Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

As shown in fig. 1 to 3, the cooking apparatus may include a case 100, a water tank 300, a driving mechanism 400, a detector 500, and a controller 600.

The water tank 300 may employ various types of water tanks known in the art or that may occur in the future. The water tank 300 may be movably disposed on the case 100 between a stowed position and an extended position. The stowed position of the water tank 300 refers to an operating position of the water tank 300 when the water tank 300 may be located within the housing 100. In contrast, the extended position of the water tank 300 refers to a filling position of the water tank 300, in which case a filling port of the water tank 300 may be located outside the case 100, water may be directly filled into the water tank, or the water tank 300 may be removed.

The drive mechanism 400 may be used to push the water tank 300 out of the stowed position to the extended position. The driving mechanism 400 may include an oil cylinder, an air cylinder, etc., or may include a rotating motor to drive a rack gear, a cam, etc. Preferably, as shown in fig. 1-2, the drive mechanism 400 may comprise a linear motor. The linear motor has the advantages of simple structure, small size, quick response, high efficiency, low noise and the like.

The detector 500 may be provided on the water tank 300. The detector 500 may be used to detect the amount of water in the water tank 300. The detector 500 may include one or more of a pressure switch, a level switch, and the like. Depending on the detector 500, the detector 500 may be disposed at various positions of the water tank 300 so that the detector 500 can perform its function. For example, when the detector 500 is a pressure switch, the detector 500 may be disposed at the bottom inside the water tank. Since the higher the water level, the greater the water pressure, the pressure switch can detect the amount of water in the water tank 300 according to the water pressure generated by the water in the water tank. When the detector 500 is a level switch, the detector 500 may be disposed at a side of the water tank 300. The level switch may detect the amount of water in the water tank 300 according to the pressure of water generated from the water in the water tank. The pressure switch and the level switch may be provided with a plurality of detection values so that the value of the amount of water in the detection water tank 300 is accurate. Preferably, the detector 500 may include one or more of a pressure sensor and a liquid level sensor. The pressure sensor and the liquid level sensor can continuously detect the water amount in the water tank 300, and the detected numerical value is more accurate.

The controller 600 may be located at any suitable location within the enclosure 100. The controller 600 may be electrically connected to the driving mechanism 400 and the detector 500, respectively.

The principles of the present invention will now be described in the preferred embodiment illustrated in figures 1-3. Wherein the driving mechanism 400 includes a linear motor and the detector 500 includes a pressure sensor.

The pressure sensor may detect the amount of water within the water tank 300 when the water tank 300 is in the stowed position. When the controller 600 receives the information on the amount of water in the water tank 300 detected by the pressure sensor, it controls the linear motor to adjust its pushing speed, i.e., the pushing speed of the linear motor push rod. The amount of water in the water tank 300 may be inversely related to the pushing speed of the linear motor push rod, which may be set according to the user's usage habit or set at the time of factory shipment. Since the water tank 300 needs to be taken out and cleaned frequently, the push rod of the linear motor is not mechanically connected with the water tank 300, and the push rod only contacts the water tank 300 so as to push out the water tank 300, so that the water tank 300 can be taken out and cleaned conveniently. When the water tank 300 needs to be filled with water or the water tank 300 is washed, the controller 600 may control the pushing speed of the linear motor push rod to be decreased if the amount of water in the water tank 300 is small or even exhausted. The push rod of the linear motor may push the water tank 300 out of the stowed position to the extended position at a low extension speed. Thus, when the water tank 300 is extended, the water tank 300 is not moved out of the tank body 100 due to the light weight of the water tank 300 and the pushing speed of the push rod is too fast. When the water tank 300 is pushed out to the extended position, a user may open the water tank cap plug 310, and fill water to a water filling port under the water tank cap plug 310; or the user may take the water tank 300 out for cleaning. At this time, the push rod of the linear motor can be located at the maximum extending position and then retract by itself. The water tank 300 may be manually pushed back to the stowed position when the user fills or has finished cleaning. When filling water into the water tank 300 or washing the water tank 300, the controller 600 may control the push-out speed of the linear motor push rod to be increased if the amount of water in the water tank 300 is large. The push rod of the linear motor may push the water tank 300 out of the stowed position to the extended position at a high extension speed. Therefore, when the water tank 300 extends out, the extending time is reduced, and the working efficiency is improved.

With this arrangement, the amount of water in the water tank 300 can be matched to the pushing speed of the driving mechanism 400 by itself. No matter how much water is in the water tank 300, the water tank 300 can have a stable extension speed, and the noise when the water tank 300 is extended is low. The safety performance of the cooking device is improved, the use efficiency is improved, and the experience feeling is good.

Preferably, as shown in fig. 1-2, the cooking appliance may further include a micro switch 700. The micro-switch 700 may be implemented with various types of micro-switches known in the art or that may occur in the future. The micro switch 700 may be disposed at the rear of the water tank 300. The rear of the water tank 300 refers to a side farther from the user, and thus the front of the water tank 300 is closer to the user, as is the case with the case 100. The water tank 300 may activate the micro switch 700 when in the stowed position. The micro switch 700 may be electrically connected to the controller 600. The rear wall of the water tank 300 may trigger the micro switch 700 when the water tank 300 is in the stowed position. The controller 600 may control the driving mechanism 400 to push the water tank 300 from the retracted position to the extended position in response to an electrical signal from the microswitch 700. Meanwhile, the controller 600 may control the water pump to pump water from the water tank 300 in response to an electric signal triggered by the micro switch 700, so as to prevent the water pump from idling when the water tank 300 is in the non-retracted position. Therefore, by arranging the micro switch 700, it can be ensured that the driving mechanism 400 and other components can normally work when the water tank 300 is located at the storage position, thereby reducing the possibility of misoperation, prolonging the service life of the driving mechanism 400 and other components, and reducing the energy consumption of the cooking device.

Further, the cooking appliance may further include a display screen (not shown). The display screen may be provided on the panel 110 of the cabinet 100. The display screen may be disposed on the panel 110 of the case 100 in any manner, for example, the display screen may be disposed on the panel 110 of the case 100 by means of a threaded connection, welding, adhesion, or the like. The display screen may be electrically connected to the controller 600. The display screen may display the activation state of the microswitch 700. That is, the display screen may have the activated and/or deactivated states of the micro-switch 700 displayed thereon. Therefore, a user can visually observe whether the water tank 300 is correctly positioned at the retracting position, and when the position of the water tank 300 is not in place, the user can timely adjust the position of the water tank 300, so that the man-machine interaction is better.

Illustratively, as shown in fig. 1-2, the cooking mechanism may further include a guide mechanism 200. The guide mechanism 200 may be provided on the case 100. The water tank 300 may be movably coupled to the guide mechanism 200 between a stowed position and an extended position. The guide mechanism 200 may be disposed on the case 100 in any manner, for example, the guide mechanism 200 may be disposed on the case 100 by means of a threaded connection, welding, adhesion, or the like. The guide mechanism 200 may have a variety of configurations, such as a rail, rack and pinion, and the like. The guide rail has the advantages of simple structure, low friction resistance and the like. By providing the guide mechanism 200, the water tank 300 can be guided and protected while the water tank 300 moves between the stowed position and the extended position.

Alternatively, as shown in fig. 1-2, the guide mechanism 200 may include a tank housing. The water tank case may not only accommodate the water tank 300 but also define a moving direction of the water tank 300. The front face of the tank case may have an opening 230. The tank case may include a top wall, a bottom wall, a left side wall, and a right side wall, which define four moving directions of the water tank 300. The water tank 300 may protrude from the opening 230 out of the water tank housing when the water tank 300 is moved to the protruding position along the water tank housing. The front end of the tank case may be fixed to the back of the panel 110 of the cooking appliance. The cistern housing may also include a rear wall. The rear wall may have a first through-hole 210 and a second through-hole 220. The driving mechanism 400 may push the water tank 300 through the first through hole 210. The micro switch 700 may protrude into the tank case through the second through hole 220. Thus, the guide mechanism 200 is simple in the form of a tank case, and can also perform the function of integrally protecting the tank.

For example, as shown in fig. 1-2, the cooking appliance may further include a mounting bracket 800. The mounting bracket 800 may be positioned at the rear of the guide mechanism 200 and fixed to the case 100. The drive mechanism 400 and the microswitch 700 may be disposed on the mounting bracket 800. Preferably, the mounting bracket 800 may be fixed to the case 100 by a screw connection. Preferably, the driving mechanism 400 and the micro switch 700 may also be provided on the mounting bracket 800 by a screw connection. Through setting up erection support 800, make actuating mechanism 400 and micro-gap switch 700 good heat dissipation, operational environment promotes long service life.

Preferably, as shown in fig. 1-2, the mounting bracket 800 and the guide mechanism 200 may be integrally connected. Therefore, the error of the distance between the water tank 300 and the microswitch 700 can be reduced, the microswitch 700 is ensured to have better triggering effect when the water tank 300 is positioned at the retracting position, the assembly process of the cooking device during mass production is simplified, and the consistency of the cooking device is good.
