The temperature of the refrigeration appliance, in particular in the freezer compartment, is low and has a large temperature difference with the ambient temperature, so that condensation is easily produced during operation of the refrigeration appliance. The condensation preventing pipe is generally arranged on the periphery of a door of a freezing chamber in the prior art, and high-temperature and high-pressure refrigerant steam is conveyed into the condensation preventing pipe through a compressor in a refrigeration module, so that the refrigeration module is assembled with the condensation preventing pipe when being installed in a refrigeration equipment body, and the restriction on the compactness of the refrigeration module and the assembly independence is generated.

In view of the above, the present invention provides a body assembly for use in a refrigeration appliance, such as a refrigeration appliance.

Referring to fig. 1 to 3, embodiments of the body assembly applied to a refrigeration device according to the present invention are shown in the drawings.

It should be noted that, in the following embodiments, the forward direction refers to a direction toward a user in a normal operating state of the refrigeration apparatus, and the backward direction refers to a direction away from the user of the refrigeration apparatus. The up-down direction is generally a vertical direction of a location where the refrigeration equipment is located.

Referring to fig. 1 to 3, the housing assembly of the present invention includes a housing 100, a refrigeration module 200, and a condensation preventing device 300. Wherein the case 100 is formed with a compartment 110 having a front opening 111; the refrigeration module 200 is detachably connected to the box body 100 and refrigerates the compartment 110; the anti-condensation device 300 comprises an anti-condensation pipe 310, a pump body 320, heat exchange liquid 330 and a heating component 340, wherein the anti-condensation pipe 310 and the pump body 320 are sequentially connected to form a circulation loop, the anti-condensation pipe 310 is arranged on the periphery of the chamber 110 in a surrounding mode along the circumferential direction of the opening 111, the heating component 340 is used for heating the anti-condensation pipe 310 and/or the heat exchange liquid 330, and the pump body 320 drives the heat exchange liquid 330 to circulate in the circulation loop in a circulating mode.

In the technical scheme provided by the utility model, under the action of the heating component 340, the temperature of the heat exchange liquid 330 can be kept within the temperature range meeting the anti-condensation requirement; after the anti-condensation pipe 310 is connected to the heat exchange liquid 330, the anti-condensation pipe 310 can conduct the temperature of the heat exchange liquid 330 to the box body 100 due to the heat conduction performance of the anti-condensation pipe 310, so that condensation caused by too low temperature at the position is prevented; because prevent that condensation pipe 310 encircles along the periphery that sets up at room 110 along the circumference of room 110 along opening 111, and pump body 320 drive heat transfer liquid 330 is in preventing that condensation pipe 310 inner loop circulates, can concentrate the heat transfer effect on the position that box 100 produced the condensation easily, and enlarge the heat transfer effect area as far as possible, help improving and prevent the condensation effect. The anti-condensation device 300 can independently realize the anti-condensation function without depending on the refrigeration module 200, so that the structural design and the assembly scheme of the refrigeration module 200 are not limited, and the structural miniaturization and the assembly simplification of the refrigeration module 200 are facilitated.

In the present design, the box 100 defines the compartment 110, and the compartment 110 is provided with an opening 111 to the outside environment, wherein the opening 111 is generally arranged towards the front. In addition, the body assembly generally further includes a door body movably connected to the cabinet 100, and the door body is configured to open or close the opening 111 of the compartment 110 during the movement of the door body.

In practical applications, the compartment 110 may be any cavity structure requiring anti-condensation treatment. It is understood that at least one compartment 110 among the refrigerating compartment 120, the freezing compartment 130, and the temperature varying compartment is formed on the cabinet 100 according to the system of the refrigerating apparatus. Among the refrigerating chamber 120, the freezing chamber 130, and the temperature-variable chamber, the freezing chamber 130 has a low operating temperature, and condensation is likely to occur on the peripheral side of the freezing chamber 130, and therefore, it is necessary to perform a condensation prevention process. Based on this, the anti-condensation device 300 may be disposed at a position corresponding to the freezing chamber 130 in practical use.

It should be noted that the box 100 may be directly recessed to form the compartment 110; alternatively, an installation space may be reserved in the box 100, and the machine body assembly further includes a liner structure (e.g., a liner of the freezing chamber 130), the liner structure is installed in the installation space, and a cavity of the liner structure correspondingly forms the compartment 110.

The anti-condensation device 300 is arranged corresponding to the compartment 110, and can be directly installed at a set position of the installation space, and then the inner container structure is installed; or, the anti-condensation device 300 may be fixedly connected with the liner structure in advance to form a whole, and then installed together with the liner structure into the installation space.

Of course, the anti-condensation device 300 is not limited to be installed in the box 100 from the opening 111, and the anti-condensation device 300 may be installed in the box 100 from any portion of the box 100, for example, from the bottom of the box 100 to the installation area, from the side of the box 100 to the installation area, etc., according to actual needs.

Specifically, in the anti-condensation device 300, the anti-condensation pipe 310 generally refers to a pipe body having a space formed therein to allow the heat exchange fluid 330 to flow therethrough, and a wall surface capable of conducting heat with the heat exchange fluid 330 communicated with the inside thereof. The technical scheme for realizing the function is various:

in an embodiment, the condensation preventing pipe 310 may have a heat exchange function by selecting a suitable material, specifically, for example, the condensation preventing pipe 310 is made of a heat conducting material, and the heat conducting material is, for example, a metal material with a better heat conducting property, so that when the heat exchanging liquid 330 circulates in the condensation preventing pipe 310, the heat exchanging liquid directly conducts contact heat with a contact portion of the condensation preventing pipe 310, dissipates heat outwards, and can perform heat exchange and temperature rise to an environment where the condensation preventing pipe 310 is located.

In an embodiment, the anti-condensation tube 310 may also have a heat exchange function by improving the structural characteristics thereof, specifically, for example, when a part of tube segments of the anti-condensation tube 310 extends along a horizontal direction (hereinafter referred to as a horizontal tube segment), and a liquid level of the heat exchange liquid 330 in the horizontal tube segment is less than a diameter of the horizontal tube segment, a cavity portion is defined in the horizontal tube segment, and the horizontal tube segment may be provided with heat dissipation holes on a tube wall corresponding to the cavity portion, so as to dissipate heat of the heat exchange liquid 330 through the heat dissipation holes.

Of course, the two embodiments listed above may be provided alternatively or simultaneously. For example, the entire tube body of the anti-condensation tube 310 may be made of a heat conductive material, and the heat dissipation holes may be formed at the position of the horizontal tube segment, which will not be described in detail herein.

In the process that the heat exchange liquid 330 circulates in the anti-condensation pipe 310, the temperature of the heat exchange liquid is at least not lower than the condensation temperature, so that after the heat exchange liquid 330 releases heat outwards, the temperature of the corresponding part of the box body 100 rises, and air cannot be condensed into fog at the part, thereby achieving the purpose of anti-condensation.

The specific expression of the heat exchange liquid 330 is not limited, and may be any liquid or gas capable of implementing the above heat exchange function. In this embodiment, the heat exchange liquid 330 may be a glycol solution obtained according to a predetermined ratio. It will be appreciated that ethylene glycol is a colorless, slightly viscous liquid with a boiling point of 197.4 deg.C and a freezing point of-11.5 deg.C, and can be mixed with water in any proportion. In addition, the freezing point of the glycol changes along with the concentration change of the glycol in the aqueous solution, and the proportion of the glycol solution can be adjusted according to the actual application requirements. Therefore, when the heat-exchange fluid 330 is specifically set to be a glycol solution, the freezing point of the heat-exchange fluid 330 can be ensured to be less than 0 ℃, and the heat-exchange fluid has good freezing resistance, can maintain a liquid state in a low-temperature environment of the freezing chamber 130, and is convenient for circulating circulation.

Based on the above embodiment, the anti-condensation pipe 310 may be in communication with other components, and obtain the heat exchange liquid 330 reaching the target temperature through other components; alternatively, as in the present embodiment, the circulation loop formed by the joint connection of the anti-condensation tube 310 and the pump body 320 is generally closed. The anti-condensation device 300 further includes a heating member 340, wherein the heating member 340 is disposed on the box body 100 and is used for heating the anti-condensation tube 310 and/or the heat exchange liquid 330. The heating part 340 may be, for example, a heating wire or the like; the heating component 340 is arranged at one position of the anti-condensation pipe 310 and heats the anti-condensation pipe 310 and/or the heat exchange liquid 330 in the heating area; the heat exchange fluid 330 in the heating area, after directly or indirectly obtaining heat, transfers heat to the entire periphery of the compartment 110 during its circulation along the entire circulation loop.

The heating member 340 may be provided in one or two or more. When the heating member 340 is provided in plurality, the heating members 340 may be arranged at intervals along the circulation loop. At least two of the plurality of heating parts 340 may be disposed in series or in parallel. The heating member 340 may be a member specially provided in the condensation preventing device 300, or may be another inherent member in the refrigeration apparatus, and waste heat generated during operation of the inherent member may be used to heat the condensation preventing pipe 310 and/or the heat exchange liquid 330.

Next, in an embodiment, the anti-condensation device 300 further includes a temperature sensor 350 and a control component, wherein the temperature sensor 350 is disposed on the box body 100 and is used for sensing a temperature value of the anti-condensation pipe 310 and/or the heat exchange liquid 330; the control component is electrically connected to the temperature sensor 350, the pump body 320 and the heating component 340, so as to control the operation of the pump body 320 and/or the heating component 340 according to the received temperature value.

It should be noted that, the control unit is electrically connected to the temperature sensor 350, and is capable of receiving the temperature value and analyzing and calculating the temperature value according to a set algorithm when the temperature sensor 350 senses and obtains the temperature value. The control component can also be electrically connected to at least one of the pump body 320 and the heating component 340, so as to control the operation of the pump body 320 and/or the heating component 340 connected thereto according to actual needs.

For example, when the temperature value is lower than the first temperature threshold, the power of the heating component 340 may be controlled to increase the heat carried by the heat-exchange liquid 330, and/or the rotation speed of the pump body 320 may be controlled to increase the flow speed and the flow rate of the heat-exchange liquid 330; conversely, when the temperature value is higher than the second temperature threshold, the power of the heating component 340 may be controlled to decrease to reduce the heat carried by the heat exchange liquid 330, and/or the rotation speed of the pump body 320 may be controlled to decrease to smooth the flow speed and flow rate of the heat exchange liquid 330. The first temperature threshold is smaller than the second temperature threshold, and can be specifically set according to actual application requirements.

The number and the positions of the temperature sensors 350 disposed on the condensation preventing pipe 310 are not limited. The temperature sensor 350 may be disposed upstream and/or downstream of the heating component 340, and when the temperature sensor 350 is disposed downstream of the heating component 340, the temperature sensor can sense the temperature of the heat exchange liquid 330 after being heated by the heating component 340, so that whether the heating component 340 is heating the heat exchange liquid 330 in place and whether the heat is suitable can be detected; when the temperature sensor 350 is disposed upstream of the heating member 340, the temperature of the heat exchange liquid 330 after the anti-condensation effect can be sensed, so that the amount of heat consumed by the anti-condensation effect in each current flow cycle can be detected. The temperature sensor 350 may be provided in one or more. When the temperature sensors 350 are provided in plurality, the temperature sensors 350 may be provided upstream and downstream of the heating member 340, so as to calculate the heating power of the heating member 340 according to the measured values of the temperature sensors 350, control the operation of the heating member 340, avoid the insufficient heat applied by the heating member 340 to the heat exchange liquid 330 from reducing the anti-condensation effect, and simultaneously prevent the excessive heat applied by the heating member 340 to the heat exchange liquid 330 from causing energy waste and affecting the refrigeration effect of the freezing chamber 130.

In addition, according to any of the above embodiments, a part of the tube section of the condensation preventing tube 310 is arranged with an expanded tube diameter to form the buffer cavity 311 at the expanded part. The buffer cavity 311 forms a sufficient space to buffer the kinetic energy generated by the heat exchange fluid 330 having a volume changed due to the change of the water temperature, thereby facilitating the uniform and stable circulation of the heat exchange fluid 330 throughout the circulation loop.

Specifically, when the anti-condensation pipe 310 is formed by bending the whole pipe body, a portion of the pipe section of the anti-condensation pipe 310 may be expanded during the molding of the anti-condensation pipe 310, so that the cross-sectional area of the buffer cavity 311 is formed to be larger than the cross-sectional area of the remaining pipe section of the anti-condensation pipe 310. When the anti-condensation tube 310 includes a plurality of tube units connected in sequence, at least one of the tube units may have a diameter larger than the diameter of the rest tube units.

The buffer cavities 311 can be arranged in the flow direction of the heat exchange liquid 330 with equal cross-sectional areas; alternatively, the buffer cavity 311 may be disposed with a gradually changing cross-sectional area in the flowing direction of the heat exchange liquid 330. When the cross-sectional area of the buffer cavity 311 is gradually changed, the cross-sectional area of the whole cavity section of the buffer cavity 311 may be gradually changed, or the cross-sectional area of a part of the cavity section of the buffer cavity 311 may be gradually changed. The gradual change setting can be gradually increased or gradually decreased, and the change process can be linear change or step-like interval change.

The buffer cavity 311 may be disposed at any position on the condensation preventing pipe 310, and may be one or more according to actual needs. When the buffer cavity 311 is provided in plural, the structures, sizes, shapes, etc. of the plural buffer cavities 311 may be the same, or at least partially different.

Further, in an embodiment, the buffer cavity 311 may be disposed at a side portion of the compartment 110. And the heat exchange liquid 330 is made to flow from top to bottom at the buffer cavity 311. Therefore, the heat exchange liquid 330 automatically passes through the buffer cavity 311 under the action of gravity, and after the buffer action is completed more quickly and sufficiently, the circulation is continued to exchange heat.

In addition, when the body assembly includes the heating member 340 as described above, the heating member 340 may be disposed in the buffer cavity 311, specifically, for example, in the buffer cavity 311. Because the cross-sectional area of the buffer cavity 311 is larger than the remaining pipe sections of the anti-condensation pipe 310, the flow rate of the heat exchange liquid 330 in the buffer cavity 311 is relatively larger, and the heat exchange liquid 330 in the buffer cavity 311 is heated, so that the single heating amount of the heat exchange liquid 330 can be increased, and the heating efficiency of the heating component 340 on the heat exchange liquid 330 is increased.

In any of the embodiments, after the installation position of the condensation preventing device 300 in the box 100 is accurately and relatively fixed, a set area inside the box 100 and outside the compartment 110 may be foamed, and a foaming material may be filled so as to cover the periphery of the condensation preventing device 300 and the periphery of the compartment 110, for example, the freezing compartment 130, and perform heat preservation.

In view of the above, the refrigeration module 200 may generally include an evaporator, a condenser and a compressor which are connected in sequence to form a refrigeration circuit, and may also include various valve bodies, capillary tubes, etc., which are all mature technologies, and are not described herein in detail.

The anti-condensation device 300 is configured to eliminate a connection operation between the anti-condensation device 300 and the refrigeration module 200, so that the anti-condensation device 300 and the refrigeration module 200 are independent from each other and are not substantially associated with each other. The structure and the assembly of the refrigeration module 200 do not need to consider the pre-embedding of the traditional anti-condensation pipe, and the evaporator in the refrigeration module 200 does not have a heat insulation structure, so that the assembly and the heat insulation of the heat insulation structure of the evaporator and the box body 100 do not need to be solved. Therefore, the anti-condensation device 300 does not excessively limit the structure and assembly of the refrigeration module 200, so that the refrigeration module 200 has more selectivity in the structural design and assembly scheme thereof, and the refrigeration module 200 can be separately designed and separately produced from the structure of the box 100 and the like, thereby enabling the miniaturization and the assembly simplification of the refrigeration module 200 as much as possible.

And after the refrigeration module 200 is installed inside the cabinet 100, since the refrigeration module 200 needs to refrigerate the freezing chamber 130, at least an evaporator, etc. of the refrigeration module 200 is disposed adjacent to the freezing chamber 130. Therefore, under appropriate circumstances, heat generated during the operation of the condenser, for example, can be further utilized to assist the heat exchange of the anti-condensation device 300.

After the assembly of the refrigeration module 200 is completed, the refrigeration function can be realized by, for example, vacuuming and adding a refrigerant. After the refrigeration module 200 is mounted to the box 100, in an embodiment, the box 100 is provided with a mounting cavity 140, the mounting cavity 140 provides a mounting space for the refrigeration module 200, and the mounting cavity 140 may be specifically disposed at the bottom of the rear side of the box 100 and adjacent to the compartment 110, which is beneficial to the assembly between the refrigeration module 200 and the box 100 and the aesthetic property of the whole machine.

After the refrigeration module 200 is installed in the installation cavity 140, the air supply pipeline, the air return pipeline, and the like of the refrigeration module 200 may be connected to, for example, an air duct inside the cabinet 100, so as to complete the assembly of the refrigeration module 200.

In addition, the utility model also provides refrigeration equipment which comprises the machine body assembly. It should be noted that, the detailed structure of the machine body assembly in the refrigeration equipment may refer to the above embodiment of the machine body assembly, and is not described herein again; since the machine body assembly is used in the refrigeration apparatus of the present invention, the embodiment of the refrigeration apparatus 1 of the present invention includes all technical solutions of all embodiments of the machine body assembly, and the achieved technical effects are also completely the same, and are not described herein again.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
