Description

Technical Field

[0001] The invention belongs to the technical field of electric ovens, and in particular relates to an automatic door opening oven. Background Art

[0002] A heat circulation oven (also often called a convection oven) is an oven that accelerates and evenly heats food by forcing hot air to flow. A heat circulation oven is usually equipped with a heating tube at the top or bottom of the oven's baking chamber as a heat source, and a fan is installed on the side of the baking chamber. The fan is driven to circulate the hot air inside the oven. Due to the continuous flow of hot air, the heating efficiency can be improved.

[0003] Among the existing barbecue recipes, there are meat and vegetable skewers or vegetable barbecue skewers. In this barbecue method, meat and vegetables are skewered with bamboo or iron skewers and grilled together, so that the fat and aroma of the meat are blended with the fresh taste of the vegetables.

[0004] When grilling meat and vegetable kebabs in a heat circulation oven, you may face the following problems:

[0005] The surface of meat is easily covered with oil, and the fat of the meat will melt and penetrate into the surface of the meat during the baking process, forming a layer of oil covering, which is conducive to locking moisture and forming a delicious grilled crust; however, for leafy vegetables, such as lettuce, spinach, broccoli, etc., it is difficult for their surfaces to be evenly covered with oil. During the baking process, the moisture on the surface of the vegetables is easy to lose. Because the fan accelerates the air flow, it will further accelerate the loss of moisture on the surface of the vegetables. The moisture on the surface of the vegetables evaporates quickly, causing the surface of the vegetables to dry out and the taste to deteriorate. Even when grilling meat and vegetable skewers, the meat is not yet cooked through, but the vegetables are already burnt.

[0006] Based on the above problems, the prior art (authorization announcement number: CN221903365U) discloses an oven, which is provided with a steam component inside the oven, and manually controls the amount of water vapor sprayed by providing a touch screen component; however, the technical solution does not explain when to start the steam component and the operating time of the steam component, which means that the user can only control the steam component based on experience. In fact, its manual records that "by providing a visual port and a visual window, it is convenient to observe the baking state of the food in the accommodating cavity", which also indirectly proves the above practice. Obviously, relying on manual control of the steam component, it is impossible to adjust the steam output in real time and accurately. Too much or too little steam may lead to unstable baking effect and affect the baking quality of food. The adjustment of the steam output requires a certain response time, and manual control also has a certain lag. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 6The present embodiment provides an automatic door opening oven, comprising an oven shell 1 with a hollow interior, an oven door 2, a heating structure 3 and a steam generating mechanism 4. The heating structure 3 is arranged in the oven shell 1 and is used to heat the interior of the oven shell 1. One end of the oven shell 1 is opened, and the oven door 2 is hinged to one side of the open end of the oven shell 1. The oven door 2 can lock or release its sealing matching relationship with the open end of the oven shell 1. The steam generating mechanism 4 is arranged at the top of the oven shell 1 and is used to increase the humidity inside the oven shell 1. By providing the steam generating mechanism 4, when the oven door 2 and the oven shell 1 are sealed and the heating structure 3 starts to work, the presence of food The moisture on the surface turns into water vapor due to the heating of the heating structure 3 and then leaves the surface of the food. At this time, the steam generating mechanism 4 starts to work, adding more high-temperature water vapor to the inside of the oven shell 1, thereby increasing the humidity in the oven shell 1, so that the water vapor in the oven shell 1 will adhere to the surface of the food again, ensuring that the moisture on the surface of the food is not lost while the food is heated. This solves the problem that the existing ovens all heat the food through the heating structure 3, but during the heating process, the moisture on the surface of the food will be evaporated due to the high temperature and then leave the surface of the food, making the surface of the food become hard after being heated by the oven, affecting the taste.

[0031] The steam generating mechanism 4 is equipped with a delivery pipeline 7, which extends to the air outlet path of the fan 5. An exhaust valve is connected between the steam generating mechanism 4 and the delivery pipeline 7. The heating mechanism 3 heats the gas in the baking chamber and serves as a heat source for the steam generating mechanism 4 to cooperate with the steam generating mechanism 4 to generate high-temperature water vapor. After reaching the threshold of the exhaust valve, the high-temperature water vapor leaks from the exhaust valve to maintain the internal humidity of the oven housing 1 within a predetermined range.

[0032] In some embodiments, the water storage bin 6 also reserves a water inlet to facilitate adding water to the water storage bin 6. The inner wall of the water inlet is provided with a plurality of markings arranged longitudinally and at intervals. Preferably, these markings can be projected onto the outside of the oven shell or made of transparent materials so that the operator can directly observe the markings or water levels. Different markings correspond to the amount of water to be added to different vegetables. During use, water is injected into the water inlet according to the type of vegetables so that the horizontal surface in the water storage bin 6 can reach the marked position of the corresponding vegetables; in this way, it is only necessary to heat the water storage bin 6 to automatically generate high-temperature water vapor required by the corresponding vegetables, thereby realizing humidity compensation inside the oven shell 1, and it is no longer necessary to manually control the amount of high-temperature water vapor generated. In addition, a detachable end cover can be installed at the water inlet. When it is not necessary to add water to the water storage bin 6, the water inlet can be sealed by the end cover;

[0033] The exhaust valve has a deflation critical point, and the deflation critical point of the exhaust valve is related to the heating time of the vegetable and the temperature in the baking chamber. Specifically, taking vegetable A as an example, assuming that after vegetable A has been heated for T in an environment of temperature K, it is measured that the surface of vegetable A is in a dry state, wherein, for vegetable A, temperature K is negatively correlated with heating time T, and the larger the value of temperature K is, the smaller the value of heating time T is, and the smaller the value of temperature K is, the larger the value of heating time T is. It can be understood that the higher the temperature in the baking chamber, the shorter the time it takes for the surface of vegetable A to reach a dry state, and vice versa. At this time, when the surface of vegetable A reaches a dry state, The state is the reference point, and each temperature (the temperature in the baking chamber) has a heating time corresponding to the temperature. Other reference points of the surfaces of other vegetables reaching a dry state can also be measured based on the above method. The critical point of the exhaust valve is determined based on the surface of vegetable A reaching a dry state, that is, when the surface of vegetable A reaches a dry state, the exhaust valve reaches the critical point of exhaust and releases high-temperature water vapor, or the critical point of the exhaust valve reaches the critical point of exhaust earlier than the surface of vegetable A reaches a dry state, that is, within 1-5 seconds before the surface of vegetable A reaches a dry state, the exhaust valve reaches the critical point of exhaust and releases high-temperature water vapor.

[0034] In order to ensure that the high-temperature water vapor released by the steam generating mechanism 4 toward the interior of the oven shell 1 can flow throughout the interior of the oven shell 1, ventilation slots are opened on the inner side wall of the oven shell 1, and the ventilation slots are interconnected with the interior of the oven shell 1. A fan 5 is arranged in the ventilation slots, and the fan 5 is used to blow air to the interior of the oven shell 1; by providing the fan 5, the high-temperature water vapor in the oven shell 1 can float everywhere in the oven shell 1, and the position of the fan 5 is usually fixed, mainly arranged on one side of the interior of the oven shell 1, and the hot air is circulated in the oven by driving the fan 5.

[0035] Specifically, the steam generating mechanism 4 of the present scheme includes an internally hollow water storage tank 6 and a delivery pipeline 7. The interior of the water storage tank 6 is filled with water. The water storage tank 6 is made of heat-conducting material, and the water inside the water storage tank 6 will not fill up the water storage tank 6, so that when the water storage tank 6 generates high-temperature water vapor after subsequent heating, the water storage tank 6 has reserved space for storing high-temperature water vapor. The water storage tank 6 is arranged at the top of the oven shell 1, and the delivery pipeline 7 is arranged at the top of the oven shell 1. The two ends of the delivery pipeline 7 are respectively connected to the water storage tank 6 and the ventilation slot. By providing the delivery pipeline 7, the high-temperature water vapor in the water storage tank 6 will move to the ventilation slot through the delivery pipeline 7, and will be blown to the interior of the oven shell 1 through the fan 5 provided in the ventilation slot. Specifically, the heating mechanism 3 cooperates with the fan 5 to form a hot air circulation inside the oven shell. Therefore, when the high-temperature water vapor is delivered to the air outlet path of the fan 5, the airflow blown by the fan 5 will drive the high-temperature water vapor into the interior of the oven shell 1, or in other words, the high-temperature water vapor is added to the hot air circulation inside the oven shell 1, thereby maintaining the internal humidity of the oven shell 1 within a certain range.

[0036] Furthermore, in order to ensure that the water in the steam generating mechanism 4 can only move to the ventilation slot through the delivery pipeline 7 after it forms high-temperature water vapor, the exhaust valve of the present scheme includes a sealing plate 8 and a sealing spring 9. A sealing slot is opened on the top of one end of the water storage tank 6, and the sealing plate 8 is arranged on the sealing slot. The two ends of the sealing spring 9 are respectively connected to the sealing plate 8 and the water storage tank 6. The sealing plate 8 can lock or release its sealing cooperation relationship with the sealing slot. The delivery pipeline 7 is respectively connected to the sealing slot and the ventilation slot; when the heating structure 3 starts to work, the water in the water storage tank 6 will gradually turn into high-temperature water vapor due to the temperature generated when the heating structure 3 is working, resulting in an increase in the air pressure in the water storage tank 6. The sealing plate 8 will be due to the water storage tank 6. When the air pressure rises, the sealing cooperation relationship between the sealing sheet 8 and the sealing slot is released by overcoming the force between the sealing sheet 8 and the sealing spring 9, so that the high-temperature water vapor in the water storage bin 6 will overflow through the sealing slot and move to the ventilation slot through the delivery pipeline 7. As the air pressure in the water storage bin 6 decreases, the sealing sheet 8 will be reset due to the force of the sealing spring 9, so that the sealing sheet 8 will maintain a sealing cooperation relationship with the sealing slot again. In this embodiment, a conventional exhaust valve can also be used to replace the above-mentioned sealing sheet 8 and sealing spring 9. At this time, since the fan 5 is still in operation, the high-temperature water vapor overflowing from the sealing sheet 8 will enter the ventilation slot, and the wind formed by the fan 5 will bring the high-temperature water vapor out of the ventilation slot;

[0037] In order to ensure the sealing fit between the sealing sheet 8 and the sealing slot, the exhaust valve of the present scheme also includes a limiting block 10, which is arranged in the water storage bin 6, and one end of the limiting block 10 is projected to the plane of the sealing slot to extend into the sealing slot. The limiting block 10 can lock or release its abutting fit with the sealing sheet 8. By providing the limiting block 10, after the sealing sheet 8 and the limiting block 10 are fitted together, the sealing sheet 8 can be restricted from continuing to move toward the inside of the water storage bin 6, thereby realizing the sealing fit between the sealing sheet 8 and the sealing slot.

[0038] It is worth noting that the problem of the taste of food affected by water loss on the food surface is not applicable to all foods. Therefore, when the food whose taste is not affected by water loss on the food surface is placed in the oven, the steam generating mechanism 4 does not need to work. Based on this, in order to better control the start and stop of the steam generating mechanism 4, the steam generating mechanism 4 of this scheme also includes a heat insulating layer 11, which is rotatably sleeved on the surface of the water storage bin 6, and the heat insulating layer 11 can lock or release its position between the water storage bin 6 and the baking cavity (or the heating structure 3); by providing the heat insulating layer 11, when the heat insulating layer 11 is rotated to between the water storage bin 6 and the heating structure 3, due to the existence of the heat insulating layer 11, the temperature generated when the baking cavity (or the heating structure 3) is working cannot be transmitted to the water storage bin 6, thereby making it impossible to increase the air pressure in the water storage bin 6, so that the water in the water storage bin 6 cannot move to the outside of the water storage bin 6 by releasing the sealing cooperation relationship between the sealing sheet 8 and the sealing slot hole, so that the exhaust valve cannot release high-temperature water vapor into the oven shell 1. Similarly, when the insulation layer 11 rotates to the top of the water storage bin 6, the insulation layer 11 is no longer located between the baking chamber (or the heating structure 3) and the water storage bin 6. The temperature of the heating structure 3 during operation will be transferred to the water storage bin 6, thereby increasing the air pressure in the water storage bin 6, and then enabling the exhaust valve to release high-temperature water vapor into the oven shell 1.

[0039] In addition, it should be noted that in order to ensure the normal operation of the insulation layer 11, the cross-section of the insulation layer 11 of the present embodiment is semicircular, the cross-section of the water storage tank 6 is annular, and the insulation layer 11 is sleeved on the surface of the water storage tank 6 and rotates along the central axis of the water storage tank 6.

[0040] Furthermore, in order to control the rotation of the thermal insulation layer 11, the steam generating mechanism 4 of the present embodiment also includes a rotating block 12. A rotating slot is opened inside the oven shell 1, and the rotating slot is communicated with the outside. The rotating block 12 is rotatably arranged in the rotating slot. The rotating block 12 is coaxially connected to the thermal insulation layer 11, and part of the side wall of the rotating block 12 protrudes from the outside of the oven shell 1. Through such an arrangement, a person can rotate by twisting the rotating block 12, thereby controlling the thermal insulation layer 11 to rotate.

[0041] In addition, it should be noted that in order to prevent the internal air pressure of the oven shell 1 from being too high, which may cause an explosion when the oven door 2 is opened, the steam generating mechanism 4 of the present scheme also includes a relief valve 13. The oven shell 1 is provided with an exhaust slot, which is respectively connected to the ventilation slot and the external environment, and the relief valve 13 is arranged in the exhaust slot. By providing the relief valve 13, when the air pressure in the oven shell 1 is too high, the excess air pressure will overflow to the outside of the oven shell 1 through the relief valve 13, so that the air pressure in the oven shell 1 is always maintained at a constant value.

[0042] The present solution is also provided with a rotating motor 14, which is arranged on the top of the oven housing 1 and connected to one end of the oven door 2. The rotating motor 14 is used to control the rotation of the oven door 2. By providing the rotating motor 14, the oven door 2 can be automatically opened and closed.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
