Description

Technical Field

[0001] The present application belongs to the technical field of washing and drying machines, and specifically relates to a washing and drying machine delivery component and a control method thereof, and a washing and drying machine having the same. Background Art

[0002] During the use of the washing and drying machine, the automatic dispensing system is often used to accurately dispense detergent and softener according to the weight and type of clothing. However, when the washing and drying machine is in the drying process, due to the high temperature drying, the detergent and softener are easy to evaporate during this process, causing them to become viscous, which may reduce the cleaning efficiency and even block the dispensing pipe, affecting the normal operation of the machine. Characteristics of detergents and softeners: Some detergents and softeners have a high viscosity themselves, but they may become thicker under high or low temperature conditions. High-viscosity liquids flow slowly when passing through the dispensing system, and are prone to form residues on the inner wall of the pipes and the dispensing container, which will cause pipe blockage or poor cleaning effect over time.

[0003] The physical properties of detergents and softeners will change under different temperature environments. If the temperature in the washing machine is too low, the movement speed of water molecules in detergents and softeners will slow down, which will lead to a decrease in the solvation ability of water for surfactant molecules, that is, the interaction between water molecules and surfactant molecules will be weakened. Therefore, the attraction between surfactant molecules is relatively enhanced, causing them to be more inclined to gather together to form larger molecular clusters, thus making the detergent viscous. In addition, some additives in detergents may also precipitate or solidify at low temperatures, further increasing the viscosity of the detergent. For example, some non-ionic surfactants are easy to crystallize at low temperatures, causing the product to thicken; conversely, if the temperature is too high, it may accelerate its evaporation, resulting in an increase in concentration, which will also increase the viscosity. Summary of the invention

[0004] Therefore, the present application provides a washing and drying machine dispensing component and a control method thereof and a washing and drying machine having the same, which can solve the problem in the prior art that detergents and softeners in the washing and drying machine lose moisture due to the drying state of the washing and drying machine, forming residues on the inner walls of the pipes and the dispensing container, which may cause pipe blockage or poor cleaning effect over time.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0023] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".

[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0025] See also Figures 1 to 3 As shown, according to an embodiment of the present application, a washing and drying machine delivery assembly includes: The delivery cavity 1 can accommodate a box containing detergent or softener; A heat exchange tube 14 is provided on the side wall of the delivery cavity 1, and a heat exchange agent is provided in the heat exchange tube 14; the outer wall of the heat exchange tube 14 is attached to the inner wall of the side wall to conduct away the heat transferred into the delivery cavity 1 through the side wall.

[0026] The traditional washing and drying machine dispensing structure includes a dispensing chamber 1 and a movable pull-out box body. The box body is located in the dispensing chamber 1 and can be pulled out to fill detergent or softener. The box body is provided with multiple compartments for placing washing powder, laundry liquid, softener and other consumables, so as to facilitate the introduction of water into the washing chamber during washing.

[0027] The present application uses a heat exchange tube 14 containing a heat exchange agent on the side wall of the delivery chamber 1 to promptly conduct away the heat transferred to the delivery chamber through the side wall, thereby achieving the beneficial effect of effectively reducing the loss of water in the detergent or softener in the drying state of the washing and drying machine.

[0028] A heat exchange tube 14 is arranged on the side wall, so that when the washing machine is in the drying program, the heat transferred to the side wall by the hot air can be promptly conducted away by the heat exchange tube 14, thereby reducing the heat transferred to the detergent or softener in the delivery chamber 1. This ensures that the moisture in the detergent or softener is not easily lost, maintains the fluidity of the detergent or softener, and prevents the lost moisture from forming residues on the inner wall of the pipeline and the delivery container, which will cause pipeline blockage or poor cleaning effect over time.

[0029] In the internal structure of a traditional washing and drying machine, the box for holding detergent or softener also has the problem of condensation, which is also a common technical problem. Since the washing and drying machine is dried after washing, the internal humidity is usually high before drying. In such a humid environment, when the drying program is started, the temperature inside the washing and drying machine is usually high. Combined with the box body being placed in the delivery chamber 1 in a pull-out manner, the temperature is not much different from the external environment, and is lower than that inside the washing and drying machine. This causes the water vapor inside the washing and drying machine to quickly cool and condense into water droplets when it contacts the side wall of the delivery chamber 1 with a lower temperature, forming condensation. The condensation generated on the side wall of the delivery chamber 1 may cause electrical components to become damp, increasing the risk of short circuits and electrical failures. In addition, long-term condensation and water droplet accumulation will corrode the delivery box and surrounding metal parts, shorten the service life of the washing and drying machine, and cause inconvenience to users when using it, such as water droplets dripping and odors.

[0030] Since the present application sets a heat exchange tube 14 on the side wall, it is equivalent to widening the structure of the side wall. The heat exchange tube 14 blocks the contact between the high temperature of the washing and drying machine and the low temperature components in the delivery chamber 1. This can reduce the occurrence of condensation, prevent condensation dripping inside the machine body from causing safety problems in use, and increase the service life of the washing and drying machine.

[0031] The present application merely adds a heat exchange tube 14 structure to the side wall of the delivery chamber 1 in the conventional washing and extracting machine, without modifying other components, and has wide applicability.

[0032] The heat exchange agent, including water, transmitted in the heat exchange tube 14 takes away the heat transferred to the side wall of the delivery chamber 1 through the flow of the heat exchange agent, thereby reducing the heating of the box body in the delivery chamber 1 and the detergent or softener therein, thereby preventing the detergent or softener from losing moisture and forming residual blocks in the pipe and the inner wall of the box body.

[0033] The heat exchange tubes 14 can be arranged in an intermittent or close arrangement, both of which can promptly guide away the heat on the side wall and prevent the side wall from absorbing heat and then dissipating it to the box body.

[0034] In some embodiments, The heat exchange tube 14 is configured to be composed of a single tube reciprocating coil.

[0035] The heat exchange tube 14 is constructed by a single-tube reciprocating coil, which facilitates the transmission of heat exchange agent into the heat exchange tube 14, that is, only one inlet and one outlet are required to complete the heat exchange function; combined with the fact that the washing and drying machine itself is equipped with a washing transmission pipeline, the single-tube heat exchange tube 14 is conveniently connected to the water injection and water outlet of the washing and drying machine to achieve the effect of taking away heat.

[0036] In some embodiments, The heat exchange tube 14 is disposed on at least two side walls of the delivery chamber 1 .

[0037] like Figure 2 and Figure 3 As shown, the front and back sides of the delivery chamber 1 are usually not easily exposed to the hot air of the washing and drying machine, and the heat exchange tube 14 is arranged on the three side walls of the delivery chamber 1 which are connected in sequence. According to the actual structural conditions, the side walls of the delivery chamber 1 which are easily exposed to the hot air can be provided with the heat exchange tube 14 to timely guide away the transferred heat.

[0038] In some embodiments, The side wall comprises a heat insulating layer made of heat insulating material.

[0039] As for the structure of the side wall, in order to further prevent heat conduction into the delivery chamber 1, the side wall itself can be made of a heat-insulating material, so that heat is difficult to transfer in. Combined with the heat exchange tube 14 arranged on the inner surface of the side wall, even if the heat is transferred, it will be conducted away in time, thereby reducing the evaporation of water in the detergent or softener; in addition, the side wall of the heat-insulating material can also reduce the generation of condensation on the side wall of the delivery chamber 1 due to its poor heat transfer effect.

[0040] In some embodiments, The side wall comprises at least two layers which are stacked together: an outer layer comprises a heat insulating layer, and an inner layer comprises a leakproof layer.

[0041] The side wall can also be set as a multi-layer insulation structure, such as a stacked outer insulation layer and an inner leak-proof layer, which can also effectively block heat transfer and prevent moisture evaporation inside the box and condensation formation on the outer wall.

[0042] According to another aspect of the present application, a control method for the above-mentioned washing and drying machine delivery assembly is provided, comprising: When the washing and drying machine runs the drying program, the heat exchange agent is simultaneously transmitted to the heat exchange tube 14; the hot air used by the washing and drying machine for drying heats the side wall of the delivery chamber 1, and the heat exchange agent can conduct away the heat on the side wall of the delivery chamber 1.

[0043] When the drying program of the washing and drying machine is running, a large amount of hot air will be generated. At this time, the side wall of the delivery chamber 1 is in a heated state, and the heat exchange agent is transmitted to the heat exchange tube 14 at the same time, which can timely guide the heat transferred to the delivery chamber 1 to avoid the air in the delivery chamber 1 being heated and causing the evaporation of water in the detergent or softener.

[0044] In some embodiments, When the washing machine runs a washing program, the heat exchange agent is stopped from being transmitted into the heat exchange tube 14 , and the heat exchange agent residing in the heat exchange tube 14 can block the heat from entering the delivery chamber 1 through the side wall.

[0045] When the washing machine is in the washing program, the heat exchange agent is stopped from being transported to the heat exchange tube 14, that is, the heat exchange agent is in a stopped flow state, but at this time the residual heat exchange agent in the heat exchange tube 14 plays a role of heat insulation.

[0046] According to another aspect of the present application, a washer-dryer is provided, comprising the washer-dryer delivery assembly as described above, or the washer-dryer delivery assembly operated according to the control method as described above.

[0047] In some embodiments, One end of the heat exchange tube 14 is connected to the water inlet pipe of the washing and drying machine, and the other end is connected to the drain pipe of the washing and drying machine.

[0048] One end of the heat exchange tube 14 is connected to the water inlet pipe of the washing and drying machine to realize the automatic water filling function, and the other end can flow out into the washing tub, and can also be connected to the drain pipe of the washing and drying machine to be directly discharged.

[0049] The present application directly utilizes the water supply and drainage of the washing and drying machine itself to connect the heat exchange pipe 14, without the need to set up an additional water supply and drainage structure, and has a simple structure and is easy to disassemble and assemble.

[0050] In some embodiments, The box body is movably arranged in the delivery cavity 1 .

[0051] The box for containing detergent or softener needs to be pulled out to add detergent or softener, so it is set as a movable structure.

[0052] like Figure 1As shown, a washing powder box 2 and a detergent and softener box 5 are arranged in the delivery chamber 1, and a water injection channel 3 is arranged in the body above the washing powder box 2. Water is transmitted from the water injection port 31, and the water outlet 32 ​​is located above the washing powder box 2, so that the washing powder in the washing powder box 2 is flushed and flows into the washing drum; and the detergent and softener box 5 is connected to the delivery pump 4, and the delivery pump 4 transmits the detergent and softener to the water injection channel 3 downstream of the water injection port 31, and the detergent and softener flow into the washing drum with the water flow. Washing powder, detergent and softener need to be frequently replenished due to consumption during use, so the washing powder box 2 and the detergent and softener box 5 are pull-out arranged in the delivery chamber 1.

[0053] Most washing and drying machines are condensing washing and drying machines. Under normal circumstances, the temperature of the condensing washing and drying machine rises during drying. After encountering the low-temperature delivery chamber 1, the water vapor in the air condenses to form water. This process occurs continuously during the drying process. Therefore, after a period of time, the water around the delivery chamber 1 is easy to penetrate outward along the delivery chamber 1. The detergent and softener box 5 in the delivery chamber 1 is not completely closed even if there is a cover. When the washing and drying machine starts drying, the water in the detergent and softener box 5 begins to evaporate slowly. The internal pressure is greater than the external pressure, and the water penetrates from the cover to the outside. However, due to the limited pressure difference, the opening angle of the detergent and softener box 5 cover is limited. If condensation occurs in the delivery chamber 1, the formed water is difficult to enter the detergent and softener box 5 through the cover, so that the water content of the detergent and softener is getting less and less after drying.

[0054] The washer-dryer dispensing assembly and the washer-dryer of the present application are mainly used to block heat from entering the detergent or softener box, to prevent the detergent and softener box 5 from solidifying during the drying process, which may cause blockage of the detergent or softener box and the automatic dispensing pipe, affecting the automatic dispensing of detergent and softener, and also to prevent the washing effect from being deteriorated due to the solidification of detergent and softener. Therefore, a method including a condensation water pipe passing through the side wall of the dispensing chamber 1 is adopted to achieve the purpose of blocking heat transfer.

[0055] In the method of using the condensation water pipe to pass through the side wall of the delivery chamber 1, since the detergent or softener box needs to be pulled out, the side wall of the delivery chamber 1 that is easily exposed to high temperature usually has three sides, so the condensation water pipe can be set in three directions of 270 degrees, such as Figure 2 and Figure 3 As shown, the front of the delivery chamber 1 is connected to the external environment, the top is a water injection channel 3, and the innermost side wall is in contact with the delivery pump 4. There is no need to set a condensation water pipe. This can ensure that the purpose of absorbing the heat around the delivery chamber 1 is achieved to the maximum extent. At the same time, it can reduce the safety and service life problems caused by condensation caused by the collision between the high temperature in the washing drum and the low temperature in the delivery chamber 1.

[0056] When the washer-dryer starts drying, the temperature inside the washer-dryer continues to rise due to the internal fan continuously sending hot air. Although only the clothes in the drum are heated during the heating process and no condensed water is generated, as the temperature continues to rise, the demand for moisture in the air in the drum continues to increase. Detergents and softeners contain a large amount of active substances, which can significantly reduce the surface tension of water. When the temperature rises, the evaporation rate of water will be faster. Therefore, the moisture in the detergent and softener is easily carried away by the air, causing the detergent and softener to become viscous. Passing the condensed water pipe through the side wall of the delivery chamber 1 can absorb most of the heat passing through the delivery chamber 1, effectively reducing the temperature in the delivery chamber 1, and effectively reducing the loss of moisture in the detergent and softener.

[0057] Most washing and drying machines are condensing washing and drying machines. The condensing water pipe used can be discharged together with the condensing water and drainage of the condensing washing and drying machines from the drain pipe and water pump, without the need to add additional drain pipes. However, the effect will change according to the outdoor temperature and water temperature. When the outdoor temperature is high, the tap water temperature will normally be higher than the normal environment. The difference between the temperature in the drum and the condensing water temperature is small, and the heat absorbed will be lower than when the outdoor temperature is lower.

[0058] Therefore, a certain amount of water is stored in the condensation water pipe after drying is completed. When the temperature is high in summer, it can prevent the evaporation of water in the detergent and softener due to the high ambient temperature when not in use. In addition, when the washing and drying machine is not used for a long time but there are detergents and softeners inside, the water in the condensation water pipe can also effectively alleviate the evaporation of its water and cause it to become viscous and block the pipes. When the detergent and softener become viscous, their activity is reduced, and they are not only easy to adhere to clothes, but also the cleanliness of the laundry will be reduced. It is easy for technicians in this field to understand that the above-mentioned embodiments can be freely combined and superimposed without conflict.

[0059] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
