Description

Air conditioner having heating and cooling function

The present invention relates to a combined air-conditioning and air conditioner, and more particularly, to a combined air-conditioning and air conditioner for sufficiently heating a room.

In general, a combined air-conditioning and air conditioner sucks hot air from a room while cooling, exchanges the sucked hot air into cold air, and then discharges the cold air back into the room to cool the room to an appropriate temperature. In the heating, the cold air is sucked in the room, the cold air is exchanged into the hot air by heat exchange, and then the hot air is discharged back into the room to heat the room to an appropriate temperature.

Here, the air-conditioning cycle of the air-conditioning combined air conditioner, when the air conditioner during the cooling, the high-temperature, high-pressure gaseous refrigerant compressed by the compressor installed in the outdoor unit of the air conditioner passes through the four-way valve, the outdoor heat exchanger (condenser) of the outdoor unit Is exchanged with the external air passing through the outdoor heat exchanger while flowing in the outdoor heat exchanger, that is, the heat of the refrigerant is radiated to the outside air so that the refrigerant condenses to a liquid state of medium temperature (45 ° C.) and high pressure. The temperature of the air is raised.

The medium temperature high pressure liquid refrigerant passes through a capillary tube, and at the same time the pressure and the temperature are simultaneously dropped, the liquid refrigerant is partially gasified to be decompressed to a low temperature low pressure state, and the reduced pressure low temperature low pressure refrigerant is a heat exchanger of an indoor unit And heat exchange with the indoor air while flowing in the heat exchanger, that is, the refrigerant absorbs heat from the indoor air, evaporates to a low-temperature, low-pressure gas state, and flows back into the compressor of the outdoor unit, and the indoor air is cooled down. It is discharged to the room in a state that the room is cooled to an appropriate temperature.

And, during heating, the high-temperature, high-pressure gaseous refrigerant compressed by the compressor of the outdoor unit is sent to the heat exchanger (condenser) of the indoor unit while passing through the four-way valve to exchange heat with the indoor air passing through the heat exchanger while flowing in the heat exchanger. That is, the refrigerant dissipates heat into indoor air to condense it into a liquid state of medium temperature (45 ° C.) and high pressure, and the indoor air receives a heat of the refrigerant to increase the temperature, and the indoor air having the elevated temperature is discharged to the room. Therefore, the room is heated to an appropriate temperature.

The liquid refrigerant of the medium temperature and high pressure passes through a capillary tube, and at the same time, the liquid refrigerant is partially gasified to decompress the liquid refrigerant into a low temperature low pressure state, and the reduced temperature low temperature low pressure refrigerant is an outdoor heat exchanger of an outdoor unit. Is exchanged with the external air while being flowed through the outdoor heat exchanger, that is, the refrigerant absorbs heat from the external air, evaporates to a low-temperature, low-pressure gas state, and flows back into the compressor of the outdoor unit. The temperature is lowered.

As shown in Figure 1 to 2b, the structure of the air-conditioning combined air conditioner is the main body 1 is divided into upper and lower, and the upper panel 2 is coupled to the upper front of the main body 1, The lower panel 14 is detachably coupled to the lower part of the front surface of the main body 1, and a control box 15 for generating a control signal to control the operation of the air conditioner is coupled to the lower side of the main body 1. It is.

The upper panel 2 is formed with an inlet opening 4 through which air in the room is sucked, and an inlet opening and closing member rotated by the driving force of the inlet opening / closing motor 6 to open and close the inlet opening 4 on the inlet opening 4 side. (5) is provided, and an air filter (7) is provided in the inlet opening / closing member (5) for filtering dust or foreign matter contained in the hot air of the room sucked into the main body (1).

The inlet opening / closing member 5 is formed in a triangular prism shape which is triangular in plan view, and one side of the inlet opening / closing member 5 is sucked into the body 1 through the inlet 4 through the inlet 4. The grill part 10 is formed, and on the other side of the inlet opening / closing member 5, an open part 11 is formed to be opened so that air sucked through the grill part 10 is sucked into the main body 1. On the other side of the inlet opening and closing member 5 is formed with a closed portion 12 is blocked.

The main body 1 is provided with a cross flow fan 3 which is rotated by the driving force of the fan motor 13 so as to suck the air in the room into the main body 1 and discharge the sucked air into the room during heating and cooling. In the main body 1, a heat exchanger 8 through which a refrigerant flows is installed to heat exchange the air sucked through the suction port 4 by the rotational force of the cross flow fan 3, and the upper panel ( 2) is provided with a discharge port (9) for discharging the air flowing by the rotational force of the cross-flow fan 3 into the room, the discharge port (9) is adjusted to the left and right in the discharge direction of the discharged air The discharge grill 16 for guiding the air flowing along the rear guide 17 to the discharge port 9 is coupled.

When using a combined air-conditioning and air conditioner for cooling, when the user selects the cooling operation mode after supplying power to the air conditioner, the intake port blocking the intake port 4 formed in the upper panel 2 in the state where the air conditioner is stopped. The opening / closing member 5 is rotated by the inlet opening / closing motor 6 which generates a driving force in response to a control signal generated from the control box 15.

That is, the inlet 4 is blocked by the sealing part 12 of the inlet opening / closing member 5, and the grill portion 10 of the inlet opening / closing member 5 rotated by the driving force of the inlet opening / closing motor 6. When the suction port 4 is located, the rotation of the suction opening / closing member 5 is stopped and the suction opening 4 is opened.

As described above, when the inlet 4 is opened, the cross flow fan 3 installed in the main body 1 is rotated by the driving force of the fan motor 13, and is rotated by the rotational force of the rotated cross flow fan 3. The hot air of the room is sucked through the suction port 4, and the hot air of the room sucked through the suction port 4 passes through the grill part 10 and the opening part 11 of the inlet opening / closing member 5 and the main body. (1) is sucked into.

At this time, the dust and foreign substances contained in the hot air of the room sucked into the main body 1 by the air filter 7 installed behind the grill portion 10 of the inlet opening and closing member 5 is caught in the clean state Only air is sucked into the body 1.

On the other hand, the hot air of the room sucked into the main body 1 through the suction port 4 is combined with the main body 1, the heat exchange is made in the process of passing through the heat exchanger (8) where the cool refrigerant flows, the cold The cool air flows in the main body 1 by the rotational force of the cross flow fan 3 which is continuously rotated, that is, the air flowing along the rear guide 17 is discharged while passing through the discharge grill 16. Direction is adjusted and guided to the discharge port (9) is discharged into the room through the discharge port (9), the room is cooled to an appropriate temperature.

In this case, when the operation of the air conditioner is stopped, the inlet opening / closing motor 6 generates a driving force in a direction opposite to that of the cooling operation, and the inlet opening / closing member 5 is rotated along the inlet opening / closing motor 6 to intake ( 3) Since the sealing part 13 of the inlet opening and closing member 5 is located, the inlet 4 is blocked.

Next, when the air conditioner for heating and cooling is used as heating, the power supply is supplied to the air conditioner, and when the user selects the heating operation mode, the inlet opening and closing which closes the inlet 4 formed in the upper panel 2 while the air conditioner is stopped. As the member 5 is rotated by the inlet opening / closing motor 6 generating a driving force, the grille of the inlet opening / closing member 5 is connected to the inlet opening 4 blocked by the sealing part 12 of the inlet opening / closing member 5. Since the part 10 is located, the suction port 4 is opened.

As described above, when the inlet 4 is opened, the cold air in the room is installed in the main body 1 by the rotational force of the cross flow fan 3 which is rotated by receiving the driving force of the fan motor 13. The cold air is sucked into the main body 1 through the grill part 10 and the opening part 11 of the inlet opening / closing member 5.

The cold air of the room sucked into the main body 1 is combined with the main body 1 and heat exchange is performed in the course of passing through the heat exchanger 8 through which the hot refrigerant flows. The discharge direction is adjusted while passing along the discharge grill 16 while flowing along the rear guide 17 in the main body 1 by the rotating force of the cross flow fan 3 which is continuously rotated. As the air is heated to the discharge port 9, the air whose temperature is increased through the discharge port 9 is discharged to the room, and the room is heated to an appropriate temperature.

However, in such a conventional air-conditioning combined air conditioner, the refrigerant flowing in the heat exchanger 8 and the indoor air passing through the heat exchanger 8 are not sufficiently heat-exchanged when heating, and thus the room cannot be sufficiently heated. Consumer confidence in the product is lowered.

In addition, since the cooling and heating efficiency of the air conditioner is reduced by alternately cooling and heating the air conditioner by changing the flow path of the refrigerant in one system, there is also a problem in that the performance of the air conditioner is deteriorated.

The present invention has been made in order to solve the above problems, it is provided with a separate heating device in the lower part of the main body to sufficiently heat the room by the heating device to improve the heating efficiency of the air conditioner There is this.

The plurality of heat dissipation ports, which are emitted from the halogen heater 102 and discharge the heat transferred to the rear of the halogen heater 102, that is, the rear main body 1 of the reflector 101, to the outside of the reflector 101. 103 is formed, and the heat transmitted from the halogen heater 102 and transferred into the rear main body 1 of the reflecting plate 101 is transferred to the upper part of the main body 1 at the upper rear side of the reflecting plate 101. The guide member 104 is guided to the rear of the main body 1 so as to be discharged to the outside through the heat discharging opening 103 and to prevent the discharge member 103, the guide member 104 ) Is positioned directly above each heat outlet 103 so as to smoothly guide the heat to each heat outlet 103.

On the rear surface of the lower panel 14, the heat shield plate 105 which radiates from the halogen heater 102 and is transferred into the rear main body 1 of the reflector 101 to block the heat from being transferred to the control box 15. The heat shield plate 105 is coupled to face the rear of the main body 1, and the heat shield plate 105 is transferred into the rear main body 1 of the halogen heater 102 by heat rising to the upper part of the main body 1 by convection. The control box 15 is installed directly above the reflection plate 101 to prevent damage, and the heat shield plate 105 is emitted from the halogen heater 102 and transferred into the rear main body 1 of the reflection plate 101. Concave grooves 105a are formed to collect the heat rising to the upper side and to convex the heat to the lower side.

On the front surface of the reflector plate 101, a honeycomb-shaped dispersion plate 106 is provided to disperse heat radiated from the halogen heater 102 and radiated forward by the reflector plate 101, and the reflector plate 101 is provided.

The front of the door 108 is provided for opening and closing the heating port (14a).

Since the halogen heater 102 is filled with halogen in a long rod-shaped glass sphere, when the power is applied, the halogen heater 102 emits high heat while generating heat and light, and the reflecting plate 101 radiates heat emitted from the halogen heater 102. It has a semi-cylindrical shape so that it can be radiated forward.

The operation of the present invention configured as described above is as follows.

Next, in order to heat the room, operate the heating system provided in the upper part of the main body 1 of the combined air-conditioning and air conditioner, or operate the heating device provided in the lower part of the main body 1 or the heating system and the heating device. Operate simultaneously.

Here, a state in which only the heating device provided in the lower part of the main body 1 operates to heat the room will be described. The door 14a of the heating opening 14a formed in the lower panel 14 coupled to the lower front surface of the main body 1 108 is detachably installed, i.e., the door 108 is coupled to the heating port 14a when the heating device is not used, and the door 108 is opened at the heating port 14a when the heating device is used. Remove it.

As described above, when the door 108 is removed from the heating port 14a of the lower panel 14 and the heating device is operated, the reflector 101 coupled to the rear surface of the heating port 14a of the lower panel 14 is operated. In the plurality of halogen heaters 102 arranged at regular intervals therein, heat and light are emitted and emit high heat, and the emitted heat and light are radiated forward as much as possible by the reflector 101.

The heat radiated forward is evenly distributed while passing through the honeycomb-shaped distribution plate 106 installed on the front surface of the reflector plate 101, and the dispersed heat passes through the heating grill 107 and through the heating port 14a. As the air temperature of the room is increased by the heat transferred to the room, the air whose temperature is increased is raised upward by natural convection, and thus the room is heated to an appropriate temperature and the halogen heater 102 ), Ultraviolet rays are emitted, so a therapeutic effect can be expected.

At this time, heat emitted from each halogen heater 102 is transferred to the rear main body 1 of the halogen heater 102, that is, the rear main body 1 of the reflector 101, and the heat transferred into the main body 1 is natural. It is raised upward by convection.

The plurality of heat dissipation ports formed in the upper portion of the reflecting plate 101 by the guide member 104 formed on the upper portion of the reflecting plate 101 so that the heat rising upward by the natural convection phenomenon is directed toward the rear of the main body 1. Guided to (103) is discharged to the outside of the main body 1 through each of the heat discharge port (103).

As described above, the heat discharged into the room through each heat discharge port 103 and the heat radiated from the halogen heater 102 and radiated forward by the reflector 101 are combined with the heat transferred to the room through the heating port 14a. As the heat is moved from the lower part to the upper part of the room by natural convection, the room is heated.

(1) The heat transferred into the upper portion by the convection phenomenon is primarily blocked by the guide member 104 to be guided to each heat outlet 103 and not blocked by the guide member 104. As the secondary block is blocked by the heat shield plate 105, the heat is prevented from being transferred to the control box 15, thereby preventing deformation and damage of the control box 15.

In addition, since the recess plate 105a is formed in the heat shield plate 105, the heat blocked by the heat shield plate 105 is transferred into the rear main body 1 of the reflector plate 101 and upwards, so that the recess groove 105a is formed in the heat shield plate 105. At the same time as being collected in the 105a and convex to the lower side by the concave groove 105a, the heat is prevented from being transferred to the control box 15 and the heat is discharged to the lower portion of the main body 1 while the heat discharging opening 103 is opened. It is discharged smoothly through the outside.

Here, when the heating device is not used or the operation of the heating device is stopped, the door 108 is coupled to the heating port 14a, and the dust and foreign substances in the room are reflected through the heating port 14a. The heating port 14a is prevented from being introduced into the outer periphery of the halogen heater 102 and the door 108 is removed from the heating port 14a when the heating device is used.
