Description

Technical Field

[0001] This utility model relates to the field of constant pressure steam oven technology, and in particular to a multi-head adjustable constant pressure steam output mechanism for a steam oven. Background Technology

[0002] A steam oven, also known as an electric steamer, is a kitchen appliance that uses high-temperature direct-injection steam to cook food. It converts water into steam through a steam generator; some models can generate high-temperature steam within 10 seconds, reaching a maximum temperature of 300℃. The core operating mode includes a circulating convection system for even heating. This product offers two steam modes: normal steam (100-150℃) and high-temperature steam (200-250℃), suitable for vegetables, eggs, seafood, and meats. Some models are equipped with intelligent temperature control systems, 360-degree three-dimensional heating and circulating steam technology, and micro-pressure steaming function to ensure even heating and retention of moisture and vitamins. The inner pot is mostly made of 304 food-grade stainless steel, which has corrosion-resistant properties. Some models feature intelligent menu systems and automatic intermittent water filling devices, and support degreasing and salt reduction functions to maintain the original flavor of the food.

[0003] However, the existing steam ovens on the market are still based on traditional atmospheric pressure steam heating. No matter how much food is being cooked, it is necessary to turn on the high heat, which wastes energy. Existing steam ovens cannot monitor the internal pressure in real time and cannot detect whether the pressure is constant. Existing steam oven systems lack automatic adjustment of the steam power.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model discloses a multi-head adjustable constant pressure steam output mechanism for a steam oven, including a steam guide zone 1 and a steam oven panel 2. The steam oven panel 2 is located on the top of the steam oven, and food is cooked on the steam oven panel 2. The steam oven panel 2 is made of stainless steel and has the characteristics of strong oxidation resistance, strong corrosion resistance, and good heat resistance. The steam guide zone 1 is fixed to the bottom surface of the steam oven panel 2. The steam oven outputs steam and discharges condensate through the steam guide zone 1. The steam guide zone 1 includes a steam conveying part 11 and a drain part 12. The top of the steam conveying part 11 is welded to the bottom surface of the steam oven panel 2. The steam output from the steam oven panel 2 is introduced through the steam conveying part 11. The top of the drain part 12 is inserted into the bottom end of the steam conveying part 11. The condensate generated during the steam output process is discharged through the drain part 12. See details below. Figure 1 .

[0017] The steam transmission section 11 includes an inlet 111, a main pipe 112, a solenoid valve 113, a branch pipe 114, and a steam chamber 115. The inlet 111 is connected to the steam generator inside the steam oven. The main pipe 112 is welded to the top of the inlet 111, and the inlet 111 and the main pipe 112 are internally connected. Steam enters the main pipe 112 through the inlet 111. The solenoid valve 113 is located on both the front and rear sides of the main pipe 112. The branch pipe 114 is connected to the outside of the solenoid valve 113. The branch pipe 114 is opened and closed by the solenoid valve 113. The other end of the branch pipe 114 is welded to the top of the steam chamber 115. At one end, the diversion pipe 114 and the steam chamber 115 are connected internally. Steam is output to the steam oven panel 2 through the steam chamber 115. There are six solenoid valves 113, six diversion pipes 114, and six steam chambers 115. Each solenoid valve 113, diversion pipe 114, and steam chamber 115 are connected in sequence. The steam chambers 115 are arrayed at the bottom of the steam oven panel 2. Steam enters the steam chamber 115 under the control of the solenoid valves 113. The steam oven panel 2 includes a plate body 21 and a plate frame 22. The plate body 21 is "square". The plate frame 22 is arranged around the plate body 21, and the top surface of the plate frame 22 is higher than the top surface of the plate body 21. There are six steam holes 211 on the plate body 21, all located directly above the steam chambers 115. The steam holes 211 are controlled by the solenoid valves 113. A touch panel is installed on the front of the steamer. All six solenoid valves 113 are operated and controlled by the touch panel via wires. The system in the touch panel calculates the heating power based on the number of solenoid valves 113 that are open and the required steam pressure. After setting a constant pressure value, the heating power is calculated as a multiple of the number of solenoid valves 113 that are open, so that the steam pressure is consistent whether one steam hole 211 is opened or multiple steam holes 211 are opened. The opening and closing of the solenoid valves 113 can be controlled according to the chef's cooking needs to control the number of steam holes 211 that are open. Steam holes 211 that are not used for cooking can be closed individually, which saves energy and prevents the chef from accidentally getting burned.
