DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the existing technology, as people's quality of life improves, clothes dryers gradually come into people's sight. According to the working principle, clothes dryers can be divided into exhaust type, air condensation type and heat pump type. Heat pump type clothes dryers do not need heaters to heat, and realize internal heat transfer through the heat pump system, with almost no heat loss to the outside. Therefore, compared with the other two types, the energy utilization rate is higher and more energy-saving.

[0030] However, the condenser and evaporator used for heat exchange in the heat pump system of a traditional heat pump dryer are directly placed on the base. A ventilated cavity is formed by closing an upper cover on the base. When working, the wind pressure in the cavity is relatively high, which makes the assembly of the upper cover and the base easy to loosen, causing air leakage and poor circulation effect, and even affecting the drying efficiency of the dryer.

[0031] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present application, a base assembly 10 is disclosed, which is used for a clothes dryer, and includes a bottom plate 11, a cover plate 12 and a fixing member 14, wherein the cover plate 12 is arranged on the bottom plate 11; an air duct 13 with openings at both ends is formed between the cover plate 12 and the bottom plate 11; an evaporator 20 and a condenser 30 of the clothes dryer are sequentially arranged in the air duct 13 along the air inlet direction of the air duct 13; the fixing member 14 is assembled with the bottom plate 11 and the cover plate 12 at the same time, and is used to make the cover plate 12 and the bottom plate 11 have an interference fit.

[0032] The base assembly 10 disclosed in the present application is formed by the cover plate 12 and the bottom plate 11 covering and cooperating to form an air duct 13. Both ends of the air duct 13 are connected to the inner cavity of the dryer. An evaporator 20 and a condenser 30 are arranged in the air duct 13, and a fan is used to blow air into the air duct 13 to circulate the air in the inner cavity of the dryer. In order to resist the wind pressure in the air duct 13 during the air circulation process, a fixing member 14 is arranged to assemble the cover plate 12 and the bottom plate 11 at the same time, so that the cover plate 12 and the bottom plate 11 are interference-fitted, that is, the cover plate 12 and the bottom plate 11 are squeezed against each other, thereby reducing the gap at the contact position between the cover plate 12 and the bottom plate 11, increasing the overall air tightness of the air duct 13, and improving the sealing effect. During the circulation process, the heat of the air heated by the condenser 30 can be more efficiently transferred to the inner cavity of the dryer, thereby maintaining the good performance of the dryer. In addition, the fixing member 14 forms a stable connection between the cover plate 12 and the bottom plate 11, which is conducive to maintaining the stability of the dryer structure and long-term use.

[0033] Specifically, as an implementation of this embodiment, the bottom plate 11 and the cover plate 12 are both plastic foam parts. First, there are many pores formed inside the plastic foam part, which increases its heat insulation performance, so when the heat pump system is working, the air duct 13 can be better insulated, and the overall heat loss of the dryer is reduced, which is conducive to improving the drying efficiency.

[0034] Second, the internal porous structure also has good ductility and cushioning properties. When the fixing part 14 assembles the base plate 11 and the cover plate 12 together, the interference fit of the cover plate 12 and the base plate 11 is more closely in contact, and the protrusions or depressions on the contact surface are smoothed, which can form a better sealed air duct 13, which is conducive to reducing air leakage, making the air circulation speed faster, and improving the drying speed of the dryer.

[0035] Third, in this embodiment, the bottom plate 11 and the cover plate 12 need to form a hollow air duct 13, and also need to match the shapes of the evaporator 20 and the condenser 30, so the shapes are relatively irregular; the plastic foam parts are manufactured by microporous foaming molding technology. During the processing, gas is introduced into the molten raw material to form a mixed sol, which can reduce the viscosity of the glue liquid. The filling effect is good during the injection process into the cavity, so irregularly shaped components can be better formed. In this embodiment, the production yield of the bottom plate 11 and the cover plate 12 can be improved.

[0036] Fourth, in the process of microbubble molding, the volume of the mixed sol is increased by filling gas, which has the advantages of saving raw materials, improving dimensional accuracy, and improving the internal stress distribution of components. Compared with traditional components, such as plastic parts, metal parts, etc., plastic foam parts are lighter in weight and easier to transport while maintaining a certain structural strength.

[0037] Fifth, the bottom plate 11 and the cover plate 12 can be made of the same raw material and in the same molding method, so that the manufacturing method of the base assembly 10 is simpler and the production cost is reduced.

[0038] Specifically, as an implementation of this embodiment, three chambers are sequentially formed in the air duct 13, and the evaporator 20, condenser 30 and fan 80 of the clothes dryer are respectively arranged in the three chambers. The air passes through the cavity of the evaporator 20, the cavity of the condenser 30 and the cavity of the fan 80 in sequence, and changes from humid cold air to dry hot air, so that the clothes can be dried.

[0039] like Figure 1 As shown, as another implementation of this embodiment, it is disclosed that the fixing member 14 is a screw, the cover plate 12 is provided with a limiting through hole, the base plate 11 is provided with a threaded hole at a position corresponding to the limiting through hole, the screw is installed in the limiting through hole and is screwed with the threaded hole. First, the screw connection method is stable. In the present embodiment, the base plate 11 and the cover plate 12 are interference fit, and the screws cooperate with the threaded holes to generate a mutual squeezing force between the base plate 11 and the cover plate 12, which will naturally be subject to a reaction force. The screw connection method can well resist this reaction force, prevent the screws from falling off from the threaded holes, maintain the stability of the structure of the base plate 11 and the cover plate 12 during the use of the base assembly 10, and maintain the sealing effect of the air duct 13; secondly, the depth of the threaded hole can be set to be greater than the length of the screw, so that after the base plate 11 and the cover plate 12 are in contact, the screw can be continuously screwed in to achieve an interference fit between the base plate 11 and the cover plate 12. The operation method is simple and the effect of achieving the interference fit is good; finally, the screw connection is simple to install and disassemble. During the service life of the dryer, when replacing or repairing the base plate 11, the cover plate 12, the evaporator 20, the condenser 30 and other components, the air duct 13 can be quickly opened to save assembly time.

[0040] In another embodiment, a plurality of screws and a matching number of threaded holes and limit through holes may be provided; the plurality of screws are evenly distributed along the edge of the cover plate 12, so that each position of the cover plate 12 is firmly connected to the base plate 11, forming a stable connection relationship.

[0041] like Figure 3 and Figure 4As shown, as another implementation of this embodiment, it is disclosed that the surface where the base plate 11 contacts the cover plate 12 is provided with a tortuous recessed pattern 111; the position on the cover plate 12 opposite to the recessed pattern 111 is provided with a tortuous raised pattern 121, and the raised pattern 121 is sealed and connected to the recessed pattern 111. By cooperating with the recessed pattern 111 and the raised pattern 121, firstly, the contact area between the bottom plate 11 and the cover plate 12 is increased, and the mutual limitation between the bottom plate 11 and the cover plate 12 is increased, so that the bottom plate 11 and the cover plate 12 cannot slide relative to each other; secondly, even if the wind pressure in the air duct 13 is too large during operation, resulting in a tiny gap between the bottom plate 11 and the cover plate 12, the air leakage channel formed by the gap is formed along the side walls of the recessed pattern 111 and the raised pattern 121, and the shape is also tortuous. The air in the air duct 13 cannot flow out smoothly from the air leakage channel, thereby reducing air escape and maintaining a good sealing effect of the base assembly 10.

[0042] See also Figure 4 and Figure 5 As another implementation of this embodiment, a water collecting groove 112 is formed on the bottom plate 11, and the water collecting groove 112 overlaps with the projection of the evaporator 20 of the clothes dryer on the bottom plate 11; the base assembly 10 also includes a support plate 15, which is arranged on the bottom plate 11, located at the opening of the water collecting groove 112, and is used to support the evaporator 20 of the clothes dryer; a plurality of water holes 151 are formed on the support plate 15. The support plate 15 can be a plastic plate obtained by injection molding, and the injection-molded plastic plate has good rigidity, can support the evaporator 20 without deformation, and stably supports it.

[0043] During operation, the humid air in the inner cavity of the dryer is pushed into the air duct 13 by the fan 80, and first passes through the surface of the evaporator 20. The temperature of the surface of the evaporator 20 is low, so the air can be cooled, and the moisture in the air is liquefied, which will drip downward under the influence of gravity. If the moisture is not collected in time, it will flow along the air duct 13 to the surface of the condenser 30, and even flow out of the air duct 13 and return to the inner cavity of the dryer, affecting the drying efficiency. Therefore, a water collection groove 112 is set at the projection position of the evaporator 20 for collecting water droplets in time.

[0044] In addition, the air duct 13 can be set to a straight line, and the evaporator 20 and the condenser 30 are set on the same straight line. After the air in the air duct 13 is dried, it can quickly flow to the surface of the condenser 30 to heat up, thereby accelerating the air circulation speed and improving the drying efficiency; the water collecting groove 112 is set below the evaporator 20, and a support plate 15 is set to support the evaporator 20, separating the evaporator 20 from the water collecting groove 112, so that the water on the surface of the evaporator 20 drips into the water collecting groove 112 through the water hole 151 and is discharged in time, instead of flowing to the condenser 30 or returning to the inner cavity of the dryer, thereby maintaining the normal operation of the heat pump system, maintaining a dry environment in the inner cavity of the dryer, and improving the working efficiency of the dryer.

[0045] See also Figure 6 As another implementation of this embodiment, it is disclosed that a plurality of retaining walls 152 are provided on one side of the support plate 15 facing the bottom plate 11, and the retaining wall 152 is located between two adjacent water holes 151; first, by forming a plurality of water diversion channels 153 in the water collecting groove 112, water dripping from different areas of the evaporator 20 flows out from different channels, and each water diversion channel 153 has a different position and a different total length, so the time for the water collected in different water diversion channels 153 to flow to the water outlet end of the water collecting groove 112 is different. Through this time difference, the gathering of water at the water outlet of the water collecting groove 112 can be reduced, so that the water in the water collecting groove 112 can be discharged in an orderly manner, avoiding filling in a local position and reducing the water outlet speed. It can also prevent the local water level from being too high, causing the water in the water collecting groove 112 to flow back from the water hole 151 to the inside of the air duct 13.

[0046] Second, a retaining wall 152 is provided to extend onto the bottom plate 11, dividing the water collecting groove 112 into a plurality of water diversion channels 153. The retaining wall 152 also has a certain supporting function, so that the overall structural strength of the support plate 15 is greater, and it is not easy to break when supporting the evaporator 20, and the support is stable.

[0047] In addition, in another implementation of the present embodiment, the retaining wall 152 is a zigzag retaining wall 152 or an arc-shaped retaining wall 152, and a tortuous water diversion channel 153 is formed between two adjacent retaining walls 152. Because water flows along the water diversion channel 153 formed by the retaining wall 152, the retaining wall 152 is set to be a zigzag or arc-shaped, so that the length of the water diversion channel 153 is increased, and the corner is increased. When the water flow hits the corner of the retaining wall 152, the flow rate is further slowed down. Overall, the formation of the tortuous water diversion channel 153 can further extend the time for the water flow to flow in the water collecting groove 112, so that the time difference of the water flow in each water diversion channel 153 is more obvious, and the effect of controlling the orderly outflow of the water flow is improved.

[0048] In addition, a baffle plate that forms an acute angle or a right angle with the water flow direction can be set in the water diversion channel 153. When water flows in the water diversion channel 153, it collides with the baffle plate and is forced to change the flow direction, thereby slowing down the overall flow speed and increasing the length of the water flow time; in this embodiment, it is preferred to set a baffle wall 152 in the water diversion channel 153 away from the water outlet end of the water collection groove 112, so that the water flow time in the water diversion channel 153 with a long flow time is longer, increasing the time difference with the water flow in the water diversion channel 153 with a short flow time, and increasing the effect of controlling the orderly drainage of the water collection groove 112.

[0049] like Figure 4 As shown, as another implementation of this embodiment, a water guide groove 113 is further formed on the bottom plate 11, one end of the water guide groove 113 is connected to the outlet of the water guide channel 153, and the other end is connected to the water tank 40 of the clothes dryer; the extension direction of the water guide groove 113 is the same as the air inlet direction of the air duct 13. The water guide groove 113 directly discharges the water at the outlet of the water guide channel 153 into the water tank 40 quickly, which can prevent water accumulation and avoid backflow; because the water guide channel 153 is connected to the air duct 13 through the water hole 151, the air at the air inlet will inevitably flow into the water guide channel 153 during air circulation, and then flow into the water guide groove 113, which just pushes the water in the water guide groove 113 to flow faster along the extension direction of the water guide groove 113 toward the water tank 40, that is, it can achieve the effect of accelerating drainage.

[0050] Specifically, as another implementation of this embodiment, the bottom surface of the water collecting groove 112, the bottom surface of the water guiding groove 113 and the inner surface of the water tank 40 of the clothes dryer are all coated with a waterproof layer. The waterproof layer prevents water from penetrating into these components, prevents rotting or breeding of bacteria, and maintains a dry and clean environment in the clothes dryer.

[0051] Specifically, as another implementation of this embodiment, a sealing strip is disclosed at the connection between the water guide groove 113 and the water collecting groove 112. The sealing strip forms a sealed connection between the water guide groove 113 and the water collecting groove 112, thereby avoiding the problem of water leakage caused by a gap formed by the physical connection between the water guide groove 113 and the water collecting groove 112. It should be noted that the sealing strip in this embodiment can be a foam sealing strip, a sponge sealing strip, etc.

[0052] See also Figure 7As another implementation of this embodiment, a water guide cover plate 114 is further provided on the bottom plate 11, which is used to cover the water guide groove 113; a water storage chamber 115 is formed on the water guide cover plate 114, and the water storage chamber 115 is provided on the side of the water guide groove 113. By providing a connection port 1131 on the side wall of the water guide groove 113, the water storage chamber 115 is connected with the inside of the water guide groove 113. Due to the limitation of the overall volume of the dryer, the diameter of the water guide groove 113 is also limited. The water storage chamber 115 is provided so that when the water flow in the water guide groove 113 is too large, part of the water can enter the water storage chamber 115 through the connection port 1131, and the excess water is temporarily stored in the water storage chamber 115, so as to share the pressure of the water outlet end of the water guide groove 113, prevent the formation of excessive water pressure in the water guide groove 113, and avoid water backflow.

[0053] Specifically, as another implementation of this embodiment, the water guide cover plate 114 is disclosed to be sealed and connected with the water guide groove 113. The water guide cover plate 114 is covered on the water guide groove 113 to form a sealed water guide channel, which can prevent water from overflowing the water guide groove 113 and completely guide the water flow into the water tank 40 for centralized collection. The water guide cover plate 114 can be a plastic cover plate obtained by injection molding. The injection molded plastic plate has good rigidity and can be tightly matched with the water guide groove 113 formed by the foamed plastic part, and the sealing performance of the assembly is good.

[0054] Specifically, as another implementation of this embodiment, a guide plate is provided on the side wall of the water guide groove 113 away from the connection port 1131, and the guide plate is used to guide water to the connection port 1131. Because the connection port 1131 is provided on the side wall of the water guide groove 113, the flow direction of the water flow in the natural flow state is parallel to the connection port 1131, and the amount of water flowing into the water storage chamber 115 is small, so that the function of the water storage chamber 115 cannot be fully utilized; therefore, by guiding the direction of the water flow of the plate cover 12, more water can enter the water storage chamber 115, and the function of the water storage chamber 115 can be fully utilized.

[0055] like Figure 7As shown, as another implementation of this embodiment, a plurality of inner baffles 1151 are provided in the water storage chamber 115, and the shape of the inner baffles 1151 is a broken line or an arc, and is used to form a tortuous labyrinth waterway 1152 in the water storage chamber 115. The water in the water storage chamber 115 is only temporarily stored, and will eventually flow back to the water guide groove 113 for discharge. However, when the water flow in the water guide groove 113 is large, the water entering the water storage chamber 115 cannot immediately flow back to the water guide groove 113, otherwise the water pressure in the water guide groove 113 will further increase, affecting the drainage efficiency. Therefore, the inner baffles 1151 are provided in the water storage chamber 115, and the tortuous labyrinth waterway 1152 is formed by the inner baffles 1151 and the side wall of the water storage chamber 115, so that After the water flows into the water storage chamber 115, it is divided into multiple streams and flows in the labyrinth water channel 1152. When the water pressure at the connection port 1131 decreases, indicating that the water flow in the water guide groove 113 decreases, the water in the water storage chamber 115 can be discharged. The tortuous labyrinth water channel 1152 makes the flow speeds of the multiple streams different, and the return distances are different, so that a return water flow with a smaller overall flow rate is formed at the connection port 1131, and the remaining water is discharged in an orderly manner, reducing the drainage pressure of the water guide groove 113.

[0056] like Figure 1 As shown, as another embodiment of the present application, a clothes dryer is disclosed, which includes any of the above-mentioned base components 10. The above-mentioned base component 10 is arranged on the sheet metal bracket 50 of the clothes dryer, so that the heat pump system can be stably operated and the drying function can be realized efficiently and stably.

[0057] Specifically, Figure 2 As shown, another implementation of the present embodiment discloses that the dryer also includes a sheet metal bracket 50 supporting the base assembly 10, and a motor 60, a compressor 70, a fan 80 and other structures arranged on the sheet metal bracket 50. The motor 60 supplies power to the fan 80 and the compressor 70, and the compressor 70 connects the evaporator 20 and the condenser 30 for heat exchange. The fan 80 can be arranged at the air inlet of the air duct 13, or at the air outlet of the air duct 13, or in the air duct 13, near the air outlet, to promote air circulation through the rotation of the fan blades.

[0058] In summary, the present application discloses a base assembly 10 for a clothes dryer, which includes a base plate 11, a cover plate 12 and a fixing member 14, wherein the cover plate 12 is arranged on the base plate 11; an air duct 13 with openings at both ends is formed between the cover plate 12 and the base plate 11; the evaporator 20 and the condenser 30 of the clothes dryer are sequentially arranged in the air duct 13 along the air inlet direction of the air duct 13; the fixing member 14 is assembled simultaneously with the base plate 11 and the cover plate 12, and is used to make the cover plate 12 and the base plate 11 have an interference fit. The base assembly 10 disclosed in the present application is formed by the cover plate 12 and the bottom plate 11 covering and cooperating to form an air duct 13. Both ends of the air duct 13 are connected to the inner cavity of the dryer. An evaporator 20 and a condenser 30 are arranged in the air duct 13, and a fan 80 is used to blow air into the air duct 13, so that the air in the inner cavity of the dryer forms a cycle; in order to resist the wind pressure in the air duct 13 during the air circulation process, a fixing member 14 is arranged to assemble the cover plate 12 and the bottom plate 11 at the same time, so that the cover plate 12 and the bottom plate 11 are interference-fitted, that is, the cover plate 12 and the bottom plate 11 are squeezed against each other, thereby reducing the gap at the contact position between the cover plate 12 and the bottom plate 11, increasing the overall air tightness of the air duct 13, and improving the sealing effect; during the circulation process, the heat of the air heated by the condenser 30 can be more efficiently transferred to the inner cavity of the dryer, thereby maintaining the good performance of the dryer. In addition, the fixing member 14 forms a stable connection between the cover plate 12 and the bottom plate 11, which is conducive to maintaining the stability of the dryer structure and long-term use.
