Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a fresh air air conditioner and an air intake control method thereof. Background Art

[0002] In order to combine the air purification function with the indoor heating or cooling function and improve the indoor air comfort, a fresh air module is often added inside the cabinet air conditioner in the prior art.

[0003] Usually, the fresh air module needs to be configured with a separate motor and fan. This means that when adding a fresh air module to a conventional air conditioner, on the one hand, it is necessary to install motors, fans and other devices on the air conditioner, resulting in high costs for modifying or manufacturing the fresh air air conditioner, which is not conducive to its widespread promotion and application. On the other hand, in order to install components such as the motor and fan in the fresh air module inside the air conditioner, it is necessary to make major modifications to the structure of the air conditioner, which makes it difficult to modify or manufacture the fresh air air conditioner.

[0004] In addition, for ordinary users, due to the lack of professional air-conditioning technology and special parts, if they want to replace an ordinary air conditioner with an air conditioner with a fresh air function, they often need to replace the entire air-conditioning cabinet. However, the air-conditioning cabinet is expensive and the replacement cost is high, which greatly limits the user's choice.

[0005] Therefore, it is one of the technical problems that technical personnel in this field urgently need to solve to provide a fresh air air conditioner and an air intake control method thereof which has a simple overall structure and can achieve air purification, cooling and heating functions through simple modification on the basis of the existing air conditioner, so that ordinary users can achieve the fresh air function by separately installing a fresh air module. Summary of the invention

[0006] The present invention designs a fresh air air conditioner and an air intake control method thereof, so as to realize air purification, cooling and heating functions through simple modification on the basis of the existing air conditioner, so that ordinary users can realize the purpose of the fresh air function by separately installing a fresh air module.

[0007] In order to solve the above problems, the present invention discloses a fresh air air conditioner, comprising a main body and a fresh air module:

[0008] The main body is provided with an air inlet grille, and the gas outside the air inlet grille can enter the evaporator in the fresh air air conditioner through the air inlet grille;

[0009] The fresh air module can be detachably mounted on the air inlet grille, and the fresh air module includes an air inlet hood, which is arranged on the outside of the air inlet grille and forms a hollow air inlet cavity between the air inlet hood and the air inlet grille. A fresh air access pipe is provided on the air inlet hood, and both ends of the fresh air access pipe are respectively connected to the air inlet cavity and outdoor atmosphere. The outdoor atmosphere can enter the air inlet cavity through the fresh air access pipe, and then enter the evaporator in the fresh air air conditioner through the air inlet grille.

[0010] The fresh air air conditioner described in the present application forms an air inlet cavity connected to the air inlet grille on the outside of the main body by arranging an air inlet cover on the outside of the air inlet grille, and a fresh air access pipe that can be connected to the outdoor atmosphere is arranged on the air inlet cover, and the fresh air function of the fresh air air conditioner is realized through the fresh air access pipe. The fresh air module has a simple structure and can be realized by directly adding an air inlet cover on the outside of the air inlet grille. On the one hand, the fresh air module can directly use the air inlet grille and the motor, fan and other devices inside the main body to realize the fresh air intake, without the need to additionally install motors, fans and other devices on the main body, thereby reducing the manufacturing cost or modification cost of the fresh air air conditioner described in the present application; on the other hand, the fresh air module can be directly added to the outside of the air inlet grille, without any modification to the internal structure of the main body, thereby avoiding modification or manufacturing troubles of the fresh air air conditioner.

[0011] Furthermore, a plurality of indoor air inlets are arranged on the air inlet cover.

[0012] The indoor air inlet on the air inlet cover allows indoor air to enter the air inlet cavity through the indoor air inlet, and then enter the interior of the fresh air air conditioner. The provision of multiple indoor air inlets can also make the air intake mode of the fresh air air conditioner flexible and changeable.

[0013] Furthermore, the indoor air inlet and the fresh air inlet pipe are both provided with openable and closable covers.

[0014] The cover plate can be used to adjust the opening and closing state or opening and closing degree of the indoor air inlet and the fresh air inlet pipe, thereby adjusting the gas composition entering the fresh air air conditioner.

[0015] Furthermore, the fresh air air conditioner is provided with a driving motor connected to the cover plate, and the driving motor can drive the cover plate to rotate to open or close the indoor air inlet and the fresh air access pipe.

[0016] The provision of the driving motor makes the opening and closing control of the indoor air inlet and the fresh air intake pipe more convenient.

[0017] Furthermore, a fan for introducing fresh air is provided in the fresh air inlet pipe.

[0018] The air intake rate of the fresh air inlet pipe can be regulated by setting the fan.

[0019] Furthermore, the air inlet cover is detachably connected to the air inlet grille.

[0020] The connection between the air inlet cover and the air inlet grille is set to be a detachable connection, which is convenient for installing and disassembling the air inlet cover, and also convenient for cleaning the air inlet cover and the air inlet grille.

[0021] A fresh air air conditioner air intake control method is used to control the above-mentioned fresh air air conditioner, and the fresh air air conditioner air intake control method includes at least three modes: indoor gas circulation, outdoor fresh air circulation and internal and external circulation.

[0022] By setting up three modes of internal gas circulation, outdoor fresh air circulation and internal and external circulation, the fresh air air conditioner can meet a variety of air intake modes such as separate indoor air intake, separate outdoor air intake and simultaneous indoor and outdoor air intake. The fresh air air conditioner has the advantages of flexible and diverse air intake methods and can meet the various air intake needs of users.

[0023] Furthermore, when the fresh air air conditioner is operated in the indoor gas circulation mode, at least one indoor air inlet is opened and the fresh air access pipe is closed. At this time, the outdoor air cannot enter the air inlet cavity, while the indoor air can enter the air inlet cavity through the indoor air inlet.

[0024] By adjusting the opening and closing states of the indoor air inlet and the fresh air intake pipe, separate indoor air intake is achieved.

[0025] Furthermore, when the fresh air air conditioner is operated in the outdoor fresh air circulation mode, all indoor air inlets are closed and the fresh air access pipe is opened. At this time, the indoor air cannot enter the air inlet cavity, while the outdoor air can enter the air inlet cavity through the fresh air access pipe.

[0026] By adjusting the opening and closing states of the indoor air inlet and the fresh air intake pipe, separate outdoor air intake is achieved.

[0027] Furthermore, when the fresh air air conditioner is operated in the internal and external circulation mode, at least one indoor air inlet is opened and the fresh air access pipe is opened. At this time, the outdoor air can enter the air inlet cavity through the fresh air access pipe, and the indoor air can enter the air inlet cavity through the indoor air inlet.

[0028] By adjusting the opening and closing states of the indoor air inlet and the fresh air intake pipe, simultaneous indoor and outdoor air intake is achieved.

[0029] To sum up, the fresh air air conditioner and its air intake control method described in the present application not only have a simple structure and can be obtained through simple modification on the basis of the existing air conditioner, but also can realize a variety of air intake modes, have flexible and diverse air intake methods, and can meet the different needs of users.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 5 As shown, a fresh air air conditioner includes a main body 1 and a fresh air module:

[0040] The main body 1 is provided with an air inlet grille 11, and the gas outside the air inlet grille 11 can enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and is heated or cooled by the main body 1 before being output, so as to realize the heating or cooling function of the fresh air air conditioner;

[0041] The fresh air module is detachably mounted on the air inlet grille 11, and includes an air inlet hood 2, which is arranged on the outside of the air inlet grille 11, and forms a hollow air inlet cavity 21 between the air inlet hood 2 and the air inlet grille 11, and a fresh air access pipe 22 is provided on the air inlet hood 2, and both ends of the fresh air access pipe 22 are respectively connected with the air inlet cavity 21 and the outdoor atmosphere, and the outdoor atmosphere can enter the air inlet cavity 21 through the fresh air access pipe 22, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and be output after being heated or cooled by the main body 1, so as to realize the fresh air function of the fresh air air conditioner.

[0042] Specifically, the air inlet cover 2 is detachably mounted on the outside of the air inlet grille 11, and other components of the fresh air module, such as the fresh air inlet pipe 22, are detachably mounted on the air inlet cover 2. When an existing ordinary air conditioner is transformed into a fresh air air conditioner with a fresh air function, other components of the fresh air module can be integrated and mounted on the air inlet cover 2 first, and then the air inlet cover 2 can be mounted on the outside of the air inlet grille 11, which is simple and convenient to operate.

[0043] In the present application, the side of the air inlet grille 11 close to the main body 1 is referred to as the “inner side” of the air inlet grille 11 ; the side of the air inlet grille 11 away from the main body 1 is referred to as the “outer side” of the air inlet grille 11 .

[0044] The fresh air air conditioner described in the present application is provided with an air inlet hood 2 on the outer side of the air inlet grille 11, thereby forming an air inlet cavity 21 connected with the air inlet grille 11 on the outer side of the main body 1, and a fresh air inlet pipe 22 that can be connected with the outdoor atmosphere is provided on the air inlet hood 2, and the fresh air function of the fresh air air conditioner is realized through the fresh air inlet pipe 22.

[0045] The fresh air module has a simple structure and can be realized by directly adding an air inlet cover 2 on the outside of the air inlet grille 11. On the one hand, the fresh air module can directly use the air inlet grille 11 and the motor, fan and other devices inside the main body 1 to realize the fresh air intake, without the need to additionally install motors, fans and other devices on the main body 1, thereby reducing the manufacturing cost or modification cost of the fresh air air conditioner described in this application; on the other hand, the fresh air module can be directly added to the outside of the air inlet grille 11, without any modification to the internal structure of the main body 1, thereby avoiding the modification or manufacturing trouble of the fresh air air conditioner. Therefore, for ordinary users, the fresh air function can be realized by adding the fresh air module to an ordinary air conditioning cabinet, which is convenient, practical and low-cost.

[0046] As some embodiments of the present application, the air inlet cover 2 can completely cover the outer side of the air inlet grille 11 or partially cover it.

[0047] Specifically, when the air inlet cover 2 does not completely cover the outside of the air inlet grille 11, part of the air inlet grille 11 will be exposed outside the air inlet cover 2. When the fresh air air conditioner is started, indoor air can directly enter the fresh air air conditioner through the exposed area of ​​the air inlet grille 11; outdoor air can enter the air inlet cavity 21 through the fresh air access pipe 22, and then enter the fresh air air conditioner through the air inlet grille 11, thereby achieving the functions of air purification, cooling or heating.

[0048] When the air inlet cover 2 completely covers the outside of the air inlet grille 11, the air inlet grille 11 is completely wrapped by the air inlet cover 2. When the fresh air air conditioner is started, indoor air can enter the interior of the fresh air air conditioner through the indoor air inlet 23 provided on the air inlet grille 11; outdoor air can enter the air inlet cavity 21 through the fresh air access pipe 22, and then enter the interior of the fresh air air conditioner through the air inlet grille 11, thereby achieving the functions of air purification, cooling or heating.

[0049] Preferably, the air inlet cover 2 completely covers the outer side of the air inlet grille 11 , and a plurality of indoor air inlets 23 are provided on the air inlet cover 2 .

[0050] Furthermore, the air inlet cover 2 and the air inlet grille 11 can be detachably connected together by means of snap connection, hinge connection, screw connection, riveting, etc. In this way, the air inlet cover 2 can be easily assembled and disassembled, and during the operation of the air conditioner, the air inlet cover 2 and the air inlet grille 11, as the main air inlet components, are prone to dust accumulation, so it is convenient for users to clean the air inlet cover 2 and the air inlet grille 11.

[0051] Furthermore, both the indoor air inlet 23 and the fresh air inlet pipe 22 are provided with an openable and closable cover plate 25. When the cover plate 25 on the indoor air inlet 23 is opened, the indoor air inlet 23 corresponding thereto can be connected to the indoor atmosphere, and the indoor atmosphere can enter the interior of the fresh air air conditioner through the indoor air inlet 23; when the cover plate 25 on the indoor air inlet 23 is closed, the indoor air inlet 23 corresponding thereto is no longer connected to the indoor atmosphere, and the indoor atmosphere cannot enter the interior of the fresh air air conditioner through the indoor air inlet 23. When the cover plate 25 on the fresh air inlet pipe 22 is opened, the fresh air inlet pipe 22 is connected to the outdoor atmosphere, and the outdoor atmosphere can enter the air inlet cavity 21 through the fresh air inlet pipe 22, and then enter the interior of the fresh air air conditioner through the air inlet grille 11; when the cover plate 25 on the fresh air inlet pipe 22 is closed, the fresh air inlet pipe 22 is not connected to the outdoor atmosphere, and the fresh air air conditioner stops the fresh air function.

[0052] As some embodiments of the present application, the indoor air inlet 23 includes a first indoor air inlet 231 and a second indoor air inlet 232, and the cover plate 25 includes a first cover plate 251 disposed on the first indoor air inlet 231, a second cover plate 252 disposed on the second indoor air inlet 232, and a third cover plate disposed in the fresh air inlet pipe 22. By adjusting the opening and closing states of the first cover plate 251, the second cover plate 252, and the third cover plate, the on-off states of the first indoor air inlet 231, the second indoor air inlet 232, and the fresh air inlet pipe 22 can be adjusted.

[0053] Furthermore, by adjusting the opening and closing state or opening and closing degree of the indoor air inlet 23 and the fresh air access pipe 22, the indoor air flow entering the fresh air air conditioner can be adjusted, thereby adjusting the ratio of indoor air and outdoor air in the gas entering the fresh air air conditioner.

[0054] Furthermore, the fresh air air conditioner is provided with a driving motor connected to the cover plate 25 , and the driving motor can drive the cover plate 25 to rotate to open or close the indoor air inlet 23 and the fresh air access pipe 22 .

[0055] Preferably, the drive motor is connected to the control panel of the fresh air air conditioner, and the movement state of the drive motor can be controlled by the control panel, thereby controlling the opening and closing states of the indoor air inlet 23 and the fresh air access pipe 22, thereby realizing automatic control of the cover plate 25.

[0056] As some embodiments of the present application, the position of the fresh air inlet pipe 22 can be adjusted according to installation requirements. For example, the fresh air inlet pipe 22 can be located at the top, middle or bottom of the air inlet cover 2.

[0057] Furthermore, a fan for introducing fresh air is provided in the fresh air inlet pipe 22, and preferably, the fan is an axial flow fan.

[0058] Preferably, the fan is connected to a control panel of the fresh air air conditioner, and the movement state of the fan can be controlled by the control panel, thereby controlling the air intake rate of the fresh air access pipe 22.

[0059] Furthermore, a purification module 24 is disposed in the air inlet cavity 21 , and the purification module 24 can purify the gas entering the air inlet cavity 21 .

[0060] Preferably, the purification module 24 is arranged in a plate-like inclined manner in the air inlet cavity 21, and the internal space of the air inlet cavity 21 is divided into two parts, a first air inlet cavity 211 and a second air inlet cavity 212 by the purification module 24. The fresh air access pipe 22 and at least one indoor air inlet 23 are located in the first air inlet cavity 211, and the air inlet grille 11 and at least one indoor air inlet 23 are located in the second air inlet cavity 212.

[0061] Specifically, as some embodiments of the present application, the second indoor air inlet 232 and the fresh air access pipe 22 are located in the first air inlet cavity 211 , and the first indoor air inlet 231 and the air inlet grille 11 are located in the second air inlet cavity 212 . When the second indoor air inlet 232 is opened, the indoor air can enter the first air inlet cavity 211 through the second indoor air inlet 232, then pass through the purification module 24, enter the second air inlet cavity 212 after being purified by the purification module 24, and finally enter the interior of the fresh air air conditioner through the air inlet grille 11; when the fresh air access pipe 22 is opened, the outdoor air can enter the first air inlet cavity 211 through the fresh air access pipe 22, then pass through the purification module 24, enter the second air inlet cavity 212 after being purified by the purification module 24, and finally enter the interior of the fresh air air conditioner through the air inlet grille 11; when the first indoor air inlet 231 is opened, the indoor air can enter the second air inlet cavity 212 through the first indoor air inlet 231, and then enter the interior of the fresh air air conditioner through the air inlet grille 11.

[0062] Example 2

[0063] A fresh air air conditioner air intake control method is used to control the above-mentioned fresh air air conditioner, and the fresh air air conditioner air intake control method includes at least three modes: indoor gas circulation, outdoor fresh air circulation and internal and external circulation.

[0064] Specifically, when the fresh air air conditioner is operated in the indoor gas circulation mode, at least one of the indoor air inlets 23 is opened and the fresh air access pipe 22 is closed. At this time, the outdoor air cannot enter the air inlet cavity 21, while the indoor air can enter the air inlet cavity 21 through the indoor air inlet 23.

[0065] As some embodiments of the present application, when the fresh air air conditioner is operated in the indoor gas circulation mode, the first cover plate 251 and the second cover plate 252 are both opened, and the third cover plate is closed, so that the first indoor air inlet 231 and the second indoor air inlet 232 are opened, and the fresh air access pipe 22 is closed. At this time, the outdoor air cannot enter the air inlet cavity 21, while the indoor air can enter the second air inlet cavity 212 through the first indoor air inlet 231, and then enter the interior of the fresh air air conditioner through the air inlet grille 11; or enter the first air inlet cavity 211 through the second indoor air inlet 232, and then enter the second air inlet cavity 212 after passing through the purification module 24 and being purified by the purification module 24, and finally enter the interior of the fresh air air conditioner through the air inlet grille 11. It can be seen that by opening the second indoor air inlet 232, the fresh air air conditioner of the present application can also purify the indoor air when it is operated in the indoor gas circulation mode.

[0066] When the fresh air air conditioner is operated in the outdoor fresh air circulation mode, the indoor air inlet 23 is closed and the fresh air inlet pipe 22 is opened, and the indoor air cannot enter the air inlet cavity 21, while the outdoor air can enter the air inlet cavity 21 through the fresh air inlet pipe 22. At the same time, the outdoor air entering the air inlet cavity 21 through the fresh air inlet pipe 22 can also be purified by the purification module 24 when entering the interior of the fresh air air conditioner.

[0067] When the fresh air air conditioner is operated in the internal and external circulation mode, at least one of the indoor air inlets 23 is opened and the fresh air access pipe 22 is opened. At this time, the outdoor air can enter the air inlet cavity 21 through the fresh air access pipe 22, and the indoor air can enter the air inlet cavity 21 through the indoor air inlet 23.

[0068] As some embodiments of the present application, when the fresh air air conditioner is operated in the internal and external circulation mode, the second indoor air inlet 232 and the fresh air access pipe 22 are opened, and the outdoor air can enter the first air inlet cavity 211 through the fresh air access pipe 22, and the indoor air can enter the first air inlet cavity 211 through the second indoor air inlet 232, and then pass through the purification module 24, enter the second air inlet cavity 212 after being purified by the purification module 24, and finally enter the interior of the fresh air air conditioner through the air inlet grille 11. At this time, the indoor and outdoor air entering the fresh air air conditioner will both be purified by the purification module 24.

[0069] Preferably, in the various air intake modes mentioned above, when the fresh air inlet pipe 22 is opened, the fan is also turned on synchronously to transport outdoor air into the air intake cavity 21 .

[0070] To sum up, it is not difficult to conclude that the fresh air air conditioner and its air intake control method described in the present application not only have a simple structure and can be obtained through simple modification on the basis of the existing air conditioner, but also can realize a variety of air intake modes, and have the advantages of flexible and diverse air intake methods and being able to meet the different needs of users.
