DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limit, the present disclosure.

[0026] An outdoor unit 100 according to embodiments of the present disclosure is described below with reference to FIG. 1 to FIG. 8.

[0027] As illustrated in FIG. 1 to FIG. 5, the outdoor unit 100 according to embodiments of the present disclosure in a first aspect includes an outdoor unit housing 1, a compressor assembly 2, an outdoor fan 3, an outdoor heat exchanger 4, an electrical control module assembly, and a mounting structure 6. The outdoor unit housing 1, the compressor assembly 2, the outdoor fan 3, the outdoor heat exchanger 4, and the electrical control module assembly are each disposed in the outdoor unit housing 1, and the mounting structure 6 is disposed at the outdoor unit housing 1.

[0028] The outdoor unit housing 1 has an electrical control chamber 11. For example, the outdoor unit housing 1 has the electrical control chamber 11 and a fan chamber that are arranged in a left-right direction. The electrical control chamber 11 is located at a right side of the fan chamber for accommodating the electrical control module assembly, etc. A wall of the outdoor unit housing 1 enclosing the electrical control chamber 11 is an electrical control chamber wall 12. The electrical control chamber wall 12 has a mounting hole structure 121 extending through the electrical control chamber wall 12 in a thickness direction of the electrical control chamber wall 12.

[0029] The compressor assembly 2 includes a compressor configured to compress and drive a refrigerant in a refrigerant circulation loop. Each of the compressor and the outdoor heat exchanger 4 is connected in series in the refrigerant circulation loop of the outdoor unit 100. The outdoor fan 3 is configured to drive outdoor air into the outdoor unit housing 1 through an air inlet 17 on the outdoor unit housing 1. The outdoor air exchanges heat with a heat exchanger of the outdoor unit 100 and is discharged to the outside of the outdoor unit housing 1 through an air outlet 18 on the outdoor unit housing 1 after heat exchange. The electrical control module assembly is disposed in the electrical control chamber 11 and configured to control operation of components such as the compressor assembly 2 and the outdoor fan 3 in the outdoor unit housing 1.

[0030] The mounting structure 6 is configured to mount and fix a temperature sensor. For example, the temperature sensor is configured to measure a temperature of ambient external environment of the outdoor unit 100. The mounting structure 6 includes a fixing structure 61 and a shielding plate 62. The fixing structure 61 is configured to fix the temperature sensor. The fixing structure 61 is engaged with the mounting hole structure 121 to fix the fixing structure 61 to the outdoor unit housing 1. When the shielding plate 62 is mounted at the outdoor unit housing 1, the shielding plate 62 at least partially faces towards the mounting hole structure 121 to shield at least part of the mounting hole structure 121. For example, the entire shielding plate 62 faces towards the mounting hole structure 121 and shields the entire mounting hole structure 121. For example, part of the shielding plate 62 faces towards the mounting hole structure 121 and configured to shield the entire mounting hole structure 121. For example, the entire shielding plate 62 faces towards the mounting hole structure 121 and shields part of the mounting hole structure 121. For example, the part of the shielding plate 62 faces towards the mounting hole structure 121 and is configured to shield the part of the mounting hole structure 121.

[0031] By disposing the fixing structure 61, the fixing structure 61 can be mounted and fixed at the outdoor unit housing 1 through engagement between the fixing structure 61 and the mounting hole structure 121. By setting the shielding plate 62, after the shielding plate 62 is mounted at the outdoor unit housing 1, the shielding plate 62 may at least be configured to shield the mounting hole structure 121, which can prevent or reduce an adverse effect on the electrical control module assembly in the electrical control chamber 11 caused by the rainwater, snowmelt and other moisture outside the outdoor unit housing 1 entering the electrical control chamber 11 through the mounting hole structure 121, and a resulting failure of the outdoor unit 100.

[0032] As illustrated in FIG. 1 to FIG. 5, the fixing structure 61 includes a fixing clip 611 and a fixing plate 612 connected to the fixing clip 611. The fixing clip 611 is configured to fix the temperature sensor, and the fixing plate 612 is configured to mount and fix the mounting structure 6 to the outdoor unit housing 1. The fixing plate 612 is provided with an engagement structure 613 configured to be engaged with the mounting hole structure 121. The engagement structure 613 corresponds to the mounting hole structure 121 formed at the electrical control chamber wall 12. Through the engagement between the engagement structure 613 and the mounting hole structure 121, the fixing structure 61 is fixed to the outdoor unit housing 1. By disposing the fixing plate 612 with the engagement structure 613, the fixing structure 61 can be mounted and fixed to the outdoor unit housing 1 through the engagement between the engagement structure 613 and the mounting hole structure 121.

[0033] With the outdoor unit 100 according to embodiments of the present disclosure, by disposing the mounting structure 6 with the shielding plate 62, when the mounting structure 6 is fixed to the outdoor unit housing 1 through the engagement with the mounting hole structure 121, the shielding plate 62 at least partially faces towards the mounting hole structure 121 to shield the mounting hole structure 121. In this way, the rainwater, snowmelt and other moisture can be reduced or prevented from entering the electrical control chamber 11 through the mounting hole structure 121 at the outdoor unit housing 1, which avoids the adverse effect on an electrical device such as the electrical control module assembly, preventing the failure of the outdoor unit 100.

[0034] According to some embodiments of the present disclosure, as illustrated in FIG. 2, and FIG. 6 to FIG. 8, when the fixing structure 61 is mounted and fixed to the outdoor unit housing 1 through the engagement between the engagement structure 613 on the fixing plate 612 and the mounting hole structure, and when the shielding plate 62 is also mounted and fixed to the outdoor unit housing 1, the shielding plate 62 is located at a side of the fixing plate 612 away from the mounting hole structure 121 and covers the fixing plate 612. By disposing the shielding plate 62 at the side of the fixing plate 612 away from the mounting hole structure 121, and by allowing the shielding plate 62 to cover the fixing plate 612, after the fixing plate 612 is fixed to the outdoor unit housing 1 through the engagement structure 613 and the mounting hole structure 121, a covering effect of the shielding plate 62 on the fixing plate 612 can reduce or prevent the rainwater, snowmelt and other moisture from flowing from the side of the fixing plate 612 away from the mounting hole structure 121 to the mounting hole structure 121 through the fixing plate 612 and then entering the electrical control chamber 11 from the mounting hole structure 121 through the electrical control chamber wall 12. Therefore, the adverse effect on the electrical device such as the electrical control module assembly caused by the water entering the electrical control chamber 11 from the mounting hole structure 121 and the resulting failure of the outdoor unit 100 are avoided or reduced.

[0035] According to some optional embodiments of the present disclosure, as illustrated in FIG. 2, and FIG. 6 to FIG. 8, when the fixing structure 61 is mounted and fixed to the outdoor unit housing 1 through the engagement between the engagement structure 613 on the fixing plate 612 and the mounting hole structure, and when the shielding plate 62 is also mounted and fixed to the outdoor unit housing 1, a projection of the fixing plate 612 on the shielding plate 62 is entirely located in the shielding plate 62. By enabling the projection of the fixing plate 612 on the shielding plate 62 to be entirely located in the shielding plate 62, the fixing plate 612 can be completely covered by the shielding plate 62, which can better prevent the water and the like from penetrating into a space between the shielding plate 62 and the fixing plate 612 from a periphery of the shielding plate 62 and then entering the outdoor unit housing 1 through the fixing plate 612 and the mounting hole structure 121. Therefore, the adverse effect on the electrical device such as the electrical control module assembly caused by the water and the like entering the electrical control chamber 11 through the mounting hole structure 121 can be more effectively avoided, in such a manner that the resulting failure of the outdoor unit 100 can be more effectively avoided.

[0036] According to some optional embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, the shielding plate 62 has an avoidance groove structure 621 formed at a side of the shielding plate 62 facing towards the fixing plate 612, and the avoidance groove structure 621 is configured to avoid the engagement structure 613. When the fixing structure 61 is mounted and fixed to the outdoor unit housing 1 through the engagement between the engagement structure 613 on the fixing plate 612 and the mounting hole structure, and when the shielding plate 62 is also mounted and fixed to the outdoor unit housing 1, the engagement structure 613 can be accommodated in the avoidance groove structure 621, preventing interference between the engagement structure 613 and the shielding plate 62 affecting the covering effect of the shielding plate 62 on the fixing plate 612. The avoidance groove structure 621 may not go through the shielding plate 62, which can avoid formation of a through structure on the shielding plate 62, affecting effects of the shielding plate 62 in covering the fixing plate 612 and shielding the mounting hole structure 121.

[0037] According to some optional embodiments of the present disclosure, as illustrated in FIG. 3 to FIG. 8, the engagement structure 613 includes a first snap 6131 configured to form a snap-fit relationship between the engagement structure 613 and the mounting hole structure 121. The mounting hole structure 121 has a first snap hole 1211 corresponding to the first snap 6131 and configured to form the snap-fit relationship between the mounting hole structure 121 and the engagement structure 613. The first snap 6131 is engaged with the first snap hole 1211 to form the snap-fit relationship between the engagement structure 613 and the mounting hole structure 121. Therefore, the fixing plate 612 is engaged into the electrical control wall through the engagement structure 613, and the fixing structure 61 is engaged into the outdoor unit housing 1 through the engagement structure 613. The avoidance groove structure 621 has a first avoidance groove 6211 configured to avoid the first snap 6131. After the fixing structure 61 is engaged into the mounting hole structure 121 through the first snap 6131, and the shielding plate 62 is also fixed to the outdoor unit housing 1, a structure of the first snap 6131 located at a side of the fixing plate 612 facing towards the shielding plate 62 can be accommodated in the first avoidance groove 6211.

[0038] By disposing the first snap 6131 and the first snap hole 1211, the snap-fit relationship is formed between the engagement structure 613 of the fixing plate 612 and the mounting hole structure 121 through the engagement between the first snap 6131 and the first snap hole 1211, which simplifies the engagement between the fixing plate 612 and the mounting hole structure 121, facilitating disassembly and assembly of the fixing plate 612 relative to the mounting hole structure 121. By setting the first avoidance groove 6211, interference between the shielding plate 62 and the first snap 6131 structure is prevented from affecting the covering effect of the shielding plate 62 on the fixing plate 612.

[0039] According to some optional embodiments of the present disclosure, as illustrated in FIG. 3 to FIG. 8, the engagement structure 613 includes a fastener and a first fixing hole 614 disposed at the fixing plate 612, and the mounting hole structure 121 has a second fixing hole 1212. The fastener passes through the first fixing hole 614 and the second fixing hole 1212, to form a fixed connection relationship between the engagement structure 613 and the mounting hole structure 121, fixedly connecting the fixing plate 612 to the electrical control wall of the outdoor unit housing 1 through the fastener. The avoidance groove structure 621 has a second avoidance groove 6212 configured to avoid the fastener. After the fixing structure 61 is fixed to the mounting hole structure 121 by allowing the fastener to pass through the first fixing hole 614 and the second fixing hole 1212, and the shielding plate 62 is also fixed to the outdoor unit housing 1, part of the fastener located at the side of the fixing plate 612 away from the mounting hole structure 121 can be accommodated in the second avoidance groove 6212.

[0040] By disposing the fastener, the first fixing hole 614, and the second fixing hole 1212, and by allowing the fastener to pass through the first fixing hole 614 and the second fixing hole 1212, the fixing plate 612 is fixedly connected to the electrical control wall forming the mounting hole structure 121. Therefore, this connection relationship is simple and mounting operation is convenient. In addition, stability of the engagement between the fixing plate 612 and the mounting hole structure 121 can be improved through connection of the fastener. By disposing the second avoidance groove 6212, interference between the shielding plate 62 and the fastener is avoided, preventing affecting the covering effect of the shielding plate 62 on the fixing plate 612.

[0041] According to some optional embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, one of the shielding plate 62 and the fixing plate 612 is provided with a second snap 6121, and the other one of the shielding plate 62 and the fixing plate 612 has a second snap hole 622. When the fixing plate 612 is covered by the shielding plate 62, the second snap 6121 is engaged into the second snap hole 622. For example, the second snap 6121 is disposed at the shielding plate 62, and the second snap hole 622 that may be engaged with the second snap 6121 is disposed at the fixing plate 612. For example, the second snap hole 622 is disposed at the shielding plate 62, and the second snap 6121 that may be engaged into the second snap hole 622 is disposed at the fixing plate 612. By disposing the second snap 6121 and the second snap hole 622, and by allowing the second snap 6121 to be engaged into the second snap hole 622, the shielding plate 62 can be engaged into the fixing plate 612. Therefore, an engaging structure between the shielding plate 62 and the fixing plate 612 is simple and can enable the shielding plate 62 to stably cover the fixing plate 612.

[0042] According to some optional embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, the second snap hole 622 is formed at the shielding plate 62, and the second snap 6121 is disposed at an outer edge of the fixing plate 612. By disposing the second snap 6121 at the outer edge of the fixing plate 612, the second snap hole 622 corresponding to the second snap 6121 may also be disposed close to an edge of the fixing plate 612. When the fixing plate 612 is covered by the shielding plate 62, the second snap hole 622 is positioned away from the engagement structure 613, which can minimize the influence of the second snap hole 622 on the covering effect of the shielding plate 62 on the fixing plate 612. Therefore, the shielding plate 62 can effectively prevent the rainwater, snowmelt and other moisture from flowing from the side of the fixing plate 612 away from the mounting hole structure 121 to the mounting hole structure 121 through the fixing plate 612 and then entering the electrical control chamber 11 from the mounting hole structure 121 through the electrical control chamber wall 12, avoiding the water and the like from adversely affecting the electrical device such as the electrical control module assembly in the electrical control chamber 11. In this way, the resulting failure of the outdoor unit 100 can be avoided.

[0043] According to some optional embodiments of the present disclosure, as illustrated in FIG. 2, and FIG. 6 to FIG. 8, the shielding plate 62 is connected to the fixing plate 612. In this way, the mounting structure 6 can be integrated into a whole for convenient mounting. Also, the mounting structure 6 can be integrally fixed to the outdoor unit housing 1 through an engagement relationship between the engagement structure 613 of the fixing plate 612 and the mounting hole structure 121. The shielding plate 62 is foldable between an unfolded position and a folded position. By folding the shielding plate 62 from the unfolded position to the folded position, the fixing plate 612 is covered by the shielding plate 62. When the shielding plate 62 is in the unfolded position, the fixing plate 612 is not covered by the shielding plate 62. In addition, the shielding plate 62 is located at an outer peripheral side of the fixing plate 612 and is spaced apart from the fixing clip 611 in a peripheral direction of the fixing plate 612. For example, when the shielding plate 62 is in the unfolded position, the shielding plate 62 is located at a side of the fixing plate 612 away from the fixing clip 611. When the shielding plate is in the folded position, the shielding plate 62 is located at a side of the fixing plate 612 away from the mounting hole structure 121 and covers the fixing plate 612.

[0044] By connecting the shielding plate 62 to the fixing plate 612 and making the shielding plate 62 foldable between the unfolded position and the folded position, a foldable structure allows the shielding plate 62 to easily cover the fixing plate 612, shielding the mounting hole structure 121. In addition, when the shielding plate 62 is in the unfolded position, connection and observation of the engagement relationship between the engagement structure 613 of the fixing plate 612 and the mounting hole structure 121 are facilitated, to ensure that the fixing plate 612 is stably connected to the mounting hole structure 121. When the shielding plate 62 is in the folded position, the shielding plate 62 can cover the fixing plate 612, which can prevent the rainwater, snowmelt and other moisture from flowing from the side of the fixing plate 612 away from the mounting hole structure 121 to the mounting hole structure 121 through the fixing plate 612 and then entering the electrical control chamber 11 from the mounting hole structure 121 through the electrical control chamber wall 12, avoiding the adverse effect on the electrical device such as the electrical control module assembly in the electrical control chamber 11 caused by the water and the like entering the electrical control chamber 11 through the mounting hole structure 121. In this way, the resulting failure of the outdoor unit 100 can be avoided.

[0045] According to some optional embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, the shielding plate 62 is connected to the fixing plate 612 through a first flexible portion 63 that is bendable. Disposing the first flexible portion 63 facilitates folding of the shielding plate 62 between the unfolded position and the folded position.

[0046] According to some embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, the fixing clip 611 defines an accommodation cavity, and the temperature sensor is mounted in the accommodation cavity. By defining the accommodation cavity in the fixing clip 611, the temperature sensor can be mounted in the fixing clip 611 by being accommodated in the cavity, in such a manner that the temperature sensor can be mounted to the mounting structure 6 and fixedly mounted to the outdoor unit housing 1 through the engagement relationship between the engagement structure 613 of the fixing plate 612 and the mounting hole structure 121.

[0047] According to some optional embodiments of the present disclosure, as illustrated in FIG. 6 to FIG. 8, the fixing clip 611 includes a fixing portion 6111 and a covering portion 6112 connected to the fixing portion 6111. The fixing portion 6111 is connected between the fixing plate 612 and the covering portion 6112. The covering portion 6112 is foldable relative to the fixing portion 6111 between a folded position and an unfolded position. When the covering portion 6112 is in the folded position, an accommodation cavity is defined between the covering portion 6112 and the fixing portion 6111. When the covering portion 6112 is in the unfolded position, the covering portion 6112 exposes the accommodation cavity, and the temperature sensor is mounted in the accommodation cavity. By disposing the fixing portion 6111 and the covering portion 6112 connected to the fixing portion 6111, and making the covering portion 6112 foldable relative to the fixing portion 6111 between the folded position and the unfolded position, the covering portion 6112 can switch between the folded position and the unfolded position in a simple manner, and the foldable structure allows the covering portion 6112 to easily cover the fixing portion 6111. In addition, when the covering portion 6112 is in the unfolded position, the temperature sensor can be taken out of or placed into the accommodation cavity.
