[0039] This embodiment discloses an elastic drive mechanism, a swing system including the elastic drive mechanism, and a cooking device including the swing system. Figures 1 to 3 As shown, the cooking device includes a box body 7 with a cooking cavity 71 formed therein, and a temperature measuring window 72 is provided on the wall of the box body 7. The swing system is arranged outside the box body 7 and can measure the temperature in the cooking cavity 71 through the temperature measuring window 72.

[0040] In order to prevent the steam and microwaves in the cooking cavity 71 from leaking out, in the present embodiment, an interlayer (not shown) is sealed and covered on the temperature measuring window 72. The interlayer is made of a material with strong infrared penetration. The temperature measuring window 72 is sealed without affecting the normal temperature measurement. In addition to preventing the steam and microwaves from leaking out, it can also reduce the amount of high temperature radiation in the cooking cavity 71 to the outside to a certain extent, so that the swing system can work in a suitable temperature environment.

[0041] like Figure 4 and Figure 5 As shown, the swing system includes an elastic drive mechanism 1, a temperature measuring device 2, a support frame 3, a mounting box 4 and a wind drive assembly. The temperature measuring device 2 is located at the temperature measuring window 72 (such as Figure 2 In addition, the temperature of the cooking cavity 71 (as shown) can be measured through the temperature measuring window 72. Figure 3 The specific structure of the temperature measuring device 2 is not limited, as long as it can realize remote temperature measurement. In this embodiment, the temperature measuring device 2 is an infrared temperature measuring instrument, which can accurately measure the temperature of the food in the cooking cavity 71, automatically adjust the cooking power and cooking time according to the food temperature, and achieve a good cooking effect, which can prevent the food from being undercooked or overcooked, and the cooked food tastes better.

[0042] The temperature measuring device 2 is detachably connected to the support frame 3, and the integral structure formed by the temperature measuring device 2 and the support frame 3 is hinged in the installation box 4. Specifically, a hinge shaft 31 is provided on the support frame 3, and a hinge hole 43 is provided on the side of the installation box 4, and the hinge shaft 31 is passed through the hinge hole 43. The support frame 3 can rotate around the hinge shaft 31, and the temperature measuring device 2 can rotate synchronously with the support frame 3.

[0043] like Figure 3 As shown, area A is the temperature measuring range when the temperature measuring device 2 is in the initial position. When the temperature measuring device 2 rotates with the support frame 3, the temperature measuring range can swing from area B to area C to achieve temperature detection over the entire area. Even if the food to be cooked is placed in a relatively biased position, the temperature measuring device 2 can still measure the temperature of the food to be cooked by swinging. The adjustment of cooking power and cooking time is more targeted, and the cooking effect is better.

[0044] like Figure 5 As shown, the elastic drive mechanism 1 includes a piston rod, an elastic member 12 and a driving wheel 14. Specifically, the first end of the piston rod has a pressure-bearing portion arranged facing the wind, and the piston rod is arranged to be able to move toward the second end along its own extension direction under pressure. The elastic member 12 acts on the piston rod so that the piston rod always has a tendency to return to the first end along its own length direction. The driving wheel 14 is arranged to be able to rotate around its own axis A, and the piston rod can drive the driving wheel 14 to rotate when in contact with the driving wheel 14. Figure 4 As shown, the driving wheel 14 is connected to the support frame 3, the piston rod is partially located in the mounting box 4, the elastic driving mechanism 1 can drive the support frame 3 to swing around the hinge axis 31, and the wind drive assembly is used to apply pressure to the compressed part of the piston rod.

[0045] When the wind force is greater than the set value, the piston rod can move along the axial direction under the push of the wind force; when the wind force is less than the set value, the elastic member 12 can drive the piston rod to reset; when the wind force is equal to the set value, the elastic drive mechanism 1 maintains the current state unchanged. In this embodiment, the elastic member 12 is a spring, and the piston rod is inserted into the spring. The specific structure of the piston rod is not limited, as long as it can drive the driving wheel 14 to rotate. In this embodiment, the piston rod has a first rod body 11 and a second rod body 13 arranged in sequence along its own moving direction, wherein the pressure-bearing portion is arranged at the end of the first end of the first rod body 11, and the elastic member 12 is a spring sleeved outside the first rod body 11. The second rod body 13 is located in the installation box 4 (such as Figure 4As shown in FIG. 1 , the driving wheel 14 cooperates with the second rod 13, and the driving wheel 14 is connected to the support frame 3. When the first rod 11 moves along the axial direction under the impetus of wind, the second rod 13 can move synchronously with the first rod 11. The linear movement of the second rod 13 can drive the driving wheel 14 to rotate around its axis A, and the driving wheel 14 drives the support frame 3 to swing around the hinge shaft 31, so that the temperature measuring device 2 can rotate synchronously with the support frame 3, and scan the food temperature in the cooking cavity 71 over a large range, so as to realize the cooking cavity 71 (as shown in FIG. 1 ). Figure 3 Vertical three-dimensional temperature measurement inside.

[0046] The specific manner in which the driving wheel 14 cooperates with the second rod 13 is not limited. In this embodiment, the second rod 13 is a rack having a first tooth portion, and the driving wheel 14 is a gear having a second tooth portion on the outer periphery. The first tooth portion of the second rod 13 meshes with the second tooth portion of the driving wheel 14. Both the rack and the gear are technically mature structures, with a wide range of varieties and specifications, and low product cost. When the rack and the gear are meshed, the transmission effect is good, the linear movement of the rack can be smoothly converted into the rotation of the gear, the action response is fast, and the energy consumption during the transmission process is low.

[0047] On the basis of the above structure, the elastic drive mechanism 1 further includes an end cap 15 as a pressure-bearing part, the diameter of the end cap 15 is larger than the diameter of the first rod 11, and the end cap 15 is connected to the end of the first rod 11 away from the second rod 13. Figure 4 As shown, a hollow mounting tube 41 is provided on the mounting box 4, and the end cap 15 and the first rod body 11 are both provided in the mounting tube 41. The diameter of the end cap 15 is the same as the inner diameter of the mounting tube 41, ensuring that the wind force can fully act on the end cap 15, and no airflow will enter the mounting tube 41 from the gap between the end cap 15 and the mounting tube 41; the diameter of the first rod body 11 is smaller than the inner diameter of the mounting tube 41, reducing the contact area between the elastic drive mechanism 1 and the mounting tube 41, reducing the energy consumption caused by friction, and being able to push the elastic drive mechanism 1 with more effort.

[0048] The specific connection structure between the end cap 15 and the first rod body 11 is not limited. In this embodiment, the second side of the end cap 15 has a limiting protrusion 17, and the first end of the first rod body 11 has a limiting groove matching the limiting protrusion 17. Specifically, the end of the first rod body 11 is provided with a blind hole (not shown) as a limiting groove, and the limiting protrusion 17 is penetrated in the blind hole. The matching structure of the limiting protrusion 17 and the blind hole prevents the end cap 15 from moving relative to the first rod body 11 in the radial direction, ensuring that the first rod body 11 with a smaller diameter will not shake in the radial direction in the mounting tube 41.

[0049] On the basis of the above structure, a connector 16 is connected between the first rod body 11 and the second rod body 13, and the extension direction of the connector 16 intersects with the extension direction of the first rod body 11. The extension direction (axis) of the first rod body 11 is parallel to the extension direction (axis) of the second rod body 13, the second rod body 13 deviates from the piston rod 11 along the radial direction of the first rod body 11, and the driving wheel 14 is located on the moving path of the second rod body 13. That is, the second rod body 13 is not located on the extension line of the first rod body 11, but the second rod body 13 and the first rod body 11 are parallel to each other at a distance. The specific shape and size of the connector 16 are not limited, and can be determined according to the position of the driving wheel 14, fully adapting to the internal space of the swing system, ensuring that there is no interference with the components in the swing system, and having a wide range of applications.

[0050] like Figure 4 , Figures 6 to 8 As shown, the swing system further includes an air duct 5 and a fan (not shown), and the air duct 5 is connected to the mounting box 4. The fan can pump low-temperature air in the surrounding environment into the air duct 5 to form a heat dissipation airflow in the air duct 5. The heat dissipation airflow can reduce the temperature of the temperature measuring device 2 and its surrounding environment, improve the measurement accuracy of the temperature measuring device 2, and extend the service life of the temperature measuring device 2; the heat dissipation airflow can also apply wind force to the first rod body 11 to push the first rod body 11 to move along its axial direction.

[0051] In this structure, there is no need to set a dedicated motor to drive the temperature measuring device 2 and the support frame 3 to swing. The heat dissipation airflow is used to replace the dedicated motor, which reduces the cost, reduces the size of the cooking device, saves energy and reduces noise. The heat dissipation airflow can drive the temperature measuring device 2 and the support frame 3 to swing to a set angle, so that the cooking cavity 71 (such as Figure 3 The vertical three-dimensional scanning temperature measurement has a wider temperature measurement range.

[0052] On the basis of the above structure, the mounting tube 41 is connected to the air duct 5, the end cover 15 and the elastic member 12 are located in the mounting tube 41, and a part of the first rod body 11 is located in the mounting tube 41. One end of the elastic member 12 abuts against the connection between the mounting tube 41 and the mounting box 4, and the other end of the elastic member 12 abuts against the surface of the leeward side of the end cover 15. After the heat dissipation airflow enters the mounting tube 41, wind pressure is formed. When the thrust of the heat dissipation airflow is greater than the set value, the heat dissipation airflow can push the end cover 15 and the first rod body 11 to move toward the inner cavity of the mounting box 4, and the elastic member 12 is compressed; when the thrust of the heat dissipation airflow is less than the set value, the elastic member 12 releases the elastic force, pushing the end cover 15 and the first rod body 11 to move away from the inner cavity of the mounting box 4 until the end cover 15 and the first rod body 11 are reset.

[0053] In order not to affect the heat exchange between the heat dissipation airflow and the temperature measuring device 2 in the installation box 4, a plurality of air inlet holes 42 are provided on the tube wall of the installation tube 41, and the extension direction of the air inlet holes 42 is parallel to the axis of the installation tube 41. The air inlet holes 42 penetrate the tube wall of the installation tube 41, that is, one end of the air inlet holes 42 is connected to the air duct 5, and the other end of the air inlet holes 42 is connected to the inside of the installation box 4. Regardless of whether the first rod body 11 moves or not, the heat dissipation airflow can enter the installation box 4 through the air inlet holes 42, and can continuously exchange heat with the temperature measuring device 2, with a good heat dissipation effect.

[0054] The specific structure of the wind-driven assembly is not limited, as long as it can apply wind pressure to the pressure-bearing part of the piston rod, and may include but is not limited to a fan (not shown) and an air duct 5, wherein the fan can deliver heat dissipation airflow to the air duct 5. On the basis of the above structure, one end of the air duct 5 connected to the mounting box 4 forms a connecting terminal 51, and the cross-sectional area of ​​the connecting terminal 51 gradually decreases along the airflow direction. When the total air volume remains unchanged, the reduction of the channel area will increase the airflow speed; the faster the airflow speed, the stronger the impact, and the greater the wind pressure acting on the end cover 15, making it easier to push the end cover 15 and the piston rod.

[0055] like Figure 4 , Figure 6 and Figure 8 As shown, the swing system further includes a damper 6. The damper 6 is connected between the support frame 3 and the mounting box 4. Specifically, one end of the damper 6 is hinged on the support frame 3, and the other end of the damper 6 is hinged on the mounting box 4. When the support frame 3 swings around the hinge shaft 31, the length and spatial posture of the damper 6 are adjusted accordingly, providing a supporting force for the support frame 3 without hindering the swing of the support frame 3, thereby preventing the support frame 3 from shaking during the blowing of the heat dissipation airflow, and making the temperature measurement more accurate; and after the thrust of the heat dissipation airflow decreases, the damper 6 can reset the end cover 15 and the piston rod together with the elastic member 12.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, but may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
