Abstract
The utility model discloses a non-contact point water-level control mechanism for de-humidifier, a sensing part is arranged at the other end of a lever with a floater, a sensing tube which is corresponding to the sensing part is arranged on tank body, when water level in the water tank rises to the preset value, the magnetic field loop of the sensing part excites the sensing tube to emit magnetic sensing signal and actuate electronic switch to function. As both the sensing part and the sensing tube of the non-contact point water-level control mechanism do not directly contact each other, no contact current occurs, therefore the utility model has long life and can reduce mistaken actions and improve the reliability of complete unit, thereby being convenient for the daily use of user.
Description
Technical field
The utility model relates to a kind of dehumidifier, particularly relates to a kind of contactless level controling mechanism.
Background technology
Dehumidifier enlarges day by day in the application of aspects such as industrial and agricultural production, national defense industry and numerous residents' living environment, is accepted by people more and more.The action principle of dehumidifier is by refrigeration system, and air moisture in the surrounding environment is sucked in the dehumidifier, through the effect of condenser, evaporator, the airborne moisture content globule that congeals into, flows into water tank, reaches the purpose that surrounding air dehumidifies.The cistern water level control of prior art dehumidifier, all adopt: when the water level in the water tank rose, the float in the water tank drove rod member and rises, and drove microswitch contact conducting when reaching setting value, directly controlled major loop.Disclose dehumidifier and microswitch control cistern water level technology as Chinese patent " a kind of semiconductor refrigerating dehumidifier " (patent No. 97206455).It is provided with one and can makes condensate water compile the back to flow into fair water fin in the diversion trench, on described water storage tank, be provided with the microswitch of this dehumidifier braking of a may command and starting in the middle of condenser and water storage tank.Because the control of the cistern water level of prior art is after rising by float in the water tank, to touch microswitch, directly controls major loop.Therefore, switch contact is scaling loss very easily, and serviceable life is short, and corresponding misoperation also increases thereupon, or does not restart after spill-over or the water removing; Simultaneously,, the precision of water tank processing and water tank riding position has been proposed higher requirement, also increased the possibility of misoperation because the microswitch amount of movement is little.
Summary of the invention
The utility model mainly is that existing water tank for dehumidification machine water level control reliability owes high in the solution prior art, and structure is comparatively complicated, and manufacturing cost is higher, deficiencies such as operation inconvenience.
In order to solve the problems of the technologies described above, agent technology scheme of the present utility model is: described trigger mechanism is the contactless inductive trigger mechanism; The other end of rod member of band float is provided with induction pieces, with the opposite position of induction pieces, induction tube is installed on the casing.
Described induction pieces is a magnetic material, and described induction tube is a tongue tube.
The xsect of described rod member is a cruciform, and the orienting sleeve that adapts with rod member size, shape is arranged on the water tank.Described rod member can be passed through in this orienting sleeve, only does vertical movement up and down, solved preferably existing rod member easily about or front and back rock, cause locating uncertain problem; Its rod member xsect can also be circle, square or rectangle etc.
In addition, described contactless inductive trigger mechanism can also be sensing trigger mechanisms such as photo-electric, piezoelectric type or condenser type.
Described induction tube, induction pieces are light activated element in photo-electric sensing trigger mechanism, are capacitive reactive element in the capacitive sensing trigger mechanism, are piezoelectric element in piezoelectric type sensing trigger mechanism.
Above-mentioned contactless level controling mechanism, because induction pieces does not directly contact with induction tube, contactless electric current, so long service life, significantly reduced the above-mentioned thereby misoperation that produce former, improved the reliability of complete machine, simultaneously because the positioning accuracy request of trigger mechanism is low because of pitting of contacts etc., reduce manufacturing cost, also made things convenient for daily use.

Embodiment
Embodiment: extremely shown in Figure 4 as Fig. 2, being fixed with xsect on its float 5 is criss-cross rod member 3, and the orienting sleeve 1 of rod member 3 on water tank 4 passes through water tank 4, and its orienting sleeve internal diameter and shape and rod member adapt, because placing restrictions on of orienting sleeve 1 makes rod member 3 only can do vertical movement up and down; The induction pieces 2 that install rod member 3 upper ends is a permeability magnetic material, and it can be permanent magnet or soft iron, and the induction tube of installing with induction pieces 2 corresponding positions on casing 6 is a tongue tube.Float 5 floats along with the variation of water level in the water tank 4, thereby changing the distance between induction pieces 2 and the induction tube 6, when both distances reach setting value, the magnetic field boundary loop excitation induction tube 6 that induction pieces 2 forms sends the magnetic induction signal, by signal enlarger and topworks, the action of triggering electronic switch shuts down dehumidifier, sends alerting signal; After the water of water tank 4 was removed, float descended, and dehumidifier is reset.
Fig. 4, Fig. 5 have showed the utility model in addition two kinds of liquid level follower-float-ball types and turnover plate type embodiment synoptic diagram respectively, and 7 is the location fulcrum of rod member 3 among the figure.
