When the door body 2 is in a closed state, i.e. the door body 2 covers the storage space opening, the door front wall 21 is arranged on the side of the door body 2 facing away from the box front wall 11. In this embodiment, the door front wall 21 is entirely planar, and the door front wall 21 is substantially parallel to the box front wall 11 when the door body 2 is in the closed state.

The tank 1 is arranged beside the external environment member, and after the tank 1 is put in place, the tank side wall 12 faces the first side of the external environment member, i.e. the tank side wall 12 is positioned opposite to the first side of the external environment member, and the tank side wall 12 is substantially parallel to the first side of the external environment member.

In the closed state of the door body 2, the door side wall 22 also faces the first side of the external environment member, the door side wall 22 being located opposite to the first side, the door side wall 22 being entirely planar in this embodiment, and the door side wall 22 being substantially parallel to the first side of the external environment member.

In this embodiment, the door front wall 21 and the door side wall 22 are both substantially planar, and when the door body 2 is in the closed state, the door front wall 21 is parallel to the box front wall 11, and the plane of the door side wall 22 is parallel to the plane of the box side wall 12. Of course, in other embodiments, the door front wall 21 and the door side wall 22 may be curved or arcuate.

In this embodiment, as shown in fig. 1-5, the hinge assembly 3 includes a movable shaft 31 and a slot 32, where the movable shaft 31 includes a shaft body 311 movable in the slot 32, and the shaft body 311 and the slot 32 are relatively movable during opening of the door 2.

In a specific embodiment, the groove body 32 comprises a first track groove 321 and a second track groove 322, and the shaft body 311 sequentially moves in the first track groove 321 and the second track groove 322;

The groove body 32 further has an engagement groove 323 between the first track groove 321 and the second track groove 322, the engagement groove 323 serving as an engagement portion between the first track groove 321 and the second track groove 322, and the engagement groove 323 can also be regarded as an overlapping position of the extension of part of the first track groove 321 and the extension of part of the second track groove 322. The shaft body 311 moves from the engagement groove 323 to the second track groove 322 from the first track groove 321.

The shaft body 311 is in sliding fit with the first track groove 321, and two opposite sides of the engagement groove 323 respectively form a protruding part 3231 protruding towards the engagement groove 323 and a recessed part 3232 concavely arranged towards the direction away from the engagement groove 323;

The shaft body 311 has a flat cross section as a whole and has a longitudinal direction and a width direction, the shaft body 311 is provided with a relief groove 3111 provided to be opened in the width direction of the shaft body 311, and the relief groove 3111 is positioned opposite to the protruding portion 3231 when the shaft body 311 slides to the engagement groove 323.

In this embodiment, the movement of the door body 2 can be realized by sliding the shaft body 311 along the first track groove 321 during the opening process of the door body 2, and the shaft body 311 can be prevented from rotating in the circumferential direction in the first track groove 321 when sliding along the first track groove 321 due to the flat shape of the shaft body 311 as a whole. When the shaft body 311 rotates circumferentially in the first track groove 321, the door body 2 rotates synchronously, and the door outer edge 23 is interfered by external environment parts due to the premature rotation of the door body 2. The flat arrangement of the shaft body 311 in this embodiment can enable the door body 2 to slide along the first track groove 321 instead of rotating at the initial stage of opening, so as to effectively avoid interference between the door body 2 and the external environment at the initial stage of opening.

The arrangement of the flat shaft body 311 can effectively prevent the shaft body 311 from rotating in the circumferential direction in the first track groove 321, but when the entire groove body 32 is provided with a plurality of track grooves, the sliding of the flat shaft body 311 in the groove body is limited due to the need of steering in different track groove combining positions due to the sliding direction.

Specifically, in this embodiment, the groove body 32 includes a first track groove 321 and a second track groove 322, the first track groove 321 and the second track groove 322 are connected by a joint groove 323, the first track groove 321 and the second track groove 322 are integrally extended in different directions, and the extending directions of the first track groove 321 and the second track groove 322 are integrally intersected, so that a protrusion 3231 protruding relatively toward the joint groove 323 and a recess 3232 recessed relatively away from the joint groove 323 are formed on opposite sides of the joint groove 323. That is, the groove body is turned at the position of the engagement groove 323, and the shaft body 311, which is flat as a whole, is easily interfered when turning from the extending direction of the first track groove 321 to the extending direction of the second track groove 322 due to the protrusion portion 3231, resulting in uneven rotation.

In this embodiment, the shaft body 311 is provided with the escape groove 3111, and the escape groove 3111 is opened in the width direction of the shaft body, and the escape groove 3111 is positioned so as to face the protruding portion 3231 when the shaft body 311 slides to the engagement groove 323. Therefore, the flat shaft body 311 can better realize steering in the groove body, and the door body 2 can be smoother in the opening process on the premise of not increasing the width of the groove body 32.

In this embodiment, the relief groove 3111 is adapted to the protruding portion 3231. The opening size of the escape groove 3111 is not smaller than the size of the protruding portion 3231, and the above arrangement enables the protruding portion 3231 to be more favorably rotated in the escape groove 3111.

In a specific embodiment, as shown in fig. 1 to 4, the first track groove 321 is integrally elongated, and the extending shape of the first track groove 321 may be a straight line or a curved line, and in this embodiment, in order to better implement the movement of the position of the door body 2, the first track groove 321 is integrally curved and extends.

The second track groove 322 is integrally arranged in a linear extending manner, and an included angle between a tangential direction of the end position of the first track groove 321 and the extending direction of the second track groove 322 is not smaller than 90 degrees.

In the prior art, in order to realize that the opening angle of the door body is generally smaller in the included angle of the extending directions of the adjacent track grooves when the multi-section track grooves are arranged, the difficulty of sliding the shaft body 311 in different track grooves is increased by the smaller included angle, and particularly, the shaft body extending in a certain direction in a flat shape is improved. In this embodiment, the axle body 311 can generate more relative rotation when sliding along the slot body through the arrangement of the avoiding slot 3111, so that more relative rotation of the axle body 311 can be realized when the included angle of the extending direction between the first track slot 321 and the second track slot 322 is larger, the door body 2 can be opened by larger rotation without the design of smaller included angle of the extending direction between the first track slot 321 and the second track slot 322, and sliding of the axle body 311 is smoother.

The shape of the first track groove 321 is arc, and the curved section of the first track groove 321 is a circular section, so that the arrangement of the structure can enable the shaft body 311 to slide in the first track groove 321 more smoothly.

As shown in fig. 3-4, the outer wall of the shaft body 311 further has a pair of arc surfaces 3112, where the arc surfaces 3112 are disposed opposite to each other along the length direction, the arc surfaces 3112 protrude in opposite directions, and the protruding direction of the arc surfaces 3112 is perpendicular to the opening direction of the avoidance groove 3111.

The shaft body 311 is provided with a pair of arc-shaped surfaces 3112 arranged opposite to each other in the length direction, so that the shaft body 311 can slide more smoothly when sliding in the groove body 32.

As shown in fig. 4, a side of the shaft body 311 away from the avoidance groove 3111 is provided with a secondary avoidance groove 3113 disposed opposite to the avoidance groove 3111, and the secondary avoidance groove 3113 and the avoidance groove 3111 are symmetrically disposed along a width direction of the shaft body 311;

The arc surface 3112 is connected between the avoidance groove 3111 and the auxiliary avoidance groove 3113, a first rotation limiting portion 3114 is formed at a combined position of the arc surface 3112 and the avoidance groove 3111, a second rotation limiting portion 3115 is formed at a combined position of the arc surface 3112 and the auxiliary avoidance groove 3113, the first rotation limiting portion 3114 and the second rotation limiting portion 3115 are respectively used for abutting against an inner wall of the groove body 32 so that when the shaft body 311 slides along the groove body 311, the book searching shaft body 311 rotates circumferentially in the groove body 32.

Through set up rotatory spacing portion on the outer wall of axis body 311 in order to realize offing with first track groove 321 inner wall, adopted simple structure to realize axis body 311 in first track groove 321 circumference pivoted spacing, the structure is simpler, and the operation is more convenient.

The first rotation limiting portion 3114 and the second rotation limiting portion 3115 are arranged along the width direction of the shaft body, and the first rotation limiting portion 3114 and the second rotation limiting portion 3115 are symmetrically disposed at two sides of the shaft body 311.

Because the shaft body 311 is formed with a pair of arcuate surfaces 3112 disposed opposite to each other, the corresponding first rotation limiting portions 3114 and second rotation limiting portions 3115 are also provided with a pair, the pair of first rotation limiting portions 3114 are arranged along the length direction of the shaft body 311, and the pair of second rotation limiting portions 3115 are arranged along the length direction of the shaft body 311.

The shaft body 311 realizes the limitation of the rotation of the shaft body 311 along the circumferential direction through four rotation limiting parts when sliding along the first track groove 321, and the shaft body 311 contacts with one side inner wall of the first track groove 321 through two rotation limiting parts, and one surface limitation can be realized at two points, so that compared with the contact of the shaft body 311 with the whole surface of the inner wall of the first track groove 321, the rotation limitation realized by adopting two rotation limiting parts in the embodiment can enable the shaft body 311 to move more smoothly in the first track groove 321.

In a specific embodiment, the movable shaft 31 may be provided on the door body 2 or on the case body 1. When the movable shaft 31 is disposed on the case 1, the groove 32 is correspondingly disposed on the door 2, as shown in fig. 1 to 8, and when the movable shaft 31 is disposed on the door 2, the groove 32 is correspondingly disposed on the case 1, as shown in fig. 9 to 16.

As shown in fig. 1 to 8, when the movable shaft 31 is provided on the case 1, in order to facilitate the provision of the movable shaft 31, the hinge assembly 3 further has a hinge plate 33 provided on the case 1, the movable shaft 31 has a mounting portion 312 fixed to the hinge plate 33, and the shaft body 311 and the mounting portion 312 are arranged in the axial direction of the shaft body 311.

The cell body 32 is directly set up on the door body 2, and the bottom or the top of the door body 2 directly forms up or the groove that opening set up down, and the axis body 311 location is in the groove, and the installation of the door body 2 on box 1 of realization that like this structure is fixed be convenient for the loading or the dismantlement of the door body 2 of more convenient.

As shown in fig. 1, when the door 2 is in the closed state, the shaft 311 is positioned at the start end of the first track groove 321, and the start end of the first track groove 321 is disposed relatively close to the door front wall 21. The end of the first trajectory groove 321 is located closer to the door side wall 22 and the box front wall 12 than the beginning.

As shown in fig. 1, in the closed state of the door body 2, since the start end of the first trajectory groove 321 is located relatively close to the door front wall 21 and relatively far from the door side wall 22, and the start end of the first trajectory groove 321 is located further from the tank front wall 11 and the tank side wall 12 than the end of the first trajectory groove 321. The door body 2 slides from the beginning to the end along the first trajectory groove 321 with respect to the shaft body 311 during the opening. When the door 2 is in the closed state, the first trajectory groove 321 is provided so as to extend in a direction gradually approaching the tank front wall 11 and the tank side wall 12, and the extending direction of the first trajectory groove 321 is the entire direction moving from the start end to the end of the first trajectory groove 321.

The first track groove 321 is provided so that the door body 2 as a whole has a movement tendency to move relatively in a direction away from the side wall 12 of the box and away from the front wall 11 of the box during the opening of the door body 2. Taking the door body 2 as a reference, the shaft body 313 has a motion component that gradually moves relatively toward away from the door front wall 21 and toward the door side wall 22.

In the initial stage of opening the process, the door outer edge 23 and the door inner edge 24 are located at positions far away from the shaft body 311, so that the door outer edge 23 is prevented from being influenced by interference of external environment pieces and the door inner edge 24 is prevented from being influenced by interference of the box body 1, the first track groove 321 is integrally extended towards the position where the door inner edge 24 is located, the door body 2 is obliquely pulled out in the oblique direction in the structure setting in the opening process, and after the door body 2 moves to a position convenient to rotate and open, further subsequent rotation is achieved.

As shown in fig. 2, the first track groove 321 is integrally provided with a curved extending portion, and the first track groove 321 includes a first groove section and a second groove section that are sequentially provided along the extending direction of the first track groove 321, and the second groove section is located between the second track groove 322 and the first groove section.

In the opening process of the door body 2, along with the increase of the opening angle of the door body 2, the shaft body 311 slides along the first groove section and the second groove section in sequence. The first groove section and the second groove section are not clearly defined, and only the sliding process of the shaft body 311 in the first track groove 321 is indicated.

The movement of the shaft 311 in the direction relatively far from the door front wall 21 is greater than the movement of the shaft 311 in the direction relatively close to the door side wall 22, and the movement of the door 2 in the direction relatively far from the door front wall 21 is greater than the movement of the door 2 in the direction relatively far from the box side wall 12 when the first groove section slides.

When the first slot section is moved, the door body 2 is more prone to move in a direction away from the case 1 than to move away from the external environmental member. I.e. the door body 2 is more prone to move forward than to move inward. Here, the front means that the door body 2 moves away from the case 1, and inward movement means that the door body 2 moves away from the external environment.

The movement of the shaft 311 relatively far from the door front wall 21 is smaller than the movement of the shaft 311 relatively close to the door side wall 22, and the movement of the door 2 toward the box front wall 11 is smaller than the movement of the door 2 toward the box side wall 12 while the second groove section slides. I.e. when the second channel section is moved, the door body 2 is more prone to move away from the external environmental element than to move away from the box body 1. I.e. the door body 2 is more prone to move inwards than to move forwards.

The above structure is actually arranged such that when the door body 2 is opened to a first angle, the shaft body 311 slides along the first slot section, the door body 2 moves forward a distance greater than the inward moving distance, and when the door body 2 is opened from the first angle to a second angle, the shaft body 311 slides along the second slot section, and the inward moving distance of the door body 2 is greater than the forward moving distance, wherein the second angle is greater than the first angle.

The arrangement of the structure enables the whole first track groove 321 to be in arc extending arrangement, and the arc formed by the first track groove 321 is arched towards the direction deviating from the door outer edge 23, and the whole first track groove 321 is in extending arrangement towards the direction gradually approaching the door side wall 22 and gradually separating from the door front wall 21.

While the relative movement of the shaft body 311 throughout the first trajectory groove 321 is relatively gradual extending away from the door front wall 21 and toward the door side wall 22, the first groove section is more prone to extend away from the door front wall 21 and the second groove section is more prone to extend beyond the door side wall 22.

Since the door inner edge 24 is farther from the shaft body 311 in the initial stage of the door opening, more consideration is required to be given to the interference of the door inner edge 24 with the case 1 in the initial stage, and thus more movement of the door body 2 in a direction away from the case 1, that is, movement of the shaft body in a direction away from the door front wall 21 is required.

After opening to a certain angle, more consideration is required for interference of external environmental members, so that the door body 2 is moved more inward, that is, the shaft body 311 is moved more relatively toward the door sidewall 22. The arrangement of the structure can carry out finer control on the opening process of the door body 2 according to the actual requirement in the opening process of the door body 2, and can better avoid the interference of the door body 2 in the opening process.

In the initial stage of opening the door body 2, the door outer edge 23 is gradually moved toward the plane near the side wall 12 of the box, and then, with further opening of the door body 2, the door outer edge 23 is gradually moved toward the plane far from the side wall 12 of the box.

When the door body 2 is closed, the second trajectory groove 322 is provided to extend in a direction approaching the door front wall 21 and the door side wall 22 as a whole, that is, the second trajectory groove 322 extends in a direction gradually approaching the door front wall 21 and the door side wall 22 as a whole from the start end to the end of the second trajectory groove 322. When the door body 2 is closed, the second track groove 322 is integrally extended in a direction approaching the door outer edge 23.

As shown in fig. 9 to 16, when the movable shaft 31 is disposed on the door body 2, the corresponding slot body 32 is disposed on the case body 1, and in order to facilitate the disposition of the slot body 32 on the case body 1, the hinge assembly further has a hinge plate 33 disposed on the case body 1, the slot body 32 is disposed on the hinge plate 33, the movable shaft 31 has a mounting portion 312 fixedly connected to the door body 2, and the shaft body 311 and the mounting portion 312 are arranged in the axial direction of the shaft body 311.

As shown in fig. 12, the movable shaft 31 is provided with an upper limiting plate 313 and a lower limiting plate 314, the shaft body 311 is disposed between the upper limiting plate 313 and the lower limiting plate 314, the upper limiting plate 313 is used for abutting against the upper side of the hinge plate 33, and the lower limiting plate 314 is used for abutting against the lower side of the hinge plate 33.

The movable shaft 31 is mounted and positioned in the axial direction on the hinge plate 33 by the arrangement of the upper and lower limiting plates 313 and 314 in the axial direction.

The groove body 32 is directly provided on the hinge plate 33 and penetrates the hinge plate 33 in the vertical direction, the bottom or top of the door body 2 is directly formed with a groove provided upward or downward opening, and the shaft body 311 is positioned in the groove.

As shown in fig. 10, in the closed state of the door body 2, the shaft body 311 is positioned at the start end of the first trajectory groove 321, and the start end of the first trajectory groove 321 is positioned closer to the tank side wall 12 and the tank front wall 11 than the end of the first trajectory groove 321.

The door body 2 slides relatively along the first track groove 321 during opening, so that the door body 2 as a whole moves relatively in a direction away from the side wall 12 of the box and away from the front wall 11 of the box, that is, the door body 2 moves inward and moves toward the front side.

As shown in fig. 9 to 10, in the closed state of the door 2, the shaft body 31 is relatively located closer to the tank side wall 12 and to the tank front wall 11, while the shaft body 31 is also located closer to the door side wall 22 and away from the door front wall 21 in the initial stage of closing of the door 2.

In order to avoid the influence of the interference of the external environmental member on the door outer edge 23 and the influence of the interference of the case 1 on the door inner edge 24, the first trajectory groove 321 is provided to extend in a direction away from the case side wall 12 and away from the case front wall 11 as a whole.

As shown in fig. 14, the first track groove 321 is integrally provided with a curved line, and the first track groove 321 includes a first groove section and a second groove section that are sequentially provided along the extending direction of the first track groove 321, and the second groove section is located between the second track groove 322 and the first groove section. In the opening process of the door body 2, along with the increase of the opening angle of the door body 2, the shaft body 311 slides along the first groove section and the second groove section in sequence. The first groove section and the second groove section are not clearly defined, and only the sliding process of the shaft body 311 in the first track groove 321 is indicated.

The movement of the shaft body 311 relatively far from the tank side wall 12 is greater than the movement of the shaft body 311 relatively far from the tank front wall 11 when sliding along the first tank section, i.e. the door body 2 is more prone to move away from the tank side wall 12 than in the direction away from the tank body 1 when the first tank section is moved, i.e. the door body 2 is more prone to move away from the external environmental member. That means that the door body 2 is more prone to move inwards than to move forward.

The movement of the shaft 311 relatively far from the tank front wall 11 is relatively larger than the movement of the shaft 311 relatively far from the tank side wall 12 when sliding along the second groove section, i.e. the door 2 tends to move further away from the tank front wall 12 than when moving along the second groove section. I.e. the door body 2 is more prone to move forward than to move inward.

When the door body 2 is opened to a first angle, the distance of the door body 2 moving forward is smaller than the distance of the door body 2 moving forward when the shaft body 311 slides along the first groove section, and when the door body 2 is opened to a second angle from the first angle, the distance of the door body 2 moving forward is smaller than the distance of the door body moving forward when the shaft body 311 slides along the second groove section, wherein the second angle is larger than the first angle.

The arrangement of the structure enables the whole first track groove 321 to be in arc extension arrangement, and the arc formed by the first track groove 321 is arched towards the direction deviating from the door outer edge 23, and the whole first track groove 321 is in extension arrangement towards the direction gradually deviating from the box side wall 12 and the box front wall 11.

In the embodiment in which the shaft body 311 is provided on the door body 2 and the groove body 32 is provided on the case body 1, the door body 2 is further apart from the shaft body 31 than the door inner edge 24 is from the door outer edge 23 in the initial stage of opening. The amplitude of the movement of the door outer edge 23 is thus greater in the initial phase of opening of the door body than in the door inner edge 24, which means that the door outer edge 23 is more susceptible to interference by external environmental elements than in the door inner edge 24.

Thus, when the first channel section is moved, the door body 2 is more prone to move inwardly, i.e. away from the side wall 12 of the box, than the door body 2 is to move away from the front wall 11 of the box, i.e. the door body 2 is more prone to move away from the external environmental element to avoid the door outer edge 23 being affected by interference of the external environmental element.

At the time of the second groove section movement, the door body 2 is more prone to move toward the leading side than the door body 2 is to move toward the direction away from the tank side wall 12, that is, more prone to move toward the direction away from the tank front wall 12, that is, the door body 2 is more prone to move toward the direction away from the tank body 1, so as to avoid the door inner edge 24 from being affected by interference of external environmental pieces. The setting of above-mentioned structure can carry out finer control to the opening process of door body 2 according to the actual need of door body 2 opening in-process, can be better avoid door body 2 to receive the interference in the opening process.

In the initial stage of opening the door body 2, the door outer edge 23 is gradually moved toward the plane near the side wall 12 of the box, and then, with further opening of the door body 2, the door outer edge 23 is gradually moved toward the plane far from the side wall 12 of the box. It should be noted that, in this context, the movement toward or away from the tank side wall 12 refers to the movement toward or away from the plane in which the tank side wall 12 lies. Accordingly, movement elsewhere herein with respect to approaching or moving away from the tank front wall 11 refers to movement closer to or away from the plane in which the tank front wall 11 lies.

As shown in fig. 10, when the door body 2 is closed, the second trajectory groove 322 is provided so as to extend in a direction approaching the door front wall 21 and away from the door side wall 22 as a whole, that is, so as to extend in a direction gradually approaching the door front wall 21 and away from the door side wall 22 as a whole from the start end to the end of the second trajectory groove 322. The second track groove 322 is integrally provided to extend away from the door inner edge 24 when the door body 2 is closed.

It is understood that the refrigeration appliance is a refrigerator and is an embedded refrigerator.
