[0049] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0050] In the relevant technology, washing machine drying technologies mainly fall into two categories: condensing drying and heat pump drying. Condensing drying has been used in washing machines for many years and is relatively mature, but its performance and effectiveness are less than satisfactory. Problems include long drying times, poor drying results, and excessively high drying temperatures that can damage clothing. Heat pump technology offers a higher energy efficiency ratio than condensing technology, but it is relatively expensive, has a complex structure, and requires a high level of space. This makes it difficult to implement within standard washing machine dimensions, significantly impacting performance.

[0051] Based on the above technical problems, the present application provides a drying module and electrical equipment, providing a drying technical solution with a simple structure and good drying effect.

[0052] Figure 1 shows a schematic structural diagram of a drying module in one or more embodiments of the present application, Figure 2 Shown Figure 1 Explosion diagram of . Figure 1 as well as Figure 2 The drying module provided in this application includes a shell 1, an air induction member 2, a heat exchanger 3 and a heater 4, wherein the shell 1 is provided with a drying channel 5, and the air induction member 2, the heat exchanger 3 and the heater 4 are arranged in the drying channel 5 in sequence from upstream to downstream along the air flow direction in the drying channel.

[0053] In the drying module provided in the present application, under the action of the air induction member 2, the humid hot air flow is introduced into the drying channel 5. Under the action of the refrigerant of the heat exchanger 3, the humid hot air flow introduced into the drying channel 5 undergoes a phase change and is condensed into liquid water. The condensed humid hot gas becomes a dry cold air flow. After being heated by the heater 4, the temperature increases and becomes dry hot air. The dry hot air flows out of the drying channel 5 to achieve the drying function.

[0054] The drying module provided in the present application only includes an air induction member 2, a heat exchanger 3 and a heater 4. It has a simple structure, small size requirements, and low requirements for spatial layout. It can adjust the output power of the heater 4 according to the temperature requirements to output a heating temperature that meets the requirements, thereby avoiding the phenomenon of damaging clothes due to excessive drying temperature, thereby ensuring drying performance and drying effect, shortening drying time, and reducing costs.

[0055] Combine Figure 1 as well as Figure 2In some embodiments, the housing 1 is further provided with an air inlet 13, an air outlet 14, and a drain 15, which are connected to the drying tunnel 5. The drain 15 is provided below the heat exchanger 3. The hot and humid air flow is introduced into the drying tunnel 5 through the air inlet 13. Under the action of the refrigerant in the heat exchanger 3, the hot and humid air flow introduced into the drying tunnel 5 undergoes a phase change and condenses into liquid water. Under the action of gravity, the liquid water is drawn out through the drain 15 below the heat exchanger 3. The condensed hot and humid gas becomes dry cold air flow. After being heated by the heater 4, the temperature is increased and it becomes dry hot air. It then flows out of the drying tunnel 5 through the air outlet 14 to achieve the drying function.

[0056] Figure 3 Shown Figure 1 The structural diagram of the shell in Figure 4 Shown Figure 3 A schematic structural diagram of the first shell in FIG. Figure 5 Shown Figure 3 Schematic diagram of the structure of the second shell. Figure 2-Figure 5 In some embodiments, the shell 1 may include a first shell 11 and a second shell 12. The first shell 11 may be located at the top and the second shell 12 may be located at the bottom. The cross-sections of the first shell 11 and the second shell 12 are roughly U-shaped. The open sides of the two are spliced ​​together to form a shell 1 with a hollow cavity. The hollow cavity of the shell 1 is configured as a drying tunnel 5. A seal 113 may be provided at the junction of the first shell 11 and the second shell 12 to ensure the sealing effect of the drying tunnel.

[0057] Combine Figure 5 In some embodiments, the drying tunnel 5 may include a volute section 51, and the air inducing member 2 is arranged in the volute section 51 to increase the air intake volume of the moist hot air under the same output power, and has the characteristics of high efficiency, reliability and energy saving.

[0058] Combine Figure 4 In some embodiments, an accommodating recess 16 is provided at the top of the first housing 11 constituting the volute section 51 . Figure 6 Shown Figure 1 The structural diagram of the induced draft piece in Figure 2 、 Figure 4 as well as Figure 6 The air inducing member 2 includes a drive motor 21 and an impeller 22. The drive motor 21 is mounted in the receiving recess 16 so that the drive motor 21 is approximately flush with the surface of the first housing 11. The output shaft of the drive motor 21 passes through the bottom of the receiving recess 16 and enters the volute section 51. The impeller 22 is connected to the output shaft of the drive motor 21. When the drive motor 21 is controlled to operate, the impeller 22 rotates synchronously to introduce the moist hot air flow into the volute section 51 of the drying tunnel 5 through the air inlet portion 13 and discharge it from the outlet of the volute section 51.

[0059] In some embodiments, the circumferential clearance of the impeller 22 is wrapped around the outer circumferential surface of the accommodating recess 16 to reduce the space occupied by the air inducing member 2 in the housing 1 and further reduce the overall size of the drying module.

[0060] In some embodiments, the drive motor 21 and impeller 22 of the air induced member 2 shown in the present application can be arranged on different axes and driven intermittently through a transmission belt / gear. The transmission ratio can be set to be greater than 1, so that it can be appropriately adjusted according to different working conditions to achieve better air intake effect while reducing costs.

[0061] Combine Figure 5 In some embodiments, a vent 17 is provided at the bottom of the second housing 12 forming the volute section 51. The vent 17 can be configured as the aforementioned air inlet 13. The vent 17 is located below the impeller 22 and can be circular, matching the size and shape of the impeller 22. In other embodiments, the vent 17 can be provided in a grid pattern at the bottom of the second housing 12 forming the volute section 51, thereby providing both an air intake function and a certain filtering function.

[0062] Combine Figure 5 In some embodiments, the drying tunnel 5 may further include a heat exchange section 52 , which is connected to the air outlet of the volute section 51 . The heat exchange section 52 may be a substantially straight section, and the heat exchanger 3 is assembled in the heat exchange section 52 of the drying tunnel 5 .

[0063] Figure 7 Shown Figure 1 Schematic diagram of the heat exchanger in the structure. Figure 1 、 Figure 2 as well as Figure 7 In some embodiments, the heat exchanger 3 functions to maintain a stable temperature within a certain range in the drying tunnel 5 where the heat exchanger 3 is mounted. This temperature is significantly lower than the temperature of the hot, humid gas flowing through it, thereby providing a low-temperature environment. The heat exchanger 3 can be a conventional fin-type water-cooled heat exchanger, a mixed-flow fin heat exchanger, a blade heat pipe heat exchanger, or any other heat exchanger capable of providing gas heat exchange, without limitation. The heat exchanger 3 is provided with a refrigerant inlet and outlet protruding from the housing 1 to continuously provide energy to maintain a low temperature.

[0064] Figure 8 Shown Figure 5 A structural diagram from another perspective, Figure 9 Shown Figure 8 A magnified schematic diagram, Figure 10 Shown Figure 5 Schematic diagram of the top view. Figure 5 、 Figures 8-10In some embodiments, the heat exchanger 3 can be suspended in the drying tunnel 5, so that the heat exchanger 3 and the bottom of the drying tunnel 5 can be constructed in a water storage space 38 to accommodate liquid water formed by condensation of the hot and humid air flow under the action of the refrigerant in the heat exchanger 3. The water storage space 38 can be connected to the drainage portion 15 to drain the liquid water it contains through the drainage portion 15.

[0065] Combine Figure 5 、 Figures 8-10 In some embodiments, a plurality of support ribs 31 may be provided at intervals on the bottom of the drying tunnel 5 (i.e., the bottom of the second shell 12). The heat exchanger 3 is supported on the plurality of support ribs 31, so that the heat exchanger 3 is suspended in the drying tunnel 5. The plurality of support ribs 31 may be integrally formed at the bottom of the second shell 12 to provide sufficient support strength.

[0066] Combine Figure 5 、 Figures 8-10 In some embodiments, multiple support ribs 31 are spaced apart along the airflow direction (i.e., the length of the heat exchange section 52), and each support rib 31 is provided with a first mounting groove 32 at both ends. Accordingly, mounting plates 33 can be provided at both ends of the heat exchanger 3. These mounting plates 33 are embedded in the first mounting grooves 32 at the same ends to securely mount the heat exchanger 3 in the drying tunnel 5.

[0067] Combine Figure 5 、 Figures 8-10 In some embodiments, the side wall of the drying tunnel 5 may be provided with a sealing rib 34, which is connected to the end of the supporting rib 31. When the heat exchanger 3 is assembled in place, the sealing rib 34 is in contact with the mounting plate 33 of the heat exchanger 3 to prevent the hot and humid air flow from passing through the gap between the heat exchanger 3 and the side wall of the drying tunnel 5, thereby ensuring the heat exchange effect of the hot and humid air flow.

[0068] Combine Figure 5 、 Figures 8-10 In some embodiments, two support ribs 31 may be provided opposite to each other along the airflow direction, and the same ends of the two support ribs 31 are connected by a connecting rib 35 to form the above-mentioned water storage space 38.

[0069] Combine Figure 5 、 Figures 8-10 In some embodiments, the connecting rib 35 can be integrally formed at the bottom of the first shell 11, and both ends of the connecting rib 35 can be connected to the bottom of the first mounting groove 32 of the support rib 31. The connecting rib 35 and the bottom of the first mounting groove 32 are in a flush posture, and the mounting plate 33 at the end of the heat exchanger 3 abuts against the connecting rib 35 to further improve the support effect on the heat exchanger 3.

[0070] Combine Figure 5 、 Figures 8-10In some embodiments, at least one reinforcing rib 36 may be provided between the connecting rib 35 and the side wall of the first shell 11 , and the reinforcing rib 36 is also integrally formed at the bottom of the first shell 11 to enhance the supporting strength of the connecting rib 35 .

[0071] Combine Figure 5 、 Figures 8-10 In some embodiments, at least one connecting rib 35 is provided with a water outlet 37, and the drainage portion 15 can be provided at the bottom of the side of the drying tunnel 5. The drainage portion 15 and the water outlet 37 are connected to discharge the liquid water contained in the water space 38.

[0072] Combine Figure 5 、 Figures 8-10 In some embodiments, a guide recess 18 may be provided at the bottom of the drying tunnel 5. A portion of the guide recess 18 is provided at the bottom of the water holding space 38, and another portion of the guide recess 18 extends to the side of the drying tunnel 5 to communicate with the drainage portion 15. The guide recess 18 may be configured as a water guide channel of the water holding space 38 to quickly guide the liquid water in the water holding space 38 to the drainage portion 15 for discharge.

[0073] In some embodiments, the depth of the guide recess 18 may be gradually deepened toward the side of the drying tunnel 5 , so that the liquid water can be quickly discharged through the drainage portion 15 , thereby preventing the liquid water from being stored and retained in the water storage space 38 .

[0074] Combine Figure 1 as well as Figure 5 In some embodiments, a drain pipe 6 may be connected to the bottom of the side of the drying tunnel 5 (i.e., the side wall of the second shell 12). The drain pipe 6 may be configured as a drain portion 15. The drain pipe 6 may be connected to a pipeline to lead the liquid water in the water storage space 38 out to a corresponding occasion through the pipeline.

[0075] Combine Figure 1 as well as Figure 5 In some embodiments, the drain pipe 6 can be arranged obliquely downward to prevent liquid water from flowing back into the water storage space 38.

[0076] In some embodiments, the refrigerant inlet and the refrigerant outlet of the heat exchanger 3 may be disposed on both sides of the drying tunnel 5 so that the refrigerant has a sufficient travel distance to improve the condensation effect.

[0077] Combine Figure 2 In some embodiments, a flow equalizing member 8 may be further provided in the drying tunnel 5 . Figure 11 Shown Figure 1 The structural diagram of the current equalizer in Figure 2 as well as Figure 11A flow equalizer 8 is positioned between the heat exchanger 3 and the heater 4. It is provided with multiple vents 81, each with a uniform diameter, or at least some of the vents 81 with varying diameters. The flow equalizer 8 regulates parameters such as airflow pressure and velocity, ensuring uniform distribution of airflow through the heat exchanger 3 and even entry into the heat exchanger 3, generating dry, hot air with a uniform temperature and achieving optimal heat exchange. If the drying tunnel 5 is properly laid out, a flow equalizer is no longer necessary.

[0078] Combine Figure 9 In some embodiments, second mounting grooves 110 may be provided on two opposing sidewalls of the second housing 12 constituting the drying tunnel 5, with both ends of the flow equalizer 8 being mounted in the corresponding second mounting grooves 110. In a specific implementation, the tops of the second mounting grooves 110 are open, allowing the flow equalizer 8 to be pushed into the second mounting grooves 110 from above and below, and then secured within the drying tunnel 5 by the stopper of the first housing 11.

[0079] Combine Figure 9 In some embodiments, mounting protrusions 19 are provided on two opposite side walls of the drying tunnel 5. The mounting protrusions 19 can be integrally formed on two opposite side walls of the second shell 12, and the above-mentioned second mounting grooves 110 are provided on the opposite sides of the two mounting protrusions 19.

[0080] In other embodiments, the second mounting groove 110 may also be directly provided on two opposite side walls of the drying tunnel 5, which is not limited here; or, the flow equalizer 8 may also be assembled in the drying tunnel 5 by welding or integral molding, which is not limited here.

[0081] Combine Figure 5 In some embodiments, the drying tunnel 5 may further include a heating section 53, which may be a substantially straight segment. The heater 4 is mounted within the heating section 53 of the drying tunnel 5. The volute section 51, the heat exchange section 52, and the heating section 53 are sequentially connected to form the drying tunnel 5. The flow equalizer 8 is disposed between the heat exchange section 52 and the heating section 53 to ensure that the pressure and flow rate of the airflow passing through the equalizer plate 8 are uniform, and thus the airflow evenly enters the heater 4, thereby improving the heater's heating effect on the airflow.

[0082] In some embodiments, the function of the heater 4 is to continuously heat the gas flowing therethrough to significantly increase its temperature. The heater 4 may be a tubular heating element, a heating wire, or a heating plate, which is not limited here.

[0083] Figure 12 Shown Figure 8 The enlarged schematic diagram of point B, combined with Figure 9 as well as Figure 12Under the condition that the heater 4 is a tubular heating element, at least one mounting block 111 is provided at the bottom of the drying tunnel 5 (i.e., the bottom of the heating section 53).

The tube body of the heater 4 is assembled in the third mounting groove 112 on the mounting block 111, so that the heater 4 is assembled in the heating section 53 of the drying tunnel 5.

[0084] In some embodiments, there may be only one mounting block 111 , or more mounting blocks 111 may be provided depending on the number of tubes of the heater 4 , which is not limited here.

[0085] Combine Figure 1 as well as Figure 2 In some embodiments, the drying module may further include a thermostat 9. The drying tunnel 5 is provided with a thermostat 9 at the location where the heater 4 is installed (i.e., the side wall of the heating section 53) to protect the heater 4 and the drying tunnel 5 from overheating.

[0086] Combine Figure 1 as well as Figure 2 In some embodiments, the drying module may further include a temperature sensor 7, which is installed on the side wall of the drying tunnel 5. The temperature sensor 7 is provided upstream and / or downstream of the heat exchanger 3 and upstream and / or downstream of the heater 4 to detect the air flow temperature in the drying tunnel 5, so as to control the heating power of the heater 4 and the refrigerant flow of the heat exchanger 3 to output a drying temperature that meets the requirements.

[0087] Combine Figure 1 、 Figure 2 as well as Figure 5 In some embodiments, the drying tunnel module 5 may further include an exhaust pipe 10, which is connected to the end of the heating section 53 to be configured as an air outlet 14. The exhaust pipe 10 can be integrally formed at the end of the second shell 12 and arranged obliquely downward to guide the heated airflow to the area to be dried.

[0088] Based on the above-mentioned drying module, the present application also provides an electrical device, which includes the above-mentioned drying module.

[0089] The electrical equipment equipped with the above-mentioned drying module can avoid the phenomenon of clothes being damaged by excessively high drying temperatures, thereby ensuring the drying performance and drying effect, shortening the drying time, and reducing costs, and has good practicality.

The air inlet 13 of the drying module is connected to the air outlet end of the drum, and the air outlet 14 of the drying module is connected to the air inlet end of the drum. When the washing machine is working, under the action of the air induction part 2 of the drying module, the humid hot air flow in the drum is introduced into the drying channel 5 through the air inlet 13. The humid hot air flow introduced into the drying channel 5 undergoes a phase change under the action of the refrigerant in the heat exchanger 3 and is condensed into liquid water. Under the action of gravity, the liquid water is discharged through the drainage part 15 below the heat exchanger 3. The condensed humid hot gas becomes dry cold air flow. After being heated by the heater 4, the temperature increases and it becomes dry hot air. It flows out of the drying channel 5 through the air outlet 14 and is transported to the drum. This cycle is repeated to dry the clothes in the drum.
