The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a kitchen air conditioner 100 according to an embodiment of the present invention.
In the example of fig. 1, the kitchen air conditioner 100 according to the embodiment of the present invention includes an electronic expansion valve 110 and a compressor 120, and further includes an evaporator 130, an evaporation fan 140, a first temperature sensor 210, a second temperature sensor 220, a humidity sensor 230, and a controller 300. The controller 300 can adjust the control parameter of the electronic expansion valve 110, thereby adjusting the opening degree of the electronic expansion valve 110 and controlling the flow rate of the refrigerant entering the evaporator 130. The evaporator 130 absorbs heat from the low-pressure liquid refrigerant flowing thereinto and evaporates the refrigerant into a low-pressure gaseous refrigerant. The compressor 120 can extract a low-pressure gaseous refrigerant and compress the low-pressure gaseous refrigerant into a high-pressure gaseous refrigerant, and the controller 300 can control the output of the high-pressure gaseous refrigerant by controlling the operating frequency of the compressor 120, thereby adjusting the refrigerant flow rate.
The first temperature sensor 210 may be disposed at one side of the evaporation fan 140, so that the controller 300 can acquire the outlet air temperature through the first temperature sensor 210. The second temperature sensor 220 and the humidity sensor 230 may be located outside the kitchen air conditioner 100 or in an environment where the kitchen air conditioner 100 is located, and thus, the controller 300 can acquire the ambient temperature through the second temperature sensor 220 and the ambient humidity through the humidity sensor 230.
The electronic expansion valve 110 is connected to the evaporator 130, so that the electronic expansion valve 110 can transport the refrigerant to the evaporator 130. The outlet end of the evaporator 130 is connected to the compressor 120, and the compressor 120 receives the refrigerant from the evaporator 130, processes the refrigerant, cools the refrigerant into a liquid by the condenser 150, and then delivers the liquid to the electronic expansion valve 110. The evaporation fan 140 is disposed at one side of the evaporator 130, and can blow out the low-temperature air on the surface of the evaporator 130 to form cold air. The controller 300 can adjust the air outlet volume by adjusting the rotation speed of the evaporation fan 140. When the rotation speed of the evaporation fan 140 is higher, the outlet air volume of the kitchen air conditioner 100 is larger, and the outlet air temperature is higher.
It should be noted that, in the case where the water vapor content in the air is not changed and the air pressure is not changed, the temperature at which the air is cooled to reach saturation may be regarded as the condensation temperature. When the temperature of the air is lower than the condensation temperature, water vapor in the air can be separated out under certain conditions to form condensed water. Therefore, through adjusting the air outlet volume of the kitchen air conditioner 100, the opening degree of the electronic expansion valve 110 and the operating frequency of the compressor 120, the air outlet temperature of the kitchen air conditioner 100 can be increased, so that the air outlet temperature is higher than the condensation temperature, and the water vapor in the air is prevented from being precipitated, thereby achieving the effect of preventing condensation, heat insulating materials such as sponge are not required to be arranged outside the kitchen air conditioner 100, and the heat insulating materials such as sponge are prevented from breeding a large amount of bacteria under the kitchen environment with high temperature, high humidity and much oil contamination, and polluting the air in the kitchen environment.
The kitchen air conditioner 100 described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not constitute a limitation to the technical solution provided in the embodiment of the present invention, and it is known to those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems with the evolution of the kitchen air conditioner 100 and the occurrence of new application scenarios.
It will be appreciated by those skilled in the art that the configuration of the galley air conditioner 100 shown in fig. 1 is not intended to limit embodiments of the present invention and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
Based on the structure of the kitchen air conditioner 100, various embodiments of the anti-condensation control method of the present invention are proposed.
As shown in fig. 2, fig. 2 is a flowchart of an anti-condensation control method provided in an embodiment of the present invention, which can be applied to the kitchen air conditioner shown in fig. 1, and the anti-condensation control method includes, but is not limited to, the following steps:
step S100, acquiring the air outlet temperature of the kitchen air conditioner, the environmental temperature and the environmental humidity of the environment where the kitchen air conditioner is located;
step S200, obtaining condensation temperature according to the environment temperature and the environment humidity;
and step S300, performing combined control on the air outlet volume of the kitchen air conditioner, the opening of the electronic expansion valve and the operating frequency of the compressor according to the condensation temperature and the air outlet temperature, so that the condensation temperature and the air outlet temperature meet the condensation preventing condition.
It can be understood that the condensation temperature of the environment where the kitchen air conditioner is currently located is calculated according to the ambient temperature and the ambient humidity. Through air-out temperature and condensation temperature, carry out synchronous regulation to the air-out amount of wind of kitchen air conditioner, electronic expansion valve's aperture and the operating frequency of compressor to improve the air-out temperature, and then change ambient temperature, change the condensation temperature, make condensation temperature and air-out temperature accord with and prevent the condensation condition, reduce the condensation risk of kitchen air conditioner. Therefore, through the air outlet volume of the combined control kitchen air conditioner, the aperture of the electronic expansion valve and the operating frequency of the compressor, the air outlet temperature is improved, the condensation risk of the kitchen air conditioner can be reduced without adopting heat insulating materials such as sponge, dew generated by the kitchen air conditioner or sponge arranged on the kitchen air conditioner is avoided, bacteria are bred in the environment with high temperature and high humidity and more oil stains in a kitchen, the air in the kitchen environment is polluted, and the use experience of a user can be improved.
It should be noted that, in the related art, there is also a scheme of simply adjusting the air outlet volume of the kitchen air conditioner and the opening degree of the electronic expansion valve to reduce the risk of condensation, or simply adjusting the operating frequency of the compressor to reduce the risk of condensation, but in these related arts, other problems are introduced, for example, in the scheme of simply adjusting the air outlet volume of the kitchen air conditioner and the opening degree of the electronic expansion valve to reduce the risk of condensation, because the opening degree of the electronic expansion valve is increased, the flow rate of the refrigerant flowing into the evaporator is increased, the evaporation area of the evaporator is fixed, when the opening degree of the electronic expansion valve exceeds a certain threshold value, too much refrigerant enters the evaporator to cause incomplete evaporation of part of the refrigerant, so that the refrigerant forms a gas-liquid mixed state, and when the gas-liquid mixed refrigerant enters the compressor, the compressor has a liquid impact problem, thereby affecting the normal operation and service life of the compressor. For another example, in a scheme of simply adjusting the operating frequency of the compressor to reduce the risk of condensation, although reducing the operating frequency of the compressor can reduce the risk of condensation, reducing the operating frequency of the compressor can reduce the amount of cold output by the kitchen air conditioner, thereby affecting the use experience of the user.
In order to solve the problems in the related art, in this embodiment, the air outlet volume of the kitchen air conditioner, the opening degree of the electronic expansion valve, and the operating frequency of the compressor are jointly controlled according to the condensation temperature and the air outlet temperature, and under the condition that the opening degree of the electronic expansion valve is increased and the air outlet volume of the kitchen air conditioner is increased to reduce the loss of the refrigerating capacity of the kitchen air conditioner, the operating frequency of the compressor is reduced at the same time, and the flow rate of the refrigerant entering the electronic expansion valve is reduced, so that the flow rate of the refrigerant entering the evaporator is reduced, the liquid impact problem caused by incomplete evaporation of the refrigerant at the evaporator is avoided, and the service life of the kitchen air conditioner can be prolonged.
It should be noted that, under the condition that the water vapor content in the air is not changed and the air pressure is kept unchanged, the temperature when the air is cooled to reach saturation is the condensation temperature, that is, when the air temperature is lower than the condensation temperature and the temperature difference between the air temperature and the condensation temperature is greater than a certain threshold value, the water vapor in the air can be separated out to form condensed water droplets. When the condensation temperature is less than or equal to the air outlet temperature, the temperature of the air blown by the kitchen air conditioner is high, the surface temperature of the kitchen air conditioner is high, and water vapor is difficult to form condensed water drops, so that the condensation risk of the kitchen air conditioner is low in the condition. Therefore, it is considered that the condensation temperature being equal to or lower than the outlet air temperature is one of the condensation preventing conditions of the kitchen air conditioner.
It should be noted that, under the condition that the temperature of the air blown by the kitchen air conditioner is lower than the condensation temperature, or the surface temperature of the kitchen air conditioner is lower than the condensation temperature, the temperature difference between the condensation temperature and the air outlet temperature does not exceed the preset temperature threshold, and even if the water vapor in the air meets cold air or a low-temperature object, the water vapor is difficult to condense to form water droplets, and the use experience of the user is not affected. Therefore, the anti-condensation condition further includes that the condensation temperature is greater than the air outlet temperature, and the temperature difference between the condensation temperature and the air outlet temperature is smaller than or equal to the preset temperature threshold. Therefore, through the joint control kitchen air conditioner for condensation temperature and air-out temperature accord with and prevent the condensation condition, and condensation temperature is less than or equal to the air-out temperature promptly, and perhaps condensation temperature is greater than the air-out temperature, and condensation temperature and air-out temperature's the difference in temperature is less than or equal to and predetermines the temperature threshold value, thereby vapor in the kitchen air conditioner environment is located is difficult to separate out and forms the condensation drop, reduces kitchen air conditioner's condensation risk, improves user's use and experiences.
It should be noted that factors that affect the formation of condensation include the moisture content of the air, the ambient air pressure, and the ambient temperature. Due to the fact that the ambient temperature in the kitchen environment at different times is different, or in different scenes, such as a scene in which cooking is performed or a scene after cooking is finished, the temperature of the kitchen environment and the moisture content in the air are different. Therefore, preset temperature threshold value can be adjusted according to atmospheric pressure, humidity and the temperature of current kitchen environment and set up for preset temperature threshold value can accord with the condition of current kitchen air conditioner environment, avoids preset temperature threshold value and current environment to mismatch, leads to the misjudgment, and the kitchen air conditioner is adjusted to the mistake, makes to form the condensation drop in the kitchen environment, influences user's use and experiences.
As shown in fig. 3, fig. 3 is a detailed flowchart of step S300 in fig. 2, and in the example of fig. 3, step S300 further includes, but is not limited to, step S310:
and S310, when the condensation temperature is higher than the air outlet temperature and the temperature difference between the condensation temperature and the air outlet temperature is higher than a preset temperature threshold value, increasing the air outlet volume of the kitchen air conditioner to a first air volume, increasing the opening degree of the electronic expansion valve to a first opening degree, and reducing the operating frequency of the compressor to a first operating frequency.
It can be understood that, by comparing the condensation temperature with the air outlet temperature, if the condensation temperature is higher than the air outlet temperature in the current state and the temperature difference between the condensation temperature and the air outlet temperature exceeds a preset temperature threshold, water vapor in the air can meet the condensation to form liquid water drops. Consequently, increase kitchen air conditioner's air-out amount of wind to first amount of wind, increase electronic expansion valve's aperture to first aperture, reduce the operating frequency of compressor to first operating frequency simultaneously, can improve kitchen air conditioner's air-out temperature, thereby adjust the ambient temperature of kitchen air conditioner place environment, and then adjust the condensation temperature, make air-out temperature and condensation temperature accord with and prevent the condensation condition, reduce kitchen air conditioner's condensation risk, consequently, need not to adopt thermal insulation material such as sponge and can reduce the condensation risk, avoid thermal insulation material such as sponge and condensation water droplet under kitchen high temperature and high humidity and the environment that the greasy dirt is many, breed a large amount of bacteriums, pollute the air in the kitchen environment, influence user's use experience.
As shown in fig. 4, fig. 4 is another specific flowchart of step S300 in fig. 2, and in the example of fig. 4, step S300 further includes, but is not limited to, step S320 and step S330:
step S320, keeping the kitchen air conditioner continuously operating for a preset time length at a first air volume, a first opening degree of the electronic expansion valve and a first operating frequency of the compressor;
and S330, when the operation time of the kitchen air conditioner reaches the preset time, acquiring the air outlet temperature of the kitchen air conditioner, the environment temperature and the environment humidity of the environment where the kitchen air conditioner is located again, acquiring new condensation temperature according to the acquired environment temperature and the acquired environment humidity, and performing joint control on the air outlet volume of the kitchen air conditioner, the opening degree of the electronic expansion valve and the operation frequency of the compressor again according to the new condensation temperature and the acquired air outlet temperature.
It can be understood that, when the condensation temperature is greater than the air-out temperature and the temperature difference between the condensation temperature and the air-out temperature exceeds the preset temperature threshold, it is considered that water vapor in the air is easily condensed into water drops in the current environment, and the user experience is reduced, therefore, in order to effectively increase the air-out temperature and reduce the condensation risk of the kitchen air conditioner, after the air-out volume of the kitchen air conditioner, the opening degree of the electronic expansion valve and the operating frequency of the compressor are adjusted, the kitchen air conditioner needs to be kept operating at the first air volume, the electronic expansion valve at the first opening degree and the compressor at the first operating frequency for a preset duration, sufficient time is provided for the kitchen air conditioner to increase the air-out temperature, the air-out temperature is ensured to be increased, the ambient temperature of the environment where the kitchen air conditioner is located is adjusted, so that the air-out temperature and the condensation temperature meet the condensation preventing condition, the condensation risk of the kitchen air conditioner is reduced.
It can be understood that after the operation time of the kitchen air conditioner reaches the preset time, the air outlet temperature and the condensation temperature are changed, the condition that water vapor is condensed into water drops is changed, and the condensation risk of the kitchen air conditioner needs to be judged again so as to improve the accuracy and the effectiveness of the adjustment of the kitchen air conditioner. Therefore, the ambient temperature and the ambient humidity are acquired again, and calculation processing is performed according to the acquired ambient temperature and the acquired ambient humidity to obtain a new condensation temperature. And acquiring the air outlet temperature again, namely the adjusted air outlet temperature, judging the condensation risk of the kitchen air conditioner by comparing the new condensation temperature with the re-acquired air outlet temperature, and controlling the air outlet volume, the opening and the operating frequency again in a combined manner.
If the new condensation temperature and the newly acquired outlet air temperature do not meet the condensation prevention condition, it can be considered that the kitchen air conditioner still has a condensation risk, and the outlet air volume of the kitchen air conditioner can be continuously increased, the opening degree of the electronic expansion valve can be increased, and the operating frequency of the compressor can be reduced, for example, the outlet air volume of the kitchen air conditioner can be increased from a first air volume to a second air volume, the opening degree of the electronic expansion valve can be increased from the first opening degree to the second opening degree, and the operating frequency of the compressor can be reduced from the first operating frequency to the second operating frequency; the kitchen air conditioner can be continuously kept to operate at the first opening degree by the first air quantity and the electronic expansion valve, and the compressor operates at the first operation frequency, so that the air outlet temperature of the kitchen air conditioner is improved, the current air outlet temperature and the new condensation temperature can accord with the anti-condensation condition, and the condensation risk of the kitchen air conditioner is reduced.
If the new condensation temperature and the newly acquired outlet air temperature meet the condensation prevention condition, the kitchen air conditioner is low in condensation risk, the kitchen air conditioner can be kept to operate at a first air volume and at a first opening degree by the electronic expansion valve, the compressor operates at a first operation frequency, or the outlet air volume of the kitchen air conditioner is reduced from the first air volume to a normal refrigeration air volume, the opening degree of the electronic expansion valve is reduced from the first opening degree to a normal refrigeration opening degree, and the operation frequency of the compressor is increased from the first operation frequency to the normal refrigeration operation frequency.
Therefore, under the condition that the condensation risk is low, the air outlet temperature can be adjusted according to the setting of the user, and the use requirement of the user is met. When predetermineeing through the setting, to the air-out temperature of kitchen air conditioner, the ambient temperature and the ambient humidity of environment of locating, judge the condensation risk once more to according to the temperature data and the humidity data that acquire, joint control kitchen air conditioner once more improves the air-out temperature, avoids kitchen air conditioner to produce the condensation. Therefore, the condensation risk of the kitchen air conditioner can be reduced without adopting heat insulating materials such as sponge and the like, dew generated by the kitchen air conditioner or sponge arranged on the kitchen air conditioner is avoided, bacteria are bred in the environment with high temperature and high humidity and much oil stains in a kitchen, and the use experience of a user can be improved.
It should be noted that the preset time duration may be a time parameter preset by a user, and may be adjusted and set according to the temperature, humidity or condensation temperature in the current environment. The preset time period may be set to 5 minutes or 10 minutes. Because the air-out temperature and the ambient temperature can change gradually in a certain time, the preset duration of the kitchen air conditioner is set to ensure the accuracy and authenticity of the air-out temperature and the ambient temperature, and then the kitchen air conditioner is accurately controlled. Thereby can avoid appearing the maloperation, frequently acquire air-out temperature and condensation temperature, frequently carry out joint control to air-out amount of wind, aperture and operating frequency, not only can't effectively reduce the condensation risk, evaporation fan, electronic expansion valve and compressor among the kitchen air conditioner damage because of frequent regulation moreover, reduce kitchen air conditioner's life. And if the joint control time is long, although the air-out temperature can be effectively improved, because the air-out temperature is improved for a long time, the temperature of the kitchen environment can not be adjusted to the temperature required by the user, and the use experience of the user is influenced. Therefore, preset duration through setting up for kitchen air conditioner can last to be operated to preset duration with first amount of wind, first aperture and first operating frequency, improves the air-out temperature, reduces the condensation risk, and can satisfy user's user demand, improves user's use and experiences.
As shown in fig. 5, fig. 5 is another specific flowchart of step S300 in fig. 2, and in the example of fig. 5, step S300 further includes, but is not limited to, step S340:
and step S340, when the condensation temperature is less than or equal to the air outlet temperature, keeping the air outlet volume of the kitchen air conditioner at the current air outlet volume, keeping the opening degree of the electronic expansion valve at the current opening degree, and keeping the running frequency of the compressor at the current running frequency.
It can be understood that, in the case that the condensation temperature is less than or equal to the outlet air temperature, this means that in the environment where the current outlet air temperature is greater than the condensation temperature, the water vapor in the air is difficult to separate out and condense into water droplets. Therefore, the air outlet volume, the opening degree and the operating frequency under the current state are kept unchanged, namely the air outlet temperature is higher than the condensation temperature, water drops are avoided, and the effect of preventing condensation is achieved. According to condensation temperature and air-out temperature, the air-out amount of wind of joint control kitchen air conditioner, electronic expansion valve's aperture and compressor operating frequency, need not to adopt thermal insulation materials such as sponge just can reduce kitchen air conditioner's condensation risk, avoid the dew that kitchen air conditioner produced or set up the sponge at kitchen air conditioner, breed the bacterium in the environment that kitchen high temperature and high humidity and greasy dirt are many, and pollute the air in the kitchen environment, thereby can improve user's use and experience.
As shown in fig. 6, fig. 6 is another specific flowchart of step S300 in fig. 2, and in the example of fig. 6, step S300 further includes, but is not limited to, step S350:
and step S350, when the condensation temperature is higher than the air outlet temperature and the temperature difference between the condensation temperature and the air outlet temperature is smaller than or equal to a preset temperature threshold value, keeping the air outlet volume of the kitchen air conditioner at the current air outlet volume, keeping the opening degree of the electronic expansion valve at the current opening degree, and keeping the operating frequency of the compressor at the current operating frequency.
It can be understood that when the condensation temperature is greater than the air outlet temperature and the temperature difference between the condensation temperature and the air outlet temperature is less than or equal to the preset temperature threshold, it can be considered that the kitchen air conditioner does not condense water droplets under the conditions of the current condensation temperature and the current air outlet temperature. Therefore, the condensation temperature and the air outlet temperature can meet the condensation preventing condition by keeping the current air outlet volume of the kitchen air conditioner, the current opening degree of the electronic expansion valve and the current operating frequency of the compressor, the condensation risk of the kitchen air conditioner can be reduced without adopting heat insulating materials such as sponge and the like, and the breeding of a large amount of bacteria in the high-temperature, high-humidity and greasy kitchen environment can be avoided by treating and comparing the air outlet temperature, the environment temperature and the environment humidity of the kitchen air conditioner, the air outlet volume of the kitchen air conditioner, the opening degree of the electronic expansion valve and the operating frequency of the compressor can be controlled in a combined manner, the condensation risk of the kitchen air conditioner can be reduced without adopting heat insulating materials such as sponge and the like, dew generated by the kitchen air conditioner or sponge arranged in the kitchen air conditioner can be avoided, and the bacteria can be bred in the high-temperature, high-humidity and greasy environment of the kitchen, and air in the kitchen environment is polluted, so that the use experience of the user can be improved.

Further, the memory 710 may include high speed random access memory 710, and may also include non-transitory memory 710, such as at least one magnetic disk storage device, flash memory device, or other non-transitory solid state storage device. It is noted that the memory 710 may optionally include memory 710 located remotely from the processor 720, and that such remote memory 710 may be coupled to the terminal via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
Non-transitory software programs and instructions required to implement the anti-condensation control method in the above-described embodiments are stored in a memory, and when executed by one or more processors, perform the anti-condensation control method in the above-described embodiments, for example, performing the above-described method steps S100 to S300 in fig. 2, method step S310 in fig. 3, method steps S320 to S330 in fig. 4, method step S340 in fig. 5, and method step S350 in fig. 6.
As shown in fig. 8, the present invention further provides a kitchen air conditioner 100, which includes an electronic expansion valve 110, a compressor 120 and the anti-condensation control device 700 in the above embodiment, wherein the anti-condensation control device 700 is electrically connected to the electronic expansion valve 110 and the compressor 120 respectively.
It can be understood that, kitchen air conditioner 100 can carry out joint control through preventing condensation controlling means 700 to kitchen air conditioner 100's the air-out amount of wind, electronic expansion valve 110's aperture and compressor 120's operating frequency, thereby, improve the air-out temperature, need not to adopt thermal insulation material such as sponge just can reduce kitchen air conditioner 100's condensation risk, dew or the sponge of setting at kitchen air conditioner 100 that avoid kitchen air conditioner 100 to produce, breed the bacterium in the environment that kitchen high temperature and high humidity and greasy dirt are many, and pollute the air in the kitchen environment, thereby can improve user's use experience.
It should be noted that the outlet end of the electronic expansion valve 110 is connected to the evaporator 130, the inlet end of the electronic expansion valve 110 is connected to the condenser 150, the outlet end of the compressor 120 is connected to the condenser 150, and the inlet end of the compressor 120 is connected to the evaporator 130, thereby forming a condensation loop.
Wherein, an evaporation fan 140 is provided at one side of the evaporator 130, and the evaporation fan 140 can blow out low-temperature air near the evaporator 130. In addition, the condensation prevention control device 700 can also be electrically connected with the evaporation fan 140, so that the rotating speed of the evaporation fan 140 can be adjusted, and the air outlet volume can be changed.
If the opening degree of the electronic expansion valve 110 is individually adjusted, the flow rate of the refrigerant flowing into the evaporator 130 in a unit time is increased, the evaporation area of the evaporator 130 is fixed, and the excessive refrigerant entering the evaporator 130 may cause the evaporator 130 not to evaporate all the refrigerant, thereby increasing the outlet air temperature and reducing the occurrence of condensation. After the gas-liquid mixed refrigerant enters the compressor 120, a liquid impact problem occurs, which affects the normal operation of the compressor 120 and damages the compressor 120.
If the operation frequency of the compressor 120 is independently adjusted, although the risk of condensation can be reduced by reducing the operation frequency, the reduction of the operation frequency of the compressor 120 reduces the amount of cooling output by the kitchen air conditioner 100, thereby affecting the user experience.
Therefore, the loss of the refrigerating capacity of the kitchen air conditioner 100 is reduced by increasing the rotation speed of the evaporation fan 140 and the opening degree of the electronic expansion valve 110, the operation frequency of the compressor 120 is reduced, and the flow rate of the refrigerant entering the electronic expansion valve 110 is reduced, so that the flow rate of the refrigerant entering the evaporator 130 is reduced, the liquid impact problem caused by the fact that the liquid refrigerant enters the compressor 120 due to incomplete evaporation of the refrigerant at the evaporator 130 is avoided, and the service life of the kitchen air conditioner 100 can be prolonged. Wherein, air exhauster 170 is provided with first wind channel 180 and second wind channel 190, and air exhauster 170 is connected with condenser 150 through first wind channel 180, and air exhauster 170 is connected with lampblack absorber 160 through second wind channel 190 to make kitchen air conditioner 100 can have the effect of absorbing the oil smoke, and save space, the user of being convenient for uses, improves user's use and experiences.
It should be noted that the kitchen air conditioner 100 may further be provided with a first temperature sensor 210, a second temperature sensor 220, and a humidity sensor 230. The first temperature sensor 210 may be disposed near the evaporation fan 140, so that the first temperature sensor 210 may acquire the outlet air temperature. The second temperature sensor 220 and the humidity sensor 230 may be disposed at an outer side of the kitchen air conditioner 100 such that the second temperature sensor 220 can acquire an ambient temperature of an environment where the kitchen air conditioner 100 is located, and the humidity sensor 230 can acquire an ambient humidity. First temperature sensor 210, second temperature sensor 220 and humidity transducer 230 can be connected with prevent condensation controlling means 700, consequently prevent that condensation controlling means 700 can be through acquireing first temperature sensor 210, second temperature sensor 220 and humidity transducer 230's detection data, ambient temperature and ambient humidity through the present moment calculate and obtain the condensation temperature, and utilize condensation temperature and air-out temperature to judge the condensation risk, and then carry out the accurate condensation control of preventing to kitchen air conditioner 100.
It can be understood that the air outlet channel 200 is connected to the evaporator 130, and the evaporation fan 140 located at one side of the evaporator 130 can blow the low-temperature air near the evaporator 130 into the air outlet channel 200, so that the kitchen air conditioner 100 can output air through the air outlet 240 of the air outlet channel 200 to adjust the ambient temperature.
Since the kitchen air conditioner 100 further includes the range hood 160, it has an effect of sucking oil smoke, and in order to improve an effect of sucking oil smoke, the range hood 160 is disposed below the air outlet 240 or at a position horizontal to the air outlet 240. If the air outlet 240 of the kitchen air conditioner 100 sets up the angle and is greater than thirty degrees below the horizontal, then can blow to the lampblack absorber 160 from the cold wind or hot-blast cold wind that the kitchen air conditioner 100 blown through the air outlet 240, and the lampblack absorber 160 can directly absorb cold wind or hot-blast, therefore the kitchen air conditioner 100 can not adjust ambient temperature, influence user's use experience, lead to the air-out passageway 200 inside and outside difference in temperature too big even, and produce a large amount of pearls that condense, seriously influence user's result of use. Therefore, the setting angle of the air outlet 240 of the kitchen air conditioner 100 is smaller than or equal to thirty degrees from horizontal to bottom, so that the air supply effect can be improved, the kitchen air conditioner 100 can adjust the ambient temperature, the use requirement of a user is met, and the use experience of the user is improved.
It should be noted that the range hood 160 may further be provided with a smoke suction port, and an included angle between the orientation of the smoke suction port and the orientation of the air outlet 240 is not more than thirty degrees, so that cold air blown from the air outlet 240 is sucked into the range hood 160 and then discharged out of the kitchen room due to convection of air between the smoke suction port and the air outlet 240, which results in that the kitchen air conditioner 100 cannot adjust the environmental temperature of the kitchen, affects the use of a user, and wastes resources.
It should be noted that, in the case that the kitchen air conditioner 100 is provided with the first temperature sensor 210, the second temperature sensor 220 and the humidity sensor 230, the first temperature sensor 210 may be disposed in the air outlet channel 200, so that the first temperature sensor 210 obtains the air outlet temperature in the air outlet channel 200. Because the air outlet channel 200 can be used for outputting cold air, when the kitchen air conditioner 100 is in a refrigeration state, the surface temperature of the air outlet channel 200 is low, and water vapor in the air is easy to form condensation beads on the outer surface or the inner surface of the air outlet channel 200. The condensation beads are easy to breed bacteria or have oil stains under the conditions of high temperature, high humidity and much oil stains.
If the condensation beads are formed on the outer surface of the air outlet channel 200, the condensation beads easily slide down along the outer surface of the air outlet channel 200 due to the action of gravity, and carry dust, oil stains or bacteria on the outer surface of the air outlet channel 200 to drip down, so that the kitchen environment is polluted. If the condensation beads are formed on the inner surface of the air outlet channel 200, the condensation beads carrying bacteria or oil dirt will be sucked by the human body through the wind force blown by the kitchen air conditioner 100, which affects the health of the user. Therefore, first temperature sensor 210 sets up in air-out passageway 200, can judge whether the air-out passageway 200 of kitchen air conditioner 100 can produce the condensation pearl, and monitoring air-out passageway 200's condensation risk is favorable to reducing the condition that bacterial growing, can improve the air quality of kitchen environment, improves user's use and experiences.
The second temperature sensor 220 and the humidity sensor 230 may be disposed on an outer surface of the wind outlet channel 200, so that the second temperature sensor 220 can acquire an ambient temperature and the humidity sensor 230 can acquire an ambient humidity. Therefore, through setting up first temperature sensor 210 in air-out passageway 200, set up second temperature sensor 220 and humidity transducer 230 outside air-out passageway 200, first temperature sensor 210, second temperature sensor 220 and humidity transducer 230 can mutually support, can improve the air-out temperature, ambient temperature and ambient humidity measuring accuracy, thereby can accurately calculate and obtain the condensation temperature, and then can accurately compare condensation temperature and air-out temperature and come to monitor kitchen air conditioner 100's air-out passageway 200, and control kitchen air conditioner 100, can improve accuracy and reliability that kitchen air conditioner 100 adjusted, be favorable to improving the sanitary conditions of kitchen environment, improve user's use and experience.
