The utility model provides a humidifying electric oven 100, as shown in fig. 1, fig. 2 and fig. 4, which comprises an oven box body 500, a water tank 200, a water inlet pipe 400 and a fog generator 300, wherein the oven cavity 510 is arranged in the oven box body 500, the fog generator 300 is used for humidifying the oven cavity 510, the liquid in the water tank 200 enters the fog generator 300 through the water inlet pipe 400, and one end of the water inlet pipe 400 extends into the fog generator 300; the water tank 200, the water inlet pipe 400 and the mist generator 300 are enclosed together to form a chamber. Liquid in the water tank 200 can get into in the fog generator 300 for liquid in the fog generator 300 constantly increases, and when the liquid level in the fog generator 300 improved to the tip that stretches into the fog generator 300 that has not crossed inlet channel 400, because water tank 200 all the other all around all the same all with external intercommunication except that inlet channel 400, hydraulic pressure, the inside atmospheric pressure of water tank 200 of liquid in the fog generator 300 acted on down, make the inside remaining liquid of water tank 200 can't continue to flow out. When the liquid in the mist generator 300 is atomized by the mist generator 300 and is discharged out of the mist generator 300 in the form of mist, the liquid level in the mist generator 300 is lowered, and when the liquid does not sink into the end part of the water inlet pipe 400 extending into the mist generator 300, the liquid in the water tank 200 starts to flow into the mist generator 300 until the liquid level in the mist generator 300 is raised again to the end part of the water inlet pipe 400 extending into the mist generator 300, and the liquid level in the mist generator 300 can be automatically controlled by the reciprocating circulation. Compare in current oven that has the humidification function, the humidification electric oven 100 that this application provided can automatic control water level, saves the water resource, stops the water waste.

Specifically, as shown in fig. 4, the fog generator 300 includes an ultrasonic sheet 310, a reservoir 320 and a fog pipe 330, wherein the reservoir 320 is used for receiving the liquid from the water tank 200 and providing a certain liquid level; the ultrasonic sheet 310 is used for generating ultrasonic waves to atomize the liquid in the water storage tank 320; the fog water pipe 330 is disposed on the top of the fog water generator 300 and extends into the cavity 510 of the humidified electric oven 100. After being atomized, the liquid in the water storage tank 320 flows through the mist pipe 330 and enters the oven cavity 510. In addition to generating mist by ultrasonic vibration, the mist generator 300 may generate mist by other methods, such as heating and evaporation.

In other words, the water inlet pipe 400 and the water storage tank 320 should be properly arranged to increase the liquid level at a higher rate when the same amount of liquid is injected, thereby further saving water resources.

In some embodiments, as shown in fig. 2, in order to accelerate the mist in the mist generator 300 to enter the humidifying electric oven 100, a fan 520 is disposed below the mist generator 300, the mist can be accelerated to flow into the cavity 510 by the fan 520, and the dispersing effect in the cavity 510 is good. For the humidified electric oven 100 not provided with the fan 520, the mist is emitted by means of the mist water pipe 330 and the air flow inside the cavity 510.

In some of these embodiments, as shown in fig. 1 and 3, the water tank 200 is detachably connected to the oven case 500. Since the oven needs to process various foods, for some foods having requirements on humidity, such as bread, cake, etc., the water tank 200 can be connected to the oven body 500, and automatic water level control is performed to ensure the humidity in the oven cavity 510; for some food items requiring a dry environment, such as cookies, the water tank 200 may be removed to avoid excessive humidity in the cavity 510.

In the embodiment in which the water tank 200 is detachably coupled to the oven case 500, as shown in fig. 3, a water tank case 220 and a water tank holder 230 are further disposed between the water tank 200 and the oven case 500, the water tank case 220 corresponds to a cover of the water tank 200 for sealing the water tank 200, and the lift pin 210 is disposed at the center of the water tank case 220; the water tank base 230 is disposed on the oven body 500, and a channel for liquid circulation and a structure for pushing the top cover are disposed in the water tank base 230. The water tank sleeve 220 is connected with the water outlet, the water tank sleeve 220 is connected with the water tank seat 230, and the water tank seat 230 is connected with the oven body 500 through common threads or pipe threads, and the threaded connection realizes the detachable connection of the water tank 200 on the premise of ensuring the water tightness. Other common detachable sealed connections may also be used with the present invention. In addition, the cavity formed by the water tank 200 and the water inlet pipe 400 is provided with sealing elements such as sealing rings and the like which are commonly used for ensuring the sealing performance at the joints of the components.

In some of the embodiments, as shown in fig. 1, since the liquid in the water tank 200 needs to flow into the fog generator 300, the water tank 200 is usually disposed on the top of the humidified electric oven 100, and the liquid spontaneously flows downward into the fog generator 300 by its own weight, i.e., the water tank 200 needs to be disposed above the fog generator 300. The water tank 200, the water inlet pipe 400 and the fog generator 300 may be integrated into the oven body 500, so that the entire humidified electric oven 100 may have a more regular shape to save space; the water tank 200, the water inlet pipe 400 and the mist generator 300 may be disposed outside the water tank 200 without changing or with little change of the internal structure of the existing oven, and at the same time, the water tank 200 is easily disassembled.

The utility model provides a humidification electric oven 100 possesses following advantage at least:

a cavity is formed by the water tank and the water inlet pipeline, and the cavity is sealed or communicated with the fog generator by changing the water level in the fog generator, so that the automatic control of the water level in the fog generator is realized.
