Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, according to an embodiment of the invention, water tank includes liner 3, shell 4 and electrical appliance kit, the setting of liner 3 exists
In shell 4, and there is foaming agent gap 5 between shell 4, electrical appliance kit is located in foaming agent gap 5, and electrical appliance kit includes insulating layer
Structure 8 and holding shell 9, insulation layer structure 8 are fixedly connected on liner 3, and holding shell 9 is arranged in insulation layer structure 8.
The electrical appliance kit of the water tank includes insulation layer structure 8, holding shell 9, including holding shell 9 is arranged by insulation layer structure 8
On courage 3, the insulation between holding shell 9 and liner 3 may be implemented in insulation layer structure 8, the electric elements hair in this way in electrical appliance kit
When raw electric leakage, leak conductance can be prevented to liner 3, prevent the foaming agent that ignites, ensure user security, avoid danger proliferation.
Preferably, electrical appliance kit further includes box cover 7, and box cover 7 is connected on shell 4, and is arranged corresponding to holding shell 9, is accommodated
There is gap between shell 9 and shell 4.Electric elements can be isolated in box cover 7 and holding shell 9, when due to striking sparks inside
When fire or water tank external cause are on fire, leak conductance can be prevented to shell 4 and/or liner 3, or prevent from igniting
Foaming agent ensures user security, avoids danger proliferation.
As shown in Figure 1, in the present embodiment, the shell 4 of water tank is used to protect each structure of water tank, for example, liner, electricity
Device box etc..Shell 4 can be stainless steel, and the performance that the shell 4 of this material is durable and wear-resisting is relatively good, can effectively carry
Rise the service life of water tank.Liner 3 can be the liner of carbon steel material.It can be in foaming agent gap between liner 3 and shell 4
Filling-foam dosage form avoids heat from distributing at foaming layer to be kept the temperature, and saves the energy.The material of foaming layer can be poly- ammonia
Ester thermal insulation foaming layer.According to the difference of heat preservation demand, the thickness of foaming layer can be selected suitably, for example, in the present embodiment, hair
The thickness of alveolar layer is 45mm.
In order to enable foaming agent easily to inject, to form foaming layer, the top setting of shell 4 in foaming agent gap
There is the blowing agent injection port 10 for foaming agent injection foaming agent gap 5.Foaming agent is reserved at the top of water tank stainless steel casing
Inlet 10.
In the present embodiment, in order to carry out effective position and support so that it can be firmly placed in shell 4 to liner 3,
Water tank further includes the first injection molding supporting rack 11, and the first injection molding supporting rack 11 is arranged at the top of liner 3, and is supported on 4 He of shell
Between liner 3.
Optionally, in order to further enhance the structural stability of water tank entirety, water tank further includes the second injection molding supporting rack 12,
Second injection molding supporting rack 12 is arranged in the bottom of shell 4, and is supported between shell 4 and liner 3.Second injection molding 12 He of supporting rack
First injection molding supporting rack 11 coordinates, and can form reliable and stable support to liner 3.
Pass through between the top and the top of liner 3 of the shell 4 in the water tank and bottom of the shell 4 of water tank and liner 3
Bottom between using moulding holder (i.e. first injection molding supporting rack 11 and second injection molding supporting rack 12) be supported isolation, make
Liner 3 is obtained more to stablize.
In such cases, for water tank when producing assembly, side and the bottom plate of shell 4 shift to an earlier date soldering, wait for that liner 3 assembles
After in shell 4, the stainless steel top cover of the shell of water tank carries out soldering again with the side of shell 4, to facilitate inside shell 4
The assembly of part.
In the present embodiment, electrical appliance kit is double layer material structure design, the use of outer layer is that insulation layer structure 8 (is for example, noted
Plastic) holding shell 9 (being, for example, sheet metal box body) is embedded, so that holding shell 9 is isolated with liner 3, the electric appliances member such as electric heating tube, temperature limiter
Part is fixed on the metal plate holder in holding shell 9, is installed and is fixed to realize.
Optionally, in the present embodiment, insulation layer structure 8 can be moulding structure.Holding shell 9 can be metal plate shell
Body.It on the one hand can ensure insulation effect in this way, and can ensure the structural strength of electrical appliance kit.
Optionally, box cover 7 towards holding shell 9 is covered with empire cloth on one side.Specifically for example, being pasted in box cover 7 thick
The high pressure resistant insulation cloth of at least 3mm is spent, box cover 7 can be directly anchored to using screw on shell 4, to be isolated with holding shell 9.
The empire cloth can cover the part surface of box cover 7, can also cover all surfaces of box cover 7.
Optionally, in order to realize effectively sealing and protect, box cover 7 covers holding shell by being connect with insulation layer structure 8
9。
Optionally, there is safety clearance between box cover 7 and holding shell 9.Box cover 7 can be ensured to reach in this way for electric appliance
The purpose of box sealing function, and can prevent from causing on leak conductance to shell 4 when there is electric leakage in holding shell 9.
Optionally, the value range of safety clearance is more than or equal to 4mm.Certainly, difference as the case may be, safety
The size in gap can determine according to demand.
For the ease of inlet-outlet line, the lower edge centre bit of box cover 7 is equipped with 1 groove, can be used for coordinating and position, and
1 outlet hole is reserved between shell, is used for cabling.
The electrical appliance kit of the water tank and the shell 4 of water tank are hermetically sealed isolation structure, and at top, blowing agent injection port 10 is filled with
Gaps all between liner 3 and shell 4 can be filled after foaming agent, inside water tank foaming agent by the holding shell 9 of sheet metal component completely every
Leave, even if thus there is a situation where in electrical appliance kit forceful electric power terminal lead loosen, it is exhausted also to embed high pressure because of the box cover 7 of electrical appliance kit
The isolated insulation of the insulation layer structure 8 of edge cloth and the moulding outside holding shell 9 acts on, and without being transmitted to tank shell 4, keeps away
Exempt from people and touches the danger that shell gets an electric shock.
According to another aspect of the present invention, a kind of water heater is provided comprising above-mentioned water tank.The water tank of the water heater,
Electric elements are installed using the holding shell 9 of sheet metal component structure, realize that water tank foaming agent is fire-retardant, mesh of charging member isolated insulation
, so that water heater is installed and used indoors, can prevent fires protection against electric shock, promote the safety and reliability of water heater.
It water tank according to the present invention and is had the following technical effect that with its water heater：
Inner water tank is designed with shell integral seal structure, and integral-filled foaming layer in foaming agent gap prevents foaming layer
It is exposed to be easily ignited；
Inner water tank and electrical appliance kit are dielectrically separated from processing, avoid because touching water tank when refrigerant pipe and electric heating tube leak electricity
Danger Electric shock risk；
It is designed by water tank safeguard construction, isolation inflammable thing play the role of fire safety, and protection against electric shock is played in electrical appliance kit insulation.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
