Technical Field

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

[0002] A cooking device with a microwave oven function can cook by raising the temperature of food. The main factors affecting the cooking effect include whether the temperature in the cooking cavity meets the set value and whether the duration of the temperature meets the set value. Therefore, the cooking device needs to be equipped with a temperature measuring device to measure the temperature value in the cooking cavity.

[0003] When the cooking device is working, the cooking cavity is constantly in a high temperature state, and the temperature measuring device is usually difficult to work normally in this high temperature environment. In order to solve this problem, some existing cooking devices are equipped with an infrared thermometer, and a light-transmitting hole that allows infrared rays to penetrate is opened on the side wall of the inner pot of the cooking device. The infrared thermometer is aligned with the light-transmitting hole, and the temperature in the cooking cavity can be remotely measured through the light-transmitting hole.

[0004] The defects of this temperature measurement structure include: in order to avoid leakage of high temperature, microwaves, etc. in the cooking cavity, the area of ​​the light-transmitting port cannot be too large, resulting in the temperature measurement angle of the temperature measuring device being limited, and only the temperature value in a smaller range in the cooking cavity can be measured. Once the food to be cooked is placed in a relatively biased position, the temperature measuring device may not be able to measure the temperature of the food to be cooked. Utility Model Content

[0033] This embodiment discloses a cooking device, which may be, but is not limited to, a steamer, an oven, a microwave oven, or other kitchen appliances with both steaming and baking functions. Figure 1 ,to Figure 5As shown, the cooking device includes an inner pot 4, a temperature measuring device 1 and a support 3. The inner pot 4 has a cooking cavity 42. The inner pot 4 also has a light-transmitting opening 41 that penetrates along the thickness direction of its wall plate. Specifically, the light-transmitting opening 41 is located on the top surface and at the junction of the top surface and the side surface. The temperature measuring device 1 is arranged outside the inner pot 4 and on the light propagation path of the light-transmitting opening 41, and measures the temperature in the cooking cavity 42 through the light-transmitting opening 41.

[0034] In order to prevent the high-temperature steam and microwaves in the cooking cavity 42 from leaking out, the light-transmitting port 41 is sealed and covered with a light-transmitting plate (not shown) that allows infrared rays and other objects required for temperature measurement to pass through. This prevents the high-temperature steam and microwaves in the cooking cavity 42 from leaking out through the light-transmitting port 41 without affecting the remote temperature measurement, and prevents the high-temperature steam and microwaves from affecting the normal operation of the temperature measuring device 1. The temperature measurement result is more accurate, and the service life of the temperature measuring device 1 is extended.

[0035] The support member 3 is disposed outside the inner pot 4 and has a mounting groove 36 for assembling the temperature measuring device 1. The mounting groove 36 is vertically penetrated and arranged obliquely from top to bottom toward the inner pot 4 so that the lower end opening is opposite to the light-transmitting opening 41. In this embodiment, the lower end opening area of ​​the mounting groove 36 is larger than the light-transmitting opening 41 and surrounds the outer periphery of the light-transmitting opening 41, making full use of the area of ​​the light-transmitting opening 41 to measure the temperature of the space in the inner pot 4 as much as possible. In view of the fact that the food to be cooked is usually placed near the center of the inner pot 4, the mounting groove 36 is arranged obliquely toward the center of the inner pot 4, so that the temperature measuring device 1 can more accurately measure the temperature of the location of the food to be cooked.

[0036] The specific installation structure of the temperature measuring device 1 and the support member 3 is not limited. In this embodiment, the cooking device further includes a housing 2, the temperature measuring device 1 is detachably connected to the housing 2, and the integral structure composed of the temperature measuring device 1 and the housing 2 is arranged in the inner cavity of the support member 3. After installation, the temperature measuring device 1 is arranged tilted relative to the light transmission port 41. Among them, the temperature measuring device 1 can be, but is not limited to, an infrared temperature measuring instrument.

[0037] In this embodiment, the support member 3 is arranged obliquely as a whole, and its extension direction is consistent with the internal installation groove 36. The upper end of the support member 3 has an installation opening for the temperature measuring device 1 to be placed in the installation groove 36. That is, the wall surface of the support member 3 is a flat plate-like structure, and the outer shape of the support member 3 is basically the same as the shape of the installation groove 36, and the size is only different from the thickness of the wall surface, and the processing difficulty is low.

[0038] On the basis of the above structure, the plane where the installation opening is located intersects with the plane where the lower end opening of the support member 3 is located, that is, the plane where the installation opening is located is inclined relative to the plane where the lower end opening of the support member 3 is located, and one side of the installation groove 36 is lower than the other side. When the heat dissipation gas flows in the installation groove 36, the heat dissipation gas tends to flow from the lower side to the higher side, forming a turbulent flow, and the heat dissipation effect is better.

[0039] The temperature measuring device 1 can measure the temperature in the cooking cavity 42 from the outside of the cooking cavity 42. The mounting groove 36 is vertically penetrated and arranged from top to bottom in a tilted manner toward the inner pot 4. Therefore, the temperature measuring device 1 can be arranged from top to bottom in a tilted manner toward the inner pot 4. Figure 5 The area indicated by the middle cross pattern is the temperature measurement range. That is, the temperature measurement range of the tilted temperature measuring device 1 is a right triangle, which can ensure that the side where the temperature measuring device 1 is located and the bottom surface of the entire cooking cavity 42 are within the temperature measurement coverage range, and the temperature measurement blind area only appears on the opposite side and the top surface of the cooking cavity 42. The food to be cooked is basically placed on the bottom surface of the cooking cavity 42, and the height usually does not reach the top surface of the cooking cavity 42, so the temperature measurement range of the tilted temperature measuring device 1 can basically cover the food to be cooked, and the cooking power and cooking time can be adjusted according to the temperature of the food to be cooked, so that the cooking effect is better.

[0040] The temperature measuring device 1 is tilted and arranged at the side of the cooking cavity 42, without enlarging the light-transmitting opening 41 (such as Figure 2 Under the premise of the area shown in the figure, the irradiation range of the infrared ray is increased, thereby increasing the temperature measurement range of the temperature measuring device 1, and preventing the food to be cooked from being outside the temperature measurement range.

[0041] The specific structure for realizing "the temperature measuring device 1 is tilted" is not limited. In this embodiment, the housing 2 is a box-shaped structure with an open top surface, the temperature measuring device 1 is placed in the housing 2, and the bottom surface of the temperature measuring device 1 fits the bottom of the housing 2. That is, the temperature measuring device 1 is parallel to the housing 2. The tilted setting of the temperature measuring device 1 can be realized by connecting the housing 2 to the support 3 at an angle. The structure is simple and easy to process, and convenient to disassemble and assemble.

[0042] The specific structure of “the housing 2 is obliquely connected to the support member 3” is not limited. In this embodiment, Figure 6 As shown, a low hinge hole 31 and a high hinge hole 32 are respectively provided on two oppositely disposed side surfaces of the support member 3, and the position of the high hinge hole 32 is higher than the position of the low hinge hole 31. Two hinge shafts 21 are provided on the housing member 2, one hinge shaft 21 is passed through the low hinge hole 31, and the other hinge shaft 21 is passed through the high hinge hole 32. After installation, one hinge shaft 21 is at a high position and the other hinge shaft 21 is at a low position, so that the housing 2 is in an inclined state.

[0043] like Figure 3 , Figure 6 and Figure 7As shown, the outer side of the lower end of the support member 3 also has a first connecting edge 37 extending laterally, and the outer periphery of the isolation cover 5 has a second connecting edge 55 corresponding to the first connecting edge 37. When the support member 3, the isolation cover 5 and the inner liner 4 are in an assembled state, the second connecting edge 55 is located between the first connecting edge 37 and the upper wall plate of the inner liner 4, and the connection structure is more stable, avoiding the support member 3 and the isolation cover 5 from shaking under the impact of the heat dissipation airflow, and the noise is small.

[0044] In order to further improve the installation stability of the isolation cover 5 , a limiting groove (not shown) is provided on the periphery of the light-transmitting opening 41 , and the second connecting edge 55 is clamped in the limiting groove.

[0045] On the basis of the above structure, the cooking device further includes an isolation cover 5, which is located in the inner cavity of the support member 3 and below the temperature measuring device 1, and the upper end of the isolation cover 5 is located in the mounting groove 36, so that a gap is left between the temperature measuring device 1 and the light-transmitting port 41. That is, the isolation cover 5 is arranged between the support member 3 and the light-transmitting port 41 to prevent heat from being transferred to the temperature measuring device 1. Figure 3 , Figure 4 and Figure 7 As shown, the isolation cover 5 includes a first slope 51, a second slope 52 and two side surfaces 54, one side surface 54 is connected between the first slope 51 and the second slope 52 from the left side, and the other side surface 54 is connected between the first slope 51 and the second slope 52 from the right side, thereby forming a roof-like structure with a double slope.

[0046] The roof-like structure can also be called a cover structure with an opening on the bottom surface, which covers the top and the surrounding of the light-transmitting opening 41 and can further prevent the cooking cavity 42 (such as Figure 5 The steam, microwaves, etc. in the temperature measuring device 1 are leaked toward the location of the temperature measuring device 1, and the influence of heat radiation on the temperature measuring device 1 can be reduced.

[0047] An isolation cover detection port 53 is provided on the first inclined surface 51, and the isolation cover detection port 53 is located between the temperature measuring device 1 and the light-transmitting port 41. Infrared rays and other substances required for temperature measurement can pass through the isolation cover detection port 53 and the light-transmitting port 41 to achieve remote temperature measurement. The isolation cover detection port 53 can be sealed and covered with a baffle (not shown), which is made of a material with high infrared transmittance, so as to ensure the accuracy of temperature measurement while preventing steam and microwaves in the cooking cavity 42 from affecting the temperature measuring device 1, reduce the influence of thermal radiation on the temperature measuring device 1, and extend the service life of the temperature measuring device 1.

[0048] Thermal radiation has a certain penetrating ability and cannot be completely isolated. In order to keep the temperature measuring device 1 in an ambient temperature suitable for working, Figure 1 and Figure 7As shown, an air duct 7 is provided on the outer side of the inner tank 4, and a heat dissipation air inlet 34 and a heat dissipation air outlet 35 are provided on the support member 3. The air duct 7 is connected to the interior of the support member 3 through the heat dissipation air inlet 34. A variable frequency booster fan or other device can be used to pump low-temperature air into the air duct 7. After the low-temperature air enters the support member 3, it exchanges heat with the temperature measuring device 1, and the air carrying high temperature is discharged from the heat dissipation air outlet 35, so that the temperature measuring device 1 is cooled.

[0049] Heat dissipation ventilation holes (not shown) are provided on both side surfaces 54 of the isolation cover 5. A portion of the low-temperature air entering the support member 3 will enter between the isolation cover 5 and the light-transmitting port 41 from the heat dissipation ventilation holes on the windward side, and then flow out from the heat dissipation ventilation holes on the other side carrying part of the heat between the isolation cover 5 and the light-transmitting port 41, thereby reducing the heat in the space enclosed by the isolation cover 5 and the light-transmitting port 41, further reducing the influence of thermal radiation on the temperature measuring device 1, and improving the accuracy of temperature measurement.

[0050] Based on the above structure, Figure 3 and Figure 4 As shown, the drive motor 6 is also included. The output shaft 61 of the drive motor 6 is connected to the hinge shaft 21 of the housing 2. When the output shaft 61 rotates around its own axis, it can drive the hinge shaft 21 to rotate synchronously, thereby driving the temperature measuring device 1 to rotate, so as to achieve the cooking cavity 42 (such as Figure 5 The temperature measurement range is wider. When the user does not place the food to be cooked in the set position, the temperature measuring device 1 can still scan the food to be cooked, and can determine the cooking frequency and cooking time according to the temperature of the food to be cooked, ensuring that the cooked food is more delicious.

[0051] In order to adapt to the structural characteristics of the inclined setting of the housing 2, the output shaft 61 is also inclined relative to the light-transmitting opening 41 of the cooking device. In order to save installation space and reduce the volume of the support member 3, as shown in FIG. Figure 6 As shown, a motor avoidance groove 33 is provided on the support member 3, and the drive motor 6 is stuck in the motor avoidance groove 33. In addition, the motor avoidance groove 33 can also limit and fix the drive motor 6, thereby improving the installation efficiency of the drive motor 6 and the stability of the structure.

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.
