[0059] In the following description, among the hinge members 140 and 150 , the lower hinge member 140 may be referred to as a first hinge member 140 , and the upper hinge member 150 may be referred to as a second hinge member 150 .

[0060] The housing 110 may form the appearance of the rotating lever 100 together with the housing cover 120 and the cover plate 130. The housing 110 may have an open side to accommodate hinge covers 145 and 155 and a guide cover 173 to be described below. The open side of the housing 110 may be covered by the housing cover 120 and the cover plate 130.

[0061] The housing 110 may include a blocking rib 111 formed by a portion of the upper surface of the housing 110 protruding upward at the front end.

For example, the housing 110 and the housing cover 120 may include acrylonitrile butadiene styrene copolymer (ABS) resin.

[0063] The cover plate 130 may be coupled to the housing cover 120. Unlike the housing 110 and the housing cover 120, the cover plate 130 may include a metal material. A heat generating member may be provided between the cover plate 130 and the housing cover 120. The heat generating member may prevent dew from forming on the cover plate 130 due to a temperature difference between the inside of the storage chamber 21 and the outside of the storage chamber 21.

[0064] The guide protrusion 170 may be configured to be inserted into a rotation guide 200 provided on the body 10. The guide protrusion 170 may be guided by the rotation guide 200 during rotation of the door 30 coupled with the rotation lever 100.

[0065] The housing 110 may include a guide opening 112 formed to open in a portion of an upper surface of the housing 110. The guide protrusion 170 may protrude upward from the upper surface of the housing 110 by passing through the guide opening 112. The guide protrusion 170 may be introduced into the interior of the housing 110 by passing through the guide opening 112.

[0066] The guide protrusion 170 may protrude upward from the upper surface of the housing 110 by the elastic force of the elastic member 171. When a force greater than or equal to the elastic force of the elastic member 171 is applied downward to the guide protrusion 170, the guide protrusion 170 may be introduced into the housing 110.

[0067] In the process of the door 30 being opened or closed, the guide protrusion 170 may be guided by the rotating guide 200 and thereby introduced into the interior of the housing 110 or protruded from the interior of the housing 110 to the exterior of the housing 110. For example, in the process of the door 30 being closed, the guide protrusion 170 protruding outward from the housing 110 may be inserted into the guide groove 201 of the rotating guide 200. When the door 30 is being closed, the guide protrusion 170 may be gradually introduced into the interior of the housing 110 while moving along the guide groove 201. When the door 30 is completely closed, the guide protrusion 170 may protrude to the exterior of the housing 110.

[0068] Alternatively, the guide protrusion may be arranged not to be introduced into the interior of the housing. In other words, the guide protrusion may be arranged to remain protruding outside the housing. In this case, the elastic member and the guide accommodating portion for accommodating the elastic member and the guide protrusion may not be provided. In addition, the guide protrusion may be provided on the main body, and the rotation guide may be provided on the rotating rod. Specifically, the guide groove may be provided on the upper surface of the rotating rod, and the main body may be provided with a guide protrusion formed to be inserted into the guide groove.

[0069] When the side of the rotating rod 100 on which the cover plate 130 and the housing cover 120 are arranged is referred to as the front side of the rotating rod 100 for ease of description, a buffer member 180 may be formed on the rear side of the rotating rod 100. The buffer member 180 may protrude backward from the rear surface of the rotating rod 100. When the rotating rod 100 contacts the door 30, the buffer member 180 may reduce the noise and impact caused by the contact or collision between the rotating rod 100 and the door 30. The buffer member 180 may be formed of a material capable of absorbing impact and noise. The buffer member 180 may include an upper buffer member 181, an intermediate buffer member 182, and a lower buffer member 183. However, the present disclosure is not limited thereto, and the arrangement or number of the buffer members may be changed.

[0087] Figure 6 It is shown in Figure 3 A view of the interior of the lower portion of the rotating rod is shown in FIG. Figure 7 is Figure 6 Exploded view of the rotating rod shown in .

[0088] According to an embodiment, after assembling the rotating rod 100, the foaming liquid forming the insulation member 190 may be foamed inside the rotating rod 100. In other words, after pre-assembly of the rotating rod 100, the foaming liquid may be injected into the rotating rod 100 through the injection hole 113 to form the insulation member.

[0089] According to an embodiment, the rotating rod 100 can be assembled only by elastic coupling or assembly coupling without using a separate fastening member. In addition, the rotating rod 100 can be pre-assembled, and then the foaming liquid can be injected into the rotating rod 100 and solidified to form the heat insulation member 190. The foaming liquid injected into the rotating rod 100 can not only form the heat insulation member 190, but also can be used as an adhesive to prevent the rotating rod 100 assembled without the fastening member from separating. Through this construction, the types and quantities of parts required when manufacturing the rotating rod and the number of assembly processes can be reduced. In addition, since the time and cost required for manufacturing the rotating rod can also be reduced, productivity can be improved.

[0090] refer to Figure 6 and Figure 7 , when the foaming liquid is injected into the rotating rod 100, the rotating rod 100 can prevent the foaming liquid from being introduced into the first hinge accommodating portion 114a in which the first hinge member 140 is accommodated.

[0091] The heat insulating space 110a formed inside the housing 110 may have a foaming liquid injected through an injection hole 113 formed on the lower surface of the housing 110. Since the foaming liquid hardens to form the heat insulating member 190, if the foaming liquid flows into the first hinge accommodating portion 114a in which the first hinge member 140 is accommodated, the first hinge member 140 may not rotate normally. Therefore, it is necessary to block the foaming liquid from flowing into the first hinge accommodating portion 114a.

[0092] refer to Figure 7 , the housing 110 may include a first hinge partition wall 114, which forms the outer edge of the first hinge accommodating portion 114a and serves as a partition wall for blocking the inflow of foaming liquid. The first hinge partition wall 114 may form the first hinge accommodating portion 114a on its inner side. The first hinge accommodating portion 114a may be arranged in the form of a side with an opening. The first hinge cover 145 may be coupled to the first hinge partition wall 114 to cover the open side of the first hinge accommodating portion 114a. The first hinge cover 145 and the first hinge partition wall 114 may have corresponding shapes. Through such a structure, the first hinge partition wall 114 is arranged on the inner side of the first hinge cover 145, so that the first hinge cover 145 and the first hinge partition wall 114 can be assembled and coupled to each other.

[0093] When the first hinge cover 145 is coupled to the first hinge partition wall 114 , the foaming liquid may be blocked from flowing into the first hinge accommodating portion 114 a formed inside the first hinge cover 145 and the first hinge partition wall 114 .

[0094] refer to Figure 7 The housing 110 may include a supporting protrusion 114b and a first fixing protrusion 114c and a second fixing protrusion 114d, wherein the supporting protrusion 114b is inserted into the first hinge member 140 and supports the first hinge member 140 in a rotatable manner, and the first fixing protrusion 114c and the second fixing protrusion 114d are arranged to form a connecting space 114e and elastically support the first hinge member 140, which is inserted into the connecting space 114e.

[0095] The first hinge member 140 may include a door coupling portion 141 configured to be coupled to the door 30, an axis portion 142 coupled to the first hinge accommodating portion 114a and serving as a rotation axis of the first hinge member 140, and a connecting portion 143 connecting the door coupling portion 141 and the axis portion 142. The axis portion 142 may be provided with an axis hole 144 on the lower portion, into which the support protrusion 114b is inserted. Alternatively, the axis portion may be provided with a support protrusion on the lower portion, and the housing may be provided with an axis hole into which the support protrusion may be inserted. In other words, the positions of the axis hole of the axis portion and the support protrusion of the housing may be interchanged.

[0096] refer to Figure 7 , a predetermined gap may be provided between the first fixing protrusion 114c and the second fixing protrusion 114d. The distance between the first fixing protrusion 114c and the second fixing protrusion 114d forming the predetermined gap is represented as l. The diameter of the shaft portion 142 at a point passing through the predetermined gap is represented as L. The diameter L of the shaft portion 42 at this point may be greater than the distance l between the first fixing protrusion 114c and the second fixing protrusion 114d forming the predetermined gap.

[0098] refer to Figure 8 and Fig. 9 , the first hinge member 140 may be coupled to the inside of the first hinge accommodating portion 114a without a separate fastening member.

[0099] The first hinge member 140 can be coupled to the inside of the first hinge accommodating portion 114a by positioning the first hinge member 140 so that the support protrusion 114b is inserted into the shaft hole 144 of the shaft portion 142, and then by rotating the shaft portion 142 so that the shaft portion 142 passes through the gap between the first fixing protrusion 114c and the second fixing protrusion 114d and is inserted into the coupling space 114e. The shaft portion 142 can be inserted into the coupling space 114e by passing through the gap between the first fixing protrusion 114c and the second fixing protrusion 114d. As described above, since the diameter L of the shaft portion 142 at one point is greater than the distance l between the first fixing protrusion 114c and the second fixing protrusion 114d forming the predetermined gap, the first fixing protrusion 114c and the second fixing protrusion 114d can be elastically deformed so that the shaft portion 142 passes through the gap between the first fixing protrusion 114c and the second fixing protrusion 114d. The shaft portion 142 inserted into the coupling space 114e by passing through the gap between the first and second fixing protrusions 114c and 114d may be fixed by the first and second fixing protrusions 114c and 114d and thereby prevented from being separated from the coupling space 114e.

[0102] refer to Fig.10 , the wire cover member 160 may be coupled to the middle portion of the housing 110. The housing 110 may be provided in its middle portion with a cover member fixing portion 117 and a first wire hole 117a formed by an opening in an upper surface of the cover member fixing portion 117. The wires may extend from the inside of the housing 110 through the first wire hole 117a to the wire cover member 160. The plurality of ribs extending in the up-down direction shown in the middle portion of the housing 110 are reinforcement ribs 118, which are provided to reinforce the strength of the housing 110.

[0103] The wire cover member 160 may include: a door coupling portion 161 configured to be coupled to the door 30; a second wire hole 161a formed to pass through the door coupling portion 161 and configured to allow the wires to be taken out through the second wire hole 161a; and a rotating portion 162 serving as a rotating shaft of the wire cover member 160. The rotating portion 162 may include a third wire hole 162a passing through the rotating portion 162 in a direction along which the rotating axis of the rotating portion 162 extends. The rotating portion 162 may be inserted into a cover member accommodating space 117b provided on the rear surface of the housing 110.

[0104] Fig.12 The wire cover member is connected to the Fig.11 A view of the process of the case shown. Fig.13 The wire cover member is connected to the Fig.11 A view of the state of the housing shown in FIG.

[0105] refer to Fig.12 and Fig.13 , the wire cover member 160 can be coupled to the housing 110 without a separate fastening member. The wire cover member 160 can be coupled to the housing 110 by being inserted into the cover member accommodating space 117b provided on the rear surface of the housing 110. The wire cover member 160 can be coupled to the housing 110 without a separate fastening member by inserting the rotating portion 162 into the cover member accommodating space 117b so that the rotating portion 162 is inserted into the first wire hole 117a. In a state where the wire cover member 160 is coupled to the housing 110, the upper portion of the rotating portion 162 can be placed in the first wire hole 117a. The lower portion of the rotating portion 162 can be placed in the cover member accommodating space 117b. The wires inside the housing 110 can be led out to the second wire hole 161a through the third wire hole 162a located inside the first wire hole 117a.

[0106] Fig.14 It is shown in Figure 3 A view of the interior of the upper portion of the rotating rod is shown in FIG. Fig.15 It is shown in Fig.14 Exploded view of the rotating rod shown in .

[0107] refer to Fig.14 and Fig.15, the second hinge member 150 can be coupled to the second hinge accommodating portion 115a formed inside the second hinge partition wall 115 without a separate fastening member. Similar to the first hinge member 140, the second hinge member 150 may include a door coupling portion 151, an axis portion 152, an axis hole 154, and a connecting portion 153. Since the method and structure for coupling the second hinge member 150 to the second hinge accommodating portion 115a are the same as the method and structure for coupling the first hinge member 140 to the first hinge accommodating portion 114a, further description is omitted. In the second hinge cover 155, a cover rib 156 provided in a shape corresponding to the second hinge partition wall 115 is arranged to surround the second hinge partition wall 115, and the second hinge cover 155 can be assembled and coupled to the second hinge partition wall 115. Because the second hinge cover 155 is coupled to the second hinge partition wall 115, it is possible to block the foaming liquid from flowing into the second hinge accommodating portion 115a.

[0108] The housing 110 may include a guide accommodating portion 116a configured to accommodate the guide protrusion 170 and the elastic member 171. The guide accommodating portion 116a may be formed on the inner side of the guide partition wall 116. The guide cover 173 may be configured to cover the open side of the guide accommodating portion 116a. The guide cover 173 may include a first rib 174 corresponding to the shape of the guide partition wall 116. When the first rib 174 is inserted into the outer side of the guide partition wall 116, the guide cover 173 may be connected to the guide partition wall 116 without a separate fastening member. When the guide cover 173 is connected to the guide partition wall 116, the foaming liquid can be blocked from flowing into the guide accommodating portion 116a. The detailed structure is described below.

[0109] In the guide receiving portion 116a formed inside the guide cover 173 and the guide partition wall 116, the guide protrusion 170 and the elastic member 171 may be arranged. The elastic member 171 may provide elastic force to the guide protrusion 170 so that the guide protrusion 170 protrudes upward from the upper surface of the housing 110 by passing through the guide opening 112 of the housing 110.

[0110] The guide cover 173 may further include a second rib 175 and a coupling groove ( Figure 5 and Fig.19 176 in the figure), the second rib 175 is arranged to be parallel to the first rib 174, and the coupling groove is formed between the first rib 174 and the second rib 175. The second rib 175 and the coupling groove 176 are described below.

[0111] Fig.16 It is along Figure 3 A cross-sectional view taken along line AA'.

[0112] According to an embodiment, the housing 110 and the housing cover 120 may be attached to each other by a foaming liquid. The housing 110 and the housing cover 120 may be connected to each other by a protrusion and groove structure described below in the case of a separate tool or fastening member. The housing 110 and the housing cover 120 may be assembled by a protrusion and groove structure, but the housing 110 and the housing cover 120 may be separable. In a state where the housing 110 and the housing cover 120 are assembled, the foaming liquid may be injected into the insulating space 110a as the inner space between the housing 110 and the housing cover 120, and then solidified, and thus the insulating member 190 may be formed in the insulating space 110a. The foaming liquid injected into the insulating space 110a may be used as an adhesive so that the housing 110 and the housing cover 120 will not separate from each other. Therefore, after the insulating member 190 is formed, the housing 110 and the housing cover 120, which are connected to each other by the insulating member 190, may be prevented from separating from each other.

[0113] based on Fig.16 , one side 100a and the other side 100b of the rotating rod 100 may be defined. When the rotating rod 100 is in the first position where the rotating rod 100 is substantially perpendicular to the door 30, the one side 100a of the rotating rod 100 may be arranged to face the outside of the storage chamber 21, and the other side 100b of the rotating rod 100 may be arranged to face the inside of the storage chamber 21. Due to this arrangement, when the door 30 is opened, the one side 100a of the rotating rod 100 may be located in the visible area of ​​the user, while the other side 100b of the rotating rod 100 may not be located in the visible area of ​​the user.

[0114] According to an embodiment, on one side 100a of the rotating rod 100, the housing 110 and the housing cover 120 can be prevented from being separated from each other due to the foaming stress of the foaming liquid. To this end, the housing or the housing cover may include an insertion protrusion, and the housing cover or the housing may include an insertion groove into which the insertion protrusion is inserted. For example, Fig.16 As shown, the housing cover 120 may include an insertion protrusion 120a, and the housing 110 may include an insertion groove 110d into which the insertion protrusion 120a may be inserted. The insertion groove 110d may be formed between the first protrusion 110b and the second protrusion 110c provided on one side of the housing 110.

[0115] When the insertion protrusion 120a is inserted into the insertion groove 110d, the insertion protrusion 120a can be constrained by the first protrusion 110b and the second protrusion 110c. Since the insertion protrusion 120a is constrained by the first protrusion 110b and the second protrusion 110c, even when the foaming stress of the foaming liquid is applied, the insertion protrusion 120a can be prevented from being removed from the insertion groove 110d. Through this configuration, the housing 110 and the housing cover 120 can be prevented from being spaced apart from each other and a gap can be prevented from being formed on one side 100a of the rotating rod 100. Since there is no gap on the side 100a of the rotating rod 100 exposed to the user, the finishing reliability of the product can be improved.

[0116] A pair of protrusion structures may be provided on the other side 100b of the rotating rod 100. For example, the housing 110 may include a third protrusion 110e protruding toward the housing cover 120, and the housing cover 120 may include a fourth protrusion 120b configured to engage with the third protrusion 110e. However, the present disclosure is not limited thereto, and similar to the one side 100a of the rotating rod, a protrusion and groove structure may be provided on the other side 100b of the rotating rod.

[0117] Fig.17 It is along Figure 3 A cross-sectional view taken along line BB'.

[0118] refer to Fig.17 , the first hinge cover 145 includes a first cover protrusion 146, a second cover protrusion 147, and a cover groove 148 formed between the first cover protrusion 146 and the second cover protrusion 147. The first hinge partition wall 114 can be inserted into the cover groove 148. Through this structure, the foaming liquid in the insulation space 110a can be blocked from flowing into the interior of the first hinge accommodating portion 114a from the insulation space 110a. The foaming liquid needs to pass through all of the first cover protrusion 146, the first hinge partition wall 114, and the second cover protrusion 147 to make the foaming liquid flow into the first hinge accommodating portion 114a. Since the inflow path of the foaming liquid into the first hinge accommodating portion 114a is complicated, the foaming liquid can be blocked from flowing into the first hinge accommodating portion 114a through the first cover protrusion 146, the first hinge partition wall 114, and the second cover protrusion 147.

[0119] refer to Fig.17, the first hinge cover 145 may include an inclined surface 149 that extends obliquely from one end of the first cover protrusion 146 toward the first hinge member 140. The inclined surface 149 may be arranged so that the distance between the inclined surface 149 and the housing cover 120 decreases in the direction from the first cover protrusion 146 to the first hinge member 140. The inclined surface 149 may guide the foaming liquid so that the foaming liquid is uniformly filled inside the insulation space 110a. By moving the foaming liquid along the inclined surface 149, the foaming liquid may uniformly fill the narrow space between the inclined surface 149 and the housing cover 120.

[0120] Fig.18 It is along Figure 3 A cross-sectional view taken along line CC'.

[0121] refer to Fig.18 , bending of the rotating lever 100 due to a difference in linear expansion coefficient between the cover plate 130 formed of a metal material and the case cover 120 formed by injection molding or formed of a resin material may be prevented.

[0122] As described above, in the rotating rod 100 according to the embodiment, components may be pre-assembled, and a high-temperature foaming liquid may be injected through the injection hole 113 and then cured to form the heat insulating member 190 inside the rotating rod 100 .

[0123] When the high-temperature foaming liquid is foamed inside the rotating rod 100, the cover plate 130 formed by the metal material can expand more than the housing cover 120 formed by injection molding or formed by the resin material. On the contrary, when the rotating rod 100 is arranged inside the storage chamber 21 with a low temperature, the cover plate 130 can shrink more than the housing cover 120. This is because the linear expansion coefficient of the cover plate 130 formed by the metal material is greater than the linear expansion coefficient of the housing cover 120 formed by injection molding or formed by the resin material. Due to the difference in linear expansion coefficients, the rotating rod 100 may bend. For example, when the foaming liquid is injected, the cover plate 130 may expand more than the housing cover 120, and therefore the rotating rod 100 may bend. When the rotating rod 100 is placed inside the storage chamber 21 after the foaming liquid solidifies, the cover plate 130 may shrink more than the housing cover 120, and therefore the rotating rod 100 may bend.

[0124] In order to prevent bending of the rotating lever 100, the cover plate 130 may include a first protrusion accommodating portion 131 and a first protrusion accommodating hole 132 formed to pass through the first protrusion accommodating portion 131. The housing cover 120 may include a first coupling protrusion 122 disposed to be inserted into the first protrusion accommodating hole 132 and support ribs 124 extending on both sides of the first coupling protrusion 122.

[0125] In order to prevent the rotating rod 100 from bending due to the difference in linear expansion coefficient between the cover plate 130 and the housing cover 120, the first protrusion receiving hole 132 may be set to be larger than the first coupling protrusion 122, and the support rib 124 may be set to be spaced apart from both side ends of the first protrusion receiving portion 131 by a predetermined distance. Specifically, a predetermined gap g1 may be formed between one side end of the first protrusion receiving portion 131 and the support rib 124 adjacent to the one side end. Similarly, a predetermined gap g1 may be formed between the other side end of the first protrusion receiving portion 131 and the support rib 124 adjacent to the other side end. In addition, a predetermined gap g2 may be formed from one side end of the first coupling protrusion 122 inserted into the first protrusion receiving hole 132 to one side end of the first protrusion receiving hole 132. A predetermined gap g2 may be formed from the other side end of the first coupling protrusion 122 inserted into the first protrusion receiving hole 132 to the other end of the first protrusion receiving hole 132. Due to this structure, even when the cover plate 130 having a larger linear expansion coefficient expands or contracts more than the shell cover 120, the first connecting protrusion 122 can be located in the first protrusion accommodating hole 132, and the first protrusion accommodating portion 131 can neither contact the support rib 124 nor physically deform the support rib 124.

[0126] Fig.19 It is along Figure 3 A cross-sectional view taken along line D-D'.

[0127] refer to Fig.19 , it is possible to block the foaming liquid from flowing into the guide accommodating portion 116a formed inside the guide partition wall 116. The first rib 174 of the guide cover 173 may be arranged outside the guide partition wall 116. The first rib 174 may be inserted into a groove formed between the guide partition wall 116 and a predetermined protrusion provided outside the guide partition wall 116. As described above, such a protrusion and groove structure may block the inflow of the foaming liquid, and thereby prevent the foaming liquid from flowing into the guide accommodating portion 116a by passing through the first rib 174 and the guide partition wall 116.

[0128] The guide cover 173 may further include a second rib 175 and a coupling groove 176, the second rib 175 being arranged to be spaced outwardly from the first rib 174 by a predetermined distance, the coupling groove 176 being formed between the first rib 174 and the second rib 175. The fifth protrusion 120c of the housing cover 120 may be inserted into the coupling groove 176. The second rib 175, the fifth protrusion 120c and the first rib 174 may form the above-mentioned protrusion and groove structure. Therefore, the foaming liquid may be blocked from flowing into the guide accommodating portion 116a via the second rib 175, the fifth protrusion 120c and the first rib 174.

[0129] Fig. 20 It is along Figure 3 A cross-sectional view taken along line EE'.

[0130] refer to Fig. 20 , a plurality of partition walls and a plurality of grooves may be provided at the upper end of the rotating rod 100 to prevent leakage of the foaming liquid.

[0131] As described above, the injection hole 113 may be provided on the lower surface of the rotating rod 100. When the foaming liquid is injected into the injection hole 113, the rotating rod 100 may be arranged so that the injection hole 113 faces upward. When the foaming liquid is injected into the injection hole 113 by arranging the rotating rod 100 in an upside-down manner, the foaming liquid may flow in the gravity direction due to gravity. The foaming liquid may flow in the gravity direction and fill the heat insulating space 110a.

[0132] To prevent leakage of foaming liquid, such as Fig. 20 As shown, a plurality of partition walls and a plurality of grooves may be provided.

[0133] For example, the housing 110 may include a partition wall groove 116b into which the blocking partition wall 178 of the guide cover 173 is inserted. When the blocking partition wall 178 is inserted into the partition wall groove 116b, the blocking partition wall 178 and the partition wall groove 116b may prevent the foaming liquid from leaking through the blocking partition wall 178 and the partition wall groove 116b.

[0134] Similarly, the guide cover 173 may include a plurality of partition walls, and the housing cover 120 may also include a plurality of partition walls, thereby preventing the foaming liquid from leaking between the guide cover 173 and the housing cover 120 .

[0135] For example, the guide cover 173 may include a first blocking partition wall 177 a , a second blocking partition wall 177 b , a third blocking partition wall 177 c , a fourth blocking partition wall 177 d , and a fifth blocking partition wall 177 e which are successively formed in a vertical direction.

[0136] The shell cover 120 may include: a sixth blocking partition wall 125a inserted between the first blocking partition wall 177a and the second blocking partition wall 177b, a seventh blocking partition wall 125b inserted between the second blocking partition wall 177b and the third blocking partition wall 177c, an eighth blocking partition wall 125c inserted between the third blocking partition wall 177c and the fourth blocking partition wall 177d, and a ninth blocking partition arm 125d inserted between the fourth blocking partition wall 177d and the fifth blocking partition wall 177e.

[0137] Since the first to ninth blocking partition walls 177a, 177b, 177c, 177d, 177e, 125a, 125b, 125c and 125d complicate the movement path of the foaming liquid, leakage of the foaming liquid can be prevented.

[0139] refer to Fig.21 In the refrigerator according to the embodiment, the housing cover 220 may be formed integrally with the guide cover 273, the first hinge cover 245, and the second hinge cover 255. Since the housing cover 220 is formed integrally with the guide cover 273, the first hinge cover 245, and the second hinge cover 255, the assembly process of the rotating rod can be simplified, and the number of parts of the rotating rod can be reduced.
