Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner indoor unit and an air conditioner. BACKGROUND

[0002] With the development of economy, air conditioners are used more and more widely. In order to simultaneously meet the purpose of air purification, a fresh air conditioner is also born.

[0003] At present, the fresh air conditioner in the industry is usually front air outlet, that is, the air outlet is on the same side of the main air duct of the air conditioner indoor unit. The main purpose of this is to mix the air blown out by the main air duct, so that the fresh air is blown farther, and at the same time, the user is more likely to perceive the fresh air function. However, this air outlet mode makes the fresh air conditioner have a large noise during use, and the temperature difference between the fresh air and the air blown out by the main air duct is often large, and the mixture of the two is not uniform, which will bring the user a cold and hot alternating feeling, and the comfort is poor. SUMMARY

[0004] The first object of the present application is to provide an air conditioner indoor unit to solve the technical problems of large noise, large temperature difference of fresh air outlet, and poor comfort of the existing fresh air conditioner during use.

[0005] The air conditioner indoor unit provided by the present application comprises an outer shell and a fresh air fan, the outer shell comprises a front panel and a rear panel, the front panel is provided with an air conditioner air outlet and a first fresh air outlet, the rear panel is provided with an air conditioner air inlet, a fresh air inlet and a second fresh air outlet, the fresh air fan is arranged in the inner part of the outer shell, the fresh air inlet is communicated with the air inlet of the fresh air fan, the fresh air fan is matched with the first fresh air outlet to be provided with a first air outlet duct, and the fresh air fan is also matched with the second fresh air outlet to be provided with a second air outlet duct.

[0006] When the fresh air function of the air conditioner indoor unit is turned on during use, the airflow will enter the air inlet of the fresh air fan through the fresh air inlet provided in the rear panel, and then flow to the first fresh air outlet through the first air outlet duct of the fresh air fan, and flow to the second fresh air outlet through the second air outlet duct of the fresh air fan, and finally be discharged to the indoor.

[0007] The air conditioner indoor unit is provided with the first air outlet duct and the second air outlet duct in the fresh air fan, so that the fresh air can be blown to the indoor from two different positions, that is, the first fresh air outlet provided in the front panel and the second fresh air outlet provided in the rear panel, which reduces the air outlet amount of each position alone, thereby effectively solving the technical problem of large noise when the air conditioner indoor unit operates in the fresh air function.

[0008] Further, since the amount of fresh air blown out by the front panel is reduced, that is, the amount of fresh air blown out by the fresh air outlet on the same side as the air outlet of the air conditioner is reduced, the interference of the fresh air on the air cooling / heating process of the air conditioner is reduced, the alternating feeling of cold and heat caused by the temperature difference between the fresh air and the air blown out by the air conditioner is weakened, the temperature difference of the fresh air blown out is reduced, and the comfort is improved. In addition, since the air conditioner indoor unit can blow fresh air to the indoor space through multiple positions, the uniformity of the distribution of fresh air in the indoor space is ensured, and the comfort experience of the user is further improved.

[0009] At least part of the air inlet of the air conditioner forms the second fresh air outlet, and the air inlet of the air conditioner is provided with a flow guide cover having a flow guide surface arranged at an angle with the horizontal plane, and the flow guide surface is configured to blow fresh air obliquely upward from the second air outlet.

[0010] Since a part of the fresh air is blown out by the air inlet of the air conditioner, when the air conditioner indoor unit is started in the cooling / heating mode, the main air duct of the air conditioner indoor unit is opened, and the part of the fresh air is sucked into the air inlet of the air conditioner, and after heat exchange with the heat exchanger, the part of the fresh air sucked in is blown out by the air outlet of the air conditioner. This form of sucking a part of fresh air into the main air duct and then blowing it out by the air outlet of the air conditioner can pre-cool / pre-heat the fresh air, so that the fresh air is blown to the room at the air outlet temperature set by the user, further avoiding the alternating feeling of cold and heat caused by the mixing of fresh air and air blown out by the main air duct, thereby further improving the comfort of the user. At the same time, the setting of the flow guide cover makes the fresh air blown out by the air inlet of the air conditioner have a large air supply area, so that the part of the fresh air can fully circulate in the room, effectively improving the air quality.

[0011] Further, the flow guide cover further comprises an air inlet grille, which is arranged inclinedly towards the inside of the shell in the direction from bottom to top. In this way, the air inlet surface of the air inlet of the air conditioner is an inclined surface, which can increase the unit air inlet amount at the air inlet of the air conditioner.

[0012] Further, the fresh air fan comprises a volute and a wind wheel, the volute comprises a first side wall, a second side wall and a top cover plate, the first side wall comprises a first air duct part and a first air outlet part arranged at an angle, the second side wall comprises a second air duct part and a second air outlet part arranged at an angle, and the top cover plate comprises a first air guide part and a second air guide part. The first air duct part and the second air duct part are connected to form a fresh air duct, the first air outlet part and the first air guide part are connected to form the first air outlet, and the second air outlet part and the second air guide part are connected to form the second air outlet.

[0013] When the air conditioner indoor unit is in use, after the fresh air function of the air conditioner indoor unit is turned on, the fan wheel of the fresh air fan rotates, driving the airflow to enter from the air inlet of the fresh air fan, and then flow to the first air outlet and the second air outlet through the fresh air duct. Then, the airflow is discharged to the indoor environment through the first fresh air outlet and the second fresh air outlet of the air conditioner indoor unit. Since the volute of the fresh air fan is formed by the butt joint of the first side wall, the second side wall and the top cover plate in the shape of "Y", on the one hand, the extension direction of the joint between the first air duct and the second air duct in the fresh air duct, the extension direction of the joint between the first air duct and the first air outlet in the first air outlet, and the extension direction of the joint between the second air duct and the second air outlet in the second air outlet are all along the flow direction of the fresh air in the current air duct. This arrangement reduces the pressure loss of the fresh air during flow in the air duct, not only ensures the smoothness of the fresh air flow, but also reduces the fluctuation and vortex of the fresh air during flow, thereby reducing the airflow noise. On the other hand, the type of the volute also simplifies the manufacturing process of the volute, which is not only convenient for processing and manufacturing, but also reduces the manufacturing cost of the volute.

[0014] Further, the air inlet of the fresh air fan is opened in the fresh air duct, and the fan wheel is arranged in the fresh air duct. The fan wheel is configured to make the airflow enter from the air inlet, flow to the first air outlet and the second air outlet through the fresh air duct; the air outlet of the first air outlet is communicated with the first fresh air outlet, and the air outlet of the second air outlet is communicated with the second fresh air outlet. By arranging the fan wheel in the fresh air duct, sufficient power can be provided for the flow of fresh air to the first air outlet and the second air outlet, so that the fresh air is smoothly blown out from the first fresh air outlet and the second fresh air outlet.

[0015] Further, the fresh air fan further comprises a damper, which is configured to control the amount of air flowing from the fresh air duct to the first air outlet and the second air outlet. In this way, when the user uses the fresh air fan, the user can flexibly control the amount of air blown out from the first air outlet and the second air outlet according to the use demand, and the use scene is rich, thereby further improving the user's use experience.

[0016] Further, the air valve comprises a guide vane rotatably arranged at the connection between the first air outlet channel and the second air outlet channel, the guide vane having a first position, a second position and a third position, wherein the first position is a position in which the first air outlet channel and the second air outlet channel are both in communication with the fresh air channel; the second position is a position in which the fresh air channel is disconnected from the first air outlet channel and the fresh air channel is in communication with the second air outlet channel; and the third position is a position in which the fresh air channel is in communication with the first air outlet channel and the fresh air channel is disconnected from the second air outlet channel. The air valve is arranged in this way, which not only can reliably regulate the air outlet volume of the first air outlet channel and the second air outlet channel, but also has a simple structure and low cost.

[0017] Further, the guide vane is fixedly connected with a rotating shaft, the rotating shaft is pivotally connected to the volute, and the air valve further comprises a guide vane motor, the guide vane motor is installed on the volute, and a motor shaft of the guide vane motor is drivingly connected with the rotating shaft. The air valve is arranged in this way, which realizes automatic swinging of the guide vane, has a high degree of automation, and is convenient to use.

[0018] Further, one side of the first air channel part facing the second air channel part is provided with a first vertical splicing part, one side of the second air channel part facing the first air channel part is provided with a second vertical splicing part, and the second vertical splicing part is spliced with the first vertical splicing part; and / or one side of the top cover plate facing the fresh air channel is provided with a first horizontal splicing part, and one side of the first air outlet part and the second air outlet part both facing the top cover plate is provided with a second horizontal splicing part, and the second horizontal splicing part is spliced with the first horizontal splicing part. In this way, the first air channel part and the second air channel part form a certain overlap at the abutting position, the top cover plate and the first side wall form a certain overlap at the abutting position, and the top cover plate and the second side wall form a certain overlap at the abutting position, which reduces the air leakage of fresh air at each abutting position and ensures the smoothness of air outlet.

[0019] Further, the first air outlet channel and the second air outlet channel are substantially parallel, and the air outlet of the first air outlet channel and the air outlet of the second air outlet channel are arranged opposite to each other. This air outlet form in two opposite directions can reduce noise, avoid the fresh air from converging at the two air outlets to affect the air outlet, and reduce the eddy current.

[0020] Further, the first fresh air outlet comprises a plurality of dispersed air outlets. In this way, the first fresh air outlet is arranged in the form of a plurality of dispersed air outlets, so that the fresh air blown out of the first fresh air outlet is softer and more comfortable, and the fresh air blown out of the first fresh air outlet does not directly blow on the user.

[0021] The second object of the present application is to provide an air conditioner to solve the technical problems of the prior art that the new air conditioner has a large noise during use, a large temperature difference of the new air outlet, and poor comfort.

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] like Figures 7 to 9 As shown, this embodiment provides an indoor air conditioning unit, including a housing 020 and a fresh air fan 010. Specifically, the housing 020 includes a front panel 021 and a rear panel 022. The front panel 021 has an air conditioning outlet 024 and a first fresh air outlet 025. The rear panel 022 has an air conditioning inlet 023, a fresh air inlet 026, and a second fresh air outlet. The fresh air fan 010 is disposed inside the housing 020. The fresh air inlet 026 is connected to the inlet of the fresh air fan 010. The fresh air fan 010 is matched with the first fresh air outlet 025 and has a first air outlet duct 150. The fresh air fan 010 is also matched with the second fresh air outlet and has a second air outlet duct 160.

[0041] When the air conditioner indoor unit is in use, when the fresh air function of the air conditioner indoor unit is turned on, the airflow will enter the air inlet of the fresh air fan 010 through the fresh air inlet 026 opened in the rear panel 022, and then flow to the first fresh air outlet 025 through the first air outlet duct 150 of the fresh air fan 010, and to the second fresh air outlet through the second air outlet duct 160 of the fresh air fan 010, and finally be discharged to the indoor.

[0042] The air conditioner indoor unit can make the fresh air blown to the indoor from two different positions, the first fresh air outlet 025 opened in the front panel 021 and the second fresh air outlet opened in the rear panel 022, by setting the first air outlet duct 150 and the second air outlet duct 160 in the fresh air fan 010, which reduces the air volume of each position alone, thereby effectively solving the technical problem of large noise when the air conditioner indoor unit operates in fresh air function.

[0043] Moreover, since the air volume blown by the front panel 021 is reduced, that is, the air volume of the fresh air outlet on the same side as the air outlet 024 of the air conditioner is reduced, the interference of the fresh air on the air conditioning cooling / heating air discharge process is reduced, the alternating feeling of cold and heat brought to the user due to the temperature difference between the fresh air and the air outlet of the air conditioner is weakened, the temperature difference of the fresh air outlet is reduced, and the comfort is improved. In addition, since the air conditioner indoor unit can blow fresh air to the indoor through multiple positions, the uniformity of the distribution of fresh air in the indoor space is ensured, and the comfort experience of the user is further improved.

[0044] Please continue to refer to Figure 7 and Figure 9 In this embodiment, the fresh air fan 010 is arranged at the bottom of the shell 020, the air inlet 023 and the air outlet 024 of the air conditioner are higher than the fresh air fan 010, the fresh air outlet 025 is located below the air outlet 024 of the air conditioner, and the fresh air pipe (not shown in the figure) is inserted in the fresh air outlet 025. Among them, the air outlet 024 of the air conditioner faces forward, and the air inlet 023 of the air conditioner faces backward.

[0045] By arranging the fresh air fan 010 at the bottom of the shell 020, the second air outlet duct 160 of the fresh air fan 010 is closer to the air inlet 023 of the air conditioner, so that when the cooling / heating mode of the air conditioner indoor unit is turned on, the fresh air blown by the second air outlet duct 160 can enter through the air inlet 023 in time, and after heat exchange with the main air duct 030, it is blown out through the air outlet 024 of the air conditioner.

[0046] Moreover, this form of blowing fresh air from the front and rear areas of the air conditioner indoor unit can also achieve large-area air supply of fresh air, so that the circulation of fresh air in the room is accelerated, and the room air quality is further improved.

[0047] Please continue to refer to Figure 7 and Figure 9, at least part of the air conditioner air inlet 023 forms a second fresh air outlet, the air conditioner air inlet 023 is provided with a flow guide cover 040, the flow guide cover 040 has a flow guide surface 041 arranged at an angle with the horizontal plane, and the flow guide surface 041 is configured to make the fresh air blow out obliquely upward from the second air outlet duct 160.

[0048] Since a part of the fresh air is blown out by the air conditioner air inlet 023, when the air conditioner indoor unit is started in the cooling / heating mode, the main air duct 030 of the air conditioner indoor unit is opened, and this part of the fresh air can be sucked into the air conditioner air inlet 023, and after heat exchange with the heat exchanger, this part of the sucked fresh air will be blown out by the air conditioner air outlet 024. This form of sucking a part of the fresh air into the main air duct 030 and then blowing it out by the air conditioner air outlet 024 can pre-cool / pre-heat the fresh air, so that the fresh air is blown to the room at the air outlet temperature set by the user, further avoiding the alternating feeling of cold and heat brought to the user due to the uneven mixing of fresh air and air blown out by the main air duct 030, thereby further improving the user's use comfort.

[0049] By arranging the flow guide cover 040 at the air conditioner air inlet 023 and arranging the flow guide surface 041 in the flow guide cover 040 for making the fresh air blow out obliquely upward from the second air outlet duct 160, on the one hand, the fresh air blown out by the air conditioner air inlet 023 has a larger air supply area, so that this part of the fresh air can fully circulate in the room, effectively improving the air quality, on the other hand, this part of the fresh air is also closer to the air conditioner air inlet 023, when the cooling / heating mode of the air conditioner indoor unit is started, this part of the fresh air can enter the inside of the shell 020 through the air conditioner air inlet 023 in time, and after heat exchange of the heat exchanger, it is sent out by the air conditioner air outlet 024, so that the fresh air blown out by the air conditioner air outlet 024 is more comfortable.

[0050] Please continue to refer to Figure 7 and Figure 9 In the embodiment, the flow guide cover 040 can also include an air inlet grille 042, specifically, the air inlet grille 042 is arranged inclinedly towards the inside of the shell 020 in the direction from bottom to top.

[0051] In this way, the air inlet surface of the air conditioner air inlet 023 is a slope, which not only can increase the unit air inlet amount at the air conditioner air inlet 023, but also can converge the fresh air blown out from the second air outlet duct 160, optimize the flow path of the fresh air from the second air outlet duct 160 to the inside of the shell 020, so that this part of the fresh air can flow to the inside of the shell 020 as much as possible, and then be blown out by the air conditioner air outlet 024.

[0052] As Figure 1 and Figure 2As shown, the fresh air fan 010 includes a volute 100 and an impeller 200, the volute 100 includes a first side panel 110, a second side panel 120 and a top cover plate 130, the first side panel 110 includes a first air duct part 111 and a first air outlet part 112 arranged at an angle, the second side panel 120 includes a second air duct part 121 and a second air outlet part 122 arranged at an angle, and the top cover plate 130 includes a first air guide part 131 and a second air guide part 132.

[0053] Please continue to refer to Figure 1 and Figure 2 , in combination with Figure 3 , specifically, the first air duct part 111 and the second air duct part 121 are connected to form a fresh air duct 140, the first air outlet part 112 and the first air guide part 131 are connected to form a first air outlet duct 150, and the second air outlet part 122 and the second air guide part 132 are connected to form a second air outlet duct 160.

[0054] When the air conditioner indoor unit is in use, after the fresh air function of the air conditioner indoor unit is turned on, the impeller 200 of the fresh air fan 010 rotates, driving the airflow to enter the fresh air fan 010 from the air inlet, and then flow to the first air outlet duct 150 and the second air outlet duct 160 through the fresh air duct 140, and then be discharged to the indoor through the first fresh air outlet 025 and the second fresh air outlet of the air conditioner indoor unit.

[0055] In addition, since the volute 100 of the fresh air fan 010 is formed by the "Y" shape connection of the first side panel 110, the second side panel 120 and the top cover plate 130, on the one hand, the extension direction of the joint formed by the first air duct part 111 and the second air duct part 121 in the fresh air duct 140, the extension direction of the joint formed by the first air guide part 131 and the first air outlet part 112 in the first air outlet duct 150, and the extension direction of the joint formed by the second air guide part 132 and the second air outlet part 122 in the second air outlet duct 160 are all along the flow direction of the fresh air in the current air duct, this arrangement reduces the pressure loss of the fresh air during the flow in the air duct, not only ensures the smoothness of the fresh air flow, but also reduces the fluctuation and vortex of the fresh air during the flow, thereby reducing the airflow noise, on the other hand, the section form of the volute 100 also simplifies the manufacturing process of the volute 100, not only facilitates processing and manufacturing, but also reduces the manufacturing cost of the volute 100.

[0056] Please continue to refer to Figure 2The air inlet of the fresh air fan 010 is arranged in the fresh air duct 140, and the air wheel 200 is arranged in the fresh air duct 140. The air wheel 200 is configured to make the airflow enter from the air inlet, flow through the fresh air duct 140 to the first air outlet 150 and the second air outlet 160. The air outlet of the first air outlet 150 is in communication with the first fresh air outlet 025 of the shell 020 of the air conditioner indoor unit, and the air outlet of the second air outlet 160 is in communication with the second fresh air outlet of the shell 020 of the air conditioner indoor unit. By arranging the air wheel 200 in the fresh air duct 140, sufficient power can be provided for the flow of fresh air to the first air outlet 150 and the second air outlet 160, so that the fresh air is smoothly blown out from the first fresh air outlet 025 and the second fresh air outlet.

[0057] Please continue to refer to Figure 2 In this embodiment, the fresh air fan 010 further includes a wind driving motor 300, specifically, the wind driving motor 300 is installed on the volute 100 for driving the air wheel 200 to rotate. The wind driving motor 300 is fixed to the first side wall 110 by a motor gland 700.

[0058] Please continue to refer to Figures 1 to 3 In this embodiment, the fresh air fan 010 is provided with a HEPA (High Efficiency Particulate Arrestance) net 600 at the air inlet, which is used to filter the airflow before it enters the volute 100, so that it becomes fresh air. Specifically, the volute 100 is provided with a HEPA net box 500 outside, the HEPA net box 500 is provided with a filter opening, and the HEPA net 600 is installed on the filter opening, so as to realize the installation of the HEPA net 600 on the volute 100. The HEPA net box 500 is installed on the second side wall 120.

[0059] Please continue to refer to Figure 2 In this embodiment, the first air duct part 111 is provided with a first vertical splicing part 113 facing the second air duct part 121, and the second air duct part 121 is provided with a second vertical splicing part 123 facing the first air duct part 111, wherein the second vertical splicing part 123 is spliced with the first vertical splicing part 113.

[0060] This form of splicing the first vertical splicing part 113 with the second vertical splicing part 123 to realize the butt joint of the first air duct part 111 and the second air duct part 121 makes the first air duct part 111 and the second air duct part 121 form a certain overlap at the butt joint, which weakens or even avoids the air leakage of the fresh air duct 140 at the butt joint of the first air duct part 111 and the second air duct part 121, reduces the air pressure loss inside the fresh air duct 140, not only ensures the smoothness of the air outlet, but also reduces the turbulence inside the fresh air duct 140.

[0061] Please continue to refer to Figure 2 Similarly, the side of the top cover plate 130 facing the fresh air duct 140 is provided with a first transverse splicing part 133, and the side of the first air outlet part 112 and the second air outlet part 122 facing the top cover plate 130 is provided with a second transverse splicing part 170, and the second transverse splicing part 170 is spliced with the first transverse splicing part 133.

[0062] This splicing of the first transverse splicing part 133 and the second transverse splicing part 170 realizes the butt joint of the first air outlet part 112 and the first air guide part 131 and the butt joint of the second air outlet part 122 and the second air guide part 132, so that the top cover plate 130 and the first side wall 110 are overlapped at the butt joint, and the top cover plate 130 and the second side wall 120 are overlapped at the butt joint, which weakens or even avoids the air leakage of the first air duct 150 at the butt joint of the top cover plate 130 and the first side wall 110 and the air leakage of the second air duct 160 at the butt joint of the top cover plate 130 and the second side wall 120, reduces the air pressure loss inside the first air duct 150 and the second air duct 160, so that the fresh air can be smoothly blown out from the first air duct 150 and the second air duct 160.

[0063] Please continue to refer to Figures 1 to 3 In this embodiment, the first air duct 150 and the second air duct 160 are substantially parallel, and the air outlet of the first air duct 150 and the air outlet of the second air duct 160 are arranged in opposite directions.

[0064] This air outlet form in two opposite directions can reduce noise, avoid the intersection of fresh air at the two air outlets to affect air outlet, and reduce vortex.

[0065] It should be noted that in this embodiment, "the first air duct 150 and the second air duct 160 are substantially parallel" includes the case that the extension direction of the first air duct 150 is collinear with the extension direction of the second air duct 160, and the case that the extension direction of the first air duct 150 is at a certain angle (not greater than 10°) with the extension direction of the second air duct 160.
