Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and in particular to a multi-functional microwave oven head and a multi-functional microwave oven. Background Technology

[0002] An air fryer is a cooking device that uses a light wave heat source to heat flowing air and then transfer the heat to the surface of food, thereby cooking it. A common structure includes an upper-mounted burner head with a pot body below it. Inside the burner head, a drive motor and a light wave heat source are arranged sequentially. A reflector is placed between the drive motor and the heat source. The drive shaft of the drive motor passes through the reflector and rotates on both sides of the reflector, connecting to fan blades. The fan blades on the side of the reflector corresponding to the heat source act as a hot air circulation fan to circulate hot air within the pot body. The fan blades on the side of the reflector opposite the heat source act as a cooling fan to dissipate heat and cool the interior of the burner head.

[0003] To enrich cooking modes and enhance the functionality of air fryers, products combining both air frying and grilling functions have emerged on the market. More precisely, these products feature both a closed pot and an open grill pan. Food is placed in the closed pot when air frying is needed, and in the open grill pan when grilling is required. However, because the two sets of fan blades on the original air fryer head are driven by the same motor shaft, they can only start or stop simultaneously. This makes the original air fryer head incompatible with multi-functional products. The existing hot air circulation fan cannot circulate hot air over the open food container. When using the open grill pan, turning on the hot air circulation fan causes air to flow outwards, leading to a rapid drop in food temperature and affecting grilling results. Conversely, stopping the hot air circulation fan means the cooling fan must also stop, impacting the heat dissipation of the burner. Therefore, for these multi-functional products with both open grilling and closed air frying functions, the burner head needs to be redesigned to better leverage the advantages of this multi-functional product. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a multi-functional microwave oven head that can be well applied to multi-functional products with open grilling and closed air fryer functions.

[0005] To achieve the above objectives, the technical solution of the present invention includes: a multi-functional microwave oven head, comprising a shell, a microwave heat source, a reflector, and a cooling fan, wherein the microwave heat source is annular and placed inside the reflector, characterized in that the reflector includes a reflective part and a ventilation part with adjustable vents; the cooling fan is located above the ventilation part, and when the multi-functional microwave oven head is in an open grilling state, the ventilation part is adjusted to a closed state, and the cooling fan cannot blow air onto the heating area through the ventilation part; when the multi-functional microwave oven head is in a closed air fryer state, the ventilation part is adjusted to an open state, and the cooling fan blows air onto the heating area through the ventilation part.

[0006] This invention provides a multifunctional lightwave oven head. The reflector is divided into a reflective part and a ventilation part. A cooling fan is installed above the ventilation part of the reflector inside the oven head. Since the vent of the ventilation part is adjustable, it can be flexibly controlled to be open or closed. In the open grilling mode, by adjusting the vent to the closed state, the ventilation part cannot vent out, and the air from the cooling fan blows out from the back of the reflector to cool the oven head, but cannot blow from the vent of the ventilation part to the heating area, thus affecting the heating of the heating area. In the closed air fryer mode, by adjusting the vent to the open state, the ventilation part can vent out. In addition to cooling the oven head by blowing air from the back of the reflector, the air from the cooling fan can also blow from the ventilation part to the heating area to achieve heat circulation heating.

[0007] Preferably, the ventilation section is a rotatable double-layered cover structure, comprising a fixed first cover and a rotatable second cover. The first and second covers are respectively provided with a first through hole and a second through hole. By rotating the second cover, the first and second through holes can be aligned or offset. When the first and second through holes are aligned, they are connected, and the ventilation opening is open. When the first and second through holes are offset, the body of the first cover blocks the second through hole, and the body of the second cover blocks the first through hole, and the ventilation opening is closed. This further optimizes the structure of the ventilation section. By setting the ventilation section as a rotatable double-layered cover structure with through holes on both layers, the alignment or offset of the through holes on the double-layered cover can be achieved through relative rotation of the covers, i.e., the opening or closing of the ventilation opening can be adjusted and controlled, enabling the burner to be used under different functions, making operation flexible and convenient.

[0008] Preferably, the first through hole and the second through hole are through holes of the same shape and size, and the first through hole and the second through hole are evenly distributed circumferentially on the first cover and the second cover, respectively, and the distance between two adjacent through holes is greater than the width of the through hole on the same circumference. This is a further optimization of the above solution. By optimizing the shape, size, arrangement, and distance between two adjacent through holes of the first and second through holes, the fit between the double-layer cover is more optimized and reasonable, avoiding incomplete closure of the vents and affecting the performance.

[0009] Preferably, the second cover is provided with a lever to facilitate its rotation, and the first cover is provided with an arc-shaped groove along the circumferential direction. The lever passes through the arc-shaped groove and rotates within it. This is a further optimization of the above solution. The combination of the lever and the arc-shaped groove facilitates the rotation of the cover and the adjustment of the ventilation opening. At the same time, the lever helps to limit the relative position of the second cover and the first cover, preventing the second cover from shifting away from the first cover.

[0010] Preferably, the distance the lever rotates within the arc-shaped groove is the distance between two adjacent through holes. This is a further optimization of the above solution. By limiting the rotation distance of the lever to between two adjacent through holes, it makes it faster to adjust the position relationship of the through holes when rotating the cover, which is beneficial for faster and more precise adjustment of the ventilation opening.

[0011] Preferably, the second cover is an annular cover, and the lever is disposed on the inner ring of the annular cover.

[0012] Preferably, the outer periphery of the first cover is fixedly connected to the reflective part by screws, and the inner periphery of the reflective part is provided with an inclined surface that abuts against the first cover. The inclined surface ensures the airtightness between the first cover and the reflective part, preventing the air from the cooling fan from blowing out from the gap between the first cover and the reflective part, thus affecting the airflow control effect of the ventilation part.

[0013] Preferably, the first cover and the reflective part are integrally formed, and the second cover is rotatably mounted on the first cover. This is an alternative to the above solution.

[0014] Another objective of this invention is to provide a multifunctional microwave oven that simultaneously possesses good heat circulation and heat dissipation effects in the closed air fryer function, and good grilling and heat dissipation effects in the open grilling function.

[0015] To achieve the above objectives, the technical solution of the present invention includes: a multi-functional microwave oven, comprising the aforementioned multi-functional microwave oven head, a base, an open grill pan, and a closed pot body; the open grill pan and the closed pot body are interchangeably mounted on the base. When the multi-functional microwave oven head is operating in the open grill function, the open grill pan is mounted on the base, and the ventilation section is adjusted to a closed vent state. By using the aforementioned multi-functional microwave oven head, when the microwave oven head is operating in the open grill function, the open grill pan is placed on the base, and by adjusting the ventilation section to a closed state, the airflow from the cooling fan can only pass through the back of the reflector to achieve a cooling effect, while the airflow from the cooling fan cannot blow from the ventilation section towards the heating area, thus avoiding affecting the grilling effect.

[0016] Preferably, when the multi-functional microwave oven head operates in the closed air fryer function, a closed pot body is mounted on the base, and the ventilation section is adjusted so that the vent is open. When using the closed air fryer function, the closed pot body is placed on the base. By adjusting the ventilation vent to the open state, the air from the cooling fan can not only be blown out from the back of the reflector for heat dissipation, but also blown from the ventilation section towards the heating area, circulating heat within the closed pot body and enabling the air fryer function to achieve heat circulation heating.

[0029] The present invention provides a multifunctional microwave oven head and a multifunctional microwave oven, with reference to the accompanying drawings.

[0030] An embodiment of the present invention for a multifunctional lightwave oven head:

[0031] Combination Figure 1 and Figure 2 The microwave oven head shown includes a housing 101, a microwave heat source 102, a reflector 103, a cooling fan 104, and a heat insulation cover 116. The microwave heat source 102 is annular. The reflector 103 includes a reflective part 105 and a ventilation part 106. The ventilation part 106 is provided with an adjustable vent 107. The cooling fan 104 is located above the ventilation part 106 of the reflector 103. The microwave heat source 102 is annularly arranged inside the reflective part 105. A heat insulation cover 116 is provided between the reflector 103 and the housing 101. Figure 3As shown, the ventilation section 106 has a double-layer cover structure, including a relatively fixed first cover 109 and a relatively rotatable second cover 110. In this embodiment, the outer periphery of the first cover 109 is fixedly connected by screws and a reflective part 105. The second cover 110 is disposed on the first cover 109 to form a double-layer cover structure. Since the first cover 109 is fixedly connected, the second cover 110 is placed directly on the first cover. The second cover 110 can rotate flexibly relative to the first cover 109. In other embodiments, the first cover 109 and the reflective part 105 can be an integrally formed structure. The second cover 110 is disposed on the first cover 109 to form a double-layer cover structure, which also allows the second cover 110 to rotate relative to the first cover 109. To enable the ventilation section 106 to achieve the effect of adjustable ventilation opening 107, a first through hole 111 is provided on the first cover 109, and a second through hole 112 is provided on the second cover. The adjustable ventilation opening 107 includes the first through hole 111 and the second through hole 112, such as... Figure 4 and Figure 5 As shown, the second cover 110 is rotated until the second through hole 112 completely overlaps with the first through hole 111, that is, the first through hole 111 and the second through hole 112 are connected to form an open vent 107. The vent 107 connects the cooling fan above the reflector and the heating area below the reflector, so that the air from the cooling fan is blown into the heating area through the vent 107; Figure 6 and Figure 7 As shown, when the second cover 110 is rotated to the point where the second through hole 112 is completely misaligned with the first through hole 111, that is, the second through hole 112 corresponds to the body of the first cover 109, and the first through hole 111 corresponds to the body of the second cover 110. The through holes on the double-layer cover are blocked by the corresponding bodies, which means that the ventilation part 106 is an airtight cover and the ventilation port 107 is in a closed state. At this time, the cooling fan above the reflector and the heating area below the reflector are separated, and the air from the cooling fan can only blow over the reflector and cannot blow air to the heating area below the reflector.

[0032] Combination Figures 3 to 7In the illustrated embodiment, the first through hole 111 and the second through hole 112 are through holes of the same shape and size. The first through hole 111 and the second through hole 112 are evenly distributed circumferentially on the first cover 109 and the second cover 110, respectively. To further optimize and ensure that the cover can completely block the through holes and the control effect of the ventilation opening, in this embodiment, the distance between two adjacent through holes is greater than the width of the through holes on the same circumference. Therefore, by rotating the second cover 110, the first through hole 111 and the second through hole 112 completely overlap, that is, the first through hole 111 and the second through hole 112 are connected to form an open ventilation opening 107; alternatively, the first through hole 111 and the second through hole 112 can be offset from each other, that is, the first through hole 111 is blocked by the body of the second cover 110, and the second through hole 112 is blocked by the body of the first cover 109, meaning that the ventilation opening 107 is adjusted to a closed state. Figure 4 and Figure 5 As shown, the vent 107 on the reflector 103 is in the open state. The first through hole 111 and the second through hole 112 are completely overlapped and connected to form the open vent 107. The air blown down from the cooling fan 104 onto the reflector 103 is blown downwards through the vent 107. Figure 6 and Figure 7 The diagram shows the vent 107 on the reflector 103 in the closed state. The first through hole 111 is blocked by the body of the second cover 110, and the second through hole 112 is blocked by the body of the first cover 109. Therefore, the vent 107 is closed, and the ventilation section 106 cannot allow the air from the cooling fan 104 to blow downwards from the ventilation section 106. In other embodiments, the shape and size of the first through hole 111 and the second through hole 112 can be different, and it is not limited that the first through hole 111 and the second through hole 112 need to be evenly distributed circumferentially. As long as the bodies of the first cover and the second cover can mutually cover the second through hole and the first through hole, the effect of this technical solution can be achieved.

[0033] Combination Figure 3 , Figure 5 and Figure 7 In the illustrated embodiment, the first cover 109 has an arc-shaped groove 114 along the circumferential direction, and the second cover 110 has a lever 113 at a corresponding position. The lever 113 passes through the arc-shaped groove 114 and can rotate within it. The rotation of the lever 113 drives the second cover 110 to rotate, thereby achieving the overlap or offset of the first through hole 111 and the second through hole 112. To facilitate control of the positioning of the first through hole 111 and the second through hole 112, in this embodiment, the rotatable distance of the lever 113 is set to the distance between two adjacent through holes. When the lever 113 rotates between the two endpoints of the arc-shaped groove 114, the overlap or offset state of the first through hole 111 and the second through hole 112 can be quickly obtained.

[0034] Combination Figure 3 , Figure 4 and Figure 6 In the embodiment shown, in order to reduce the weight of the double-layer cover and make the second cover easier to rotate, the second cover 110 is configured as an annular cover, wherein the lever 113 is set on the inner ring, and the first cover 109 is provided with an arc-shaped groove 114 at the position corresponding to the lever 113. The lever 113 passes through the arc-shaped groove 114 and rotates within the arc-shaped groove 114.

[0035] like Figure 8 In the embodiment shown, the first cover 109 and the reflective part 105 are fixedly connected by screws. There may be a gap between the first cover 109 and the reflective part 105 that allows air to pass through. In order to avoid the gap between the first cover 109 and the reflective part 105 affecting the ventilation control effect of the ventilation part 106, an inclined surface 115 is provided on the inner circumference of the reflective part 105. The inclined surface 115 abuts against the first cover 109. The structure between the ventilation part 106 and the reflective part 105 is further optimized by the action of the inclined surface 115.

[0036] An embodiment of the present invention for a multifunctional lightwave oven:

[0037] Combination Figure 9 and Figure 10 As shown, including Figures 1 to 8 The multi-functional microwave oven head 100, base 200, open baking tray 300, and closed pot body 400 are shown.

[0038] When the multi-functional microwave oven head is working in the open grill function, combined with Figure 6 , Figure 7 and Figure 9 As shown, an open baking tray 300 is set on the base 200. At the same time, the ventilation port 107 of the ventilation section 106 is adjusted to the closed state, that is, the first cover 109 and the second cover 110 are rotated relative to each other until the first through hole 111 and the second through hole 112 are blocked by the body of the second cover 109 and the body of the first cover 110, respectively. This adjusts the burner to the open grilling mode. The air of the cooling fan 104 blows directly from between the reflector 103 and the heat insulation cover 116 to cool down the burner, but cannot blow air onto the grilling area below the burner to avoid affecting the grilling effect.

[0039] When the multi-functional microwave oven head is operating in the closed air fryer function, combined with Figure 3 and Figure 8As shown, a closed pot body 400 is provided on the base 200. The first cover 109 and the second cover 110 are rotated relative to each other until the first through hole 111 and the second through hole 112 are aligned, that is, the vent 107 of the ventilation section 106 is adjusted to the open state, thereby adjusting the burner to the closed air fryer heating mode. The air from the cooling fan 104 blows out from between the reflector 103 and the heat insulation cover 116 to cool down the burner, and blows from the vent 107 of the ventilation section 106 to the closed pot body 400 below the burner, thereby realizing heat circulation heating inside the pot body.

[0040] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
