This device has a simple structure, is lightweight, consumes little power, is highly efficient, and has a large pressure difference between high and low pressures. It effectively creates low or high pressure within the space of external equipment, making it widely applicable. Furthermore, it utilizes the pressure reduction effect to extract polluted gases and bacteria / mold into the atmosphere, which is beneficial for food preservation.

Its high-pressure or low-pressure space chamber consists of a pressure-resistant shell 39 and a safety door. The refrigerator uses a low-pressure environment created in the cold storage compartment of the refrigeration equipment at low temperatures to expel odors from food or medicine. Bacteria are inhibited from surviving in a low-oxygen environment, and the food is frozen under normal pressure to extend its shelf life. A high and low pressure regulating device 1 is added to the refrigerator-like refrigeration equipment in this embodiment, which is energy-saving, environmentally friendly, and pollution-free. Figure 4 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figures 5-6 It is a high and low pressure device 1 with two pressure-controlling housings 6; the following is in conjunction with Figure 1 , Figure 4 This implementation method is described below;

[0149] The refrigerator of this embodiment includes a pressure-resistant shell 39, an internal groove 36, a pressure-resistant sealing device 80, a pressure regulating valve 37, a pressure-resistant internal door 35, an observation window 38, a dryer filter 28, a capillary tube 29, a refrigeration system 30, a refrigerator shell 31, a safety valve 32 (limiting the maximum air pressure and limiting the minimum air pressure), a refrigerator pressure-resistant inner shell 33, a refrigerator low-pressure resistant upper door, a freezer compartment or refrigerator compartment, i.e., a cold storage compartment, and a refrigeration system 30.

[0150] In this embodiment, a high-low pressure device 1 is provided on the refrigerator. The high-low pressure device 1 is composed of a moving device 4, a pressure rod 2, a pressure body 7, a pressure housing 6, and valves. The valves include a suction valve and a pressurizing valve. The high-low pressure device 1 manufactures all equipment that uses a high-pressure space or a low-pressure space.

[0151] The cold storage compartment of various refrigeration equipment such as refrigerators uses a low-pressure, low-oxygen, low-pressure gas or fluid, and low-temperature environment (lower than atmospheric pressure) to reduce the activity of bacteria and microorganisms, thereby achieving the purpose of preserving food and removing odors.

[0152] The various refrigeration equipment such as refrigerators are integrally or connected to form an integral connection with a high and low pressure device 1; the bottom outer periphery of the pressure housing 6 of the high and low pressure device 1 is integrally or connected to form an integral connection with a pressure valve 15 that generates pressure higher than the atmospheric environment and a pressure suction valve 11 that generates pressure lower than the atmospheric environment.

[0153] The pressure valve 15 is provided with an air outlet (A') and the suction valve 11 is provided with an air inlet (B').

[0154] The suction valve 11, which is integrally or connected to and formed as an integral part of the high and low pressure device 1, discharges the gas in the cold storage chamber, forming a low-pressure cold storage chamber where the gas pressure in the cold storage chamber is lower than the external atmospheric pressure.

[0155] The high and low pressure device 1 is integrally or integrally connected to and formed as a single unit with a pressure-controlling housing 6; a pressure-controlling body 7 is provided on the inner side of the pressure-controlling housing 6, which reciprocates axially along the inner wall of the pressure-controlling housing 6; a pressure-controlling rod 2 is integrally or integrally connected to and formed as a single unit via a pressure-controlling body shaft 18 in a dynamic fit; the other end of the pressure-controlling rod 2 is integrally or integrally connected to and formed as a single unit, which is dynamically fitted to the motion device 4;

[0156] The pressure regulating body 7 reciprocates axially along the hole wall inside the pressure regulating housing 6 until the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is at its maximum and the gas is at its maximum. At this point, the pressure regulating body 7 compresses the space of the internal gas to form a high pressure. Alternatively, when the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is at its minimum and the gas is at its minimum, the pressure regulating body 7 expands the space of the internal gas to form a low pressure. A sealing ring 8 is provided on the pressure regulating body 7.

[0157] The suction valve 11 has a suction valve rotating body 9 integrally or connected to it in a dynamically fitted manner within its cavity 10. A check valve 13 is installed within the suction valve rotating body 9. The suction valve rotating body 9 is integrally or connected to it in a dynamically fitted manner within the cavity 10 of the suction valve 11. The pressurizing valve cavity 16 has a pressurizing valve rotating body 17 integrally or connected to it in a dynamically fitted manner. A check valve 13 is installed within the pressurizing valve rotating body 17. A valve shaft 12 is installed on the check valve 13. A spring 14 is installed between the check valve 13 and the suction valve rotating body 9. A spring is installed between the check valve and the pressurizing valve rotating body 17. The pressurizing valve rotating body 17 is integrally or connected to it in a dynamically fitted manner within the pressurizing valve cavity 16.

[0158] The rotating body has a rotating handle integrally or connected to the top end and is integrally provided with a rotating device integrally or connected to the rotating handle.

[0159] The check valve 13 inside the pressure valve rotating body 17 is equipped with a positioning spring.

[0160] The high and low pressure device 1 can switch between high pressure function and low pressure function by rotating the valve rotating body.

[0161] The rotating device 21 on the suction valve rotating handle 23 of the high and low pressure pressure device 1 and the rotating device 21 on the pressure valve rotating handle 25 are integrally or connected to each other via the transmission device 24 and are formed as one unit.

[0162] The transmission device 24 is composed of gear transmission, belt transmission via pulley, chain transmission via sprocket, or shaft transmission. This embodiment uses pulley and transmission belt as an example.

[0163] The high and low pressure device 1 is integrally or connected to and formed as a whole with a moving device. The moving device is driven by a motor 5 or an engine to rotate the eccentric wheel 3 through a speed change mechanism, a belt pulley or a sprocket. The eccentric wheel 3 and the pressure rod 2 are integrally or connected to each other via a connecting rod shaft 20 and are arranged in a dynamic fit. The pressure body 7 and the pressure rod 2 are integrally or connected to each other and are arranged in a dynamic fit, and move back and forth along the pressure housing 6.

[0164] The high and low pressure pressurization device 1 is a gear pump, vane pump, or plunger pump; or the pressurization valve 15 and suction valve 11 are check valves, plunger valves, butterfly valves, or gate valves.

[0165] The valve is a check valve. The suction valve 11 is a directional air intake check valve, and the pressurizing valve 15 is a directional exhaust check valve, or a bidirectional check valve that changes the direction of fluid flow by rotating a rotating body in the valve cavity.

[0166] The pressure-regulating housing 6 of the high and low pressure device 1 is integrally or connected to and formed as a whole with a suction valve 11 and a pressurizing valve 15 on the outer periphery of its bottom. The suction valve 11 and the pressurizing valve 15 are integrally or connected to and formed as a whole by a rotating device via a transmission device 24. The rotating device of the suction valve 11 and the pressurizing valve 15 drives the rotating handle, and the rotation of the rotating handle drives the rotating body of the suction valve 11 and the pressurizing valve 15 to rotate and change the direction of fluid movement inside the pressure-regulating housing 6 and the outlet of the high and low pressure device 1, thereby forming a conversion of the high pressure or low pressure intake or output direction of the working air pressure chamber connected to the outside of the high and low pressure device 1.

[0167] like Figures 2-3 The high and low pressure device 1 shown is composed of multiple pressure-generating housings 6, which can continuously generate high-pressure gas or continuously pump gas.

[0168] The high and low pressure pressing device 1 is integrally or connected to form a single unit with multiple pressure-pressing housings 6; each pressure-pressing housing 6 is integrally or connected to form a single unit with a pressure-pressing body 7 that reciprocates axially along the inner wall of the pressure-pressing housing 6; each pressure-pressing body 7 is integrally or connected to form a single unit with a pressure-pressing rod 2 via a pressure-pressing body shaft 18 in a dynamic fit; each pressure-pressing rod 2 is integrally or connected to form a single unit with a dynamic fit with an eccentric wheel 3, or each eccentric wheel 3 is integrally or connected to form a single unit with a dynamic fit with two pressure-pressing rods 2; at least two eccentric wheels 3 are integrally or connected to form a single unit via a transmission shaft 19 and are disposed together with the motion device 4;

[0169] The bottom outer periphery of the pressure-controlling housing 6 is integrally or connected to form an integral arrangement with at least one or more pressure-increasing valves 15 and at least one or more suction valves 11; the pressure-increasing valves 15 or suction valves 11 of the pressure-controlling housing 6 of the high and low pressure-controlling device 1 are integrally or connected to a space chamber containing multiple external devices, namely a high-pressure space chamber or a low-pressure space chamber, via a high-low pressure control valve 59 and a pipeline 26.

[0170] The bottom outer periphery of the pressure-controlling housing 6 is integrally or connected to form an integral arrangement of at least one or more suction valves 11. The suction valves 11 of the pressure-controlling housing 6 of the high and low pressure-controlling device 1 are integrally or connected to the space chamber containing multiple external devices via the high and low pressure control valve 59 and the pipeline 26, thereby forming and creating multiple externally connected low-pressure spaces.

[0171] The bottom outer periphery of the pressure-regulating housing 6 is integrally or connected to form an integral part of the pressure-regulating valve 15; the pressure-regulating valve 15 of the pressure-regulating housing 6 of the high and low pressure-regulating device 1 is integrally or connected to the space chamber containing multiple external equipment via the high and low pressure control valve 59 and the pipeline 26, thereby forming and creating multiple externally connected high-pressure spaces.

[0172] The pressure regulating body 7 reciprocates within the pressure regulating shell 6, forming a pressure regulating body 7 at the top end that is far from the bottom end of the pressure regulating shell 6. This enlarges the space within the pressure regulating shell 6, increasing the space occupied by the gas and creating a low-pressure environment.

[0173] Alternatively, the pressure regulating body 7 may reciprocate within the pressure regulating housing 6, causing the pressure regulating body 7 to approach the bottom of the pressure regulating housing 6, thus reducing the space within the pressure regulating housing 6 and resulting in the ultimate compression of the gas within the pressure regulating housing 6 to form high pressure.

[0174] The airflow is directed by either enlarging the space within the pressure-bearing shell 6 to create low pressure or shrinking the space to create high pressure.

[0175] The high-low pressure compression device 1 is formed by an intake pressure valve 11 integrally connected to the external atmospheric environment and an exhaust pressure valve 15 integrally connected to form a working pressure chamber that forms a high-pressure and low-pressure compression device.

[0176] The pressure valve 15 at the exhaust end is integrally connected to the external atmospheric environment, and the suction valve 11 at the intake end is integrally connected to the working air pressure chamber to form a high-low pressure device 1 with low air pressure.

[0177] Alternatively, a three-way reversing valve (not shown) may be installed on the pipeline, which, in conjunction with the suction valve 11 and the pressurizing valve 15, adjusts the airflow direction.

[0178] The motion device includes a power system, including an electric motor or an engine.

[0179] The high and low pressure device 1 is composed of a moving device, a pressure rod 2, a pressure body 7, a pressure housing 6, and valves. The valves include a suction valve 11 and a pressurizing valve 15. By changing the direction of the suction valve 11 or the pressurizing valve 15, the high and low pressure of the working air chamber connected to the high and low pressure device 1 can be switched between high and low pressure. One end of the suction valve 11 or the pressurizing valve 15 of the high and low pressure device 1 is connected to the refrigerator, and the other end is connected to the external atmosphere.

[0180] like Figure 3 The high and low pressure device 1 shown is composed of two pressure housings 6 integrally or connected and formed as one unit, which can continuously generate high pressure gas or continuously draw in gas.

[0181] At least two pressure-controlling housings 6 are integrally or connected and formed as one unit, and at least two pressure-controlling bodies 7 are arranged in opposite directions of reciprocating motion along the inner bore of the pressure-controlling housing 6; each pressure-controlling body 7 is integrally or connected and formed as one unit in a dynamic fit with a pressure-controlling body shaft 18; at least two or more pressure-controlling rods 2 are integrally or connected and formed as one unit with at least one eccentric shaft 22 in a dynamic fit.

[0182] The power device drives the eccentric shaft 22 to rotate via the transmission device. The eccentric shaft 22 drives the pressure body 7 to reciprocate in opposite directions within the pressure housing 6 via two pressure rods 2.

[0183] The bottom outer periphery of the pressure-regulating housing 6 is integrally or connected to form an integral part of at least one or more suction valves 11 and at least one or more pressurizing valves 15.

[0184] The high-low pressure device 1, composed of a moving device, a pressure rod 2, a pressure body 7, a pressure housing 6, and valves including a suction valve 11 and a pressurizing valve 15, forms a highly efficient and high-speed high-low pressure device 1 that rapidly extracts or pressurizes gas. This device 1 has a simple structure, is lightweight, consumes little power, is highly efficient, and has a large pressure difference between high and low pressures. It effectively and quickly creates high or low pressure in the working chamber, making it widely applicable. It utilizes the pressure reduction effect to extract polluted gases and bacteria / mold into the atmosphere, which is beneficial for food preservation. It solves the problem of tedious cleaning of refrigerator cold storage compartments and the problem of clothing disposal. Pickling food under high pressure is quick and can effectively reduce the slowly generated toxic and harmful chemical components during the pickling process, effectively preventing threats to human health caused by food spoilage. Utilizing the effects of low-pressure recovery or extraction and high-pressure penetration or dissolution, it can be used to develop many household appliances, various experimental equipment, and other equipment requiring high or low pressure environments.

[0186] like Figures 4-9 , Figures 13-14 As shown, this embodiment discloses a safety door for a household appliance with high and low pressure functions. Since the household appliance in this embodiment adopts a method of creating a low-pressure or high-pressure environment, the low-pressure sterilization, decontamination, and high-pressure penetration functions are achieved by adding a high-low pressure pressurization device 1. This is energy-saving, environmentally friendly, and pollution-free. Under high and low pressure conditions, the casing of the household appliance has to withstand the effect of atmospheric pressure. The closed door cannot adapt to this and there is a danger. The household appliance is provided with a pressure-resistant casing 39, and the pressure-resistant casing 39 is provided with an internal groove 36. The pressure-resistant internal door 35 moves in the internal groove 36 to achieve the function of opening or closing, avoiding the hidden dangers of the appliance door breaking out under high pressure and the appliance door sinking inward under low pressure.

[0187] in Figures 4-9 This refers to an implementation method of installing a pressure-resistant safety door on the pressure-resistant casing 39 of household appliances such as refrigerators, variable-pressure washing machines, deodorizing and fragrance-adding machines, variable-pressure dishwashers, pickling machines, and foot care machines equipped with safety doors. Figure 13 This is a side view of a pressure-resistant safety door. Figure 14 This is a front view diagram of a pressure-resistant safety door;

[0188] The household appliance with high and low pressure functions includes a high and low pressure device 1. The high and low pressure device 1 is composed of a moving device, a pressure rod 2, a pressure body 7, a pressure housing 6, and valves. The valves include a suction valve 11 and a pressurizing valve 15. The high and low pressure device 1 manufactures all equipment that uses a high-pressure space chamber or a low-pressure space chamber.

[0189] The household appliance with high and low pressure functions is provided with a pressure-resistant housing 39. The high-pressure gas generated by the pressure valve 15 of the high and low pressure device 1 is controlled by the valve to form a high-pressure space chamber for the household appliance with high and low pressure functions.

[0190] Alternatively, the inner side of the pressure-resistant housing 39 may be formed by the suction valve 11 of the high and low pressure device 1, which generates low-pressure gas and controls the valve to form a low-pressure space chamber for household appliances with high and low pressure functions.

[0191] The inner side of the pressure-resistant housing 39 is integrally or integrally connected to form an internal groove 36, and the internal groove 36 is provided with a pressure-resistant sealing device 80 (i.e., a sealing gasket) and a pressure-resistant internal door 35.

[0192] An opening is integrally provided on the pressure-resistant housing 39 at one outer end of the built-in groove 36. A pressure-resistant built-in door 35 is provided in the built-in groove 36 through the pressure-resistant sealing device 80. The pressure-resistant built-in door 35 is completely pushed into the closed state in the built-in groove 36 through the groove-shaped opening. The high-pressure gas generated by the pressure valve 15 of the high and low pressure device 1 is controlled by the valve to form a high-pressure space chamber inside the pressure-resistant housing 39 of the household appliance with high and low pressure functions.

[0193] Alternatively, the low-pressure gas generated by the suction valve 11 of the high and low pressure device 1 can be controlled by a valve to form a low-pressure space chamber inside the pressure-resistant shell 39 of a household appliance with high and low pressure functions.

[0194] After the pressure-resistant built-in door 35 is drawn into the pressure-resistant housing 39 through the groove-shaped opening in the built-in groove 36 and the air pressure is balanced with the external atmospheric pressure, the pressure-resistant built-in door 35 continues to move outward along the groove-shaped opening in the built-in groove 36 until it is open, so that the items in the pressure-resistant housing 39, i.e., the high-pressure space chamber or the low-pressure space chamber, can be taken out.

[0195] The household appliance with high and low voltage functions is equipped with a pressure-resistant housing.

[0196] The high-pressure space chamber or low-pressure space chamber of the household appliance with high and low pressure functions is composed of a pressure-resistant shell 39.

[0197] The high-pressure space chamber or low-pressure space chamber of the household appliance with high and low pressure functions is composed of multiple pressure-resistant shells 39.

[0198] The pressure-resistant housing is integrally or integrally formed with at least one or more built-in grooves 36.

[0199] The pressure-resistant housing has at least one or more pressure-resistant sealing devices 80 installed in its built-in groove 36.

[0200] The pressure-resistant housing has at least one or more pressure-resistant sealing devices 80 and pressure-resistant built-in doors 35 in its built-in groove 36.

[0201] The pressure-resistant housing has at least one or more transparent observation windows 76 on its pressure-resistant internal door 35.

[0202] The pressure-resistant housing is provided with at least one or more slotted openings 78.

[0203] The pressure-resistant housing is provided with a handle 77 or a grooved handle 77.

[0204] The pressure-resistant housing has at least one or more pressure-resistant internal doors 35 in its slotted opening door frame.

[0205] The pressure-resistant housing has at least one or more pressure regulating grooves 79 on its built-in groove.

[0206] The pressure-resistant built-in door 35 is provided with an observation window; the built-in groove 36 is provided with a pressure regulating groove (not shown), and the outlet of the pressure regulating groove is located at the bottom of the household appliance with high and low voltage functions.

[0207] Implementation Method 3:

[0208] like Figures 1-3 , Figures 10-12As shown, this embodiment discloses the setting of a high and low pressure control valve 59 for a household appliance with high and low pressure functions. Based on embodiments one and two, this embodiment adds a high and low pressure control valve 59 to the pressure-generating device. Since the household appliance in this embodiment uses a high and low pressure device 1 to create a low pressure environment or a high pressure environment or a conversion between the two, it is very complicated and difficult to control using traditional valves, and accidents are easy to occur. In this embodiment, only the power device is needed to control the forward and reverse rotation of the valve handle 60 of the high and low pressure control valve 59 to create a high pressure environment or a low pressure environment. The high and low pressure device 1 is integrally or connected to and formed as an integral part of the high and low pressure control valve 59. The high and low pressure control valve 59 is composed of a valve shell 73, a valve body 66, and a valve cover 61.

[0209] The valve housing 73 is provided with a pressurization port 62 (A), a pressure reduction port 69 (B), an air extraction port 71 (D), an air filling port 68 (C), a circulation air inlet port 63 (E), and a circulation air outlet port 70 (F); the valve body 66 is provided with a three-way hole 64, a circulation air inlet port 74, a circulation air outlet port 75, and a sealing gasket 76.

[0210] The upper part of the valve body 66 is integrally or integrally connected to and formed with a valve handle 60. The valve handle 60 is driven to rotate by a transmission device. The valve body 66 is provided with a three-way hole 64. The three-way hole 64 forms a dynamic fit with the pressurization port 62 (A), the pressure reducing port 69 (B), and the exhaust port 69 (C) to close or open. The valve body 66 is provided with a circulation air inlet 74. The circulation air inlet 74 forms a dynamic fit with the pressurization port 62 (A), the pressure reducing port 69 (B), or the exhaust port 71 (D) and the air supply port 68 (C) through the circulation air inlet 63 (E) or the circulation air outlet 70 (F) to close or open.

[0211] The high and low pressure control valve has at least one or more three-way holes 64 on its valve body.

[0212] The high and low pressure control valve is provided with at least one or more circulating air inlet ports 74 and circulating air outlet ports 75 on its valve body.

[0213] The high and low pressure control valve is provided with at least one or more pressurization ports, circulation ports and air outlets on its valve body.

[0214] The high and low pressure control valve is provided with at least one or more pressure reducing ports, circulation ports and air inlets on its valve body.

[0215] The bottom of the valve body of the high and low pressure control valve is provided with a sealing cover.

[0216] The high and low pressure control valve has a lubrication hole at the bottom of its valve body, which is sealed by a screw.

[0217] The high / low pressure control valve 59 has a pressurization port 62(A) integrated with or connected to the outlet port (A') of the high / low pressure control device 1. The inner port of the pressurization port 62(A) is connected to the inner port of the gas inlet 68(C) via the G port on the valve body 66 and the K port of the three-way hole 64. The outer port of the gas inlet 68(C) is connected to the pressurization port of a household appliance with high / low pressure function. The high / low pressure control valve 59 has a pressure reduction port 69(B) integrated with or connected to the inlet port (B') of the high / low pressure control device 1. The inner port of the pressure reduction port 69(B) is connected to the inner end of the circulation inlet port 70(F) via the circulation inlet hole 74, allowing gas to be drawn in through the circulation inlet port 70(F). The high / low pressure control valve 59 has a pressure reduction port 69(B) integrated with... The air inlet (B') of the high and low pressure compression device 1 is integrally or connected and formed as one unit. The air extraction port 71 (D) of the high and low pressure control valve 59 is connected to the pressure reducing port of the household appliance with high and low pressure function. At this time, the inner port of the air extraction port 71 (D) is not connected to the H port of the three-way hole 64 and is in a closed state. The high pressure gas of the high and low pressure compression device 1 enters the pressure port 62 (A) of the high and low pressure control valve 59 through the air outlet (A') provided on the pressure valve 15. It is connected to the inner port of the air inlet 68 (C) through the K port of the three-way hole 64. The outer port of the air inlet 68 (C) is connected to the pressure port of the household appliance with high and low pressure function to form a high pressure environment in the pressure-resistant housing 39 of the household appliance. The exhaust port 71 (D) of the pressure reducing port of the household appliance is in a closed state with the three-way hole 64.

[0218] The valve handle 60 of the high and low pressure control valve 59 is rotated by the transmission device until the G port on the three-way hole 64 of the valve body 66 is connected to the inner port of the pressure reducing port 69 (B) of the high and low pressure control valve 59. The H port of the three-way hole 64 is connected to the inner port of the exhaust port 71 (D). The inner port of the pressurizing port 62 (A) is connected to the inner end of the F port of the high and low pressure control valve 59 through the circulation exhaust hole 75 on the valve body 66. The inner port of the pressurizing port 62 (A) is connected to the inner end of the F port of the high and low pressure control valve 59 through the circulation exhaust hole 75. The gas is discharged from the recirculating exhaust port (E) 63 by connecting to the inner port of the recirculating exhaust port (E) 63. The interior of the gas inlet 68 (C) port of the high and low pressure control valve 59 is not connected to the K port of the three-way hole 64 and is in a closed state. The outer port of the exhaust port 71 (D) is connected to the pressure reducing port of the household appliance with high and low pressure functions to extract the gas inside the household appliance. A low pressure environment is formed in the pressure-resistant housing 39. The pressure-reducing port 68 (C) of the household appliance and the three-way hole 64 are in a closed state.

[0219] As described above, by changing the connection method of the high and low pressure control valve 59, the positions of the circulating air inlet 74 and the circulating air outlet 75 are lowered to the suction port 71 (D), and the heights of the air inlet 68 (C), the circulating air inlet (E) 63, and the circulating air outlet 70 (F) are respectively matched. For example, the suction port 71 (D) of the high and low pressure control valve 59 is integrated or connected to the exhaust port (A') of the high and low pressure compression device 1 and is formed as one unit. Or the air inlet 68 (C) of the high and low pressure control valve 59 is integrated or connected to the air inlet (B') of the high and low pressure compression device 1 and is formed as one unit. The inner port of the pressure reducing port 69 (B) is connected to the circulating air inlet 70 (F) through the circulating air inlet 74. As described above, this also serves to control the high or low pressure environment of household appliances.

[0220] The high and low pressure control valve 59 described above is a dual-flow-channel switching control valve.

[0221] According to the above structure, since the high and low pressure device 1 is used in the household appliance to create a high or low pressure environment, it is necessary to adjust the air pressure in the storage compartment of the household appliance to balance the atmospheric pressure whenever items are taken out or put in. Therefore, it needs to be adjusted constantly. Traditional valve adjustment is complicated and difficult to safely achieve air pressure adjustment. This embodiment can effectively and quickly achieve the cyclic conversion of high pressure, low pressure or normal pressure, ensuring the implementation of the effect of high and low pressure household appliances.

[0222] Implementation Method Four:

[0223] like Figures 1-4 , Figures 10-12 As shown, based on embodiments one through three, this embodiment employs a method of creating a high-pressure or low-pressure circulating freezing process for food by establishing a high-pressure or low-pressure environment under low-temperature conditions in the cold storage or refrigerator compartment of a refrigerator-type refrigeration unit. This embodiment adds a high-low pressure compression device 1 to the refrigeration equipment. Figure 4 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figure 2 It is a high and low pressure device 1 with two pressure-controlling housings 6; the following is in conjunction with Figure 1 This implementation method is described below;

[0224] This embodiment is a way of implementing the technologies of high and low pressure device 1, high and low pressure control valve 59, and pressure-resistant built-in door 35 in a refrigerator.

[0225] The refrigerator of this embodiment includes a pressure-resistant shell 39, an internal groove 36, a pressure-resistant sealing device 80, a pressure regulating valve 37, a pressure-resistant internal door 35, an observation window 38, a dryer filter 28, a capillary tube 29, a refrigeration system 30, a refrigerator shell 31, a safety valve 32 (limiting the maximum and minimum air pressure), a pressure-resistant inner shell 33, a low-pressure-resistant upper door, a freezer compartment or refrigerator compartment (i.e., a cold storage compartment), a refrigeration system 30, a high-pressure-resistant lower door, a pressure-resistant door, and a high / low pressure control device 1. The high / low pressure control device 1 is composed of a moving device, a pressure-controlling rod 2, a pressure-controlling body 7, a pressure-controlling shell 6, and valves, including a suction valve 11 and a pressurizing valve 15. The high / low pressure control device 1 manufactures all equipment using high-pressure or low-pressure spaces.

[0226] In the second embodiment, the two pressure-bearing housings 6 are integrally formed or connected and arranged side by side as an integral unit:

[0227] The cold storage compartments of various refrigeration equipment such as refrigerators are cold storage compartments or cold storage compartments that are in a high-pressure and low-temperature environment higher than the atmospheric environment or a low-pressure and low-temperature environment lower than the atmospheric environment, and process, pickle and preserve food by means of high-pressure permeation or low-pressure decomposition.

[0228] The various refrigeration equipment such as refrigerators are integrally or connected to form an integral connection with a high and low pressure device 1; the high and low pressure device 1 is integrally or connected to form an integral connection with a pressure valve 15 that generates pressure higher than atmospheric pressure and pressure valve 15 that generates pressure lower than atmospheric pressure.

[0229] The pressurizing valve 15, which is integrally or connected to and formed as an integral part of the high and low pressure pressurizing device 1, increases the gas in the cold storage chamber, forming a high-pressure cold storage chamber with a gas pressure higher than that of the external atmospheric environment.

[0230] The refrigerator is equipped with a high-pressure anti-opening safety door, the safety door is equipped with a manual safety valve 32, and the refrigerator safety door is equipped with a high-pressure locking device.

[0231] The high-pressure locking device is locked by the positioning pin being pushed out by the high pressure inside, and unlocked by the spring pushing out the positioning pin under normal pressure.

[0232] The high and low pressure pressing device 1 is integrally or connected to form an integral part of at least two parallel pressing housings 6; each pressing housing 6 is integrally or connected to form an integral part of a pressing body 7 that reciprocates axially along the inner wall of the pressing housing 6; each pressing body 7 is integrally or connected to form an integral part of a pressing rod 2 that is dynamically fitted via a pressing body shaft 18; the other end of each pressing rod 2 is integrally or connected to form an integral part of an eccentric wheel 3 that is dynamically fitted; at least two eccentric wheels 3 are integrally or connected to form an integral part of the device and are integrally or connected to form an integral part of the transmission device 4.

[0233] The pressure regulating body 7 reciprocates along the hole wall axially inside the pressure regulating housing 6 until the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is the largest and the gas is the most abundant. At this time, the pressure regulating body 7 compresses the space of the internal gas to form a high pressure. Alternatively, when the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is the smallest and the gas is the least abundant, the pressure regulating body 7 expands the space of the internal gas to form a low pressure.

[0234] Each pressure-controlling housing 6 of the high and low pressure-controlling device 1 is integrally or connected and formed as one on the bottom outer periphery of a pressure-increasing valve 15 that generates pressure higher than atmospheric pressure and a pressure-absorbing valve 11 that generates pressure lower than atmospheric pressure.

[0235] The suction valve 11 and the pressurizing valve 15 installed on the pressure-controlling housing 6 of the high and low pressure-controlling device 1 are connected to the outside of the pressure-controlling housing 6.

[0236] Alternatively, the refrigerator may be configured with a low-pressure cold storage compartment, which is combined with a high-pressure cold storage compartment.

[0237] In the second embodiment, the two pressure-bearing shells 6 are integrally formed or connected and arranged in a front-to-back configuration:

[0238] The high and low pressure device 1 has two pressure-controlling housings 6 that are integrally arranged or connected and formed as one unit and are arranged in front and behind each other.

[0239] Each pressure-controlling housing 6 has a pressure-controlling body 7 that reciprocates axially along the inner wall of the pressure-controlling housing 6 on its inner side; each pressure-controlling body 7 is integrally or connected to form an integral dynamic fit with a pressure-controlling body shaft 18; the other ends of the two pressure-controlling rods 2 are integrally or connected to form an integral dynamic fit with the transmission device 4.

[0240] The pressure regulating body 7 reciprocates along the hole wall axially inside the pressure regulating housing 6 until the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is the largest and the gas is the most abundant. At this time, the pressure regulating body 7 compresses the space of the internal gas to form a high pressure. Alternatively, when the space between the pressure regulating body 7 and the bottom cover of the pressure regulating housing 6 is the smallest and the gas is the least abundant, the pressure regulating body 7 expands the space of the internal gas to form a low pressure.

[0241] Each pressure-generating housing 6 of the high and low pressure-generating device 1 is integrally or connected and formed as one on the bottom outer periphery of a pressure-generating valve 15 that generates pressure higher than atmospheric pressure and a pressure-absorbing valve 11 that generates pressure lower than atmospheric pressure.

[0242] The valve is a check valve. The suction valve 11 is a directional air intake check valve, and the pressurizing valve 15 is a directional exhaust check valve, or a bidirectional check valve that changes the direction of fluid flow by rotating a rotating body in the valve cavity.

[0243] The pressure-regulating housing 6 of the high and low pressure device 1 is integrally or connected to form an integral part of the bottom outer periphery of the pressure-regulating valve 11 and the pressure-increasing valve 15. The pressure-regulating valve 11 and the pressure-increasing valve 15 are integrally or connected to form an integral part of the device by a rotating device and a transmission device 24. The rotating device of the pressure-regulating valve 11 and the pressure-increasing valve 15 drives the rotating handle. The rotation of the rotating handle drives the rotating body of the pressure-regulating valve 11 and the pressure-increasing valve 15 to rotate and change the direction of fluid movement inside the pressure-regulating housing 6 and the outlet of the high and low pressure device 1, thereby changing the direction of high pressure or low pressure intake or output of the working air pressure chamber connected to the outside of the high and low pressure device 1.

[0244] The pressure valves 15 of the two pressure-controlling housings 6 are integrally or connected to each other via pipes 26 and are formed as one unit.

[0245] The suction valves 11 of the two pressure-controlling housings 6 are integrally or connected to each other via pipes 26 and valves, and are formed as one unit.

[0246] Two or more pressure-regulating housings 6 can be integrally or connected and formed as one unit to form a continuous low pressure or a continuous high pressure.

[0247] Alternatively, a three-way reversing valve (not shown) may be installed on the pipeline, which, in conjunction with the suction valve 11 and the pressurizing valve 15, adjusts the airflow direction.

[0248] The refrigerator is equipped with a safety valve 32, which regulates the high and low air pressure of the cold storage compartment through the exhaust port for safety.

[0249] When refrigerating or freezing food, the high and low pressure device 1 first extracts the polluted gas and discharges it into the outside atmosphere. After the valve of the high and low pressure device 1 is automatically closed, the cold storage compartment is in a low pressure or vacuum state. The safety valve 32 equalizes the internal air pressure with the external air pressure, and the refrigerator completes the purification process.

[0250] When quickly marinating food, the food is first prepared and placed in a cold storage chamber. The high and low pressure device 1 extracts the polluted gas from the cold storage chamber and releases it into the outside atmosphere. After the valve of the high and low pressure device 1 is automatically closed, the cold storage chamber is in a low pressure or vacuum state. The safety valve 32 equalizes the internal air pressure with the external air pressure. Then, the high and low pressure device 1 pressurizes the cold storage chamber. After the pressure is maintained for a certain time, the safety valve 32 equalizes the internal air pressure with the external air pressure, and the marinated food can be taken out. By marinating or seasoning quickly at low temperature, food spoilage can be prevented and nutrient loss can be avoided.

[0251] The refrigerator described above is based on the refrigeration system 30 and adds a high-low pressure cyclical environment to create a refrigerator that uses a high-low pressure pressurization device 1 and a safety valve 32 to create low pressure for deodorization and preservation, and uses a high-low pressure pressurization device 1 to create high pressure for flavoring and preservation.

[0252] The refrigerator exhausts or reduces the gas inside the refrigerator through the exhaust port, high and low pressure device 1, suction valve and pipe; the refrigerator increases the gas pressure inside the refrigerator through the high and low pressure device 1, pressure valve and pipe.

[0253] The refrigerator is equipped with a safety valve 32, which regulates the high and low air pressure of the freezer or storage compartment of the cold storage compartment through the exhaust port.

[0254] Because it employs two high-low pressure compression devices 1 combined or integrated, connected by pipelines to form a continuous high-pressure or low-pressure high-efficiency manufacturing system, the high-low pressure compression device 1 is composed of a moving device 4, a pressure-controlling rod 2, a pressure-controlling body 7, a pressure-controlling shell 6, and valves, including a suction valve 11 and a pressurizing valve 15. This forms a highly efficient, high-speed high-low pressure compression device 1 for rapidly pumping out or pressurizing gas. This high-low pressure compression device 1 has a simple structure, is lightweight, has low power consumption, high efficiency, and a large high-low pressure difference, effectively and quickly creating a high-pressure or low-pressure working chamber. High pressure has a wide range of applications. By utilizing the decompression effect, polluted gases, germs, and molds are extracted into the atmosphere, which is beneficial for food preservation. It solves the problem of the troublesome cleaning of refrigerator cold storage compartments or the problem of clothing disposal. Pickling food under high pressure is quick and can effectively reduce the toxic and harmful chemical components that are slowly generated during the pickling process, effectively preventing the threat to people's health caused by food spoilage. By utilizing the effects of low pressure recovery or extraction and high pressure penetration or dissolution, many household appliances, various experimental equipment, and other equipment that require high or low pressure environments can be developed.

[0257] This embodiment employs a method of circulating freezing of food in a cold storage chamber under low-temperature conditions, creating environments of low pressure, normal pressure, and high pressure. Figure 4 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figure 2 , Figure 3 It is a high and low pressure device 1 with two pressure-controlling housings 6; the following is in conjunction with Figures 2-3 , Figure 4 This embodiment is described.

[0259] The high and low pressure pressing device 1 is integrally or connected to form a single unit with multiple pressure-pressing housings 6; each pressure-pressing housing 6 is integrally or connected to form a single unit with a pressure-pressing body 7 that reciprocates axially along the inner wall of the pressure-pressing housing 6; each pressure-pressing body 7 is integrally or connected to form a single unit with a pressure-pressing rod 2 via a pressure-pressing body shaft 18 in a dynamic fit; each pressure-pressing rod 2 is integrally or connected to form a single unit with a dynamic fit with an eccentric wheel 3, or each eccentric wheel 3 is integrally or connected to form a single unit with two pressure-pressing rods 2 in a dynamic fit; at least two eccentric wheels 3 are integrally or connected to form a single unit together and integrally or connected to form a single unit together with the motion device 4;

[0261] The high and low pressure pressing device 1 is integrally or connected to and formed as a whole with a pressure-pressing housing 6; the inner side of the pressure-pressing housing 6 is provided with a pressure-pressing body 7 that reciprocates axially along the inner wall of the pressure-pressing housing 6; the pressure-pressing body 7 is integrally or connected to and formed as a whole with a pressure-pressing rod 2 in a dynamic fit.

[0263] The bottom outer periphery of the pressure-regulating housing 6 is integrally or connected and integrally formed with a pressure-increasing valve 15 that generates pressure higher than the atmospheric environment and a pressure-absorbing valve 11 that generates pressure lower than the atmospheric environment.

[0264] When the pressure regulating body 7 reciprocates axially along the hole wall inside the pressure regulating housing 6, forming a situation where the gas inside the pressure regulating housing 6 is at its maximum, the pressure regulating body 7 compresses the high gas pressure in the internal space; when the pressure regulating body 7 reciprocates axially along the hole wall inside the pressure regulating housing 6, forming a situation where the gas inside the pressure regulating housing 6 is at its minimum, the pressure regulating body 7 expands the low gas pressure in the internal space.

[0265] The pressure-regulating housing 6 has a suction valve 11 or a pressurizing valve 15 integrally or integrally connected to the outer periphery of the bottom end, and is connected to the space chamber of the equipment outside the pressure-regulating housing 6 via a high and low pressure control valve 59 and a pipe 26, respectively.

The bottom outer periphery of the pressure-controlling housing 6 is integrally or connected to form a plurality of pressure-controlling housings 6. The pressure-controlling housing 6 of the high and low pressure pressurization device 1 is integrally or connected to form a plurality of pressure-controlling housings 6. The pressure-controlling housing 6 of the high and low pressure pressurization device 1 is connected to the space chamber of external equipment, namely the refrigerator or freezer, through the high and low pressure control valve 59 and the pipe 26, thereby forming and creating a plurality of externally connected low-pressure space or high-pressure space.

[0267] The vibratory feeder can be configured as a mesh, fence, basket, cylinder or box, which will not be described in detail here.

[0268] Based on the above structure, the cold storage compartment inside the refrigerator's pressure-resistant shell 39 ensures safety. By using a low-pressure, gaseous, or fluid environment to remove mold and odors, manual scrubbing and sterilization are unnecessary, avoiding chemical contamination from existing chemical detergents. Through pressure changes in high-pressure, normal-pressure, normal-pressure, low-pressure, or high-pressure, low-pressure environments, not only are mold and odors expelled, but bacteria or other harmful components adhering to food are also effectively removed. High-pressure pickling can also shorten the pickling time, avoid nutrient loss, and is very convenient, improving efficiency and preventing food spoilage from harming people's health.

[0269] The refrigerator's pressure-resistant shell 39 can be equipped with a spice bottle or medicine bottle, which is connected to the cold storage compartment via valves and pipes.

[0270] Although the above description uses a refrigerator as an example, the refrigerator of the present invention can also be implemented using some of the technical methods. The low-pressure or vacuum sterilization food preservation method of the present invention can also have more structural forms. The structure described above can be a combination of the structure described in the embodiment and other forms.

This variable pressure washing machine is energy-saving, environmentally friendly, and pollution-free. A high-low pressure device 1 is added to the variable pressure washing machine of this embodiment. Figure 1 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figures 2-3 It consists of two pressure-bearing housings 6 arranged side by side and front and rear opposite each other, forming a high and low pressure device 1. The following is in conjunction with... Figures 1-3 , Figure 5 , Figures 10-12 This implementation method is described below;

[0273] This embodiment is an embodiment in which a high-pressure space chamber or a low-pressure space chamber is formed by a high-low pressure device 1, a high-low pressure control valve 59, and a pressure-resistant built-in door 35 on the pressure-resistant housing 39 inside the pressure-resistant housing 39.

The washing chamber 47 is equipped with a water inlet valve 32, a drain valve 45, an exhaust valve 33, and a safety valve 46. The variable pressure washing machine shell is equipped with a high and low pressure device 1, which is composed of a motion device, a pressure rod 2, a pressure body 7, a pressure shell 6, and valves. The valves include a suction valve 11 and a pressurizing valve 15. The high and low pressure device 1 manufactures all equipment that uses a high-pressure space or a low-pressure space.

[0275] Figure 4 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figures 5-6 It is a high and low pressure device 1 with two pressure-controlling housings 6; the following is in conjunction with Figures 4-6 This implementation method is described below;

[0276] Under normal pressure, clothes are immersed in volatile detergent 45 in the washing chamber 47 of the variable pressure washing machine. The clothes and detergent are vibrated by a vibration device 48 installed in the washing chamber 47 at a certain frequency. The fluid formed by the detergent 45 impacts the clothes, avoiding friction between the clothes and between the clothes and the washing machine. The detergent directly washes away stains and grease. After the vibration washing is completed, the clothes are discharged from the washing chamber 47. The suction valve on the high and low pressure device is connected to the washing chamber 47 through the high and low pressure control valve 59 and the pipeline, and the exhaust gas in the washing chamber 47 is discharged. After low-pressure purification treatment, the washing is completed at normal pressure.

[0277] Alternatively, the variable pressure washing machine washes clothes in a low-pressure environment (lower than atmospheric pressure) in the washing chamber 47 to enhance the decomposition and removal of stains and grease from the clothes. Under low pressure, the clothes are initially removed by the vibration device 48. The pressure-resistant housing 39 is equipped with a safety valve 46 to prevent high pressure limits or low pressure limits.

[0278] Alternatively, under low pressure, the clothes are initially removed from the dirt and grease by the vibration device 48. In the washing chamber 47 of the variable pressure washing machine, the clothes are immersed in water-soluble detergent. The vibration device 48 installed in the washing chamber 47 of the variable pressure washing machine vibrates the clothes and detergent, forming an impact of detergent on the clothes to avoid friction between the clothes and between the clothes and the washing machine. The detergent directly washes away the dirt and grease. After vibration, the detergent is discharged out of the washing chamber 47. After rinsing, the rinsing liquid is discharged. The variable pressure washing machine is integrally or connected to form an integral connection with a high and low pressure device. The high and low pressure device can generate a low air pressure lower than the atmospheric air pressure. The pressure-generating housing of the high and low pressure device is integrally or connected to form an integral connection with a pressure valve that generates a pressure higher than the atmospheric air pressure and a suction valve that generates a pressure lower than the atmospheric air pressure.

[0279] The variable pressure washing machine uses a suction valve integrally connected to or formed as an integral part of the washing chamber 47 via a high and low pressure control valve 59 and a pipeline to discharge gas or fluid from the washing chamber 47, forming a low-pressure washing chamber 47 where the air pressure in the washing chamber 47 is lower than the external atmospheric pressure.

[0280] The washing chamber 47 of the variable pressure washing machine is driven by the motor 5 and rotated through the transmission device 4 and the power output shaft 49.

[0281] Alternatively, the laundry room 47 may be placed in the laundry cage 43.

[0282] Alternatively, a three-way reversing valve (not shown) may be installed on the pipeline, which, in conjunction with the suction valve 11 and the pressurizing valve 15, adjusts the airflow direction.

[0283] The high and low pressure pressing device 1 is integrally or connected to and formed as a single unit with a pressure-pressing housing 6; a pressure-pressing body 7 is provided on the inner side of the pressure-pressing housing 6, which reciprocates axially along the inner wall of the pressure-pressing housing 6; a pressure-pressing rod 2 is integrally or connected to and formed as a single unit via a pressure-pressing body shaft 18 in a dynamic fit; the other end of the pressure-pressing rod 2 is integrally or connected to and formed as a single unit in a dynamic fit with the transmission device 4;

[0284] The pressure regulating body 7 reciprocates axially along the hole wall inside the pressure regulating housing 6 until the space between the pressure regulating body 7 and the bottom of the pressure regulating housing 6 is at its maximum and the amount of gas or fluid is at its maximum. In this case, the pressure regulating body 7 compresses the space of gas or fluid inside the pressure regulating housing 6 to form a high pressure. Alternatively, when the space between the pressure regulating body 7 and the bottom of the pressure regulating housing 6 is at its minimum and the amount of gas or fluid is at its minimum, the pressure regulating body 7 expands the space of gas or fluid inside the pressure regulating housing 6 to form a low pressure. A sealing ring 8 is provided on the pressure regulating body 7.

[0285] The pressure-generating housing 6 of the high and low pressure device 1 is integrally or connected to and formed as a single unit at the bottom outer periphery of a pressure-generating valve 15 that generates pressure higher than the atmospheric environment and a pressure-absorbing valve 11 that generates pressure lower than the atmospheric environment.

[0286] The suction valve 11 has a suction valve rotating body 9 integrally or connected to it in a dynamically fitted manner within its cavity 10. A check valve 13 is installed inside the suction valve rotating body 9. The suction valve rotating body 9 is integrally or connected to it in a dynamically fitted manner within the cavity 10 of the suction valve 11. The pressurizing valve cavity 16 has a pressurizing valve rotating body 17 integrally or connected to it in a dynamically fitted manner within its cavity 16. A check valve 13 is installed inside the pressurizing valve rotating body 17. A valve shaft 12 is installed on the check valve 13. A spring 14 is installed between the check valve 13 and the suction valve rotating body 9. A spring 14 is installed between the check valve and the pressurizing valve rotating body 17. The pressurizing valve rotating body 17 is integrally or connected to it in a dynamically fitted manner within the pressurizing valve cavity 16.

[0287] The rotating body has a rotating handle integrally or connected to the top end and is integrally provided with a rotating device integrally or connected to the rotating handle.

[0288] The high and low pressure control device 1 can switch between high pressure and low pressure functions by rotating the valve handle 60 of the high and low pressure control valve 59.

[0289] The transmission device 24 is composed of gear transmission, belt transmission via pulley, chain transmission via sprocket, or shaft transmission. This embodiment uses pulley and transmission belt as an example.

[0290] The high and low pressure device 1 is integrally or connected to and formed as a whole with a moving device. The moving device is driven by a motor 5 or an engine to rotate the eccentric wheel 3 through a speed change mechanism, a belt pulley or a sprocket. The eccentric wheel 3 and the pressure rod 2 are integrally or connected to each other via a connecting rod shaft 20 and are arranged in a dynamic fit. The pressure body 7 and the pressure rod 2 are integrally or connected to each other and are arranged in a dynamic fit, and reciprocate along the pressure housing 6.

[0291] The bottom outer periphery of the pressure-controlling housing 6 is integrally or connected to and integrally formed with at least one or more suction valves 11. The suction valves 11 of the pressure-controlling housing 6 of the high and low pressure-controlling device 1 are integrally or connected to the space inside the multiple washing machine tubs 43 via the high and low pressure control valve 59 and the pipe 26, thereby forming and creating a low-pressure space inside the washing machine tubs 43.

[0292] The bottom outer periphery of the pressure-regulating housing 6 is integrally or connected to form an integral part of the pressure valve 15; the pressure valve 15, high and low pressure control valve 59 and pipe 26 of the pressure-regulating housing 6 of the high and low pressure device 1 are integrally or connected to form an integral part of the space inside the multiple washing machine tubs 43, forming and creating a high-pressure space inside the washing machine tubs 43.

[0293] The pressure regulating body 7 reciprocates within the pressure regulating housing 6, forming a pressure regulating body 7 at the top end of the pressure regulating housing 6 that is far from the bottom end of the pressure regulating housing 6. This enlarges the space within the pressure regulating housing 6, increasing the space occupied by the gas or fluid within the pressure regulating housing 6 and forming a low-pressure high-low pressure regulating device 1.

[0294] Alternatively, the pressure regulating body 7 may reciprocate within the pressure regulating housing 6 to form a pressure regulating housing 6 near the bottom end of the pressure regulating housing 6, thereby reducing the space within the pressure regulating housing 6 and compressing the gas or fluid within the pressure regulating housing 6 to form a high-pressure high-low pressure device 1.

[0295] The airflow is directed by either enlarging the space within the pressure-bearing shell 6 to create low pressure or shrinking the space to create high pressure.

[0296] The high-low pressure compression device 1 is formed by an intake pressure valve 11 integrally connected to the external atmospheric environment and an exhaust pressure valve 15 integrally connected to form a working pressure chamber that forms a high-pressure and low-pressure compression device.

[0297] The pressure valve 15 at the exhaust end is integrally connected to the external atmospheric environment, and the suction valve 11 at the intake end is integrally connected to the working air pressure chamber to form a high-low pressure device 1 with low air pressure.

[0298] The motion device includes a transmission system and a power system. The transmission system includes belt drive, gear drive, or shaft drive, and the power system includes an electric motor or an engine.

[0299] The high-low pressure device 1, composed of a moving device, a pressure rod 2, a pressure body 7, a pressure housing 6, and valves including a suction valve 11 and a pressurizing valve 15, forms a highly efficient and high-speed high-low pressure device 1 that can quickly pump out or pressurize gas or fluid. This high-low pressure device 1 has a simple structure, is lightweight, consumes little power, is highly efficient, and has a large pressure difference between high and low pressure. It can effectively and quickly create a high or low pressure working chamber, has a wide range of applications, and utilizes the pressure reduction effect to pump out polluted gas or fluid and pathogens and molds into the atmosphere.

[0300] Implementation Method Seven:

[0301] like Figures 2-3 , Figure 5 , Figures 10-12As shown, based on embodiments one through six, this embodiment is an embodiment in which a high-pressure space chamber or a low-pressure space chamber is formed by a high-low pressure device 1, a high-low pressure control valve 59, and a pressure-resistant internal door 35 on the pressure-resistant housing 39 of the variable pressure washing machine.

[0302] Based on embodiments one and two, the variable pressure washing machine of this embodiment uses a low-pressure environment (lower than atmospheric pressure) in the washing chamber 47 to enhance the decomposition and removal of stains and grease on clothes, and a high-pressure environment (higher than atmospheric pressure) to enhance the dissolution of detergent and penetration of stains and grease on clothes. This washing machine uses a cycle of low pressure, normal pressure, and high pressure to wash clothes. A high-low pressure device 1 is added to the variable pressure washing machine of this embodiment. Figure 1 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figure 2 It is equipped with two pressure-bearing housings 6 arranged side by side and front and rear opposite to a high and low pressure device 1, combined with Figures 1-3 , Figures 4-6 This embodiment will be described in a brief description of embodiments one through six;

[0303] The variable pressure washing machine of this embodiment includes a shell, a pressure-resistant inner door 35, a vibration device 48, a washing chamber 47, a water inlet valve 32, a drain valve 45, and a vent valve. The shell of the variable pressure washing machine is provided with a high and low pressure device, which is composed of a motion device, a transmission device, a pressure rod 2, a pressure body, a pressure shell, and valves. The valves include a suction valve and a pressurizing valve.

[0304] Figure 4 It is equipped with a high and low pressure device 1 with a pressure-controlling housing 6. Figure 3 It is a high and low pressure device 1 consisting of two pressure-bearing housings 6 set together; the following is in conjunction with Figures 1-2 , Figure 5 , Figures 10-12 This embodiment will be briefly described in conjunction with the brief descriptions of embodiments one through six;

[0305] In Embodiment 3, multiple pressure-bearing housings 6 are integrally or connected and formed as a single unit:

[0306] The variable pressure washing machine uses a low-pressure environment in the washing chamber 47, which is lower than the atmospheric pressure, to enhance the decomposition and removal of stains and grease on the clothes, and uses a high-pressure environment in the washing chamber 47, which is higher than the atmospheric pressure, to enhance the dissolution and penetration of stains and grease on the clothes.

[0307] The high and low pressure compression device 1 is integrally or connected to form a single unit with multiple pressure-controlling housings 6; each pressure-controlling housing 6 is integrally or connected to form a single unit with a pressure-controlling body 7 that reciprocates axially along the inner wall of the pressure-controlling housing 6; each pressure-controlling body 7 is integrally or connected to form a single unit with two pressure-controlling rods 2 via a pressure-controlling body shaft 18 in a dynamic fit; at least one or more pressure-increasing valves 15 and at least one or more suction valves 11 are integrally or connected to form a single unit on the outer periphery of the bottom of the pressure-controlling housing 6; the pressure-increasing valves 15 and suction valves 11 of the pressure-controlling housing 6 of the high and low pressure compression device 1 are integrally or connected to form a single unit with a space containing multiple external devices via a high and low pressure control valve 59 and a pipe 26.

[0308] The high and low pressure device 1 is integrally or connected to form a single unit with two pressure-controlling housings 6; the inner side of each pressure-controlling housing 6 is provided with two pressure-controlling bodies 7 that reciprocate axially along the inner wall of the pressure-controlling housing 6; each pressure-controlling body 7 is integrally or connected to form a single unit with a pressure-controlling rod 2 in a dynamic fit; the two pressure-controlling rods 2 are integrally or connected to form a single unit with an eccentric shaft 22 in a dynamic fit; the eccentric shaft 22 is integrally or connected to the motor 5 via a transmission device and is formed as a single unit.

[0309] The pressure regulating body 7 reciprocates along the axial direction of the hole wall inside the pressure regulating housing 6 to form a high pressure for ultimate compression when the internal gas or fluid space is extremely large, or a low pressure for ultimate expansion when the gas or fluid space is extremely small; the bottom outer periphery of the pressure regulating housing 6 is integrally or integrally connected to form a pressure suction valve 11 or a pressure valve 15, and is connected to the equipment space outside the pressure regulating housing 6 through a high and low pressure control valve 59 and a pipe 26 respectively;

[0310] The suction valve 11 and the pressurization valve 15 are respectively connected to the equipment space outside the pressure-controlling housing 6 via the high and low pressure control valve 59 and the pipeline 26 to form a cycle of high pressure, normal pressure and low pressure.

[0311] Based on the above structure, washing clothes in low-pressure, normal-pressure, or high-pressure environments reduces or eliminates water consumption, requires little or no water as a carrier, reduces water waste, reduces the amount of detergent used, and improves efficiency.

[0312] In winter, the clothes can be heated by the suction valve after washing using a temperature control device, and then they can be taken out and worn.

[0313] As can be seen from the above structure, the variable pressure washing machine can at least use a pulsator washing machine tub or a drum washing machine tub. A fragrance bottle or a fiber repair liquid bottle can be installed on the casing of the variable pressure washing machine, which is connected to the pressure-resistant casing 39 via valves and pipes. A temperature control device can also be installed on the pressure-resistant casing 39 of the variable pressure washing machine to maintain a certain temperature for clothes after washing in winter. A microcomputer and keyboard 49 device can also be installed on the variable pressure washing machine to realize intelligent washing.

[0314] According to the above structure, the pressure-resistant shell 39 is installed inside the casing 40 of the variable pressure washing machine, ensuring safety. Since stains are removed using high-pressure, low-pressure, or vacuum environments, vigorous rubbing is unnecessary, reducing mechanical damage to clothes. The method of using detergent or washing gas to decompose and vaporize stains avoids the chemical damage to clothes caused by chemical detergents used in existing variable pressure washing machines. Through at least one high-pressure or low-pressure environment and at least one gas or fluid discharge, not only are stains removed, but bacteria or other harmful components adhering to the clothes are also effectively removed. This washing method eliminates the need for drying clothes; they can be worn immediately after washing, which is very convenient, extends the lifespan of clothes, greatly reduces power consumption, and eliminates environmental pollution.

[0315] Based on the above structure, since washing clothes in high-pressure, low-pressure, or vacuum environments requires almost no water or very little water as a carrier, water waste is reduced. The washing gas can be carbon dioxide or a special volatile detergent, or industrial waste gas can be effectively utilized, thus improving waste utilization rate.

[0316] The high and low pressure technologies and vibration technologies involved in the variable pressure washing machines are configured on different washing machines. They can achieve the goal of washing clothes by simply changing the air pressure or enhancing the washing function by changing the air pressure, thereby reducing or eliminating environmental pollution.

[0319] The deodorizing and fragrance-adding machine uses a high-pressure environment (higher than atmospheric pressure) inside the pressure-resistant housing 39 to enhance the deodorizing agent's penetration and dissolution of stains and grease on clothing. After exhausting the exhaust gas at normal pressure, fragrances or medicines are added, and then the fragrances or medicines are powerfully sprayed into the clothing under high pressure to clean the clothes.

[0320] The deodorizing and fragrance-adding machine is equipped with a pressure-resistant housing 39, which includes an internal groove 36, a pressure-resistant sealing device 80, and a pressure-resistant internal door 35. A pressure valve 15 and a vent valve are installed inside the pressure-resistant housing 39. A clothes rack is placed inside the pressure-resistant housing 39. After the clothes are sprayed with deodorizing agent, they are subjected to high pressure or vibration by a vibration device 48 to expel exhaust gas. Alternatively, after the clothes are sprayed with fragrance or medicine, high pressure is applied or a vibration device 48, which generates vibration at a certain frequency, is installed inside the pressure-resistant housing 39. This vibration device can vibrate the clothes inside the deodorizing and fragrance-adding machine. Under high pressure, the fragrance or medicine penetrates the clothes strongly. The vibration by the vibration device 48 enhances the penetration function. After continuous high-pressure treatment, the air is released through the safety valve 46 to a normal pressure state, and the clothes are then removed.

[0331] The valve housing 73 is provided with a pressurization port 62 (A), a pressure reduction port 69 (B), an air extraction port 71 (D), an air filling port 68 (C), a circulation air inlet 63 (E), and a circulation air outlet 70 (F); the valve body 66 is provided with a three-way hole 64, a circulation air inlet 74, and a circulation air outlet 75.

Alternatively, a vibration device 48 is installed inside the chamber, integrated with the rack 57. The foot care chamber is then vented through the suction valve to create low pressure. Sweat and odor expand and decompose under this low pressure, and are then expelled from the chamber through a safety valve 32. Alternatively, the odor is treated with a deodorizing and purifying agent, vibrated by the vibration device 48, and then vented through the suction valve to create low pressure. After continuous low-pressure treatment, the odor is vented back to normal pressure through the safety valve 32, at which point the shoes and socks 58 are removed.

[0333] According to the above structure, since multiple pressure-controlling housings 6 are combined or integrated on the high and low pressure compression device 1, a more efficient high-pressure or low-pressure environment is created. Multiple pressure-controlling housings 6 are provided on the high and low pressure compression device 1, and a pressure-controlling body 7 is provided inside each pressure-controlling housing 6. The bottom outer periphery or bottom cover of the pressure-controlling housing 6 is integrally or connected to the bottom cover.

The reciprocating motion of the pressure-controlling body 7 within the pressure-controlling housing 6 enlarges or reduces the space within the pressure-controlling housing 6. The air pressure inside the pressure-bearing housing 6 is increased or decreased several times, and then applied to the space inside the external equipment through the pressure-increasing valve 15 and the suction valve 11 in different connection ways, forming a high-pressure space greater than the atmospheric environment or a low-pressure space lower than the atmospheric environment. The technology of creating high-pressure or low-pressure spaces can be applied to refrigerators, washing machines, dishwashers, pickling machines, floor scrubbers, clothes cleaning machines and other various household appliances.
