DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.
[0026] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] 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.
[0028] This application provides an air conditioner, such as... Figures 1 to 7 As shown, the air conditioner includes a casing 100, an aluminum heat exchanger 200, a displacement box 300, and an electrochromic element 400. The aluminum heat exchanger 200 is disposed inside the casing 100. The casing 100 includes a top plate 110. The displacement box 300 and the electrochromic element 400 are both disposed on the top plate 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. The electrochromic element 400 is connected to the aluminum heat exchanger 200 through a second wire 520.
[0029] The housing 100 also includes a bottom plate, a front plate, a back plate, a left side plate, and a right side plate. The top plate 110 is arranged vertically opposite to the bottom plate, the front plate and the back plate are arranged front-to-back opposite to each other, and the left side plate and the right side plate are arranged horizontally opposite to each other. The top plate 110, the bottom plate, the front plate, 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.
[0030] The air conditioner provided by the embodiments of the present application connects the displacer 301 and the aluminum heat exchanger 200 through the first wire 510, and connects the electrochromic device 400 and the aluminum heat exchanger 200 through the second wire 520. Since the metal liveness of the displacer 301 is greater than that of aluminum, the displacer 301 will be electrochemically corroded before the aluminum heat exchanger 200, thereby protecting the aluminum heat exchanger 200 from corrosion and greatly prolonging the service life of the aluminum heat exchanger 200. Meanwhile, the current generated by the electrochemical corrosion of the displacer 301 can be conducted to the electrochromic device 400, so that the color of the electrochromic device 400 changes, thereby enabling the user to determine whether the displacer 301 is consumed according to the color of the electrochromic device 400, so as to replenish the displacer 301 in time when the displacer 301 is consumed.
[0031] Specifically, the electrochromic device 400 presents a first color in a powered state and presents a second color in a powered-off state, and the first color and the second color are different, thereby enabling the user to determine whether the displacer 301 is consumed according to the color of the electrochromic device 400. When the electrochromic device 400 presents the first color, it indicates that the displacer 301 is not consumed, and at this time, the current is conducted to the electrochromic device 400. When the electrochromic device 400 presents the second color, it indicates that the displacer 301 is consumed, and therefore, the current is not conducted to the electrochromic device 400.
[0032] For example, the electrochromic device 400 can be electrochromic glass. The electrochromic glass presents black in the powered state and presents white in the powered-off state. In addition, a gray word, for example, the word “replenish” in gray, can be arranged on the electrochromic glass. When the electrochromic glass presents white, the gray word appears, prompting the user to replenish the displacer 301. Of course, in other embodiments, the electrochromic device 400 can also be other devices made of electrochromic material.
[0033] In some embodiments of the present application, as shown in Figures 3 to 6 The top plate 110 is provided with a mounting hole 111, and the displacement box 300 is mounted in the mounting hole 111. The top of the displacement box 300 is provided with an opening 302. The electrochromic device 400 is arranged above the mounting hole 111 and can be switched between a state of covering the mounting hole 111 and a state of opening the mounting hole 111. By arranging the electrochromic device 400 to cover the mounting hole 111, the effect of rain blocking can be achieved, thereby preventing rainwater from flowing into the displacement box 300 from the mounting hole 111 to cause adverse effects on the displacer 301. When it is necessary to replenish the displacer 301, the user can switch the electrochromic device 400 to the state of opening the mounting hole 111, and put the displacer 301 into the displacement box 300 through the opening 302 at the top of the displacement box 300, which is convenient to operate.
[0034] Optionally, as shown inFigure 3 , Figure 4 and Figure 6 As shown, a water-blocking protrusion 112 is provided around the outer periphery of the mounting hole 111, and the replacement box 300 is detachably connected to the side wall of the water-blocking protrusion 112. This application provides a water-blocking protrusion 112 around the outer periphery of the mounting hole 111, which serves to prevent rainwater from flowing into the replacement box 300 through the gap between the electrochromic element 400 and the end face of the mounting hole 111, thus preventing it from adversely affecting the replacement agent 301. Furthermore, the detachable connection between the replacement box 300 and the side wall of the water-blocking protrusion 112 facilitates the installation and removal of the replacement box 300.
[0035] Optional, such as Figure 6 and Figure 7 As shown, the side wall of the water-blocking protrusion 112 is provided with a locking hole 113, and the edge of the opening 302 of the replacement box 300 is provided with a spring buckle 303, which engages with the locking hole 113. This application achieves a detachable connection between the replacement box 300 and the water-blocking protrusion 112 by engaging with the spring buckle 303 and the locking hole 113. Furthermore, the engagement structure of the spring buckle 303 and the locking hole 113 facilitates the installation and removal of the replacement box 300 and the water-blocking protrusion 112.
[0036] Optional, such as Figures 4 to 6 As shown, the electrochromic element 400 has a water-retaining flange 401 around its periphery. When the electrochromic element 400 covers the mounting hole 111, the water-retaining flange 401 surrounds the outer periphery of the water-retaining protrusion 112. By providing a water-retaining flange 401 around the periphery of the electrochromic element 400, this application can effectively prevent rainwater from flowing into the replacement box 300 through the gap between the electrochromic element 400 and the water-retaining protrusion 112, thus preventing it from adversely affecting the replacement agent 301.
[0037] In some embodiments of this application, the electrochromic element 400 is connected to the top plate 110 in a flip-up manner to cover or open the mounting hole 111. By connecting the electrochromic element 400 to the top plate 110 in a flip-up manner, it is convenient to control the electrochromic element 400 to cover or open the mounting hole 111, and the electrochromic element 400 is not easily lost.
[0038] Specifically, under normal circumstances, the electrochromic element 400 covers the mounting hole 111. When it is necessary to add replacement agent 301 to the replacement box 300, the electrochromic element 400 is flipped upward to open the mounting hole 111, 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 is replenished, the electrochromic element 400 is flipped downward to cover the mounting hole 111.
[0039] Optional, such as Figure 2 and Figure 3 As shown, a bracket 114 is provided on the top plate 110, and both ends of the bracket 114 are provided with mounting parts having shaft holes; the electrochromic element 400 is provided with a rotating shaft 402, and both ends of the rotating shaft 402 are respectively inserted into the shaft holes of the two mounting parts. By setting the rotating shaft 402 to cooperate with the shaft holes of the mounting parts, the electrochromic element 400 can be connected to the top plate 110 in a way that allows it to be flipped up and down.
[0040] Optional, such as Figures 2 to 6 As shown, the electrochromic element 400 includes an electrochromic part 410 and an insulating frame 420 surrounding the electrochromic part 410. The electrochromic part 410 is connected to an aluminum heat exchanger 200 via a second wire 520. The insulating frame 420 is rotatably connected to the top plate 110. A rotating shaft 402 is located on the outer side of the insulating frame 420, and a water-blocking flange 401 is located at the periphery of the insulating frame 420.
[0041] Specifically, the electrochromic unit 410 displays a first color when powered on and a second color when powered off. Since the first and second colors are different, users can determine whether the replacement agent 301 has been consumed based on the color of the electrochromic unit 410.
[0042] In some embodiments of this application, such as Figures 4 to 7 As shown, the displacement box 300 includes an insulating box body 310 made of insulating material and a metal box body 320 made of metal material. The insulating box body 310 and the metal box body 320 are vertically connected and detachably connected. An opening 302 is provided on the insulating box body 310. The metal reactivity of the metal box body 320 is lower than that of the displacement agent 301. The bottom of the metal box body 320 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 320, 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.
[0043] This application provides a replacement box 300 comprising an insulating box body 310 and a metal box body 320. Since the insulating box body 310 does not corrode, costs can be reduced. By detachably connecting the insulating box body 310 and the metal box body 320, when the metal box body 320 corrodes, it can be separated from the insulating box body 310 to replace it with a new metal box body 320. The insulating box body 310 can be made of lightweight insulating materials such as plastic, leather, or non-woven fabric.
[0044] Optional, such as Figure 7As shown, one of the insulating box 310 and the metal box 320 is provided with a buckle 304, and the other is provided with a slot. The buckle 304 and the slot engage in a snap-fit connection. By setting the insulating box 310 and the metal box 320 to engage with the slot via the buckle 304, the insulating box 310 and the metal box 320 can be detachably connected. Moreover, the structure of the buckle 304 engaging with the slot facilitates the installation and removal of the insulating box 310 and the metal box 320.
[0045] Specifically, the insulating box 310 may have a buckle 304 and the metal box 320 may have a slot, with the buckle 304 on the insulating box 310 engaging with the slot on the metal box 320; or, the metal box 320 may have a buckle 304 and the insulating box 310 may have a slot, with the buckle 304 on the metal box 320 engaging with the slot on the insulating box 310. The specific configuration can be determined according to actual needs.
[0046] Optional, combined Figure 4 and Figure 7 As shown, the inner wall of the insulating housing 310 has a guide slope 311 that slopes towards the metal housing 320. By providing the guide slope 311, this application facilitates the automatic collection of the displacer 301 that is broken during air conditioning operation into the metal housing 320.
[0047] In some embodiments of this application, such as Figure 5 As shown, the aluminum heat exchanger 200 includes a heat exchanger body and an end plate 210. The end plate 210 is disposed at the end of the heat exchanger body, and the displacing agent 301 is connected to the end plate 210 through a first wire 510.
[0048] Optionally, a fixing structure 600 is provided on the aluminum heat exchanger 200, the displacement box 300, and the electrochromic element 400. The fixing structure 600 can be a wire channel, a wire clip 304, or tape, etc. The fixing structure 600 fixes the first wire 510 and the second wire 520 to facilitate the connection of the first wire 510 to the aluminum heat exchanger 200 and the displacement agent 301, and to facilitate the connection of the second wire 520 to the aluminum heat exchanger 200 and the electrochromic element 400.
[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 top plate 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 top plate 110 can be the panel of the outdoor unit.
