Description

Technical Field

[0001] The invention belongs to the technical field of ovens, and in particular relates to an oven capable of performing steam assistance in a directional gear position. Background Art

[0002] With the popularization of oven use, people's functional requirements for ovens are not limited to the commonly used grilling and baking. Instead, they pursue healthier cooking methods. For example, adding steam assistance can reduce the loss of nutrients in food. After the oven is used, grease will adhere to the inner wall of the oven, causing trouble for subsequent cleaning. To address these pain points, the current existing solutions are mainly to add water to the oven without opening the door, which is low-cost and simple to operate.

[0003] In the existing water-adding scheme of the oven, the implementation method is to control the operation of each mode of the oven by a mechanical gear switch, and a separate water injection device is installed on the operation panel. The injected water is stored in an independent water tank, and the end of the water tank is connected to the bottom of the oven inner tank by a water pipe. In the water path leading to the bottom of the oven inner tank, an electromagnetic valve is installed to control the on-off of the water path, and there is no connection between the oven gear switch and the electromagnetic valve controlling the water path, so the water injection can be freely controlled in any state, which will lead to the hidden danger of misoperation. Misinjection of water in a gear mode that does not require water injection will also affect the normal use of the oven, bring a bad experience to users, and reduce the grade of the product. In addition, the amount of water injection cannot be quantitatively injected according to the usage of different modes, resulting in a decrease in the use effect. Summary of the invention

[0004] The object of the present invention is to provide an oven that can be steam-assisted in a directional position to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an oven capable of performing steam assistance in a directional gear, comprising:

[0006] An oven, wherein a door is hingedly connected to the surface of the oven and an instrument panel is provided on the top of the front end of the oven;

[0007] A power board, which is arranged in the oven and used to control the coordinated operation of each module in the oven. A multi-way switch is arranged in the oven and located on the instrument panel. A liquid expansion type thermostat is arranged on the instrument panel and located on one side of the multi-way switch.

[0008] A water tank is arranged in the oven, one end of the water tank is connected to a water pipe and a solenoid valve is arranged on the water pipe.

[0009] Preferably, a water tank is provided at the bottom of the oven, and the water outlet of the water pipe is connected to the water tank.

[0017] Preferably, the multi-way switch, liquid expansion thermostat, solenoid valve, cooling fan, oven light, sudden jump thermostat, rear fan, upper heating tube, rear heating tube, and bottom heating tube are all electrically connected to the power board.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention adds water through a directional gear mode, and water can be injected only at a specific gear, which can effectively avoid accidental water injection, reduce interference with the normal operation of the oven, improve user experience, and make the cooking process smoother. In addition, the amount of water injected can be controlled according to a specific program. When the adjustment knob is rotated to the specified gear, the power board receives a signal and activates the water injection button on the display operation panel to achieve precise control.

[0020] (2) The present invention uses DC12V direct current to control the solenoid valve, which reduces the voltage from the source. Even in a humid environment or when there is a water line failure, it can greatly reduce the possibility of leakage causing harm to the user, thereby ensuring user safety and allowing users to use it with confidence.

[0021] (3) When the adjustment knob is turned to the ECO position, the oven's heating mode changes intelligently. The program accurately controls the on and off time of the heating tube based on the temperature feedback from the liquid expansion thermostat. When the temperature does not reach the set value, the heating tube heats normally; when the set value is reached, the heating is turned off as a whole, avoiding energy waste caused by traditional continuous heating, reducing energy consumption, and saving electricity bills for users.

[0022] (4) The multi-way switch is associated with the electric control panel to change the traditional independent control mode. When the adjustment knob is rotated to the specified position, the power board receives the signal and activates the water filling button on the display panel to achieve precise control and realize the automatic water filling function through intelligent association.

[0040] The instrument panel 3 is provided with a water inlet 12, and the water inlet 12 is connected to the water tank 7 through a pipe. A cooling fan 13 is provided on the top of the oven 1, and the water inlet 12 is connected to the water tank 7 through a pipe, forming a complete water system. The water injected from the water inlet 12 can smoothly flow into the water tank 7 for storage.

[0041] An oven light 14 is disposed on the top of the oven 1 .

[0042] A display operation panel 15 is provided in the middle of the instrument panel 3 , and a jump-type temperature controller 16 is provided in the rear end of the oven 1 .

[0043] A rear fan 17 is provided at the rear end of the oven 1, and the rear fan 17 promotes air circulation inside the oven 1, so that heat is evenly distributed and the cooking effect is improved.

[0044] The rear end of the oven 1 is provided with an upper heating tube 18, a rear heating tube 19, and a bottom heating tube 20 in sequence. The layout of the three heating tubes can realize all-round heat supply, effectively avoiding the situation where food is partially burnt or undercooked, and improving the cooking effect.

[0045] A plurality of partition mounting frames 21 are connected to both sides of the oven 1, and partitions 22 are arranged inside the partition mounting frames 21. The partitions 22 are used together with the partition mounting frames 21 to flexibly divide the internal space of the oven 1 for cooking a variety of different types of food.

[0046] The instrument panel 3 is provided with two groups of adjustment knobs 23 .

[0047] The multi-way switch 5 , the liquid expansion thermostat 6 , the solenoid valve 9 , the cooling fan 13 , the oven light 14 , the sudden jump thermostat 16 , the rear fan 17 , the upper heating tube 18 , the rear heating tube 19 , and the bottom heating tube 20 are all electrically connected to the power board 4 .

[0048] In the water system of the oven that can be steam-assisted in a directional position, a water tank 7 stores water, which is connected to a water tank 10 inside the oven 1 through a water pipe 8, and a solenoid valve 9 is installed on the water pipe 8 to control the on-off of the water circuit. When the multi-way switch 5 is not in a specified position, the contact connected to the power board 4 is disconnected, the power board 4 does not receive a connection signal, the water filling touch button on the display operation panel 15 does not respond, the relay controlling the solenoid valve 9 is in a disconnected state, the water circuit is closed, and water cannot be filled. When the adjustment knob 23 is rotated to the specified position of the multi-way switch 5 When the corresponding contact is connected, the power board 4 activates the water filling touch button on the display operation panel 15 after receiving the signal. The user touches the button, and the signal is transmitted to the power board 4. The power board 4 controls the relay to be turned on, and the solenoid valve 9 is energized to open. The water in the water tank 7 flows into the water tank 10 inside the oven 1 along the water pipe 8 by gravity. The water filling program is pre-set. A small amount of water is injected for the first time, and steam is quickly generated by the initial high temperature of the oven 1. After that, the timer in the oven 1 controls the interval automatic water filling until the water volume required for the gear is reached to ensure a continuous and stable supply of steam.

[0049] like Fig. 9 As shown, when the adjustment knob 23 is rotated to the ECO position of the multi-way switch 5, the multi-way switch 5 is switched to the position 10, the P9 pin is connected, and the power board 4 wakes up the oven 1 to enter the ECO energy-saving mode. At this time, the heating mode of the oven 1 is changed from the traditional mechanical temperature control to the program-controlled intelligent heating. The program accurately controls the on-off time of the upper heating tube 18, the rear heating tube 19, and the bottom heating tube 20 according to the set temperature and the real-time temperature monitored by the liquid expansion thermostat 6. When the temperature is lower than the set value, the program controls the multiple heating tubes to continue heating; when the set value is reached, the program controls the multiple heating tubes to stop heating, and waits for the temperature to drop before starting heating again, so as to maintain the temperature in the oven 1 stable and reduce energy consumption;

[0050] and Fig. 9 The P3-3 pin is the wake-up connection pin for the water injection function, and the P8-8 pin is the ECO mode connection pin.
