The cold air generated by the evaporation and heat exchange is discharged to an indoor kitchen for refrigeration and temperature reduction.

The gaseous refrigerant returns to the compressor 1 to continue compression and the cycle continues.

As shown in fig. 2 and 3, the air flow of the evaporator 3 is supplied by the air duct assembly 22, specifically, the first chamber 301 in the main unit 100 is a heat exchange channel, the evaporator 3 is located on the heat exchange channel, so that the first chamber 301 is separated into a front channel 303 and a rear channel 304 which are independent of each other, the air duct assembly 22 is connected to or passes through the heat exchange channel, the air flow passing through the front channel 303 is heat exchanged by the internal evaporator 3, and is discharged by the rear channel 304.

The air duct assembly 22 has an air outlet 6 and a plurality of air inlets 12, the air outlet 6 is disposed at a position of an air outlet of the indoor fan 5, and the position can be connected to the kitchen ceiling 17 through a pipeline.

The air outlet 6 communicates with the first space region, the air inlets 12 communicate with different second space regions, and the plurality of air inlets 12 are illustrated in this embodiment for convenience, and three air inlets 12 are taken as an example to explain the working process of this embodiment. The first space area is exemplified by a kitchen space, and the second space area is exemplified by an indoor living room or bedroom space and an outdoor space.

Specifically, in this embodiment, the first spatial region includes a region with a fast temperature rising rate, and the kitchen includes a region where the cooking bench is located. The overall temperature of the second spatial regions is more uniform, and the average temperature of different second spatial regions is different. Taking the home environment as an example, the second space region is an indoor other space and an outdoor space. Specifically, the air inlet 12 at least includes:

the kitchen air inlet 123 is formed in the kitchen space, and the kitchen air inlet 123 is formed in the kitchen ceiling 17;

the indoor air inlet 121 is formed in other indoor spaces other than the kitchen space, the indoor air inlet 121 is formed in the inner wall 16 of the kitchen and is connected to an adjacent living room or bedroom through the inner wall 16 of the kitchen;

and the outdoor air inlet 122 is arranged in the outdoor space, and the outdoor air inlet 122 can be directly arranged on the outer wall 18 of the kitchen.

The air duct assembly 22 is connected to each of the air inlets 12, and the air duct assembly 22 may be any one of a pipe, an air duct, and a building passageway, and may have a circular or other polygonal cross-sectional shape.

It should be appreciated that the inlet 12 may be located on the main unit 100, or may be located anywhere on the air duct assembly 22, and the air duct assembly 22 is connected to and extends from the inlet 12.

The air inlets 12 are communicated with one side of the front channel 303 of the first chamber 301, air flow in the air inlets 12 exchanges heat through the evaporator 3, the air flow in the front channel 303 is refrigerated and then conveyed to the rear channel 304, and the air flow is discharged into a kitchen room from the air outlet 6 on the kitchen ceiling 17 through the rear channel 304.

The air outlet 6 is arranged on the kitchen ceiling 17 and is arranged at an interval with the kitchen air inlet 123, the kitchen air inlet 123 and the air outlet 6 form continuous air flow on the kitchen ceiling 17, and the air flow path passing through the kitchen space can better discharge oil smoke and hot air, and on the basis of carrying out heat exchange on the air flow, the oil smoke and the smoke are further removed.

As shown in fig. 2 and 3, the evaporator 3 is inclined in the first chamber 301, and specifically, the inclination refers to that the body of the evaporator 3 is inclined, which may be in a horizontal direction when the first chamber 301 is a vertical passage, and may be in a vertical direction when the first chamber 301 is a horizontal passage.

When the evaporator 3 is tilted to the first chamber 301, at least one side of the tilted evaporator 3 may be relatively short or narrow, so that an airflow channel 305 can be formed between the evaporator 3 and the side wall of the main body 100.

Or an airflow channel 305 communicating the front channel 303 and the rear channel 304 is opened at the evaporator 3 near the main unit 100.

Under the condition of arranging a conventional heat exchanger for heat exchange, the grille structure in the evaporator 3 at the position of the airflow channel 305 is less or has no grille structure, the air inlet is relatively less in resistance, the air inlet amount is large, and the air inlet efficiency is further improved.

Specifically, as shown in fig. 3, the evaporator 3 of the present embodiment has the same shape as the evaporator 3 of the prior art, wherein the side wall of the main unit 100 refers to the side wall corresponding to the end of the evaporator 3 in the length direction. Alternatively, on the basis of fig. 3, the length of the evaporator 3 is extended continuously, so that both ends of the evaporator 3 abut against the inner wall of the first chamber 301, and at the same time, the height of the evaporator 3 is reduced, in which case the side wall of the main body 100 refers to the top inner wall of the first chamber 301, and an air flow channel 305 is left between the top of the evaporator 3 and the side wall of the main body 100. In an alternative embodiment, the height of the evaporator 3 is not lower than the height of the indoor air intake 121, the outdoor air intake 122 and the kitchen air intake 123, so that the air flow entering from the three air intakes mostly passes through the evaporator 3, and the rest passes through the air flow channel 305 on the top of the evaporator 3. This solution changes the shape of the evaporator 3, but does not reduce the area of the evaporator 3 for heat exchange by the air flow. The evaporator 3 has a certain wind resistance, and the wind resistance can be effectively reduced after the airflow channel 305 is added, so that the effect of increasing the air intake is improved. Further, for the constant frequency air conditioner, the efficiency of the evaporator 3 itself is fixed, and thus the user feels a cool wind blowing straight. The traditional air conditioner aims at regulating the temperature of the whole room. The temperature distribution of the whole house is lower as the temperature is closer to the floor of the room, the sensible temperature of a user is approximately consistent with the middle temperature of the height of the room, and the traditional air conditioner cannot blow the user directly, so that the temperature of cold air blown out by the air conditioner is lower than the temperature adjusted by the user. In this scheme, the air through airflow channel 305 does not cool through the heat transfer of evaporimeter 3, blows out after mixing with the lower air current of the temperature after the cooling, forms the cool wind that is mild relatively, and the direct-blowing user body that cools down also can not feel uncomfortable. In this embodiment, air outlet 6 is located the kitchen furred ceiling, and air outlet 6 sets up towards the top of a kitchen range region, can be to the regional output air conditioning of top of a kitchen range, reduces the temperature in the region of top of a kitchen range place rapidly. As an alternative embodiment, the air outlet 6 may also be provided on a wall of the kitchen space. As another alternative, the air outlet 6 is not directly aligned with the user for blowing, and a circulation path is formed between the kitchen air inlet 123 and the air outlet 6, and the circulation path passes through the cooking bench area to cool the cooking bench area in a targeted manner, so that the oil smoke near the cooking bench can be better discharged, and the oil smoke and the smoke can be further removed on the basis of solving the problem that the temperature of the local area is increased at a high speed. The problem of lampblack overflow and dispersion caused by incomplete lampblack absorption of the range hood is solved. At this time, the kitchen air inlet 123 and the kitchen air outlet 6 may be both disposed on the ceiling to form a U-shaped circulation path through the cooking bench area. The kitchen air inlet 123 and outlet 6 can also be arranged on the ceiling and on the wall, respectively, forming a bent circulation path through the cooktop area.

Further, referring to fig. 2 and 4, the temperature sensor 20 is disposed on the intake vent 12, or in the duct assembly 22 near the intake vent 12, or along the airflow path from the intake vent 12 to the evaporator 3.

This embodiment is exemplified by: the invention has four temperature sensors 20, which are respectively arranged in the T kitchen and at the positions of three other air inlets 12: the kitchen air inlet 123 (abbreviated as T1), the indoor non-kitchen air inlet 123 (abbreviated as T2), and the outdoor air inlet 122 (abbreviated as T3).

The air inlet 12 is provided with an air door 19, and the air door 19 at least has a first position for closing the air inlet 12 and a second position for opening the air inlet 12. An electric valve 15 is arranged in the air duct assembly 22, the electric valve 15 is preferably a solenoid valve, the electric valve 15 is in communication connection with the temperature sensor 20, and is controlled in a linkage manner according to signals of the temperature sensor 20, and the air door 19 is controlled by the electric valve 15 to perform opening and closing actions.

Preferably, the first preset temperature threshold is 30 ℃ and the second preset temperature threshold is 27 ℃.

The host 100 operates at an initial allowed time with all of the intakes 12 open by default. After the main machine 100 runs for 30 minutes and maintains a stable state, the T kitchen is detected, and when the T kitchen is still higher than or equal to 30 ℃, namely, the temperature is higher than the first temperature preset threshold value and is 30 ℃, 3 air inlets 12 are continuously and fully opened, so that the refrigeration effect is rapidly improved.

When the temperature is lower than a first preset temperature threshold value and is not lower than a second preset temperature threshold value; for example, when the temperature of the T kitchen is less than 30 degrees and is kept for more than three minutes, the temperatures of T1, T2 and T3 are detected, the air inlet 12 with the highest temperature among the three temperatures is closed, and the other two air inlets 12 are still opened.

When the temperature is lower than a second preset threshold, one or more of the air inlets 12 with the measured higher temperature are closed. For example, when the temperature of the T kitchen is less than or equal to 27 ℃, the temperature is kept for more than three minutes, the temperature of the remaining two air inlets is detected, the air inlet with the highest temperature is closed, and only the air inlet with the lowest temperature is kept.

On the contrary, when the temperature of the T kitchen is more than 27 ℃ and lasts for three minutes, the two rest air inlets 12 are fully opened; and detecting a T kitchen after running for 30 minutes, and when the temperature of the T kitchen is more than or equal to 30 ℃, fully opening air inlets 1, 2 and 3. The automatic temperature-based control system can be automatically opened and closed according to the temperature, reduces the power consumption and enables products to be more intelligent.

In conclusion, when cooking is started in summer, the temperature in a kitchen is extremely high and can reach 35 ℃ or even more than 40 ℃, and in order to cool the kitchen as soon as possible, the air conditioner increases the air intake and improves the refrigerating capacity at the initial stage of operation by introducing three air intake modes; when the temperature of the kitchen is reduced to a certain temperature, for example, 30 ℃, the temperature of the kitchen is not too hot, and in order to save energy, the temperatures of the three air inlets 12 are detected, and the air inlet with the highest temperature is closed; when the kitchen temperature continues to decrease to a certain temperature, for example 27 ℃, the highest temperature intake air is closed again for energy saving. And finally only the inlet air with the lowest temperature is reserved. The user can enjoy cool air, and the refrigerating effect needs to be rapidly improved.

In the above, the first temperature preset threshold and the second temperature preset threshold can be set according to the environmental requirements.

The filter screen assembly 21 is arranged on the air inlet 12 or in the air duct assembly 22, the filter screen assembly 21 prevents dust in the air from being directly adsorbed on the evaporator 3, and the problem that the dust on the evaporator 3 is increased to block a gap on an aluminum foil of the evaporator 3, so that heat exchange is influenced, and the refrigerating effect is poor is avoided.

Second preferred embodiment:

a refrigeration control method of a kitchen air conditioner, referring to fig. 4,

the method comprises the following steps:

acquiring the kitchen temperature after the operation for a set time period, wherein the operation set time period is 30 min; at the initial allowable time, all the intake ports 12 are opened by default.

When the kitchen temperature meets the preset condition, the air duct assembly 22 is controlled to switch on or off one or more air inlets 12.

Specifically, a first preset temperature threshold value is obtained, the first preset temperature threshold value is 30 ℃, and when the kitchen temperature is greater than or equal to 30 ℃ and lasts for 3min, the air duct assembly 22 is controlled to switch on all the air inlets 12.

And acquiring the temperature of all the air inlets 12, and when at least two or more air inlets 12 are in an open state, the kitchen temperature is less than 30 ℃, and the duration is 3min, closing the air duct assembly 22 at the air inlet 12 with the highest temperature.

A second preset temperature threshold is obtained, where the second preset temperature threshold may be one or more temperature values with temperatures gradually lower than the first preset temperature threshold, and in this embodiment, for convenience of description, only one temperature value is taken as an example, for example, 27 ℃.

When the kitchen temperature is less than or equal to 27 ℃ and lasts for 3min, closing the air inlet 12 with the highest current temperature by the air duct assembly 22;

conversely, when the kitchen temperature is greater than the current 27 ℃ for 3min, the air duct assembly 22 is opened to the lower inlet 12.

When the second temperature preset threshold is two, the air inlet 12 with the lower temperature is switched on or off in a gradual lifting mode. It is sufficient to satisfy the above control logic.

The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims.
