Description

Technical Field

[0001] The present application relates to the field of air conditioning, and in particular to an air conditioner. Background Art

[0002] When the air conditioner is running, air will enter the air conditioner from the air inlet, and then be blown out from the air outlet after heat exchange through the heat exchanger, thus achieving heat exchange. The air inlet of the air conditioner is generally set directly above the air conditioner, which makes the heat exchanger in the air conditioner easy to accumulate dust, and the heat exchanger is easy to breed bacteria in a high temperature and high humidity environment, making the air blown out of the air outlet have a musty smell, affecting the user experience and health.

[0003] In the related art, in order to reduce the dust from entering the air inlet of the air conditioner, an air inlet baffle assembly is often provided at the air inlet of the air conditioner. When the air conditioner is idle, the air inlet baffle assembly is closed to prevent dust from entering the air conditioner through the air inlet; when the air conditioner is working, the air inlet baffle assembly is opened to expose the air inlet. However, when the air conditioner is idle, although the air inlet baffle assembly can prevent dust from entering the air conditioner by closing the air inlet, dust will accumulate on the air inlet baffle assembly. When the air conditioner is started, the wind force of the air inlet will blow the dust and other foreign objects attached to the surface of the air inlet baffle assembly into the air conditioner. That is, after the air inlet baffle assembly is opened, the dust will fall into the air conditioner again, which cannot fundamentally play the role of dust prevention for the air conditioner.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] The embodiment of the present application provides an air conditioner, which is used to adjust the temperature, humidity, etc. of the environment. The air conditioner can be a cooling-only air conditioner or a cooling-heating dual-purpose air conditioner, and the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, or a window air conditioner, etc., which is not specifically limited in the embodiment of the present application. It should be noted that the air conditioner can be an integrated air conditioner structure or a separated air conditioner structure, wherein the separated air conditioner structure includes an indoor unit and an outdoor unit, and the integrated air conditioner structure integrates all system components in an integral chassis.

[0032] In the embodiment of the present application, the air conditioner comprises: an air conditioner body and a suspension plate assembly, wherein the suspension plate assembly is used to cooperate with the air inlet on the air conditioner body to close or open the air inlet. Figure 1 As shown, the air conditioner body includes a housing 100 and a main control board (not shown in the figure) located on the housing 100, the housing 100 has an air inlet 101, and the air conditioner body also includes a magnetic force generating device 200 disposed at the air inlet 101, and the magnetic force generating device 200 is electrically connected to the main control board. The suspension board assembly includes a suspension board 400 and a magnetic element 500 disposed on the suspension board 400. Among them, the magnetic element 500 on the suspension board 400 is arranged opposite to the magnetic force generating device 200, and the main control board is used to control the power-on state of the magnetic force generating device 200, so that the suspension board assembly covers the air inlet 101 or suspends above the air inlet 101.

[0033] Exemplarily, if the main control board controls the magnetic force generating device 200 to be powered on, the magnetic force generating device 200 can generate a force that repel each other with the magnetic element 500, so that the suspension plate assembly is suspended at a set height above the air inlet 101, thereby opening the air inlet 101; if the first main control board controls the magnetic force generating device 200 to be powered off, the force that repel each other with the magnetic element 500 generated by the magnetic force generating device 200 will gradually disappear, causing the suspension plate assembly to descend and cover the air inlet 101, thereby closing the air inlet 101.

[0034] It can be understood that, due to the introduction of the suspension plate assembly that cooperates with the air inlet 101 of the air conditioner, based on the control of the power-on state of the magnetic force generating device 200, it is possible to switch between the suspension plate assembly floating above the air inlet 101 when the air conditioner is running and covering the air inlet 101 when the air conditioner is stopped. In this way, dust and other foreign objects when the air conditioner is idle can be prevented from entering the interior of the air conditioner, and the wind force of the air inlet 101 after the air conditioner is started can be prevented from bringing dust and other foreign objects blocked outside into the interior of the air conditioner, thereby effectively improving the dust-proof effect of the air conditioner.

[0035] Here, the magnetic force generating device 200 can be an electromagnet, that is, a device that generates electromagnetism based on power supply, for example, a conductive coil matching its power is wound around the outside of the iron core, and the conductive coil becomes magnetic like a magnet after power supply. It should be noted that the electromagnet has the characteristics of generating magnetism when power is supplied and disappearing magnetism after power is cut off. Based on the above characteristics of the electromagnet, it can cooperate with the magnetic element 500 disposed on the suspension board 400 to realize the displacement switching of the suspension board assembly by using the effect of mutually repelling magnetic force.

[0036] For example, there are multiple magnetic force generating devices 200, which are arranged at intervals along the outer periphery of the air inlet 101. The number of magnetic elements 500 disposed on the suspension board 400 is the same as the number of magnetic force generating devices 200, and the two are arranged in a one-to-one correspondence. In this way, based on multiple sets of paired magnetic force generating devices 200 and magnetic elements 500, stable switching control of the suspension board assembly between opening the air inlet 101 and closing the air inlet 101 can be achieved.

[0037] In an application example, Figure 1 As shown, the air inlet 101 is located at the top of the housing 100 and is rectangular, the suspension board 400 is a rectangular structure with an area larger than the air inlet 101, and four magnetic force generating devices 200 are arranged at the top of the housing 100 and at the four corners of the rectangle. In the power-on state, the four magnetic force generating devices 200 can cooperate with the four magnetic elements 500 arranged oppositely on the suspension board 400 to generate an upward force at the four corners of the suspension board 400, so that the suspension board 400 is stably suspended at a set height above the air inlet 101. Exemplarily, the set height can be controlled based on the magnetic force of the electromagnet, for example, it can be between 30 mm (millimeter) and 50 mm, thereby meeting the air intake demand of the air inlet 101 when the air conditioner is working.

[0038] For example, Figure 1 As shown, the air conditioner body further includes a light emitting element 600 disposed at the air inlet 101 . The light emitting element 600 is electrically connected to a main control board, and the main control board is used to control the light emitting state of the light emitting element 600 .

[0039] It should be noted that the embodiment of the present application can achieve an auxiliary effect of night lighting by introducing a light-emitting element 600 at the air inlet 101, which can be coordinated with the suspension board assembly.

[0040] Exemplarily, the main control board is used to control the lighting state of the light-emitting element 600 based on the current operating state of the air conditioner; wherein the lighting state is partitioned based on one or more of the following: the lighting color of the light-emitting element, the number of lights emitted by the light-emitting element, and the lighting frequency of the light-emitting element.

[0041] Exemplarily, the light emitting element 600 may be an annular light strip arranged along the circumference of the air inlet 101 , and the light emitting state may be enriched based on the annular light strip to enhance the human-computer interaction experience.

[0042] It should be noted that the lighting state of the embodiment of the present application can be distinguished based on one of the above-mentioned lighting color, lighting quantity and lighting frequency, and can also be distinguished based on a combination of the above-mentioned multiple types. For example, in an application example, if the main control board determines that the air conditioner is in a cooling operation state, the light-emitting element 600 is controlled to display a blue light; if it is determined that the air conditioner is in a heating operation state, the light-emitting element 600 is controlled to display a yellow light; if it is determined that the air conditioner is in a fault state, the light-emitting element 600 is controlled to display a red light. In this way, the current operating state of the air conditioner can be indicated based on the lighting state of the light-emitting element 600, which is conducive to improving the user experience.

[0043] For example, Figure 2 As shown, the main control board 300 includes a processor 301 and a power supply switching circuit 302. The processor 301 is used to drive the power supply switching circuit 302 to supply power to the magnetic force generating device 200 based on the power-on instruction of the air conditioner, and to drive the power supply switching circuit 302 to disconnect the power supply of the magnetic force generating device 200 based on the power-off instruction of the air conditioner.

[0044] It is understandable that the processor 301 responds to the power-on command of the air conditioner and drives the power supply switching circuit 302 to supply power to the magnetic force generating device 200. Then, the magnetic force generating device 200 can generate a force that mutually repels the magnetic element 500, so that the suspension board assembly is suspended at a set height above the air inlet 101, thereby opening the air inlet 101. The processor responds to the power-off command of the air conditioner and drives the power supply switching circuit 302 to disconnect the power supply of the magnetic force generating device 200. Then, the force that mutually repels the magnetic element 500 generated by the magnetic force generating device 200 will gradually disappear, so that the suspension board assembly descends and covers the air inlet 101, thereby closing the air inlet 101. Thus, the intelligent control of the suspension board 400 to open or close the air inlet 101 following the operating state of the air conditioner is realized.

[0045] Exemplarily, the power supply switching circuit 302 is also used to supply power to the light-emitting element 600, wherein the processor 301 is also used to drive the power supply switching circuit 302 to increase the power supply opening of the light-emitting element 600 from zero to the rated power supply opening at a set power supply opening adjustment rate based on the power-on instruction.

[0046] Here, the rated power supply opening can be understood as the maximum power supply opening of the light emitting element 600. For example, the power supply switching circuit 302 can adjust the power supply opening of the light emitting element 600 based on pulse width modulation (PWM). Exemplarily, assuming that the power supply opening of the light emitting element 600 includes K levels (for example, 256 levels), and the time for the suspension board 400 to rise to the set height after the magnetic force generating device 200 is powered is T milliseconds, then the set power supply opening adjustment rate can be K / T level / millisecond, that is, every 1 millisecond, the opening is increased by K / T level until the power supply opening of the light emitting element 600 increases to the rated power supply opening. In this way, the light emitting brightness of the light emitting element 600 can change with the rising process of the suspension board, so that the user can perceive the opening process of the air inlet 101 of the air conditioner through the light emitting brightness of the light emitting element 600.

[0047] For example, Figure 2 As shown, the main control board 300 also includes: a light intensity detection circuit 303 connected to the processor 301, and the processor 301 is also used to drive the power supply switching circuit 302 to adjust the power supply opening of the light emitting element 600 based on the light intensity value detected by the light intensity detection circuit 303.

[0048] The light intensity detection circuit 303 can adopt a detection circuit based on a photoresistor. In this way, the processor 301 can obtain the light intensity of the current environment after the air conditioner is turned on, and drive the power supply switching circuit 302 to adjust the power supply opening of the light emitting element 600 based on the light intensity, so as to achieve a control effect of associating the light brightness of the light emitting element 600 with the light intensity of the current environment. For example, if the power supply opening of the light emitting element 600 is positively correlated with the light intensity of the current environment, that is, the lower the light intensity, the smaller the power supply opening of the light emitting element 600. In this way, the defect of affecting the user's sleep at night due to the excessive light of the light emitting element 600 can be effectively avoided, thereby improving the user experience.

[0049] Exemplarily, the processor 301 is further configured to drive the power supply switching circuit 302 to supply power to the light emitting element 600 at a rated power supply opening based on the lighting instruction.

[0050] Here, the lighting instruction can be sent by the user based on the remote control. In this way, after receiving the lighting instruction, the processor 301 can drive the power supply switching circuit 302 to supply power to the light-emitting element 600 at the rated power supply opening, that is, the light-emitting element 600 is illuminated at the luminous brightness corresponding to the rated power supply opening, without adjusting the power supply opening based on the light intensity of the current environment, thereby meeting the auxiliary lighting needs. In this way, the light-emitting element 600 can indicate the operating status of the air conditioner and be compatible with the auxiliary lighting function.

[0051] For example, Figure 3 As shown, the inner wall surface of the air inlet 101 has a set inclination angle, and the light-emitting element 600 is an annular light strip arranged on the inner wall surface of the air inlet 101, so that the annular light strip emits light along the set inclination angle; the bottom surface of the suspension board 400 has a convex portion 401 for reflecting the emitted light.

[0052] It should be noted that the annular light strip emits light along the set tilt angle, which can better project the light onto the convex portion 401 of the suspension board 400 and enhance the light display effect. For example, the set tilt angle can be an angle of 30 to 60 degrees with the horizontal plane.

[0053] Exemplarily, the outer surface of the convex portion 401 of the suspension board 400 is a matte surface. For example, the surface of the convex portion 401 can be matte treated by a spraying method or a mechanical treatment method in the related art to obtain a matte surface. Among them, the matte treatment can be understood as a special method to make the surface present a delicate, soft, and matte effect, which is mainly achieved by forming tiny bumps on the surface to produce a scattered reflection effect and reduce the surface reflectivity, so that the matte surface can appear softer under light.

[0054] The operation process of the air conditioner is explained below with reference to an application example.

[0055] This application example takes a split-type air conditioner as an example, in which the suspension plate assembly is arranged in conjunction with the air inlet of the indoor unit. Figure 4 As shown, the operation process of the air conditioner in this application example includes:

[0056] Step 401, turning on the air conditioner.

[0057] It should be noted that when the air conditioner is in standby mode or turned off, the suspension board assembly is in a closed state, that is, the suspension board assembly includes the air inlet of the indoor unit, thereby preventing dust and other impurities from entering the indoor unit and avoiding dust accumulation on the evaporator.

[0058] When the indoor unit MCU (ie, the aforementioned processor) receives a power-on command sent by the remote controller, it drives the power supply switching circuit to supply power to the annular light strip at the air inlet to open the air inlet.

[0059] Step 402, the suspension board slowly rises, and the brightness of the light strip is adjusted according to the rising time.

[0060] Here, the floating board will slowly rise under the repulsive force of the paired magnetic generating devices and magnetic elements, and the annular light strip will cooperate with the rising movement of the floating board, and the brightness will gradually increase from dark to brightest.

[0061] Exemplarily, assuming that the power supply opening of the annular light strip includes K levels (for example, it can be 256 levels), the time it takes for the suspension board to rise to the set height after the magnetic generating device supplies power is T milliseconds (ms), and the set power supply opening adjustment rate can be K / T level / millisecond, that is, the opening is increased by K / T level every 1 millisecond. The specific opening adjustment includes the following steps 403 to 405.

[0062] Step 403 , determine whether the delay time reaches 1 ms, if not, wait until the delay time reaches 1 ms, if yes, execute step 404 .

[0063] Step 404: the brightness opening is increased by K / T.

[0064] Step 405, determine whether the accumulated time reaches T, if not, return to step 402, if yes, execute step 406.

[0065] Step 406 , determining whether the delay time reaches T1 , if not, continue waiting until the delay time reaches T1 , and execute step 407 .

[0066] Here, when the suspension board rises to the highest point (ie, the set height), the photoresistor adjustment control program can be entered after the waiting time T1 is set.

[0067] Step 407, determine whether to start the lighting function, if not, execute step 408.

[0068] Here, if the indoor unit MCU determines that the lighting instruction instructing auxiliary lighting is not received, it determines that the lighting function is not started, and then executes step 408.

[0069] Step 408, enter the photosensitivity adjustment brightness control program.

[0070] Here, the photosensor can obtain the light intensity of the current environment. The indoor unit MCU drives the power switching circuit 302 to adjust the power opening of the ring light strip based on the light intensity, thereby achieving a control effect in which the luminous brightness of the ring light strip is associated with the light intensity of the current environment, thereby preventing the ring light strip from being too bright at night and affecting the user's sleep.

[0071] Step 409, determine whether the air conditioner is turned off, if not, return to step 408, if so, execute step 410.

[0072] Step 410, the hoverboard lands and the annular light strip is turned off.

[0073] Here, if the indoor unit MCU receives a shutdown command from the air conditioner, it drives the power supply switching circuit to disconnect the power supply to the magnetic generating device and the annular light strip, the suspension board descends to close the air inlet, and the annular light strip is powered off.

[0074] It should be noted that during the operation of the air conditioner, the indoor unit MCU can also switch the lighting state of the ring-shaped light strip based on the operating state of the air conditioner. For example, if it is determined that the air conditioner is in a cooling operation state, the ring-shaped light strip is controlled to display a blue light. If it is determined that the air conditioner is in a heating operation state, the ring-shaped light strip is controlled to display a yellow light. If it is determined that the air conditioner is in a fault state, the ring-shaped light strip is controlled to display a red light. In this way, the current operating state of the air conditioner can be indicated based on the lighting state of the ring-shaped light strip, which is beneficial to improving the user experience.

[0075] Exemplarily, the auxiliary lighting function of the air conditioner can also be realized based on the annular light strip. In an application example, the operation process of the air conditioner can also include:

[0076] Step 411, receiving a remote control command instructing auxiliary lighting.

[0077] Here, the indoor unit MCU can receive the remote control command of the auxiliary lighting sent by the user via the remote control.

[0078] Step 412, determine whether the suspension board is in a shutdown state, if so, jump to step 402 to open the air inlet and turn on the annular light strip, if not, execute step 413.

[0079] Here, if the air conditioner's suspension board is not turned on, it is necessary to jump to the aforementioned step 402, the suspension board rises steadily under the action of the magnetic force, and the annular light strip cooperates with the rising action of the suspension board, and the brightness gradually increases from dark to brightest. In addition, the indoor unit MCU determines that the lighting function has been started based on the remote control command, and is not affected by the ambient light intensity, and controls the annular light strip to display at the maximum brightness, that is, executing step 413.

[0080] Step 413, maintaining maximum brightness display.

[0081] Here, the indoor unit MCU drives the power supply switching circuit to supply power to the annular light strip at a rated power supply opening.

[0082] Step 414, determine whether the air conditioner is turned off, if not, return to step 413, if so, execute step 410.

[0083] It can be understood that the air conditioner of this application embodiment introduces a suspension board based on magnetic levitation control at the air inlet of the air conditioner to solve the dust accumulation problem of the air conditioner evaporator. In addition, a ring-shaped light strip is embedded in the air inlet. Through the principle of light reflection, the suspension board design can be simpler and lower in cost, while achieving compatibility between the operating status display and auxiliary lighting functions of the air conditioner.

[0084] In an exemplary embodiment, the processor of the air conditioner can be implemented by one or more application specific integrated circuits (ASIC), DSP, programmable logic device (PLD), complex programmable logic device (CPLD), field programmable gate array (FPGA), general processor, controller, microcontroller (MCU), microprocessor, or other electronic components to execute the aforementioned method.

[0085] It should be noted that: "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0086] In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0087] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
