Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a washing machine water inlet system used for product washing tests. Background Art

[0002] Textiles are a kind of product made by weaving textile fibers, which are divided into two categories: woven fabrics and knitted fabrics. At present, during the production process of textiles, due to printing, dyeing, deep processing and other processes, many chemical raw materials, lines, etc. will remain in the fabrics. If the fabrics are not cleaned, they will cause harm to the human body, so the final cleaning of the fabrics is a necessary process. Therefore, after the textiles are made, they need to be cleaned, ironed and dried in a washing, ironing and drying machine. Usually, in order to promote the dissolution of detergents, improve the washing effect and sterilize clothes, it is necessary to use a washing machine to wash clothes with hot water.

[0003] There are two commonly used technical solutions in the prior art. The first is to add cold water to the washing machine first, and then heat the cold water through the heating device in the washing machine. The second is to directly add hot water to the washing machine. For the first technical solution, the heating of cold water is not only time-consuming but also seriously wastes electricity. In the second technical solution, cold water and hot water are usually supplied to the washing machine at the same time, and then the temperature of the hot water and cold water is detected by the temperature sensor. The opening and closing of the cold water valve and the hot water valve are controlled according to the temperature. When the water temperature in the washing machine is higher than the temperature expected by the user, the cold water valve is opened; when the water temperature in the washing machine is lower than the temperature expected by the user, the cold water valve is closed. However, due to the repeated opening and closing of the cold water valve, it is easy to damage the cold water valve, affecting the normal use of the washing machine. In addition, the water storage capacity of the household water heater is small and cannot meet the number of washing machines used in large-scale production. Alternatively, by first injecting hot water and then injecting cold water, a thermometer is used to test whether the water temperature reaches 40 degrees (±3 degrees), but if the water temperature is not reached, hot water or cold water is added, which takes a long time and the temperature cannot be controlled, resulting in a longer washing time for textiles.

An installation groove is provided inside the rotating plate, and a first water pipe for transporting hot water in the first hot water chamber to the second hot water chamber and a second water pipe for transporting cold water in the second cold water chamber to the first cold water chamber are respectively provided inside the installation groove.

[0009] As a preferred solution of the utility model, the hot water drain port is connected to the second hot water chamber, and the cold water drain pipe is connected to the first cold water chamber.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0026] like Figure 1 - Figure 5As shown, the utility model provides a water inlet system of a washing machine 1 for a product washing test, comprising a washing machine 1, a water heater 2, a water storage tank 3, a tap water pipe 4 and an automatic water return mechanism 5 for conveying cold water in the water storage tank 3 to the water heater 2, a first three-way pipe 6 is connected to the water inlet of the washing machine 1, and the two ends of the first three-way pipe 6 are respectively connected to a cold water inlet pipe 7 and a hot water inlet pipe 8, a hot water drain port 9 and a cold water drain pipe are respectively arranged on both sides of the bottom of the water storage tank 3, and the hot water inlet The other end of the pipe 8 is connected to the hot water drain outlet 9 of the water storage tank 3, a solenoid valve 11 is provided on the hot water inlet pipe 8, the outlet end of the tap water pipe 4 is connected to a second three-way pipe 12, one end of the second three-way pipe 12 is connected to the cold water inlet pipe 7, the other end of the second three-way pipe 12 and the water inlet end of the water heater 2 are both connected to a cold water conduit 14, the water outlet end of the water heater 2 and one side of the top of the water storage tank 3 are connected to a water inlet conduit 13, and the automatic water return mechanism 5 is respectively connected to the cold water drain pipe and the water heater 2 through the conduit.

[0027] When the utility model is in use, a solenoid valve 11 is installed on the hot water inlet pipe 8, and the cold water inlet pipe 7 and the hot water inlet pipe 8 are connected to form a water outlet through the first three-way pipe 6, so that the water outlet of two conventional faucets becomes the water outlet of one faucet. When the textile test samples are tested, the washing program is first set, and all washing machines 1 are numbered, and a control panel is installed to control the water outlet time and temperature of hot water and cold water. Then, a command is issued through the tablet computer to output hot water, and the water temperature is set to 40 degrees, the water reaching the temperature is stored in the water storage tank 3, which meets the use of 60 washing machines 1. After 40 liters of hot water are injected, it is automatically switched to normal temperature water, and there is no need to manually inject water and then test.

[0028] The water inlet process of the water inlet system is as follows: the tap water from the main pipeline enters the softening device for filtration and becomes soft water, and then the soft water passes through the tap water pipeline 4 and is transported to the cold water inlet pipe 7 and the cold water conduit 14 respectively through the second three-way pipe 12, so that a part of the cold water is directly supplied to the laundry room for water use, and the other part enters the water heater 2 through the cold water conduit 14 to be heated into hot water. Since there are many washing machines 1 in the laundry room, only one water heater 2 will lead to insufficient hot water supply. If multiple water heaters 2 are used, the cost is high, and the equipment installation area required is large, and it is difficult to ensure that the temperature of all hot water supplies is consistent. Therefore, by setting a water storage tank 3, the hot water is discharged through the water inlet conduit 13 and enters the water storage tank 3 for storage for use as hot water in the laundry room, and by setting an automatic water return mechanism 5, the remaining hot water in the water storage tank 3 is transported back to the water heater 2 for heating, thereby ensuring a stable hot water supply for a long time.

[0029] Furthermore, the inner wall of the water storage tank 3 is provided with an insulation layer, and a one-way valve is provided inside the cold water inlet pipe 7. By providing the insulation layer, the hot water inside the water storage tank 3 can be kept evenly, effectively reducing heat loss, and the one-way valve can prevent hot water from entering the cold water inlet pipe 7.

[0030] Compared with the prior art, the utility model can supply cold and hot water separately to all washing machines 1 in the laundry room, reducing time and energy consumption. Moreover, by setting the solenoid valve 11, the hot water is directly supplied after being heated to 40 degrees, avoiding the alternating mixing of cold and hot water in the washing machine 1 caused by repeated opening and closing of the cold water valve and the hot water valve, and the damage of the cold water valve and the hot water valve. Furthermore, by setting the storage tank 3 to store hot water, the temperature of the hot water supply can be accurately controlled, and the large capacity of the water storage tank 3 can meet the number of washing machines used in large-scale production at one time, reducing the washing time and improving the washing efficiency.

[0031] A partition plate 31 is provided inside the water storage tank 3, and the partition plate 31 divides the interior of the water storage tank 3 into a first accommodating chamber 32 and a second accommodating chamber 33. A rotating plate 34 is rotatably connected to the axis of the partition plate 31. Both ends of the rotating plate 34 are rotatably connected to the inner wall of the water storage tank 3 through bearings. One end of the rotating plate 34 passes through the water storage tank 3 and is fixedly connected to a driving device. Flip plates 35 are fixed on both sides of the rotating plate 34. All flip plates 35 respectively divide the interior of the first accommodating chamber 32 and the second accommodating chamber 33 into a first cold water chamber 36, a first hot water chamber 37, a second cold water chamber 38 and a second hot water chamber 39. An installation groove 40 is provided inside the rotating plate 34. A first water pipe 41 for transporting hot water in the first hot water chamber 37 to the second hot water chamber 39 and a second water pipe 42 for transporting cold water in the second cold water chamber 38 to the first cold water chamber 36 are respectively provided inside the installation groove 40.

[0032] The hot water drain port 9 is connected to the second hot water chamber 39 , and the cold water drain pipe 10 is connected to the first cold water chamber 36 .

[0033] One end of the water inlet conduit 13 is in communication with the first cold water chamber 36 inside the first accommodating chamber 32 .

[0034] When hot water is supplied normally, the water is heated by the water heater 2 and then transported to the first hot water chamber 37 in the first accommodating chamber 32 through the water inlet conduit 13. The hot water is transported to the second hot water chamber 39 through the first water delivery pipe 41. Then the hot water is transported to the washing machine 1 through the hot water inlet pipe 8. After the hot water supply is completed, the hot water remaining in the water storage tank 3 drops in temperature after being placed for a period of time and becomes cold water. When hot water is supplied next time, the hot water directly contacts the remaining cold water and the water temperature will drop and cannot reach 40 degrees. At this time, the hot water temperature in the water storage tank 3 cannot be controlled and cannot reach the required temperature for washing. Therefore, an automatic water return mechanism 5 is provided to transport the cold water back to the water heater 2 for reheating. The automatic water return mechanism 5 includes a water pump 51 and a cold water connecting pipe 52. The water inlet end of the water pump 51 is connected to the cold water drain pipe, and the two ends of the cold water connecting pipe 52 are respectively connected to the water outlet end of the water pump 51 and the water heater 2. After starting the water pump 51, the remaining cold water can be transported to the cold water connecting pipe 52 through the cold water drainage pipe and then input into the water heater 2. At this time, it takes a certain amount of time for the water pump 51 to pump water, and the water heater 2 cannot directly discharge the hot water into the water storage pipe. Therefore, the driving device drives the rotating plate 34 to rotate 180 degrees, so that the flip plate 35 turns over 180 degrees. When the flip plate 35 turns over, the hot water with a lowered temperature in the second hot water chamber 39 can be pushed into the second cold water chamber 38. At this time, the hot water continues to be transported to the first hot water chamber 37 and passes through the first water delivery pipe 4. 1 is transported to the second hot water chamber 39 for further transport, while the hot water in the second cold water chamber 38 is transported to the first cold water chamber 36 through the second water delivery pipe 42, and is pumped to the water heater 2 for reheating through the water pump 51, so that the cold water extraction and hot water supply can be carried out simultaneously, and the cold and hot water are separated and do not contact each other, which can ensure that the temperature of the newly supplied hot water reaches 40 degrees. Among them, when the flip plate 35 flips, only a small amount of cold water enters the first hot water chamber 37. Therefore, this small amount of cold water will not affect the overall temperature of the hot water after mixing with the newly supplied hot water.

[0035] Temperature sensors 43 are provided on both sides of the outer wall of the partition plate 31 close to the second cold water chamber 38 and the second hot water chamber 39. By providing temperature sensors on both sides of the rotating plate 34, the temperature of the cold water in the second cold water chamber 38 and the hot water in the second hot water chamber 39 can be monitored in real time, so as to judge whether the flip plate 35 needs to flip.

[0036] The outer walls of all the flip plates 35 are in contact with the inner wall of the water tank 3, and the outer walls of all the flip plates 35 are provided with a rubber layer to reduce the gap between the outer wall of the flip plate 35 and the inner wall of the water tank 3, so as to prevent cold water from dripping into the hot water through the gap.

[0037] It is worth noting that this system uses commercial water heaters 2, which are mainly aimed at the situation where the textile factory office building is built first and then moved in, and natural gas is not installed when the building is built. If natural gas is installed, the building needs to be renovated, which is a large amount of work.

[0038] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
