Description

Technical Field

[0001] This utility model belongs to the technical field of humidifying towel machines, specifically a moisture-proof pre-circulation humidifying towel machine. Background Technology

[0002] A towel machine is a device that humidifies compressed towels. During operation, it supplies hot or cold water to the compressed towels to moisten them, soften them, and maintain a suitable temperature. In other words, the towel machine has a system for heating the water. However, not every customer needs to use the compressed towels, so the machine may sit for a while before use. This causes the water in the pipes to cool down. Since the machine outputs a fixed amount of water each time, a significant amount remains in the pipes, meaning the water cannot be heated. Consequently, some cold water is directly supplied to the compressed towels, resulting in a lower temperature and insufficient softening of the towels.

[0003] In addition, current towel machines can only store one towel bucket, resulting in a small storage capacity of compressed towels that need to be added or replaced frequently. Furthermore, the bottom of the towel bucket is open, which is too close to the wet area of ​​the towel machine, making it easy for other stored compressed towels to become damp.

Detailed Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0041] Please refer to Figure 1-14 ;

[0042] Before use, the towel machine of this utility model can first introduce hot water into the pipe, so that the original cold water in the pipe flows back into the water tank 41. Specifically, it includes a shell 1, in which a storage component 2 is provided, which stores compressed towels. A feeding component 3 is installed below the storage component 2, and a placement position 32 is provided in the feeding component 3. A humidifying component 33 is provided in the placement position 32. When in use, a compressed towel is placed from the storage component 2 into the placement position 32. At this time, the placement position 32 is inside the shell 1, so the user will not come into contact with the compressed towel, avoiding scalding during heating and humidification. Since the water temperature in the pipe is low after the last use, and the amount of water used for heating and humidification is fixed, under normal circumstances, this part of cold water will be sprayed directly from the humidifying component 33. The temperature is too low, which will cause the compressed towel to not spread out. Therefore, a pre-circulation component 4 is provided.

[0043] Reference Figures 4-6 Specifically, it includes a water tank 41, which is connected to a water pump 42 via a pipe (not shown). The water pump 42 is connected to a heating element 43. The output end of the heating element 43 is connected to a control element via a hot water pipe 44. The control element is connected to a humidification element 33 via an output pipe 46. The control element is also connected to a return pipe 47, which is connected to the water tank 41. The control element controls the switching of the heating element, the return pipe 47, and the output pipe 46, and pre-circulates cold water back into the output pipe 46 to introduce hot water.

[0044] Initially, assuming there is water in the hot water pipe 44, return pipe 47, and output pipe 46, the water temperature is low. When needed, the control component closes, preventing water from flowing out of the output pipe 46. In other words, this cold water will not flow to the humidification component 33. The heating pipe and return pipe 47 are connected. Then, the water pump 42 starts working to continuously draw cold water from the water tank 41 and input it into the heating component 43. The temperature of this cold water increases significantly after passing through the heating component 43 and flows out through the heating pipe. While hot water is output to the heating pipe, the cold water originally located in the heating pipe and return pipe 47 will flow back to the water tank 41, thereby filling the return pipe 47 and the heating pipe with hot water. Then, the control component opens, disconnecting the heating pipe from the return pipe 47, or closing the return pipe 47 to prevent hot water from flowing into the water tank 41. At the same time, the output pipe 46 is connected to the hot water pipe 44, and then the hot water flows through the output pipe 46 to the humidification component 33, thereby wetting and softening the compressed towel.

[0045] It should be noted that although some cold water remains in the output pipe 46 during the above process, the distance is relatively short, so the amount of cold water remaining is very small and has a very small impact on the temperature, so it can be ignored.

[0046] Before use, this utility model uses internal circulation to return the cold water in the hot water pipe 44 and return pipe 47 to the water tank 41. The heating component 43 fills the hot water pipe 44 and return pipe 47 with hot water at a higher temperature. Finally, the control component is turned on to allow the hot water to flow from the output pipe 46 to the humidification component 33. This ensures that the water reaching the humidification component 33 maintains a high temperature, thereby allowing the compressed towel to be fully moistened and softened for customer use.

[0047] Preferably, it also includes an ozone-containing UV disinfection component, one end of which is connected to the water tank 41 via a pipe, and the other end is connected to the water inlet of the water pump 42 via a pipe. Since the water in the water tank 41 will be stored for a relatively long time, bacteria may grow. Therefore, after the water in the water tank 41 is drained, it first passes through the ozone UV disinfection component to eliminate odors and germs, etc., making it cleaner and more hygienic. In this embodiment, the ozone UV disinfection component can be a GPH843T5VH / 4 TOC ozone germicidal lamp.

[0048] Furthermore, the water output and heating occur simultaneously during use. Therefore, the water temperature initially flowing into the heating pipe is not high. For example, if the water needs to be heated to 40°C, the heating element 43 has not yet fully reached the heating temperature in the first 0.3 seconds. Thus, the initial portion of the water flowing into the heating pipe is not hot enough. Therefore, a temperature control probe 48 is provided at the output end of the heating element 43 to detect the temperature of the hot water entering the hot water pipe 44. At the same time, the return pipe 47 is connected to the heating element 43. When the output water temperature is detected to be insufficient, the water will still flow back into the water tank 41. When the temperature control probe 48 detects that the output water has reached the required temperature, it will send a signal to the central control system, and the timer will start, for example, a countdown of 2 seconds, causing the initial portion of the water to flow back into the water tank 41. After that, the control component opens, allowing the fully heated hot water to flow into the output pipe 46.

[0049] In another embodiment, the return pipe 47 is still connected to the water tank 41. Through multiple cycles, the temperature of all the cold water in the water tank 41 can be raised. Although it will take a lot of time, the same technical effect can still be achieved.

[0050] One embodiment of this utility model concerning a control component is described below. Figure 5 Specifically, it includes an electronic control valve 451, a heating tube and a return pipe 47 that meet and are connected to the input end of the control valve, and a pressure valve 452 is provided between the output ends of the return pipe 47.

[0051] When the electronic control valve 451 disconnects the output pipe 46, all the water is concentrated in the heating pipe and the return pipe 47. At this time, the hydraulic pressure will increase, and the water entering the return pipe 47 can return through the pressure valve 452. When the electronic control valve 451 is opened, some liquid flows out from the output pipe 46, causing the overall hydraulic pressure to drop. This prevents the water in the return pipe 47 from passing through the pressure valve 452, thus preventing return. Finally, the heated water will flow from the heating pipe to the output pipe 46.

[0052] Regarding another embodiment of the control component, see [reference]. Figure 6 It is a three-way electronic valve 453. The three-way electronic valve has three connection terminals, which are respectively connected to the heating tube, the return tube 47 and the output tube 46. When circulation is required, one end of the output tube 46 is disconnected and one end of the heating tube and the return tube 47 are connected. When water needs to be discharged, one end of the return tube 47 is disconnected and one end of the output tube 46 is opened, and then the heating tube and the output tube 46 are connected.

[0053] One embodiment of the present invention relates to the feeding component 3, see below. Figure 9 and Figure 10 Specifically, it includes a fixed plate 23, on which a movable block 31 is slidably connected. The movable block 31 is provided with a pushing component and a placement position 32. The humidifying component 33 is installed in the placement position 32. More specifically, a rack 34 is provided on the movable block 31. The rack 34 is meshed with a gear 35. The gear 35 is connected to a motor 36. The motor 36 can be installed on the housing 1. The motor 36 causes the gear 35 to rotate, causing the rack 34 to move back and forth, thereby realizing the pushing and retracting action to send the compressed towel out of the housing 1.

[0054] Furthermore, the humidification component 33 includes a water injection section 331, which is connected to a water pipe, and a partition net 332 is provided at its water outlet end. The partition net 332 disperses the water flow, making the water more evenly wet the compressed towel.

[0055] One embodiment of the present invention relates to the material storage component 2, see below. Figure 7 Figure 9Specifically, it includes at least two fixing parts 21 for placing towel bucket 5. The fixing parts 21 are hollowed out to allow compressed towels to pass through. An electric turntable 22 is located below the fixing parts 21. The electric turntable 22 is rotatably connected to the fixing plate 23. There is a gap 24 between the electric turntable 22 and the fixing plate 23 for placing a compressed towel. The height of the gap 24 is less than the height of the compressed towel. That is to say, the gap 24 cannot completely accommodate a compressed towel, or the compressed towel is flush with the surface of the electric turntable 22 after being placed in the gap 24. A first discharge port 225 is provided on the electric turntable 22. The first discharge port 225 can be placed below several fixing parts 21 respectively. A second discharge port 231 is provided on the fixing plate 23. By rotating, the first discharge port 225 corresponds to the second discharge port 231. The second discharge port 231 can correspond to the placement position 32.

[0056] It should be noted that the aforementioned fixing component 21 and fixing plate 23 are relatively stationary during operation, so the fixing component 21 and fixing plate 23 can be fixedly connected to the housing 1 of the towel machine.

[0057] There are two towel buckets 5 arranged symmetrically, while there is one discharge port 225. First, the two towel buckets 5 are placed into the two fixed parts 21 respectively. The compressed towels inside the towel buckets 5 slide down under the action of gravity, but due to the obstruction of the electric turntable 22, they will not slide out of the fixed parts 21, but will stay in the fixed parts 21.

[0058] During operation, the electric turntable 22 rotates, placing the discharge port 225 below one of the fixed components 21. At this time, one of the compressed towels slides out of the fixed component 21 and passes through the discharge port 225 into the gap 24 between the electric turntable 22 and the fixed plate 23. The next compressed towel will also slide into the fixed component 21, and so on. Meanwhile, the other fixed component 21 is still blocked by the electric turntable 22, so the compressed towel in the other towel bucket 5 will not slide out.

[0059] Then the electric turntable 22 rotates again. Since the height of the gap 24 is less than the height of the compressed towel, it drives the compressed towel located at the gap 24 to move until the first discharge port 225 corresponds to the second discharge port 231. The compressed towel will pass through the second discharge port 231 and enter the feeding component 3 in sequence. Finally, the feeding component 3 humidifies the compressed towel and pushes it out for the user to use. At the same time, the electric turntable 22 resets, so that the first discharge port 225 and the second discharge port 231 are misaligned.

[0060] Preferably, the positions of the two fixed components 21 and the discharge port 231 are distributed at 90° intervals, that is, the electric turntable 22 rotates 90° each time.

[0061] After the compressed towels in the current towel bucket 5 are used up, the rotation direction of the electric turntable 22 is controlled to make the discharge port 225 rotate towards another fixed part 21 and place it below to obtain compressed towels from another towel bucket 5. If the rotation direction of the electric turntable 22 is controlled, the simplest way is to use a counter to control the number of times the electric turntable 22 rotates in the same direction. That is, the number of compressed towels in the towel bucket 5 in the initial state is fixed and the same. For example, if the initial number of compressed towels in each towel bucket 5 is 10, the electric turntable 22 can rotate 10 times in the same direction and then rotate 10 times in the opposite direction. Of course, the compressed towels in the two towel buckets 5 can also be obtained in an alternating manner.

[0062] This invention enables the towel machine to reach the positions of several towel buckets 5 for material retrieval by rotating, thereby realizing the scheme of installing multiple towel buckets 5 in the towel machine, increasing the storage capacity of compressed towels. Secondly, by rotating the material retrieval method, the position for retrieving compressed towels can be far away from the humidification position in the feeding component 3, thereby avoiding unused compressed towels from being affected by moisture and becoming damp.

[0063] One embodiment of the present invention relates to an electric turntable 22, specifically including a turntable body 221. The center of the turntable body 221 is rotatably connected to a fixed plate 23. The outer periphery of the turntable body 221 is provided with teeth 222, which mesh with a gear 223. The gear 223 is installed at the output end of a motor 224, which is installed on the fixed plate 23. The motor 224 drives the gear 223 to rotate, which in turn pulls the teeth 222, thereby causing the turntable body 221 to rotate.

[0064] This utility model further describes the structure of the towel bucket 5, see reference. Figures 11-14 Specifically, it includes a cylinder 51. In this embodiment, the cylinder 51 can be arbitrary, such as a cuboid, a cylinder, etc. Of course, the space inside the fixed component 21 should also be adjusted accordingly. The cylinder 51 is provided with a channel 52 for placing several compressed towels, and has an inlet end 53 and an outlet end 54. The diameter of the channel is slightly larger than the diameter of the compressed towel. Since the humidification position of the compressed towel is different from the storage position, it will not affect the compressed towel in the towel bucket 5. Therefore, the compressed towel in the towel bucket 5 is still in block shape and has a relatively smooth surface, with less jamming during the falling process. An end cap 59 is provided at the inlet end 53, near the outlet end 54. Several claws 58 are rotatably connected to the outside of the cylinder 51. The claws 58 are evenly distributed and are fixed to the cylinder 51 by magnetic attraction. A support part 581 is provided at the lower end of the claws 58, and the support part 581 extends horizontally inward to the outlet end 54.

[0065] When compressed towels need to be placed into the towel container 5, open the end cap 59 to expose the inlet end 53. At the same time, the magnetic attraction causes several claws 58 to adhere tightly to the side of the cylinder 51, making the support part 581 protrude from the outlet end 54. Then, place several compressed towels into the placement channel 52 one by one. It is necessary to check whether the compressed towels are flat in the placement channel 52. Under the obstruction of the support part 581, the compressed towels should not fall from the outlet end 54. Then, close the end cap 59 and finally insert the towel container 5 into the fixing part. In component 21, after the towel bucket 5 is inserted into the fixed component 21, several claws 58 open, making the outlet end 54 unobstructed. The lowest compressed towel will fall into the fixed component 21. After the discharge port 225 is placed below the fixed component 21, the compressed towel enters the gap 24 between the electric turntable 22 and the fixed plate 23. When it is necessary to add compressed towels again, the towel bucket 5 is pulled out longitudinally from the towel machine. Under the action of gravity, several claws 58 rotate and reset, and are fixed to the towel bucket 5 again by magnetic attraction.

[0066] The towel bucket 5 in this utility model is no different from the existing technology in its use, but the overall structure of the towel bucket 5 is simplified by magnetic attraction, the number of parts used is greatly reduced, the assembly process is also simple and easy, and manufacturing costs and production time can be saved at the same time.

[0067] In this embodiment of the utility model, the side wall of the cylinder 51 is provided with a plurality of connecting blocks 55. The connecting blocks 55 are provided with a hinge part 57 and a fixing position 56 for fixing the magnet. The claw 58 is L-shaped. The cylinder 51, the connecting blocks 55, the hinge part and the fixing position 56 are integrally injection molded. The connecting blocks 55 protrude from the side wall of the cylinder 51, so there is a partial hollow between the claw 58 and the side wall of the cylinder 51, which is not compact enough. Therefore, the claw 58 is provided with a hinge part 582 and a clearance position 583. The clearance position 583 corresponds to the connecting block 55, and a magnet fixing position 584 is provided in the clearance position 583. The hinge part 57 and the hinge part 582 are rotatably connected. That is, the claw 58 near the side wall of the cylinder 51 forms a step-like structure, which can adapt to the difference in height between the cylinder 51 and the connecting blocks 55, making the structure more compact.

[0068] Preferably, the inside of the claw 58 is hollow, which can reduce the overall weight and save raw materials, thereby further reducing costs.

[0069] Furthermore, a downward inclined surface 585 is provided on one side of several supporting parts 581, and a guide structure is provided in the fixed part 21. When the towel bucket 5 is inserted, the guide structure and the inclined surface 585 can easily rotate and open the claws 58, so that the outlet end 54 is unobstructed. When the towel bucket 5 is pulled out of the towel machine, the inclined surface 585 is separated from the conical structure, and the claws 58 rotate and reset under the action of gravity and are fixed by magnetic attraction.

[0070] In this embodiment of the utility model, the fixing component 21 is cylindrical and its shape is adapted to the towel bucket 5. The upper part is the insertion end and the lower part is the feeding end. The inner side of the fixing component 21 near the bottom is provided with a guide groove 211 corresponding to the claw 58. The guide groove 211 is set on the outer periphery of the feeding end. The guide groove 211 can be inclined, and its inclination angle is greater than the inclination angle of the inclined surface 585, or it can be set longitudinally. When the lower end of the claw 58 enters the guide groove 211, it gradually rotates and opens under the action of the inclined surface 585, so that the outlet end 54 of the cylinder 51 is unobstructed and corresponds to the feeding end of the fixing component 21.

[0071] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
