Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a clothing processing device and a drying control method for the clothing processing device. Background Technology

[0002] As living standards improve, people have higher requirements for the quality of home appliances. Clothing processing equipment is an important auxiliary tool for family life. In addition to traditional washing and cleaning, the ability to quickly and efficiently dry clothes with fresh air has become an important indicator for measuring the performance and competitiveness of washing machines.

[0003] Most current drum-type garment drying equipment heats air in a heater before it enters the drum to absorb moisture from the clothes, turning it into humid, hot air. This humid air then enters a condenser where the water vapor is condensed. The air, now free of water vapor, returns to the heater, and this process is repeated until the clothes are dry. This cycle is completely isolated from the outside environment, resulting in poor air circulation and unpleasant odors on the clothes. Summary of the Invention

[0020] In the above technical solution, the intermediate channel includes a first connecting end that communicates with the intake channel and a second connecting end that communicates with the exhaust channel;

[0021] In the height direction of the condenser box, the first connecting end is set higher than the second connecting end, wherein the distance between the condensate outlet and the first connecting end is greater than the distance between the condensate outlet and the second connecting end.

[0022] In the above technical solution, the intermediate channel is constructed as a curved surface, and in the height direction of the condenser box, the intermediate channel extends downward from the first connecting end to the second connecting end.

Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0047] Most existing clothing drying equipment heats air in a heater before it enters the drum to absorb moisture from the clothes, turning it into hot, humid air. This humid air then enters a condenser where the water vapor is condensed. The air, now free of water vapor, returns to the heater, and this process is repeated until the clothes are dry. This cycle is completely isolated from the outside environment, resulting in poor air circulation and unpleasant odors in the clothes. In this embodiment of the invention, by opening a fresh air inlet on the fan, the drying efficiency of the clothing processing equipment can be improved. Simultaneously, a condenser box is installed, allowing the hot, humid air from the clothing processing equipment to be condensed before being discharged to the outside. This balances the air pressure inside the drum, further improving drying efficiency and preventing condensation in the water tank of the clothing processing equipment. Furthermore, because fresh air is introduced during drying, the temperature rise inside the clothing processing drum slows down in the early stages of drying. To further improve drying efficiency and achieve water conservation, this embodiment of the invention includes a temperature sensor to detect the temperature inside the clothing processing drum. The sensor can control the water intake or stop intake of the condenser box based on the temperature value inside the drum, thereby improving drying efficiency while achieving water conservation.

[0048] The following is in conjunction with the appendix Figure 1-3 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0049] Example

[0050] like Figure 1 and Figure 2 As shown, this embodiment proposes a garment processing device, including:

[0051] The garment processing tube includes an outer tube 1 and an inner tube 2 pivotally disposed in the outer tube 1, with an internal condensation air duct 11 formed between the outer tube 1 and the inner tube 2.

[0052] The external condenser duct is connected to the internal condenser duct 11, and the outlet is connected to the inner cylinder 1.

[0053] Fan 3 is connected to the external condenser duct and is used to drive the airflow in the external condenser duct to circulate. Fan 3 includes a fresh air inlet, which is used to introduce fresh air into the external condenser duct when the fan is running; that is, the fan 3 in this embodiment of the invention is a double suction fan.

[0054] The inner rear wall of the outer cylinder 2 has a first air outlet and a second air outlet distributed vertically. The first air outlet is connected to the fan 3 through the air outlet pipe 8, and the second air outlet is connected to the condenser air duct outside the cylinder.

[0055] The condenser box 4 has an air inlet 41 and an exhaust outlet 42. The air inlet 41 is connected to the condensing air duct 11 inside the cylinder, and the exhaust outlet 42 is connected to the external environment of the clothing processing equipment. The condenser box 4 also has a water inlet 43 and a drain outlet 44. The drain outlet 44 is connected to the condensing air duct 11 inside the cylinder and / or the condensing air duct outside the cylinder. Water discharged into the condenser box 4 through the water inlet 43 can condense the gas entering the condenser box 4 and then be discharged from the drain outlet 44.

[0056] Temperature sensor 7 is used to detect the temperature in the garment processing drum;

[0057] The controller controls the water inlet 43 to supply water based on the temperature in the clothes processing drum when fresh air is introduced by the fan 3.

[0058] In this embodiment of the invention, by opening a fresh air inlet (not shown in the figure) on the fan 3, the drying efficiency of the clothing processing equipment can be improved. Simultaneously, a condenser box 4 is provided, which allows the hot and humid air in the clothing processing drum to be discharged into the condenser box 4 for condensation before being discharged to the outside. This balances the air pressure inside the drum, further improving drying efficiency and preventing condensation in the water box of the clothing processing equipment. Furthermore, because fresh air is introduced during drying, the temperature rise inside the clothing processing drum slows down in the early stages of drying. To further improve drying efficiency and achieve water conservation, this embodiment of the invention includes a temperature sensor for detecting the temperature inside the clothing processing drum. The sensor can control the water intake or stop intake of the condenser box based on the temperature value inside the drum, thereby improving drying efficiency while achieving water conservation.

[0059] It is worth noting that in this embodiment of the invention, the fresh air inlet is set on the fan 3, that is, the fan 3 in this embodiment of the invention is a double suction fan with double air inlets. In this way, the introduced fresh air can be fully mixed in the condenser duct outside the cylinder before being discharged into the clothes processing cylinder, thereby avoiding the appearance of two different temperature airflows, one cold and one hot, in the clothes processing cylinder, thus improving the accuracy of the temperature sensor when detecting the temperature inside the cylinder.

[0060] If the fresh air inlet is not located on the fan, but is instead connected to the inner cylinder 2 via a separate vent, the outside fresh air will mix with the heated drying airflow in the inner cylinder 1. This will result in two airflows, one cold and one hot, in the inner cylinder 2. Consequently, the temperature data detected by the temperature sensor inside the cylinder will deviate significantly, leading to an unoptimal timing for water intake. This may prevent the system from achieving both improved drying efficiency and water conservation.

[0061] Specifically, such as Figure 2 As shown, the condenser box is provided with an air outlet channel, which connects the air inlet 41 and the exhaust port 42.

[0062] The condenser box is also equipped with a drain pipe 45, which has a water inlet end and a drain end. The water inlet end is connected to the air outlet channel, and the drain end is connected to the drain outlet 44 of the condenser box 4 and / or the condenser air duct 1 inside the cylinder and / or the condenser air duct outside the cylinder.

[0063] When condensate enters through inlet 41, the condensate entering the condenser box 4 from inlet 41 can fall onto the surface of the air outlet channel and exchange heat with the humid and hot air in the air outlet channel. The humid and hot air in the air outlet channel is condensed into dry and cold air and discharged into the outside environment through outlet 42. The condensate after the humid and hot air is condensed can be discharged into outlet 42 through drain pipe 45 and enter the inner condenser duct 11 and / or outer condenser duct through drain outlet. Alternatively, the condensate after the humid and hot air is condensed can also be directly discharged into the inner condenser duct 11 and / or outer condenser duct through drain pipe 45.

[0064] However, relatively speaking, the preferred option is, such as Figure 2 As shown, the condensate generated in the air outlet duct is discharged into the drain outlet 42 through the drain pipe 45, and then into the condensate air duct 11 inside the cylinder through the drain outlet 42.

[0065] Furthermore, such as Figure 2 As shown, the air outlet duct includes an air intake duct 46 connected to the air inlet 41, an exhaust duct 47 connected to the exhaust outlet 42, and a plurality of intermediate ducts 48 connecting the air intake duct 46 and the exhaust duct 47.

[0066] Each of the intermediate channels 48 is equipped with a condensate outlet, which is connected to the drain pipe 45.

[0067] In this embodiment of the invention, by setting multiple intermediate channels 48, the high-pressure, humid, and hot gas entering the condenser box can be fully depressurized, preventing excessive pressure from impacting the condenser box 4. Simultaneously, setting multiple intermediate channels 48 can also improve the condensation effect on the humid and hot air. Preferably, as... Figure 2 As shown, there are three intermediate channels 48.

[0068] Furthermore, such as Figure 2 As shown, the intake channel 46 and the exhaust channel 47 are distributed on both sides of the length direction of the condenser box 4, and the intake channel 46 and the exhaust channel 47 are arranged along the height direction of the condenser box 4. Multiple intermediate channels 48 are arranged along the height direction of the condenser box 4.

[0069] The air inlet 41 of the condenser box 4 is connected to the bottom of the air inlet channel 46, the exhaust port 42 of the condenser box 4 is connected to the top of the exhaust channel 47, the water inlet 43 of the condenser box 4 is located at the top of the condenser box 4, and the drain port 44 of the condenser box 4 is located at the bottom of the condenser box 3.

[0070] In this embodiment of the invention, by setting the air inlet 41 of the condenser box 4 at the bottom of the air inlet channel 46 and the exhaust port 42 at the top of the exhaust channel 47, the flow path and flow time of the airflow in the condenser box 4 can be extended, thereby enabling sufficient condensation of the humid and hot gas entering the condenser box 4.

[0071] It is worth noting that, in order to improve the condensation effect of the multiple intermediate channels 48 on the humid and hot gas, in this embodiment of the invention, the multiple intermediate channels 48 are spaced apart in the width direction of the condensation box 3.

[0072] A water spraying device is connected to the water inlet 43, which is used to spray water onto multiple intermediate air ducts 48. Preferably, the water spraying device can be a nozzle installed at the water inlet 43, which allows the water flowing out of the water inlet 43 to be sprayed onto the multiple intermediate channels 48 in a mist form.

[0073] In this embodiment of the invention, by arranging multiple intermediate channels 48 at intervals in the width direction of the condensation box 4, and simultaneously providing a water spray device at the water inlet 43, each of the multiple intermediate channels 48 can come into contact with water when water is discharged from the water inlet 43, thereby improving the condensation effect on humid and hot gas.

[0074] It should be noted that since multiple intermediate channels 48 are spaced apart in the width direction of the condenser box 4, the lengths of the intake channels 46 and exhaust channels 47 located on both sides of the intermediate channels 48 in the width direction of the condenser box 4 are also correspondingly longer. On the one hand, this ensures that all the intermediate channels 48 can communicate with it; on the other hand, it increases the volume of the intake channels 46 and exhaust channels 47, thus providing sufficient space for pressure relief when the airflow enters the condenser box 4, preventing excessive gas pressure from causing a large impact on the condenser box 4. In other words, this embodiment of the invention makes full use of the internal space of the condenser box 4, improving both the condensation effect and the pressure relief effect of the airflow.

[0075] In any of the above embodiments, such as Figure 2As shown, the intermediate channel 48 includes a first connecting end that communicates with the intake channel 46 and a second connecting end that communicates with the exhaust channel 47.

[0076] In the height direction of the condenser box 4, the first connecting end is set higher than the second connecting end, wherein the distance between the condensate outlet and the first connecting end is greater than the distance between the condensate outlet and the second connecting end.

[0077] In this embodiment of the invention, by setting the first connecting end of the intermediate channel 48 higher than the second connecting end, it is easier for the condensate in the intermediate channel 48 to be discharged.

[0078] Specifically, such as Figure 2 As shown, the intermediate channel is constructed as a curved surface, and in the height direction of the condenser box 4, the intermediate channel 48 extends downward from the first connecting end to the second connecting end.

[0079] In this embodiment of the invention, by setting the intermediate channel 48 as a curved surface, the flow effect of condensate in the intermediate channel 48 can be improved, and condensate can be prevented from accumulating in the intermediate channel 48.

[0080] In any of the above embodiments, such as Figure 1 As shown, the external condensing air duct includes a condensing air duct 12 and a heating air duct 13. The fan 3 is connected to the condensing air duct 12 and the heating air duct 13. The air inlet of the condensing air duct 12 is connected to the outer cylinder 1, and the air outlet of the heating air duct 13 is connected to the inner cylinder 2.

[0081] The garment processing equipment also includes a vent pipe 5, one end of which is connected to the outer cylinder 1 and the other end is connected to the air inlet 41 of the condenser box 4;

[0082] The garment processing equipment also includes a housing 6, with a condenser box 4 fixedly installed on the inner wall of the housing 6;

[0083] The garment processing equipment also includes a water injection pipe for injecting water into the condenser duct 12 and the condenser duct 11 inside the cylinder.

[0084] Preferably, the aforementioned garment processing equipment is a washer-dryer.

[0085] To further understand the working principle of the clothing processing device in the embodiments of the present invention, the following is combined with... Figure 1 and Figure 2 Please provide a detailed explanation:

[0086] like Figure 1 As shown, a condenser box is added to the upper part of the back panel of the garment processing equipment. The air inlet 41 of the condenser box 4 is connected to the outer cylinder 1 through the vent pipe 5. A temperature sensor is provided near the condenser box 4 to monitor the temperature inside the vent pipe.

[0087] When the fan 3 with fresh air inlet is turned on, fresh air enters the inner cylinder 2 through the outer condenser duct and comes into contact with the clothes to form a humid and hot airflow. Part of the humid and hot airflow enters the outer condenser duct for condensation, and part of it condenses directly in the inner condenser duct. Ribs are provided on the rear inner wall of the outer cylinder 1. The condensate entering from the water inlet pipe can flow through the ribs. The humid and hot airflow entering the inner condenser duct 11 contacts the rear wall of the outer cylinder 1 and condenses. The water vapor in it is dehumidified, and the air with the water vapor removed flows back to the fan 3. Another part enters the condenser box 4 through the vent pipe 5 on the outer cylinder 1.

[0088] like Figure 2 As shown, when the hot and humid airflow enters through the air inlet 41 of the condenser box 4, it is condensed through multiple intermediate channels 48. The intermediate channels 48 are designed with a certain curvature and a condensate outlet is opened at the end of the pipe. The purpose is to allow the condensate on the inner wall of the intermediate channel 48 to be smoothly discharged into the intermediate channel 48 by gravity, and first flow into the drain outlet 44 at the bottom of the condenser box 4, and finally discharge into the cylinder for condensation inside the cylinder again.

[0089] It is worth noting that, due to the introduction of fresh air, the temperature inside the drum rises more slowly in the early stages of drying. In order to further improve drying efficiency and save water, appropriate logic control needs to be adopted for the water inlet of the condenser box.

[0090] Based on this, the second aspect of the present invention provides a method such as Figure 3 The drying control method for the garment processing equipment shown is applied to the aforementioned garment processing equipment, and the control method includes:

[0091] During the drying process, the temperature inside the clothes processing drum is obtained, and the water intake of the condenser box is controlled or stopped based on the temperature inside the clothes processing drum.

[0092] Specifically, methods for controlling the water inlet of the condenser box to enter or stop entering water based on the temperature in the garment processing drum include:

[0093] When the temperature in the clothes processing drum is lower than the first preset temperature value, the water inlet is controlled to stop water intake;

[0094] When the temperature in the clothes processing drum is greater than or equal to the first preset temperature value, water is introduced through the inlet.

[0095] In the initial stage of drying, the temperature inside the clothes processing drum is low, so the condenser box 4 does not need to be filled with water. Water is only needed when the temperature inside the drum is greater than or equal to the first preset temperature value.

[0096] Specifically, when the temperature in the garment processing drum is greater than or equal to the first preset temperature value, the methods for controlling water intake at the inlet include:

[0097] Control the water inlet to allow water to enter intermittently until the drying process is complete.

[0098] When the temperature in the clothes processing drum exceeds a certain value, the water inlet is controlled to intermittently supply water to the condenser box 4, thereby saving water resources while ensuring the condensation effect.

[0099] More specifically, methods for controlling the intermittent water intake at the inlet until the drying process ends include:

[0100] When the temperature in the clothes processing drum is greater than or equal to the first preset temperature value, the water inlet is controlled to intermittently supply water at the first interval until the temperature in the clothes processing drum reaches the second preset temperature value.

[0101] When the temperature in the clothes processing drum reaches the second preset temperature value, the water inlet is controlled to intermittently supply water at the second interval until the drying program ends.

[0102] Wherein the first preset temperature value is less than the second preset temperature value, and the first interval duration is less than the second interval duration.

[0103] It is worth noting that when the temperature in the clothes processing drum reaches the second preset temperature value, the drying stage has been reached. At this stage, the humidity of the hot and humid gas in the clothes processing drum is relatively low, so water can be introduced at longer intervals, thereby saving water resources while ensuring the condensation effect.

[0104] Furthermore, when the temperature in the garment processing drum reaches the second preset temperature value, the fan and the heating device in the heating duct are controlled to shut off. That is, when the drying program reaches the end of the drying process, the fan 3 and the heating device must be turned off.

[0105] It should also be noted that after the fan 3 and heating device are turned off at the end of the drying process, although there is no circulating air flow in the clothes processing drum, the air pressure in the clothes processing drum is still relatively high. It is necessary to exhaust the air to the outside to achieve the purpose of balancing the air pressure. At this time, the gas is still in a high temperature state. In order to reduce the probability of the exhaust gas generating steam, water spraying is still required, but the time interval is longer than before.
