A kind of mobile air conditioner
Technical field
The present invention relates to a kind of mobile air conditioner.
Background technology
When mobile air conditioner moved under the lower situation of room temperature, existing deicing device was: the bulb that is positioned at the evaporimeter middle part is judged the temperature of evaporimeter, and compressor shutdown when being lower than 0 ℃ is only opened the fan defrost; Compressor just starts restoring running work when being higher than 10 ℃.But if in the median septum residual water is arranged; Will cause icing obstruction of osculum in the median septum; This temperature-sensitive anti-icing equipment can only guarantee to eliminate the frost of evaporimeter; And the ice in the osculum is not had effect, such consequence ice of osculum often is long-pending more thick more, finally freezes base of evaporator and causes damage.
Summary of the invention
The object of the invention aim to provide a kind of simple and reasonable, cost is low, improve evaporimeter service life, the accurate mobile air conditioner of installing and locating, to overcome weak point of the prior art.
A kind of mobile air conditioner by this purpose design comprises the evaporimeter that is arranged on the median septum, and median septum is provided with osculum; Its architectural feature is that the osculum place is provided with deicing device, and deicing device comprises heat conduction member and heater; Heat conduction member one end and heater join, and the other end extends near the osculum; Heater is fixedly installed on the median septum top.
Said median septum is the tank shape, also is provided with the water level switch of control heater switch on it, and the float of water level switch is positioned at median septum.
Said heat conduction member comprises metal buckle, brace and wire netting sheet; The metal buckle is fixedly installed on the downside of heater; The brace upper end buckles in metal card buckles, and lower end and wire netting sheet join; The wire netting sheet is fixedly installed on the median septum, and covers the osculum top.When brace is installed, only need it is sticked in the metal buckle, just can reach fixing effect.
Said metal buckle is provided with more than one; Brace is provided with more than one, and brace is the network structure that is the L type.The width of said metal buckle is buckled so that the netted brace of L type can be clamped on metal card smoothly greater than the width of brace.
Said heater is the PTC electric heater.
The present invention is provided with deicing device through the osculum place at median septum, when avoiding mobile air conditioner under the lower environment of temperature, to freeze, because osculum freezes to stop up, so that the danger freezed of evaporimeter.In addition, through setting up the switch that water level switch comes control heater, reach the purpose of automatic defrosting.It is simple and reasonable, cost is low, improve evaporimeter service life, installing and locating is accurate.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 1-Fig. 6, this mobile air conditioner comprises the evaporimeter 1 that is arranged on the median septum 3, and median septum 3 is provided with osculum 9.Osculum 9 places are provided with deicing device, and deicing device comprises heat conduction member and heater 2; Heat conduction member one end and heater 2 join, and the other end extends near the osculum 9; Heater 2 is fixedly installed on median septum 3 tops.Above-mentioned heater 2 is the PTC electric heater.
Median septum 3 is the tank shape, also is provided with the water level switch 5 of control heater 2 switches on it, and the float 4 of water level switch 5 is positioned at median septum 3.Water level switch 5 is fixed on the median septum 3 through screw.
Heat conduction member comprises metal buckle 6, brace 7 and wire netting sheet 8; Metal buckle 6 is fixedly installed on the downside of heater 2 through screw; Brace 7 upper ends buckle on metal buckle 6, and lower end and wire netting sheet 8 join; Wire netting sheet 8 is fixedly installed on the median septum 3 through screw, and covers osculum 9 tops.Metal buckle 6 is provided with three; Brace 7 is provided with three, and brace 7 is for being the network structure of L type.The width of metal buckle 6 is greater than the width of brace 7.
Its operation principle is: when when refrigeration operating mode cross low and occur that evaporimeter 1 bottom freezes and when stopping up osculum 9, the water that produces during evaporimeter 1 refrigeration can come together in the median septum 3, cause that water levels go up gradually in the median septum 3; The float 4 that drives in the water level switch 5 rises; Touch water level switch 5 when float 4 rises to certain altitude, then heater 4 (PTC electric heater) starts the generation heat, and heat passes to wire netting sheet 8 from heater 4 through metal buckle 6, brace 6 (the netted brace of L type); Make the ice-out that is attached on the osculum 9; After osculum 9 was unobstructed, water levels descended in the median septum 3, and water level switch 5 is closed when waiting water level to be low to moderate certain altitude; Heater 2 cuts out, and melts the effect that osculum freezes thereby reach.
