The following describes the preferred technical solution of the double tubular air conditioner internal unit of the embodiment of the present invention.

Fig. 1 is a front view of a double tubular air conditioner internal unit provided by an embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line A-A in Fig. 1. As shown in Figures 1 and 2, this embodiment provides a dual tubular air-conditioning internal unit 10, which includes a housing 1, and the housing 1 has a first air duct 11 and a second air duct at least partly separated from the air outlet. A separate heat exchanger 2 and a cross-flow fan 3 are provided in the first air passage 11 and the second air passage 12, respectively. The heat exchanger 2 is located between the air inlet of the air passage and the cross-flow fan 3 for Exchange heat, the cross flow fan 3 is used to drive the air in the external environment from the air inlet of the air duct into the air duct, and the air after the heat exchange by the heat exchanger 2 is discharged from the air outlet of the air duct to the room to achieve cooling Or heating. When the air conditioner is heating, hot air blows into the room to reduce the humidity of the indoor air.

Specifically, a separation device 4 is provided inside the housing 1, and the separation device 4 separates the first air passage 11 and the second air passage 12. Among them, it is understandable that the air inlet of the first air duct 11 and the air inlet of the second air duct 12 may be the same, or the air inlet of the first air duct 11 and the air inlet of the second air duct 12 are also Separate. Illustratively, the air inlet of the first air duct 11 and the air inlet of the second air duct 12 are respectively arranged on the left and right sides of the rear side wall of the housing 1.

The air outlet of the first air duct 11 and the air outlet of the second air duct 12 may be respectively formed on the left side wall and the right side wall of the housing 1, thereby, the air discharged from the first air duct 11 and the air discharged from the second air duct 11 The air discharged from the air duct 12 is blown to the left and right sides of the internal unit of the air conditioner. The user feels comfortable. Of course, the air outlet of the first air duct 11 and the air outlet of the second air duct 12 may also be formed on the left and right sides of the front side wall of the housing 1 respectively.

2, the first air duct 11 and the second air duct 12 are each provided with a separate humidification module 5, and the humidification module 5 is used to increase the humidity of the air flowing through the air duct. As a result, the humidification module 5 can increase the humidity of the air discharged into the room, improve the problem of dry indoor air caused by the heating of the air conditioner, and improve the comfort of the user. Moreover, when the air discharged from the air outlet of the first air duct 11 and the air outlet of the second air duct 12 is blown to different areas of the room, users in different areas of the room can feel the wind with a certain humidity. Conducive to improving the user's comfort experience.

In this embodiment, the humidification modules 5 respectively provided in the first air duct 11 and the second air duct 12 are configured to be controlled separately or in linkage control. Therefore, when the two humidification modules 5 are configured to be controlled separately, the air conditioner internal unit can flexibly discharge air with a certain humidity into the room, thereby meeting the user's requirements for humidity in different scenarios; when the two humidification modules When 5 is configured for linkage control, there is no need to control the two humidification modules 5 separately, the operation is simple, and the humidity of the indoor air can be changed in a balanced manner.

When the humidification modules 5 respectively provided in the first air duct 11 and the second air duct 12 are configured to be controlled separately, the control strategies of the two humidification modules 5 may be different.

In an example, the humidification module 5 of the first air duct 11 is configured to have a different operating state from the humidification module 5 of the second air duct 12. In other words, one of the two humidification modules 5 works to increase the humidity of the air flowing through the air duct where it is located, and the other stops working. Therefore, when the air discharged from the air outlet of the first air duct 11 and the air outlet of the second air duct 12 are respectively blown to the first area and the second area of the room, the above-mentioned control method can make the air with a certain humidity Blow separately to the first area or separately to the second area to specifically adjust the air humidity in a certain area to meet the needs of users in that area.

Illustratively, users located in the first area require indoor air to have a certain humidity, and users located in the second area (for example, patients with rheumatism, infants, etc.) require low humidity in the indoor air or when the indoor air is dry , The humidification module 5 in the first air duct 11 is configured for humidification, and the humidification module 5 in the second air duct 12 is configured to stop humidification, so as to meet the requirements of users in different regions.

In another example, the humidification module 5 of the first air duct 11 is configured to have a different humidification efficiency from the humidification module 5 of the second air duct 12. That is, the humidification amount of the humidification module 5 in the first air passage 11 to the air of the first air passage 11 and the humidification amount of the humidification module 5 in the second air passage 12 to the air of the second air passage 12 are different. As a result, the requirements of users in different areas for different humidity can be met.

For example, when the user (for example, young people) in the first area has a requirement of 60% for air humidity, and the user (for example, the elderly) in the second area has a requirement for air humidity of 20%, the first air duct 11 is configured. The humidification module 5 in the second air duct 12 has a higher humidification efficiency for the air than the humidification module 5 in the second air duct 12 has a higher humidification efficiency for the air.

Specifically, the humidification module 5 may include a water container, an air duct, and an ultrasonic atomizing sheet. The water container is used to contain water, and the ultrasonic atomizing sheet is arranged in the water container to generate vapor from the water in the water container. An air supply port is arranged on the upper part, the air inlet end of the air guide tube is connected with the air supply port, and the air outlet end of the air guide tube is connected with the air duct. When the internal unit of the air conditioner is working, the ultrasonic atomizing film operates to make the water in the water container produce water vapor. The water vapor enters the air duct through the air supply port and the air inlet end of the air duct in turn, and then flows from the air outlet end of the air duct to the air duct. , It merges with the air in the air duct to increase the humidity of the air in the air duct.

Fig. 3 is a front view of the humidifying module in the double-through air conditioner internal unit provided by an embodiment of the present invention, and Fig. 4 is a schematic structural diagram of the humidifying module in the double-through flow air conditioner internal unit provided by an embodiment of the present invention. Or, as shown in FIGS. 3 and 4, the humidification module 5 may also include a water container 51, a water pump 52, a water supply pipe 53, and a humidification member 54, where the water container 51 is used to contain water, and the water inlet of the water pump 52 is in communication with the water container 51 The outlet pipe of the water pump 52 communicates with one end of the water supply pipe 53, and the other end of the water supply pipe 53 communicates with the humidifying element 54 which is configured to allow air to pass through. Therefore, compared with the previous implementation, it is beneficial to prevent the formed water vapor from flowing in the housing 1 and affecting the electrical performance of other components.

In this embodiment, the dual tubular air conditioner internal unit 10 further includes a controller, which is electrically connected to the water pump 52 of the humidification module 5. The controller is used to control the power of the water pump 52 of the humidification module 5 in the two air ducts, so as to achieve linkage Control or separate control. Specifically, the controller controls the powers of the water pumps 52 of the humidification modules 5 in the two air ducts to be different, so that the two humidification modules 5 have different humidification efficiencies.

It is worth noting that the humidification module 5 provided in the first air duct 11 and the humidification module 5 provided in the second air duct 12 may share a water container 51. As a result, the number of water containers 51 used is reduced, and the overall air conditioner internal unit is simpler. Among them, the water container 51 can be a water tank, which can be installed at the bottom of the casing 1 or other positions, as long as water can be injected into the water tank from the outside of the casing 1, so as to prevent the water in the water tank from being consumed and the humidifying element 54 cannot be refilled. , To ensure that the humidifier 54 can work effectively. In other examples, the water container 51 may also be a water receiving pan, which is arranged at the bottom of the heat exchanger 2, and the water receiving pan is used to receive the condensed water on the heat exchanger 2. As a result, condensed water can be recycled and resources can be saved.

The humidifying element 54 includes a support frame and a water absorption part connected to the support frame, and the water absorption part communicates with the other end of the water supply pipe 53 to increase the humidity of the air passing through the water absorption part. Wherein, the supporting frame can be made of metal material or plastic material, and is used to support the water absorption part so as to improve the strength of the humidifying member 54. The water absorbing part may be a sponge block, and a socket is formed on the sponge block, and the water supply pipe 53 is inserted into the socket to introduce water into the sponge block to make it wet. Here, the water absorption part and the support frame can be connected by bonding, or can be connected by detachable means such as plug-in connection, which is not limited in this embodiment.

Wherein, the humidifying element 54 may be installed between the cross flow fan 3 and the air outlet of the air duct. When the air conditioner starts, the cross flow fan 3 runs, and the air in the external environment enters the first air duct 11 and the second air duct 12 under the action of the cross flow fan 3, first passes through the heat exchanger 2 to exchange heat, and then passes through the humidification module 5 Humidification. Or, as shown in FIG. 2, the humidifying element 54 can also be installed between the air inlet of the air duct and the heat exchanger 2. In this example, the air in the external environment is first humidified by the humidification module 5, and then heat exchange with the heat exchanger 2 is performed. Therefore, the structure between the heat exchanger 2, the cross-flow fan 3 and the air outlet of the air duct is usually relatively compact. With this arrangement, the installation space of the humidifying element 54 is large, which is convenient for installation.

Moreover, the humidifying element 54 is arranged close to the air inlet of the air duct, so that the humidifying element 54 can be disassembled, and then the humidifying element 54 can be repaired and replaced, so that the humidifying element 54 can work effectively. Specifically, an air inlet grille is detachably connected to the rear side wall of the casing 1, and the humidifying element 54 is detachably connected to the inner side wall of the air inlet grille facing the inside of the casing 1. When it needs to be replaced, first remove the inlet grille from the housing 1, and then separate the humidifying element 54 and the inlet grille.

In addition, the controller may also be electrically connected to the cross flow fan 3 provided in the first air duct 11 and the second air duct 12 to control the power of the cross flow fan 3. Therefore, the controller can control the air flow of the air duct by controlling the power of the cross flow fan 3, and thus can control the humidification rate.

Fig. 5 is a working principle diagram of the cross-flow fans having different operating powers in the first air duct and the second air duct of the internal unit of the dual-tubular flow air conditioner provided by the embodiment of the present invention. The controller's control strategy for the two cross flow fans 3 can be divided into the following situations: The first is that the controller controls the cross flow fan 3 in the first air duct 11 and the cross flow fan 3 in the second air duct 12 The operating state is different, so that one of the cross-flow fans 3 stops working, so that the air with a certain humidity is blown to the first area alone or to the second area alone; the second is that the controller controls the first air duct 11 The cross flow fan 3 and the cross flow fan 3 in the second air duct 12 have the same operating power to humidify the first area and the second area at the same time, and make the humidity of the first area and the second area the same; as shown in Figure 5 As shown, the third type is that the controller controls the cross flow fan 3 in the first air duct 11 and the cross flow fan 3 in the second air duct 12 to have different operating powers, so that the The air volume of the humid air is different, so that the humidification volume of the first area and the second area are different, so as to meet the requirements of users in different areas for different humidity.

In addition, the controller is configured to control the water pump 52 of the humidification module 5 in the air duct to operate for a first preset time when the cross-flow fan 3 provided in each of the first air duct 11 and the second air duct 12 is operating, and then to control the water pump 52 stopped operation. Thus, while the cross flow fan 3 in the air duct is activated, the water pump 52 continues to supply water to the humidifying element 54 for a preset period of time, so that the humidifying element 54 is humidified, and then the humidity of the air flowing through the humidifying element 54 is increased.

Here, the first preset time can be freely set by the designer according to experience and actual needs, which is not limited in this embodiment. Preferably, the first preset time may be the time required for the water pump 52 to supply water to the humidifying element 54 and make it reach a saturated state. Therefore, there is no need to frequently supply water to the humidifying element 54.

Further, the air inlets of the first air duct 11 and the second air duct 12 are provided with humidity sensors, and the controller is electrically connected to the humidity sensor. The controller is used to control the humidity sensor to detect the air humidity in the external environment when the water pump 52 stops running, And when the air humidity does not reach the preset humidity, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds the preset humidity, the water pump 52 is controlled to stop operating for a second preset time. Among them, the preset humidity can be set by the user, so that the indoor air humidity meets the needs of the user; the second preset time can also be freely set by the designer according to experience and actual needs.

With the above settings, after the water pump 52 runs for the first preset time, the humidity of the indoor air is detected. If the indoor air humidity does not reach the preset humidity, the water pump 52 continues to supply water to the humidifying element 54 and then increasing the humidity of the air flowing through the humidifying element 54 If the indoor air humidity exceeds the preset humidity, the water pump 52 will stop supplying water to the humidifying element 54 to prevent the air humidity from increasing continuously, and then the indoor air humidity will gradually decrease to achieve the user’s satisfaction. Set humidity. In general, when the indoor air humidity of the double tubular air conditioner 10 detects that the humidity of the indoor air does not meet the requirements of the user, it automatically controls the humidification module 5 to adjust its humidification efficiency, so that the indoor air humidity reaches the user's satisfactory humidity, so as to improve the user's Comfortable experience and intelligent control is realized.

When the wind blown from the respective outlets of the first air duct 11 and the second air duct 12 is blown to different areas in the room, the air inlet part of the first air duct 11 and the second air duct 12 can be separated, and the first Separate humidity sensors are provided at the air inlets of the air duct 11 and the second air duct 12 respectively. The controller is used to control the humidity sensor in the first air duct 11 to detect the air humidity in the external environment when the water pump 52 paired with the humidifying element 54 in the first air duct 11 stops operating, and when the air humidity does not reach the first preset When the humidity is set, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds a first preset humidity, the water pump 52 is controlled to stop operating for a second preset time. The controller is used to control the humidity sensor in the second air duct 12 to detect the air humidity in the external environment when the water pump 52 paired with the humidifier 54 in the second air duct 12 stops operating, and when the air humidity does not reach the second preset When the humidity is set, the water pump 52 is controlled to operate, or when the air humidity reaches or exceeds a second preset humidity, the water pump 52 is controlled to stop operating for a second preset time.

The first preset humidity is the air humidity that is satisfactory to the user in the first area, and the second preset humidity is the air humidity that is satisfactory to the user in the second area. In this way, the air humidity in the first area and the second area respectively meet the requirements of users in the area, so as to meet the requirements of users in different areas for different humidity.

Of course, in some examples of the present invention, a separate wind deflector 6 is provided at the air outlets of the first air duct 11 and the second air duct 12 respectively. Therefore, the wind deflector 6 can be used to open and close the air outlet of the air duct, and can also be used to guide the flow direction of the air flowing out of the air outlet.

Wherein, the air guide plates 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately or in linkage control. When the two air deflectors 6 are configured for linkage control, the air outlet of the first air duct 11 and the air outlet of the second air duct 12 can be opened or closed at the same time, so that there is no need to separately control the two air deflectors 6 , Easy to operate. When the two air deflectors 6 are configured to be controlled separately, the air outlet of the first air duct 11 and/or the air outlet of the second air duct 12 can be opened and closed separately by controlling the two air deflectors 6 separately, and then Separately humidify the first zone and/or the second zone, so that the internal air conditioner is suitable for various scenarios.

The dual tubular air conditioner internal unit 10 may also include a driver, which is used to controllably drive the air deflector 6 to rotate to open and close the air outlet of the air duct. The number of drivers can be set to one, and the same driver can simultaneously control the respective air guide plates 6 of the first air duct 11 and the second air duct 12 to achieve linkage control. There may be two drivers, and the two drivers respectively drive the air deflector 6 in the first air duct 11 and the air deflector 6 in the second air duct 12 to move, so as to realize separate control. Among them, the driver can be a motor, an air cylinder, an oil cylinder, and so on.

Specifically, the wind deflector 6 is rotatably connected with the housing 1 through a rotating shaft, a driver is drivingly connected with the rotating shaft, and the driver drives the wind deflector 6 to rotate around the rotating shaft to open and close the air outlet. Optionally, the rotating shaft is arranged at one end of the wind deflector 6. Therefore, when the wind deflectors 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately, the opening of the wind deflectors 6 can be adjusted by adjusting the rotation angles of the two rotating shafts. The angle can then adjust the opening and closing degree of the air outlet of the air duct, so that the amount of humid air sent into the first area and the second area can be different, so as to meet the requirements of users in different areas for different humidity.

Preferably, the rotating shaft is arranged in the middle of the wind deflector 6. Therefore, when the air guide plates 6 respectively provided at the air outlets of the first air duct 11 and the second air duct 12 are configured to be controlled separately, not only the opening of the air outlet of the air duct can be adjusted by controlling the rotation angle of the rotating shaft. The degree of closure can also adjust the air supply area of the air outlet of the air duct, and then meet the needs of users for different air supply areas.

Of course, in some examples, the wind deflector 6 may also be a swing blade, and the user can change the angle of the wind deflector 6 by flipping the swing blade, thereby changing the air supply area of the air outlet and the degree of opening and closing of the air outlet.

This embodiment also provides an air conditioner. The air conditioner includes an air conditioner outer unit and the above-mentioned double tubular air conditioner inner unit 10. The air conditioner outer unit is connected to the double tubular air conditioner inner unit 10, The internal machine 10 transports the refrigerant, thereby realizing cooling and heating. Through the above arrangement, the air conditioner can increase the humidity of the air discharged into the room by using the humidification module 5, improve the problem of dry indoor air caused by the heating of the air conditioner, and improve the comfort of the user.
