Conflicting or will be understood that the combination of this technical scheme is not present when cannot realize, also not in the protection model of application claims
Within enclosing.
The present invention proposes a kind of electric expansion valve, air-conditioner outdoor unit and air-conditioning.
In embodiments of the present invention, see figures.1.and.2, the electric expansion valve includes valve body 100, is located on valve body 100
Coil 200, one end of valve body 100 are provided with pin 110；Electric expansion valve also includes protective cover 300, and protective cover 300 has to be opened
Mouth 301, the one end of protective cover 300 by opening 301 from valve body 100 away from pin 110 is located on valve body 100 and coil 200.
When specifically, on the equipment such as electric expansion valve machine installed outdoors, its pin 110 is typically toward lower section, when online
After protective cover 300 is arranged with circle 200 and valve body 100, it is possible to stop that rainwater drenches coil 200 and valve body 100, thus, keeping away
The problem that coil 200 and valve body 100 get rusty is exempted from, it is ensured that the reliability service of electric expansion valve.
Protective cover 300 is being provided with opening 301 on 110 one end of pin of valve body 100, is easy to protective cover 300 available
Opening 301, itself direction from top to down is set on coil 200, accelerates installation rate, also, opening 301 can also enter
One step guarantees that electric expansion valve fully can radiate, it is to avoid electric expansion valve is damaged because overheated.Wherein, the thickness of protective cover 300
May be configured as 1mm or more than 1mm so as to enough intensity, it is not easy to be worn.Wherein, protective cover 300 adopts rubber
Or PVC material is made, make anti-skid cover 300 that there is stronger waterproof and antiseptical function.
Mount and dismount for convenience, it is preferable that protective cover 300 in sleeve-shaped arrange, the radial section of protective cover 300 with
The shape adaptation of the radial section of 200 outline of coil.That is the shape of the radial section of protective cover 300 and 200 outline of coil
Radial section shape consistent or slightly poor a little, after can so allowing protective cover 300 to be enclosed within coil 200, protective cover 300 and coil
200 more close fits are in one.
Technical solution of the present invention is by being set on valve body 100 and coil 200 using protective cover 300, it is possible to stop rain
Water drenches valve body 100 and coil 200, thus, avoiding valve body 100 and coil 200 gets rusty, it is ensured that the reliability of electric expansion valve
Running.In addition 110 one end of pin of valve body 100 is provided with opening 301 in protective cover 300, opening contribute to radiating and
It is easy to protective cover 300 to be set on valve body 100 and coil 200.
The concrete shape of above-mentioned protective cover 300 is not limited, and in a preferred embodiment, with reference to Fig. 3, protective cover 300 includes
Roof 310 and the annular sidewall 320 extended by four circumferential one sides of roof 310；Annular sidewall 320 away from roof 310
One end forms opening 301.Thus, protective cover 300 is formed with the tubular structure that roof 310 and annular sidewall 320 are formed, and tubular
The opening of structure is exactly the opening 301 of the present embodiment.Wherein, roof 310 can in plane, or its in the middle part of to keeping away
The direction projection of mouth 301, the present embodiment preferably adopt latter scheme, i.e., the middle part of roof 310 is to the direction away from opening 301
Projection, as the outer surface of roof 310 is not plane, thus, the outer surface for avoiding rainwater in roof 310 is stopped.
In the embodiment, further, the outer surface of roof 310 is arranged in inclined-plane along its edge to its medium position, such as
This can allow flow velocity of the rainwater on the outer surface of roof 310 faster.
Specifically, the outer surface of roof 310 includes plane 310a and multiple connection planes 310a and the ring positioned at middle part
The inclined-plane 310b of shape side wall 320.That is, the longitudinal section shape of roof 310 is trapezoid.Thus, rainwater drops to protective cover 300
310 outer surface of roof when, rainwater can be accelerated from plane 310a to the order of inclined-plane 310b so as to drop on ground
Flow velocity, so that reduce the time of contact of rainwater and protective cover 300.Wherein, plane 310a can conveniently arrange model coding.
In another embodiment, the outer surface of roof 310 can also by its any point towards annular sidewall 320 in dipping down
Tiltedly, i.e. the longitudinal section shape of roof 310 is arbitrary triangle.
In another embodiment, the outer surface of roof 310 can be in also to dip down by its side court side relative with the side
Tiltedly, i.e. the cross sectional shape of the roof 310 of protective cover 300 is right angled triangle.
Further, see figures.1.and.2, one end interval setting of roof 310 and valve body 100 away from pin 110.So
Arrange, i.e. the roof 310 of protective cover 300 has certain space with valve body 100 away from one end of pin 110, tears open in protective cover 300
When unloading, it is possible to use by grabbing the roof 310 of steady protective cover 300, the slightly deformation of roof 310 of protective cover 300 allows the user can be more
Protective cover 300 of easily taking is dismantled.
Further, with reference to Fig. 3, the outer surface of roof 310 is provided with model coding (not shown).So, it is easier to allow use
The protective cover 300 of various models is distinguished at family, and is correctly applied in corresponding electric expansion valve, it is to avoid inappropriate protective cover
300 during assembling electric expansion valve, the problems such as causing dress to unmatch, assemble not tight.
The present invention also proposes a kind of air-conditioner outdoor unit, and the air-conditioner outdoor unit includes the electric expansion valve, the electronic expansion
Concrete structure reference above-described embodiment of valve, as this air-conditioner outdoor unit employs whole technical sides of above-mentioned all embodiments
Case, all beneficial effects that therefore at least there is the technical scheme of above-described embodiment to be brought, this is no longer going to repeat them.
The present invention also proposes a kind of air-conditioning, including the air-conditioner outdoor unit；The air-conditioner outdoor unit includes that the electronics is swollen
Swollen valve, concrete structure reference above-described embodiment of the electric expansion valve, as this air-conditioning employs the complete of above-mentioned all embodiments
Portion's technical scheme, all beneficial effects that therefore at least there is the technical scheme of above-described embodiment to be brought, here is no longer one by one
Repeat.
The preferred embodiments of the present invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, every at this
