Description

Technical Field

[0001] The utility model relates to the technical field of steaming cabinets, in particular to a heating structure used for steaming cabinets. Background Art

[0002] With the development of economy and the improvement of material living standards, various diseases of affluence have come along, and people are paying more and more attention to food quality and health. Among various cooking methods, "steaming" is the only one that can keep the original flavor of food and is healthy. The shorter the "steaming" time, the better the taste and original flavor of the food will be. However, various equipment on the market currently have the following disadvantages:

[0003] Too much steam: This causes more steam to condense on the food during the steaming process. After cooking, the food will be soaked in more juice, affecting the taste of the food. In addition, some nutrients in the food will penetrate into the juice due to density differences, affecting the nutritional content of the food.

[0004] Because steaming and cooking equipment are open or low-pressure products, the steam temperature from the steam generator is relatively low. After cooling through the pipes and cavity, the actual food cooking cavity temperature is low and cannot meet the needs of fast cooking.

[0005] Therefore, we propose a heating structure for a steaming cabinet to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a heating structure for a steam cabinet to solve the problems raised by the above background technology.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. By setting up the vortex heater and the steam generator, the steam is reheated by the vortex heater, which can greatly reduce the pressure in the cooking chamber, effectively reduce product costs, and improve safety. The higher temperature steam can also cook food in a shorter time and maintain its taste and nutrition.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1-4 A heating structure for a steam cabinet comprises a shell 1, a steam generator 5 is fixedly installed near one side of the bottom of the inner cavity of the shell 1, a water inlet pipe is plugged into one side of the steam generator 5 near the bottom, the number of the steam generator 5 and the vortex heater 2 can be 2n, and the connection structure can be connected in series or in parallel. Corresponding to different cooking needs, a conduit is installed near one side of the top of the steam generator 5, and the vortex heater 2 is installed at the bottom of the conduit, a cooking cavity 3 is arranged near the middle position of the inner cavity of the shell 1, a steaming rack 4 is installed near the bottom of the inner cavity of the cooking cavity 3, and a guide tube is plugged into the bottom of the vortex heater 2, and the guide tube is plugged into the cooking cavity 3, and the inner cavity of the steam generator 5 An alarm component 6 is provided. When the steam generator 5 is working, the steam is secondary heated by the vortex heater 2, and the temperature of the steam is increased again, so that the cooking temperature of the food cooking cavity 3 can reach above 130°C under a relatively low pressure of 1.1MPa, while the inner cavity pressure of the traditional steam cabinet needs to reach 1.2MPa to reach this cooking temperature; the humidity of the steam after secondary heating is lower than the relative humidity of the steam directly discharged, and the rapid condensation during cooking is effectively controlled, which can greatly reduce the pressure of the cooking cavity, effectively reduce the product cost, and improve safety; the higher temperature steam can also cook food in a shorter time to maintain its taste and nutrition.

[0026] The guide pipe is located at the bottom of the steaming rack 4, which can improve the effect of steaming food with the steam of the device.

[0027] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 , Figure 3 and Figure 4The alarm assembly 6 includes a connecting plate 61 fixedly installed on both sides of the inner cavity of the steam generator 5 and a first pressure sensor 62 fixedly installed on the top of the connecting plate 61 near the middle position. A floating plate 63 is commonly arranged on the top of the connecting plate 61. A second pressure sensor 64 is fixedly installed on the top of the floating plate 63 near the rear side. A stopper 65 is fixedly installed on the top of the inner cavity of the steam generator 5. Two alarms 66 are fixedly installed on the top of the outer shell 1 near the rear side. When water is added through water inlet, the floating plate 63 can move upward. When the water level reaches a certain position, the second pressure sensor 64 can be squeezed with the cooperation of the stopper 65, so that the adjacent alarm 66 can be operated, prompting the staff that the inner cavity of the steam generator 5 is full of water. When the water level drops, the first pressure sensor 62 and the adjacent second pressure sensor 64 can be used to prompt the staff that the water level is too low and needs water injection, thereby improving the use effect of the device.

By setting the vertical rods 631, the floating plate 63 can slide stably.

[0029] The second pressure sensor 64 is electrically connected to the adjacent alarm 66 , and the first pressure sensor 62 is electrically connected to the adjacent alarm 66 .

[0030] Working principle: When the steam generator 5 is working, the steam is reheated by the vortex heater 2, and the temperature of the steam is increased again, so that the cooking temperature of the food cooking chamber 3 can reach above 130°C under a relatively low pressure of 1.1MPa, while the traditional steam cabinet needs to reach an internal pressure of 1.2MPa to reach this cooking temperature; the humidity of the steam after reheating is lower than that of the steam directly discharged, and the rapid condensation during cooking is effectively controlled, which can greatly reduce the pressure of the cooking chamber, effectively reduce the product cost, and improve safety; the higher temperature steam It is also possible to cook food in a shorter time while maintaining its taste and nutrition. When water is injected into the inner cavity of the steam generator 5 through the water inlet pipe, the float plate 63 can move upward under the buoyancy of the water. When the water level reaches a certain position, the second pressure sensor 64 can be squeezed with the cooperation of the block 65, so that the adjacent alarm 66 can be operated to remind the staff that the inner cavity of the steam generator 5 is full of water. When the water level drops, the first pressure sensor 62 and the adjacent second pressure sensor 64 can be used to remind the staff that the water level is too low and needs to be injected with water, thereby improving the use effect of the device.
