[0033] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like numerals indicate like elements or elements having the same or similar function throughout the several views. The embodiments described below are exemplary only and are not to be construed as limiting the present application.

[0034] First of all, it needs to be pointed out that the kitchen equipment can be a dishwasher, a steamer, an oven and the like kitchen cleaning equipment embedded in a cabinet or a closet and kitchen cooking equipment, which has a processing space (i.e. a cooking space of an oven, a steamer and the like, a cleaning space of a dishwasher) and needs to be provided with a door body to selectively open or close the processing space to improve the cleaning effect or the cooking effect.

[0035] However, the kitchen device needs to ensure that the processing space is separated from the outside and has good sealing performance based on cooking or cleaning requirements when the door body is in the closed position, so the door body needs to be set larger and has a certain thickness, and the door body with large thickness has large displacement during opening, the lower side edge of the door body is easy to interfere with the skirting line, so that the door body cannot be opened, and after cutting the skirting line, the indoor aesthetic appearance is reduced.

[0036] Based on this, the present application provides a hinge assembly 100 which can adjust the movement track of the door body to avoid interference with the skirting line during opening or closing of the door body, so that the skirting line does not need to be cut, and the indoor aesthetic appearance can be improved.

[0037] The following refers to Figures 1-5 The hinge assembly 100 and the kitchen device according to the embodiments of the present application are described.

[0038] As shown in Figure 1 , Figure 2 and Figure 3 , the hinge assembly 100 according to the first embodiment of the present application comprises a fixed leaf 10 and a movable leaf 20, the movable leaf 20 can be flipped relative to the fixed leaf 10 to switch between the open position and the closed position, corresponding to the door body connected with the movable leaf 20, the box body connected with the fixed leaf 10, to realize the opening and closing of the door body relative to the box body.

[0039] Wherein, the fixed leaf 10 is provided with a first pin shaft 11 and a second pin shaft 12, and the movable leaf 20 is provided with a first sliding groove 21 matched with the first pin shaft 11 and a second sliding groove 22 matched with the second pin shaft 12, so that the movable leaf 20 can switch between the open position and the closed position, and during the opening and closing process, the end point 23 first moves away from the lower edge of the fixed leaf 10, and the end point 23 is located in the same horizontal plane in the open position and the closed position (see Figure 2 and Figure 3 ).

[0040] Specifically, the end point 23 of the lower side edge of the movable leaf 20 corresponds to the lower side edge of the door body, and the lower edge of the fixed leaf 10 remains fixed during the opening and closing process of the hinge assembly 100, can be used as a reference point to fix the relative position of the skirting, can be equivalent to the upper side edge of the skirting, makes the first pin shaft 11 and the first sliding groove 21 slide together, the second pin shaft 12 and the second sliding groove 22 slide together, and the mutual limiting of the first pin shaft 11 and the first sliding groove 21 and the second pin shaft 12 and the second sliding groove 22 can limit the movement track of the movable leaf 20, so that the end point 23 of the movable leaf 20 is in the same horizontal plane in the opening position and the closing position, and the lower side edge of the door body is in the same horizontal plane, and the end point 23 always moves away from the lower edge of the fixed leaf 10 (the lower edge of the door body moves away from the skirting) during the opening process or the closing process.

[0041] It can be understood that the upper side edge of the skirting is in the same horizontal plane, and the lower side edge of the door body can be in another horizontal plane above the upper side edge of the skirting in the closing position. The end point 23 in the same horizontal plane in the opening position and the closing position can ensure that the lower side edge of the door body does not interfere with the skirting in the opening position and the closing position, and can improve the convenience of opening and closing the door body. During the opening and closing process, the lower side edge of the door body always moves away from the upper side edge of the skirting first to avoid interference between the door body and the skirting during the opening and closing process, so that the skirting does not need to be cut, and the indoor aesthetics can be improved.

[0042] It should be noted that during the actual opening of the door body, the movement track of the end point 23 can be upward first and then downward to avoid interference during the opening process or the closing process, and the end point 23 is above the skirting in the closing position and the opening position. The movement track of the end point 23 can also be outward translation to move away from the skirting, and upward movement to be above the skirting while moving to the opening position. The above can be directly above or laterally above to avoid interference.

[0043] That is, during the opening or closing process, the door body moves relative to the skirting, that is, the end point 23 moves away from the lower edge of the fixed leaf 10 to avoid interference with the skirting. The optional movement form is various, and the present application does not specifically limit it. The movement to avoid interference between the door body and the skirting should fall within the scope of the present application.

[0044] In addition, the movement of the end point 23 away from the lower edge of the fixed leaf 10 can avoid interference between the skirting and the door body, and during the entire movement process, the end point 23 is first moved away from the lower edge of the fixed leaf 10, and after the interference is effectively avoided, the end point 23 is located on the same horizontal plane at the opening position and the closing position. On the one hand, the interference between the door body provided on the movable leaf 20 and the skirting can be avoided, and the skirting does not need to be cut, thereby improving the indoor aesthetics; on the other hand, the movement track of the door body is more reasonable, and the space occupation at the opening position is smaller, so that the space requirement of the kitchen equipment can be reduced, and the arrangement convenience of the kitchen equipment can be improved.

[0045] It should be noted that the hinge assembly 100 of the embodiment of the present application can also be matched by the first pin shaft 11 and the first sliding groove 21, and matched by the second pin shaft 12 and the second sliding groove 22, so that the distance between the lower edge of the door body and the skirting is zero. At the closing position, the thickness side of the door body in the thickness direction defines the lower edge, at the opening position, the shielding side of the door body for shielding the processing space defines the lower edge, and during the switching process between the opening position and the closing position, the lower edge of the door body changes between the thickness side and the shielding side (specifically, during the opening process, the lower edge of the door body is gradually changed from the thickness side to the shielding side to be defined, and during the closing process, the lower edge of the door body is gradually changed from the shielding side to the thickness side to be defined). The lower edge is a dynamic position. In the prior art, when the door body edge line (the intersection line of the thickness side and the shielding side) corresponding to the end point 23 forms the lower edge, the distance between the door body and the skirting is the closest, and interference is prone to occur. The relative movement relationship between the end point 23 and the lower edge of the fixed leaf 10 is limited in the present application to ensure that the door body edge line moves away from the skirting.

[0046] According to the hinge assembly 100 of the embodiment of the present application, the first pin shaft 11 and the first sliding groove 21 are matched, and the second pin shaft 12 and the second sliding groove 22 are matched, so that the end point 23 is first moved away from the lower edge of the fixed leaf 10 during the opening and closing process, and the end point 23 is located on the same horizontal plane at the opening position and the closing position. On the one hand, interference between the door body provided on the movable leaf 20 and the skirting can be avoided, and the skirting does not need to be cut, thereby improving the indoor aesthetics; on the other hand, the movement track of the door body is more reasonable, and the space occupation at the opening position is smaller, so that the space requirement of the kitchen equipment can be reduced, and the arrangement convenience of the kitchen equipment can be improved.

[0047] In addition, the movement stability of the double-pin-shaft sliding-groove matching structure is higher, the shaking of the door body during the opening and closing process can be reduced, the opening and closing convenience can be improved, and the opening and closing noise generated during the opening and closing process can be reduced, thereby improving the use experience.

[0048] As Figure 2 and Figure 4As shown, according to some embodiments of the present application, the second pin shaft 12 is arranged in front of the first pin shaft 11, and the first pin shaft 11 is arranged above the second pin shaft 12.

[0049] Specifically, the second pin shaft 12 is arranged in front of the first pin shaft 11, and the first pin shaft 11 is arranged with a height difference from the second pin shaft 12, so that in the process of opening the door body, the first pin shaft 11 pulls the sliding leaf to move upward as a whole in the first sliding groove 21, and rotates around the second pin shaft 12 in the second sliding groove 22, so as to drive the end point 23 to move away from the lower edge of the fixed leaf 10 first, so as to achieve the technical purpose of avoiding interference.

[0050] Next, the opening process of the movable leaf 20 of the present application will be described in detail. Figure 5 , the opening process of the movable leaf 20 of the present application will be described in detail.

[0051] Among them, the first sliding groove 21 has first, third and fifth groove sections 21a, 21b and 21c connected in sequence, the second sliding groove 22 has second and fourth groove sections 22a and 22b connected in sequence, and the first groove section 21a and the second groove section 22a are respectively the starting points of the travel of the first sliding groove 21 and the second sliding groove 22, and the fifth groove section 21c and the fourth groove section 22b are respectively the ending points of the travel of the second sliding groove 22 and the first sliding groove 21.

[0052] Further, the opening process of the sliding leaf can be divided into three stages, which are the first stage of cooperation between the first groove section 21a and the first pin shaft 11, the second groove section 22a and the second pin shaft 12; the second stage of cooperation between the third groove section 21b and the first pin shaft 11, the fourth groove section 22b and the second pin shaft 12; the third stage of cooperation between the fifth groove section 21c and the first pin shaft 11, the fourth groove section 22b and the second pin shaft 12.

[0053] As shown in some embodiments, Figure 5 As shown in some embodiments, the first sliding groove 21 includes a first groove section 21a, and the second sliding groove 22 includes a second groove section 22a, the starting point of the travel of the first sliding groove 21 is located at one end of the first groove section 21a, the starting point of the travel of the second sliding groove 22 is located at one end of the second groove section 22a, and the first groove section 21a and the second groove section 22a are used to rotate and move upward during the opening process.

[0054] That is, in the first stage, the first groove section 21a cooperates with the first pin shaft 11, and the second groove section 22a cooperates with the second pin shaft 12, so as to pull the end point 23 to rotate and move upward relative to the lower edge of the fixed leaf 10, realize the preliminary opening of the door body, and avoid interference between the door body and the skirting line during the preliminary opening process.

[0055] As shown in some embodiments, Figure 5As shown, further, in the closed position, the first slot section 21a and the second slot section 22a are configured as concave arc-shaped slots, and the arc length of the second slot section 22a is less than the arc length of the first slot section 21a, and the equivalent circle radius of the first slot section 21a is greater than the equivalent circle radius of the second slot section 22a.

[0056] Thus, in the opening process of the door body, the first pin shaft 11 acts on the first slot section 21a, and the second pin shaft 12 acts on the second slot section 22a, and a torque for pulling the movable leaf 20 upward is generated, thereby driving the end point 23 to move upward, that is, to realize the above-mentioned movement of first driving the end point 23 away from the lower side edge of the fixed leaf 10.

[0057] As shown, Figure 5 in some embodiments, the first slot section 21a is in communication with the third slot section 21b, the second slot section 22a is in communication with the fourth slot section 22b, and the third slot section 21b and the fourth slot section 22b are used to move the end point 23 downward in the opening process.

[0058] That is, in the second stage, the third slot section 21b cooperates with the first pin shaft 11, the fourth slot section 22b cooperates with the second pin shaft 12, and the end point 23 is pulled towards the lower side edge of the fixed leaf 10, that is, to realize the above-mentioned movement limitation of the end point 23 in the closed position and the opening position being in the same horizontal plane.

[0059] It can be understood that moving the end point 23 away from the lower side edge of the fixed leaf 10 first, and then moving it towards the lower side edge of the fixed leaf 10, can not only avoid the reflection of the door body and the skirting line, but also make the stroke of moving away from the lower side edge of the fixed leaf 10 more reasonable in the opening process of the door body, and can reduce the space occupation in the opening position of the door body.

[0060] As shown, Figure 5 further, in the closed position, the third slot section 21b and the fourth slot section 22b are both forwardly inclined and downwardly extended, and the length of the third slot section 21b is greater than the length of the fourth slot section 22b.

[0061] Thus, the first pin shaft 11 can be pulled by the third slot section 21b with a greater length to generate a torque for pulling the movable leaf 20 downward to drive the end point 23 to move downward.

[0062] It should be noted that the third slot section 21b and the fourth slot section 22b can be configured as straight slot sections or arc-shaped slot sections.

[0063] As shown, Figure 2 and Figure 5As shown, the first sliding groove 21 further comprises a fifth groove segment 21c in communication with the third groove segment 21b, the end of stroke of the first sliding groove 21 is located at the fifth groove segment 21c, the end of stroke of the second sliding groove 22 is located at the fourth sliding groove, and the fifth groove segment 21c is used to drive the end point 23 to rotate during the opening process.

[0064] That is, in the third stage, the fifth groove segment 21c cooperates with the first pin shaft 11, the fourth groove segment 22b cooperates with the second pin shaft 12, and the door body finally moves to the open position in the third stage, and before finally reaching the open position, the second pin shaft 12 moves to the end of stroke of the second sliding groove 22 first, and the first pin shaft 11 cooperates with the fifth groove segment 21c to make the door body rotate around the axis of the second pin shaft 12 to the open position, that is, the first stage and the second stage are used to adjust the relative position of the end point 23 and the lower edge of the fixed leaf 10 to avoid interference between the skirting line and the door body, and the second stage is further rotated to achieve complete opening of the door body.

[0065] Based on this, the fifth groove segment 21c is configured as an arc-shaped groove.

[0066] As shown in Figure 1 , Figure 2 and Figure 4 According to some embodiments of the present application, a limiting plate 30 is arranged on one of the movable leaf 20 and the fixed leaf 10, and a limiting arm 40 cooperating with the limiting plate 30 is arranged on the other.

[0067] Specifically, the limiting plate 30 can be arranged on the movable leaf 20, and the limiting arm 40 is arranged on the fixed leaf 10, or the limiting plate 30 is arranged on the fixed leaf 10, and the limiting arm 40 is arranged on the movable leaf 20, the pushing and abutting cooperation of the limiting plate 30 and the limiting arm 40 limits the opening angle of the movable leaf 20, and the door body can realize hovering at this position after moving to the open position, avoiding over-opening of the door body.

[0068] Correspondingly, a buffer structure can be arranged on the limiting arm 40 or the limiting plate 30, which can provide a buffer for the door body, avoid a large opening noise caused by excessive opening force of the user, and improve the opening stability of the door body. Some door bodies can be provided with transparent structures such as glass and acrylic plates, so as to form a visual kitchen device, which can also avoid the transparent structure from being broken, prolonging the service life of the door body.
