Description
Technical field
The present invention relates to a kind of air conditioner room unit, more particularly to a kind of Separated wall type using combustible refrigerant are empty
Adjust air conditioner indoor machine.
Background technology
In the separated hung indoor unit of air conditioner of routine, generally there are a front cover, a heat exchanger, a filtering
Net, a rectangle back casing, the axial-flow fan in the horizontal direction in back casing, air outlet sweep air blade, wind blade,
Air channel and drip tray and electric controling part etc..The refrigerant import and export of the heat exchanger of air conditioner room unit is often in factory
One section of 300-500mm length, the short tube of other end band connection mouth is just respectively welded, when air conditioner is installed, to pass through connecting tube
Road (current standard configuration is grown for 3m) one end is connected with one end of band connection mouth on indoor set heat exchanger weld nipple, connects
The other end of pipe is connected with the connector of outdoor unit, and such indoor set and outdoor unit just connect into one by connecting pipe and closed
Formula loop, so as to form refrigerant circulation loop, refrigeration, the heat-production functions of air conditioner are realized, due to the peace of detachable air conditioner
Dress is directly carried out in user family, therefore, often using quick when air conditioner room unit weld nipple is connected with connecting pipe
Joint connects or using the connection of horn mouth connected mode, these connected modes all exist connection loosely, horn mouth breakage etc. can
The situation that refrigerant can be caused to be leaked in junction occurs, when air conditioner refrigerant is not using non-ignitable, quick-fried, nontoxic, tasteless
Refrigerant such as R22, R410a, R134a etc. when, the leakage of indoor set connecting portion will not bring danger, but work as air conditioner system
When cryogen is using combustible refrigerant such as R290, R32 etc., the leakage of indoor set connecting portion has in the presence of having incendiary source
Burning, the generation of fire may be caused；On the other hand, the heat-transfer pipe of indoor set heat exchanger heat exchanging part is wrapped up by fin, but
Both ends are exposed copper pipe, and one end is the elbow part of heat-transfer pipe U-tube, the other end be weld ell with heat exchanger into and out of
The part of mouth weld nipple, these directly exposed copper pipes may produce defect in installation, maintenance due to collision, and then lead
Leakage is caused, the welding position of weld ell may also cause to leak due to the defects of welding quality, it is also possible to due to using process
In corrosion cause to leak.But when these leakages occur, the combustible refrigerant leaked can be by various passages, slot leakage
Into the room of installation indoor set, cause the leakage path for not knowing that combustible refrigerant is actual, it is impossible to control it, enter
And cause the presence of burning risk.Therefore conventional separated hung indoor unit of air conditioner is existed tight when using combustible refrigerant
The security risk of weight, it is impossible to directly using combustible refrigerant as air conditioner refrigerant.
The content of the invention
Problem to be solved by this invention is, the shortcomings that overcoming above-mentioned prior art, there is provided one kind can avoid interior
Machine connecting tube joint area occur leakage and can enough indoors the exposed copper tube sections in machine heat exchanger both ends due to a variety of causes occur
The combustible refrigerant of control leakage enters the direction in room from indoor set and enters the size of passage during leakage so that using flammable
The indoor set that the air conditioner room unit of refrigerant is not limited by installation site.
To achieve these goals, the present invention adopts the following technical scheme that：A kind of air conditioner using combustible refrigerant
Indoor set, the air conditioner room unit is surrounded jointly by above shell, back casing and heat exchanger to be formed for installation indoor set internal part
Inner chamber, it is characterised in that：
The sky in the inner chamber space as electric control box part, Welding of Heat-exchanger elbow and inlet/outlet pipe welding portion successively
Between, installation fan section space and heat exchanger U-shaped pipe elbow part space；The company of indoor heat exchanger import and export welding
The connecting pipe for connecing short tube and air conditioner is integrated, and the connection short tube of the indoor heat exchanger import and export welding directly extends
Connecting pipe as air conditioner simultaneously；It is indoor for installation after the above shell and the back casing and heat exchanger install
The space of three parts of the inner chamber of the internal part of machine communicates, and by above shell and the contact site at heat exchanger both ends
Form sealing state so that for the Welding of Heat-exchanger elbow and inlet/outlet pipe welding portion of the inner chamber of the internal part of installation indoor set
Space and the space of heat exchanger U-shaped pipe elbow part sealed off with outside, to control leakage of refrigerant to spread.
The connection short tube and connecting pipe (the current standard of air conditioner that the present invention welds indoor heat exchanger import and export
It is configured to 3m length) be integrated, that is, cancel the connecting pipe of present standard configuration length (3m), by indoor heat exchanger import and export
The connection short tube of welding, which directly extends, (such as 3m, gets well and checks and regulates together in factory process, cased together with indoor set.So on the one hand
Do not increase the manufacture burden of factory, reduce the connecting link of an indoor set and connecting pipe in installation process again, more
It is important that it completely avoid indoor set and the risk of connecting pipe junction leakage.Shell, rear shell before air conditioner room unit
Body surrounds the inner chamber of the internal part for installation indoor set with heat exchanger jointly, and the inner chamber is need to be mounted so that blower fan and its electricity
Machine, the sky of four segment spaces, the i.e. space of installation fan section, Welding of Heat-exchanger elbow and inlet/outlet pipe welding portion can be divided into
Between, the space of the space of heat exchanger U-shaped pipe elbow part and electric control box part；Above shell and the back casing with
And after heat exchanger installs, the space of three parts of the inner chamber of the internal part for installing indoor set communicates, Er Qieyou
Above shell and the contact site at heat exchanger both ends necessarily be formed sealing state so that for the inner chamber of the internal part of installation indoor set
The space of Welding of Heat-exchanger elbow and inlet/outlet pipe welding portion and the space of heat exchanger U-shaped pipe elbow part sealed with outside
Isolation.So either Welding of Heat-exchanger elbow and inlet/outlet pipe welding position or heat exchanger U-shaped pipe bend part leak,
Refrigerant will diffuse to the inner chamber of whole indoor set, without expanding from the contact site at preceding face-piece Yu heat exchanger both ends to outside
Dissipate, so as to play a part of controlling leakage of refrigerant diffusion.
The present invention can use following any one or several improved technical schemes:
Electric control box part is independent, not defeated with evaporator with fan electromotor individually in a separate space
Enter output precision and be in same space, during so as to avoid evaporator elbow or evaporator in-out box from leaking,
The combustible refrigerant of leakage contacts with electric component.
The heat exchanger import and export welded pipe of described air conditioner room unit from back casing draw when, using the sealing of rubber
Material is sealed so that Welding of Heat-exchanger elbow and inlet/outlet pipe coupling part for the inner chamber of the internal part of installation indoor set
Space sealed off with outside.Thus prevent that refrigerant passes through connecting tube from the inner chamber of indoor set when indoor set from leaking
Spread to outside in gap between shell below.
Wind blade should have side or both sides to leave certain gap, thus make when shutting down closing with above shell
Obtaining refrigerant when indoor set leaks can be empty to external diffusion, diffusion by wind blade and gap above long and narrow between shell
Between it is big, advantageously reduce the concentration of refrigerant diffusion.
