Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a control method for an air conditioning device with fresh air and heat exchange functions. Background Technology

[0002] Currently, users' demands for air conditioning have become more diversified, going beyond simply providing cooling and heating. Indoor air quality is receiving increasing attention, making fresh air functionality an essential feature of indoor air conditioning. Most wall-mounted air conditioners are integrated with both fresh air and heat exchange functions. However, due to limitations in size and noise, the fresh air volume is significantly restricted, resulting in a low volume. To address this issue, existing technologies typically employ a split-type fresh air module and heat exchange air conditioner. The fresh air module is installed at one end of the heat exchange air conditioner. When used alone, the fresh air module provides a relatively large volume of fresh air; however, because its outlet is fixed, the fresh air can only be expelled upwards. The fresh air mixes with indoor air before being drawn in by the air conditioner for heat exchange. During this process, a large amount of fresh air is not drawn in by the air conditioner, resulting in a low volume of fresh air participating in the heat exchange process. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a control method for an air conditioning device with fresh air and heat exchange functions that overcomes or at least partially solves the above problems, so as to increase the fresh air volume participating in heat exchange.

[0004] Specifically, the present invention provides a control method for an air conditioning device with fresh air and heat exchange functions. The air conditioning device includes a fresh air section capable of blowing out fresh air and a heat exchange section capable of blowing out heat exchange airflow. A heat exchange air inlet is provided on the upper surface of the heat exchange section. The fresh air section includes a fresh air module. The fresh air module is disposed at one end of the heat exchange section. The outlet direction and height of the fresh air outlet of the fresh air module are adjustable, allowing it to be in an initial position horizontally forward and lower than the heat exchange air inlet, and to move to a heat exchange position horizontally above the heat exchange air inlet. The control method for the air conditioning device includes:

[0005] In response to the activation of the fresh air function, it is determined whether the temperature difference between the outdoor air and the indoor air is within the standard deviation value. If so, fresh air is directly discharged from the fresh air outlet; otherwise, the fresh air outlet is moved to the heat exchange position and fresh air is discharged from the fresh air outlet at the same time.

[0006] Optionally, the control method further includes:

[0007] The system determines whether to activate the fresh air function based on indoor environmental parameters; if the indoor environmental parameters are worse than preset values, the fresh air function is activated.

[0008] Optionally, the indoor environmental parameters include carbon dioxide concentration and / or PM2.5 values.

[0009] Optionally, if the indoor environmental parameters are worse than preset parameter values, the indicator light on the display panel will display a first preset color; and / or, the mobile app will prompt poor air quality.

[0010] If the indoor environmental parameters are better than the preset parameter values, the indicator light on the display panel will show the second preset color; and / or, the mobile APP will indicate that the air quality is good.

[0011] Optionally, the heat exchange unit and the fresh air unit are separate structures, and the fresh air unit and the heat exchange unit transmit information to each other through a wireless transmission device or a wired transmission device. The heat exchange unit is the indoor unit of an air conditioner.

[0012] In response to the air conditioner being turned on, the fresh air module enters standby mode.

[0013] Optionally, if the indoor environmental parameters are better than preset parameter values, the fresh air module remains in standby mode.

[0014] Optionally, the fresh air module includes:

[0015] The fixed part has a fresh air inlet;

[0016] An air outlet has the fresh air outlet, which discharges air horizontally. The fresh air outlet is connected to the fresh air inlet. The air outlet is mounted on the fixed part in a raised and rotatable manner so that the direction and height of the fresh air outlet are adjustable.

[0017] Optionally, a notch is provided at the junction of the front surface and the upper surface of the fixing part, and the air outlet is installed at the notch; in the initial position, the air outlet is not higher than the upper surface of the fixing part, and the air outlet does not protrude forward from the front surface of the fixing part.

[0018] Optionally, the air outlet includes:

[0019] A vertical segment that extends from bottom to top;

[0020] A horizontal section extends horizontally from the upper end of the vertical section, and the fresh air outlet is located at the end of the horizontal section away from the vertical section;

[0021] The air outlet is mounted on the fixed part via a mounting base. The mounting base is a cylindrical structure with a guide rail on its outer periphery. The vertical section of the air outlet is fitted onto the mounting base and can move along the guide rail to rise and fall during rotation.

[0022] Optionally, the upper surface of the guide rail is a bent and extended track surface, and the lower end face of the vertical section contacts the upper surface of the track surface so that it can rise or fall along the track surface during rotation; the lower end face of the vertical section is adapted to the upper surface of the track surface so that it contacts the track surface in the initial position and rises along the track surface when rotating from the initial position.

[0023] The track surface includes a vertical surface, a first horizontal surface, an inclined surface, and a second horizontal surface that are sequentially distributed along the outer periphery of the mounting base. The distance between the vertical surface and the inclined surface gradually increases from bottom to top. The first horizontal surface extends from the bottom of the vertical surface to the bottom of the inclined surface, and the second horizontal surface extends from the top of the inclined surface to the top of the inclined surface.

[0024] The lower end face of the air outlet is adapted to the track surface of the guide rail. The lower end face of the air outlet has a vertical section, a planar section, and an inclined section. When the air outlet is in the initial position, the planar section of the lower end face of the air outlet is in contact with the first horizontal plane, the vertical section is in contact with the vertical plane, and the inclined section is in contact with the inclined plane. When the air outlet is facing the side of the fixing part, the planar section is in contact with the second horizontal plane.

[0025] In this invention, because the outlet direction and height of the air outlet structure are adjustable, when the temperature difference between outdoor and indoor air is large, and the user simultaneously uses the heat exchange unit and the fresh air module and requires fresh air to participate in the air conditioning heat exchange, the fresh air outlet of the fresh air module points to one end of the heat exchange unit, and this fresh air outlet is not lower than the heat exchange air inlet of the heat exchange unit, which can increase the amount of fresh air participating in heat exchange. When the temperature difference between outdoor and indoor air is small, the user can use only the fresh air function of the fresh air module, whose outlet outlet faces forward. This air outlet direction allows the fresh air to mix and exchange better with the indoor air, and also allows the user to better perceive the flow of fresh air. Therefore, this invention can both meet the optimal air outlet direction requirement when using the fresh air companion alone, and increase the amount of fresh air participating in heat exchange when heating is required.

[0026] Furthermore, the present invention determines whether to activate the fresh air function based on indoor environmental parameters, which can improve user comfort.

[0027] Furthermore, the fresh air module and heat exchange unit are connected via wireless or wired transmission devices.

[0028] Furthermore, in the initial position, the outlet of the fresh air module is not higher than the top of the fixed part, and the air outlet does not protrude forward from the front surface of the fixed part, which makes the appearance of the fresh air module more aesthetically pleasing.

[0029] Furthermore, by setting a guide rail, the air outlet can simultaneously change its angle and height while rotating along the guide rail; therefore, the present invention has the advantage of simple structure.

[0030] Furthermore, since the guide rail includes a vertical surface, which has a blocking and limiting function, it can prevent the air outlet from rotating in the reverse direction in the initial position; the horizontal surface has a supporting function for the vertical section, which can increase the structural stability of the air outlet.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] Figure 1 This is a first usage state diagram of an air conditioning device according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figure 2-11 This invention provides a control method for an air conditioning device with fresh air and heat exchange functions. The air conditioning device includes a fresh air section capable of blowing out fresh air and a heat exchange section 200 capable of blowing out heat exchange airflow. A heat exchange air inlet 210 is provided on the upper surface of the heat exchange section 200. The fresh air section includes a fresh air module 100. The fresh air module 100 is disposed at one end of the heat exchange section 200. The outlet direction and height of the fresh air outlet 121 of the fresh air module 100 are adjustable so that it can be in an initial position that is horizontally forward and lower than the height of the heat exchange air inlet, and can be moved to a heat exchange position that is horizontally above the heat exchange air inlet.

[0049] The control method of the air conditioning device includes: in response to the activation of the fresh air function, determining whether the temperature difference between the outdoor air and the indoor air is within the standard deviation value; if so, causing the fresh air outlet 121 to directly output fresh air; otherwise, causing the fresh air outlet 121 to move to the heat exchange position, and simultaneously causing the fresh air outlet 121 to output fresh air.

[0050] In this embodiment, the fresh air module 100 can operate solely for fresh air function or participate in heat exchange within the heat exchange unit 200. By adjusting the direction and height of the fresh air outlet 121, the fresh air outlet of the fresh air module can have an initial position and a position for heat exchange. When the fresh air outlet 121 is in the initial position, it blows fresh air towards the front, left front, or right front of the fixing part 110. When the fresh air outlet 121 is in the heat exchange position, it blows fresh air towards the left or right end of the heat exchange unit 200, and the fresh air outlet 121 is higher than the upper surface of the fixing part 110.

[0051] In this embodiment, because the outlet direction and height of the air outlet structure of the present invention are adjustable, when the temperature difference between outdoor and indoor air is large, and the user simultaneously uses the heat exchange unit and the fresh air module and requires fresh air to participate in the air conditioning heat exchange, the fresh air outlet of the fresh air module points to one end of the heat exchange unit, and this fresh air outlet is not lower than the heat exchange air inlet of the heat exchange unit, which can increase the amount of fresh air participating in heat exchange. When the temperature difference between outdoor and indoor air is small, the user can use only the fresh air function of the fresh air module, whose outlet outlet is forward-facing. This air outlet direction allows the fresh air to mix and exchange better with the indoor air, and also allows the user to better perceive the flow of fresh air. Therefore, the present invention can both meet the optimal air outlet direction requirement when using the fresh air function alone, and increase the amount of fresh air participating in heat exchange when heating the fresh air is required.

[0052] Specifically, the fresh air module 100 includes a first temperature sensor for detecting the temperature of the drawn-in outdoor air. The heat exchange unit 200 includes a second temperature sensor for detecting the indoor air temperature.

[0053] Furthermore, when the fresh air function is turned on, and the temperature difference between the outdoor air and the indoor air is within the standard deviation, the fresh air outlet maintains its initial position and directly outputs fresh air. Then, the user can manually adjust the direction of the fresh air outlet according to their needs.

[0054] In some optional embodiments of the present invention, the fresh air module 100 further includes an indoor environment detection device for detecting indoor environmental parameters. The control method further includes: determining whether to activate the fresh air function based on the indoor environmental parameters; if the indoor environmental parameters are worse than preset parameter values, then activating the fresh air function. In this embodiment, the present invention determines whether to activate the fresh air function based on indoor environmental parameters, which can improve user comfort.

[0055] Specifically, indoor environmental parameters include carbon dioxide concentration and / or PM2.5 levels. Indoor environmental monitoring devices include carbon dioxide sensors and / or PM2.5 sensors. The carbon dioxide sensor measures the indoor carbon dioxide concentration; the PM2.5 sensor measures the indoor PM2.5 level.

[0056] Furthermore, if the indoor environmental parameters are worse than preset values, the indicator light on the display panel will show a first preset color; and / or, the mobile app will indicate poor air quality. If the indoor environmental parameters are better than preset values, the indicator light on the display panel will show a second preset color; and / or, the mobile app will indicate good air quality. In this embodiment, the fresh air unit also includes a display panel that can display different colors. The display panel can use color changes to show the indoor air quality and the operating level of the fresh air unit.

[0057] For example, indoor environmental parameters include carbon dioxide concentration and PM2.5 levels. When both carbon dioxide concentration and PM2.5 levels are better than their respective preset parameters, the indicator light on the display panel turns green, and the mobile app indicates good air quality; the user can then decide whether to continue using the fresh air function based on their needs. When one or both of the carbon dioxide concentration and PM2.5 levels are worse than their respective preset parameters, the fresh air function is activated, the indicator light on the display panel turns yellow, and the mobile app indicates good air quality.

[0058] like Figure 1-4 As shown, in some optional embodiments of the present invention, the heat exchange unit 200 and the fresh air unit are separate structures, and the fresh air unit and the heat exchange unit 200 transmit information to each other through a wireless transmission device or a wired transmission device. The heat exchange unit 200 is the indoor unit of the air conditioner. In response to the air conditioner being turned on, the fresh air module enters standby mode.

[0059] Specifically, the fresh air module is powered by the air conditioner. When the air conditioner is turned on, the fresh air module automatically enters standby mode and can communicate with the air conditioner via a wireless or wired transmission device. The wireless transmission device can be a Bluetooth, WiFi, or infrared device; the wired transmission device is a data cable.

[0060] More preferably, if the indoor environmental parameters are better than preset parameter values, the fresh air module remains in standby mode. This setting avoids introducing outdoor air with poor air quality into the room, thereby further improving user comfort.

[0061] In some alternative embodiments of the present invention, the heat exchange section 200 and the fresh air section are integrally structured.

[0062] like Figure 1-11 As shown, in some optional embodiments of the present invention, the fresh air module 100 includes a fixing part 110 and an air outlet part 120. The fixing part 110 has a fresh air inlet; the air outlet part 120 has a fresh air outlet 121, which is connected to the fresh air inlet. The air outlet part 120 is movably disposed on the fixing part 110 so that the direction and height of the fresh air outlet 121 are adjustable.

[0063] In some alternative embodiments of the present invention, when the air outlet 120 is in the initial position, the fresh air outlet 121 faces forward, and the air outlet 120 is mounted on the fixed part 110 in a height-reducing and rotatable manner.

[0064] In this embodiment, on the one hand, in the initial position, the fresh air outlet 121 faces forward, which makes the appearance of the fresh air module 100 more aesthetically pleasing when it is closed. On the other hand, since the air outlet 120 is usually only used for fresh air function and only participates in heat exchange when heating fresh air, the air outlet 120 can meet the usage needs in the initial position when only the fresh air function is running, and there is no need to adjust the direction of the air outlet 120.

[0065] like Figure 1-6 As shown, in some optional embodiments of the present invention, a notch 111 is provided at the junction of the front surface and the upper surface of the fixing part 110, and the air outlet part 120 is installed at the notch 111. More preferably, the notch 111 is located on the left or right side of the fixing part.

[0066] Furthermore, in its initial position, the air outlet 120 is not higher than the upper surface of the fixing part 110, and the air outlet 120 does not protrude forward beyond the front surface of the fixing part 110. In other words, in its initial position, the air outlet 120 is lower than or flush with the upper surface of the fixing part 110, and is located inside or flush with the front surface of the fixing part 110. This arrangement makes the fresh air module 100 more aesthetically pleasing.

[0067] like Figure 1-2 As shown in Figure 5, preferably, when the air outlet 120 is in the initial position, the air outlet 120 is flush with the upper surface of the fixing part 110 and the air outlet 120 is flush with the front surface of the fixing part 110.

[0068] like Figure 3-4 As shown in Figures 6 and 7, more preferably, when the air outlet 120 participates in heat exchange, that is, when the air outlet 120 faces the left or right side of the fixed part, the fresh air outlet 121 extends outside the fixed part.

[0069] like Figure 9 As shown, in some optional embodiments of the present invention, the air outlet 120 includes a vertical section 124 and a horizontal section 122. The vertical section 124 extends from bottom to top; the horizontal section 122 extends horizontally from the upper end of the vertical section 124, and the fresh air outlet 121 is located at the end of the horizontal section 122 away from the vertical section 124. That is, the air outlet 120 has an inverted L-shaped structure.

[0070] like Figure 1-4As shown, in this embodiment, when the air outlet 120 is in its initial position, the horizontal section 122 is not higher than the top of the fixed part 110; and the distance between the fresh air outlet 121 and the central axis of the vertical section 124 is not greater than the distance between the central axis of the vertical section 124 and the front panel of the fixed part 110. Preferably, when the air outlet 120 is in its initial position, the horizontal section 122 is flush with the top of the fixed part 110, and the distance between the fresh air outlet 121 and the central axis of the vertical section 124 is equal to the distance between the central axis of the vertical section 124 and the front panel of the fixed part 110. The distance between the fresh air outlet 121 and the central axis of the vertical section 124 is greater than the distance between the central axis of the vertical section 124 and the side panel of the fixed part 110.

[0071] like Figure 9 As shown, preferably, the horizontal section 122 and the vertical section 124 of the air outlet 120 are connected by a rounded transition, that is, the air outlet 120 also includes a rounded section 123.

[0072] The above settings reduce the resistance of fresh air flowing from the vertical section 124 to the horizontal section 122, thereby reducing noise. At the same time, they also improve the appearance of the air outlet 120.

[0073] like Figure 3 , 6 As shown in Figures 9 and 1, preferably, the horizontal segment 122 is tapered, gradually decreasing in size along its extension direction. That is, the end of the horizontal segment 122 closer to the vertical segment 124 is the larger diameter end, and the end of the horizontal segment 122 farther from the vertical segment 124 is the smaller diameter end. This configuration increases the outlet velocity of the fresh air and also increases the travel distance of the fresh air after it exits the fresh air outlet 121, thereby further increasing the amount of fresh air participating in heat exchange. In some alternative embodiments of the present invention, the horizontal segment 122 may also be a straight cylinder with a uniform diameter along its extension direction.

[0074] like Figure 5 , 7 As shown, more preferably, the cross-section of the horizontal segment 122 is elliptical; along the extending direction of the horizontal segment 122, the cross-section of the horizontal segment 122 gradually decreases. In this embodiment, the elliptical cross-section of the horizontal segment 122 reduces the height of the horizontal segment 122 while increasing its width, thereby ensuring the air volume of the fresh air outlet while reducing the height; it also gives the horizontal segment 122 a streamlined appearance, enhancing the aesthetics of the outer ring. In some alternative embodiments of the present invention, the cross-section of the horizontal segment 122 is circular, square, rectangular, or triangular.

[0075] like Figure 7-11As shown, in some preferred embodiments of the present invention, the air outlet 120 is mounted on the fixed part 110 via a mounting base 130. The mounting base 130 is a cylindrical structure, and a guide rail 131 is provided on the outer periphery of the mounting base 130. The vertical section 124 of the air outlet 120 is fitted onto the mounting base 130 and can move along the guide rail 131 to raise and lower during rotation. In this embodiment, because the guide rail 131 is provided, the air outlet 120 can simultaneously change its angle and height while rotating along the guide rail 131; therefore, the above structure is simple and reliable, and can reduce costs.

[0076] Furthermore, the upper surface of the guide rail 131 is a bent and extended track surface, and the lower end face of the vertical section 124 of the air outlet 120 contacts the upper surface of the track surface, so that it can rise or fall along the track surface during rotation. Since the lower end face of the vertical section 124 of the air outlet 120 contacts the upper surface of the track surface, the guide rail 131 provides guidance and support for the air outlet 120 as it moves along the guide rail 131. This support increases the structural stability of the air outlet 120.

[0077] Furthermore, the lower end face of the vertical section 124 is adapted to the upper surface of the track surface so as to contact the track surface in the initial position and rise along the track surface when rotating from the initial position. This arrangement prevents reverse rotation of the air outlet 120, thereby avoiding errors.

[0078] like Figure 11 As shown, in this embodiment, the track surface includes a vertical surface 1311, a first horizontal surface 1312, an inclined surface 1313, and a second horizontal surface 1314 that are sequentially distributed along the outer periphery of the mounting base 130. The distance between the vertical surface 1311 and the inclined surface 1313 gradually increases from bottom to top. The first horizontal surface 1312 extends from the bottom of the vertical surface 1311 to the bottom of the inclined surface 1313, and the second horizontal surface 1314 extends from the top of the inclined surface 1313 to the top of the vertical surface 1311.

[0079] Correspondingly, the lower end face of the air outlet 120 is adapted to the track surface of the guide rail 131, and the lower end face of the air outlet 120 has a vertical section, a horizontal section, and an inclined section. Specifically, when the air outlet 120 is in the initial position, the horizontal section of the lower end face of the air outlet 120 contacts the first horizontal surface 1312, the vertical section contacts the vertical surface 1311, and the inclined section contacts the inclined surface 1313; when the air outlet 120 is facing the left or right side of the fixed part 110, the horizontal section of the lower end face of the air outlet 120 contacts the second horizontal surface 1314.

[0080] Therefore, the vertical section of the air outlet 120 has a blocking and limiting function, which can prevent the air outlet 120 from rotating in the reverse direction in the initial position; the first horizontal plane and the second horizontal plane have a supporting function for the vertical section 124, which can increase the structural stability of the air outlet 120.

[0081] In some alternative embodiments of the present invention, the vertical section 124 and the mounting base 130 are connected by threads. For example, the outer peripheral surface of the vertical section 124 is provided with external threads, and the inner wall of the mounting base 130 is provided with internal threads; or, the inner wall of the vertical section 124 is provided with internal threads, and the outer peripheral surface of the mounting base 130 is provided with external threads. The external or internal threads on the mounting base 130 are guide rails 131.

[0082] In some alternative embodiments of the present invention, the vertical section 124 may also be a telescopic rod that can extend and retract in the vertical direction, and the vertical rod is rotatably mounted on the fixed part 110.

[0083] In some optional embodiments of the present invention, the fresh air module 100 further includes a driving device for driving the air outlet 120 to move along the guide rail 131. By providing a driving device, the manual driving of the air outlet 120 can be eliminated, thereby improving the user experience.

[0084] Preferably, the drive device includes a drive gear 141 mounted on the fixed part 110 and a driven gear 142 sleeved on the vertical section 124 of the air outlet part 120. The driven gear 142 meshes with the drive gear 141, and the width of the driven gear 142 is greater than the width of the drive gear 141. In use, while the drive gear 141 drives the driven gear 142 to rotate, the driven gear 142 can move up and down relative to the drive gear 141 under the guidance of the guide rail 131.

[0085] like Figure 1-4 As shown, the fresh air module 100 can be installed at the left or right end of the heat exchange section 200; or, the fresh air module 100 can be installed at both the left and right ends of the heat exchange section 200.

[0086] In some alternative embodiments of the present invention, the upper surface of the fresh air section is not higher than the upper surface of the heat exchange section 200. Preferably, the upper surface of the fresh air section is flush with the upper surface of the heat exchange section 200, which makes the air conditioning device more aesthetically pleasing and neat.

[0087] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
