Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a steam air fryer with good heat dissipation. Background Technology

[0002] As people's living standards improve, the oil-free cooking method of air fryers is becoming increasingly popular. In most existing steam air fryers, the cooling fan and the heat circulation fan are driven by the same motor. During steam cooking, to prevent excessive exhaust of high-temperature steam from the cooking chamber, the heat circulation fan and the motor are usually stopped. While stopping the heat circulation fan and motor reduces the exhaust of high-temperature steam, it also stops the cooling fan, preventing proper heat dissipation from the air fryer. The heat generated by the steam generation system and excess heat in the cooking chamber cannot be dissipated in time, easily leading to excessively high internal temperatures, affecting the normal operation of other electrical components, and also causing excessively high surface temperatures, potentially resulting in burns to the user. This results in poor user safety and a subpar user experience. Utility Model Content

[0003] This application provides a steam air fryer with good heat dissipation to solve the technical problem that the cooling fan of existing steam air fryers cannot dissipate heat from the machine body during steam cooking, resulting in a poor user experience.

[0004] To address the aforementioned technical problems, this utility model provides a steam air fryer with excellent heat dissipation, comprising a body and a cooking chamber within the body. The body has a water tank with a liquid storage chamber. The body contains a steam generating system connecting the water tank and the cooking chamber. The body also contains a hot air circulation system connected to the cooking chamber and a heat dissipation chamber located outside the cooking chamber and open to the atmosphere. The heat dissipation chamber contains a heat dissipation component, a cold air component, and a drive system. The drive system includes a first drive system and a second drive system. The first drive system is adapted to extend and drive the heat dissipation component and the hot air circulation system. The second drive system is drive-connected to the cold air component. By incorporating the cold air component and the second drive system connected to it within the body, heat dissipation can continue even when the first drive system and the heat dissipation component are not operating. This effectively reduces problems caused by excessively high temperatures within and / or on the surface of the body, improving the performance stability, safety, and user experience of the steam air fryer.

[0005] In an optional embodiment, the machine body is provided with a control system, which includes a first control unit and a second control unit. The first control unit and the second control unit are adapted to be electrically connected to the first drive system and the second drive system, respectively, to control the first drive system and the second drive system to operate independently. By setting the first control unit and the second control unit in the machine body to control the first drive system and the second drive system to operate independently, mutual interference between the first drive system and the second drive system during operation can be avoided, effectively improving the performance stability of the steam air fryer.

[0006] In one optional embodiment, the second drive system includes a second drive motor, which is a speed-regulating motor. The housing contains a temperature sensor that extends at least partially into the heat dissipation cavity and is electrically connected to the control system. The second control unit is configured to: control the second drive motor to increase its speed when the temperature sensor detects that the temperature inside the heat dissipation cavity is greater than a preset temperature; and control the second drive motor to decrease its speed when the temperature sensor detects that the temperature inside the heat dissipation cavity is less than the preset temperature. By setting the second drive motor as a speed-regulating motor and incorporating the temperature sensor extending into the heat dissipation cavity and electrically connected to the control system, the speed of the second drive motor can be adjusted according to temperature changes within the heat dissipation cavity during steam cooking, thereby reducing energy consumption while ensuring effective heat dissipation and significantly improving the user experience.

[0007] In an optional embodiment, the first drive system includes a first drive motor, and the second drive system includes a second drive motor. The first control unit is configured to: control the first drive motor to stop operating when the steam generating system is running; and the second control unit is configured to: control the second drive motor to operate when the steam generating system is running. When the steam air fryer is steam cooking, controlling the first drive motor to stop operating through the first control unit and controlling the second drive motor to operate through the second control unit not only reduces the discharge of high-temperature steam from the cooking chamber but also achieves heat dissipation for the machine body. Simultaneously, controlling the first drive motor to stop operating through the first control unit and controlling the second drive motor to operate through the second control unit also avoids the first drive motor affecting the operation of the second drive motor, effectively ensuring the heat dissipation effect and performance stability of the steam air fryer.

[0008] In an optional embodiment, the body is provided with a vent communicating with the atmosphere and the heat dissipation cavity, and the cooling air assembly is adapted to be disposed adjacent to the first vent. By disposing the cooling air assembly adjacent to the first vent, external cold air can be better drawn into the heat dissipation cavity to dissipate heat from the body; or, hot air inside the body can be better exhausted, effectively improving the heat dissipation efficiency and effect of the body.

[0009] In one optional embodiment, the machine body is provided with an air outlet assembly, which has an air outlet channel. One end of the air outlet channel is connected to the cooking cavity, and the other end is provided with a second vent connecting to the atmosphere. By providing the air outlet assembly in the machine body, excess water vapor in the cooking cavity can be discharged, thus preventing water vapor from accumulating and forming condensation, which would affect the cooking effect of the food.

[0010] In an optional embodiment, the second vent is adapted to be located on the rear side of the unit body, with the first vent positioned above the second vent. By placing the second vent on the rear side of the unit body and the first vent above it, not only can the first and second vents be concealed to improve the overall aesthetics of the air fryer, but the cooling airflow from the first vent can also dissipate heat from the circulating airflow from the second vent, reducing the risk of burns to the user due to excessively high temperatures on the rear side of the unit body, thus effectively improving the safety of the air fryer.

[0011] In one optional embodiment, the cooling air assembly includes a cooling fan, which is adapted to have a spiral blade structure. By setting the cooling fan to a spiral blade structure, not only can unidirectional air intake or exhaust be achieved, effectively improving air intake or exhaust efficiency and thus improving heat dissipation efficiency, but the air intake or exhaust volume can also be increased, thereby improving the heat dissipation effect of the unit.

[0012] In an optional embodiment, the heat dissipation cavity is adapted to surround at least a portion of the cooking cavity. By arranging the heat dissipation cavity around the cooking cavity, the cooling airflow within the heat dissipation cavity can be better utilized to dissipate heat from the cooking cavity, thereby reducing the transfer of high temperatures from the cooking cavity to the outside, which could cause the body temperature to become too high and / or damage to electrical components, effectively ensuring the performance stability and safety of the steam air fryer.

[0013] In an optional embodiment, the steam generating system includes a steam generating component for converting water into steam, and the cooling air component is adapted to be positioned adjacent to the steam generating component. By positioning the cooling air component adjacent to the steam generating component, better heat dissipation from the steam generating component can be achieved during steam cooking, thus preventing overheating and damage to the steam generating component, effectively improving its performance stability and safety. Furthermore, it reduces the outward transfer of high temperatures generated by the steam generating component, preventing overheating of the machine body and / or damage to other electrical components, effectively ensuring the performance stability of the steam air fryer.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application, by setting the cooling air component and the second drive system connected to the cooling air component in the body, enables the second drive motor and the cooling air component to dissipate heat from the body even when the first drive motor and the heat dissipation component are not running. This effectively avoids problems caused by excessively high temperatures inside and / or on the surface of the body, and improves the performance stability, safety, and user experience of the steam air fryer.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] Appendix Figure 1 To be continued Figure 2 The diagram shows a steam air fryer with good heat dissipation provided by this utility model. The steam air fryer includes a body 10, a cooking chamber 11 with an open front side inside the body 10, and a hot air circulation system 20 communicating with the cooking chamber 11. The hot air circulation system 20 is adapted to generate circulating heat flow and introduce it into the cooking chamber 11 to cook the food inside the cooking chamber 11. By setting the hot air circulation system 20 in the steam air fryer, air frying cooking can be realized, effectively improving the functionality and applicability of the steam air fryer.

[0025] like Figure 1 and Figure 2 As shown, the body 10 is provided with a water tank 30 having a liquid storage chamber. The body 10 is provided with a steam generating system 40 that connects the water tank 30 and the cooking chamber 11. The steam generating system 40 is adapted to convert the water in the water tank 30 into high-temperature steam and introduce it into the cooking chamber 11 to steam cook the food in the cooking chamber 11.

[0026] like Figure 2As shown, the cooking cavity 11 has a heat dissipation cavity 12 connected to the atmosphere on its outer side. The heat dissipation cavity 12 is provided with a heat dissipation component 50, a cold air component 60 and a drive system 70 for generating heat dissipation and cold air flow. The drive system 70 includes a first drive system 71 and a second drive system 72. The first drive system 71 is adapted to extend and drive to connect with the heat dissipation component 50 and the hot air circulation system 20. The second drive system 72 is adapted to drive to connect with the cold air component 60. By incorporating the cooling air assembly 60 and the second drive system 72 connected to the cooling air assembly 60 within the body 10, heat dissipation of the body 10 can still be achieved through the second drive system 72 and the cooling air assembly 60 even when the first drive system 71 and the heat dissipation assembly 50 are not in operation. This not only effectively reduces the risk of damage to the control circuit, drive system 70, and other electrical components within the body 10 due to excessively high internal temperature, but also reduces the likelihood of burns to the user due to excessively high surface temperature of the body 10. This effectively improves the performance stability, safety, and user experience of the steam air fryer.

[0027] In an optional embodiment, the body 10 is provided with a control system 80, which includes a first control unit and a second control unit. The first control unit and the second control unit are adapted to be electrically connected to the first drive system 71 and the second drive system 72, respectively, to control the independent operation of the first drive system 71 and the second drive system 72. By setting the first control unit and the second control unit in the body 10 to control the independent operation of the first drive system 71 and the second drive system 72, mutual interference between the first drive system 71 and the second drive system 72 during operation can be avoided, effectively improving the performance stability of the steam air fryer.

[0028] As shown in Figure 2, the second drive system 72 includes a second drive motor 721, which is preferably a variable-speed motor. A temperature sensor 90, extending at least partially into the heat dissipation cavity 12 and electrically connected to the control system 80, is provided within the body 10. The second control unit is adapted to control the second drive motor 721 to increase its speed when the temperature sensor 90 detects that the temperature inside the heat dissipation cavity 12 is greater than a preset temperature; and to control the second drive motor 721 to decrease its speed when the temperature sensor 90 detects that the temperature inside the heat dissipation cavity 12 is less than the preset temperature. By setting the second drive motor 721 as a variable-speed motor and providing the temperature sensor 90 extending into the heat dissipation cavity 12 and electrically connected to the control system 80 within the body 10, the speed of the second drive motor 721 can be adjusted according to the temperature change within the heat dissipation cavity 12 during steam cooking in the air fryer. This reduces energy consumption while ensuring effective heat dissipation, thereby reducing user operating costs and effectively improving the user experience.

[0029] like Figure 2 As shown, in an optional embodiment, the first drive system 71 includes a first drive motor 711, and the second drive system 72 includes a second drive motor 721. The first control unit is adapted to control the first drive motor 711 to stop running when the steam generating system 40 is running; the second control unit is adapted to control the second drive motor 721 to run when the steam generating system 40 is running. When the steam air fryer is steam cooking, controlling the first drive motor 711 to stop running through the first control unit and controlling the second drive motor 721 to run through the second control unit not only reduces the discharge of high-temperature steam in the cooking chamber 11, but also achieves heat dissipation for the body 10. At the same time, controlling the first drive motor 711 to stop running through the first control unit and controlling the second drive motor 721 to run through the second control unit also avoids the first drive motor 711 affecting the operation of the second drive motor 721, effectively ensuring the heat dissipation effect and performance stability of the steam air fryer.

[0030] like Figure 2 As shown, in an optional embodiment, the body 10 is provided with a first vent 13 communicating with the atmosphere and the heat dissipation cavity 12, and the cooling air assembly 60 is adapted to be disposed adjacent to the first vent 13. By disposing the cooling air assembly 60 adjacent to the first vent 13, external cold air can be better drawn into the heat dissipation cavity 12 to dissipate heat from the body 10; or, hot air inside the body 10 can be better exhausted, effectively improving the heat dissipation efficiency and effect of the body 10.

[0031] like Figure 2 As shown, in an optional embodiment, the body 10 is provided with an air outlet assembly 14, which has an air outlet channel 141. One end of the air outlet channel 141 is connected to the cooking cavity 11, and the other end is provided with a second vent 142 connected to the atmosphere. The second vent 142 is adapted to be located adjacent to the first vent 13. By providing the air outlet assembly 14 in the body 10, excess water vapor in the cooking cavity 11 can be discharged to avoid water vapor accumulation and condensation, which would affect the cooking effect of the food. At the same time, by placing the second vent 142 adjacent to the first vent 13, the cooling airflow discharged from the first vent 13 can also be used to cool the high-temperature water vapor and circulating heat flow discharged from the second vent 142, thereby reducing the risk of users being burned by the airflow discharged from the second vent 142 and effectively improving user safety.

[0032] like Figure 2 As shown, the second vent 142 is adapted to be located on the rear side of the body 10, and the first vent 13 is located above the second vent 142. By placing the second vent 142 on the rear side of the body 10 and placing the first vent 13 above the second vent 142, not only can the first vent 13 and the second vent 142 be hidden to improve the overall aesthetics of the steam air fryer, but the cooling airflow from the first vent 13 can also dissipate the circulating heat flow from the second vent 142, thereby reducing the chance of the rear side of the body 10 becoming too hot and causing burns to the user, and effectively improving the safety of using the air fryer.

[0033] like Figure 2 As shown, in an optional embodiment, the cooling air assembly 60 includes a cooling fan 61, which is adapted to have a spiral fan blade structure. By setting the cooling fan 61 to a spiral fan blade structure, not only can unidirectional air intake or exhaust be achieved, effectively improving air intake or exhaust efficiency and thus improving heat dissipation efficiency, but also the air intake or exhaust volume can be increased, thereby improving the heat dissipation effect of the body 10.

[0034] like Figure 2As shown, in an optional embodiment, the heat dissipation cavity 12 is adapted to surround at least a portion of the cooking cavity 11. By surrounding the cooking cavity 11 with the heat dissipation cavity 12, the cooling flow within the heat dissipation cavity 12 can be better utilized to dissipate heat from the cooking cavity 11. This not only reduces the outward transfer of high temperatures from the cooking cavity 11, thus preventing excessively high surface temperatures of the body 10 and potential burns to the user, but also reduces the outward transfer of high temperatures from the cooking cavity 11, thus preventing damage to electrical components such as the control system 80 and the drive system 70 outside the cooking cavity 11. This effectively ensures the performance stability and safety of the steam air fryer.

[0035] like Figure 2 As shown, in an optional embodiment, the steam generating system 40 includes a steam generating component 41 for converting water into steam, and the cooling air component 60 is adapted to be disposed adjacent to the steam generating component 41. By distributing the cooling air component 60 adjacent to the steam generating component 41, the cooling air component 60 can be better utilized to dissipate heat from the steam generating component 41 when the steam generating system 40 is running, i.e., during steam cooking. This not only avoids overheating of the steam generating component 41, which could lead to damage, but also effectively improves the performance stability and safety of the steam generating component 41. Furthermore, it reduces the outward transfer of high temperatures generated by the steam generating component 41, which could cause excessively high surface temperatures of the body 10 and damage to the internal electrical components of the body 10, thus effectively ensuring the performance stability of the steam air fryer.

[0036] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. The purpose of this utility model has been fully and effectively achieved. Those skilled in the art should understand that the embodiments of this utility model described above and shown in the accompanying drawings are merely examples and do not limit the scope of this utility model. For those skilled in the art, several simple deductions or substitutions can be made without departing from this utility model, and all such modifications or substitutions should be considered to fall within the scope of patent protection defined by the claims submitted herein.
