[0002] With the improvement of people's living standards, home appliances such as ovens, steamers, and microwave ovens have gradually become one of the essential home appliances for family life. For box-type home appliances, a door body is buckled on the front opening, and a door handle protruding from the surface is usually provided on the front side of the door body. However, the door handle protruding from the door body not only affects the overall appearance of the home appliance, but also, when the user passes in front of the home appliance, the exposed door handle is easy to bump into the user, causing accidental injury to the user.

[0003] In the prior art, it is proposed to set an inwardly recessed groove on the front surface of the door body, and the groove is rotatably covered with a sheet-like cover plate; when the home appliance is in use, the cover plate is flipped toward the outside of the door body so that at least part of the cover plate protrudes from the door body, and a handle is set on the rear surface of the cover plate, and the user puts his hand between the cover plate and the groove, and pulls the door body by pressing the handle with his fingers; when the home appliance is not in use, the front surfaces of the cover plate and the door body are respectively flush, and the handle is hidden in the space between the cover plate and the groove; thereby improving the overall aesthetics of the home appliance, and when the user passes in front of the home appliance, the cover plate flush with the door body will not bump into the user; but there are problems: when in use, the cover plate is flipped outward and protrudes from the door body, and the user may forget to retract the handle after using the appliance, and the user is still prone to bumping into it; in addition, when the user opens the door, the cover plate needs to open the door body by pulling the hinge structure between the cover plate and the door body during the process of pulling the handle, and the hinge structure is prone to damage, resulting in the cover plate being unable to be pulled out or pushed back, affecting user use.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a door body of a household appliance. By arranging a cover plate that flips inward on the mounting groove of the door body, the cover plate never protrudes from the outer surface of the door body, which completely solves the problem that users may bump into the handle of the box-type household appliance. In addition, by arranging the handle inside the mounting groove, the user can put his hand into the mounting groove and pull the handle, so that when opening the door body, the user does not need to pull the cover plate, which solves the problem that the hinge structure between the cover plate and the door body is easily damaged due to pulling.

[0010] Furthermore, a locking structure is provided inside the installation groove, and the locking structure has a locked state connected to the cover plate, and a disconnected and unlocked state; when the cover plate is located in the second position, the locking structure locks or unlocks the cover plate by switching the state.

[0011] Furthermore, a lock tongue protruding outward is provided on the rear surface of the cover plate, and a lock hole is provided on the lock tongue; the locking structure at least includes a lock hook and a driving structure, and the driving structure drives the lock hook to rotate in forward and reverse directions, so that the lock hook penetrates into or escapes from the lock hole.

[0012] Furthermore, the driving structure also includes a slideway, a slideway opening is opened at the top, and a slider that can slide in the vertical direction is arranged in the slideway; a second hinge is arranged at the top of the slider, and the movable end of the second hinge is connected to the front side wall of the lock hook; when the locking structure is in the unlocked state, the slider protrudes from the slideway opening; when the locking structure is in the locked state, the slider is located inside the slideway, and the lock hook is at least partially in contact with the slideway.

[0013] Furthermore, a push-and-pop structure is provided on the driving structure, and the locking structure switches its state through the push-and-pop structure.

[0014] Furthermore, an upwardly protruding abutting protrusion is arranged at the rear side of the top end of the sliding block, and the front side surface of the abutting protrusion is arranged to tilt backward from bottom to top, and the rear end of the locking tongue abuts against the front side surface of the abutting protrusion.

[0015] Furthermore, the lock tongue is vertically arranged to the rear surface of the cover plate, the lock hole is opened on the upper surface of the lock tongue, and the top end of the lock hook is provided with a hook claw portion which is gradually bent backward from bottom to top.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: by arranging the cover plate flipped inward on the mounting groove of the door body, the cover plate never protrudes from the outer surface of the door body, and even if the user forgets to restore the cover plate to the first position, the user will not bump against the handle of the home appliance;

[0017] In addition, by arranging the handle inside the installation groove, when opening the door body, the user can put his hand into the installation groove and pull the handle without pulling the cover plate, thereby ensuring the durability of the hinge structure between the cover plate and the door body and extending the service life;

[0018] Finally, by adding a locking structure inside the installation groove, the cover plate is kept in the second position by the locking structure. Since the cover plate is flipped toward the inside of the installation groove, the user will not bump into the handle while using the home appliance, and the door can be opened and closed conveniently.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] It should be noted in advance that the household appliances described in this application are box-type household appliances such as ovens, microwave ovens and refrigerators.

[0036] like Figure 1-8As shown, in an embodiment of the present invention, a door body 1 of a household appliance is introduced, and a mounting groove 2 with a front opening is provided on the door body 1, and a cover plate 3 is rotatably arranged in the mounting groove 2; a groove wall on one side of the mounting groove 2 is hinged to the cover plate 3, and a handle portion 201 is provided on the side wall on the other side; the cover plate 3 has a first position for covering the groove opening of the mounting groove 2, and a second position for flipping toward the inside of the mounting groove 2.

[0037] Through the above arrangement, by arranging the cover plate 3 flipped inward on the mounting groove 2 of the door body 1, the cover plate 3 never protrudes from the outer surface of the door body 1, and even if the user forgets to restore the cover plate 3 to the first position, the user will not collide with the handle 201 of the home appliance;

[0038] In addition, by arranging the handle portion 201 inside the installation groove 2, when opening the door body 1, the user can put his hand into the installation groove 2 and pull the handle portion 201 without pulling the cover plate 3, thereby ensuring the durability of the hinge structure between the cover plate 3 and the door body 1 and extending the service life.

[0039] In the embodiment of the present invention, the front surfaces of the cover plate 3 and the door body 1 are respectively arranged flush with each other.

[0040] like Figure 3-6 As shown, in an embodiment of the present invention, a first hinge 301 is arranged on the groove wall of the installation groove 2, the movable end of the first hinge 301 is hinged to the rear surface of the cover plate 3, and the hinge axis of the first hinge 301 is arranged at a certain distance from the groove top of the installation groove 2.

[0041] Through the above arrangement, when the cover plate 3 is located at the first position, the movable end of the hinge connected to the cover plate 3 can be flipped backwards, so that the cover plate 3 can be flipped from the first position to the second position through the first hinge 301.

[0042] In the embodiment of the present invention, an inwardly recessed installation groove 2 is provided on the front surface of the door body 1 , and at least one side wall of the installation groove 2 is inclined outward from the groove opening to the groove bottom, and the inclined groove wall constitutes a handle portion 201 .

[0043] Since different household appliances have different requirements for the thickness and material of the door body 1, for example, ovens usually require heat-resistant materials, while refrigerators require cold-resistant materials. Some materials have a high hardness, and it is difficult to open the installation groove 2 on their surface. In addition, the thickness of the door body 1 needs to be greater than the height of the installation groove 2, which makes the production of the door body 1 difficult and the cost high. Therefore, the next embodiment is proposed.

[0044] In another preferred embodiment of the present invention, the mounting groove 2 is buckled on the rear surface of the door body 1, and the groove top of at least one side groove wall of the mounting groove 2 is provided with a baffle 202 extending toward the center of the groove, and the rear surface of the baffle 202 constitutes a handle portion 201; a handle buckle opening 101 connected to the mounting groove 2 is opened on the door body 1.

[0045] Through the above implementation, the material and thickness of the door body 1 can be adjusted according to actual needs through the independently arranged installation groove 2, and the assembly can be completed by simply connecting the installation groove 2 with the door body 1; the production difficulty and cost of the door body 1 are reduced; at the same time, the handle part 201 formed by the baffle 202 of the installation groove 2 is always parallel to the front surface of the door body 1, which is more convenient for the user to hold when in use, and the feel of opening the door is more comfortable; in addition, the baffle 202 can increase the fitting area between the installation groove 2 and the door body 1, reduce the pressure between the installation groove 2 and the door body 1, avoid the deformation of the two due to excessive pressure, and improve the overall service life of the door body 1.

[0046] In an embodiment of the present invention, the handle portion 201 also includes a friction pad with greater friction force laid on the rear surface of the baffle 202; preferably, a friction protrusion with a protruding surface is provided on the rear surface of the friction pad; so as to enhance the friction force of the handle portion 201, and when the user's hands are wet or have water, prevent the hands from slipping between the handle portion 201, making it difficult to open the door body 1.

[0047] In the embodiment of the present invention, a mounting plate 203 extending toward the center of the slot is disposed on the top of the slot wall of the mounting slot 2 opposite to the slot wall where the baffle 202 is disposed, and a first hinge 301 is disposed on the extending end of the mounting plate 203 .

[0048] In an embodiment of the present invention, the hinge axis of the first hinge 301 is located on the side of the end face of the extended end of the mounting groove 2 close to the bottom of the mounting groove 2; preferably, when the cover plate 3 is in the first position, the cover plate 3 abuts against the mounting plate 203; the cover plate 3 is limited by the mounting plate 203 to prevent the cover plate 3 from rotating away from the second position, thereby ensuring that the cover plate 3 is flush with the door body 1.

[0049] In the embodiment of the present invention, the handle portion 201 and the first hinge 301 are respectively located at two opposite positions of the mounting slot 2 .

[0050] In another embodiment of the present invention, the handle portion 201 is hinged to the end wall of the door body 1 that forms the handle opening 101 .

[0051] In an embodiment of the present invention, the bottom side wall of the mounting groove 2 is hinged to the cover plate 3, and the top side wall of the buckle opening 101 is inclined upward from front to back; by setting the inclined side wall, the top of the flipped cover plate 3 can be avoided, making the flipping of the cover plate 3 smoother.

[0052] In the embodiment of the present invention, an elastic structure is provided on the first hinge 301 to keep the cover plate 3 in the first position; preferably, the elastic structure is a torsion spring sleeved on the shaft of the first hinge 301 .

[0053] When in use, the user can push the cover plate 3 to rotate with the back of the hand, and extend the hand into the mounting groove 2 to hold the handle portion 201. At this time, the door body 1 can be pulled outward with the palm of the hand to open the door body 1. When there is no need to open or close the door body 1, the hand can be directly pulled out, and the elastic structure drives the cover plate 3 to reset from the second position to the first position through the elastic force, so that the cover plate 3 is flush with the front surface of the door body 1.

[0054] In an embodiment of the present invention, a locking structure 4 is provided inside the mounting groove 2, and the locking structure 4 has a locked state connected to the cover plate 3, and a disconnected and unlocked state; when the cover plate 3 is in the second position, the locking structure 4 locks or unlocks the cover plate 3 by switching the state.

[0055] Through the above arrangement, by adding a locking structure 4 inside the installation groove 2, the cover plate 3 is maintained in the second position through the locking structure 4, and because the cover plate 3 is flipped toward the inside of the installation groove 2, when the user uses the home appliance, it is ensured that the user will not bump against the handle, and the door body 1 can be opened and closed conveniently.

[0056] In an embodiment of the present invention, an iron sheet is provided on the rear surface of the cover plate 3, and the locking structure 4 includes an electromagnet assembly arranged inside the mounting groove 2, and a control circuit for controlling the power on and off of the electromagnet assembly; by controlling the power supply to the electromagnet assembly, the electromagnet starts or stops generating a magnetic field, attracting the iron sheet on the rear side of the cover plate 3, thereby achieving locking or unlocking of the cover plate 3.

[0057] In another preferred embodiment of the present invention, a lock tongue 310 protruding outward is provided on the rear surface of the cover plate 3, and a lock hole is opened on the lock tongue 310; the locking structure 4 includes at least a lock hook 410 and a driving structure 420, and the driving structure 420 drives the lock hook 410 to rotate in the forward and reverse directions, so that the lock hook 410 is inserted into or disengaged from the lock hole; the drive structure 420 rotates the lock hook 410 to make the lock hook 410 hook on or disengage from the lock hole of the lock tongue 310, thereby realizing the locking of the cover plate 3. Compared with the electromagnetic attraction technical solution in the previous embodiment, this embodiment does not need to set a circuit for powering the electromagnet assembly in the door body 1 while ensuring that the cover plate 3 can be stably locked, thereby reducing the complexity of the door body 1.

[0058] In an embodiment of the present invention, the driving structure 420 also includes a slide 421, a slide opening is opened at the top, and a slider 422 that can slide in the vertical direction is arranged inside the slide 421; a second hinge 412 is arranged at the top of the slider 422, and the movable end of the second hinge 412 is connected to the front side wall of the locking hook 410; when the locking structure 4 is in the unlocked state, the slider 422 protrudes from the slide opening; when the locking structure 4 is in the locked state, the slider 422 is located inside the slide 421, and the locking hook 410 is at least partially in contact with the slide 421.

[0059] Through the above-mentioned arrangement, when the slider 422 partially slides out of the slide 421, the lock hook 410 is in a free state and detached from the lock hole; and when the slider 422 completely slides into the slide 421, the wall surface of the slide 421 contacts the lock hook 410, driving the lock hook 410 to gradually rotate into the lock hole, thereby locking the lock tongue 310 and the cover plate 3; the reciprocating motion of the slider 422 is converted into the rotational motion of the lock hook 410, and through simple actions, the conversion of the locking state of the cover plate 3 by the locking structure 4 is realized.

[0060] like Figure 7 and 8 As shown, in the embodiment of the present invention, a push-pop structure 430 is provided on the driving structure 420, and the locking structure 4 switches its state through the push-pop structure 430; the push-pop structure 430 has the function of being in different states for odd-numbered triggers and later-numbered triggers under the same trigger mode, so that the user can switch the locking state of the cover 3 through the same trigger mode, which is convenient for operation and provides convenience for the user.

[0061] In an embodiment of the present invention, the push-to-pop structure 430 includes a first elastic member 431 arranged at the bottom of the slide 421, and the other end of the first elastic member 431 is connected to the bottom of the slider 422; and an annular locking track 432 is arranged on the surface of one side of the slider 422 to form an inward depression, and the top of the annular locking track 432 is provided with a U-shaped or V-shaped bent track section 433 that is bent obliquely downward and obliquely upward; there is also a locking protrusion 434 protruding from the inner wall of the slide 421 and extending to the inside of the locking track 432, and a limiting slide rail 435 perpendicular to the sliding direction of the slider 422 is provided on the inner wall of the slide 421, and the locking protrusion 434 is slidably arranged in the limiting slide rail 435.

[0062] In the embodiment of the present invention, the bottom of the locking track 432 is located below the bottom of the bent track segment 433 .

[0063] When in use, by pushing the slider 422, the locking track 432 and the locking protrusion 434 are relatively displaced, and the locking protrusion 434 slides in the limiting slide rail 435, so that the protrusion end is always kept in the locking track 432; when the locking structure 4 is in the unlocked state, the locking protrusion 434 is located at the bottom of the locking track 432;

[0064] When the locking structure 4 is switched to the locked state, the slider 422 is pushed to move inside the slideway 421, and the locking protrusion 434 first slides to one end of the bent track section 433. During this process, the lock hook 410 rotates into the lock tongue 310 along with the movement of the slider 422; then the thrust on the slider 422 is canceled, and the first elastic member 431 pushes the slider 422 to move toward the slideway opening, and the locking protrusion 434 slides along the bent track section 433 to the bottom of the bent track section 433 and remains at this position. At this time, the lock hook 410 keeps the hook set on the lock tongue 310, so that the cover plate 3 is locked in the second position;

[0065] When the locking structure 4 switches to the unlocked state, the slider 422 is pushed to move toward the inside of the slide 421, and the locking protrusion 434 moves from the bottom of the bent track to the other end. During this process, the lock hook 410 still remains hung on the lock tongue 310; then the thrust on the slider 422 is cancelled, and the first elastic member 431 pushes the slider 422 to move toward the slide opening, and the locking protrusion 434 slides along the locking track 432 to the bottom of the locking track 432 and remains in this position. During this process, the top of the slider 422 gradually protrudes out of the slide opening, and the lock hook 410 flips over and turns away from the lock tongue 310, thereby unlocking the cover plate 3 locked in the second position.

[0066] Through the above-mentioned arrangement, by the cooperation between the locking rail 432 and the locking protrusion 434, the slider 422 is positioned at different heights to realize the switching between the states of the locking structure 4; the overall structural complexity of the locking structure 4 is relatively low, and during use, it is only necessary to push the slider 422 downward to realize the switching of the states of the locking structure 4, which is easy to operate and has strong stability.

[0067] In an embodiment of the present invention, the annular locking track 432 is composed of three locking track 432 sections, a bent track section 433 and an unlocking track section connected end to end, and the locking track 432 section and the unlocking track section are connected at the bottom position of the locking track 432; the degree to which the end of each track section is recessed in the surface of the slider 422 is smaller than the degree of recessedness of the starting end of the connected track section, so that a step structure is formed at the connection between each track section; the protruding ends of the locking protrusion 434 are respectively provided with abutment structures, and a second elastic member is provided between the abutment structure and the locking protrusion 434, and the abutment structure abuts against the locking track 432.

[0068] Through the above-mentioned arrangement, by arranging a step structure at the connection of the three track segments, the locking protrusion 434 can realize track jump through the step structure when sliding to each connection, so that during use, the locking protrusion 434 can stably move along the preset trajectory route, thereby ensuring the stable operation of the locking structure 4; at the same time, by arranging a second elastic member and an abutment structure, a locking protrusion 434 with a retractable front end is formed, so that the front end of the locking protrusion 434 can always abut against the locking track 432, further ensuring the stable operation of the locking structure 4.

[0069] In the embodiment of the present invention, the locking track 432 of the locking structure 4 is arranged on a side of the slider 422 away from the cover plate 3 .

[0070] In the embodiment of the present invention, the locking protrusion 434 is arranged on the inner wall of the slideway 421 away from the cover plate 3 .

[0071] In the embodiment of the present invention, the limiting slideway 421 is extended horizontally.

[0072] like Figure 1-8 As shown, in the embodiment of the present invention, an upwardly protruding abutting protrusion 423 is provided on the rear side of the top end of the slider 422, and the front side surface of the abutting protrusion 423 is inclined backward from bottom to top, and the rear end of the locking tongue 310 abuts against the front side surface of the abutting protrusion 423; by setting the abutting protrusion 423, during the flipping process of the cover plate 3, the rear end of the locking tongue 310 abuts against the abutting protrusion 423, pushing the abutting protrusion 423 and the slider 422 to move downward to realize the switching of the state of the locking structure 4, which is convenient for users to use.

[0073] During use, the cover plate 3 can be locked in the second position by simply pushing the cover plate 3 to flip it into the mounting groove 2; when the cover plate 3 needs to be switched to the first position, the user only needs to push the cover plate 3 again to flip it toward the inside of the mounting groove 2 to trigger the push-pop structure 430, and at this time, the cover plate 3 can be unlocked from the second position and reset to the first position by simply letting go.

[0074] In the embodiment of the present invention, the lock tongue 310 is vertically arranged to the rear surface of the cover plate 3, the lock hole is opened on the upper surface of the lock tongue 310, and the top end of the lock hook 410 is provided with a hook claw portion 411 which is gradually bent backward from bottom to top; so as to facilitate the lock hook 410 to be hooked on the lock tongue 310; at the same time, the arc surface formed by the gradually bent hook claw portion 411 facilitates the lock hook 410 to rotate and penetrate into the lock hole.

[0075] In the embodiment of the present invention, the outer surface of the slide 421 close to the cover plate 3 is set as a slope inclined from top to bottom toward the cover plate 3. When the cover plate 3 is in the second position, the outer surface of the slide 421 is set in parallel with the rear surface of the cover plate 3; preferably, the outer surface is set in parallel with the rear surface of the cover plate 3 at a certain distance; a space for the cover plate 3 to flip is formed by the inclined surface, and the inclined surface forms an obtuse angle with the top surface of the slide 421. When the cover plate 3 contacts the slide 421, the obtuse corner is not easy to damage the surface of the cover plate 3, thereby preventing the cover plate 3 from deformation; and the spacing distance provides the cover plate 3 with further flipping space to push the slider 422 to trigger the push-pop structure 430, thereby reducing the groove depth of the mounting groove 2, making the arrangement between the components more compact, and reducing the overall thickness of the door body 1.

[0076] In the embodiment of the present invention, the bottom of the door body 1 is hinged to one side edge of the opening of the home appliance, and the door body 1 is turned around the hinge axis to open the opening of the home appliance.

[0077] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
