An air conditioner 1000 according to an embodiment of the first aspect 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, and the like of conditioned air.

An air conditioner 1000 according to an embodiment of the present invention, as shown in fig. 1 and 2, includes: the air conditioner main unit 100 and the mobile sub-unit 200.

As shown in fig. 1 and 14, the main air conditioner 100 includes an energy supply device including an energy supply heat exchanger 120 that can generate cooling energy or heating energy. 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. 1 and 3, the mobile handset 200 is detachably provided to the air conditioner main unit 100. That is, the mobile handset 200 may be coupled to the air conditioner main unit 100 and mounted in place, or may be separated from the air conditioner main unit 100 and mounted.

As shown in fig. 4 and 6, the mobile sub-machine 200 includes an energy storage device 210, an indoor heat exchanger 220 and a pump body 230, wherein the energy storage device 210 can be used for storing a certain amount of heat or cold in the mobile sub-machine 200; the indoor heat exchanger 220 can exchange heat between the heat of the indoor heat exchanger and the air introduced into the mobile sub-machine 200; the pump body 230 circulates the refrigerant between the components connected thereto.

As shown in fig. 3 and 5, the energy storage device 210 includes an energy storage heat exchanger 211 and an energy storage tank 212 provided with an energy storage medium, where the energy storage heat exchanger 211 is provided in the energy storage tank 212, and the energy storage medium refers to a medium that can absorb heat or release heat, such as a phase change medium, and may also be a non-phase change medium that can generate a large temperature change.

As shown in fig. 8 and 14, the accumulator heat exchanger 211 may be selectively connected to the indoor heat exchanger 220 or the energizing heat exchanger 120. Referring to fig. 1 and 3, in a state that the mobile sub-unit 200 is installed in place on the main air conditioner 100, the energy storage heat exchanger 211 is communicated with the energy supply heat exchanger 120 and drives a refrigerant to circulate between the energy supply heat exchanger 120 and the energy storage heat exchanger 211 through the pump body 230, the refrigerant continuously flows between the energy supply heat exchanger 120 and the energy storage heat exchanger 211 at the time, so that energy transmission from the main air conditioner 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 cold or heat release.

As shown in fig. 6 and 12, in a state where the mobile sub-unit 200 is separated from the air conditioner main unit 100, the energy storage heat exchanger 211 is connected to the indoor heat exchanger 220 and drives the refrigerant to circulate between the energy storage heat exchanger 211 and the indoor heat exchanger 220 through the pump body 230, and the refrigerant at this time circulates in the mobile sub-unit 200, so that the mobile sub-unit 200 can continue to perform a certain cooling or heat releasing process in a state where the mobile sub-unit 200 is separated from the air conditioner main unit 200.

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 mobile sub-machine 200 and the main air conditioner 100 are installed in place and the main air conditioner 100 charges the mobile sub-machine 200 with cold, 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 circulate continuously 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 and stores a certain amount of cold.

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.

When the energy storage device 210 of the mobile sub-unit 200 obtains a certain amount of energy, the mobile sub-unit 200 is separated from the main air conditioner 100. When the mobile sub-machine 200 needs to refrigerate the outside air in a state that the mobile sub-machine 200 is separated from the air-conditioning main machine 100, the temperature of the heat of the indoor heat exchanger 220 is continuously exchanged with the air introduced from the outside of the mobile sub-machine 200, meanwhile, the energy storage medium continuously absorbs the heat of the energy storage heat exchanger 211 so as to transmit the cold energy stored in the energy storage medium to the energy storage heat exchanger 211, so that the refrigerant in the energy storage heat exchanger 211 is cooled, the cooled refrigerant is continuously transmitted to the indoor heat exchanger 220, the energy storage heat exchanger 211 is connected with the indoor heat exchanger 220, and the refrigerant between the energy storage heat exchanger 211 and the indoor heat exchanger 220 is continuously circulated, so that the temperature of the refrigerant in the indoor heat exchanger 220 is always kept low and continuously exchanges heat with the air, and the mobile sub-machine 200 is enabled to cool the outside air.

When the mobile sub-machine 200 needs to heat the outside air, the indoor heat exchanger 220 continuously exchanges heat with the air introduced from the outside by the mobile sub-machine 200 to reduce the temperature of the air, meanwhile, the energy storage medium transfers the stored heat to the energy storage heat exchanger 211 to heat the refrigerant in the energy storage heat exchanger 211, the energy storage heat exchanger 211 is connected with the indoor heat exchanger 220, the refrigerant between the two continuously circulates, and therefore the temperature of the refrigerant in the indoor heat exchanger 220 is always kept high and continuously exchanges heat with the air, and the temperature of the outside air can be heated by the mobile sub-machine 200.

Therefore, the mobile sub-machine 200 can be separated from the air conditioner main machine 100 to work, the position of the mobile sub-machine 200 can be flexibly adjusted during working, quick heating or cooling can be conveniently carried out on different corners in a room, the temperature in the room can be kept uniform, the position where the user needs to preferentially heat or cool can be conveniently adjusted, and humanized setting of the product during use is improved. In addition, the mobile sub-unit 200 of the present application can also operate in a plurality of rooms, is not limited to its own operating range, nor to the main air conditioner unit 100, and is convenient to use and highly flexible.

It can be understood that, compared with the air conditioner device which is limited by the positions of the exhaust pipe and the outdoor unit and is inconvenient to change the position in the prior art, the air conditioner 1000 of the application has flexible arrangement position and flexible and changeable selectable working position, is beneficial to the rapid and uniform heating and refrigeration of the whole house, and can also process the air in different spaces. Compare and need be equipped with a set of air conditioner respectively in every room among the prior art, the air conditioner 1000 of this application practices thrift the input cost, and the operating position adjustment is convenient to have certain sustainable working property in certain space, product experience is good. Compared with the mobile air-conditioning products in the prior art, the air conditioner 1000 is divided into the air-conditioning main machine 100 and the mobile sub-machine 200, the mobile sub-machine 200 occupies less space when moving, is flexible to move, and has better working durability.

Optionally, the energy storage medium may be an ice-water mixture, and may also be a glycol solution, which is not specifically limited herein and may be selected according to actual needs.

In some embodiments of the present invention, as shown in fig. 4, the mobile sub-machine 200 further comprises a three-way valve 240, and as shown in fig. 3 and 4, the three-way valve 240 connects the energy supplying heat exchanger 120 and the energy storing heat exchanger 211 in a state of being installed in place. As shown in fig. 4 and 8, in the separated state, the three-way valve 240 communicates the indoor heat exchanger 220 and the accumulator heat exchanger 211. In this application, the three-way valve 240 may rapidly switch the circulation flow path of the refrigerant, so as to realize selection of different refrigerant circulation flow paths and realize different heat exchange modes. The cold medium carrying cold or heat is transmitted from the air conditioner main machine 100 to the mobile sub-machine 200 in the state that the mobile sub-machine 200 and the air conditioner main machine 100 are installed in place; and in a state that the mobile sub-unit 200 is separated from the air conditioner main unit 100, the cooling capacity or the heat capacity is gradually transferred from the energy storage device 210 to the indoor heat exchanger 220, thereby completing the heating or cooling of the air in the room by the mobile sub-unit 200.

The three-way valve 240 has three flow channels, and in a specific case, the three flow channels of the three-way valve 240 are respectively communicated with the energy storage heat exchanger 211, the indoor heat exchanger 220 and the energy supply heat exchanger 120 through pipelines, so that the refrigerant flow among the three heat exchangers is switched. When the energy storage heat exchanger 211 is communicated with the indoor heat exchanger 220, the three-way valve 240 cuts off the refrigerant of the flow path of the energy supply heat exchanger 120; when the energy storage heat exchanger 211 is communicated with the energy supply heat exchanger 120, the three-way valve 240 cuts off a flow path between the three-way valve and the indoor heat exchanger 220, so that the refrigerant can be effectively prevented from flowing to an incorrect position and the normal work of the mobile sub-machine 200 can not be realized, and the mobile sub-machine 200 can be ensured to be successfully cooled and heated by the air conditioner main machine 100 under the state that the mobile sub-machine 200 is installed in place with the air conditioner main machine 100; the energy storage device 210 in the mobile handset 100 can normally cool and release heat to the indoor heat exchanger 220 while the mobile handset 200 is separated from the air conditioner main unit 100.

Correspondingly, as shown in fig. 6 and 8, the mobile sub-machine 200 further includes a second pair of joints 320, the second pair of joints 320 is communicated with the energy storage heat exchanger 211, and in a separated state, the second pair of joints 320 is cut off; in the state of being installed in place, the second pair of joints 320 is butted and conducted with the first pair of joints 310, that is, when the second pair of joints 320 is conducted with the first pair of joints 310 in a matching manner, the refrigerant can be controlled to smoothly circulate in the state of being installed in place between the main air conditioner 100 and the mobile sub-machine 200; the second pair of connectors 320 can also control the refrigerant in the energy storage heat exchanger 211 to stop and not overflow outwards when the air conditioner main unit 100 and the mobile sub unit 200 are in a separated state, thereby providing possibility for the quick butt joint of the mobile sub unit 200 and the air conditioner main unit 100, also enabling the cold charging quantity or the heat charging quantity of the mobile sub unit 200 to be more convenient and faster, and enabling the refrigerant in the energy storage heat exchanger 211 not to spill outwards.

Optionally, the first pair of connectors 310 and the second pair of connectors 320 in this application may adopt a combination of a male quick connector and a female quick connector existing in the market, and the structure of the male quick connector and the structure of the female quick connector are not described herein again.

Of course, the first pair of connectors 310 and the second pair of connectors 320 in the present invention are not limited to the aforementioned male quick connector and female quick connector, but a first pair of connectors 310 and a second pair of connectors 320 with specific structures are adopted, which are described in detail as follows:

as shown in fig. 14 and 15, the first butt joint 310 includes a first valve body 311 and a first valve spool 312. As shown in fig. 15 and 16, 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 and 9, the second pair of joints 320 includes a second valve body 321 and a second valve spool 322, and as shown in fig. 8 and 16, the second valve body 321 has a second flow path 3211 and a second pair of ports 3212, and the second valve spool 322 is movably disposed in the second flow path 3211 to block or block the second flow path 3211.

The first pair of joints 310 and the second pair of joints 320 are separably matched, when the first pair of joints 310 and the second pair of joints 320 are matched in place, the first valve core 312 and the second valve core 322 are abutted to enable the first flow channel 3111 and the second flow channel 3211 to be respectively communicated, and when the first pair of joints 310 and the second pair of joints 320 are separated from being matched, the first flow channel 3111 and the second flow channel 3211 are respectively cut off. That is, when the air-conditioning main unit 100 and the mobile sub-unit 200 are in the state of being mounted in place, the first pair of joints 310 and the second pair of joints 320 are fitted in place; when the main air conditioner 100 and the mobile sub-machine 200 are separated, the first pair of connectors 310 and the second pair of connectors 320 are disengaged, at this time, the first pair of connectors 310 effectively cut off the refrigerant in the energy supply heat exchanger 120, and the second pair of connectors 320 effectively cut off the refrigerant in the energy storage heat exchanger 211. As can be seen from the above, the first pair of connectors 310 and the second pair of connectors 320 of the present application are not only convenient and fast to butt, but also enable the refrigerant to be reliably transferred between the main air conditioner 100 and the mobile sub-machine 200; and the first pair of joints 310 can also reliably prevent the refrigerant in the energy supply heat exchanger 120 from spilling outwards, and the second pair of joints 320 can effectively prevent the refrigerant in the energy storage heat exchanger 211 from spilling outwards.

Optionally, as shown in fig. 14 and 15, the first pair of joints 310 further includes a trigger 313; as shown in fig. 8 and 9, the second pair of joints 320 further includes a limit component 323 disposed on the second valve body 321, wherein the limit component 323 is switchable between a stop state and a trigger state, in the stop state, the limit component 323 stops the second pair of ports 3212, the limit component 323 is switched to the trigger state under the trigger of the trigger 313, and in the trigger state, the limit component 323 avoids the second pair of ports 3212 to abut against the first valve element 312 and the second valve element 322. 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. And in the state that the mobile sub-machine 200 is separated from the air-conditioning 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, the limiting component 323 includes a limiting piece 3231 and a connecting member 3232, the limiting piece 3231 is movably disposed on the second valve body 321 through the connecting member 3232, in the stopping state, the limiting piece 3231 shields the second pair of interfaces 3212, and in the triggering state, the limiting piece 3231 avoids the second pair of interfaces 3212, where the second connecting member 3232 enables the limiting piece 3231 to move not only in one direction but also in multiple directions. 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.

Optionally, as shown in fig. 9, 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, 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.

Alternatively, as shown in fig. 9, the limiting plate 3231 has an L-shaped cross section, and includes a stopping plate stopping at the second pair of ports 3212 and a connecting plate capable of disposing a second elastic element 3234, where the stopping plate and the connecting plate are connected at a right angle, so that when the limiting plate 3231 is triggered, the second elastic element 3234 contracts relative to the second valve body 321, and the communication port 3231a on the stopping plate further faces the second pair of ports 3212. 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.

Advantageously, the left side and the right side of the stopping sheet are parallel, the second valve body 321 is provided with guide blocks at intervals in pairs, a guide space is formed between the guide blocks, when the limiting sheet 3231 moves in the radial direction relative to the second valve body 321, the two sides of the stopping sheet contact with the guide blocks and form a guide, and the stability of the limiting sheet 3231 in switching states is greatly improved.

Optionally, the first and second

resilient members

3233, 3234 of the present application are both springs. The form of the spring can be selected according to actual needs.

Alternatively, as shown in fig. 14 and 15, 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.

Advantageously, the rib is a sealing ring sleeved outside the butt joint pipe of the first valve body, the diameter of the sealing ring is larger than the outer diameter of the butt joint pipe, and the inner diameter of the butt joint pipe is larger than or equal to the outer diameter of the first valve core 312, then in a specific example, when the sealing ring contacts the communication port 3231a of the stopper 3231, the stopper 3231 is pushed towards the radial direction, so that the second elastic member 3234 is compressed, and the communication port 3231a of the stopper 3231 further faces the second butt joint port 3212, and at the same time, the first valve core 312 and the first valve body 311 further move towards the second butt joint port 3212, so that the stopper 3231 moves axially relative to the second valve body 321, and the first valve core 312 and the second valve core 322 form a complete butt joint in the axial direction, so as to implement the butt joint and force application process between the two, and further enable the first flow channel 3111 and the second flow channel 3211 to be conducted. On the contrary, when the first pair of joints 310 moves in the direction away from the second pair of joints 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 stop 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.

The fixing bracket 3141 facilitates fixing the first pair of connectors 310 at corresponding positions of the main air conditioner 100.

Referring again to fig. 14, the first valve spool 312 extends out of the first pair of ports 3112 shown in fig. 15; as shown in fig. 15 and 16, when the first notch 3122 is located at the first stop channel 3111a, the first channel 3111 is stopped; as shown in fig. 15 and 18, the first notch 3122 is located in the first communicating cavity 3111b, and the first flow passage 3111 is communicated. 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.

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.

Optionally, the third elastic member 316 and the fourth elastic member 326 are both springs.
