Description

Technical Field

[0001] The invention belongs to the technical field of air conditioners, and in particular relates to air conditioners. Background Art

[0002] Air conditioner is an air conditioner, which is a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. With the development of the air conditioning industry and the improvement of people's living standards, people have put forward higher requirements for ambient air, and fresh air air conditioners have emerged. Fresh air air conditioners are a healthy and comfortable air conditioner with fresh air function. They use fresh air fans to achieve circulation and ventilation between indoor and outdoor air, and also have the function of purifying the air.

[0003] At present, the fresh air system of fresh air air conditioners is mainly divided into one-way flow fresh air system and two-way flow fresh air system according to wind direction. As the name implies, the one-way fresh air system has only one wind direction. The one-way fresh air systems currently on the market include positive pressure type (and negative pressure type. The positive pressure type actively introduces fresh air into the room, the indoor air pressure increases and forms a pressure difference with the outdoor air. The indoor turbid air is forced out of the room from the door gap, window gap, etc. under the action of the pressure difference. The negative pressure type actively discharges the turbid air in the room, the indoor air pressure decreases and forms a negative pressure environment, so that the outdoor fresh air enters the room under the action of the pressure difference. Regardless of the positive pressure one-way fresh air system or the negative pressure one-way fresh air system, both rely on the air pressure difference between indoor and outdoor for intake and exhaust. Once the indoor and outdoor air pressures are the same or the pressure difference is small, the circulation speed of indoor turbid air and outdoor fresh air will decrease, resulting in an increase in indoor carbon dioxide concentration, which is harmful to human health. The two-way flow fresh air system has both air supply and exhaust functions. The air intake and exhaust functions of the fresh air system are both realized by the operation of the fresh air fan. Since the installation position of the fresh air fan in the fresh air system is fixed , and in the same air duct, the fresh air fan cannot realize the air intake and exhaust functions at the same time. Therefore, in the prior art, the fresh air system is provided with an air intake duct and an exhaust duct at the same time, and the air intake duct is connected to the air inlet of the fresh air fan to introduce outdoor fresh air; the exhaust duct is connected to the air outlet of the fresh air fan to exhaust indoor turbid air; although the two-way flow fresh air system has higher ventilation efficiency than the one-way flow fresh air system, the fresh air system is complicated because the air intake duct and the exhaust duct are simultaneously provided in the fresh air system; and, because the air intake of the air intake duct and the exhaust duct need to be set outdoors, in order to introduce outdoor fresh air and exhaust indoor turbid air, the air intake duct and the exhaust duct are respectively connected with air ducts, and the air ducts extend through the wall to the outdoors, which results in the need to connect two air ducts to the fresh air system, which not only increases the difficulty and cost of installation, but also puts forward higher requirements for the installation space. Therefore, the air conditioner in the prior art cannot well meet people's demand for fresh air. Summary of the invention

[0004] In view of the deficiencies existing in the related art, the present invention provides an air conditioner to solve the problem in the prior art that the air conditioner needs to set up both an air inlet duct and an exhaust duct for two-way ventilation, which makes the overall structure of the air conditioner complicated and inconvenient to install.

When the second switching component 9 is in the opening state, the third air duct 12 is connected to the first air duct 51 and the second switching component 9 separates the fresh air outlet 511 of the first air duct 51 and the fresh air shell outlet 23; when the second switching component 9 is in the closing state, the third air duct 12 is separated from the first air duct 51. A third switching component 7 is provided at the connection point between the third air duct 12 and the second air duct 11. The third switching component 7 has at least two states, open and closed. When the third switching component 7 is in the open state, the third air duct 12 is connected to the second air duct 11; when the third switching component 7 is in the closed state, the third air duct 12 is separated from the second air duct 11.

[0057] When it is necessary to introduce outdoor fresh air, the first switching component 4 closes the fresh air shell air outlet 23, the second switching component 9 is closed, and the third switching component 7 is closed, and the outdoor fresh air is introduced into the first air duct 51 from the fresh air outlet 511 through the operation of the fresh air fan 8, and flows to the room from the fresh air outlet 111 through the second air duct 11; when it is necessary to discharge indoor foul air, the first switching component 4 opens the fresh air shell air outlet 23, the second switching component 9 is opened, and the third switching component 7 is opened, and the indoor foul air is introduced into the first air duct 51 from the fresh air shell air outlet 23 through the operation of the fresh air fan 8, and flows through the second air duct 11 and the third air duct 12 in sequence, and then flows to the outdoors from the fresh air outlet 511.

[0058] The above-mentioned air conditioner is provided with a first air duct 51, a second air duct 11 and a third air duct 12, and uses a second switching component 9 to control the connection or isolation of the first air duct 51 and the third air duct 12, and uses a third switching component 7 to control the connection or isolation of the second air duct 11 and the third air duct 12, so that outdoor fresh air is introduced into the room from the first air duct 51 and the second air duct 11 through the operation of the fresh air fan 8, and the indoor turbid air is discharged to the outside from the first air duct 51, the second air duct 11 and the third air duct 12, so that the above-mentioned air conditioner has the function of introducing outdoor fresh air and discharging indoor turbid air; outdoor fresh air is introduced or indoor turbid air is discharged by providing a fresh air outlet 511, and the fresh air outlet 511 is provided in the first air duct 51, so that the indoor turbid air and outdoor fresh air are discharged or introduced through the same air duct, thereby simplifying the overall structure of the above-mentioned air conditioner and facilitating installation.

[0059] It should be noted that, when the second switching component 9 is in the open state, the third air duct 12 is connected to the fresh air outlet 511 and the first air duct 51 is separated from the fresh air outlet 511; when the second switching component 9 is in the closed state, the third air duct 12 is separated from the fresh air outlet 511 and the first air duct 51 is connected to the fresh air outlet 511.

[0060] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the fresh air shell is located on one side of the volute and the two are connected into a whole, the volute includes a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are arranged opposite to each other and jointly form a second air duct 11 and a third air duct 12, the second air duct 11 and the third air duct 12 are connected to each other; the second shell 2 is provided with a grille opening 21, and the first air duct 511 is connected to the second air duct 11 through the grille opening 21; the fresh air opening 511 is located at one end of the first air duct 51 away from the grille opening 21; the fresh air outlet 111 is located at one end of the second air duct 11 away from the grille opening 21; the end of the third air duct 12 away from the second air duct 11 is connected to the first air duct 51; the fresh air shell 5 is located on the side of the second shell 2 away from the first shell 1, the fresh air shell 5 and the second shell 2 are arranged opposite to each other and jointly define the first air duct 51.

[0061] like Figure 5 and Figure 6 As shown, the air inlet of the fresh air fan 8 is arranged toward the grille opening 21, and the air outlet of the fresh air fan 8 is arranged toward the fresh air outlet 111, so that the air in the first air duct 51 is introduced into the second air duct 11 through the grille opening 21 through the operation of the fresh air fan 8, or the air in the second air duct 11 is introduced into the first air duct 51 through the third air duct 12.

[0062] Since there may be dust or other solid particles in the outdoor fresh air, it needs to be purified when it is introduced into the room to prevent it from affecting the indoor environment and reducing the cleanliness of the indoor turbid air. Figure 1-Figure 6 As shown, an air purification module is provided in the first air duct 51 to purify the air entering the second air duct 11 from the first air duct 51; the air purification module is installed in the purification frame 3 to facilitate setting the air purification mode in the first air duct 51; since the air purification module needs to be cleaned, replaced or overhauled regularly, in order to facilitate the installation and disassembly of the air purification module, the purification frame 3 is installed in the first air duct 51 in a detachable manner; an installation port 22 is opened on the top of the fresh air shell, and the purification frame 3 is inserted into the installation port 22 to install the purification frame 3 in the first air duct 51; when disassembling the purification frame 3, the purification frame 3 can be pulled out from the installation port 22; by installing the purification frame 3 in the first air duct 51 in a plug-in manner, the installation and disassembly of the purification frame 3 is facilitated; it should be noted that the working principle of the air purification module to purify air belongs to the common knowledge technology in the field and will not be repeated here.

[0063] In practical applications, sometimes it is necessary to purify the indoor stale air, but there is no need to introduce fresh air from the outside. In order to solve this technical problem, Figure 7 As shown, the purification frame 3 divides the first air duct 51 into a first cavity 512 and a second cavity 513. The first cavity 512 and the second cavity 513 are arranged in parallel and connected to each other. The first cavity 512 is connected to the outside and the fresh air outlet 511 is opened in the first cavity 512. The second cavity 513 is connected to the second air duct 11. When the air enters the second cavity 513 from the first cavity 512, it will pass through the air purification module. Therefore, if the air passes through the first cavity 512 and the second cavity 513 in sequence before entering the second air duct 11, the air entering the second air duct 11 is clean air purified by the air purification module. If the air enters the second air duct 11 directly from the second cavity 513, the air entering the second air duct 11 has not been purified by the air purification module. Figure 8As shown, the purification frame 3 divides the fresh air shell air outlet 23 into a first air outlet 231 and a second air outlet 232. The first air outlet 231 is opened in the first cavity 512, and the second air outlet 232 is opened in the second cavity 513. The indoor turbid air is introduced from the first air outlet 231 into the first cavity 512 through the operation of the fresh air fan 8, and enters the second cavity 513 after being purified by the air purification module, and then flows into the room through the fresh air outlet 111 through the second air duct 11, so that the indoor turbid air can be purified. In the process of purifying the indoor turbid air, opening the second switching component 9 can prevent the outdoor fresh air from entering the first air duct from the fresh air outlet 511. In 11, if the second switching component 9 is closed, the operation of the fresh air fan 8 introduces the indoor turbid air from the first air outlet 231 into the first chamber 512, and also introduces the outdoor fresh air from the fresh air outlet 511 into the first chamber 512. At this time, the air in the first chamber 512 is a mixture of outdoor fresh air and indoor turbid air. The mixed air enters the second chamber 513 after being purified by the air purification module, and then flows into the room from the fresh air outlet 111 through the second air duct 11; therefore, when the above-mentioned air conditioner purifies the indoor turbid air, it can either only purify the indoor turbid air, or purify the introduced outdoor fresh air when purifying the indoor turbid air.

[0064] Since the indoor foul air does not need to be purified when it is discharged, the indoor foul air is introduced into the second cavity 513 from the second air outlet 232 through the operation of the fresh air fan 8, and then flows to the outside from the fresh air outlet 511 through the second air duct 11 and the third air duct 12; when introducing outdoor fresh air, in order to prevent the fresh air fan 8 from introducing the indoor foul air from the first air outlet 231 and the second air outlet 232 into the first air duct 51 when operating, the first air outlet 231 and the second air outlet 232 need to be closed; in order to meet the needs of the working states of the first air outlet 231 and the second air outlet 232, the first switching component 4 can not only close the first air outlet 231 and the second air outlet 232 at the same time, but also open the first air outlet 231 and close the second air outlet 232, or close the first air outlet 231 and open the second air outlet 232.

[0065] like Fig.10 and Fig.11As shown, the first switching assembly 4 includes a mounting frame 45, a first motor 41 and a first baffle 43. The mounting frame 45 is mounted on the fresh air shell. The mounting frame 45 is provided with a through opening connected to the fresh air shell air outlet 23, and a slideway 451 extending in a direction perpendicular to the opening of the fresh air shell air outlet 23 is provided inside the mounting frame 45. The first baffle 43 is installed in the slideway 451 and slides along the slideway 451 to open or close the first air outlet 231 and the second air outlet 232; the mounting frame 45 is connected to the mounting shell 46, and a mounting cavity is provided in the mounting shell 46, which is connected to the slideway 451.

The air in the first cavity 512 is purified by the purification module and then enters the second air duct 11 through the second cavity 513; the third motor 72 drives the third baffle 71 to rotate to a closed state to separate the second air duct 11 from the third air duct 12, and the fresh air in the second air duct 11 flows from the fresh air outlet 111 to the room through the operation of the fresh air fan 8.

The indoor foul air is introduced into the second cavity 513 through the operation of the fresh air fan 8 from the second air outlet 232, and flows to the outside from the fresh air outlet 511 through the second air duct 11 and the third air duct 12. Specifically, the second motor 92 drives the second baffle 91 to rotate to an open state, the third air duct 12 is connected to the first air duct 51 and isolates the fresh air outlet 511 and the grille opening 21 of the first air duct 51 to prevent outdoor fresh air from entering the room from the fresh air outlet 511; the first motor 41 drives the first baffle 43 to move to the second position, opens the second air outlet 232, closes the first air outlet 231, and introduces indoor foul air from the second air outlet 232 into the second cavity 513 and into the second air duct 11 through the operation of the fresh air fan 8; the third motor 72 drives the third baffle 71 to rotate to an open state, so that the second air duct 11 is connected to the third air duct 12, and the air in the second air duct 11 is introduced into the second air duct 11 and the third air duct 12 in turn through the operation of the fresh air fan 8, and finally flows to the outdoors from the fresh air outlet 511.

Since the first air duct 51 is separated from the third air duct 12, the air in the first cavity 512 is purified by the purification module and then enters the second air duct 11 through the second cavity 513; the third motor 72 drives the third baffle 71 to rotate to a closed state, the second air duct 11 is separated from the third air duct 12, and the fresh air in the second air duct 11 flows from the fresh air outlet 111 to the room through the operation of the fresh air fan 8.

[0077] In the mixed air mode, the first switching component 4 is in the first position, the second switching component 9 is closed, and the third switching component 7 is closed. The indoor foul air is introduced into the first cavity 512 from the first air outlet 231 through the operation of the fresh air fan 8, and the outdoor fresh air is introduced into the first cavity 512 from the fresh air outlet 511, so that the indoor foul air and the outdoor fresh air are mixed in the first cavity 512 to form mixed air, which enters the second cavity 513 after purification by the air purification module, and flows into the room from the fresh air outlet 111 through the second air duct 11. Specifically: the first motor 41 drives the first baffle 43 to move to the first position, opens the first air outlet 231, and closes the second air outlet 232; the outdoor fresh air is introduced into the first cavity 512 of the first air duct 51 from the fresh air outlet 511 through the operation of the fresh air fan 8; the second motor 92 drives the second baffle 91 to rotate to a closed state, so that the first air duct 51 is separated from the third air duct 12, and the outdoor fresh air is introduced into the first cavity 512 of the first air duct 51 from the fresh air outlet 511 through the operation of the fresh air fan 8, so that the indoor stale air and the outdoor fresh air are mixed in the first cavity 512 to form a mixed wind; the third motor 72 drives the third baffle 71 to rotate to a closed state, the second air duct 11 is separated from the third air duct 12, and the fresh air in the second air duct 11 flows from the fresh air outlet 111 to the room through the operation of the fresh air fan 8.

[0078] The above-mentioned air conditioner has four working modes: fresh air mode, exhaust mode, self-purification mode and mixed air mode, which can meet users' various needs for indoor foul air. It can not only introduce outdoor fresh air and discharge indoor foul air, but also purify indoor foul air. At the same time, it can also introduce outdoor fresh air in the process of purifying indoor foul air.

[0079] Based on the above air conditioner, the present invention further provides a control method for the air conditioner, which controls the fresh air mode, exhaust mode, self-purification mode and mixed air mode of the air conditioner to make the above air conditioner operate in a certain mode; wherein the fresh air fan 8, the first motor 41, the second motor 92 and the third motor 72 are electrically connected to the controller respectively, so that the controller can control the operation of the fresh air fan 8 and the movement of the first baffle 43, the second baffle 91 and the third baffle 71; the control method of the air conditioner specifically includes the following steps:

[0080] When outdoor fresh air is introduced, Figure 4 , Figure 5 , Fig.12 and Fig.17 As shown, the controller controls the operation of the fresh air fan 8 and controls the first motor 41 to drive the first baffle 43 to slide in the slide 451 to the third position, so as to simultaneously close the first air outlet 231 and the second air outlet 232; controls the second motor 92 to drive the second baffle 91 to rotate to a closed state, so that the first air duct 51 is separated from the third air duct 12; at the same time, the third motor 72 drives the third baffle 71 to rotate to a closed state, so that the second air duct 11 is separated from the third air duct 12, and through the operation of the fresh air fan 8, the outdoor fresh air is introduced into the first cavity 512 from the fresh air outlet 511, and enters the second cavity 513 after purification by the air purification module, and then flows into the room from the fresh air outlet 111 through the second air duct 11, and the above-mentioned air conditioner enters the fresh air mode.

[0081] When exhausting indoor turbid air, Figure 3 , Figure 6 , Fig.13 and Fig.15 As shown, the controller controls the operation of the fresh air fan 8 and controls the first motor 41 to drive the first baffle 43 to slide in the slide 451 to the second position, thereby opening the second air outlet 232 and closing the first air outlet 231; controls the second motor 92 to drive the second baffle 91 to rotate to an open state, so that the third air duct 12 is connected to the first air duct 51 and the fresh air outlet 511 and the grille opening 21 of the first air duct 51 are isolated, so as to prevent outdoor fresh air from entering the room from the fresh air outlet 511; the third motor 72 drives the third baffle 71 to rotate to a closed state, so that the second air duct 11 is isolated from the third air duct 12; through the operation of the fresh air fan 8, the indoor foul air is introduced into the second cavity 513 from the second air outlet 232, and flows from the fresh air outlet 511 to the outdoors through the second air duct 11 and the third air duct 12, and the above-mentioned air conditioner enters the exhaust mode.

[0082] When purifying indoor stale air and not introducing outdoor fresh air, Figure 3 , Figure 5 , Fig.12 and Fig.16 As shown, the controller controls the operation of the fresh air fan 8 and controls the first motor 41 to drive the first baffle 43 to slide in the slide 451 to the first position, so as to open the first air outlet 231 and close the second air outlet 232; controls the second motor 92 to drive the second baffle 91 to rotate to an open state, so that the fresh air outlet 511 of the first air duct 51 is separated from the fresh air shell air outlet 23 and the first air duct 51 is connected to the third air duct 12; at the same time, the third motor 72 drives the third baffle 71 to rotate to a closed state, so that the second air duct 11 is separated from the third air duct 12, and the indoor foul air is introduced into the first cavity 512 from the first air outlet 231 through the operation of the fresh air fan 8, and after purification by the air purification module, it passes through the second cavity 513 and the second air duct 11 and flows from the fresh air outlet 111 to the indoor room, and the above-mentioned air conditioner enters the self-purification mode.

[0083] When purifying the indoor stale air and introducing outdoor fresh air, Figure 4 , Figure 5 , Fig.12 and Fig.17 As shown, the controller controls the operation of the fresh air fan 8 and controls the first motor 41 to drive the first baffle 43 to slide in the slide 451 to the first position, so as to open the first air outlet 231 and close the second air outlet 232; controls the second motor 92 to drive the second baffle 91 to rotate to a closed state, so that the first air duct 51 is separated from the third air duct 12; at the same time, the third motor 72 drives the third baffle 71 to rotate to a closed state, so that the second air duct 11 is separated from the third air duct 12; through the operation of the fresh air fan 8, the indoor turbid air is introduced into the first cavity 512 from the first air outlet 231, and the outdoor fresh air is introduced into the first cavity 512 from the fresh air outlet 511, so that the indoor turbid air and the outdoor fresh air are mixed in the first cavity 512 to form a mixed wind, which enters the second cavity 513 after purification by the air purification module, and flows into the room from the fresh air outlet 111 through the second air duct 11, and the above-mentioned air conditioner enters the mixed air mode.

[0084] It should be noted that, in some embodiments, the third baffle 71 can rotate between an open state and a closed state. By adjusting the rotation angle of the third baffle 71 between the open state and the closed state, the air outlet volume of the fresh air outlet 111 can be adjusted; when the first baffle 43 slides along the slide 451, it can stop moving at any position of the slide 451, so that the first baffle 43 can adjust the air outlet size of the first air outlet 231 and the second air outlet 232, and then adjust the air intake volume of the first air outlet 231 and the second air outlet 232.

[0085] The air volume of the fresh air mode is adjusted by adjusting the rotation angle of the third baffle 71. When the third baffle 71 is rotated to between the open state and the closed state, although the second air duct 11 and the third air duct 12 are both in a semi-open state, the air originally flowing into the room from the fresh air outlet 111 of the second air duct 11 may enter the third air duct 12. However, since the second baffle 91 is in a closed state in the fresh air mode, the first air duct 51 is separated from the third air duct 12. Therefore, the air entering the third air duct 12 cannot circulate. Therefore, adjusting the air volume of the second air duct 11 by adjusting the rotation angle of the third baffle 71 will not affect the operation of the above-mentioned air conditioner in the fresh air mode.

[0086] The air volume in the self-purification mode is adjusted by adjusting the size of the first air outlet 231, but cannot be adjusted by adjusting the rotation angle of the third baffle 71. Since in the self-purification mode, the second baffle 91 is in a closed state, the first air duct 51 is connected to the third air duct 12 at this time. If the third baffle 71 is rotated between the open state and the closed state, the second air duct 11 and the third air duct 12 will be in a semi-open state. The air originally flowing into the room from the fresh air outlet 111 of the second air duct 11 may enter the third air duct 12. At this time, the third air duct 12 is connected to the first air duct 51, and the air in the third air duct 12 will flow into the room from the fresh air outlet 511. Therefore, adjusting the air volume of the second air duct 11 by adjusting the rotation angle of the third baffle 71 will affect the operation of the above-mentioned air conditioner in the self-purification mode. Therefore, the air volume of the above-mentioned air conditioner in the self-purification mode is adjusted by adjusting the size of the air outlet of the first air outlet 231.

[0087] The air volume of the exhaust mode is adjusted by adjusting the size of the second air outlet 232; in the mixed air mode, the mixing ratio of indoor stale air and outdoor fresh air in the first chamber 512 and the air volume of the mixed air mode can be adjusted by adjusting the size of the first air outlet 231.

[0088] The air conditioner can switch between fresh air mode, exhaust mode, self-purification mode and mixed air mode by controlling the first motor 41, the second motor 92 and the third motor 72 through the controller, so as to meet the user's various needs for indoor foul air, and the switching efficiency is high; adjusting the rotation angle of the third baffle 71 can adjust the air volume of the fresh air mode, adjusting the size of the first air outlet 231 can adjust the air volume of the self-purification mode and the mixing ratio of indoor foul air and outdoor fresh air in the first chamber 512 in the mixed air mode and the air volume of the mixed air mode, and adjusting the size of the second air outlet 232 can adjust the air volume of the exhaust mode. By making the air volume in each working mode adjustable, the air conditioner can better meet the needs of users.
