Abstract
The invention relates to an instant electric water heater, in particular to a heating device of the instant electric water heater. The heating device of the ultra-thin instant electric water heater comprises an outer tank body with a water pipe inlet and outlet channel, a PTC (positive temperature coefficient) ceramic is taken as a heating body and is positioned in the outer tank body, the PTC ceramic is in a sheet shape and is clamped by sheet type electrodes which are arranged on the top and bottom surfaces of the PTC ceramic, have consistent size and are connected with wires, and a polyimide film used as an insulating material is coated outside the electrode. The heating device is safe and reliable, is thin and can be washed after being disassembled.
Description
Technical field
The present invention relates to the instant electric water heater, relate in particular to a kind of instant electric water heater's heater.
Background technology
The instant electric water heater has abandoned the huge water tank of storage-type electric water heater, because its volume is little, carries, characteristics easy for installation obtain pursuing of market.All big enterprises are the various products of frequent release in this field.Recently, in the international market, the design concept of popular " small and exquisite Seiko ", it is beautiful, small and exquisite generous that the water heater external form is designed to be fashion, occurred some so-called ultrathin water heaters on the market, and water heater thickness has been reduced to 5-10 centimetre.And people are exploring the method that further reduces thickness.
But no matter how much little volume is for this water heater, and it all must possess temperature control system, heater and corresponding inlet and outlet pipe lines, because heater must possess certain volume, this must limit further dwindling of water heater volume.Simultaneously, owing to be electric heater, the insulation of heater also is very important, in the space that dwindles day by day, under the effect of frequent high temperature, water, how to guarantee that the reliability that insulate is the problem that is worth research equally.
Another aspect, because what water heater was used all is running water, have impurity unavoidably, day vast of heaven is of a specified duration, impurity is deposited in the heater, may stop up the outer wall of delivery port or corrosion heater, therefore needs periodic cleaning, the general employing installed a valve additional at delivery port, can utilize hydraulic pressure that impurity is gone out; But can't accomplish to clean completely.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and a kind of ultrathin instant electric water heater's heater is provided.Heater of the present invention is safe and reliable, thin thickness, and also washable.
The present invention is achieved in that
A kind of ultrathin instant electric water heater's heater, it comprises, the outer case that has the water inlet pipe and water outlet pipe passage, be calandria and be positioned at outer case with the PTC pottery, described PTC pottery is a sheet, it is had the chip electrode clamping that is connected with lead of the same size by its upper and lower surface, and electrode is coated with the Kapton as insulating materials.
Described ultrathin instant electric water heater's heater, described outer case thickness is 1.8-2.2 centimetre.
Described ultrathin instant electric water heater's heater, described outer case comprises that both sides have the forward and backward cover plate of raised line, the front and rear cover plate amalgamation also forms the space that holds calandria, electrode in the middle of linking together by screw, two ends have the end cap up and down that connects with screw, between seal by collision mat.
Described ultrathin instant electric water heater's heater, the height of described PCT potsherd is consistent with the outer case inner height, described collision mat outward in the casing direction surface have the strip projected parts of the fixing chip PCT potsherd that coats by the clamping of chip electrode and by Kapton.
Described ultrathin instant electric water heater's heater, described outer case comprises that both sides and middle part have the forward and backward cover plate of raised line, the front and rear cover plate amalgamation is also linked together by screw, and the described chip PCT potsherd that is coated with Kapton divides for two parts that connected by lead.
The present invention is made into flat casing shape to heater, the PTC pottery that adopts sheet is as heater, therefore be not afraid of scaling, even there is incrustation scale also can not cause heater to damage, and because the characteristics of PTC itself, just no longer rise when temperature reaches curie point 250 and spends, therefore occur the situation of Heating Cup dry combustion method never, security is high.The PTC pottery is by its power supply of chip electrode pair, and electrode coats the polyimide insulative film outward, and excellent insulation performance is safe and reliable, and the complete machine thermal efficiency can reach 96%.Because heater and electrode, insulating barrier all adopt slice structure, integral thickness is about 2cm, and therefore whole water heater thickness can be as small as 3cm, and it is very convenient to carry installation.Simultaneously, outer case is taked demountable structure, the convenient cleaning.
Description of drawings
Below, the present invention is further illustrated in conjunction with the accompanying drawings:
Fig. 1 is an assembling schematic diagram of the present invention;
Fig. 2 is a decomposing schematic representation of the present invention;
Fig. 3 is a most preferred embodiment decomposing schematic representation of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, as a preferred embodiment of the present invention:
A kind of ultrathin instant electric water heater's heater, it comprises, the outer case that has the water inlet pipe and water outlet pipe passage, be calandria and be positioned at outer case with the PTC pottery, described PTC pottery is for sheet and can be divided into small one and large one two, thereby make water heater possess two grades of adjustable power, accordingly, PTC pottery 4,7 is had last chip electrode 5,6 and following chip electrode 3 clampings that are connected with lead of the same size by its upper and lower surface, and all electrodes are coated with the Kapton 2,9 as insulating materials.
Because calandria is set up and is slice structure, therefore, described outer case thickness is 1.8-2.2 centimetre.And final water heater thickness only is about 3cm.
And described outer case comprises that both sides have the forward and backward cover plate 10,1 of raised line; Front and rear cover plate 10,1 amalgamation also forms 3,5,6 the space that holds calandria PCT pottery 4,7 electrodes in the middle of linking together by screw 11, and two ends have the end cap up and down 13,16 that connects with screw 14,17, between seal by collision mat 12,15.
Described ultrathin instant electric water heater's heater, the height of described PCT potsherd 4,5 is consistent with the outer case inner height, and described collision mat 12, the 15 interior direction surface of casing outward has fixing by 3,5,6 clampings of chip electrode and by the strip projected parts of the chip PCT potsherd of Kapton 2,9 coatings.
What Fig. 3 showed is most preferred embodiment of the present invention, described outer case is had the forward and backward cover plate 10,1 of raised line by both sides and middle part, front and rear cover plate 10,1 is put together and is linked together by screw 11, corresponding describedly be coated with Kapton 2 ', 9 ' chip PCT potsherd is divided into two parts 4 ' and 7 ' and runs through the screw 11 of outer case to dodge the centre, PCT potsherd 4 ' and 7 ' respectively by chip electrode 3a 5a and 3b the 5b clamping.
