本申请要求2019年03月26日申请的,申请号为201910233484.7,名称为“空调器清洁装置、清洁方法及空调器”的中国专利申请的优先权,在此将其全文引入作为参考。This application claims the priority of the Chinese patent application filed on March 26, 2019, with the application number 201910233484.7, titled "Air Conditioner Cleaning Device, Cleaning Method, and Air Conditioner", which is hereby incorporated by reference in its entirety.
本申请属于空调器清洁上技术领域,具体涉及一种空调器清洁装置、清洁方法及空调器。This application belongs to the technical field of air conditioner cleaning, and specifically relates to an air conditioner cleaning device, cleaning method, and air conditioner.
空调在长时间的使用过程中,会有大量的粉尘污染物积聚,导致空调换热器等部件的换热性能下降,甚至加剧腐蚀老化,造成部件的永久性损坏。家用空调器中,换热系统长期运行后积聚的污染物会滋生各种微生物,散发异味,甚至有害成分,严重影响身心健康。During the long-term use of the air conditioner, a large amount of dust and pollutants will accumulate, causing the heat exchange performance of the air conditioner heat exchanger and other components to decline, and even aggravating corrosion and aging, causing permanent damage to the components. In household air conditioners, pollutants accumulated after long-term operation of the heat exchange system can breed various microorganisms, emit peculiar smells, and even harmful ingredients, which seriously affect physical and mental health.
现有的空调清洁方法,就是通过凝霜-化霜来实现空调的清洁,但是凝霜过程主要是通过对室内空气中的水汽凝结来完成,当空调运行在干燥环境中,空气中水分较少,不能满足凝霜的水量需求,造成凝霜速度慢,空调的清洁功能受到限制。The existing air conditioner cleaning method is to achieve the cleaning of the air conditioner by condensation-defrosting, but the condensation process is mainly completed by condensing the water vapor in the indoor air. When the air conditioner is running in a dry environment, there is less moisture in the air. , Can not meet the water demand for condensation, resulting in slow condensation speed, and the cleaning function of the air conditioner is restricted.
现有的空调室内机清洁时,结霜过程中,空调运行制冷模式,室内换热器吸热,空气中的水分冷凝结霜在室内换热器表面,此过程中,供冷凝结霜的空气直接取自空调本身的循环气流,循环风为室内循环风,但在冬季时,室内空气温度较室外高,高温风直接吹入,会降低结霜的速率,甚至将室内换热器表面的霜冰吹化脱落。化霜过程中,空调切换至制热模式,室内换热器散热,融化其表面的霜冰,但在夏季时,室内空气温度较室外低,低温风吹入,会降低化霜的速率,甚至将霜冰再次冻结。When the existing air conditioner indoor unit is cleaned, during the frosting process, the air conditioner operates in the cooling mode, and the indoor heat exchanger absorbs heat. The moisture in the air condenses and frosts on the surface of the indoor heat exchanger. During this process, the frosted air is condensed. The circulating air is directly taken from the air conditioner itself. The circulating air is the indoor circulating air. However, in winter, the indoor air temperature is higher than that of the outdoor. The direct blowing of high-temperature wind will reduce the rate of frosting and even reduce the frost on the surface of the indoor heat exchanger. The ice melted and fell off. During the defrosting process, the air conditioner switches to heating mode, and the indoor heat exchanger dissipates heat and melts the frost on its surface. However, in summer, the indoor air temperature is lower than that of the outdoors, and low temperature wind blowing in will reduce the defrosting rate, even Freeze the frost again.
因此,现有技术的空调器清洁装置存在清洁效率低的问题。Therefore, the prior art air conditioner cleaning device has a problem of low cleaning efficiency.

The air conditioner cleaning device is used for self-cleaning of the indoor heat exchanger 2.
新风机1设有新风通道4和出风通道5。新风通道4用于新风机1进风,出风通道5用于新风机1向室内换热器2送风。新风机1至少具有如下工作模式:空气经新风通道4进入新风机1后,再流经出风通道5输送至室内换热器2,空气经室内换热器2后又可以进去室内。The fresh air blower 1 is provided with a fresh air passage 4 and an air outlet passage 5. The fresh air passage 4 is used for the fresh air blower 1 to enter air, and the air outlet passage 5 is used for the fresh air blower 1 to send air to the indoor heat exchanger 2. The fresh air blower 1 has at least the following working modes: air enters the fresh air blower 1 through the fresh air passage 4, and then flows through the air outlet passage 5 to be transported to the indoor heat exchanger 2, and the air can enter the room after passing through the indoor heat exchanger 2.
新风机作为空气调节领域的新兴设备,常被独立于空调器用于空气的净化,能够使室内空气产生循环,最大程度化的进行室内空气置换,弥补了普通空调器无法向室内引入新鲜空气的缺陷。本实施例的新风机1将空气引入新风通道4,然后由出风通道5吹至室内换热器2。空调器还可包括接水盘10,接水盘10用于收集存储空调器的换热器正常工作中产生的冷凝水。出风通道5可贯穿接水盘10向室内换热器2送风。出风通道5的边缘 设置防漏结构,防止接水盘10内的冷凝水漏至新风机1内。As a new equipment in the field of air conditioning, fresh air fans are often used for air purification independent of air conditioners. They can circulate indoor air, maximize indoor air replacement, and make up for the inability of ordinary air conditioners to introduce fresh air into the room. . The fresh air blower 1 of this embodiment introduces air into the fresh air passage 4 and then blows the air to the indoor heat exchanger 2 from the air outlet passage 5.

The fresh air passage 4 is the air inlet of the fresh air blower 1, and the outdoor fresh air duct 6 and the first indoor return air duct 7 are the two air introduction directions.
室内换热器2的结霜除受空气湿度的影响外,还会受空气温度的影响,空气温度高不利于结霜,甚至高温空气会迟滞结霜过程,将换热器表面的霜层吹化、吹落。反之,空气温度低,不利于化霜。因此,本实施例充分考虑环境温度的适宜性,新风机1设有室内和室外两个引风口,可以根据室内外环境温度以及空气湿度,决定从哪一侧引风。The frosting of indoor heat exchanger 2 is not only affected by air humidity, but also by air temperature. High air temperature is not conducive to frosting, and even high-temperature air will delay the frosting process and blow the frost layer on the surface of the heat exchanger. Change, blow off. On the contrary, low air temperature is not conducive to defrosting. Therefore, in this embodiment, the suitability of the ambient temperature is fully considered. The fresh air blower 1 is provided with two indoor and outdoor air inlets, and it is possible to determine which side to draw air from according to the indoor and outdoor ambient temperature and air humidity.

The moisture in the air blown to the indoor heat exchanger 2 increases, and the surface condensation of the indoor heat exchanger 2 increases, which can accelerate the indoor Frosting of heat exchanger 2. The humidifying component 3 includes a humidifying device 9 and a water storage tank 8. The humidifying device 9 is installed in the fresh air passage 4. The humidifying device 9 includes any one or more of a humidifying membrane, a permeable membrane, and an atomizer. The humidifying device 9 is used to increase the humidity of the air flowing through the fresh air passage 4, and the water storage tank 8 is used to provide a water source to the humidifying device 9. The water storage tank 8 can be made into two water supply modes: internal circulation water supply and external injection water supply.
内循环供水模式借助换热器滴落的冷凝水。请一并参阅图5,在空调器内,室内换热器2的下方设置接水盘10,出风通道5贯穿接水盘10向室内换热器2送风。The internal circulation water supply mode relies on the condensate dripping from the heat exchanger.
