Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of refrigeration and freezing, and particularly to a refrigerator. Background Art
[0002] In the prior art, the door bodies of many refrigerators are double-layer door bodies. Specifically, for example, the door body includes a main door and a sub-door. The main door is used to open and close the storage compartment of the refrigerator, and a second compartment is provided on the main door. The sub-door is used to open and close the second compartment. Two different stoppers need to be provided on the cabinet body to cooperate with the main door and the sub-door. Providing different stoppers for the main door and the sub-door not only increases the assembly process of the refrigerator, but also increases the cost of the refrigerator, which cannot meet the actual needs. Summary of the Invention
[0003] In view of the above problems, the present invention is proposed to provide a refrigerator that overcomes the above problems or at least partially solves the above problems.
[0004] An object of the present invention is to provide a refrigerator with a relatively simple structure.
[0005] In particular, the present invention provides a refrigerator, including:
[0006] A cabinet body, whose front side is open to define a first compartment;
[0007] A first door body, rotatably installed on the front side of the cabinet body to open and close the first compartment, and defining a second compartment;
[0008] A second door body, rotatably installed on the front side of the first door body to open and close the second compartment;
[0009] A stopper, installed on the front side of the cabinet body and adjacent to the hinge end of the first door body;
[0010] A first latch, installed on the first door body, configured to be locked by the stopper after the first door body is closed, so as to apply an elastic resistance to it when the first door body is opened; and
[0011] A second latch, installed on the second door body, configured to be locked by the stopper after the second door body is closed, so as to apply an elastic resistance to it when the second door body is opened.
[0012] Optionally, the stopper is a hook-shaped structure that first extends forward from the front side of the cabinet body and then bends and extends towards the other end of the cabinet body in the transverse direction;
[0013] The first latch includes a first catch, which is hooked on the stopper when the first door body is in the closed state, so as to be locked by the stopper and elastically deformed to disengage from the stopper when the first door body is opened; and
[0014] The second latch includes a second hook that hooks onto the stopper when the second door is in the closed state to be locked by the stopper, and elastically deforms to disengage from the stopper when the second door is opened.
[0015] Optionally, the stopper bends and extends towards the other lateral end of the cabinet while tilting backwards to facilitate the first hook and the second hook to hook onto it.
[0016] Optionally, the first latch and the second latch are respectively located on the upper and lower sides of the stopper.
[0017] Optionally, the stopper further includes a first hinge shaft and a second hinge shaft respectively extending from its upper and lower surfaces.
[0018] The first door is rotatably mounted on the first hinge shaft; and
[0019] The second door is rotatably mounted on the second hinge shaft.
[0020] Optionally, the first latch is provided with a first relief hole through which the first hinge shaft passes;
[0021] The second latch is provided with a second relief hole through which the second hinge shaft passes.
[0022] Optionally, the first latch is mounted on the bottom end surface of the first door;
[0023] The bottom end of the second door has a mounting ear plate extending rearward to the lower side of the first door, and the second latch is mounted on the upper surface of the mounting ear plate.
[0024] Optionally, the rear wall of the first door is provided with an air supply opening and a return air opening, both of which communicate with the first compartment and the second compartment; the rear wall is hollow, and a dew removal air duct communicating with the first compartment is defined inside it, and a plurality of dew removal holes communicating with the second compartment and the dew removal air duct are opened backward on the front surface of the rear wall; the refrigerator is configured to:
[0025] Be in a cooling cycle mode in which the air in the first compartment enters the second compartment through the air supply opening and then returns to the first compartment through the return air opening; or
[0026] Be in a dew removal mode in which the air in the first compartment enters the dew removal air duct so that part of the air flow flows to the front surface of the rear wall through the dew removal holes to remove the condensation on its surface.
[0027] Optionally, the dew removal air duct has an inlet and an outlet communicating with the first compartment; and
[0028] The refrigerator is configured to keep the inlet and the outlet in the closed state and the open state respectively when in the cooling cycle mode; and keep the inlet and the outlet in the open state when in the dew removal mode.
[0029] Optionally, in the direction from the air supply opening to the air return opening, the arrangement density of the dew removal holes gradually decreases.
[0030] The refrigerator of the present invention is a composite door refrigerator and may include a first door body and a second door body. After the first door body and the second door body are closed, the first latch and the second latch can be locked by the same stopper, as opposed to being locked by different stoppers respectively, reducing the number of stoppers, simplifying the structure of the refrigerator, saving the cost of the refrigerator, and simplifying the assembly process of the refrigerator, improving the assembly efficiency of the refrigerator.
[0031] Furthermore, the first latch and the second latch are respectively located on the upper and lower sides of the stopper, which can prevent the first latch and the second latch from affecting each other, thus making the assembly process of the first latch and the second latch simpler.
[0032] Furthermore, through the special design of the first door body, the present invention can effectively remove the condensation on the inner wall of the second compartment. Specifically, the rear wall of the first door body of the present invention is made hollow to define a defrosting air duct, and a plurality of dew removal holes are opened backward on the front surface of the rear wall. When the second compartment needs normal refrigeration, the refrigerator operates in the cooling cycle mode, enabling the air in the first compartment to normally enter the second compartment through the air supply opening to cool the second compartment. When dew condensation occurs on the rear wall surface of the second compartment (i.e., the front surface of the rear wall of the first door body) and dew removal is required, the refrigerator operates in the dew removal mode, enabling the air in the first compartment to enter the dew removal air duct inside the rear wall of the first door body, so that part of the air flow flows to the front surface of the rear wall through the dew removal holes. The relative humidity of the air in the dew removal air duct is necessarily lower than the original air flow at the front surface of the rear wall of the first door body (the relative humidity of the air near the dew condensation is necessarily very high), so the introduction of the low-humidity air in the dew removal air duct can promote the evaporation of the dew condensation.
[0033] Moreover, when the refrigerator of the present invention operates in the dew removal mode, instead of using traditional methods such as electrically heating the rear wall or introducing hot air, it uses the cold air in the first compartment for dew removal, and the dew removal process basically does not affect the normal refrigeration of the second compartment, and the structural design is very ingenious.

[0046] The following describes the refrigerator according to an embodiment of the present invention with reference to Figures 1 to 10 Among them, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. is based on the orientation or positional relationship shown in the drawings, and is 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 orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Arrows are used to indicate the wind direction in each figure.
[0047] Figure 1 is an exploded schematic view of a refrigerator according to an embodiment of the present invention. Refer to Figure 1, the refrigerator according to the embodiment of the present invention generally includes a box body 101, a first door body 102, a second door body 103, a stopper 106, a first latch 104, and a second latch 105. The front side of the box body 101 (in the present invention, the side where the first door body 102 and the second door body 103 are located is taken as the front side of the refrigerator, and the front-back direction has been shown in the figure) is open to define a first compartment 1011. The first door body 102 is rotatably installed on the front side of the box body 101 to open and close the first compartment 1011, and defines a second compartment 1021. The second door body 103 is rotatably installed on the front side of the first door body 102 to open and close the second compartment 1021. The stopper 106 is installed on the front side of the box body 101 and adjacent to the hinge end of the first door body 102. The first latch 104 is installed on the first door body 102 and is adapted to be locked by the stopper 106 after the first door body 102 is closed, so as to apply an elastic resistance to the first door body 102 when it is opened, preventing the first door body 102 from being easily opened. The second latch 105 is installed on the second door body 103 and is adapted to be locked by the stopper 106 after the second door body 103 is closed, so as to apply an elastic resistance to the second door body 103 when it is opened, preventing the second door body 103 from being easily opened.
[0048] In this embodiment, when the first door body 102 is opened, the user stores and retrieves items from the first compartment 1011. When the first door body 102 is closed and the second door body 103 is opened, the user can store and retrieve items from the second compartment 1021. Compared with the existing structure in which two door bodies are respectively provided with independent stopper assemblies, in the present invention, after the first door body 102 and the second door body 103 are closed, the first latch 104 and the second latch 105 can be locked by the same stopper 106, reducing the number of stoppers 106, greatly simplifying the structure of the refrigerator, saving the cost of the refrigerator, and simplifying the assembly process of the refrigerator, improving the assembly efficiency of the refrigerator.
[0049] See Figures 2 to 4 , in an embodiment of the present invention, the stopper 106 is a hook-shaped structure that first extends forward from the front side of the box body 101 and then bends and extends to the other transverse end of the box body 101. The first latch 104 includes a first catch 1042 to hook on the stopper 106 when the first door body 102 is in the closed state, so as to be locked by the stopper 106.
[0050] During the opening process of the first door body 102, the first catch 1042 will undergo elastic deformation and disengage from the stopper 106 to allow the first door body 102 to open smoothly. During the closing process of the first door body 102, the user applies a backward thrust to the first door body 102, prompting the first catch 1042 to move towards the front surface of the stopper 106, causing it to be elastically deformed by being squeezed along the front surface of the stopper 106, and thus entering the rear side of the stopper 106 and entering the locked position. Thus, with the position of the first catch 1042 restricted by the stopper 106, the position of the first door body 102 is very stable. When the pulling force is insufficient and the first catch 1042 is not sufficient to deform and disengage from the stopper 106, the first door body 102 will not open.
[0051] The second lock 105 includes a second catch 1052 to hook on the stopper 106 when the second door body 103 is in the closed state, so as to be locked by the stopper 106.
[0052] During the opening process of the second door body 103, the second catch 1052 will undergo elastic deformation and disengage from the stopper 106 to allow the second door body 103 to open smoothly. During the closing process of the second door body 103, the user applies a backward thrust to the second door body 103, prompting the second catch 1052 to move towards the front surface of the stopper 106, causing it to be elastically deformed by being squeezed along the front surface of the stopper 106, and thus entering the rear side of the stopper 106 and entering the locked position. Thus, with the position of the second catch 1052 restricted by the stopper 106, the position of the second door body 103 is very stable. When the pulling force is insufficient and the second catch 1052 is not sufficient to deform and disengage from the stopper 106, the second door body 103 will not open.
[0053] Continue to refer to Figures 2 to 4 , in an embodiment of the present invention, the stopper 106 bends and extends towards the other lateral end of the box body 101 while tilting backward to facilitate the first catch 1042 and the second catch 1052 to hook thereon.
[0054] Refer to Figure 3 , in an embodiment of the present invention, the first lock 104 and the second lock 105 are respectively located on the upper and lower sides of the stopper 106. The first lock 104 and the second lock 105 being respectively located on the upper and lower sides of the stopper 106 can prevent the first lock 104 and the second lock 105 from affecting each other, thereby making the assembly process of the first lock 104 and the second lock 105 simpler.
[0055] Refer to Figure 2 and Figure 3, in an embodiment of the present invention, the stopper 106 further includes a first hinge shaft 1061 and a second hinge shaft 1062 respectively extending from its upper and lower surfaces. The first door body 102 is rotatably mounted on the first hinge shaft 1061. And the second door body 103 is rotatably mounted on the second hinge shaft 1062. The first hinge shaft 1061 and the second hinge shaft 1062 are respectively located on the upper and lower surfaces of the stopper 106, which can make the positions of the first hinge shaft 1061, the second hinge shaft 1062 and the stopper 106 more compact, so that the positions of the first door body 102 and the second door body 103 are more compact, reducing the space occupied by the first door body 102 and the second door body 103.
[0056] In this embodiment, the stopper 106 not only plays a role in locking the positions of the door bodies (the first door body 102 and the second door body 103), but also serves as a part of the door body hinge structure at the same time. That is to say, the stopper 106 integrates the stopper function and the hinge function, and this structural design is very ingenious, saving the cost of the refrigerator.
[0057] See Figure 3 and Figure 4 , in an embodiment of the present invention, the first latch 104 is provided with a first relief hole 1041. The first hinge shaft 1061 passes through the first relief hole 1041. The second latch 105 is provided with a second relief hole 1051. The second hinge shaft 1062 passes through the second relief hole 1051.
[0058] In this embodiment, during the closing process of the first door body 102, it can drive the first latch 104 to rotate around the first hinge shaft 1061 and then around the stopper 106. During the closing process of the second door body 103, it can drive the second latch 105 to rotate around the second hinge shaft 1062 and then around the stopper 106, and it is relatively easy to realize the locking of the stopper 106 to the first latch 104 and the second latch 105.
[0059] See Figure 5 , in an embodiment of the present invention, the first latch 104 is mounted on the bottom end surface of the first door body 102. The bottom end of the second door body 103 has a mounting ear plate 1031 extending backward to the lower part of the first door body 102. The second latch 105 is mounted on the upper surface of the mounting ear plate 1031.
[0060] In this embodiment, since the mounting ear plate 1031 extends to the lower part of the first door body 102, the positional relationship between the first door body 102 and the second door body 103 can be made more compact, and thus the second compartment 1021 of the first door body 102 can be more tightly closed after the second door body 103 is closed.
[0061] See Figure 6, in some other embodiments, the stopper 106 is a hook-shaped structure that first extends forward from the front side of the cabinet 101 and then bends and extends toward the other lateral end of the cabinet 101 to form a plurality of hooks. Specifically, for example, the stopper 106 is a hook-shaped structure that extends toward the other lateral end of the cabinet 101 to form a first hook 1063 and a second hook 1064. The first latch 104 can be hooked on the first hook 1063, and the second latch 105 can be hooked on the second hook 1064.
[0062] In some other embodiments, the refrigerator can be refrigerated by a vapor compression refrigeration cycle system, a semiconductor refrigeration system, or other means. According to different refrigeration temperatures, each compartment inside the refrigerator can be divided into a refrigerating compartment, a freezing compartment, and a variable-temperature compartment. For example, the temperature inside the refrigerating compartment is generally controlled between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside the freezing compartment is generally controlled between -22°C and -14°C. The variable-temperature compartment can be adjusted between -18°C and 8°C to achieve a variable-temperature effect. The optimal storage temperatures for different types of items are not the same, and the suitable storage compartments are also not the same. For example, fruits and vegetables are suitable for storage in the refrigerating compartment, while meat is suitable for storage in the freezing compartment. The first compartment 1011 of the embodiment of the present invention is preferably a refrigerating compartment.
[0063] In the existing double-door refrigerator, condensation often occurs on the inner wall of the door compartment (the second compartment 1021 in the present invention). The inventor realizes that since the rear wall 211 of the first door body 102 is adjacent to the first compartment 1011, heat transfer can occur between the rear wall 211 and the air in the first compartment 1011 through heat conduction. Therefore, the temperature on the front surface of the rear wall 211 is lower than that of the other walls of the second compartment 1021, and condensation is more likely to occur.
[0064] Based on the above understanding, in the embodiment of the present invention, the first door body 102 is specially designed to dehumidify the front surface of the rear wall 211 of the second compartment 1021. Specifically, an air supply port 212 and an air return port 214 are opened on the rear wall 211 of the first door body 102, and both are communicated with the first compartment 1011 and the second compartment 1021. Moreover, the rear wall 211 of the first door body 102 is hollow, and a dehumidifying air duct 215 communicating with the first compartment 1011 is defined inside it. That is, the hollow space of the rear wall 211 constitutes the dehumidifying air duct 215. A plurality of dehumidifying holes 2154 communicating with the second compartment 1021 and the dehumidifying air duct 215 are opened backward on the front surface of the rear wall 211. The refrigerator is configured to be in a cooling cycle mode in which the air in the first compartment 1011 enters the second compartment 1021 through the air supply port 212 and then returns to the first compartment 1011 through the air return port 214, so as to use the cold air in the first compartment 1011 to refrigerate the second compartment 1021, such as Figure 7 and Figure 8Alternatively, the refrigerator is in a dew removal mode in which the air in the first compartment 1011 enters the dew removal air duct 215, so that part of the air flow flows through the dew removal holes 2154 to the front surface of the rear wall 211 to remove the condensation on its surface, such as Figure 9 and Figure 10 .
[0065] In the embodiment of the present invention, the refrigerator is in the aforementioned cooling cycle mode under normal conditions. However, when wet air is introduced due to door opening and closing operations or high-humidity storage items are placed, and there is a lot of condensation on the front surface of the rear wall 211 of the first door body 102, the refrigerator can be controlled to operate in the aforementioned dew removal mode, so that the air in the first compartment 1011 enters the dew removal air duct 215 inside the rear wall 211 of the first door body 102, so that part of the air flow flows through the dew removal holes 2154 to the front surface of the rear wall 211. Since the relative humidity of the air in the dew removal air duct 215 must be lower than the relative humidity of the original air flow on the front surface of the rear wall 211 of the first door body 102 (the relative humidity of the air near the condensation must be very high), the low-humidity air introduced into the dew removal air duct 215 can promote the evaporation of the condensation and complete the dew removal process. After the dew removal is completed, the refrigerator can be controlled to switch to the cooling cycle mode.
[0066] The switching timing between the cooling cycle mode and the dew removal mode can be automatically controlled by the refrigerator, such as switching at a fixed time or automatically switching the operating mode of the refrigerator according to the detection result of the humidity sensor. It can also be manually controlled. For example, when the user finds that dew removal is needed or dew removal needs to be stopped, the user can manually switch the operating mode of the refrigerator.
[0067] When the refrigerator in the embodiment of the present invention operates in the dew removal mode, it does not adopt traditional methods such as electrically heating the rear wall 211 or introducing hot air. Instead, it still uses the cold air in the first compartment 1011 for dew removal, and the dew removal process basically does not affect the normal refrigeration of the second compartment 1021. The structural design is very ingenious.
[0068] In some embodiments, such as Figure 7 and Figure 9As shown, the dew removal air duct 215 can be provided with an inlet 2151 and an outlet 2152 communicating with the first compartment 1011, so as to form an air path circulation between the dew removal air duct 215 and the first compartment 1011, avoiding the accumulation of the air flow for dew removal near the dew removal air duct 215 and the dew removal holes 2154 and preventing it from flowing, which may affect the dew removal effect. In addition, the refrigerator is configured such that when in the cooling cycle mode, the inlet 2151 and the outlet 2152 are respectively in the closed state and the open state; when in the dew removal mode, both the inlet 2151 and the outlet 2152 are in the open state. That is to say, in the cooling cycle mode, only the inlet 2151 of the dew removal air duct 215 needs to be closed. When in the dew removal mode, the inlet 2151 of the dew removal air duct 215 is opened. Since the on-off control of the inlet 2151 and the outlet 2152 of the dew removal air duct 215 has been used to control the conduction and closure of the dew removal air duct 215, there is no need to control the outlet 2152 of the dew removal air duct 215. In both modes, the outlet 2152 of the dew removal air duct 215 is in the normally open state and does not need to be controlled, so as to simplify the structure and control of the refrigerator.
[0069] In some embodiments, as Figure 7 and Figure 9 shown, the inlet 2151 of the dew removal air duct 215 can penetrate the side wall of the air supply opening 212 to communicate with the air supply opening 212. That is, the dew removal air duct 215 borrows the air supply opening 212 to communicate with the first compartment 1011, and there is no need to open another hole in the rear wall 211. The outlet 2152 of the dew removal air duct 215 can also penetrate the side wall of the air return opening 214 to communicate with the air return opening 214. That is, the dew removal air duct 215 borrows the air return opening 214 to communicate with the first compartment 1011, and there is no need to open another hole in the rear wall 211. This design structure is very ingenious, simplifies the opening structure of the rear wall 211 of the first door body 102, and only the air supply opening 212 and the air return opening 214 need to be directly opened on the rear surface of the rear wall 211 of the first door body 102.
[0070] In some embodiments, as Figure 7 and Figure 9 shown, the air supply opening 212 and the air return opening 214 are respectively located at the top and the bottom of the rear wall 211. When the refrigerator is in the cooling cycle mode, after the cold air flows into the second compartment 1021 from the air supply opening 212, due to its relatively large density and having a sinking effect, it will flow downward and sequentially cool each height area of the second compartment 1021, and then flow back to the first compartment 1011 from the air return opening 214 at the bottom of the second compartment 1021 after the air temperature gradually rises. In this way, a more smooth air path circulation is formed, improving the cooling effect of the second compartment 1021. When the refrigerator is in the dew removal mode, the cold air enters the dew removal air duct 215 from the top of the dew removal air duct 215, which is also more conducive to flowing downward, making the dew removal air duct 215 have better fluidity and facilitating the acceleration of the dew removal process.
[0071] AsFigure 8 and Figure 10 As shown, the refrigerator may further include an air damper 216, which is installed at the air supply port 212 and configured to be controllably moved to a cooling state where the inlet 2151 is closed and the air supply port 212 is opened (as shown in Figure 8 ), or moved to a dew removal state where the inlet 2151 is opened and the air supply port 212 is closed (as shown in Figure 10 ). This embodiment effectively utilizes the advantage that the inlet 2151 is connected to the air supply port 212, and uses one air damper 216 to control both the air supply port 212 and the inlet 2151 at the same time, simplifying the air inlet and outlet control, and the design is very ingenious.
[0072] Specifically, as shown in Figure 8 and Figure 10 , one end of the air damper 216 can be rotatably installed at the front edge of the inlet 2151, so as to be rotated to the cooling state (as shown in Figure 8 ) or the dew removal state (as shown in Figure 10 ). In the embodiment of the present invention, there is no need to set up a complex movement mechanism and control logic. By only controlling the rotation of one air damper 216, the switching of the operation mode of the refrigerator can be completed, and both the structure and the control are greatly simplified.
[0073] In some embodiments, as shown in Figures 7 to 10 , the refrigerator further includes a fan 230, which is located at the air supply port 212 to promote the air in the first compartment 1011 to flow towards the air supply port 212 to accelerate the cooling cycle speed. Of course, for the solution where the inlet 2151 is connected to the air supply port 212, the fan 230 is also used to promote the air in the first compartment 1011 to flow towards the dew removal duct 215.
[0074] The inventor realized that the more close to the air supply port 212, the more dew condensation is generated on the rear wall 211 of the first door body 102, and the closer to the air return port 214, the less dew condensation. Therefore, in the embodiment of the present invention, the arrangement density of the dew removal holes 2154 is specifically designed. In the direction from the air supply port 212 to the air return port 214, the arrangement density of the dew removal holes 2154 is gradually reduced to match the change trend of the dew condensation degree at different positions of the rear wall 211 of the first door body 102, and reduce excessive meaningless openings. The opening area of the rear wall 211 of the first door body 102 can cover the entire front surface of the rear wall 211 to achieve sufficient dew removal, or it can cover a part of the front surface of the rear wall 211. The opening rate of the dew removal holes 2154 can be 30% - 80%. The dew removal holes 2154 can be arranged in a matrix or other arrangements. The dew removal holes 2154 can be circular, oval, square or other shapes. Preferably, the dew removal holes 2154 are long strip-shaped holes with the length direction parallel to the air flow direction of the dew removal duct 215. This structure is conducive to destroying the integrity of the dew drops and accelerating the dispersion and evaporation of the dew drops.
