In other words, the lower surfaces of the first ice making grid 41 and the second ice making grid 42 are easily attached to the lower surface of the ice block, so that the ice block cannot be separated, and correspondingly, an electric auxiliary heating element can be arranged on the lower surfaces of the first ice making grid 41 and the second ice making grid 42, when the ice removing operation is required (i.e. the cold storage air conditioner 100 is switched to the ice removing mode), the electric auxiliary heating element heats the first ice making grid 41 or the second ice making grid 42, and the ice block drops to the cold storage box 11 or the ice box 12 after melting, so that the same technical effect as that of arranging the bypass valve can be achieved, and the details are omitted.

It will be appreciated that, in order to facilitate the ice to fall off, the first ice making tray 41 and the second ice making tray 42 may be obliquely arranged, and the first ice making tray 41 and the second ice making tray 42 may each include: the bottom plate and the side plates, the first ice making grid 41 and the second ice making grid 42 are arranged in an inclined way, namely, the bottom plate has a certain angle relative to the horizontal plane, the inclined angle can be 3 degrees to 30 degrees, and the first evaporator 53 or the second evaporator 54 can be arranged between the bottom plate and the side plates; or the first evaporator 53 and the second evaporator 54 are both configured as micro-channel heat exchangers, and are correspondingly embedded in the bottom plate or the side plate, and in the embodiment in which the ice melting piece 70 is configured as an electric auxiliary heating piece, the electric auxiliary heating piece is correspondingly arranged on one side of the bottom plate away from the side plate.

It should be noted that, in the process of implementing multiple ice removal by switching the cold storage mode and the ice removal mode, when the ice storage beam in the cold storage tank 11 reaches a certain height, the ice storage mode may be switched to the cold storage mode, or when the temperature in the cold storage tank 11 reaches a certain preset temperature value, the ice storage mode may be switched to the cold storage mode, and when the ice storage beam in the ice box 12 reaches a certain height, the ice storage mode may be exited, which is not specifically limited in this application.

More importantly, during the cold accumulation process of the present application, water in the cold accumulation tank 11 needs to be extracted, and during the cold discharge process, water in the cold accumulation tank 11 needs to be extracted to participate in the cold discharge cycle, and in the ice removal mode, at least partial melting of ice cubes in the first ice making grid 41 can be ensured, so that a certain amount of water is ensured to be always stored in the cold accumulation tank 11, the air suction phenomenon of the first circulating pump 61 can be avoided, and the working stability of the cold accumulation air conditioner 100 can be further improved.

It should be noted that, in the embodiment in which the first cold accumulation loop and the second cold accumulation loop are connected in series, a bypass valve may be provided to implement synchronous ice melting of the first ice making grid 41 and the second ice making grid 42, and in the embodiment in which the first cold accumulation loop and the second cold accumulation loop are connected in parallel, a bypass valve may be provided on a trunk of the cold accumulation loop to implement synchronous ice melting of the first ice making grid 41 and the second ice making grid 42, or a bypass valve (a branch in which the first evaporator 53 and the second evaporator 54 are connected in parallel) may be provided on a branch of the cold accumulation loop to implement ice melting of the first ice making grid 41 and the second ice making grid 42.

In other embodiments, the first ice making grid 41 may be provided with an electric auxiliary heating element, while the second ice making grid 42 is subjected to ice melting through a bypass valve, or the first ice making grid 41 is subjected to ice melting through a bypass valve, and the first ice making grid 41 is provided with an electric auxiliary heating element; meanwhile, in order to accelerate the ice removing efficiency, the electric auxiliary heating element and the bypass valve can synchronously act to improve the ice melting speed and realize quick ice removing.

As shown in fig. 1, further, the cold storage air conditioner 100 further includes: fan assembly 80, condenser 52, and chiller 22 are directly opposite.

Specifically, the condenser 52 and the radiator 22 may be disposed opposite to each other, and the fan assembly 80 is disposed downstream of the two, so that when the cold storage air conditioner 100 is in the cooling mode, ambient air is driven by the fan assembly 80 to generate an air flow, and the air flow and the radiator 22 indirectly exchange heat, so as to discharge the cold air flow to the indoor space and realize refrigeration of the indoor space; when the cold accumulation air conditioner 100 is in the cold accumulation mode, the fan assembly 80 drives ambient air to generate air flow, and the air flow and the condenser 52 indirectly exchange heat, so that the cooling of the cold accumulation loop is realized, and the refrigeration stability of the cold accumulation loop is improved.

In this way, on the one hand, the fan assembly 80 can dissipate heat of the condenser 52 in the cold storage mode, and in the cold storage mode, the air flow is quickened so as to realize rapid refrigeration of the indoor space, and the condenser 52 and the cold discharger 22 can share an air duct, so that the space occupation of the cold storage air conditioner 100 is further reduced; on the other hand, in the cold mode, heat removal is not needed, and the use experience of a user can be improved.

According to some embodiments of the present application, the cold storage air conditioner 100 further includes: and a first sensor provided on the first ice making tray 41 to detect the thickness of the cold storage medium in which the phase change occurs or the second ice making tray 42 to detect the thickness of the ice cubes.

Specifically, in the switching process of the cool storage mode and the ice removing mode, the cool storage air conditioner 100 needs to switch based on the amount of ice cubes on the first ice making compartment 41, switch to the cooling mode after ice is removed a plurality of times, and further determine the amount of ice cubes on the first ice making compartment 41 based on the thickness of the ice cubes in the first ice making compartment 41, and control the switching to the ice removing mode after the thickness of the ice cubes reaches a certain threshold.

Similarly, in the switching process of the ice making mode and the ice removing mode, the cold storage air conditioner 100 needs to switch based on the amount of ice cubes on the second ice making tray 42, and exit the ice making mode after ice is removed for a plurality of times, so that the amount of ice cubes on the second ice making tray 42 can be determined based on the thickness of the ice cubes in the second ice making tray 42, and after the thickness of the ice cubes reaches a certain threshold, the switching to the ice removing mode is controlled.

In other words, by providing the first sensor, the first sensor may be configured as a position sensor or a trigger sensor, which is triggered when the ice thickness reaches a certain height; or when the ice cubes reach a certain height, the ice cubes mechanically collide with the trigger sensor, and after the first sensor is triggered, the ice melting piece 70 is controlled to work so that the ice cubes fall into the cold storage box 11 or the ice box 12 after the ice cubes are melted on the surface.

The first sensor may be plural, and the plural first sensors are disposed in the first ice making compartment 41 and the second ice making compartment 42, respectively, and in an embodiment in which the first cold storage circuit is connected in series with the second cold storage circuit, when the ice cubes in either the first ice making compartment 41 or the second ice making compartment 42 reach a preset thickness, the cold storage air conditioner 100 is controlled to switch to the ice removing mode, whereas in an embodiment in which the first cold storage circuit is connected in parallel with the second cold storage circuit, if the ice cubes in the first ice making compartment 41 reach a preset thickness, the first cold storage circuit is controlled to switch to the ice removing mode, and if the ice cubes in the second ice making compartment 42 reach a preset thickness, the second cold storage circuit is controlled to switch to the ice removing mode.

In addition, it should be pointed out that after a certain cold accumulation loop is switched to the ice removing mode, the cold accumulation loop does not refrigerate until the ice making grid corresponding to the cold accumulation loop completes ice removing.

It can be understood that the vibration motor or the ice throwing mechanism can be further arranged on the first ice making grid 41 and the second ice making grid 42, when the ice removing operation is needed, the vibration motor drives the first ice making grid 41 and the second ice making grid 42 to shake or the ice throwing mechanism pushes the ice cubes in the first ice making grid 41 and the second ice making grid 42, so that the ice cubes are easier to fall off, the efficiency of the ice removing operation can be improved, the quick ice removing can be realized, and the cold storage air conditioner 100 can enter the cold mode more quickly, and the use experience is improved.

Further, the cold storage air conditioner 100 further includes: the first height sensor is arranged in the cold accumulation box 11 and is used for detecting the height of cold accumulation medium in the cold accumulation box 11, and the second height sensor is arranged in the ice box 12 and is used for detecting the height of ice cubes in the ice box 12.

Specifically, the cold storage air conditioner 100 may be controlled to switch between the cold storage mode and the ice removal mode by the first sensor; or between the ice making mode and the ice removing mode, and by providing the first height sensor, the liquid level height of the water surface in the cold storage tank 11 or the stacking height of the ice cubes can be detected, and when the stacking height or the liquid level height reaches a height threshold or a liquid level threshold, the cold storage air conditioner 100 is controlled to switch to the cold mode.

The water in the cold storage tank 11 is supplied to the first spraying member 31, the generated ice cubes fall into the cold storage tank 11, along with the process of cold storage operation and ice removing operation, the liquid level in the cold storage tank 11 is reduced, the accumulation amount of the ice cubes is gradually increased, and the ice cubes float above the water surface, so that the first height sensor can be configured as a liquid level sensor, by detecting the change of the liquid level in the cold storage tank 11, whether the cold amount in the cold storage tank 11 meets the requirement of switching to the cold mode or not can be correspondingly identified, and when the requirement is met, the cold mode is switched to the cold mode; or the first height sensor detects the stacking height of the ice cubes, and the first height sensor detects the stacking height of the ice cubes in the cold storage box 11 to correspondingly identify whether the cooling capacity in the cold storage box 11 meets the requirement of switching to the cooling mode or not, and when the cooling capacity meets the requirement, the first height sensor switches to the cooling mode.

By providing the second height sensor, the stacking height of ice cubes within the ice bank 12 may be detected and the cold storage air conditioner 100 may be controlled to exit the ice making mode when the stacking height reaches a height threshold.

Wherein, the domestic water is supplied to the second spraying part 32 through the second circulation pump 63, and the generated ice cubes may fall into the ice bin 12, and the amount of the ice cubes stacked in the ice bin 12 may be gradually increased as the ice making and de-icing processes are performed, so that the stacked height of the ice cubes may be detected through the second height sensor, and it may be correspondingly recognized whether the ice cubes stored in the ice bin 12 are sufficient or not through the detection of the stacked height of the ice cubes in the ice bin 12.

It can be appreciated that the implementation of identifying whether the cooling capacity meets the cooling demand by detecting the stacking height of ice cubes is more intuitive, and the first height sensor referred to in the application is used for detecting the height of the cold storage medium in the cold storage tank 11, which may be the liquid level height of the liquid cold storage medium or the stacking height of the solid cold storage medium in the cold storage tank 11.

It should be noted that when the cooling capacity in the cold storage tank 11 reaches a certain threshold (i.e. the liquid level reaches a liquid level threshold; or when the ice height reaches a height threshold), the cold storage air conditioner 100 can be controlled to switch to a cold mode correspondingly, and the corresponding liquid level threshold or height threshold can be different when the user sets different refrigeration temperatures and different working gears, and the lower the refrigeration temperature is, the higher the working gear is, the smaller the corresponding liquid level threshold is; or the greater the height threshold.

In addition, an ice guide channel can be further arranged to enable the ice box 12 to be selectively communicated with the cold accumulation box 11, so that ice cubes in the ice box 12 can be at least partially supplied to the cold accumulation box 11, the working time of the cold accumulation air conditioner 100 in a refrigerating mode can be prolonged, meanwhile, water which is dropped into the ice box 12 in an ice removing mode can be led into the cold accumulation box 11, the quality of the ice cubes in the ice box 12 is improved, the phenomenon of adhesion of the ice cubes in the ice box 12 is avoided, and the use experience can be further improved.

Further, the cold storage air conditioner 100 further includes: and a temperature sensor provided in the cold storage tank 11 for detecting the temperature of the cold storage medium in the cold storage tank 11.

After the cold storage mode and the ice removing mode are switched through the first sensor, the cold storage medium needs to be collected in the cold storage mode after the cold storage mode and the ice removing mode are switched through the second sensor, and when the temperature of the cold storage medium is higher than a temperature threshold value, insufficient cold energy in the cold storage tank 11 can be ensured, and at the moment, the cold storage mode needs to be switched to and the cold storage is performed again, so that the cold storage air conditioner 100 is switched among the cold storage mode, the ice removing mode and the cold storage mode.

It should be noted that, in some embodiments, when the temperature signal collected by the temperature sensor is higher than the temperature threshold, the cold storage air conditioner 100 may be directly controlled to switch to the cold storage mode, and in other embodiments, when the temperature signal collected by the temperature sensor is higher than the temperature threshold, a cold shortage prompt is correspondingly sent, and the cold storage air conditioner may be switched to the cold storage mode under the control of a user. Of course, the timing can also be performed after the indication of insufficient cooling capacity is sent, if the user controls the cold storage mode or the cold storage air conditioner is stopped in the timing period, and when the user does not give the opposite control instruction after the timing period is exceeded, the cold storage air conditioner 100 is automatically controlled to be switched to the cold storage mode, so that the use experience of the cold storage air conditioner is improved.

In some embodiments, the cold storage air conditioner 100 further includes: the housing, the cold accumulation tank 11, the cold release circuit, the first spray member 31, the first ice making tray 41, the cold accumulation circuit, the ice melting member 70, the second spray member 32, and the second ice making tray 42 are all disposed in the housing.

Meanwhile, the first spraying piece 31, the first ice making grid 41 and the cold accumulation box 11 are sequentially arranged in the height direction of the shell, and can be stacked or have a gap; the second shower 32, the second ice making tray 42, and the ice bank 12 are disposed in this order in the height direction of the housing, and may be stacked or may have a gap.

The movable wheels can be arranged below the shell, so that the cold accumulation air conditioner 100 can be transported conveniently, the cold accumulation air conditioner 100 can be formed into a movable air conditioner, and the use experience is further improved.

Further, the housing has an air outlet downstream of the condenser 52 and the radiator 22.

That is, the fan assembly 80, the condenser 52 and the cooler 22 are all disposed upstream of the air outlet, and the fan assembly 80 is disposed most upstream of the air outlet, while the condenser 52 and the cooler 22 are disposed between the fan assembly 80 and the air outlet, and the order of the condenser 52 and the cooler 22 is not particularly limited.
