Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a zeolite heating and regeneration structure for dishwashers. Background Art

[0002] As a common appliance in modern kitchens, dishwashers play an important role in the drying process of dishes after washing. In existing dishwasher technology, a common drying method is to use a zeolite drying module. Its working principle is that when the dishes in the dishwasher tank are washed and enter the drying stage, the hot and humid gas in the tank is sucked into the air duct through the exhaust fan. The hot and humid gas flows through the zeolite drying module in the air duct. The zeolite absorbs moisture by its own characteristics, and the dried air is then sent back to the dishwasher tank, thereby drying the dishes.

[0003] When the zeolite needs to be regenerated, the heating element is usually used to generate heat and cooperate with the exhaust fan to generate hot air. The specific operation is to run the exhaust fan to introduce air into the air duct, and the heating element heats the air to form hot air. The hot air blows to the zeolite drying module, so that the zeolite is regenerated at high temperature and releases the moisture absorbed before. The moisture is also blown back to the dishwasher tank. In addition, in order to improve the overall working efficiency of the dishwasher, the time for zeolite regeneration and restoration is usually set during the washing process of the dishwasher.

[0004] However, this prior art solution has obvious disadvantages. In the process of zeolite drying hot and humid gas, since the heating element is located in the air duct, the hot and humid gas will inevitably pass through the heating element when entering the air duct and flowing to the zeolite drying module. At this time, the heating element is not working, and the water vapor in the hot and humid gas will adhere to and remain on the surface of the heating element. When the subsequent zeolite regeneration requires the heating element to work, these residual water vapors will cause many problems. On the one hand, the presence of water vapor increases the thermal resistance of the heating element during heating, so that the heating element needs to consume more electrical energy to achieve the expected heating effect, which undoubtedly increases the energy consumption of the dishwasher. On the other hand, a humid environment will expose the heating element to the risk of short circuit. Once a short circuit occurs, it will not only damage the dishwasher, but may even cause safety accidents, such as fires, etc., which will bring great safety hazards to users.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0006] In view of the above-mentioned deficiencies of the prior art, an object of the present invention is to provide a zeolite heating regeneration structure for a dishwasher, aiming to avoid unnecessary contact between hot and humid gas and the heater, thereby reducing the possibility of water vapor condensing and remaining on the heater surface.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A zeolite heating and regeneration structure for a dishwasher comprises a main exhaust channel and a zeolite drying module arranged in the main exhaust channel, wherein the input end and the output end of the main exhaust channel are both connected to the inner tank of the dishwasher, the main exhaust channel is provided with a bypass channel upstream of the zeolite drying module, the input end of the bypass channel is connected to a hair dryer, a heater is arranged in the bypass channel, and a swingable baffle is arranged at the output end of the bypass channel, the baffle is used to isolate the bypass channel from the main exhaust channel when the zeolite absorbs moisture and dries, the hair dryer cooperates with the heater to generate hot air, and the hot air blows open the baffle and flows to the zeolite drying module.

[0009] As a further improvement of the above technical solution, a pivot is provided in the bypass channel, and a connecting tube rotatably connected to the pivot is provided on the baffle. The baffle is rectangular and the length of the baffle is greater than the width of the main exhaust channel and the bypass channel.

[0010] As a further improvement of the above technical solution, the adapter tube is arranged at one end of the baffle and adjacent to the side wall of the bypass channel. The baffle is provided with a counterweight block at the end away from the adapter tube, and the baffle is pressed against the junction of the bypass channel and the main exhaust channel.

[0011] As a further improvement of the above technical solution, the counterweight block is an iron block and is arranged on the end face of the baffle facing the main exhaust channel, and a thermally sensitive soft magnetic block that can undergo magnetic attraction with the counterweight block is provided at the output end of the bypass channel.

[0012] As a further improvement of the above technical solution, the outer surface of the inner tank of the dishwasher is provided with a raised surface corresponding to the main exhaust channel and the bypass channel, and the raised surface is connected to the main exhaust channel through a thermally conductive adhesive to achieve heat transfer.

[0013] As a further improvement of the above technical solution, the heater is one of a PTC ceramic chip heater, a thick film heater and a graphene heater.

[0014] As a further improvement of the above technical solution, a wiring groove is provided in the bypass channel for routing the heater outward.

[0015] As a further improvement of the above technical solution, the connection between the bypass channel and the main exhaust channel is an arc transition setting.

[0016] As a further improvement of the above technical solution, a portion of the main exhaust channel is arranged on the side of the inner tank of the dishwasher and extends vertically, and the bypass channel is arranged on the side of the inner tank of the dishwasher.

[0017] Beneficial effects of the present invention: The zeolite heating and regeneration structure provided by the present invention not only arranges the heater by setting a bypass channel, but also cleverly uses a baffle to reliably separate the bypass channel from the main exhaust channel when the zeolite absorbs moisture and dries, ensuring that the hot and humid gas can only flow through the zeolite drying module according to the predetermined path for drying operations, avoiding unnecessary contact between the hot and humid gas and the heater, thereby reducing the possibility of water vapor condensing and remaining on the surface of the heater. This not only reduces the additional energy consumption caused by the increase in thermal resistance due to residual water vapor, but also eliminates safety hazards such as heater short circuit caused by a humid environment, achieving synergistic improvements in the two key aspects of energy saving and safety, and providing users with a more economical and safe use experience. When the zeolite is heated and regenerated, the baffle can be automatically blown open by hot air, without the need for additional complex mechanical drive devices or electronic control systems to control its opening and closing movements. This design simplifies the structure of the entire zeolite heating and regeneration structure, reduces the number of components, and thus reduces manufacturing and installation costs, making the dishwasher more economical and market competitive while ensuring functionality.

[0022] The present invention provides a zeolite heating and regeneration structure for a dishwasher. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0023] See also Figures 1 to 3The present invention provides a zeolite heating and regeneration structure for a dishwasher, comprising an exhaust main channel 1 and a zeolite drying module 7 arranged in the exhaust main channel 1, the input end and the output end of the exhaust main channel 1 are both connected to the inner tank 8 of the dishwasher, the exhaust main channel 1 is provided with a bypass channel 2 upstream of the zeolite drying module 7, the input end of the bypass channel 2 is connected to a hair dryer 4, a heater 3 is arranged in the bypass channel 2, and a swingable baffle 5 is arranged at the output end of the bypass channel 2, the baffle 5 is used to isolate the bypass channel 2 from being connected with the exhaust main channel 1 when the zeolite absorbs moisture and dries, the hair dryer 4 cooperates with the heater 3 to generate hot air, and the hot air blows open the baffle 5 and flows to the zeolite drying module 7.

[0024] See Figure 1 As shown, when the dishes in the inner tank 8 of the dishwasher are washed and enter the drying stage, the exhaust fan 11 draws the hot and humid gas in the inner tank 8 into the main exhaust channel 1. At this time, due to the partition effect of the baffle 5, the bypass channel 2 is not connected to the main exhaust channel 1. The hot and humid gas flows directly to the zeolite drying module 7 in the main exhaust channel 1. The zeolite absorbs moisture by its own characteristics, and the dried air is then sent back to the inner tank 8 of the dishwasher to dry the dishes.

[0025] See Figure 2 As shown, when the zeolite needs to be regenerated, the blower 4 starts to work, introducing external air into the bypass channel 2, and the heater 3 heats the air in the bypass channel 2 to form hot air. The hot air blows toward the swingable baffle 5. Since the baffle 5 is thin, the baffle 5 is pushed away from the bypass channel 2 by the force of the hot air, so that the bypass channel 2 is connected with the main exhaust channel 1, and the hot air can flow smoothly to the zeolite drying module 7. The hot air regenerates the zeolite at high temperature and releases the moisture absorbed before, and the moisture is blown back to the inner tank 8 of the dishwasher.

[0026] It is understandable that when the generation of hot air is canceled, the baffle 5 will close the bypass channel 2 again under the action of its own gravity.

[0027] Compared with the prior art, the zeolite heating and regeneration structure provided by the present invention not only arranges the heater 3 by setting the bypass channel 2, but also cleverly uses the baffle 5 to reliably separate the bypass channel 2 and the exhaust main channel 1 when the zeolite absorbs moisture and dries, ensuring that the hot and humid gas can only flow through the zeolite drying module 7 according to the predetermined path for drying operation, avoiding unnecessary contact between the hot and humid gas and the heater 3, thereby reducing the possibility of condensation and residue of water vapor on the surface of the heater 3. This not only reduces the additional energy consumption caused by the increase in thermal resistance due to residual water vapor, but also eliminates the safety hazards such as short circuit of the heater 3 caused by the humid environment, and achieves synergistic improvement in the two key aspects of energy saving and safety, providing users with a more economical and safe use experience. When the zeolite is heated and regenerated, the baffle 5 can be automatically blown open by the hot air, without the need for an additional complex mechanical drive device or electronic control system to control its opening and closing action. This design simplifies the structure of the entire zeolite heating and regeneration structure, reduces the number of parts, thereby reducing the manufacturing and installation costs, and makes the dishwasher more economical and market competitive while ensuring the function.

[0028] Specifically, a pivot 21 is provided in the bypass channel 2, and a transfer tube 51 is provided on the baffle 5, which is rotatably connected to the pivot 21. The rotatable connection between the pivot 21 and the transfer tube 51 provides a stable rotation fulcrum for the baffle 5, so that the baffle 5 can swing smoothly during multiple opening and closing actions. The baffle 5 can also achieve flexible opening and closing actions in a limited space, and there is no need to reserve a large space to accommodate complex driving devices or moving parts with a large stroke. This compact structural design is conducive to optimizing the internal space layout of the dishwasher, so that the dishwasher can better integrate various functional components within a limited volume, improve the space utilization of the equipment, and provide possibilities for the miniaturization design of the dishwasher or the further expansion of internal functional modules.

[0029] Furthermore, the baffle 5 is rectangular and the length of the baffle 5 is greater than the width of the main exhaust channel 1 and the bypass channel 2. Through such a setting, in addition to the baffle 5 being able to effectively seal the entire bypass channel 2 under natural hanging, more importantly, after the baffle 5 is blown open, one end of the baffle 5 will abut against the inner wall of the main exhaust channel 1, thereby blocking the main exhaust channel 1 and guiding all the hot air to flow to the zeolite drying module 7 without being diverted to the exhaust fan 11, so that the heat generated during the regeneration process can be concentrated on the zeolite drying module 7. This maximizes the utilization of heat and enables the zeolite to regenerate more quickly and efficiently. Therefore, this design optimizes the heat distribution during the regeneration process, improves the working efficiency of the drying and regeneration cycle of the entire dishwasher, shortens the single cycle time, and saves time and energy costs for users.

[0030] In order to ensure that the baffle 5 can be reset after being blown open, the adapter tube 51 is arranged at one end of the baffle 5 and adjacent to the side wall of the bypass channel 2. The baffle 5 is provided with a counterweight 61 at the end away from the adapter tube 51, thereby forming a stable lever arm structure, and the baffle 5 is pressed against the junction of the bypass channel 2 and the main exhaust channel 1. After the hot air stops, the counterweight 61 uses the torque generated by its own gravity to effectively cause the baffle 5 to rotate and reset around the adapter tube 51. This design effectively prevents the situation where the baffle 5 cannot be normally reset to close the bypass channel 2 due to residual airflow, slight mechanical jamming or other unexpected factors, and ensures that after each zeolite regeneration is completed, the bypass channel 2 can be promptly and reliably restored to the closed state, maintaining the stable operation of the normal drying process of the dishwasher, and avoiding the hot and humid gas caused by the abnormal opening of the bypass channel 2 entering the bypass channel 2 and affecting the heater 3.

[0031] In order to make the baffle 5 obtain the best effect of isolating the hot and humid gas as much as possible, the counterweight block 61 is an iron block and is arranged on the end face of the baffle 5 facing the exhaust main channel 1, and the output end of the bypass channel 2 is provided with a thermosensitive soft magnetic block 62 that can have a magnetic attraction with the counterweight block 61. Under normal temperature environment, when the dishwasher is in the non-zeolite regeneration stage, the thermosensitive soft magnetic block 62 at the output end of the bypass channel 2 is magnetic, and it has a magnetic attraction with the counterweight block 61 (iron block) arranged on the end face of the baffle 5 facing the exhaust main channel 1. This magnetic attraction force makes the baffle 5 tightly pressed against the junction of the bypass channel 2 and the exhaust main channel 1, so as to reliably close the bypass channel 2. The exhaust main channel 1 normally guides the hot and humid gas in the inner tank 8 to the zeolite drying module 7 for drying operation, so as to prevent the hot and humid gas from entering the bypass channel 2. Under normal temperature conditions, the magnetic attraction of the thermosensitive soft magnetic block 62 and the counterweight block 61 provides additional closing force for the baffle 5. This force can effectively compensate for the insufficient sealing caused by factors such as the unstable movement of the baffle 5 caused by the gap in the mechanical structure or the hot and humid air flow, so that the junction between the baffle 5 and the bypass channel 2 and the main exhaust channel 1 can fit more closely.

[0032] When the zeolite needs to be regenerated, the blower 4 and the heater 3 in the bypass channel 2 work to generate hot air. With the action of the hot air, the temperature of the thermosensitive soft magnetic block 62 rises and gradually loses its magnetism, and the magnetic attraction between it and the counterweight block 61 weakens until it disappears. At this time, the hot air can smoothly push the baffle 5 to overcome the small resistance and rotate around the adapter tube 51, thereby opening the channel between the bypass channel 2 and the main exhaust channel 1, so that the hot air flows to the zeolite drying module 7 to realize the regeneration process.

[0033] The demagnetization characteristics of the thermosensitive soft magnetic block 62 are closely related to the hot air temperature. Only when the hot air reaches the Curie temperature of the thermosensitive soft magnetic block 62, the thermosensitive soft magnetic block 62 will be demagnetized, thereby allowing the baffle 5 to open under the hot air pressure. This characteristic realizes the precise control of the opening timing of the baffle 5, ensuring that the baffle 5 will be opened in time when the hot air conditions required for zeolite regeneration are met. At the same time, since the demagnetization process of the thermosensitive soft magnetic block 62 is a gradual process, it can also play a certain role in limiting and buffering the opening range of the baffle 5. In the early stage of hot air, the magnetic attraction gradually weakens, and the baffle 5 opens slowly, avoiding the baffle 5 from opening too much or causing damage to the mechanical structure due to a sudden strong impact, so that the baffle 5 can be opened in a relatively stable manner, which is conducive to the stable control of the airflow and the safe operation of the equipment during the entire regeneration process.

[0034] In order to reduce the energy consumption of zeolite heating and regeneration, the outer surface of the inner tank 8 of the dishwasher is provided with a convex surface corresponding to the exhaust main channel 1 and the bypass channel 2, and the convex surface is connected to the exhaust main channel 1 through a thermally conductive adhesive to achieve heat transfer. During the hot rinsing process of the dishwasher, the temperature of the inner tank 8 rises, and the convex surface on its outer surface absorbs heat by being in close contact with the inner tank 8. Since the convex surface is connected to the exhaust main channel 1 through a thermally conductive adhesive, heat can be efficiently transferred from the convex surface to the inside of the exhaust main channel 1. In the zeolite regeneration stage, when the heater 3 in the bypass channel 2 works to generate hot air, the heat from the hot rinsing of the inner tank 8 is also conducted to the zeolite drying module 7 through the exhaust main channel 1. In this way, even if the heater 3 does not need to output too high power, the zeolite drying module 7 can reach the temperature conditions required for regeneration with the assistance of the heat of the hot rinsing, thereby realizing the regeneration process of the zeolite. With the help of the waste heat of the inner tank 8, this design can generally reach 55°C-60°C, which greatly reduces the workload of the heater 3. This means that during the entire operating cycle of the dishwasher, electricity consumption is significantly reduced, which helps users save electricity bills. It is also in line with the development trend of energy conservation in modern home appliances, improves the energy utilization efficiency of the dishwasher, and reduces energy pressure on the environment.

[0035] Preferably, the heater 3 is one of a PTC ceramic chip heater, a thick film heater and a graphene heater. The PTC ceramic chip heater has a self-regulating temperature function, can quickly heat up to the set temperature and stabilize within a certain range, ensuring a continuous and stable heat supply during the zeolite regeneration process and improving the heating efficiency. The heating resistor slurry of the thick film heater can generate heat evenly, so that the air in the bypass channel 2 is heated evenly, which is beneficial to improving the quality and heating effect of the hot air. With its ultra-high thermal conductivity, the graphene heater can convert electrical energy into thermal energy in a very short time, achieve rapid heating, greatly shorten the time required for zeolite regeneration, and improve the overall working efficiency of the dishwasher.

[0036] The bypass channel 2 is provided with a wiring groove 22 for the heater 3 to route outward. During the zeolite regeneration process of the dishwasher, the heater 3 generates hot air that flows in the bypass channel 2. The wiring groove 22 in the bypass channel 2 provides a channel for the circuit of the heater 3 to connect outward. The circuit is connected to an external power supply and other equipment through the wiring groove 22, which effectively prevents the hot air from escaping outward, concentrates the hot air on the proper path, maximizes the use of the heat generated by the heater 3, reduces energy waste, and improves the efficiency of zeolite regeneration.

[0037] Preferably, the connection between the bypass channel 2 and the main exhaust channel 1 is set as an arc transition. The arc transition design can make the hot air flow more smoothly from the bypass channel 2 to the main exhaust channel 1, avoiding the sharp turning of the airflow and the generation of vortices caused by right angles or sharp corners. In this way, the resistance of the airflow can be significantly reduced, so that the hot air can reach the zeolite drying module 7 more efficiently, and the aerodynamic performance and energy transfer efficiency of the entire drying and regeneration system are improved.

[0038] In this embodiment, a part of the exhaust main channel 1 is arranged on the side of the inner tank 8 of the dishwasher and extends vertically, and the bypass channel 2 is arranged on the side of the inner tank 8 of the dishwasher. Arranging the exhaust main channel 1 and the bypass channel 2 on the side of the inner tank 8 of the dishwasher can effectively release the space at the bottom of the dishwasher compared to setting them at the bottom. This makes it more convenient to install other important components at the bottom of the dishwasher, such as larger equipment such as water pumps and motors, thereby optimizing the spatial layout inside the dishwasher, improving the space utilization rate, and making the overall structure of the dishwasher more compact and reasonable. The exhaust main channel 1 extends vertically on the side, which can make the hot and humid gas extracted from the inner tank 8 more evenly distributed in various areas of the inner tank 8 during the rising process, avoiding the problem of excessive extraction of bottom air and poor air flow in the upper part caused by bottom exhaust. The bypass channel 2 can also better cooperate with the vertical exhaust main channel 1 on the side, so that the hot air can cover all corners more comprehensively when entering the inner tank 8, thereby achieving a more uniform drying effect, reducing the phenomenon of uneven drying of tableware, and improving user satisfaction with the quality of tableware drying.
