Description

Technical Field

[0001] This utility model relates to the field of washing machine drying, and in particular to a heat drying air outlet cover for washing machines. Background Technology

[0002] Nowadays, people's material needs are getting higher and higher, and the functions of various home appliances are becoming more diversified. Washing machines, for example, are no longer limited to washing functions. They also have functions such as timer, sterilization, and drying, which has led to the washer-dryer combos we are familiar with today.

[0003] Currently, washing machine dryers typically employ a built-in fan structure. Washing machines with this type of drying module are prone to fan clogging after a period of operation, especially at the impeller. Once the fan is clogged, the drying efficiency is reduced, and the washing machine itself poses a safety risk. Existing technology typically uses a filter at the fan outlet to prevent lint from contacting the impeller. However, this method often results in the filter being loosely installed or falling off due to airflow, failing to effectively solve the lint clogging problem and affecting the dryer's performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hot drying air hood for a washing machine, based on the current state of the technology.

[0010] Preferably, an elongated hole is provided between the connecting holes, and the shaft body covers the elongated hole.

[0011] Preferably, the cover is equipped with a swivel motor electrically connected to the flipping part. When hot air is emitted, the swivel motor drives the flipping plate to flip, and hot air is emitted from the air outlet. After the hot air is stopped, the swivel motor drives the flipping plate to flip back along the original path, and the flipping plate covers the air outlet.

[0012] Compared with the prior art, the advantages of this utility model are as follows: by setting a flip-up plate at the air outlet, when drying is required, hot air blows through the air outlet to rotate the flip-up plate, sending the hot air to the drying area where the clothes need to be dried.

Example 1

[0022] like Figures 1 to 3 As shown, this utility model provides a hot air outlet cover for a washing machine, including a cover body 1. At least one set of air outlet units are arranged in parallel on the cover body 1. Each set of air outlet units includes an air outlet part and a flipping part disposed on the cover body 1. The flipping part is rotatably disposed on the cover body 1. Specifically, when hot air is emitted, the hot air is emitted through the air outlet part, and at the same time, the hot air blows the flipping part to a certain angle with the air outlet part. When the hot air is stopped, the flipping part vertically covers the air outlet part under the action of gravity.

[0023] The cover 1 has a hollowed-out air outlet cavity for air outlet, and the air outlet unit is located on the air outlet cavity; specifically, the air outlet part includes at least one air outlet flap 2 arranged side by side on the air outlet cavity, and the air outlet flap 2 is evenly provided with a plurality of air outlets 3 for air outlet.

[0024] The two sides of the cover 1 are a fixing surface 4 for fixing to the washing machine and an air outlet surface 5 for air outlet; specifically, a number of fixing posts 6 are provided along the outer edge of the fixing surface 4, and the flipping part is rotatably disposed on the air outlet surface 5.

[0025] The flipping part includes a flipping plate 7. When the hot air stops, the flipping plate 7 covers the air outlet 3. The top of the flipping plate 7 is provided with a shaft 8 for flipping. Specifically, the top two sides of the air outlet flap 2 are respectively provided with connecting holes 9 that are hinged to the two ends of the shaft 8.

[0026] The shaft 8 is a long cylindrical shape, and the inner wall of the connecting hole 9 is a smooth arc. The inner wall of the connecting hole 9 and the outer edge of the shaft 8 are in contact and fit together. Specifically, the outer edges of both ends of the shaft 8 slide along the inner wall of the connecting hole 9, and the flip plate 7 drives the shaft 8 to rotate.

[0027] An elongated hole 10 is provided between the connecting holes 9, and the shaft 8 covers the elongated hole 10.

[0028] The working principle of this utility model is as follows: When the drying is stopped, the two ends of the shaft 8 are respectively inserted into the connecting holes 9, the shaft 8 covers the elongated hole 10, and the flip plate 7 vertically covers the air outlet flap 2 under its own gravity. The flip plate 7 covers the air outlet 3 to prevent lint and dust from entering the drying module through the air outlet 3 and clogging the fan.

[0029] In the drying state, the fan blows out hot air, which blows through the air outlet 3 onto the flip plate 7. Under the blowing of the hot air, the flip plate 7 flips outward to form a certain angle with the air outlet flap 2. The flip plate 7 drives the shaft 8 to rotate. The outer edges of both ends of the shaft 8 rotate along the smooth arc of the inner wall of the connecting hole 9. After the hot air passes through the air outlet 3, it blows open the flip plate 7 and finally delivers it to the drying area where the clothes need to be dried.

[0030] The advantages of this invention are as follows: By setting a flip-up plate 7 at the air outlet 3, when drying is required, hot air blows through the air outlet 3 to rotate the flip-up plate 7, delivering the hot air to the drying area where the clothes need to be dried. When the drying function is not needed, the flip-up plate 7 vertically covers the air outlet 3, effectively preventing tiny lint from entering the fan and avoiding lint from getting tangled in the fan impeller. As a result, the drying module has high safety and a long service life. Compared with the filter screen in the prior art, there is no risk of parts falling off, thus ensuring stable and reliable operation of the washing machine. Example 2

[0031] Unlike Embodiment 1, in this embodiment, the cover 1 is equipped with a swivel motor electrically connected to the flipping part. When hot air is emitted, the swivel motor drives the flipping plate 7 to flip, and hot air is emitted from the air outlet 3. After the hot air is stopped, the swivel motor drives the flipping plate 7 to flip back along the original path, and the flipping plate 7 covers the air outlet 3.

[0032] When hot air is needed, the tilting motor drives the flip plate 7 to open in advance, and then hot air is emitted from the air outlet 3. When not in use, the hot air is stopped first, and after a short delay, the tilting motor drives the flip plate 7 to flip and cover the air outlet 3. This serves to ensure safe heat dissipation and extend the service life of the drying module. Other structures are the same as in Example 1.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0034] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology, and will not be described in detail here.
