Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment technology, and in particular to a variable power drying and heating system and clothing processing device. Background Technology

[0002] Washing machines and washer-dryer combos are indispensable electrical appliances in people's daily lives, with multiple functions such as washing, rinsing, spin-drying, and drying.

[0003] To achieve the drying function, existing garment processing devices often have a drying heating system, which heats the airflow through an electric heater to create hot air for drying.

[0004] However, conventional drying and heating systems often only have one heating device, and the outlet air temperature is controlled by turning the heating device on and off. This results in the cessation of active heating. For example, the heating device is turned off when the outlet air temperature is higher than the high temperature threshold, and then turned on when the outlet air temperature is lower than the low temperature threshold. This makes it impossible for the existing drying and heating system to maintain stable heating of the airflow, resulting in significant fluctuations in the outlet air temperature, which in turn affects the drying effect. Utility Model Content

[0005] In view of this, the present invention aims to propose a variable power drying and heating system and a clothing processing device to solve the problem that the existing drying and heating system cannot maintain stable heating of the airflow at all times, resulting in significant fluctuations in the outlet air temperature and affecting the drying effect.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A variable power drying and heating system includes an air duct cavity, in which a heating component is disposed for heating the drying airflow. The heating component includes at least two heaters arranged sequentially along the flow direction of the drying airflow, and each heater can be turned on and off independently.

[0008] Furthermore, for any given heater, the heating power of the heater is different from that of the other heaters.

[0009] Furthermore, the drying and heating system is equipped with a temperature control protector on one side of the heating component, and the temperature control protector is connected to the control switch corresponding to each heater.

[0010] Furthermore, the drying and heating system includes a fan, an air duct component, and an air guide hood. One end of the air duct component is connected to the air outlet of the fan, and the other end of the air duct component is connected to the air guide hood. The air duct component has an air duct cavity.

[0011] Furthermore, the inner wall of the air duct component is provided with a support portion, and the heating component abuts or engages with the support portion.

[0012] Furthermore, the side wall of the air duct component is provided with a wire passage groove, through which the electrical connection wire of the heating component can pass and extend to the external space of the drying and heating system.

[0013] Furthermore, a protective plate is provided on the side of the air guide shroud near the cable tray. The protective plate is located on the outside of the air duct component, and the lower edge of the protective plate is lower than the bottom of the cable tray, or the lower edge of the protective plate is flush with the bottom of the cable tray.

[0014] Furthermore, the air duct component is provided with an assembly bayonet that communicates with the air duct cavity, and the drying and heating system includes a temperature control protector, which is engaged with the assembly bayonet.

[0015] A clothing handling device includes a drum body and a variable power drying and heating system. The drum body has a clothing inlet, and the drying and heating system has an air outlet located at the clothing inlet, which is capable of delivering drying airflow into the drum body.

[0016] Furthermore, on the projection along the central axis of the barrel, at least a portion of the projection surface of the air outlet coincides with the projection surface of the clothing inlet.

[0017] Compared with existing technologies, the variable power drying and heating system and clothing processing device of this utility model have the following advantages:

[0018] The variable power drying and heating system and clothing processing device described in this utility model, by setting at least two heaters in the air duct cavity, enables the drying and heating system to have at least three heating combination modes and can switch between different heating combination modes. On the one hand, it realizes the combination and switching of heating power, avoiding the simple form of "only controlling the on and off of the heating device to regulate the outlet air temperature" in the prior art. This ensures that the airflow can always be heated by a certain combination of heaters in the heating component during the drying process, and can always maintain active heating, ensuring stable heating of the airflow by the drying and heating system and avoiding unnecessary fluctuations in outlet air temperature. On the other hand, it enables the drying and heating system to provide a wider range of heating power, adapting to different models and improving its compatibility with different clothing processing devices.

[0019] Furthermore, since multiple heaters can operate simultaneously, the drying heating system of this application can provide greater heating power. This can effectively and quickly increase the outlet air temperature and the internal temperature of the drum during the initial operation of the drying mode, which helps to shorten the running time of the drying mode and improve drying efficiency.

[0027] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To address the problem in existing drying heating systems that cannot maintain stable heating of the airflow, resulting in significant fluctuations in outlet air temperature and affecting drying performance, this embodiment proposes a variable power drying heating system, as shown in the attached figure. Figure 1-4As shown, the drying and heating system 2 includes an air duct cavity 221, and a heating component 25 is provided in the air duct cavity 221 for heating the drying airflow. The heating component 25 includes at least two heaters arranged sequentially along the flow direction of the drying airflow, and each heater can be turned on and off independently.

[0031] That is, at least two heaters are arranged along the flow direction of the drying airflow, and are in an upstream-downstream relationship with respect to the airflow. The heating power of any two heaters can be the same or different. Preferably, the heating power of any one heater is different from the heating power of the other heaters.

[0032] Therefore, by providing at least two heaters in the air duct cavity 221, this application enables the drying heating system 2 to have at least three heating combination forms and to switch between different heating combination forms. On the one hand, it realizes the combination and switching of heating power, avoiding the simple form of "only controlling the on and off of the heating device to regulate the outlet air temperature" in the prior art. This ensures that during the drying process, the airflow can always be heated by one of the heater combination forms in the heating component 25, and can always maintain active heating, ensuring stable heating of the airflow by the drying heating system and avoiding unnecessary fluctuations in the outlet air temperature. On the other hand, it enables the drying heating system to provide a wider range of heating power, adapting to different models and improving its compatibility with different clothing processing devices.

[0033] Furthermore, since multiple heaters can operate simultaneously, the drying heating system of this application can provide greater heating power. This can effectively and quickly increase the outlet air temperature and the internal temperature of the drum 1 during the initial operation of the drying mode, which helps to shorten the running time of the drying mode and improve drying efficiency.

[0034] The drying and heating system 2 is equipped with a temperature control protector 26 on one side of the heating component 25. The temperature control protector 26 is electrically connected to the control switch (not shown) corresponding to each heater. Thus, in some extreme or abnormal situations, if the temperature of the heating component 25 becomes too high, the temperature control protector 26 can automatically cut off the control switch to avoid high-temperature accidents (such as component burnout, fire, etc.).

[0035] The drying and heating system 2 includes a fan 21, an air duct component 22, and an air guide hood 23. One end of the air duct component 22 is connected to the air outlet of the fan 21, and the other end of the air duct component 22 is connected to the air guide hood 23. The air duct component 22 has an air duct cavity 221. Preferably, the fan 21, the air duct component 22, and the air guide hood 23 are all sealed together. In particular, the air duct component 22 and the air guide hood 23 are snap-fitted together.

[0036] For the assembly of the heating component 25, a support portion is provided on the inner wall of the air duct component 22, and the heating component 25 abuts or snaps against the support portion, so that the heating component 25 can be reliably installed in the air duct cavity 221 of the air duct component 22.

[0037] Meanwhile, the side wall of the air duct component 22 is provided with a wire groove 224, and the electrical connection wire of the heating component 25 can pass through the wire groove 224 and extend to the external space of the drying heating system 2, so that the heating component 25 can be connected to the electrical control component.

[0038] A protective plate 231 is provided on the side of the air guide hood 23 near the wire passage 224. The protective plate 231 is located on the outside of the air duct component 22. The lower edge of the protective plate 231 is lower than or flush with the bottom of the wire passage 224. Thus, by providing the protective plate 231, on the one hand, the wire passage 224 can be shielded from the outside of the entire drying and heating system 2, preventing the heating component 25 from being directly seen or touched through the wire passage 224. On the other hand, the electrical connection wires extending outward from the heating component 25 can be protected, limited, or fixed.

[0039] The air duct component 22 is provided with an assembly bayonet 225 that communicates with the air duct cavity 221. The temperature control protector 26 is engaged with the assembly bayonet 225, so that the temperature control protector 26 can be independently installed on the air duct component 22 and can detect the operating status of the heating component 25.

[0040] The air duct component 22 and the air guide shroud 23 together form an air outlet 24; of course, an air outlet 24 can also be opened on the air duct component 22 or the air guide shroud 23.

[0041] The air duct component 22 is provided with a diverter 222 on the side near the air outlet 24. This diverter disperses the airflow about to exit the air outlet 24, allowing the airflow to enter the barrel 1 in a more dispersed and turbulent state. Furthermore, the air duct component 22 can also engage or abut against the air guide shroud 23 through the diverter 222, improving the assembly reliability between the air duct component 22 and the air guide shroud 23. This also helps support the air guide shroud 23, improving the stress distribution of the drying and heating system 2 near the air outlet 24. For example: refer to the attached diagram. Figure 3 , 4 The diverting part 222 is provided with a snap-fit ​​protrusion on the side near the air guide shroud 23, and the air guide shroud 23 is provided with a snap-fit ​​hole, and the snap-fit ​​protrusion snaps into the snap-fit ​​hole.

[0042] Based on the drying and heating system 2, this application also proposes a clothing handling device, including a tub body 1 and a drying and heating system 2. One end of the tub body 1 has a conventional open structure, referred to as the clothing inlet 12. The drying and heating system 2 has an air outlet 24 located at the clothing inlet 12, which can deliver drying airflow into the tub body 1. Accordingly, the clothing handling device of this application can be any clothing handling device, such as a conventional drum washing machine, a top-loading washing machine, or a washer-dryer combo, all of which can include the drying and heating system 2 described in this embodiment.

[0043] On the projection along the central axis of the barrel 1, at least a portion of the projection surface of the air outlet 24 coincides with the projection surface of the clothes inlet 12, so that the drying airflow can smoothly and directly enter the interior of the barrel 1 from the clothes inlet 12.

[0044] Preferably, the air outlet side 223 of the air duct component 22 is provided with an arc-shaped edge, so that the air outlet 24 can be formed to correspond to the circle of the clothes inlet 12, so that the drying airflow can enter the interior of the drum 1 entirely from the clothes inlet 12. The arc-shaped edge has a transition flange, which is parallel to the central axis of the drum 1 and extends towards the interior of the drum 1. This, in conjunction with the air guide hood 23, makes the air outlet 24 parallel to the central axis of the drum 1.

[0045] Furthermore, this application does not impose too many restrictions on the tub body 1. It can be a conventional inner and outer double tub structure of a top-loading washing machine or a front-loading washing machine, or it can be a single tub structure (such as an early twin-tub top-loading washing machine). Accordingly, both the inner and outer double tub structure and the single tub structure are conventional technologies and will not be described in detail.

[0046] Preferably, the tub body 1 includes an outer tub and an inner tub, and the drying and heating system 2 is connected to the outer wall of the outer tub; and / or, the washing equipment includes a shell and an inner liner, the inner liner being disposed between the shell and the tub body 1, and the drying and heating system 2 being connected to the inner liner.

[0047] Correspondingly, for the conventional inner and outer double-tub structure of pulsator washing machines, a balance ring 11 is often set on the top of the inner tub, which will not be elaborated here.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
