Abstract
The utility model provides an air conditioner indoor unit, include: the casing, its cavity that has the electrical apparatus box that holds the air conditioner, air conditioner indoor unit still includes: and the ventilation structure is used for exhausting the air in the cavity. The utility model also provides a split type air conditioner, including preceding air conditioner indoor unit. According to the utility model discloses an air conditioner has reached the effect that improves the safety in utilization of air conditioner indoor with flammable explosion-proof type refrigerant to the messenger is friendly to the environment but flammable explosion-proof type refrigerant such as R290 can the wide application in the air conditioner.
Description
Technical field
The utility model relates to refrigerating field, more specifically, relates to a kind of detachable air conditioner and air conditioner room unit thereof.
Background technology
For flammable can quick-fried type cold-producing medium, as R290 (propane), R290 (propane) is at present universally acknowledged R22 (freon) substitute friendly fully to environment, but, use flammable air conditioner room unit that can quick-fried type cold-producing medium and in air-conditioner, do not promote the use of because of the flammable explosiveness feature of R290.This is because in the application of indoor apparatus of air conditioner, suppose under a kind of failure mode, cold-producing medium R290 reveals from evaporator pipeline, cold-producing medium R290 is present in the formed space of indoor apparatus of air conditioner housing, be provided with electrical equipment in the electrical equipment box because of air conditioner room unit, when the situation that is not seated appears in the electrical equipment binding post in manufacturing process or in the transportation, may cause air-conditioner energising back that the situation of electrical equipment sparking takes place, if R290 has leakage in the indoor evaporator at this moment, the concentration of R290 acquires a certain degree in indoor apparatus of air conditioner, therefore the air-conditioner accident of blasting easily need avoid that indoor set body internal memory leaves R290 when air-conditioner starts.
The prior art air conditioner room unit as shown in Figure 1, comprising: drain pan 10 and lid are located at the panel housing (the panel housing is not shown) on the drain pan, and drain pan 10 is fixed on the inner wall of building body; Air-conditioner air inlet (not shown); Through-flow fan blade 20 is fixed on the drain pan 10; First motor 30 is used to drive through-flow fan blade 20; The evaporimeter (not shown) is arranged on the through-flow fan blade 20, and length is suitable with through-flow fan blade length; Drip tray 70, it has air outlet 701; Electrical equipment box 40 is provided with the control section (hereinafter to be referred as control part) that electrical equipment etc. is used to control the detachable air conditioner operation in it; Through-flow fan blade 20 and the 40 adjacent settings of electrical equipment box, for example electrical equipment box 40 is installed in the right side of through-flow fan blade 20.
The control model of using at present flammable air-conditioner that can quick-fried type cold-producing medium is as described below, after air-conditioner receives enabling signal, the controller of air-conditioner is only given through-flow fan blade 20 enabling signals of indoor set earlier, first motor 30 drives through-flow fan blade 20 and rotates blowing a period of time earlier, if have cold-producing medium to retain in the indoor set, it can be blown out during this period of time, just start air-conditioner then.But when through-flow fan blade 20 rotates, because the length of through-flow fan blade and rigging position restriction, though the air of evaporimeter one side in the air conditioner room unit housing can be blown out through the air outlet 701 of drip tray 70.But in the side that electrical equipment box 40 is installed, the electrical equipment box is installed, in the cavity that housing surrounded, through-flow fan blade 20 can't directly affact, and for the air-conditioner serviceability, the cavity of electrical equipment box 40 sides and the cavity of vaporizer side often will be avoided circulation of air, the speed that causes the cavity air at electrical equipment box 40 places to flow is slow, and the electrical equipment in the electrical equipment box is the source of potential danger, even therefore through-flow fan blade 20 rotates blowing, the circulation of air of electrical equipment box 40 sides is slow, reveal and here stockpile if cold-producing medium has, when the electrical equipment electrical equipment box 40 in lost efficacy when taking place to strike sparks, the blast probability of accident of air conditioner room unit is bigger.
Therefore need to consider that the air of accelerating air conditioner room unit electrical equipment box place cavity flows, before air-conditioner starts, make flammable can quick-fried type cold-producing medium such as R290 can discharge from air conditioner room unit fast, the dangerous hidden danger that eliminating may exist, thus make environmentally friendly but flammable can being widely used in the air-conditioner by quick-fried type cold-producing medium.
The utility model content
