DETAILED DESCRIPTION
[0020] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] like Figure 1 and Figure 2 As shown, an adsorption refrigeration device with embedded magnetic vacuum valves includes at least two adsorption beds, an evaporator 3, a condenser 4 and multiple embedded magnetic vacuum valves;
[0022] At least two adsorption beds are respectively connected to the evaporator 3 and the condenser 4 , and embedded magnetic vacuum valves are respectively connected between the adsorption beds and the evaporator 3 and the condenser 4 .
[0023] In the present invention, the connection or closing state between the evaporator 3 and the adsorption bed and between the condenser 4 and the adsorption bed is switched by the embedded magnetic vacuum valve.
[0024] In the adsorption refrigeration device containing an embedded magnetic vacuum valve of the present invention, at least a plurality of adsorption beds are included, wherein the plurality of adsorption beds are arranged in parallel, that is, the adsorption beds are arranged compactly so that the spacing between the plurality of adsorption beds is small, and the plurality of adsorption beds are respectively connected to the condenser 4 and the evaporator 3.
[0025] In detail, at least two adsorption beds are arranged in parallel, the condenser 4 is arranged above the adsorption bed and is connected to the adsorption bed through an embedded magnetic vacuum valve; the evaporator 3 is arranged below the adsorption bed and is connected to the adsorption bed through an embedded magnetic vacuum valve.
[0026] Secondly, since embedded magnetic vacuum valves are provided between the adsorption bed and the evaporator 3, and between the adsorption bed and the condenser 4, the connection between the adsorption bed and the evaporator 3 and / or between the adsorption bed and the condenser 4 can be opened or disconnected by the embedded magnetic vacuum valves.
[0027] Furthermore, in the present invention, embedded magnetic vacuum valves are provided between the adsorption bed and the evaporator 3 and / or between the adsorption bed and the condenser 4. The embedded magnetic vacuum valves can reduce the space between the adsorption bed and the evaporator 3 and the condenser 4, respectively, thereby further reducing the overall volume of the refrigeration device.
[0028] Fourth, in the adsorption refrigeration device with an embedded magnetic vacuum valve of the present invention, since it includes at least two adsorption beds, the at least two adsorption beds can alternately adsorb and desorb. While the volume of the refrigeration device of the present invention is reduced, the alternating adsorption and desorption effect of the two adsorption beds can be achieved, thus achieving non-stop operation and improving operating efficiency.
[0029] As a first embodiment of the present invention, at least two adsorption beds include a first adsorption bed 1 and a second adsorption bed 2, the first adsorption bed 1 and the second adsorption bed 2 are arranged side by side on the left and right, the evaporator 3 is connected to the bottom of the first adsorption bed 1 and the second adsorption bed 2, and the condenser 4 is connected to the top of the first adsorption bed 1 and the second adsorption bed 2. The condenser 4, the first adsorption bed 1, the evaporator 3 and the second adsorption bed 2 form a circulation channel.
[0030] The present invention includes an embedded magnetic vacuum valve, wherein the embedded magnetic vacuum valve is respectively arranged between the adsorption bed and the evaporator 3 and between the adsorption bed and the condenser 4, and the connection between the adsorption bed and the condenser 4 and between the adsorption bed and the evaporator 3 is controlled by the embedded magnetic vacuum valve.
[0031] In detail, in combination with the above embodiments, the adsorption refrigeration device with an embedded magnetic vacuum valve of the present invention includes two adsorption beds, namely a first adsorption bed 1 and a second adsorption bed 2.
[0032] Since the first adsorption bed 1 and the second adsorption bed 2 are respectively connected to the condenser 4 and the evaporator 3, a first magnetic vacuum valve 6 is provided between the first adsorption bed 1 and the condenser 4, a second magnetic vacuum valve 5 is provided between the first adsorption bed 1 and the evaporator 3, a third magnetic vacuum valve 8 is provided between the second adsorption bed 2 and the condenser 4, and a fourth magnetic vacuum valve 7 is provided between the second adsorption bed 2 and the evaporator 3.
[0033] Furthermore, each embedded magnetic vacuum valve includes a cover plate 10 and a base plate 9, the cover plate 10 is tightly connected to the base plate 9, and the cover plate 10 can be opened relative to the base plate 9;
[0034] A plurality of closely arranged coils 11 are arranged along the circumference of the cover plate 10 , and the plurality of coils 11 are wound up and down; a plurality of vertically arranged magnetic strips 12 are arranged along the circumference of the chassis 9 , and a plurality of connecting holes 13 are provided at the lower part of the chassis 9 .
[0035] It should be noted that the orientation of the magnetic strip 12 is the same as the orientation of the evaporator 3, condenser 4, and adsorption bed. That is, the orientation of the magnetic strip 12 is consistent with the orientation of the evaporator 3 and the condenser 4, respectively, with the adsorption bed. In other words, when the condenser 4, adsorption bed, and evaporator 3 are arranged vertically, the magnetic strip 12 is arranged vertically.
[0036] Preferably, the chassis 9 is made of stainless steel, and the cover 10 is made of silicone. The cover 10 is neither magnetic nor conductive, thus preventing the cover 10 from affecting the magnetic poles.
[0037] In detail, the working principle of the embedded magnetic vacuum valve in the present invention is to use the energized coil 11 to generate magnetic force to realize the opening and closing of the valve.
[0038] Because multiple closely spaced coils 11 are arranged around the circumference of cover plate 10, and multiple coils 11 are wound around it, and multiple vertically arranged magnetic strips 12 are arranged around the circumference of chassis 9, and multiple communication holes 13 are provided at the bottom of chassis 9, connecting the upper and lower surfaces of the upper and lower chassis 9, the vertical arrangement of magnetic strips 12 is preferred to ensure the orientation of the magnetic poles generated by energizing coils 11. Because condenser 4, evaporator 3, and adsorption bed are arranged vertically, magnetic strips 12 are preferably arranged vertically with north and south poles.
[0039] During use, the coil 11 is energized. When the magnetic poles generated by the energized coil 11 are the same as the magnetic poles of the magnetic stripe 12 on the cover 10, the cover 10 and the chassis 9 repel each other, the cover 10 opens, and the embedded magnetic vacuum valve is opened. By changing the direction of the energized current of the coil 11 so that the magnetic poles generated by the energized coil 11 are opposite to the magnetic poles of the magnetic stripe 12 on the cover 10, the cover 10 and the chassis 9 attract each other, the cover 10 closes, and the embedded magnetic vacuum valve is closed.
[0040] The working process of the present invention:
[0041] Combine Figure 1 To illustrate, the first adsorption bed 1 is heated, desorbed from the first adsorption bed 1 to produce gaseous refrigerant, and the first magnetic vacuum valve 6 is energized so that the magnetic poles generated by the coil 11 in the cover plate 10 are aligned with the magnetic poles of the magnetic strips 12 on the chassis 9. At this point, the first magnetic vacuum valve 6 opens, and the gaseous refrigerant enters the condenser 4 through the connecting hole 13 for condensation. Simultaneously, the third magnetic vacuum valve 8 is energized so that the magnetic poles generated by the coil 11 in the cover plate 10 are opposite to the magnetic poles of the magnetic strips 12 on the chassis 9. The third magnetic vacuum valve 8 is closed.
[0042] At the same time, the second adsorption bed 2 is condensed, and the evaporator 3 evaporates to produce gaseous refrigerant. At this time, the fourth magnetic vacuum valve 7 is energized so that the magnetic poles generated by the coil 11 in the cover plate 10 are the same as the magnetic poles of the magnetic strips 12 on the chassis 9. At this time, the fourth magnetic vacuum valve 7 is opened, and the gaseous refrigerant enters the second adsorption bed 2 through the connecting hole 13 for adsorption; at the same time, the second magnetic vacuum valve 5 is energized so that the magnetic poles generated by the coil 11 in the cover plate 10 are opposite to the magnetic poles of the magnetic strips on the chassis 9, and the second magnetic vacuum valve 5 is closed.
[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
