Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, in particular to an air conditioner. BACKGROUND

[0002] After the mobile air conditioner runs in the refrigeration or dehumidification mode for a period of time, a large amount of condensate water will accumulate at the bottom of the host, so a water level sensor is usually provided to remind the user to drain water in time and avoid the continuous increase of condensate water leading to overflow. However, when the external humidity is high, condensate water will continue to be generated at a high speed, so the user will need to discharge condensate water multiple times accordingly, and frequent operation seriously affects the user's experience. SUMMARY

[0003] Therefore, it is necessary to provide an air conditioner to solve the problem that the user needs to frequently drain water when the condensate water generation speed of some mobile air conditioners in the prior art is high, which affects the user's experience.

[0004] An air conditioner comprises a host, a bottom disc formed at the bottom of the host, a water collecting groove provided on the bottom disc and used for collecting condensate water, a water level detection assembly comprising a first water level sensor and a second water level sensor, the first water level sensor and the second water level sensor being arranged in the water collecting groove, a second sensing water level of the second water level sensor being higher than a first sensing water level of the first water level sensor, and a control device in communication connection with the first water level sensor and the second water level sensor, respectively, the first water level sensor generating a first working signal when the water level of the condensate water reaches the first sensing water level, the control device controlling the air conditioner to reduce the water level rising speed of the condensate water according to the first working signal, the second water level sensor generating a second working signal when the water level of the condensate water reaches the second sensing water level, and the control device controlling the air conditioner to stop generating condensate water according to the second working signal.

[0005] This application provides an air conditioner with a first water level sensor and a second water level sensor in the bottom water collection tank for monitoring the condensate water level. As the condensate water level rises to the first sensing level, the first water level sensor sends a first operating signal to a control device. The control device then instructs the air conditioner to adjust its operating mode, reducing the rate of rise of the condensate water level or even lowering the water level by decreasing cooling efficiency or consuming more condensate water. When the condensate water level continues to rise to the second sensing level, the second water level sensor sends a second operating signal to the control device, stopping the air conditioner from cooling to prevent further condensate generation and the risk of overflow. This device, through the cooperation of the first and second water level sensors, can extend the user's drainage execution time, reduce the frequency of drainage operations, and avoid frequent shutdowns of the air conditioner, thereby improving the reliability and stability of the device and enhancing the user experience.

[0006] In one embodiment, the system further includes a refrigeration system and a fan assembly, at least a portion of which are disposed within the main unit. The refrigeration system comprises a compressor, a condenser, a throttling device, and an evaporator, connected sequentially to form a refrigerant circuit. The water collection tank is used to collect condensate generated by the evaporator. The fan assembly is used to dissipate heat generated on the surfaces of the compressor and the condenser using air. The refrigeration system and the fan assembly are respectively communicatively connected to the control device. The control device will, based on operating signals sent by a first water level sensor and a second water level sensor, drive the refrigeration system and / or the fan assembly to adjust their operating modes to reduce the rate of condensate level rise, extend the user's drainage execution time, and reduce the frequency of drainage operations.

[0007] In one embodiment, the control device is configured to reduce the power consumption of the refrigeration system and / or the fan assembly according to the first operating signal. By employing the above configuration, when the condensate level reaches the first sensing level, the power consumption of the refrigeration system can be reduced, thereby decreasing the refrigeration efficiency and directly slowing down condensate formation. Alternatively, the power of the fan assembly can be reduced to decrease the airflow, thereby reducing the amount of external water vapor entering the air conditioner and liquefying in contact with the evaporator to form condensate. Furthermore, by reducing the airflow, the heat exchange efficiency of the condenser can be reduced to a certain extent. By reducing the refrigeration efficiency of the refrigeration system, the formation of condensate is reduced, and the rate of condensate level rise is slowed.

[0008] In one embodiment, the control device is configured to control the compressor to stop operating based on the second operating signal. When the condensate level reaches the second sensing level, the compressor stops cooling to prevent the condensate from continuing to rise and causing the risk of overflow, and to allow the user time to manually drain the condensate.

[0009] In one of the embodiments, the control device is configured to control the refrigeration system and / or the fan assembly to work at a first power according to the first working signal, the water level detection assembly further comprises a third water level sensor, a third sensing water level of the third water level sensor is between the first sensing water level and the second sensing water level, the control device is in communication connection with the third water level sensor, when the water level of the condensed water reaches the third sensing water level, the third water level sensor generates a third working signal, the control device is configured to control the refrigeration system and / or the fan assembly to work at a second power according to the third working signal, the second power is less than the first power. By setting the third water level sensor to cooperate with the first water level sensor and the second water level sensor to monitor the water level of the condensed water, the use power of the refrigeration system and / or the fan assembly can be better matched with the rising of the water level of the condensed water to achieve more accurate control.

[0010] In one of the embodiments, the number of the third water level sensors is multiple, the multiple third water level sensors are distributed along the height direction, and the second power corresponding to the multiple third water level sensors gradually decreases with the increase of the height of the third water level sensors. By adopting the above structure, as the water level of the condensed water rises, the use power of the refrigeration system and / or the fan assembly can be gradually reduced, so that the refrigeration effect will change slowly and gradually, avoiding the inconvenience of the user to the sudden change of the refrigeration effect of the air conditioner.

[0011] In one of the embodiments, a water removal assembly is further included, the water removal assembly comprises a water beating motor and a water beating impeller, the water beating motor and the water beating impeller are arranged on the bottom plate, the water beating impeller is partially located in the water collecting tank, the control device is in communication connection with the water beating motor, an output shaft of the water beating motor is in driving connection with the water beating impeller, and the water beating impeller is configured to rotate to beat the condensed water in the water collecting tank under the driving of the water beating motor. By adopting the above structure, the water beating motor can be used to drive the water beating impeller to beat the condensed water in the water collecting tank to contact with the high-temperature air in the air conditioner to exchange heat, so that the condensed water can be evaporated and consumed, thereby reducing the rising speed of the water level of the condensed water, and even reducing the water level.

[0012] In one of the embodiments, the control device is configured to control the water beating motor to start or accelerate according to the first working signal. Specifically, when the water level of the condensed water is lower than the first sensing water level, the water beating motor is stopped or operates at a lower speed, and when the water level of the condensed water reaches the first sensing water level, the water beating motor is started or accelerated to drive the water beating impeller to speed up the evaporation of the condensed water. By adopting the above structure, the operation of the water removal assembly can be accurately controlled, which is beneficial to save electric energy.

[0013] In one of the embodiments, the water spraying impeller is arranged at one side of the water collecting tank close to the condenser, and the water spraying impeller is configured to rotate under the driving of the water spraying motor to spray the condensing water in the water collecting tank to the condenser. By using the above structure, the condensing water in the water collecting tank is splashed to the high-temperature condenser under the beating of the water spraying impeller, so that on the one hand, the evaporation of the condensing water can be accelerated, and on the other hand, the condensing water exchanges heat with the condenser, so that the heat exchange efficiency of the condenser can be further improved.

[0014] In one of the embodiments, the bottom plate includes a plate body and a partition assembly, the plate body is provided with the water collecting tank, the partition assembly is arranged in the water collecting tank, the partition assembly divides the water collecting tank into a first water collecting tank and a second water collecting tank, the first water collecting tank and the second water collecting tank are communicated, the water level detection assembly is located in the first water collecting tank, and the water spraying impeller is located in the second water collecting tank. By using the above structure, the water level detection assembly and the water spraying impeller can be separated by the partition assembly, so that the influence of the splashing of the condensing water or the liquid surface fluctuation caused by the rotation of the water spraying impeller on the water level detection assembly can be reduced, and the detection result of the water level detection assembly can be ensured to be accurate and reliable.

[0015] In one of the embodiments, the partition assembly includes at least two partition plates, the at least two partition plates are oppositely arranged, the at least two partition plates cooperatively form a liquid passing channel, and the first water collecting tank and the second water collecting tank are communicated through the liquid passing channel. By forming the liquid passing channel to communicate the first water collecting tank and the second water collecting tank, the first water collecting tank and the second water collecting tank can be mutually communicated, and the liquid passing channel can provide a certain buffering effect, so that the liquid level fluctuation in the first water collecting tank caused by the liquid surge in the second water collecting tank when the water spraying impeller rotates can be avoided to influence the detection result of the water level detection assembly.

[0016] In one of the embodiments, the at least two partition plates are respectively provided with through holes, the through holes are used to communicate the liquid passing channel and the first water collecting tank and / or the second water collecting tank, and the through holes of the adjacent two partition plates are arranged in a staggered manner. By using the above structure, the flow path of the water flow between the first water collecting tank and the second water collecting tank can be prolonged, and the flow speed of the water flow can be reduced, so that the influence of the liquid surface fluctuation in the first water collecting tank on the liquid surface in the second water collecting tank caused by the rotation of the water spraying impeller can be further reduced, and the detection result of the water level detection assembly can be ensured to be accurate and reliable.

[0017] In one of the embodiments, the bottom wall of the first water collecting tank is recessed to form a first mounting groove, and the first water level sensor and the second water level sensor are arranged in the first mounting groove.

[0018] In one of the embodiments, the bottom wall of the second water diversion groove is recessed to form a second mounting groove, and the water beating impeller is arranged in the second mounting groove. By forming the second mounting groove, the space utilization of the bottom plate is improved, and the positioning and installation of the water beating impeller are facilitated, thereby facilitating the water beating impeller to beat the low-level condensed water.

[0019] In one of the embodiments, the bottom wall of the second water diversion groove is downwardly inclined towards the water beating impeller. In this way, the condensed water can be better gathered to the water beating impeller, so that the water beating impeller can better beat the low-level condensed water to promote evaporation and consumption.

[0020] In one of the embodiments, the warning device is further arranged, and the warning device is in communication connection with the control device. The control device is configured to control the warning device to issue a warning reminder according to the first working signal and / or the second working signal. Specifically, the warning device can be set to different levels of warning reminder signals. When the first water level sensor detects that the condensed water level reaches the first sensing water level, a first-level alarm is issued to prompt the user that there is more water in the air conditioner and attention is needed. When the second water level sensor detects that the condensed water level reaches a more dangerous second sensing water level, a second-level alarm is issued to remind the user to immediately perform drainage treatment, thereby effectively preventing water leakage of the air conditioner. In addition, the user can also know the working condition of the water level sensor according to the warning reminder sent by the warning device. Specifically, when one water level sensor fails, the other water level sensor can still work normally to continue to monitor the water level, which helps the user to find problems and repair, thereby reducing the risk of water leakage of the air conditioner caused by the failure of the water level sensor.

[0021] In one of the embodiments, the drainage valve is further arranged, and the bottom plate is provided with a drainage port communicating with the outside and the water collecting groove. The drainage valve is used to open or close the drainage port. By using the above structure, when the user receives the second-level alarm signal issued by the warning device, the drainage valve can be operated to open the drainage port of the bottom plate, so that the high-level condensed water accumulated in the water collecting groove can be discharged in time to avoid water leakage caused by overflow.

[0036] The application provides an air conditioner, a first water level sensor 21 and a second water level sensor 22 are arranged in a bottom water collecting tank 101 to monitor the water level of condensed water, as the water level of the condensed water rises to a first sensing water level, the first water level sensor 21 will send a first working signal to a control device, the control device will drive the air conditioner to adjust the operation mode, and the rising speed of the water level of the condensed water is reduced or even the water level is lowered by reducing the refrigeration efficiency or consuming the condensed water, and when the water level of the condensed water continuously rises to a second sensing water level, the second water level sensor 22 will send a second working signal to the control device, and the air conditioner is controlled to stop refrigeration to avoid the risk of continuous generation of condensed water overflow.

[0038] In addition to the features of the above embodiments, the present embodiment is further limited in that the control device is configured to control the refrigeration system and / or the fan assembly to reduce the use power according to the first working signal. By adopting the above arrangement, when the condensate water level reaches the first sensing water level, the generation of condensate water can be slowed down directly by reducing the use power of the refrigeration system to reduce the refrigeration efficiency of the refrigeration system, or by reducing the power of the fan assembly to reduce the wind speed, so that the external water vapor entering the air conditioner and contacting the evaporator to be liquefied to generate condensate water can be reduced, and by reducing the air volume, the heat exchange efficiency of the condenser can be reduced to some extent.

When the condensate water level reaches the second sensing water level, the compressor stops refrigeration to avoid the risk of continuous rising of the condensate water and to leave reaction time for the user to manually drain water.

[0040] In addition to the features of the above embodiments, the present embodiment is further limited in that the control device is configured to control the refrigeration system and / or the fan assembly to work at a first power according to the first working signal, and the water level detection assembly 2 further comprises a third water level sensor, the third sensing water level of the third water level sensor is located between the first sensing water level and the second sensing water level, and the control device is in communication connection with the third water level sensor.

By adopting the above structure, as the condensate water level rises, the use power of the refrigeration system and / or the fan assembly can be gradually reduced, so that the refrigeration effect will change slowly and gradually, avoiding the inconvenience of the user to the sudden change of the refrigeration effect of the air conditioner.

[0042] As Figures 1 to 4As shown, in addition to the features of the above embodiments, this embodiment further includes a water removal component 3. The water removal component 3 includes a water pumping motor 31 and a water pumping impeller 32. The water pumping motor 31 and the water pumping impeller 32 are mounted on the chassis 1. The water pumping impeller 32 is partially located in the water collection tank 101. The control device is communicatively connected to the water pumping motor 31. The output shaft of the water pumping motor 31 is driven by the water pumping impeller 32. The water pumping impeller 32 is configured to rotate under the drive of the water pumping motor 31 to strike the condensate in the water collection tank 101.

By adopting the above settings, the operation of the water removal component 3 can be precisely controlled, which is beneficial to saving energy.

[0044] In addition to the features of the above embodiments, this embodiment further specifies that: the water-discharging impeller 32 is disposed on the side of the water collection tank 101 near the condenser, and the water-discharging impeller 32 is configured to rotate under the drive of the water-discharging motor 31 to spray the condensate in the water collection tank 101 onto the condenser. By adopting the above structure, the condensate in the water collection tank 101 splashes onto the high-temperature condenser under the impact of the water-discharging impeller 32, thereby accelerating the evaporation of the condensate and exchanging heat between the condensate and the condenser, further improving the heat exchange efficiency of the condenser.

[0047] As Figure 2 shown, in addition to the features of the above embodiments, the present embodiment is further limited in that: the at least two partition plates 121 are respectively provided with through holes 103, the through holes 103 are used to communicate the liquid passing channel 102 with the first water distribution groove 1011 and / or the second water distribution groove 1012, and the through holes 103 of adjacent two partition plates 121 are arranged in a staggered manner. By adopting the above structure, the flow path of the water flow between the first water distribution groove 1011 and the second water distribution groove 1012 can be extended, and the water flow speed can be reduced, so that the influence of the rotation of the water beating impeller 32 on the liquid surface fluctuation of the first water distribution groove 1011 can be further reduced, and the detection result of the water level detection assembly 2 can be ensured to be accurate and reliable.

By forming the first mounting groove 104, the positioning and installation of the first water level sensor 21 and the second water level sensor 22 can be facilitated, and the space utilization of the bottom plate 1 is improved.

[0049] As Figure 4 shown, in addition to the features of the above embodiments, the present embodiment is further limited in that: the bottom wall of the second water distribution groove 1012 is recessed to form a second mounting groove 105, and the water beating impeller 32 is arranged in the second mounting groove 105. By forming the second mounting groove 105, the space utilization of the bottom plate 1 is improved, and the positioning and installation of the water beating impeller 32 are facilitated, which provides convenience for the water beating impeller 32 to beat the low water level condensate water.

[0050] As Figure 4As shown, in addition to the features of the above embodiments, the present embodiment is further defined as: the bottom wall of the second water diversion groove 1012 is inclined downwardly towards the direction close to the water beating impeller 32.

When the second water level sensor 22 detects that the condensed water level reaches a more dangerous second sensing water level, a second-level alarm is issued to remind the user to immediately drain the water, thereby effectively preventing the air conditioner from leaking. In addition, the user can also know the working condition of the water level sensor according to the warning reminder sent by the warning device. Specifically, when one water level sensor fails, the other water level sensor can still work normally to continue monitoring the water level, which gives the user time to find the problem and repair, and reduces the risk of air conditioner water leakage caused by water level sensor failure.
