Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A refrigerator 1000 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

The refrigerator 1000 according to an embodiment of the present invention, as shown in fig. 1 to 3, includes: refrigerator door 100, ice maker body 210, ice maker door 220, and door lock assembly 400. The ice maker body 210 is disposed on the refrigerator door 100, one side of the ice maker body 210 is opened to form the ice making chamber 200, and the ice maker door 220 is disposed on the ice maker body 210 to open or close the ice making chamber 200.

Here, the ice maker body 210, the ice maker door 220, and other structures inside the ice maker body 210 constitute an ice maker. The ice maker may be disposed on a freezing chamber door of the refrigerator 1000, and the ice maker may also be disposed on a refrigerating chamber door of the refrigerator 1000, that is, the refrigerator door 100 may be either the freezing chamber door or the refrigerating chamber door, and is not particularly limited herein. However, since the capacity of the freezer compartment is generally small, the ice maker is disposed in the freezer compartment having a small capacity, which leads to a further reduction in the capacity of the freezer compartment, and therefore, most products have the ice maker disposed in the cold storage area.

One of the ice maker body 210 and the ice maker door 220 constitutes a first mounting body, and the other of the ice maker body 210 and the ice maker door 220 constitutes a second mounting body. It should be noted that the terms "first mounting body" and "second mounting body" are used herein for convenience of description of the following structures.

Specifically, the component a is disposed on the first mounting body, and the component B is disposed on the second mounting body, which means that the component a can be disposed on both the ice maker body 210 and the ice maker door 220. When the a component is disposed on the icemaker body 210, the B component is disposed on the icemaker door 220. When the a component is disposed on the ice maker door 220, the B component is disposed on the ice maker body 210. That is, the noun citation of the "first installation body" and the "second installation body" is convenient to express the two schemes through one description, and will not be described later.

In addition, the following will refer to terms of "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, which are based on the orientation or positional relationship shown in the drawings, for convenience in describing the invention and for simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the invention.

For convenience of explanation, when the refrigerator door 100 is opened and the user faces the ice maker, the side of the ice maker facing the user is set to be front, the side facing away from the user is set to be rear, the side facing the left hand of the user is set to be left, and the side facing the right hand of the user is set to be right. In this structure of the ice maker of this document, as shown in fig. 1 and 2, the ice maker door 220 is provided on the front side of the ice maker body 210.

Referring to fig. 3 and 4, the door lock assembly 400 includes: the movable member 410, the first locking member 420, the second locking member 430 and the elastic member 440 are rotatably disposed on the first mounting body between a locking position and a releasing position, and the elastic member 440 is connected between the movable member 410 and the first mounting body to normally drive the movable member 410 to rotate toward the locking position. Here, "normally" refers to the normal state, and "normally actuated" means that the elastic member 440 has a tendency to be pulled or pushed toward a certain direction with respect to the movable member 410, so that when the movable member 410 is moved away from the engagement position, the elastic force of the elastic member 440 rotates the movable member 410 toward the engagement position.

One of the first latch 420 and the second latch 430 is disposed on the movable member 410, and the other of the first latch 420 and the second latch 430 is disposed on the second mounting body. The first latch 420 and the second latch 430 can be in a snap fit to lock the ice maker door 220 at the latching position, and the first latch 420 and the second latch 430 are out of a fit to unlock the ice maker door 220 at the releasing position.

Therefore, when the ice maker door body 220 is closed, if the ice making chamber 200 needs to be opened, the movable member 410 can be triggered to rotate from the buckling position to the releasing position, so that the first buckling member 420 is separated from the second buckling member 430, the ice maker door body 220 is in the unlocking state, and the ice maker door body 220 can be opened at this time. When the movable member 410 is released, the movable member 410 rotates to the fastening position under the elastic force of the elastic member 440.

When the ice maker door 220 is opened, if the ice making chamber 200 needs to be closed, the ice maker door 220 can be directly closed, so that the first fastener 420 is fastened with the second fastener 430. Then, under the driving of the elastic force of the elastic member 440, the movable member 410 is kept at the buckling position, so that the first buckling member 420 and the second buckling member 430 are kept in the buckling state, and the locking of the ice maker door body 220 is kept. Thus, the ice maker door 220 may be always locked by the door lock assembly 400 to prevent the leakage of cold air in the ice making compartment 200.

Also, in some products, the ice maker door 220 has a door seal 500. Under the condition that the ice maker door 220 is closed, if the movable element 410 is triggered to separate the first locking element 420 from the second locking element 430 and unlock the ice maker door 220, the elastic force of the door seal 500 can automatically push the ice maker door 220 open, and the movable element 410 does not need to lock the ice maker door 220 after the movable element 410 is loosened. Therefore, the ice maker door body 220 is automatically opened after the movable piece 410 is triggered, and labor is saved for opening the door.

As can be seen from the above description, the ice maker door 220 can be locked by the door lock assembly 400, and the ice maker door 220 is very convenient to open. The door lock assembly 400 comprises a few parts and is simple in structure, the door lock assembly 400 occupies a small area under reasonable arrangement, the problem that the insulating layer of the ice maker body 210 or the ice maker door body 220 at the installation position of the door lock assembly 400 is too thin can be avoided, and the risk of condensation on the ice making chamber 200 is avoided.

According to the refrigerator 1000 of the embodiment of the invention, the door lock assembly 400 is arranged between the ice maker door 220 and the ice maker body 210, so that not only can the ice maker door 220 be locked to avoid cold air in the ice making chamber 200 from leaking, but also the opening and closing operation of the ice maker door 220 is very simple and labor-saving, and a door handle dropping structure can be saved on the ice maker door 220. The door lock assembly 400 has a simple structure, occupies a small area, has a large design space, and facilitates the aesthetic design of the ice maker. In addition, the problem that the insulating layer of the ice maker body 210 or the ice maker door 220 is too thin at the installation position of the door lock assembly 400 can be avoided, and the risk of condensation on the ice making chamber 200 door is avoided.

In some embodiments, as shown in fig. 3 to 5, the first locking member 420 is formed as a hook 421, the second locking member 430 is provided with a locking hole 431, and the head 4211 of the hook 421 is hooked in the locking hole 431 in the locking position. The first fastener 420 and the second fastener 430 with such a structure have a simple structure, are easy to process, and can make the occupied volume of the door lock assembly 400 smaller.

Of course, in the embodiment of the present invention, the first locking member 420 and the second locking member 430 may also be formed as the locking hook 421, and the first locking member 420 and the second locking member 430 may also adopt other locking structures disclosed in the prior art, which is not described in detail herein.

When the hook 421 is disposed on the ice making machine door 220, the lock hole 431 is disposed on the ice making machine body 210. When the hook 421 is disposed on the ice maker body 210, the locking hole 431 is disposed on the ice maker door 220.

Specifically, as shown in fig. 4, a surface of the second locking member 430 facing the first locking member 420 is provided with a guide surface 432 for guiding the head 4211 of the hook 421 to slide into the locking hole 431, and in a direction away from the locking hole 431, the guide surface 432 extends in a direction away from the first locking member 420.

It can be understood that the rotation direction of the movable element 410 is the same as the direction in which the head 4211 of the hook 421 extends into the locking hole 431, when the movable element 410 rotates from the locking position to the releasing position, the head 4211 of the hook 421 can be disengaged from the locking hole 431, and when the movable element 410 rotates from the releasing position to the locking position, the head 4211 of the hook 421 can be hooked with the locking hole 431.

When the ice maker door 220 needs to be closed, the ice maker door 220 can be directly closed. Thus, under the action of the closing force, the ice maker door 220 is gradually closed, and the distance between the hook 421 and the second locking member 430 is gradually reduced until the hook 421 presses on the guide surface 432.

Since the guide surface 432 extends in a direction away from the lock hole 431 toward a direction away from the first latch 420, in the process that the head 4211 of the hook 421 slides along the guide surface 432 toward the lock hole 431, the first latch 420 generates a component force perpendicular to the opening and closing direction of the ice maker door 220 to the second latch 430, and the second latch 430 also generates a component force perpendicular to the opening and closing direction of the ice maker door 220 to the first latch 420, where the direction indicated by an arrow M in fig. 4 is a direction perpendicular to the opening and closing direction of the ice maker door 220.

If the second locking element 430 is connected to the movable element 410 and the second locking element 430 can rotate along with the movable element 410, the component force can make the second locking element 430 rotate in a direction away from the first locking element 420, so that the ice maker door 220 can be smoothly closed in place. During the rotation of the second latch 430, the movable member 410 rotates to the release position. After the head 4211 of the hook 421 slides into the locking hole 431, the movable member 410 returns to the locking position under the action of the elastic member 440, and the second locking member 430 returns to the original position, so that the head 4211 of the hook 421 is hooked in the locking hole 431, and the ice maker door 220 can be smoothly locked.

Similarly, if the first locking element 420 is connected to the movable element 410, and the first locking element 420 can rotate along with the movable element 410, the component force can make the first locking element 420 rotate towards the direction away from the guide surface 432, so that the ice maker door 220 can be smoothly closed in place. During the rotation of the first latch 420, the movable member 410 rotates to the release position. After the head 4211 of the hook 421 slides into the locking hole 431, the movable element 410 returns to the locking position under the action of the elastic element 440, and the first locking element 420 returns to lock the ice maker door 220.

As shown in fig. 4, the first locking member 420 is located at the front side of the second locking member 430, the rear end of the first locking member 420 extends leftward to form a head 4211 of the hook 421, and the first locking member 420 moves from front to back when the door is closed. Of the front surfaces of the second latches 430, the surface on the left side of the locking hole 431 is formed as a slope extending forward to the left.

In the process of closing the ice maker door 220, the first fastening member 420 moves from the front to the back towards the second fastening member 430, when the head 4211 of the hook 421 abuts against the guide surface 432, the guide surface 432 applies pressure to the hook 421, so that the first fastening member 420 rotates rightwards, until the head 4211 rotates into the lock hole 431, the movable member 410 returns to the fastening position under the elastic force of the elastic member 440, and the first fastening member 420 is driven to be fastened on the second fastening member 430, thereby ensuring that the ice maker door 220 can be locked.

In the embodiment of the present invention, the first locking member 420 may be an elastic hook, and the first locking member 420 may also be a rigid hook, which is not limited herein.

In some embodiments, as shown in fig. 3 and 4, the second locking member 430 is formed as a locking ring 433, the locking ring 433 is recessed toward a direction away from the hook 421 to form a hole 4331, an opening of the hole 4331 forms a locking hole 431, and an inner peripheral wall of the hole 4331 is provided with a locking block 4332 for hanging the head 4211 of the hook 421.

Specifically, if the second catch 430 is disposed on the ice maker body 210, the second catch 430 may be disposed inside the ice maker body 210. The ice maker body 210 is provided with an open slot 244, the lock hole 431 of the second locking member 430 can be arranged opposite to the open slot 244, and the hook 421 can extend into the hole 4331 through the open slot 244.

The locking ring 433 is separately arranged to be matched with the hook 421, and the locking ring 433 can be arranged to be an independent piece with better material quality and durability, so that the ice maker body 210 or the ice maker door 220 cannot be damaged too much when the hook 421 is repeatedly hooked in the locking hole 431.

In some embodiments, the first mounting body defines the accommodating cavity 240, the movable member 410 and the elastic member 440 are both disposed in the accommodating cavity 240, a first through hole 241 communicating with the accommodating cavity 240 is disposed on a surface of the first mounting body, and the first locking member 420 or the second locking member 430 connected to the movable member 410 extends out of the first through hole 241.

For convenience of description, hereinafter, the first installation bodies refer to the ice maker door 220, the second installation bodies refer to the ice maker body 210, that is, the movable member 410 is disposed on the ice maker door 220, wherein the movable member 410 is connected to the first locking member 420, and the second locking member 430 is disposed on the ice maker body 210. Of course, when the movable member 410 is disposed on the ice maker body 210, the structure of the door lock assembly 400 can be derived from the condition that the movable member 410 is disposed on the ice maker door 220, and will not be described in detail below. In addition, the second locking member 430 may also be disposed on the movable member 410, and the structure of the door lock assembly 400 may also be derived from the condition that the first locking member 420 is disposed on the movable member 410, which is not described in detail below.
