Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] When the air conditioner is running, airflow enters the indoor unit, exchanges heat with the heat exchanger, and then the resulting airflow is blown out. The heat exchanger has end plates on both sides, flush with the end plates. The top and bottom ends of the end plates form outward-facing flanges away from the heat exchanger. The heat exchanger is secured to the housing with screws. However, securing the heat exchanger solely with screws in the top and bottom directions is unreliable. Especially during transportation, if the indoor unit is dropped, the heat exchanger may shake significantly inside, potentially causing collisions and resulting in the heat exchanger fins bending.

Multiple grounding points are provided in the heat exchanger 20, so that if one grounding wire fails, the other grounding wires can continue to function, maintaining the stable operation of the indoor unit 100 of the air conditioner. Furthermore, the multiple grounding points more effectively disperse and guide current, improving the safety performance of the indoor unit 100 of the air conditioner.

[0083] In some embodiments of this utility model, such as Figures 4 to 6 As shown, the second end portion 120 has a plurality of first protruding ribs 123 and a plurality of second protruding ribs 124. The first protruding ribs 123 extend along the length direction of the first side plate 211, and the second protruding ribs 124 extend along the length direction of the first side plate 211. The first protruding ribs 123 contact and abut with the end portion of the first side plate 211. The second protruding ribs 124 contact and abut with the end portion of the second side plate 221.

[0084] In this embodiment, the second end plate 120 has a first protruding rib 123 and a second protruding rib 124. The first protruding rib 123 contacts and abuts against the end of the first side plate 211, and the second protruding rib 124 contacts and abuts against the end of the second side plate 221. After the heat exchanger 20 is installed, the first protruding rib 123 supports the first side plate 211, and the second protruding rib 124 supports the second side plate 221. The first protruding rib 123 and the second protruding rib 124 enhance the compressive strength of the second end plate, thereby improving the structural stability of the second end plate, making the heat exchanger 20 more securely fixed and reducing the risk of damage to the heat exchanger 20.

[0085] In some embodiments of this utility model, such as Figure 5 As shown, a fourth flange 218 is provided at one end of the first side plate 211, which contacts and abuts against the first protruding rib 123. The fourth flange 218 is located on the side of the first side plate 211 away from the heat exchange section 230.

[0086] In this embodiment, a fourth flange 218 is also provided on the first side plate 211, and the first protruding rib 123 abuts against the fourth flange 218. The fourth flange 218 is perpendicular to the first side plate 211, which makes the structure at the abutment of the first side plate 211 and the first protruding rib 123 more stable, improves the load-bearing capacity of the first side plate 211, and thus improves the firmness of the heat exchanger 20.

[0087] In some embodiments of this utility model, a fifth flange is provided at one end of the second side plate 221, which contacts and abuts against the second protruding rib 124. The fifth flange is located on the side of the second side plate 221 away from the heat exchange part 230.

[0088] In this embodiment, a fifth flange is also provided on the second side plate 221, and the second protruding rib 124 abuts against the fifth flange. The fifth flange is perpendicular to the second side plate 221, which makes the structure at the abutment point between the second side plate 221 and the second protruding rib 124 more stable, improves the load-bearing capacity of the second side plate 221, and thus improves the firmness of the heat exchanger 20.

[0089] In some preferred embodiments of this utility model, a fourth flange 218 is provided at a corresponding end of the first side plate 211, which contacts and abuts against the first protruding rib 123. The fourth flange 218 is located on the side of the first side plate 211 away from the heat exchange part 230. A fifth flange is provided at a corresponding end of the second side plate 221, which contacts and abuts against the second protruding rib 124. The fifth flange is located on the side of the second side plate 221 away from the heat exchange part 230.

[0090] In some embodiments of this utility model, such as Figure 4 and Figure 7 and Figure 9As shown, the frame 10 is vertically arranged, and both the first side plate 211 and the second side plate 221 are vertically arranged. The first end 110 is located above the second end 120. The first end 110 forms an upward-opening water spray trough 114, and the bottom of the water spray trough 114 is provided with multiple water outlet holes 115 for supplying water to the heat exchanger 20. The second end 120 forms an upward-opening water receiving trough 125, and the lower end of the heat exchanger 20 is located in the water receiving trough 125.

[0091] In this embodiment, the frame 10 is vertically arranged, with the first end 110 located at the upper end of the frame 10 and the second end 120 located at the lower end of the frame 10. The first end 110 forms an upward-opening water spray trough 114. The second end 120 forms an upward-opening water receiving trough 125. When the air conditioner is running, the air exchanges heat with the heat exchanger 20, and the heat exchanger 20 condenses the moisture in the air into water, which flows downward along the heat exchanger 20. Therefore, the air blown out by the indoor unit 100 of the air conditioner is dry, which can easily cause discomfort to the user. Since the water spray trough 114 is provided above the heat exchanger 20, when the indoor unit 100 of the air conditioner is running, the water spray trough 114 is filled with water, and the water flows downward through the water outlet 115 at the bottom of the water spray trough 114 onto the heat exchanger 20. After the water evaporates on the heat exchanger 20, it is blown into the room with the airflow, increasing the humidity of the air exchanged, avoiding an overly dry indoor environment, and improving the user experience.

[0092] Furthermore, the water collection tank 125 collects the water flowing down from the heat exchanger 20, preventing water from splashing inside the air conditioner indoor unit 100, avoiding the growth of bacteria, keeping the inside of the air conditioner indoor unit 100 clean, improving the air quality of the air conditioner indoor unit 100, and further enhancing the user experience.

[0093] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
