[0001] The invention belongs to the field of dishwashers, and in particular relates to a heat dissipation and moisture dissipation protection structure for a dishwasher motor and a dishwasher. Background Art

[0002] Common household dishwashers are generally equipped with a drying device, which generally includes an air duct, a fan and a heating device. The air duct is connected to the inner tank, and the fan and the heating device are located at the bottom of the dishwasher. The fan generates air flow and heats it through the heating device, so that the air flow has heat, which is then output to the inner tank and used to dry the dishes. In actual applications, during the washing process of the dishwasher, the hot air or steam in the inner tank enters the air duct, condenses into water droplets, and flows down the side wall of the air duct into the drying module, which can easily affect the drying module and even cause the motor in the drying module to fail, thereby creating risks.

[0003] The Chinese patent application number 202221802341.7 discloses a dishwasher and a drying device thereof, including an air duct and a fan arranged in the air duct, wherein the air duct is connected to the interior of the dishwasher cavity; the air duct is provided with a cut-off rib and a return pipe for preventing water from flowing to the fan, and the cut-off rib extends to the pipe mouth of the return pipe; the return pipe extends outward from the air duct, and the extended end of the return pipe is connected to the interior of the dishwasher cavity, and a dishwasher having the above-mentioned drying device is also provided. In order to solve the technical problem that the condensed water in the drying device of the dishwasher is easy to damage the fan. However, the fan of the public application is arranged in the air duct, and the arrangement of the guide pipe occupies a certain space, which increases the complexity of design and assembly.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0006] Another aspect of the present invention provides a dishwasher using the heat dissipation and moisture dissipation protection structure of the dishwasher motor.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A first aspect of the present invention provides a motor heat dissipation and moisture dissipation protection structure for a dishwasher. The dishwasher comprises an air duct and a drying module, and the drying module is connected to the air duct.

[0009] Furthermore, the air duct is provided with water guide ribs, and the water guide ribs are used to guide water along a set trajectory; the drying module is provided with a guide port, and the guide port is used to guide water out.

[0010] Furthermore, an air guide portion is provided at the connection between the air duct and the drying module, and the water guide ribs are provided at the air guide portion.

[0011] Furthermore, the air guide portion gradually decreases from the air inlet to the air outlet, and the water guide rib is arranged near the air outlet.

[0012] Furthermore, the water guide ribs are arranged on the upper wall and two side walls of the air outlet of the air guide part to form a 3 / 4 circle.

[0013] Advantageously, the water guiding ribs are arranged on the upper wall and the two side walls of the air guiding portion to form a 3 / 4 circle, which can effectively guide the water on the upper wall and the two side walls of the air guiding portion to the lower wall, facilitating the discharge of water.

[0014] Furthermore, the drying module comprises a heating module and a protective cover, the drying module is installed in the protective cover, there is a gap between the heating module and the protective cover, and a first guide port is provided on the protective cover.

[0015] Advantageously, there is a gap between the heating module and the protective cover, which can prevent the protective cover or the dishwasher from being damaged when the heating module is heated at a high temperature, and can also ensure that water does not contact the heating module.

[0016] Furthermore, the protective cover includes an air inlet end, an air outlet end and a bottom wall, and the first air guide port is arranged on the bottom wall close to the air inlet end.

[0017] Furthermore, the heat dissipation and moisture dissipation protection structure of the dishwasher motor also includes a mounting seat, which is a wedge-shaped structure, including an inclined plate and a semi-enclosed structure, and the inclined plate and the semi-enclosed structure are used to fix the drying module.

[0018] Furthermore, the air inlet end of the protective cover is located at a lower part of the inclined plate of the mounting base, and a second air guide port is provided on the inclined plate at a position opposite to the first air guide port.

[0019] Furthermore, the area of ​​the second guide port is greater than or equal to the area of ​​the first guide port.

[0020] Advantageously, the area of ​​the second guide port is larger than that of the first guide port, which can ensure that the water flowing through the first guide port can be discharged from the second guide port without any water residue; at the same time, it prevents the water from forming a water film at the first guide port and failing to drip, and flowing into between the protective cover and the mounting base, causing water accumulation.

[0021] Another aspect of the present invention provides a dishwasher, which uses the above-mentioned dishwasher motor heat dissipation and moisture dissipation protection structure.

[0022] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: water-guiding ribs are arranged on the air duct, which can effectively prevent condensed water in the air duct from entering the heating module; guide ports are arranged on the drying module and the mounting seat, which can effectively discharge the condensed water in the air duct through the guide ports; and it is directly arranged on the air duct, the drying module and the mounting seat, which is simple to operate, does not take up extra space, saves space, and improves user acceptance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 3 As shown, in a first aspect of the present invention, a heat dissipation and moisture dissipation protection structure of a dishwasher is provided, wherein the dishwasher comprises an air duct, a drying module 2 and a mounting seat 3.

[0034] Furthermore, the dishwasher further comprises an inner tank and a base, a mounting chamber is formed between the inner tank and the base, and the mounting seat 3 is mounted in the mounting chamber.

[0035] Specifically, in the installation chamber formed by the inner tank and the base of the dishwasher, the mounting seat 3 is horizontally installed in the chamber, and the drying module 2 is installed on the mounting seat 3 to provide hot air at an angle upward; one end of the drying module 2 is connected to the air duct, and the hot air generated by the drying module 2 is input into the inner tank of the dishwasher after passing through the air duct to dry the tableware in the inner tank.

[0036] Furthermore, water guide ribs 13 are provided on the air duct to prevent water from flowing toward the drying module 2; and a diversion port is provided on the drying module 2 to divert the water blocked and diverted by the water guide ribs 13 in the air duct to avoid damage to the drying module 2.

[0037] Furthermore, an air guide portion 1 is provided at the connection between the air duct and the drying module 2, and the diameter of the air guide portion 1 gradually decreases from the air inlet 12 to the air outlet 11, and the water guide ribs 13 are obliquely arranged near the air outlet 11 of the air guide portion 1, and are arranged on the upper wall and both side walls to form a 3 / 4 circle.

[0038] Specifically, the air guide portion 1 is a pipe with two ends of different diameters, the end with a larger diameter is the air inlet 12, and the end with a smaller diameter is the air outlet 11. The radial cross section of the air guide portion 1 is a rectangle with four rounded corners.

[0039] Specifically, the radial cross-section of the air guide portion 1 is a smaller rectangle wrapped in a larger rectangle, the air inlet 12 corresponds to a rectangle with a larger radial cross-section, and the four corners are arc-shaped corresponding to the air outlet end of the drying module 2, and the air outlet 11 corresponds to a rectangle with a smaller radial cross-section, and its shape corresponds to the radial cross-section of the air duct, and the rectangular radial cross-section of the air outlet 11 is not centered on the rectangular radial cross-section of the air inlet 12, but is biased toward the position of the upper wall of the air guide portion 1.

[0040] Specifically, the air duct extends up and down, the air guide part 1 is arranged at the bottom of the air duct, and the inclination angle of the upper wall of the air guide part 1 contracting inward from the air inlet 12 to the air outlet 11 is smaller than the inclination angle of the lower wall of the air guide part 1 contracting inward from the air inlet 12 to the air outlet 11.

[0041] Specifically, the upper wall of the air guide portion 1 can be arranged parallel to the upper wall of the drying module 2 in the direction from the air inlet 12 to the air outlet 11, and the lower wall of the air guide portion 1 contracts inwardly from the air inlet 12 to the air outlet 11. The upper wall of the air guide portion 1 is arranged parallel to the upper wall of the drying module 2, so that the high-speed hot air blown from the upper part of the drying module 2 can be blown into the air duct more smoothly, thereby better weakening the impact of the high-speed hot air on various components, reducing wind resistance, and reducing noise.

[0042] Specifically, the two side walls of the air guide portion 1 shrink inwardly from the air inlet 12 to the air outlet 11 at the same inclination angle.

[0043] Specifically, the edge of the peripheral wall of the air guide portion 1 is an arc surface, which is arranged as an arc surface with a gradually decreasing width from the air inlet 12 to the air outlet 11. The two sides of the arc surface of the upper half are connected to the upper wall and side walls of the air guide portion 1, and the two sides of the arc surface of the lower half are connected to the lower wall and side walls of the air guide portion 1. On the one hand, the arc surface is arranged to correspond to the drying module 2, thereby improving the overall aesthetics. On the other hand, the arc structure can also effectively reduce the impact of hot air, reduce the overall vibration and thus reduce noise.

[0044] Specifically, the water guiding ribs 13 are arranged to bend the upper wall and the two side walls of the air duct at the position of the air guiding part 1 near the air outlet 11 inwardly, thereby forming a resistance structure; the air outlet 11 is located above the air inlet 12, and the diameter is smaller than the air inlet 12, and the water guiding ribs 13 are arranged near the air outlet 11 to form a 3 / 4 circle. On the one hand, water flows from the upper wall and the two side walls to the lower wall through the guiding effect of the water guiding ribs 13, and then flows downward along the lower wall; on the other hand, it can prevent a large amount of water from entering the drying module 2 from the air guiding part 1, causing damage or short circuit of the drying module 2.

[0045] Furthermore, the drying module 2 includes a heating module 22 and a protective cover 21. The heating module 22 is installed in the protective cover 21 and there is a gap between the heating module 22 and the protective cover 21. A first air guide port 2111 is provided on the protective cover 21, and the first air guide port 2111 is provided on the bottom wall 211 of the protective cover 21 near the air inlet end.

[0046] Specifically, the bottom wall 211 of the protective cover 21 is configured to be a trough body extending a certain length and having an open upper side. A fan, a fixing part and a heating module 22 are sequentially arranged inside the bottom wall 211 of the protective cover 21. The heating module 22 is provided with an outer shell, and the heating component is arranged inside the outer shell. The outer shell is installed in the protective cover 21 through the fixing part. There is a certain gap between the inner wall of the protective cover 21 and the outer surface of the outer shell. On the one hand, the setting of the protective cover 21 can play a heat-insulating role and reduce the heat loss of the heating module 22; on the other hand, the setting of the fixing part can prevent the outer shell of the heating module 22 from directly contacting the protective cover 21, so as to damage the protective cover 21 or the inner tank of the dishwasher.

[0047] Specifically, the protective cover 21 needs to install the air supply device and the heating module 22 inside to form a whole. The protective cover 21 has ventilation holes at the position where the air supply device and the heating module 22 are connected, and there is also a corresponding ventilation cavity on the fixing part, so that the wind blown from the fan can be blown into the heating module 22 through the ventilation holes and the ventilation cavity on the fixing part.

[0048] Furthermore, the air outlet end of the protective cover 21 is inserted into the air inlet 12 of the air guide portion 1 or is sleeved outside the air inlet 12 of the air guide portion 1 .

[0049] Specifically, the protective cover 21 is sleeved on the outside of the air inlet 12, and the protective cover 21 is connected to the air duct through a snap-fit ​​structure, which includes: a protrusion, which is arranged on one of the protective cover 21 and the air inlet 12; and a bayonet, which is arranged on the other of the protective cover 21 and the air inlet 12 and cooperates with the protrusion of the protective cover 21.

[0050] Preferably, the protective cover 21 is a rectangular parallelepiped, and the four edges of the rectangular parallelepiped parallel to the axis are provided with arc chamfers. The protective cover 21 snap-in is arranged on the side of the protective cover 21 close to the air duct, and multiple protective cover 21 snap-ins are evenly arranged along the peripheral wall of the protective cover 21. Multiple protrusions are arranged on the outer surface of the air inlet 12, and are arranged one by one corresponding to each protrusion.

[0051] In some possible embodiments, one end of the protective cover 21 with the bayonet of the protective cover 21 is sleeved outside the air duct, and the inner surface of the protective cover 21 fits with the outer surface of the air inlet 12 of the air duct. The protrusions and the bayonet of the protective cover 21 cooperate with each other to connect the heating module 22 to the air duct. On the one hand, the detachable connection between the heating module 22 and the air duct is realized. On the other hand, the protective cover 21 is made of plastic and has a good deformation amount, which is more labor-saving during installation.

[0052] In other possible embodiments, the protective cover 21 is inserted into the air duct, and the protective cover 21 and the air duct are connected by a snap-fit ​​structure, which includes: a protrusion of the protective cover 21, which is arranged on one of the protective cover 21 and the air inlet 12; and an air supply duct snap-fit, which is arranged on the other of the protective cover 21 and the air inlet 12 and cooperates with the protrusion of the protective cover 21.

[0053] Specifically, the hot air flows from the protective cover 21 toward the air duct, and the protective cover 21 is inserted into the air duct to avoid leakage of the hot air.

[0054] Preferably, the protective cover 21 is a rectangular parallelepiped with four rounded corners. The protrusion of the protective cover 21 is arranged on the side of the protective cover 21 close to the air duct. Multiple protrusions of the protective cover 21 are evenly arranged along the peripheral wall of the protective cover 21, and multiple air supply duct snap-ons are arranged one by one corresponding to each protrusion of the protective cover 21.

[0055] Specifically, the end of the protective cover 21 close to the fixing part is the air inlet end of the heating module 22, and the end connected to the air duct is the air outlet end. A guide port is provided on the bottom wall 211 close to the air inlet end, so that water flowing down the lower wall of the air duct guide part 1 can flow through the gap between the protective cover 21 and the heating module 22 to the first guide port 2111 and flow out from the first guide port 2111.

[0056] Preferably, the bottom wall 211 of the protection cover 21 provided with the first guide port 2111 is integrally formed by plastic compression molding, which can ensure the stability of the overall structure.

[0057] Furthermore, the heat dissipation and moisture dissipation protection structure of the dishwasher motor also includes a mounting seat 3, which is a wedge-shaped structure, including an inclined plate 31 and a semi-enclosed structure, and the inclined plate 31 and the semi-enclosed structure are used to fix the protective cover 21.

[0058] Furthermore, the air inlet end of the protective cover 21 is located at the lower part of the inclined plate 31 of the mounting seat 3 , and a second air guide port 311 is provided on the inclined plate 31 at a position opposite to the first air guide port 2111 .

[0059] Specifically, the wedge-shaped support body is provided with an inclined plate 31 and a horizontal plate. The inclined plate 31 is located above the horizontal plate. The horizontal plate is connected to the lowest end of the inclined plate 31, and the connection between the two is at a certain distance from the edge of the horizontal plate.

[0060] Specifically, the semi-enclosed structure is located on the inclined plate 31 of the wedge-shaped support body, and includes two opposite side walls and an end wall connecting one end of the two side walls, and the other end opposite to the end wall is open, and a notch is provided on the end wall connecting the two side walls. A card slot is provided on the two opposite side walls of the semi-enclosed structure for connecting with the drying module 2.

[0061] Specifically, the second guide port 311 is disposed at a lower portion of the inclined plate 31 of the mounting seat 3 , and can effectively guide the water flowing out of the protective cover 21 .

[0062] Specifically, the protective cover 21 is installed in the semi-enclosed structure of the mounting seat 3 and fixed by claws and slots. The position of the first guide port 2111 coincides with the position of the second guide port 311, and the area of ​​the second guide port 311 is larger than the area of ​​the first guide port 2111, so that water can flow through the first guide port 2111 to the second guide port 311 and then be discharged.

[0063] Preferably, the mounting seat 3 provided with the second air guide port 311 is integrally formed by plastic compression molding, which can ensure the stability of the overall structure.

[0064] A second aspect of the present invention provides a dishwasher using the above-mentioned dishwasher motor heat dissipation and moisture dissipation protection structure.

[0065] The mounting seat 3 is installed in a chamber formed by the inner tank and the base of the dishwasher, and the drying device is installed on the base to provide hot air obliquely upward, and then the hot air enters the inner tank of the dishwasher through the air duct to dry the tableware in the inner tank of the dishwasher.

[0066] In this embodiment, the drying device is located below the dishwasher, at a relatively low point. During the washing or drying process of the dishwasher, water vapor or water vapor in the inner tank may enter the air duct through the air duct outlet, condense into water droplets on the side walls of the air duct, and then flow downward along the side walls of the air duct.

[0067] When water flows to the air guide part 1 of the air duct, it is blocked by the water guide ribs 13 on the upper wall and the two side walls of the air duct, and flows along the water guide ribs 13 to the lower wall, and then flows along the lower wall to the gap between the protective cover 21 and the heating module 22, and flows downward along the inclined angle to the first guide port 2111, and after flowing through the first guide port 2111, it reaches the second guide port 311 and flows out from the second guide port 311, so as not to flow to the heating module 22 or the air supply device, thereby protecting the air supply device and the heating module 22.
