[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] like Figure 1-4 As shown in the figure, the water tank of the steam oven with a shared water tank according to the embodiment of the present invention includes a water tank body 1. The water tank body 1 has a first water tank 2 and a second water tank 3 that are isolated from each other. The first water tank 2 and the second water tank 3 are preferably arranged in a top-to-bottom arrangement so that the shape of the water tank is more suitable for installation in the narrow space inside the steam oven.

[0024] The first water tank 2 of this invention serves as a shared water tank, which can be used alternately for storing water or cleaning fluid, and is connected to the water inlet 4, cleaning fluid inlet 5, and outlet 6 provided on the water tank body 1; the second water tank 3 is connected to the wastewater inlet 7 and wastewater outlet 8 provided on the water tank body 1. Thus, by designing a shared water tank (first water tank 2), the following advantages are achieved: firstly, the volume of the water tank is reduced, lowering the space limitations for application on equipment and improving versatility; secondly, the size of the water tank is maximized, increasing its capacity and ensuring sufficient water and cleaning fluid for steaming, baking, and cleaning, thereby improving the efficiency of steaming, baking, and cleaning; and thirdly, the structure of the water tank is simplified, reducing processing difficulty and cost.

[0025] Furthermore, in order to achieve a "flood prevention" effect between the water inlet 4 and the cleaning fluid inlet 5 on the basis of a shared water tank, the water tank body 1 of this utility model is also provided with a flood prevention liquid inlet structure. The flood prevention liquid inlet structure is located on the top of the first water tank 2 and can be integrated with the water tank body 1 (for example, the flood prevention liquid inlet structure is integrally injection molded on the top of the water tank body 1 or ultrasonically welded to the top of the water tank body 1), or it can be detachably assembled with the water tank body 1 (for example, the flood prevention liquid inlet structure is assembled on the top of the water tank body 1 by a snap-fit ​​method and the two are sealed together). The flood prevention liquid inlet structure includes a flood prevention buffer part 9, a water inlet 4, and a cleaning fluid inlet 5. The flood prevention buffer part 9 has a buffer cavity 10 inside, and the width of the buffer cavity 10 in direction A is 10-25mm. To further improve flood control performance, the width of the buffer cavity 10 in direction A is preferably 10-15 mm; the lower end of the buffer cavity 10 is connected to the first water tank 2, and the water inlet 4 and the cleaning fluid inlet 5 are provided on two opposite outer surfaces of the flood control buffer part 9 in direction A, and are connected to the buffer cavity 10 and are staggered. Preferably, the water inlet 4 and the cleaning fluid inlet 5 are staggered in both the vertical and horizontal directions.

[0026] In addition, in order to achieve automated control of the water tank, the water tank of this utility model is provided with an inlet valve 17, a first pneumatic pump 18, a second pneumatic pump 19, and a drain pump 20 in sequence at the water inlet 4, cleaning fluid inlet 5, liquid outlet 6, and wastewater outlet 8. The first pneumatic pump 18 and the second pneumatic pump 19 are preferably diaphragm pumps, and the drain pump 20 is preferably an impeller pump. The inlet valve 17, the first pneumatic pump 18, the second pneumatic pump 19, and the drain pump 20 are connected to the circuit board of the steaming and baking equipment.

[0027] like Figure 2-4 As shown, the water tank body 1 is assembled from a bottom shell 1a and a top cover 1b. The bottom shell 1a is integrally formed with a first water tank 2, a second water tank 3, a water inlet 4, a cleaning fluid inlet 5, a liquid outlet 6, a wastewater inlet 7, a wastewater outlet 8, a flood control buffer section 9, and a buffer cavity 10. When the top cover 1b is assembled with the bottom shell 1a to form the water tank body 1, the top cover 1b covers the first water tank 2, the second water tank 3, and the buffer cavity 10. The structural design is reasonable and simple, meets the requirements of existing production processes, and reduces the difficulty of production.

[0028] For example Figure 1-4 As shown, the top of the flood control buffer section 9 is also provided with an air hole 11. The air hole 11 is connected to the internal buffer chamber 10 and is connected to an air pipe so that when water and cleaning liquid such as lemon water are introduced into the first water tank 2, the air inside the first water tank 2 is discharged, and when water and cleaning liquid are output from the first water tank 2, air is introduced into the first water tank 2 through the air pipe and air hole to regulate the air pressure inside the first water tank 2 and ensure normal operation.

[0029] like Figure 1-3 As shown, the water tank body 1 is also equipped with a non-contact water level sensor 12 and a mechanical float water level sensor 13. The non-contact water level sensor 12 includes a first capacitive sensing element 14, a second capacitive sensing element 15, and a control circuit board 16. The first capacitive sensing element 14, the second capacitive sensing element 15, and the control circuit board 16 are all disposed on the outer surface of the water tank body 1, with the first capacitive sensing element 14 and the second capacitive sensing element 15 facing the upper and lower ends of the first water chamber 2, respectively, and connected to the control circuit board 16. The mechanical float water level sensor 13 is disposed inside the first water chamber 2, with its signal end extending and fixed from the top of the first water chamber 2, and connected to the control circuit board 16. The control circuit board 16 is connected to the circuit board of the steaming and baking equipment. Thus, when the water tank of the steaming and baking equipment of this invention is working, the first water chamber 2 is detected by both the non-contact water level sensor 12 and the mechanical float water level sensor 13, improving the reliability of water level detection and thereby enhancing the control performance of the water tank.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
