Abstract
Description
Technical Field
[0001] The utility model relates to a steam cooking utensil. Background Art
[0002] Current steam cooking appliances heat water into steam using a boiler or steam generator and deliver it directly to the cooking container. Because cooking containers are typically large, the steam's temperature initially ranges from 100°C to 130°C. It then rapidly cools down to below 100°C within the container. As the amount of steam entering the container increases, the temperature inside the container rises to around 130°C. This results in a long cooking time and significant nutrient loss from the food within the container. Utility Model Content
[0003] The purpose of the utility model is to provide a steam cooking appliance which can increase the steam temperature.
[0004] The purpose of this utility model is achieved in this way.
[0005] A steam cooking appliance includes a main unit and a water tank. A pipe is provided in the main unit to connect the water tank and a cooking container on the main unit. A water pump and a first heating device are provided on the pipe. The water pump sends water in the water tank into the first heating device. The first heating device heats the water into steam and sends it into the cooking container. A second heating device is provided on the pipe to heat the steam sent by the first heating device.
[0006] The utility model uses the second heating device to secondary heat the steam generated by the first heating device, so that the steam reaches above 300 degrees Celsius and then enters the cooking container, thereby forming a flash steaming effect of quickly heating food in the cooking container.
[0007] Furthermore, the pipeline includes a water pipeline, a first steam pipeline, a heating steam pipeline and a second steam pipeline. The inlet end of the water pipeline is connected to the water tank, and the outlet end of the water pipeline is connected to the inlet of the first heating device. The water pump is arranged on the water pipeline. The inlet end of the first steam pipeline is connected to the steam outlet end of the first heating device, and the outlet end of the first steam pipeline is connected to the steam inlet end of the heating steam pipeline. The heating steam pipeline is coiled on the second heating device. The second heating device heats the heating steam pipeline. The steam outlet end of the heating steam pipeline is connected to the inlet end of the second steam pipeline, and the outlet end of the second steam pipeline is connected to the cooking container.
[0008] The pipeline design is reasonable, which facilitates the secondary heating device to heat the steam again.
[0009] Furthermore, the heating steam pipeline is a metal pipeline, and the steam inlet end and the steam outlet end of the heating steam pipeline both extend in a direction away from the second heating device.
[0010] The warming steam pipeline facilitates heating by the second heating device and prevents the second heating device from heating the steam inlet end and the steam outlet end of the warming steam pipeline.
[0011] Furthermore, the second steam pipeline and the warming steam pipeline are connected as one.
[0012] High-temperature steam is not easily leaked between the warming steam pipeline and the second steam pipeline, and the heat of the warming steam pipeline can also be transferred to the second steam pipeline to maintain the steam temperature in the second steam pipeline.
[0013] Furthermore, the first steam pipeline and the warming steam pipeline are connected into one.
[0014] Steam is not easily leaked between the warming steam pipeline and the first steam pipeline, and the heat of the warming steam pipeline can also be transferred to the first steam pipeline, thereby fully heating the steam for the second time.
[0015] Furthermore, the cooking container and the main unit are separately provided, and the outlet end of the second steam pipeline extends to the top of the main unit.
[0016] The cooking container is easy to clean.
[0017] Furthermore, the first heating device is a steam generator or a steam boiler.
[0018] Furthermore, the second heating device is a heating pipe, so that the heating steam pipeline is coiled outside the second heating device.
[0019] The utility model uses a second heating device to reheat the steam generated by the first heating device, so that the steam reaches above 300 degrees Celsius before entering the cooking container, thereby achieving a flash steaming effect in the cooking container to quickly heat the food. The reasonable pipeline design facilitates the second heating device to reheat the steam. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 3 This is a schematic diagram of the installation structure of the pipeline, water pump, first heating device and second heating device in Example 1. DETAILED DESCRIPTION
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Example 1, see Figure 1-3As shown, a steam cooking appliance includes a main unit 1, a water tank 2, and a cooking container (not shown). The water tank 2 is arranged on the side of the main unit 1 for easy water filling and cleaning. Preferably, the cooking container and the main unit 1 are arranged separately.
[0025] The main unit 1 is provided with a pipe 3 connecting the water tank 2 and the cooking container on the main unit 1. A water pump 4 and a first heating device 5 are provided on the pipe 3. The water pump 4 delivers water from the water tank 2 to the first heating device 5, which heats the water into steam for delivery to the cooking container. A second heating device 6 is provided on the pipe 3 to heat the steam delivered by the first heating device 5. Preferably, the first heating device 5 is a steam generator, but a steam boiler is also acceptable. The first heating device 5 is a heating tube, either a quartz heating tube or a halogen heating tube.
[0026] Specifically, the pipeline 3 includes a water pipeline 31, a first steam pipeline 32, a warming steam pipeline 33, and a second steam pipeline 34. The inlet of the water pipeline 31 is connected to the water tank 2, and the outlet of the water pipeline 31 is connected to the inlet of the first heating device 5. The water pump 4 is mounted on the water pipeline 31. The inlet of the first steam pipeline 32 is connected to the steam outlet of the first heating device 5, and the outlet of the first steam pipeline 32 is connected to the steam inlet of the warming steam pipeline 33. The warming steam pipeline 33 is coiled around the second heating device 6, which heats the warming steam pipeline 33. The steam outlet of the warming steam pipeline 33 is connected to the inlet of the second steam pipeline 34, which extends to the top of the main unit 1 to connect to the cooking container. Preferably, the warming steam pipeline 33 is a metal pipeline, and both the steam inlet and steam outlet of the warming steam pipeline 33 extend away from the second heating device 6. Preferably, the second steam pipeline 34 and the warming steam pipeline 33 are integrally connected. The first steam pipeline 32 and the warming steam pipeline 33 are connected as one.
[0027] The steam cooking appliance operates as follows: a cooking container is placed on the main unit 1, and food to be heated is placed inside the cooking container. The outlet end of the second steam line 34 is connected to the inner cavity of the cooking container, which is typically sealed. Water is filled into the water tank 2, and a water pump 4 pumps the water into the first heating device 5. The first heating device 5 heats the water into steam, typically at a temperature between 100°C and 150°C. The steam enters the warming steam line 33 through the first steam line 32. The second heating device 6 heats the steam in the warming steam line 33, raising its temperature to over 300°C. The high-temperature steam enters the inner cavity of the cooking container through the second steam line 34. The temperature of the cooking container inner cavity is at room temperature, and the volume of the cooking container inner cavity is typically not less than that of the warming steam line 33. The high-temperature steam flashes through the cooking container to quickly heat the food, thereby improving cooking efficiency and shortening cooking time.
