Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning air supply system. Background Art

[0002] When existing household air conditioners are used for heating in winter, the air inlet and outlet of the air conditioner are installed on the roof. When in use, the hot air has a lower density than the cold air, causing the warm air to circulate over the room. The temperature difference between the upper and lower parts is too large, and users generally feel hot in the head and cold in the feet. In actual use scenarios, in order to alleviate the heating effect, users often increase the air speed of the air conditioner and raise the air temperature to let the warm air rush down. Due to the high wind speed in the room, it is easy to cause dry mouth and dry skin for users.

[0003] However, the existing humidification equipment is an independent humidifier. Since the air inlet and outlet are both set on the machine, the air passing through the humidifier is often limited to the vicinity of the humidifier. The humidified air is difficult to reach the far corners of the room, resulting in uneven humidity in different areas of the room, resulting in a poor user experience. Utility Model Content

[0004] The main purpose of the present application is to provide an air-conditioning air supply system to solve the problem in the prior art that in an air-conditioned room, the humidifier humidifies unevenly in different areas of the room, resulting in a poor user experience.

[0005] According to one aspect of the utility model, there is provided an air conditioning air supply system, comprising:

[0006] An air conditioner main body, the air conditioner main body comprising an indoor unit, the indoor unit is used to be installed on the top of the room, and the indoor unit comprises an air inlet and an air outlet;

[0007] An air supply assembly, the air supply assembly comprising an air supply channel, the air supply channel extending in the height direction of the room to at least transport air at the bottom of the room to the air inlet;

[0008] A humidifying component, wherein the humidifying component is arranged at the air inlet, the humidifying component comprises a water supply mechanism and a water absorption mechanism, the water absorption mechanism comprises a mounting frame and a water absorption part arranged in the mounting frame, the mounting frame is provided with a channel connected to the air inlet, and the water supply mechanism is used to supply water to the water absorption part.

[0009] Furthermore, the water absorbing part includes a sponge layer or a hydrophilic membrane layer.

[0010] Furthermore, the water supply mechanism comprises:

[0011] a water tank, wherein the water absorption portion is at least partially disposed in the water tank; and / or,

[0012] a water spraying portion, the water spraying portion being arranged on the top of the water absorbing portion; and / or,

[0013] A water storage tank is arranged on the top of the water absorption part, and an opening is arranged on one side of the water storage tank facing the water absorption part, and a control valve is arranged at the opening.

[0014] Further, a first water pump is installed at the bottom of the water tank, and the first water pump is connected to the water spraying part through a first pipe; and / or,

[0015] The air conditioning and air supply system further comprises a first water source and a second water pump, wherein the second water pump is connected between the water tank and the first water source via a second pipe; and / or,

[0016] The air conditioning and air supply system further includes a second water source and a third water pump, and the third water pump is connected between the second water source and the water spraying part through a third pipeline.

[0017] Furthermore, a plurality of holes are provided on the water absorbing portion and / or the mounting frame.

[0018] Furthermore, the water spraying part is a plurality of spray heads, and the spray heads extend along the length direction of the mounting frame and are sequentially arranged above the mounting frame.

[0019] Furthermore, a filter screen is arranged on the mounting frame.

[0020] Furthermore, the air supply assembly also includes a fan, and the fan is arranged in the air supply channel or at the end thereof.

[0021] Furthermore, the air conditioner main body includes a control circuit board, and the control circuit board is electrically connected to the fan to control the fan.

[0022] Furthermore, the indoor unit includes a bellows, the bottom of which is provided with the air inlet, and the air supply passage is connected to the bellows.

[0023] In the utility model, by providing an air supply channel on the air supply assembly, when the air conditioner body is working, the air supply channel can transport the cold air at the bottom of the room to the air inlet of the indoor unit. At this time, the warm air flowing out of the air outlet of the indoor unit can sink to the bottom of the room, instead of just circulating at the top of the room. However, in the process of using the air conditioner, it is easy to cause the user to have dry skin and dry mouth. In the prior art, the humidifier is used alone, and the improvement effect on the room is not good. The present application proposes to set a humidification assembly at the air inlet, wherein the humidification assembly includes a water supply mechanism and a water absorption mechanism, and water is supplied to the water absorption mechanism through the water supply mechanism. When the air conditioning system is started, the air will pass through the water absorption part on the mounting frame. The water absorption part that has been fully soaked will vaporize the water molecules on the water absorption part due to air convection and the negative pressure in the air supply channel. The vaporized water molecules can enter the indoor unit through the air supply channel and be sent to the top of the room, and circulate through the air in the room, thereby improving the body feeling in the whole room.

[0024] That is to say, the present application uses an air supply component and a humidification component to deliver the water vapor at the bottom of the room through the humidification component to the indoor unit at the top, which can not only speed up the circulation of air in the room, but also improve the comfort in the room. Specifically, by adding a humidification component at the air inlet, the water molecules on the humidification component evaporate into the air supply channel due to air convection, and enter the top of the room through the indoor unit through the flow direction of the air conditioning air supply system. Because the air conditioning air supply system circulates fully and evenly in the room, the water vapor can reach every corner of the room, thereby improving the body feeling in the room.

In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] As mentioned in the background technology, in order to alleviate the heating effect during winter heating, existing household air conditioners often increase the air speed and temperature of the air conditioner to let the warm air rush down. Due to the high wind speed in the room, it is easy to cause users to have dry mouth and dry skin. Some users use humidification equipment to humidify the room, but the existing humidification equipment is an independent humidifier. Since the air inlet and the air outlet are both set on the machine, the air passing through the humidifier is often limited to the vicinity of the humidifier. The humidified air is difficult to reach the farther corners of the room, resulting in uneven humidity in different areas of the room, resulting in a poor user experience. To this end, the present application proposes a new air conditioning and air supply system, and the air conditioning and air supply system of the present application will be described in detail below in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 3 As shown, according to an embodiment of the present application, an air conditioning air supply system is provided, which includes an air conditioning main body, an air supply component 20 and a humidification component 30.

[0036] Specifically, the air conditioner body in this embodiment includes an indoor unit 10, which is used to be installed at the top of the room 60, and the indoor unit 10 includes an air inlet 11 and an air outlet 12; the air supply component 20 includes an air supply channel 21, and the air supply channel 21 extends along the height direction of the room 60 to at least be used to transport the air at the bottom of the room 60 to the air inlet 11; the humidification component 30 is arranged at the air inlet 11, and the humidification component 30 includes a water supply mechanism 31 and a water absorption mechanism 32, and the water absorption mechanism 32 includes a mounting frame 321 and a water absorption part 322 arranged in the mounting frame 321, and the mounting frame 321 is provided with a channel 33 connected to the air inlet 11, and the water supply mechanism 31 is used to supply water to the water absorption part 322.

[0037] In the present application, since the air supply assembly 20 is provided with an air supply channel 21, when the air conditioner body is working, the air supply channel 21 can deliver the cold air at the bottom of the room 60 to the air inlet 11 of the indoor unit 10. At this time, the warm air flowing out of the air outlet 12 of the indoor unit 10 can sink to the bottom of the room 60, instead of just circulating at the top of the room 60. The flow direction of the air in the room 60 can be referred to. Figures 1 to 3As shown by the arrow in . However, in the process of using the air conditioner, it is easy to cause the user to have dry skin and dry mouth and the like. The humidifier in the prior art is used alone, and the improvement effect on the room 60 is not good. The present application proposes to set a humidifying component 30 at the air inlet 11, wherein the humidifying component 30 includes a water supply mechanism 31 and a water absorption mechanism 32, and water is supplied to the water absorption mechanism 32 through the water supply mechanism 31. When the air conditioning air supply system is started, the air will pass through the water absorption part 322 on the mounting frame 321. The water absorption part 322 that has been fully soaked is vaporized due to convection with the air and the negative pressure in the air supply channel 21. The vaporized water molecules can enter the indoor unit 10 along the air supply channel 21 and be sent to the top of the room 60, and circulate through the air in the room 60, thereby improving the body feel in the entire room 60.

[0038] That is to say, the present application uses the air supply component 20 and the humidification component 30 to send the water vapor at the bottom of the room 60 through the humidification component 30 to the indoor unit 10 at the top, which can not only speed up the circulation of air in the room 60, but also improve the comfort in the room 60. Specifically, by adding a humidification component 30 at the air inlet 11, the water molecules on the humidification component 30 evaporate into the air supply channel 21 due to air convection, and enter the top of the room 60 through the indoor unit 10 through the flow direction of the air conditioning air supply system. Because the air conditioning air supply system circulates fully and evenly in the room 60, the water vapor can reach every corner of the room 60, so that the body feeling in the room 60 becomes better.

[0039] See also Figures 1 to 3As shown, a water absorption part 322 is provided on the mounting frame 321, wherein the water absorption part 322 can be a sponge layer or a hydrophilic film layer, or a silica gel layer, a cotton wool layer, etc. Optionally, the shape of the mounting frame 321 can be a rectangular cavity structure, a circular cavity structure or other cavity structures, etc. In the present embodiment, it is preferred to set the shape of the mounting frame 321 to a rectangular cavity structure, which has a simple structure, and when it is connected to the air inlet 11 through the channel 33 and when the hydrophilic film layer is installed on the mounting frame 321, the operation is also simple. In the present application, it is preferred to set the water absorption part 322 to a hydrophilic film layer. Due to the limitations of traditional water absorption structures such as sponge layers, silica gel layers, and cotton wool layers, the water absorption rate is only 20-40 times of its own weight, which is far from meeting people's needs. The hydrophilic film layer contains polar groups with a greater affinity for water, which can quickly moisten the film layer and keep it moist for a long time when it comes into contact with water. Of course, in other embodiments of the present application, the water absorption portion 322 can also be other structures, as long as it can absorb water and remain soaked for a long time when the air conditioning and air supply system is working. In this embodiment, the hydrophilic film layer can be fixed to the mounting frame 321 by screws, buckles and other structures to ensure that the hydrophilic film layer is firmly installed to prevent it from falling and affecting the operation of the air conditioning system. The shape of the hydrophilic film layer can be rectangular, circular, triangular, etc. In the present application, the shape of the hydrophilic film layer is preferably rectangular, so that a larger surface area can be provided to form convection with the air, thereby providing sufficient water molecules when the air conditioning and air supply system is started.

[0040] In the present application, the water supply mechanism 31 can be at least one of the water tank 311, the water spraying part 312 or the water storage tank 70, or a combination of the water tank 311 and the water spraying part 312, or a combination of the water tank 311 and the water storage tank 70. In the present embodiment, there are at least three situations for the positional relationship between the water supply mechanism 31 and the water absorption part 322: (1) the water absorption part 322 is at least partially disposed in the water tank 311; (2) the water spraying part 312 is disposed on the top of the water absorption part 322; (3) the water storage tank 70 is disposed on the top of the water absorption part 322, and an opening is disposed on one side of the water storage tank 70 facing the water absorption part 322, and a control valve (not shown in the figure) is disposed at the opening. It is worth noting that the position of the water absorption part 322 in contact with water in the water tank 311 should not be too high. If it is too high, it will be difficult for air to form convection with the water on the hydrophilic film layer on the water absorption part 322 due to the water seal when the air conditioning and air supply system is working, resulting in less water molecules being provided; the position should not be too low either. If it is too low, it will take a long time for the water absorption part 322 to fully soak the hydrophilic film layer through its own capillary action, affecting the use of the air conditioning and air supply system. In this application, the water supply mechanism 31 has two functions: one is to supply water to the water absorption part 322 installed on the mounting frame 321, and the other is to receive the water flowing down from the water spray part 312 or the water storage tank 70 after working, which can not only prevent water from being discharged arbitrarily in the room 60, but also realize the recycling of water and avoid wasting water resources.

[0041] See again Figures 1 to 3 As shown, in this embodiment, the water supply mechanism 31 can supply water in a variety of ways. The first way is that a first water pump 313 is installed at the bottom of the water tank 311, and the water pump 313 is connected to the water spraying part 312 through a first pipe 50 to realize the recycling of water; the second way of supplying water is to provide a first water source (not shown in the figure) and a second water pump (not shown in the figure), and the second water pump is connected between the water tank 311 and the first water source through a second pipe. Through the pores and capillary action of the water absorption part 322, the water absorption part 322 can be automatically fully soaked; the third way is to provide a second water source (not shown in the figure) The third water pump is connected between the second water source and the water spraying part 312 through a third pipe (not shown in the figure), so as to prevent the water absorbing part 322 from contacting with the water collected in the water tank 311, and to prevent the water absorbing part 322 from generating odor due to long-term contact with water without timely replacement, thereby reducing the comfort in the room 60; the fourth method is to set a water storage tank 70 on the top of the mounting frame 321, and set a water outlet 71 at the bottom of the water storage tank 70, and set a related flow regulating device and control valve in the water storage tank 70 to control the water output and water output. Among them, the water tank 311 installed at the bottom of the water absorbing part 322 can not only receive the water from the water storage tank 70, but also provide water to the water absorbing part 322. The water molecules in the water absorbing part 322 can be adsorbed on the entire water absorbing part 322 from bottom to top through capillary action. In this embodiment, the water supply method can be used alone or in combination. In this way, when a sudden water outage occurs, another method can be used to improve the comfort of room 60 after the air conditioning system is working.

[0042] Furthermore, a plurality of pores are provided on the water absorption part 322 or the mounting frame 321. The plurality of pores provided on the water absorption part 322 are conducive to the convection between the water molecules on the water absorption part 322 and the air in the room 60, and ensure that the air can pass through the water absorption part 322, so that the air conditioning and air supply system can work better. In addition, the plurality of pores on the water absorption part 322 can ensure that the water molecules in the water absorption part 322 can actively move from bottom to top through capillary action, ensure that the entire water absorption part 322 can be completely soaked, and can provide sufficient water vapor when the air conditioning and air supply system is working, increase the comfort in the room 60, and improve the comfort of the user. Due to the different water supply methods, when the water supply method adopted is the fourth method mentioned above, a plurality of water inlet holes 72 need to be provided on the mounting frame 321 to ensure that the water absorption part 322 can be fully soaked during water supply.

[0043] Furthermore, if the water supply method adopted is the first or third method mentioned above, it is necessary to set a water spray part 312 on the top of the mounting frame 321, wherein there are multiple nozzles on the water spray part 312, and the number of nozzles can be 1, 2, 3, 4, 5, etc. In actual production and processing, the number of nozzles is arranged according to actual needs. The nozzles extend along the length direction of the mounting frame 321 and are arranged in order above the mounting frame 321. Under this water supply method, there is a certain distance between the water spray part 312 and the mounting frame 321, so that the water absorption part 322 can be fully soaked when spraying water. Of course, in the embodiments of the present application, when the above two methods are used to supply water, pores can be set on the mounting frame 321, or pores can not be set, as long as the water absorption part 322 can be fully soaked.

[0044] In the present application, a channel 33 connected to the air supply channel 21 is provided on the mounting frame 321, and through the channel 33, the mounting frame 321 and the air supply channel 21 are closed and connected, so that a negative pressure environment can be formed when the air conditioning air supply system is working, and water molecules and air can smoothly enter the air supply channel 21. In addition, a filter screen (not shown in the figure) is provided on the mounting frame 321, so that impurities in the room 60 can be prevented from being sucked into the air supply channel 21 due to the negative pressure of the air supply channel 21, thereby blocking the air supply channel 21 and affecting the entire air conditioning air supply system.

[0045] In order to increase the flow rate of air in the room 60, the air supply assembly 20 of the present application further includes a fan 40, which is arranged in the air supply channel 21 or at the end thereof. When the fan 40 is working, the cold air at the bottom of the room 60 can be quickly sucked into the air supply channel 21 through the water absorption part 322 and transported to the air inlet 11. Optionally, the fan 40 in this embodiment can be set to one, or two or more. Figures 1 to 3 FIG. 2 shows a case where there is only one fan 40 .

[0046] Furthermore, the air conditioner body includes a control circuit board, which is electrically connected to the fan 40 to control the fan 40. That is to say, in this embodiment, the control switch of the fan 40 is integrated with the control circuit board of the air conditioner body. In this way, the user can control the fan 40 according to actual needs, so as to speed up the flow speed of the air in the room 60 at the right time, and the structure is simple and easy to operate.

[0047] In this embodiment, the indoor unit 10 includes a bellows 13, the air inlet 11 is arranged at the bottom of the bellows 13, and the air supply channel 21 is connected to the bellows 13, so as to facilitate the delivery of air at the bottom of the room 60 to the bellows 13, so that the air in the room 60 can be effectively circulated.

[0048] According to the above embodiments, the air conditioning and air supply system of the present application can at least achieve the following technical effects:

[0049] (1) In the present application, an air supply component is provided to transport the air at the bottom of the room to the air inlet, which can speed up the circulation of the air in the room, make it easier for the hot air at the top of the room to sink to the bottom of the room, and quickly equalize the temperature in the room;

[0050] (2) The present application sets a humidifying component at the air inlet, so that the air and the water absorption part on the humidifying component can form convection, accelerate the evaporation of water molecules on the humidifying component, and the evaporated water molecules will be sent to the top of the room through the air conditioner indoor unit along the flow direction of the air conditioning air supply system. Since the air conditioning air supply system can make the air flow in the room fully and evenly circulate, the evaporated water molecules are also evenly distributed, making the room feel better;

[0051] (3) The present application sets a fan in the air supply channel, which can speed up the air flow in the room, so that the water molecules that are more suitable for evaporation can fully reach all parts of the room, improving the situation in the prior art that the humidifier can only improve the comfort of the room locally.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
