Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, specifically, it relates to a clothing processing device and its control method. Background Technology

[0002] A clothes dryer is a household cleaning appliance that uses electric heating to evaporate and dry the moisture in washed clothes.

[0003] A washer-dryer combo is a new type of intelligent clothing processing equipment that combines washing, spinning, and drying functions into one, based on a fully automatic clothing processing device with the addition of a drying function.

[0004] Whether it's a dryer or a washer-dryer combo, the drying process mainly involves blowing hot, dry air into the drum to remove moisture from the clothes, thus achieving the purpose of drying. This type of clothing processing equipment is particularly suitable for the winters in the north and the humid, rainy seasons in the south where clothes are difficult to dry.

[0005] Drum-type washer-dryer combos, whether floor-standing or wall-mounted, are becoming increasingly popular with users, and the industry is paying more and more attention to the development of drying performance.

[0006] Chinese patent application CN201811015088.9 discloses a wall-mounted clothing handling device, comprising: a tub assembly having a receiving cavity for placing clothing, and the tub assembly also having a first opening and a second opening, both of which communicate with the receiving cavity; a drying tunnel assembly disposed outside the tub assembly, the drying tunnel assembly including an air inlet and an air outlet, the air outlet communicating with the first opening; a condenser assembly disposed outside the tub assembly, the condenser assembly including a condenser shell, the condenser shell having a drain outlet communicating with the second opening and an exhaust outlet communicating with the air inlet; and an air pipe, one end of the air pipe communicating with the condenser shell, and the other end of the air pipe communicating with the external space of the clothing handling device.

[0007] The aforementioned garment processing device is a water-cooled drum washer-dryer combo. During the drying process, the humid drying air that has exchanged heat with the garments needs to be dehumidified. The cooling source used for dehumidification can be cooling water or cooling air, and the supply method of the cooling source can be continuous or timed. However, the impact of the cooling source flow rate on the cooling effect is not considered.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clothing processing device. By setting a temperature detection unit at the air outlet to detect the temperature of the humid and hot air, the flow rate of the refrigerant can be adjusted according to the temperature of the humid and hot air. This not only makes the drying parameters more accurate, but also allows for better control of the drying performance.

[0010] Another object of the present invention is to provide a control method for a garment processing device, which is applied to the garment processing device described above.

[0011] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0014] A drying device, one end of which is connected to the air outlet and the other end of which is connected to the interior of the clothing processing tub;

[0015] A first temperature detection unit is installed inside the clothing processing drum near the air outlet. The controller controls the flow rate of the refrigerant in the drying device based on the temperature of the humid air at the air outlet detected by the first temperature detection unit.

[0016] Furthermore, the drying apparatus includes:

[0020] Furthermore, the air outlet is located on the side wall of the clothing processing tub;

[0021] A mounting groove with a receiving chamber is provided at the connection between the bottom wall and the side wall of the clothing processing bucket. The receiving chamber is connected to the inside of the clothing processing bucket, and the detection end of the first temperature detection unit is located in the receiving chamber.

[0022] Furthermore, the mounting groove is a recess formed by the outward indentation of the bottom wall of the clothing processing tub;

[0023] The groove has a mounting hole on its side wall, and the first temperature detection unit is installed in the mounting hole. The detection end of the first temperature detection unit is located in the receiving cavity of the groove.

[0024] Furthermore, the sidewall of the groove is provided with a clearance groove for avoiding the sealing structure between the first temperature detection unit and the mounting hole.

[0025] Furthermore, the distance between the mounting groove on the edge of the bottom wall of the clothing processing tub and the center of the air outlet is minimized.

[0026] Furthermore, a second temperature detection unit is provided inside the condensation channel;

[0027] The controller controls the flow rate of refrigerant in the condensing channel based on the temperature of the humid air at the air outlet detected by the first temperature detection unit and the temperature of the air in the condensing channel detected by the second temperature detection unit.

[0029] Furthermore, a humidity detection unit is provided inside the condensation channel;

[0030] The controller controls the flow rate of refrigerant in the condensing channel based on the temperature of the humid air at the air outlet detected by the first temperature detection unit and the humidity of the air in the condensing channel detected by the humidity detection unit.

[0031] A control method for a garment processing device, applied to the garment processing device as described above, includes the following steps:

[0032] Obtain the temperature of the humid air at the air outlet of the garment processing drum;

[0033] The refrigerant flow rate is adjusted according to the temperature of the humid air; the higher the temperature of the humid air, the greater the refrigerant flow rate.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0036] 2. The present invention provides a groove on the bottom wall of the clothing processing tub for installing the first temperature detection unit, which avoids occupying the internal space of the clothing processing tub.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0050] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting this invention.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] like Figures 1 to 6 As shown, the present invention provides a garment processing device and its control method. The garment processing device includes a garment processing tub 10, which is provided with an air outlet 11 for discharging hot and humid air from within the garment processing tub 10. Specifically, for a washer-dryer combo, the garment processing tub 10 includes an outer tub and an inner tub rotatably disposed within the outer tub, and the air outlet 11 is located on the outer tub.

[0053] See Figures 1 to 3 The garment processing equipment also includes a drying device, one end of which is connected to the air outlet 11, and the other end is connected to the interior of the garment processing drum 10. The humid and hot air inside the garment processing drum 10 enters the drying device through the air outlet 11, and after being processed by condensation and heating, it is transformed into dry and hot air and then circulated back into the interior of the garment processing drum 10 to dry the clothes.

[0054] The present invention provides a first temperature detection unit 12 for detecting the temperature of the humid air at the air outlet 11 in the clothing processing drum 10. The first temperature detection unit 12 is communicatively connected to the controller of the clothing processing equipment, so that the controller controls the flow rate of the refrigerant in the drying device according to the temperature of the humid air at the air outlet 11.

[0055] In detail, when the first temperature detection unit 12 detects that the temperature of the humid air at the air outlet 11 is high, the flow rate of the refrigerant in the condensation channel is increased to ensure the condensation effect of the refrigerant on the humid air; when the first temperature detection unit 12 detects that the temperature of the humid air at the air outlet 11 is relatively low, the flow rate of the refrigerant in the condensation channel is appropriately reduced to save refrigerant consumption while ensuring the condensation effect.

[0056] The drying device in the above scheme includes a heating component 20 and a condensing component 30. The heating component 20 includes a heating channel 21, within which a heater for heating air can be installed. One end of the heating channel 21 is connected to the clothes handling drum 10, introducing heated air into the drum 10 to dry the clothes. The condensing component 30 includes a condensing channel, one end of which is connected to the air outlet 11 of the clothes handling drum 10, and the other end is connected to the other end of the heating channel 21. Moisture in the clothes evaporates into water vapor under the action of the heated air, mixing with the air to become humid air. This humid air enters the condensing channel through the air outlet 11. The condensing channel contains a refrigerant whose flow direction is opposite to that of the humid air. Heat exchange occurs between the humid air and the refrigerant within the condensing channel, pre-cooling the water vapor in the humid air into condensate, thus turning the humid air into dry, cold air. The dry, cold air then re-enters the heating channel 21 for reheating and is then circulated back into the clothes handling drum 10 to dry the clothes.

[0057] It is evident that controlling the refrigerant flow rate is of great significance for improving the condensation effect on humid and hot air within the condensation channel.

[0058] The present invention provides a first temperature detection unit 12 at the air outlet 11 of the clothing treatment tank 10, which can accurately determine the temperature of the humid and hot air entering the condensation channel. Based on the temperature, the flow rate of the refrigerant in the condensation channel can be precisely adjusted, which can not only ensure the condensation effect, but also save water.

[0059] In some embodiments of the present invention, such as Figure 2 As shown, the air outlet 11 is disposed on the side wall of the clothing processing tub 10; an installation groove with a receiving chamber is provided at the connection between the bottom wall of the clothing processing tub 10 and the side wall of the clothing processing tub 10, the receiving chamber is connected to the interior of the clothing processing tub 10, and the detection end of the first temperature detection unit 12 is disposed in the receiving chamber.

[0060] In detail, for wall-mounted clothing processing equipment, the overall size of the machine is relatively small. Therefore, the heating component 20 in the drying device is usually set above the clothing processing drum 10, while the condensing component 30 is usually set on the side wall of the clothing processing drum 10. This allows the axial dimension of the clothing processing drum 10 to be as large as possible, thereby increasing the processing capacity of the wall-mounted clothing processing equipment.

[0061] Therefore, for the wall-mounted clothing processing equipment, the present invention sets the air outlet 11 on the side wall of the clothing processing tub 10. Since the axial dimension of the clothing processing tub 10 is small, a mounting groove for installing the first temperature sensor is provided at the connection between the bottom wall and the side wall of the clothing processing tub 10, so that the temperature of the humid air detected by the first temperature sensor can reflect the temperature of the humid air at the air outlet 11.

[0062] In the preferred scheme, such as Figure 4 As shown, the distance between the mounting groove on the edge of the bottom wall of the clothing processing tub 10 and the center of the air outlet 11 is the smallest.

[0063] In some embodiments of the present invention, the mounting groove is a groove 13 formed by the outward protrusion of the bottom wall of the clothing processing tub 10; a mounting hole 15 is provided on the side wall of the groove 13, the first temperature detection unit 12 is installed in the mounting hole 15, and the detection end of the first temperature detection unit 12 is located in the receiving cavity of the groove 13.

[0064] It is understood that, regarding the bottom wall of the clothing processing tub 10, when viewed from inside the clothing processing tub 10, the mounting groove is a recessed groove 13, and when viewed from outside the clothing processing tub 10, the mounting groove is a protruding protrusion. The groove 13 described in this invention is relative to the inside of the clothing processing tub 10.

[0065] In the above solution, a groove 13 for installing the first temperature detection unit 12 is provided on the bottom wall of the clothing processing tub 10, which can avoid occupying the internal space of the clothing processing tub 10.

[0066] In further proposals, such as Figure 6 As shown, the side wall of the groove 13 is provided with a clearance groove 14 for avoiding the sealing structure between the first temperature detection unit 12 and the mounting hole 15, so that only the wiring end of the first temperature detection unit 12 extends out of the clearance groove 14, which can avoid mechanical interference between the first temperature detection unit 12 and other structures of the clothing processing equipment.

[0067] In some embodiments of the present invention, a second temperature detection unit is provided in the condensation channel; the controller controls the flow rate of refrigerant in the condensation channel based on the temperature of the humid air at the air outlet 11 detected by the first temperature detection unit 12 and the temperature of the air in the condensation channel detected by the second temperature detection unit.

[0068] In further proposals, such as Figure 3 As shown, the second temperature detection unit is located at one end where the condensation channel is connected to the heating channel 21.

[0069] In the above scheme, by setting a second temperature detection unit in the condensation channel, the temperature of the humid air after condensation by the refrigerant can be obtained. Combined with the temperature of the humid air before condensation by the refrigerant obtained by the first temperature detection unit 12, the condensation effect of the refrigerant on the humid air can be obtained more accurately, and the adjustment of the refrigerant flow rate can be more targeted.

[0070] In some other embodiments of the present invention, a humidity detection unit is provided in the condensation channel; the controller controls the flow rate of the refrigerant in the condensation channel based on the temperature of the humid air at the air outlet 11 detected by the first temperature detection unit 12 and the humidity of the air in the condensation channel detected by the humidity detection unit.

[0071] In the above scheme, by setting a humidity detection unit in the condensation channel, the humidity of the humid air after the condensation of the refrigerant can be obtained. Combined with the temperature of the humid air before being condensed by the refrigerant obtained by the first temperature detection unit 12, the condensation effect of the refrigerant on the humid air can be obtained more accurately, and the adjustment of the refrigerant flow rate can be more targeted.

[0072] The refrigerant in this invention can be either cooling water or cooling air.

[0073] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, a refrigerant conduit 33 is provided on the outer wall of the condensing channel to input refrigerant into the condensing channel. The intersection line 34 between the inner wall surface of the condensing channel and the refrigerant conduit 33 is elliptical, and the area defined by the intersection line 34 constitutes the refrigerant inlet 35 of the condensing channel.

[0074] This invention addresses the issue by installing a refrigerant conduit 33 on the outer wall of the condensation channel and tilting the refrigerant conduit 33. This creates an elliptical intersection line 34 between the refrigerant conduit 33 and the inner wall of the condensation channel. Figure 4 As shown, the refrigerant does not enter the condensation channel in a single flow direction, but rather forms a dispersed flow direction on the elliptical surface. Therefore, the refrigerant completes the first flow distribution as it enters, increasing the heat and mass exchange rate between the refrigerant and the humid air, thereby improving the condensation efficiency of the refrigerant on the humid air and thus improving the drying efficiency of the clothing processing equipment.

[0075] The condensation channel includes a condenser body 31 and a condenser cover 32. A refrigerant conduit 33 is disposed on the outer wall of the condenser cover 32. The intersection line 34 between the inner wall surface of the condenser cover 32 and the refrigerant conduit 33 is elliptical. The area defined by the intersection line 34 constitutes the refrigerant inlet 35 of the condensation channel, and the axis of the refrigerant conduit 33 extends laterally.

[0076] The refrigerant preferred in this invention is tap water. Air has low solubility in tap water, and using tap water as the refrigerant offers advantages such as reliable source and simple recovery. Furthermore, the water inlet component of the wall-mounted clothing processing device is generally located below the clothing processing tank 10, and the air outlet 11 of the clothing processing tank 10 is generally located at a lower position, while the refrigerant inlet 35 is located at a higher position. Thus, under the action of lift, the hot and humid air moves upwards, while under the action of gravity, the refrigerant moves downwards. During this cross-convection process, the refrigerant condenses the water vapor in the hot and humid air into condensate, and the condensed air is discharged from the air outlet 11 of the condensation channel.

[0077] The present invention sets the refrigerant conduit 33 on the outer wall of the condenser cover 32, and sets the axis of the refrigerant conduit 33 to extend laterally. On the one hand, it facilitates the connection between the refrigerant conduit 33 and the water inlet component of the clothing treatment equipment. On the other hand, when the refrigerant enters the condensation channel through the refrigerant conduit 33, the refrigerant can be fully dispersed in the lateral direction, increasing the area on which the refrigerant moves from top to bottom.

[0078] In a preferred embodiment of the present invention, the ratio of the major axis to the minor axis of the intersection line 34 ranges from 4:1 to 6:1.

[0079] In detail, the shape of the intersection line 34 is elliptical, and the ratio of the major axis to the minor axis of the ellipse is between 4:1 and 6:1, making the ellipse as a whole slender shape, which further allows the refrigerant to be fully dispersed in the lateral direction and increases the area on which the refrigerant moves from top to bottom.

[0080] In addition, the ratio between the major axis of the ellipse and the lateral dimension of the condenser cover 32 should be between 2:5 and 3:5.

[0081] In some embodiments of the present invention, in order to further guide the flow direction of the refrigerant in the condensation channel, a guide plate 36 protruding from the inner wall surface is provided on the inner wall surface of the condenser cover 32, and the guide plate 36 intersects with the extension of the major axis of the intersection line 34.

[0082] Detailed, such as Figure 4 As shown, after the refrigerant enters the condensing channel through the elliptical refrigerant inlet 35, although the elliptical structure facilitates the first refrigerant distribution, if the refrigerant's entry velocity is high, a large amount of refrigerant will move along the major axis of the elliptical structure, which is detrimental to refrigerant dispersion. Therefore, this invention provides a guide plate 36 downstream of the refrigerant inlet 35. When the refrigerant flows along the major axis of the elliptical structure, it impacts the guide plate 36, and the flow direction of the refrigerant is changed by the obstruction of the guide plate 36, thus achieving a second refrigerant distribution.

[0083] The guide plate 36 can be a flat plate structure. The flat plate structure of the guide plate 36 has a reflective effect on the refrigerant, thereby changing the flow direction of the refrigerant.

[0084] However, in a preferred embodiment of the present invention, the guide plate 36 has an arc-shaped structure, and the convex surface of the guide plate 36 faces the refrigerant inlet 35. The convex structure of the guide plate 36 has a dispersing effect on the refrigerant, further enhancing the contact area between the refrigerant and the humid air.

[0085] In a further embodiment, a refrigerant redistributor 37 is provided on the inner wall surface of the condenser cover 32, and the tangent of the end of the guide plate 36 from which the refrigerant detaches intersects with the area covered by the inlet of the refrigerant redistributor 37.

[0086] In a preferred embodiment, the intersection point between the guide plate 36 and the extension of the major axis of the intersection line 34 is located upstream of the inflection point of the arc-shaped guide plate 36.

[0087] In detail, to further enhance the condensation effect of the refrigerant on humid and hot air, this invention provides a refrigerant redistributor 37 capable of performing a third refrigerant distribution on the inner wall of the condenser cover 32. The refrigerant disperses and flows in all directions of the condensation channel under the action of the guide plate 36, but some refrigerant still flows along the inner wall of the condenser cover 32 under the action of the guide plate 36. Therefore, in order to ensure that this portion of refrigerant can fully cover the inner wall of the condenser cover 32, a refrigerant redistributor 37 is provided downstream of the guide plate 36.

[0088] It should be noted that the tangent of the end of the refrigerant that is detached on the guide plate 36 should fall into the inlet of the refrigerant redistributor 37 in order to redistribute this portion of refrigerant.

[0089] In some embodiments of the present invention, such as Figure 4 As shown, in order to prevent the condenser cover 32 from deforming due to a large temperature gradient in the condensation channel, a reinforcing rib 321 is provided on the outer wall of the condenser cover 32.

[0090] In detail, the reinforcing ribs 321 include transverse reinforcing ribs 321, longitudinal reinforcing ribs 321 and arc-shaped reinforcing ribs 321, and each reinforcing rib 321 is arranged crosswise on the outer wall surface of the condenser cover 32.

[0091] The control method for the garment processing equipment provided by this invention, applied to the garment processing equipment described above, specifically includes the following steps:

[0092] Obtain the temperature of the humid air at the air outlet 11 of the clothing processing drum 10;

[0093] The refrigerant flow rate is adjusted according to the temperature of the humid air; the higher the temperature of the humid air, the greater the refrigerant flow rate.

[0094] The present invention provides a first temperature detection unit 12 at the air outlet 11 of the clothing treatment tank 10, which can accurately determine the temperature of the humid and hot air entering the condensation channel. Based on the temperature, the flow rate of the refrigerant in the condensation channel can be precisely adjusted, which can not only ensure the condensation effect, but also save water.

[0095] The first temperature detection unit 12, the second temperature detection unit, and the humidity detection unit mentioned above can be sensors or other electronic components that can perform their functions; this invention does not limit them.

[0096] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
