Abstract

In case of a FF type air conditioner, oxygen lacking and dust inflowing problems occure when air only circulates in room. The air conditioner supplies the positive pressure into room to resolve these problems. It has a positive pressure developing device (100) at the lower part of a housing. The positive pressure developing device meets with a outer air induction pipe (110). The amount of room air induced through an induction pipe (12) is constant to bring lack of oxygen and accumulation of dust in the air. This phenomenon occurs with the positive pressure into room to prevent outer air from inducing. When outer fresh air is supplied into a room, a headache occuring from lack age of oxygen can be resolved.

The present invention relates to a cooling and heating device, and more particularly to a domestic cooling and heating device to provide a positive pressure to the room from the FF type heating and cooling device to block the intake of external dust and the like.

In general, the FF type air-conditioning unit has a filter for filtering the air sucked into the main body is installed in the lower part of the main body, the circulation fan portion for inhaling the air is installed in one part of the main body, the indoor air sucked through the circulation fan unit is cooled Or it is cooled or heated through the heat exchanger for heating and discharged to the front room. Referring to the cooling apparatus of FIG. 1 as an example, the filter 11 is installed at the lower position inside the housing 10, and the front plate 10-1 portion of the housing 10 in which the filter 11 is installed. The suction hole 12 is formed, the circulation fan 13 is installed in the center of the housing 10, the evaporator 14 is fixed to the upper end of the housing 10, the housing corresponding to the evaporator 14 The discharge hole 15 is formed in the upper portion of the front plate 10-1 of 10. In the drawings, the condenser and the circulation fan driving wires are omitted.

The operation principle thereof is an evaporator 14 which filters the air sucked through the filter unit 11 through the suction of the air into the housing 10 through the suction hole 12 and forms a heat exchange unit through the circulation fan 13. By the cold air, and is discharged to the outside of the housing 10 through the discharge hole (15). In this case, the circulation fan unit 13 provides a forced air circulation path for sucking the air in the room through the suction hole 12 to be discharged to the discharge hole 15.

Such a cooling device is sucked into the indoor air through the suction hole 12 in the lower front of the housing 10 and cooled, and discharged into the room through the discharge hole 15 in the upper front of the housing 10, the indoor air Repeat to cycle. Therefore, due to the nature of the products used in the enclosed space, if such a device is in operation for several hours, there is a side effect such as the head hurts due to lack of oxygen and dust sucked from the outside, simply circulating the indoor air Since the dust is introduced into the room during the circulation, such as glass windows, there was a hygiene problem.

The present invention is to solve this problem by adding a means for providing a positive pressure in the room under the FF-type heating and cooling device, characterized in that to block the inflow of external dust in addition to the cooling, heating function. That is, the outside air suction hole is installed at the lower end of the inside of the housing of the air-conditioning device, and the positive pressure generating means is installed at the lower part of the outside air suction hole and the filter unit.

DETAILED DESCRIPTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the same structures as those in the related art are denoted by the same reference numerals and description of the same structure will be omitted.

The present invention forms an outside air suction hole (110) in the inner bottom of the housing 10, the back plate (10-2) of the heating and cooling device, and the positive pressure generating means (100) below the outside air suction hole (110) and the filter unit (11). It is installed. The positive pressure generating means 100 is an external air fan 120 which is installed to contact the outside air suction hole 110, a heating unit 130 for selectively warming the sucked outside air, and the outside air fan 120 and the heat generating unit It is made of a case 140 surrounding the 130 to form a passage of the suction outside air. In the space between the positive pressure generating means 100 and the filter unit 11 includes a directional container 160, a nozzle 164 fixed to the top of the directional container 160 and selectively sprayed by the solenoid valve 162 Is done. Where the case 140 and the front plate 10-1 is in contact with the guide hole 150 is formed. It will be appreciated by those skilled in the art that the heating generator 130 in the present invention can be variously designed and configured by a hot water heating method connected to a hot water pipe of a heater or a hot water boiler using electricity.

In describing the present invention configured as described above, the method of circulating the suction hole 12, the filter part 11, the circulation fan part 13, the heat exchanger evaporator 14, and the discharge hole 15 in order is known. Description of the principle of operation will be omitted. (In the drawing, the cooling device without the condenser is described. However, the cooling and cooling device (with a condenser) can be installed and used). The present invention provides a cooling and heating device (a cooling device in the drawing) in a state in which a positive pressure generating means (100) is installed at an inner lower end of the housing (10) so as to penetrate the outside air suction hole (110) of the back plate (10-2) of the housing (10). By activating), when the indoor air passes through the filter unit 11 through the suction hole 12, the positive pressure generating means 100 is operated at the same time. (It can be operated at the same time by the operation panel (not shown) and wiring, the description of the principle is omitted.)

At this time, there is no change in the air pressure in the room when the amount of indoor air sucked and discharged through the suction hole 12 and the discharge hole 15 is constant, but the outside air is absorbed by the positive pressure generating means 100. When the fan unit 120 uses the heating unit 130 at a predetermined temperature (for example, when it is used as a cold outside air heater, it is necessary to set the heating unit 130 to approach a cold outside air to an indoor temperature. In this case, it is of course not necessary to heat the heating unit 130) and is provided to the filter unit 11.

That is, the amount of indoor air introduced through the suction hole 12 is constant, but since the outdoor air introduced by the positive pressure generating means 100 is further introduced into the filter unit 11 (additional outdoor air flow in FIG. The pressure discharged into the room through the discharge hole 15 is greater than the pressure sucked through the suction hole 12. Therefore, the air pressure is counted (positive pressure is generated), and thus the dust in the room is discharged to the outside, but the outside dust is not introduced into the room.

In addition, when the fragrance in the fragrance container 160 is injected through the nozzle 164 due to the operation time interval of the solenoid valve 162 set by the fragrance in the fragrance container 160, the fragrance is discharged to the room by the fragrance. Will be. This allows the solenoid valve 162 to be operated once or twice a day or several times per day when the operation panel is set, and the time per one can be changed or used as needed, of course, such a solenoid valve ( The description of the control technique of 162 is generally omitted.

As described above, the present invention uses the principle of the present invention in various cooling and heating devices of the FF method, so that there is no dust inflow into the room, and the room is clean, and the fresh air is continuously injected into the room through the air intake air, thereby operating for a long time. There is no side effect that the head hurts, and when used in the heater, because the outside air is heated to the room temperature supplied from the heating unit can reduce energy waste due to the inflow of outside air.
