DETAILED DESCRIPTION OF EMBODIMENTS

[0022] Embodiments of the present invention will be described below in detail, and examples of the embodiments are illustrated in the accompanying drawings, where the same or similar reference numerals throughout the specification refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention rather than limit the present invention.

[0023] A housing assembly 100 of an air conditioner, and an air conditioner according to embodiments of the present invention will be described below with reference to FIGS. 1-6.

[0024] As shown in FIGS. 1-6, the housing assembly 100 of the air conditioner according to embodiments of the present invention includes: a face frame 1, a panel 2, and a chassis 3.

[0025] Specifically, as shown in FIGS. 4-5, the chassis 3 has an opening 21, the face frame 1 is coupled to the chassis 3 and coupled to the panel 2, and the panel 2 is arranged on a side of the face frame 1. The face frame 1 has a first sealing part 4, the panel 2 has a second sealing part 5, and the chassis 3 has a third sealing part 6 and a fourth sealing part 7 spaced apart from each other.

[0026] The fourth sealing part 7 is located at an edge of the opening 21 of the chassis 3. An airflow inside the air conditioner can flow out through the opening 21. As shown in FIG. 5, the first sealing part 4 of the face frame 1 is in contact with the third sealing part 6 of the chassis 3 to form a first sealing structure. The second sealing part 5 of the face frame 2 is in contact with the fourth sealing part 7 of the chassis 3 to form a second sealing structure. As a result, a double sealing structure can be formed on the chassis 3.

[0027] In the related art, when the air conditioner is in a cooling mode, cold air in an indoor environment can enter an interior of the housing assembly through a gap at the opening, and the temperature of air inside the housing is low while the indoor ambient temperature is high, so that condensate water is easily generated when hot and cold air streams meet.

[0028] For the housing assembly 100 according to the embodiments of the present invention, the first sealing structure is formed by the contact between the first sealing part 4 of the face frame 1 and the second sealing part 5 of the chassis 3, and the second sealing structure is formed by the contact between the second sealing part 5 of the panel 2 and the fourth sealing part 7 of the chassis 3. Such a double sealing structure can block the airflow in the indoor environment from entering the interior of the housing assembly 100, and can reduce the risk of generating condensation at the opening 21.

[0029] According to some embodiments of the present invention, as shown in FIG. 5, one of the first sealing part 4 and the third sealing part 6 includes a first groove 8, and the other of the first sealing part 4 and the third sealing part 6 includes a first protrusion 9. It can be understood that the third sealing part 6 may include the first protrusion 9 when the first sealing part 4 includes the first groove 8; alternatively, the first sealing part 4 may include the first protrusion 9 when the third sealing part 6 includes the first groove 8.

[0030] For example, as shown in FIG. 5, the first sealing part 4 includes the first groove 8 and the third sealing part 6 includes the first protrusion 9. In addition, it should be noted that the first groove 8 and the first protrusion 9 may be mutually embedded structures, and the first groove 8 and the first protrusion 9 have complementary shapes, to improve the sealing performance between the first sealing part 4 and the third sealing part 6. That is, the third sealing part 6 can be inserted into the first sealing part 4 to form a sealing structure. The sealing structure blocks the airflow in the indoor environment from entering an interior of the air conditioner, and can prevent hot and cold air from generating condensation at the opening 21.

[0031] Further, the first groove 8 may extend along the edge of the opening 21 of the chassis 3. Accordingly, the first protrusion 9 may also extend along the edge of the opening 21 of the chassis 3, so that a mating structure formed by the first groove 8 and the first protrusion 9 may extend along the edge of the opening 21, and the edge of the opening 21 can be effectively sealed. When the mating structure of the first groove 8 and the first protrusion 9 is arranged along a peripheral direction of the opening 21, the first groove 8 and the first protrusion 9 form an annular sealing structure, and the opening 21 can be sealed more effectively.

[0032] One of the second sealing part 5 and the fourth sealing part 7 includes a second groove 10, and the other of the second sealing part 5 and the fourth sealing part 7 includes a second protrusion 11. It can be understood that the fourth sealing part 7 may include the second protrusion 11 when the second sealing part 5 includes the second groove 10; alternatively, the second sealing part 5 may include the second protrusion 11 when the fourth sealing part 7 includes the second groove 10.

[0033] For example, as shown in FIG. 5, the second sealing part 5 includes the second groove 10, and the fourth sealing part 7 includes the second protrusion 11. In addition, it should be noted that the second groove 10 and the second protrusion 11 may be mutually embedded structures, and the second groove 10 and the second protrusion 11 have complementary shapes, to improve the sealing performance between the second sealing part 5 and the fourth sealing part 7. That is, the fourth sealing part 7 can be inserted into the second sealing part 5 to form a sealing structure. The sealing structure blocks the airflow in the indoor environment from entering the interior of the air conditioner, and can prevent hot and cold air from generating condensation at the opening 21.

[0034] Further, the second groove 10 may be formed by bending a partial edge of the panel 2. After the edge of the panel 2 is bent, a bent portion forms the second groove 10, simplifying a manufacturing process of the panel 2 and shortening a processing cycle of the panel 2.

[0035] According to some embodiments of the present invention, as shown in FIG. 5, a partial edge of the panel 2 is bent to form a bend, and the bend and an edge of the face frame 1 are fit to define the second groove 10. It can be understood that a lower edge of the face frame 1 provides a groove surface for the second groove 10, and the lower edge of the face frame 1 and the bend of the edge of the panel 2 define the second groove 10. With the groove and protrusion structures, the fourth sealing part 7 can be inserted into the second sealing part 5 to form a sealing structure. The sealing structure blocks fresh air from entering the interior of the air conditioner and avoids condensation since hot fresh air meets cold air inside the air conditioner.

[0036] According to some other embodiments of the present invention, as shown in FIGS. 4 and 6, the chassis 3 includes a first corner plate 12 and a second corner plate 13. The first corner plate 12 has a first main body segment 17 and a first thinned segment 18 coupled to the first main body segment 17. A ratio of a thickness of the first thinned segment 18 to a thickness of the first main body segment 17 ranges from 0.5 to 0.9. As shown in FIGS. 4 and 6, the second corner plate 13 has a first main body segment 19 and a second thinned segment 20 coupled to the first main body segment 19. A ratio of a thickness of the second thinned segment 20 to a thickness of the first main body segment 19 ranges from 0.5 to 0.9. As shown in FIG. 6, the first thinned segment 18 and the second thinned segment 20 are coupled and form an angle structure, and the first main body segment 17 and the first main body segment 19 are opposite each other and spaced apart.

[0037] When the air conditioner is in the cooling mode, the first corner plate 12 has a low temperature since the first corner plate 12 is close to an air outlet duct, and may be called a cold corner plate. The second corner plate 13 has a temperature approximate to the indoor ambient temperature since it is far away from the air outlet duct, and may be called a hot corner plate. When a distance between the cold corner plate and the hot corner plate is short, condensate water may be easily generated due to the cross between hot and cold environments. By arranging a thinned structure at a connection position of the cold corner plate and the hot corner plate, the distance between the first corner plate 12 and the second corner plate 13 can be increased to provide space for temperature homogenization of the air around the cold comer plate and the hot corner plate, avoiding the condensate water at the connection position of the first corner plate 12 and the second corner plate 13. By arranging the first thinned segment 18 in the first corner plate 12 and arranging the second thinned segment 19 in the second corner plate 13, the amount of cold air carried by the first corner plate 12 and the amount of heat carried by the second corner plate 13 can be reduced, so that the amount of hot and cold airflow at the connection position of the first corner plate 12 and the second corner plate 13 can be effectively reduced, and thus the generation of condensate water can be reduced.

[0038] According to some embodiments of the present invention, as shown in FIGS. 3-4, the housing assembly 100 further includes an air guide plate 14 coupled to the face frame 1, and the air guide plate 14 is rotatable between a first position 15 and a second position 16. When the air guide plate 14 is in the first position 15, the air guide plate 14 closes the opening 21. When the air guide plate 14 is in the second position 16, the air guide plate 14 is located inside the face frame 1, overlaps the first corner plate 12, and opens the opening 21. Thus, the air output volume and air output direction can be adjusted by rotating the air guide plate 14, improving user experience.

[0039] In some embodiments, an outer surface of the air guide plate 14 may be an appearance surface of the air conditioner. It can be understood that when the air guide plate 14 is in the second position 16, the outer surface of the air guide plate 14 overlaps or adheres to the first corner plate 12; when the air guide plate 14 is in the first position 15, the air guide plate 14 closes the opening 21 and the outer surface of the air guide plate 14 serves as the appearance surface of the air conditioner.

[0040] The housing assembly 100 of the air conditioner according to embodiments of the present invention will be described in detail below with reference to FIGS. 1-6. It should be understood that the following description is merely exemplary illustration rather than specific limitation on the present invention.

[0041] As shown in FIGS. 1-6, the housing assembly 100 includes: a face frame 1, a panel 2, a chassis 3, and an air guide plate 14.

[0042] Specifically, the chassis 3 has an opening 21, and the opening 21 may be used as an air outlet of the air conditioner. The face frame 1 has a first sealing part 4, the panel 2 has a second sealing part 5, and the chassis 3 has a third sealing part 6 and a fourth sealing part 7 spaced apart from each other, the fourth sealing part 7 being located at an edge of the opening 21 of the chassis 3. The first sealing part 4, the second sealing part 5, the third sealing part 6, and the fourth sealing part 7 may be sealing parts designed to reduce the condensation phenomenon.

[0043] As shown in FIGS. 4-5, the face frame 1 is coupled to the chassis 3. The first sealing part 4 of the face frame 1 is in contact with the third sealing part 6 of the chassis 3 to form a first sealing structure. As shown in FIGS. 4-5, the face frame 1 is coupled to the panel 2, and the panel 2 is arranged on a side of the face frame 1. In such a case, the second sealing part 5 of the panel 2 is in contact with the fourth sealing part 7 of the chassis 3 to form a second sealing structure. Such a double sealing structure can block the airflow in the indoor environment from entering the interior of the housing assembly 100, and can reduce the risk of generating condensation at the opening 21.

[0044] The face frame 1 is also coupled to the air guide plate 14 as shown in FIGS. 3-4. The air guide plate 14 is rotatable between a first position 15 and a second position 16. When the air guide plate 14 is in the first position 15, the air guide plate 14 closes the opening 21 of the chassis 3; when the air guide plate 14 is in the second position 16, the air guide plate 14 overlaps the first corner plate 12 and opens the opening 21 of the chassis 3. The air output volume and air output direction can be adjusted by rotating the air guide plate 14, bringing about better user experience.

[0045] As shown in FIG. 5, the first sealing part 4 includes a first groove 8, and the third sealing part 6 includes a first protrusion 9. The first groove 8 extends along the edge of the opening 21 of the chassis 3. As shown in FIG. 5, two surfaces of the first groove 8 and the first protrusion 9 are fitted with each other, and the first groove 8 and the first protrusion 9 are complementary in shape. As a result, the third sealing part 6 can be inserted into the first sealing part 4 to form a sealing structure. The sealing structure blocks fresh air from entering the interior of the air conditioner and avoids condensation since hot fresh air meets cold air inside the air conditioner.

[0046] As shown in FIG. 5, the second sealing part 5 includes a second groove 10, and the third sealing part 6 includes a second protrusion 11. The second groove 10 is formed by bending a partial edge of the panel 2. The second groove 10 extends along the edge of the opening 21 of the chassis 3. As shown in FIG. 5, surfaces of the second groove 10 and the second protrusion 11 are fitted with each other, and the second groove 10 and the second protrusion 11 are complementary in shape. Thus, the fit between the second groove 10 and the second protrusion 11 achieved by the complementary shape improves the sealing performance of the sealing structure.

[0047] As shown in FIG. 5, a lower edge of the face frame 1 provides a groove surface for the second groove 10, such that the lower edge of the face frame 1 and a bent edge of the panel 2 define the second groove 10. With the groove and protrusion structures, the fourth sealing part 7 can be inserted into the second sealing part 5 to form a sealing structure. The sealing structure blocks fresh air from entering the interior of the air conditioner and avoids condensation since hot fresh air meets cold air inside the air conditioner.

[0048] As shown in FIGS. 4 and 6, the chassis 3 includes a first corner plate 12 and a second corner plate 13. The first corner plate 12 has a first main body segment 17 and a first thinned segment 18 coupled to the first main body segment 17. A ratio of a thickness of the first thinned segment 18 to a thickness of the first main body segment 17 ranges from 0.5 to 0.9. As shown in FIGS. 4 and 6, the second corner plate 13 has a first main body segment 19 and a second thinned segment 20 coupled to the first main body segment 19. A ratio of a thickness of the second thinned segment 20 to a thickness of the first main body segment 19 ranges from 0.5 to 0.9. As shown in FIG. 6, the first thinned segment 18 and the second thinned segment 20 are coupled and form an angle structure, and the first main body segment 17 and the first main body segment 19 are opposite each other and spaced apart.

[0049] When the air conditioner is in the cooling mode, the first corner plate 12 has a low temperature since the first corner plate 12 is close to an air outlet duct, and may be called a cold corner plate. The second corner plate 13 has a temperature approximate to the indoor ambient temperature since it is far away from the air outlet duct, and may be called a hot corner plate. When a distance between the cold corner plate and the hot corner plate is short, condensate water may be easily generated due to the cross between hot and cold environments. By arranging a thinned structure at a connection position of the cold corner plate and the hot corner plate, the distance between the first corner plate 12 and the second corner plate 13 can be increased to provide space for temperature homogenization of the air around the cold comer plate and the hot corner plate, avoiding the condensate water at the connection position of the first corner plate 12 and the second corner plate 13. By arranging the first thinned segment 18 in the first corner plate 12 and arranging the second thinned segment 19 in the second corner plate 13, the amount of cold air carried by the first corner plate 12 and the amount of heat carried by the second corner plate 13 can be reduced, so that the amount of hot and cold airflow at the connection position of the first corner plate 12 and the second corner plate 13 can be effectively reduced, and thus the generation of condensate water can be reduced.

[0050] As shown in FIGS. 2-3, an air conditioner according to embodiments of the present invention includes the housing assembly 100 described above.

[0051] For the air conditioner according to embodiments of the present invention, the first sealing structure is formed by the contact between the first sealing part 4 of the face frame 1 and the second sealing part 5 of the chassis 3, and the second sealing structure is formed by the contact between the second sealing part 5 of the panel 2 and the fourth sealing part 7 of the chassis 3. Such a double sealing structure can block the airflow in the indoor environment from entering the interior of the housing assembly 100, and can reduce the risk of generating condensation at the opening 21.
