Description

Technical Field

[0001] This invention belongs to the field of condensation technology, specifically relating to a condensation container and clothing processing equipment. Background Technology

[0002] Condensation refers to the condensation phenomenon that occurs when a gas or liquid is cooled. In production and daily life, condensation is commonly used to remove moisture from gases. A condenser is a device used to fill with water or other heat-absorbing condensing media, causing the warm, humid air flowing over its surface to condense and thus remove moisture from the gas.

[0003] In the prior art, the condensing container is provided with an inlet and an outlet that communicate with the medium chamber inside. An inlet valve and an outlet valve are respectively installed at the inlet and outlet. After the condensing medium in the medium chamber absorbs heat, its temperature will rise. After the temperature of the condensing medium rises to a certain level, it can no longer condense the hot and humid air on the surface of the condensing container. At this time, it is necessary to open the outlet valve to discharge the high-temperature condensing medium in the medium chamber, and open the inlet valve to add low-temperature condensing medium back into the medium chamber so that condensation can continue.

[0004] In existing condenser containers, the timing of the opening and closing of the inlet and outlet valves is not easy to control. The medium chamber is often emptied before the low-temperature condensing medium is added again, resulting in large temperature fluctuations in the condenser container and the condensing medium inside, which affects the performance. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, namely, to solve the problem of large temperature fluctuations in the condensing container and the condensing medium inside, which affects the performance, the present invention provides a condensing container, which has a medium cavity for storing the condensing medium, and the upper and lower parts of the condensing container are respectively provided with a medium inlet and a medium outlet communicating with the medium cavity.

[0006] A liquid level control valve is installed in the medium chamber to control the opening and closing of the medium inlet; the liquid level control valve closes when the liquid level in the medium chamber reaches the preset liquid level and opens when the liquid level in the medium chamber is lower than the preset liquid level.

[0007] A pressure control valve is installed at the medium outlet to control the opening and closing of the medium outlet; the pressure control valve opens when the pressure is not less than the preset pressure and closes when the pressure is less than the preset pressure.

[0008] The preset pressure is equal to the pressure on the pressure control valve when both the level control valve and the pressure control valve are closed and the temperature inside the medium chamber is equal to the preset temperature; the pressure on the pressure control valve is less than the preset pressure when the level control valve switches from the open state to the closed state.

[0009] In the preferred technical solution of the above-mentioned condensation container, the liquid level control valve includes a float, a guide sleeve and a first sealing element. The guide sleeve is fastened to the inner wall of the medium cavity, the float is slidably connected to the guide sleeve, and the float can slide up and down along the guide sleeve. The top of the float is fastened to the first sealing element, which is located directly below the medium inlet. The float is used to drive the first sealing element to move between blocking the medium inlet and moving away from the medium inlet.

[0010] In the preferred embodiment of the above-mentioned condensation container, a rigid straight rod is fastened to the center of the top surface of the float, and a guide sleeve is fitted over the rigid straight rod and the two are slidably connected. The rigid straight rod can slide up and down along the guide sleeve, and the float is slidably connected to the guide sleeve through the rigid straight rod.

[0011] The first sealing element is fastened to the rigid straight rod, and the first sealing element is located above the guide sleeve.

[0012] In the preferred embodiment of the above-mentioned condensing container, the liquid level control valve further includes a second sealing element, which is located at the top of the rigid straight rod. The float is also used to drive the second sealing element to move between sealing the liquid injection port and moving away from the liquid injection port. The liquid injection port is located outside the condensing container and directly above the medium inlet.

[0013] The first sealing element is an elastic sleeve, which is fitted onto the outer wall of the rigid straight rod, and the lower end of the elastic sleeve is tightly connected to the outer wall of the rigid straight rod. The elastic sleeve is located below the second sealing element, and the upper end of the elastic sleeve is used to seal the medium inlet.

[0014] In the preferred technical solution of the above-mentioned condensation container, the second sealing element is an elastic cone plug with the small end facing upward.

[0015] In the preferred embodiment of the above-mentioned condensation container, the top wall of the medium cavity includes a horizontal surface area, and the medium inlet is located in the horizontal surface area.

[0016] In the preferred embodiment of the condenser described above, a striker is fastened to the bottom of the float, and the striker is located directly above the medium outlet.

[0017] The striker increases the pressure on the pressure control valve in response to the descent of the float, thereby driving the pressure control valve to open the medium outlet; the striker also decreases the pressure on the pressure control valve in response to the rise of the float, thereby driving the pressure control valve to close the medium outlet. The opening degree of the pressure control valve when it opens is less than that of the liquid level control valve when it opens. When the liquid level in the medium chamber is lower than the preset liquid level, the pressure on the pressure control valve is greater than the preset pressure.

[0018] In the preferred embodiment of the above-mentioned condenser, the pressure control valve includes a plurality of openable and closable elastic valves arranged circumferentially along the medium outlet.

[0019] When the pressure applied is not less than the preset pressure, multiple elastic valves open; when the pressure applied is less than the preset pressure, multiple elastic valves close.

[0020] The striking pin includes a rod and a ball head. The upper end of the rod is fastened to the bottom end of the float, and the lower end of the rod is fastened to the ball head. The ball head is used to squeeze one or more elastic valves when the float descends, so that the multiple elastic valves open.

[0021] The present invention also provides a garment processing device, including the above-described condenser container.

[0022] The garment processing equipment is equipped with a water supply pipe and a drying system. The side wall of the garment processing equipment is provided with a garment loading and unloading port that connects to the garment drying chamber. A sealing door is provided at the garment loading and unloading port. The condenser container is located on the sealing door and is located on the side of the sealing door facing the garment drying chamber. The drying system is used to dry the clothes in the garment drying chamber.

[0023] The medium inlet is connected to the water supply pipe, and the medium outlet is connected to the drain pipe of the clothing processing equipment.

[0024] In the preferred technical solution of the above-mentioned clothing processing equipment, the sealing door includes a door ring, an outer cover, and an inner shell. The door ring is installed at the clothing loading and unloading port, and the outer cover is located on the surface of the door ring facing the outside of the clothing processing equipment. The outer cover is a heat-proof cover. The inner shell is basin-shaped and extends into the clothing loading and unloading port. The inner shell is made of stainless steel. The basin opening of the inner shell is fixedly connected to the surface of the door ring facing the clothing drying chamber. The door ring, the outer cover, and the inner shell define a medium chamber. The medium inlet and the medium outlet are both located on the peripheral wall of the inner shell.

[0025] And / or, the water outlet of the water supply pipe is located on the inner wall of the clothing loading and unloading port, and is spaced apart directly above the medium inlet. The water outlet of the water supply pipe serves as the injection port for injecting water into the medium inlet. The opening of the medium inlet is greater than the opening of the injection port. When the liquid level in the medium chamber reaches the preset liquid level, the elastic sleeve of the liquid level control valve blocks the medium inlet, and the elastic cone plug of the liquid level control valve blocks the water outlet of the water supply pipe.

[0026] Those skilled in the art will understand that the condensation container of the present invention includes a liquid level control valve disposed within its medium cavity for controlling the opening and closing of the medium inlet and a pressure control valve disposed at the medium outlet for controlling the opening and closing of the medium outlet. The liquid level control valve closes when the liquid level in the medium cavity reaches a preset liquid level and opens when the liquid level in the medium cavity is lower than the preset liquid level. The pressure control valve opens when the pressure it receives is not less than a preset pressure and closes when the pressure it receives is less than the preset pressure. The preset pressure is equal to the pressure received by the pressure control valve when both the liquid level control valve and the pressure control valve are closed and the temperature in the medium cavity is equal to a preset temperature.

[0027] With the above settings, during condensation, condensing medium is added to the medium chamber through the medium inlet. When the liquid level of the added condensing medium in the medium chamber reaches the preset level, the liquid level control valve closes. The pressure control valve also closes when the pressure it experiences is less than the preset pressure. The condensing medium stored in the medium chamber absorbs heat, condensing the gas or liquid on the surface of the condensing container. As the condensing medium absorbs heat, the temperature and pressure within the sealed medium chamber rise simultaneously. When the temperature in the medium chamber reaches the preset temperature, the pressure within the medium chamber equals the preset pressure, causing the pressure control valve to open. The condensing medium in the medium chamber is then discharged through the medium outlet. Simultaneously, the liquid level in the medium chamber drops from the preset level, causing the level control valve to open. Lower-temperature condensate from the outside is injected into the medium chamber through the medium inlet. As the level control valve opens, the medium chamber depressurizes. The lower-temperature condensate flows into the medium chamber, mixing with the existing condensate to lower the temperature and simultaneously raising the liquid level. Once the preset level is reached, the level control valve closes again. At this point, the pressure control valve experiences less pressure than the preset pressure and is also closed, making the medium chamber a sealed chamber again. This process continues until the temperature inside the medium chamber rises to the preset temperature, causing the pressure control valve to reopen and repeating the above steps. When replacing the condensate in the medium chamber, the pressure control valve and the level control valve open synchronously for a short period. After a small amount of high-temperature condensate is discharged and a corresponding small amount of low-temperature condensate is added, the pressure control valve and the level control valve close again. The amount of condensing medium in the medium chamber is small each time it is replaced, and the temperature fluctuation in the medium chamber is small. Throughout the condensation process, the condensing medium in the medium chamber is always in a state of small-scale dynamic replacement. The temperature in the medium chamber fluctuates within a small range around the preset temperature, resulting in a more balanced condensation effect and no interruption of condensation. In addition, in some equipment that requires the recovery of heat from the gas or liquid outside the condensation container, it can reduce the heat loss of the gas or liquid outside the condensation container caused by condensation.

Detailed Implementation

[0037] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0038] Secondly, it should be noted that in the description of this invention, terms such as "inner" and "outer" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0039] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] In existing condenser containers, when replacing the high-temperature condensing medium in the medium chamber, a complete replacement method is often used. This involves completely draining the high-temperature condensing medium from the medium chamber and then refilling it with a low-temperature condensing medium. This results in large temperature fluctuations within the medium chamber, affecting performance. Furthermore, if the replenishment of condensing medium is not timely after the complete replacement, condensation may be interrupted. Additionally, for equipment requiring heat recovery from gases or liquids outside the condenser container, a complete replacement of the condensing medium leads to a low condenser container temperature and significant heat loss from the surrounding gases or liquids.

[0041] To solve the above problems, the inventors of this case installed a level control valve in the medium cavity of the condensing container to control the opening and closing of the medium inlet, and a pressure control valve at the medium outlet of the condensing container to control the opening and closing of the medium outlet. The level control valve closes when the liquid level in the medium cavity reaches a preset level and opens when the liquid level in the medium cavity is lower than the preset level. The pressure control valve opens when the pressure it receives is not less than a preset pressure and closes when the pressure it receives is less than the preset pressure.

[0042] During condensation, condensing medium is added into the medium chamber through the medium inlet. When the liquid level of the added condensing medium in the medium chamber reaches the preset liquid level, the liquid level control valve closes. When the pressure on the pressure control valve is less than the preset pressure, the pressure control valve also closes, and the medium chamber is in a sealed state. After the medium absorbs heat, the temperature and pressure inside the sealed medium chamber rise simultaneously. When the temperature inside the medium chamber reaches the preset temperature, the pressure inside the medium chamber equals the preset pressure, causing the pressure control valve to open. The condensed medium inside the medium chamber is discharged through the medium outlet. At the same time as the condensed medium is discharged through the medium outlet, the liquid level inside the medium chamber drops from the preset liquid level, causing the liquid level control valve to open. The condensed medium with a lower external temperature is injected into the medium chamber through the medium inlet. At the same time as the liquid level control valve opens, the medium chamber is depressurized. After the condensed medium with a lower external temperature flows into the medium chamber, it mixes with the original condensed medium inside the medium chamber, lowering the temperature inside the medium chamber, and at the same time, it causes the liquid level inside the medium chamber to rise. When the liquid level reaches the preset liquid level, the liquid level control valve closes again. At this time, the pressure on the pressure control valve is less than the preset pressure, so it is also in the closed state. The medium chamber becomes a sealed chamber again until the temperature inside the medium chamber rises to the preset temperature, causing the pressure control valve to open again, and the above steps are repeated.

[0043] When replacing the condensing medium in the medium chamber, the pressure control valve and the level control valve open synchronously for a short period of time. After a small amount of high-temperature condensing medium is discharged from the medium chamber and a corresponding small amount of low-temperature condensing medium is added, the pressure control valve and the level control valve close again. Each replacement of the condensing medium in the medium chamber involves a small amount of condensing medium, resulting in minimal temperature fluctuations within the medium chamber. Throughout the condensation process, the condensing medium in the medium chamber is constantly and dynamically replaced in small amounts. The temperature within the medium chamber fluctuates within a small range around the preset temperature, resulting in a more balanced condensation effect, preventing condensation interruptions, and reducing heat loss from the gas or liquid outside the condensation container caused by condensation.

[0044] The preferred technical solutions of the condenser container and clothing processing equipment of the present invention are described below with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic diagram showing the liquid level in the medium chamber of an embodiment of the proposed condensation container when it is lower than a preset liquid level. Figure 2 This is a schematic diagram showing the liquid level in the medium chamber of the proposed condenser container when it reaches a preset level.

[0046] like Figure 1 , Figure 2 As shown in the embodiment of the condensing container of the present invention, the condensing container 100 has a medium cavity 110 for storing condensing medium, and the upper and lower parts of the condensing container 100 are respectively provided with a medium inlet 120 and a medium outlet 130 communicating with the medium cavity 110.

[0047] A liquid level control valve 200 is provided in the medium chamber 110 to control the opening and closing of the medium inlet 120; the liquid level control valve 200 closes when the liquid level in the medium chamber 110 reaches the preset liquid level and opens when the liquid level in the medium chamber 110 is lower than the preset liquid level.

[0048] A pressure control valve 300 is provided at the medium outlet 130 to control the opening and closing of the medium outlet 130; the pressure control valve 300 opens when the pressure it receives is not less than the preset pressure and closes when the pressure it receives is less than the preset pressure.

[0049] Specifically, the pressure is equal to the pressure on the pressure control valve 300 when both the level control valve 200 and the pressure control valve 300 are closed and the temperature in the medium chamber 110 is equal to the preset temperature; the pressure on the pressure control valve 300 is less than the preset pressure when the level control valve 200 switches from the open state to the closed state.

[0050] It is understandable that the preset temperature is higher than the temperature of the condensing medium added into the medium cavity 110.

[0051] In the above embodiment, before the condensing medium is injected into the medium chamber 110, the level control valve 200 is opened, and the condensing medium is injected into the medium chamber 110 through the medium inlet 120. As the condensing medium is injected, the liquid level in the medium chamber 110 gradually rises until the liquid level in the medium chamber 110 reaches the preset liquid level. At this time, the level control valve 200 switches from the open state to the closed state. At this time, the pressure control valve 300 is closed, and the medium chamber 110 forms a sealed chamber. As the condensing medium in the medium chamber 110 absorbs heat, the temperature and pressure in the medium chamber 110 rise simultaneously. When the temperature in the medium chamber 110 reaches the preset temperature, the pressure also reaches the preset pressure. At this time, the pressure control valve 300 opens, and the condensing medium in the medium chamber 110 is discharged from the medium outlet 130, causing the liquid level in the medium chamber 110 to drop. This causes the liquid level control valve 200 to open, releasing the high pressure in the sealed medium chamber 110. At the same time, a lower-temperature condensing medium is injected into the medium chamber 110 from the medium inlet 120. The newly injected condensing medium causes the temperature in the medium chamber 110 to drop and the liquid level to rise. After reaching the preset liquid level, the liquid level control valve 200 closes again, completing one replacement of the condensing medium.

[0052] In this way, the amount of condensing medium in the medium chamber 110 is small each time it is replaced, and the temperature fluctuation in the medium chamber 110 is small. Throughout the condensation process, the condensing medium in the medium chamber 110 is always in a state of small-scale dynamic replacement. The temperature in the medium chamber 110 fluctuates within a small range near the preset temperature, resulting in a more balanced condensation effect. It will not cause condensation interruption and can reduce the heat loss of gas or liquid outside the condensation container 100 caused by condensation.

[0053] In some examples, the medium inlet 120 is located at the top of the medium cavity 110, which increases the storage capacity of the condensing medium in the medium cavity 110, resulting in smaller temperature fluctuations and more stable condensation effect when the condensing medium is replaced.

[0054] In some examples, the medium outlet 130 is located at the bottom of the medium chamber 110. This facilitates the drainage of the condensed medium in the medium chamber 110 after condensation has ended.

[0055] In some possible implementations, the level control valve 200 includes a float 210, a guide sleeve 230, and a first sealing element 240. The guide sleeve 230 is fastened to the inner wall of the medium cavity 110. The float 210 is slidably connected to the guide sleeve 230 and can slide up and down along the guide sleeve 230. The first sealing element 240 is fastened to the top of the float 210 and is located directly below the medium inlet 120. The float 210 is used to drive the first sealing element 240 to move between blocking the medium inlet 120 and moving away from the medium inlet 120.

[0056] It is understandable that the float 210 is made of low-density material, and the density of the float 210 is much smaller than the density of the condensing medium in the injected medium cavity 110. The float 210 can drive the first sealing component 240 to float up and down with the change of liquid level in the medium cavity 110.

[0057] With this configuration, as the liquid level in the medium chamber 110 rises, the float 210 drives the first sealing member 240 to rise. After the liquid level in the medium chamber 110 reaches the preset level, the first sealing member 240 completes the sealing of the medium inlet 120 directly above it. After the liquid level in the medium chamber 110 drops, the float 210 drives the first sealing member 240 to drop, so that the first sealing member 240 moves away from the medium inlet 120, allowing the medium inlet 120 to be connected. The guide sleeve 230 can ensure that the float 210 and the first sealing member 240 move in the vertical direction, ensuring that the first sealing member 240 can accurately seal the medium inlet 120.

[0058] In some examples, the guide sleeve 230 is securely connected to the inner wall of the medium cavity 110 via a connecting bracket. In this way, the float 210, the first sealing element 240, the medium inlet 120, etc., can be arranged closer to the center of the medium cavity 110, which allows for more flexible arrangement and avoids the influence of the inner wall of the medium cavity 110 on the float 210's floating.

[0059] In some possible implementations, a rigid straight rod 220 is fastened to the center of the top surface of the float 210, and a guide sleeve 230 is fitted over the rigid straight rod 220 and the two are slidably connected. The rigid straight rod 220 can slide up and down along the guide sleeve 230. The float 210 is slidably connected to the guide sleeve 230 through the rigid straight rod 220. The first sealing member 240 is fastened to the rigid straight rod 220 and is located above the guide sleeve 230.

[0060] This configuration allows the liquid level in the medium chamber 110 to maintain a certain distance from the first sealing element 240. After the first sealing element 240 blocks the medium inlet 120, a certain space is left in the medium chamber 110. The gas in the space generates high pressure after heating, which is conducive to opening the pressure control valve 300.

[0061] In some possible implementations, the level control valve 200 further includes a second sealing element 250, which is located at the top of the rigid straight rod 220. The float 210 is also used to drive the second sealing element 250 to move between blocking the injection port 150 and away from the injection port 150, wherein the injection port 150 is located outside the condenser 100 and directly above the medium inlet 120.

[0062] It is understandable that the float 210 drives the first sealing element 240 and the second sealing element 250 to move synchronously. While the first sealing element 240 blocks the medium inlet 120, the second sealing element 250 blocks the liquid injection port 150.

[0063] This configuration allows for the synchronous connection or disconnection of the medium inlet 120 and the injection port 150 when a liquid inlet 150 for adding condensing medium into the medium cavity 110 is provided outside the condensing container 100. This avoids the condensing medium from flowing out of the injection port 150 after the medium inlet 120 is disconnected.

[0064] In some possible implementations, the first sealing element 240 is an elastic sleeve, which is fitted onto the outer wall of the rigid straight rod 220, and the lower end of the elastic sleeve is fastened to the outer wall of the rigid straight rod 220. The elastic sleeve is located below the second sealing element 250, and the upper end of the elastic sleeve is used to seal the medium inlet 120.

[0065] For example, an elastic sleeve can be a rubber sleeve.

[0066] This configuration allows the first sealing element 240 to block the medium inlet 120 while the second sealing element 250 blocks the injection port 150. This reduces the distance accuracy between the first sealing element 240 and the second sealing element 250, facilitating production and improving the sealing effect on the medium inlet 120 and the injection port 150.

[0067] In some possible implementations, the second sealing element 250 is an elastic cone plug with the small end facing upwards.

[0068] This configuration effectively seals the injection port 150 and also facilitates the connection of the injection port 150 when the float 210 descends.

[0069] In some possible implementations, the top wall of the medium cavity 110 includes a horizontal surface region 140, and the medium inlet 120 is located in the horizontal surface region 140. This arrangement facilitates the engagement of the first sealing member 240 with the horizontal surface region 140, thereby disconnecting the medium inlet 120 and improving the sealing effect on the medium inlet 120.

[0070] In some possible implementations, a striker 400 is fastened to the bottom end of the float 210. The striker 400 is located directly above the medium outlet 130. The striker 400 increases the pressure on the pressure control valve 300 in response to the descent of the float 210, thereby driving the pressure control valve 300 to open the medium outlet 130. The striker 400 also decreases the pressure on the pressure control valve 300 in response to the ascent of the float 210, thereby driving the pressure control valve 300 to close the medium outlet 130. The opening degree of the pressure control valve 300 when it is open is less than the opening degree of the level control valve 200 when it is open. When the liquid level in the medium chamber 110 is lower than the preset liquid level, the pressure on the pressure control valve 300 is greater than the preset pressure.

[0071] With this configuration, when it is necessary to discharge the condensed medium in the medium chamber 110, the striker 400 can open the pressure control valve 300, which facilitates the discharge of the condensed medium through the medium outlet 130. The opening degree of the pressure control valve 300 is less than the opening degree of the level control valve 200, ensuring that when the pressure control valve 300 and the level control valve 200 are opened at the same time, the condensed medium injected through the medium inlet 120 can raise the liquid level in the medium chamber 110.

[0072] For example, when condensation is about to end, the addition of condensing medium to the medium inlet 120 can be stopped. After the pressure in the sealed medium chamber 110 exceeds the preset pressure, the pressure control valve 300 opens, and the condensing medium in the medium chamber 110 begins to drain out. The liquid level in the medium chamber 110 decreases, and the striker 400 keeps the pressure control valve 300 open. Since no new condensing medium is injected, the float 210 will not float up again. The striker 400 is always in the state of keeping the pressure control valve 300 open, so that the condensing medium in the medium chamber 110 can be drained after condensation is completed.

[0073] Of course, in some other examples, the bottom of the float 210 may not have a striker 400. When drainage is required, pressure is applied to the pressure control valve 300 by other structures or external pressure, causing the pressure control valve 300 to open. For example, after condensation is complete, force is applied to the pressure control valve 300 from the medium outlet 130, causing the pressure control valve 300 to open.

[0075] like Figure 3 , Figure 4 As shown, in some possible embodiments, the pressure control valve 300 includes a plurality of openable and closable elastic valves 310 arranged circumferentially along the medium outlet 130. When the pressure is not less than a preset pressure, the plurality of elastic valves 310 open; when the pressure is less than the preset pressure, the plurality of elastic valves 310 close.

[0076] With this configuration, when the pressure on the elastic valve 310 is less than the preset pressure, the sealing performance can be guaranteed. When the pressure on the elastic valve 310 is greater than the preset pressure, the elastic valve 310 is squeezed and deformed, and gaps are generated between each elastic valve 310, which can connect the medium outlet 130. This facilitates switching the medium outlet 130 according to the pressure in the medium cavity 110, and the structure is simple.

[0077] For example, the elastic valve 310 can be a rubber valve, and the pressure control valve 300 can be a rubber diaphragm with a cross-shaped cut in the middle, forming four elastic valves 310 on the four sides of the cross-shaped cut.

[0078] In an embodiment with a striker 400, the striker 400 includes a rod 410 and a ball head 420. The upper end of the rod 410 is fastened to the bottom end of the float 210, and the lower end of the rod 410 is fastened to the ball head 420. The ball head 420 is used to squeeze one or more elastic valves 310 when the float 210 descends, so that the multiple elastic valves 310 open.

[0079] This configuration increases the opening of the gap between multiple elastic valves 310, which helps to improve the efficiency of discharging the condensed medium in the media chamber 110.

[0080] Figure 5 This is a schematic diagram showing the liquid level in the medium chamber of an embodiment of the proposed clothing processing device when it is lower than a preset liquid level. Figure 6 This is a schematic diagram showing the liquid level in the medium chamber reaching a preset level in an embodiment of the proposed clothing processing device. Figure 5 , Figure 6 and combined Figures 1-4 As shown, an embodiment of the garment processing device of the present invention specifically includes a condenser container 100, wherein the condenser container 100 is the condenser container 100 in any of the above embodiments.

[0081] The garment processing equipment is equipped with a water supply pipe 510 and a drying system 520. The side wall of the garment processing equipment is provided with a garment loading and unloading port 530 that connects to the garment drying chamber 540. A sealing door 550 is provided at the garment loading and unloading port 530. A condenser 100 is provided on the sealing door 550 and is located on the side of the sealing door 550 facing the garment drying chamber 540. The drying system 520 is used to dry the clothes in the garment drying chamber 540.

[0082] The medium inlet 120 is connected to the water supply pipe 510, and the medium outlet 130 is connected to the drain pipe 560 of the clothing processing equipment.

[0083] It is understandable that the aforementioned clothing processing equipment can be a dryer, or a washer-dryer combo, or any other clothing processing equipment with drying functions.

[0084] In the above embodiment, the amount of condensing medium in the medium chamber 110 is small each time it is replaced, and the temperature fluctuation in the medium chamber 110 is small. Throughout the condensation process, the condensing medium in the medium chamber 110 is always in a state of small-scale dynamic replacement. The temperature in the medium chamber 110 fluctuates within a small range near the preset temperature, resulting in a more balanced condensation effect. It will not cause condensation interruption and can reduce the heat loss of the gas in the clothes drying chamber 540 caused by condensation, thereby reducing the burden on the drying system 520.

[0085] It is understood that both the air supply end and the air inlet end of the drying system 520 are connected to the clothes drying chamber 540. The drying system 520 includes an air duct 522 and a fan heating module 523 installed in the air duct 522. The fan heating module 523 includes a fan and a heater. Both the air supply end and the air inlet end of the air duct 522 are connected to the clothes drying chamber 540. The drying system 520 can be a condenser drying system or a hot air drying system. When the drying system 520 is a condenser drying system, it also includes a condenser 521. The air inlet end of the condenser 521 serves as the air inlet end of the drying system 520 and is connected to the clothes drying chamber 540. The air outlet end of the condenser 521 is connected to the air inlet end of the air duct 522. The water outlet end of the condenser 521 is connected to the drain pipe 560 of the clothes processing equipment. In addition, a drain pump 561 can be installed on the drain pipe 560 to achieve top drainage.

[0086] Furthermore, existing dryers, washer-dryer combos, and other garment processing equipment with drying functions use a drying system 520 to supply hot air into the garment drying chamber 540. This hot air dries the clothes inside the drying chamber 540. The high humidity inside the drying chamber 540 leads to low drying efficiency, long drying times, and high energy consumption. Additionally, the sealed door 550 of existing garment processing equipment is in direct contact with the hot air inside the drying chamber 540. The high temperature inside the sealed door during the drying process can easily burn users and cause a significant increase in ambient temperature. If the drying system 520 uses a condenser drying system, the condenser drying system directly contacts the humid air with a continuously supplied supply of condensing water, condensing the moisture in the air, and then heating the condensed air before sending it back into the drying chamber 540 to exchange heat with the clothes and evaporate the moisture. During the drying process, to ensure the condensation effect on the intake air, the condenser drying system requires a continuous and large supply of condensing water. After contacting the humid air, the condensing water flows directly into the drain pipe 560 of the garment processing equipment for discharge. This results in high water consumption and significant water waste during the drying process. Furthermore, because the air comes into direct contact with the condensing water during condensation, the humidity of the air delivered into the garment drying chamber 540 by the condenser drying system remains high. In addition, the air intake of the condenser drying system is condensed by a large amount of condensing water before being heated, resulting in significant heat loss. The heater of the condenser drying system must operate continuously at a power of 1.8kW or higher for extended periods, leading to high energy consumption.

[0087] In the above embodiment, a condenser container 100 is provided on the sealing door 550, and a water supply pipe 510 is configured inside the clothing processing equipment. During drying, the sealing door 550 is closed, and cold water is supplied to the medium chamber 110 through the water supply pipe 510 via the medium inlet 120. The condenser container 100, which stores cold water, can condense the air flowing through its surface in the clothing drying chamber 540 to remove moisture from the air. When the water in the medium chamber 110 absorbs heat and the temperature inside the medium chamber 110 reaches the preset temperature, the water in the medium chamber 110 is automatically replaced, and the temperature of the condenser container 100 is always maintained near the preset temperature.

[0088] Thus, the condenser container 100 installed on the sealing door 550 can condense the air inside the clothes drying chamber 540, reducing the humidity of the air entering the clothes drying chamber 540, improving drying efficiency, shortening drying time, and reducing energy consumption. When the drying system 520 adopts a condenser drying system, the condensing water supplied to the condenser drying system condenses the intake air and is then directly discharged, while the cold water supplied to the media chamber 110 is retained in the media chamber 110 to absorb heat. It is replaced after reaching a certain temperature. The utilization rate of the water supplied to the media chamber 110 is higher, which can reduce the amount of condensing water supplied to the condenser drying system and save water. In addition, by absorbing the heat at the sealing door 550 by the cold water in the condenser container 100, the temperature of the sealing door 550 can be prevented from becoming too high, causing burns to the user or significantly increasing the ambient temperature.

[0089] In the embodiment where the drying system 520 employs a condenser drying system, the reduced amount of condensing water supplied to the system results in less heat being carried away from the air by the flowing condensing water. Consequently, more heat is recovered from the air entering the system, reducing the load on the heater and / or increasing the temperature of the air entering the drying chamber 540. This leads to energy savings and / or improved drying efficiency. Furthermore, the air undergoes two stages of condensation—through the condenser drying system and the condenser container 100 on the sealing door 550—extending the condensation path and improving the condensation effect.

[0090] In some possible implementations, the sealing door 550 includes a door ring 551, an outer cover, and an inner shell 552. The door ring 551 is closable and installed at the clothing loading / unloading port 530. The outer cover is located on the surface of the door ring 551 facing the outside of the clothing handling equipment. The inner shell 552 is basin-shaped and extends into the clothing loading / unloading port 530. The basin opening of the inner shell 552 is fixedly connected to the surface of the door ring 551 facing the clothing drying chamber 540. The door ring 551, the outer cover, and the inner shell 552 define a medium chamber 110. The medium inlet 120 and the medium outlet 130 are both located on the peripheral wall of the inner shell 552.

[0091] With this configuration, the condenser container 100 is formed directly on the sealing door 550, without the need for other structures, making it easy to manufacture and inexpensive.

[0092] For example, the inner shell 552 is a vertical basin-shaped structure with a large opening and a small bottom, with the bottom of the basin facing the clothes drying chamber 540.

[0093] In some examples, the outer cover is a heat shield. This minimizes the temperature outside the sealed door 550.

[0094] In some examples, the inner shell 552 is made of stainless steel. This improves the condensation effect on the surface of the inner shell 552.

[0095] In some examples, one side of the door ring 551 can be hinged to the position corresponding to the clothing access opening 530. This facilitates the opening and closing of the sealing door 550.

[0096] In some examples, such as drum dryers or washer-dryer combos, the garment handling equipment includes an outer drum 572 and an inner drum 571. The inner drum 571 is rotatably installed inside the outer drum 572. The inner drum 571 has multiple water passage holes. The garment drying chamber 540 includes an inner cavity 541 located inside the inner drum 571 and an outer cavity 542 located between the outer drum 572 and the inner drum 571. The garment loading / unloading port 530 is connected to both the inner cavity 541 and the outer cavity 542. The garments to be dried are contained in the inner drum 571. The bottom of the outer cavity 542 has a drain outlet connected to the drain pipe 560. The medium outlet 130 is connected to the outer cavity 542.

[0097] With this design, during the drying process, the inner drum 571 can rotate the clothes to be dried, allowing them to come into more thorough contact with the hot air and resulting in higher drying efficiency.

[0098] In some possible implementations, the lower edge of the condenser 100 is outside the inner cavity 541.

[0099] For example, in an embodiment where the medium cavity 110 is defined by the inner shell 552, the outer cover, and the door ring 551, the lower edge of the inner shell 552 is outside the inner cavity 541.

[0100] With this configuration, the condensate condensed on the surface of the condensing container 100 flows into the drain pipe 560 through the outer cavity 542 between the inner cylinder 571 and the outer cylinder 572, which facilitates the discharge of the condensate condensed on the surface of the condensing container 100. At the same time, it can prevent condensate from entering the inner cavity 541 and reducing the drying efficiency.

[0101] In some examples, the outlet of the condenser 521 of the condenser drying system is located in the outer cavity 542 between the inner drum 571 and the outer drum 572, and is connected to the drain pipe 560 through the outer cavity 542. This arrangement facilitates drainage and does not affect the drying efficiency of the clothes.

[0102] In some possible implementations, the water outlet of the water supply pipe 510 is located on the inner wall of the clothing loading and unloading port 530 and is spaced apart directly above the medium inlet 120. The water outlet of the water supply pipe 510 serves as the injection port 150 for injecting water into the medium inlet 120. The opening of the medium inlet 120 is greater than the opening of the injection port 150. When the liquid level in the medium cavity 110 reaches the preset liquid level, the elastic sleeve of the liquid level control valve 200 blocks the medium inlet 120, and the elastic cone plug of the liquid level control valve 200 blocks the water outlet of the water supply pipe 510.

[0103] Understandably, the injection port 150 faces the medium inlet 120 directly below it.

[0104] This design facilitates the setting and opening / closing of the sealing door 550, and makes it convenient, efficient and splash-proof for the injection port 150 to inject water into the medium inlet 120. Furthermore, when the liquid level in the medium chamber 110 reaches the preset liquid level, the liquid level control valve 200 can simultaneously block the outlet of the medium inlet 120 and the water supply pipe 510, preventing the water supply pipe 510 from continuing to supply water after the medium inlet 120 is blocked, thus avoiding water waste and an increase in the moisture content in the clothes drying chamber 540.

[0105] In some examples, a sealing ring 580 is provided at the clothing loading / unloading port 530, connecting the outer wall of the clothing handling device and the cavity wall of the clothing drying chamber 540. The sealing ring 580 serves as the inner wall of the clothing loading / unloading port 530, and the water outlet of the water supply pipe 510 passes through the sealing ring 580 from top to bottom. In embodiments with an inner cylinder 571 and an outer cylinder 572, the sealing ring 580 is located between the outer cylinder 572 and the outer wall of the clothing handling device, connecting the outer cylinder 572 and the outer wall of the clothing handling device. With this arrangement, water at the clothing loading / unloading port 530 can flow into the outer cavity 542 along the surface of the sealing ring 580.

[0106] Figure 7 This is a schematic diagram of the water distributor in an embodiment of the proposed garment processing equipment. Figure 7 and combined Figure 5 , Figure 6 As shown, in some possible embodiments, the garment processing equipment further includes a water distributor 600, and the drying system 520 is a condensing drying system. A water storage chamber 610 is formed inside the water distributor 600. A water inlet 620 is provided at the upper part of the water storage chamber 610. The water inlet 620 is used to communicate with the water supply equipment. A water distribution port 630 is provided on the side wall of the water storage chamber 610. The water distribution port 630 is connected to the water inlet end of the water supply pipe 510. The water inlet end of the water inlet pipe 524 of the condensing drying system extends into the water storage chamber 610. The water inlet end of the water inlet pipe 524 of the condensing drying system is connected to the water storage chamber 610. The water inlet end of the water inlet pipe 524 of the condensing drying system is above the water distribution port 630. The area of ​​the water inlet 620 is smaller than the area of ​​the water inlet end of the water inlet pipe 524 of the condensing drying system.

[0107] With this configuration, the water supplied through the inlet 620 is first depressurized in the water storage chamber 610 before being supplied to the water replenishment pipe 510 and the water inlet pipe 524 of the condensing drying system. This avoids excessive water pressure when the water replenishment pipe 510 is directly connected to the tap water pipe, which could cause splashing or prevent the water outlet of the water replenishment pipe 510 from being blocked. When the water level in the water storage chamber 610 reaches the inlet end of the water inlet pipe 524 of the condensing drying system, the water in the water storage chamber 610 flows into the inlet end of the water inlet pipe 524 of the condensing drying system. The inlet end of the water inlet pipe 524 of the condensing drying system can limit the water level in the water storage chamber 610, thereby limiting the pressure of the water entering the water replenishment pipe 510. In embodiments where the level control valve 200 includes a float 210 and a second sealing element 250, the situation where the second sealing element 250 fails to seal the outlet end of the water supply pipe 510 under the buoyancy of the float 210 can be avoided. Simultaneously, the size of the float 210 can be reduced. Furthermore, the area of ​​the water inlet 620 being smaller than the area of ​​the water inlet end of the condenser drying system's water inlet pipe 524 ensures that excess water can flow into the condenser drying system's water inlet pipe 524.

[0108] In some possible implementations, the inlet end of the water inlet pipe 524 of the condensing drying system faces upward, and the downward projection of the water inlet 620 includes a first region within the range of the inlet end of the water inlet pipe 524 of the condensing drying system and a second region outside the range of the inlet end of the water inlet pipe 524 of the condensing drying system, wherein the area of ​​the first region is larger than the area of ​​the second region.

[0109] With this configuration, most of the water flowing in through the inlet 620 enters the inlet pipe 524 of the condensing drying system, while a small portion is stored in the water storage chamber 610 and flows into the water supply pipe 510 through the water storage chamber 610. When the pressure of the water supplied from the inlet 620 is particularly high and the pressure relief capacity of the water storage chamber 610 alone is insufficient, pressure relief can be achieved through the inlet end of the inlet pipe 524 of the condensing drying system. The pressure relief effect is good, ensuring that the water pressure flowing into the water supply pipe 510 does not exceed the pressure generated by the water level at the inlet end of the inlet pipe 524 of the condensing drying system.

[0110] In some possible implementations, the air supply end of the drying system 520 is located on the side of the clothes drying chamber 540 where the clothes loading and unloading port 530 is located. The air supply end of the drying system 520 is located above the condenser container 100. The air supply direction of the air supply end of the drying system 520 is inclined downward and faces into the clothes handling equipment. The condenser container 100 is on the air supply path of the air supply end of the drying system 520.

[0111] With this configuration, the hot air delivered from the air supply end of the drying system 520 is first condensed on the surface of the condenser container 100 before coming into contact with the clothes, which can improve the condensation efficiency and make the air in the clothes drying chamber 540 drier, resulting in a better drying effect.

[0112] In some possible implementations, the air inlet of the drying system 520 is located on the side of the clothes drying chamber 540 opposite to the clothes loading / unloading port 530, and the air inlet of the drying system 520 is located at the upper part of the clothes drying chamber 540. This helps to improve the utilization efficiency of hot air.

[0113] For example, the air inlet and water outlet of the condenser 521 in the condensing drying system are both connected to the outer cavity 542 between the outer cylinder 572 and the inner cylinder 571 through an opening.

[0114] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
