CN2551918Y - Mould-proof air-conditioner indoor unit - Google Patents

Abstract

The utility model discloses an indoor unit of a mildewproof air conditioner. A humidity sensor is arranged in the indoor unit; bacteria and mold multiplication is prevented by automatically drying condensed water on an evaporator to improve the intelligent health level of the air conditioner. The utility model has simple structure, convenient adjustment and strong practicability.

Description

The mildew-resistant air conditioner room unit

One, technical field

The utility model relates to the air-conditioner field, particularly a kind of mildew-resistant air conditioner room unit.

Two, background technology

Existing split type Dan Leng, changes in temperature, the auxilliary pattern of fever air-conditioner of electricity, constitute by compressor, condenser, evaporimeter, cross valve, capillary and automatically controlled detection part thereof, during use, refrigeration or when dehumidifying after after a while, the water outlet of can condensing on the evaporimeter of its indoor set, make evaporimeter be in dampness always, after stopping refrigeration or dehumidifying, do not have the wind circulation on the evaporimeter, water is difficult to natural evaporation and falls, become the hotbed of bacterium, gone mouldy easily, very unfavorable to health.

Three, summary of the invention

The purpose of this utility model is intended to air conditioner room unit is improved, a kind of mildew-resistant air conditioner room unit simple and reasonable, easy to adjust is provided, close refrigeration or dehumidifying back automatic drying indoor set, can prevent growing and stop and going mouldy of bacterium very effectively.

Indoor machine of air-conditioner generally comprises chassis, face frame, wind wheel, evaporimeter, wind guide strip etc.

The utility model improvements over the prior art are that humidity sensor is installed in air conditioner room unit.

The inventor finds that through exploitative experiment when humidity sensor was installed in air inlet or air outlet, the effect of detection and controlled humidity was preferable.

Humidity sensor also can be installed on the evaporimeter.

Described humidity sensor can be installed in a position or two and the above position in the indoor set.

The utility model increases humidity sensor at its indoor set on the basis of existing air-conditioner, the condensed water on the energy automatic drying evaporimeter, prevent bacteria breed, stop to go mouldy, improve the intelligent general level of the health of air-conditioner, it is simple in structure, and is easy to adjust, practical.

Four, description of drawings

Fig. 1 is the structural representation of the utility model mildew-resistant air conditioner room unit;

Fig. 2 is the operation principle block diagram of Fig. 1.

Five, the specific embodiment

As shown in Figure 1, its indoor set comprises that mainly chassis 1, face frame 2, wind wheel 3, evaporimeter 4, wind guide strip 5 constitute, and humidity sensor is installed on indoor set air inlet 6 and the air outlet 7.As shown in Figure 2, the operation principle of Fig. 1 and control method are as follows:

By the electric-controlled parts of air-conditioner detect be system after normally closing refrigeration or dehumidifying, compressor stops, indoor fan is with a lower rotational speed N operation, angle [alpha] of wind guide strip revolution, humidity sensor detects the humidity value RH of return air _INLETHumidity value RH with air-out _OUTLET, definition ξ $\mathrm{\ξ}=\frac{|{\mathrm{RH}}_{\mathrm{OUTLET}}-{\mathrm{RH}}_{\mathrm{INLET}}|}{{\mathrm{RH}}_{\mathrm{INLET}}}\×100\%$

When ξ＜5%, think that the water on the evaporimeter dries up, this moment close chamber's inner blower, wind guide strip is also closed.

With 1.5 Split Type Domestic Air is example, and each parameter value is as shown in table 1.

Table 1

Parameter
		N(RPM	800
α(°)	30

So control can guarantee that this air conditioner room unit can not go mouldy.
