The indoor unit of the air conditioner provided by the embodiment has a water washing function. The indoor unit of the air conditioner can be an indoor unit of a split air conditioner, such as a floor type air conditioner and a wall-mounted air conditioner, or an indoor unit of an integrated air conditioner. Such as window air conditioners, mobile air conditioners, etc.

As shown in fig. 1 to 4, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including: the casing 10, the water tank 20, the first detecting part, the second detecting part, and the third detecting part. The water tank 20 can be drawn in the casing 10 for holding water. By the cooperation of the first detecting member, the second detecting member, and the third detecting member, it is possible to detect not only the water level in the water tank 20 but also whether or not the water tank 20 is drawn out.

The casing 10 is provided with a containing cavity; the water tank 20 is arranged in the accommodating cavity and can slide along a first direction to be pulled out or pushed in, and a first detection component is arranged in the water tank 20; the second detecting component is arranged on the shell 10 and is adjacent to the water tank 20 and is correspondingly arranged with the first detecting component, and the second detecting component and the first detecting component are matched to detect the water level in the water tank 20; the third detecting member is provided to the water tank 20 and is disposed along the first direction with the second detecting member, and the third detecting member cooperates with the second detecting member to detect whether the water tank 20 is drawn out.

By adopting the air conditioner indoor unit provided by the embodiment of the disclosure, the water tank 20 is arranged in the shell 10, so that the air conditioner indoor unit has the functions of washing and purifying; through a second detection part, respectively with the water level condition in the first detection part cooperation detection water tank 20, with the cooperation of third detection part detection water tank 20 by the extraction, optimized overall structure, and can realize simultaneously detecting water level and the purpose that water tank 20 was taken out, reduced spare part's use, the cost is reduced.

The receiving chamber of the cabinet 10 is of a side opening structure, and the water tank 20 slides in a first direction to be drawn out of or pushed into the receiving chamber of the cabinet 10. The first direction may be transverse. I.e., the water tank 20 is drawn transversely to the cabinet 10.

The first detecting member is provided in the water tank 20 and is floatable with the water level in the water tank 20. The second detecting member is provided in the casing 10 adjacent to the water tank 20 and can cooperate with the first detecting member to detect the water level in the water tank 20. For example, the second detecting member can sense the first detecting member only when the water level is lower than the preset value, so as to trigger the second detecting member, and then the alarm prompts the user that the water tank 20 is lack of water.

The third detection part is arranged on the water tank 20 and is arranged along the first direction with the second detection part, and when the water tank 20 is pulled out, the third detection part moves along the first direction and approaches the second detection part to trigger the second detection part, so that an alarm prompts a user, and the water tank 20 is pulled out to prevent accidents.

In practical application, the alarm sound of the water shortage of the water tank 20 and the alarm sound of the water tank 20 extracted can be the same or different, and the user hearing recognition is facilitated under the condition of different alarm sounds. In addition, the alarm can be displayed by not only sound, but also display, regardless of whether the water tank 20 is out of water or the water tank 20 is pulled out. Illustratively, the alarm is given in the event of a water shortage of the water tank 20, the user knows, and the alarm sound is canceled to prevent influence on others. However, if the user forgets to add water, the user may still be prompted to add water to the water tank 20 by the display function when the alarm sound is canceled.

Optionally, the first detecting means includes: a float member 30 disposed within the tank 20 and floatable in the direction of gravity; a first magnet 40 provided on the float member 30; in the event that the water level in the tank 20 falls to a first water line, the float member 30 falls with the water level, and the first magnet 40 approaches and triggers the second detecting means to alert the water tank 20 to the absence of water.

The float member 30 is positioned within the tank 20 and floats with the water level in the direction of gravity. The first magnet 40 is provided on the float member 30 and floats with the float member 30. When the water level is lowered, the float member 30 and the first magnet 40 are lowered with the water level. In case the water level in the water tank 20 drops to the first water line, the first magnet 40 approaches and triggers the second detecting means, so that an alarm indicates a water shortage condition in the water tank 20.

The first magnet 40 is disposed at the bottom of the float member 30 to facilitate triggering of the second detecting member in the vicinity of the second detecting member and to enhance the accuracy of the detection.

The first water line in this embodiment is determined according to the actual situation, and is not limited herein. But the first water line is positioned to take into account the actual distance the first magnet 40 can trigger the second detection member. That is, it can be understood that the first water line is located within the range where the first magnet 40 can trigger the second detecting means.

Optionally, the second detecting means includes: control means for alarming in case that the lack of water in the water tank 20 is detected and/or the water tank 20 is drawn out; the magnetic-sensitive switch 50 is electrically connected with the control device, and triggers the control device to alarm under the condition that the magnetic-sensitive switch 50 and the first magnet 40 generate magnetic induction.

In the case that the water level in the water tank 20 drops to the first water level line, the first magnet 40 approaches and magnetically induces with the magnetically sensitive switch 50, thereby triggering the control device and alarming to prompt the user of the water shortage condition of the water tank 20.

The magnetically sensitive switch 50 is electrically connected to the control device as a series circuit. The magnetically sensitive switch 50 corresponds to a control switch of the circuit and is triggered to conduct by the first magnet 40.

Optionally, the magnetically sensitive switch 50 is disposed on an inner sidewall of the accommodating cavity, so as to magnetically induce the first magnet 40, thereby improving the accuracy of detection.

Optionally, in the case that the water tank 20 and the casing 10 are assembled in place, the magnetically sensitive switch 50 is located directly under the first magnet 40, so that magnetic induction occurs with the magnetically sensitive switch 50 in time during the descending process of the first magnet 40, and the accuracy of water level detection is further improved.

Alternatively, the magnetically sensitive switch 50 is located below the water tank 20, and the magnetically sensitive switch 50 magnetically senses with the first magnet 40 in the case that the first magnet 40 descends to the first water line.

The magnetic switch 50 is located below the water tank 20, and when the first magnet 40 descends to the first water level line, the first magnet 40 can timely generate magnetic induction with the magnetic switch 50, the magnetic switch 50 is turned on, and the control device is triggered to alarm.

In addition, the magnetically sensitive switch 50 is located below the water tank 20, that is, the magnetically sensitive switch 50 is located below the first magnet 40, so that the magnetic induction between the first magnet 40 and the magnetically sensitive switch 50 can be kept under the condition that the plane of the first magnet 40 is lower than the first water line, so that the magnetically sensitive switch 50 is always in a conducting state, and then an alarm state is kept. In this way, it is possible to avoid that the first magnet 40 provided at the side portion is dislocated with the magnetically sensitive switch 50 due to the continuous drop of the water level, and the magnetically sensitive switch 50 is turned on only for a certain period of time, and the alarm cannot be continuously given.

Optionally, the third detecting means includes: the second magnet 60 is detachably connected to the bottom of the water tank 20, so that when the water tank 20 is pulled out, magnetic induction occurs between the second magnet and the magnetic switch 50 through the magnetic switch 50 to trigger the control device to alarm.

The second magnet 60 is disposed along a first direction with the magnetically sensitive switch 50, and the water tank 20 is drawn to move along the first direction. In the case before the water tank 20 is drawn out, the magnetic induction state of the magneto-sensitive switch 50 before that is absent; when the second magnet 60 passes through the magnetically sensitive switch 50 during the process of drawing the water tank 20, magnetic induction occurs between the second magnet and the magnetically sensitive switch 50, so that the magnetically sensitive state of the magnetically sensitive switch 50 is good; as the water tank 20 continues to be drawn out, the second magnet 60 continues to move outward with the water tank 20 beyond the magnetically sensitive switch 50, and the magnetically sensitive state of the magnetically sensitive switch 50 is absent. It will be appreciated that the magnetically induced state of the magnetically sensitive switch 50 experiences "none-present-not" with the water tank 20 being withdrawn. Thus, when the magnetic switch 50 is in the state, the water tank 20 is judged to be drawn out, so that the control device is triggered to give an alarm to prompt the user that the water tank 20 is drawn out.

With the tank 20 and the cabinet 10 assembled in place, the distance from the second magnet 60 to the magnetically sensitive switch 50 is greater than the safe distance over which both can magnetically induce.

The second magnet 60 is detachably connected to the bottom of the water tank 20, so as to facilitate magnetic induction with the magnetically sensitive switch 50, and to facilitate replacement and maintenance, and prevent the second magnet 60 from falling off the water tank 20 when magnetically sensed with the magnetically sensitive switch 50.

Optionally, a second magnet 60 is provided away from the open end of the receiving chamber to magnetically induce magnetic induction with the magnetically sensitive switch 50 in the event that the water tank 20 is withdrawn.

By arranging the second magnet 60 at the side of the water tank 20 facing away from the opening of the accommodating cavity, the second magnet 60 is convenient to induce magnetic induction through the magnetic switch 50 under the condition that the water tank 20 is pulled out, so that the control device is triggered to give an alarm to prompt a user that the water tank 20 is pulled out.

Optionally, in the case that the water tank 20 is assembled to the accommodating cavity of the casing 10, if the second magnet 60 protrudes out of the bottom of the water tank 20, the sidewall of the accommodating cavity is set to avoid corresponding to the position of the second magnet 60 and the moving track area thereof, so as to prevent the second magnet 60 from interfering during the moving process, and thus unnecessary loss is generated.

Alternatively, if the second magnet 60 is embedded in the bottom of the water tank 20, and when the bottom surface of the second magnet 60 is higher than or flush with the bottom surface of the water tank 20 in the case of installation of the water tank 20, the side wall of the accommodating cavity does not need to be set away from the second magnet 60, and of course, the side wall of the accommodating cavity cannot also form a protruding structure that can interfere with the second magnet 60.

Optionally, the lower surface of the second magnet 60 is higher than or flush with the upper surface of the magnetically sensitive switch 50 to avoid interference of the second magnet 60 with the magnetically sensitive switch 50 in the event that the second magnet 60 is withdrawn with the water tank 20.

By the lower surface of the second magnet 60 being higher than or flush with the upper surface of the magnetically sensitive switch 50, it is possible not only to ensure that magnetic induction occurs with the magnetically sensitive switch 50 when the second magnet 60 passes the magnetically sensitive switch 50, but also to avoid interference with the magnetically sensitive switch 50 when the second magnet 60 passes the magnetically sensitive switch 50.

It should be noted that, the lower surface of the second magnet 60 is flush with the upper surface of the magnetically sensitive switch 50, and it is understood that the lower surface of the second magnet 60 is in the same plane as the upper surface of the magnetically sensitive switch 50. In the case where the second magnet 60 passes through the magnetically sensitive switch 50, the magnetic induction generated therebetween is more intense, contributing to the enhancement of the signal.

Optionally, the water tank 20 includes: a housing 201 adapted to the opening of the receiving chamber; in the case that the water tank 20 is mounted in the receiving chamber, the outer surface of the housing 201 is flush with the outer surface of the casing 10 at the opening of the receiving chamber.

In the case that the water tank 20 is mounted in the receiving cavity of the cabinet 10, the housing 201 is exposed to the outside of the cabinet 10 so as to facilitate drawing of the water tank 20 for water injection.

The shell 201 of the water tank 20 is matched with the opening of the accommodating cavity, and under the condition that the water tank 20 is arranged in the accommodating cavity, the opening of the accommodating cavity can be closed through the shell 201, so that foreign matters can be prevented from entering the casing 10 from the opening of the accommodating cavity, and other parts are affected.

The outer surface of the shell 201 is flush with the outer surface of the casing 10 at the opening of the accommodating cavity, so that the appearance consistency of the air conditioner indoor unit is ensured, and the overall attractiveness of the air conditioner indoor unit is ensured.

It should be noted that, the outer surface of the housing 201 is flush with the outer surface of the casing 10 at the opening of the accommodating cavity, and it is understood that the outer surface of the housing 201 and the outer surface of the casing 10 are located in the same plane in the corresponding area.

Optionally, the cabinet 10 is configured with a groove 101 at an opening edge of the receiving chamber so as to separate the cabinet 10 and the housing 201, and withdraw the water tank 20.

The cabinet 10 is constructed with a groove 101 at an opening edge of the receiving chamber, and the cabinet 10 is in conformity with a surface of the housing 201 with the water tank 20 and the cabinet 10 assembled in place. The user can pull the housing 201 outwards through the groove 101, thereby realizing the pulling out of the water tank 20 from the accommodating cavity.

In addition, the groove 101 can ensure the consistency of the appearance of the casing 10 and the casing 201, and ensure the overall aesthetic degree of the indoor unit of the air conditioner.

Alternatively, the grooves 101 are arranged vertically, i.e. the length direction of the grooves 101 is vertical. Thus, the water tank 20 is pulled out of the accommodating chamber more conveniently and rapidly.

In practical applications, the length and the depth of the recess 101 may be determined according to practical situations, which are not limited herein.

Optionally, the housing 201 is configured with a window 202, the window 202 being used to view the amount of water in the tank 20.

The user can determine the water shortage condition in the water tank 20 through the cooperation of the first detection component and the second detection component, and can observe the water quantity condition in the water tank 20 through the window 202 of the shell 201.

Optionally, a scale is provided on the window 202 to allow the user to more clearly determine the water volume in the water tank 20, and to facilitate timely water filling.
