Description

Technical Field

[0002] Cooking equipment such as microwave ovens and steam ovens with microwave functions include a furnace body and a door body. The furnace body defines a cooking cavity for heating food. The door body can be installed at the cavity opening of the cooking cavity in an openable and closable manner, and the user takes in and puts food through the cavity opening of the cooking cavity. Cooking equipment with microwave functions usually has a metal mesh plate in the door body to shield microwaves. When the user uses the cooking equipment to cook ingredients, if the user observes the ingredients in the cooking cavity through the mesh of the metal mesh plate, due to the small size of the mesh, it is difficult for the user to clearly view the current state of the food, and the cooking time cannot be controlled, resulting in a poor user experience. Moreover, when checking the state of food through the metal mesh plate, the user's eyes need to be close to the door body. Frequent observation of food through the metal mesh plate may cause the eyes to be irradiated by microwaves and cause damage.

[0003] Currently, there are cooking devices on the market that use cameras to observe the status of food in the cooking cavity, but the microwaves in the cooking cavity will interfere with the camera's shooting, causing the camera to capture the picture with undesirable phenomena such as moiré, snowflakes, and horizontal bands, affecting the user's observation of the cooking status of food and providing a poor user experience.

[0042] Embodiment 1

[0043] like Figure 1 As shown, this embodiment provides a cooking device (such as a microwave oven, a microwave oven, etc.), including a body 1 and a camera assembly 2 arranged on the body. The body 1 encloses a cavity for cooking food. Specifically, in combination with Figure 2 The machine body 1 includes an inner pot 11 and a door assembly 12. The inner wall of the inner pot 11 can reflect microwaves so that the microwaves are radiated to the food to cook the food. The interior of the inner pot 11 is a cooking cavity. The door assembly 12 can be opened and closed at the cavity opening of the cooking cavity so that the user can take in and put in the food. After the door assembly 12 is buckled into the cavity opening of the cooking cavity, the above-mentioned cavity is formed, and the food is heated in the cavity environment. That is, the inner pot 11 and the door assembly 12 of the machine body 1 are jointly arranged to form the above-mentioned cavity.

[0044] See also Figure 3 The camera assembly 2 includes a camera 21, which is used to capture images of food in the cavity. A microwave shielding structure is provided between the camera 21 and the cavity. In the cooking device, since the camera assembly 2 is provided in the body 1, the current state of the food in the cavity can be clearly viewed through the camera 21 of the camera assembly 2, without the need to frequently observe the cavity with the naked eye, thereby improving safety and user experience. Moreover, the microwave shielding structure provided between the camera 21 and the cavity can effectively shield the interference of microwaves emitted by the cooking device on the camera 21, and prevent the camera 21 from being affected by microwaves, resulting in the occurrence of undesirable phenomena such as reticulation, snowflakes, and horizontal bands in the captured images, thereby ensuring that the food images observed by the user are clear and stable, thereby improving the user experience.

[0045] In this embodiment, the camera assembly 2 is installed on the door assembly 12 used to block or open the cooking cavity. Figure 2As shown, it is a schematic diagram of the door assembly 12 provided in this embodiment. A cavity 120 is provided in the door assembly 12. The microwave shielding structure includes a mesh plate 121 for shielding microwaves arranged in the cavity 120. The mesh plate 121 is outside the cavity. The mesh size of the mesh plate 121 is precisely calculated to block the penetration of microwaves, play a role in shielding microwaves, and improve the safety of use. The camera assembly 2 is arranged in the cavity 120 and installed on the side of the mesh plate 121 away from the cooking cavity. The size of the camera 21 is not larger than the mesh size of the mesh plate 121. At this time, the camera 21 can shoot the picture in the cooking cavity through the mesh on the mesh plate 121, so that the user can clearly view the current state of the food in the cooking cavity through the camera 21, without frequently using the naked eye to observe the cooking cavity through the mesh plate 121, thereby improving safety and user experience. Since the camera assembly 2 is located on the side of the mesh plate 121 facing away from the cooking cavity, the influence of microwaves on the camera assembly 2 can be shielded as much as possible, and the camera assembly 2 can be prevented from being interfered by microwaves and unable to shoot smoothly.

[0046] Furthermore, the camera assembly 2 is connected to the terminal device for viewing the captured images through the terminal device. For example, the terminal device can be a display screen installed outside the door assembly 12 for easy viewing by the user. Of course, the display screen can also be detachably installed on the cooking device and wirelessly connected to the camera assembly 2. The cooking cavity image can be viewed within a certain area away from the cooking device, and the user does not need to go to the kitchen to view it, which is more practical. Furthermore, the terminal device can also be a mobile phone, tablet computer, etc., and the cooking cavity image can be viewed through an APP matched with the camera assembly 2.

[0047] See also Figure 2 The door assembly 12 includes an inner glass 123, a middle glass 124 and an outer glass 125 which are arranged in sequence from the inside to the outside, the inner glass 123 faces the cooking cavity, the cavity 120 is between the inner glass 123 and the outer glass 125, and the mesh plate 121 is located between the middle glass 124 and the outer glass 125. The arrangement of the inner glass 123 and the outer glass 125 can protect the camera assembly 2 from corrosion and pollution in the cavity 120, ensure good shooting images, and extend the service life of the camera assembly 2.

[0048] The inner glass 123 and the middle glass 124 can effectively block the heat radiation from the cooking cavity. On the one hand, it can prevent the door assembly 12 from being overheated and causing burns to the user when opening the door assembly 12. On the other hand, it can effectively reduce the heat loss inside the cooking cavity, ensure the cooking temperature, and speed up the cooking speed. Further, the inner glass 123 and the outer glass 125 are set to be transparent at least in the position facing the camera assembly 2 to avoid blocking the camera assembly 2. It can be understood that the inner glass 123 and the outer glass 125 can be transparent as a whole, or contain a certain area of ​​transparent area, and the camera assembly 2 can capture the food image inside the cooking cavity through the transparent area. In addition, since the mesh plate 121 is usually made of metal, it is set behind the inner glass 123 and the middle glass 124, which can prevent the deformation of the metal mesh plate 121 caused by the heat radiation from the cooking cavity, and prevent the microwave shielding function of the mesh plate 121 from decreasing.

[0049] The outer glass 125 is usually made of a transparent material, and the image inside the cooking cavity can be observed through the outer glass 125 and the mesh of the mesh plate 121. When the camera assembly 2 is accidentally damaged or fails, it can be temporarily observed through the mesh plate 121. That is, the existence of the mesh plate 121 not only plays a role in shielding microwaves, but also serves as a backup observation path when the camera assembly 2 is damaged. The door assembly 12 provides two observation methods to avoid being unable to observe the cooking state when the camera assembly 2 fails, and the reliability is higher.

[0050] If the size of the camera 21 is larger than the size of the mesh opening on the mesh plate 121, a first observation hole is required to be opened on the mesh plate 121 to avoid blocking the camera 21. The aperture of the first observation hole is larger than the aperture of the mesh opening on the mesh plate 121. This will result in the first observation hole not being able to play the role of microwave shielding like the mesh opening, and microwaves will leak at the first observation hole. To solve this problem, see Figure 3 On the basis of the mesh plate 121, the microwave shielding structure further includes a metal shielding tube 22 that can shield microwaves. The metal shielding tube 22 contacts the side of the mesh plate 121 away from the cavity and is covered outside the first observation hole to prevent microwaves from leaking in the gap due to the gap between the metal shielding tube 22 and the mesh plate 121. The axial length of the metal shielding tube 22 is greater than the axial length of the mesh. The camera 21 captures the image in the cavity through the inner cavity of the metal shielding tube 22 and the first observation hole, further shielding the interference of microwaves on the camera 21, and ensuring the image shooting quality of the camera 21. In this embodiment, the metal shielding tube 22 is a component installed in the camera assembly 2.

[0051] Specifically, the cutoff frequency of the metal shielding tube 22 (the frequency below which waves cannot propagate inside it) is greater than the microwave frequency of the cooking equipment, so as to prevent microwaves from being transmitted through the metal shielding tube 22 to the position of the camera 21, thereby effectively blocking the microwaves and protecting the camera 21.

[0052] Specifically, the circular pipe of the metal shielding tube 22 forms a circular waveguide, and the circular waveguide has a cutoff frequency. The cutoff frequency can be approximately calculated by the following formula: fc = 1.841×(c / (2×π×d). Wherein fc is the cutoff frequency, c is the speed of light (about 3×10 8 m / s), d is the radius of the circular waveguide. For example, the radius of the circular metal shielding tube 22 is 8 mm, and the cutoff frequency fc=10.98 GHz can be obtained by substituting it into the formula. The frequency used by the cooking device is 2.45 GHz, so the cutoff frequency fc=10.98 GHz is greater than the frequency 2.45 GHz used by the cooking device, so microwaves cannot propagate outward through the circular metal shielding tube 22.

[0053] See also Figure 3 The axes of the camera 21, the metal shielding tube 22 and the first observation hole are consistent, ensuring that the camera 21 has a good field of view.

[0054] Reference Figure 3 and Figure 4 The inner hole of the metal shielding tube 22 includes a straight hole 221 and a horn hole 222 that are connected. The straight hole 221 is located between the camera 21 and the horn hole 222, and the straight hole 221 is connected to the small diameter end of the horn hole 222. The large diameter end of the horn hole 222 is close to the first observation hole on the mesh plate 121. The small diameter ends of the straight hole 221 and the horn hole 222 have a diameter a, and the large diameter end of the horn hole 222 has a diameter b, and b>a.

[0055] The straight hole 221 can form a circular waveguide to ensure effective shielding of microwaves. The speaker hole 222 is provided at one end close to the first observation hole to expand the field of view of the camera 21, minimize the obstruction of the front side of the camera 21, and facilitate the shooting of the entire cooking cavity area. Furthermore, the diameter of the first observation hole is not larger than the diameter b of the large diameter end of the speaker hole 222, so that all microwaves transmitted through the first observation hole can enter the metal shielding tube 22 and be blocked, preventing the first observation hole from being set too large and causing microwave leakage. In this embodiment, the diameter of the first observation hole is b, which is consistent with the diameter of the large diameter end of the speaker hole 222.

[0056] Optionally, the distance between the camera 21 and the mesh plate 121 is adjustable. That is, the camera 21 can be relatively close to or away from the mesh plate 121 to increase or decrease the range of the camera 21 to capture images.

[0057] Specifically in this embodiment, see Figure 3 , Figure 5 as well as Figure 6The camera assembly 2 also includes a mounting seat 23, which is connected to the mesh plate 121. The mounting seat 23 is provided with a mounting cavity 231, the cavity opening of the mounting cavity 231 faces the cooking cavity, and the camera 21 is provided on the inner bottom wall of the mounting cavity 231. The cross section of the mounting cavity 231 is circular, and its inner peripheral wall is provided with an internal thread structure. One end of the metal shielding tube 22 is rotatably connected to the mesh plate 121, and the outer wall of the other end of the metal shielding tube 22 is provided with an external thread structure. The metal shielding tube 22 is threadedly connected with the internal thread structure of the mounting cavity 231 through the external thread structure, on the one hand, the metal shielding tube 22 and the mounting seat 23 are fixedly connected, and on the other hand, by screwing the metal shielding tube 22, the mounting seat 23 can be moved along the axial direction of the metal shielding tube 22 under the action of the thread rotation, so as to drive the camera to approach or move away from the mesh plate 121, thereby adjusting the camera range. The threaded connection does not need to destroy the inner wall structure of the metal shielding tube 22, ensuring its microwave shielding function.

[0058] See also Figure 5 and Figure 6 The camera assembly 2 further includes a mounting plate 24 and a guide column 25. The mounting plate 24 is attached to and connected to the mesh plate 121. The metal shielding tube 22 is rotatably connected to the mounting plate 24. The mounting seat 23 is spaced apart from the mounting plate 24. The space between the mounting seat 23 and the mounting plate 24 reserves space for the operation of screwing the metal shielding tube 22. Figure 3 A window 241 is provided on the mounting plate 24 , and the first observation hole is exposed through the window 241 to prevent the mounting plate 24 from blocking the field of view of the camera 21 .

[0059] See also Figure 5 and Figure 6 The guide column 25 is connected to the mounting plate 24, and an ear plate 232 is protruding from the mounting seat 23. The ear plate 232 is provided with a sliding hole, and the ear plate 232 can be slidably mounted on the guide column 25 through the sliding hole. In the process of screwing the metal shielding tube 22, the mounting seat 23 moves along the axial direction of the metal shielding tube 22, and at the same time, the ear plate 232 slides along the guide column 25. The setting of the guide column 25, on the one hand, limits the rotation of the mounting seat 23 around the axis, prevents the mounting seat 23 from rotating when the metal shielding tube 22 is screwed, and ensures that the mounting seat 23 can only drive the camera 21 to move linearly in the direction of approaching or moving away from the mesh plate 121; on the other hand, the setting of the guide column 25 plays a good guiding role in the movement of the mounting seat 23, making the movement of the mounting seat 23 more accurate and stable, and avoiding deviation.

[0060] Furthermore, an ear plate 232 is provided on each of the opposite sides of the mounting seat 23, and correspondingly, two guide columns 25 are provided on the mounting plate 24. The two ear plates 232 can be slidably mounted on the two guide columns 25 one by one, thereby improving the movement stability of the mounting seat 23 and further improving the movement accuracy of the mounting seat 23, and making the mounting seat 23 evenly stressed during the process of screwing the metal shielding tube 22.

[0061] More specifically, see Figure 5 and Figure 6 A connecting tube 243 is provided on the mounting plate 24, and one end of the guide column 25 is installed in the connecting tube 243. For example, one end of the guide column 25 for connecting with the connecting tube 243 is provided with an external thread, and the connecting tube 243 is provided with an internal thread, and the external thread is screwed with the internal thread, and the guide column 25 can be connected to the mounting plate 24 by screwing the guide column 25 into the connecting tube 243.

[0062] In other embodiments, the metal shielding tube 22 can also be fixedly connected to the mesh plate 121, and the mounting seat 23 can be threadedly connected to the metal shielding tube 22. By screwing the mounting seat 23, the front and rear positions of the camera 21 can be adjusted, thereby adjusting the distance between the camera 21 and the mesh plate 121.

[0063] In this embodiment, see Figure 4 The diameter of the first observation hole is b, and the diameter of the window 241 opened on the mounting plate 24 is e, e>b, ensuring that the camera 21 will not be blocked.

[0064] Further, see Figure 3 and Figure 6 In order to realize the rotation connection of the metal shielding tube 22 on the mounting plate 24, in this embodiment, a limiting sleeve 26 is provided on the mounting plate 24. The limiting sleeve 26 includes a sleeve 261, one end of which is fixedly connected to the mounting plate 24, and the other end is connected to an axial retaining ring 262. A stop shoulder 223 is convexly provided on the outer wall of the metal shielding tube 22, and the stop shoulder 223 is rotatably arranged in the sleeve 261. The axial retaining ring 262 limits the stop shoulder 223 along the axial direction of the metal shielding tube 22. In this way, the metal shielding tube 22 can only rotate relative to the mounting plate 24 around the axial direction, and due to the limiting effect of the axial retaining ring 262 on the stop shoulder 223, the metal shielding tube 22 cannot move along its axial direction, so that when the metal shielding tube 22 is rotated, the mounting seat 23 drives the camera 21 to approach or move away from the mesh plate 121.

[0065] Further, see Figure 3 The end of the sleeve 261 away from the axial retaining ring 262 is provided with a mounting ring 263, which is protruding from the outer wall of the sleeve 261 and is fixed to the mounting plate 24 by means of silicone adhesive. Figure 3 and Figure 7 The mounting plate 24 is provided with an annular adhesive groove 242, which is used to fill the adhesive groove 242 to achieve the bonding of the mounting plate 24 and the mesh plate 121. The adhesive groove 242 can be filled with a sufficient amount of adhesive, and the bonding area between the mounting plate 24 and the mesh plate 121 can be increased to ensure a stable connection without falling off. The adhesive can be silicone, which is firmly bonded.

[0066] See also Figure 3 and Figure 5 The mounting base 23 is provided with a plug-in port 233 for realizing the communication connection between the electronic device and the camera 21. For example, the wiring of the display screen installed on the front side of the door body assembly 12 is plugged into the plug-in port 233 to realize image transmission.

[0067] In some embodiments, the microwave shielding structure may not use the metal shielding tube 22 , for example, a transparent electromagnetic shielding film may be selected to shield microwaves without blocking the camera 21 .

[0068] like Figure 1 and Figure 2 As shown, the door assembly 12 is provided with a heat dissipation port 122 connected to the cavity 120, and the heat dissipation port 122 is configured to allow airflow to pass through, and the airflow takes away the heat emitted by the camera assembly 2 to prevent overheating and damage to the camera 21. Moreover, the airflow passed into the cavity 120 can dissipate heat for the door assembly 12 to prevent overheating of the door assembly 12 and cause burns.

[0069] In the cooking device provided in this embodiment, see Figure 1 A cooling fan 3 and an air duct cover 4 are also provided on the body 1 above the inner tank 11. A cooling air duct 5 is provided between the air duct cover 4 and the top wall of the body 1. The air inlet of the cooling air duct 5 is connected to the air outlet of the cooling fan 3. Figure 8 The air outlet of the heat dissipation duct 5 is directly opposite to and connected to the heat dissipation port 122 on the door assembly 12. After the heat dissipation fan 3 is started, airflow can be generated in the heat dissipation duct 5, and the airflow then enters the cavity 120 of the door assembly 12 through the heat dissipation port 122 to achieve heat dissipation of the door assembly 12 and the camera assembly 2. Figure 2 and Figure 8 As shown by the straight arrow in the middle, it indicates the flow direction of the airflow in the heat dissipation duct 5 and the door body assembly 12.

[0070] In other embodiments, a fan for introducing airflow may be directly disposed at the location of the heat dissipation port 122 , so as to achieve heat dissipation for the door assembly 12 and the camera assembly 2 .

[0071] See also Figure 2The door assembly 12 is also connected with a hinge assembly 126, a door handle 127 and a lock hook 128. The hinge assembly 126 is located at the lower side of the door assembly 12, and is used to realize the rotation connection between the door assembly 12 and the machine body 1. The door handle 127 and the lock hook 128 are arranged on the upper side of the door assembly 12, and the door handle 127 is located on the outer side of the door assembly 12 for the user to pull. The lock hook 128 is arranged on the inner side of the door assembly 12, and is used to be detachably locked with the lock hook 128 arranged on the machine body 1, so that the door assembly 12 remains closed during the cooking process.

[0072] In summary, in this embodiment, the microwave shielding structure can be provided to shield the interference of microwaves to the camera 21. It should be emphasized that the microwave shielding structure may only include the mesh plate 121, and the camera 21 is located on the side of the mesh plate 121 facing away from the cavity. At this time, the size of the camera 21 should not be larger than the hole size of the mesh plate 121 to prevent the mesh plate 121 from blocking the camera 21. At this time, the camera 21 shoots the image inside the cavity through the mesh holes of the mesh plate 121; the microwave shielding structure can also be a combination of the mesh plate 121 and the metal shielding tube 22. At this time, the size of the camera 21 is larger than the mesh size, and a first observation hole needs to be opened on the mesh plate 121. The camera 21 shoots the image inside the cavity through the inner cavity of the metal shielding tube 22 and the first observation hole. The metal shielding tube 22 is used to shield the microwaves leaking from the first observation hole. For details of the specific structure, please refer to the above content.

[0073] Embodiment 2

[0074] Based on the same inventive concept as that of the first embodiment, this embodiment provides a cooking device, which differs from the first embodiment in that:

[0075] In this embodiment, the camera assembly 2 is arranged on the inner tank 11 of the body 1 rather than the door assembly 12, and the camera 21 is located outside the inner tank, for example, installed on the top or one side of the inner tank 11, and can also capture the scene inside the cavity.

[0076] Taking the example of the camera assembly 2 being installed on the top of the inner pot 11, the microwave shielding structure may only include the mesh plate 121. The mesh plate 121 is outside the cavity and above the inner pot 11. The mesh size of the mesh plate 121 is precisely calculated to block the penetration of microwaves and play a role in shielding microwaves. At this time, the size of the camera 21 is not larger than the mesh size of the mesh plate 121. The camera 21 can shoot the picture in the cooking cavity from the top perspective through the mesh on the mesh plate 121, so that the user can clearly view the current state of the food in the cooking cavity through the camera 21. In this solution, the mesh plate 121 prevents the camera from being interfered with by shielding microwaves.

[0077] In this embodiment, for the scene where the camera assembly 2 is arranged on the inner tank 11, if the size of the camera 21 is larger than the size of the mesh opening on the mesh plate 121, the microwave shielding structure can be a combination of the mesh plate 121 and the metal shielding tube 22. The camera assembly 2 adopts the same structure as the camera assembly 2 in the first embodiment, such as Figure 3 , Figure 5 as well as Figure 6 As shown. Specifically, a second observation hole is provided on the mesh plate 121 at the top of the inner pot 11 to avoid blocking the camera 21 from shooting. The aperture of the second observation hole is larger than the aperture of the mesh hole on the mesh plate 121. To prevent microwave leakage at the second observation hole, the metal shielding tube 22 is in contact with the side of the mesh plate 121 away from the cavity and is covered on the outside of the second observation hole to prevent microwave leakage at the gap due to the gap between the metal shielding tube 22 and the mesh plate 121. The axial length of the metal shielding tube 22 is larger than the axial length of the mesh hole. The camera 21 shoots the picture inside the cavity from the top perspective through the inner cavity of the metal shielding tube 22 and the second observation hole. There is no need to frequently use the naked eye to observe the cavity, which improves safety and user experience. During the operation of the camera 21, the transmission of microwaves is blocked by the metal shielding tube 22 to prevent the microwaves in the cooking cavity from being reflected to the position of the camera 21 through the second observation hole and interfering with the picture shot by the camera 21.
