[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art
[0002] A freezer is a household or commercial appliance used to refrigerate or freeze food and items. It usually uses refrigeration technology to keep the temperature at a lower level to keep the food fresh and extend its shelf life.
[0003] In the prior art, a refrigerator includes an inner box and an outer box, wherein the inner box is arranged inside the outer box. A drain pipe is arranged between the inner box and the outer box, and a drain port is provided on the outer box. The drain pipe is connected to the drain port so that the water inside the inner box can be discharged through the drain pipe and the drain port. It can be used to discharge condensed water or sewage when cleaning the inner box.
[0004] However, the refrigerators in the prior art have different models, and for different models, the distance between the bottom wall of the outer box and the bottom wall of the inner box is different. Therefore, the drain pipe also needs to be set to different lengths for different models, and it is impossible to meet the needs of using one drain pipe for different models, and the degree of universality is low. Utility Model Content
[0005] The utility model solves one of the technical problems in the related art at least to a certain extent.
[0006] To this end, the present application aims to provide a refrigerator in which a first drain pipe and a second drain pipe are slidably connected. Therefore, for different refrigerator models, when the distance between the bottom wall of the outer box body and the bottom wall of the inner box body is different, the first drain pipe and the second drain pipe slide to the corresponding distance accordingly, and can be adjusted according to different needs. It is suitable for various models of refrigerators and has a high degree of commonality.
[0007] In order to achieve the above object, the utility model provides a refrigerator, comprising:
[0008] An outer box body, wherein the top of the outer box body is open;
[0009] An inner box body, the inner box body is arranged inside the outer box body, and the top of the inner box body is arranged with an opening corresponding to the opening of the outer box body;
[0010] a first drain port, the first drain port penetrating through the bottom wall of the inner box;
[0011] a second drain port, the second drain port penetrating through the bottom wall of the outer box;
[0012] A first drain pipe, wherein the first drain pipe is disposed between the bottom wall of the outer box and the bottom wall of the inner box, and the top end of the first drain pipe is connected to the first drain port;
[0013] A second drain pipe, the bottom end of the second drain pipe is connected to the second drain port; the top end of the second drain pipe is plugged into the bottom end of the first drain pipe; the second drain pipe and the first drain pipe can slide with each other; the outer peripheral wall of the second drain pipe is sealed and connected to the inner peripheral wall of the first drain pipe.
[0014] In the technical solution, the first drain pipe and the second drain pipe are connected by sliding, so when the distance between the bottom wall of the outer box and the bottom wall of the inner box is different for different refrigerator models, the first drain pipe and the second drain pipe slide to the corresponding distance accordingly, and can be adjusted according to different needs, suitable for refrigerators of various models, and have a high degree of universality. During adjustment, the top end of the second drain pipe slides inside the bottom end of the first drain pipe, because the outer peripheral wall of the second drain pipe is sealed with the inner peripheral wall of the first drain pipe, thereby avoiding the possibility of sewage leaking out of the second drain pipe, and avoiding sewage dripping into the inner part of the outer box.
[0015] In addition, the present application also provides a refrigerator, which includes:
[0016] An outer box body, wherein the top of the outer box body is open;

[0018] a first drain port, the first drain port penetrating through the bottom wall of the inner box;
[0019] a second drain port, the second drain port penetrating through the bottom wall of the outer box;
[0020] A first drain pipe, wherein the first drain pipe is disposed between the bottom wall of the outer box and the bottom wall of the inner box, and the top end of the first drain pipe is connected to the first drain port;
[0021] A second drain pipe, wherein the bottom end of the second drain pipe is connected to the second drain port; and the top end of the second drain pipe is sleeved on the bottom end of the first drain pipe.
[0022] In the technical solution, the first drain pipe and the second drain pipe are connected by sliding. Therefore, when the distance between the bottom wall of the outer box and the bottom wall of the inner box is different for different refrigerator models, the first drain pipe and the second drain pipe slide to the corresponding distance accordingly, and can be adjusted according to different needs. It is applicable to refrigerators of various models and has a high degree of universality. During adjustment, the bottom end of the first drain pipe slides inside the top end of the second drain pipe. Because the bottom end of the first drain pipe is located inside the second drain pipe, there is no possibility of sewage leaking outside the second drain pipe, and sewage is prevented from dripping into the outer box.
[0023] In some embodiments of the present application, the top end of the second drain pipe is expanded in a direction toward the first drain pipe.
[0024] In the technical solution, during installation, the expansion is used for guidance, which makes it easier to insert the first drain pipe into the second drain pipe, thereby facilitating installation and improving installation efficiency.

It is easy to install. And the first accommodating cavity can accommodate the limiting ring to prevent the limiting ring from protruding from the inner bottom wall of the inner box, which is convenient for placing goods in the inner box.
[0028] In some embodiments of the present application, a first annular groove is formed on a side of the first limiting ring facing the second drain outlet; a first sealing ring is disposed in the first annular groove.
[0029] In the technical solution, the first sealing ring is accommodated by the first ring groove, and the first sealing ring is used to seal the first limiting ring and the inner bottom wall of the inner box body to prevent sewage from leaking through the first drain port and the outer peripheral wall of the first drain pipe, thereby improving the sealing performance.
[0030] In some embodiments of the present application, a third ring groove is provided on the side of the first limiting ring facing the second drain outlet, and the diameter of the third ring groove is smaller than that of the first ring groove; a blocking ring is provided on the first accommodating cavity, and the blocking ring is used to be inserted into the third ring groove.
[0031] In the technical solution, the blocking ring is accommodated by the third ring groove. When sewage passes through the first sealing ring, the sewage is blocked by the blocking ring, thereby further preventing sewage from leaking between the first drain port and the outer peripheral wall of the first drain pipe, and further improving the sealing performance.
[0032] In some embodiments of the present application, the bottom wall of the outer box is provided with a second accommodating cavity, and the second drain port is opened in the second accommodating cavity;
[0033] The second drain pipe passes through the second drain port, and a second limiting ring is provided on the outer peripheral wall of the bottom end of the second drain pipe; the second limiting ring is used to be arranged in the second accommodating cavity;

[0058] In this application, the refrigerator is composed of a refrigeration system, a control system, a box body and other parts. The refrigeration system is the core part of the refrigerator, which includes components such as a compressor, a condenser, and an evaporator, which can reduce the temperature inside the box to the required level and keep it constant. The control system is responsible for controlling the operation and temperature regulation of the refrigerator. The box body is the outer shell of the refrigerator, usually made of stainless steel, steel plate and other materials, which can effectively isolate the external temperature and moisture and maintain the internal low temperature environment.
[0059] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0060] Please refer to all the drawings. In an exemplary embodiment of the refrigerator of the utility model, the refrigerator includes: an outer box 200, an inner box 100, a first drain port 300, a second drain port 400, a first drain pipe 500 and a second drain pipe 120; wherein the top of the outer box 200 is open;
[0061] The inner box body 100 is disposed inside the outer box body 200 , and the top of the inner box body 100 is open and corresponds to the opening of the outer box body 200 .
[0062] The first drain port 300 penetrates the bottom wall of the inner box 100 .
[0063] The second drain port 400 passes through the bottom wall of the outer box body 200 .
[0064] The first drain pipe 500 is disposed between the bottom wall of the outer box 200 and the bottom wall of the inner box 100 , and the top end of the first drain pipe 500 is connected to the first drain port 300 .
[0065] The bottom end of the second drain pipe 120 is connected to the second drain port 400 ; the top end of the second drain pipe 120 is sleeved on the bottom end of the first drain pipe 500 .
[0066] Through the above scheme, the first drain pipe 500 and the second drain pipe 120 are slidably connected. Therefore, for different refrigerator models, when the distance between the bottom wall of the outer box body 200 and the bottom wall of the inner box body 100 is different, the first drain pipe 500 and the second drain pipe 120 slide to the corresponding distance accordingly, and can be adjusted according to different needs. It is suitable for various models of refrigerators and has a high degree of commonality.
[0067] During adjustment, the bottom end of the first drain pipe 500 slides inside the top end of the second drain pipe 120. Because the bottom end of the first drain pipe 500 is located inside the second drain pipe 120, there is no possibility of sewage leaking out of the second drain pipe 120, and it is prevented that sewage drips into the outer box 200.
[0068] In some embodiments, the first drain pipe 500 is a round pipe. The second drain pipe 120 is a round pipe.
[0069] In some embodiments, the first drain pipe 500 is coaxially disposed above the second drain pipe 120 .
[0070] In some embodiments, the bottom wall of the inner box 100 is parallel to the bottom wall of the outer box 200 .
[0071] In some embodiments, the first drain pipe 500 and the second drain pipe 120 are perpendicular to the bottom wall of the inner box 100 . Or the first drain pipe 500 and the second drain pipe 120 are perpendicular to the bottom wall of the outer box 200 .
[0072] In some embodiments, the outer diameter of the first drain pipe 500 is the same as the inner diameter of the second drain pipe 120, so as to improve the sealing between the first drain pipe 500 and the second drain pipe 120 and prevent sewage leakage.
[0073] In some embodiments, the outer diameter of the first drain pipe 500 is smaller than the inner diameter of the second drain pipe 120, and a first seal is provided between the first drain pipe 500 and the second drain pipe 120. The first seal increases the sealing between the first drain pipe 500 and the second drain pipe 120.
[0074] In some embodiments, the first sealing member is a sealing ring, which is sleeved on the bottom end of the first drain pipe 500, and the outer wall of the sealing ring abuts against the inner wall of the second drain pipe 120, so that the sealing between the first drain pipe 500 and the second drain pipe 120 is achieved through the sealing ring.
[0075] In some embodiments, the sealing ring is made of rubber material and has elasticity. When the sealing ring is disposed between the first drain pipe 500 and the second drain pipe 120 , it is slightly compressed, thereby further improving the sealing performance between the first drain pipe 500 and the second drain pipe 120 .
[0076] In some embodiments, the top end of the second drain pipe 120 is expanded toward the first drain pipe 500. During installation, the expansion is used for guidance, making it easier to insert the first drain pipe 500 into the second drain pipe 120, facilitating installation and improving installation efficiency.
[0077] In another embodiment, the inner diameter of the top end of the second drain pipe 120 gradually increases in a direction toward the inner box 100 .
[0078] In some embodiments, the inner bottom wall of the inner box body 100 is recessed toward the bottom wall of the outer box body 200 to form a first accommodating cavity 101 , and the first drain port 300 is opened in the first accommodating cavity 101 .
[0079] The first drain pipe 500 passes through the first drain port 300 , and a first limiting ring 600 is disposed on the outer peripheral wall of the top end of the first drain pipe 500 ; the first limiting ring 600 is used to be disposed in the first accommodating cavity 101 .
[0080] Through the above solution, the first drain pipe 500 is inserted from the inside of the inner box 100 , and the limiting ring falls into the first accommodating cavity 101 , thereby preventing the first drain pipe 500 from being separated from the inner box 100 .
[0081] The first accommodating cavity 101 is provided to accommodate a limiting ring, so as to prevent the limiting ring from protruding from the inner bottom wall of the inner box body 100 , thereby facilitating the placement of goods in the inner box body 100 .
[0082] In some embodiments, the first accommodating cavity 101 is formed by bending the bottom wall of the inner box body 100 downward.
[0083] In some embodiments, the first accommodating cavity 101 is formed by punching the bottom wall of the inner box body 100 .
[0084] In some embodiments, the first accommodating cavity 101 is in a disc shape. The first limiting ring 600 is in a circular ring shape and has a cross section. The axis of the first limiting ring 600 is located in the cross section. The cross section line of the first limiting ring 600 on the cross section is rectangular.
[0085] In some embodiments, the first limiting ring 600 is coaxially disposed at the top of the first drain pipe 500. The inner peripheral wall of the first limiting ring 600 is connected to the outer peripheral wall of the top of the first drain pipe 500.
[0086] In some embodiments, the first drain port 300 is a circular hole, and the first drain port 300 is coaxially opened on the inner bottom wall of the first accommodating cavity 101. When the first drain pipe 500 is coaxially plugged into the first drain port 300, the first limiting ring 600 is coaxially arranged in the first accommodating cavity 101 for easy arrangement.
[0087] In some embodiments, the first drain pipe 500 and the first limiting ring 600 are integrally formed to improve the strength of the structure.
[0088] In some embodiments, the inner peripheral wall of the first accommodating cavity 101 is inclined, and is inclined from bottom to top in a direction away from the first drain port 300. This design facilitates production and processing.
[0089] Please refer to all the drawings. In some embodiments, a first annular groove 700 is formed on a side of the first limiting ring 600 facing the second drain port 400 . A first sealing ring 800 is disposed in the first annular groove 700 .
[0090] The first sealing ring 800 is accommodated by the first annular groove 700, and the first sealing ring 800 seals the first limiting ring 600 and the inner bottom wall of the inner box body 100 to prevent sewage from leaking through the first drain port 300 and the outer peripheral wall of the first drain pipe 500, thereby improving the sealing performance.
[0091] In some embodiments, the first annular groove 700 is coaxially opened on the bottom wall of the first limiting ring 600, and the first sealing ring 800 is coaxially sleeved on the first drain pipe 500. When the first limiting ring 600 is installed in the first accommodating chamber 101, the first sealing ring 800 is located in the first annular groove 700, and the top wall of the first sealing ring 800 abuts against the inner top wall of the first annular groove 700, and the bottom wall of the first sealing ring 800 abuts against the inner bottom wall of the first accommodating chamber 101. In this way, sewage is prevented from entering between the first sealing ring 800 and the first drain pipe 500.
[0092] Please refer to all the drawings. In some embodiments, a third annular groove 900 is provided on the side of the first limiting ring 600 facing the second drain outlet 400. The diameter of the third annular groove 900 is smaller than that of the first annular groove 700. A blocking ring 110 is provided on the first accommodating cavity 101. The blocking ring 110 is used to be inserted into the third annular groove 900.
[0093] The blocking ring 110 is accommodated by the third annular groove 900. When sewage passes through the first sealing ring 800, the sewage is blocked by the blocking ring 110, thereby further preventing sewage from leaking between the first drain port 300 and the outer peripheral wall of the first drain pipe 500, and further improving the sealing performance.
[0094] Furthermore, when manufacturing a refrigerator, foam material needs to be placed between the inner box 100 and the outer box 200 to form a foam layer with a heat-insulating effect. During the foaming process, part of the foam material will move toward the first drain port 300. If the foam material wants to enter the inner box 100, it must first pass through the blocking ring 110 and the third annular groove 900 and then bend downward to the upper surface of the first accommodating cavity 101. However, the characteristics of the foam material are not enough to pass through the blocking ring 110 and the third annular groove 900. This prevents the foam material from entering the inner box 100.
[0095] If the third annular groove 900 and the blocking ring 110 are not provided, the foam material will directly enter between the first accommodating cavity 101 and the first limiting ring 600 through the first drain port 300 .
[0096] In some embodiments, the inner circumferential wall of the third annular groove 900 is flush with the outer circumferential wall of the first drain pipe 500 to facilitate production.
[0097] In another embodiment, the diameter of the inner circumferential wall of the third annular groove 900 is the same as the outer diameter of the first drain pipe 500 .
[0098] In some embodiments, the inner circumferential wall of the blocking ring 110 is flush with the inner circumferential wall of the first drain port 300 .
[0099] In some embodiments, the inner diameter of the blocking ring 110 is the same as the inner diameter of the first drain port 300 .
[0100] Please refer to all the drawings. In some embodiments, the bottom wall of the outer box 200 is provided with a second accommodating cavity 201 , and the second drain port 400 is opened in the second accommodating cavity 201 ;
[0101] The second drain pipe 120 passes through the second drain port 400 , and a second limiting ring 130 is disposed on the outer peripheral wall of the bottom end of the second drain pipe 120 ; the second limiting ring 130 is used to be disposed in the second accommodation cavity 201 ;
[0102] A limiting member 170 is provided in the second accommodation cavity 201, and the limiting member 170 is used to fix the second drain pipe 120. The second drain pipe 120 is inserted from the bottom of the outer box 200, the second limiting ring 130 is inserted into the second container, and the limiting member 170 is connected to the second accommodation cavity 201, so that the position of the second limiting ring 130 can be fixed, thereby achieving the fixation of the second drain pipe 120.
[0103] In some embodiments, the second accommodating cavity 201 is recessed toward the top of the box body.
[0104] In some embodiments, the second accommodating cavity 201 is cylindrical in shape. The second drain port 400 is a circular hole, and the second drain port 400 is coaxially opened on the inner top wall of the second accommodating cavity 201 .
[0105] The second limiting ring 130 is coaxially arranged at the bottom end of the second drain pipe 120 . When the second drain pipe 120 is coaxially inserted into the second drain port 400 , the second limiting ring 130 is also coaxially located in the second accommodating cavity 201 , which is convenient for installation.
[0106] In some embodiments, the aperture of the second drain port 400 is larger than the maximum outer diameter of the second drain pipe 120 , so as to facilitate the expansion of the second drain pipe 120 .
[0107] In some embodiments, a second annular groove 140 is formed on the second accommodating cavity 201 , a second sealing ring 150 is disposed in the second annular groove 140 , and the second sealing ring 150 is located on a side of the second limiting ring 130 facing the inner box body 100 .
[0108] The second sealing ring 150 is accommodated by the second annular groove 140 , and the second sealing ring 150 seals the outer bottom wall of the outer box body 200 and the second limiting ring 130 , thereby improving the sealing performance between the second sealing ring 150 and the outer box body 200 .
[0109] Because foam material needs to be placed between the outer box body 200 and the inner box body 100 to form a temperature insulation layer, this arrangement can prevent the foam material from leaking through the second limiting ring 130 and the box body when the foam material is being made.
[0110] Please refer to all the drawings. In some embodiments, the second annular groove 140 is coaxially opened on the inner top wall of the second accommodating cavity 201. The second sealing ring 150 is sleeved on the second drain pipe 120. When the second drain pipe 120 is fixed by the stopper 170, the second sealing ring 150 is located in the second annular groove 140, the upper surface of the second sealing ring 150 abuts against the inner top wall of the second accommodating cavity 201, and the lower surface of the second sealing ring 150 abuts against the upper surface of the second stop ring 130.
[0111] In some embodiments, the inner circumferential wall of the second sealing ring 150 is inclined, and is inclined from top to bottom toward the axis of the second sealing ring 150. When foam material is placed between the outer box 200 and the inner box 100, the foam material will enter the upper part of the second limiting ring 130 through the second drain port 400. The foam material will contact the inclined inner circumferential wall of the second sealing ring 150, and under the squeezing force of the foam material, the second sealing ring 150 will be close to the second limiting ring 130, further improving the sealing effect and preventing the foam material from overflowing through the gap between the second sealing ring 150 and the second accommodating cavity 201.
[0112] In another embodiment, the diameter of the inner circumferential wall of the second sealing ring 150 gradually decreases in a direction away from the first drain pipe 500 .
[0113] In some embodiments, the stopper 170 is threadedly connected to the second accommodating cavity 201, and a third drain port for communicating with the second drain pipe 120 is provided on the stopper 170. When the stopper 170 is tightened to the second accommodating cavity 201, the stopper 170 moves toward the inner box 100 until the stopper 170 and the bottom wall of the second accommodating cavity 201 clamp the second sealing ring 150 and the stopper 170, which has a simple structure and is easy to install.
[0114] In some embodiments, the limiting member 170 may be tubular, and the outer peripheral wall of the limiting member 170 may be provided with a first thread segment.
[0115] The inner peripheral wall of the second accommodating cavity 201 may be provided with a second thread segment. The first thread segment of the stopper 170 is connected to the second thread segment of the second accommodating cavity 201 to achieve the connection between the stopper 170 and the accommodating cavity.
[0116] When the limiting member 170 is coaxially threadedly connected to the second accommodating cavity 201 , the limiting member 170 is rotated and moves along its axial direction to clamp or loosen the second limiting ring 130 .
[0117] In some embodiments, a connection port is provided at the bottom of the outer box 200, a connection member 160 is detachably connected to the connection port, and the receiving cavity is provided in the connection member 160. The connection member 160 can be removed or installed together with the second drain pipe 120, the stopper 170 and the second sealing ring 150.
[0118] In some embodiments, the connection port may be a circular hole. The connection member 160 may be a cylinder. The accommodating cavity is a cylindrical chamber and is coaxially opened at one end of the connection member 160 away from the inner box 100 .
[0119] In addition, the present application also provides a refrigerator, which includes: an outer box body 200, an inner box body 100, a first drain port 300, a second drain port 400, a first drain pipe 500 and a second drain pipe 120, wherein the top of the outer box body 200 is open.
[0120] The inner box body 100 is disposed inside the outer box body 200 , and the top of the inner box body 100 is open and corresponds to the opening of the outer box body 200 .
[0121] The first drain port 300 penetrates the bottom wall of the inner box 100 .
[0122] The second drain port 400 passes through the bottom wall of the outer box body 200 .
[0123] The first drain pipe 500 is disposed between the bottom wall of the outer box 200 and the bottom wall of the inner box 100 , and the top end of the first drain pipe 500 is connected to the first drain port 300 .
[0124] The bottom end of the second drain pipe 120 is connected to the second drain port 400; the top end of the second drain pipe 120 is plugged into the bottom end of the first drain pipe 500. The second drain pipe 120 and the first drain pipe 500 can slide against each other; the outer peripheral wall of the second drain pipe 120 is sealed with the inner peripheral wall of the first drain pipe 500.
[0125] Through the above scheme, the first drain pipe 500 and the second drain pipe 120 are slidably connected. Therefore, for different refrigerator models, when the distance between the bottom wall of the outer box body 200 and the bottom wall of the inner box body 100 is different, the first drain pipe 500 and the second drain pipe 120 slide to the corresponding distance accordingly, and can be adjusted according to different needs. It is suitable for various models of refrigerators and has a high degree of commonality.
[0126] During adjustment, the top end of the second drain pipe 120 slides inside the bottom end of the first drain pipe 500. Since the outer peripheral wall of the second drain pipe 120 is sealed with the inner peripheral wall of the first drain pipe 500, the possibility of sewage leaking out of the second drain pipe 120 is avoided, and sewage is prevented from dripping into the outer box body 200.
[0127] In some embodiments, the first drain pipe 500 is a round pipe. The second drain pipe 120 is a round pipe.
[0128] In some embodiments, the first drain pipe 500 is coaxially disposed above the second drain pipe 120 .
[0129] In some embodiments, the bottom wall of the inner box 100 is parallel to the bottom wall of the outer box 200 .
[0130] In some embodiments, the first drain pipe 500 and the second drain pipe 120 are perpendicular to the bottom wall of the inner box 100 . Or the first drain pipe 500 and the second drain pipe 120 are perpendicular to the bottom wall of the outer box 200 .
[0131] In some embodiments, the inner diameter of the first drain pipe 500 is the same as the outer diameter of the second drain pipe 120, so as to improve the sealing between the first drain pipe 500 and the second drain pipe 120 and prevent sewage leakage.
[0132] In some embodiments, the inner diameter of the first drain pipe 500 is smaller than the outer diameter of the second drain pipe 120, and a second seal is disposed between the first drain pipe 500 and the second drain pipe 120. The second seal increases the sealing between the first drain pipe 500 and the second drain pipe 120.
[0133] In some embodiments, the second sealing member is a sealing ring, which is sleeved on the top of the second drain pipe 120, and the outer wall of the sealing ring abuts against the inner wall of the first drain pipe 500, so that the sealing between the first drain pipe 500 and the second drain pipe 120 is achieved by the sealing ring.
[0134] In some embodiments, the sealing ring is made of rubber material and has elasticity. When the sealing ring is disposed between the first drain pipe 500 and the second drain pipe 120 , it is slightly compressed, thereby further improving the sealing performance between the first drain pipe 500 and the second drain pipe 120 .
[0135] In some embodiments, the bottom end of the first drain pipe 500 is expanded toward the second drain pipe 120. During installation, the expansion is used for guidance, making it easier to insert the second drain pipe 120 into the first drain pipe 500, facilitating installation and improving installation efficiency.
[0136] In another embodiment, the inner diameter of the bottom end of the first drain pipe 500 gradually increases in a direction toward the bottom wall of the outer box body 200 .
