Abstract
The utility model relates to an air conditioner, comprising a heat exchanger (1), a fan (2), a defrosting tray (3), a liquid level sensing device (4). The fan (2) is arranged at the edge of the heat exchanger (1); the defrosting tray (3) is arranged below the heat exchanger (1); the liquid level sensing device (4) is positioned in the defrosting tray (3), wherein, the liquid level sensing device (4) is a temperature sensor. The utility model uses the temperature sensor to replace the conventional water level switch as a liquid level sensing device structure, and thus, the utility model not only reduces the cost of the air conditioner, but also improves the service performance of the air conditioner. The utility model has the advantages of smart design and good performance.
Description
1, technical field:
The utility model is a kind of air-conditioning that adopts temperature sensor as its liquid level sensing device, belongs to the renovation technique of air-conditioning.
2, background technology:
At present the home and abroad air-conditioning all uses water level switch as liquid level sensing device, because water level switch is a mechanical switch, not only cost is higher for it, and the accuracy of the reliability of using, detection is not good enough, has directly influenced the production cost and the serviceability of air-conditioning.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and provides a kind of and replace the air-conditioning of conventional water level switch as liquid level sensing device with temperature sensor.The utility model both can reduce the production cost of air-conditioning, can improve the serviceability of air-conditioning again.
Structural representation of the present utility model as shown in Figure 1, include heat exchanger (1), blower fan (2), drip tray (3), liquid level sensing device (4), blower fan (2) places the side of heat exchanger (1), drip tray (3) places the below of heat exchanger (1), liquid level sensing device (4) places in the drip tray (3), and wherein liquid level sensing device (4) is a temperature sensor.
Above-mentioned liquid level sensing device (4) is installed in the safety level height zone in the drip tray (3).
The utility model is owing to adopt temperature sensor to replace the structure of conventional water level switch as liquid level sensing device, and therefore, the utility model both can reduce the production cost of air-conditioning, can improve the serviceability of air-conditioning again.The utility model is that a kind of design is ingenious, well behaved air-conditioning.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model.
5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include heat exchanger (1), blower fan (2), drip tray (3), liquid level sensing device (4), blower fan (2) places the side of heat exchanger (1), drip tray (3) places the below of heat exchanger (1), liquid level sensing device (4) places in the drip tray (3), and wherein liquid level sensing device (4) is a temperature sensor.
Above-mentioned liquid level sensing device (4) is installed in the safety level height zone in the drip tray (3).In the present embodiment, liquid level sensing device (4) is installed in the middle and upper part of drip tray (3), it is former water level switch altitude measurement place, temperature sensor is experienced the variation of liquid level, and signal is passed to the control device of air-conditioning, control device is by the temperature that temperature sensor is experienced and the contrast of environment temperature, whether the water level of judging condensed water has arrived the safety level height, again the running of air-conditioner is controlled, to prevent causing the problem that condensed water overflows drip tray to take place owing to the impeded drainage that draining pump damages or other reasons causes.
In the operation process of air-conditioner, liquid level sensing device has following two kinds of duties:
1) when the water level no show safety level of the condensed water A in the air-conditioner drip tray (3), the temperature sensor impression be air themperature, the control device of air-conditioning will be this temperature and environment temperature comparison.Comparative result is that this temperature difference is very little, and air-conditioner then continues to run well.
2) when the liquid level that causes the condensed water A in the air-conditioner drip tray (3) owing to certain accidental cause surpasses safety level, what temperature sensor was experienced is lower condensate temperature, the difference of this temperature and environment temperature is bigger, the control device of air-conditioning then sends signal shuts down air-conditioner, thereby prevents that condensed water from overflowing drip tray.
Claims (2)
1, a kind of air-conditioning, include heat exchanger (1), blower fan (2), drip tray (3), liquid level sensing device (4), wherein blower fan (2) places the side of heat exchanger (1), drip tray (3) places the below of heat exchanger (1), liquid level sensing device (4) places in the drip tray (3), it is characterized in that liquid level sensing device (4) is a temperature sensor.
2, air-conditioning according to claim 1 is characterized in that above-mentioned liquid level sensing device (4) is installed in the safety level height zone in the drip tray (3).
