Description

Technical Field

[0001] This utility model relates to the technical field of drawers, and in particular to the technical field of drawer damping switches. Background Technology

[0002] As an indispensable household appliance in modern families, washing machines have undergone continuous evolution in function and technology to meet users' needs for washing effect and ease of operation. In the design of washing machines, the dispenser is a key component, which is responsible for dispensing detergents such as laundry powder, liquid detergent, or fabric softener during the washing process, thereby ensuring that the detergent dissolves and works at the appropriate time and water volume. Traditional dispensers usually adopt a drawer-type design, allowing users to add detergent by pushing and pulling the drawer, such as the washing machine drawer box with announcement number CN2895489Y, the front-loading washing machine detergent drawer box with announcement number CN2832875Y, and the washing machine and its drawer box with announcement number CN205329368U.

[0003] However, existing dispensers with a drawer-type structure have some inconveniences in use; users not only need to apply a certain amount of force to push the drawer inward when closing it, but also need to pull the drawer out fully when opening it; in other words, the drawer cannot pop out on its own, which makes operation relatively laborious (the user experience is not good), especially when the drawer has not been used for a long time or has become stuck due to a humid environment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an automatic drawer pop-out device for dispensers, which can achieve automatic drawer pop-out using a mechanical power storage design.

[0005] To achieve the above objectives, this utility model proposes an automatic drawer ejection device for a dispenser, comprising a device body. The device body can store force through an elastic storage mechanism as the drawer is pushed into the outer shell. The elastic storage mechanism can also actively push the drawer out of the outer shell using elastic force when the drawer is released.

[0006] Preferably, the main body of the device has a damper that can be coupled to the elastic energy storage mechanism and limit the sliding speed of the drawer.

[0007] Preferably, the elastic energy storage mechanism is a spring-loaded spring that can be wound around the drive shaft inside the sealing box, with one end of the drive shaft extending out of the sealing box and connected to a damper.

[0008] Preferably, the sealing box has a raised dot on the side that is in close contact with the outer shell.

[0009] Preferably, the outer casing has a flange that can abut against the sealing box to restrict the device body from leaving the casing.

[0010] Preferably, the box is composed of a detachably connected upper cover and a lower cover. The upper cover has an opening that connects the box cavity to the outside and faces the drive shaft. The drive shaft passes through the lower cover along the cover hole.

[0011] Preferably, the drive shaft is indirectly connected to the lower cover via a shaft ring, and a passive shaft with a spacer sleeve is integrally provided on the lower cover. One end of the spring is fixed to the spacer sleeve, and the other end is fixed to the shaft ring after being wound around the spacer sleeve several times.

[0012] Preferably, the damper is inserted into the drawer along the socket.

[0013] Preferably, the system also includes a transmission mechanism located between the housing and the drawer, which converts the internal thrust applied by the user onto the drawer into a rotational force that drives the drive shaft to rotate.

[0014] Preferably, the transmission mechanism includes a rack and a gear, the rack being installed inside the housing and parallel to the direction in which the drawer enters and exits the housing, and the gear being sleeved outside the drive shaft and meshing with the rack.

[0015] The beneficial effects of this utility model are:

[0016] 1) By adding a device body with an elastic energy storage mechanism between the outer shell and the drawer of the dispenser, on the one hand, the elastic energy storage mechanism can store energy simultaneously as the drawer is pushed into the outer shell, and on the other hand, the elastic energy storage mechanism can actively push the released drawer out of the outer shell using elastic force, thereby simplifying the user's operation steps, improving the convenience of use, and enhancing the reliability of the product.

[0017] 2) By adding a damper to the main body of the device and connecting the damper to the drawer along the socket, the damper can slow down the movement speed of the drawer when it enters and exits the outer shell (so that the drawer can close and open more smoothly), avoiding damage to the drawer and its surrounding components due to impact, and effectively extending the service life of the device.

[0018] 3) By adding a transmission mechanism consisting of a rack and pinion and a gear between the outer shell of the dispenser and the drawer, and using a spring as an elastic storage mechanism, the meshing between the rack and pinion can be used to make the gear rotate and pull the spring as the drawer enters the outer shell, thereby automatically storing a portion of the internal thrust applied by the user to the drawer in the spring.

[0019] 4) Through the meshing transmission between gears and racks, combined with the elastic storage of the spring, this device can provide a longer pop-out stroke compared to the traditional slide-type pop-out mechanism (the distance the drawer pops out can be long enough, without being restricted by the structure, so that the drawer can be completely separated from the shell or reach the maximum extension position), thereby significantly improving the convenience and experience of user operation.

[0020] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0030] See Figures 1 to 8The present invention relates to an automatic drawer ejection device for a dispenser, comprising a device body 11. The device body 11 can store force through an elastic storage mechanism as the drawer 3 is pushed into the outer shell 2. The elastic storage mechanism can also actively push the drawer 3 out of the outer shell 2 using elastic force when the drawer 3 is released.

[0031] The main body 11 of the device has a damper 114 that can be coupled to the elastic energy storage mechanism and limit the sliding speed of the drawer 3.

[0032] The elastic energy storage mechanism is a spring 113 that can be wound around the drive shaft 111 inside the sealed box. One end of the drive shaft 111 extends out of the sealed box and is connected to the damper 114.

[0033] The sealing box has a raised part on one side that is close to the outer shell 2 (see...). Figure 6 (at point a).

[0034] The outer casing 2 is secured by a flange 21 that can abut against the sealing box to prevent the main body 11 from leaving the outer casing 2.

[0035] The box is composed of a detachably connected upper cover 116 and a lower cover 117. The upper cover 116 has an opening 1161 that connects the box cavity to the outside and faces the drive shaft 111. The drive shaft 111 passes through the lower cover 117 along the cover hole 1171. The upper cover 116 and the lower cover 117 are engaged by a locking mechanism 115.

[0036] The drive shaft 111 is indirectly connected to the lower cover 117 via a shaft ring 118. A passive shaft 112 with a spacer 119 is integrally provided on the lower cover 117. One end of the spring 113 is fixed to the spacer 119, and the other end is fixed to the shaft ring 118 after being wound around the spacer 119 several times.

[0037] The damper 114 is inserted into the drawer 3 along the socket 31.

[0038] It also includes a transmission mechanism 12, which is located between the outer casing 2 and the drawer 3 and can convert the internal thrust applied by the user onto the drawer 3 into a rotational driving force to drive the drive shaft 111 to rotate.

[0039] The transmission mechanism 12 includes a rack 121 and a gear 122. The rack 121 is installed in the housing 2 and is parallel to the direction in which the drawer 3 enters and exits the housing 2. The gear 122 is sleeved outside the drive shaft 111 and meshes with the rack 121.

[0040] The working process of this utility model:

[0041] During the period when the user pushes drawer 3 into outer casing 2 (e.g. Figure 3As shown, during the process of the drawer 3 being pushed to the left by the user, the gear 122 can rotate along the rack 121 as the drawer 3 moves to the left, thereby driving the drive shaft 111 to rotate. The drive shaft 111 can indirectly wind the spring 113 through the shaft ring 118 to store force in the spring 113. When the drawer 3 is released, the spring 113 can use the stored force to actively push the drawer 3 out of the outer shell 2.

[0042] During the process of drawer 3 moving in and out of outer shell 2, the main body 11 of the device can also use damper 114 to limit the moving speed of drawer 3; wherein, damper 114 can be selected according to the need based on the principle of hydraulic, pneumatic or mechanical friction (such as using liquid to generate resistance through small holes, using gas compression and expansion to generate resistance, or using friction as resistance) to achieve the damping effect.

[0043] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
