Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a visual cooking device with a heat insulation structure. Background Art

[0002] An air fryer is a kitchen cooking appliance that uses air to "fry". Its main principle is to use high-speed air circulation technology to allow fast-circulating hot air to replace the hot oil in a traditional frying pan to cook the food in the air fryer; at the same time, the hot air it generates can also blow away the moisture on the surface of the food, forming a crispy surface layer on the food, locking the moisture inside the ingredients so that the ingredients in the air fryer can achieve a cooking effect similar to frying.

[0003] In order to facilitate observation of the baking state of food in the pot, the prior art uses a pot made of glass material, and sets the glass pot to an exposed structure, that is, the transparent surface of the glass pot is not blocked.

[0004] For example, the patent with application number CN202222255101.6 discloses an air fryer for a glass with a rotating cage, which includes a pot body and a glass. The pot body includes a placement cabin, and the glass is removably connected in the placement cabin, and a rotating cage is arranged in the glass; limiting side blocks for limiting the glass are arranged on both sides of the interior of the pot body; positioning grooves are arranged on both sides of the inner wall of the glass, and both ends of the rotating cage are embedded and connected in the positioning grooves.

[0005] However, during the cooking process, the surface temperature of the glass pot can reach over 100 degrees Celsius, and users can easily get burned if they accidentally touch the surface of the glass pot. Utility Model Content

[0033] Embodiment 1:

[0034] The present application embodiment discloses a visual cooking device with a heat insulation structure. Figure 1 , including a machine head 1 with a hot air circulation component 11, a transparent pot body 2, a base 3 and a support member 4 for connecting the machine head 1 and the base 3, the machine head 1 covers the transparent pot body 2; the support member 4 is arranged on the rear side of the transparent pot body 2, and a transparent heat-insulating shell 5 is arranged on the outer periphery of the transparent pot body 2 except the rear side, and the transparent heat-insulating shell 5 is rotatably connected to the machine head 1.

[0035] A transparent heat-insulating shell 5 is provided on the periphery of the transparent pot body 2 except for the rear side, forming a large visible area. Together with the transparent pot body 2, the visible range of the cooking device is wide, so as to achieve the visual effect of the cooking device, so that the user can observe the heating status of the food in the transparent pot body 2 on the front side and the left and right sides of the transparent heat-insulating shell 5; at the same time, since the transparent heat-insulating shell 5 is provided, the heat in the transparent pot body 2 can be prevented from directly diffusing outward, thereby avoiding the problem of excessive surface temperature of the equipment due to the visual setting, and can improve energy efficiency and the heating efficiency of the food in the transparent pot body 2.

[0036] In this embodiment, the transparent heat-insulating shell 5 is U-shaped and integrally connected, which has the advantages of simple structure and low cost. The transparent heat-insulating shell 5 can be made of transparent glass, which can meet the visual condition; it can also be made of high-temperature resistant transparent plastic material, which has the advantages of low cost, good structural strength and not easy to break while meeting the visual condition.

[0037] Among them, a rotating member 51 is arranged between the transparent heat-insulating shell 5 and the machine head 1 to facilitate the rotation of the transparent heat-insulating shell 5. When the transparent heat-insulating shell 5 is arranged outside the transparent pot body 2, the opening of the transparent heat-insulating shell 5 faces the rear side, and cooperates with the support member 4 to enclose the transparent pot body 2, which can achieve a visual effect and prevent the heat in the transparent pot body 2 from directly diffusing outward; when the transparent heat-insulating shell 5 rotates upward and is located above the transparent pot body 2, the opening of the transparent heat-insulating shell 5 faces the lower side, and the machine head 1 and the base 3 are open, so as to facilitate the insertion or removal of the transparent pot body 2, thereby facilitating operation.

[0038] It should be noted that the rotating part 51 can be set as a rotating shaft. When the transparent insulation shell 5 is made of transparent glass, the rotating shaft is set on the left and right sides of the machine head 1, and the corresponding position of the transparent insulation shell 5 is provided with an axial hole. The rotating shaft is inserted into the corresponding axial hole, and the transparent insulation shell 5 is rotated around the axial hole through the rotating shaft; when the transparent insulation shell 5 is made of high-temperature resistant transparent plastic, the rotating shaft can be set on the machine head 1, and can also be set on the transparent insulation shell 5.

[0039] In addition, a handle assembly 21 is provided at the front side of the transparent pot body 2, and the handle assembly 21 includes a guard plate 211 provided at the front side of the transparent pot body 2 and a handle 212 provided on the guard plate 211, so as to facilitate the taking and placing of the transparent pot body 2. The transparent heat-insulating shell 5 protrudes outward to form an auxiliary cover body 52, which is covered on the handle assembly 21, and does not affect the rotation of the transparent heat-insulating shell 5, and can facilitate the insertion or removal of the transparent pot body 2.

[0040] In other embodiments, a clearance groove 53 for the handle assembly 21 to pass through is provided on the transparent insulation shell 5, so that the end of the handle assembly 21 is located outside the transparent insulation shell 5, which can reduce the heat conduction between the transparent pot body 2 and the transparent insulation shell 5 to the handle assembly 21. The outside air can also cool down the handle assembly 21, and the user is not easily scalded when holding the handle assembly 21, thereby improving the user's safety.

[0041] When the transparent heat-insulating shell 5 is located outside the transparent pot body 2, there is a gap between the transparent heat-insulating shell 5 and the transparent pot body 2 to form a heat-insulating interlayer 6, thereby avoiding direct contact between the transparent heat-insulating shell 5 and the transparent pot body 2, thereby slowing down the speed at which the heat in the transparent pot body 2 diffuses outward, reducing the probability that the heat diffused outward from the transparent pot body 2 forms water mist on the inner wall of the transparent heat-insulating shell 5, and further improving the visual effect. It should be noted that there is also a gap between the support member 4 and the transparent pot body 2, and it is connected to the heat-insulating interlayer 6.

[0042] The average thickness of the heat insulating interlayer 6 is 3 mm to 25 mm. When the average thickness of the heat insulating interlayer 6 is less than 3 mm, the distance is too close and the heat insulating protection function is not achieved; when the average thickness of the heat insulating interlayer 6 is greater than 25 mm, the distance is too far and it is easy to affect the overall visual effect, and the cost is high during production and installation. Since the gap between the transparent heat insulating shell 5 and the transparent pot body 2 is unevenly distributed, it is necessary to limit the average thickness of the heat insulating interlayer 6.

[0043] In addition, the transparent heat-insulating shell 5 is provided with ventilation holes 7 connecting the heat-insulating interlayer 6 with the outside world, so that the heat-insulating interlayer 6 can be slowly dissipated through the ventilation holes 7, thereby avoiding the problem that the heat in the heat-insulating interlayer 6 cannot be dissipated and the surface temperature of the transparent heat-insulating shell 5 is too high, and preventing the transparent heat-insulating shell 5 from being deformed due to excessive temperature when the heat-insulating transparent plastic material is used.

[0044] Among them, a downwardly opening reflective cover 12 is arranged inside the machine head 1, a motor frame 13 is fixedly arranged above the reflective cover 12, and a sealing silicone ring is also arranged at the opening of the reflective cover 12. When the machine head 1 is covered on the transparent pot body 2, the reflective cover 12 contacts the transparent pot body 2 and seals the transparent pot body 2 through the sealing silicone ring to prevent the heat in the transparent pot body 2 from overflowing from the gap between the reflective cover 12 and the transparent pot body 2. In addition, a connecting portion 121 is formed by horizontally extending from the bottom of the reflective cover 12, and the connecting portion 121 is connected to the machine head 1. Through the setting of the connecting portion 121, the thickness of the heat insulating interlayer 6 reaches the preset requirement, thereby ensuring the overall visual effect and heat insulation protection effect.

[0045] In other embodiments, the motor frame 13 may also be covered on the reflective cover 12 , and the bottom of the motor frame 13 extends horizontally to form a connecting portion 121 connected to the machine head 1 .

[0046] The hot air circulation assembly 11 includes a heating element 111, a fan 112, and a motor 113 for driving the fan 112 to rotate. The motor 113 is arranged on the motor frame 13. The heating element 111 and the fan 112 are located in the reflector 12. A receiving chamber 14 is formed between the motor frame 13 and the top of the head 1 and between the reflector 12 and the head 1. The motor 113 is located in the receiving chamber 14 and is arranged on the motor frame 13. A cold air chamber 15 is formed between the motor frame 13 and the reflector 12. A mounting hole is arranged on the motor frame 13 and at the motor 113 so that the receiving chamber 14 and the cold air chamber 15 are connected.

[0047] A first fan blade 151 is provided in the cold air cavity 15, and the motor shaft of the motor 113 is connected to the first fan blade 151 so as to be able to drive the first fan blade 151 to rotate. A cold air inlet communicating with the accommodating cavity 14 is provided at the top of the machine head 1, and an air outlet 16 communicating with the cold air cavity 15 is provided at the rear side of the machine head 1. Under the action of the rotation of the first fan blade 151, external air is sucked into the cold air cavity 15 through the cold air inlet and discharged through the air outlet 16, which can not only dissipate the heat of the motor 113, but also take away the heat radiated by the reflector 12, thereby reducing the temperature of the machine head 1.

[0048] In addition, a hot air outlet is provided at the rear side of the reflector 12, and the hot air outlet is connected to the air outlet 16. In this embodiment, a baffle is provided at the rear side of the reflector 12, and the baffle is located above the hot air outlet to guide the hot air at the hot air outlet, thereby preventing the hot air from flowing upward into the cold air chamber 15, so that the hot air can be discharged from the air outlet 16.

[0049] The heating element is heated, and the fan 112 rotates to blow the heat generated by the heating element into the transparent pot body 2, heating the food in the transparent pot body 2. Under the back suction effect of the fan 112, the hot air is reflected by the bottom surface of the transparent pot body 2 and flows upward. When the hot air passes through the food, it takes away the moisture and part of the grease on the surface of the food, and is finally sucked into the fan 112, repeating the cycle; during the cycle, a part of the hot air will be discharged through the hot air outlet and the air outlet 16 with the moisture and grease generated by the food. Among them, the hot air discharged from the hot air outlet flows to the air outlet 16, and mixes with the cold air discharged from the cold air chamber 15, which can quickly cool the hot air, so that the hot air with reduced temperature is finally discharged from the air outlet 16, effectively reducing the temperature at the air outlet 16, making the head 1 not easily affected by the hot air, thereby improving the reliability and service life of the overall structure of the head 1, and at the same time can improve the user's safety.

[0050] In the process of heating food, a large amount of hot air will be generated in the heat-insulating interlayer 6, and airflow exchange with the external cold air will be achieved through the ventilation holes 7, thereby achieving the effect of passive heat dissipation.

[0051] Embodiment 2:

[0052] The difference between this embodiment and the embodiment is that: at least two support members 4 are provided, and a transparent heat-insulating back plate 8 is provided between two adjacent support members 4. A complete transparent heat-insulating shell 5 is formed by the transparent heat-insulating shell 5 and the support members 4 at the rear side and the transparent heat-insulating back plate 8, and the transparent pot body 2 is enclosed therein, so that the cooking condition of the food in the transparent pot body 2 can be fully observed from all sides, thereby increasing the visual range and preventing the heat in the transparent pot body 2 from directly diffusing outward.

[0053] Among them, there is a gap between the transparent insulation back plate 8 and the transparent pot body 2, and the gap is connected with the gap between the transparent pot body 2 and the transparent insulation shell 5, together forming an insulation interlayer 6, and the transparent insulation back plate 8 is provided with air holes 81, and the air holes 81 are connected with the insulation interlayer 6. The ventilation holes 7 and the air holes 81 are used to dissipate the heat of the insulation interlayer 6 to avoid the problem of excessive surface temperature of the transparent insulation shell 5 and the transparent insulation back plate 8 due to the inability to dissipate the heat in the insulation interlayer 6.

[0054] It should be noted that the transparent insulation back panel 8 can be made of high-temperature resistant transparent plastic material, and fixedly connected to the support 4 by bolts or other locking parts, or clamped between the two support members 4; the transparent insulation back panel 8 can also be made of transparent glass and inserted between the two support members 4, and high-temperature resistant sealing rubber rings are arranged around the transparent insulation back panel 8 to clamp the transparent insulation back panel 8.

[0055] Embodiment 3:

[0056] The difference between this embodiment and the above-mentioned embodiment is that the air outlet 16 is arranged on the rear side of the head 1, and the heat-insulating interlayer 6 is connected with the cold air chamber 15 and the air outlet 16. Under the action of the first fan blade 151, the external air is sucked into the heat-insulating interlayer 6 through the ventilation holes 7 and the air holes 81, and is discharged outward through the air outlet 16, thereby forming a heat dissipation channel to discharge the heat accumulated in the heat-insulating interlayer 6 to achieve a heat dissipation effect.

[0057] Specifically, a cold air channel is provided on the connection portion 121 , the heat-insulating space is connected with the accommodating cavity 14 through the cold air channel, and the heat-insulating interlayer 6 is connected with the accommodating cavity 14 and the cold air cavity 15 through the cold air channel.

[0058] During the rotation of the first fan blade 151, a part of the air in the cold air chamber 15 is discharged from the air outlet 16, so that a negative pressure space is formed inside. Under the action of the negative pressure, the external air enters the thermal insulation interlayer 6 from the ventilation holes 7 and the air holes 81 to dissipate heat and cool the thermal insulation interlayer 6; then a part of the air enters the accommodating chamber 14 through the cold air channel to cool the motor 113, and is sucked into the cold air chamber 15 under the action of the first fan blade 151, and another part of the air directly enters the cold air chamber 15 through the cold air channel; when the cold air flows in the cold air chamber 15, it can take away the heat radiated from the reflector 12, and is finally discharged through the air outlet 16 to realize the cold air circulation.

[0059] It should be noted that the ventilation holes 7 are arranged at the bottom of the transparent heat-insulating shell 5, the air holes 81 are arranged at the bottom of the transparent heat-insulating back plate 8, and the opening area of ​​the ventilation holes 7 and the air holes 81 is 1%-20% of the overall area of ​​the transparent heat-insulating shell 5 and the transparent heat-insulating back plate 8, so as to improve the heat dissipation effect of the heat-insulating interlayer 6. When the opening area of ​​the ventilation holes 7 and the air holes 81 is too large or not concentrated in the lower part, it is easy to cause the problem that the air flows significantly in the upper part of the heat-insulating interlayer 6, and does not flow or flows less in the lower part, and the heat dissipation effect of the heat-insulating interlayer 6 is not achieved.

[0060] The bottom of the base 3 is also provided with a first air inlet 9, which is connected to the heat-insulating interlayer 6, so that external air can enter the heat-insulating interlayer 6 from the bottom, and cooperate with the external air entering through the ventilation holes 7 and the air holes 81 to more fully cool and dissipate heat for the heat-insulating interlayer 6. It should be noted that the bottom of the base 3 is provided with a foot to support the cooking device and keep the base 3 in a suspended state, thereby ensuring that external air can enter the heat-insulating interlayer 6 through the first air inlet 9.

[0061] The opening areas of the first air inlet 9, the ventilation holes 7 and the air holes 81 are 10%-40% of the areas of the transparent heat-insulating shell 5 and the transparent heat-insulating back plate 8, further improving the overall heat dissipation effect.

[0062] In addition, a second air inlet is provided on the top of the machine head 1 to connect the cold air chamber 15 with the outside, that is, a second air inlet is provided on the top of the machine head 1 to connect with the accommodating chamber 14, so that the external air enters the accommodating chamber 14 through the second air inlet, and enters the cold air chamber 15 through the mounting hole under the action of the first fan blade 151, which can directly dissipate the heat of the motor 113, thereby improving the heat dissipation effect of the motor 113. It should be noted that the opening area of ​​the second air inlet is smaller than the opening area of ​​the ventilation hole 7, which can improve the cooling and heat dissipation effect of the motor 113 without affecting the air intake of the first air inlet 9 and the ventilation hole 7.

[0063] In other embodiments, the support member 4 is hollow to form a cold air space, which is connected to the first air inlet 9 and to the cold air cavity 15 through a cold air channel. External air enters the cold air space through the first air inlet 9, flows to the cold air cavity 15 through the cold air channel, and is finally discharged from the air outlet 16; when the cold air flows through the cold air space, the support member 4 is cooled and dissipated, so that the support member 4 is not easily affected by the hot air, thereby improving the reliability and service life of the overall structure of the support member 4, and at the same time can improve the user's safety.

[0064] Among them, a ventilation hole 7 connecting the cold air space with the outside is arranged on the outer wall of the support member 4. Together with the first air inlet 9, the air flow in the cold air space can be increased to further dissipate the heat of the support member 4.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
