Background technique

At present, in the hot summer or in some high-temperature working environments, indoor air conditioners are usually used to cool the overall environment so as to improve the living or working environment. However, in many cases, for example, the heat source is point radiation, and the use of air conditioners to cool the overall environment is not enough to reduce the temperature near the heat source, so the operators working near the heat source still suffer from high temperature; in addition, in some cases, the temperature is high. Operators of the environment may need to operate in multiple locations or outdoors. Therefore, the use of indoor air conditioners cannot meet the requirements for cooling the operators. In addition, in some cases, it may only be necessary to cool a certain point or a certain person.

In some embodiments, the circulation component 13 can blow the cooling air to the two horizontally arranged air outlets 113 and into the airflow guide component. Through the circulation component, the cooling air is efficiently blown to the airflow guide component, which improves the circulation efficiency of the cooling air.

Of course, it should be understood that the above-mentioned embodiment in which the circulation assembly 13 adopts a centrifugal fan is only illustrative, and is not intended to limit the protection scope of the present disclosure. Any other suitable devices or arrangements are also possible. For example, in some alternative embodiments, the circulation assembly 13 may also adopt an axial flow fan or any other suitable fan.

In some embodiments, the evaporation assembly 14 may be an evaporator, which may take the form of an evaporator known in the art for use in air conditioners. In some embodiments, the condensing assembly 15 may be a condenser or include a condenser and a filter.

In some embodiments, for example, referring to FIGS. 1, 3, and 8-9, the evaporation assembly 14 may be fixed on the evaporator fixing portion 114 on the bottom plate 11, and the evaporator fixing portion 114 is located on the bottom plate 11 near the circulation assembly. In the area of 13. In some embodiments, for example, the plane where the evaporator fixing portion 114 is located is arranged at an angle relative to the plane where the bottom plate 11 is located, and the included angle between the two is, for example, greater than 0 degrees to less than 45 degrees, more particularly 0-30 degrees, More specifically, the included angle is 0-20 degrees, especially 5-10 degrees, so that the evaporator fixing portion 114 is arranged obliquely with respect to the plane where the bottom plate 11 is located.

In some embodiments, an air inlet 1141 may be provided on the obliquely arranged evaporator fixing portion 114. For example, after the refrigeration cycle device is worn on matching clothes or attached to the human body, compared to the vertical arrangement As for the air inlet, the air inlet 1141 is basically in a non-vertical air inlet state, that is, in an inclined direction. This arrangement is more conducive to sucking the hot air around the human body into the refrigeration component for cooling, so that the human body to be cooled can be rapidly cooled.

It is worth noting that the plane where the evaporator fixing part 114 is located is arranged at an angle relative to the plane where the bottom plate is located, that is, the advantage of the inclined arrangement is that it can prevent the bottom plate from being too tightly attached to the human body, facilitate air intake, and facilitate condensation. Discharge of water.

In some embodiments, as shown in FIG. 10, the bottom plate 11 may further include an auxiliary spacer 115, which is arranged on a side of the bottom plate 11 close to the human body. The auxiliary spacer 115 may be made of a soft material. For example, the two ends of the auxiliary spacer 115 can be respectively fixed on both sides of the evaporator fixing portion 114, thereby further forming a space between the human body and the evaporator fixing portion 114, preventing clothes from being adsorbed on the air inlet, and further improving cooling Air inlet effect of circulating equipment.

In some embodiments, as shown in FIG. 6, the refrigeration cycle device may further include a circuit board, and the circuit board may be disposed on the evaporation assembly 14. Via the evaporation assembly 14, the evaporation assembly 14 can cool the circuit board. This arrangement can prevent the circuit board from overheating and improve the reliability of the system.

The condensing assembly 15 may include a condenser and one or more condensing fans 151 (as shown in FIG. 6) stacked on the condenser. The condensing fan 151 may be arranged in such a way that it overlaps the condenser with respect to the bottom plate 11. This arrangement can make the space layout more compact and facilitate heat conduction.

In some embodiments, as shown in FIGS. 1 and 3, the housing 1 may further include a rear shell 12, and the rear shell 12 may be coupled with the bottom plate 11 to enclose the refrigeration assembly. For example, after the refrigeration assembly is installed on the bottom plate 11, the rear shell 12 is coupled with the bottom plate 11 to enclose the refrigeration assembly. The rear shell 12 is provided with a condensing component air inlet 121 and a condensing component air outlet 123 (see FIG. 1). In some embodiments, the condensing fan and the condenser may be arranged adjacent to the air inlet of the condensing component on the rear housing 12. For example, the condensing fan 151 may be two arranged side by side (see FIG. 6).

As shown in FIGS. 1 to 4, the air flow guide assembly is used to guide the cooling air discharged from the air outlet 113 to the human body, thereby cooling the human body. The airflow guide assembly includes a first guide 21 and a second guide 22, and the second guide 22 is pivotally coupled to the first guide 21. By using the pivotally connected first guide 21 and the second guide 22, the position of the cold air outlet 224 of the refrigeration cycle device can be conveniently adjusted and changed, which is convenient for the user to wear and cool the human body more efficiently.

As shown in Figures 1 to 5, the first guide 21 is used to form a first flow path, which is coupled to the housing 1, and is fluidly coupled with the exhaust port 113, so that the exhaust gas discharged from the exhaust port 113 The cooling air can enter the first flow path. The first guide 21 includes a pivot section 213 for realizing a pivot connection between the first guide 21 and the second guide 22.

The second guide 22 is pivotally coupled to the pivot section 213, for example, after the refrigeration cycle device is attached to the back of the human body, the second guide 22 can rotate between the two sides and the front side of the human body.

With this arrangement, when the user needs to wear the refrigeration device, the second guide 22 can be pivoted to both sides of the human body, so that the user can wear it very conveniently. After being worn, the second guide 22 can be pivoted to the waist of the human body for cooling the human body. When the refrigeration cycle device needs to be taken off, the second guide 22 can be pivoted to both sides. In this way, the air-conditioning garment of the present disclosure can adapt to users of various body types, and at the same time, it is convenient for users to wear and take off the refrigeration cycle equipment.

In some embodiments, the first guide 21 may be, for example, a pipe capable of forming a first fluid path, and is coupled to the housing 1, so as to guide the cooling air from the first end 111 of the bottom plate to the second end 112, thereby Extend to the outside of the housing. The second guide member may be a pipe pivotally connected to the first guide member 21 to realize the change of the position of the cold air outlet of the cooling air and facilitate the user to wear the refrigeration cycle equipment.

In some embodiments, the bottom plate 11 may further include a groove 110. As shown in Figures 1-2, the groove 110 extends from the air outlet 113 in the vertical direction X toward the second end 112 or extends from the first end 111 toward the second end 112 (that is, it has horizontally extending groove sections and vertical Straight extending groove section, as shown in Figure 2).

As shown in FIGS. 1-4, along the vertical direction X, the first guide 21 may sequentially include a first covering section 211, a second pipe section 212, and a pivot section 213. And, a part of the first guide 21 (for example, the first covering section 211 in FIG. 2) fluid-tightly covers the groove 110, so that the groove 110 of the bottom plate 11 and the first covering section 211 of the first guide 21 A part of the first flow path is formed therebetween. In this way, the cold air discharged from the air outlet 113 first passes through a part of the first flow path formed by the groove 110 and the first covering section 211, and then flows into the flow path formed by the second pipe section 212 located outside the housing 1 (As shown in Figure 4).

Using the groove 110 on the bottom plate and the first guide 21 to jointly define the first flow path can make full use of the space of the housing and reduce the volume of the refrigeration cycle equipment.

In some embodiments, as shown in FIGS. 4 to 5, the pivot section 213 of the first guide 21 may be located outside the housing 1, and includes a ventilation structure 215, as shown in FIGS. 1-4. The cooling air is guided from the first flow path to the second flow path via the ventilation structure 215.

The pivot section can not only realize the pivoting of the second guide, but also realize the fluid communication between the first flow path and the second flow path. The simple structure realizes the change of the air outlet position of the refrigeration cycle equipment, which is convenient for users to wear And cool the human body more efficiently.

In some embodiments, the ventilation structure 215 may be an opening, a plurality of through holes, a slot, and the like formed on the pivot section 213.

Of course, it should be understood that the above-described embodiments regarding the communication of the first flow path and the second flow path through the vent structure 215 of the pivot section are only exemplary, and are not intended to limit the protection scope of the present disclosure. Any other suitable structure or arrangement is possible. For example, in some alternative embodiments, only the pivot section may be used to realize the pivotal movement between the first guide 21 and the second guide 22, and the second pipe section 212 and the second guide section 212 of the first guide 21 Flexible pipes are arranged between the guides 22 to realize fluid communication between the first flow path and the second flow path.

In some embodiments, as shown in FIG. 7, the pivoting portion of the pivot section 213 may have a cylindrical structure, and two ends of the pivot section 213 are arranged with rotating collars 216 with a diameter larger than the diameter of the cylinder. The ventilation structure 215 is provided on the cylindrical structure. The pivot section can not only realize the pivoting of the second guide, but also realize the fluid communication between the first flow path and the second flow path. The simple structure realizes the change of the cold air outlet position of the refrigeration cycle equipment, which is convenient for users to wear And cool the human body more efficiently.

In some embodiments, as shown in FIGS. 1 to 3 and 7, the second guide member 22 may include two

guide housings

221 and 222 buckled together. In this way, the second guide can be easily processed and manufactured, while the second flow path can be easily formed and the airtightness of the flow path can be ensured.

As shown in Figures 1 and 7, one end of the two guiding

housings

221, 222 is respectively provided with a semicircular through hole 223, and the two semicircular through holes 223 are matched with the pivot section 213, so that the two semicircular through holes 223 The circular through holes 223 may be combined to form a through hole suitable for receiving the pivot section 213. In this way, when the two

guide housings

221, 222 are snapped together, the pivot section 213 is pivotally and fluid-tightly received in the through hole formed by the two semicircular through holes.

In some embodiments, both ends of the two semi-circular through holes 223 are respectively provided with notches suitable for accommodating the rotating collar 216, so that when the two guiding

housings

221, 222 are buckled together, the rotating The collar 216 is pivotally engaged in the notch, thereby partially enclosing the cylindrical body in the space formed by the two guiding housings 221, 222 (ie, in the second flow path). In this way, both the pivoting movement is achieved and the air tightness of the flow path is ensured.

In some embodiments, sliding seal rings may be provided on both sides of the rotating collar 216 respectively, so as to achieve a fluid seal between the pivot section 213 and the second guide member 22. Of course, a rotating collar 216 and a rotating sealing ring arranged in the slot can also be used to achieve fluid sealing between the pivot section 213 and the second guide 22.

In some embodiments, the second guide 22 may adopt a curved extension structure adapted to the structure of the human body. As shown in FIG. 7, the second guide 22 may further include a fan mounting portion 225 and a cold air outlet 224. The fan mounting portion 225 and the cold air outlet 224 are installed at the other end opposite to the semi-circular through hole and are adjacent to each other or arranged at One end away from the semicircular through hole 223. Of course, in some embodiments, the fan mounting part 225 may not be provided in the second guide 22, that is, the fan is not installed.

The fan installation part 225 is used to install a centrifugal fan. Through the jet effect of the centrifugal fan, the rate at which cooling air is blown to the human body can be increased and the cooling effect can be improved. Of course, the centrifugal fan can be replaced with an axial fan or any other suitable fan.

The fan outlet or cold air outlet 224 of the centrifugal fan is positioned between the user's skin and the user's clothes. In this case, the user's skin and clothing are not closely attached, but there is a certain gap. In this way, an air flow channel is formed between the user's skin and the inner surface of the clothes. The air blown into the clothes by the centrifugal fan will diffuse along the air flow channel, so that the user feels cool and comfortable.

For centrifugal fans, when the high-speed air stream or jet flowing out of the fan outlet of the fan enters the above-mentioned passage formed between the user's skin and clothes, there will be a discontinuity surface of unequal speed between the jet and the surrounding static air stream. Such discontinuous surfaces generally will inevitably undergo disturbances and lose their stability, resulting in vortices.

The generated vortex entrains the surrounding static air flow into the high-speed jet, and at the same time it continuously moves, deforms, and splits, thereby generating turbulence. After that, the turbulence gradually develops to the inner and outer sides to form a freely turbulent mixed layer, thereby strengthening the heat transfer ability of the air between the user's body and the clothes.

The air momentum is transferred laterally in the clothes, which makes the air stream caught in the high-speed jet from the centrifugal fan gain momentum, and then flows forward with the high-speed jet from the fan assembly. In this way, the momentum of the original air fluid is reduced and loses speed, thus forming a certain speed gradient. In this way, a shock is generated on the air-conditioning suit, thereby forming a pulse similar to water ripples.

Therefore, by implementing the fan as a centrifugal fan, the degree of turbulence of the air fluid can be increased, and the flow heat exchange in the passage formed between the clothes and the user's skin can be enhanced. In this way, the improved centrifugal fan and cold air outlet structure can increase the evaporation efficiency of sweat on the surface of the user's body and accelerate the evaporation of sweat. As a result, the heat generated by the human body can be quickly taken away by the air ejected by the fan assembly, thereby obtaining a better cooling effect than an axial fan.

Through the circulation function of the circulation component and the dual circulation function of the fan in the fan installation part, the flow rate of the cooling air is increased, and the cooling efficiency and the comfort of the human body are improved.

In some embodiments, the cold air outlet 224 may be jointly formed by the air outlet openings 2241 provided on the two guiding

housings

221 and 222, and blow the cooling air toward the human body. For example, when the two guiding
