The water tank provided in the embodiment of the present application can be pulled out and installed in the casing of the equipment. The equipment used for the pull-out installation of the water tank can be an air conditioner with an air cleaning function, an air purifier, or an air conditioner. Equipment equipped with a water tank that requires frequent refilling of water. The water tank has a pull-out end, which is the end that is first pulled out from the casing of the equipment when the water tank is pulled out from the casing of the equipment.

As shown in Figures 1 and 2, the water tank provided by the embodiment of the present application includes a tank body 100 and a cover body 200 covering the tank body 100. The tank body 100 has a water storage cavity 110. That is to say, the bottom of the box 100 and the surrounding side walls form a water storage chamber 110. The upper part of the box 100 is an opening, and the cover 200 covers the upper part of the box 100. A water injection port 220 is provided on the side of the cover 200 close to the pull-out end. The water injection port 220 is connected with the water storage chamber 110 , and water can be injected into the water storage chamber 110 from the water injection port 220 .

In the related art, for example, taking a water tank in an air-conditioning indoor unit as an example, the cover 200 is provided with an air outlet 230 , and the air outlet 230 is provided in the middle of the cover 200 and close to the second end of the cover 200 , the second end is the end of the water tank opposite to the pull-out end. The box 100 of the water tank is provided with an air inlet 120. The air inlet 120 is provided on the side wall of the box 100 away from the pull-out end. When adding water to the water tank, it needs to be completely The water tank is pulled out from the casing of the air conditioner indoor unit, and then water is added into the water tank from the air outlet 230 or the air inlet 120. This process is complicated, time-consuming and labor-intensive. In order to facilitate water filling at the air inlet 120 of the water tank, the air inlet 120 is tilted toward the outside of the water tank. This arrangement occupies the space in the casing of the air conditioner indoor unit and reduces the volume of the water tank.

The water tank provided in the embodiment of the present application is provided with a water filling port 220 on the side of the cover 200 close to the pull-out end. When the water tank needs to be filled with water, it is only necessary to slightly pull out a part of the device casing to expose the water filling port 220. That is, it can add water to the water tank without completely pumping out the water tank. It is convenient to add water and simple to operate. Moreover, water is added to the water tank from the water filling port 220, and there is no need to use the air inlet 120. Therefore, the air inlet 120 in the embodiment of the present application is a window opened on the side wall of the box 100 away from the pull-out end, and it does not need to be opened to the outside of the water tank. Inclined, this setting can increase the volume of the water tank to increase the volume of the water tank, thereby increasing the amount of water stored in the water tank, thus reducing the frequency of filling the water tank.

In order to avoid water overflow when the water tank is filled with water, an indicator 300 is provided at the water filling port 220 , and the indicator 300 is used to indicate the amount of water in the water storage chamber 110 . When the indicator 300 indicates that the amount of water in the water tank is small, the speed of adding water can be increased. When the indicator 300 indicates that the water in the water tank is almost full, the speed of adding water can be slowed down to prevent water overflow caused by excessive water addition. For example, the indicator 300 may be a water float, a sensor, etc.

In some embodiments of the present application, a side of the cover 200 close to the pull-out end is provided with a water filling tank 210 that sinks into the water storage chamber 110. The water filling port 220 is provided at the bottom of the water filling tank 210. The water storage chamber 110 is provided with It is convenient to add water to the water tank. When adding water to the water tank, water can be directly added to the water filling tank 210, and then the water flows from the water filling port 220 at the bottom of the water tank 210 to the water storage chamber 110. This setting prevents water from spilling into the water tank. outside.

In some embodiments of the present application, for example, as shown in Figures 3, 4 and 5, the bottom of the water tank 210 is also provided with a through hole 214, and the indicator 300 includes a floating part 310, a connecting part 310 connected in sequence. The connecting part 320 and the indicating part 330, the connecting part 320 penetrates through the bottom of the water filling tank 210 from the through hole 214, and the connecting part 320 is rotatably connected to the cover 200, the floating part 310 is located in the water storage chamber 110, and the indicating part 330 Located in the water tank 210. That is to say, the connecting part 320 passes through the bottom of the water filling tank 210 from the through hole 214, part of the connecting part 320 is located in the water storage chamber 110, part of the connecting part 320 is located in the water filling tank 210, and one end of the connecting part 320 is connected to The floating part 310 is located in the water storage chamber 110 , and the indicating part 330 connected to the other end of the connecting part 320 is located in the water filling tank 210 .

When the water storage chamber 110 is filled with water, the water level in the water storage chamber 110 gradually rises. As the water level in the water storage chamber 110 rises, the floating part 310 moves between the connecting part 320 and the cover 200 under the action of the buoyancy of the water. The rotation connection point is the rotation center and rotates toward the side closer to the cover 200 . Under the action of the floating portion 310 , the indicator portion 330 uses the rotation connection point between the connection portion 320 and the cover 200 as the rotation center toward the bottom of the tank 210 . Turn on one side. That is to say, the connecting part 320 in the middle is rotatably connected to the cover 200, and the floating part 310 at one end of the connecting part 320 rotates around the rotational connection point between the connecting part 320 and the cover 200, which will drive the indicator at the other end of the connecting part 320. The portion 330 rotates around the rotational connection point between the connecting portion 320 and the cover 200 .

The relative position between the indicator part 330 and the bottom of the water filling tank 210 can indicate the amount of water in the water storage chamber 110. When the angle between the indicator part 330 and the bottom of the water filling tank 210 is large, the amount of water in the water storage chamber 110 The amount of water is small. As the amount of water in the water storage chamber 110 increases, the floating part 310 rotates to the side closer to the cover 200 under the action of the buoyancy of the water, and the indicating part 330 moves to the side close to the bottom of the water filling tank 210 Rotate, so that the angle between the indicator part 330 and the bottom of the water tank 210 becomes smaller. When the angle between the indicator part 330 and the bottom of the water tank 210 decreases to the preset value, the water in the water storage chamber 110 Top up the water. When the angle between the indicator part 330 and the bottom of the water filling tank 210 is reduced to a certain extent, the user can slow down the water filling speed to prevent the water filling tank 210 from still storing a large amount of water when the water storage chamber 110 is full. Water, when the water storage chamber 110 is filled with water, there is still a large amount of water in the water filling tank 210, which will cause too much water to be added to the water storage chamber 110, affecting the work of the water tank, or too much water will be added to the water storage chamber 110. Water flows out from the following overflow outlets, causing a waste of water resources and increasing the work of cleaning up the overflow water.

Optionally, the through hole 214 is a rectangular hole, and the through hole 214 is provided on one side of the water injection port 220 and on a side of the water injection port 220 away from the pulling end. The two side surfaces of the connecting portion 320 along the first direction are respectively in contact with the two side walls of the through hole 214 along the first direction, and the first direction is parallel to the pull-out end. That is to say, the length of the connecting portion 320 along the first direction matches the length of the through hole 214 along the first direction, and the two are rotatably fitted.

When the water storage chamber 110 is filled with water, the floating part has upward buoyancy, so the indicating part 330 has a downward force, so that the indicating part 330 is in close contact with the bottom of the water filling tank 210, thereby blocking the water filling port 220 and preventing the water filling port 220 from being blocked. The water in the water filling tank 210 continues to be added into the water storage chamber 110 from the water filling port 220 . At the same time, under the action of the buoyancy force of the floating part, the connecting part 320 located at the upper part of the through hole 214 is in close contact with the edge of the upper part of the through hole 214 close to the water injection port 220 , and the connecting part 320 located at the lower part of the through hole 214 is in close contact with the through hole 214 The lower edge away from the water filling port 220 is in close contact, so that the connecting portion 320 blocks the through hole 214 to prevent the water in the water filling tank 210 from flowing from the through hole 214 into the water storage cavity 110 .

When the water storage chamber 110 is filled with water, the water filling port 220 and the through hole 214 are blocked, so that the water in the water filling tank 210 cannot continue to flow into the water storage chamber 110, which effectively prevents excessive water from being added into the water storage chamber 110. In addition, during the operation of the water tank, the amount of water in the water storage chamber 110 gradually decreases, the water filling port 220 and the through hole 214 are reopened, and the water in the water filling tank 210 can flow into the water storage chamber 110 again. That is to say, the water tank 210 can serve as a temporary storage of water. Of course, at this time, the indicator 300 is also needed to indicate the amount of water in the water storage tank to prevent too much water from being added to the water tank 210. Adding too much water to the water tank 210 will cause the water to overflow from the notch of the water tank 210, or The water flows from the leakage pipe 212 described below into the water storage cavity 110, and then flows out from the overflow outlet described below, causing a waste of water resources and increasing the work of cleaning up the overflow water.

In some embodiments of the present application, two mounting parts 240 are provided on the side of the cover 200 facing the water storage chamber 110 , and the two mounting parts 240 are provided oppositely on both sides of the through hole 214 along the first direction. That is to say, the two mounting members 240 are spaced apart along the first direction and are oppositely arranged on opposite sides of the through hole 214 . Each mounting piece 240 includes a connecting section 241 connected to the cover 200 and a mounting section 242 opposite to the cover 200 . An installation space for installing the connecting portion 320 is formed between the mounting section 242 and the cover 200 . The connecting part 320 is located between the two mounting parts 240, and the connecting part 320 is provided with rotating shafts 321 on both sides along the first direction. The two rotating shafts 321 are respectively rotatably connected between the two mounting sections 242 and the cover 200. . That is to say, the connecting part 320 is rotatably installed on the cover 200 through two rotating shafts 321 .

Optionally, a first installation groove 2421 is provided on the side of the installation section 242 facing the cover 200 , and a second installation groove 213 corresponding to the first installation groove 2421 is provided on the side of the cover 200 facing the installation section 242 . The rotating shaft 321 It is rotatably installed in the first mounting groove 2421 and the second mounting groove 213. The first mounting groove 2421 and the second mounting groove 213 play a limiting role on the rotating shaft 321, so that the rotating shaft 321 can only move in the first mounting groove 2421 and the second mounting groove 213. Rotation occurs in the second mounting groove 213 .

Optionally, each mounting part 240 also includes a reinforcing part 243. The reinforcing parts 243 of the two mounting parts 240 are arranged oppositely, and the connecting part 320 is located between the two reinforcing parts 243.

In order to increase the tightness of the connecting part 320 in blocking the through hole 214 , a blocking boss 322 is provided on the side of the connecting part 320 away from the water injection port 220 . The blocking boss 322 is located between the two rotating shafts 321 . When the water storage cavity 110 is filled with water, the blocking boss 322 is in close contact with the edge of the lower part of the through hole 214 away from the water injection port 220. That is to say, under the action of the buoyancy force of the floating part, the edge of the upper part of the through hole 214 is closed. The connecting part 320 is in close contact with the edge of the upper part of the through hole 214 close to the water injection port 220, and the blocking boss 322 is in close contact with the edge of the lower part of the through hole 214 away from the water injection port 220, so that the connection part 320 blocks the through hole 214. This prevents water in the water tank 210 from flowing into the water storage cavity 110 from the through hole 214 .

In some embodiments of the present application, the floating part 310 includes a shell connected to the connecting part 320 and a floating component disposed in the housing. The density of the floating component is smaller than the density of water, so that the floating component can float in the water. Optionally, the opening of the housing faces the lower part of the water storage chamber 110. This arrangement makes it difficult for the floating member to fall off from the housing.

In some embodiments of the present application, the water filling tank 210 includes a first tank area close to the bottom of the water adding tank 210 and a second tank area close to the slot mouth of the water adding tank 210. The first tank area and the second tank area cooperate to form It has an inverted "convex" shape structure, and the water injection port 220 is arranged in the first groove area. This arrangement reduces the distance between the water injection port 220 and the bottom of the water storage chamber 110, and reduces the impact of the water flowing in from the water injection port 220 on the bottom of the water storage chamber 110 when water is added to the water storage chamber 110. The bottom of the cavity 110 serves as a protector.

In order to prevent too much water from being added into the water storage chamber 110 and affecting the operation of the water tank, an overflow port is provided on the side wall of the box body 100. The overflow port connects the outside of the box body 100 and the water storage chamber 110. In the water storage chamber 110 When too much water is added, the water will overflow from the overflow port, ensuring that the water level in the water storage chamber 110 will not exceed the maximum water level of the water storage chamber 110 . And the end surface of the second tank area close to the first tank area forms a convex table surface 211. A water leakage port is provided on the convex table surface 211. The water leakage port is connected with the water storage chamber 110. This arrangement prevents the water in the water filling tank 210 from being added too much. The water in the water tank 210 overflows from the slot of the water tank 210. When too much water is added in the water tank 210, the water in the water tank 210 will leak from the leakage port into the water storage chamber 110. After the water leaks from the leakage port into the water storage chamber 110, there will be too much water in the water storage chamber 110. At this time, the excess water in the water storage chamber 110 flows out from the overflow port. This arrangement makes the water tank set An overflow port can prevent excessive water from being added into the water storage chamber 110 and the filling tank 210 .
