Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to an inner container structure of a steam oven. Background Art
[0002] Superheated steam has been widely used in food cooking and processing due to its high enthalpy value, which can make food heated evenly, heat quickly, retain the original flavor of food, and prevent the loss of vitamins. The working process of superheated steam oven can be mainly divided into two stages: superheated steam generation and steam delivery and release. Traditional superheated steam ovens rarely monitor the quality of superheated steam. The generation of superheated steam is usually accompanied by a high temperature environment. The high temperature environment of the steaming and baking chamber and the uncertainty of the steam volume lead to unsatisfactory steaming and baking effects; the temperature of superheated steam will begin to decrease after contacting the steaming and baking object. In order to ensure the quality of steaming and baking, it is necessary to continuously generate and release superheated steam, which consumes a lot of energy; the steaming and baking chamber is usually a closed space, which forms a high temperature environment under the influence of superheated steam. In this environment, long-term steaming and baking of food, especially meat products, will produce oil smoke, which contains carcinogens such as benzopyrene attached to the surface of food and cause harm to the human body.
[0003] In summary, traditional superheated steam ovens have the following disadvantages: (1) The generation and delivery of superheated steam are not monitored and the quality of superheated steam cannot be guaranteed; (2) The temperature of superheated steam drops after it acts on the steaming and baking object, and steam needs to be continuously generated, which is inefficient and causes uneven steaming and baking; (3) The enclosed steam action space produces fumes that adhere to the food and affect human health.

An air communicator 16 is arranged on the top of the other side wall of the second tank body 13, and a liquid level sensor 2 14 is arranged on the top of the second tank body 13.

[0041] In some specific embodiments, a superheated steam temperature sensor 31 is further provided at the outlet of the heat exchanger 32 .
[0042] In some specific embodiments, the outlet end of the heat exchanger 32 is also connected to a superheated steam delivery pipeline 30 , and the superheated steam delivery pipeline 30 respectively penetrates the first shell 1 and the second shell 2 and extends into the first shell 1 .
[0043] In some specific embodiments, a superheated steam nozzle 42 is disposed in the first shell 1 near the inner wall of the second shell 2 . An opening is disposed at one end of the superheated steam nozzle 42 , and the open end is connected to the superheated steam delivery pipeline 30 .
[0044] In some specific embodiments, a side wall of the superheated steam nozzle 42 is provided with a plurality of nozzles 43 at equal intervals.
[0045] In some specific embodiments, the output port disposed on the side wall of the second tank body 13 is connected to a pressurized water pump 18 through an output pipeline 17 , and the output end of the pressurized water pump 18 is connected to the spray gun 11 .
[0046] Specifically, the water purifier 19 is arranged on the water inlet pipeline 27 to ensure the water quality in the first tank body 4. The first tank body 4 ensures that its water storage capacity is within a certain range under the action of the liquid level sensor 24, and is heated under the monitoring of the water temperature sensor 26 and the pressure sensor 34 to ensure that the heating time is appropriate and the heating process is safe. The generated atmospheric pressure steam reaches the heat exchanger 32 through the atmospheric pressure steam delivery pipeline 36 as the electromagnetic valve 3 22 is opened. The output port of the heat exchanger 32 is provided with an overheated steam temperature sensor 31 to control the overheated steam to maintain a suitable temperature, and the output port position is also connected to the overheated steam temperature regulating pipeline 37 provided with the electromagnetic valve 23, and the delivery temperature is lower than the overheated steam. Normal pressure steam can adjust the temperature of superheated steam to a certain extent. The output port is connected to the superheated steam delivery pipeline 30, which is connected to the superheated steam nozzle 42. A large number of steam nozzles 43 are evenly distributed on one side of the superheated steam nozzle 42 to ensure the uniform release of superheated steam. The air communication device 16 arranged above the second tank body 13 ensures that the water inlet pipeline 1 27 and the water inlet pipeline 2 29 can be smoothly inflowed. The liquid level sensor arranged controls the water inflow. The output pipeline 17 connected to the right output port is provided with a pressurized water pump 18, and the end of the pressurized water pump 18 is connected to a spray gun 11. A cleaning block can be added to the front end of the pressurized water pump 18 so that the water sprayed by the spray gun 11 has a cleaning effect, which is convenient for cleaning the steaming and baking chamber 6. Finally, the bottom drain port of the second tank body 13 is connected to a drain port 35 controlled by a solenoid valve 6 38, so as to replace the clean water inside the second tank body 13.
[0047] Working principle: the control system drives the electromagnetic valve 1 28 and the electromagnetic valve 2 23 to open, and the clean water enters the water inlet pipe 1 27, flows through the water purifier 19, and finally reaches the input port of the first tank body 4. The purified water passing through the water purifier 19 enters the first tank body 4; as the clean water continues to enter the first tank body 4, the liquid level inside the first tank body 4 gradually rises. When the liquid level reaches the set upper limit, the liquid level sensor 1 24 arranged above the first tank body 4 will transmit the liquid level signal to the control system, and then the electromagnetic valve 1 28 and the electromagnetic valve 2 23 will be closed. At the same time, the first tank body 4 will heat the water in the device under the monitoring of the water temperature sensor 26 and the pressure sensor 34, and the inside of the heat exchanger 32 will also be heated, which is convenient for the subsequent heating work of the normal pressure steam;
[0048] When the pressure and temperature inside the first tank body 4 reach the set value, the pressure sensor 34 and the water temperature sensor 26 will send corresponding signals to the control system, thereby controlling the solenoid valve 20 to open, that is, the atmospheric pressure steam delivery pipeline 36. The atmospheric pressure steam generated by the first tank body 4 will be delivered to the heat exchanger 32 through the atmospheric pressure steam delivery pipeline 36. The atmospheric pressure steam will be heated into superheated steam in the heat exchanger 32. The superheated steam will enter the superheated steam delivery pipeline 30 through the output port of the heat exchanger 32 provided with the superheated steam temperature sensor 31. When the superheated steam passes through the output port of the heat exchanger 32, the superheated steam temperature sensor 31 will be connected to the superheated steam delivery pipeline 30. 1 will monitor the temperature of the superheated steam. If the temperature of the superheated steam is abnormal, the superheated steam temperature sensor 31 will transmit the corresponding temperature signal to the control system, thereby controlling the electromagnetic valve 3 22 to open, and the normal pressure steam generated in the first tank body 4 will control the connected superheated steam temperature regulating pipeline 37 through the electromagnetic valve 3 22 to regulate the superheated steam with abnormal temperature; the superheated steam reaches the superheated steam nozzle 42 through the superheated steam delivery pipeline 30, and the superheated steam nozzle 42 sprays the superheated steam through a large number of steam nozzles 43 equidistantly distributed on one side thereof, thereby acting on the steaming and grilling object of the grill inside the first shell 1.
[0049] After the steaming and baking work is finished, the electromagnetic valve 5 15 is opened by controlling the operation panel, and the clean water also enters the second tank body 13 through the water inlet pipe 29. The liquid level inside the second tank body 13 is monitored by the liquid level sensor 2 14. When the clean water level inside the second tank body 13 reaches the set height, the liquid level sensor 2 14 will transmit a signal to the control system to automatically control the closing of the electromagnetic valve 5 15 to stop the water inlet. The clean water in the second tank body 13 flows through the output port connected to the output pipe 17 on the right side of the second tank body 13, and flows through the pressurized water pump 18 with a cleaning block at the front end, providing a water source with cleaning effect for the spray gun 11. The sewage generated by using the spray gun 11 to clean the inside of the first shell 1 will flow to the sewage outlet below, so as to achieve the purpose of cleaning the inner cavity of the oven.
[0050] If it is necessary to discharge the clean water in the second tank body 13, a drain outlet 35 controlled by a solenoid valve 6 38 is provided below the second tank body 13, thereby completing the discharge of the clean water in the second tank body 13.
[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
