detailed description

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model provides a pressure cooker capable of cooling the shell, including a shell assembly 1, an inner cover assembly 2 and a pot cover assembly 3. The inner cover component 2 is sleeved in the outer cover component 1 and keeps a cavity 4 between the inner cover component 2 and the outer cover component 1, and the gap can allow air to circulate between the outer cover component 1 and the inner cover component 2, and the pot The lid assembly 3 is hinged on the shell assembly 1, or the pot lid assembly 3 can also be set separately and can be disassembled from the pressure cooker. The pressure cooker also mainly plays the role of sealing the inner cover assembly 2 to ensure sufficient pressure in the inner cover assembly 2 during high-pressure cooking.

As shown in FIG. 2 , the shell assembly 1 includes a bottom cover 1 - 1 , a base 1 - 2 , a shell 1 - 3 and a middle ring 1 - 4 from bottom to top. Wherein each part can be integrally formed, in this embodiment it is set separately, facilitates processing, saves production cost, with regard to this embodiment, bottom cover 1-1 is installed in the middle part of base 1-2 close to the bottom position, and in The bottom cover 1-1 is also provided with some cooling holes 1-11. These cooling holes 1-11 are aimed at the heating parts of the inner cover assembly 2, and its effect is to prevent the internal components from being burned out due to the high temperature of the heating parts. The overflow heat is dissipated to the shell assembly 1 to ensure the safety of the pressure cooker. The shell 1-3 is installed on the base 1-2, the middle ring 1-4 is installed on the top of the shell 1-3, and the middle ring 1-4 is used to hinge the lid assembly 3. Meanwhile, the middle ring 1-4 also has the function of fixing the inner cover assembly 2.

As shown in Figure 2, the inner cover assembly 2 includes an inner cover 2-1, a heater 2-2 and an inner container 2-3, and the inner container 2-3 is arranged in the inner cover 2-1, while the inner container 2- There is also a certain gap between 3 and the inner cover 2-1. This setting is to prevent the external cold air from affecting the temperature of the inner tank 2-3, so that the heating effect is better, and the addition of the inner cover can also be better reinforced. The pressure resistance performance of the pressure cooker makes the pressure cooker have a higher pressure resistance capability, and the inner tank 2-3 and the inner cover 2-1 can also be regarded as a whole. The heater 2-2 is installed at the bottom of the inner cover 2-1 and is in contact with the inner container 2-3, and the heater 2-2 can also be installed at a position in contact with the side wall of the inner container 2-3. It is a common practice, and the heater 2-2 is installed at the bottom to align with the cooling holes 1-11 to facilitate the outward diffusion of the overflowing heat.

As shown in Figures 1 and 2 and Figure 3, an air blower 5 is provided on the shell assembly 1, and the air blower 5 is a fan, and its installation position is located on the side of the shell assembly 1 and is close to the middle ring position, so that the air blower is set 5 is to make the external colder air flow down from the top to achieve a better cooling effect, but it can always be placed in other parts, as long as the external colder air can be smoothly sent into the cavity, The bottom of the shell assembly 1 is provided with a convection port 6, the position of the convection port 6 is located on the same side as the air supply device 5, and it can also be located at other positions. It can be discharged around the entire cavity 4. In order to prevent the air flow from being discharged from the cooling holes and affecting the heating effect of the heater 2-2, a spoiler 7 is provided at the bottom of the shell assembly 1, and the spoiler 7 can guide the flow direction of the airflow. To prevent the airflow from flowing to the cooling holes 1-11 and guide the airflow to the convection opening 6, in this embodiment the spoiler 7 is arranged on the base 1-2.

The shell assembly 1 is also provided with a control device 8 and a power socket 9, and the power socket 9 is used to connect an external power source to provide electric energy for the control device 8, the heater 2-2 and the air supply device of the pressure cooker. The control device 8 is used to control the heater 2-2 and the blower 5.

According to the air supply device 5 described above, when the air supply can be controlled by the control device 8, a temperature control sensor can also be set in the pressure cooker, and the air supply device 5 can be opened automatically when the shell temperature reaches a certain temperature. It can be seen from the above description that the air supply device 5 transports the external air into the cavity, but in a specific implementation, the air in the cavity can also be drawn outward, so that the convection port 6 has played a role in this embodiment. The role of air supply device 5.

The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
