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 fresh air function with the indoor heating or cooling function and improve the indoor air comfort, in the prior art, a fresh air module is often added to the interior of an ordinary split air conditioner, such as a cabinet air conditioner.

[0003] Usually, when adding a fresh air module to a conventional air conditioner, on the one hand, it is necessary to add a fresh air inlet duct, install a motor, fan and other devices in the air conditioner, which leads to high cost for modification or manufacturing of the fresh air air conditioner, which is not conducive to its wide promotion and application; on the other hand, in order to install components such as the motor, fan and fresh air inlet duct in the fresh air module inside the air conditioner, it is necessary to make major modifications to the internal structure of the air conditioner, which leads to trouble in modification or manufacturing of 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 a fresh air air conditioner with a fresh air function, they often need to replace the entire air conditioner indoor unit. However, the air conditioner indoor unit, especially the cabinet air conditioner indoor unit, 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 need to solve urgently to provide a fresh air air conditioner and an air intake control method thereof which has a simple overall structure and can realize fresh air intake, cooling and heating functions through simple modification on the basis of the existing ordinary air conditioner, so that ordinary users can realize the fresh air function by separately adding a fresh air module on the basis of the existing ordinary air conditioner. 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 fresh air intake, cooling and heating functions through simple modification on the basis of the existing air conditioner, so that ordinary users can achieve 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 an air conditioner body and a fresh air module:

[0008] The air conditioner 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, and is heated or cooled by the air conditioner body before being output;

[0009] The fresh air module includes a shielding door and a fresh air inlet pipe. The shielding door can be opened and closed on the outside of the air inlet grille. When the shielding door is in an open state, the outside of the air inlet grille is connected with the indoor air; when the shielding door is in a closed state, the passage between the outside of the air inlet grille and the indoor air is blocked; one end of the fresh air inlet pipe is connected with the outside of the air inlet grille, and the other end extends to the outside of the room and is connected with the outdoor atmosphere. The outdoor atmosphere can enter the evaporator in the fresh air air conditioner through the fresh air inlet pipe and the air inlet grille in turn.

[0010] The fresh air air conditioner of the present application is provided with a shielding door on the outside of the air inlet grille, and the opening and closing of the shielding door realizes the regulation of the connection state between the air inlet grille and the indoor atmosphere, and a fresh air access pipe that can be connected to the outdoor atmosphere is provided on the outside of the air inlet grille, and the fresh air function of the fresh air air conditioner is realized through the fresh air access pipe. The structure of the fresh air module is simple, and it can be realized by directly adding a shielding door and a fresh air access pipe 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, and there is no need to add additional motors, fans and other devices on the air conditioner body, thereby reducing the manufacturing cost or modification cost of the fresh air air conditioner of the present application; on the other hand, the fresh air module can directly use the air inlet grille to transport fresh air into the air conditioner, avoiding the need to separately add a fresh air inlet on the fresh air air conditioner; in addition, the fresh air module can be directly added to the outside of the air inlet grille, and there is no need to make any modification to the internal structure of the air conditioner body, thereby avoiding the modification or manufacturing trouble of the fresh air air conditioner.

[0011] Furthermore, the shielding door is slidably arranged on the outer side of the air inlet grille.

[0012] The shielding door is slidably arranged on the outer side of the air inlet grille, so that the shielding door can be opened and closed conveniently, and the on-off state switching of the passage between the air inlet grille and the indoor atmosphere can be realized quickly.

[0013] Furthermore, the shielding door is rotatably arranged on the outer side of the air inlet grille.

[0014] The shielding door is rotatably arranged outside the air inlet grille, so that the shielding door can be opened and closed conveniently, and the on-off state of the passage between the air inlet grille and the indoor atmosphere can be quickly switched. At the same time, more options are provided for the setting of the shielding door.

[0015] Furthermore, the fresh air module also includes an air inlet cover, which is arranged on the outside of the air inlet grille, forming an air inlet cavity between the air inlet cover and the air inlet grille, and the shielding door and the fresh air access pipe are installed on the air inlet cover.

[0016] By setting the air inlet cover, the shielding door and the fresh air access pipe can be integrated on the air inlet cover first, and then the various components in the fresh air module can be organically combined into a whole. When converting an ordinary air conditioner into a fresh air air conditioner, the user only needs to purchase the above-mentioned fresh air module and install it on the air inlet grille of the ordinary air conditioner. Not only is the conversion process simple and easy to operate, but it is also low-cost and easy to implement. In addition, by setting the air inlet cover, an air inlet cavity can be formed on the outside of the air inlet grille. Through the air inlet cavity, indoor gas or outdoor fresh air can be first gathered in the air inlet cavity, and then transported to the inside of the air conditioner through the air inlet grille, which can effectively optimize the air intake effect.

[0017] Furthermore, the fresh air module is detachably mounted on the outside of the air inlet grille.

[0018] The fresh air module is detachably mounted on the air conditioner body, so that the user can complete the transformation of an ordinary air conditioner by simply installing the fresh air module on the outside of the air inlet grille. This is not only simple and easy to operate, but also low-cost and easy to implement.

[0019] Furthermore, the shielding door and the fresh air inlet pipe are installed on the air inlet cover, the fresh air inlet pipe is located at the top, bottom or both sides of the air inlet cover, and the air inlet cover is detachably installed on the outside of the air inlet grille.

[0020] The user can simply install an air inlet cover with a shielding door and a fresh air inlet pipe on the outside of the air inlet grille to achieve the purpose of adding a fresh air module, which is simple and easy to operate. In addition, the fresh air module can be easily disassembled and assembled, and during the operation of the air conditioner, the air inlet cover and the air inlet grille are the main air inlet components, which are prone to dust accumulation, so it is convenient for the user to clean the air inlet cover and the air inlet grille.

[0021] Furthermore, the shielding door is a sliding door arranged on the air inlet cover, and slideways are respectively arranged on the upper and lower sides of the air inlet cover, and the sliding door is slidably installed on the air inlet cover through the slideways.

[0022] The sliding installation of the sliding door can be realized by arranging a slideway on the air inlet cover, which is not only simple in structure and easy to realize, but also convenient to open and close and easy to operate. At the same time, it avoids the necessary modification of the air inlet grille structure when the sliding door is directly installed on the air inlet grille.

[0023] Furthermore, the shielding door is a revolving door arranged on the air inlet cover, and the revolving door is rotated to open toward a side away from the air inlet grille, so that the outer side of the air inlet grille can be connected with the indoor air.

[0024] The revolving door is arranged on the air inlet cover, which not only realizes the rotatable installation of the revolving door, but also has a simple structure and is easy to realize; it is convenient to open and close and easy to operate. At the same time, it avoids the necessary modification of the air inlet grille structure when the revolving door is directly installed on the air inlet grille.

[0025] Furthermore, an openable and closable cover plate and / or a fan for introducing fresh air is arranged in the fresh air inlet pipe, and the fan is an axial flow fan.

[0026] The cover plate can be used to adjust the opening and closing state or opening and closing degree of the fresh air inlet pipe, thereby adjusting the gas composition entering the fresh air air conditioner; the air intake rate of the fresh air inlet pipe can be regulated by setting the fan.

DETAILED DESCRIPTION

[0045] 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.

[0046] Example 1

[0047] like Figures 1 to 11 As shown, a fresh air air conditioner includes an air conditioner body 1 and a fresh air module:

[0048] The air conditioner 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 air conditioner body 1 and then output, so as to realize the heating or cooling function of the fresh air air conditioner;

[0049] The fresh air module includes a shielding door 3 and a fresh air inlet pipe 4, wherein the shielding door 3 is openably arranged on the outside of the air inlet grille 11, and when the shielding door 3 is in an open state, the outside of the air inlet grille 11 is connected with the indoor air, and the indoor air can flow to the outside of the air inlet grille 11 through the shielding door 3, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and be heated or cooled by the air conditioner body 1 before being output; when the shielding door 3 is in a closed state, the outside of the air inlet grille 11 is not connected with the indoor air, and the indoor air cannot enter the interior of the air conditioner body 1; one end of the fresh air inlet pipe 4 is connected with the outside of the air inlet grille 11, and the other end extends outdoors and is connected with the outdoor atmosphere, so that the outdoor atmosphere can flow to the outside of the air inlet grille 11 through the fresh air inlet pipe 4, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and be heated or cooled by the air conditioner body 1 before being output, so as to realize the fresh air function of the fresh air air conditioning system.

[0050] In the present application, the side of the air inlet grille 11 close to the air conditioner body 1 is called the "inner side" of the air inlet grille 11; the side of the air inlet grille 11 away from the air conditioner body 1 is called the "outer side" of the air inlet grille 11.

[0051] The fresh air air conditioner described in the present application is provided with a shielding door 3 on the outer side of the air inlet grille 11, and the connection state between the air inlet grille 11 and the indoor atmosphere is regulated by opening and closing the shielding door 3. A fresh air inlet pipe 4 that can be connected with the outdoor atmosphere is provided on the outer side of the air inlet grille 11, and the fresh air function of the fresh air air conditioner is realized through the fresh air inlet pipe 4.

[0052] The structure of the fresh air module is simple, and can be realized by directly adding a shielding door 3 and a fresh air access pipe 4 to 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 air conditioner body 1 to realize the fresh air intake, and there is no need to add additional motors, fans and other devices on the air conditioner body 1, which reduces 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 directly use the air inlet grille 11 to transport fresh air into the air conditioner, avoiding the need to add a fresh air inlet separately to the fresh air air conditioner; in addition, the fresh air module can be directly added to the outside of the air inlet grille 11, and there is no need to make any modification to the internal structure of the air conditioner body 1, 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 the indoor unit of an ordinary air conditioner, which is convenient, practical and low in cost.

[0053] Furthermore, the shielding door 3 and the fresh air inlet pipe 4 are installed on the outside of the air inlet grille 11 through the air inlet cover 2.

[0054] Specifically, the air inlet cover 2 is a hollow shell that is arranged outside the air inlet grille 11. The air inlet cover 2 can completely cover the outside of the air inlet grille 11. The air inlet cavity 21 is formed between the air inlet cover 2 and the air inlet grille 11 by the air inlet cover 2. The shielding door 3 can be installed on the air inlet cover 2 in an openable and closable manner. One end of the fresh air inlet pipe 4 is inserted into the air inlet cover 2 and communicated with the air inlet cavity 21, thereby realizing its communication with the outside of the air inlet grille 11. The other end of the fresh air inlet pipe 4 extends to the outside to realize its communication with the external atmosphere. When the shielding door 3 is in a closed state, the air inlet cavity 21 cannot be communicated with the indoor atmosphere. When the shielding door 3 is in an open state, the air inlet cavity 21 can be communicated with the indoor atmosphere, thereby enabling the air inlet grille 11 to be communicated with the indoor atmosphere.

[0055] Furthermore, the fresh air module is detachably mounted on the outer side of the air inlet grille 11 .

[0056] Preferably, the fresh air module includes a shielding door 3, a fresh air access pipe 4 and an air inlet cover 2, wherein the shielding door 3 and the fresh air access pipe 4 are detachably mounted on the air inlet cover 2, and the air inlet cover 2 is detachably mounted on the outside of the air inlet grille 11. The air inlet cover 2 integrates the components of the fresh air module and detachably mounts them on the air conditioner body 1, so that the user can simply install the shielding door 3, the fresh air access pipe 4 and the air inlet cover 2 on the outside of the air inlet grille 11 to achieve the purpose of adding a fresh air module, which is not only simple and easy to operate, but also low in cost and easy to implement. In addition, the fresh air module can be easily disassembled and assembled, and during the operation of the air conditioner, the air inlet cover 2 and the air inlet grille 11 are the main air inlet components, which are easy to accumulate dust, so it is convenient for the user to clean the air inlet cover 2 and the air inlet grille 11.

[0057] As some embodiments of the present application, the air inlet cover 2 can be detachably connected to the air inlet grille 11 by means of snap connection, screw connection, riveting, etc.

[0058] As some embodiments of the present application, the fresh air inlet pipe 4 can be detachably connected to the air inlet cover 2 by means of snap connection, threaded connection, riveting, bolting, etc.

[0059] Furthermore, the shielding door 3 is slidably or rotatably arranged on the air inlet cover 2 .

[0060] Specifically, when the shielding door 3 is slidably arranged on the air inlet cover 2, as shown in FIG. Figures 1 to 7 As shown, the shielding door 3 is a sliding door 31 slidably mounted on the air inlet cover 2 , and slideways 32 are respectively provided on the upper and lower sides of the air inlet cover 2 , and the sliding door 31 is slidably mounted on the air inlet cover 2 through the slideways 32 .

[0061] Preferably, the fresh air module further includes a motor capable of driving the sliding door 31 to slide and a controller for controlling the working state of the motor. When the controller controls the motor to rotate forward, the sliding door 31 can slide open driven by the motor, so that the air inlet grille 11 is exposed and can be connected to the indoor atmosphere; when the controller controls the motor to rotate reversely, the sliding door 31 can slide closed driven by the motor, so that the air inlet grille 11 is enclosed in the air inlet cover 2 and can no longer be connected to the indoor atmosphere. Through the setting of the controller, the automatic opening and closing of the sliding door 31 is realized, and the automation degree of the fresh air module is improved.

[0062] As some embodiments of the present application, the sliding door 31 is a separate sliding door arranged on the air inlet cover 2, and the shielding door 3 is opened and closed by sliding the sliding door 31 in the horizontal direction.

[0063] As some embodiments of the present application, the sliding doors 31 are two sliding doors arranged on the air inlet cover 2, such as Figure 2 and 7 As shown, the sliding door 31 includes a first sliding door 311 and a second sliding door 312, wherein the first sliding door 311 can slide open to a side away from the second sliding door 312 to connect the air inlet grille 11 with the indoor atmosphere; the second sliding door 312 can slide open to a side away from the first sliding door 311 to connect the air inlet grille 11 with the indoor atmosphere. Preferably, the first sliding door 311 and the second sliding door 312 respectively have a motor capable of driving the sliding thereof and a controller for controlling the working state of the motor.

[0064] In addition, when the shielding door 3 is rotatably arranged on the air inlet cover 2, as shown in FIG. Figures 8 to 11 As shown, the shielding door 3 is a revolving door 33 rotatably arranged on the air inlet cover 2. By rotating and opening the revolving door 33 toward the side away from the air inlet grille 11, the air inlet grille 11 can be exposed so that it can be connected to the indoor atmosphere; conversely, by rotating and closing the revolving door 33 toward the side close to the air inlet grille 11, the air inlet grille 11 can be safely enclosed in the air inlet cover 2 so that it cannot be connected to the indoor atmosphere.

[0065] Furthermore, the rotating door 33 is rotatably mounted on the air inlet cover 2 by means of hinges, pivots, etc.

[0066] As some embodiments of the present application, the revolving door 33 may be a single revolving door rotatably arranged on the air inlet cover 2, or may be a plurality of revolving doors installed in parallel on the air inlet cover 2. Preferably, the revolving door 33 includes a first revolving door 331 and a second revolving door 332 relatively installed on both sides of the air inlet cover 2. By rotating the first revolving door 331 and / or the second revolving door 332, the air inlet grille 11 can be exposed so that it can be connected to the indoor atmosphere.

[0067] Furthermore, a rain cover 41 is provided at the end of the fresh air inlet pipe 4 located outdoors. The rain cover 41 is provided on the upper side of the end of the fresh air inlet pipe 4 to prevent rainwater and the like from entering the fresh air inlet pipe 4 .

[0068] Furthermore, an openable and closable cover is provided in the fresh air inlet pipe 4. When the cover is opened, the fresh air inlet pipe 4 is connected with the outdoor atmosphere, and the outdoor atmosphere can enter the air inlet cavity 21 through the fresh air inlet pipe 4, and then enter the interior of the fresh air air conditioner through the air inlet grille 11; when the cover on the fresh air inlet pipe 4 is closed, the fresh air inlet pipe 4 is not connected with the outdoor atmosphere, and the fresh air air conditioner stops the fresh air function.

[0069] 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 fresh air inlet pipe 4.

[0070] Preferably, the driving motor has a control panel capable of controlling its working state, and the operating state of the driving motor can be controlled by the control panel, thereby controlling the opening and closing state of the fresh air inlet pipe 4, thereby realizing automatic control of the cover plate.

[0071] Furthermore, the opening and closing degree of the cover plate can be adjusted by the control panel to adjust the air flow in the fresh air inlet pipe 4.

[0072] Furthermore, by adjusting the opening and closing state or opening and closing degree of the shielding door 3 and the fresh air inlet pipe 4, 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.

[0073] As some embodiments of the present application, the position of the fresh air inlet pipe 4 can be adjusted according to installation requirements, such as the fresh air inlet pipe 4 can be located at the top, both sides or bottom of the air inlet cover 2. Preferably, the fresh air inlet pipe 4 is installed at the bottom of the air inlet cover 2.

[0074] Furthermore, a fan for introducing fresh air is provided in the fresh air inlet pipe 4. Preferably, the fan is an axial flow fan. By adjusting the operating state of the fan, the air intake rate of the fresh air inlet pipe 4 can be controlled.

[0075] Example 2

[0076] 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 two modes: indoor gas circulation and outdoor fresh air circulation.

[0077] Specifically, when the fresh air air conditioner is operated in the indoor gas circulation mode, the shielding door 3 is opened and the fresh air access pipe 4 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 shielding door 3, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and is heated or cooled by the air conditioner body 1 before being output.

[0078] As some embodiments of the present application, Fig.10 As shown, when the fresh air air conditioner is operated in the indoor gas circulation mode, the first rotating door 331 rotates and opens to the side away from the air inlet grille 11, partially exposing the air inlet grille 11 so that it can be directly connected to the indoor atmosphere. At this time, the indoor atmosphere will be able to enter the air inlet cavity 21 through the first rotating door 331, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and be heated or cooled by the air conditioner body 1 before being output.

[0079] When the fresh air air conditioner is operated in the outdoor fresh air circulation mode, the shielding door 3 is closed and the fresh air access pipe 4 is opened. At this time, 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 access pipe 4, and then enter the evaporator in the fresh air air conditioner through the air inlet grille 11, and is heated or cooled by the air conditioner body 1 and then output.

[0080] Preferably, in the various air intake modes mentioned above, when the fresh air inlet pipe 4 is opened, the fan is also turned on synchronously to transport outdoor air into the air intake cavity 21 .

[0081] To sum up, the fresh air air conditioner and its air intake control method described in the present application not only have the advantages of simple structure, but also can be obtained through simple modification on the basis of the existing air conditioner, without any changes to the internal structure of the original air conditioner indoor unit; it can also realize multiple air intake modes, and has the advantages of flexible and diverse air intake methods and can meet the different needs of users.
