Abstract
The utility model discloses an instant water heater which comprises an electric heater and a heat exchanger. The electric heater comprises an electric heating element and a wiring board, the electric heating element is electrically connected with a wiring terminal arranged on the wiring board, and the heat exchanger is a spiral hollow tube. Thermal-conductive medium is filled between the electric heater and the heat exchanger. Therefore, heat exchanging between the electric heater and the heat exchanger is sufficient. In addition, heated water flows in the heat exchanger only and does not directly contact with the electric heater, scales less easily accumulate in the electric heater, and the wall of an electric heating tube is prevented from being burned through.
Description
Technical field
The utility model relates to Instant heating type hot water apparatus.
Background technology
The electric heating water boiling utensils such as the electric heater of instant heating, electric hot water tap are accepted by increasing people owing to have than the like product of storage-type more power saving and the plurality of advantages such as little of can using at any time, take up room.The hot water apparatus of the electric heating water boiling utensils such as present most instant electric water heater, electric hot water tap all adopts the contacted mode of cold water in electrothermal tube and the container.The bottom of container is provided with the water inlet top and is provided with delivery port.Surface temperature is very high in the course of the work owing to electrothermal tube, is easy to form incrustation scale on its surface.When the extremely low scale build-up of thermal conductivity factor arrived certain degree, the heat that electrothermal tube produces can not be absorbed by water timely.The overheated electrothermal tube tube wall that causes easily of electrothermal tube burns, and the situation that causes leaking electricity occurs.On the other hand, when delivery port stops up or control system when breaking down, the water temperature in the container constantly raises, and innerly can produce larger pressure, finally causes the container explosion.
The utility model content
The purpose of this utility model provides a kind of Instant heating type hot water apparatus.
According to an aspect of the present utility model, Instant heating type hot water apparatus is provided, comprise electric calorifie installation and heat-exchanger rig.Electric calorifie installation comprises heating and terminal plate, and heating and the binding post of being located on the terminal plate are electrically connected, and heat-exchanger rig is helically wound hollow pipe.Be filled with the good heat-conducting medium of thermal conductive property between electric calorifie installation and the heat-exchanger rig.Thus, between electric calorifie installation and the heat-exchanger rig heat exchange more abundant, simultaneously, heated water only flows in heat-exchanger rig, does not directly contact with electric calorifie installation, electric calorifie installation is difficult for incrustation, the phenomenon of having avoided the electrothermal tube tube wall to burn.
In some embodiments, heating is the U-shaped electrothermal tube.
In some embodiments, the two ends of U-shaped electrothermal tube are connected with two terminal plates.Terminal plate is provided with the same number of binding post with the U-shaped electrothermal tube, and binding post is electrically connected with the U-shaped electrothermal tube respectively.Thus, binding post can be connected the U-shaped electrothermal tube with control circuit independently respectively one by one.This device can be controlled respectively by external circuit the duty of U-shaped electrothermal tube, reaches the purpose of regulating heating power.
In some embodiments, the heat-exchanger rig helical disk is located at around the electric calorifie installation.Thus, can improve the direct heat exchanger effectiveness of electric calorifie installation and heat-exchanger rig.
In some embodiments, heat-exchanger rig adopts 304 stainless steel manufacturings.Thus, the effective heat exchange area of heat-exchanger rig is large, and structure is more reliable and more stable.
In some embodiments, heat-conducting medium is aluminium.
In some embodiments, electric calorifie installation and described heat-exchanger rig and heat-conducting medium are made an integral body by forging type.Thus, this Instant heating type hot water apparatus bearing capacity is higher, and the phenomenon of booster can not occur.
