Abstract
The invention discloses an improved draining pump on-off control mechanism of float switch, which is characterized by the following: detecting the water level variation of condensed water through high precise pressure-sensitive resistance in the water containing disk; providing control signal to drainage pump through PCB to control switch the water pump accurately. The invention avoids the problem of discharging the condensed water in time due to float ill reaction, which reduces the ineffective working time and improves the product reputation and competitive power.
Description
Technical field
The present invention relates to the controlling organization of air conditioner condensate water draining pump, particularly relate to the air conditioner condensate water opening/closing control mechanism for drainage pump that utilizes piezo-resistance.
Background technology
Air-conditioner becomes low-pressure steam by the low-pressure, liquid refrigerant in the heat exchanger evaporimeter of indoor set, and airborne heat in the absorption chamber reaches the effect that makes the room air cooling.In refrigeration and cooling, the air of indoor higher temperature can condense into condensed water at evaporator surface.The condensed water that is condensed continues to flow down along the evaporator fin gap, and collects in the drip tray below the evaporimeter, discharges outdoor by draining pump again or by outside the condensate draining pipe delivery chamber.
For utilizing draining pump to discharge the air-conditioner of condensed water, the normal and punctual ON/OFF of draining pump is directly connected to the application performance of air-conditioner.
Fig. 1 controls the draining pump drainage switch controlling organization that water pump is discharged condensed water for utilizing switch in the prior art.Draining pump 1 is fixing by water pump support 2, and float 3 floats in the condensed water 5 in the drip tray 4 and with water level and moves up and down.Float 3 connects the drainage switch of draining pumps 1, when the water level of condensed water in the drip tray 4 is elevated to certain position, just opens the drainage switch of draining pump 1 with the raise float 3 that moves up of water level, begins to discharge condensed water 5.Condensed water 5 has been arranged in the drip tray 4, and float 3 is fallen in the drip tray 4, and the drainage switch of draining pump 1 is closed, and stops draining.
The controlling organization of the draining pump drainage switch that constitutes by switch as shown in Figure 1, be according to float height control drainage switch, the accuracy of float perception condensate water level height is low, the problem that water pump float poor response causes condensed water in time to discharge can often occur.And, no matter in the drip tray evaporated condensation water is arranged, as long as air-conditioner is in refrigeration or removes under the wet condition that draining pump is just in running order always, can cause draining pump non-productive work overlong time like this, shorten draining pump service life greatly.
Utilize switch to control existing the problems referred to above of controlling organization that draining pump is discharged the drainage switch of condensed water in the prior art, influenced the product reputation and the market competitiveness of related air-conditioner.
Summary of the invention
The present invention be directed to the existing improvement that utilizes the controlling organization of switch control draining pump drainage switch, its objective is the hydraulic pressure that utilizes piezo-resistance perception condensed water and control the opening and closing of draining pump, so that the condensed water in the drip tray is discharged by PCB (printed circuit control panel).
The opening/closing control mechanism for drainage pump of air conditioner that utilizes piezo-resistance involved in the present invention, comprise and be arranged on cylindrical piezo-resistance in the drip tray, one end of piezo-resistance is fixed on the water discharge pump support, the other end places the condensed water of drip tray, and piezo-resistance connects the PCB (printed circuit control panel) of air-conditioner control part.Piezo-resistance perception bottom condensate water pressure signal, and convert pressure signal to electrical signal transfer and give PCB (printed circuit control panel).When the condensed water pressure of perception reached the pump working water level, when promptly the condensed water in the drip tray need be discharged, signal of signal plumbing pump that PCB can be next according to the piezo-resistance transmission was started working water pump.Water pump stops automatically after three minutes when water level reaches below the working water level.
The opening/closing control mechanism for drainage pump of air conditioner that utilizes piezo-resistance involved in the present invention is by the SEA LEVEL VARIATION of piezo-resistance high accuracy perception condensed water, reach the opening and closing of accurate control draining pump, avoided because of the problem that water pump float poor response causes condensed water in time to discharge occurring; And, also reduced the draining pump non-productive work time, increased the service life of water pump greatly; Meanwhile, the product reputation and the market competitiveness of related air-conditioner have also just been improved.
