Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, and in particular to a filtering component, a supporting structure and clothing processing equipment. Background Art

[0002] During the process of drying clothes in the clothing processing equipment, the clothes need to be continuously turned over in the drum. Due to the constant friction between the drum and the clothes, lint is generated. In order to prevent the lint from entering the circulating air duct of the dryer and causing clogging of the evaporator, a filter assembly is generally required in the circulating air duct to intercept the lint generated during the drying process.

[0003] The filter of the heat pump dryer is generally arranged directly below the supporting front shell. The filter assembly is detachably placed in the channel of the supporting front shell. The filter assembly structure is generally a net bag structure. The high-temperature and high-humidity air in the circulating air duct enters the interior of the filter assembly from above the filter along with the lint, and then passes through the filter into the evaporator. Therefore, the lint in the circulating air duct is intercepted inside the filter assembly.

[0036] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0037] At present, the filter net in the prior art is in the form of a net bag. When filtering air, impurities such as hair scraps are intercepted inside the net bag, which is inconvenient when cleaning the filter net. The embodiment of the utility model proposes a filter assembly, a support structure and a clothing processing device, wherein the filter assembly is constructed in a narrow upper and wide lower form. When the filter assembly is installed in the air duct, the hair fluff entrained in the air can be intercepted on the surface of the filter assembly, and will not accumulate inside the filter assembly. When the user takes out the filter assembly, it is not necessary to open the filter assembly to easily clean the hair fluff on the surface of the filter. At the same time, under the combined action of gravity and wind force, the hair fluff accumulates to the root of the filter assembly, which increases the air permeability and improves the filtering performance.

[0038] The following is combined with Figure 1 -Attached Figure 4 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0039] Example

[0040] like Figure 1-Figure 4 As shown, in a first aspect of this embodiment, a filter assembly is provided, which is used to be installed in an air duct of a clothes processing device, and the filter assembly includes:

[0041] The filter bracket 1 is a cavity structure with a narrow upper part and a wide lower part in a longitudinal section, an air outlet 11 communicating with the cavity is formed at the bottom of the filter bracket 1, and a filter mounting surface 12 is formed at the side of the filter bracket, that is, the filter mounting surface 12 that makes the filter bracket 1 narrow at the top and wide at the bottom is formed at the side of the filter bracket, and the filter mounting surface 12 has a filtering structure communicating with the cavity;

[0042] When the filter assembly is installed in the air duct, the top of the filter bracket 1 faces the air inlet direction of the air duct, and the bottom faces the air outlet direction of the air duct.

[0043] The filter assembly in the embodiment of the utility model is constructed to be narrow at the top and wide at the bottom. When the filter assembly is installed in the air duct, the narrow end face of the filter assembly is arranged toward the air inlet end of the air duct, and the wide end face of the filter assembly is arranged toward the air outlet end of the air duct. In this way, when the air flow flows in the air duct, the filter assembly can intercept the fluff entrained in the air flow on the surface of the filter assembly without accumulating inside the filter assembly. When the user takes out the filter mesh assembly, the fluff on the surface of the filter mesh can be easily cleaned without opening the filter mesh assembly. Moreover, since the mounting surface of the filter mesh is inclined, the fluff intercepted on the mounting surface of the filter mesh accumulates toward the root of the filter mesh assembly under the combined action of gravity and wind force, thereby increasing the air permeability of the filter mesh assembly and improving the filtering performance.

[0044] Further, such as Figure 1 and Figure 2 As shown, the filter support has two filter mounting surfaces 12 that are opposite and inclined;

[0045] Each filter screen installation surface 12 is provided with a filtering structure.

[0046] When the airflow blows from the narrow end face of the filter assembly to the filter assembly, the airflow will be divided into two parts by the narrow end face of the filter assembly, and enter the cavity inside the filter assembly after being filtered by the filtering structures on the two filter mounting surfaces 12 respectively, and finally discharged through the air outlet at the bottom of the filter assembly.

[0047] In any of the above-mentioned embodiments, an air inlet 121 communicating with the cavity is formed on the filter screen installation surface 12 , and the filtering structure includes a filter screen 2 installed on the filter screen installation surface 12 and adapted to the air inlet 121 .

[0049] Further, such as Figure 1 and Figure 2 As shown, the cavity structure inside the filter bracket 1 includes a first cavity and a second cavity that are independent of each other, the air inlet 121 includes a first air inlet and a second air inlet formed on the filter mounting surface 12, and the air outlet 11 includes a first air outlet and a second air outlet arranged at the bottom of the filter bracket 1

[0050] The first air inlet and the first air outlet are connected to the first cavity, and the second air inlet and the second air outlet are connected to the second cavity.

[0051] In any of the above-mentioned embodiments, a collecting groove 3 is provided on the filter installation surface 12 , and the collecting groove 3 is located below the air inlet 121 .

[0052] In the embodiment of the utility model, when the fluff on the filter installation surface accumulates to a certain extent below the air inlet 121, the fluff on the top will fall into the collection groove 3 below the air inlet under the action of gravity and wind, thereby facilitating the collection of the fluff.

[0053] In any of the above embodiments, if Figure 1 and Figure 2 As shown, preferably, the filter support 1 is designed as a right-standing triangle structure or an isosceles trapezoidal structure.

[0054] In any of the above embodiments, if Figure 1 and Figure 3 As shown, the filter assembly further includes a support base 4, and the filter support 1 is located on the support base 4;

[0055] A vent 41 is formed on the bracket base 4;

[0056] When the filter support 1 is located on the support base 4, the air outlet 11 of the filter support 1 is connected to the vent 41;

[0057] A sealing structure 13 is also provided on the side of the filter support 1. Preferably, the sealing structure 13 is a sealing ring;

[0058] The sealing structure 13 is designed to fit with the inner periphery of the ventilation hole 41 on the support base 4 when the filter support 1 is seated on the support base 4;

[0059] A reinforcing rib 42 is provided in the vent 41 to divide the vent 41 into a first vent and a second vent;

[0060] The first vent is communicated with the first air outlet, and the second vent is communicated with the second air outlet.

[0061] In the embodiment of the utility model, a bracket base 4 is provided at the bottom of the filter bracket 1, so that the filter bracket 1 is conveniently installed in the air duct. At the same time, since the side of the filter bracket 1 is also provided with a sealing structure sealed with the bracket base 4, when the filter bracket 1 is installed on the bracket base 4, it can be ensured that the airflow flowing out from the bottom of the filter bracket 1 is completely discharged from the vent 41 on the bracket base 4 without leaking from the connection position between the two.

[0062] In any of the above embodiments, if Figure 3 As shown, in order to improve the stability of the filter bracket 1 and the bracket base 4 when they are matched, a boss 43 is provided on the inner periphery of the vent 31 on the bracket base 4 in the embodiment of the utility model, and the boss 43 is used to abut the bottom of the filter bracket 1 when the filter bracket 1 is located on the bracket base 4.

[0063] A second aspect of the present embodiment provides a support structure for installation in a clothes processing device. An air duct 7 is formed on the support structure, and the above-mentioned filter assembly is arranged in the air duct.

[0064] like Figure 4 As shown, the support structure includes a support front shell 5 and a bracket assembly 6 which are sealed and connected, a clothing delivery port is formed on the bracket assembly 6, and an air duct 7 is formed at the bottom of the clothing delivery port;

[0065] The air duct 7 has an air inlet end and an air outlet end. The top of the filter bracket 1 in the filter assembly is communicated with the air inlet end of the air duct 7 , and the bottom is communicated with the air outlet end of the air duct 7 .

[0066] A third aspect of the present embodiment provides a clothing processing device, which includes the above-mentioned supporting structure. Preferably, the above-mentioned clothing processing device is a heat pump dryer.

[0067] In order to make the working principle of the filter assembly in the embodiment of the utility model clearer, the following Figure 1-Figure 4 To explain in detail:

[0068] like Figure 1-Figure 4 As shown, the structure of the filter bracket 1 is designed to be a right triangle structure with a small top and a large bottom, and a bottom width of: the top width is ≥4cm and is symmetrical. The filter 2 is arranged on the left and right sides of the filter bracket 1. The bottom of the filter bracket 1 is an opening structure with an air outlet 11. A reinforcing rib 42 is arranged in the middle of the bracket base 4 to prevent the filter bracket from being deformed inwardly. A sealing strip installation groove is arranged at the root of the filter bracket 1 for installing the sealing strip, and a lint collection groove is arranged above the sealing strip for collecting lint falling during the drying process.

[0069] A bracket assembly 6 is provided on the support front shell 5 for installing the bracket filter assembly. A sealing groove is provided around the bracket assembly 6. The bracket assembly 6 is fastened to the support front shell 5 by screws to ensure that the circulating airflow does not pass through the assembly gap between the support assembly 6 and the support front shell 5; a sealing surface that seals with the filter assembly is provided on the inner side of the bracket assembly 6. When the filter assembly is installed on the bracket assembly 6, it can ensure that the two are sealed and airtight.

[0070] When the user puts the clothes into the drum and starts drying using a specific program, the filter assembly needs to be inserted into the supporting front shell 5, the drum starts to rotate and the fan is turned on to drive the wind into the drum from the small holes in the rear flange of the drum. At this time, the wind flows from the rear end of the drum to the front end and enters the front filter assembly of the supporting front shell 5. Since other positions are in a sealed state, the high-temperature and high-humidity air with fluff is forced to pass only through the filter screens 2 on the left and right sides, and then pass out from the air outlet 11 at the bottom, so that the fluff is intercepted on the outer surface of the filter assembly. As the drying time goes by, the fluff accumulated on the surface of the filter assembly will naturally fall into the collecting groove 3 set at the root of the filter bracket 1 due to its own gravity and wind force. This can greatly alleviate the problem of fluff clogging the filter in the late stage of drying and causing a decrease in drying efficiency; after the drying is completed, the user only needs to take out the filter assembly and gently scrape off the fluff on the surface of the filter screen 2, which greatly reduces the difficulty of cleaning the filter screen 2.
