Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and particularly relates to an air conditioner indoor unit, an air conditioner and a control method thereof. BACKGROUND

[0002] When the air conditioner is cooling, the temperature inside the indoor unit will decrease significantly, and the air deflector is usually located near the air outlet of the indoor unit. If the indoor air temperature is high, the temperature of the surface of the air deflector 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 of the surface of the air deflector decreases, so that the water vapor in the air is more likely to reach a saturated state, thereby condensing water on the surface of the air deflector. The condensed water drops falling to the ground can make the ground slippery, increasing the risk of users falling and posing a safety hazard.

[0003] How to reasonably handle the condensed water generated by the air deflector to avoid the condensed water from falling to the ground is a technical problem that needs to be solved at present. SUMMARY

[0004] Therefore, the present application provides an air conditioner indoor unit, an air conditioner and a control method thereof, which can solve the technical problem of condensed water on the air deflector falling to the ground in the prior art.

[0005] The first aspect of the present application provides an air conditioner indoor unit, comprising an air outlet and an air deflector, the air deflector having a first working position closing the air outlet and a second working position opening the air outlet, the air deflector being provided with a water storage cavity, the air deflector comprising a windward surface facing the air outlet, the windward surface being provided with a first hole, the first hole penetrating into the water storage cavity;

[0006] The air conditioner indoor unit is further provided with a water pumping element, and the windward surface is further provided with a second hole communicating with the water storage cavity, and when the air deflector is in the first working position, the inlet of the water pumping element communicates with the second hole.

[0007] In some embodiments, a composite water absorbing element is arranged in the water storage cavity, which can absorb water at low temperature and release water at high temperature.

[0008] In some embodiments, the composite water absorbing element is composed of a metal organic framework and a high molecular material.

[0009] In some embodiments, the water storage cavity is further provided with an electric heating element.

[0010] In some embodiments, the air outlet includes an upper side and a lower side opposite to each other. When the air guide plate is in the first working position, the end near the lower side of the air outlet is the lower end, and the end near the upper side of the air outlet is the upper end. The water storage cavity includes a lower cavity near the lower end and an upper cavity near the upper end. The first hole communicates with the upper cavity, and the second hole communicates with the lower cavity. In some embodiments, the composite water-absorbing element is disposed in the upper cavity, and a flexible water-absorbing element is disposed in the lower cavity. The inlet of the water-drawing element is inserted into the second hole and contacts the flexible water-absorbing element.

[0011] In some embodiments, a sealing ring is provided around the second hole.

[0012] Secondly, the present invention provides an air conditioner, including a control module and the indoor unit of the air conditioner.

[0013] Thirdly, the present invention also provides a control method for an air conditioner, the control method comprising: when the air conditioner is in cooling mode and the water in the water storage chamber needs to be discharged, first controlling the air guide plate to move to a first working position, and then starting the water pumping component.

[0014] In some embodiments, the water storage cavity is provided with a composite water-absorbing component and a humidity sensor. The control method further includes: a first determination method for whether the water pumping component is started and a second determination method for whether the water pumping component is stopped. The first determination method is: the humidity value of the composite water-absorbing component is detected by the humidity sensor. When the humidity value is higher than a first value, it is determined that the water pumping component needs to be started. The second determination method is: when the humidity value of the composite water-absorbing component detected by the humidity sensor is lower than a third value, it is determined that the water pumping component is stopped.

[0015] In some embodiments, an electric heating element is provided in the water storage cavity, and the control method further includes a heating method for the composite water-absorbing element, the heating method including: when the air guide plate is in the first working position, turning on the electric heating element and setting it to a preset temperature value; and when the humidity of the composite water-absorbing element is lower than a third value, stopping the heating element.

[0018] This invention incorporates a water storage chamber on an air guide plate. Condensation generated on the windward side of the air guide plate enters the storage chamber through a first hole and is stored, preventing it from dripping onto the ground. When water needs to be drained, the air guide plate closes its outlet, and a pump removes the water from the storage chamber. This effectively prevents condensation on the air guide plate from dripping onto the ground. Attached Figure Description

DETAILED DESCRIPTION

[0031] Clearly, the embodiments described are only a part of all the embodiments of the present application, rather than all the embodiments. The following description of at least one example embodiment is merely illustrative in nature and does not limit the present application or its applications or uses in any way. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0032] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship are generally based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, without the opposite description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0033] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawings is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the example term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0034] In addition, it should be noted that the use of "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore it cannot be understood as a limitation on the scope of protection of the present application.

[0035] For reference Figures 1-7As shown, the present invention provides an air conditioner indoor unit 1, including an air outlet 101 and an air guide plate 2. The air guide plate 2 has a first working position with the air outlet 101 closed and a second working position with the air outlet 101 open. The air guide plate 2 is provided with a water storage cavity 201. The air guide plate 2 includes a windward surface 3 facing the air outlet 101. The windward surface 3 is provided with a first hole 301, which extends into the water storage cavity 201.

[0036] The indoor unit 1 of the air conditioner is also provided with a water pump 401, and the windward surface 3 is also provided with a second hole 302 that connects to the water storage cavity 201. When the air guide plate 2 is in the first working position, the inlet 4011 of the water pump 401 is connected to the second hole 302.

[0037] When the air conditioner is cooling, the air guide plate 2 is in the second working position, such as... Figure 1 As shown, the condensate generated on the windward side 3 of the air guide plate 2 enters the water storage chamber 201 through the first hole 301, preventing the condensate from dripping onto the ground. When the water in the water storage chamber 201 needs to be drained, the air guide plate 2 is in the first working position, as shown in Figure 2. At this time, the air conditioner stops cooling (stops or heats), and the water pump 401 works to extract the condensate from the water storage chamber 201 through the second hole 302 and discharge 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 (air outlet 101 closed), it connects with the inlet 4011 of the water pump 401 for drainage. On the one hand, it allows for more direct observation from the outside whether the water storage chamber 201 is being drained. On the other hand, closing the air outlet 101 reduces the transmission of noise during the operation of the water pump, thus reducing indoor noise. Because of the water storage chamber 201, which provides some insulation, the cold air flowing from the air outlet 101 has less impact on the leeward side of the air guide plate 2 (the side opposite to the windward side 3), thus reducing or preventing condensation on the leeward side of the air guide plate.

[0039] Furthermore, the pumping component 401 can be a water pump.

[0040] Furthermore, the first hole 301 is a micropore with a very small diameter, such as 1 to 3 mm. There are many first holes 301 and they are evenly distributed on the windward side 3. The condensate generated on the windward side 3 can quickly enter the water storage chamber 201 through these micropores.

[0041] Preferred, such as Figure 1 As shown, a composite water-absorbing component 402 is provided inside the water storage cavity 201. The composite water-absorbing component 402 can absorb water at low temperatures and release water at high temperatures.

[0042] Through the composite water absorption piece 402, the condensed water entering the water storage cavity 201 through the first hole 301 can be absorbed by the composite water absorption piece 402, so that the condensed water is prevented from flowing out of the first hole 301 and the second hole 302 when reaching a certain water level; after the condensed water cup is absorbed by the composite water absorption piece 402, the condensed water can be more stably stored in the water storage cavity 201, and the condensed water is prevented from overflowing from the first hole 301 and the second hole 302 due to vibration of the deflector 2 and the like. The composite water absorption piece 402 can also absorb the condensed water in the first hole 301, so as to prevent the condensed water from staying in the first hole 301 under the action of tension and hindering the condensed water on the windward surface 3 from entering the water storage cavity 201 through the first hole 301.

[0043] When the composite water absorption piece 402 is full of water (the composite water absorption piece 402 cannot absorb water any more), the deflector 2 is moved to the first working position, the composite water absorption piece 402 is heated, and water is separated out from the composite water absorption piece 402 after being heated, and the separated water flows to the second hole 302 under the action of gravity, and the water is pumped out of the water storage cavity 201 by the water pump 401.

[0044] Further, a water storage cavity can be arranged between the second hole 302 and the water storage cavity 201, and the water separated out from the composite water absorption piece 402 flows into the water storage cavity first and is then pumped out by the water pump 401.

[0045] In another embodiment, a water absorption sponge is arranged in the water storage cavity 201. The condensed water entering the water storage cavity 201 through the first hole 301 is absorbed and stored by the water absorption sponge. When the water absorption sponge absorbs enough condensed water, the deflector 2 is moved to the first working position, the inlet 4011 of the water pump 401 is opposite to the second hole 302 to perform a pumping action, the water in the water absorption sponge is separated out under the action of pressure difference and flows to the second hole 302, and is then pumped out by the water pump 401.

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

[0047] The MOFs (metal organic framework) is a material with a highly porous structure and a large specific surface area, has strong hydrophilicity, especially in a low humidity environment, and has good water separation at a temperature exceeding 80℃; specifically, can efficiently absorb water at low temperature and separate water at high temperature (optimal at 80 degrees). The material is arranged in the water storage cavity 201, absorbs condensed water at low temperature, separates out condensed water at high temperature, and thus realizes absorption and storage of the condensed water and separation and discharge of the condensed water.

[0048] Preferably, as shown in Figure 1 The water storage cavity 201 further comprises an electric heating piece 403.

[0049] By setting the electric heating element 403, when condensed water needs to be precipitated, the electric heating element 403 is turned on to heat the composite water absorption element 402.

[0050] Preferably, the air outlet 101 comprises opposite upper and lower sides, when the air baffle 2 is in the first working position, one end close to the lower side of the air outlet 101 is the lower end 202, and one end close to the upper side of the air outlet 101 is the upper end 203; the water storage cavity 201 comprises a lower cavity close to the lower end 202 and an upper cavity close to the upper end 203; the first hole 301 is in communication with the upper cavity, and the second hole 302 is in communication with the lower cavity.

[0051] Since the upper cavity and the lower cavity are in communication, the second hole 302 is in communication with the lower cavity, and the condensed water can flow to the lower cavity under the action of gravity, so that the water pumping element 401 can complete the water pumping work.

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

[0053] Further, 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 in a region of about 3 / 4L close to the upper end 203 of the windward surface 3; in this way, there is no second hole in the region of about 1 / 4L from the lower end 202, and the condensed water can be temporarily stored in the region of about 1 / 4L from the lower end 202, so as to facilitate the water pumping element 401 to extend into the water storage cavity 201 to pump water, and also avoid the precipitated water from overflowing due to not being pumped in time.

[0054] Preferably, the composite water absorption element 402 is arranged in the upper cavity, a flexible water absorption element is arranged in the lower cavity, and the inlet 4011 of the water pumping element 401 is inserted into the second hole 302 and in contact with the flexible water absorption element.

[0055] The flexible water absorbing part is arranged in the lower cavity, and is opposite to the second hole 302, so that when the air deflector 2 moves to the first working position, the inlet 4011 of the water pumping part 401 is in communication with the second hole 302 for pumping water, and water is absorbed from the flexible water absorbing part. When the condensed water in the water storage cavity 201 is less, if there is no flexible water absorbing part, the less condensed water cannot be effectively pumped out by the water pumping part 401, and the part of the condensed water is not fixed in the water storage cavity 201, and can splash out due to the vibration of the air deflector 2. By arranging the flexible water absorbing part, the water that cannot be pumped out by the water pumping part 401 is absorbed by the flexible water absorbing part and fixed in the flexible water absorbing part, so that the condensed water is not splashed out, and when the inlet 4011 of the water pumping part 401 contacts the flexible water absorbing part, the water pumping part 401 can pump out the condensed water absorbed in the flexible water absorbing part, and the condensed water in the water storage cavity 201 can be pumped out more completely, and the howling sound generated when the condensed water is less and pumped out is avoided.

[0056] Preferably, as shown in Figure 3 and Figure 4 The second hole 302 is provided with a sealing ring 406 around the second hole 302.

[0057] By arranging the sealing ring 406, as shown in Figures 3-6 The inlet 4011 of the water pumping part can form a sealing structure with the second hole 302, which is beneficial to the water pumping part 401 for pumping condensed water from the second hole 302, and when the flexible water absorbing part is arranged, it is beneficial to form a pressure difference on the flexible water absorbing part (the closer to the inlet 4011 of the water pumping part, the smaller the pressure), and it is beneficial to absorb the condensed water from the flexible water absorbing part.

[0058] Specifically, the specific arrangement position of the sealing ring 406 can include: one, the sealing ring 406 is arranged on the windward surface 3 around the second hole 302, at this time, the inlet 4011 of the water pumping part 401 can not be inserted into the second hole 302, and only needs to abut and seal with the sealing ring 406. Two, the sealing ring 406 is arranged in the second hole 302 and is attached to the inner wall of the second hole 302, at this time, the inlet of the water pumping part 401 needs to be inserted into the second hole 302, and the outer wall surface of the inlet of the water pumping part 401 is sealed with the sealing ring 406. Three, the arrangement of the sealing ring 406 includes the above two cases, the sealing ring 406 is arranged on the windward surface 3 and is inserted into the second hole 302, at this time, the cross section of the sealing ring 406 is similar to an inverted “L” shape, one horizontal part is attached to the windward surface 3, and one vertical part is inserted into the second hole 302, at this time, one end of the inlet 4011 of the water pumping part 401 is provided with a ring-shaped plate, the inlet 4011 is inserted into the second hole 302 and is pressed and sealed with the “one vertical” part, and the ring-shaped plate is pressed and sealed with the sealing ring attached to the windward surface 3.

[0059] The application also provides an air conditioner, which comprises a control module and the air conditioner indoor unit 1.

[0060] By setting the control module, the working of the air deflector 2, the water pumping element 401, the temperature sensor, the humidity sensor 404 and the electric heating element 403 are controlled.

[0061] The application also provides a control method for the air conditioner, as shown in the figure, the control method comprises: Figure 9 When the air conditioner is in the cooling mode and the water in the water storage cavity 201 needs to be discharged, first control the air deflector 2 to move to the first working position, and then start the water pumping element 401.

[0062] First control the air deflector 2 to move to the first working position, at this time the air conditioner no longer cools and will not continue to produce condensed water, and then start the water pumping element 401 to extract the stored condensed water from the water storage cavity 201.

[0063] Further, the second hole 302 is provided with a baffle capable of opening or closing the second hole 302, when the air deflector 2 is in the first working position, the baffle opens the second hole 302, when the air deflector 2 is in the second working position, the baffle closes the second hole 302; avoid the condensed water from flowing out of the second hole 302 when the air deflector 2 is in the second working position.

[0064] Preferably, when the water storage cavity 201 is provided with the composite water absorbing element 402, the humidity sensor 404 and the temperature sensor, the control method further comprises: a first judgment method of whether the water pumping element 401 is started and a second judgment method of whether the water pumping element 401 is stopped, the first judgment method is: detecting the humidity value of the composite water absorbing element 402 by the humidity sensor 404, when the humidity value is higher than the first value, it is determined that the water in the water storage cavity 201 needs to be discharged; the second judgment method is: when the humidity value of the composite water absorbing element 402 detected by the humidity sensor 404 is lower than the third value, it is determined that the water pumping element 401 is stopped.

[0065] The first judgment method is: detecting the humidity value of the composite water absorbing element 402 by the humidity sensor 404, when the humidity value is higher than the first value, it means that the composite water absorbing element 402 is basically saturated and cannot absorb condensed water any more, at this time the water absorbed by the composite water absorbing element 402 needs to be discharged and discharged from the water storage cavity 201, in logic, at this time it is determined that the water in the water storage cavity 201 needs to be discharged; the air deflector 2 moves to the first working position and the water pumping element 401 is started. The second judgment method is: when the humidity of the composite water absorbing element 402 is lower than the third value, it means that the composite water absorbing element 402 absorbs little condensed water, and the condensed water on the air deflector 2 will not have the risk of dripping to the ground, so the work of the water pumping element 401 can be stopped. The third value is less than the first value.

[0066] Further, the method for judging the starting of the water pumping device 401 should also judge the temperature of the composite water absorbing device 402 in addition to judging the humidity of the composite water absorbing device 402. The temperature value of the composite water absorbing device 402 is detected by the temperature sensor. When the temperature value reaches a second value (the temperature of the composite water absorbing device 402 is detected by the temperature sensor 405 arranged in the water storage cavity, for example, higher than 80℃, but cannot be higher than 82℃, if the temperature is too high, it will cause the deflector 2 to be deformed by heat) and lasts for a preset time length, the condensed water starts to precipitate from the composite water absorbing device 402 at a faster speed and flows to the lower cavity for collection; during the preset time length, the lower cavity has collected part of the condensed water, at this time, the water pumping device 401 starts to pump out the precipitated condensed water.

[0067] Preferably, the water storage cavity 201 is provided with an electric heating device 403, and the control method further comprises a heating method for the composite water absorbing device 402, the heating method comprising: when the deflector 2 is in the first working position, the electric heating device 403 is turned on and is set at a preset temperature value, and when the humidity of the composite water absorbing device 402 is lower than a third value, the heating device is stopped.

[0068] and / or,

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

[0070] When the deflector 2 is in the first working position, the condensed water on the composite water absorbing device 402 needs to be precipitated, the electric heating device 403 is turned on to heat the composite water absorbing device 402, the preset temperature of the electric heating device 403 is 80℃, the temperature of the composite water absorbing device 402 is accelerated to the second value, when the composite water absorbing device 402 is composed of MOFs (metal organic framework) polymer material, the second value can be set to 80℃. When the humidity of the composite water absorbing device 402 is lower than the third value, there is no need to heat to precipitate water, and the heating is stopped; further, the heating of the composite water absorbing device 402 is stopped first, and after about half a minute, the water pumping device 401 is stopped to work, so as to ensure that the precipitated condensed water can be fully pumped out.

[0071] In order to further accelerate the temperature rise of the composite water absorbing device 402, when the deflector 2 is in the first working position, the air conditioner starts the heating function, and the heat is blown to the composite water absorbing device 402 through the first hole 301 under the action of the fan blade of the indoor unit 1.

[0072] The working process of the air conditioner is as follows: the air conditioner is started in the refrigeration mode, the air deflector 2 is moved to the second working position, the humidity sensor 404 is started, the cold air flows through the windward surface 3 of the air deflector 2 and condensate water is generated on the windward surface 3 (the composite water absorption member 402 in the water storage cavity 201 is low in temperature under the action of the cold air, so as to facilitate the absorption of the condensate water), the condensate water enters the water storage cavity 201 through the first hole 301, the condensate water entering the water storage cavity 201 is absorbed by the low-temperature composite water absorption member 402, the humidity sensor 404 continuously detects the humidity of the composite water absorption member 402, when the humidity of the composite water absorption member 402 reaches a first value, the composite water absorption member 402 cannot absorb more condensate water, and the water on the composite water absorption member 402 needs to be drained and discharged from the water storage cavity 201. At this time, the air conditioner is no longer in the refrigeration mode, the air deflector 2 is moved to the first working position, the inlet 4011 of the water pump 401 is opposite to the second hole 302, the electric heating member 403 is started to heat the composite water absorption member 402 (the heating temperature value is set to 80 DEG C) and is continuously started for a preset time (at this time, the air conditioner can also be controlled to start the heating function), and then the water pump 401 is started (without waiting for the temperature of the composite water absorption member 402 to rise to a second value, so as to avoid the overflow of the condensate water); when the humidity of the composite water absorption member 402 is lower than a third value, the electric heating member 403 stops heating, and the water pump 401 continues to work for about half of the time and then stops. The water pumped out of the water storage cavity 201 by the water pump 401 is discharged to the outdoor or a special container in the indoor. After the above process is completed, the air conditioner can be started in the refrigeration mode again, the air deflector 2 is moved to the second working position, and the cycle is performed.

[0073] Through the above structure scheme and control method, the condensate water is prevented from gathering in the indoor unit 1 of the air conditioner, the breeding of bacteria and other microorganisms is reduced, the sanitary quality of the indoor air is beneficially ensured. At the same time, the condensate water will not drip to the floor in the indoor, the floor in the indoor is prevented from being wet and slippery, and then the user is prevented from falling down due to the wet and slippery floor. The experience of the user is improved.

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

[0075] The above only describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The above only describes the preferred embodiments of the present application and should not be used to limit the present application.
