The ice making assembly 200 serves at least to supply ice cubes to the receiving space 110.

As shown in fig. 1, the cold storage assembly 300 includes a condenser 310, an evaporator 320, a throttling element 330, and a compressor 340, the evaporator 320 includes a first evaporation stage 321 and a second evaporation stage 322, the first evaporation stage 321 is provided to the ice making assembly 200 for making ice of the ice making assembly 200, and the second evaporation stage 322 is provided in the receiving space 110.

As shown in fig. 1, the cooling assembly 400 includes a cooling heat exchanger 410, a cooling heat exchanger 420, and a first circulation pump 430, wherein the cooling heat exchanger 410 is disposed in the accommodating space 110, and the first circulation pump 430 is connected between the cooling heat exchanger 410 and the cooling heat exchanger 420.

As can be seen from the above structure, in the air conditioner 1000 according to the embodiment of the invention, by arranging the cold storage box 100 and forming the accommodating space 110 in the cold storage box 100, the accommodating space 110 provides an installation space for arranging the second evaporation section 322 and the cold-taking heat exchanger 410 in the following manner, so that the structures such as the second evaporation section 322 and the cold-taking heat exchanger 410 can be smoothly arranged in the cold storage box 100. In this way, during the use of the air conditioner 1000, at night or when the user temporarily uses the air conditioner 1000, the cold accumulation assembly 300 and the cold accumulation box 100 can be used for carrying out cold accumulation work, after cold accumulation is completed, when the user uses the air conditioner 1000 to refrigerate, the cold release assembly 400 and the cold accumulation box 100 can be used for carrying out cold release work in a matched manner, so that the user requirement is met, in addition, the cold accumulation before cold release process is carried out, and the cost of using the air conditioner 1000 by the user is greatly reduced while the quality of the air conditioner 1000 is improved.

Through setting up the ice-making subassembly 200 that provides the ice-cube towards accommodation space 110, carry the ice-cube to accommodation space 110 in after, the ice-cube is used for reducing the temperature in the accommodation space 110, accomplishes partial cold-storage work, when air conditioner 1000 is cold, can realize refrigeration effect through getting cold heat exchanger 410 of putting cold subassembly 400 and the temperature heat transfer in the accommodation space 110 like this.

By providing the cold storage assembly 300 composed of the condenser 310, the evaporator 320, the throttling element 330 and the compressor 340, when the air conditioner 1000 is turned on at night or when a user temporarily uses the air conditioner 1000, the compressor 340 starts to operate in the cold storage mode, so that the refrigerant medium circularly flows among the compressor 340, the condenser 310, the throttling element 330 and the evaporator 320, wherein the evaporator 320 can continuously cool the temperature in the cold storage tank 100, and the cold storage operation is completed.

It should be noted that, in the cold storage cycle, the evaporator 320 of the present application is formed by two parts of the first evaporation section 321 and the second evaporation section 322, and the first evaporation section 321 exchanges heat with the ice making assembly 200 to reduce the temperature of the ice making assembly 200, so that ice cubes are formed on the ice making assembly 200, and are transported into the accommodating space 110 to reduce the temperature in the accommodating space 110; subsequently, the second evaporation stage 322 exchanges heat with the temperature inside the accommodating space 110 to further reduce the temperature inside the accommodating space 110. That is, the present application can reduce the accommodating space 110 by providing the first evaporation section 321 and the second evaporation section 322, and the first evaporation section 321 and the second evaporation section 322 cooperate, thereby improving the cold storage efficiency in the accommodating space 110.

In some examples, a cold storage medium (such as water) is disposed on the ice making assembly 200 and in the accommodating space 110, and when the first evaporation section 321 exchanges heat with the ice making assembly 200, the first evaporation section 321 is used for changing the water on the ice making assembly 200 into ice so as to make ice on the ice making assembly 200, and then the ice cubes are conveyed into the accommodating space 110 to achieve the purpose of cold storage in the accommodating space 110; when the second evaporation section 322 exchanges heat with the temperature in the accommodating space 110, the second evaporation section 322 is used for changing the water phase in the accommodating space 110 into ice, so as to achieve the purpose of directly making ice in the accommodating space 110, thereby completing cold accumulation work.

By disposing the second evaporation section 322 in the accommodating space 110, the evaporation temperature is controlled below the freezing point of water (typically-15 ℃ to-5 ℃), and as the circulation process proceeds, the second evaporation section 322 continuously cools the cold storage tank 100 until the water in the cold storage tank 100 is completely frozen.

From the foregoing, during the cold storage mode of the present application, the first evaporation section 321 and the second evaporation section 322 exchange heat simultaneously to complete the ice making operation, so as to maximally improve the cold storage efficiency, so as to shorten the cold storage time of the air conditioner 1000, thereby reducing the use cost of the air conditioner 1000, and the cooperation of the first evaporation section 321 and the second evaporation section 322 can also improve the cold storage quality, so that when utilizing ice cubes for refrigeration, the refrigeration quality can be improved, and the user experience is improved.

By arranging the cooling assembly 400 comprising the cooling heat exchanger 410, the cooling heat exchanger 420 and the first circulating pump 430, when the user needs to cool the air conditioner 1000, the air conditioner 1000 starts the cooling mode, and in the cooling mode, the first circulating pump 430 starts to work, so that the cooling medium circularly flows between the cooling heat exchanger 410 and the cooling heat exchanger 420, when the cooling medium circulates to the cooling heat exchanger 410, the cooling medium is used for exchanging heat with the temperature in the accommodating space 110 because the cooling heat exchanger 410 is arranged in the accommodating space 110, so as to reduce the temperature of the cooling medium, and then flows to the cooling heat exchanger 420 under the action of the first circulating pump 430 and exchanges heat with the external air, so that the cooling capacity is released, and the cooling effect is achieved.

The cold accumulation mode and the cold release mode are mutually independent and are continuously and alternately carried out according to the cycle of cold accumulation, cold release and cold accumulation, so that the air conditioner 1000 can be ensured to run safely and stably.

It can be appreciated that compared to the prior art, the air conditioner 1000 of the present application performs the cold storage operation by using the first evaporation section 321 and the second evaporation section 322 simultaneously, so as to maximally improve the cold storage efficiency of the air conditioner 1000.

Optionally, as shown in fig. 1, the inlet of the cold-taking heat exchanger 410 is communicated with the outlet of the cold-releasing heat exchanger 420, the outlet of the cold-taking heat exchanger 410 is communicated with the inlet of the cold-releasing heat exchanger 420, and the first circulating pump 430 is connected between the cold-taking heat exchanger 410 and the cold-releasing heat exchanger 420, so as to form a cold-releasing circulating loop for circulating the cold-carrying medium, so that the purpose of refrigeration is facilitated. The cooling medium can be glycol solution, the glycol solution is not frozen below 0 ℃ and the heat exchange efficiency of the glycol solution is high, so that the refrigerating effect is improved.

It should be emphasized that, this application is through setting up partial structure (first evaporation section 321) of evaporimeter 320 on making ice subassembly 200, set up another partial structure (second evaporation section 322) of evaporimeter 320 in holding chamber 110, when realizing making ice on making ice subassembly 200 and improving cold-storage efficiency, still can avoid all structures with the evaporimeter 320 all setting up in accommodation space 110, can effectively avoid cold-storage box 100 in the phenomenon of appearance local cry like this, thereby avoid putting glycol solution in the cold circulation loop and be frozen, use when influencing the refrigeration.

In some examples, the cold storage tank 100 forms an internally hollow structure so as to form the receiving space 110 within the cold storage tank 100.

Optionally, as shown in fig. 1, the air conditioner 1000 further includes a fan assembly 600, and the fan assembly 600, the condenser 310, and the heat rejection heat exchanger 420 are directly opposite. The fan assembly 600 can simultaneously drive the air flow to exchange heat with the condenser 310 and the cooling heat exchanger 420 respectively in the rotating process, so that the number of the fan assemblies 600 is reduced, the cost of the air conditioner 1000 is reduced, and the structure of the air conditioner 1000 is simple.

Optionally, the condenser 310 and the heat-releasing exchanger 420 are oppositely arranged, the fan assembly 600 is arranged at the lower parts of the condenser 310 and the heat-releasing exchanger 420, when the air conditioner 1000 is in a cool-releasing mode, the fan assembly 600 drives ambient air to generate air flow, and the air flow and the heat-releasing exchanger 420 indirectly exchange heat so as to realize the discharge of cold air flow to the indoor space and realize the refrigeration of the indoor space; when the air conditioner 1000 is in the cold storage mode, the fan assembly 600 drives ambient air to generate air flow, and the air flow and the condenser 310 indirectly exchange heat, so that cooling of the refrigeration medium is realized, and the cold storage stability and the cold storage efficiency of the cold storage assembly 300 are improved.

In the description of the present invention, a feature defining "first", "second" may explicitly or implicitly include one or more of such feature for distinguishing between the described features, no sequential or light weight fraction.

In some embodiments of the invention, as shown in FIG. 1, the first evaporator section 321 communicates upstream of the second evaporator section 322 in the flow path from the throttling element 330 to the compressor 340. Here, upstream means that during the flow of the refrigerant, the refrigerant flows to the first evaporation section 321 to exchange heat with the ice making assembly 200, and then flows to the second evaporation section 322 to exchange heat with the temperature in the accommodating space 110, so that the refrigerant in the first evaporation section 321 is lower than the refrigerant in the second evaporation section 322, thereby improving the heat exchange efficiency of the first evaporation section 321 and ensuring that ice can be made on the ice making assembly 200 effectively.

In addition, since the first evaporation section 321 is disposed on the ice making assembly 200, and the second evaporation section 322 is disposed in the accommodating space 110, the relative positions of the ice making assembly 200 and the cold accumulation box 100 can be further rationally disposed by disposing the first evaporation section 321 upstream of the second evaporation section 322, so that the ice cubes on the ice making assembly 200 can be ensured and can be effectively transported into the accommodating space 110.

Of course, in other examples, the first evaporation section 321 may also be connected downstream of the second evaporation section 322, where the ice making assembly 200 and the cold storage box 100 may be connected through a pipeline, so as to ensure that ice cubes generated on the ice making assembly 200 can be smoothly transported into the accommodating space 110.

In some embodiments of the invention, the evaporator 320 has a flow path length that is greater than the flow path length of the cold-taking heat exchanger 410. The evaporator 320 having a long flow path can sufficiently utilize the refrigerant to exchange heat with water in the ice making assembly 200 or the receiving space, thereby improving the cold storage efficiency.

It should be noted that, because the cooling medium disposed in the cooling heat exchanger 410 is a glycol solution, the glycol solution has excellent heat exchange efficiency, so that the heat exchange efficiency between the glycol solution and the ice can be effectively achieved by setting the cooling heat exchanger 410 with a certain length, that is, the length of the cooling heat exchanger 410 is not too long, if the length of the flow path of the cooling heat exchanger 410 is too long, the heat exchange efficiency between the glycol solution and the ice is higher, so that the ice in the cold storage tank 100 is exchanged into water in a short time, thereby affecting the refrigeration effect, and the longer length of the cooling heat exchanger 410 also causes higher production cost of the air conditioner 1000.

Alternatively, the flow path length of the second evaporation section 322 is equal to the flow path length of the heat exchanger 410. On the one hand, by the arrangement, the flow path length of the second evaporation section 322 can be effectively controlled, and the phenomenon that the cold storage box 100 is partially and deeply cooled due to the longer flow path length of the second evaporation section 322 is avoided; on the other hand, the second evaporation section 322 and the cold-taking heat exchanger 410 are conveniently formed into one piece, thereby facilitating the cold-taking heat exchanger 410 to take cold and improving the refrigerating efficiency.

In some embodiments of the present invention, as shown in fig. 2, the cold-taking heat exchanger 410 and the second evaporation section 322 are formed as a single piece to construct the heat exchanger assembly 500, and the heat exchanger assembly 500 includes at least one row of heat exchange groups 510, and a first refrigerant flow path 511 and a second refrigerant flow path 512 are respectively arranged in parallel in each row of heat exchange groups 510, the first refrigerant flow path 511 is used for the cold-taking heat exchanger 410, and the second refrigerant flow path 512 is used for the second evaporation section 322. It can be understood that, the first refrigerant flow path 511 is used for flowing a cold-carrying medium, and the second refrigerant flow path 512 is used for flowing a cooling medium, and the cold-taking heat exchanger 410 and the second evaporation section 322 are not commonly used at the same time, so that when the air conditioner 1000 is in the cold storage mode, the cooling medium can exchange heat with water through the second refrigerant flow path 512 to achieve the purpose of cold storage; when the air conditioner 1000 starts the cooling mode, the cold carrier medium can exchange heat with ice through the first refrigerant flow path 511 to achieve the purpose of refrigeration, so that the cooling heat exchanger 410 and the second evaporation section 322 are formed as one piece.

In a specific example, each row of heat exchange groups 510 includes a plurality of heat exchange tubes, an end connection tube 520 and a plurality of fins, the plurality of heat exchange tubes are inserted in the plurality of fins, a flowing cooling medium or refrigerating medium is disposed in the heat exchange tubes, part of the heat exchange tubes are connected through the end connection tube 520 to form a first refrigerant flow path 511, and the other part of the heat exchange tubes are connected through the end connection tube 520 to form a second refrigerant flow path 512.

In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

It should be noted that, in this application, the first refrigerant flow paths 511 and the second refrigerant flow paths 512 are alternately arranged, so that when the heat exchange is performed between the cold carrier medium and ice or between the refrigerant medium and water, each row of heat exchange groups 510 can be used for heat exchange, thereby further avoiding the area waste of the fins.

Alternatively, the heat exchange pipe may be provided as a straight pipe and the end connection pipe 520 may be provided as a bent pipe. The shape of the bent pipe can be set to be arc, the heat exchange pipe can be set to be copper pipe, but the invention is not limited to the arc, the heat exchange pipe can be set to be a pipe with the same function as the copper pipe, for example: the heat exchange tube can also be an aluminum tube, and the end connecting tube 520 can be welded with the heat exchange tube, so that the connection strength between the heat exchange tube and the end connecting tube 520 is improved, and leakage of the cold-carrying medium or the refrigerating medium in the flowing process is avoided.

It should be noted that, through setting up the heat exchange tube into the straight tube, can be convenient for simplify the heat exchange tube structure to be convenient for heat exchange tube and fin assembly, in addition, through setting up the tip connecting pipe 520 into the return bend, can avoid first refrigerant flow path 511 and second refrigerant flow path 512 to take place to interfere, thereby can avoid adjacent tip connecting pipe 520 to hit the bad, prolong the life of tip connecting pipe 520, also make things convenient for tip connecting pipe 520 to be connected with the heat exchange tube simultaneously.

In some embodiments of the present invention, the fins of the heat exchanger assembly 500 are preferably aluminum foil materials, wherein to avoid corrosion of the fins by prolonged immersion in a cold storage medium (e.g., water), an anti-corrosion coating may be provided on the outer surfaces of the fins, so that corrosion of the fins may be delayed or avoided, extending the service life of the fins.

Alternatively, as shown in FIG. 2, heat exchanger assembly 500 includes a plurality of rows of heat exchange groups 510. The multi-row heat exchange group 510 can exchange heat with the cold storage medium in the cold storage box 100 at the same time, so that the heat exchange efficiency of the heat exchanger assembly 500 is further improved, and the cold storage or cold release quality is improved.

Optionally, the first refrigerant flow paths 511 and the second refrigerant flow paths 512 of the two adjacent rows of heat exchange groups 510 are staggered, so as to avoid interference between the first refrigerant flow paths 511 and the second refrigerant flow paths 512.

Alternatively, as shown in fig. 2, the first refrigerant flow paths 511 of adjacent rows of heat exchange groups 510 communicate through a first cross pipe 530. The first refrigerant flow paths 511 of the heat exchange groups 510 of adjacent rows are communicated through the first cross-pipe member 530, so that the cold-carrying medium is simultaneously loaded in each row of heat exchange groups 510, the cold-carrying medium flows in the plurality of rows of heat exchange groups 510, the cold-carrying medium in the plurality of rows of heat exchange groups 510 exchanges heat with the cold-storage medium simultaneously, and the heat exchange efficiency is improved, so that the refrigerating efficiency of the air conditioner 1000 is improved.

Optionally, as shown in fig. 2, the second refrigerant flow paths 512 of the adjacent rows of heat exchange groups 510 are in communication through a second cross pipe 540. Through the communication of the second refrigerant flow paths 512 of the heat exchange groups 510 of the adjacent rows through the second pipe spanning member 540, the refrigerant medium can be simultaneously present in each row of heat exchange groups 510, so that the refrigerant medium flows in the plurality of rows of heat exchange groups 510, and the refrigerant medium in the plurality of rows of heat exchange groups 510 exchanges heat with the cold storage medium simultaneously, thereby improving the heat exchange efficiency and the cold storage efficiency of the air conditioner 1000.

Optionally, the shape of the first cross-tube 530 is the same as the shape of the second cross-tube 540. The arrangement can simplify the structure of the first span pipe fitting 530 and the second span pipe fitting 540, can facilitate the production and manufacture of the first span pipe fitting 530 and the second span pipe fitting 540, can realize the production of the first span pipe fitting 530 and the second span pipe fitting 540 by using one set or one die, can reduce the development of the die for producing the first span pipe fitting 530 and the second span pipe fitting 540, and can reduce the production cost of the first span pipe fitting 530 and the second span pipe fitting 540.

Optionally, two adjacent rows of heat exchange groups 510 are spaced apart to define a flow space. The cold storage medium can be ensured to be arranged in the flowing space between two adjacent rows of heat exchange groups 510, so that the heat exchange area of the heat exchanger assembly 500 and the cold storage medium can be increased, the heat exchange between the cold storage medium and the heat exchanger assembly 500 can be uniform, and the temperature difference of each area of the cold storage medium can be reduced.

In some embodiments of the present invention, as shown in fig. 1, the ice making assembly 200 includes an ice making member 220, and the first evaporation section 321 acts on the ice making member 220 to make ice of the ice making member 220. That is, the ice making work of the ice making assembly 200 of the present application is mainly performed on the ice making member 220, and the ice cubes are conveniently transferred toward the inside of the receiving space 100 to accomplish the cold storage effect.

Alternatively, the ice making member 220 is positioned above the receiving space 110, and the top of the receiving space 110 is opened to receive the liquid and the ice cubes falling from the ice making member 220. So set up, the ice-cube that forms on making ice piece 220 under the effect of gravity can drop in accommodation space 110, need not to set up the transmission piece of transmission ice-cube between making ice piece 220 and accommodation space 110 to make the simple structure of air conditioner 1000, and reduce the manufacturing cost of air conditioner 1000.

Alternatively, the first evaporator section 321 is configured as a coil heat exchanger that is snugly connected to the ice making member 220. The coiled heat exchanger is used for increasing the length of the first evaporation section 321, so that the first evaporation section 321 is connected to the ice making member 220, and the contact area between the first evaporation section 321 and the ice making member 220 can be increased, thereby improving the heat exchange efficiency and being more beneficial to forming ice cubes on the ice making member 220.

The bonding connection may be that the first evaporation section 321 is adhered to the ice making member 220, or may be that the bonding connection is made by an external connection member through a connection manner such as a snap connection or a plug connection, to the ice making member 220. The specific connection mode of the first evaporation section 321 and the ice making piece 220 is not limited, so long as the first evaporation section 321 is ensured to be stably connected to the ice making piece 220.

Optionally, as shown in fig. 1, the ice making assembly 200 further includes a spraying unit 230 and a second circulation pump 240, the spraying unit 230 is used for spraying liquid to the ice making member 220, the second circulation pump 240 is communicated with the receiving space 110, the second circulation pump 240 is communicated with the spraying unit 230, and the second circulation pump 240 is used for pumping liquid in the receiving space 110 and supplying the spraying unit 230. That is, the second circulation pump 240 is simultaneously connected to the spraying unit 230 and the accommodating space 110, and the second circulation pump 240 is used for pumping the liquid in the accommodating space 110 and delivering the liquid to the spraying unit 230, and then the spraying unit 230 sprays the liquid onto the ice making member 220 to achieve the purpose of delivering the liquid in the cold storage tank 100 to the ice making member 220, wherein the liquid is the cold storage medium (water).

Optionally, after the spraying unit 230 sprays the liquid onto the ice making member 220, the first evaporation section 321 exchanges heat with the ice making member 220 to change the liquid on the ice making member 220 into ice, and then the ice making member 220 conveys the ice cubes into the cold storage tank 100, and the above-mentioned circulation process is repeated to realize that the liquid stored in the cold storage tank 100 is changed into ice, thereby completing the cold storage operation of the air conditioner 1000.

In addition, since the ice making member 220 is disposed at the upper portion of the cold storage tank 100 and the top of the cold storage tank 100 is opened, part of the liquid may be sprayed into the cold storage tank 100 during the spraying of the liquid toward the ice making member 220 by the spraying unit 230 to accelerate the flow of the liquid, reduce the temperature difference inside the cold storage tank 100, and increase the cold storage speed.

It should be noted that, when the water in the cold storage tank 100 is conveyed by the second circulation pump 240 and flows toward the ice making member 220, the second evaporation section 322 located in the cold storage tank 100 operates synchronously to directly change part of the water in the cold storage tank 100 into ice, that is, the water in the cold storage tank 100 of the present application can change into ice in two ways (the first way is that the ice making assembly 200 cooperates with the first evaporation section 321 to make ice, the second way is that the ice is directly made by the second evaporation section 322), and the two ways operate synchronously to make ice, so as to improve the ice making efficiency, that is, improve the refrigerating efficiency of the air conditioner 1000.

Optionally, the second circulation pump 240 is connected to the accommodating space 110 and the second circulation pump 240 is connected to the spraying unit 230 through pipes, so as to facilitate the transportation of the cold storage medium.

In the first aspect, the second circulation pump 240 may be directly placed in the cold storage tank 100 without providing an extra connection pipeline, so that the structure of the air conditioner 1000 is simple; in the second aspect, the side wall of the cold accumulation tank 100 may function to protect the second circulation pump 240 to extend the service life of the second circulation pump 240; in the third aspect, the cold storage medium at the bottom of the accommodating space 110 may also be delivered to the ice making member 220 by the second circulation pump 240, so that water in the cold storage tank 100 may be phase-changed into ice to improve the cold storage quality.

Optionally, the ice making assembly 200 further includes a detector for detecting the ice making degree of the ice making member 220. Thereby accurately acquiring the freezing degree of the liquid on the ice making member 220.

Advantageously, the detector is a thickness sensor, and the thickness sensor is used for detecting the thickness of the ice cubes on the ice making member 220 in real time, and when the thickness of the ice cubes reaches a certain value, the ice making member 220 is heated by the heating member below, so as to ensure that the ice cubes on the ice making member 220 can fall into the cold storage box 100.

It should be noted that, when the thickness of the ice making member 220 is thicker, the water conveyed by the second circulation pump 240 toward the ice making member 220 directly drops onto the ice cubes, so that the water cannot directly exchange heat with the first evaporation section 321, and the ice making efficiency of the ice making member 220 is further reduced. Therefore, the thickness of the ice blocks is detected in real time by the detector, and after the thickness of the ice blocks reaches a certain value, the ice blocks fall off, so that the ice can be made on the ice making piece 220 again, and the ice making quality is improved.

Of course, in other examples, the detector may also be a trigger sensor, when the ice cubes reach a certain height, the ice cubes mechanically collide with the trigger sensor, and after the trigger sensor is triggered, the ice making member 220 is heated by the heating member below, so as to ensure that the ice cubes on the ice making member 220 can fall into the cold storage box 100.

Optionally, the ice-making assembly 200 further includes a heating member for heating the ice-making member 220 to melt ice cubes attached to the ice-making member 220 to be detached. Because the ice-making member 220 is disposed at the upper portion of the cold storage tank 100, after ice cubes are melted, they drop in a direction toward the cold storage tank 100 by gravity, thereby realizing the transportation of ice cubes toward the inside of the cold storage tank 100.

It should be noted that, the fact that the heating element melts the ice cubes attached to the ice making element 220 means that at least one side surface of the ice cubes is attached to the ice making element 220 in the process of making ice by the ice making element 220, the attached area is melted by the heating element, and the ice cubes can be discharged into the cold storage box 100 under the action of gravity, so that the ice cubes on the ice making element 220 fall off.

Optionally, the heating element is specifically an electric heating wire, the electric heating wire is connected to the ice making element 220, and when the detector detects that the thickness of the ice cubes on the ice making element 220 reaches a certain value, the electric heating wire is electrified and started to heat the ice making element 220, so that one side surface of the ice cubes, which is close to the ice making element 220, is promoted to melt, and the ice cubes fall off.

Advantageously, the vibration motor or the ice throwing mechanism is arranged on the ice making piece 220, when the ice removing operation is needed, the vibration motor drives the ice making piece 220 to shake or the ice throwing mechanism pushes ice cubes in the ice making piece 220, so that the ice cubes are easier to fall off, the ice removing efficiency is improved, the quick ice removing is realized, and the air conditioner 1000 can enter the cooling mode more quickly, and the user experience is improved.

Optionally, the air conditioner 1000 further includes a first sensor disposed in the cold storage tank 100, the first sensor being for detecting the height of ice cubes in the cold storage tank 100. Thus, whether the cold accumulation in the cold accumulation box 100 is completed is detected in real time, that is, when the user starts the air conditioner 1000 to perform refrigeration, whether the air conditioner 1000 can be switched to the cold release mode can be judged according to the data detected by the first sensor.

The water in the cold storage tank 100 is supplied to the ice making member 220, the generated ice cubes fall into the cold storage tank 100, after a certain period of time, the liquid level in the cold storage tank 100 decreases, the accumulation amount of the ice cubes gradually increases, and the ice cubes float above the water surface, so that the first sensor can be configured as a liquid level sensor, and by detecting the change of the liquid level in the cold storage tank 100, whether the cold amount in the cold storage tank 100 meets the requirement of switching to the cold release mode can be correspondingly identified, and when the requirement is met, the cold release mode is switched to the cold release mode; or the first sensor is configured as a height sensor, the stacking height of the ice cubes is detected by the height sensor, and the stacking height of the ice cubes in the cold storage box 100 is detected to correspondingly identify whether the cold amount in the cold storage box 100 meets the requirement of switching to the cold release mode or not, and when the requirement is met, the cold storage box is switched to the cold release mode.

Advantageously, the first sensor is configured as a height sensor, and the embodiment of identifying whether the cooling capacity meets the cooling requirement by detecting the stacking height of the ice cubes is more intuitive, wherein the air conditioner 1000 can be switched to the cooling mode according to the user requirement when the first sensor detects that the stacking height of the ice cubes reaches the preset threshold.

In other examples, the air conditioner 1000 further includes a second sensor disposed within the cold storage tank 100 for detecting a temperature of the cold storage medium within the cold storage tank 100.

Alternatively, the second sensor may be configured as a temperature sensor.

Whether the air conditioner 1000 is switched from the cold accumulation mode to the cold discharge mode is determined by the first sensor, whether the air conditioner 1000 is switched from the cold discharge mode to the cold accumulation mode is determined by the second sensor, and because the cold-carrying medium in the cold-taking heat exchanger 410 exchanges heat with ice blocks in the cold discharge mode, the ice blocks melt, and when the temperature of the cold accumulation medium is higher than the temperature threshold value, the shortage of cold in the cold accumulation box 100 is indicated, and at the moment, the air conditioner 1000 needs to be switched to the cold accumulation mode to perform cold accumulation again, so that the air conditioner 1000 is switched between the cold accumulation mode and the cold discharge mode.

In some embodiments, the air conditioner 1000 may be directly controlled to switch to the cold storage mode when the temperature signal collected by the temperature sensor is higher than the temperature threshold, and in other embodiments, the air conditioner 1000 may send a cold shortage prompt when the temperature signal collected by the temperature sensor is higher than the temperature threshold, and may switch to the cold storage mode under the control of the user.

Of course, the timing can also be performed after the indication of insufficient cooling capacity is sent, if the user controls the air conditioner, the air conditioner is directly switched to the cold accumulation mode or stopped in the timing period, and when the user does not give the opposite control instruction after the timing period is exceeded, the air conditioner is automatically controlled to be switched to the cold accumulation mode, so that the use experience of the air conditioner 1000 is improved.

Alternatively, the ice making assembly 200 is disposed outside the cold box 100. The ice making assembly 200 is ensured not to occupy the inner space of the cold storage box 100, so that cold storage media can be stored in the cold storage box 100 to the greatest extent, the use during subsequent cold release is facilitated, the refrigeration quality of the air conditioner 1000 is improved, the single refrigeration duration of the air conditioner 1000 is prolonged, and the user experience is improved.
