Summary of the invention
The objective of the invention is to propose water heater a kind of economy, simple and small and exquisite.
According to the present invention, this purpose is to realize by such water heater, it has a water tank, an electric heater unit and a main function components that is used for the water in the heating water tank, described functional part comprises a water feed apparatus, a discharging device, a control device, a flow switch, display element, executive component, temperature sensor, wherein water tank partly is made up of two water tanks at least, at least water heater has comprised a water feed apparatus, a discharging device, a control device, a flow switch, display element, executive component, the main function components of temperature sensor be installed in the water tank part one of on, it is characterized by, the water tank partial design that functional part has been installed on it becomes bi-component plastics die casting and has the sealing that is used for the functional part that is communicated with water tank cavity.
Partly go up and simplified manufacturing widely by whole functional parts being installed in a water tank because almost all assembly manipulation all on unique parts, carry out.So just can join at an enterprising luggage of assembly line easily, on this assembly line, a water tank is partly by a plurality of assembly stations, respectively functional part is being contained on these assembly stations on this water tank part, and the water tank part that assembling is left on a station of these assembly stations, to be assembled into complete water tank.Preferably whole functional parts all is contained on water tank part, if but at least the main function components of water heater be contained in a water tank when partly going up, also be enough.Main function components for example is that heater, a water feed apparatus, a discharging device, a control device, flow switch, display element, executive component, temperature sensor or other functions to water heater are especially controlled the parts that work.So, on this has installed the assembling water tank part of the whole of water heater or main at least functional part, can in whole manufacturing process, keep central module, other less parts of assembling usually on this central module.
With a kind of when having one section heater that freely stretches into water tank at least, but this heater fixed and arranged is in water tank.Particularly, this heater can be arranged in the water tank like this, and the section of its heating is not contacted with water tank wall, and heater is with regard to available high power density like this, thereby can reach the high power with respect to the water heater physical dimension.In addition, in this case, owing to guaranteed the safe distance of heater to water tank wall, water tank can be made with a kind of non-refractory, economic materials such as plastics.Heater for example can be a kind of tubular heating element.Can reduce the manufacturing cost of water heater like this and reduce its physical dimension.
Water tank preferably has the fixture that water heater is installed.Fixture also can only be arranged on the water tank part.Fixture refers to be used for water heater is installed to device on the wall, for example hole of break-through screw or bolt especially.
In addition, the rear wall that water tank part can be designed to the part, particularly water heater of the casing of water heater can partly be made of a water tank, and water tank can partly be made of two water tanks.For this reason, the water tank part can have the planar extension that constitutes shell at least a portion.A water tank of using as the rear wall of water heater partly has the erecting device of water heater.
In order to constitute the shell of water heater, a water tank especially water tank part can have the independent fixture of fixing an end cap, so just can reach with very little cost an end cap is installed.This device can be a padlock.Particularly, cover can constitute the antetheca of water heater.If water tank partial design precedent such as rear wall shell one section and with the fixture of an end cap, then after the repertoire parts are assembled on the water tank, only need end cap carried and buckle into the shell that can improve water tank.
Partly use bi-component plastics die casting if at least one water tank of functional part has been installed, then can further simplify assembling.In this case, stretch into functional part in the water tank or that be communicated with water tank cavity when making corresponding water tank part with regard to molded on correct position, so do not need to embed the additional process of sealing.For this reason, as a kind of component useful elastomers.Particularly, these sealings can be used for stretching into the heater in the water tank or are used to be connected safe excess pressure valve on the water tank.Mode according to this, the also barrier film of moulding gauge tap function for example, i.e. cavity of moulding or at least one groove in a water tank part are then with barrier film that extends on this groove of elastic component moulding.
