In addition, the control panel assembly 16 in the present application may be used not only as a display interface but also as an operation interface. In this case, since the control panel assembly 16 is disposed at the front side of the cabinet 1, when a user is at the front side of the steam oven 100, the operation parameters of the steam oven 100 may be set through the control panel assembly 16, and the operation state of the steam oven 100 may be observed through the control panel assembly 16. In other embodiments of the present application, the control panel assembly 16 may include a plurality of touch buttons, and the operation state, the heating temperature, the operation time, and other functions of the steam oven 100 may be conveniently adjusted by touching the touch buttons.

In other embodiments of the present application, a plurality of knobs and buttons may be further installed on the control panel assembly 16 for adjusting functions such as an operation state, a heating temperature, and an operation time of the steam oven 100. This is not a limitation of the present application.

In addition, in other embodiments of the present application, the two sides of the water tank box 7 may be opened with a position-avoiding opening 714 as shown in fig. 11, since the control panel assembly 16 may be driven so as to make the control panel assembly 16 move away from or close to the water tank box 7. Thus, the reserved clearance 714 can leave a mechanical movement space for the driving mechanism for driving the control panel assembly 16 to move. In this way, the water tank case 7 does not affect the movement of the control panel assembly 16.

In some embodiments of the present application, when the second water tank 9 is applied in the steam oven 100, a water level detection device needs to be disposed to detect the water level in the second water tank 9, otherwise, if there is no water level detection device, when the water flow in the second water tank 9 is full, a safety hazard may be caused. In some embodiments of the present application, the water level detection device may be a combination of a reed switch 17 and a magnetic float 18. As shown in fig. 14, the magnetic buoy 18 is disposed in the second water tank 9, and the reed switch 17 is mounted on an outer surface of the water tank box 7 away from the second opening 7012 (see fig. 15) and is configured to be opened or closed under the action of a magnetic field generated by the magnetic buoy 18.

The reed switch 17 mentioned in this application may also be called reed switch or magnetic reed switch, and is a special switch that is magnetically sensitive. The operating principle of the reed pipe 17 is as follows: the two pieces of magnetizable reeds overlapped at the end points are sealed in a glass tube, the distance between the two reeds is only about a few microns, the glass tube is filled with high-purity inert gas, when the two reeds are not in contact with each other and an external magnetic field enables the positions of the end points of the two reeds to generate different polarities, and as a result, the two reeds with different polarities attract each other and are closed. The reed switch 17 can be made into a switching assembly of a very small size and volume, and the switching speed is very fast and has very excellent reliability.

Thus, a change-over switch is formed, when the magnetic part is close to the reed pipe 17 or the magnetic field formed by electrifying the coil wound on the reed pipe 17 magnetizes the reed, the contact part of the reed is attracted by the magnetic force, when the attraction force is larger than the elastic force of the reed, the normally open contact is attracted, and when the magnetic force is reduced to a certain degree, the contact is opened by the elastic force of the reed.

In this case, as shown in fig. 14, the reed switch 17 may be installed above the tank case 7, and thus, the magnetic float may be installed in the second tank 9 to be elevated according to the water level in the second tank 9 (the position of the water is indicated by the wavy line in fig. 14). Therefore, when the water level in the second tank 9 is at a low level (when the second tank 9 is initially used, there is little or no water), the magnetic float 18 is at a low level (see fig. 14), and at this time, the magnetic float 18 is far from the reed pipe 17, and the contact portions of the reeds are not sufficiently magnetized, so that the two reeds are not closed by contact. When the water level in the second water tank 9 continues to rise to the high level, the magnetic buoy 18 is also at the high level along with the water level, at the moment, the magnetic buoy 18 is closer to the reed pipe 17, the reed pipe 17 is influenced by the magnetic buoy 18 and is under the magnetic field effect of the magnetic buoy 18, the contact parts of the two reeds are attracted by magnetic force, when the attraction force is greater than the elastic force of the reeds, the normally open contact is attracted, the reed pipe 17 is conducted, and then the control panel assembly 16 receives a conducting signal of the reed pipe 17 to indicate that a user pours water.

In other embodiments of the present application, a reed switch 17 may be installed on an outer surface of the tank box 7 away from the first opening 7011, and as shown in fig. 16, the reed switch 17 may be close to the bottom of the tank box 7, and a magnetic float 18 may be disposed in the first tank 8, and the reed switch 17 may be opened or closed by a magnetic field generated by the magnetic float 18.

In this way, the magnetic float is provided in the first water tank 8 so as to be able to rise and fall in accordance with the water level in the first water tank 8. Therefore, when the first tank 8 is initially used, the amount of purified water in the first tank 8 is large (see fig. 16), and therefore, when the water level in the first tank 8 is high, the magnetic float 18 is also high along with the water level, and at this time, the magnetic float 18 is far from the bottom reed pipe 17, and the contact portions of the reeds are not subjected to sufficient magnetic force, so that the two reeds do not come into contact with each other and close. When the steam oven 100 is continuously used, the water amount in the first water tank 8 can be gradually reduced, when the water level in the first water tank 8 is at a low level, the magnetic buoy 18 is at a low level, at the moment, the magnetic buoy 18 is only close to the reed pipe 17, the reed pipe 17 is influenced by the magnetic buoy 18 and is under the magnetic field action of the magnetic buoy 18, the contact parts of the two reeds can be attracted by magnetic force, when the attraction force is greater than the elastic force of the reeds, the normally open contact can be attracted, so that the reed pipe 17 is conducted, and then the control panel assembly 16 receives a conducting signal of the reed pipe 17 to indicate a user to fill water.

In other embodiments of the present application, the reed switch 17 may be installed only on the outer surface of the tank box 7 away from the second opening 7012, and a flow meter may be installed on the water pipe communicating with the first tank 8, so that the water stored in the first tank 8 can be observed through the flow meter.

In some embodiments of the present application, the second water tank 9 is used to recover waste water such as condensed water, since the first water tank 8 provides clean water for the steam oven 100. Since most of the steam in the steam oven 100 is absorbed by the food, the amount of waste water in the second water tank 9 is small, and the volume in the first water tank 8 can be set larger than the volume of the second water tank 9, rather than simply two identical volumes, so that the use space of the steam oven 100 can be optimized.

In order to detect whether the above-mentioned first and second water tanks 8 and 9 are mounted in place in the water tank box 7, a steam oven 100 according to an embodiment of the present invention may further include a first micro switch 19 and a second micro switch 20 as shown in fig. 15. A first through hole 715 is formed on a side of the water tank box 7 away from the first opening 7011 (not shown in fig. 15), and a second through hole 716 is formed on a side of the water tank box 7 away from the second opening 7012 (not shown in fig. 15). The first microswitch 19 is mounted on the outer surface of the water tank box 7 away from the first opening 7011, and the first microswitch 19 is abutted against and closed with the exposed part of the first water tank 8 at the first through hole 715. The second microswitch 20 is mounted on the outer surface of the tank case 7 away from the second opening 7012, and the second microswitch 20 is adapted to be closed in abutment with the portion of the second tank 9 exposed at the second through hole 716.

When the first water tank 8 and the second water tank 9 in fig. 13 apply force to the action reed of the first micro switch 19 or the second micro switch 20, the action reed moves to a critical point to generate instantaneous action, so that the movable contact at the tail end of the action reed is quickly connected with or disconnected from the fixed contact. When the acting force of the first water tank 8 and the second water tank 9 is removed, the action reed generates reverse action force, and the reverse stroke of the transmission element reaches the action critical point of the reed, and then the reverse action is instantly finished.

In this case, as shown in fig. 17, after the first water tank 8 is put into the tank case 7 and mounted in place, the first water tank 8 may touch the first micro switch 19 at the first through hole 715, so that the position of the main body of the first water tank 8 may be accurately detected in real time. When the second water tank 9 is put into the water tank box 7 and is installed in place, the second water tank 9 can touch the second micro switch 20 at the second through hole 716, so that the position of the main body of the second water tank 9 can be accurately detected in real time. Therefore, whether the first water tank 8 and the second water tank 9 are placed in place or not can be detected, and meanwhile, after the first water tank 8 or the second water tank 9 is taken out, the opening and closing of the steam oven 100 can be controlled through the opening and closing conditions of the micro switch by the steam oven 100, so that the electric components are protected.

The above-mentioned mounting of the first microswitch 19, the second microswitch 20 and the reed switch 17 and the water box case 7 is exemplified below, for example, in some embodiments of the present application, the steam oven 100 may further include a bearing component 717 as shown in fig. 18, an outer surface of the water box case 7 away from the first opening 7011 and the second opening 7012 is provided with the bearing component 717, and the bearing component 717 is connected with the water box case 7. Wherein the first micro switch 19, the second micro switch 20 and the reed switch 17 are mounted on the carrier 717. Specifically, the bearing assembly 717 may include a positioning column 7171 and a buckle 7172, wherein the positioning column 7171 is disposed on both the outer surface of the water tank box 7 away from the first opening 7011 and the outer surface of the second opening 7012, and the positioning column 7171 is connected to the water tank box 7. The outer surface of the water tank box 7 far away from the first opening 7011 and the outer surface of the second opening 7012 are both provided with a buckle 7172, and the buckle 7172 is connected with the water tank box 7. The first microswitch 19, the second microswitch 20 and the reed pipe 17 are connected with the positioning column 7171 in an inserting mode and clamped with the buckle 7172.

Specifically, as shown in fig. 19, the reed pipes 17 may each be fixed by two positioning columns 7171 and two snaps 7172. In this case, during installation, the positioning hole and the positioning column 7171 can be made to correspond, and then the reed pipe 17 is pressed, so that the buckles 7172 can be slightly deformed, and the reed pipe 17 can be clamped between the two buckles 7172. The bearing component 717 is not only simple in structure, but also easy to operate when installing the reed switch 17.

Similarly, as shown in fig. 20, the first microswitches 19 may be fixed by two positioning posts 7171 and two buckles 7172. In this case, during installation, the positioning hole may correspond to the positioning post 7171, and then the first micro switch 19 is pressed, so that the fasteners 7172 may be slightly deformed, and the first micro switch 19 may be clamped between the two fasteners 7172. The second microswitch 20 is mounted in the same manner as the first microswitch 19 and will not be described further here.

The second microswitch 20 can abut against the second tank 9 so that the first microswitch 19 can abut against the first tank 8. In other embodiments of the present application, a steam oven 100 of the present application may further include a carrier plate 718 as shown in fig. 20. The side wall of the bearing plate 718 may be vertically connected to the water tank box 7, so that a certain bearing space is formed at the upper portion of the bearing plate 718, and the positioning column 7171 and the buckle 7172 mentioned above may be connected to the upper portion of the bearing plate 718, so that the actuating reed of the first micro switch 19 can face one side of the first through hole 715 of the water tank box 7. In this case, a portion of the first water tank 8 on the side of the first through-hole 715 may abut against the action spring at the first through-hole 715 to trigger the first micro switch 19. Similarly, the second microswitch 20 can also be connected by the bearing plate 718, and the details are not repeated herein.

To facilitate the installation of the first water tank 8 and the second water tank 9, the steam oven 100 of the present application may further include a first limiting bar 719 and a second limiting bar 720 as shown in fig. 21, where the first limiting bar 719 is disposed in the first accommodating cavity 702 and connected to the water tank box 7. The second position-limiting strip 720 is disposed in the first accommodating cavity 702 and connected to the water tank box 7, and a gap is formed between the first position-limiting strip 719 and the second position-limiting strip 720. As shown in fig. 22, a convex strip 21 is arranged on the outer surface of the bottom of the first water tank 8, and the convex strip 21 is clamped in the gap between the first limiting strip 719 and the second limiting strip 720.

In this way, the first stopper 719 and the second stopper 720 are provided at the bottom of the first accommodating chamber 702, and the protruding strip 21 may be provided at the bottom of the first tank 8. In this case, when the first water tank 8 and the second water tank 9 are installed in the water tank box 7, the protruding strip 21 at the bottom of the first water tank 8 may be clamped between the first stopper 719 and the second stopper 720. Therefore, the combination structure of the first stopper 719, the second stopper 720 and the protruding strip 21 can play a role in guiding when the first tank 8 is mounted, preventing a left-right deflection. And, after first water tank 8 installed in place, the integrated configuration of first spacing 719, second spacing 720 and sand grip 21 can play limiting displacement to first water tank 8 in water tank box 7 for first water tank 8 is more stable in water tank box 7.

Similarly, the first stopper 719 and the second stopper 720 may be provided in the second receiving cavity 703, and the bottom of the second tank 9 may be provided with a rib 21 according to the first tank 8 shown in fig. 22. This application is not repeated.

In other embodiments of the present application, as shown in fig. 21, in the second accommodating chamber 703, a distance a between the first spacing strip 719 and the second spacing strip 720 on a side close to the second opening 7012 may be greater than a distance b between the first spacing strip 719 and the second spacing strip 720 on a side away from the second opening 7012. In this case, it may be more convenient for the above-mentioned protruding strip 21 to be inserted between the first stopper 719 and the second stopper 720. And the convex strip 21 can have a certain fault-tolerant space between the first limiting strips 719 and the second limiting strips 720, so that the convex strip 21 cannot be clamped between the first limiting strips 719 and the second limiting strips 720 due to errors generated by the distance between the first limiting strips 719 and the second limiting strips 720. Similarly, in the first accommodating cavity 702, the first limiting strip 719 and the second limiting strip 720 may be disposed in the second accommodating cavity 703.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
