DETAILED DESCRIPTION

[0062] In the description of the present invention, it should be noted that the terms "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0063] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0064] In the related technologies of washer-dryers, the method for cooling the hot and humid air discharged from the drying duct is generally to exchange heat with tap water and the hot and humid air to achieve cooling of the hot and humid air. This method generally uses the air duct as the heat exchange space, but the existing air duct cooling section generally has the problem of low heat exchange efficiency.

[0065] The main reason is that the contact area between the hot and humid air from the washing machine's drying duct and the tap water is small, and the air flow velocity is difficult to coordinate with the flow velocity of the tap water: if the fan speed is high (high wind speed), the tap water may be drawn into the fan and damage the fan; if the fan speed is low (low wind speed), there are disadvantages of small heat exchange area and insufficient heat exchange.

[0066] Based on the above background, the following embodiments are proposed:

[0067] Example 1:

[0068] like Figure 1 、 2 As shown, this embodiment provides a heat exchange component, including:

[0069] The first shell 1 is formed with:

[0070] Accommodating chamber 2,

[0071] The first port 3 is located on one side of the first shell.

[0072] The second port 4 is located on the other side of the first shell and opposite to the first port 3.

[0073] The third port 8 is a part of the first port 3 or a port independent of the first port 3.

[0074] The heat exchange fluid passage includes a second port 4, a receiving cavity 2 and a first port 3 for the heat exchange fluid to flow through in sequence.

[0075] The refrigerant fluid passage includes a third port 8, a receiving cavity 2, and a second port 4 for the refrigerant fluid to flow through in sequence;

[0076] The absorber 5 is disposed in the accommodating chamber 2 and is used for absorbing the refrigerant fluid and exchanging heat with the heat exchange fluid.

[0077] In this embodiment, the refrigerant fluid, i.e., tap water, enters the accommodating chamber 2 through the first port 3 and is absorbed by the absorbent 5. The absorbent 5 is made of a water-absorbing material. Preferably, the water-absorbing material is a sponge or pumice. When the heat exchange assembly is applied to the air duct of a washing machine, the heat exchange fluid, i.e., humid hot air, can flow in the air duct through the through hole 7. During the circulation of the humid hot air, the absorbent 5 cools the humid hot air in the through hole 7. The provision of the absorbent 5 increases the contact area between the tap water and the humid hot air, thereby improving the cooling efficiency of the tap water on the humid hot air.

[0078] At the same time, the absorbent member 5 is made of a water-absorbing material, such as a sponge or pumice stone, which can utilize the surface tension of water to make the water adhere to the absorbent member 5 and not easily escape and enter the fan under high wind speed conditions, thereby avoiding affecting the service life of the fan;

[0079] In addition, when this heat exchange component is used in the drying duct of a washing machine, the lint carried in the hot and humid air can be blocked at the lower side of the absorber 5. The setting of the absorber 5 can better absorb the tiny lint floating in the hot and humid air, reducing the impact of lint accumulation on other positions in the duct.

[0080] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0081] A third opening 8 is formed on one side of the first shell 1 in the longitudinal direction. The third opening 8 is located above the one side of the first shell 1 in the longitudinal direction and is part of the first opening 3, or the third opening 8 is located on the side wall of the one side of the first shell 1 in the longitudinal direction and is independent of the first opening 3.

[0082] The third port 8 is provided to guide the refrigerant into the accommodating chamber 2 for absorption by the absorber 5 to exchange heat with the heat exchange fluid.

[0083] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0084] The first housing 1 includes a first side wall 101 and a second side wall 102 in the length direction and a third side wall 103 and a fourth side wall 104 in the width direction. The first side wall 101 , the second side wall 102 , the third side wall 103 and the fourth side wall 104 surround and form a first opening 3 and a second opening 4 .

[0085] The first shell 1 is enclosed by a first side wall 101 , a second side wall 102 , a third side wall 103 and a fourth side wall 104 , and the first port 3 and the second port 4 formed therein facilitate the circulation of the refrigerant fluid and the heat exchange fluid.

[0086] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0087] The first housing 1 has a gradually narrowing trend from the first opening 3 to the second opening 4 .

[0088] The accommodating chamber 2 has a structure that is wide at the top and narrow at the bottom. The accommodating chamber 2 clamps the absorber 5 in the first shell 1 through the structure that is wide at the top and narrow at the bottom, thereby further firmly fixing the absorber 5 .

[0089] Optionally, in an implementation of this embodiment, as Figure 1 、 2 As shown,

[0090] The third side wall 103 has a first protrusion 25 protruding in a direction away from the fourth side wall 104, thereby forming a first refrigerant flow channel 22 protruding in a direction away from the fourth side wall 104 in the accommodating cavity 2. The first protrusion extends along the height direction of the third side wall, and a third port 8 belonging to a part of the first port 3 is formed above the first protrusion 25.

[0091] The absorber 5 has a second protrusion 26 on the side wall opposite to the third side wall, thereby forming a second refrigerant flow channel 20 outside the absorber 5 and the first refrigerant flow channel 22;

[0092] The absorber 5 is provided with a fourth port 9 connected to the second refrigerant flow channel 20. The fourth port 9 is opposite to the third port 8, and the two together form a port for the refrigerant fluid to enter. The second refrigerant flow channel 20 is located in the first refrigerant flow channel 22 and is in contact with the first refrigerant flow channel 22.

[0093] The fourth port 9 is provided for introducing the refrigerant fluid, i.e., tap water, into the accommodating chamber 2, so that the tap water can smoothly flow along the fourth port 9 and the second refrigerant flow channel 20 into the accommodating chamber 2 and be absorbed by the absorber 5;

[0094] The fourth port 9 and the second refrigerant flow channel 20 form a drainage component, which further guides the flowing tap water to the accommodating chamber 2. At the same time, the second refrigerant flow channel 20 and the first refrigerant flow channel 22 can be slidably matched, so that the absorber 5 can be easily extracted or reset from the first shell 1, and the replacement operation of the absorber 5 is more convenient.

[0095] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0096] One of the sliding portion 23 and the sliding rail 24 is formed on the top and / or bottom sides of the first side wall 101 and the second side wall 102 in the height direction.

[0097] The arrangement of the sliding portion 23 and the sliding rail 24 facilitates the connection between the first shell 1 and the flow channel of the heat exchange fluid.

[0098] Optionally, in an implementation of this embodiment, as Figure 1 、 2 As shown,

[0099] The absorbent member 5 has a through hole 7 that penetrates the absorbent member 5 along the height direction of the absorbent member 5; and / or,

[0100] The absorbent 5 fills the accommodating chamber 2; and / or,

[0101] The absorbent member 5 fills the accommodating chamber 2 but does not fill the portion of the accommodating chamber 2 below the third opening 8 .

[0102] The through hole 7 facilitates the passage of the heat exchange fluid through the absorber 5, thereby preventing the heat exchange fluid from being subjected to greater resistance from the absorber 5. The absorber 5 fills the accommodating chamber 2 and can fully absorb the refrigerant fluid entering the accommodating chamber 2, thereby achieving a higher heat exchange efficiency for the heat exchange fluid.

[0103] Optionally, in an implementation of this embodiment, as Figure 1 、 2 As shown,

[0104] A first clamping portion 10 is formed on the inner wall of the first shell 1, and a second clamping portion 21 is formed on the outer wall of the absorber 5. The absorber 5 and the first shell 1 are fixed in the accommodating cavity 2 through the clamping cooperation between the second clamping portion 21 and the first clamping portion 10.

[0105] The provision of the first clamping portion 10 and the second clamping portion 21 further enhances the firm fixing effect of the accommodating cavity 2 on the absorbent 5 .

[0106] Preferably, a hand hole 11 is provided on the first shell 1 near the first opening 3 , and the provision of the hand hole 11 facilitates the replacement operation of the absorber 5 .

[0107] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0108] The filter screen 6 is disposed in the accommodating chamber 2 . The filter screen 6 is closer to the second port 4 than the absorbent 5 .

[0109] The setting of the filter 6 can block large debris in advance, blocking the large debris on the lower side of the filter 6, while the smaller debris is blocked by the absorber 5, and mainly absorbs the tiny debris. This design makes the heat exchange component as a whole have a multi-level barrier to debris, thereby playing a better blocking effect. The setting of the filter 6 can also prevent large debris from getting stuck on the uneven surface of the absorber 5 with gaps and unevenness, making it difficult to clean.

[0110] At the same time, the arrangement of the filter screen 6 plays a certain supporting role on the absorber 5 , so that the absorber 5 as a whole is firmly fixed in the accommodating cavity 2 .

At the same time, a branch end of the tap water in the washing machine can enter the third refrigerant channel 15 through the refrigerant fluid inlet 18. During the flow of tap water in the third refrigerant channel 15, a part of the tap water will enter the heat exchange component. During the circulation of the humid hot air in the second shell 121, 122, it exchanges heat with the tap water in the third refrigerant channel 15 and the tap water in the heat exchange component, thereby forming multiple heat exchanges for the humid hot air, and the heat exchange channel as a whole has a higher heat exchange efficiency for the humid hot air.

The third refrigerant flow channel B152 is located outside the second flow channel section 122 and is connected to the heat exchange component. The end of the third refrigerant flow channel A151 near the second flow channel opening A14 serves as the refrigerant fluid inlet 18, and the end of the third refrigerant flow channel B152 near the second flow channel opening B13 serves as the refrigerant fluid outlet 19.

[0134] The heat exchange component is detachably sealed to the first flow channel section 121 and the second flow channel section 122 .

[0135] During the drying process of the washing machine, the exhausted hot and humid air enters the second flow channel section 122 through the second flow channel opening B13. At the same time, a branch end of the tap water in the washing machine can enter the third refrigerant flow channel 15 through the refrigerant fluid inlet 18. During the flow of the tap water in the third refrigerant flow channel 15, a part of the tap water will enter the heat exchange component. The specific inflow method is that the tap water flows out from the refrigerant fluid branch outlet into the fourth port 9 and flows along the third refrigerant flow channel 20 into the accommodating cavity of the first shell 1 and is absorbed by the absorber 5. During the circulation of the hot and humid air in the second flow channel section 122, it exchanges heat with the tap water at the bottom of the third refrigerant flow channel 15. The hot and humid air continues to circulate to the heat exchange component and exchanges heat with the tap water in the heat exchange component. Finally, the hot and humid air continues to circulate to the first flow channel section 121 and exchanges heat with the tap water at the top of the third refrigerant flow channel 15, thereby forming three heat exchanges for the hot and humid air. The heat exchange flow channel as a whole has a higher heat exchange efficiency for the hot and humid air.

[0136] Optionally, in an implementation of this embodiment, as Figure 4 As shown,

[0137] A first spray port 16 is provided near the second flow channel opening A14 of the first flow channel section 121, and the first spray port 16 faces the inside of the first flow channel section 121, and the first spray port 16 is provided with a first sprayer, and / or, a second spray port 17 is provided near the heat exchange component of the second flow channel section 122, and the second spray port 17 faces the lower side of the absorber 5 of the heat exchange component, and the second spray port 17 is provided with a second sprayer.

[0138] The first sprayer of the first spray port 16 is convenient for cleaning the interior of the first flow channel section 121 , and the second sprayer of the second spray port 17 is convenient for cleaning the absorber 5 and the filter screen 6 .

[0139] Example 3

[0140] This embodiment provides a washing machine, comprising: the heat exchange channel of the second embodiment;

[0141] The second flow channel opening B13 is connected to the air outlet of the drying flow channel, the second flow channel opening A14 is connected to the air inlet of the drying flow channel, and the refrigerant fluid inlet 18 is connected to the water outlet of the water flow channel.

[0142] During the drying process of the washing machine, the hot and humid air discharged from the drying flow channel enters the second flow channel section 122 through the second flow channel opening B13. At the same time, a branch end of the tap water in the water flow channel can enter the third refrigerant flow channel 15 through the refrigerant fluid inlet 18. During the flow of tap water in the third refrigerant flow channel 15, a part of the tap water will enter the heat exchange component. During the circulation of the hot and humid air in the second flow channel section 122, it exchanges heat with the tap water at the lower part of the third refrigerant flow channel 15. The hot and humid air continues to circulate to the heat exchange component and exchanges heat with the tap water in the heat exchange component. Finally, the hot and humid air continues to circulate to the first flow channel section 121 and exchanges heat with the tap water at the upper part of the third refrigerant flow channel 15, thereby forming three heat exchanges for the hot and humid air. The heat exchange flow channel as a whole has a higher heat exchange efficiency for the hot and humid air. The arrangement of the first sprayer and the second sprayer facilitates the cleaning of the inside of the first flow channel section 121, the absorber 5, the filter 6, etc. The tap water continuously overflows from the heat exchange component, and the continuously overflowing tap water is eventually discharged from the drying flow channel along the second flow channel opening B13.

[0143] Example 4

[0144] This embodiment provides a washing machine cleaning method, such as Figure 6 As shown, the washing machine cleaning method is applied to the washing machine in Example 3, and the washing machine includes a controller for executing the method, a second sprayer facing the lower side of the absorbent member 5, and a wind speed sensor for obtaining the wind speed value V entering the second flow channel opening B13;

[0145] The controller responds to the cleaning start instruction. The controller obtains the wind speed value V entering the through hole 7 through the wind speed sensor, and compares the wind speed value V with the preset wind speed value U. If V<U, the controller controls the second sprayer to work and spray the lower side of the absorbent 5. If V≥U, the cleaning is completed.

[0146] The controller responds to the cleaning start instruction. The controller measures the wind speed value V at the second flow channel B13 through the wind speed sensor and compares the wind speed value V with the preset wind speed value U. If V<U, the controller controls the second sprayer to work and spray the lower side of the absorbent 5. If V≥U, the cleaning is completed.

[0147] In this embodiment, the wind speed sensor acquires the wind speed value V after the wind speed stabilizes. The wind speed value V is then compared with a preset wind speed value U. If V < U, this indicates blockage in the absorber 5 and / or the filter 6. The second sprayer is then controlled to spray the underside of the absorber 5, thereby simultaneously spraying the absorber 5 and the filter 6 to clear the blockage. The wind speed value V is then acquired and compared with the preset wind speed value U repeatedly until V ≥ U, completing the cleaning process. The washing machine cleaning method of this embodiment maintains unobstructed heat exchange channels within the washing machine, thereby fully preparing for cooling the hot and humid air during the drying process. After cleaning is complete, the washing machine's electric heater can be activated to proceed with the normal drying process.

[0148] Optionally, in an implementation of this embodiment, the washing machine further includes a first sprayer directed toward the first flow channel section 121;

[0149] In response to the cleaning end instruction, the controller controls the first sprayer and the second sprayer to operate, the first sprayer sprays the inner side of the first flow channel section 121 , and the second sprayer sprays the lower side of the absorber 5 .

[0150] After cleaning, the first and second sprayers are controlled to spray the inner side of the second shell 121, 122 and the lower side of the absorber 5 for final supplementary cleaning, so as to keep the heat exchange flow channel in the washing machine unobstructed, and further prepare for the cooling of the humid hot air in the drying process.

[0151] Optionally, in an implementation of this embodiment, as Figure 6 As shown, after the second sprinkler has worked N times, if V < U is still the case, the fault reporting program is entered, where N is a set positive integer.

[0152] In this embodiment, N=5, and the second sprayer still cannot clear the heat exchange channel after working for 5 times, which proves that there is an abnormality in the heat exchange channel. The fault reporting program can issue a prompt to the user to remind the user to check the abnormality.

[0153] In summary, the ingenious design of the heat exchange components and heat exchange channels lies in:

[0154] First, during use of the heat exchange assembly, hot and humid air can flow through the through-holes in the air duct. During the circulation of the hot and humid air, the absorber cools the hot and humid air in the through-holes. The arrangement of the absorber increases the contact area between the tap water and the hot and humid air, thereby improving the cooling efficiency of the tap water on the hot and humid air.

[0155] At the same time, the absorbent is made of water-absorbing material, which can use the surface tension of water to make the water adhere to the absorbent, and it is not easy to break away and enter the fan under high wind speed conditions, avoiding affecting the service life of the fan;

[0156] In addition, the heat exchange component can block the lint carried in the hot and humid air at the lower side of the absorber. The setting of the absorber can better absorb the tiny lint floating in the hot and humid air, reducing the impact of lint accumulation on other positions in the air duct.

[0157] Second, the heat exchange channel is used for the circulation of humid hot air. The humid hot air enters the second shell through the second channel opening B. At the same time, tap water can enter the third refrigerant channel from the refrigerant fluid inlet. During the flow of tap water in the third refrigerant channel, a part of the tap water will enter the heat exchange component. During the circulation of the humid hot air in the second shell, it exchanges heat with the tap water in the third refrigerant channel and the tap water in the heat exchange component at the same time, thereby forming multiple heat exchanges for the humid hot air. The heat exchange channel as a whole has a higher heat exchange efficiency for the humid hot air.
