Abstract
The utility model relates to an external heater for water drinking machine. An external heating assembly of a water drinking machine is composed of a pair of bush-shaped heating bodies which have symmetrical structure and can be interchangeably assembled from left to right and a hyperbola-shaped electric heating tube which is cast into a whole with the bush-shaped heating bodies, and the external heating assembly is fastened on the external of the tank body of the water drinking machine through a connecting clamp. The external heater has the advantages of simple mould structure, simplified processing technology and assembly technology, convenient maintenance and reduced manufacture cost, and the small heat resistance, high electric heating conversion efficiency, long working service life, safety and other characteristics of the external heating mode are maintained at the same time. The utility model is an advanced product in the heating modes of the present water drinking machines and can save materials and energy.
Description
The utility model relates to the water dispenser heater structure.
Water dispenser is to be the supply equipment that water container raises water temperature by Electric heating with the stainless steel bucket.Its mode of heating has built-in and external, because the external heater can be avoided the defective that directly contacts with water and replace built-in heating gradually.The external heating is a mode of heating of being close to staving energising heating by heater, divides end heating, the heating of mica formula electric heating coil and hinge type outer heater heating again.End heating is made complicated, need open screwed drainpipe in the stainless steel bucket bottom, needs to isolate staving bottom and support with heat shield, and copper nut is fastening, thus many with material, require also higher to staving; The heating of mica formula electric heating coil is present domestic most widely used mode of heating, it be one with mica as insulating materials, iron sheet or stainless steel substrates are pressed as outer geosphere and are formed, its defective is that electric conversion efficiency is low, working life is short, air enter easily the circle in and the continuous oxidation of heating wire is blown, and general employing of mica formula electric heating coil made by hand, be unfavorable for producing in batches, consistency of product is relatively poor, so cost is higher, simultaneously, mica is big as its thermal resistance of insulating materials, and electric heating coil surface temperature height (generally will reach more than 300 ℃) causes the influence of water dispenser peripheral element big; The outer heater of hinge type is existing abroad to be adopted, and it is formed by connecting with hinge arrangement by the aluminium die casting calandria of two bearing shell shapes, can not exchange assembling because left and right sides calandria structure is asymmetric, make aluminium casting forming mould complexity, assembling speed is slow, and is many with material, the cost height.
The utility model be intended to overcome the defective of prior art and provide a kind of make simple, assembling is simple and easy, the outer heater of water dispenser of being convenient to maintaining, low cost of manufacture.
The realization the technical solution of the utility model is: comprise calandria, be to draw the electrothermal tube that can connect power supply having of die casting one in the calandria, be fastened on outside the water dispenser staving by jointing clip, but its improvements are described calandria and are designed to a pair of bearing shell shape calandria of symmetrical configuration right and left mutually changing assembling that the electrothermal tube in its calandria is the hyperbolical electrothermal tube.
But the utility model is owing to adopted the bearing shell shape calandria and the hyperbolical electrothermal tube of the assembling of symmetrical configuration right and left mutually changing, so mould only needs one pair and simple in structure, processing technology and assembly technology are all simplified, be convenient to maintaining again, thereby cost of manufacture is reduced greatly, the thermal resistance that has kept the external mode of heating simultaneously is little, electric conversion efficiency is high, long working life, characteristics such as safe and reliable, is not only to have economized material but also energy-conservation advanced product in the present water dispenser mode of heating.

In conjunction with above-mentioned accompanying drawing embodiment of the present utility model is remake following detailed description.
Shown in Fig. 1-8, but the outer heater of water dispenser comprises the bearing shell shape calandria (1) of a pair of symmetrical configuration right and left mutually changing assembling, calandria is material with the aluminium alloy, and is built in the calandria and the hyperbolical electrothermal tube (3) of die cast constitutes the heating component of water dispenser external.The hyperbolical electrothermal tube becomes hyperbolical by hollow copper facing iron pipe dish, in be provided with the CrFe alloy elastic yarn (9) of coiling and by high temperature magnesium powder charges (8) filling, the welded post that draw the end (5) is by high-temperature silica gel encapsulant (7) encapsulation, and the wiring board (6) that can connect power supply is fixing with the welded post welding.
In order to improve the thermal efficiency, heater must contact closely with staving, so the jointing clip (2) by belt is fastened on outside the water dispenser staving, in order to reach the elasticity that better is fastenedly connected and increases calandria, neck at a pair of calandria is provided with eyelet (4), jointing clip (2) is fastened on bearing shell shape calandria (1) neck through eyelet (4), be connected by connector plus screw, spring washer and rectangle nut, calandria is subjected to closely to contact on the water dispenser staving with regard to producing distortion after the fastening force effect.
Claims (3)
1. the outer heater of a water dispenser, comprise calandria (1), be provided with in the calandria and draw the electrothermal tube (3) that can connect power supply having of die casting one, be fastened on outside the water dispenser staving by jointing clip (2), it is characterized in that but described calandria is a pair of bearing shell shape calandria (1) of symmetrical configuration right and left mutually changing assembling, the electrothermal tube in the calandria is hyperbolical electrothermal tube (3).
2. the outer heater of water dispenser as claimed in claim 1 is characterized in that described bearing shell shape calandria (1) is provided with eyelet (4) on neck, and jointing clip (2) is fastened on the calandria neck through eyelet.
