Abstract
The invention discloses a water heater, which comprises a liner, a heat source, a water inlet, a water outlet, a heat-insulating layer and a plastic film layer, wherein the liner is used for containing a certain quantity of water which can be heated, the heat source is used for heating the water in the liner, the water inlet and the water outlet are communicated with the liner to transfer the water flowing into the liner and flowing out of the liner, the heat-insulating layer is coated outside the liner, and the plastic film layer is coated outside the heat-insulating layer. The plastic film layer is the outermost layer of the water heater. Because the plastic film layer is adopted as the outermost layer of the water heater, the water heater has good electrical-insulating performance, and further, dangers caused by the electrification of a shell are avoided; and in addition, because a metal or plastic shell is omitted, the production and manufacturing cost of the water heater is greatly lowered.
Description
Technical field
The present invention relates to a kind of water heater, relate in particular to the layer structure of water heater.
Background technology
Existing water heater generally includes metal inner tube, is arranged on the electric heating tube in the inner bag, and coats metal shell outside the tank.Because water heater in use all can be connected with power supply usually, so that security performance just seems for water heater is particularly important.Usually the inner bag of water heater and shell all can be through ground wire grounded, in case inner bag or outer casing electrification like this because and the ground wire connection, so can be in lower electromotive force, to guarantee the normal water of user.Certainly; If owing to reasons such as ground wire wrong have caused ground wire electrification; Also adopted the design of water resistance in the existing water heater, promptly prolonged the resistance value of flow path with increase water, thereby even inner bag is charged; Through the step-down of water resistance, make water that last outflow water pipe is used with electromotive force lower and be in the safe scope.Yet, though the user can not get an electric shock because inner bag is charged because this moment, metal shell was also charged, so, if the user runs into because of carelessness, still can cause getting an electric shock, cause security incident.In the existing design, also there is the plastic casing of employing to come the substituted metal shell to avoid the generation of above-mentioned situation.Yet this plastic casing moulding is got up cumbersome, and manufacturing cost is also very high.In view of this, be necessary existing water heater is improved to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of water heater, it has improved outer design, can effectively prevent outer casing electrification, reduces manufacturing cost simultaneously.
Be the realization above-mentioned purpose, a kind of water heater of the present invention, it comprises:
Inner bag is used to accommodate a certain amount of heated water;
Thermal source is used to heat the water in the inner bag;
Water inlet and delivery port and said inner bag are communicated with the water that flows into inner bag and outflow inner bag to transmit;
Thermal insulation layer is coated on outside the said inner bag;
Plastic film layers is coated on outside the said thermal insulation layer, and it is the outermost layer of water heater.
As further improvement of the present invention, also be covered with metal coating on the inner surface of said plastic film layers.
As further improvement of the present invention, said metal coating is a silver coating.
As further improvement of the present invention, also be printed with literal or pattern on the outer surface of said plastic film layers.
As further improvement of the present invention, the monnolithic case of said plastic film layers is confirmed in advance.
As further improvement of the present invention, the integral body of said plastic film layers roughly is a bag shape, and said thermal insulation layer is filled in the said bag shape plastic film layers.
As further improvement of the present invention, said thermal insulation layer forms after by the foamed material condensation.
As further improvement of the present invention, said plastic film layers is processed by polyester material.
Compared with prior art, the invention has the beneficial effects as follows: because the outermost layer of water heater has adopted plastic film layers, its have excellent electric insulating can, thereby avoided the danger that causes because of outer casing electrification; In addition, owing to omitted metal or plastic casing, greatly reduce the manufacturing cost of water heater.
Description of drawings
Fig. 1 is vertical cross-sectional schematic of water heater one specific embodiment of the present invention.
The specific embodiment
Shown in Figure 1 for a specific embodiment of water heater of the present invention.This water heater 100 comprises and is used to store the inner bag 10 that is heated water and is coated on the thermal insulation layer 50 outside the inner bag 10.Inner bag 10 roughly is round barrel shape, and it has drum shape bucket wall, is processed by ferrous metal usually, like steel, iron etc.Thermal insulation layer 50 forms after by foamed material (as being processed by polyurethane material) condensation.Water heater 100 also includes the thermal source that is used to heat cold water, and it can adopt various ways.With the electric heater shown in Fig. 1 is example; Can ring flange 32 be set at a vertical end place of inner bag 1; One electric heating tube 31 is installed on the ring flange and extends into and is stored in the inner water of inner bag; This heating tube can comprise that one has the resistance wire of high impedance, and the positive and negative electrode terminal of this resistance wire is arranged on the ring flange and with the AC power of 220V or 110V and is connected.Certainly, for other forms of water heater,, can come the liquid in the inner bag is heated through the combustion chamber that is provided with outside the tank like gas water heater.The bottom of inner bag 10 is provided with and is used for cold water is introduced the water inlet 21 in the inner bag and is used to discharge a delivery port 22 that is heated water.Usually also be provided with hanger assembly (not shown) on the skin of water heater 100, be used for and the support member (not shown) that is arranged on the body of wall cooperates so that water heater is suspended to body of wall.
In this embodiment, the outermost layer of water heater 100 is a plastic film layers 40.This plastic film layers 40 can that is to say that the integral body of plastic film layers can constitute one bag of shape for the part of plastic film bag.Plastic film layers can be processed by polyester material, as PETG (Polythyleneterephthalate, PET).When making assembling, the mould through foamed material with plastic film layers be looped around inner bag 10 cylindrical shells around, and take this to make the monnolithic case of plastic film layers 40 to be confirmed in advance, like cylindrical shape, cuboid etc.Subsequently, foamed material injected be formed in the cavity between plastic film layers 40 and inner bag 10 cylindrical shells, treat the foamed material condensation after, promptly formed thermal insulation layer 50.In order further to improve heat-proof quality, can apply metal coating at the inner surface of plastic film layers 40, like silver coating.Like this, on the one hand avoided heat conducting generation, on the other hand, reflected back, thereby further reduced the loss of the energy through the heat radiation of metal coating with inner bag through thermal insulation layer.In addition, as the outermost layer of water heater, the outer surface of plastic film layers 40 can also be printed with words identification or decorative pattern.
Because the outermost layer of water heater has adopted plastic film layers, its have excellent electric insulating can, thereby avoided the danger that causes because of outer casing electrification; In addition, owing to omitted metal or plastic casing, greatly reduce the manufacturing cost of water heater.
