Description

Technical Field

[0001] This application relates to the field of cleaning machine technology, specifically to a heat pump energy-saving basket-type cleaning machine. Background Technology

[0002] In some traditional basket conveyor cleaning machines, there are multiple cleaning chambers and conveying mechanisms. The conveying mechanism will sequentially transport the utensils to be cleaned to each cleaning chamber for cleaning, and can also convey the cleaned utensils out of the cleaning chamber, making it convenient for staff to pick up the cleaned utensils.

[0003] However, in existing basket-type washing machines, dirty utensils are directly placed into the baskets, resulting in a large amount of solid food residue on the utensils. This food residue falls into the washing chamber after washing, leading to poor water cleanliness and preventing its recycling. This, in turn, increases water consumption and thus increases operating costs. If workers perform a rough wash on the dirty utensils before placing them in the baskets to reduce the amount of food residue entering the washing chamber, this requires workers to perform the rough wash elsewhere and then transport the rough-washed utensils to the washing machine for further fine washing. This increases transportation costs and reduces washing efficiency.

[0004] In addition, existing basket-type cleaning machines use traditional electric heating methods to heat the water in the cleaning machine, which consumes a lot of electricity and further increases the cost of use.

[0005] Therefore, there is room for further improvement in the existing cleaning machines. Utility Model Content

[0006] In view of this, and addressing the technical problems of existing basket-type cleaning machines lacking a pre-washing function, resulting in reduced water circulation, increased water consumption, and high power consumption for heating water, thus leading to higher operating costs, this application provides a heat pump energy-saving basket-type cleaning machine. This machine includes a pre-wash section to pre-wash soiled utensils, ensuring the cleanliness of the cleaning water and increasing the water circulation frequency to reduce water consumption and lower operating costs. Simultaneously, it includes a heat pump recovery mechanism to recover heat from the cleaning machine to heat the water, further reducing operating costs.

[0007] This application provides a heat pump energy-saving basket-type cleaning machine, comprising: The cleaning chamber is equipped with at least two spray arms; The pre-washing section, located at the entrance of the washing room, is used to pre-wash utensils; A conveyor mechanism is used to transfer equipment from the entrance to the exit of the cleaning chamber. Water supply system, used to supply water to the spray arms and pre-wash section; The heat pump recovery mechanism is used to recover the heat from the overflowing hot air in the cleaning chamber and to heat the liquid in the water supply mechanism.

[0008] Compared with existing technologies, the energy-saving basket-type washing machine of this application features a pre-wash section at the entrance of the washing chamber. This pre-wash section pre-washes the utensils, rinsing off large amounts of food residue before placing them into the basket and sending them into the washing chamber for automatic cleaning. This ensures that the utensils entering the washing chamber do not have excessive large food residue, resulting in higher cleanliness of the washing water from the spray arms within the washing chamber. This increases the frequency of water recycling within the washing chamber, thereby reducing water costs. Simultaneously, a heat pump recovery mechanism is included. This mechanism recovers the heat from the overflowing cleaning process and uses this heat to heat the liquid in the water supply system, saving energy consumption for heating the water in the washing machine and further reducing operating costs.

[0009] Preferably, the heat pump recovery mechanism includes: The heat collection chamber is located at the top of the cleaning chamber, with air intakes at both ends; The air intake assembly, located at the air inlet, is used to draw the hot air overflowing from the inlet and outlet of the cleaning chamber into the heat collection chamber. The heat pump assembly, located in the heat collection chamber, is used to recover heat from the hot air and exchange it with the water supply mechanism.

[0010] In this embodiment, the air intake component can quickly draw the hot air overflowing from the cleaning chamber into the heat collection chamber, reducing heat loss; while the heat pump component only consumes a small amount of electricity to recover the heat from the hot air and exchange it for heat to the water supply mechanism, thus saving energy.

[0011] Preferably, the cleaning chamber includes: The cleaning chamber is equipped with at least one cleaning arm, which is located near the entrance of the cleaning chamber. The rinsing chamber is equipped with at least one rinsing arm, which is located near the outlet of the rinsing chamber. The main wash water tank is connected to the water supply mechanism and is used to collect water from the washing chamber and rinsing chamber, and to supply water to the washing arm.

[0012] In this embodiment, the main wash tank can temporarily store the water used for washing in the washing chamber and rinsing chamber, and supply water to the washing arm, thereby realizing water circulation in the washing arm and reducing water costs.

[0013] Preferably, the pre-wash section includes: The faucet is connected to the water supply system; The pre-wash tub, located below the faucet, has space to accommodate utensils; The drain pipe is located at the bottom of the pre-wash tank and is used to drain the dirt and grime from the pre-wash tank.

[0014] In this embodiment, the faucet is directly connected to the water supply mechanism, enabling the use of hot water and quickly rinsing away dirt from the utensils; while the pre-washing tank provides space for utensils, making it convenient for staff to pre-wash the utensils in the pre-washing tank with water.

[0015] Preferred options also include: A receiving station, located at the exit of the washing room, is used to receive dish baskets; The controller, located at the side of the cleaning chamber, is used to control the operating status of the cleaning machine.

[0016] In this embodiment, the receiving platform can receive the cleaned utensils, and the controller allows the staff to easily control the operating status of the cleaning machine, improving the flexibility of the cleaning machine.

[0017] Preferably, the water supply mechanism includes: A buffer tank is used to store water. The first supply pipe is connected to the outlet of the buffer water tank and is at least partially located inside the heat pump recovery mechanism. The second supply pipe is connected to the outlet end of the first supply pipe and is used to supply water to at least one rinsing arm. The third supply pipe has its inlet end connected to the outlet end of the first supply pipe, and its outlet end connected to the inlet end of the buffer water tank.

[0018] In this embodiment, the buffer tank can store the water used by the cleaning machine. The first supply pipe can guide the liquid in the buffer tank to the heat pump recovery mechanism for heating. The third supply pipe can guide the heated liquid back to the buffer tank to preheat the cold water in the buffer tank, thereby increasing the temperature of the liquid in the buffer tank. This allows the water in the buffer tank to reach the washing temperature more quickly when it is heated by the heat pump recovery mechanism after circulating to the first supply pipe, thus improving the washing effect.

[0019] Preferred options also include: A heating device for heating the liquid in the second supply pipe; The first pump body is connected in series with the first and second supply pipes and in parallel with the third supply pipe; The third water supply pipe is at least partially located inside the main washing water tank, and the buffer water tank is located at the lower end of the receiving platform.

[0020] In this embodiment, the heating device can heat the liquid in the second supply pipe to increase the temperature of the rinsing water and ensure the rinsing effect.

[0021] Preferred options also include: Waste tank, located inside the cleaning chamber, is used to collect solid food residue inside the cleaning chamber; The cleaning base plate is located at the bottom of the cleaning chamber and has a first through hole that connects to the main washing water tank. The fourth water supply pipe is connected to the outlet of the main washing water tank and is used to supply water to the washing arm. The cleaning base plate is inclined in the horizontal direction and tilts downward toward the waste tank.

[0022] In this embodiment, the cleaning base plate is inclined, so that the solid-liquid mixture on the cleaning base plate can flow to the waste tank under the action of gravity. The waste tank can store solid waste, so that the cleanliness of the liquid that finally enters the liquid inlet is better. This makes the liquid supplied by the main washing water tank to the rinsing arm and the washing arm cleaner, further improving the water circulation cycle of the cleaning machine and further saving water.

[0023] Preferred options also include: The rinsing water tank is located inside the main rinsing water tank, near the rinsing chamber, and is used to collect the liquid in the rinsing chamber. The fifth supply pipe is connected to the outlet of the rinsing water tank and is used to supply water to at least one rinsing arm. The rinsing base plate is located at the bottom of the rinsing chamber and slopes downward toward the rinsing water tank.

[0024] In this embodiment, the liquid in the rinsing tank can be directly supplied to the rinsing arm, realizing water recycling while ensuring that the cleanliness of the water used in the rinsing arm is maintained to a certain extent.

[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0030] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0031] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0032] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 5 illustrate.

[0033] This application provides a heat pump energy-saving basket-type cleaning machine (hereinafter referred to as the cleaning machine) for cleaning tableware and utensils.

[0034] like Figures 1 to 5 As shown, the cleaning machine includes a cleaning chamber 1, a heat pump recovery mechanism, a conveying mechanism 3, and a water supply mechanism. The water supply mechanism supplies water to the entire cleaning machine. A spray arm is installed inside the cleaning chamber 1 and is connected to the water supply mechanism, which supplies water to the spray arm. The conveying mechanism 3 passes through the cleaning chamber 1 and is used to convey the dish rack from the inlet end to the outlet end of the cleaning chamber 1. The heat pump recovery mechanism is located at the top of the cleaning chamber 1 and is used to recover the hot air overflowing from the inlet and outlet ends of the cleaning chamber 1. The heat from the recovered hot air is then transferred to the liquid in the water supply mechanism to heat the liquid, thereby saving energy consumption for heating the water in the cleaning machine and further reducing the operating cost of the cleaning machine.

[0035] Specifically, the entrance of the washing chamber 1 is equipped with a pre-wash section 2. The pre-wash section 2 pre-washes the utensils, rinsing off large amounts of food residue. The utensils are then placed in a dish rack and sent into the washing chamber 1 for automatic washing. This ensures that the utensils entering the washing chamber 1 do not have excessive large food residue, resulting in higher cleanliness of the washing water from the spray arms within the washing chamber 1. This increases the number of times water is recycled within the washing chamber 1, thereby reducing water costs. For example, Figure 1 , Figure 2 , Figures 4 to 5 As shown, the pre-wash section 2 includes a faucet 16, a pre-wash tank 17, and a drain pipe 18. The pre-wash tank 17 has a receiving space for holding utensils and liquids, making it convenient for staff to place utensils in the pre-wash tank 17 for soaking, making it easier to rinse off food residue and improve the cleaning effect. The faucet 16 is located above the pre-wash tank 17, with its outlet facing the pre-wash tank 17. The faucet 16 is connected to the water supply mechanism, which can directly put heated water from the water supply mechanism into the pre-wash tank 17. The hot water can quickly rinse the dirt on the utensils, improving the cleaning effect. The drain pipe 18 is located at the bottom of the pre-wash tank 17, through which the dirt in the pre-wash tank 17 can be discharged with water.

[0036] Among them, such as Figures 1 to 5 As shown, the outlet end of the washing chamber 1 is provided with a receiving platform 19. The platform height of the receiving platform 19 is slightly lower than the top of the conveying mechanism 3, so that the washed dish basket can be pushed onto the receiving platform 19 by the conveying mechanism 3, so that the staff can take the washed dishes from the dish basket.

[0037] Furthermore, the heat pump recovery mechanism will be described in more detail; such as... Figures 1 to 5As shown, the heat pump recovery mechanism includes a heat collection chamber 4, an air intake assembly 5, and a heat pump assembly 6. The heat collection chamber 4 is located directly above the cleaning chamber 1 and is used to contain the hot air overflowing from the cleaning machine. The heat pump assembly 6 is installed inside the heat collection chamber 4 and can recover the heat of the hot air inside the heat collection chamber 4 and transfer the recovered heat to the water in the cleaning machine to achieve heat recovery and utilization and reduce heat waste. The heat collection chamber 4 has two air intakes at opposite ends, namely a first air intake and a second air intake. The first air intake is located above the inlet end of the cleaning chamber 1, and the second air intake is located above the outlet end of the cleaning chamber 1. There are two air intake assemblies 5, respectively located at the ends of the first air intake away from the heat collection chamber 4 and the second air intake away from the heat collection chamber 4. The air intake assembly 5 is connected to the heat collection chamber 4, thereby drawing the hot air overflowing from the inlet and outlet ends of the cleaning chamber 1 into the heat collection chamber 4. This can accelerate the speed at which the hot air overflowing from the inlet and outlet ends of the cleaning chamber 1 enters the heat collection chamber 4, reduce the time the hot air stays in the chamber, and reduce the heat loss of the hot air.

[0038] At the same time, such as Figures 1 to 5 As shown, the first and second air intake ports are located outside the cleaning chamber 1, so that the hot air in the cleaning chamber 1 will not directly rise into the heat collection chamber 4. During the process of the hot air overflowing outward in the horizontal direction in the cleaning chamber 1, then moving upward in the vertical direction to the air intake component 5, and then moving horizontally back into the heat collection chamber 4, the flow path of the hot air is relatively tortuous, which increases the obstruction of the hot air directly entering the heat pump component 6. This causes the condensate generated by the hot air to remain in the external space or in the air intake component 5, reducing the amount of condensate entering the heat pump component 6, thereby reducing the adverse effects of condensate on the heat pump component 6 and improving the recovery efficiency and service life of the heat pump component 6.

[0039] On the other hand, the first air intake is located above the outlet of the cleaning chamber 1, and the second air intake is located directly above the inlet of the cleaning chamber 1. This can shorten the distance that steam needs to travel from the cleaning chamber 1 to the heat collection chamber 4, thereby reducing unnecessary heat loss of the hot air in the external environment.

[0040] In this application, as Figure 2 As shown, the heat pump assembly 6 includes an evaporator, a compressor, a condenser, and a gas-liquid separator. The evaporator, compressor, and condenser together form a heat recovery system. The heat pump assembly 6 of this application adopts the principle of air source heat pump, which will not be described in detail here.

[0041] Furthermore, such as Figures 2 to 4As shown, the heat collection chamber 4 has buffer chambers 7 at both ends. The heat collection chamber 4 is formed by a heat collection shell and is roughly rectangular in shape. The buffer chambers 7 are formed by a buffer shell and are roughly right-angled trapezoidal in shape. A mounting plate 8 is provided between the buffer chamber 7 and the heat collection chamber 4. The mounting plate 8 is parallel to the vertical direction and is used to install the air intake assembly 5, which includes a fan. The mounting plate 8 has multiple second air inlets, and the hot air from the cleaning machine enters the heat collection chamber 4 from the fan or the second air inlets.

[0042] An air inlet baffle 9 is provided at the end of the buffer chamber 7 away from the heat collection chamber 4. The air inlet baffle 9 has multiple first air inlets. The air inlet baffle 9 is inclined in the vertical direction. The included angle between the air inlet baffle 9 and the mounting plate 8 is an obtuse angle. The bottom of the air inlet baffle 9 is connected to the top edge of the cleaning chamber 1. The upper end of the air inlet baffle 9 extends away from the heat collection chamber 4 to block and cover the vertical direction of the inlet and outlet of the cleaning chamber 1. This allows most of the hot air rising in the vertical direction to pass through the first inlet and enter the air inlet chamber as much as possible. This can prevent the loss of hot air and increase the probability of hot air entering the heat collection chamber 4, thereby improving the heat recovery efficiency.

[0043] The first air inlet can be a round hole or a strip-shaped hole, and the second air inlet can be a round hole or a strip-shaped hole. In this embodiment, the first air inlet is a strip-shaped hole, which can increase the interception effect of condensate; the second air inlet is a round hole, which allows hot steam to quickly enter the heat collection chamber 4.

[0044] In this embodiment, the distance between the bottoms of the two air intake baffles 9 is equal to the length of the cleaning chamber 1, and the distance between the tops of the two air intake baffles 9 is greater than the length of the cleaning chamber 1, so that the hot air flowing out of the outlet and inlet of the cleaning chamber 1 can be absorbed by the heat recovery device as much as possible.

[0045] Based on any of the above embodiments, the cleaning chamber 1 will be further described; such as Figures 3 to 5As shown, the washing chamber 1 includes a washing chamber 10, a rinsing chamber 11, and a main washing water tank 12. The washing chamber 10 and the rinsing chamber 11 are arranged side by side, with the rinsing chamber 11 located near the outlet end of the washing machine and the washing chamber 10 located near the inlet end of the washing machine. The washing chamber 1 has an upper and lower structure, with the washing chamber 10 and the rinsing chamber 11 in the upper part, and the main washing water tank 12 and part of the water supply mechanism located in the lower part. The washing chamber 10 is equipped with washing arms 13, including an upper washing arm 13 and a lower washing arm 13, which are distributed vertically. The rinsing chamber 11 is equipped with rinsing arms, including a pre-rinsing arm 14 and a final rinsing arm 15, which are spaced apart along the direction of dish movement, with the final rinsing arm 15 located near the washing machine. The outlet is set up; of course, the final rinse arm 15 and the pre-rinse arm 14 also include upper and lower spray arms; the buffer water tank 21 is used to store the water used by the washing machine. The buffer water tank 21 is located below the receiving platform 19 and is offset from the washing chamber 1; the main wash water tank 12 is located in the washing chamber 1. The main wash water tank 12 is connected to the water supply mechanism. The liquid heated by the water supply mechanism through the heat pump recovery mechanism can enter the main wash water tank 12 to preheat the liquid in the main wash water tank 12; at the same time, the main wash water tank 12 is also used to receive the liquid flowing out of the pre-rinse arm 14 and the final rinse arm 15 and store it temporarily. At the same time, it continues to supply liquid to the pre-rinse arm 14 and the washing arm 13, so that the washing water sprayed by the rinsing arm can continue to be recycled, thereby saving water.

[0046] The upper and lower parts of the cleaning chamber 1 are separated by a base plate. The cleaning base plate 28 is located below the cleaning chamber 10, and the rinsing base plate 29 is located below the rinsing chamber 11. In the vertical direction, the cleaning base plate 28 is the lowest, and the rinsing base plate 29 is higher than the cleaning base plate 28, so that the liquid after cleaning in the cleaning chamber 10 will not easily flow to both ends. The middle base plate of the cleaning base plate 28 is provided with multiple through holes, so that after the cleaning arm 13 sprays out the cleaning equipment, the liquid flows directly into the main washing water tank 12 through the through holes.

[0047] like Figure 3 As shown, the washing base plate 28 consists of three plates arranged sequentially along the direction of bowl movement. The middle plate has the lowest height, and the liquid inlet is located on the side plate near the rinsing chamber 11. The middle plate is located directly below the washing arm 13, and its width is greater than that of the washing arm 13. This allows the dirt washed out by the washing arm 13 to fall directly onto the middle plate. Because the middle plate is lower, solid food residue remains on it and cannot easily pass through the side plates to the liquid inlet, thus ensuring the cleanliness of the liquid in the main washing tank 12.

[0048] like Figure 3As shown, a drain pipe 18 is provided on the bottom plate of the cleaning base plate 28 near the inlet base plate. The drain pipe 18 is used to drain the liquid in the cleaning chamber 10. At the same time, the water inlet of the drain pipe 18 is set at a height greater than the inlet base plate, which can also serve as an overflow pipe.

[0049] In this embodiment, such as Figure 5 As shown, a waste trough 27 is provided at the rear end of the cleaning base plate 28. The waste trough 27 is used to collect solid food residue on the intermediate base plate, so that the cleanliness of the liquid flowing into the main washing water tank 12 through the first through hole is relatively high. The cleaning base plate 28 is inclined in the horizontal direction, and the front end of the cleaning base plate 28 is set at a greater height than the rear end. This allows the solid-liquid mixture on the cleaning base plate 28 to flow to the waste trough 27 under the action of gravity. The waste trough 27 can store solid waste, so that the cleanliness of the liquid that finally enters the liquid inlet is relatively good. This makes the liquid supplied by the main washing water tank 12 to the pre-rinsing arm 14 and the cleaning arm 13 cleaner, further improving the water circulation cycle of the washing machine and further saving water.

[0050] Among them, such as Figure 3 As shown, the bottom plate of the rinsing base plate 29 is inclined, and its height angle near the washing chamber 10 is relatively low, so that the liquid washed in the rinsing chamber 11 can flow quickly into the washing base plate 28.

[0051] In this embodiment, the main washing water tank 12 mainly receives the washing water from the rinsing chamber 11 and the cleaning chamber 10, and can simultaneously supply water to the pre-rinsing arm 14 and the cleaning arm 13.

[0052] In another optional embodiment of this application, such as Figure 3 , Figure 5 As shown, a rinsing water tank 30 is provided inside the main washing water tank 12. The rinsing water tank 30 is located below the bottom plate with the liquid inlet, that is, the side bottom plate of the cleaning bottom plate 28 near the rinsing chamber 11 is the top plate of the rinsing water tank 30. This side bottom plate has multiple through-holes, allowing the water used for rinsing to flow into the rinsing water tank 30 through these through-holes. Correspondingly, the middle bottom plate of the cleaning bottom plate 28 has multiple through-holes, allowing the liquid sprayed out by the cleaning arm 13 to flow directly into the main washing water tank 12 through the first through-holes. Figure 3 As shown, since the middle bottom plate and the side bottom plate of the cleaning bottom plate 28 are arranged side by side, and the middle bottom plate is lower than the side bottom plate, the cleaning water of the cleaning arm 13 flows into the main washing water tank 12 through the first through hole, and the rinsing arm water flows into the rinsing water tank 30 through the second through hole, so as to reduce the probability of rinsing water and cleaning water mixing; and the rinsing water tank 30 is used to supply water to the pre-rinsing arm 14, which can ensure the cleanliness of the water used in the pre-rinsing arm 14.

[0053] In this embodiment, the bottom plate of the rinsing water tank 30 and the bottom plate of the main washing water tank 12 are spaced apart vertically. The bottom plate of the rinsing water tank 30 is provided with a first connecting port, which is used to connect the rinsing water tank 30 and the main washing water tank 12. That is, the liquid in the cleaning chamber 1 can enter the rinsing water tank 30 through the liquid inlet, and then enter the main washing water tank 12 through the first connecting port on the rinsing water tank 30. However, it should be noted that the first connecting port is provided with a sealing plug, which blocks the first connecting port, so that the rinsing water tank 30 and the main washing water tank 12 are not connected. Under normal circumstances, the rinsing water tank 30 and the main washing water tank 12 are relatively independent. When it is necessary to discharge the liquid in the rinsing water tank 30 to the main washing water tank 12, the sealing plug can be removed, so that the rinsing water tank 30 and the main washing water tank 12 can be connected, and then the main washing water tank 12 can use the water from the rinsing water tank 30.

[0054] In this embodiment, the rinsing water tank 30 mainly receives the washing water from the rinsing chamber 11 to supply water to the pre-rinsing arm 14; the main washing water tank 12 mainly receives the washing water from the cleaning chamber 10 to supply water to the cleaning arm 13. This ensures the water supply needs of the cleaning arm 13 and the pre-rinsing arm 14 are met, while also ensuring the cleanliness of the water used in the cleaning arm 13 and the pre-rinsing arm 14, thereby improving the washing effect on the utensils. Furthermore, since the rinsing water tank 30 mainly receives the water from the rinsing chamber 11 and only supplies water to the pre-rinsing arm 14, the number of times the washing water in the rinsing chamber 11 is recycled can be increased, thereby saving costs.

[0055] The water supply mechanism will be further described based on any of the above embodiments; such as... Figure 3 , Figure 4 As shown, the water supply mechanism includes a buffer water tank 21, a first supply pipe 22, a second supply pipe 23, and a third supply pipe 24. The buffer water tank 21 is located below the receiving platform 19, thereby making reasonable use of the space below the receiving platform 19 and reducing the overall volume occupied by the cleaning machine. The buffer water tank 21 provides storage space for the water used by the cleaning machine. The inlet end of the first supply pipe 22 is connected to the outlet end of the buffer water tank 21, and the first supply pipe 22 is at least partially located within the heat pump recovery mechanism, thereby allowing the liquid in the first supply pipe 22 to be heated by the heat pump recovery mechanism.

[0056] The inlet ends of the second supply pipe 23 and the third supply pipe 24 are connected to the outlet end of the first supply pipe 22. The second supply pipe 23 and the third supply pipe 24 are connected in parallel. The outlet end of the second supply pipe 23 is connected to the final rinsing arm 15, thereby supplying water to the final rinsing arm 15. A portion of the heated liquid enters the final rinsing arm 15 directly through the second supply pipe 23, resulting in a higher spray temperature in the final rinsing arm 15. This ensures the cleanliness and high-temperature effect of the water used when the dishes are finally washed, thus guaranteeing the hygiene of the dishes.

[0057] The outlet of the third supply pipe 24 is connected to the inlet of the buffer water tank 21. That is, a portion of the heated liquid in the first supply pipe 22 returns to the buffer water tank 21 through the third supply pipe 24, which can preheat the cold water in the buffer water tank 21 and increase the temperature of the liquid in the buffer water tank 21. This allows the liquid in the buffer water tank 21 to be circulated back to the first supply pipe 22 and heated by the heat pump recovery mechanism to increase its temperature more quickly, so that the water used in the cleaning machine can reach the washing temperature more quickly and improve the washing effect.

[0058] In this embodiment, the third supply pipe 24 is at least partially located inside the main wash water tank 12, thereby enabling the liquid in the third supply pipe 24 to exchange heat with the main wash water tank 12. When the temperature of the main wash water tank 12 is high, the temperature of the liquid flowing into the buffer water tank 21 is also high, which can accelerate the increase in the temperature of the liquid in the buffer water tank 21, preheat the cold water in the buffer water tank 21, and increase the temperature of the liquid in the buffer water tank 21. This allows the liquid in the buffer water tank 21 to be circulated to the first supply pipe 22 next time and heated by the heat pump recovery mechanism, which can quickly raise the temperature and allow the water used in the washing machine to reach the washing temperature more quickly, thus improving the washing effect. Alternatively, when the temperature of the main wash water tank 12 is low, it can accelerate the increase in the temperature of the liquid in the main wash water tank 12, so that the water supply temperature from the main wash water tank 12 to the pre-rinse arm 14 and the washing arm 13 can quickly reach the washing requirements.

[0059] The third supply pipe 24, located inside the main wash water tank 12, is configured with an S-shaped structure, which increases the contact area and contact path between the third supply pipe 24 and the liquid in the main wash water tank 12, thereby improving the heat exchange effect. It should be noted that although the third supply pipe 24 is at least partially located inside the main wash water tank 12, the liquid in the third supply pipe 24 does not come into contact with the liquid in the main wash water tank 12. The two exchange heat through the pipe wall of the third supply pipe 24.

[0060] Furthermore, such as Figure 3 , Figure 4 As shown, the water supply mechanism also includes a heating device 25, which can heat the liquid in the second supply pipe 23, so that the water in the final rinse arm 15 is heated twice, thereby ensuring that the temperature of the rinsing water in the final rinse arm 15 can meet the washing requirements, and thus ensuring the washing effect.

[0061] The heating device 25 includes a heating cylinder and a heating tube. The heating tube is an electric heating structure and is located inside the heating cylinder. The heating cylinder is connected in series in the second supply pipe 23. The heating tube is used to heat the liquid inside the heating cylinder to ensure that the temperature of the liquid flowing to the final rinsing arm 15 meets the washing requirements.

[0062] like Figure 2As shown, the water supply mechanism also includes a first pump body 26, which is connected in series between the first supply pipe 22 and the second supply pipe 23. The first pump body 26 is used to apply power to the liquid in the first supply pipe 22, so that the liquid in the first supply pipe 22 can flow to the final rinsing arm 15 through the second supply pipe 23, ensuring smooth liquid supply to the final rinsing arm 15 and thus ensuring the rinsing effect. At the same time, the first pump body 26 is connected in parallel with the third supply pipe 24, that is, the third supply pipe 24 is connected in parallel with the second supply pipe 23.

[0063] Furthermore, such as Figure 3 , Figure 4 As shown, the water supply mechanism also includes a fourth supply pipe 31 and a fifth supply pipe 32; the fourth supply pipe 31 is used to supply water to the washing arm 13, and its inlet end is connected to the outlet end of the main washing water tank 12, and its outlet end is connected to the washing arm 13; the fifth supply pipe 32 is used to supply water to the pre-rinse arm 14, and its inlet end is connected to the outlet end of the rinsing water tank 30, and its outlet end is connected to the pre-rinse arm 14.

[0064] In any of the above embodiments, the cleaning machine can be further expanded; such as... Figures 1 to 2 As shown, the cleaning machine also includes a controller 20 and a temperature sensor. The controller 20 is connected to the power supply, heat pump recovery mechanism, water supply mechanism, heating device 25, etc. The controller 20 includes a control panel, which is located on the front side of the cleaning machine. The operating status of the heat pump recovery mechanism, water supply mechanism, and heating device 25 can be controlled through the control panel, thereby improving the ease of use of the cleaning machine.

[0065] Temperature sensors are appropriately installed in various sections of the water supply mechanism. They are used to detect the heating temperature of the water used by the heat pump recovery mechanism and heating device 25 for the cleaning machine. They can also transmit the detected temperature to the controller 20. The detected temperature can be directly read on the control panel, which allows the staff to quickly and easily control the water temperature of the cleaning machine and thus control the heat pump recovery mechanism and heating device 25 in a timely manner.

[0066] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.
