The refilling docking unit 300 of the air conditioner 1000 according to the embodiment of the present invention will be described with reference to the accompanying drawings, and the air conditioner 1000 according to the present invention may be used to adjust the physicochemical properties of air, such as the temperature, humidity, cleanliness, smell, etc., of the conditioned air. The air conditioner 1000 according to the embodiment of the present invention includes the mobile sub-unit 200 and the main air conditioner 100, which are separable and attachable, as shown in fig. 1 and 14, the main air conditioner 100 includes the energy supply heat exchanger 120, and the energy supply heat exchanger 120 may generate cooling capacity or heating capacity. The cold quantity and the heat quantity are relative concepts, for example, the temperature of the refrigerant in the energy supply heat exchanger 120 is higher than the temperature in the air or the temperature of the component exchanging heat with the refrigerant, and the energy supply heat exchanger 120 has transferable heat quantity; conversely, when the temperature of the refrigerant in the energizing heat exchanger 120 is lower than the temperature of the air or the temperature of the component exchanging heat with the air, the energizing heat exchanger 120 has transferable cooling capacity.

As shown in fig. 4 and 6, the mobile sub-machine 200 includes an energy storage tank 212, an energy storage heat exchanger 211 disposed in the energy storage tank 212, and an energy storage medium further disposed in the energy storage tank 212. The energy storage medium is a medium capable of absorbing or releasing heat, for example, a phase change medium, or a non-phase change medium capable of generating a large temperature change, and the energy storage medium may exchange heat with the energy storage heat exchanger 211 to store a certain amount of heat. The recharging docking device 300 is arranged between the mobile sub-machine 200 and the air conditioner main machine 100, one of the mobile sub-machine 200 and the air conditioner main machine 100 is connected with the first docking component 310, and the other of the mobile sub-machine 200 and the air conditioner main machine 100 is connected with the second docking component 320.

A recharging docking device 300 of an air conditioner 1000 according to an embodiment of the present invention, as shown in fig. 3, includes: a first docking assembly 310 and a second docking assembly 320.

As shown in fig. 14, 15 and 20, the first docking assembly 310 includes a first valve body 311 and a first valve spool 312. As shown in fig. 15, 16, and 20, the first valve body 311 has a first flow passage 3111 and a first pair of ports 3112, and the first valve body 312 is provided movably in the first flow passage 3111 to close or open the first flow passage 3111.

Accordingly, as shown in fig. 8, 9 and 21, the second docking assembly 320 includes a second valve body 321 and a second valve spool 322, and as shown in fig. 8, 16 and 21, the second valve body 321 has a second flow passage 3211 and a second docking port 3212, and the second valve spool 322 is movably disposed in the second flow passage 3211 to block or block the second flow passage 3211.

The first docking assembly 310 and the second docking assembly 320 are detachably engaged, when the first docking assembly 310 and the second docking assembly 320 are engaged in place, the first valve core 312 and the second valve core 322 abut against each other to respectively conduct the first flow channel 3111 and the second flow channel 3211 and to communicate the two, and when the first docking assembly 310 and the second docking assembly 320 are disengaged, the first flow channel 3111 and the second flow channel 3211 are respectively blocked.

As can be seen from the above structure, the recharging docking device 300 according to the embodiment of the present invention can be used in an air conditioner 1000, wherein the first docking assembly 310 and the second docking assembly 320 can be respectively disposed on two separable and combinable components, that is, on the main air conditioner unit 100 and the mobile sub-unit 200, when the main air conditioner unit 100 and the mobile sub-unit 200 are combined, the first docking assembly 310 and the second docking assembly 320 are engaged in place, and the first flow channel 3111 and the second flow channel 3211 are conducted to facilitate the introduction of liquid; when the two components are separated, the first butt joint assembly 310 and the second butt joint assembly 320 are also disengaged, the first butt joint assembly 310 can be quickly stopped, the second butt joint assembly 320 can be quickly stopped, and therefore the scheme that the two components are communicated and filled in different states and liquid does not overflow outwards after separation is effectively achieved.

Then, when the recharging docking device 300 is used in the air conditioner 1000 according to the embodiment of the present invention, when the first docking assembly 310 and the second docking assembly 320 are engaged in place, the energy-supplying heat exchanger 120 may charge the refrigerant into the energy-storing heat exchanger 211, so that the refrigerant is continuously circulated and transferred between the energy-supplying heat exchanger 120 and the energy-storing heat exchanger 211. Meanwhile, the energy storage medium can exchange heat with the energy storage heat exchanger 211 and store part of heat or cold, so that the mobile sub-machine 200 has sufficient heat and cold for subsequent use.

The first butt joint component 310 and the second butt joint component 320 are convenient and quick to butt joint, so that the refrigerant is reliably transmitted between the air conditioner main unit 100 and the mobile sub-unit 200; and when the first butt joint component 310 is arranged on the air conditioner main unit 100 and the second butt joint component 320 is arranged on the mobile sub-unit 200, the first butt joint component 310 effectively prevents the refrigerant in the energy supply heat exchanger 120 from spilling outwards, and the second butt joint component 320 effectively prevents the refrigerant in the energy storage heat exchanger 211 from spilling outwards. The quick butt joint of the mobile sub-machine 200 and the air conditioner main machine 100 is possible, and the cold charging quantity or the heat charging quantity of the mobile sub-machine 200 is more convenient and faster.

It can be understood that the recharging docking device 300 of the present application does not need to rely on an electronic valve for stopping, but can realize fast docking and conducting and reliable stopping through the butting force generated by simple docking and separation. Compare in the mobile air conditioner product among the prior art, the air conditioner 1000 of this application adopts the back of specific structure to fill interfacing apparatus 300, need not to rely on automatically controlled valve, and occupation space is few when removing the submachine 200 and removing in a flexible way, and has the work persistence of preferred, and the refrigerant circulation is quick, convenient after the butt joint.

In some embodiments of the present invention, as shown in fig. 14, 15 and 20, the first docking assembly 310 further comprises a trigger 313. As shown in fig. 8, 9 and 21, the second docking assembly 320 further includes a limiting assembly 323 disposed on the second valve body 321. The limiting component 323 is switchable between a stopping state and a triggering state, in the stopping state, the limiting component 323 stops the second pair of interfaces 3212, the limiting component 323 is switched to the triggering state under the triggering of the triggering element 313, and in the triggering state, the limiting component 323 avoids the second pair of interfaces 3212 to enable the first valve element 312 and the second valve element 322 to be abutted. In these examples, by further providing the limit component 323 and the trigger 313, the limit component 323 is triggered by the trigger 313 in the process of docking the mobile handset 200 to the air conditioner main unit 100, so that the docking passage between the first valve element 312 and the second valve element 322 is communicated, and thus when the mobile handset 200 is further moved to the air conditioner main unit 100 and docked, the first valve element 312 can smoothly apply force to the second valve element 322, and the first flow passage 3111 and the second flow passage 3211 are respectively communicated and communicated by the abutting force of the first valve element 312 and the second valve element 322, so as to achieve quick docking. When the mobile sub-machine 200 is separated from the air conditioner main machine 100, the limiting component 323 is in the stop state again, and at the moment, the limiting component 323 is limited at the second pair of interfaces 3212, so that the second pair of interfaces 3212 can be effectively prevented from being triggered by other components by mistake, and the refrigerant leakage probability is effectively reduced.

Optionally, as shown in fig. 9 and 21, the limiting component 323 includes a limiting sheet 3231 and a connecting member 3232, the limiting sheet 3231 is movably disposed on the second valve body 321 through the connecting member 3232, in the stopping state, the limiting sheet 3231 shields the second pair of interfaces 3212, and in the triggering state, the limiting sheet 3231 shields the second pair of interfaces 3212. Here, the second connector 3232 allows the stopper piece 3231 to move not only in one direction but also in a plurality of directions with respect to the stopper piece 3231. When moving in one direction, the limiting piece 3231 may move along the radial direction of the second valve body 321, or the limiting piece 3231 may move along the axial direction of the second valve body 321, which is not limited specifically here, as long as the limiting piece 3231 can shield the second valve core 322 at the second pair of interfaces 3212. When moving in multiple directions, the limiting piece 3231 may move along the radial direction or the axial direction of the second valve body 321 at the same time, and the stopping function of the limiting piece 3231 is more reliable.

Alternatively, as shown in fig. 9 and 21, the limiting sheet 3231 has a communication port 3231a, and in the stop state, the communication port 3231a is disposed in a staggered manner with respect to the second pair of interfaces 3212; in the triggered state, the communication port 3231a is disposed opposite to the second pair of interfaces 3212. That is, when the communication port 3231a of the stopper piece 3231 is not aligned with the second pair of ports 3212, the first valve element 312 cannot abut against and interact with the second valve element 322, and when the stopper piece 3231 is aligned with and coaxial with the second pair of ports 3212, the first valve element 312 and the second valve element 322 form a reliable and smooth abutting joint, so that the refrigerant flows. In these examples, when the communication port 3231a and the second pair of ports 3212 are switched between alignment and misalignment, the stopper piece 3231 moves in the radial direction of the second valve body 321.

Of course, in another embodiment of the present invention, the limiting sheet 3231 may not be provided with the communication port 3231a, but merely stop on a path where the first valve core 312 and the second valve core 322 are butted, and in the stop state, the limiting sheet 3231 stops at the second butt joint 3212 to prevent the external component from further moving toward the second valve core 322.

Advantageously, as shown in fig. 9, the stopper piece 3231 is provided with a shaped opening 3231b, and the connecting member 3232 is movably provided in the shaped opening 3231b, and when the stopper piece 3231 is triggered by the trigger 313, the connecting member 3232 moves in the shaped opening 3231b and switches positions, thereby switching the position of the stopper piece 3231 in a radial direction with respect to the second valve core 322.

The special-shaped port 3231b can be two communicated holes with different radiuses, and meanwhile, the connecting piece 3232 is provided with a necking groove which limits the port wall of the special-shaped port 3231b, so that the limiting piece 3231 can be arranged on the second valve body 321 through the connecting piece 3232 all the time, and the limiting piece 3231 cannot fall off or be blocked when being switched between a stopping state and a triggering state.

Advantageously, as shown in fig. 9 and 21, the stop assembly 323 further comprises: the first elastic member 3233, the first elastic member 3233 is disposed between the connecting member 3232 and the second valve body 321, the connecting member 3232 is movable along the axial direction of the second valve body 321, and when the connecting member 3232 moves toward the second valve body 321, the first elastic member 3233 stores force and easily resets the connecting member 3232 so that the stopper piece 3231 can be quickly reset to the stopping state.

In these examples, correspondingly, a mounting groove extending in the axial direction is provided on the second valve body 321, and the first elastic element 3233 is disposed in the mounting groove and can extend and contract relative to the mounting groove, so that the connecting element 3232 can repeatedly extend and contract along the axial direction of the second valve body 321, and further drives the limiting piece 3231 to move in the axial direction relative to the second valve body 321.

Advantageously, as shown in fig. 9, the limiting assembly 323 further includes a second elastic member 3234, and the second elastic member 3234 is disposed between the limiting piece 3231 and the second valve body 321 to drive the limiting piece 3231 to be maintained in the stopping state, in these examples, the second elastic member 3234 is different from the first elastic member 3233 in the extending and retracting direction, so that the limiting piece 3231 can move in different directions relative to the second valve body 321.

When the limiting sheet 3231 is in the stopping state, the second elastic element 3234 acts to make the communication port 3231a of the limiting sheet 3231 and the second pair of ports 3212 form a misalignment, and the connecting element 3232 further stops against one end of the special-shaped port 3231 b.

Alternatively, as shown in fig. 14, 15 and 20, the triggering member 313 of the present invention is a rib provided on the first valve body 311, and the radial dimension of the rib is larger than the outer diameter of the first valve core 312, so that when the first valve body 311 approaches the second valve body 321, the rib on the first valve body 311 preferentially contacts the limiting sheet 3231, so that the limiting sheet 3231 is triggered and moved, and the limiting sheet 3231 is switched from the stop state to the trigger state.

On the contrary, when the first docking assembly 310 moves in a direction away from the second docking assembly 320, the second valve core 322 and the first valve core 312 are separated in the axial direction, the sealing ring no longer applies force to the limiting sheet 3231, the limiting sheet 3231 returns to the stopping state under the action of the spring force, and the first valve core 312 stops the first flow passage 3111, and the second valve core 322 stops the second flow passage 3211.

That is, one end of the first valve element 312 forms a first valve element port 3121 that is axially opened toward the first pair of ports 3112, while the other end of the first valve element 312 is axially closed but has a first notch 3122 opened in a side wall thereof, and when the first notch 3122 is exposed and positioned in the first communication cavity 3111b, the refrigerant may enter the flow passage in the first valve element 312 along a radial direction of the first notch 3122 and further flow in the axial direction and flow out toward the first valve element port 3121. As long as the first notch 3122 is not exposed to the first communication chamber 3111b but hidden in the first cut-off flow passage 3111a, refrigerant does not pass through the first valve body 312.

Accordingly, as shown in fig. 16 and 18, the second flow path 3211 includes a second cut-off flow path 3211a and a second communication chamber 3211b which communicate with each other in the mating direction, as shown in fig. 9, one end of the second valve element 322 forms an axial second valve element port 3221, the second valve element port 3221 does not exceed the second pair of ports 3212, and a second notch 3222 is formed in a side wall of the other end of the second valve element 322.

That is, one end of the second valve element 322 forms a second valve element port 3221 which is axially opened toward the second pair of ports 3212, while the other end of the second valve element 322 is axially closed but has a second gap 3222 opened in the sidewall, and when the second gap 3222 is exposed and located in the second communication chamber 3211b, the refrigerant can enter the flow passage of the second valve element 322 along the radial direction of the second gap 3222, and further flow axially and flow out toward the second valve element port 3221. Similarly, as long as the second notch 3222 is hidden in the second blocking flow passage 3211a without being exposed to the second communication chamber 3211b, no refrigerant passes through the second valve spool 322.

That is, when the second valve core 322 is pressed, the fourth elastic member 326 is compressed to store force, and when the pressing force applied to the second valve core 322 disappears or is weakened, the fourth elastic member 326 releases the force and drives the second valve core 322 to reset, so that the second notch 3222 of the second valve core 322 is hidden in the second stopping flow passage 3211b again, and when the first valve core 312 is separated from the second valve core 322, the second valve core 322 can be stopped, and the refrigerant is prevented from further flowing outwards.

Alternatively, the third elastic member 316 and the fourth elastic member 326 may exist at the same time, or only one of them may be provided.

Advantageously, as shown in fig. 9 and 16, an end of the second valve core 322 close to the second gap 3222 is provided with a second stop portion 327, and the second stop portion 327 can block the second stopping flow passage 3211 a. That is, when the second notch 3222 is hidden in the second blocking flow passage 3211a, the second stopper portion 327 blocks the second blocking flow passage 3211a, so that the refrigerant in the second communication chamber 3211b does not flow to the second valve body 322 any more and does not flow out of the second blocking flow passage 3211 a.

In some specific examples, as shown in fig. 16, one end of the third elastic member 316 is disposed on the first stop portion 317, and the other end of the third elastic member 316 is disposed on the inner wall of the first valve body 311, so as to effectively ensure that the third elastic member 316 releases the force to drive the first stop portion 317 to stop against the wall surface of the first communication cavity 3111b transitioning to the first stop flow channel 3111a, thereby separating the first communication cavity 3111b from the first stop flow channel 3111a and stopping the first stop flow channel 3111 a; similarly, one end of the fourth elastic element 326 is disposed on the second stopper portion 327, and the other end of the fourth elastic element 326 is disposed on the inner wall of the second valve body 321, so as to effectively ensure that the fourth elastic element 326 drives the second stopper portion 327 to abut against the wall surface of the second communicating cavity 3211b, which transitions to the second blocking flow channel 3211a, after releasing the force, thereby separating the second blocking flow channel 3211a from the second communicating cavity 3211b, and blocking the second blocking flow channel 3211 a.

Advantageously, the wall of the first connection space 3111b that transitions into the first stop channel 3111a is formed as a conical wall, and the contour of the first stop 317 is formed as a wedge-shaped surface, so that the first stop 317 rests against the conical wall and effective sealing is achieved.

Similarly, the wall surface of the second communication chamber 3211b that transitions to the second blocking flow passage 3211a is formed as a tapered wall surface, and the contour of the second stopper portion 327 is formed as a tapered surface, so that the second stopper portion 327 abuts against the tapered wall surface to achieve effective blocking.

Optionally, as shown in fig. 15, the first docking assembly 310 further includes a first sealing member 318, and the first sealing member 318 is disposed on the first stop portion 317, so that when the first valve core 312 returns to the first stop channel 3111a, the first sealing member 318 can further seal and block the first stop channel 3111a, thereby greatly reducing the possibility of liquid leakage.

Optionally, as shown in fig. 9, the second docking assembly 320 further includes a second sealing member 328, and the second sealing member 328 is disposed on the second stopping portion 327, so that when the second valve spool 322 returns to the second stopping flow passage 3211a, the second sealing member 328 can further seal and block the second stopping flow passage 3211a, thereby greatly reducing the possibility of liquid leakage.

In a specific example of the present invention, two sets of the first docking assembly 310 and the second docking assembly 320 are provided, wherein one of the first docking assembly 310 serving as an inlet is docked with one of the second docking assembly 320 serving as an outlet, and the other of the first docking assembly 310 serving as an outlet is docked with the other of the second docking assembly 320 serving as an inlet, so that the first valve spool 311 and the second valve spool 321 are communicated when the mobile handset 200 is in a combined state with respect to the main air conditioner 100, and one pair of the docked first docking assembly 310 and the docked second docking assembly 320 can convey the refrigerant in the energy storage heat exchanger 120 to the energy storage heat exchanger 211, and the other pair of the docked first docking assembly 310 and the docked second docking assembly 320 can convey the refrigerant in the energy storage heat exchanger 211 to the energy storage heat exchanger 120, so as to form a closed-loop circulation flow of the refrigerant.

Advantageously, a quick plug is formed at a side of the first valve body 311 facing the cooling liquid inlet pipe 161 or the cooling liquid outlet pipe 162, so that the first valve body 311 is conveniently communicated with the cooling liquid inlet pipe 161 or the cooling liquid outlet pipe 162, and thus, the refrigerant can flow into the first communication cavity 3111b in the first valve body 311.

Advantageously, the second valve body 321 is formed with a quick plug at a side facing the heat accumulation inlet pipe 261 or the heat accumulation outlet pipe 262, so that the second valve body 321 is conveniently communicated with the heat accumulation inlet pipe 261 or the heat accumulation outlet pipe 262, thereby allowing the refrigerant introduced into the second valve body 321 to flow into the accumulator heat exchanger 211.

An air conditioner 1000 employing the above-described recharging docking assembly 300 in an example of the present invention is further described below.

An air conditioner 1000, as shown in fig. 4 and fig. 6, the mobile sub-machine 200 further comprises a mobile sub-machine housing 270, a pump body 230, an indoor heat exchanger 220 and a fan component 280, an air duct 271 is formed in the mobile sub-machine housing 270, and the air duct 271 is communicated with an air inlet 272 and an air outlet 273; the indoor heat exchanger 220 and the fan unit 280 are provided in the air passage 271. The mobile sub-machine shell 270 can effectively protect each internal component. The pump body 230 circulates the refrigerant between the components connected thereto. The indoor heat exchanger 220 can exchange heat between the heat of the indoor heat exchanger and the wind introduced into the mobile sub-machine 200. When the fan part 280 works, indoor wind can be introduced into the air channel 271 through the air inlet 272, and then introduced into the indoor heat exchanger 220 to be discharged from the air outlet 273 to the indoor space after heat exchange, so that the indoor heat exchanger 220 can regulate the temperature of indoor air flow.

The energy storage heat exchanger 211 is in contact with an energy storage medium, and the air conditioner main unit 100 and the mobile sub unit 200 have a separated state and an integrated state. In the disengaged state, the first docking assembly 310 and the second docking assembly 320 are disengaged; referring to fig. 6 and 12, the energy storage medium cools or releases heat toward the energy storage heat exchanger 211, and the pump body 230 drives the refrigerant to circulate between the energy storage heat exchanger 211 and the indoor heat exchanger 220. The refrigerant circulates in the mobile sub-unit 200 at this time, and the mobile sub-unit 200 can continue a certain cooling or heat releasing process in a state of being separated from the air conditioner main unit 200.

In the joined state, the first docking assembly 310 and the second docking assembly 320 are mated in place; the energy supply heat exchanger 120 is communicated with the energy storage heat exchanger 211, the energy storage heat exchanger 211 is disconnected from the indoor heat exchanger 220, and as shown in fig. 8 and 14, the pump body 230 drives the refrigerant to circulate between the energy supply heat exchanger 120 and the energy storage heat exchanger 211. At this time, the refrigerant continuously flows between the energy supply heat exchanger 120 and the energy storage heat exchanger 211, so that the energy transmission of the air conditioner main unit 100 to the mobile sub-unit 200 can be realized, and meanwhile, the energy storage medium can further store the energy transmitted in place, so that the mobile sub-unit 200 has a certain amount of heat release or heat release.

As can be seen from the above structure, in the air conditioner 1000 according to the embodiment of the present invention, the energy supply heat exchanger 120 has a preset refrigerant with a low heat exchange temperature or a high temperature, so that the energy supply heat exchanger 120 has sufficient cooling capacity or heat capacity to transfer to the mobile sub-machine 200. In this application, the default is that the temperature of the refrigerant in the energy supply heat exchanger 120 is significantly lower than the temperature of the refrigerant in the energy storage heat exchanger 211 when the mobile sub-machine 200 needs to be charged with cold. On the other hand, when the mobile handset 200 needs to be charged with heat, the temperature of the refrigerant in the energizing heat exchanger 120 is significantly higher than the temperature of the refrigerant in the accumulator heat exchanger 211.

When the air-conditioning main unit 100 charges the mobile sub-unit 200 in a state that the mobile sub-unit 200 is combined with the air-conditioning main unit 100, the refrigerant with lower temperature in the energy supply heat exchanger 120 and the refrigerant with higher temperature in the energy storage heat exchanger 211 are continuously circulated to gradually lower the temperature of the refrigerant in the energy storage heat exchanger 211, and meanwhile, the energy storage heat exchanger 211 further exchanges heat with the energy storage medium, so that the energy storage medium further absorbs cold energy and stores a certain amount of cold energy.

When the main air conditioner 100 charges the mobile sub-machine 200, the refrigerant with higher temperature in the energy supply heat exchanger 120 and the refrigerant with lower temperature in the energy storage heat exchanger 211 circulate continuously to gradually raise the temperature of the refrigerant in the energy storage heat exchanger 211, and meanwhile, the energy storage heat exchanger 211 further exchanges heat with the energy storage medium, so that the energy storage medium further absorbs heat and stores a certain amount of heat.
