Detailed Description

Various embodiments of the present application will now be described with reference to the accompanying drawings, which form a part hereof. It should be understood that although directional terms such as "front," "rear," "upper," "lower," "left," "right," and the like may be used herein to describe various example structural portions and elements of the application, these terms are used herein for convenience of description only and are to be determined based on the example orientations shown in the drawings. Because the embodiments disclosed herein can be arranged in a variety of orientations, these directional terms are used for purposes of illustration only and are not to be construed as limiting.

Fig. 1A is a perspective view of an embodiment of an air conditioner 100 according to the present application, and fig. 1B is an exploded view of the air conditioner 100 shown in fig. 1A, for illustrating the overall structure and specific components of the air conditioner 100. As shown in fig. 1A and 1B, the air conditioner 100 includes a housing 101, a filter assembly 102, a coil 108, and a fan assembly 107. Wherein the coil 108 and fan assembly 107 are enclosed within the housing 101.

The housing 101 is generally rectangular parallelepiped shaped having oppositely disposed left and right side portions 182, 184, and oppositely disposed front and rear side portions 183, 185. The left side 182 of the housing is provided with a housing inlet 151 and the right side 184 of the housing is provided with a housing outlet 152. The rear side 185 of the housing is closed. The front side 183 of the housing is provided with an access opening 109, and the front side 183 of the housing is provided with a coil cover plate 121 at a position adjacent to the access opening 109, so that the access opening 109 and the coil cover plate 121 are arranged side by side.

The filter assembly 102 is disposed at the housing inlet 151 to filter air entering the air conditioner 100. The filter assembly 102 includes a filter fixing frame 153 and a filter 154. The filter 154 is fixed to the housing inlet 151 by a filter fixing frame 153. The filter 154 is formed of a filter material such as a nonwoven fabric fiber mat. The outside air is filtered by the filter 154 and then enters the inside of the case 101.

A coil 108 is disposed within the housing 101 and adjacent the filter assembly 102 for heat exchange with the filtered air to heat or cool the filtered air. When the coil 108 is in place in the housing 101, the coil 108 is directly against the coil cover 121 on the front side 183 of the housing. Coil 108 has inlet tube 105 and outlet tube 104. An inlet pipe 105 and an outlet pipe 104 extend out of the housing 101, and the heat exchange medium enters the coil 108 via the inlet pipe 105 and exits the coil 108 via the outlet pipe 104. Specifically, coil openings 158 and 157 are provided in coil cover 121, and coil openings 158 and 157 are sized to match the size of inlet tube 105 and outlet tube 104, respectively. Inlet tube 105 and outlet tube 104 may extend through coil cover plate 121 through respective coil openings 158 and 157, respectively, to connect to a supply of heat exchange medium.

The fan assembly 107 is located within the housing 101 between the coil 108 and the left side 182 of the housing 101. The fan assembly 107 includes a fan 155 and a motor 156, the motor 156 driving the fan 155 to rotate. The outlet of the fan 155 is connected to the housing outlet 152. The external air is filtered by the filter 154 and then heated or cooled by heat exchange with the heat exchange medium in the coil 108 by the fan 155. The heated or cooled air then flows through the fan 155 and is eventually discharged from the air conditioner 100 through the housing outlet 152. Thus, the air conditioner 100 can filter and purify air and can adjust the temperature of the air.

With continued reference to fig. 1B, the access opening 109 is generally square shaped and is formed by an opening in the front side 183 of the housing 101. The access opening 109 is positioned proximate to the fan assembly 107 and the coil 108 so that an operator can access the fan assembly 107 and the coil 108 through the access opening 109 and inspect and repair the same. In the air conditioner 100, the fan assembly 107 and the coil 108 are relatively failure-prone components, which often require inspection or maintenance, and maintenance is facilitated by the provision of the access opening 109. The access opening 109 has an upper edge 173 and a lower edge 174 in the height direction H of the housing 101, and a left edge 172 and a right edge 171 in the width direction W of the housing 101.

The air conditioner 100 further includes an access door 120, a holder 110, and a fastener 130. The access door 120 is substantially square and has a size that matches the size of the access opening 109 to cover the access opening 109. The retainer 110 is disposed at the right edge 171 of the access opening 109 and may be integrally formed with the coil cover plate 121 from sheet metal. The access door 120 can close the access opening 109 by cooperation with the holder 110 and the fastener 130 to enclose components inside the casing 101 when the air conditioner 100 is in normal use.

Fig. 2 is a perspective view of the access door 120 in fig. 1B. As shown in fig. 2, the access door 120 is provided at an outer periphery thereof with a flange 240 folded outward, and the flange 240 includes an upper flange 243, a lower flange 244, a left flange 242, and a right flange 241. The access door 120 is sized such that when the access door 120 is installed in place on the access opening 109, the upper flange 243 of the access door 120 is positioned above the upper edge 173 of the access opening 109, the lower flange 244 of the access door 120 is positioned below the lower edge 174 of the access opening 109, the left flange 242 of the access door 120 is positioned to the left of the left edge 172 of the access opening 109, and the right flange 241 of the access door 120 does not extend beyond the right edge 171 of the access opening 109, but rather abuts the retainer 110 at the right edge 171 of the access opening 109. The right flange 241, the upper flange 243, and the lower flange 244 of the access door 120 can press the right side of the access door 120 against the access opening 109 by cooperation with the holder 110. The left side of the access door 120 is provided with a hole 231, the housing 101 is provided with a corresponding threaded hole 132, and the fastener 130 is engaged with the threaded hole 132 through the hole 231 to press the left side of the access door 120 against the access opening 109, thereby encapsulating the access opening 109 through the access door 120.

Fig. 3 is a perspective view of another perspective of the air conditioner 100 shown in fig. 1A with the access door 120 removed to more clearly show the retainer 110. A detailed structure of the holder 110 is shown in detail in a partially enlarged view of a dashed frame portion in fig. 3. As shown in fig. 3, the holder 110 has a main body 313 and a hook 311, and the hook 311 has a bent portion 315 and is connected to the main body 313 by the bent portion 315 (this will be more clearly shown in fig. 4).

The main body 313 extends outwardly from the housing 101 as seen in the longitudinal direction L of the housing, and then the hook 311 extends obliquely towards the service opening 109 by the turning transition of its bent portion 315, so that the cross section of the holder 110 formed by the main body 313 and the hook 311 together is substantially "J" shaped. The hook portion 311 and the body portion 313 form an accommodating space 316 therebetween for accommodating the right flange 241 of the access door 120.

The holder 110 is substantially elongated as viewed in the height direction H of the housing 101, extends along the right edge 171 of the access opening 109, and the holder 110 extends in the height direction of the access door 120 when the access door 120 is mounted in place. In the present embodiment, the main body portion 313 and the hook portion 311 of the holder 110 synchronously extend for the same distance in the height direction H of the housing 101, which makes any cross section of the holder 110 "J" shaped. In contrast to the upper edge 173 of the access opening 109, the retainer 110 extends flush with the upper edge 173 or above the upper edge 173. The holder 110 extends to be flush with the lower edge 174 or to extend below the lower edge 174, compared to the lower edge 174 of the access opening 109, but the distance that the holder 110 extends in the height direction H of the housing 101 is slightly smaller than the distance between the upper flange 243 and the lower flange 244 of the access door 120. Therefore, when the access door 120 is mounted in place, the upper end and the lower end of the hook 311 can abut against the upper flange 243 and the lower flange 244 of the access door 120, so that the access door 120 is positioned in the height direction of the housing 101. In other embodiments, the body portion 313 may not extend in synchronization with the hook 311, only the hook 311 extends to be flush with or above the upper edge 173 of the access opening 109 and to be flush with or below the lower edge 174, and the hook 311 extends in the height H direction of the housing 101 a distance slightly less than the distance between the upper and lower flanges 243, 244 of the access door 120. In such an embodiment, the upper and lower ends of the hook 311 can also abut against the upper flange 243 and the lower flange 244 of the access door 120, so as to ensure the positioning of the access door 120 in the height direction of the housing 101, so that the access door 120 covers the access opening 109 as desired. In addition, the upper and lower ends of the hook 311 abut against the upper and lower flanges 243 and 244 of the access door 120 to also help hold the access door 120 on the access opening 109.

Fig. 4 is a plan view of the air conditioner 100 shown in fig. 1A, in which the access door 120 is in a closed state. As shown in fig. 4, when the access door 120 is mounted in place, the right flange 241 of the access door 120 is located in the accommodation space 316 between the hook portion 311 and the main body portion 313 of the holder 110, and the outer side surface of the right flange 241 abuts against the main body portion 313 of the holder 110. The distance from the inner side surface of the bent portion 315 of the hook 311 to the end of the main body 313 connected to the housing is slightly smaller than the width of the right flange 241 of the access door 120, so that the end of the right flange 241 of the access door 120 presses the inner side surface of the bent portion 315 of the holder 110 when the access door is mounted in place. The holder 110 is formed entirely of a sheet metal member and thus has a certain elasticity. When the end of the right flange 241 of the access door 120 presses the inner side of the bent portion 315 of the holder 110, the bent portion 315 can be deformed to some extent and apply a pressing force to the right flange 241 of the access door 120, thereby pressing the right side of the access door 120 against the access opening 109.

Fig. 5A is a perspective view of another perspective of the air conditioner 100 shown in fig. 1A, in which the access door 120 is in an open state, and fig. 5B is a top view of the air conditioner 100 shown in fig. 5A. Fig. 5A and 5B show a state of the access door 120 during installation and removal.

Specifically, at the time of installing the access door 120, the operator first tilts the access door 120 to place the right flange 241 of the access door 120 in the accommodation space 316 between the hook portion 311 and the main body portion 313 of the holder 110. Then, the operator gradually rotates the access door 120 to be parallel to the access opening 109 and gradually pushes the access door 120 rightward until the hole 231 of the access door 120 is aligned with the screw hole 132 of the housing 101. In this process, the right turned edge 241 of the access door 120 gradually presses the body portion 313 of the holder 110, and the hook portion 311 of the holder 110 gradually presses the right turned edge 241 of the access door 120 toward the access opening 109. Finally, the operator uses the fasteners 130 through the holes 231 to mate with the threaded holes 132 to compress the left side of the access door 120, thereby completing the installation of the access door 120.

When needing to inspect and maintain the air conditioner 100, the operator only needs to remove the fastener 130 on the left side of the access door 120, and then inclines the left side of the access door 120 by a certain angle, so that the access door 120 can be detached from the access opening.

In the process of installing and detaching the access door 120, since the right side of the access door 120 is held by the holder 110, the operator only needs to screw two bolts for fixing the left side of the access door 120 and does not need to apply force by hand to prevent the access door 120 from falling from the access opening 109, so that the installation and detachment operations are convenient. The mounting structure of access door 120 of this application is particularly useful to concealed box air conditioner for the furred ceiling because this kind of air conditioner is located the furred ceiling, and operating personnel only has very little operating space on the one hand, and sight when operating on the one hand is also limited, adopts the mounting structure of access door 120 of this application after, operating personnel can fix a position access door 120 very easily to can realize installation and dismantlement fast.

In this embodiment, the fastener 130 is a butterfly bolt, and an operator can install and detach the butterfly bolt only by hand without using an additional operating tool, thereby significantly reducing the work difficulty of the operator.

It should be noted that although the holding member 110 of the present application is a whole extending along the height H of the housing 101, those skilled in the art will understand that in other embodiments, the holding member 110 may be divided into several holding members to achieve the same effect. In other embodiments, the holder 110 may also be disposed on the upper, lower, or left side of the service opening 109, and is not limited to the right side in this embodiment. Further, the access door 120 may not be provided with any burring, but a pressing force may be applied to the access door 120 by extending the tip of the hook portion 311 against the outer surface of the access door 120 to press the access door 120.

Although the present application will be described with reference to the particular embodiments shown in the drawings, it should be understood that many variations of the air conditioner of the present application are possible without departing from the spirit and scope and background of the teachings of the present application. Those of ordinary skill in the art will also realize that there are different ways of varying the details of the structures in the embodiments disclosed in this application that fall within the spirit and scope of the application and the claims.
