Description
Technical field
The present invention relates to household appliance technical field, dehumidifier field, particularly, relate to a kind of dehumidifier sealing electrical appliance kit and be provided with sealing electrical appliance kit.
Background technology
Due to cold-producing mediums such as R22, R134a that existing dehumidifier uses in a large number, there is destruction to atmospheric ozone layer and there are higher greenhouse effects, belong to the cold-producing medium that needs are replaced, and the native compound that some occurring in natures such as R600a (iso-butane), R290 (propane) exist, both atmospheric ozone layer can not be destroyed, do not cause global warming again, belong to environmentally friendly cold-producing medium.These cold-producing mediums are just being begun one's study for the refrigerant dehumidification system such as air-conditioning, dehumidifier for substituting a large amount of R22 used at present.R410A.R134A cold-producing medium.
But R290 belong to flammable can quick-fried type cold-producing medium, to the system using this cold-producing medium, its security has higher requirement.In existing dehumidifier, the electrical equipment such as mainboard, transformer controlling dehumidifier work is placed with electrical appliance kit, the situation that electrical equipment is struck sparks may be had in the event of failure, if use in this air-conditioning system flammable can quick-fried type cold-producing medium R290, once cold-producing medium occurs to reveal and enter electrical appliance kit to gather, may security incident be there is, therefore need to avoid cold-producing medium to assemble in electrical appliance kit, effective easy isolation forceful electric power vigour part.
Summary of the invention
In order to use safely flammable can quick-fried type cold-producing medium (as R290, R32 etc.), in order to improve the security that dehumidifier uses.Forceful electric power part, by having the electric elements seal isolation of electrification spark hazard, is positioned in sealing box body, thus itself and light current part is isolated by the present invention.If now there is a small amount of leakage of refrigerant, also cannot enters sealing electrical appliance kit and assemble, thus eliminate safe hidden trouble, improve security.
The present invention is achieved through the following technical solutions: a kind of sealing electrical appliance kit, it is characterized in that, sealing electrical appliance kit is arranged in electrical appliance kit, comprise: sealing box body, the inner chamber that there is sidewall and surrounded by sidewall, be provided with dividing plate in inner chamber, the lumen segmentation of sealing box body is the first cavity and the second cavity by dividing plate; Seal cover, lid is located on sealing box body and also corresponds to the first cavity, and the corresponding dividing plate of seal cover has the protuberance stretching into the second cavity; Fluid sealant obturator, is arranged in the second cavity, the upper surface of fluid sealant obturator higher than protuberance lower limb and lower than the top edge of dividing plate.
Further, dividing plate has the first threading gap.
Further, protuberance has the second threading gap corresponding with the first threading gap, the upper surface of fluid sealant obturator is higher than the second threading gap.
Further, the sidewall top edge of sealing box body is surrounded with injecting glue groove, injecting glue groove and the second cavity connects, and the bottom surface of injecting glue groove is lower than the top edge of dividing plate.
Further, the top edge of sidewall and seal cover clamping.
Further, sidewall has bayonet socket, and seal cover has grab.
Further, seal cover is provided with the connecting portion be connected with electrical appliance kit.
Further, seal cover is provided with cable position limiting clamp.
Further, slot is provided with in the first cavity of sealing box body.
And a kind of dehumidifier, it has electrical appliance kit, in electrical appliance kit, arranges sealing electrical appliance kit as above.
Pass through technique scheme, major advantage of the present invention is, strong electric elements are placed in sealing electrical appliance kit, cold-producing medium can be intercepted and directly enter this box, when the condenser of dehumidifier, evaporimeter or pipe-line system have small leakage, the cold-producing medium revealed is blocked in outside box, cannot enter in box, thus ensure that security of system.
