In addition, the drive part 81 of electric expansion valve 80 is positioned at contour with channel part 82 or higher than channel part 82 position.If drive part 81 is positioned at the position lower than channel part 82, then the pressure being applied to the cold-producing medium of drive part 81 by channel part 82 can affect the durability of the valve module be arranged in drive part 81.
Electronic building brick (such as, circuit board) for controlling the operation of the indoor unit 2 of air-conditioning is arranged in control unit 50.Control unit 50 is arranged on a side of the inside of main body 20, and electric expansion valve 80 is arranged between the outside of control unit 50 and indoor heat converter 30 longitudinal direction.That is, between the outside of spatial accommodation 70 heat exchanger 30 disposed in the interior longitudinal direction and control unit 50.
Condensed water is formed in main body 20, specifically, due to temperature difference cold-producing medium and air between forms condensed water near the indoor heat converter 30 flowed at cold-producing medium and electric expansion valve 80 wherein.In order to prevent condensed water from causing electricity to damage to the electronic building brick be arranged in control unit 50, need to prevent condensed water to be introduced in control unit 50.
Control the inside that control unit 50 is fixed to main body 20 by housing 60, and prevent condensed water to be introduced in control unit 50.Control housing 60 to comprise control unit 50 and be installed in mounting portion 61 wherein, sidewall 62 between control unit 50 and indoor heat converter 30 and for drive motors 42 being fixed to the motor standing part 67 on rear board 22.Motor standing part 67 is formed as the shape of the front surface portion around drive motors 42, thus also prevents condensed water to be introduced in drive motors 42 and drive motors 42 electricity is damaged.
Sidewall 62 comprises the first side surface portion 63, the extension 64 be connected with the first side surface portion 63, the second side surface portion 65 be connected with extension 64 and the ledge 66 be formed on the second side surface portion 65.
First side surface portion 63 is arranged between control unit 50 and electric expansion valve 80 along vertical direction.Control unit 50 and electric expansion valve 80 are flatly separated by the first side surface portion 63.In addition, the side of extension 64 is connected with the first side surface portion 63, and extension 64 extends designated length towards the direction of indoor heat converter 30.Electric expansion valve 80 can be positioned on extension 64.Therefore, two adjacently situated surfaces of spatial accommodation 70 are limited by the first side surface portion 63 and extension 64.
Extension 64 comprises: targeting part 64a, and be provided with from the first side surface portion 63 towards the downward-sloping leading section of water collector 90, this leading section has certain altitude; Water containing section 64b, water containing section 64b is inclined upwardly from the upper side and lower side of the leading section of targeting part 64a respectively.Water containing section 64b can be constructed such that the two ends not adjacent to each other of water containing section 64b are inclined upwardly, and in this case, extension 64 is roughly V-shaped.Certain difference in height is there is between the end that water containing section 64b is adjacent one another are.The condensed water formed around electric expansion valve 80 is collected along the path formed by water suction part 64b and targeting part 64a.
Second side surface portion 65 is connected with extension 64, and downward-sloping.In addition, be formed on the second side surface portion 65 towards the ledge 66 that water collector 90 is outstanding.Ledge 66 can be downward-sloping towards water collector 90.Water collector 90 is arranged under ledge 66, and the condensed water dripped from ledge 66 is accommodated in water collector 90.
Fig. 7 is the view of the discharge-channel of the condensed water illustrated in the indoor unit of the air-conditioning according to embodiment.
By driving fan blowing 41, room air is inhaled in main body 20 by suction hole 21a, filters out impurity from described room air simultaneously.The air be inhaled into carries out heat exchange through indoor heat converter 30, is then discharged into the interior space by fan blowing 41 through discharge orifice 21b.Here, the condensed water formed around indoor heat converter 30 is collected in the water collector 90 under heat exchanger 30 disposed in the interior, is then discharged into the outside of main body 20 through scupper hose 92.
As shown in Figure 7, also condensed water is formed being exposed to around the electric expansion valve 80 of room air.Condensed water is collected in the path that water containing section 64b by being arranged in the extension 64 under electric expansion valve 80 and targeting part 64a is formed.The condensed water collected flows through the second side surface portion 65, then drops onto water collector 90 from ledge 66.Therefore, the condensed water formed around electric expansion valve 80 is not introduced in control unit 50 and drive motors 42, and is discharged into the outside of main body 20.
As clear from the above description, reduce according to the indoor unit of the air-conditioning of embodiment and cost required for independent electric expansion valve and space are installed, and simplify the installation process of electric expansion valve.
In addition, although in electric expansion valve unit disposed in the interior, the external dimensions of indoor unit does not increase, and the capacity of heat exchanger does not reduce, thus maintains the heat exchanger effectiveness of indoor unit.
