[0004] The air conditioner provided in this application embodiment includes a casing, an aluminum heat exchanger, and a displacement box. The aluminum heat exchanger is disposed inside the casing, and the casing includes a panel. The displacement box and the electrochromic element are both disposed on the panel. The displacement box contains a displacement agent with a metal reactivity greater than that of aluminum. The displacement agent is connected to the aluminum heat exchanger through a first wire, and the electrochromic element is connected to the aluminum heat exchanger through a second wire.

[0006] Optionally, a cover is provided above the first through hole, and the cover can switch between a state of covering the first through hole and a state of opening the first through hole.
[0007] Optionally, the cover can be flipped up and down and attached to the panel to cover or open the first through hole.
[0008] Optionally, the panel is provided with a second through hole, and mounting ears with shaft holes are provided on both the left and right sides of the second through hole; one side of the cover is provided with an extension, and the extension is provided with a rotating shaft, the extension passes through the second through hole, and the two ends of the rotating shaft are respectively inserted into the shaft holes of the mounting ears on both sides.
[0009] Optionally, when the cover covers the first through hole, there is a ventilation gap between the inner surface of the cover and the edge of the first through hole.
[0010] Optionally, the opening edge of the replacement box is provided with a hook, which is hooked onto the edge of the first through hole.
[0011] Optionally, the panel is provided with mounting holes, and the electrochromic element is installed in the mounting holes.
[0012] Optionally, the displacement box includes an insulating box and a metal box, the insulating box and the metal box are vertically connected and detachably connected; the metal of the metal box has lower metal reactivity than the displacement agent, and the bottom of the metal box is connected to the aluminum heat exchanger through the first wire.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0032] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.
[0033] This application provides an air conditioner, such as... Figures 1-12 As shown, the air conditioner includes a housing 100, an aluminum heat exchanger 200, a displacement box 300, and an electrochromic element 400. The aluminum heat exchanger 200 is disposed inside the housing 100. The housing 100 includes a panel 110, and the displacement box 300 and the electrochromic element 400 are both disposed on the panel 110. The displacement box 300 contains a displacement agent 301 with a metal reactivity greater than that of aluminum. The displacement agent 301 is connected to the aluminum heat exchanger 200 through a first wire 510, and the electrochromic element 400 is connected to the aluminum heat exchanger 200 through a second wire 520.
[0034] The housing 100 also includes a top plate, a bottom plate, a back plate, a left side plate, and a right side plate. The top plate and the bottom plate are arranged vertically opposite each other, the front panel 110 and the back plate are arranged front-to-back opposite each other, and the left side plate and the right side plate are arranged horizontally opposite each other. The top plate, the bottom plate, the front panel 110, the back plate, the left side plate, and the right side plate form a receiving cavity, in which the aluminum heat exchanger 200 is disposed.
[0035] The air conditioner provided in this application embodiment connects the displacement agent 301 to the aluminum heat exchanger 200 via a first wire 510 and the electrochromic element 400 to the aluminum heat exchanger 200 via a second wire 520. Since the metal reactivity of the displacement agent 301 is greater than that of aluminum, the displacement agent 301 will undergo electrochemical corrosion before the aluminum heat exchanger 200, thereby protecting the aluminum heat exchanger 200 from corrosion and greatly extending its service life. At the same time, the current generated by the electrochemical corrosion of the displacement agent 301 can be conducted to the electrochromic element 400, causing the color of the electrochromic element 400 to change. Thus, the user can judge whether the displacement agent 301 has been consumed based on the color of the electrochromic element 400, so as to replenish the displacement agent 301 in time when it is consumed.
[0036] Specifically, the electrochromic element 400 displays a first color when powered on and a second color when powered off. The first and second colors are different, so users can determine whether the displacing agent 301 has been consumed based on the color of the electrochromic element 400: when the electrochromic element 400 displays the first color, it means that the displacing agent 301 has not been consumed, and current is conducted to the electrochromic element 400; when the electrochromic element 400 displays the second color, it means that the displacing agent 301 has been consumed, and therefore no current is conducted to the electrochromic element 400.
[0037] For example, the electrochromic element 400 can be electrochromic glass, which appears black when energized and white when de-energized. Furthermore, gray text, such as the word "Replenish," can be provided on the electrochromic glass. When the electrochromic glass is white, the gray text will appear to prompt the user to replenish the replacement agent 301. Of course, in other embodiments, the electrochromic element 400 can also be any other device made of electrochromic material.
[0038] In some embodiments of this application, such as Figures 1-10 As shown, panel 110 has an outwardly recessed mounting groove 101, and a first through hole 102 at the top of the mounting groove 101. Replacement box 300 is disposed within the mounting groove 101, and the top of replacement box 300 has an opening 302. This design allows the user to easily add replacement agent 301 to the replacement box 300 by inserting it through the first through hole 102 into the replacement box 300 through the opening 302 at the top, without needing to remove the replacement box 300, making the operation more convenient.
[0039] Optional, such as Figure 8 and Figure 10As shown, the opening 302 of the replacement box 300 is provided with a hook 303, which is hooked onto the edge of the first through hole 102. By providing the hook 303, it is convenient to place the replacement box 300 in the mounting slot 101, and the hook 303 makes the replacement box 300 detachable, which is convenient for replacement of the replacement box 300 in the future.
[0040] In some embodiments of this application, such as Figures 4-8 As shown, a cover 120 is provided above the first through hole 102. The cover 120 can switch between covering the first through hole 102 and opening the first through hole 102. By setting the cover 120 to cover the first through hole 102, it can serve to block rain, thereby preventing rainwater from flowing into the replacement box 300 and causing adverse effects on the replacement agent 301.
[0041] Optional, such as Figure 8 As shown, when the cover 120 covers the first through hole 102, there is a ventilation gap 105 between the inner surface of the cover 120 and the edge of the first through hole 102. This arrangement allows external wind to blow in through the ventilation gap 105 to dry the displacement agent 301, thereby slowing down the electrochemical corrosion process of the displacement agent 301 and thus helping to extend the service life of the aluminum heat exchanger 200.
[0042] In some embodiments of this application, the cover 120 is flip-up and flip-down connected to the panel 110 to cover or open the first through hole 102. By flipping the cover 120 up and down and connecting it to the panel 110, it is convenient to control whether the cover 120 covers or opens the first through hole 102, and the cover 120 is not easily lost. Specifically, under normal circumstances, the cover 120 covers the first through hole 102. When it is necessary to replenish the replacement agent 301 into the replacement box 300, the cover 120 is flipped upward to open the first through hole 102, and the replacement agent 301 is put into the replacement box 300 through the opening 302 at the top of the replacement box 300. After the replacement agent 301 has been replenished, the cover 120 is flipped downward to cover the first through hole 102.
[0043] Optional, such as Figure 9 and Figure 10 As shown, the panel 110 is provided with a second through hole 103, and mounting ears 104 with shaft holes are provided on both the left and right sides of the second through hole 103; as Figure 11As shown, one side of the cover 120 has an extension 121, and a rotating shaft 122 is provided on the extension 121. The extension 121 passes through the second through hole 103, and both ends of the rotating shaft 122 are respectively inserted into the shaft holes of the mounting ears 104 on both sides. By setting the rotating shaft 122 to cooperate with the shaft holes of the mounting ears 104, the cover 120 can be connected to the panel 110 in a way that allows it to be flipped up and down; at the same time, the extension 121 passing through the second through hole 103 can prevent rainwater from entering the interior of the housing 100 through the second through hole 103.
[0044] In some embodiments of the application, the displacement box 300 includes an insulating box body made of insulating material and a metal box body made of metal material. The insulating box body and the metal box body are vertically connected and detachably connected. The metal reactivity of the metal box body is lower than that of the displacement agent 301. The bottom of the metal box body is connected to the aluminum heat exchanger 200 through a first wire 510. It can be understood that one end of the first wire 510 is indirectly connected to the displacement agent 301 through the metal box body, and the other end of the first wire 510 is connected to the aluminum heat exchanger 200, thereby realizing the connection between the displacement agent 301 and the aluminum heat exchanger 200.
[0045] This application reduces costs by using an insulating box and a metal box in the replacement box 300. Since the insulating box does not corrode, the cost is lowered. By detachably connecting the insulating box and the metal box, when the metal box corrodes, the two boxes can be separated for replacement with a new metal box. Optionally, the insulating box can be made of lightweight insulating materials such as plastic, leather, or non-woven fabric.
[0046] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the panel 110 has mounting holes 106, and the electrochromic element 400 is installed in the mounting holes 106, thereby enabling the electrochromic element 400 to be mounted on the housing 100. Optionally, the electrochromic element 400 can be pasted into the mounting holes 106, or the electrochromic element 400 can be embedded in the mounting holes 106, or the electrochromic element 400 can be installed in the mounting holes 106 by welding or snap-fit.
[0047] In some embodiments of this application, such as Figures 1-5As shown, the air conditioner also includes a metal partition 600, which is located between the panel 110 and the heat exchanger and contacts the aluminum heat exchanger 200. A displacement agent 301 is connected to the partition 600 via a first wire 510, and an electrochromic element 400 is connected to the partition 600 via a second wire 520. It can be understood that one end of the first wire 510 is indirectly connected to the aluminum heat exchanger 200 through the partition 600, and the other end of the first wire 510 is connected to the displacement agent 301, thereby achieving the connection between the displacement agent 301 and the aluminum heat exchanger 200. This also reduces the length of the first wire 510, lowering costs.
[0048] Optionally, a fixing structure can be provided on the panel 110 and the partition 600. The fixing structure can be a wire channel, a wire clip, or tape, etc. The fixing structure can fix the first wire 510 and the second wire 520 to facilitate the connection of the first wire 510 with the partition 600 and the displacement agent 301, and to facilitate the connection of the second wire 520 with the electrochromic element 400 and the partition 600.
[0049] It is understood that the air conditioner provided in this application embodiment can be an integrated air conditioner (e.g., a window air conditioner) or a split air conditioner, which includes an indoor unit and an outdoor unit. When the air conditioner is a split air conditioner, the aluminum heat exchanger 200 can be the indoor heat exchanger of the indoor unit, and the panel 110 can be the panel of the indoor unit; or, the aluminum heat exchanger 200 can be the outdoor heat exchanger of the outdoor unit, and the panel 110 can be the panel of the outdoor unit.
[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
