Description

Air conditioner indoor unit heat exchanger cleaning system

technical field

The utility model relates to a cleaning system for an air conditioner heat exchanger, in particular to a split type air conditioner indoor unit heat exchanger cleaning system.

Background technique

The split air conditioner is a type of air conditioner that is widely used in homes. Although the general air-conditioning indoor unit has a filter to filter the air, some fine dust will still pass through the air filter and reach the surface of the heat exchanger, forming a layer of dirt on the surface of the heat exchanger. Continuing to increase the thickness of the dirt, the dirt will adversely affect the heat transfer effect of the heat exchanger, thereby reducing the use effect of the air conditioner and increasing the operating cost of the air conditioning system.

In the prior art, when cleaning the air conditioner, the filter screen is generally removed for cleaning, and this method is not suitable for cleaning the heat exchanger. Heat exchanger cleaning generally adopts two methods: chemical cleaning and high-pressure water jet cleaning. For a long time, the traditional cleaning process and treatment methods: such as mechanical scraping method, high-pressure water, chemical cleaning, such as pickling, etc., not only cannot effectively solve the problem thoroughly, but also the cleaning process is cumbersome, time-consuming and laborious.

In addition, when the air conditioner is working, the air conditioner always produces a large amount of condensed water. The greater the humidity of the air, the more condensed water produced. When the air conditioner is in cooling mode, the temperature of the coil in the indoor unit is lower than the temperature of the indoor air. When the air passes through the coil, the moisture in the air will condense rapidly due to the temperature drop, and become liquid and adhere to the coil, accumulating more It will flow into the sump at the lower part of the coil and finally flow out of the outdoor through the condensate pipe, resulting in waste of water.

Therefore, it is a problem worth studying to provide a device that can make full use of the condensed water generated during the operation of the air conditioner, and can clean the dust on the surface of the heat exchanger in a simple, convenient and practical way.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figure 1 and Figure 2, the heat exchanger cleaning system of the air conditioner indoor unit includes a water tank 3 arranged outside the air conditioner indoor unit, a flow diverter 8 connected to the water tank 3 through an upper water pipe, and the flow diverter 8 is connected to the branch pipe 9 of the flow diverter; The water collecting tank below the indoor unit of the air conditioner is connected with a filter water tank 1, and the filter water tank 1 is connected to the water tank 3 through the downpipe; the upper water pipe is provided with a motor water pump 7; the branch pipe 9 of the diverter is provided with a nozzle 10;

The upper right side of the water tank 3 is provided with a water injection pipe 6, the water tank 3 on the lower side of the water injection pipe 6 is provided with a drain pipe 4, and the drain pipe 4 is provided with a solenoid valve 5;

The nozzle 10 is oblique to the direction of the coil and forms an included angle of 45 degrees;

The flow divider 8 is connected with a plurality of flow divider branch pipes 9, and a plurality of nozzles 10 are distributed on each flow divider branch pipe 9;

The filter water tank 1 is provided with a three-stage filter screen 2;

The three-stage filter screen 2 is arranged sequentially from left to right in the direction of connecting the sump, and the bottom columns of the filter screen are lowered sequentially;

The water tank 3 is a transparent water tank;

The filter water tank 1 is connected to the end of the water collection tank, and the bottom of the water collection tank at the connection between the two is thicker than the conventional bottom, and is set in a conical groove shape, which is inserted and engaged with the filter water tank 1; the edge of the filter water tank 1 is conical Shaped like a slope, the surface of the slope is covered with a layer of silica gel.

The utility model adds a filter water tank 1 at the end of the water collection tank, thickens the bottom of the water collection tank and makes it into a tapered groove shape at the junction of the filter water tank and the water collection tank, so that the filter water tank can be inserted and occluded, as shown in the figure As shown in 3, the edge of the filter tank is made into a tapered slope. In order to avoid the leakage of condensed water, the slope is covered with a layer of silica gel. Silica gel is a kind of highly active adsorption material. When inserted, it is subjected to force and can effectively solve the connection The tightness of the place.

The filter water tank performs three-stage filtration on the condensed water. The bottom columns of the three filters are lowered in turn, and the dirt in the condensed water settles at the bottom of the tank. The filter screen can make the water flow filter more thoroughly until it flows into the water tank 3 for storage through the three filter screens. The filter water tank 1 is connected to the water tank 3 through the downpipe, and the water tank 3 is set up outside the machine. As shown in Figure 2, in order to facilitate users to observe the water level, the water tank is made into a transparent water tank. The upper part of the right side of the water tank is connected to the water injection pipe 6, and the water is injected to supplement when the water flow of the cleaning condensate pipe is insufficient; When there is too much, or the condensed water circulates many times and the water quality is not filtered and becomes turbid, or the user wants to discharge the water for other purposes, it can be controlled through the solenoid valve 5 on the drain pipe.

The motor water pump 7 pumps the water in the water tank 3 into the flow divider 8 above the water pump through the upper water pipe, and then flows into the three flow divider branch pipes 9 through the flow flow divider 8, and several nozzles 10 are distributed on each flow divider branch pipe 9, as shown in Figure 4 As shown, the direction of the nozzle 10 is inclined to the direction of the coil at an angle of 45 degrees, so that the washed water can flow into the sump better; the function of the nozzle 10 is to spray water to the coil, because the pressure of the water pump is very high. Large, when passing through the valve with a small opening degree, the impulsive force of the spray will wash the coil cleaner; the cleaned water flows back to the cold sump, is filtered and purified through the filter tank 1 at the end, and then flows into the water tank 3 again, completing a cycle . During the process, the dirt generated by the coil is collected into the filter water tank 1. Since the water in the water collection tank does not flow continuously when the air conditioner is running, it is necessary to pull out the filter water tank 1 for cleaning when the air conditioner stops running. The cleaning time interval can be freely controlled by the user. However, if the water in the transparent water tank is slightly turbid, it needs to be cleaned immediately.

The system is simple to operate, safe and reliable. When you need to clean the air conditioner, you only need to turn off the running air conditioner, make sure that the water in the water tank is enough for recycling, and if it is not enough, you can fill it through the water injection pipe. When the water volume is sufficient, the motor can be turned on to start the water pump, and the cleaning effect can be achieved in just ten minutes. After the cleaning is completed, the motor can be turned off. If the water in the water tank becomes slightly cloudy after repeated washing, it indicates that the filter tank needs to be cleaned. At this time, the water in the water tank should be drained through the drain pipe, and the filter tank should be drawn out for cleaning.

The above embodiments are only used to illustrate the technical solution of the utility model without limitation. Within the scope of knowledge of the ordinary skilled person, the technical solution of the utility model can be modified or equivalently replaced without departing from the purpose of the technical solution and scope, which should be included in the scope of the claims of the present utility model.
