Description

Air Conditioner

Technical Field

The utility model relates to the technical field of air conditioners, in particular to an air conditioner.

Background technique

Mobile air conditioners are different from conventional split air conditioners. The internal and external units are integrated into one unit. The two units are arranged in the same space, and the structural layout is relatively dense. When the evaporator produces condensed water, it is usually necessary to use a water pumping device to discharge the condensed water to the location of the condenser, so as to achieve water cooling and discharge the water vapor formed by the condensed water.

Window air conditioners are different from common split air conditioners. The indoor and outdoor units are integrated designs. The two devices are arranged in the same space and the structural layout is relatively dense. When the evaporator produces condensed water, it is usually necessary to discharge the condensed water to the location of the condenser to achieve water cooling while discharging the water vapor formed by the condensed water.

However, when a mobile air conditioner or a window air conditioner needs to have a self-cleaning function, there will be a hidden danger of sewage discharge. When the air conditioner is self-cleaning, the dirt produced by cleaning is also discharged to the condenser along with the condensed water. This part of the dirt cannot be discharged by evaporation, but will adhere to the surface of the condenser, which will cause the safety hazard of poor heat dissipation of the condenser and greatly reduce the energy efficiency of the system. On the other hand, if a water pump or other device is used to discharge the condensed water to the condenser, the dirt in the condensed water will easily block the inside of the water pump.

In this embodiment, the evaporator will form condensed water on the surface; the water receiving pan is located below the evaporator to receive the condensed water gathered and dripping from the evaporator; the temperature of the condenser 8 will increase during operation; the condenser 8 is cooled by the condensed water in the water storage pan 4, so as to improve the working effect of the condenser 8 and extend the working time of the condenser 8; the water storage pan 4 is connected with the water receiving pan, so that the water in the water receiving pan can flow into the water storage pan 4, reducing the amount of condensed water in the water receiving pan; a drain outlet 2 is provided in the water storage pan 4, and a control valve 1 is provided at the drain outlet 2, so as to control the valve 1 to control the conduction and cutoff of the drain outlet 2.

After the evaporator is cleaned with clean condensed water for a period of time, the control valve 1 is opened to allow the drain port 2 to be connected, so that the condensed water with dirt is discharged; or after the condenser 8 is cleaned with clean condensed water for a period of time, the control valve 1 is opened to allow the drain port 2 to be connected, so that the condensed water with dirt is discharged; or after the evaporator and condenser 8 are cleaned with clean condensed water for a period of time at the same time, the control valve 1 is opened to allow the drain port 2 to be connected, so that the condensed water with dirt is discharged.

Through the arrangement of this embodiment, when the self-cleaning function is not executed, the clean condensed water in the water storage pan 8 is transported to the condenser or evaporator; when the self-cleaning function is executed, the control valve 1 is opened to discharge the condensed water with dirt in the water storage pan 4 from the drain outlet 2, thereby reducing or avoiding the adhesion of dirt to the surface of the condenser 8, thereby achieving the effect of improving the energy efficiency of the clean window air conditioner system and reducing safety hazards.

In some embodiments of the present utility model, as shown in Figure 1, the air conditioner also includes a water pumping device 7 and a water level detection device 3, the water pumping device 7 pumps the water in the water storage pan 4 onto the condenser 8; the water level detection device 3 is used to detect the water level in the water storage pan 4, and the water level detection device 3 is connected to the control valve 1, so that when the water pumping device 7 is working and the water level of the water storage pan 4 monitored by the water level detection device 3 reaches a preset maximum water pumping level, the control valve 1 is controlled to open the drain port 2 and the water pumping device 7 is controlled to be closed; or, when the water level of the water storage pan 4 monitored by the water level detection device 3 reaches a preset maximum static water level, the control valve 1 is controlled to open the drain port 2.

In this embodiment, the water pumping device 7 is arranged in the water storage pan 4 or above the water storage pan 4 and close to the condenser 8, so as to pump the clean condensed water in the water storage pan 4 onto the condenser 8, thereby cooling the condenser 8 and maintaining the working performance of the condenser 8.

The water level detection device 3 can be a float switch 14, a water level detection sensor, a water level detector, or the like, which can control the opening of the valve 1.

The water level detection device 3 is disposed in the water storage pan 4 for detecting the water level in the water storage pan 4 , and is connected to the control valve 1 to control the opening and closing of the control valve 1 .

The preset maximum water level is the maximum water level when the condensed water in the water storage pan 4 fluctuates. At this time, the control valve 1 is opened, the water pumping device 7 is closed, and the condensed water in the water storage pan 4 is discharged from the drain port 2.

The preset highest static water level is the highest water level when the condensed water in the water storage pan 4 is in a static state and the pumping device 7 is not running. At this time, the control valve 1 will be opened to allow the condensed water to be discharged from the drain port 2.

Through the setting method of this embodiment, when the water level detection device 3 of the utility model detects that the water level in the water storage pan 4 reaches a preset maximum water filling level or a preset maximum static water level, it opens the control valve 1 to allow the condensed water in the water storage pan 4 to be discharged from the drain outlet 2, thereby preventing the water level in the water storage pan 4 from exceeding the limit, causing the air conditioner to be full of water, causing the air conditioner to shut down, and thus affecting the user experience.

In some embodiments of the present invention, referring to FIG. 1 and FIG. 2 , the water level detection device 3 is a float switch 14 . The float switch 14 includes a float 9 to generate a signal by detecting the position of the float 9 .

In this embodiment, the water level detection device 3 used in the utility model is a float switch 14. The float 9 in the float switch 14 can float on the water surface to detect the height of the water level. The float switch 14 can generate an electrical signal from the detected position of the float 9, and then send it to the control valve 1 to control the valve 1 to open or close it.

For example, when the float 9 is at a preset low position, the float switch 14 generates a low-level signal and sends it to the control valve 1, thereby controlling the valve 1 to close according to the low-level signal; when the float 9 is at a preset high position, the float switch 14 generates a high-level signal and sends it to the control valve 1, thereby controlling the valve 1 to open according to the high-level signal.

Alternatively, when the float 9 is at a preset low position, the float switch 14 generates a high-level signal and sends it to the control valve 1, thereby controlling the valve 1 to close according to the high-level signal; when the float 9 is at a preset high position, the float switch 14 generates a low-level signal and sends it to the control valve 1, thereby controlling the valve 1 to open according to the low-level signal.

Through the setting method of this embodiment, the utility model adopts a float switch 14 as the water level detection device 3, and detects the water level in the water storage tray 4 through the float 9. The float switch 14 generates a signal according to the detection result and sends it to the control valve 1, thereby opening or closing the control valve 1 to achieve the conduction or cutoff of the drain outlet 2.

In some embodiments of the present invention, as shown in FIG. 1 , the water storage tray 4 includes a bottom tray 6 and a peripheral wall 5 located at the edge of the bottom tray 6 ; the drain port 2 is disposed on the peripheral wall 5 .

In this embodiment, the bottom plate 6 and the peripheral wall 5 at the edge of the bottom plate are tightly combined to form a water storage space capable of storing water.

The drain port 2 is arranged at the lowest position of the peripheral wall 5 of the water storage pan 4, so that when the drain port 2 is opened, all the condensed water with dirt in the water storage pan 4 can be discharged, so that no water will accumulate and no dirt will settle in the water storage pan 4.

Alternatively, the peripheral wall 5 of the water storage pan 4 where the drain port 2 is located is at the lowest position of the water storage pan 4, so that when the drain port 2 is connected, all the condensed water with dirt in the water storage pan 4 can be discharged, so that no water will accumulate and no dirt will settle in the water storage pan 4.

Through the arrangement of this embodiment, the utility model adopts a structure in which the drain port 2 is arranged at the lowest position on the peripheral wall 6 of the water storage tray 4, so that when the drain port 2 is opened, all the condensed water with dirt in the water storage tray 4 can be discharged to achieve a cleaning effect.

In some embodiments of the present invention, the air conditioner is a mobile air conditioner or a window air conditioner.

In this embodiment, the air conditioner in the utility model can be a mobile air conditioner or a window air conditioner.

The internal and external units of a mobile air conditioner or a window air conditioner are integrated into one, arranged in the same space, and have a relatively dense structure. The arrangement method of the present invention can be used.

The air conditioner of the utility model can be a mobile air conditioner or a window air conditioner, which improves the versatility of the utility model.

In some embodiments of the utility model, referring to Figure 1, the air conditioner also includes a shell, an air duct and a drain pipe 10; the evaporator, the water receiving tray, the condenser 8 and the water storage tray 4 are all arranged in the shell, and the shell has a hot air outlet for the air flow flowing out through the condenser; the air duct is connected to the hot air outlet; the drain pipe 10 is connected to the drain outlet.

In this embodiment, the shell of the air conditioner is used to shield the evaporator, condenser 8, water receiving tray and water storage tray 4 to prevent debris outside the air conditioner from entering the air conditioner and affecting the working performance of the evaporator and condenser 8.

During the operation of the air conditioner, the airflow direction of the hot air outlet on the air conditioner housing is from inside the housing to outside the housing, preventing external debris from entering the air conditioner. The air duct is connected to the hot air outlet, directly directing the airflow in the air conditioner to the position set by the user; the drain outlet 2 of the air conditioner drains the condensed water in the water storage pan 4 to the position set by the user through the connected drain pipe 10.

After the water-pumping device 7 pumps the condensed water in the water storage pan 4 onto the condenser 8, the condensed water will evaporate to form water vapor while cooling the condenser 8; the airflow passing through the condenser 8 will blow the water vapor out of the hot air outlet on the air conditioner shell, and then be discharged from the air conditioner through the air duct, reducing the amount of condensed water in the water storage pan 4.

Through the setting method of this embodiment, the shell of the air conditioner in the utility model can shield the evaporator, condenser 8, water receiving tray and water storage tray 4, ensure the working effect of the evaporator, condenser 8, water receiving tray and water storage tray 4, and prevent debris outside the air conditioner from entering and affecting their performance; the hot air outlet and air duct set on the air conditioner can blow the water vapor generated on the condenser 8 out of the air conditioner through the air flow in time, reduce the amount of condensed water in the water storage tray 4, and avoid causing the water level in the water storage tray 4 to exceed the limit, causing the air conditioner to malfunction or even shut down; the drain pipe 10 is connected to the drain outlet 2, so that the condensed water flowing out of the drain outlet 2 can reach the position where the user places the outlet of the drain pipe 10, avoiding direct discharge from the drain outlet 2, forming a large amount of accumulated water at the position where the air conditioner is placed, affecting the user's experience.

In some embodiments of the present invention, referring to FIG. 1 , the water pumping device 7 includes a water pumping wheel, and the lowest water-touching position of the water pumping wheel is lower than the lowest water-touching position of the float 9 .

In this embodiment, the water pumping device 7 further includes a motor and a rotating shaft. The motor is connected to the rotating shaft, and a water pumping wheel is arranged on the rotating shaft. When the water pumping device 7 is running, the motor drives the water pumping wheel on the rotating shaft to rotate.

When the water pumping device 7 is running, the water pumping wheel will carry condensed water from the lowest water-touching position of the water pumping wheel. During the rotation, the water pumping wheel will pump the carried condensed water onto the condenser 8 to cool the condenser 8. At the same time, the condensed water that cools the condenser 8 is converted into water vapor and discharged through the air duct.

The lowest water-touching position of the water-pumping wheel is lower than the lowest water-touching position of the float 9 in the float switch 14, so that the control valve 1 is closed after the float 9 is at the lowest water-touching position, so that the water storage tray 4 can store the condensed water flowing out of the water receiving tray, and after the water level in the water storage tray 4 reaches the lowest water-touching position of the water-pumping wheel, the water-pumping device 7 is operated, and the water-pumping wheel pumps the condensed water in the water storage tray 4 onto the condenser 8, thereby cooling the condenser 8 and reducing the time of ineffective operation of the water-pumping device 7.

Alternatively, the lowest water-touching position of the water-pumping wheel is lower than the lowest water-touching position of the float 9 in the float switch 14, so that the control valve 1 is closed after the float 9 is at the lowest water-touching position, and the water-pumping device 7 is operated at the same time, so that the water storage tray 4 can store the condensed water in the water receiving tray, and after the water level in the water storage tray 4 reaches the lowest water-touching position of the water-pumping wheel, the water-pumping wheel pumps the condensed water in the water storage tray 4 onto the condenser 8 to cool the condenser 8.

Through the setting method of this embodiment, the utility model allows the lowest water-touching position of the water wheel to be lower than the lowest water-touching position of the float 9. After the control valve 1 is closed, the water-pumping device 7 can pump the condensed water in the water storage tray 4 onto the condenser 8 as soon as possible, thereby reducing the ineffective operation time of the water-pumping device 7.

In some embodiments of the present invention, referring to FIG. 1 , the water pumping device 7 includes water pumping wheels. There are at least two water pumping wheels, which are respectively disposed on both sides of the condenser 8 .

In this embodiment, for example, the water pumping device 7 is provided with two water pumping wheels, which are respectively provided on both sides of the condenser 8, so that when the water pumping device 7 is running, the two water pumping wheels can cool down both sides of the condenser 8 at the same time, so that the temperature on both sides of the condenser 8 is always maintained at the same standard.

For example, multiple water-pumping wheels are provided and symmetrically distributed on both sides of the condenser 8, so that when the water-pumping device 7 is running, multiple water-pumping wheels cool down both sides of the condenser 8 at the same time, thereby improving the cooling effect on the condenser 8, and quickly converting the condensed water in the water storage tray 4 into water vapor, and then discharging the water vapor through the air duct.

Through the setting method of this embodiment, the water pumping device 7 in the air conditioner of the utility model is provided with at least two water pumping wheels, and they are evenly arranged on both sides of the condenser 8, so as to cool down both sides of the condenser 8 at the same time, so that the temperatures on both sides of the condenser 8 are always maintained at the same standard, avoiding uneven heating of the condenser 8 and affecting the performance of the condenser 8.

In some embodiments of the present invention, referring to FIG. 1 and FIG. 2 , the float switch 14 includes two detection heads with different heights, and the detection heads are configured to contact with the float 9 to generate a signal.

In this embodiment, the detection head can be any sensing device that generates a signal by contacting the float 9, such as a touch sensor, a contact sensor, etc., which generates a low-level or high-level signal when the float 9 contacts the detection head.

The float switch 14 includes two detection heads of different heights, namely an upper detection head 11 and a lower detection head 12. The upper detection head 11 is located above the lower detection head 12, and the setting positions of the upper detection head 11 and the lower detection head 12 on the float switch 14 can be set according to actual needs.

The float switch 14 also includes a straight rod 13, on which a float 9 is sleeved, and the float 9 can move up and down on the straight rod 13 without friction; and an upper detection head 11 and a lower detection head 12 are provided on the straight rod 13, so that when the float 9 moves up and down with the water level, it contacts the upper detection head 11 or the lower detection head 12, and then the upper detection head 11 or the lower detection head 12 generates a low-level signal or a high-level signal.

For example, when the float 9 contacts the upper detection head 11, the upper detection head 11 generates a high-level signal, and sends the high-level signal to the control valve 1, thereby controlling the control valve 1 to open, allowing the condensed water with dirt in the water storage pan 4 to be discharged from the drain port 2; when the float 9 contacts the lower detection head 12, the lower detection head 12 generates a low-level signal, and sends the low-level signal to the control valve 1, thereby controlling the control valve 1 to close, allowing the water storage pan 4 to store condensed water.

Alternatively, when the float 9 contacts the upper detection head 11, the upper detection head 11 generates a low-level signal, and sends the low-level signal to the control valve 1, thereby controlling the control valve 1 to open, allowing the condensed water with dirt in the water storage pan 4 to be discharged from the drain port 2; when the float 9 contacts the lower detection head 12, the lower detection head 12 generates a high-level signal, and sends the high-level signal to the control valve 1, thereby controlling the control valve 1 to close, allowing the water storage pan 4 to store condensed water.

Through the arrangement of this embodiment, the float switch 14 in the air conditioner of the utility model is provided with two detection heads of different heights, namely, the upper detection head 11 and the lower detection head 12. When the upper detection head 11 contacts the float 9, a signal is generated and the control valve 1 is controlled to be opened according to the signal, so that the condensed water in the water storage pan 4 is discharged; when the lower detection head 12 contacts the float 9, a signal is generated and the control valve 1 is controlled to be closed according to the signal, so that the water storage pan 4 stores the condensed water flowing out of the water receiving pan. The opening or closing of the control valve 1 is controlled according to the contact between the float 9 and different detection heads, so that different treatments of the condensed water in the water storage pan 4 are achieved.

In some embodiments of the present invention, a first valve is provided at the outlet of the water receiving tray, so as to control the first valve to close when the water level of the water storage tray 4 reaches a preset maximum static water level.

In this embodiment, the water receiving tray and the water storage tray 4 are connected through a first valve. When the first valve is opened, condensed water in the water receiving tray flows into the water storage tray 4; when the first valve is closed, condensed water in the water receiving tray is prohibited from flowing into the water storage tray 4.

When the control valve 1 at the drain outlet 2 is closed, the first valve is in a normally open state, so that the condensed water in the water receiving tray flows to the water storage tray 4, and then the condensed water is pumped onto the condenser 8 through the water pumping device 7. The condensed water pumped onto the condenser 8 turns into water vapor and is discharged from the hot air outlet to the outside of the air conditioner.

When the control valve 1 at the drain port 2 is opened, the first valve is in a closed state, so that the condensed water with dirt in the water storage pan 4 can be quickly discharged from the drain port 4 .

When the water level of the water storage pan 4 reaches a preset maximum static water level, the control valve 1 is opened to connect the drain port 2 and the water storage pan 4 so that the condensed water in the water storage pan 4 can be discharged through the drain port 2 .

Through the arrangement of this embodiment, in the air conditioner of the utility model, the water receiving pan and the water storage pan 4 are connected and cut off by the first valve, so that when the first valve is opened, the condensed water in the water receiving pan flows to the water storage pan 4, the condenser 8 is cooled by water, and then the condensed water is converted into water vapor and discharged from the air duct; or when the first valve is closed, the condensed water with dirt in the water storage pan 4 is discharged from the drain port 2 as soon as possible to achieve a cleaning effect.

In some embodiments of the utility model, referring to FIG. 1 and FIG. 2, when the air conditioner is in a non-self-cleaning mode, the float switch 14 does not control the control valve 1 to open, and the water pumping device 7 starts running immediately after the compressor is started. When the compressor is turned off, the water pumping device 7 continues to run for a first preset time and then stops; or, after the float switch 14 controls the control valve 1 to open, the water pumping device 7 is directly shut down; or, when the air conditioner enters the self-cleaning mode, the water pumping device 7 is directly shut down.

When the float 9 in the float switch 14 contacts the upper detection head 11, the control valve 1 is opened; or, when the air conditioner is in the self-cleaning mode, the control valve 1 is opened.

When the float switch 14 contacts the lower detection head 12 or the air conditioner is in a non-self-cleaning mode, the control valve 1 is closed.

When the air conditioner is in non-self-cleaning mode, condensed water enters the water storage pan 4, and the pumping device 7 pumps water normally to cool the condenser 8, reducing the amount of condensed water stored in the water storage pan 4; when there is a lot of condensed water in the water storage pan 4, and it reaches the preset highest static water level or the preset highest dynamic water level, the condensed water will push the float 9 to a high position to trigger the upper detection head 11 of the float switch 14 and generate a signal. According to the signal, the pumping device 7 stops, controls the valve 1 to open, and directly drains the water. After draining, the float switch 14 contacts the lower detection head 12 and generates a corresponding signal. According to the signal, the valve 1 is controlled to close, and the pumping device 7 resumes normal operation.

When the air conditioner is in the self-cleaning mode, the water pumping device 7 is stopped, the control valve 1 is opened, and the generated condensed water and dirt are directly discharged, and no water accumulates in the water storage pan 4 and no dirt is precipitated.

Through the setting method of this embodiment, the air conditioner of the utility model can realize the drainage scheme of the self-cleaning mode of the mobile air conditioner or the window air conditioner. Through the cooperation of various devices, it can normally play the function of pumping water for cooling and improving the energy efficiency of the system. While preventing the hidden danger of excessive overflow of condensed water, it can also effectively avoid the hidden danger of siltation in self-cleaning sewage discharge.

At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
