[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is for reference. Figures 1-9 This describes an indoor air conditioning unit 100 according to an embodiment of the present invention.

[0043] like Figures 1 to 3 As shown, the air conditioner indoor unit 100 according to an embodiment of the present invention includes an indoor unit body 10 and a liquid storage tank 20.

[0044] The indoor unit body 10 has a receiving space 10a inside, and the indoor unit body 10 has a liquid level display 10b and a mounting hole 10c. The mounting hole 10c is connected to the receiving space 10a. The liquid storage tank 20 includes a tank body 210 and a liquid injection part 220 connected to the tank body 210. The tank body 210 and the liquid injection part 220 are located in the receiving space 10a. The liquid injection part 220 is partially located in the mounting hole 10c. The liquid level display 10b is used to display or observe the liquid level in the tank body 210.

[0045] Depending on customer needs, the indoor unit 100 of the air conditioner can be designed to include other functions. For example, when the indoor unit 100 is an indoor unit with a humidification function, the liquid storage tank 20 can refer to a water storage tank. When water needs to be added to the water storage tank, since the liquid injection part 220 is partially located within the mounting hole 10c, water can be added to the housing 210 through the liquid injection part 220 without having to disassemble the liquid storage tank 20 separately for water addition, making the water filling operation relatively simple. Secondly, the liquid level display part 10b can be used to display the liquid level in the housing 210, or for the user to observe the liquid level in the housing 210, making it convenient for the user to know the remaining liquid level in the housing 210 in a timely manner, and to know the real-time liquid level in the housing 210 during the liquid filling process, avoiding insufficient or excessive water filling.

[0046] Secondly, the liquid storage tank 20 is installed in the accommodating space 10a of the indoor unit body 10. Since the liquid storage tank 20 does not need to be disassembled for liquid filling and is located inside the indoor unit body 10, the installation reliability of the liquid storage tank 20 can be guaranteed.

[0047] Of course, the indoor unit 100 of the air conditioner can also be an indoor unit with other functions, and correspondingly, the liquid reservoir 20 can be a liquid that provides the necessary liquid to achieve the function. For example, the indoor unit 100 of the air conditioner can have a disinfection function, and in this usage scenario, the liquid stored in the liquid reservoir 20 can be disinfectant. As another example, the indoor unit 100 of the air conditioner can have a fragrance function, and in this usage scenario, the liquid stored in the liquid reservoir 20 can be perfume.

[0048] In addition, the indoor unit 100 of the air conditioner also includes other components, such as a heat exchanger 40 and a fan assembly 50. The indoor unit 100 of the air conditioner can be a wall-mounted unit for use in bedrooms, or a floor-standing unit for use in living rooms.

[0049] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner has a receiving space 10a provided in the indoor unit body 10. The tank body 210 and the liquid injection part 220 of the liquid storage tank 20 are located in the receiving space 10a. The liquid injection part 220 is partially provided in the mounting hole 10c for convenient liquid injection operation. The liquid level display part 10b provided on the indoor unit body 10 allows the user to easily know the liquid level in the tank body 210, thereby improving the user experience.

[0050] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the indoor unit body 10 includes a frame 110 and a front panel 120 disposed on the frame 110. The front panel 120 and the frame 110 together define an accommodating space 10a. A liquid level display 10b and a mounting hole 10c are disposed on the front panel 120 or on the side of the frame 110. The positions of the liquid level display 10b and the liquid injection part 220 can be specifically set as needed. For example, if the liquid level display 10b and the mounting hole 10c are disposed on the front panel 120, and the liquid injection part 220 is installed in the mounting hole 10c, then the indoor unit 100 can perform front-facing liquid injection and liquid level observation, making the liquid injection operation more convenient. Alternatively, if the liquid level display 10b and the mounting hole 10c are disposed on the side of the frame 110, specifically on the left or right side of the frame 110, then the indoor unit 100 can perform liquid injection and liquid level observation on the left side or the right side.

[0051] In some embodiments of the present invention, such as Figure 3As shown, the injection section 220 is movably connected to the housing section 210 or the face frame 110. When the injection section 220 needs to be injected, it can be moved out of the mounting hole 10c. The ability to move the injection section 220 out of the mounting hole 10c allows for adjustment of its position during injection, facilitating the process. The injection section 220 can be movably connected to the housing section 210, moving within the housing section 210 to move out of the mounting hole 10c; alternatively, it can be movably connected to the face frame 110, moving within the face frame 110 to move out of the mounting hole 10c.

[0052] Among them, such as Figure 1 , Figure 3 As shown, the "movable connection" between the injection section 220 and the housing section 210 or the face frame 110 can mean that the injection section 220 is rotatably connected to the housing section 210 or the face frame 110, and the injection section 220 can be pulled out of the mounting hole 10c when injection is needed. Alternatively, it can mean that the injection section 220 is movably provided on the housing section 210 or the face frame 110, and the injection section 220 can be rotated out of the mounting hole 10c when injection is needed.

[0053] In some embodiments of the present invention, such as Figure 1 , Figure 3 As shown, the injection section 220 is rotated out of the mounting hole 10c. When the injection section 220 does not need to be filled with water, it is located within the receiving space 10a and fits within the mounting hole 10c. When the injection section 220 needs to be filled with water, it rotates out of the mounting hole 10c, making it convenient for the user to fill the injection section 220 with water. By rotating the injection section 220 out of or into the mounting hole 10c, both storage and filling with water are convenient.

[0054] In some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the injection section 220 and the mounting hole 10c are located at the center of the front panel 120, which is more in line with the user's usage habits and brings a better experience.

[0055] In some embodiments of the present invention, such as Figure 7 , Figure 8 As shown, the injection section 220 and the mounting hole 10c can be located on the left side of the front panel 120 or on the right side of the front panel 120, depending on the specific situation.

[0056] In some embodiments of the present invention, such as Figure 1 , Figure 4As shown, the injection section 220 is provided with a liquid inlet groove 220a, the width of which gradually increases from bottom to top, and the liquid inlet groove 220a connects to the housing section 210. The injection section 220 with this structural design can have a relatively large liquid inlet groove 220a, which is beneficial for liquid filling. Specifically, the width of the liquid inlet groove 220a can refer to... Figure 4 In terms of dimensions in the front-to-back direction, the wider part of the liquid inlet groove 220a is located at the top, and the narrower part is located at the bottom. When the liquid injection part 220 moves out of the mounting hole 10c, the wider groove ensures a greater tolerance during liquid injection, making it easier to add liquid into the liquid inlet groove 220a and to hold more liquid.

[0057] Specifically, such as Figure 4 As shown, the injection part 220 is a thin shell and is constructed in a conical shape. The injection part 220 has a front end face 220b. In the initial state, the front end face 220b of the injection part 220 is flush with the front panel 120, so that the injection part 220 and the front panel 120 are consistent in overall appearance and look more beautiful.

[0058] In some embodiments of the present invention, such as Figure 1 , Figure 5 As shown, the housing 210 has a liquid inlet 210a, and the bottom of the liquid inlet trough 220a has a liquid outlet pipe 2201. The liquid outlet pipe 2201 is located inside the liquid inlet 210a, and at least the portion of the liquid outlet pipe 2201 within the liquid inlet 210a is made of rubber. The liquid outlet pipe 2201, inserted into the liquid inlet 210a, allows for communication and installation between the liquid injection unit 220 and the housing 210. The liquid outlet pipe 2201 can be made entirely of rubber, or only the portion within the liquid inlet 210a can be made of rubber. When the liquid injection unit 220 needs to be pulled out for injection, the rubber liquid outlet pipe 2201 can elastically deform, allowing the liquid injection unit 220 to rotate relative to the housing 210. This method results in a simpler structure that is easier to manufacture and assemble.

[0059] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the outlet pipe 2201 has pleated portions 2201a on opposite sides. The pleated portions 2201a are compressed to allow the outlet pipe 2201 to rotate relative to the inlet 210a. The pleated portions 2201a include multiple pleats. When the injection section 220 needs to be pulled out for injection, the injection section 220 rotates relative to the housing section 210. By compressing the pleated portions 2201a, the outlet pipe 2201 can bend adaptively, ensuring unobstructed liquid inflow into the outlet pipe 2201.

[0060] In some embodiments of the present invention, such as Figure 5As shown, the inlet 210a extends along the length of the housing 210, and the outlet pipe 2201 is a strip-shaped pipe that also extends along the length of the housing 210. The length of the housing 210 can refer to the left-right direction in the figure. The design of the inlet 210a and the outlet pipe 2201 as long strips allows for a reduction in the thickness of the housing 210 and the outlet pipe 2201 while maintaining a large inlet and outlet cross-section (this thickness direction can refer to...). Figure 5 (in the front and rear directions), which can save internal space of the faceplate 110 and provide sufficient installation space for other components.

[0061] In some embodiments of the present invention, such as Figure 4 As shown, the box body 210 is an elongated box extending along the length of the front panel 120. The length of the front panel 120 can refer to the left-right direction in the figure. The box body 210 is designed as an elongated box, achieving a large volume while maintaining a relatively small overall thickness (the thickness direction can refer to the left-right direction in the figure). Figure 4 (in the front and back directions), thus saving internal space of the face frame 110.

[0062] In some embodiments of the present invention, such as Figure 9 As shown, the injection unit 220 includes an injection tube 2202 and a cap 2203 disposed on the injection tube 2202. When the injection unit 220 needs to be injected, the cap 2203 can open the opening of the injection tube 2202. The injection unit 220 with this structure is simple in design and easy to manufacture. In its initial state, the cap 2203 covers the opening of the injection tube 2202. When injection is needed, the cap 2203 is first removed from the opening of the injection tube 2202, and then injection is performed into the opening of the injection tube 2202. The cap 2203 can be either plugged into the opening of the injection tube 2202 or installed on the injection tube 2202 via a rotatable connection, and abuts against the opening of the injection tube 2202.

[0063] In some embodiments of the present invention, such as Figure 3 As shown, a locking assembly 30 is provided between the liquid injection section 220 and the face frame 110. The locking assembly 30 keeps the liquid injection section 220 locked to the face frame 110. When the locking assembly 30 is triggered, the liquid injection section 220 disengages from the face frame 110, allowing the liquid injection section 220 to open and be used for liquid injection. The locking assembly 30 keeps the liquid injection section 220 locked to the face frame 110 under normal conditions, preventing accidental opening during daily use. When liquid needs to be injected into the housing section 210, the locking assembly 30 is triggered again to disengage the liquid injection section 220 from the face frame 110, allowing the liquid injection section 220 to be pulled out for liquid injection.

[0064] For example, as described above, the injection section 220 can be movably mounted on the faceplate 110 in a direction perpendicular to the front panel 120. When the locking component 30 is triggered, the injection section 220 is in a free state, and the user can pull the injection section 220 out of the mounting hole 10c to inject liquid. Alternatively, the injection section 220 can be rotatably mounted on the housing section 210 in a left-right direction. When the locking component 30 is triggered, the injection section 220 is in a free state, and the user can rotate the injection section 220 to pull it out of the mounting hole 10c to inject liquid.

[0065] In some embodiments of the present invention, the locking component 30 is a snap-fit ​​component. When the injection part 220 is pressed, the snap-fit ​​component is triggered to unlock the injection part 220. The snap-fit ​​component may include a snap and a slot. For example, the snap is provided on the injection part 220, and the slot is provided on the face frame 110. As mentioned above, the injection part 220 may be supported by a rubber material. When the lower part of the injection part 220 is pressed to drive it to flip, the snap and the slot can be disengaged. This method has a simple structure and can save costs.

[0066] In some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, the liquid level display section 10b is a through hole or a viewing window that extends in the vertical direction, and at least the portion of the housing section 210 corresponding to the through hole or viewing window is made of transparent material.

[0067] In other words, the liquid level display unit 10b can be a through hole on the front panel 120, and the housing 210 can be entirely supported by a transparent material, or the part corresponding to the through hole can be made of a transparent material. This allows the user to directly observe the liquid level inside the housing 210 through the through hole, thereby knowing whether liquid needs to be added and whether the liquid level has increased to the set height. The liquid level display unit 10b can also be a viewing window on the front panel 120. The viewing window can be understood as a transparent glass window or a transparent plastic window. The housing 210 can be entirely supported by a transparent material, or the part corresponding to the viewing window can be made of a transparent material. Similarly, the liquid level inside the housing 210 can be directly known through the viewing window.

[0068] In some embodiments of the present invention, such as Figure 9 As shown, the transparent portion of the tank body 210 is provided with multiple scale bars 210b, which are spaced apart vertically. The multiple scale bars 210b allow users to accurately determine the liquid level inside the tank body 210. For example, four scale bars 210b can be provided, representing 500ml, 1000ml, 1500ml, and 2000ml respectively.

[0069] In some embodiments of the present invention, the liquid level display unit 10b is a display screen capable of displaying the liquid level inside the tank section 210. The liquid level display unit 10b can directly acquire the liquid level inside the tank section 210 through electronic display, resulting in a more accurate liquid level display. For example, a liquid level sensor is installed inside the tank section 210, and the liquid level sensor is connected to the display screen to directly display the measured liquid level data on the display screen.

[0070] The following describes a specific embodiment of the air conditioner indoor unit 100 of the present invention with reference to the accompanying drawings.

[0071] Example 1

[0072] like Figures 1 to 8 As shown, the air conditioner indoor unit 100 includes an indoor unit body 10 and a liquid storage tank 20.

[0073] The indoor unit body 10 has a receiving space 10a inside, and the indoor unit body 10 has a liquid level display 10b and a mounting hole 10c, which is connected to the receiving space 10a.

[0074] The indoor unit body 10 includes a face frame 110 and a front panel 120 disposed on the face frame 110. The front panel 120 and the face frame 110 together define an accommodating space 10a. A liquid level display 10b and a mounting hole 10c are disposed on the front panel 120. The liquid level display 10b is a through hole.

[0075] The liquid storage tank 20 includes a tank body 210 and a liquid injection section 220 communicating with the tank body 210. The tank body 210 and the liquid injection section 220 are located in the accommodating space 10a. The liquid injection section 220 is partially disposed in the mounting hole 10c. The liquid level display section 10b is used to display or observe the liquid level in the tank body 210.

[0076] The liquid injection section 220 is movably connected to the housing section 210. When the liquid injection section 220 needs to be injected, the liquid injection section 220 can be rotated out of the mounting hole 10c.

[0077] The liquid injection section 220 is provided with a liquid inlet groove 220a. The width of the liquid inlet groove 220a gradually increases from bottom to top. The liquid inlet groove 220a is connected to the box section 210.

[0078] The injection section 220 is a thin-shell part and is constructed in a conical shape. The injection section 220 has a front end face 220b. In the initial state, the front end face 220b of the injection section 220 is flush with the front panel 120.

[0079] The housing 210 is provided with a liquid inlet 210a, and the bottom of the liquid inlet 220a is provided with a liquid outlet pipe 2201. The liquid outlet pipe 2201 is located inside the liquid inlet 210a and is made of rubber material.

[0080] The liquid outlet pipe 2201 has pleated portions 2201a on opposite sides. The pleated portions 2201a are compressed by driving so that the liquid outlet pipe 2201 can rotate relative to the liquid inlet 210a.

[0081] The liquid inlet 210a extends along the length of the housing 210, and the liquid outlet pipe 2201 is a strip pipe that extends along the length of the housing 210.

[0082] A locking component 30 is provided between the injection section 220 and the face frame 110. The locking component 30 keeps the injection section 220 locked on the face frame 110. When the locking component 30 is triggered, the injection section 220 is released from the lock on the face frame 110, so that the injection section 220 can be opened and used for injection.

[0083] The locking component 30 is a snap-fit ​​component. When the injection section 220 is pressed, the snap-fit ​​component is triggered to unlock the injection section 220.

[0084] Example 2

[0085] like Figure 9 As shown, the structure of the indoor unit of the air conditioner in Embodiment 2 is roughly the same as that in Embodiment 1. The difference is that the liquid injection section 220 includes a liquid injection pipe 2202 and a cover 2203 provided on the liquid injection pipe 2202. When the liquid injection section 220 needs to be injected, the cover 2203 can open the opening of the liquid injection pipe 2202. The transparent part of the housing section 210 is provided with multiple scale bars 210b, which are spaced apart in the vertical direction.
