Description

Air Conditioning for Air Conditioning

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.

In the heating, the refrigerant, which is a gaseous state of high temperature and high pressure, 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 radiates heat to the indoor air to condense to 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 indoors. The room is heated to an appropriate temperature because it is discharged.

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 the other side of the inlet opening and closing member 5 is formed with an open opening 11, and the other side of the inlet opening and closing member 5 is closed. It is formed of (12).

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 to solve the above-mentioned problems, the heating device is provided in the lower part of the main body, and the protective device for protecting the heating device in front of the heating device to install a sufficient room by the heating device The heating is to improve the heating performance of the combined air-conditioning and air conditioner, and the purpose of preventing the protection and safety accident of the heating device in advance.

In order to achieve the above object, the present invention combines the upper panel with the inlet and the discharge port formed in the upper front of the main body, the lower panel in the front lower portion of the main body to open and close the air sucked into the main body In the air-conditioning combined air conditioner for heating and cooling the room by heat exchange, the lower panel is provided with a heating port, the rear heating port of the lower panel is provided with a heating device for heating the room, and in front of the heating device Provided is a combined air conditioning and air conditioner, characterized in that provided with a heating protection means for protecting the heating device.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

Since the air conditioner for both air conditioning and heating has been mentioned in the conventional configuration, overlapping parts are omitted, and only the same structure is given the same reference numeral as in the prior art.

Figure 3 is an exploded perspective view showing a heating apparatus of the present invention of a combined air-conditioning and air conditioner, Figure 4 is a cross-sectional view showing a cross-sectional view of the heating apparatus of the present invention, the subject innovation is divided into upper and lower body (1) An upper panel 2 having an inlet 3 and an outlet 9 is coupled to an upper portion of the front surface, and a lower panel 14 is coupled to the lower portion of the front surface of the main body 1 so as to be opened and closed.

The lower panel 14 is provided with a heating port 14a, the rear heating port 14a of the lower panel 14 is provided with a heating device for heating the room, and in front of the heating device Heating protection means for protecting the heating device is provided.

The heating device is provided with a plurality of halogen heaters 102 arranged at regular intervals in the heating port 14a to heat and emit heat and light, respectively, and to the rear of the rear heating port 14a of the lower panel 14. Each halogen heater 102 is installed and a reflecting plate 101 for radiating heat and light emitted from each halogen heater 102 into a room through a heating port 14a is coupled, and the reflecting plate ( A dispersing plate 103 is provided on the front surface of 101 to disperse heat radiated from each halogen heater 102 and radiated to the front of the main body 1 by the reflecting plate 101.

The dispersion plate 103 is formed in a honeycomb shape to evenly distribute heat radiated to the front of the main body 1.

The upper portion of the reflector plate 101 is discharged from the halogen heater 102 to discharge heat transferred to the rear of the halogen heater 102, that is, the rear body 1 of the reflector plate 101 to the outside of the body 1. A plurality of heat dissipation holes 101a are formed.

The heating device protection means easily radiates heat radiated from each halogen heater 102 to the front of the main body 1 by the reflector 101 to the outside and protects each halogen heater 102 as the heating device. At the same time, the heating grill 104 to protect the user from the high-temperature halogen heater 102, the heating grill 104 is installed in front of the reflector plate 101 is formed in a grid.

In front of the front heating port 14a of the lower panel 14, the heating port 14a is blocked when the heating device is not used, and the heating port 14a is opened to open the heating port 14a when the heating device is used. The door 105 which opens and closes) is detachably installed.

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.

In order to heat the room, the heating system provided at the upper part of the main body 1 of the combined air-conditioning and air conditioner is operated or the heating apparatus provided at the lower part of the main body 1 is operated, or the heating system and the heating device are operated. Operate simultaneously.

Here, the state of heating the room by operating only the heating device provided in the lower part of the main body 1 will be described.

First, the door 105, which is detachably coupled to the heating port 14a formed on the lower panel 14 coupled to the lower front surface of the main body 1, is detached from the lower panel 14, and then the heating device is operated. When a plurality of halogen heaters 102 are arranged at regular intervals in the reflecting plate 101 coupled to the rear surface of the heating port 14a of the lower panel 14, heat and light are generated and emit high heat. Heat and light emitted are radiated toward the front of the main body 1 as much as possible by the reflector 101.

The heat radiated forward is evenly distributed while passing through the honeycomb-shaped distribution plate 103 installed on the front surface of the reflector plate 101, and the dispersed heat passes through the heating grill 104 and through the heating port 14a. The heating grill 104 installed in front of the reflector plate 101 is formed in a lattice shape, and thus is radiated from each halogen heater 102 and radiated to the front of the main body 1 by the reflector plate 101. The heat is not only easily released to the outside by the heating grill 104 but also protects the user from each halogen heater 102 of high temperature and at the same time protects each halogen heater 102 from the outside.

In this way, as the air temperature of the room is increased by the heat transferred to the room, the air whose temperature is raised rises upward due to natural convection and heats the room to an appropriate temperature, and at each of the halogen heaters 102. Ultraviolet rays are emitted, so you can expect a therapeutic effect.

In this case, when the operation of the heating device is stopped or the heating device is not used, the door 105 is coupled to the heating port 14a to block the heating port 14a so that dust and foreign matters may enter through the heating port 14a. It prevents flowing into the reflector plate 101 and adheres to the outer periphery of the halogen heater 102. When using the heating device, the door 105 is removed from the heating port 14a to open the heating port 14a. Then use heating.

Meanwhile, most of the heat dissipated by each halogen heater 102 is radiated to the front of the main body 1 by the reflector 101, and a part of the heat dissipated by the halogen heater 102 is transferred to each of the halogen heaters 102. In other words, it is transmitted into the rear main body 1 of the reflecting plate 101.

As described above, the heat transferred into the main body 1 is discharged into the room through the plurality of heat dissipation holes 101a formed on the upper portion of the reflecting plate 101 while rising upward in the main body 1 by natural convection.

Therefore, heat radiated from the respective halogen heaters 102 and radiated by the reflecting plate 101 to the front interior of the main body 1 and transferred from the respective halogen heaters 102 into the main body 1 to dispose each of the heat radiating openings 101a. Since the heat discharged into the room is combined, the combined heat is used to heat the room while flowing in the room according to natural convection.

As described above, the present invention provides a heating device in the lower part of the main body, thereby operating the heating device provided in the lower part of the main body even if the room is not sufficiently heated by the air conditioning system installed in the upper part of the main body. Since the room can be sufficiently heated, there is an effect that the heating performance of the air-conditioning combined air conditioning unit is improved.

In addition, since a grid-type heating grill, which is a heating device protection means, is coupled to the front of the heating apparatus, the heat radiated from each halogen heater by the heating grill and radiated by the reflector is not only easily released to the front of the main body, but also the heating. In addition to protecting each halogen heater of the device at the same time to protect the user from each of the high-temperature halogen heater to prevent accidents in advance, there is also an effect of improving the consumer's reliability of the product.
