背景技术Background technique
目前市场上的电热水装置都是使用电发热管浸泡在水中加热方式对水进行加热，随着使用的时间增加，电发热管表面会结水垢，时间越长水垢越厚，致使电发热管热量传导性能降低、能效变低，甚至出现烧断电发热管内发热丝、电发热管表面金属管爆裂进水造成漏电等现象，电发热管容易损坏，极不耐用。At present, the electric water heating devices on the market use electric heating tubes soaked in water to heat the water. As the use time increases, the surface of the electric heating tubes will be scaled. The longer the time, the thicker the scales, resulting in the heating of the electric heating tubes The conductivity is reduced, the energy efficiency becomes lower, and even the heating wire in the electric heating tube is burned out, and the metal tube on the surface of the electric heating tube bursts and water enters, causing electric leakage. The electric heating tube is easily damaged and extremely not durable.

具体实施方式Detailed ways
如图1-3所示，一种复合型电热水装置，包括有压铸成型的导热体1，导热体1内封装有导热盘管2和电热元件3，导热盘管2的两端分别连接进水口4和出水口5，电热元件3的发热体容置在导热盘管2所盘绕成的空间内，导热体1的外表面固定有贴合的平面电热元件6。电热元件3的发热体部分插入导热盘管2所盘绕成的空间内，利用热熔的导热材料(比如铝合金)压铸成一实体，压铸成型的铝合金为导热体1，导热盘管2和电热元件3封装在导热体1内，电热元件3的接线端子外露。电热元件3的热量会通过导热体1传到导热盘管2，进而加热流经导热盘管2内的水。再加上固贴在导热体1表面的平面电热元件6，形成了对导热体1的复合型加热方式，可有效提升电热水装置的加热速度。本发明电热水装置的电热元件都没有浸泡水中，彻底杜绝了传统电热水装置结水垢的问题，有效延长电热水器的使用寿命。其中的导热盘管2可采用不锈钢管盘绕而成，不锈钢管成形折弯半径小，易弯且成形后盘绕的空间小，可节省压铸铝合金用材。As shown in Figure 1-3, a composite electric water heater includes a heat conductor 1 formed by die-casting. The heat conductor 1 is packaged with a heat conduction coil 2 and an electric heating element 3. The two ends of the heat conduction coil 2 are respectively connected into The water outlet 4 and the water outlet 5, and the heating element of the electric heating element 3 are accommodated in the space formed by the heat conduction coil 2, and the outer surface of the heat conductor 1 is fixed with a planar electric heating element 6 attached thereto. The heating body part of the electric heating element 3 is inserted into the space coiled by the heat conduction coil 2, and is die-cast into a solid body by using a hot-melt heat conduction material (such as aluminum alloy). The element 3 is encapsulated in the heat conductor 1, and the connection terminals of the electric heating element 3 are exposed. The heat of the electric heating element 3 will be transferred to the heat conduction coil 2 through the heat conductor 1 , and then the water flowing through the heat conduction coil 2 will be heated. Coupled with the planar electric heating element 6 fixed on the surface of the heat conductor 1, a composite heating method for the heat conductor 1 is formed, which can effectively increase the heating speed of the electric water heater. The electric heating elements of the electric water heating device of the present invention are not soaked in water, completely eliminates the problem of scaling in the traditional electric water heating device, and effectively prolongs the service life of the electric water heater. The heat-conducting coil 2 can be formed by coiling stainless steel tubes. The stainless steel tubes have a small bending radius, are easy to bend, and have a small coiling space after forming, which can save die-casting aluminum alloy materials.
具体的，所述平面电热元件6为远红外电热板，其热辐射面对着导热体1。远红外电热板发热效率高，具有定向辐射发热的功能，将其热辐射面对着导热体1可有效提升加热效率。优选的，所述远红外电热板可采用性能更加优异的远红外陶瓷电热板。所述电热元件3可采常规的电热管。Specifically, the planar electric heating element 6 is a far-infrared electric heating plate, and its heat radiation surface faces the heat conductor 1 . The far-infrared electric heating plate has high heating efficiency and has the function of directional radiation heating, and the heating efficiency can be effectively improved by facing the heat radiation surface to the heat conductor 1 . Preferably, the far-infrared electric heating plate can use a far-infrared ceramic electric heating plate with more excellent performance. The electric heating element 3 can adopt a conventional electric heating tube.
在本实施例中，所述导热盘管2设有并联的多组，亦即是分成多段盘绕，每一段的两端都分别并联到同一个进水口4和出水口5。这样，既可减少导热盘管2的管径，又不会影响到整个电热水装置的热水流量。减少的管径可极大地提升对水的加热速度。In this embodiment, the heat conduction coils 2 are arranged in multiple groups connected in parallel, that is, they are coiled in multiple sections, and both ends of each section are connected in parallel to the same water inlet 4 and water outlet 5 respectively. In this way, the pipe diameter of the heat conduction coil 2 can be reduced without affecting the hot water flow of the entire electric water heater. The reduced pipe diameter can greatly increase the heating rate of water.
为了本发明电热水装置的外形超薄美观，提高能效，可将导热盘管2盘绕成扁体状，这样就可将导热体1压铸成扁方体状。盘绕成扁体状的导热盘管2就可形成长扁形的空间，这样就可在该空间内插置多支排成一排的电热元件3，进一步地提升加热速度。并且扁方体状导热体1的侧面具有更有利于贴合固定平面电热元件6的平面。In order to have an ultra-thin and beautiful appearance of the electric water heating device of the present invention and improve energy efficiency, the heat conduction coil 2 can be coiled into a flat body shape, so that the heat conduction body 1 can be die-cast into a flat body shape. The heat conduction coil 2 coiled into a flat shape can form a long and flat space, so that a plurality of electric heating elements 3 arranged in a row can be inserted in the space to further increase the heating speed. And the side of the flat parallelepiped heat conductor 1 has a plane that is more conducive to bonding and fixing the plane electric heating element 6 .
