Detailed Description

The present embodiment provides a refrigerator 100, and for convenience of description, the orientations of "up", "down", "front", "back", "top", "bottom", "lateral", and the like referred to in the specification are defined according to the spatial position relationship in the normal operation state of the refrigerator 100. Here, the lateral direction refers to a direction parallel to the width direction of the refrigerator 100. The refrigerator of the present embodiment is described in detail below with reference to fig. 1 to 7.

The refrigerator 100 includes a cabinet 110 having a first storage container 120, a first door 101, a hinge 140, a sleeve 101a, and a rolling body 103. The first storage inner container 120 has a first access opening for accessing articles, a shaft sleeve 101a is disposed at a lower end of the first door 101, the hinge 140 is disposed on the box body 110, the hinge 140 has a hinge shaft 143, and the hinge shaft 143 is pivotally received in the shaft sleeve 101a, so that when the first door 101 rotates around the hinge shaft 143 under an external force, the first access opening is opened or closed. The rolling body 103 is also disposed at a lower end of the first door body 101, and the hinge 140 is further formed with an opening groove 142 and a closing groove 141, and when the first door body 101 is operated to rotate between opening and closing, the rolling body 103 rotates between the opening groove 142 and the closing groove 141. So through the cooperation between rolling element 103 and the recess 142 and the recess 141 of closing the door, compare in the current scheme and directly adopt the switching door scheme of taking lubricating oil between hinge pin 143 and the axle sleeve 101a, the smoothness of the first door body 101 switching has been increased, moreover, rolling element 103 is located the lower extreme of first door body 101, easily make first door body 101 close tightly with the help of the gravity of first door body 101, thereby can cancel the magnetic stripe in the door seal, still can guarantee that first door body 101 is sealed tight, reduce the heat leakage problem of first door body 101 and door seal, reduce the whole energy consumption of refrigerator 100.

As will be appreciated by those skilled in the art, the dock seal is typically disposed on the inner periphery of the door body, and the dock seal inside the first door body 101 is not shown. The rolling body 103 may be a ball, a needle, or the like, and the rolling body 103 is disposed at a lower end of the first door body 101 through a support shaft. The hinge 140 may be disposed at the front end of the bottom of the first storage bladder 120, i.e., at the front end of the cross member 121 disposed between the first storage bladder 120 and a second storage bladder described below.

Further, as shown in fig. 6, the hinge 140 may have a curved platform 144 between the door opening groove 142 and the door closing groove 141 on a rotation path of the rolling body 103, and the curved platform 144 includes an upper curved section 144a, a horizontal straight section 144b, and a lower curved section 144c sequentially extending from the door opening groove 142 to the door closing groove 141 on the rotation path of the rolling body 103. The upper inclined curved section 144a extends obliquely upward from the inner side edge of the door opening groove 142, the horizontal straight section 144b extends horizontally from the upper inclined curved section 144a, and the lower inclined curved section 144c extends obliquely downward from the horizontal straight section 144b to the inner side edge of the door closing groove 141. In the door opening state, the rolling body 103 is located in the door opening groove 142, in the door closing process, the rolling body 103 gradually runs from the door opening groove 142 to the upper inclined curved section 144a, a certain thrust is required in the process, then the door is continuously closed, the rolling body 103 moves from the upper inclined curved section 144a to the horizontal straight section 144b, the required door closing thrust is smaller, then the door is continuously closed, the rolling body 103 moves from the horizontal straight section 144b to the lower inclined curved section 144c, at the moment, the rolling body 103 automatically slides downwards to the door closing groove 141 under the gravity action of the first door body 101 along the lower inclined curved section 144c, no external force is applied in the process, the first door body 101 can be automatically closed, the pressing fit and the sealing with the box body 110 are realized, and the sealing of the first door body 101 can be ensured under the condition that the magnet is eliminated.

To further increase the smoothness and sealing property of the closing of the first door body 101, referring to fig. 6 again, the cross section of the door-closing groove 141 in the vertical direction includes a first curved section 141a and a second curved section 141b sequentially extending from the inner side to the outer side, the first curved section 141a extends downward from the inner side, the second curved section 141b extends upward from the outer side of the first curved section 141a, and the curvature of the first curved section 141a is greater than that of the second curved section 141 b. That is, the door-closing groove 141 is irregular, and during the door-closing process of the first door 101, the rolling element 103 moving from the door-opening groove 142 to the curved platform 144 slides to the bottom of the groove along the first curved segment 141a inclined downward, so that the rolling element 103 slides to the bottom of the groove easily by means of the downward extension trend of the first curved segment 141a and the gravity of the first door 101, and the rolling element 103 is limited in the door-closing groove 141 due to the blocking of the second curved segment 141b extending upward and having a larger curvature, thereby achieving the automatic closing of the first door 101.

In some embodiments, the transverse extension line L2 of the lowest point of the door passing groove 141 is closer to the box 110 than the transverse extension line L1 of the center of the hinge shaft 143, so as to ensure that when the rolling element 103 moves to the bottom of the door passing groove 141, there is still a tendency and power to move in the direction of the box 110, that is, the first door 101 has power to move continuously toward the box 110, and only because the first door 101 is supported by the periphery of the box 110, the first door 101 cannot move continuously toward the box 110 side, so that the closing force is increased, and the sealing performance of the first door 101 is improved.

The door opening groove 142 may also have a special design to increase the smoothness of opening the door, and referring to fig. 6, a cross section of the door opening groove 142 in a vertical direction includes a third curved section 142a and a fourth curved section 142b sequentially extending from an inner side to an outer side, the third curved section 142a extends downward from the inner side, the fourth curved section 142b extends upward from the outer side of the third curved section 142a, and a curvature of the third curved section 142a is greater than a curvature of the fourth curved section 142 b. In the door opening process of the first door body 101, the rolling body 103 moving from the door closing groove 141 to the curved platform 144 continues to move along the downwardly extending third curved segment 142a to the bottom of the door opening groove 142, so that the rolling body 103 is easily slid to the bottom of the door opening groove 142 by virtue of the downward extending trend of the third curved segment 142a and the gravity of the first door body 101, and the rolling body 103 is limited in the door opening groove 142 due to the blocking of the upwardly extending fourth curved segment 142b with a large bending degree, thereby realizing the automatic and smooth opening of the first door body 101.

The depths of the door-closing groove 141 and the door-opening groove 142 are both less than or equal to 1mm, so that the external force required by the rolling body 103 when moving between the door-closing groove 141 and the door-opening groove 142 is small, and the first door body 101 is easy to open and close smoothly.

The embodiment is directed at the opening and closing scheme of the rotating shaft type side-opening door body, and the pressing and sealing of the door body can be guaranteed and the heat leakage of the door body and the door seal can be reduced under the condition of no magnet by adopting the special design.

For the rotating shaft type side-opening door body with the magnet or the push-pull type drawer-type door body, the embodiment additionally provides other special design schemes so as to achieve the effect of reducing heat leakage of the door body and the door seal. Specifically, referring to fig. 3 and 7, the box body 110 further includes a second storage liner 130, two second door bodies 102 and two door seals, the second storage liner 130 has a second access opening for accessing the articles, the second storage liner 130 has a central beam 131 extending in the transverse direction at the second access opening, the two second door bodies 102 are distributed at the second access opening in an up-and-down manner and configured to respectively open or close a space above the central beam 131 and a space below the central beam 131 of the second storage liner 130, the two door seals are respectively disposed on the inner peripheries of the two second door bodies 102, a boss 131a protruding toward the second door body 102 is formed on an end surface of the middle beam 131 facing the second door body 102, an accommodating space is formed in the boss 131a, the refrigerator 100 further includes an exposure removing pipe, the exposure removing pipe has a horizontal pipe section 104 extending along the transverse direction, and the horizontal pipe section 104 is accommodated in the accommodating space.

The dewing pipe is a common component of the refrigerator 100, and plays a role of preventing the door seal from being dewed. Among the current refrigerator 100, the distance of the door body and centre sill 131 front end is generally greater than 100mm, both clearances are great, the air circulation velocity of flow is high, the heat convection coefficient is big, leak heat is many, the easy condensation of door seal rear side, the horizontal pipe segment 104152 except that the dew pipe is nearer with the storing space's that second storing inner bag 130 was injectd distance moreover, when outside radiating, a large amount of heats have also spread into storing space's inside, it is great to cause the temperature distribution difference in the storing space.

In the embodiment, by the special design of the center sill 131, the gap between the center sill 131 and the second door 102 is reduced, the degree of heat convection at the gap is reduced, and heat leakage between the door seal and the second door 102 is reduced, so that the effect of reducing energy consumption of the refrigerator 100 is achieved; moreover, the horizontal pipe section 104 of the dew removing pipe is arranged in the accommodating space limited by the boss 131a and is far away from the storage space, so that the heat diffused into the storage space is reduced, the temperature distribution difference condition in the storage space is reduced, and the energy consumption of the refrigerator is reduced.

In this embodiment, the second door 102 may be a hinge side-opening door or a push-pull drawer door, and a magnet (not numbered) is disposed in a door seal disposed on the inner side of the second door 102.

The distance between the end surface of the second door body 102 facing the boss 131a and the end surface of the boss 131a facing the second door body 102 is less than or equal to 5 mm. Compared with the refrigerator 100 in which the distance between the door body and the front end of the center sill 131 is greater than or equal to 100mm in the prior art, in the refrigerator 100 of the embodiment, the distance between the boss 131a and the second door body 102 is short, so that heat leakage of the second door body 102 and the door seal is reduced, and the heat load of the refrigerator 100 is further reduced.
