Detailed Implementation

[0028] 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.

[0029] like Figure 1 As shown in the figure, the water tank ejection mechanism of the household appliance described in this embodiment of the present invention includes a water tank 100 and an ejection control module 200. The ejection control module 200 includes a base plate 201 and an elastic power component 202. The base plate 201 is used to install and fix it inside the household appliance. The water tank 100 is slidably connected to the base plate 201 and has two states: retracted and closed, and ejected and open. The elastic power component 202 is disposed on the base plate 201 and is used to drive the water tank 100 to slide and eject. A labyrinth locking structure is also provided between the base plate 201 and the water tank 100 to constrain the locking, ejection, and resetting of the water tank 100.

[0030] like Figure 1-6 As shown, the specific structure of the water tank ejection mechanism of the household appliance of this utility model can be as follows: the base plate 201 is installed and fixed on the household appliance by screws passing through the screw holes 212 thereon (of course, the base plate 201 can also be installed and fixed on the household appliance by a snap-fit ​​structure). The water tank 100 and the base plate 201 are slidably assembled and connected by a sliding groove 107 and a slider 211. More specifically, the bottom surface of the water tank 100 is provided with sliding grooves 107 on both sides, and the upper surface of the base plate 201 is provided with sliders 211 on both the left and right sides. During assembly, the sliders 211 on the left and right sides are slidably assembled in the sliding grooves 107 on the left and right sides, so that the water tank 100 can slide in and out and be assembled on the household appliance.

[0031] The elastic power component 202 is a coil spring, the outer end of which is fixed to the base plate 201. Specifically, the elastic power component 202 is preferably a constant force coil spring, with its outer end fixed to the front end of the upper surface of the base plate 201 to provide a constant force throughout the entire pop-out process of the water tank 100. A recessed cavity 102 is provided at the rear end of the bottom of the water tank 100. During assembly, the coil spring is placed in the recessed cavity 102. When the water tank 100 retracts and closes, the outer end of the coil spring is straightened and located in the gap between the base plate 201 and the bottom of the water tank 100. When the coil spring returns to its original position, it acts on the cavity wall of the recessed cavity 102, driving the water tank 100 to move to the pop-out state. Of course, the elastic power component 202 can also be a spring, with both ends of the spring connected to the base plate 201 and the water tank 100 respectively. When the water tank 100 retracts and closes, the spring is compressed, and when the spring returns to its original position, it drives the water tank 100 to pop out.

[0032] The maze locking structure includes a Z-shaped rod 206 and a maze-shaped groove 106. The maze-shaped groove 106 is disposed on the outer surface of the water tank 100. One end of the Z-shaped rod 206 is oscillatingly connected to the base plate 201, and the other end is movably connected to the maze-shaped groove 106. Specifically, the base plate 201 is provided with an oscillation hole 207, a limiting plate 208, and a limiting protrusion 209. One end of the Z-shaped rod 206 is rotatably mounted in the oscillation hole 207. The limiting plate 208 and the limiting protrusion 209 are separately disposed. The Z-shaped rod 206 is located between the limiting plate 208 and the limiting protrusion 209 and oscillates within the gap between the limiting plate 208 and the limiting protrusion 209. The maze-shaped groove 106 includes an inlet / outlet section 108, a locking section 109, and an ejection section 110 connected in sequence. A locking position 111 is provided at the connection between 09 and the pop-out section 110; when the water tank 100 is pressed inward to the retracted closed state, the other end of the Z-shaped rod 206 is locked on the locking position 111 through the guide-out section 108 and the locking section 109 in sequence, locking the water tank 100 in the retracted closed state. When the water tank 100 is pressed inward again, the other end of the Z-shaped rod 206 moves from the locking position 111 through the pop-out section 110 to the guide-out section 108, thereby unlocking the water tank 100, and popping out and opening under the action of the elastic power component 202 (coil spring).

[0033] The water tank pop-out mechanism described in this utility model can realize the inward closing and pop-out opening of the water tank 100. Moreover, it adopts an independent pop-out control module 200 to cooperate with the water tank 100, which simplifies the structure, improves the assembly efficiency of household appliances, facilitates maintenance and replacement, and has strong versatility, which is conducive to the transformation of existing household appliances.

[0034] like Figure 1-3 One end of the recess 102 (i.e. the end facing the pop-out control module 200) extends to the rear end face of the water tank 100, forming an opening 103. During assembly, the coil spring on the base plate 201 is inserted into the recess 102 through the opening 103, making assembly convenient.

[0035] Furthermore, the recessed cavity 102 preferably adopts an arc-shaped cavity, which is compatible with the coil spring, facilitating the positioning of the coil spring within the recessed cavity 102 and thus improving the stability of the water tank 100's pop-out movement. The arc-shaped bottom surface 104 of the arc-shaped cavity is provided with a raised rib 105 extending along the bottom surface. The coil spring abuts against the raised rib 105, reducing the friction between the coil spring and the water tank 100 and improving the smoothness of the water tank 100's retraction closing and pop-out opening.

[0036] For example Figure 1-6As shown, in a preferred embodiment of this utility model, a damping structure is further provided between the base plate 201 and the water tank 100, including a damper 203 and a rack 101. The damper 203 can be a unidirectional rotary damper, with a gear 205 mounted on its rotating shaft 204. The gear 205 meshes with the rack 101 and moves back and forth on the rack 101 as the water tank 100 slides. The damper 203 can be disposed on the base plate 201, and the rack 101 can be disposed on the water tank 100. The rack 101 can be integrally formed with the water tank 100 or assembled with it. Alternatively, the damper 203 can be disposed on the water tank 100, and the rack 101 can be disposed on the base plate 201 accordingly. By providing this damping structure, the user's feel when pushing the water tank 100 is improved, and damage caused by excessive force is avoided, making the water tank ejection mechanism more stable and reliable.

[0037] like Figure 1 As shown in Figures 2, 4-6, in another preferred embodiment of this utility model, the base plate 201 has two side plates 210 connected as one piece (preferably integrally molded, such as integrally injection molded). The two side plates 210 are respectively provided with a Z-shaped rod 206 and a damper 203. The elastic power component 202 is a coil spring, located in the middle of the base plate 201. A cavity 102 is provided in the middle of the rear end of the bottom surface of the water tank 100. A labyrinthine groove 106 and a rack 101 are respectively provided on the left and right sides of the cavity 102. During assembly, the coil spring is placed inside the cavity 102, and the other end of the Z-shaped rod 206 is movably connected to the labyrinthine groove 106. The gear 205 on the shaft 204 of the damper 203 meshes with the rack 101. By adopting this structure, the balance of forces during the inward and outward movements of the water tank 100 is improved, resulting in smoother and more stable movement.

[0038] The household appliance provided by this utility model can be a steam oven, a steam oven and fryer, a range hood, etc., and the household appliance is equipped with the above-mentioned water tank ejection mechanism.

[0039] 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.
