Figure 1 shows that the schematic perspective view of the indoor set of existing air pipe type air-conditioner.As shown in Figure 1, the indoor set of existing air pipe type air-conditioner mainly comprises: housing 5, be arranged on the heat exchanger 4 in the housing 5, be arranged on the drain pan 3 of housing 5 belows, the fan (not shown) that the upstream side of a plurality of outsides that place housing 5, heat exchanger 4 is surrounded by fan housing 6, the exhaust outlet of fan housing 6 is positioned on the rear board of housing 5 and towards a side of heat exchanger 4, but the place between a plurality of fan is provided with the motor 7 of drive fan.The housing 5 in this external heat exchanger the place ahead is provided with air outlet 2, and air outlet 2 is provided with the wind blade (not shown).As shown in the figure, the length of drain pan 3 is longer than the length of housing 5, and housing 5 is positioned at a side of drain pan, and the sidewall of drain pan opposite side is provided with osculum 1.
There is following shortcoming in above-mentioned prior art:
The part of drain pan is exposed outside and osculum only has a place, and the osculum phenomenon of blocking appears in dust in environment more easily, influences the normal use of air-conditioning.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of be provided with often begin to rehearse a water hole and a normally closed osculum, when often beginning to rehearse the water hole obstruction, normally closed osculum is opened the drain pan of the air duct type air conditioning indoor machine that carries out draining.
The objective of the invention is to be achieved through the following technical solutions:
A kind of drain pan of air pipe type air conditioner indoor unit, comprise: the osculum that is arranged on drain pan one side, connection drainpipe, on the sidewall of drain pan, also be provided with a normally closed osculum that connects drainpipe, in the drainpipe at normally closed osculum place, be provided with normally closed draining valve, the liquid-level switch device also is installed on the sidewall of drain pan, when the liquid level in the drain pan was enough high, described liquid-level switch device started described normally closed draining valve and carries out draining.
Above-mentioned liquid-level switch device is a floating-ball level switch.
Above-mentioned normally closed draining valve comprises: be used to block normally closed osculum and the inner conical stopple that is provided with magnet; Be arranged on the installing ring of the annular at stopple top; One end is fixed on the installing ring, the other end is fixed on a plurality of springs on the drainpipe tube wall; The adhesive plate that is positioned at the inboard of normally closed osculum and stopple and is provided with at interval with stopple, described adhesive plate is fixed on by fixture on the sidewall of drain pan, is provided with coil in the adhesive plate, and described coil is connected with the control circuit of normally closed draining valve.
Above-mentioned spring is 2 or a plurality of, and above-mentioned magnet is injection-moulded in stopple, and coil is injection-moulded in the adhesive plate, and the adhesive plate is made by ambroin.
Above-mentioned normally closed osculum and above-mentioned osculum are arranged on the same side or are arranged on the opposite side of osculum.
The drain pan of air duct type air conditioning indoor machine of the present invention has one to be normally closed osculum in two osculums of drain pan.After the osculum of often opening stopped up, when water level rose to certain altitude, floating-ball level switch was transferred to control panel with signal, under the effect of control circuit, normally closed osculum is opened, and normally closed osculum is closed after water level descends, thereby can guarantee the normal operation of air-conditioning.

The specific embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to the drain pan of air pipe type air conditioner indoor unit of the present invention.
As Fig. 2～shown in Figure 4, the drain pan 20 of air pipe type air conditioner indoor unit of the present invention comprises: be arranged on drain pan a side, connect the osculum 21 of drainpipe.In addition, on the sidewall of drain pan 20, also be provided with a normally closed osculum 24 ' that connects drainpipe, in the drainpipe 24 that normally closed osculum 24 ' is located, be provided with normally closed draining valve, floating-ball level switch device 23 also is installed on the sidewall of drain pan.Floating-ball level switch device 23 is fixed on the drain pan 20 by installing plate 25.When the liquid level in the drain pan 20 was enough high, liquid-level switch device 23 started normally closed draining valve and carries out draining.
Described normally closed draining valve comprises: be used to block normally closed osculum 24 ' and the inner conical stopple 26 that is provided with the magnet (not shown); Be arranged on the installing ring (not shown) of the annular at stopple 26 tops; A plurality of springs 22 on the tube wall that one end is fixed on the installing ring, the other end is fixed on drainpipe 24; The adhesive plate 27 that is positioned at the inboard of normally closed osculum 24 ' and stopple 26 and is provided with at interval with stopple, adhesive plate 27 is fixed on the sidewall of drain pan 20 by fixture 28, be provided with the coil (not shown) in adhesive plate 27, coil is connected with the control circuit of normally closed draining valve.
Described liquid-level switch device is a floating-ball level switch.Because the structure of floating-ball level switch and principle are known in the art, so its structure is not elaborated at this.Floating-ball level switch is connected with the control circuit of normally closed draining valve, liquid level in drain pan reach a certain height, for example: during 17mm, floating-ball level switch is connected the control circuit of normally closed draining valve, that is: make coil electricity in the adhesive plate 27, produce magnetic field, thereby the conical stopple 26 that magnet is equipped with in inside is moved to the direction away from osculum with 27 adhesives of adhesive plate, conical stopple 26, carry out draining thereby open normally closed osculum 24 '.Water level in drain pan 20 drops to certain altitude, for example during 10mm, makes the coil blackout in the adhesive plate 27, thereby closes normally closed osculum.
As shown in FIG., described spring 22 is symmetrically arranged with 2, can certainly be provided with a plurality of.Described magnet is injection-moulded in stopple 26, and described coil is injection-moulded in adhesive plate 27, and adhesive plate 27 is made by ambroin.
Though as shown in FIG., normally closed osculum 24 ' is arranged on the opposite of osculum 21, and it also can be arranged on the same side of drain pan with osculum 21.
