Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cooking device. Background Art

[0002] Many cooking devices need to raise the temperature of food to complete the cooking process, so maintaining the cooking cavity at the set temperature within the set time is a key factor in ensuring the cooking effect. Since the cooking cavity is constantly at a high temperature during the cooking process, it is difficult for ordinary temperature measuring devices to work in the cooking cavity for a long time. Some existing cooking devices use technologies such as infrared temperature measuring devices to achieve remote temperature measurement of the cooking cavity.

[0003] Although the temperature measuring device is outside the inner pot of the cooking device, the high temperature in the cooking cavity will form high temperature radiation to the area around the inner pot. In order to measure the temperature inside through the window opened on the wall of the inner pot, the temperature measuring device cannot be too far away from the inner pot, so the temperature measuring device will inevitably be within the range of high temperature radiation. In order to solve the problem of poor temperature measurement accuracy and short service life of the temperature measuring device caused by the high temperature environment, some existing cooking devices are equipped with air cooling devices for the temperature measuring device. The air cooling device can deliver low-temperature heat dissipation airflow to the temperature measuring device, and perform heat exchange with the temperature measuring device (and its surrounding environment, accessories, etc.) through the heat dissipation airflow, so that the temperature measuring device works at an appropriate temperature state.

[0004] The defects of this cooking device include: during heat exchange, the heat dissipation airflow will hit the temperature measuring device at a certain speed, causing the temperature measuring device to shake to a certain extent, affecting the accuracy of the temperature measurement data; after long-term use, the structure used to support and fix the temperature measuring device is prone to loosening and bending due to frequent shaking, shortening its service life.

[0033] This embodiment discloses a cooking device, which may be, but is not limited to, a steamer, an oven, a microwave oven, and other kitchen appliances with steaming and baking functions. Figures 1 to 3 As shown, the cooking device includes an inner liner 9, a temperature measuring component and a housing 2, wherein the temperature measuring component is assembled in the housing 2. The inner liner 9 has a cooking cavity, and the temperature measuring component includes a temperature measuring device 1 for measuring the temperature in the cooking cavity. A temperature measuring window 91 is provided on the top surface or the side surface of the inner liner 9, and the temperature measuring component is located outside the temperature measuring window 91.

[0034] The temperature measuring device 1 may be, but is not limited to, an infrared temperature measuring device, which can measure the temperature in the cooking cavity through the temperature measuring window 91 and automatically adjust the cooking power and cooking time according to the measured temperature value. The temperature measuring window 91 includes a through hole (not shown) opened on the top surface or side of the cooking device and a baffle (not shown) sealed and covered at the through hole. The baffle is made of a material with strong penetrability of the test light (such as infrared rays). The temperature measuring device 1 can remotely measure the temperature in the cooking cavity through the temperature measuring window 91. The baffle prevents the steam and microwaves in the cooking cavity from leaking out without affecting the normal temperature measurement, which can weaken the high temperature radiation to a certain extent, reduce the influence of the high temperature in the cooking cavity on the temperature measuring device 1, and improve the accuracy of temperature measurement.

[0035] like Figure 2 , Figures 4 to 6 As shown, the housing 2 is mounted on the upper edge of the inner container 9, and the housing 2 has a base 4. The base 4 has a flange 3 extending downward at the side adjacent to the side wall of the inner container 9. When the housing 2 and the inner container 9 are in an assembled state, the flange 3 abuts against the side wall of the inner container 9. That is, the flange 3 and the base 4 form an L-shaped structure.

[0036] The housing 2 has a mounting body, the interior of which is hollow to form a chamber for assembling the temperature measuring device 1. The housing 2 can protect the temperature measuring device 1, prevent the high temperature radiation of the cooking cavity from affecting the temperature measurement result, and extend the service life of the temperature measuring device 1. The base 4 fits the top surface of the inner pot 9, and the flange 3 fits the side of the inner pot 9. The housing 2 is connected to the inner pot 9 through two mutually perpendicular side surfaces, with accurate positioning and high installation efficiency; the assembly structure is firm, and the housing 2 is not easy to shake, so as to avoid affecting the accurate measurement of the temperature in the cooking cavity by the temperature measuring device 1 due to shaking; even if the housing 2 shakes to a certain extent, it will not cause the housing 2 to separate from the inner pot 9, and it is safer to use.

[0037] The specific processing method of the base 4 is not limited. In this embodiment, the base 4 is a sheet plate, and a part of the sheet plate is bent relative to another part by stamping on the sheet plate, thereby obtaining the flange 3 and the base 4 bent into an L-shaped structure. The processing method is simple, low in cost, and high in processing efficiency. The connection between the flange 3 and the base 4 is high in strength, can withstand a large impact force, and has a long service life.

[0038] The base 4 includes a first step portion 41 and a second step portion 42, and the mounting body of the housing 2 is arranged on the second step portion 42. The first step portion 41 and the second step portion 42 are arranged in sequence from the middle of the top wall of the inner liner 9 to its side wall to adapt to the edge rib wall of the inner liner 9, so that the bottom surface of the base 4 can fit the top wall of the inner liner 9 more closely, and the connection is more secure. The flange 3 is formed on the outside of the second step 42. In this embodiment, the flange 3 and the second step portion 42 have an arc transition, and the flange 3 and the second step portion 42 are not easily deformed or broken, and have a long service life.

[0039] On the basis of the above structure, the temperature measuring assembly further includes a box-shaped mounting frame 5, and the temperature measuring device 1 is detachably arranged on the mounting frame 5. The mounting frame 5 is provided with a frame rotating shaft 51 on two oppositely arranged side edges, that is, the mounting frame 5 is provided with two frame rotating shafts 51 on an opposite basis. The frame rotating shaft 51 is connected to the housing 2, and the mounting frame 5 can rotate around the axis of the frame rotating shaft 51. The temperature measuring device 1 can rotate (swing) synchronously with the mounting frame 5, increase the temperature measuring range, and realize vertical three-dimensional scanning and temperature measurement in the cooking chamber. Even if the user does not place the food to be cooked at the set position, the temperature measuring device 1 can scan the temperature of the food to be cooked, and the measurement result is more accurate. The cooking power and cooking time can be adjusted according to the temperature of the food to be cooked, and the cooking effect is better.

[0040] The specific method for realizing the rotation of the temperature measuring device 1 and the mounting frame 5 is not limited. In this embodiment, the cooking device further includes a motor 8, and the output shaft 81 of the motor 8 is connected to the frame rotating shaft 51. After the motor 8 is started, the output shaft 81 rotates, and the frame rotating shaft 51 rotates synchronously under the drive of the output shaft 81; the mounting frame 5 and the frame rotating shaft 51 are an integral structure, and the mounting frame 5 can be rotated (swinged) when the frame rotating shaft 51 rotates. The specific structure of the motor 8 is not limited, and any motor 8 in the prior art that can rotate the output shaft 81 around its own axis can be used.

[0041] An avoidance notch 31 is provided on the flange 3, and the motor 8 is embedded in the avoidance notch 31, which saves space and is conducive to reducing the volume of the cooking device; the avoidance notch 31 can play a positioning role for the motor 8, and the installation efficiency is high; the avoidance notch 31 can also play a limiting role for the motor 8, avoiding distance jitter when the motor 8 is working, reducing the noise of the cooking device, and providing a good user experience.

[0042] On the basis of the above structure, the cooking device further includes a damper 7, which includes a barrel-shaped body (not shown) and a telescopic rod 71 passing through the barrel-shaped body. A frame damping hinge seat 52 is provided on the mounting frame 5, and a damping hinge seat 25 is provided on the housing 2. One of the damper 7 and the telescopic rod 71 is hinged to the frame damping hinge seat 52 through a hinge (not shown), and the other of the damper 7 and the telescopic rod 71 is hinged to the damping hinge seat 25 through a hinge.

[0043] The telescopic rod 71 can extend or retract the barrel-shaped body at a relatively slow speed, ensuring that the mounting frame 5 will not get stuck during rotation, making the spatial posture of the mounting frame 5 more stable and not vibrating due to the cooling airflow, thereby avoiding affecting the accuracy of temperature measurement.

[0044] In order to quickly reduce the temperature of the temperature measuring device 1 and its surrounding environment, the cooking device also includes a heat dissipation component. Figure 1 As shown, the heat dissipation component includes a heat dissipation duct 6; Figure 7 As shown, the shell 2 is provided with an air inlet 23 and an air outlet 24. For more complete heat exchange, the air inlet 23 and the air outlet 24 are respectively located on two oppositely arranged side surfaces, and the temperature measuring device 1 is located between the air inlet 23 and the air outlet 24. The specific shapes of the air inlet 23 and the air outlet 24 are not limited. In this embodiment, the air inlet 23 is a through hole with a large area, a large air intake, and convenient processing; the air outlet 24 is composed of a plurality of through holes with smaller areas, and the area of ​​the air outlet 24 is smaller than that of the air inlet 23. Therefore, the flow rate of the airflow at the air outlet 24 is greater than the flow rate at the air inlet 23, and a negative pressure can be formed at the air outlet 24, which helps the gas in the shell 2 to flow out quickly and improve the heat exchange efficiency.

[0045] The low-temperature heat dissipation airflow enters the inner cavity of the housing 2 through the heat dissipation air duct 6 and the air inlet 23, exchanges heat with the temperature measuring device 1 and its surroundings, and then flows out of the housing 2 through the air outlet 24. After the heat exchange, the temperature of the temperature measuring device 1 and its surroundings drops rapidly, solving the problem of the decrease in the measurement accuracy of the temperature measuring device 1 due to the high-temperature radiation in the cooking cavity.

[0046] The specific method for allowing the low-temperature air in the environment to enter the heat dissipation air duct 6 to form a heat dissipation airflow is not limited. A special heat dissipation fan (not shown) with a variable frequency boost function can be set at the air inlet end of the heat dissipation air duct 6. After the heat dissipation fan is started, the low-temperature air in the surrounding environment can be pumped into the heat dissipation air duct 6 to form a low-temperature heat dissipation airflow. The air inlet end of the heat dissipation air duct 6 can also be connected to an existing air duct of the cooking device (for example, an air duct for cooling the magnetron). When the existing heat dissipation fan is working, a part of the low-temperature heat dissipation airflow generated will enter the heat dissipation air duct 6 for heat exchange with the temperature measuring device 1 and its surrounding environment. There is no need to set up two heat dissipation fans separately, which reduces costs and reduces noise.

[0047] The specific structure of the housing 2 is not limited, as long as it can accommodate the temperature measuring device 1 and the mounting frame 5 and can support the mounting frame 5 to be suspended. Figure 4 As shown, mounting holes 21 are respectively provided on two oppositely disposed side surfaces of the housing 2, and the frame rotating shaft 51 is passed through the mounting holes 21. The frame rotating shaft 51 is clearance-matched with the mounting hole 21, and the mounting hole 21 can limit the radial movement of the frame rotating shaft 51, and will not hinder the frame rotating shaft 51 from rotating around its own axis. The temperature measuring device 1 can scan and measure the temperature in the cooking cavity over a large range, and can adjust the cooking power and cooking time according to the temperature of the food to be cooked, so that the taste of the cooked food is better.

[0048] The mounting hole 21 may be a through-hole structure, which can limit the frame rotating shaft 51 from the four directions of top, bottom, left and right, ensuring that the frame rotating shaft 51 does not move in the radial direction, and the structure is more stable, but the mounting frame 5 is more complicated to disassemble and assemble, and at least one frame rotating shaft 51 cannot form an integral structure with the mounting frame 5. That is, at least one frame rotating shaft 51 and the mounting frame 5 are separate structures, and the mounting frame 5 is first placed in the housing 2 and aligned with the mounting hole 21, and then the separate frame rotating shaft 51 is connected to the mounting frame 5 by screwing or the like.

[0049] In order to simplify the disassembly and assembly of the mounting frame 5, as Figures 5 to 7As shown, a guide groove 22 is provided on the side of the shell 2, and the avoidance notch 31 is arranged opposite to the guide groove 22 located on the outside of the installation body. Specifically, the installation body of the shell 2 is provided with a guide groove 22 with an upward opening on the inner side adjacent to the middle of the top wall of the inner liner 9 and the outer side adjacent to the flange 3, and the temperature measuring device 1 can be assembled in the installation body from the guide groove 22. Each guide groove 22 extends from the edge of the side to the corresponding installation hole 21. During installation, the frame rotating shaft 51 is aligned with the guide groove 22 and then pressed down. The frame rotating shaft 51 moves down along the guide groove 22 until it is stuck in the bottom installation hole 21, completing the installation of the mounting frame 5. Under the action of its own weight, the mounting frame 5 and the temperature measuring device 1 will not easily jump up from the guide groove 22, which can meet the requirement of stable temperature measurement of the temperature measuring device 1.

[0050] When there are very strict requirements on the vertical position of the temperature measuring device 1, the diameter of each mounting hole 21 can be made larger than the bottom width of the corresponding guide groove 22, that is, a stopper (not shown) is formed between the bottom of the guide groove 22 and the mounting hole 21. During installation, the frame rotating shaft 51 is pressed hard, and the frame rotating shaft 51 squeezes the stopper to both sides; the bottom of the guide groove 22 and the stopper undergo a certain degree of elastic deformation, and the frame rotating shaft 51 passes through the stopper and enters the mounting hole 21, and the bottom of the guide groove 22 and the stopper are reset. The stopper abuts against the frame rotating shaft 51 from above to prevent the mounting frame 5 and the temperature measuring device 1 from moving upward.

[0051] On the basis of the above structure, there is a height difference between the two wall panels where the two mounting holes 21 are respectively located, so that the opening on the top of the installation body for assembling the temperature measuring device 1 is inclined relative to the base 4. When installing the temperature measuring device 1, the installer stands on the side where the lower wall panel is located, and only needs to lift the temperature measuring device 1 to a position slightly higher than the wall panel to put the temperature measuring device 1 into the installation body through the opening, which saves time and effort and is convenient for installation.

[0052] Note that the above are only preferred embodiments of the present invention and the technical principles used. 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.
