[0046] The embodiments of the present application provide a treatment kit assembly and a clothes treatment device, which can improve the cleaning efficiency and clothes care effect of the clothes treatment agent, thereby providing a user with a better laundry experience.

[0047] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 a structural schematic view of the drying duct shell 11 and the treatment kit assembly 20 provided by the embodiments of the present application; Figure 2 a structural schematic view of the heating pipe 22 provided by the embodiments of the present application.

[0048] The clothes treatment device of the embodiments can be a washing machine, a dryer, a clothes care machine, etc., and the clothes treatment agent can be a detergent, a softener, a bleaching agent, etc. Hereinafter, the clothes treatment device of the embodiments will be described as a washing machine.

[0049] The clothes treatment device of the embodiments comprises a cabinet 10, a clothes treatment drum and a treatment kit assembly 20. The cabinet 10 comprises an outer shell and an internal support frame. The outer shell can be made of engineering plastic material, which has good insulation performance and impact resistance. The front of the outer shell is provided with a control panel for user operation. The control panel integrates a touch display screen or a plurality of operation buttons. The user can select various clothes treatment programs such as regular washing, strong stain removal, drying, steam care, etc. through the touch display screen or the operation buttons, and can also be used to start, pause, stop the program and adjust some basic parameters such as water level, temperature, etc.

[0050] The internal support frame is made of high-strength metal alloy material, which is stable in structure and can stably support the clothes treatment drum to ensure its stability during operation. The internal support frame and the outer shell can adopt shock absorption connection technology, thereby effectively reducing the vibration and noise generated by the clothes treatment device during operation.

[0051] The laundry treatment drum of the embodiment is installed in the cabinet 10, for example, on an internal support frame of the cabinet 10. The laundry treatment drum can be made of stainless steel material, which ensures sufficient strength to withstand the centrifugal force generated by high-speed rotation. The internal space of the laundry treatment drum can be laid out according to washing requirements, so as to accommodate different volumes and types of laundry to be washed, such as bed sheets, clothes, shoes, etc. The inner wall of the laundry treatment drum is treated to be smooth, which effectively reduces the wear of laundry during the washing process. The bottom of the drum body is provided with a drainage system for quickly draining sewage during the rinsing and draining stages, and is not easy to be blocked.

[0052] The treatment agent box assembly 20 of the embodiment includes a water inlet pipe 21, a treatment agent box 23, and a heating pipe 22. The water inlet pipe 21 can be made of silica gel hose, which has good flexibility and temperature resistance to adapt to different installation environments and water flow conditions. The connection end of the water inlet pipe 21 with the external water source adopts a universal standard interface, which is convenient for users to install and disassemble.

[0053] The treatment agent box 23 is made of high-strength plastic material, and can also be made of transparent material, which is convenient for users to observe the remaining amount of the treatment agent at any time. The inside of the treatment agent box 23 can be divided into multiple independent compartments for storing different types of laundry treatment agents, such as detergents, softeners, bleaching agents, etc.

[0054] The heating pipe 22 of the embodiment is a key component for realizing the cleaning efficiency of the laundry treatment agent. Specifically, the heating pipe 22 has a water inlet interface 223 and a water outlet interface 224. The water inlet interface 223 is connected with the water inlet pipe 21, and the water outlet interface 224 is in communication with the inner cavity of the treatment agent box 23. Exemplarily, the water inlet interface 223 of the heating pipe 22 is connected with the water inlet pipe 21 through threads, which ensures firm connection and no water leakage. The water outlet interface 224 is connected with the inner cavity of the treatment agent box 23 in a sealed manner to prevent hot water leakage.

[0055] Further, the heating pipe 22 includes an inner pipe 225 and a heating coating 226 arranged on the outer wall of the inner pipe 225. The inner pipe 225 is made of metal material with excellent heat conduction performance, such as copper pipe, aluminum, etc. The copper pipe has high thermal conductivity, which can quickly transfer heat to the water inside, so that the water is quickly heated. The inner wall of the inner pipe 225 is treated to be smooth to reduce water flow resistance and ensure that the water can flow smoothly through the heating pipe 22.

[0056] The heating coating 226 can be made of nano-level electrothermal material, such as a coating formed by mixing antimony tin oxide (ATO) nanoparticles and an organic binder. Such nano coating has good electrothermal conversion performance, which can quickly generate heat and uniformly transfer the heat to the inner pipe 225 when the current passes through.

[0057] As some of the embodiments, the heating pipe 22 can be a resistance wire heating pipe, and the resistance wire can be made of nickel-chromium alloy material, which can quickly generate a large amount of heat when powered on. The resistance wire is wound on the outer wall of the inner pipe 225, and an insulating and heat-conducting material such as magnesium oxide powder is filled between the resistance wire and the inner pipe 225, which can not only ensure the insulation safety between the resistance wire and the inner pipe 225, but also effectively transfer the heat generated by the resistance wire to the inner pipe 225, thereby improving the heating efficiency.

[0058] The heating pipe 22 can also be a thick film heating pipe. The heating element of the thick film heating pipe is a thick film heating material, which is mainly formed by printing an electrically conductive paste composed of metals such as silver and palladium and glass frit on the outer wall of the inner pipe 225. Silver has good electrical conductivity and can generate heat when powered on, and palladium can improve the stability and oxidation resistance of the heating material. The glass frit plays a role in bonding and insulation, bonding the conductive particles together and preventing current leakage.

[0059] The heating pipe 22 can also be a nano-coating heating pipe. The nano-coating of the nano-coating heating pipe is made of metal oxide, such as titanium dioxide nano-coating. Titanium dioxide has good electrical conductivity and electrical heating conversion performance under certain conditions. The nano-coating is coated on the outer wall of the inner pipe 225 by advanced processes such as chemical vapor deposition (CVD) or physical vapor deposition (PVD), forming a uniform and dense coating. Such a nano-coating heating pipe 22 has the advantages of fast heating speed, good heating uniformity, energy saving and environmental protection, etc.

[0060] When the user selects a washing or care program on the control panel and starts the clothes treatment device, tap water flows into the heating pipe 22 along the water inlet pipe 21 under the action of water pressure. At this time, the heating pipe 22 is powered on and converts electrical energy into heat energy, rapidly heating the tap water in the heating pipe 22. The heated hot water flows into the inner cavity of the treatment agent box 23 through the water outlet interface 224. In the treatment agent box 23, the hot water is fully mixed with the pre-placed treatment agent. Due to the increase in temperature of the hot water, the active ingredient molecules in the treatment agent obtain more energy, and the molecular motion becomes more violent. Taking the detergent as an example, the surfactant molecules in it can penetrate into the pores of the clothes fibers faster at high temperatures, and have more effective chemical reactions with the stain molecules, decomposing and peeling off the stains from the clothes. As for the softener, its care ingredients can also better combine with the clothes fibers at high temperatures to form a protective film, making the clothes more soft and smooth, and reducing static electricity. In this way, after the treatment, the clothes not only become cleaner and more tidy, but also have obvious improvement in softness, color retention, etc., improving the user's experience.

[0061] The clothes treatment device of the present embodiment also includes a drying duct shell 11. By reasonably arranging the heating pipe 22 in the drying duct 101, the functions of heating tap water and air in the drying duct 101 are realized, thereby improving the activity of the clothes treatment agent and improving the drying efficiency and quality.

[0062] Specifically, the interior of the drying duct shell 11 can be made of a heat-insulating material, such as a high-temperature-resistant ceramic fiber material, glass fiber, etc., to reduce the heat loss outside the drying duct 101 and improve the heat utilization rate. The internal structure of the drying duct shell 11 can be designed to be streamlined to guide the smooth circulation of hot air in the drying duct 101, reduce air flow resistance, and thus improve drying efficiency. The drying duct 101 can be directly connected with the clothes treatment drum, or connected through a ventilation duct made of flexible and high-temperature-resistant material to adapt to the slight displacement and vibration of the clothes treatment drum during operation, and ensure that the ventilation connection between the drying duct 101 and the clothes treatment drum is always stable and reliable.

[0063] The heating pipe 22 is partially accommodated in the drying duct 101, or the entire heating pipe 22 is accommodated in the drying duct 101. During the washing program, tap water enters the inner pipe 225 of the heating pipe 22 under the action of water pressure, the heating coating 226 of the heating pipe 22 is powered to generate heat, and the water in the inner pipe 225 is heated, and the hot water flows into the treatment agent box 23 to mix with the clothes treatment agent to form washing water. After the clothes treatment agent is activated, the washing water enters the clothes treatment drum for washing. When the drying program is started, the heating pipe 22 continues to be powered to heat the air in the drying duct 101, and the hot air circulates between the drying duct 101 and the clothes treatment drum to remove the moisture of the clothes and further play the care and sterilization role of the clothes treatment agent.

[0064] By skillfully arranging the heating pipe 22 in the drying duct 101, the integration of the promotion of the activity of the clothes treatment agent in the washing process and the rapid drying and care function of the clothes in the drying process is realized, and the space and cost are saved.

[0065] Further, in order to improve the drying efficiency, the drying duct 101 of the embodiment adopts a skillful structural design.

[0066] Specifically, the drying duct 101 has an air inlet 102 and an air outlet 103. The air inlet 102 is communicated with one side of the clothes treatment drum to suck in the air of the clothes treatment drum. The air outlet 103 is communicated with the other side of the clothes treatment drum, so that the hot air can enter the clothes treatment drum to dry the clothes. In this way, the air circulation between the drying duct 101 and the clothes treatment drum is realized.

[0067] The width of the drying duct 101 gradually increases in the direction from the air inlet 102 to the air outlet 103. Based on the principle of aerodynamics, when the fan blows air into the drying duct 101 from the air inlet 102, the air flow rate gradually decreases and the pressure gradually increases with the gradual increase of the width of the drying duct 101, so that the hot air can be blown out more uniformly from the air outlet 103 and fully contact the clothes, thereby improving the drying efficiency.

[0068] The heating pipe 22 is arranged at one end of the drying channel 101 close to the air outlet 103. This arrangement allows the air to flow fully in the drying channel 101 after being accelerated by the fan, and then be heated by the heating pipe 22. This can avoid the uneven distribution of heat and waste of energy caused by the heating pipe 22 heating the air too early.

[0069] The fan is arranged at one end of the drying channel 101 close to the air inlet 102. The fan in this embodiment is a centrifugal fan. The function of the fan is to form a stable air circulation in the drying channel 101, to quickly suck the air in the clothes treatment drum into the drying channel 101 and make it flow at high speed in the drying channel 101. The high-speed operation of the fan can make the air quickly fill the drying channel 101 and form a certain pressure difference in the drying channel 101, so as to make the air flow from the air inlet 102 to the air outlet 103, and then into the clothes treatment drum, to take away the moisture in the clothes, and achieve the drying purpose.

[0070] In order to improve the heating efficiency of the heating pipe 22 on the water inside it, the heating pipe 22 in this embodiment is arranged in a meandering and curved shape.

[0071] Specifically, the heating pipe 22 is in a meandering and curved shape, and the curved part adopts a smooth circular arc transition. For example, the heating pipe 22 can be connected by bending a plurality of straight pipes in sequence, forming a structure similar to a snake. The above-mentioned meandering and curved shape increases the contact area of the heating pipe 22 and water. When the water flows in the heating pipe 22, more water molecules can contact the pipe wall of the heating pipe 22, thereby more fully absorbing heat and improving the heating efficiency.

[0072] Further, the heating pipe 22 includes a first pipe body 221 and a second pipe body 222 which are arranged in a stack and are in communication with each other. The first pipe body 221 is connected to the water inlet 223, and the second pipe body 222 is connected to the water outlet 224. The first pipe body 221 and the second pipe body 222 arranged in a stack not only improve the water storage capacity of the heating pipe 22, but also increase the contact area with water again. In the heating process, more water can be heated and store a certain amount of heat. When the treatment agent is mixed with hot water, it can continuously provide stable heat, so that the activity of the clothes treatment agent is more fully excited, thereby improving the cleaning and care effect of the clothes.

[0073] Further, the water inlet interface 223 and the water outlet interface 224 are located on the same side of the heating pipe 22. Exemplarily, the water inlet interface 223 is connected to the water inlet pipe 21 in a threaded manner, and a filter screen is arranged at the interface to prevent impurities in the water from entering the heating pipe 22. The water outlet interface 224 is also connected to the connecting pipe of the treatment agent box 23 in a threaded manner, and a good seal is achieved. The above-mentioned interface layout on the same side facilitates the pipe connection operation, and during installation, workers do not need to perform connection work on both sides of the heating pipe 22, thereby reducing the installation difficulty and time. At the same time, during maintenance, the interface can be conveniently checked, repaired or replaced, thereby improving the maintenance efficiency. Moreover, the interface layout on the same side makes the installation of the heating pipe 22 in the device more compact, thereby saving installation space.

[0074] In some embodiments, the water outlet pipe 24 is further included in the treatment agent box assembly 20, and a temperature sensor is arranged to monitor and control the water temperature, so as to optimize the activation effect of the treatment agent and improve the treatment quality of the clothes, while protecting the material of the clothes.

[0075] Specifically, one end of the water outlet pipe 24 is connected to the water outlet interface 224, and the other end is in communication with the inner cavity of the treatment agent box 23. The water outlet pipe 24 can be made of a plastic pipe material that is resistant to high temperature and corrosion, and the inner diameter thereof is designed according to the required water flow, so as to ensure smooth water flow and avoid too rapid water temperature drop due to excessively large pipe diameter. The length of the water outlet pipe 24 can be determined according to the relative position of the treatment agent box 23 and the heating pipe 22.

[0076] The temperature sensor can be arranged on the heating pipe 22, on the water outlet pipe 24, or on both the heating pipe 22 and the water outlet pipe 24. When the temperature sensor is arranged on the heating pipe 22, a contact type temperature sensor such as a thermocouple or a thermal resistance sensor can be used. The temperature sensor is installed on the heating pipe 22, such as near the outlet of the heating pipe 22 or in the middle of the heating pipe 22, so as to accurately sense the temperature change of the water in the heating pipe 22. When the temperature sensor is arranged on the water outlet pipe 24, a non-contact type temperature sensor such as an infrared temperature sensor can be used. The infrared temperature sensor calculates the temperature of the water in the pipe by detecting the infrared radiation intensity of the surface of the water outlet pipe 24, and has the advantages of not being in direct contact with the water, avoiding corrosion and pollution of the sensor, and fast response speed. If the temperature sensor is arranged on both the heating pipe 22 and the water outlet pipe 24, double monitoring of the water temperature can be achieved, thereby improving the accuracy and reliability of temperature measurement. The temperature sensor transmits the detected temperature signal to the control system of the clothes treatment device, the control system compares and analyzes the temperature according to the preset temperature parameter, and then adjusts the heating power of the heating pipe 22, so as to ensure that the water temperature reaches and maintains in the optimal treatment agent activation temperature range.

[0077] The laundry treating device of the embodiment also has a pre-washing function. Specifically, the inner cavity of the treating agent box 23 comprises a treating agent cavity and a pre-washing cavity which are not communicated with each other, the treating agent cavity is used for storing treating agents required in a normal washing process, such as washing agent, softening agent, etc., and the inlet of the treating agent cavity is connected with the water outlet pipe 24.

[0078] The pre-washing cavity is specially used for storing treating agents required in a pre-washing process, such as pre-washing agent or a small amount of high-concentration washing agent. The pre-washing cavity is communicated with an external water source through a pre-washing pipe 25, one end of the pre-washing pipe 25 is connected with the inlet of the pre-washing cavity, and the other end is used for communicating with the external water source. When the laundry treating device starts a pre-washing program, the control panel controls the pre-washing pipe 25 to be in a conducting state according to the parameters set by the user, water enters the pre-washing cavity through the pre-washing pipe 25 and mixes with the pre-washing agent, and the water mixed with the pre-washing agent enters the laundry treating drum. The laundry to be washed performs a preliminary tumbling motion in the drum, and the pre-washing agent starts to act on the stains on the laundry, decomposes and softens part of the stains. After the pre-washing program ends, the sewage is discharged.

[0079] The treating agent box assembly 20 of the embodiment controls the on-off of the water inlet pipe 21 and the pre-washing pipe 25 through a valve assembly 26.

[0080] In one embodiment, the valve assembly 26 comprises a first valve 261 and a second valve 262. The first valve 261 is connected with the end of the water inlet pipe 21 away from the heating pipe 22, and can adopt an electromagnetic valve, a mechanical ball valve, etc. The first valve 261 of the embodiment adopts an electromagnetic valve, and is mainly used for controlling the on-off of the water inlet pipe 21 and controlling the flow of the water inlet pipe 21. For example, in a main washing program, the water flow of the water inlet pipe 21 can be adjusted according to the amount of laundry and the requirement of treating agent, so as to meet different washing requirements.

[0081] The second valve 262 is connected with the end of the pre-washing pipe 25 away from the treating agent box 23, and can also adopt an electromagnetic valve, a mechanical ball valve, etc. The second valve 262 of the embodiment adopts an electromagnetic valve, and is mainly used for controlling the on-off of the pre-washing pipe 25 and controlling the flow of the pre-washing pipe 25. When the pre-washing program starts, the second valve 262 is opened according to the instruction of the control panel, the pre-washing pipe 25 is in a conducting state, and water enters the pre-washing cavity through the pre-washing pipe 25 and mixes with the pre-washing agent.

[0082] In another embodiment, the valve assembly 26 comprises a three-way valve which is connected to both the water outlet pipe 24 and the pre-washing pipe 25. The three-way valve in this embodiment is an electrically operated three-way switching valve. During the pre-washing process, the three-way valve directs the water from the external water source to the pre-washing pipe 25, while the flow rate and pressure of the water can be controlled so that the water mixes with the pre-washing agent in the pre-washing chamber in a suitable ratio before entering the clothes treatment drum, so as to meet the pre-washing requirements of different levels of stains. During the main washing process, the three-way valve switches to direct the water from the external water source to the water inlet pipe 21, and the water is heated by the heating pipe 22 before mixing with the treatment agent and then flowing into the clothes treatment drum to achieve the main washing function. The electrically operated three-way switching valve has the advantages of simple structure, easy operation and rapid switching, and can improve the working efficiency and reliability of the entire treatment agent cartridge assembly 20.

[0083] The above merely provides the preferred embodiments of the present application, but not for the purpose of limiting the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
