Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a drawer-type clothing processing device. Background Art

[0002] There are two major technical challenges in the operation of current drawer-type laundry treatment equipment: First, when loading clothes and shoes for washing, the uneven load distribution in the impeller drum often causes the impeller's rotation axis to deviate, thus causing significant operating vibration. Figure 1 As shown, the drawer-type design requires that the door lock rod 1 must maintain a certain clearance L with the limit device 2 of the drawer-type inner container after closing, so as to prevent the door lock rod from being unable to be smoothly inserted and locked due to too tight contact during the closing process, or being blocked from extending and causing the door to fail to close. However, in the actual production process, due to the accumulation effect of the manufacturing tolerance of the parts, the gap between the door lock rod and the limit device may gradually increase.

[0003] Once the eccentricity problem during the washing process worsens, and the gap between the door lock rod and the limit device is too large, the front door panel is likely to swing back and forth significantly when the equipment is running, which will not only cause additional noise problems, but also seriously affect the user experience. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0040] Reference Figure 2 and Figure 3 , is an embodiment of the drawer-type clothes processing device of the utility model. The drawer-type clothes processing device can be a drawer-type washing machine, a drawer-type shoe washing machine, etc.

[0041] The drawer type clothes treating apparatus includes an outer case 100 and an inner case 200 .

[0042] The outer box 100 is a device shell.

[0043] The inner box 200 is arranged in the outer box 100 in a retractable manner. The inner box 200 can be retracted by a pulley or a slide rail. A door panel 300 is arranged at the front side of the inner box 200. The washing tub is arranged on the inner box 200, and the pulsator is located at the bottom of the washing tub. When washing, the pulsator rotates to wash clothes or shoes.

[0044] The door lock assembly 400 is disposed on the inner box 200 or the door panel 300. In this embodiment, the door lock assembly is disposed on the door panel 300.

[0045] Specifically, the door lock assembly 400 includes a lock body 410 and a lock tongue 420 that can extend out of the lock body 410 .

[0046] The outer box body 100 is also provided with a gap adapting structure 500 .

[0047] Specifically, the gap adaptation structure 500 includes a fixing member 510 , a sliding member 520 and an elastic member 530 .

[0048] The fixing member 510 is fixedly connected to the outer box body 100 .

[0049] The sliding member 520 is slidably disposed on the fixing member 510 in a direction perpendicular to the pulling direction. The sliding member 520 is used to cooperate with the locking tongue 420 to limit the degree of freedom of the inner box body 200 in the pulling direction.

[0050] The sliding member 520 is provided with a plurality of positioning steps 521 .

[0051] When the inner box body 200 is pushed inward into place, the locking tongue 420 extends out of the lock body 410. The locking tongue 420 cooperates with different positioning steps 521 to compensate for part or all of the gap between the locking tongue 420 and the sliding member 520 along the pulling direction, that is, there is no gap (or a very small gap) between the locking tongue 420 and the step surface of the positioning step 521, thereby accurately limiting the freedom of the inner box body 200 in the pulling direction.

[0052] The elastic member 530 is connected to the sliding member 520, and is used for the adaptive sliding of the sliding member 520 when locked and the reset of the sliding member 520 after unlocking. When locked, the elastic member 530 can ensure that the sliding member 520 is always pushed forward by the elastic member 530 to press the extended end of the lock tongue 420. The maximum pressure of the extended lock tongue 420 is greater than the maximum elastic force of the elastic member 530, so as to ensure that the lock tongue 420 can overcome the resistance of the elastic member 530 and push the sliding member 520 to slide.

[0053] The working process of the above-mentioned drawer-type clothes processing device is as follows: when the inner box 200 is closed, Figure 2 As shown, the lock tongue 420 extends, and the end of the lock tongue 420 contacts the sliding member 520. The lock tongue 420 pushes the sliding member 520 and inserts into the step surface of the positioning step 521 with a similar height. The lock tongue 420 fits with the corresponding step surface, and the inner box 200 is locked in the degree of freedom in the pulling direction. At this time, the door lock is locked and the device operates normally. When the device is eccentric, the front door will not move in the pulling direction due to the limited degree of freedom of the inner box 200.

[0054] The above-mentioned drawer-type clothing processing device has a multi-step step structure of the sliding member 520. When facing the problem of different gaps, the gaps can be filled by effectively cooperating between the locking tongue 420 and the corresponding positioning steps 521, thereby accurately limiting the freedom of the inner box body 200 in the pulling direction and preventing the inner box body 200 from producing unnecessary shaking. In addition, the locking tongue 420 only needs to overcome the resistance of the elastic component to extend, and the extension of the locking tongue 420 will not be blocked, thereby ensuring that the door body can be closed smoothly.

[0055] In this embodiment, a step portion 421 is provided on the extended end of the lock tongue 420, and the step portion 421 is used to engage with the multi-stage positioning step 521. The two vertical step surfaces on the step portion 421 of the lock tongue 420 can fit with the two vertical step surfaces of the positioning step 521 on the sliding member 520, thereby improving the fit between the lock tongue 420 and the sliding member 520.

[0056] In this embodiment, each step of the multi-level positioning steps 521 has an equal width, so as to be matched with the step portion 421 at the end of the locking tongue 420 .

[0057] The height of each step of the multi-step positioning step 521 is also equal.

[0058] The height of each step is in the range of 1-5 mm. The height of each step should not be too large to avoid a gap between the locking tongue 420 and the corresponding positioning step 521 in the push-pull direction. Theoretically, the height of each positioning step 521 is as small as possible to minimize the gap between the locking tongue 420 and the positioning step 521.

[0059] The total height of the multi-level positioning step 521 needs to ensure that its highest point and lowest point can cover the maximum value and the minimum value of the gap.

[0060] In this embodiment, the elastic member 530 is a spring, one end of the spring is connected to the sliding member 520 , and the other end of the spring is connected to the fixing member 510 .

[0061] A spring installation groove is provided on one side of the sliding member 520 away from the locking tongue 420 , and the end of the spring is installed in the spring installation groove.

[0062] In other embodiments, the elastic member 530 may also be an elastic body or a spring sheet with relatively high elasticity such as rubber.

[0063] In this embodiment, the fixing member 510 is an L-shaped fixing block. A sliding limiter may be provided on the fixing block for sliding limiter, such as a sliding groove, and the sliding member 520 is slidably disposed in the sliding groove.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
