Description

Technical Field

[0001] This application relates to the field of dryer technology, and more specifically, to an internal circulation dryer. Background Technology

[0002] Clothes dryers are common appliances in modern households for quickly drying clothes. Currently, most clothes dryers on the market use a bottom-mounted hot air system design, meaning the core heating and air supply components, such as the fan and heating elements, are integrated at the bottom of the dryer. This traditional "bottom-mounted" design has two particularly prominent inherent drawbacks:

[0003] 1. Low thermal efficiency and uneven drying: Due to the low density of hot air, it has a natural tendency to rise. This design goes against this physical property, blowing hot air from the bottom upwards. This process results in low heat exchange efficiency between the hot air and the clothes, and easily leads to heat accumulation at the top of the chamber, causing a significant temperature difference between the top and bottom of the drying chamber and uneven heat distribution. This not only affects drying efficiency and uniformity but also causes additional energy waste.

[0004] 2. Serious safety hazards exist: When drying clothes with high moisture content, water droplets or condensation from the clothes may drip directly onto electrical components such as the fan and heating wires located at the bottom. This can easily cause short circuits, damage to components, and may even lead to electric shock, fire, and other safety risks, seriously threatening the life and property safety of users.

[0005] Therefore, those skilled in the art have been seeking a dryer technology solution that can fundamentally overcome the above-mentioned defects and achieve more efficient and safer drying. Utility Model Content

[0006] This application provides an internal circulation dryer, which can solve the problems of low heat energy utilization, uneven drying, and safety hazards in existing dryers.

[0007] To address the aforementioned technical problems, this application provides an internal circulation dryer, employing the following technical solution:

[0008] An internal circulation dryer includes a cabinet, a hot air blower, and a circulating fan;

[0009] The cabinet is equipped with a cover plate and a top plate, which are located on the top of the cabinet from top to bottom. A first receiving cavity and a second receiving cavity are formed between the cover plate and the top plate. The hot air fan is located in the first receiving cavity, and the circulating fan is located in the second receiving cavity.

[0010] The cabinet is also equipped with a partition, an air duct is formed between the partition and the right side wall of the cabinet, and a storage space is formed between the partition and the left side wall of the cabinet. The bottom of the partition is provided with a first ventilation hole. The first receiving cavity, the air duct, the first ventilation hole and the storage space are connected in sequence.

[0011] The top plate is provided with a second ventilation hole and a third ventilation hole, and the storage space, the second ventilation hole, the second accommodating cavity and the third ventilation hole are connected in sequence.

[0012] In some embodiments, the cabinet is further provided with a first cavity shell, such that a first receiving cavity is formed inside the first cavity shell and the first receiving cavity is in communication with the outside.

[0013] In some embodiments, the cover plate is provided with a fourth ventilation hole, which is connected to the first receiving cavity, so that the first receiving cavity is connected to the outside through the fourth ventilation hole.

[0014] In some embodiments, the first cavity shell is provided with a fifth ventilation hole, and the fourth ventilation hole and the fifth ventilation hole are sequentially connected to the first receiving cavity.

[0015] In some embodiments, a guide vane is provided on the first cavity shell, and the guide vane has an arc-shaped structure.

[0016] In some embodiments, the cabinet is further provided with a second cavity shell, such that the second receiving cavity is formed within the second cavity shell.

[0017] In some embodiments, the second cavity shell is provided with a first air baffle and a second air baffle, and the circulating fan is located between the first air baffle and the second air baffle.

[0018] In some embodiments, the cabinet is also provided with a sixth ventilation hole, which is connected to the storage space.

[0019] In some embodiments, the cabinet is also provided with a seventh ventilation hole, and the sixth and seventh ventilation holes are connected to the storage space in sequence.

[0020] In some embodiments, a cabinet door is also included, which is hinged to the cabinet body.

[0021] Compared with the prior art, the embodiments of this application have the following main advantages:

[0022] This internal circulation dryer includes a cabinet, a hot air blower, and a circulating fan. The cabinet has a cover and a top plate, which are positioned at the top of the cabinet from top to bottom, forming a first and a second receiving cavity. The hot air blower is located in the first receiving cavity, and the circulating fan is located in the second receiving cavity. The cabinet also has a partition, with an air duct formed between the partition and the right side wall of the cabinet, and a storage space formed between the partition and the left side wall of the cabinet. A first ventilation hole is provided at the bottom of the partition. The first receiving cavity, the air duct, the first ventilation hole, and the storage space are sequentially connected. The top plate has a second and a third ventilation hole, which are sequentially connected to the storage space, the second ventilation hole, the second receiving cavity, and the third ventilation hole. When using this internal circulation dryer, an external power source is connected, and the hot air blower is activated. The hot air blower and circulating fan, installed at the top of the cabinet, draw outside air into the first receiving cavity and heat it to obtain hot air. The hot air blower then delivers the hot air to the air duct. After being transported through the air duct, the hot air is delivered from the first receiving cavity at the top of the cabinet to the first ventilation hole at the bottom of the partition and enters the storage space. The circulating fan, driven by mechanical power, forces the hot air in the storage space to circulate, thereby achieving uniform temperature distribution and efficient heat energy utilization. In addition, the hot air blower and circulating fan are located at the top of the cabinet, which can prevent water droplets or condensation from clothes from dripping directly onto the hot air blower and circulating fan, eliminating safety hazards. This can solve the problems of low heat energy utilization, uneven drying, and safety hazards in existing dryers. Attached Figure Description

[0036] This application provides an internal circulation dryer, such as... Figures 1 to 6 As shown, it includes cabinet 1, hot air blower 2, circulating fan 3, and cabinet door 4;

[0037] The cabinet 1 is provided with a cover plate 11, a top plate 12, and a first cavity shell 13. The cover plate 11 and the top plate 12 are arranged from top to bottom on the top of the cabinet 1. The first cavity shell 13 is installed between the cover plate 11 and the top plate 12, so that a first receiving cavity is formed in the first cavity shell 13 between the cover plate 11 and the top plate 12 (that is, the first receiving cavity is formed in the first cavity shell 13), and the hot air blower 2 is installed in the first receiving cavity.

[0038] The cover plate 11 is provided with a fourth ventilation hole 111, and the first cavity shell 13 is provided with a fifth ventilation hole 131. The fourth ventilation hole 111 and the fifth ventilation hole 131 are sequentially connected to the first receiving cavity. In addition, the fourth ventilation hole 111 is connected to the outside, that is, the outside, the fourth ventilation hole 111, the fifth ventilation hole 131 and the first receiving cavity are sequentially connected. When the external power supply is connected and the hot air fan 2 is started, the hot air fan 2 installed on the top of the cabinet 1 draws outside air into the first receiving cavity through the fourth ventilation hole 111 and the fifth ventilation hole 131 in sequence and heats it to obtain hot air.

[0039] In this embodiment, the fourth ventilation hole 111 is an oblong shape. In other embodiments, the shape of the fourth ventilation hole 111 can be changed according to the actual situation. For example, the fourth ventilation hole 111 can be a square; or, the fourth ventilation hole 111 can be a circle; or, the fourth ventilation hole 111 can be an ellipse; or, the fourth ventilation hole 111 can be a triangle.

[0040] In this embodiment, the fifth ventilation hole 131 is rectangular. In other embodiments, the shape of the fifth ventilation hole 131 can be changed according to the actual situation. For example, the fifth ventilation hole 131 can be square; or, the fifth ventilation hole 131 can be circular; or, the fifth ventilation hole 131 can be elliptical; or, the fifth ventilation hole 131 can be triangular.

[0041] The cabinet 1 is also equipped with a partition 14. An air duct 101 is formed between the partition 14 and the right side wall of the cabinet 1, and a storage space 102 is formed between the partition 14 and the left side wall of the cabinet 1. A first ventilation hole 141 is provided at the bottom of the partition 14. The first receiving cavity, the air duct 101, the first ventilation hole 141, and the storage space 102 are connected in sequence. The hot air blower 2 delivers the obtained hot air from the first receiving cavity to the air duct 101. After being delivered by the air duct 101, the hot air is delivered from the first receiving cavity at the top of the cabinet 1 to the first ventilation hole 141 at the bottom of the partition 14 and then enters the storage space 102 (the direction of hot air flow is as follows). Figure 2 (As shown).

[0042] In this embodiment, the first ventilation hole 141 is shaped like a plum blossom. In other embodiments, the shape of the first ventilation hole 141 can be changed according to the actual situation. For example, the first ventilation hole 141 can all be square; or, the first ventilation hole 141 can all be round square; or, the first ventilation hole 141 can all be elliptical; or, the first ventilation hole 141 can all be triangular.

[0043] In addition, the first cavity shell 13 is provided with a guide vane 132, which has an arc-shaped structure, so that the hot air blower 2 can better transport the hot air obtained from the first receiving cavity to the air duct 101.

[0044] In this embodiment, the air duct 101 is vertically arranged from top to bottom, which allows hot air to be transported more smoothly from the first receiving cavity at the top of the cabinet 1 to the first ventilation hole 141 at the bottom of the partition 14 and then into the storage space 102. In other embodiments, the air duct 101 can be curved, as long as the hot air blower 2 transports the obtained hot air from the first receiving cavity to the air duct 101, and after being transported by the air duct 101, the hot air is transported from the first receiving cavity at the top of the cabinet 1 to the first ventilation hole 141 at the bottom of the partition 14 and then into the storage space 102.

[0045] The cabinet 1 is also provided with a second cavity shell 15, which is installed between the cover plate 11 and the top plate 12, so that a second receiving cavity is formed in the second cavity shell 15 between the cover plate 11 and the top plate 12 (that is, a second receiving cavity is formed between the cover plate 11 and the top plate 12, and the second receiving cavity is formed in the second cavity shell 15), and the circulating fan 3 is installed in the second receiving cavity.

[0046] The second cavity shell 15 is provided with a first air baffle 151 and a second air baffle 152. The circulating fan 3 is located between the first air baffle 151 and the second air baffle 152. The top plate 12 is provided with a second ventilation hole 121 and a third ventilation hole 122, so that the storage space 102, the second ventilation hole 121, the second accommodating cavity and the third ventilation hole 122 are connected in sequence. When an external power source is connected, the circulating fan 3 rotates the fan blades, converting electrical energy into mechanical energy. That is, the circulating fan 3 drives the airflow through mechanical power, forcibly circulating the hot air in the storage space 102 (the direction of hot air flow is as follows). Figure 2 As shown in the figure, this achieves uniform temperature distribution and efficient utilization of thermal energy.

[0047] In this embodiment, both the second ventilation hole 121 and the third ventilation hole 122 are oblong. In other embodiments, the shapes of the second ventilation hole 121 and the third ventilation hole 122 can be changed according to actual conditions. For example, the second ventilation hole 121 and the third ventilation hole 122 can both be square; or, the second ventilation hole 121 and the third ventilation hole 122 can both be round square; or, the second ventilation hole 121 and the third ventilation hole 122 can both be elliptical; or, the second ventilation hole 121 and the third ventilation hole 122 can both be triangular.

[0048] The cabinet 1 is also provided with a sixth ventilation hole 16 and a seventh ventilation hole 17, which are sequentially connected to the storage space 102. When hot air is continuously supplied from the first receiving cavity at the top of the cabinet 1 into the storage space 102, making the air pressure inside the storage space 102 greater than the outside air pressure, the hot air is sequentially discharged to the outside through the seventh ventilation hole 17 and the sixth ventilation hole 16 (the direction of hot air flow is as follows). Figure 2 (As shown).

[0049] In this embodiment, both the sixth ventilation hole 16 and the seventh ventilation hole 17 are oblong. In other embodiments, the shapes of the sixth ventilation hole 16 and the seventh ventilation hole 17 can be changed according to the actual situation. For example, the sixth ventilation hole 16 and the seventh ventilation hole 17 can both be square; or, the sixth ventilation hole 16 and the seventh ventilation hole 17 can both be round square; or, the sixth ventilation hole 16 and the seventh ventilation hole 17 can both be elliptical; or, the sixth ventilation hole 16 and the seventh ventilation hole 17 can both be triangular.

[0050] The cabinet door 4 is hinged to the cabinet body 1, and the cabinet door 4 can rotate around the cabinet body 1 to open or close the dryer.

[0051] This internal circulation dryer includes a cabinet 1, a hot air blower 2, and a circulating fan 3. The cabinet 1 has a cover plate 11 and a top plate 12, which are arranged from top to bottom on the top of the cabinet 1, forming a first receiving cavity and a second receiving cavity. The hot air blower 2 is located in the first receiving cavity, and the circulating fan 3 is located in the second receiving cavity. The cabinet 1 also has a partition 14, with an air duct 101 formed between the partition 14 and the right side wall of the cabinet 1, and a storage space 102 formed between the partition 14 and the left side wall of the cabinet 1. The bottom of the partition 14 has a first ventilation hole 141, and the first receiving cavity, air duct 101, ventilation hole, and storage space 102 are sequentially connected. The top plate 12 has a second ventilation hole 121 and a third ventilation hole 122, and the storage space 102, second ventilation hole 121, second receiving cavity, and third ventilation hole 122 are sequentially connected. When the external power is connected, the hot air blower 2 and the circulating fan 3 are started. The hot air blower 2, installed on the top of the cabinet 1, draws outside air into the first receiving cavity and heats it to obtain hot air. The hot air blower 2 delivers the obtained hot air to the air duct 101. After being transported through the air duct 101, the hot air is delivered from the first receiving cavity at the top of the cabinet 1 to the first ventilation hole 141 at the bottom of the partition 14 and enters the storage space 102. The circulating fan 3 drives the airflow through mechanical power to force the hot air in the storage space 102 to circulate, thereby achieving uniform temperature distribution and efficient heat energy utilization. In addition, the hot air blower 2 and the circulating fan 3 are located at the top of the cabinet 1, which can prevent water droplets or condensation on the clothes from dripping directly onto the hot air blower 2 and the circulating fan 3, eliminating safety hazards. This can solve the problems of low heat energy utilization, uneven drying, and safety hazards in existing dryers.
