Description

Technical Field

[0001] This invention belongs to the field of dryer technology, specifically relating to a clothing processing device. Background Technology

[0002] Washer-dryer combos that use tap water condensation for drying have lower drying efficiency compared to heat pump washing machines, and each drying cycle takes longer, typically 4-5 hours at full load. Users find this time too long and have a poor experience.

[0003] Washer-dryer combos use tap water to condense hot, humid air, so tap water is continuously injected throughout the drying process, resulting in high water consumption. A single drying cycle consumes over 80 liters of water, far exceeding the water consumption for washing. Furthermore, the tap water used for condensation in washer-dryer combos flows away directly, leading to significant heat loss. The heater must continuously operate at high power, and the drain pump needs to be started periodically to drain water, resulting in high overall electricity consumption.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] This invention addresses the aforementioned problems in the prior art by proposing a garment processing device that improves drying efficiency and reduces energy consumption.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: A garment processing device, comprising: outer cylinder; The drying air duct is connected at both ends to the air inlet and air outlet on the outer cylinder, respectively. The drying air duct has a condensing air duct connected to the air outlet, an auxiliary air duct sleeved outside the condensing air duct, and a heating air duct. One end of the heating air duct is connected to the air inlet, and the other end is connected to the auxiliary air duct. A condenser for condensing gas is provided inside the condensing air duct, and a heat dissipation component for absorbing heat from the condenser is provided outside the condensing air duct. The heat dissipation component is located inside the auxiliary air duct, and the end of the auxiliary air duct away from the heating air duct is a fresh air inlet. The fresh air entering from the fresh air inlet absorbs heat after passing through the heat dissipation component, and then flows into the heating air duct together with the gas flowing out of the condenser air duct.

[0007] In some embodiments of this application, the condensing air duct has a heat-conducting pipe located outside the condensing element, and the heat-conducting pipe is made of a material with high thermal conductivity; the auxiliary air duct is made of a material with low thermal conductivity.

[0008] In some embodiments of this application, a plurality of connectors for transferring heat are provided between the condenser and the heat dissipation component. The connectors pass through the heat pipe and are respectively connected to the condenser and the heat dissipation component.

[0009] In some embodiments of this application, the condenser is an arc-shaped structure with a central protrusion along the airflow direction, and the hot and humid gas in the condensation duct flows through the condenser for condensation; the condenser is provided with a plurality of condensation holes for gas outflow, and the clothing treatment device also has a water supply pipe for spraying water onto the condenser.

[0010] In some embodiments of this application, the water supply pipe has a nozzle located on the upper side of the middle of the condenser, and the airflow in the condenser duct passes through the condenser from bottom to top; the water sprayed from the nozzle onto the condenser can flow along the upper surface of the condenser towards the edge.

[0011] In some embodiments of this application, when the water supply pipe is turned on, a water film can be formed at the condensation hole of the condenser; the gas in the condensation duct can break through the water film and flow upward, and then a water film can be formed again at the condensation hole; the formation and rupture of the water film at the condensation hole alternate.

[0012] In some embodiments of this application, the condensation hole has a first groove and a second groove that are relatively recessed, and a communication port connecting the first groove and the second groove; water flows into the first groove to form the water film.

[0013] In some embodiments of this application, the first groove protrudes along the upper end of the condenser towards the communication port, and the protrusion height of the first groove is greater than the protrusion height of the second groove.

[0014] In some embodiments of this application, the inner wall of the first slot is an arc-shaped structure, and the communication port is located at the lower part of the first slot.

[0015] In some embodiments of this application, the condensation hole can serve to filter lint; the broken water film forms a fine water flow that flows downward along the condensation hole, which can carry away the lint at the condensation hole.

[0016] In some embodiments of this application, the heating duct is provided with a heater and a fan, the air inlet of the fan is the other end of the heating duct, one end of the condensing duct is connected to the air outlet, and the other end extends into the auxiliary duct and is located close to the air inlet.

[0017] In some embodiments of this application, the outer cylinder is provided with a vent hole that communicates with the outside, and some of the gas inside the outer cylinder is discharged through the vent hole.

[0018] Compared with existing technologies, the advantages and positive effects of this invention are as follows: First, by setting up a condenser for condensation, it is no longer necessary to rely solely on large amounts of tap water for condensation, effectively reducing water consumption during the drying process and reducing the moisture carried in the airflow after condensation. Second, a heat dissipation component is set up to absorb heat from the condenser, and a fresh air inlet is provided. After absorbing heat through the heat dissipation component, the fresh air flows into the heating duct along with the gas flowing out of the condenser duct. This waste heat utilization method means that the heater does not need to operate at high power continuously, reducing energy consumption and thus lowering power consumption. Third, the specially designed condenser ensures the condensation effect on the humid and hot gas in the condenser duct, which is beneficial for removing moisture from clothes more quickly and accelerating the drying speed. Fourth, after absorbing heat from the heat dissipation component, the fresh air enters the heating duct along with the gas flowing out of the condenser duct, so that the gas temperature in the drying duct can be maintained more effectively within a suitable drying temperature range, realizing the recycling of heat and further improving drying efficiency.

[0028] See Figures 1-4 This is an embodiment of the clothing processing equipment proposed in this invention. The clothing processing equipment includes: a housing 100, an outer cylinder 210 and an inner cylinder 220 that are fitted together, and a drying air duct 600. An openable and closable door 300 is provided on the front panel of the housing 100. An air inlet 211 and an air outlet 212 are respectively provided on the outer cylinder 210. The air inlet 211 and the air outlet 212 are respectively connected to both ends of the drying air duct 600 to achieve air circulation for drying. The drying air duct 600 has a condensing air duct 610, an auxiliary air duct 620, and a heating air duct 630. One end of the condensing air duct 610 is connected to the air outlet 212, and the other end is located inside the auxiliary air duct 620. The condensing air duct 610 is used to condense the hot and humid air discharged from the air outlet 212. The heating duct 630 is connected at one end to the air inlet 211 and at the other end to the auxiliary duct 620. The heating duct 630 is used to heat the gas and deliver it to the air inlet 211. The auxiliary duct 620 is fitted outside the condensing duct 610, and the end of the auxiliary duct 620 away from the heating duct 630 is the fresh air inlet 621. The drying duct 600 is located between the housing 100 and the outer cylinder 210. Some of the gas in the space between the housing 100 and the outer cylinder 210 can enter the area between the auxiliary duct 620 and the condensing duct 610 through the fresh air inlet 621, and then enter the heating duct 630.

[0029] In this embodiment, a condenser 520 for condensing gas is provided inside the condensing duct 610, and a heat dissipation component 510 for absorbing heat from the condenser 520 is provided outside the condensing duct 610. The heat dissipation component 510 is located inside the auxiliary duct 620. By using the condenser 520 for condensation, the reliance on large amounts of tap water for condensation is eliminated, effectively reducing water consumption during the drying process and reducing the moisture carried in the airflow after condensation. The specially designed condenser 520 ensures the condensation effect of the humid and hot gas inside the condensing duct 610, which facilitates faster removal of moisture from clothes and accelerates the drying speed.

[0030] Fresh air entering through the fresh air inlet 621 absorbs heat through the heat sink 510 and then flows into the heating duct 630 along with the condensed gas exiting the condensing duct 610. During condensation, the condensing element 520 absorbs heat from the humid gas. The heat sink 510 on the outside of the condensing duct 610 can recover the heat absorbed by the condensing element 520. When the fresh air entering through the fresh air inlet 621 flows through the heat sink 510, it absorbs this recovered heat. Then, this portion of the fresh air carrying heat flows into the heating duct 630 along with the gas exiting the condensing duct 610. In this way, the heat that may be lost during condensation is reused, reducing the workload of the heater 900 in the heating duct 630, thereby reducing energy consumption. Furthermore, the heat sink 510 absorbs heat from the condensing element 520, keeping the temperature of the condensing element 520 within a range conducive to condensation. By promptly removing heat through the heat sink 510, it is ensured that the condensing element 520 can continuously and efficiently perform condensation work. When fresh air carrying heat absorbed from the heat sink 510 enters the heating duct 630, it helps maintain the stability of the gas temperature inside the heating duct 630; a suitable and stable temperature can also accelerate the evaporation rate of moisture in the clothes, thereby increasing the drying speed.

[0031] In some embodiments of this application, see Figure 2 and Figure 3As shown, the condensing duct 610 has a heat-conducting pipe 611 located outside the condensing element 520. The heat-conducting pipe 611 is a section of the duct that forms part of the condensing duct 610 and is located outside the condensing element 520. The heat-conducting pipe 611 is made of a material with high thermal conductivity, which is beneficial for the heat conduction of the heat-conducting pipe 611. It transfers the heat of the humid and hot gas absorbed by the condensing element 520 to the heat-conducting pipe 611, or some of the heat is directly transferred to the heat-conducting pipe 611 when the gas flows through it. It also facilitates the rapid transfer of heat from the heat-conducting pipe 611 to the heat dissipation element 510. The auxiliary duct 620 is made of a material with low thermal conductivity, which can effectively prevent heat from diffusing outward from the wall of the auxiliary duct 620 and reduce heat loss. More heat is retained in the duct. After the fresh air flows through the heat dissipation element 510 and absorbs this retained heat, it enters the heating duct 630 to participate in the drying cycle, which significantly improves the waste heat utilization rate of the entire system.

[0032] In some embodiments of this application, multiple connectors 530 for heat transfer are provided between the condenser 520 and the heat sink 510. The connectors 530 serve to fix the condenser 520 and the heat sink 510, and also facilitate heat transfer. The connectors 530 pass through the heat pipe 611, and their inner and outer ends are respectively connected to the condenser 520 and the heat sink 510. The connectors 530 fix the condenser 520 and the heat sink 510, ensuring that these two key components maintain a relatively stable position during equipment operation. In the gas flow direction through the condenser 520, a heat pipe 611 is provided between the condenser 520 and the heat sink 510 to transfer heat. In the inward and outward direction of the heat pipe 611, a connector 530 passes through the heat pipe 611. The inner end of the connector 530 is located inside the condenser 520, and the outer end is located inside the heat sink 510. The connector 530 can transfer heat from the condenser 520 to the heat sink 510, and the connector 530 can also transfer heat from the heat pipe 611 to the heat sink 510. Multiple heat transfer paths are constructed between the condenser 520 and the heat sink 510.

[0033] In some embodiments of this application, the condenser 520 is an arc-shaped structure with a central bulge along the airflow direction, where the gas flow direction is the direction of gas flow through the condenser 520. The humid and hot gas in the condensation duct 610 flows through the condenser 520 for condensation. The condenser 520's arc-shaped structure with a central bulge along the airflow direction effectively increases the contact area between the humid and hot gas and the condenser 520; allowing more gas molecules to contact the surface of the condenser 520, promoting the condensation of water vapor in the humid and hot gas into liquid water on the surface of the condenser 520, thereby improving condensation efficiency.

[0034] The condenser 520 is provided with multiple condensation holes 521 for gas outflow, allowing hot and humid gas to flow orderly through these holes as it passes through the condenser 520. On the one hand, this prevents gas from accumulating in local areas, ensuring smoother gas flow around the condenser 520, which is beneficial for heat exchange and water vapor condensation. On the other hand, when gas passes through the condensation holes 521, the gas flow rate may change due to the constraint of the hole walls. This change helps to further enhance the contact between water vapor and the condenser 520 and the condensation effect.

[0035] The garment processing equipment also features a water supply pipe 700 for spraying water onto the condenser 520 to improve condensation efficiency. When water is sprayed onto the condenser 520, it absorbs heat from the surface of the condenser 520 and its vicinity, lowering the temperature of the condenser 520 and further promoting the condensation of water vapor in the humid and hot gas. Furthermore, the sprayed water can carry away any liquid water already condensed on the surface of the condenser 520, preventing the formation of a water film that would hinder subsequent condensation and ensuring a consistently stable condensation effect. While turning on the water supply pipe 700 removes some heat, which is not conducive to heat recovery, it improves the condensation efficiency of the condenser 520. The water supply pipe 700 can be turned on or off as needed, and can be configured to be on, intermittently on, or off.

[0036] In some embodiments of this application, the water supply pipe 700 has a nozzle 710 located on the upper side of the middle of the condenser 520, and the airflow in the condenser duct 610 passes through the condenser 520 from bottom to top. The water sprayed from the nozzle 710 onto the condenser 520 can flow along the upper surface of the condenser 520 towards the edge; then it flows downward along the inner wall of the condenser duct 610 into the outer cylinder 210. The water flow will not disperse throughout the condenser duct 610, thus not interfering with the normal upward condensation process of the humid and hot gas passing through the condenser 520, which helps to achieve continuous and stable high-efficiency condensation; and reducing the contact time between the water flow and the gas can effectively prevent the gas from reabsorbing too much moisture after condensation. The nozzle 710 is located on the upper side of the middle of the condenser 520, and the airflow in the condenser duct 610 passes through the condenser 520 from bottom to top. In this way, the sprayed water will flow along the upper surface of the condenser 520 to the edge, and the water flow can fully cover the surface of the condenser 520, increasing the contact area with the condenser 520. This allows the water flow to absorb the heat of the condenser 520 and the humid and hot gas flowing through the condenser hole 521 more efficiently, thereby promoting the rapid condensation of water vapor on the condenser 520.

[0037] In some embodiments of this application, when the water supply pipe 700 is turned on, a water film can be formed at the condensation hole 521 of the condenser 520. Gas within the condensation duct 610 can break through the water film and flow upwards, after which a water film can be formed again at the condensation hole 521; the formation and rupture of the water film at the condensation hole 521 occur alternately. When the water film is formed, it can exchange heat with the humid gas passing through the condensation hole 521; water has a high specific heat capacity, allowing it to absorb heat from the humid gas, making it easier for water vapor to condense on the surface of the water film, achieving efficient heat exchange and enhancing the condensation effect. Compared to gas directly contacting the condenser 520, during the process of the gas breaking through the water film, it can come into contact with more water molecules, making it easier for water vapor in the humid gas to find attachment points and condense into liquid water, providing more opportunities for water vapor condensation. The formation and rupture of the water film regulates the gas flow rate. When the gas breaks through the water film, it encounters resistance, preventing excessive gas flow that could cause some water vapor to pass through the condensation hole 521 before condensation. Simultaneously, this resistance is not excessive, ensuring a continuous and stable upward flow of gas and allowing the condensation process to proceed smoothly. The alternating formation and rupture of the water film ensures its continuous renewal, maintaining a consistently low temperature, which is beneficial for efficient heat absorption and promotes condensation. During the process of the gas breaking through the water film, it may carry away tiny lint and impurities adhering to the area around the condensation hole 521. This alternating process effectively prevents the accumulation of impurities, ensuring the unobstructed flow of the condensation hole 521. The condensation hole 521 acts as a filter for lint, eliminating the need for a dedicated lint filter within the drying duct 600, reducing components, and allowing for self-cleaning of lint at the condensation hole 521.

[0038] In some embodiments of this application, see Figure 4As shown, the condensation hole 521 has a first groove 5211 and a second groove 5212 that are relatively recessed, and a connecting opening 5213 connecting the first groove 5211 and the second groove 5212; water flows into the first groove 5211 and forms a water film. The recessed design of the first groove 5211 provides a dedicated space for water flow; when water flows into the first groove 5211, due to the structural constraints of the groove, the water can accumulate in the first groove 5211 and form a water film. The first groove 5211 is like a miniature reservoir, allowing the water film to form in a relatively stable environment, thus enhancing the stability of the water film. Furthermore, the recessed design of the first groove 5211 can isolate external factors from interfering with the water film to a certain extent, ensuring that the water film can continuously and effectively play its role in the condensation process. After the water film forms in the first groove 5211, its high stability increases the contact area and contact time between the hot and humid gas and the water film, providing more opportunities for heat exchange. Water vapor condenses more easily on the water film, thus improving condensation efficiency. The upward-flowing gas first accumulates in the second groove 5212, then flows upward through the connecting port 5213 and breaks through the water film in the first groove 5211. The relative concavity, where the first groove 5211 and the second groove 5212 are recessed towards each other, prevents wire debris from accumulating in the condensation hole 521. The broken water film forms a fine water flow along the connecting port 5213 at the bottom of the first groove 5211, flowing downwards along the inner wall of the second groove 5212. This carries away wire debris located at the connecting port 5213 or in the second groove 5212, reducing the possibility of blockage and ensuring the unobstructed flow of the condensation hole 521, which is beneficial for long-term stable condensation operation.

[0039] In some embodiments of this application, the first groove 5211 protrudes from the upper end of the condenser 520 towards the connecting port 5213, making it easier for water sprayed from the nozzle to accumulate in the first groove 5211. The direction of the protrusion follows the natural flow direction of water under gravity, which helps the water flow to enter the first groove 5211 more smoothly and form a water film. The second groove 5212 protrudes from the lower end of the condenser 520 towards the connecting port 5213, and the protrusion height of the first groove 5211 is greater than the protrusion height of the second groove 5212.

[0040] In some embodiments of this application, the inner wall of the first groove 5211 is an arc-shaped structure, which allows the water flow entering the groove to be more evenly distributed within the groove, enabling the hot and humid gas to make more thorough contact with the water film when passing through the first groove 5211. The connecting port 5213 is located at the lower part of the first groove 5212. When the water film breaks, the resulting fine water flow can naturally flow downwards through the connecting port 5213 under the action of gravity, and the action of gravity can be used to prevent impurities from clogging the connecting port 5213.

[0041] In some embodiments of this application, the heat-absorbing element 520 is preferably configured as a multi-layer ultra-dense metal mesh with a spherical structure; the heat-dissipating element 510 is preferably made of a porous, breathable, and easily heat-conducting material, such as aluminum foam or copper.

[0042] In some embodiments of this application, a heater 900 and a fan 800 are provided inside the heating duct 630. The air inlet 810 of the fan 800 is the other end of the heating duct 630, that is, the air inlet of the fan 800 is connected to the auxiliary duct 620. One end of the condensing duct 610 is connected to the air outlet 212, and the other end is located inside the auxiliary duct 620 and close to the air inlet 810. The gas flowing out of the condensing duct 610 and the fresh air in the auxiliary duct 620 enter the heating duct 630 through the fan 800. After being heated by the heater 900 in the heating duct 630, the gas then passes through the drying duct to dry the clothes. The fan 800, as the power source for air circulation, can effectively draw the condensed gas and the fresh air with residual heat into the heating duct 630, ensuring strong air circulation. This ensures that there is enough dry air continuously flowing through the clothes during the drying process, accelerating the evaporation rate of moisture in the clothes, thereby improving drying efficiency. The positional relationship between the condenser duct 610, auxiliary duct 620, heating duct 630, and fan 800 makes full use of the internal space of the equipment and avoids space waste caused by excessively long ducts or overly complex layouts.

[0043] In some embodiments of this application, the outer cylinder 210 is provided with a vent hole communicating with the outside, through which some of the gas inside the outer cylinder 210 is discharged. Since fresh air enters the drying duct 600 through the auxiliary air duct 620, the vent hole on the outer cylinder 210 allows some gas to be discharged, maintaining the internal air pressure at a relatively stable state. This ensures that the gas in the duct can flow normally according to the designed direction and speed, avoiding obstruction of gas circulation due to excessively high air pressure. Discharging some gas through the vent hole also removes high-humidity gas from the equipment, keeping the humidity in the drying duct 600 and the outer cylinder 210 within a relatively suitable range, thus accelerating the evaporation of moisture from the clothing.

[0044] In some embodiments of this application, during the drying process of the clothing processing equipment, the water supply pipe 700 can be turned on or off according to the actual situation. A quick-drying mode with the water supply pipe 700 turned on can be set, an energy-saving mode with the water supply pipe 700 turned on at regular intervals can be set, and a water-saving mode with the water supply pipe 700 turned off can be set.

[0045] A method for controlling the drying of clothing processing equipment, comprising: After the drying program is started, it is determined whether the water film mode has been activated; the temperature inside the condenser duct 610 is detected, and when the first set condition is reached, the water supply pipe 700 is opened, so that water is sprayed onto the upper surface of the condenser 520 to form a water film.

[0046] In some embodiments of this application, the gas temperature at the air outlet 212 is T1, and the gas temperature at the end of the condensing air duct 610 near the heating air duct 630 is T2; the first setting condition is that T1 is greater than or equal to the first setting temperature, and the temperature difference between T1 and T2 is greater than or equal to the first setting value.

[0047] In some embodiments of this application, the method further includes the step of detecting whether the condensation hole 521 is blocked; detecting the air pressure in the drying air duct 600 to determine whether the flushing mode has been activated; and when the second set condition is met, opening the water supply pipe 700 so that water is sprayed onto the upper surface of the condenser 520 and flows downward through the condensation hole 521 to flush the lint at the condensation hole 521.

[0048] In some embodiments of this application, the second setting condition is that the air pressure in the drying air duct 600 is greater than or equal to the second set air pressure.

[0049] In some embodiments of this application, the water supply pipe 700 can be configured with multiple settings, such as a water film setting, a rinsing setting, etc., to adjust the water pressure of the spray water flow.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
