[0029] The following is in conjunction with the appendix Figures 1-7 The embodiments of this utility model will be described in further detail below.

[0030] Fully automatic hot and cold water alternating bottle rinsing machine 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes a conveyor line 2, a hot water supply device 3, a cold water supply device 4, and two sets of spray devices 5. The conveyor line 2 is used to transport filled containers. Along its conveying direction, a heating zone 21 and a rinsing zone 22 are sequentially spaced along the conveyor line 2. Above each of the heating zone 21 and rinsing zone 22 is a set of spray devices 5, each equipped with multiple sets of water nozzles 54 for cleaning the outside of the containers. The hot water supply device 3 is located in the heating zone 21 and is connected to the corresponding spray device 5 to provide hot water. The cold water supply device 4 is located in the rinsing zone 22 and is connected to the corresponding spray device 5 to provide rinsing water.

[0031] Conveyor line 2 transports the filled and capped containers to heating zone 21. First, the outer surface of the containers is rinsed with hot water by spray device 5. The hot water can effectively soften the dried stains on the surface of the containers and perform the initial cleaning. Then, the containers enter rinsing zone 22, where spray device 5 uses cold water to clean the outer surface of the containers again. The container is cleaned while being transported, which saves time, has a high cleaning effect, and provides better cleaning quality.

[0032] In some embodiments, please refer to Figure 3 , Figure 5 The hot water supply device 3 includes a hot water tank 31, a hot water outlet pipe 32, and a hot water pump 33. The hot water tank 31 is located below the heating area 21. One end of the hot water outlet pipe 32 is connected to the hot water tank 31, and the other end of the hot water outlet pipe 32 is connected to the spray device 5. The hot water pump 33 is connected to the hot water outlet pipe 32 to draw hot water. The device has a simple structure and saves costs.

[0033] In order to heat the water in the hot water tank 31 to the set temperature at any time, the hot water supply device 3 also includes at least one heating element. The heating element is installed inside the hot water tank 31, has strong compatibility, and can ensure the water temperature in the hot water tank 31, thereby improving the quality and efficiency of cleaning. Of course, the heating element can also be set as a heating plate or heating wire structure for heating water, and its structure is not limited here.

[0034] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 6 The cold water supply device 4 includes a cold water tank 41, a cold water outlet pipe 42, and a cold water pump 43. The cold water tank 41 is located below the rinsing area 22. One end of the cold water outlet pipe 42 is connected to the cold water tank 41, and the other end is connected to the corresponding spray device 5. The structure is simple and cost-effective. The cold water pump 43 is connected to the cold water outlet pipe 42.

[0035] The cold water supply device 4 also includes a cold water inlet pipe 44, one end of which is connected to a cold water tank 41. The hot water outlet device also includes a hot water inlet pipe 34 and a three-way valve 35. One end of the hot water inlet pipe 34 is connected to the hot water tank 31, and the other end is connected to one port of the three-way valve 35. The other end of the cold water inlet pipe 44 is connected to another port of the three-way valve 35, and the third port of the three-way valve 35 is connected to an external water supply structure, which can ensure continuous water supply, save time, and improve work efficiency.

[0036] The cold water tank 41 and the hot water tank 31 are arranged adjacent to each other and are located between the cold water pump 43 and the hot water pump 33, resulting in a compact structure that reduces the space occupied. Both the inlet and outlet ends of the heating zone 21 and the rinsing zone 22 are equipped with partitions 23 to prevent water from splashing outside the zones, making it more environmentally friendly and preventing secondary contamination of the cleaned containers.

[0037] In some embodiments, both the cold water tank 41 and the hot water tank 31 are equipped with level sensing switches. These switches detect the minimum water level, facilitating timely water replenishment and improving cleaning quality. When the water levels in both the cold water tank 41 and the hot water tank 31 are above the minimum level, and the water in the hot water tank 31 is heated to a preset temperature, the cold water pump 43 and the hot water pump 33 start operating simultaneously, and the spray device 5 dispenses water. Both the cold water pump 43 and the hot water pump 33 are self-priming pumps.

[0038] When the liquid level in the cold water tank 41 or the hot water tank 31 is lower than the minimum level, or when the temperature of the hot water tank 31 is too low, the conveyor line 2 stops conveying water, and the self-priming pump stops pumping water. When the water level is too low, the corresponding water tank angle seat valve will open to add water. After the water level reaches the maximum level, the angle seat valve will close to stop adding water. When the water temperature in the hot water tank 31 is too low, the heating element will start to work and heat up. When the water temperature in the hot water tank 31 reaches the preset temperature, and the liquid levels in the cold water tank 41 and the hot water tank 31 are higher than the minimum level, the self-priming pump will continue to pump water, and the conveyor line 2 will resume conveying water, realizing a fully automatic hot and cold water alternating cleaning function.

[0039] In some embodiments, please refer to Figure 3 , Figure 4 The fully automatic hot and cold water alternating bottle rinsing machine 1 also includes a water collection tank 6 with an open top. The water collection tank 6 is located below the heating zone 21 and the rinsing zone, and the width of the opening side of the water collection tank 6 is greater than the width of the bottom of the tank. The bottom of the water collection tank 6 has a first outlet 61 and a second outlet 62, and a baffle 63 is installed between the first outlet 61 and the second outlet 62. The baffle 63 can isolate hot water from cold water, improving the recycling rate of hot water and saving costs. The first outlet 61 is connected to the hot water supply device 3, and the second outlet 62 is connected to the cold water supply device 4. The rinsed water can be recycled, saving costs and improving rinsing efficiency.

[0040] Specifically, both the hot water tank 31 and the cold water tank 41 have water inlets on their upper surfaces, and filter screens 7 are installed at the water inlets. The filter screens 7 are used to filter impurities in the cleaning water. After cleaning, the hot and cold water flows back to the corresponding hot water tank 31 and cold water tank 41 after being filtered by the filter screens 7. The first water outlet 61 and the second water outlet 62 are connected to the corresponding water inlets.

[0041] In some embodiments, please refer to Figure 4 , Figure 7 The spraying device 5 also includes a water supply pipe 51, a T-connector 52, and two branch pipes 53. One end of the water supply pipe 51 is connected to the corresponding hot water supply device 3 or cold water supply device 4, and the other end of the water supply pipe 51 is connected to one interface of the T-connector 52. The other two interfaces of the T-connector 52 are each connected to a branch pipe 53. Each branch pipe 53 and the water supply pipe 51 is equipped with multiple water nozzles 54. The water supply pipe 51 is positioned directly above the container, and a branch pipe 53 is correspondingly positioned on each side of the container. The multiple water nozzles 54 on the water supply pipe 51 and the two branch pipes 53 are all oriented towards the container on the conveyor line 2, which can ensure that the outer surface of the container is cleaned from all directions and angles, improving the cleaning quality.

[0042] Specifically, multiple water nozzles 54 are evenly distributed on the water supply pipe 51 and two branch pipes 53. The length direction of the water supply pipe 51 and the two branch pipes 53 is consistent with the conveying direction, which allows the conveyor line 2 to clean the containers without stopping during the cleaning process, thus increasing efficiency. Moreover, the spray angle of each water nozzle 54 is adjustable, enabling all-round cleaning of the containers and improving the cleaning quality.

[0043] During the cleaning process of the container's outer surface, the first stage of cleaning involves a high-pressure hot water spray rinse from the spray device 5 in conjunction with the hot water supply device 3 to soften the oil stains on the outer surface. The second stage involves a high-pressure cold water rinse from another spray device 5 in conjunction with the cold water supply device 4 to further clean the outer surface. This fully automatic hot and cold water alternating bottle rinsing machine 1 uses an alternating hot and cold water rinsing method, which can rinse the outer surface from multiple angles and in all directions, effectively ensuring that the container's outer surface is clean.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
