connected between a water outlet of the preheating inner tank and a water inlet of the instantaneous inner tank, a water outlet of the instantaneous inner tank is connected with a hot water outlet pipe, the cool water inlet pipe is a main water inlet pipe of the water heater, and the hot water outlet pipe is a main water outlet pipe of the water heater. The electric water heater combines advantages of a preheating electric water heater and an instantaneous electric water heater, and then main power is limited by a little, and thereby the electric water heater can be used in winter, which not only can be used as the preheating electric water heater, but also can be used as the instantaneous electric water heater.

Description

The pre-double mode electric heater of instant heating

Technical field

The utility model relates to a kind of electric heater, the double mode electric heater of pre-instant heating 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; But though fast, the little plug and play of volume of immediate heating type electric heater heating, but be subjected to the influence of environment temperature bigger, particularly under the lower situation of winter temperature, want to be issued to desirable water temperature at the instant heating state, requirement has bigger power, 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, general power is restricted, can be very not big, also can satisfy use under the lower situation of winter temperature, can work as immediately heating water heater uses, also can work as pre-heated water heater and use, again can be in advance with the double mode electric heater of pre-instant heating that uses by Instant heating type supplementary heating behind the water preheat.

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 of 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.

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 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 was the heating of pre-heated inner bag, Instant heating type inner bag was not worked, and will be stored in the cold water heating in the pre-heated inner bag in advance, and when using hot water, pre-heated inner bag is not worked, and as hot water amount's deficiency, was replenished by Instant heating type inner bag heating; When two of mode of operation was the work of Instant heating type inner bag, pre-heated inner bag was not worked, and cold water enters Instant heating type inner bag by pre-heated inner bag, was flowed out for use 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, can be in advance carry out preheating to the hot water of a large amount of storages, can supply water immediately when using hot water a small amount of again, reach purpose easy to use, effective energy savings.

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 inner bag 2 is connected with hot water outlet pipe 9.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.

When this water heater is set to preheating mode, pre-heated inner bag 1 heating, Instant heating type inner bag 2 is not worked, 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, after heating is finished, cold water enters pre-heated inner bag 1 from cold water inlet 3, and pre-heated inner bag 1 quits work; Instant heating type inner bag 2 begins heating, and hot water flows out for using from hot water outlet pipe 9, and the hot water amount of 2 pairs of pre-heated inner bags 1 of Instant heating type inner bag this moment carries out instant supplementary heating, makes hot water can continue to flow out from hot water outlet pipe 9.If the water temperature in the pre-heated inner bag 1 is satisfied the demand, Instant heating type inner bag 2 can not worked yet, and the water in the pre-heated inner bag 1 gets final product from hot water outlet pipe's 9 outflows directly through Instant heating type inner bag 2.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, and cold water, enters Instant heating type inner bag 2 and heats immediately behind pre-heated inner bag 1 from cold water inlet 3, and hot water flows out for using from hot water outlet pipe 9.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.
