Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigeration device. Background Technology

[0002] A freezer is a refrigeration device that uses refrigeration technology to maintain a low temperature. It is mainly used for low-temperature food storage to increase the storage time and freshness of food.

[0003] The freezer contains an evaporator, which lowers the air temperature and uses air ducts to guide the cold air into the storage space, maintaining a low temperature. A heater is usually located on the side of the evaporator to melt frost. Typically, the end plate of the evaporator has an assembly slot to accommodate the heater; tools are used to pinch the clamps on both sides of the assembly slot towards the center, deforming and closing the clamps to hold the heater.

[0004] However, this method of fixing the heater is not only complicated to operate and has low assembly efficiency, but the clamps are also prone to damaging the heater. Utility Model Content

[0005] This application provides a refrigeration device to improve the assembly efficiency of the heater and reduce damage to the heater caused by the fixed structure.

[0006] In a first aspect, embodiments of this application provide a refrigeration device, which includes:

[0007] The housing includes a storage chamber and an evaporation chamber, with an air duct between the evaporation chamber and the storage chamber for cold air from the evaporation chamber to flow into the storage chamber.

[0008] An evaporator is disposed within the evaporation chamber; an assembly groove is provided on the end plate of the evaporator, the assembly groove extends along a first direction, and the assembly groove extends to the edge of the end plate;

[0009] A heater is disposed inside the evaporation chamber and in contact with the evaporator for defrosting the evaporator; the end of the heating tube of the heater passes through the assembly groove.

[0010] The end plate is further provided with a buckle, which is located on the side of the assembly groove along the second direction; at least a portion of the projection of the buckle and the heating tube toward the extension plane of the end plate coincides along the first direction; the second direction intersects the first direction;

[0011] A fixing rib extends along the second direction, with both ends of the fixing rib connected to the end plate, and the fixing rib is inserted between the heating tube and the buckle.

[0012] The refrigeration device of this application embodiment provides a buckle on the side of the assembly groove along the second direction, with the buckle and the heating tube spaced apart along the first direction. The refrigeration device adds a fixing rib, the two ends of which are connected to the end plate and snapped between the heating tube and the buckle, thereby pressing the heating tube into the assembly groove and fixing it to the end plate. No tools are required; the fixing rib is simply snapped between the heating tube and the buckle, simplifying operation and improving assembly efficiency. Furthermore, the buckle does not contact the heating tube; the heating tube is only pressed into the assembly groove by the fixing rib, reducing contact between the heating tube and other components and minimizing the possibility of damage to the heating tube. At least a portion of the projection of the buckle and the heating tube onto the end plate coincides along the first direction, causing the fixing member to be subjected to a force from the buckle towards the end plate, preventing the fixing member from detaching from the buckle and affecting the restraining effect on the heating tube.

[0013] In some embodiments of this application, the fixing rib includes:

[0014] A rib body, which extends along the second direction and is engaged between the heating tube and the buckle;

[0015] The first connecting part is disposed at one end of the extension direction of the rib body and is connected to the end plate;

[0016] The second connecting part is located at the other end of the extension direction of the rib body and is connected to the end plate.

[0017] In this embodiment of the application, the fixing rib is provided with a rib body, which is snapped between the heating tube and the buckle to press the heating tube into the assembly groove. It is connected to the end plate through the first connecting part and the second connecting part, thereby installing the fixing rib on the end plate.

[0018] In some embodiments of this application, a first connection hole is provided on the end plate;

[0019] One end of the rib body extending in the direction of extension is bent toward the end plate to form the first connecting portion; the first connecting portion is inserted into the first connecting hole.

[0020] The first connecting part of this application embodiment is inserted into the first connecting hole, which makes the connection between the first connecting part and the end plate simple and the assembly efficiency high.

[0021] In some embodiments of this application, a second connection hole is provided on the end plate;

[0022] The other end of the rib body extending in the direction of extension is bent toward the end plate to form a first connecting segment; the first connecting segment is bent away from the first connecting portion to form a second connecting segment; the second connecting portion includes the first connecting segment and the second connecting segment;

[0023] The first connecting segment passes through the second connecting hole, and the second connecting segment is located on the side of the end plate away from the rib body.

[0024] In this embodiment of the application, the first connecting segment of the second connecting part passes through the second connecting hole, so that the second connecting segment is located on the side of the end plate facing the fin and abuts against the end plate, thereby improving the reliability of the connection between the second connecting part and the end plate.

[0025] In some embodiments of this application, the end plate is provided with a curved cut, and the portion surrounded by the cut is bent relative to the side of the end plate facing the opening of the assembly groove to form the buckle.

[0026] With this design, the buckle and end plate are integrally formed, resulting in a stable structure. The buckle can be formed simply by punching a notch and then bending it, making the forming method and structure simple. Moreover, the buckle is plate-shaped and inclined relative to the end plate, with the end of the buckle that is further away from the end plate facing the heating tube, which helps the heating tube to be snapped into the buckle.

[0027] In some embodiments of this application, the bending angle of the buckle is an acute angle.

[0028] With this configuration, along the first direction from the opening end of the buckle to the connection end between the buckle and the end plate, the gap between the buckle and the end plate gradually decreases along the third direction, and the restraining force on the fixing rib gradually increases. This ensures the stability of the fixing rib in place between the buckle and the heating tube, thereby improving the stability of the fixing rib in pressing the heating tube into the assembly groove. Moreover, by adjusting the bending angle of the buckle, the restraining force of the buckle on the fixing rib can be adjusted, which is beneficial for application to heating tubes of different sizes.

[0029] In some embodiments of this application, at least a portion of the outer surface of the fixing rib is an arc-shaped surface, and the arc-shaped surface is in contact with the heating tube.

[0030] This design ensures that there are no sharp contacts between the fixing ribs and the heating element, which helps protect the heating element.

[0031] In some embodiments of this application, multiple buckles are provided, and the multiple buckles are arranged at intervals along the second direction.

[0032] This helps improve the reliability of the fixing rib engaging with the buckle and the heating tube, thereby improving the reliability of the fixing rib pressing the heating tube into the assembly slot.

[0033] In some embodiments of this application, multiple assembly slots are provided, and the multiple assembly slots are arranged at intervals along the second direction;

[0034] The plurality of assembly slots and the plurality of snaps are arranged alternately at intervals along the second direction.

[0035] This causes the contact positions between the clip and the fixing rib to be offset from those between the fixing rib and the heating tube along the second direction, which helps the fixing rib to deform and snap into the space between the heating tube and the clip, improving the ease of assembly of the fixing rib; it also helps to improve the stability and reliability of the heating tube assembly.

[0036] Secondly, embodiments of this application provide a refrigeration device, which includes:

[0037] The housing contains an evaporation chamber; the evaporation chamber contains an evaporator and a heater for defrosting the evaporator.

[0038] The evaporator end plate is provided with an assembly slot;

[0039] The end of the heating tube of the heater passes through the assembly groove;

[0040] The evaporator end plate is also provided with a buckle, which is located on the side of the assembly groove along the second direction; there is a gap between the buckle and the heating tube along the first direction, and the gap has a first size; the second direction and the first direction intersect, and the plane defined by the second direction and the first direction is parallel to the extension plane of the end plate;

[0041] The fastener has its two ends fixed to the end plate, and the projection of the fastener toward the extension plane of the end plate has a second dimension along the first direction, the second dimension being smaller than the first dimension; the fastener is deformed and engaged between the buckle and the heating tube.

[0042] The refrigeration device of this application embodiment features a buckle on the side of the assembly groove along the second direction, with the buckle spaced from the heating tube along the first direction. The refrigeration device adds a fixing member, whose two ends are connected to an end plate and snap into place between the heating tube and the buckle, thereby pressing the heating tube into the assembly groove and fixing it to the end plate. No tools are required; the fixing member is simply snapped into place between the heating tube and the buckle, simplifying operation and improving assembly efficiency. Furthermore, the buckle does not contact the heating tube; the heating tube is only pressed into the assembly groove by the fixing member, reducing contact between the heating tube and other components and minimizing the possibility of damage to the heating tube. The second dimension of the fixing member is smaller than the first dimension between the buckle and the heating tube, causing the fixing member to be subjected to a force from the buckle towards the end plate, preventing the fixing member from detaching from the buckle and affecting its restraining effect on the heating tube.

[0063] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0064] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0065] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0066] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0067] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0068] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0069] During the use of a freezer, water vapor from the outside environment enters the storage compartment when the door is opened. The food stored in the compartment contains moisture, and this moisture in the air condenses into frost as it passes over the evaporator. When the frost reaches a certain thickness, it affects the smooth flow of air through the evaporator, thus impacting the cooling effect. Therefore, regular defrosting is necessary. A heater is usually installed on the side of the evaporator to melt the frost.

[0070] Typically, the end plate of the evaporator has an assembly slot to accommodate the heater. Notches are formed on both sides of the assembly slot, with gaps between the notches and the assembly slot forming clamps. To assemble the heater and evaporator, the heater is first placed in the assembly slot, and then a tool, such as pliers, is used to pinch the clamps on both sides of the assembly slot towards the center, deforming and closing the clamps to hold the heater.

[0071] However, this method of fixing the heater is not only complex to operate and inefficient to assemble, but the clamps can also easily damage the heater during assembly or transportation. In particular, when the heater uses aluminum tubing, its soft texture makes it easy to be scratched by the clamps, leading to leakage and affecting safety.

[0072] In view of this, the embodiments of this application utilize fixing ribs and buckles. The fixing ribs are snapped between the buckles and the heating tube of the heater, thereby pressing the heating tube into the assembly groove. No operating tools are required, and the assembly efficiency is high. Moreover, in the fixed position, the heating tube only contacts the fixing ribs and the groove wall of the assembly groove, which helps to improve the safety of the heating tube and reduce the possibility of the heating tube being scratched.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] Combination Figure 1 This application provides a refrigeration device, which can be a household or commercial device such as a freezer, refrigerator, or display case.

[0075] The refrigeration equipment may include a housing 100, which may be configured to form a storage compartment 101 with an opening on one side for storing items. Figure 1 As shown, the opening of the storage compartment 101 faces upward. In some embodiments, the opening of the storage compartment 101 may face the front of the housing 100.

[0076] The cabinet 100 may include a cabinet liner and a cabinet shell. The cabinet liner may be configured to form a storage compartment 101. The cabinet shell may be attached to the outside of the cabinet liner to form the appearance of the refrigeration equipment.

[0077] The enclosure 100 may also include an insulation layer, which can be disposed between the inner liner and the outer shell. The insulation layer can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigeration equipment, thus helping to ensure the refrigeration effect of the refrigeration equipment.

[0078] The refrigeration device in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment 101. Exemplarily, the refrigeration system may be housed within the enclosure 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0079] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside storage compartment 101.

[0080] The refrigeration equipment in this application embodiment may further include a door 200, which can be rotatably connected to the cabinet 100 via a hinge to open or close the storage compartment 101.

[0081] When the opening of the storage compartment 101 is facing upwards, the door 200 is located above the box 100. The door 200 rotates upwards to open the storage compartment 101, and rotates downwards to close the storage compartment 101.

[0082] In some implementations, the door body 200 may include an inner door liner. When the door body 200 closes the storage compartment 101, the inner door liner faces the storage compartment 101.

[0083] The door body 200 may further include a door shell; the door shell may be attached to the outside of the door inner liner to form the appearance of the door body 200. The door shell and the housing shell are rotatably connected by hinges to allow the door body 200 to open or close the storage compartment 101.

[0084] The door body 200 may also include a door insulation component, which can be disposed within the gap between the inner door liner and the outer door shell. The door insulation component can insulate the storage compartment 101 to minimize heat exchange between the storage compartment 101 and the outside of the refrigeration equipment, thereby helping to ensure the refrigeration effect of the refrigeration equipment. The door insulation component can be a foam layer.

[0085] In some embodiments, the refrigeration equipment may further include a duct component installed inside the cabinet to divide the cabinet into an evaporation chamber and a storage compartment 101. An evaporator 300 is disposed inside the evaporation chamber. The duct component is configured to form a duct that connects the storage compartment 101 and the evaporation chamber, so that cold air from the evaporation chamber flows into the storage compartment 101.

[0086] Combination Figure 2 and Figure 3 The evaporator 300 may include a refrigerant pipe 330 and multiple fins 320. The refrigerant pipe 330 is for refrigerant to flow through, and the fins 320 are provided with through holes for the refrigerant pipe 330 to pass through, so that the fins 320 can be sleeved on the outside of the refrigerant pipe 330.

[0087] The refrigerant pipe 330 may include straight pipe sections and U-shaped pipe sections, with the two ends of the U-shaped pipe sections connected to the straight pipe sections, making the refrigerant pipe 330 approximately S-shaped. Figure 2 In the middle, the straight section of the refrigeration pipe 330 extends along the Y-axis direction.

[0088] Multiple fins 320 can be arranged at intervals along the length of the refrigerant pipe 330, so that the projection of the evaporator 300 on the bottom surface of the casing 100 is approximately rectangular. The length of the refrigerant pipe 330 extends in the same direction as the straight pipe section, corresponding to... Figure 2 The Y-axis direction in the diagram.

[0089] The evaporator 300 may also include an end plate 310, which may be arranged parallel to the fins 320. The end plate 310 may have through holes for the refrigerant pipes 330 to pass through, allowing the fins 320 to be fitted over the outside of the refrigerant pipes 330, thus providing support for both the refrigerant pipes 330 and the fins 320. The end cap may also be connected to other structures of the refrigerator to facilitate the installation of the evaporator 300.

[0090] There can be two end plates 310, located at both ends of the length extension direction of the cooling pipe 330, and all the fins 320 are located between the two end plates 310.

[0091] Continue to refer to Figure 2 and Figure 3 The refrigeration equipment may also include a heater 400, which is disposed in the evaporation chamber and in contact with the evaporator 300 for defrosting the evaporator 300.

[0092] The heater 400 may include a heating element 410 and a connecting cable 420. The heating element 410 is in contact with the evaporator 300 and serves to heat and defrost. The heating element 410 includes a tube body and a heating wire disposed within the tube body. The connecting cable 420 is used to electrically connect to the heating wire to supply power to the heating wire.

[0093] The heating tube 410 can be arranged in an S-shape to increase the contact points between the heating tube 410 and the evaporator 300, thereby helping to improve defrosting efficiency.

[0094] The heating element 410 may include multiple first pipe segments 411 and multiple second pipe segments 412. The first pipe segments 411 can be straight pipes, extending along the length of the cooling pipe 330. Multiple first pipe segments 411 can be spaced apart along the length of the end plate 310. The second pipe segments 412 can be curved pipe segments to connect adjacent first pipe segments 411, and both ends of the first pipe segment 411 are connected to curved pipe segments, thus making the heating element 410 extend in an approximately S-shape. The length direction of the end plate 310 can correspond to... Figure 3 In the X-axis direction, the length direction of the end plate 310 can be perpendicular to the length direction of the refrigerant pipe 330, and the thickness direction of the end plate 310 is parallel to the length direction of the refrigerant pipe 330.

[0095] Continue to refer to Figure 3 The refrigeration equipment may also include a temperature sensor 610, which is installed on the surface of the evaporator 300 to monitor the temperature of the surface of the evaporator 300 and to control the start and stop of defrosting of the evaporator 300.

[0096] When temperature sensor 610 detects that the surface temperature of evaporator 300 is lower than the set first temperature threshold, it indicates that frost has formed severely on the surface of evaporator 300, and defrosting is required. The controller of the refrigeration equipment, based on the surface temperature of evaporator 300 detected by temperature sensor 610, controls heater 400 to start, thus defrosting evaporator 300. When temperature sensor 610 detects that the surface temperature of evaporator 300 is higher than the set second temperature threshold, it indicates that defrosting of evaporator 300 is complete, and defrosting needs to be stopped. The controller of the refrigeration equipment, based on the surface temperature of evaporator 300 detected by temperature sensor 610, controls heater 400 to stop, thus defrosting evaporator 300.

[0097] Of course, this is only an exemplary description of the defrosting determination conditions for the evaporator 300. The controller of the refrigeration equipment can comprehensively determine whether to start the heater 400 for defrosting based on the temperature of the evaporator 300 surface detected by the temperature sensor 610 and other conditions.

[0098] In some embodiments, the refrigeration equipment may further include a defrost fuse 620, which is a thermal fuse that may be disposed on the surface of the evaporator 300. When the surface temperature of the evaporator 300 rises abnormally, the defrost fuse 620 disconnects the circuit, forcibly cutting off the power supply to the heater 400, thereby preventing the heater 400 from overheating and causing a malfunction.

[0099] The defrosting fuse 620, temperature sensor 610, and connecting cable 420 can all be connected to the connecting terminal 630, and electrically connected to the control device of the refrigeration equipment through the connecting terminal 630, simplifying the electrical connection of the electrical components.

[0100] Reference Figure 4 During the defrosting process, the evaporator 300 produces defrost water. For this purpose, the refrigeration equipment is also equipped with a water tray 500, at least a portion of which is located below the evaporator 300 to collect the defrost water produced during the defrosting process.

[0101] In some embodiments, the drip tray 500 may include a base portion 510 located below the evaporator 300 for receiving defrost water from the evaporator 300. The base portion 510 is connected to a drain pipe to discharge the defrost water to the outside of the refrigeration unit.

[0102] The water tray 500 may include a side plate portion 520, which is disposed on one side of the chassis portion 510. A baffle may be provided between the side plate portion 520 and the evaporator 300 to guide air through the interior of the evaporator 300 and improve the heat exchange effect between the air and the evaporator 300.

[0103] In some embodiments, the chassis portion 510 can be a metal part, such as an aluminum disc, which has good heat dissipation performance and helps to improve defrosting efficiency.

[0104] Combination Figure 3 In some embodiments, the heating tube 410 of the heater 400 may be provided with two heating elements 430, which are respectively arranged on both sides of the heater 400 along the width direction of the end plate 310. The width direction of the end plate 310 is perpendicular to the length direction of the cooling tube 330 and perpendicular to the length direction of the end plate 310. The width direction of the end plate 310 can be... Figure 3 The Z-axis direction in the middle. The two heating elements 430 each include a plurality of first tube segments 411 and a plurality of second tube segments 412, and the two heating elements 430 are arranged in an S-shape.

[0105] One heating element 430 is located on the side of the evaporator 300 opposite to the chassis 510, and there is a gap between two adjacent first pipe sections 411 of the heating element 430 along the length of the end plate 310. In some embodiments, air flows through the evaporator 300 along the length of the end plate 310. The left side of the evaporator 300 is close to the return air inlet, which connects the evaporation chamber and the storage chamber 101, so that air in the storage chamber 101 can return to the evaporation chamber through the return air inlet. Therefore, the left side of the evaporator 300 is more severely frosted than the right side. Therefore, the gap between two adjacent first pipe sections 411 on the left side of the heating element 430 is smaller, while the gap between two adjacent first pipe sections 411 on the right side of the heating element 430 is larger. The left side of the evaporator 300 can be... Figure 3 On the negative side of the X-axis. This arrangement allows for a denser arrangement of heating elements 410 in areas of the evaporator 300 with severe frost buildup, and a sparser arrangement in areas with less frost, improving the uniformity of defrosting across the entire evaporator 300. Furthermore, the upper part of the evaporator 300 is close to the air duct; fewer heating elements 410 reduce the likelihood of damaging the air duct.

[0106] Another heating element 430 is located between the water receiving tray 500 and the evaporator 300, and the distance between two adjacent first pipe sections 411 of this heating element 430 along the length direction of the end plate 310 (corresponding to...) Figure 3 The heating tubes 410 of the heating section 430 have a first interval in the X-axis direction. The first interval can be equal to the interval between two adjacent first tube segments 411 in the left region of the upper heating section 430, and the first interval can be smaller than the interval between adjacent first tube segments 411 in the right region of the upper heating section 430, so that the heating tubes 410 of the heating section 430 are relatively dense, which helps to improve defrosting efficiency.

[0107] Continue to refer to Figures 2 to 4In some embodiments, an assembly groove 311 is provided on the end plate 310 of the evaporator 300. The assembly groove 311 can extend along a first direction and extends to the edge of the end plate 310. The first direction corresponds to... Figure 3 In the Z-axis direction. The assembly groove 311 extends through the end plate 310 along its thickness direction (corresponding to the Y-axis direction in the figure). The assembly groove 311 opens on one side along the first direction, and the opening of the assembly groove 311 faces the edge of the end plate 310. The heating tube 410 enters the assembly groove 311 through the opening.

[0108] When heating tubes 410 are provided on both the upper and lower sides of the evaporator 300, assembly slots 311 are respectively provided on the upper and lower sides of the two end plates 310. The upper and lower directions correspond to... Figure 3 In the Z-axis direction. The opening directions of the assembly grooves 311 on the upper and lower sides of the same end plate 310 are opposite. Mating grooves 321 are respectively provided on the upper and lower sides of the fins 320 to accommodate at least part of the heating tubes 410, so that the heating tubes 410 contact the evaporator 300, which helps to improve the defrosting efficiency of the evaporator 300.

[0109] Combination Figure 5 In some embodiments, the bottom wall of the assembly groove 311 is arc-shaped to fit the cylindrical heating tube 410, increasing the contact area between the assembly groove 311 and the heating tube 410, which helps to improve the stability of the heating tube 410 installation. Arc-shaped rounded corners are provided on both sides of the opening of the assembly groove 311 to prevent the heating tube 410 from being scratched by sharp parts when it enters the assembly groove 311.

[0110] The end of the heating tube 410 passes through the assembly groove 311. The end of the first tube section 411 of the heating tube 410 is engaged with the assembly groove 311, and the second tube section 412 is located on the outside of the end plate 310 away from the fins 320.

[0111] The end plate 310 is also provided with a buckle 313, which is located on the side of the assembly groove 311 along the second direction; the second direction can correspond to Figure 5 In the X-axis direction.

[0112] In some embodiments, at least a portion of the projections of the latch 313 and the heating tube 410 along a third direction onto the extending plane toward the end plate 310 coincide along the first direction, such that the fastener is subjected to a force from the latch 313 toward the end plate 310, preventing the fastener from dislodging from the latch 313 and affecting the restraining effect on the heating tube 410. The second direction intersects the first direction, and the plane defined by the second and first directions intersects the third direction. The third direction can be... Figure 3 The Y-axis direction in the middle, the second direction can be Figure 3 The X-axis direction in the diagram, the first direction can be... Figure 3The Z-axis direction. This arrangement ensures that the latch 313 and the heating tube 410 have a small gap along the first direction.

[0113] There is a gap between the latch 313 and the heating tube 410 along a first direction, and the gap has a first dimension. The first dimension can be the dimension between the bottom end of the latch 313 and the top end of the heating tube 410 along the first direction. A second direction intersects the first direction, and the plane defined by the second direction and the first direction is parallel to the extension plane of the end plate 310; the second direction can be... Figure 3 The X-axis direction in the diagram, the first direction can be... Figure 3 The Z-axis direction; the end plate 310 is arranged in the XZ plane.

[0114] The refrigeration device in this embodiment may further include a fixing member, both ends of which are fixed to the end plate 310. The projection of the fixing member onto the extension plane of the end plate 310 along a third direction has a second dimension along a first direction, which is smaller than the first dimension. This allows the fixing member to be subjected to a force from the latch 313 towards the end plate 310, preventing the fixing member from dislodging from the latch 313 and affecting the restraining effect on the heating tube 410. It can be understood that the second dimension of the fixing member along the first direction is smaller than the gap between the latch 313 and the heating tube 410. When the fixing member deforms and engages between the latch 313 and the heating tube 410, the fixing member can press the heating tube 410 tightly into the assembly groove 311.

[0115] The fastener can be a strip-shaped structure, a sheet-shaped structure, a rib-shaped structure, etc. The fastener can be a metal part, with a stable structure that facilitates elastic deformation, so as to be locked between the buckle 313 and the heating tube 410.

[0116] In some embodiments, refer to Figure 6 and Figure 7 The fixing component is a fixing rib 700, which has a small cross-section, occupies little space during installation, and is easy to assemble. The fixing rib 700 extends along the second direction, and both ends of the fixing rib 700 are connected to the end plate 310. The fixing rib 700 can elastically deform and snap into the heating tube 410 and the buckle 313.

[0117] When the cross-section of the fixing rib 700 is circular, the second dimension is the diameter of the fixing rib 700. The cross-section is the section formed by cutting the fixing rib 700 with a plane perpendicular to the extension direction of the fixing rib 700.

[0118] Therefore, in this embodiment, by providing a buckle 313 on the side of the assembly groove 311 along the second direction, and by spacing the buckle 313 from the heating tube 410 along the first direction, the refrigeration device adds a fixing rib 700. The two ends of the fixing rib 700 are connected to the end plate 310 and are inserted between the heating tube 410 and the buckle 313, thereby pressing the heating tube 410 into the assembly groove 311 and fixing it to the end plate 310. No tools are needed; the fixing rib 700 can be directly inserted between the heating tube 410 and the buckle 313, simplifying the operation and improving assembly efficiency. Furthermore, the buckle 313 does not contact the heating tube 410; the heating tube 410 is only pressed against the assembly groove 311 by the fixing rib 700, reducing contact between the heating tube 410 and other components and helping to reduce the possibility of damage to the heating tube 410.

[0119] Reference Figure 8 In some embodiments, the fixing rib 700 includes: a rib body 710, which extends along a second direction and is engaged between the heating tube 410 and the buckle 313.

[0120] The fixing rib 700 also includes a first connecting portion 720, which is disposed at one end of the rib body 710 in the extending direction.

[0121] The fixing rib 700 also includes a second connecting portion 730, which is disposed at the other end of the rib body 710 in the extending direction.

[0122] The first connecting part 720 and the second connecting part 730 are respectively connected to the end plate 310, so that the fixing rib 700 is installed on the end plate 310.

[0123] In some embodiments, the first connecting portion 720 and the second connecting portion 730 are respectively snapped into the end plate 310, making the connection between the fixing rib 700 and the end plate 310 simple and without the need for tools, which helps to improve the efficiency of the heater 400 being installed on the end plate 310.

[0124] Combination Figure 3 , Figure 5 and Figure 8 The end plate 310 is provided with a first connecting hole 314. One end of the rib body 710 extending in the direction of extension is bent toward the end plate 310 to form a first connecting part 720; the first connecting part 720 is inserted into the first connecting hole 314. The extending direction of the first connecting part 720 may be perpendicular to the extending direction of the rib body 710.

[0125] The first connecting portion 720 is formed by bending the end of the rib body 710, making the first connecting portion 720 and the rib body 710 an integral piece, which helps to ensure the structural strength of the fixing rib 700. Moreover, the cooperation between the first connecting portion 720 and the first connecting hole 314 allows the first connecting portion 720 to rotate relative to the end plate 310, which helps to improve the engagement of the fixing rib 700 between the buckle 313 and the heating tube 410.

[0126] The first connecting part 720 of this application embodiment is inserted into the first connecting hole 314, which makes the connection between the first connecting part 720 and the end plate 310 simple and the assembly efficiency high.

[0127] Continue to refer to Figure 3 , Figure 5 as well as Figure 8 The end plate 310 is provided with a second connecting hole 315. The second connecting hole 315 and the first connecting hole 314 are respectively located at both ends of the end plate 310 along the second direction.

[0128] The other end of the reinforcing bar body 710 is bent toward the end plate 310 to form a first connecting segment 731; the first connecting segment 731 is bent away from the first connecting portion 720 to form a second connecting segment 732; the second connecting portion 730 includes the first connecting segment 731 and the second connecting segment 732. The extending direction of the first connecting segment 731 may be perpendicular to the extending direction of the reinforcing bar body 710, and the extending direction of the second connecting segment 732 may be parallel to the extending direction of the reinforcing bar body 710. The connection between the first connecting segment 731 and the reinforcing bar body 710, and the connection between the first connecting segment 731 and the second connecting segment 732, may both be arc-shaped connections, which helps to improve the structural strength of the fixing reinforcing bar 700.

[0129] The first connecting section 731 passes through the second connecting hole 315, and the second connecting section 732 is located on the side of the end plate 310 away from the reinforcing bar body 710.

[0130] Thus, by bending the end of the rib body 710 to form the second connecting part 730, not only can the second connecting part 730 and the rib body 710 be integrated as one piece, which helps to ensure the structural strength of the fixing rib 700, but also simplifies the processing of the fixing rib 700.

[0131] In this embodiment of the application, the first connecting segment 731 of the second connecting part 730 passes through the second connecting hole 315, so that the second connecting segment 732 is located on the side of the end plate 310 facing the fin 320 and abuts against the end plate 310, thereby improving the reliability of the connection between the second connecting part 730 and the end plate 310.

[0132] With the above setup, the fixing rib 700 can be formed by bending a straight rib, which is simple to form and helps to reduce costs.

[0133] In some embodiments, at least a portion of the outer surface of the fixing rib 700 is an arc-shaped surface, and the arc-shaped surface contacts the heating tube 410. This arrangement ensures that there is no sharp contact between the fixing rib 700 and the heating tube 410, which helps to protect the heating tube 410.

[0134] For example, the cross-section of the fixing rib 700 can be circular, elliptical, etc.

[0135] Combination Figure 7 , Figure 9 and Figure 10 In some embodiments, the end plate 310 is provided with a curved cutout 312, and the portion enclosed by the cutout 312 is bent relative to the side of the end plate 310 facing the opening of the assembly groove 311 to form a snap 313.

[0136] For example, the cut 312 includes an arc-shaped segment and straight segments disposed on both sides of the arc-shaped segment, the two straight segments being opposite to each other and spaced apart. The cut 312 may be U-shaped.

[0137] With this design, the buckle 313 and the end plate 310 are integrally formed, resulting in a stable structure. The buckle can be formed by punching the notch 312 and then bending it, making the forming method and structure simple. Moreover, the buckle 313 is plate-shaped and inclined relative to the end plate 310, with the end of the buckle 313 that is further away from the end plate 310 facing the heating tube 410, which helps the heating tube 410 to be inserted into the buckle 313.

[0138] In some embodiments, the bending angle of the latch 313 is an acute angle. The bending angle of the latch 313 is the tilt angle of the latch 313 relative to the end plate 310, which is... Figure 10 In this configuration, along the first direction from the opening end of the buckle 313 to the connection end between the buckle 313 and the end plate 310, the distance between the buckle 313 and the end plate 310 gradually decreases along the third direction, and the restraining force on the fixing rib 700 gradually increases. This ensures the stability of the fixing rib 700 in the buckle 313 and the heating tube 410, thereby improving the stability of the fixing rib 700 in pressing the heating tube 410 into the assembly groove 311. Moreover, by adjusting the bending angle of the buckle 313, the restraining force of the buckle 313 on the fixing rib 700 can be adjusted, which is helpful for application to heating tubes 410 of different sizes.

[0139] Combination Figure 5 In some embodiments, multiple snap fasteners 313 are provided, and the multiple snap fasteners 313 are arranged at intervals along the second direction. This helps to improve the reliability of the fixing rib 700 engaging with the snap fasteners 313 and the heating tube 410, thereby improving the reliability of the fixing rib 700 pressing the heating tube 410 into the assembly groove 311.

[0140] The assembly slots 311 are provided in multiple ways and are arranged at intervals along the second direction. The number of assembly slots 311 is the same as the number of first tubes of the heating tube 410, so that the fixing rib 700 can press each first tube into the assembly slot 311, thereby improving the stability of the heater 400 assembled on the end plate 310.

[0141] Multiple assembly slots 311 and multiple clips 313 are arranged alternately along the second direction, so that the contact positions between the clips 313 and the fixing rib 700 and the contact positions between the fixing rib 700 and the heating tube 410 are staggered along the second direction. This helps the fixing rib 700 to deform and snap into the heating tube 410 and the clips 313, improving the ease of assembly of the fixing rib 700; it also helps to improve the stability and reliability of the assembly of the heating tube 410.

[0142] Combination Figure 5 , Figure 8 as well as Figure 11 In some possible assembly configurations, the first connecting portion 720 of the fixing rib 700 is inserted into the first connecting hole 314. In this case, the fixing rib 700 can move along... Figure 11 The heating element 410 hangs downwards along the Z-axis. The assembler rotates the fixing rib 700 approximately along the X-axis, from left to right, slightly deforming the fixing rib 700 to press it into the assembly groove 311 and engage it below the clip 313. Finally, the second connecting part 730 is inserted into the second connecting hole 315 to fix the heater 400 onto the end plate 310. The entire assembly process requires no tools, making assembly simple and convenient.
