Description

Technical Field

[0001] This utility model relates to the field of ovens, and more specifically, to a scald-proof oven. Background Technology

[0002] In modern life, ovens are a common kitchen appliance widely used in homes and businesses. Whether it's home baking enthusiasts making bread, cakes and other pastries, or restaurants roasting meats, pizzas and other delicacies, ovens play an important role. As people's quality of life improves, the demand for ovens is not only reflected in their versatility of functions, but also in their safety. However, when using existing ovens, operators can easily touch the oven door and get burned when opening it to take out food.

[0003] Regarding the aforementioned issue of burns caused by touching the oven door when opening it to remove food, a thorough search revealed a scalding oven with patent publication number CN222828465U. This device, belonging to the oven field, uses a heat insulation plate positioned between the handle and the door body on the side of the door away from the opening. A certain gap exists between the heat insulation plate and the door body, and between the heat insulation plate and the handle. When opening the door by gripping the handle to remove food from the oven cavity, the heat insulation plate insulates against the heat absorbed by the door body, preventing burns from direct contact with the door.

[0004] However, the aforementioned anti-scalding oven still has some problems. For example, when in use, the heat insulation plate completely obscures the door, requiring a large volume and affecting the overall aesthetics. Furthermore, most ovens have a viewing panel for observing the interior, while the heat insulation plate makes it inconvenient for users to observe the oven's interior through the viewing panel on the door, thus reducing the device's effectiveness. To address these problems, this utility model proposes an anti-scalding oven. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a scalding oven.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scalding oven, comprising an oven body, a door, and a transparent panel, and also including a handle, which comprises two support plates and a pull rod fixedly installed between the two support plates. A scalding plate with an arc-shaped structure is rotatably provided between the two support plates via a rotating shaft. A torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively fixedly connected to the support plate and the scalding plate. There is a gap between the scalding plate and the door.

[0007] A protective frame is fixedly installed at the opening of the oven body. The protective frame is connected to the oven door, and a protruding rib that can abut against the oven door is fixedly installed on the protective frame.

[0008] A further preferred embodiment: the anti-scalding plate includes an integrally formed first arc-shaped plate and a second arc-shaped plate, the first arc-shaped plate being bent toward the door, and the second arc-shaped plate having the opposite orientation to the first arc-shaped plate.

[0009] A further preferred embodiment: an arc-shaped groove is formed at the second arc-shaped plate, and the arc-shaped groove formed by the second arc-shaped plate can fit against the back of the user's palm.

[0010] A further preferred embodiment: a heat insulation pad is fixedly installed on the arc-shaped plate relative to the box door.

[0011] A further preferred embodiment: an auxiliary plate is fixedly installed at the bottom of the protective frame.

[0012] A further preferred embodiment: both support plates are fixedly equipped with abutment rods that can abut against the side of the first arc-shaped plate opposite to the pull rod.

[0013] A further preferred embodiment: the oven body has multiple first heat dissipation holes through its sides and back, multiple second heat dissipation holes through its bottom, and a cooling fan is fixedly installed inside the oven body.

[0014] A further preferred embodiment: the oven body includes an inner liner and an outer shell, an aluminum foil reflective film is fixedly installed on the inner wall of the outer shell of the oven body, and multiple thermochromic warning strips are fixedly installed on the oven door.

[0015] Beneficial effects:

[0016] 1. By incorporating a heat shield, the rotatable heat shield effectively prevents heat from the oven door from being transferred to the user's hand when holding the handle, without affecting the use of the transparent panel, thus reducing the risk of burns. The curved structure of the heat shield conforms to ergonomics, making it more comfortable to hold and improving the user experience. At the same time, the torsion spring design ensures that the heat shield can automatically reset without affecting the normal operation of the oven.

[0017] 2. With the addition of an arc-shaped groove and a heat-insulating pad, the arc-shaped groove design greatly improves grip comfort, reduces hand fatigue, and is suitable for different hand sizes. During oven operation, even if the oven door is hot, users can easily grip the handle to operate it, effectively preventing burns and improving safety.

[0018] 3. By setting an abutment rod, the reset position of the anti-scalding plate is precisely controlled, ensuring that the anti-scalding plate is always in the best anti-scalding state during daily use of the oven, and avoiding the impact of excessive rotation of the anti-scalding plate on use or reduction of anti-scalding performance.

[0030] The following will refer to the appendix in the embodiments of this utility model. Figures 1-10 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0031] Please see Figure 1-10 In this embodiment of the utility model, an anti-scalding oven includes an oven body 1, a door 2, and a transparent panel 15, and also includes a handle 4, which includes two support plates 41 and a pull rod 42 fixedly installed between the two support plates 41. An anti-scalding plate 5 with an arc-shaped structure is rotatably provided between the two support plates 41 through a rotating shaft 12. A torsion spring 13 is sleeved on the rotating shaft 12, and the two ends of the torsion spring 13 are fixedly connected to the support plate 41 and the anti-scalding plate 5 respectively. There is a gap between the anti-scalding plate 5 and the door 2. A protective frame 11 is fixedly installed at the opening of the oven body 1 and is connected to the door 2. A protruding rib 9 that can abut against the door 2 is fixedly installed on the protective frame 11.

[0032] Specifically, when the user holds the handle 4 to open the door, the hand movement causes the anti-scalding plate 5 to rotate around the pivot 12. The torsion spring 13 generates torque, causing the anti-scalding plate 5 to always tend to rotate back towards the oven door 2. Under normal conditions, a certain gap is maintained between the anti-scalding plate 5 and the oven door 2 to avoid heat transfer from contact with the oven door 2. When holding the handle to open the door, the anti-scalding plate 5 will fit against the hand to provide anti-scalding protection. This design, through the rotatable anti-scalding plate 5, can effectively block the heat from the oven door 2 from being transferred to the hand when the user holds the handle 4 without affecting the use of the transparent panel 15, reducing the risk of burns. The arc-shaped structure of the anti-scalding plate 5 conforms to ergonomics, making it more comfortable to hold and improving the user experience. At the same time, the design of the torsion spring 13 ensures that the anti-scalding plate 5 can automatically return to its original position without affecting the normal operation of the oven.

[0033] It should be noted that in this embodiment, by using the rib 9 instead of the silicone strip, the protective frame 11 can block some of the heat leaking from the connection between the oven door 2 and the oven body 1 from spreading outward when the oven is working. Through the dual heat insulation effect of the protective frame 11 and the rib 9, the overall heat insulation effect is improved. The anti-scalding plate 5 is made of a high-temperature resistant and heat-insulating material, such as high-strength plastic with added special heat-insulating filler. In addition, a heat-insulating sleeve can be fitted on the handle 4. Furthermore, compared with the prior art, this device aims to solve the problem that in the prior art, when the oven is in use, the heat insulation plate completely blocks the door, which not only requires a large volume and affects the overall aesthetics, but also most ovens have a viewing plate 15 for observing the interior. The setting of the heat insulation plate makes it inconvenient for users to observe the interior of the oven through the viewing plate 15 on the door, which reduces the effectiveness of the device.

[0034] In this embodiment of the utility model, such as Figures 7 to 9As shown, the anti-scalding plate 5 includes an integrally formed first arc-shaped plate 51 and a second arc-shaped plate 52. The first arc-shaped plate 51 is bent towards the door 2, and the second arc-shaped plate 52 faces the opposite direction to the first arc-shaped plate 51. An arc-shaped groove 16 is formed in the second arc-shaped plate 52, which can fit against the back of the user's palm. Specifically, the first arc-shaped plate 51 is bent towards the door 2, and the second arc-shaped plate 52 faces the opposite direction to the first arc-shaped plate 51. The arc-shaped groove 16 formed by it can fit against the back of the user's palm, providing additional heat insulation protection for the back of the palm when holding it, and the fitting design enhances the stability of the grip. Secondly, when the user places their hand in the arc-shaped groove 16, depending on the size of the user's palm, the palm will compress the arc-shaped groove. The groove 16 allows the anti-scalding plate 5 to rotate towards the oven door 2, while the curved groove 16 continuously conforms to the back of the user's palm to protect the palm and improve the versatility of the device, making it suitable for palms of different sizes. The design of the curved groove 16 greatly improves the comfort of holding and reduces hand fatigue. During the operation of the oven, even if the oven door 2 is hot, the user can easily hold the handle 4 to operate it and effectively prevent burns, improving the safety of use. It should be noted that the connection between the first curved plate 51 and the second curved plate 52 can be smoothly transitioned to avoid sharp edges scratching the user. At the same time, the curvature of the second curved plate 52 can be optimized according to big data on human palm size to adapt to the palms of different people and improve versatility.

[0035] In this embodiment of the utility model, such as Figure 9 As shown, a heat insulation pad 14 is fixedly installed on the curved plate relative to the door 2. Specifically, the heat insulation pad 14 further enhances the heat insulation effect of the anti-scalding plate 5, working in synergy with the structural design of the anti-scalding plate 5 itself to provide users with more reliable anti-scalding protection. At the same time, the heat insulation pad 14 can also buffer the possible collision between the anti-scalding plate 5 and the door 2 to a certain extent, protecting the surfaces of the door 2 and the anti-scalding plate 5 from damage. The heat insulation pad 14 should be made of a material that is resistant to high temperatures, aging, and has a certain degree of flexibility, such as a ceramic fiber heat insulation pad 14.

[0036] In this embodiment of the utility model, such as Figure 4 As shown, an auxiliary plate 10 is fixedly installed at the bottom of the protective frame 11. Specifically, the design of the protective frame 11 and the auxiliary plate 10 effectively reduces the heat radiation from the environment around the oven, lowering the risk of burns to the user during oven operation. At the same time, the protective frame 11 enhances the structural strength of the oven opening, extending the oven's service life. The protective frame 11 and the auxiliary plate 10 can be made of metal and have surface heat insulation treatment, such as spraying a heat insulation coating.

[0037] In this embodiment of the utility model, such as Figure 10As shown, both support plates 41 are fixedly equipped with abutment rods 17 that abut against the side of the first arc-shaped plate 51 opposite to the pull rod 42. Specifically, when the anti-scalding plate 5 rotates back to its initial position under the action of the torsion spring 13, the abutment rods 17 limit the rotation angle of the anti-scalding plate 5, ensuring that a suitable gap is maintained between the anti-scalding plate 5 and the oven door 2, thus maintaining a good anti-scalding effect. The setting of the abutment rods 17 precisely controls the reset position of the anti-scalding plate 5, ensuring that the anti-scalding plate 5 is always in the best anti-scalding state during daily use of the oven, avoiding the impact of excessive rotation of the anti-scalding plate 5 on use or a reduction in anti-scalding performance. It should be noted that the length and position of the abutment rods 17 can be finely adjusted according to actual testing to achieve the best reset control effect of the anti-scalding plate 5. A buffer pad can be installed at the contact part between the abutment rods 17 and the anti-scalding plate 5 to reduce collision wear and noise.

[0038] In this embodiment of the utility model, such as Figures 1 to 6 As shown, the oven body 1 has multiple first heat dissipation holes 6 penetrating through its sides and back, and multiple second heat dissipation holes 8 penetrating through its bottom. A cooling fan 3 is fixedly installed inside the oven body 1. Specifically, the oven body 1 has multiple first heat dissipation holes 6 penetrating through its sides and back, and multiple second heat dissipation holes 8 penetrating through its bottom. The heat generated inside the oven during operation is dissipated outward through these heat dissipation holes. At the same time, the cooling fan 3 fixedly installed inside the oven body 1 is activated when the oven is in operation, accelerating the airflow inside the oven, exhausting hot air through the heat dissipation holes, and introducing external cold air to form a circulating heat dissipation. The efficient heat dissipation design can quickly reduce the internal temperature of the oven, reduce the accumulation of heat in the oven body 1, prevent the oven shell from overheating, and effectively reduce the risk of users being burned when operating the oven. At the same time, good heat dissipation helps to maintain a uniform internal temperature of the oven, improve the baking effect, and extend the service life of the oven.

[0039] In this embodiment of the utility model, such as Figures 1 to 7As shown, the oven body 1 includes an inner liner and an outer shell. An aluminum foil reflective film is fixedly installed on the inner wall of the outer shell of the oven body 1. Multiple thermochromic warning strips 7 are fixedly installed on the oven door 2. Specifically, the aluminum foil reflective film (not shown in the figure) effectively reduces the temperature of the oven shell, enhances the oven's heat insulation performance, improves energy efficiency, and reduces heat waste. At the same time, reducing the shell temperature prevents surrounding items from being damaged by heat, improving safety. The thermochromic warning strips 7 can be made of thermochromic ceramic glaze. The core component of thermochromic ceramic glaze is the addition of rare earth elements to the ceramic glaze. (e.g., oxides of erbium and dysprosium) or transition metal compounds (e.g., bismuth vanadate) are fixed on a ceramic substrate by high-temperature sintering (800-1200℃). The color-changing principle is that the electronic energy levels of rare earth ions change with temperature, resulting in changes in the reflection / absorption characteristics of visible light (e.g., white at low temperatures, turning pink above 60℃). By making ceramic patches from thermochromic ceramic glaze, these patches are pasted onto the oven control panel or outer shell (i.e., forming thermochromic warning strip 7). They have excellent high-temperature resistance (long-term resistance to temperatures above 200℃, far exceeding the maximum temperature of the outer shell), and are scratch-resistant and easy to clean.

[0040] Working principle: When the oven is working, the high temperature generated in the inner cavity is reflected back into the interior through the aluminum foil reflective film, reducing the radiant heat to the outer shell. The ribs 9 on the protective frame 11 are in close contact with the oven door 2, blocking heat leakage from the door gap. The auxiliary plate 10 further blocks the heat diffusion from the bottom and guides the heat flow upward. When the user holds the handle 4, the palm naturally fits the arc groove 16 of the second arc plate 52. The anti-scalding plate 5 automatically adjusts its angle under the action of the torsion spring 13. The first arc plate 51 maintains a safe distance from the oven door 2 through the heat insulation pad 14. The contact rod 17 ensures the precise position of the anti-scalding plate 5 when it resets, maintaining the optimal heat insulation gap. At the same time, a temperature sensor (not shown in the figure) connected to the control device of the oven body 1 is installed between the inner cavity and the outer shell of the oven body 1. The cooling fan 3 is connected to the control device. When the oven body 1 is in the inner cavity, the temperature sensor is connected to the control device. When the temperature between the inner cavity and the outer shell reaches the warning value, the control device activates the cooling fan 3, which expels the internal hot air through multiple first heat dissipation holes 6 on the oven body 1. After the hot air is exhausted, external cold air is replenished from the second heat dissipation hole 8 at the bottom, forming continuous convection cooling. The thermochromic coating displays the temperature status of the oven door 2 in real time, and changes color to warn when the temperature exceeds the safety threshold. The overall structure has a multi-layer anti-scalding effect. When the user holds the handle 4, it can effectively block the heat from the oven door 2 from being transferred to the hand, preventing the user's palm from directly contacting the oven door 2 and reducing the risk of burns. The arc-shaped structure of the anti-scalding plate 5 conforms to ergonomics, making it more comfortable to hold and improving the user experience. At the same time, the design of the torsion spring 13 ensures that the anti-scalding plate 5 can automatically reset without affecting the normal operation of the oven and without obstructing the transparent panel 15 of the oven door 2, ensuring the effectiveness of use.
