[0021] In some embodiments of the rapid defrosting module, the bottom surface of the first pull-out component is provided with a plurality of third support columns extending toward the defrosting chamber, and the defrosting chamber is disposed on the third support columns.

[0022] In some embodiments of the rapid defrosting module, the defrosting assembly further includes a chassis, an extension, a defrosting chamber, and a heating chamber.

The defrosting chamber has a first storage cavity, the heating chamber has a second storage cavity, and the heating chamber is fixed inside the chassis.

[0023] The extension has a first extension channel and a second extension channel.

[0024] In some embodiments of the rapid defrosting module, the defrosting chamber is provided with a second partition, which divides the first storage cavity into a second liquid injection space and a second placement space. The second liquid injection space receives the liquid matrix and is connected to the second storage cavity. The second placement space is used to place the substance to be defrosted.

[0026] In some embodiments of the rapid defrosting module, the chassis has an installation space, and the heating chamber and the air extraction assembly are both fixed within the installation space; along the extension direction of the first pull-out channel, the installation space is located at the end of the first pull-out channel away from the first pull-out component.

[0027] In some embodiments of the rapid defrosting module, the chassis is provided with an exhaust port for discharging the defrosting gas inside the first pull-out component; when the first pull-out component is inserted into the first pull-out channel, the exhaust port is located above the first pull-out component and is located in a corner of the first pull-out component away from the installation space.

[0034] According to the rapid defrosting module proposed in the above embodiments, after the substance to be defrosted is placed in the defrosting component, the air extraction component removes air from the defrosting component, creating a low-pressure state inside the defrosting component. Under this low-pressure state, the boiling point of the liquid matrix inside the defrosting component decreases. When the heating component heats the liquid matrix to its boiling point, the liquid matrix vaporizes into defrosting gas. The defrosting gas comes into contact with the substance to be defrosted and exchanges heat, thereby completing the defrosting process. This invention employs a combined structure of a defrosting component, an air extraction component, and a heating component. High-temperature steam is generated under low pressure to rapidly defrost the substance, solving the problems of long defrosting times, easy nutrient loss, and overheating or uneven heating during defrosting in existing technologies.

[0055] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0057] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0058] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0059] Please see Figures 1-14 This invention provides a rapid defrosting module 100, comprising a defrosting component 110, an air extraction component 120, and a heating component 130. The defrosting component 110 is used to hold the liquid matrix and the substance to be defrosted, the air extraction component 120 is used to extract air from the defrosting component 110, and the heating component 130 is used to heat the liquid matrix to generate defrosting gas, which then defrosts the substance to be defrosted.

[0060] According to the rapid defrosting module 100 proposed in the above embodiment, after the substance to be defrosted is placed in the defrosting component 110, the air extraction component 120 extracts the air from the defrosting component 110, making the interior of the defrosting component 110 a low-pressure state. Under this low-pressure state, the boiling point of the liquid matrix in the defrosting component 110 decreases. When the heating component 130 heats the liquid matrix until it reaches the boiling point of the liquid matrix, the liquid matrix vaporizes into defrosting gas. The defrosting gas comes into contact with the substance to be defrosted and exchanges heat, thereby completing the defrosting of the substance.

[0061] The present invention employs a combination structure of a thawing component 110, a vacuum component 120, and a heating component 130 to generate high-temperature steam under low pressure to rapidly thaw the substance to be thawed, thus solving the problems of long thawing time, easy loss of nutrients, and overheating or uneven heating during thawing in the prior art.

[0062] The liquid matrix mentioned in the above embodiments can be water or other solutions, and this embodiment does not limit it to a single solution.

[0063] In addition, the substance to be thawed can be meat, vegetables, fruit, or dishes.

[0064] In one embodiment, the defrosting assembly 110 has a first storage cavity 110a for storing the substance to be defrosted and a second storage cavity 110b for storing the liquid matrix. The first storage cavity 110a and the second storage cavity 110b are in communication. The air extraction assembly 120 is used to extract air from the first storage cavity 110a and / or the second storage cavity 110b.

[0065] Specifically, the first receiving cavity 110a is connected to the inner cavity of the suction assembly 120. When the suction assembly 120 extracts gas from the first receiving cavity 110a, the gas in the second receiving cavity 110b is also extracted because it is connected to the first receiving cavity 110a. Of course, the liquid level of the liquid matrix in the second receiving cavity 110b is lower than the height at the connection point between the second receiving cavity 110b and the first receiving cavity 110a. In this embodiment, by placing the substance to be thawed and the liquid matrix in two separate cavities, contamination of the liquid matrix by the substance to be thawed can be avoided, reducing the difficulty of cleaning.

[0066] like Figures 1-2 As shown, in one embodiment, the defrosting assembly 110 includes a chassis 112 having a first pull-out channel 112a and a first pull-out member 1-114 slidably disposed within the first pull-out channel 112a, with a first storage cavity 1-110a within the first pull-out member 1-114.

[0067] When placing the substance to be thawed, the user can pull out the first pull-out component 1-114, place the substance into the first storage cavity 1-110a, and then push the first pull-out component 1-114 into the first pull-out channel 112a. This will thaw the substance. The operation is relatively convenient using the technical solution of this embodiment.

[0068] Furthermore, the defrosting assembly 110 also includes a defrosting chamber 116 having a first storage cavity 110a and a heating chamber 118 having a second storage cavity 110b. The defrosting chamber 116 is detachably installed in the first pull-out member 114, and the heating chamber 118 is fixed in the chassis 112.

[0069] In this embodiment, when the first pull-out component 114 slides into the interior of the housing 112 along the first pull-out channel 112a, the defrosting chamber 116 abuts against the heating chamber 118, thus connecting the first storage cavity 110a and the second storage cavity 110b. When the first pull-out component 114 is pulled out of the first pull-out channel 112a, the defrosting chamber 116 leaves the heating chamber 118, and the first storage cavity 110a and the second storage cavity 110b are disconnected. This design is simple in structure and easy for users to operate.

[0070] This invention presents two technical solutions for the first pull-out component of the thawing compartment. Please refer to the following text for further details.

[0071] Please see Figures 3-6 This invention proposes a first technical solution where the thawing chamber 2-116 is built into the first pull-out member 2-114. In this embodiment, when the thawing chamber 2-116 is placed inside the first pull-out member 2-114, the bottom surface of the thawing chamber 2-116 and the inner wall of the first pull-out member 2-114 enclose a third storage cavity 2-114a, which communicates with the first storage cavity 2-110a. The third storage cavity 2-114a is used to introduce freezing gas.

[0072] Understandably, when thawing is not required, the thawing chamber 2-116 can be used as a preservation chamber to store substances. However, after thawing the substances, the first storage chamber 2-110a is filled with thawing gas, which is the high-temperature gas generated by the heating element 130. This high-temperature gas is not conducive to the storage of substances. At this time, freezing gas is introduced into the third storage chamber 2-114a. This freezing gas gradually displaces the high-temperature gas in both the third and first storage chambers 2-110a, thus returning the first storage chamber 2-110a to a low-temperature environment.

[0073] It is worth mentioning that, based on the characteristic that the freezing gas is heavier than the high-temperature gas, the upper and lower layer design of the first receiving cavity 2-110a and the third receiving cavity 2-114a in this embodiment not only facilitates the freezing gas to squeeze out the high-temperature gas, but also reduces the amount of high-temperature gas entering the third receiving cavity 2-114a during thawing, so that the liquid matrix formed by the liquefaction of the high-temperature gas during thawing remains in the first receiving cavity 2-110a. For subsequent cleaning, only the thawing chamber 2-116 needs to be removed for cleaning.

[0074] like Figure 6 As shown, in a specific embodiment, a limiting step 2-1142 is provided on the inner wall of the first pull-out member 2-114, and the thawing chamber 2-116 is supported on the limiting step 2-1142.

[0075] In this embodiment, when the thawing chamber 2-116 is placed on the limiting step 2-1142 on the inner wall of the first pull-out member 2-114, the bottom surface of the thawing chamber 2-116 abuts against the limiting step 2-1142, and the outer wall of the thawing chamber 2-116 abuts against the inner wall of the first pull-out member 2-114, or leaves only a small amount of space. This design can minimize the escape of the refrigerant gas input into the third storage cavity 2-114a from the gap between the thawing chamber 2-116 and the inner wall of the first pull-out member 2-114.

[0076] Furthermore, in this embodiment, the design of the limiting step 2-1142 supporting the thawing chamber 2-116 allows the constraint of the thawing chamber 2-116 to be completed by utilizing the contour features of the first pull-out member 2-114, without the need to add an additional supporting structure, which makes the structure of the chassis 112 more compact.

[0077] Preferably, the limiting step 2-1142 is annular.

[0078] Please continue reading. Figure 6 In a more specific embodiment, the inner wall of the first pull-out member 2-114 is provided with an air inlet column 2-1144 for inputting defrosting gas, and the inner wall of the defrosting chamber 2-116 is provided with a clearance hole 2-116a for avoiding the air inlet column 2-1144, and the clearance hole 2-116a is connected to the third storage chamber 2-114a.

[0079] As can be seen, the connection between the first receiving chamber 2-110a and the third receiving chamber 2-114a is located directly below the air intake column 2-1144. When defrosting gas is introduced into the air intake column 2-1144, the defrosting gas that has just entered the first receiving chamber 2-110a will move forward along the axial direction of the air intake column 2-1144 under the action of inertia and the suction assembly 120. In this way, defrosting gas can be prevented from entering the third receiving chamber 2-114a as much as possible.

[0080] Furthermore, the clearance hole 2-116a in this embodiment not only avoids the air intake column 2-1144, but also serves to connect the first storage cavity 2-110a and the third storage cavity 2-114a, demonstrating the ingenuity of this design.

[0081] Furthermore, the inner wall of the defrosting chamber 2-116 is provided with an enclosure portion 2-1162 surrounding the clearance hole 2-116a, and the enclosure portion 2-1162 extends along the axial direction of the air intake column 2-1144. In this embodiment, the enclosure portion 2-1162 can prevent defrosting gas from entering the third receiving cavity 2-114a vertically through the clearance hole 2-116a.

[0082] In addition, to facilitate the user's retrieval or placement of the thawing compartment 2-116, lifting parts 1164 are provided on the inner walls on both sides of the thawing compartment 2-116.

[0083] Please see Figures 7-10 This invention proposes a second technical solution where the thawing chamber 3-116 is built into the first pull-out component 3-114. In this embodiment, the thawing chamber 3-116 is provided with a first partition 3-1162, which divides the first storage cavity 3-110a into a first liquid injection space 3-110a1 and a first placement space 3-110a2. The first liquid injection space 3-110a1 receives liquid matrix and is connected to the second storage cavity 110b. The first placement space 3-110a2 is used to place the substance to be thawed.

[0084] This embodiment proposes a technical solution where the first storage cavity 3-110a is relatively smaller, allowing the defrosting gas to quickly fill the first storage cavity 3-110a, thereby achieving a faster defrosting effect.

[0085] Furthermore, the user can add liquid matrix into the first injection space 3-110a1, and the liquid matrix in the first injection space 3-110a1 can flow into the second receiving cavity 110b connected to it. The user does not need to operate the heating chamber 118, making the operation more convenient.

[0086] like Figure 10 As shown, in one specific embodiment, the first separator 3-1162 has multiple connecting holes 3-1162a, which connect the first liquid injection space 3-110a1 and the first placement space 3-110a2. With this design, when the user adds liquid matrix, they can pour it directly over the first separator 3-1162, allowing the liquid matrix to pass through the connecting holes 3-1162a into the first liquid injection space 3-110a1. Furthermore, the defrosting gas generated by the heating component 130 can also pass through the multiple connecting holes 3-1162a into the first placement space 3-110a2. This design allows the defrosting gas to simultaneously pass through the multiple connecting holes 3-1162a and contact the substance to be defrosted, resulting in more uniform heating of the substance.

[0087] Preferably, the connecting hole 3-1162a is strip-shaped and evenly distributed on the first separator 3-1162.

[0088] Please continue reading. Figure 10 In a more specific embodiment, the bottom of the thawing chamber 3-116 is provided with a plurality of first support columns, which extend toward the first partition 3-1162, and the first partition 3-1162 is supported on the first support columns. The technical solution of this embodiment supports the first limiting member through the first support columns, which occupy relatively little space, thereby reserving more space for the liquid matrix and thawing gas.

[0089] In another more specific embodiment, a plurality of second support columns 3-1164 are provided at one end of the first separator 3-1162 away from the first liquid injection space 3-110a1. The second support columns 3-1164 extend away from the first liquid injection space 3-110a1 and are used to support the thawing substance.

[0090] It is worth mentioning that the design of the second support column 3-1164 in this embodiment can, on the one hand, prevent the material to be thawed from blocking the connecting hole 3-1162a, and on the other hand, it can elevate the material to be thawed, so that the material to be thawed can come into contact with the thawing gas in all directions, thereby achieving rapid thawing.

[0091] In another more specific embodiment, a first heating element is also provided in the thawing chamber 3-116. The first heating element is located in the first liquid injection space 3-110a1 and is used to heat the liquid matrix in the first liquid injection space 3-110a1.

[0092] In this embodiment, the first heating element can heat and generate thawing gas in the first liquid injection space 3-110a1, and work synchronously with the heating component 130 to further improve the thawing efficiency.

[0093] like Figure 9 and Figure 10 As shown, in another specific embodiment, the bottom surface of the first pull-out member 3-114 is provided with a plurality of third support columns 3-11663-1142 extending toward the thawing chamber 3-116, and the thawing chamber 3-116 is disposed on the third support columns 3-11663-1142.

[0094] It is understandable that the design of the third support column 3-11663-1142 in this embodiment can relatively increase the height of the thawing chamber 3-116, that is, increase the height of the first liquid injection space 3-110a1. In this way, the heating chamber 118 can be set at a relatively low height, so that the liquid matrix overflowing the orifice in the first liquid injection space 3-110a1 can flow into the second receiving cavity 110b under the effect of the height difference.

[0095] In addition, for ease of design, in this embodiment, the defrosting chamber 3-116 includes a first housing 3-1167 having a first storage cavity 3-110a, a first cover 3-1168 for sealing the first storage cavity 3-110a, and a first sealing member 3-1169 disposed between the first housing 3-1167 and the first cover 3-1168. The first sealing member 3-1169 is used to achieve a seal when the first cover 3-1168 and the first housing 3-1167 are engaged.

[0096] Please see Figures 11-14This invention also proposes an external defrosting chamber 4-116. In this embodiment, the rapid defrosting module 100 further includes a chassis 112 and an extension 119. The extension 119 is fixed to the chassis 112 and extends upwards from the chassis 112. The defrosting chamber 4-116 is fixed to the end of the extension 119 away from the chassis 112. The extension 119 has a first extension channel 119a and a second extension channel 119b. The first extension channel 119a connects the first receiving cavity 4-110a and the second receiving cavity 110b, and the second extension channel 119b connects the first receiving cavity 4-110a. The second extension channel 119b is used to output defrosting gas.

[0097] Before thawing, the user places the substance to be thawed into the first storage chamber 4-110a. The vacuum assembly 120 then operates, extracting air from both the first and second storage chambers 4-110a and 110b through the second extension channel 119b, creating a negative pressure environment in both chambers. At this time, the heating assembly 130 operates, heating the liquid matrix in the second storage chamber 110b and generating thawing gas. This thawing gas enters the first storage chamber 4-110a through the first extension channel 119a, exchanges heat with the substance, and then exits through the second extension channel 119b. This embodiment employs an external thawing chamber 4-116 design, allowing the user to directly operate the thawing chamber 4-116, making it convenient to use.

[0098] It is understood that the chassis 112 mentioned in this embodiment only embodies fixed technical features, and its shape can be as follows: Figure 11 The box structure shown can also be changed according to actual needs.

[0099] like Figures 13-14 As shown, in a specific embodiment, the thawing chamber 4-116 is provided with a second partition 4-1162, which divides the first receiving cavity 4-110a into a second liquid injection space 4-110a1 and a second placement space 4-110a2. The second liquid injection space 4-110a1 receives liquid matrix and is connected to the second receiving cavity 110b. The second placement space 4-110a2 is used to place the substance to be thawed.

[0100] Referring to the description of the first injection space 3-110a1 and the first placement space 3-110a2 mentioned in the above embodiments, in this technical solution, the user can add liquid to the heating chamber 118 through the second injection space 4-110a1 without operating the heating chamber 118.

[0101] In a more specific embodiment, a second heating element is also provided in the thawing chamber 4-116. The second heating element is located in the second liquid injection space 4-110a1 and is used to heat the liquid matrix in the second liquid injection space 4-110a1.

[0102] For ease of design, in this embodiment, the thawing chamber 4-116 includes a second housing 4-1164 having a first storage cavity 4-110a, a second cover 4-1166 for sealing the first storage cavity 4-110a, and a second sealing member 4-1168 disposed between the second housing 4-1164 and the second cover 4-1166. The second sealing member 4-1168 is used to achieve a seal when the second cover 4-1166 and the second housing 4-1164 are engaged.

[0103] Please see Figure 4 In another embodiment of the present invention, the chassis 112 has an installation space 112d, and the heating chamber 118 and the air extraction assembly 120 are both fixed in the installation space 112d; along the extension direction of the first pull-out channel 112a, the installation space 112d is located at the end of the first pull-out channel 112a away from the first pull-out member 2-114.

[0104] The technical solution of this embodiment, in terms of the design of the installation space 112d, can hide the heating chamber 118 and the air extraction component 120 within the user's field of vision, improving the aesthetics of the product using the rapid defrosting module 100. Furthermore, the holes for inputting defrosting or freezing gas can be located at the end of the first pull-out member 2-114 near the installation space 112d. When the first pull-out member 2-114 is fully inserted into the first pull-out channel 112a, these holes can mate with the heating chamber 118 or other structures.

[0105] In one specific embodiment, the chassis 112 is provided with an exhaust hole for discharging the defrosting gas in the first pull-out member 2-114; when the first pull-out member 2-114 is inserted into the first pull-out channel 112a, the exhaust hole is located above the first pull-out member 2-114 and is located at the corner of the first pull-out member 2-114 away from the installation space 112d.

[0106] This allows the distance between the intake column 2-1144 and the exhaust port to be relatively large, so that the defrosting gas can fully exchange heat with the substance to be defrosted before leaving from the exhaust port, which can also improve the defrosting efficiency.

[0107] Please see Figure 4 and Figure 5In another embodiment, the chassis 112 is also provided with a liquid storage tank 150, which has a liquid storage cavity 150a for storing liquid matrix. The liquid storage cavity 150a is connected to the second storage cavity 110b. The liquid storage tank 150 is used to provide liquid matrix to the heating chamber 118.

[0108] This embodiment proposes a liquid-adding method for the heating chamber 118. To effectively control the liquid addition, a valve is installed on the connecting pipe between the liquid storage chamber 150a and the second receiving chamber 110b. Firstly, the user can add liquid without further operation of the heating chamber 118. Secondly, the user can control the amount of liquid added from the liquid storage tank 150 to the heating chamber 118, thereby controlling the amount of liquid matrix within the heating chamber 118. In this way, the user can control the amount of liquid added based on the actual thawing time, thus preventing the accumulation of large amounts of liquid matrix in the heating chamber 118, and even ensuring that the liquid matrix in the heating chamber 118 is completely consumed after each thawing. Furthermore, an alarm structure can be installed in the heating chamber 118 to connect the liquid storage chamber 150a and the second receiving chamber 110b, or to shut down the heating component 130, after the liquid matrix has been consumed.

[0109] In one embodiment, the liquid storage tank 150 is positioned vertically above the heating chamber 118. Thus, the heating chamber 118 is closer to the ground than the liquid storage tank 150, allowing the liquid matrix within the liquid storage chamber 150a to flow towards the heating chamber 118 under gravity.

[0110] The liquid storage tank 150 is also provided with a liquid filling port for users to add liquid, and the heating chamber 118 is located on the side of the liquid storage tank 150 away from the liquid filling port.

[0111] Furthermore, the chassis 112 has a second pull-out channel 112b, within which the liquid storage tank 150 is slidably disposed. This improves the convenience of the rapid defrosting module 100.

[0112] Specifically, the second pull-out channel 112b is located above the first pull-out member 2-114. Combined with the feature in the above embodiment that the heating chamber is located on one side of the first pull-out member 2-114, the liquid matrix in the storage tank 150 can easily flow into the heating chamber 118.

[0113] Please continue reading. Figure 5 In one embodiment, the chassis 112 further includes a second pull-out member 140, the chassis 112 has a third pull-out channel 112c, the second pull-out member 140 is slidably disposed in the third pull-out channel 112c, and the second pull-out member 140 has a vacuum preservation chamber connected to the air extraction assembly 120.

[0114] As the name suggests, a vacuum preservation chamber improves preservation by removing oxygen from the chamber. In this embodiment, the air extraction component 120 can extract air from the vacuum preservation chamber even when not in thawing mode, thus improving the practicality of the air extraction component 120 and reducing resource waste.

[0115] Of course, valves are provided at the connection points between the air extraction component 120 and the vacuum preservation chamber and the thawing chamber 2-116 to allow for free switching between the two working modes.

[0116] Please continue reading. Figure 4 and Figure 5 In one embodiment, the rapid defrosting module 100 further includes a condensation component 160, which includes a condenser tube 162 with a condensation channel connected to the first receiving cavity 2-110a. The condenser tube 162 is used to cool the defrosting gas to generate a liquid matrix and is connected to the vacuum component 120.

[0117] In this embodiment, the thawing gas after heat exchange first passes through the condenser 162, which cools the water vapor in the thawing gas to liquefy it into a liquid matrix. The thawing gas, cooled by the condenser 162, is then introduced into the extraction assembly 120 and finally discharged. By employing this technical solution, the phenomenon of large-scale liquefaction of the thawing gas at the extraction assembly 120, which would otherwise affect the operation of the extraction assembly 120, can be avoided.

[0118] In one specific embodiment, the condensation channel is connected to the second receiving cavity 110b, so that the liquefied liquid matrix in the condensation channel flows back to the second receiving cavity 110b. The technical solution proposed in this embodiment can recycle the liquid matrix, demonstrating the energy-saving characteristics of the rapid defrosting module 100.

[0119] In yet another specific embodiment, the condensation assembly 160 further includes a condensation box 164 for receiving the liquefied liquid matrix within the condensation channel.

[0120] Furthermore, the chassis 112 also includes a cover plate 1122, which is fastened to the top of the chassis 112 and forms a second pull-out channel 112b.

[0121] Optionally, the condenser 162 is disposed between the cover plate 1122 and the chassis 112.

[0122] In addition, the chassis 112 also includes a third seal 170 and a fourth seal 180, which are used to seal the first pull-out piece 2-114 and the second pull-out piece 140 when they enter the chassis 112.

[0123] Please see Figure 15-16The present invention also proposes a refrigerator 200, which includes a rapid defrosting module 100. The specific structure of the rapid defrosting module 100 is as described in the above embodiments. Since the refrigerator 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0124] like Figure 15 As shown, in one embodiment, the refrigerator 200 includes a body 210 having a refrigerator compartment 210a and multiple support plates 212 stacked within the refrigerator compartment 210a. The multiple support plates 212 divide the refrigerator compartment 210a into multiple refrigerator spaces 210a1, and the rapid defrosting module 100 is disposed in the lowest refrigerator space 210a1. This embodiment can be combined with the technical solution mentioned in the above embodiments where the defrosting compartment is built into the casing 112, and the casing 112 is slidably disposed within the lowest refrigerator space 210a1 of the refrigerator 200. The first pull-out component and the second pull-out component 140 are both slidably disposed within the casing 112.

[0125] Alternatively, the defrosting compartment mentioned in the above embodiments can be externally mounted via an extension 119. The chassis 112 is slidably disposed within the lowest refrigeration space 210a1, the extension 119 passes through multiple refrigeration spaces 210a1, and the defrosting compartment is disposed at the end of the extension 119.

[0126] like Figure 16 As shown, in another embodiment, the refrigerator 200 includes a body 210 having a refrigerator compartment 210a and a door 220 covering the refrigerator compartment 210a, with a defrosting assembly 110 disposed on the door 220. This embodiment can be combined with the external defrosting assembly 110 solution mentioned in the above embodiments, in which the outline of the casing 112 is adapted and housed within the door 220 together with the extension 119.

[0127] Furthermore, the defrosting component 110 can be snapped onto the door 220, slidably mounted on the door 220, or hung on the door 220.
