[0022] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0023] The utility model discloses a drying air inlet device for a dishwasher, Figures 1 to 5 As shown, it includes a bottom frame 1, on which a circulation condensation mechanism 2 and a hot and cold air inlet mechanism 3 are provided. The inlet end of the circulation condensation mechanism 2 is used to inhale water vapor in the inner tank of the dishwasher, and the outlet end of the hot and cold air inlet mechanism 3 is connected to the inner tank of the dishwasher. An air intake fan 4 is provided on the side of the air intake end of the hot and cold air inlet mechanism 3. The distal end port of the circulation condensation mechanism 2 is connected to the first air intake end of the air intake fan 4, and the second air intake end of the air intake fan 4 is used to inject air into the hot and cold air inlet mechanism 3.

[0024] In the above structure, the circulation condensing mechanism 2 and the hot and cold air inlet mechanism 3 are both fixedly mounted on the bottom frame 1, and the circulation condensing mechanism 2 has an internal circulation function and an external circulation function. In the external circulation mode, the proximal port of the circulation condensing mechanism 2 is opened to directly discharge the airflow drawn from the inner tank. In the internal circulation mode, the proximal port of the circulation condensing mechanism 2 is closed, and the circulation condensing mechanism 2 draws water vapor from the inner tank of the dishwasher. After condensation by the circulation condensing mechanism 2, the airflow is discharged to the first air inlet end of the air intake fan 4. When the air intake fan 4 is in operation, air is simultaneously inhaled through the first air inlet end and the second air inlet end, thereby using a single fan to draw air from the circulation condensing mechanism and the outside to the hot and cold air inlet mechanism at the same time, which not only simplifies the air path, but also makes reasonable use of the internal space of the dishwasher.

[0025] In this embodiment, the air intake fan 4 is a centrifugal fan having two air intake ends and one air outlet end. For the working principle of the circulation condensation mechanism 2, please refer to the content in the patent document with publication number CN220385006U.

[0026] In the present embodiment, the distal end of the circulating condensing mechanism 2 and the lower end of the cold and hot air inlet mechanism 3 are both fixedly connected to the base frame 1. In order to achieve airflow conduction on the basis of fixed connection, in the present embodiment, a conducting cavity 10 is formed on the base frame 1, and the distal end port of the circulating condensing mechanism 2 and the first air inlet end of the air inlet fan 4 are both connected to the conducting cavity 10.

[0027] In practical applications, the conductive cavity 10 is a cavity structure integrally formed with the bottom frame 1 .

[0028] In order to better cooperate with the circulating condensation mechanism 2, in this embodiment, Figure 2 and Figure 3 As shown, a receiving port 11 is formed between the conduction cavity 10 and the bottom frame 1, and a downwardly extending sinking port 20 is formed at the distal end port of the circulation condensation mechanism 2, and the sinking port 20 is arranged in the receiving port 11. A conduction port 12 is opened at the side of the conduction cavity 10, and the conduction port 12 and the sinking port 20 are connected to each other and the connection between the two is sealed. Among them, the distal end of the circulation condensation mechanism 2 can be extended to between the conduction cavity 10 and the bottom frame 1 by setting the sinking port 20, so as to better communicate with the conduction port 12 opened at the side of the conduction cavity 10.

[0029] As a preferred embodiment, an air inlet cover 30 is provided on the side of the cold and hot air inlet mechanism 3, and the air inlet cover 30 is provided on the top of the conduction cavity 10 and the connection between the two is sealed. Figure 4 The air intake hood 30 includes an arc-shaped hood top 31 , and the first air intake end of the air intake fan 4 is aligned with the arc-shaped hood top 31 .

[0030] In the above structure, the air intake cover 30 can not only cover the conduction cavity 10, but also provide a suction space for the air intake fan 4 by setting the arc-shaped cover top 31, so as to make the air path structure more reasonable.

[0031] For the specific structural layout of the bottom frame 1 circulation condensation mechanism 2 and the cold and hot air inlet mechanism 3, please refer to Figure 1 and Figure 5 The circulation condensation mechanism 2 is fixed to the front end of the bottom frame 1 , and the conduction cavity 10 is close to the corner of the bottom frame 1 .

[0032] For the internal structure of the cold and hot air inlet mechanism 3, see Figure 6 and Figure 7 An electric heating device 32 is provided in the cold and hot air inlet mechanism 3, and the air outlet end of the electric heating device 32 is covered with a switch baffle 33, and the upper end of the switch baffle 33 is hingedly connected to the cold and hot air inlet mechanism 3.

[0033] Furthermore, a sterilization and antibacterial device is provided near the outlet of the hot and cold air inlet mechanism 3. The sterilization and antibacterial device includes an ion generator 34, and a driver 35 is provided at the upper end of the hot and cold air inlet mechanism 3. The ion generator 34 and the driver 35 are connected by a wire.

[0034] The electric heating device 32 is used to heat the airflow passing through the hot and cold air inlet mechanism 3, so as to send hot air into the inner pot. When the dishes are washed, the driver 35 can also be used to control the ion generator 34 to generate ions, so that the ions enter the inner pot of the dishwasher along with the airflow. On this basis, the utility model can automatically cover and close the air outlet end of the electric heating device 32 when there is no wind in the hot and cold air inlet mechanism 3 by setting the switch baffle 33, so as to play a role in moisture-proof and insect-proof.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
