Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 5 show a preferred embodiment of the present invention.
The indoor unit of the air conditioner can be a cabinet air conditioner, an on-hook air conditioner or a ceiling air conditioner 100, and includes a first air guiding opening 111 and a second air guiding opening 121, where the first air guiding opening 111 and the second air guiding opening 121 are both used for guiding air flow into or out of the indoor unit of the air conditioner. When the first air guide opening 111 guides the environmental air flow (air flow outside the air-conditioning indoor unit) into the air-conditioning indoor unit, the environmental air guided into the air-conditioning indoor unit is guided out of the air-conditioning indoor unit through the second air guide opening 121 after heat exchange is carried out by the heat exchange component 150 of the air-conditioning indoor unit; when the second air guiding opening 121 guides the ambient air flow into the air-conditioning indoor unit, the ambient air guided into the air-conditioning indoor unit is guided out of the air-conditioning indoor unit through the first air guiding opening 111 after heat exchange of the heat exchange component 150 of the air-conditioning indoor unit. In other words, when the first air guiding opening 111 is an air inlet of an air conditioner indoor unit, the second air guiding opening 121 is an air outlet of the air conditioner indoor unit; when the first air guiding opening 111 is an air outlet of an indoor unit of an air conditioner, the second air guiding opening 121 is an air inlet of the indoor unit of the air conditioner. In particular, the vertical height of the second air guiding opening 121 is lower than the vertical height of the first air guiding opening 111.
The air-conditioning indoor unit is also provided with an air supply device, the air supply device has a first working state and a second working state, and the air supply device is configured to lead out the heat exchange air flow of the air-conditioning indoor unit from the first air guide opening 111 in the first working state and lead out the heat exchange air flow of the air-conditioning indoor unit from the second air guide opening 121 in the second working state. That is, whether the first air guiding opening 111 and the second air guiding opening 121 are air inlets or air outlets is determined by the working state of the air supply device. When the air supply device is in a first working state, the first air guide opening 111 is an air outlet, and the second air guide opening 121 is an air inlet; when the air supply device is in the second working state, the first air guiding opening 111 is an air inlet, and the second air guiding opening 121 is an air outlet.
Specifically, in order to make the air conditioner have high heat exchange efficiency, the air supply device may be in a first operating state when the air conditioner is in the cooling mode, and the air supply device may be in a second operating state when the air conditioner is in the heating mode. Like this, derive cold wind by the higher first wind-guiding mouth 111 of vertical height when air conditioner is cold, because the hot-air in the environment easily suspends in the higher position of vertical height, the event lets cold wind blow to the eminence can make cold wind carry out the heat exchange with the hot-air in the environment more easily to let the heat exchange of cold wind more abundant, the refrigeration effect is better. When the air conditioner is heating, the second air guide opening 121 with lower vertical height guides hot air out, and cold air in the environment easily sinks to the lower part of the vertical height, so that the hot air is blown to the lower part to enable the hot air to exchange heat with the cold air in the environment more easily, the hot air exchange is more sufficient, and the heating effect is better.
In the embodiment, in order to make the experience effect of the user better, when the air conditioner is in a cooling mode and a heating mode, the air supply device is in a first working state or in a second working state, when the air conditioner is in the first working state, cold air and hot air are both sprayed out from the part with the lower vertical height, and the hot air and the cold air can be blown to the user more quickly, so that the user can quickly heat or cool the user; when the first working state is the first working state, the user can be prevented from directly blowing, and the user is prevented from being overheated or catching a cold. The specific working state of the air supply device is determined by the actual requirements of users. In one embodiment, the working state of the air supply device may be set corresponding to the working mode of the indoor unit of the air conditioner. The working mode of the air conditioner is selected to be the energy-saving mode by a user, the air supply device defaults to be the first working state when the air conditioner is used for refrigerating, and the air supply device defaults to be the second working state when the air conditioner is used for heating, so that the heat exchange efficiency of heat exchange airflow blown out by the air conditioner is higher, and more energy is saved. When the user selects the working mode of the air conditioner as a comfortable mode, the air supply device is defaulted to be in a first working state when the air conditioner refrigerates and heats, and the direct blowing of heat exchange airflow to the user is avoided.
In one embodiment, in order to prevent the air flows ejected from the first air guiding opening 111 and the second air guiding opening 121 of the indoor unit of the air conditioner from affecting each other, the heat exchange air flow in the indoor unit of the air conditioner may be ejected transversely from the first air guiding opening 111. Specifically, the heat exchange airflow in the air conditioning indoor unit can be ejected horizontally or obliquely upward or obliquely downward at a certain angle, so that when the first air guide opening 111 is an air outlet, the heat exchange airflow ejected from the first air guide opening 111 is not easy to flow back into the second air guide opening 121 to form a short circuit. In another embodiment, when the second air guiding opening 121 is an air outlet, the heat exchange air flow of the indoor unit of the air conditioner can be vertically ejected downwards out of the second air guiding opening 121, so that the air flow ejected out of the second air guiding opening 121 is not easy to flow back to the first air guiding opening 111.
In order to facilitate the lateral air flow, the indoor unit may be a ceiling unit 100. The ceiling-suspended ceiling fan 100 may be disposed at an indoor ceiling, and a wide space is formed around the ceiling, so that the airflow jetted from the first air guide opening 111 is not easily blown to an indoor wall, and thus the airflow jetted from the first air guide opening 111 can have a longer lift.
Specifically, furring machine 100 includes diapire 120 and along the lateral wall 110 of the outward flange vertical extension of diapire 120 upwards, and the upper end edge of lateral wall 110 is connected with the roof opposite with diapire 120, and the roof can set up with the lower surface parallel and level of indoor furred ceiling for the roof imbeds among the furred ceiling. The first air guiding opening 111 is disposed around the side wall 110, so that the air flow ejected from the first air guiding opening 111 can be diffused toward the periphery of the ceiling fan 100. Specifically, the first air guiding opening 111 may be one opening on the side wall 110, or may be a plurality of openings on the side wall 110, and when the side wall 110 has a plurality of openings, the plurality of openings of the first air guiding opening 111 may be arranged at equal intervals. The second air guiding opening 121 is disposed on the bottom wall 120, and specifically, may be disposed at a central position of the bottom wall 120, so that the second air guiding opening 121 may vertically and downwardly inject the air flow.
When the indoor unit of the air conditioner is the ceiling unit 100, in one embodiment, the illuminating lamp 123 can be further arranged on the bottom wall 120, and the illuminating lamp 123 is used for illuminating the outside of the ceiling unit 100, so that the ceiling unit 100 of the air conditioner can be used as a ceiling lamp, the problem that the ceiling unit 100 of the indoor air conditioner and the illuminating lamp 123 are prone to position interference is solved, the space of a ceiling is saved, and the cost is saved. Meanwhile, the side wall 110 of the ceiling fan 100 is provided with the second air guide opening 121, so that the opening area of the bottom wall 120 of the ceiling fan 100 can be reduced, the bottom wall 120 can be provided with the larger space arrangement illuminating lamps 123, and the whole volume of the ceiling fan 100 can be reduced.
In order to make the first air guiding opening 111 spray air flow outwards at any angle in the horizontal plane, the bottom wall 120 and the top wall may be circular, the side wall 110 is circular, and the plurality of openings arranged on the side wall 110 are arranged in a circular array. In particular, when furred ceiling machine 100 is the cylinder, can connect three spinal branch posts to fix a position on the roof, for the structure that is the furred ceiling machine 100 of cuboid and utilizes four spinal branch posts to fix a position, the mode of three spinal branch posts location can prevent to cross the location to furred ceiling machine 100 when material saving.
The first air guiding structure 112 is disposed at the first air guiding opening 111, and the first air guiding structure 112 is used for guiding the air flow ejected from the first air guiding opening 111 and changing the size of the opening of the first air guiding opening 111. To facilitate maintenance of the ceiling suspended engine 100, in one embodiment, a first end of the first wind guiding structure 112 of the ceiling suspended engine 100 is hinged to the side wall 110 of the ceiling suspended engine 100, and a second end opposite to the first end is clamped to the side wall 110. As shown in fig. 3, when needing to be maintained, the joint end of the first wind guiding structure 112 is opened, and the first wind guiding structure 112 is rotated around the hinge end thereof, so that the first wind guiding structure 112 can be opened, and the inside of the ceiling fan 100 can be cleaned and maintained and checked conveniently. Because first wind-guiding structure 112 transversely opens, when opening first wind-guiding structure 112, can not have the dust to fall on the operation workman's body, make its maintenance process more convenient.
As shown in fig. 1 to fig. 3, the first wind guiding structure 112 may have a plurality of first wind guiding strips 1121 (in other embodiments, the first wind guiding structure 112 may also have only one wind guiding strip 1121), and the plurality of first wind guiding strips 1121 changes the size of the first wind guiding opening 111 by rotating around a central axis parallel to the length direction thereof. When the first wind guiding strip 1121 rotates, it can also guide the airflow guided out of the first wind guiding opening 111. In particular, when the first air guiding opening 111 has a plurality of openings, the first air guiding structures 112 with the same number of openings may be correspondingly arranged, and each first air guiding structure 112 is installed and arranged corresponding to one opening.
The second air guiding structure 122 is disposed at the second air guiding opening 121, and the second air guiding structure 122 is used for guiding the air flow ejected from the second air guiding opening 121 and changing the size of the opening of the second air guiding opening 121. Specifically, the second air guiding structure 122 also has a plurality of second air guiding strips arranged in parallel, and the plurality of second air guiding strips rotate around a central axis parallel to the length direction thereof to change the size of the second air guiding opening 121. Moreover, when the second air guiding strip rotates, the second air guiding strip can also guide the air flow guided out from the second air guiding opening 121.
The first wind guide strips 1121 and the second wind guide strips can be driven by a driving device, the driving device can be specifically a stepping motor, and a user adjusts the air outlet parameters so that the stepping motor controls the first wind guide strips 1121 or the second wind guide strips to rotate to the positions matched with the air outlet parameters.
When the air supply device is in the first working state, the first air guiding opening 111 is an air outlet, and the second air guiding opening 121 is an air inlet, so that the air intake of the ceiling fan 100 is not affected by the second air guiding structure 122, at this time, the second air guiding strip of the second air guiding structure 122 can rotate to the position where the second air guiding opening 121 is maximum, so that the air intake of the second air guiding opening 121 is maximum, and the stepping motor drives the first air guiding strip 1121 to rotate to the proper position according to the size of the required air outlet.
When the air supply device is in the second working state, the second air guiding opening 121 is an air outlet, and the first air guiding opening 111 is an air inlet, so that the air intake of the ceiling fan 100 is not affected by the first air guiding structure 112, at this time, the first air guiding strip 1121 of the first air guiding structure 112 may be rotated to a position where the first air guiding opening 111 is maximized, so that the air intake of the first air guiding opening 111 is maximized, and the stepper motor drives the second air guiding strip to rotate to a proper position according to the size of the required air outlet.
In a specific embodiment, the supporting members 170 are disposed between the top wall and the bottom wall 120 of the ceiling-suspended machine 100, and specifically, the number of the supporting members 170 may be three, the top wall of the ceiling-suspended machine 100 is connected to the upper ends of the supporting members 170, and the bottom wall 120 is connected to the lower ends of the supporting members 170, and the supporting members are used for limiting the distance between the top wall and the bottom wall 120. Meanwhile, a first air guiding opening 111 is defined between the support parts 170, the first air guiding structure 112 is further arranged between every two support parts 170, one end of the first air guiding structure 112 is hinged with one support part 170, and the other end of the first air guiding structure is clamped with the other adjacent support part 170. The support member 170 may also be used to connect a support column for lifting the ceiling-suspended machine, so that the gravity of the ceiling-suspended machine is transmitted to the support member 170 through the support column, and specifically, the support member 170 may be made of a material with high strength and rigidity to prevent the support member from deforming under stress.
Because the existing ceiling machine with the embedded four sides is mostly applied to commercial occasions such as markets, office buildings and the like, and the indoor unit of the household air conditioner is mostly of a cabinet air conditioner air duct hanging machine type and the like, the structural design of the three supporting parts 170 of the ceiling machine 100 in the embodiment can simultaneously replace various products (or commercial four-side embedded machines) of the existing indoor unit of the household air conditioner, and the purpose of adjusting indoor air in an energy-saving, efficient and comfortable manner is realized by adopting the ceiling mode of placing the ceiling machine in a closed space.
In order to achieve the purpose of changing the air supply direction in the ceiling fan 100, in a specific embodiment, the air supply device may include two fans, where the two fans blow air to the outside of the first air guide opening 111 and the second air guide opening 121 in a one-to-one correspondence manner, in a first operating state, the fan blowing air to the outside of the first air guide opening 111 is turned on, and in a second operating state, the fan blowing air to the outside of the second air guide opening 121 is turned on. In another specific embodiment, only one axial flow fan 140 may be provided, and the axial flow fan 140 may guide the heat exchange air flow in the air conditioning indoor unit out of the first air guiding opening 111 when rotating forward and guide the heat exchange air flow in the air conditioning indoor unit out of the second air guiding opening 121 when rotating backward (note that the specific rotating directions of the axial flow fan 140 are not limited above, and the "forward rotation" and the "reverse rotation" only indicate two mutually opposite rotating directions of the axial flow fan 140). When only one axial flow fan 140 is provided, the orientation position of the axial flow fan 140 can be turned over through a mechanical structure, so that the direction of the airflow generated after the axial flow fan 140 is started is changed. In one embodiment, some mechanical structure may be further provided to enable the blades of the axial flow fan 140 to rotate, so as to change the flow direction of the airflow after the axial flow fan 140 is turned on by rotating the blades of the axial flow fan 140 by a certain angle.
When the air supply device has two fans, preferably, the two fans are the axial flow fan 140 and the centrifugal fan 130, respectively. The centrifugal fan 130 is configured to eject the heat exchange airflow in the ceiling fan 100 through the first air guiding opening 111, and the axial flow fan 140 is configured to eject the heat exchange airflow in the ceiling fan 100 through the second air guiding opening 121. The axial flow fan 140 can better achieve the air supply purpose of ejecting the air flow in the vertical downward direction, and the centrifugal fan 130 can better achieve the air supply purpose of ejecting the air flow in the circumferential direction out of the first air guide opening 111.
The ceiling fan 100 further comprises a heat exchange component 150, the heat exchange component 150 is configured to exchange heat with air entering the ceiling fan 100, when the fan that injects the air flow to the outside of the first air guiding opening 111 is the centrifugal fan 130, in order to save the internal space of the ceiling fan 100, in an embodiment, the impeller 131 of the centrifugal fan 130 has a cavity with a downward opening in the center, the heat exchange component 150 is disposed in the cavity, and the axial flow fan 140 is disposed below the heat exchange component 150. Such a positional arrangement can make good use of the space inside the impeller 131 of the centrifugal fan 130. Specifically, in order to facilitate sufficient heat exchange between the air flow inside the ceiling suspended ceiling fan 100 and the heat exchange component 150, the heat exchange component 150 may be annular, and the central axis of the heat exchange component is parallel to the central axis of the impeller 131, so that the air flow generated by the axial flow fan 140 passes through the heat exchange component 150 in a direction parallel to the central axis of the heat exchange component 150, and thus, the ambient air and the heat exchange component 150 can perform sufficient heat exchange. In order to prevent the moisture condensed on the heat exchange member 150 from leaking to the axial flow fan 140, the diameter of the heat exchange member 150 may be larger than the diameter of the blades of the axial flow fan 140, and the blades of the axial flow fan 140 may be located at the center of the heat exchange member 150. In order to remove moisture generated on the heat exchange member 150, a ring-shaped drip tray 160 may be disposed below the heat exchange member 150. The middle of the annular water pan 160 is provided with a central hole, and the central hole is arranged corresponding to the second air guide opening 121 and used for guiding out air flow. The annular water pan 160 has an annular groove extending around the central hole, and the heat exchange member 150 is embedded in the annular groove, so that the moisture generated by the heat exchange member 150 falls into the annular groove, and the moisture stored in the annular groove is pumped out by other drainage devices, thereby effectively preventing the moisture in the ceiling-suspended machine 100 from leaking. In particular, when the illumination lamp 123 is provided on the bottom wall 120, the water tray 160 can also effectively protect the illumination lamp 123 on the bottom wall 120.
In order to prevent dust or other foreign matters in the environment from entering the ceiling fan 100, a filter screen may be disposed at the air inlet of the ceiling fan 100, and since the first air guiding opening 111 and the second air guiding opening 121 may both serve as the air inlet of the ceiling fan 100, the filter screen may be disposed at the first air guiding opening 111 and the second air guiding opening 121. Because the air outlet of the ceiling fan 100 is provided with the filter screen, the air outlet of the ceiling fan 100 is not smooth enough, when the first air guiding opening 111 is the air outlet, the filter screen can be arranged at the second air guiding opening 121, and the filter screen is not arranged at the first air guiding opening 111; when the second air guiding opening 121 is an air outlet, a filter screen is disposed at the first air guiding opening 111, and no filter screen is disposed at the second air guiding opening 121.
As shown in fig. 6 to 7, the present invention further provides an air supply control method for an air conditioning indoor unit in any of the above embodiments:
s110: acquiring a working mode of an indoor unit of an air conditioner;
s130: determining the air supply direction in the air-conditioning indoor unit according to the working mode;

That is, in different operation modes of the air-conditioning indoor unit, the air supply directions in the air-conditioning indoor unit are different, and the air supply direction mentioned above specifically refers to whether the heat exchange airflow in the air-conditioning indoor unit is ejected towards the first air guiding opening 111 or the second air guiding opening 121. When the heat exchange airflow is ejected towards the first air guiding opening 111, the first air guiding opening 111 is an air outlet, and the second air guiding opening 121 is an air inlet. When the heat exchange airflow is ejected towards the second air guiding opening 121, the second air guiding opening 121 is an air outlet, and the first air guiding opening 111 is an air inlet. Specifically, the operation modes of the indoor unit of the air conditioner may include a heating mode and a cooling mode, and after the operation mode of the indoor unit of the air conditioner is determined, controlling the air supply device to supply air in the determined air supply direction specifically includes:
s131: when the operation mode is the cooling mode, the air supply direction is a direction in which the heat exchange airflow in the air conditioning indoor unit is ejected toward the first air guide opening 111.
S133: when the operation mode is the heating mode, the air supply direction is a direction in which the heat exchange airflow in the air conditioning indoor unit is ejected toward the second air guide opening 121.
Namely, in the heating mode, the first air guiding opening 111 is an air inlet of the indoor unit of the air conditioner, and the second air guiding opening 121 is an air outlet of the indoor unit of the air conditioner. In the cooling mode, the first air guiding opening 111 is an air outlet of the indoor unit of the air conditioner, and the second air guiding opening 121 is an air inlet of the indoor unit of the air conditioner. As mentioned above, the above air outlet mode can make the heat exchange efficiency of the indoor unit of the air conditioner higher.
In order to adjust the size of the outlet air in the first air guiding opening 111 and the second air guiding opening 121, in an embodiment, the size of the first air guiding opening 111 and/or the size of the second air guiding opening 121 may be variable. Specifically, the first air guiding structure 112 may be disposed at the first air guiding opening 111, the second air guiding structure 122 may be disposed at the second air guiding opening 121, and the first air guiding structure 112 and the second air guiding structure 122 are described in detail above, and are not described herein again.
Because the bigger the air inlet of the air-conditioning indoor unit is, the more unobstructed the air inlet thereof is, in one embodiment, the air supply control method of the air-conditioning indoor unit further comprises the following steps:
s151: when the working mode of the indoor unit of the air conditioner is a heating mode, adjusting the first air guide mechanism to enable the opening of a first air guide opening 111 serving as an air inlet to be the largest;
s153: when the working mode of the indoor unit of the air conditioner is the cooling mode, the second air guide mechanism is adjusted to enable the opening of the second air guide opening 121 serving as the air inlet to be the largest.
The control method can keep the air inlet of the indoor unit of the air conditioner smoother.
In one embodiment, the first air guiding opening 111 and the second air guiding opening 121 are both provided with a filter screen for filtering dust or foreign matters in the air. The filter net corresponding to the first air guiding opening 111 can shield or open the first air guiding opening 111, and the filter net corresponding to the second air guiding opening 121 can shield or open the second air guiding opening 121. After the filter screen is arranged, the air supply control method of the indoor unit of the air conditioner further comprises the following steps:
s171: when the working mode is the heating mode, the filter screen corresponding to the first air guiding opening 111 shields the first air guiding opening 111, and the filter screen corresponding to the second air guiding opening 121 opens the second air guiding opening 121;
s173: when the operation mode is the cooling mode, the filter corresponding to the second air guiding opening 121 covers the second air guiding opening 121, and the filter corresponding to the first air guiding opening 111 opens the first air guiding opening 111.
That is, when the first air guiding opening 111 is the air outlet, the filter screen at the first air guiding opening 111 can be taken down (that is, the filter screen corresponding to the first air guiding opening 111 is opened with the first air guiding opening 111), so that the air inlet of the indoor unit of the air conditioner is smooth; the filter net at the second air guiding opening 121 is retained (i.e. the filter net corresponding to the second air guiding opening 121 covers the second air guiding opening 121), so as to filter the air flow guided into the second air guiding opening 121. When the second air guide opening 121 is an air outlet, the filter screen at the second air guide opening 121 can be taken down, so that air can smoothly enter the indoor unit of the air conditioner; the filter screen at the first air guiding opening 111 is reserved to filter the air flow guided into the first air guiding opening 111. Specifically, the filter screen can be manually or automatically removed. When the filter screen is automatically taken down, the filter screen can be connected with the driving device, when the filter screen is required to be filtered, the driving device drives the filter screen to rotate to the position covering the first air guide opening 111 or the second air guide opening 121, and when the filter screen is required to be taken down, the driving device drives the filter screen to rotate to the position not covering the first air guide opening 111 or the second air guide opening 121.
The specific air supply direction of the air supply device is as follows:
s191: when the indoor unit of the air conditioner is in a heating mode, the air supply device supplies air to the outside of the second air guide opening 121;
s193: when the indoor unit of the air conditioner is in the cooling mode, the air supply device supplies air to the outside of the first air guide opening 111.
The air supply device may include two fans, and the two fans supply air to the outside of the first air guide opening 111 and the second air guide opening 121 in a one-to-one correspondence manner. The air supply device may include only the axial flow fan 140, and the axial flow fan 140 changes the air supply direction by the forward and reverse rotation of the impeller. The specific working mode of providing two fans or only one axial flow fan 140 has been described above, and is not described herein.
When the air conditioning indoor unit is the ceiling fan 100 described above, the centrifugal fan 130 and the axial flow fan 140 may be arranged to supply air, the centrifugal fan 130 is used to supply air to the outside of the first air guide opening 111, and the axial flow fan 140 is used to supply air to the outside of the second air guide opening 121. The heat exchange member 150 in the ceiling fan 100 is provided inside the impeller of the centrifugal fan 130 so that the ambient air introduced into the air conditioner indoor unit can be sufficiently heat-exchanged.
