Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a heat insulation structure and cooking equipment. Background Art

[0002] The working principle of microwave ovens is slightly different, but whether they use microwaves or heating tubes, they ultimately cook the food by raising its temperature. Therefore, whether the temperature in the cooking cavity meets the set value is a key information that affects the cooking effect.

[0003] When a microwave oven cooking device is working, the temperature in the cooking cavity is relatively high. If a temperature measuring device is directly installed in the cooking cavity, the service life and measurement accuracy of the temperature measuring device will be reduced. In order to solve this problem, some existing microwave oven cooking devices are equipped with infrared temperature measuring devices on the outside, and the temperature in the cooking cavity is measured using infrared remote temperature measurement technology. Specifically, a window is provided on the wall of the cooking device, and a baffle is provided on the window to allow infrared rays to pass through. The infrared temperature measuring device is aligned with the window and measures the temperature in the cooking cavity through the baffle.

[0004] In order to prevent the steam and microwaves in the cooking cavity from leaking out, the baffle is sealed to the side of the window. The defects of this cooking device include: the seal between the baffle and the side of the window cannot completely prevent the steam and microwaves from leaking out, especially after long-term use, the seal may crack, and the infrared temperature measuring device is still at risk of being affected by steam and microwaves; the wall of the cooking device is usually not too thick, and the heat in the cooking cavity may penetrate to the outside of the wall, thereby affecting the infrared temperature measuring device.

[0037] This embodiment discloses a heat insulation structure and a cooking device including the heat insulation structure, wherein the cooking device may be, but is not limited to, a steamer, an oven, a microwave oven, and a device integrating steaming and baking functions. Figures 1 to 3 As shown, the cooking device includes a box body 7 , a viewing window 71 is opened on the box body 7 , the viewing window 71 is sealed and covered with an interlayer 8 , and a heat insulation structure is arranged on the outer side of the box body 7 .

[0038] like Figure 1 , Figure 2 , Figures 5 to 7 As shown, the heat insulation structure includes a shell 3 and a temperature measuring device 1, and the temperature measuring device 1 is arranged outside the shell 3. The shell 3 has a heat insulation cavity (not shown) inside, and the heat insulation cavity has a mounting opening (not shown) for assembly and engagement with the box body 7. The shell 3 also has a first end wall plate 31 arranged opposite to the mounting opening, and the first end wall plate 31 is provided with an opening 33 opening toward the box body 7, and the shell opening 33 opens toward the viewing window 71 (as shown in FIG. Figure 3 as shown) and is located within the range of viewing window 71.

[0039] The temperature measuring device 1 has a temperature measuring probe 11, which is arranged opposite to the opening 33. The temperature measuring probe 11 can measure the temperature inside the box 7 through the opening 33 and the viewing window 71. In this embodiment, the heat insulation structure also includes a hollow mounting base 2, which is fixed to the box 7. The temperature measuring device 1 and the shell 3 are both arranged in the mounting base 2, and the shell 3 is located between the temperature measuring device 1 and the wall of the box 7. In this embodiment, the temperature measuring device 1 is an infrared temperature measuring device, which can remotely measure the temperature inside the box 7 by infrared rays; the interlayer 8 is made of a material with high infrared transmittance, so that "the temperature measuring device 1 located outside the box 7 measures the temperature inside the box 7" can be realized, and at the same time, it can prevent the steam and microwaves in the box 7 from leaking out.

[0040] The housing 3 is arranged between the temperature measuring device 1 and the wall of the box 7, which increases the distance between the temperature measuring device 1 and the box 7, reduces the influence of the high temperature in the box 7 on the measurement accuracy and measurement results of the temperature measuring device 1, improves the control accuracy of the temperature in the box 7, and can automatically adjust the parameters such as power and time required for cooking according to the temperature in the box 7, ensuring that the cooked food is more delicious and nutritious. The housing 3 can prevent high temperature, steam and microwaves from reaching the temperature measuring device 1, avoiding the temperature measuring device 1 from being affected.

[0041] The shell 3 has a shell opening 33, the main purpose of which is to allow infrared rays to pass through. The shell opening 33 can be a common through-hole structure, which is easy to process and will not block or weaken infrared rays; or the through-hole can be covered with a baffle (not shown) made of a material with strong infrared penetration, which can further reduce the influence of the high temperature in the box 7 on the measurement accuracy and measurement results of the temperature measuring device 1, and prevent microwaves from leaking to the location of the temperature measuring device 1. The specific shape and size of the shell opening 33 are not limited, as long as it can provide a sufficiently large temperature measurement space for the temperature measuring probe 11.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the heat insulation structure also includes a heat dissipation duct 4, and a base air inlet hole 23 is opened on the mounting base 2. The heat dissipation duct 4 is connected to the inside of the mounting base 2 through the base air inlet hole 23. The low-temperature airflow for heat dissipation enters the mounting base 2, and can exchange heat with the temperature measuring device 1 and the shell 3, thereby reducing the temperature inside the mounting base 2, ensuring that the temperature measuring device 1 is in a suitable working environment temperature state, with high measurement accuracy, and solving the problem that the high temperature radiation in the box 7 affects the temperature measuring device 1.

[0043] On the basis of the above structure, a base air outlet 21 is provided on the mounting base 2, and the base air outlet 21 and the base air inlet 23 are respectively located on two oppositely arranged side surfaces of the mounting base 2. The housing 3 is located on the air flow path between the base air inlet 23 and the base air outlet 21, and the heat dissipation airflow enters the mounting base 2 through the base air inlet 23 and leaves the mounting base 2 through the base air outlet 21. In this process, the heat dissipation airflow can more fully exchange heat with the temperature measuring device 1 and the housing 3, thereby preventing the temperature measuring device 1 from working in a high temperature environment for a long time, resulting in a decrease in measurement accuracy.

[0044] The specific method of generating the heat dissipation airflow in the heat dissipation air duct 4 is not limited. In this embodiment, the heat insulation structure further includes a heat dissipation fan 9 with a variable frequency boost function. The air outlet of the heat dissipation fan 9 is connected to the heat dissipation air duct 4 to form a heat dissipation airflow in the heat dissipation air duct 4. After the heat dissipation fan 9 is started, the low-temperature air in the environment is continuously sent into the heat dissipation air duct 4, thereby forming a low-temperature heat dissipation airflow.

[0045] It should be noted that Figure 1 and Figure 4 The shape of the heat dissipation duct 4 shown is slightly different, and accordingly, the manner in which the airflow is formed in the heat dissipation duct 4 is also slightly different. Figure 1 In the process, the heat dissipation duct 4 is connected to other heat dissipation structures of the cooking equipment, and the existing heat dissipation airflow is "borrowed" to dissipate heat for the temperature measuring device 1. Only a slight modification of the structure of the existing cooking equipment is required, which is low in cost. Figure 4 In the embodiment, the heat dissipation air duct 4 is relatively short, and a dedicated heat dissipation fan 9 is provided. The air outlet of the heat dissipation fan 9 is connected to the heat insulation cavity to form a heat dissipation airflow in the heat insulation cavity. Specifically, the heat dissipation fan 9 generates a heat dissipation airflow in the heat dissipation air duct 4, and the heat dissipation airflow enters the heat insulation cavity along the heat dissipation air duct 4, with less wind energy loss, good heat dissipation effect, and low noise. Both of the above structures are feasible solutions and will not affect the heat insulation structure and other structures and functions of the cooking device.

[0046] On the basis of the above structure, the thermal insulation structure further includes a swing bracket 5. The temperature measuring device 1 is fixed on the swing bracket 5, and the swing bracket 5 is arranged in the mounting base 2, and the swing bracket 5 can drive the temperature measuring device 1 to swing. Among them, the specific structure of "the swing bracket 5 drives the temperature measuring device 1 to swing" is not limited. In this embodiment, a base card slot 22 is provided on the mounting base 2, and the swing bracket 5 includes a bracket rotating shaft 51, and the bracket rotating shaft 51 is penetrated in the base card slot 22, and the swing bracket 5 can swing around the axis of the bracket rotating shaft 51. The specific method of driving the swing bracket 5 to swing is not limited. In this embodiment, the thermal insulation structure further includes a rotating motor 6, and the rotating output shaft 61 of the rotating motor 6 is connected to the swing bracket 5, and the rotating output shaft 61 can drive the swing bracket 5 to swing around the axis of the bracket rotating shaft 51.

[0047] During the measurement process, the rotating output shaft 61 drives the swing bracket 5 to swing, so that the temperature measuring device 1 can rotate within the set angle, realize the longitudinal three-dimensional temperature detection of the entire area of ​​the box 7, and increase the temperature detection range in the box 7. Even if the user does not place the food in the correct position, the temperature measuring device 1 can still accurately measure the temperature of the food, and then accurately control parameters such as heating power and cooking time, thereby achieving a good cooking effect.

[0048] like Figure 5 and Figure 6 As shown, the first end wall plate 31 is inclined relative to the plane where the installation port is located, which increases the height of the insulation cavity without affecting the normal temperature measurement of the temperature measuring probe 11, and can better block high temperature, steam and microwaves from reaching the temperature measuring device 1, thereby extending the service life of the temperature measuring device 1.

[0049] like Figure 8 As shown, the housing 3 further includes a second end wall plate 32 connected to the first end wall plate 31, and the second end wall plate 32 extends vertically or toward the box body 7 (such as Figure 7 The first end wall plate 31 and the second end wall plate 32 are connected on both sides by the side wall plate 34. The first end wall plate 31, the second end wall plate 32 and the two side wall plates 34 form a heat insulation cavity, which can enclose the box body 7 (as shown in FIG. Figure 1 and Figure 7 The first end wall plate 31 and the second end wall plate 32 can be understood as a flat plate completed from the middle to form a two-slope roof-like structure.

[0050] On the basis of the above structure, a heat dissipation hole 35 is further provided on the shell 3, and the heat dissipation hole 35 is connected with the heat insulation cavity to form a through heat dissipation flow channel for the heat dissipation airflow to pass through. The heat dissipation airflow can contact the shell 3 with a large area, and the heat exchange is more sufficient, which is more conducive to reducing the temperature measuring device 1 (such as Figure 5 The surrounding area is more stable and the measurement result is more accurate.

[0051] The specific location of the heat dissipation holes 35 is not limited. In this embodiment, at least one side wall plate 34 connected to the first end wall plate 31 is provided with a plurality of heat dissipation holes 35, and the heat dissipation channel is connected to the outside of the housing 3 through the heat dissipation holes 35. Figure 5 Cooling airflow (as shown) Figure 5 The heat dissipation (indicated by the straight line with arrows in the middle) will enter the heat dissipation channel between the first end wall plate 31 and the second end wall plate 32 through the heat dissipation holes 35 on one side, and then flow out from the heat dissipation holes 35 on the other side after sufficient heat exchange, isolating the high temperature from the temperature measuring device 1 (such as Figure 5 shown).

[0052] The bottom edges of the first end wall plate 31 , the second end wall plate 32 and / or the side wall plate 34 are bent and extended outward to form a connecting flange 36 . The connecting flange 36 increases the contact area and makes the connecting structure more stable.

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.
