Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner indoor unit, an air conditioner and a control method thereof. Background Art

[0002] When the air conditioner is cooling, the temperature inside the indoor unit will drop significantly, and the air guide plate is usually located near the air outlet of the indoor unit. If the indoor air temperature is high, the temperature on the surface of the air guide plate will be lower than the dew point temperature of the indoor air; similarly, in a high humidity environment, the water vapor content in the air is high. When the air conditioner is cooling, the temperature on the surface of the air guide plate drops, making it easier for the water vapor in the air to reach saturation, thus condensing into water on the surface of the air guide plate. The condensed water dripping onto the ground will make the ground slippery, increasing the risk of users falling and posing a safety hazard.

[0003] How to properly handle the condensed water produced by the air guide plate to prevent it from dripping onto the ground is a technical problem that urgently needs to be solved. Summary of the invention

[0004] Therefore, the present invention provides an air-conditioning indoor unit, an air conditioner and a control method thereof, which can solve the technical problem in the prior art that condensed water on the air guide plate drips onto the ground.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0033] 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.

[0034] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0035] See also Figure 1-7As shown, an air conditioner indoor unit 1 provided by the present invention comprises an air outlet 101 and an air guide plate 2, wherein the air guide plate 2 has a first working position for closing the air outlet 101 and a second working position for opening the air outlet 101, the air guide plate 2 is provided with a water storage chamber 201, the air guide plate 2 comprises a windward surface 3 facing the air outlet 101, the windward surface 3 is provided with a first hole 301, and the first hole 301 penetrates into the water storage chamber 201;

[0036] The air conditioner indoor unit 1 is further provided with a pumping member 401 , and the windward surface 3 is further provided with a second hole 302 communicating with the water storage chamber 201 . When the air guide plate 2 is in the first working position, the inlet 4011 of the pumping member 401 is communicated with the second hole 302 .

[0037] When the air conditioner is in cooling mode, the air guide plate 2 is in the second working position. Figure 1 As shown, the condensed water generated on the windward surface 3 of the air guide plate 2 enters the water storage chamber 201 through the first hole 301, thereby preventing the condensed water from dripping onto the ground. When the water in the water storage chamber 201 needs to be discharged, the air guide plate 2 is in the first working position, as shown in the fermented bean curd 2. At this time, the air conditioner is no longer cooling (shutdown or heating), and the pumping member 401 works to pump out the condensed water in the water storage chamber 201 from the second hole 302, and discharges it to the outside through a special drain pipe, or to a special water storage container indoors.

[0038] When the air guide plate 2 is in the first working position (closing the air outlet 101), it is connected to the inlet 4011 of the water pumping member 401 for drainage. On the one hand, it is more intuitive to observe from the outside whether the water storage chamber 201 is draining. On the other hand, closing the air outlet 101 can reduce the propagation of noise when the water pumping member is working, thereby reducing the noise in the room. Since the water storage chamber 201 is provided, the water storage chamber 201 has a certain temperature insulation effect, and the cold air flowing out of the air outlet 101 has less effect on the leeward side (the side opposite to the windward side 3) of the air guide plate 2, thereby reducing or avoiding the generation of condensed water on the leeward side of the air guide plate.

[0039] Furthermore, the water pumping member 401 may be a water pump.

[0040] Furthermore, the first holes 301 are micropores with very small pore sizes, such as 1-3 mm in diameter. The number of the first holes 301 is large and evenly distributed on the windward surface 3 , and the condensed water generated on the windward surface 3 can quickly enter the water storage chamber 201 from these micropores.

[0041] Preferably, Figure 1 As shown, a composite water absorbent 402 is disposed in the water storage cavity 201 , and the composite water absorbent 402 can absorb water at low temperatures and release water at high temperatures.

[0042] After the condensed water enters the water storage chamber 201 through the first hole 301, it can be absorbed by the composite water absorbent 402, so that the condensed water is prevented from flowing out of the first hole 301 and the second hole 302 after reaching a certain water level; after the condensed water is absorbed by the composite water absorbent 402, the condensed water can be stored in the water storage chamber 201 more stably, and the condensed water can be prevented from overflowing from the first hole 301 and the second hole 302 due to vibration of the wind guide plate 2. The composite water absorbent 402 can also absorb the condensed water in the first hole 301, so that the condensed water does not stay in the first hole 301 under the action of tension, hindering the condensed water on the windward surface 3 from entering the water storage chamber 201 through the first hole 301.

[0043] When the composite water absorbent member 402 is full of water (the composite water absorbent member 402 can no longer absorb water), the air guide plate 2 moves to the first working position, and the composite water absorbent member 402 is heated, and the composite water absorbent member 402 extracts water after heating, and the extracted water flows to the second hole 302 under the action of gravity, and at the same time, the air in the water extraction member 401 extracts the extracted water out of the water storage chamber 201 from the second hole 302.

[0044] Furthermore, a water storage chamber may be provided between the second hole 302 and the water storage chamber 201 , and the water precipitated from the composite water absorbent member 402 will first flow into the water storage chamber and be collected, and then be pumped out by the water pumping member 401 .

[0045] In another embodiment, a water-absorbing sponge is provided in the water storage chamber 201. Condensed water enters the water storage chamber 201 through the first hole 301 and is absorbed and stored by the water-absorbing sponge. When the water-absorbing sponge absorbs enough condensed water, the air guide plate 2 moves to the first working position, and the inlet 4011 of the water-drawing member 401 performs a suction action relative to the second hole 302. The water in the water-absorbing sponge precipitates under the action of the pressure difference and flows to the second hole 302, and is then drawn out by the water-drawing member 401.

[0046] Preferably, the composite water absorbent 402 is composed of a metal organic framework and a polymer material.

[0047] MOFs (metal organic framework) is a material with a highly porous structure and a large specific surface area. The material has strong hydrophilicity, especially in a low humidity environment, and has good water separation when the temperature exceeds 80°C; specifically, it can efficiently absorb water at low temperatures and separate water at high temperatures (80 degrees is optimal). The material is set in the water storage chamber 201, absorbs condensed water at low temperatures, and separates condensed water at high temperatures, thereby achieving absorption and storage of condensed water and separation and discharge of condensed water.

[0048] Preferably, Figure 1 As shown, an electric heating element 403 is also provided in the water storage chamber 201 .

[0049] By setting the electric heating element 403, when condensed water needs to be precipitated, the electric heating element 403 can be turned on to heat the composite water absorbent 402. In this way, the composite water absorbent 402 can be easily controlled to facilitate the conversion between low-temperature absorbed water and high-temperature precipitated water.

[0050] Preferably, the air outlet 101 includes relative upper and lower sides, and when the air guide plate 2 is in the first working position, the end of the lower side close to the air outlet 101 is the lower end 202, and the end of the upper side close to the air outlet 101 is the upper end 203; the water storage chamber 201 includes a lower chamber close to the lower end 202 and an upper chamber close to the upper end 203; the first hole 301 is connected to the upper chamber, and the second hole 302 is connected to the lower chamber.

[0051] Since the upper chamber and the lower chamber are connected, the second hole 302 is connected to the lower chamber, and the condensed water can flow to the lower chamber under the action of gravity, so that the pumping member 402 can complete the pumping work.

[0052] The width distance between the upper end 203 and the lower end 202 is L, and the width of the lower cavity is about 1 / 4L. The electric heating element 403 can be an electric heating wire, which can be arranged in the lower cavity and in contact with the composite water absorbent element 402, so that the composite water absorbent element 402 can be better heated.

[0053] Furthermore, the second hole 302 is also arranged within a range of about 1 / 4L from the lower end 202, and the first hole 301 is arranged on the windward surface 3 in an area of ​​about 3 / 4L near the upper end 203; in this way, there is no second hole in the area of ​​about 1 / 4L from the lower end 202, and the condensed water can be temporarily stored in the area of ​​about 1 / 4L from the lower end 202, which is convenient for the pumping member 401 to extend into the water outlet chamber 201 to pump water, and also avoids the precipitated water from overflowing due to failure to be pumped out in time.

[0054] Preferably, the composite water absorbent member 402 is disposed in the upper cavity, a flexible water absorbent member is disposed in the lower cavity, and the inlet 4011 of the water drawer 401 is inserted into the second hole 302 and in contact with the flexible water absorbent member.

[0055] A flexible water-absorbing member is arranged in the lower cavity and is opposite to the second hole 302, so that when the air guide plate 2 moves to the first working position, the inlet 4011 of the water-drawing member 401 is connected with the second hole 302 to draw water from the flexible water-absorbing member. When there is less condensed water in the water storage cavity 201, if there is no flexible water-absorbing member, the less condensed water cannot be effectively drawn out by the water-drawing member 401, and the condensed water is not fixed in the water storage cavity 201 and will splash out due to the vibration of the air guide plate 2. By providing a flexible water-absorbing member, water that could not be pumped out by the water-pumping member 401 will be absorbed by the flexible water-absorbing member and fixed in the flexible water-absorbing member, thus not only avoiding the splashing of condensed water; when the inlet 4011 of the water-pumping member 401 contacts the flexible water-absorbing member, the water-pumping member 401 can also pump out the absorbed condensed water from the flexible water-absorbing member, thereby more thoroughly pumping out the condensed water in the water storage chamber 201; it also avoids the whistling sound that occurs when pumping out less condensed water.

[0056] Preferably, Figure 3 and Figure 4 As shown, a sealing ring 406 is disposed around the second hole 302 .

[0057] By setting the sealing ring 406, as Figure 3-Figure 6 As shown, the inlet 4011 of the water pump can form a sealing structure with the second hole 302, which is conducive to the water pumping member 401 to suck condensed water from the second hole 302; when a flexible water absorbent member is provided, it is conducive to forming a pressure difference on the flexible water absorbent member (the closer the area is to the inlet 4011 of the water pumping member 401, the smaller the pressure), which is conducive to absorbing condensed water from the flexible water absorbent member.

[0058] Specifically, the specific setting position of the sealing ring 406 may include: 1. The sealing ring 406 is arranged around the second hole 302 on the windward surface 3. In this case, the inlet 4011 of the pumping member 401 does not need to go deep into the second hole 302, and only needs to abut against the sealing ring 406 for sealing. 2. The sealing ring 406 is arranged in the second hole 302 and fits on the inner wall of the second hole 302. In this case, the inlet of the pumping member 401 needs to extend into the second hole 302, and the outer wall surface of the inlet of the pumping member 401 is sealed with the sealing ring 406. 3. The setting of the sealing ring 406 includes the above-mentioned two situations. The sealing ring 406 is set on the windward surface 3 and extends into the second hole 302. At this time, the cross-section of the sealing ring 406 is similar to an inverted "L" shape, with one horizontal part fitting the windward surface 3 and one vertical part extending into the second hole 302. At this time, an annular plate is provided at one end of the inlet 4011 of the pumping member 401, and the inlet 4011 extends into the second hole 302 and is squeezed and sealed with the "vertical part", and the annular plate squeezes the "horizontal part" and the sealing ring fitted on the windward surface 3 for squeezing and sealing.

[0059] The present invention further provides an air conditioner, comprising a control module and the air conditioner indoor unit 1 .

[0060] By setting up the control module, the air guide plate 2, the water pumping element 401, the temperature sensor, the humidity sensor 404 and the electric heating element 403 can work.

[0061] The present invention also provides a control method for an air conditioner, such as Fig. 9 As shown, the control method includes: when the air conditioner is in cooling mode and the water in the water storage chamber 201 needs to be discharged, firstly controlling the air guide plate 2 to move to the first working position, and then starting the pumping member 401.

[0062] First, the air guide plate 2 is controlled to move to the first working position, at which time the air conditioner no longer cools and does not continue to generate condensed water, and then the pumping member 401 is started to extract the stored condensed water from the water storage chamber 201.

[0063] Furthermore, the second hole 302 is provided with a baffle that can open or close the second hole 302. When the air guide plate 2 is in the first working position, the baffle opens the second hole 302, and when the air guide plate 2 is in the second working position, the baffle closes the second hole 302, thereby preventing condensation water from flowing out of the second hole 302 when the air guide plate 2 is in the second working position.

[0064] Preferably, when a composite water absorbent member 402, a humidity sensor 404 and a temperature sensor are provided in the water storage chamber 201, the control method further comprises: a first judgment method for determining whether the water pumping member 401 is started and a second judgment method for determining whether the water pumping member 401 is stopped. The first judgment method is: detecting the humidity value of the composite water absorbent member 402 by the humidity sensor 404, and when the humidity value is higher than a first value, determining that the water in the water storage chamber 201 needs to be discharged; and the second judgment method is: when the humidity value of the composite water absorbent member 402 detected by the humidity sensor 404 is lower than a third value, determining that the water pumping member 401 is stopped.

[0065] The first judgment method is: the humidity value of the composite water absorbent 402 is detected by the humidity sensor 404. When the humidity value is higher than the first value, it means that the composite water absorbent 402 is basically saturated and can no longer absorb condensed water. At this time, the water absorbed by the composite water absorbent 402 needs to be precipitated and discharged from the water storage chamber 201. Logically, it is determined that the water in the water storage chamber 201 needs to be discharged at this time; the air guide plate 2 moves to the first working position, and the pumping member 401 is controlled to start. The second judgment method is: when the humidity of the composite water absorbent 402 is lower than the third value, it means that the composite water absorbent 402 absorbs very little condensed water, and the condensed water on the air guide plate 2 will not have the risk of dripping to the ground, and the pumping member 401 can be stopped. The third value is less than the first value.

[0066] Furthermore, in addition to judging the humidity of the composite water absorbent member 402, the method for judging whether the water pumping member 401 is activated should also judge the temperature of the composite water absorbent member 402. The temperature value of the composite water absorbent member 402 is detected by a temperature sensor. When the temperature value reaches a second value (a temperature sensor 405 is arranged in the water storage chamber to detect the temperature of the composite water absorbent member 402, for example, higher than 80°C, but not higher than 82°C. If the temperature is too high, the air guide plate 2 will be deformed by heat) and lasts for a preset time, condensed water begins to precipitate from the composite water absorbent member 402 at a faster speed and flows to the lower chamber for collection; within the preset time period, part of the condensed water has been collected in the lower chamber, and at this time, the water pumping member 401 is activated to extract the precipitated condensed water.

[0067] Preferably, an electric heating element 403 is provided in the water storage chamber 201, and the control method further comprises a method for heating the composite water absorbent member 402, the heating method comprising: when the air guide plate 2 is in the first working position, turning on the electric heating element 403 and setting it at a preset temperature value, and when the humidity of the composite water absorbent member 402 is lower than a third value, stopping the heating element;

[0068] and / or,

[0069] The air conditioner is controlled to start a heating function.

[0070] When the air guide plate 2 is in the first working position, the condensed water on the composite water absorbent 402 needs to be precipitated, and the electric heating element 403 is turned on to heat the composite water absorbent 402, and the preset temperature of the electric heating element 403 is 80°C; the composite water absorbent 402 is accelerated to heat up to the second value, and when the composite water absorbent 402 is composed of MOFs (metal organic framework) polymer material, the second value can be set to 80°C. When the humidity of the composite water absorbent 402 is lower than the third value, it is not necessary to heat and precipitate water, and the heating can be stopped; further, the heating of the composite water absorbent 402 is stopped first, and after about half a minute, the water extraction element 401 is stopped to ensure that the condensed water can be fully extracted.

[0071] To further quickly heat up the composite water absorbent 402 , when the air guide plate 2 is in the first working position, the air conditioner starts the heating function, and the heat is blown toward the windward surface 3 through the first hole 301 by the fan blade of the indoor unit 1 to heat the composite water absorbent 402 .

[0072] The working process of the air conditioner is as follows: the air conditioner turns on the cooling mode, the air guide plate 2 moves to the second working position, the humidity sensor 404 is turned on, the cold air flows through the windward surface 3 of the air guide plate 2 and generates condensed water on the windward surface 3 (the temperature of the composite water absorbent member 402 in the water storage chamber 201 is relatively low under the action of the cold air, which is convenient for absorbing condensed water), the condensed water enters the water storage chamber 201 through the first hole 301, the condensed water entering the water storage chamber 201 is absorbed by the low-temperature composite water absorbent member 402, the humidity sensor 404 continuously detects the humidity of the composite water absorbent member 402, and when the humidity of the composite water absorbent member 402 reaches the first value, the composite water absorbent member 402 can no longer absorb more condensed water, and the water on the composite water absorbent member 402 needs to be precipitated and discharged from the water storage chamber 201. At this time, the air conditioner is no longer cooling, the air guide plate 2 moves to the first working position, the inlet 4011 of the water pumping member 401 is opposite to the second hole 302, the electric heating member 403 is turned on to heat the composite water absorbent member 402 (the heating temperature value is set to 80°C) and continues for a preset time (the air conditioner can also be controlled to turn on the heating function at the same time), and then the water pumping member 401 is turned on (there is no need to wait for the temperature of the composite water absorbent member 402 to rise to the second value to avoid condensed water overflow); when the humidity of the composite water absorbent member 402 is lower than the third value, the electric heating member 403 stops heating, and the water pumping member 401 continues to work for about half a minute and then stops. The water pumped out of the water storage chamber 201 by the water pumping member 401 is discharged to a special container outdoors or indoors through the drain pipe. After completing the above process, the air conditioner can turn on the cooling mode again, and the air guide plate 2 moves to the second working position, and the cycle is repeated.

[0073] Through the above-mentioned structural scheme and control method, the condensed water is prevented from gathering inside the air conditioner indoor unit 1, the growth of bacteria and other microorganisms is reduced, and it is beneficial to ensure the sanitary quality of indoor air. At the same time, the condensed water will not drip onto the indoor floor, thus preventing the indoor floor from being slippery, and further preventing the user from falling due to the slippery floor, thereby improving the user experience.

[0074] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
