Abstract

The utility model relates to a control device of an air moisture remover, comprising a hair hygrometer, a relay and a direct current power supply. The metallic surface of the hair hygrometer is provided with two metal rods insulated with the metallic surface. The two leading wire ends of a control circuit composed of the relay and the direct current power supply are respectively connected with the two metal rods. One end of the pointer of the hair hygrometer is connected with the positive electrode of the direct current power supply. The other two leading wire ends of the control circuit are respectively connected with the input terminals of city power. The device can enable a moisture remover to control the air humidity in the control room automatically and avoids disadvantages of randomness of manual humidity control caused by artificially starting or shutting the moisture remover.

Description

Controlling device of air moisture remover

The utility model relates to a kind of air dehumidifier control device, is particularly suitable for the automatic controlled humidity of air dehumidifier and uses.

It all is to decide according to the humidity that hygrometer shows that air dehumidifier is started shooting with shutdown, but has no association in their work, i.e. the humidity of hygrometer demonstration can not directly start or stop dehumidifier work, and the start shutdown all needs manually-operated, and trouble seems.If can use the device of forming by hygrometer and control circuit directly to control dehumidifier work, then can remove manually-operated from, not only saved time but also can avoid the randomness of Artificial Control humidity.But still there is not this device so far.

The purpose of this utility model aims to provide a kind of air dehumidifier control device, uses this device, and the function of drying is controlled indoor air humidity automatically.

Fig. 1 is the electrical block diagram of air dehumidifier control device.

Now the utility model is described by Fig. 1.

Among Fig. 1, on behalf of

relay

11,22,33, they and dc source 44, three frame of broken lines form control circuits respectively.Metal bar 12 and 13 with surface insulation is housed on the metal surface of hair hygrograph 4.One end of the coil 3 of relay 33 is connected in metal bar 13, and an end of the coil 2 of the other end and relay 22 is with being connected to dc source 44 negative poles, the metal finger 4 of the positive pole of dc source and hair hygrograph 4 ' an end 14 be connected.Coil 2 other ends are connected in metal bar 12.The normally closed interlock 3 of relay 33 ' binding post 9 and an end of the coil 1 of relay 11 be connected with two inputs of city's power supply respectively.The other end of coil 1 and its normally open contact 1 ' binding post 5 ' be connected to the normally open contact 2 of relay 22 ' binding post 8 ', normally open contact 2 ' binding post 8 and normally closed interlock 3 ' binding post 9 ' with the normally open contact 1 that is connected to relay 11 ' binding post 5, the normally open contact 1 of relay 11 ^MWith 1 ^M' binding post 6 ' be connected with two inputs of city's power supply with 7 ' respectively, and normally open contact 1 ^MWith 1 ^M' binding post 6 be connected with the power input of dehumidifier 10 respectively with 7.

This device can make dehumidifier control indoor air humidity automatically, avoids artificially dehumidifier being started shooting or being shut down, and causes the random shortcoming of Artificial Control humidity.

Now in conjunction with Fig. 1 this device operation principle is described in detail again.

Among Fig. 1, suppose that metal bar 12 scales of living in represent the maximal humidity that is limited, metal bar 13 scales of living in are minimum humidity.Pointer 4 ' all do not contact with 13 with metal bar 12, whole device is not worked.

Suppose that humidity constantly increases, pointer 4 ' progressively move to metal bar 12, when they contacted, then the loop of Xing Chenging was: the positive pole → pointer 4 of dc source 44 ' the negative pole of an end 14 → metal bar 12 → coil 2 → power supply 44.At this moment, coil 2 energisings, normally open contact 2 ' closure.The loop that forms is: city's power supply one input → normally closed interlock 3 ' → contact 2 ' → coil 1 → city another input of power supply.At this moment, because of coil 1 energising, so normally open contact 1 ', 1 ^M, 1 ^M' all closed, then by 1 ^M, 1 ^M' closure makes dehumidifier 10 work.And normally open contact 1 ' closure (although normally open contact 2 ' disconnection) then still can form the loop: city's power supply one input → normally closed interlock 3 ' → normally open contact 1 ' → coil 1 → city another input of power supply.Therefore if coil 1 switch on always, normally open contact 1 ', 1 ^M, 1 ^M' just closed always and pointer 4 ' leave metal bar 12 had nothing to do when not contacting with metal bar 13 again.So when dehumidifier 10 after work a period of times, humidity descends, when pointer 4 ' leave metal bar 12 did not contact with metal bar 13 again, dehumidifier still worked on.

Pointer 4 ' when contacting with metal bar 13, the loop of formation is when humidity drops to: the positive pole → pointer 4 of dc source 44 ' an end 14 → metal bar 13 → coil 3 → negative pole.At this moment, coil 3 energisings, normally closed interlock 3 ' disconnection, relay 11 quits work, and cuts off the input power supply of dehumidifier 10.

When humidity raises, pointer 4 ' leave metal bar 13, coil 3 no powers, so normally closed interlock 3 ' recovery is normally closed.Like this, this device cooperates dehumidifier 10 work, and controlled humidity goes round and begins again automatically.

Fig. 2 is the front appearance structural representation of air dehumidifier control device.

Among Fig. 2,4 is hair hygrograph; 4 ' be metal finger; 12 and 13 is metal bar; 14 is metal finger 4 ' one ends; 11,22,33 is relay; 44 is dc source; 15 is shell bottom plate.

Metal bar 12 and 13 and the contact position of the metal surface of hair hygrograph 4 can put plastic tube and make they and surface insulation.
