Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
An oxygen-increasing fresh air conditioner 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 14.
As shown in the attached drawings, the oxygen-increasing fresh air conditioner comprises: a casing (not shown in the figure), a fresh air casing 10, a fresh air pipe 20, a fresh air blower (not shown in the figure) and an oxygen increasing device (not shown in the figure).
Wherein, the new trend shell 10 sets up in the casing, and new trend shell 10 sets up new trend air intake 11 and oxygenation air intake 12. Therefore, fresh air flow enters the fresh air shell 10 through the fresh air inlet 11, and oxygen-enriched air flow enters the fresh air shell 10 through the oxygen-enriched air inlet 12.
And the fresh air pipe 20 is arranged at one side of the fresh air shell 10, one end of the fresh air pipe 20 is communicated with the outside, and the other end of the fresh air pipe 20 is communicated with the fresh air inlet 11, so that fresh air is introduced from the fresh air pipe 20 and is conveyed into the fresh air shell 10 through the fresh air inlet 11. So, the outdoor environment of one end intercommunication outdoor environment of new tuber pipe 20, the new trend air intake 11 of new tuber pipe 20's other end intercommunication new trend shell 10, like this, outdoor new trend is introduced from the one end of new tuber pipe 20 to carry to in the new trend shell 10 via new trend air intake 11.
And the fresh air fan is arranged in the fresh air shell 10, outdoor airflow is introduced into the fresh air shell 10 from the fresh air inlet 11 through the driving of the fresh air fan, and/or oxygen-enriched airflow entering the fresh air shell 10 from the oxygen-enriched air inlet 12 is conveyed outwards under the driving of the fresh air fan. So, be equipped with the new trend fan in new trend shell 10, after opening new trend air intake 11, under the drive operation of new trend fan, can introduce to new trend shell 10 with outdoor new trend through fresh air pipe 20 and new trend air intake 11 in to can carry the new trend air current to indoor under the drive operation of new trend fan. And, after opening oxygenation air intake 12, the oxygen boosting air current passes through oxygenation air intake 12 and gets into in the new trend shell 10, like this, under the drive operation of new trend fan, carries out the secondary to the pure oxygen that oxygenation device produced and enables it and get into indoorly comparatively smoothly to promote the oxygen content of interior space, improve user experience.
Compare in the longer and direct introduction oxygen exit of current oxygen therapy pipe for the pump gas resistance among the oxygenation device is great and lead to introducing the pure oxygen volume of air conditioner air outlet less and ageing relatively poor, the utility model provides a new trend fan among the oxygenation new trend air conditioner can carry out the secondary for the pure oxygen air current and energize, thereby can effectively improve the oxygen effect.
Moreover, the oxygen increasing device includes: the oxygenation cavity 30, oxygenation cavity 30 set up inside fresh air duct 20 to set up in fresh air duct 20 and close to the one end of fresh air shell 10 and communicate with oxygenation air intake 12, in order to make oxygenation cavity 30 introduce behind the oxygen-enriched air current and carry to fresh air shell 10 in via oxygenation air intake 12. So, oxygenation chamber 30 among the oxygenation device installs in the inside of new trend pipe 20 to be located new trend pipe 20 and be close to the one end of new trend shell 10, so that oxygenation chamber 30 and the oxygenation air intake 12 intercommunication of new trend shell 10, the pure oxygen that oxygenation device produced like this gets into oxygenation chamber 30, then carries to new trend shell 10 in through oxygenation air intake 12, so that the oxygen-enriched air current can release to indoor smoothly under the drive operation of new trend fan, improves indoor oxygen content.
That is to say, the introduced outdoor fresh air channel and the introduced oxygen-enriched air channel are independent from each other, so that the fresh air inlet 11 or the oxygen-enriched air inlet 12 can be selectively opened, or the fresh air inlet 11 and the oxygen-enriched air inlet 12 can be opened simultaneously.
Specifically, when the oxygen-increasing fresh air conditioner only opens the fresh air inlet 11, outdoor fresh air is introduced into the fresh air shell 10 through the fresh air pipe 20 and the fresh air inlet 11 under the driving operation of the fresh air fan, and then is released indoors under the driving operation of the fresh air fan, that is, the oxygen-increasing fresh air conditioner only opens the fresh air working mode;
when the oxygen-enriched fresh air conditioner only opens the oxygen-enriched fresh air inlet 11, oxygen-enriched air flow generated by the oxygen-enriching device is introduced into the oxygen-enriching cavity 30, is introduced into the fresh air shell 10 through the oxygen-enriching air inlet 12, and is then released indoors under the driving operation of the fresh air fan so as to realize the oxygen-enriching effect, namely, the oxygen-enriching fresh air conditioner only opens the oxygen-enriching working mode;
when the fresh air inlet 11 and the oxygen increasing air inlet 12 are opened simultaneously by the oxygen increasing fresh air conditioner, a channel entering the fresh air shell 10 is in a completely unblocked state, outdoor fresh air and oxygen-enriched air from the oxygen increasing device enter the fresh air shell 10 together, and then the fresh air is driven by the fresh air fan to enter the room, so that the quality of the indoor air is adjusted, namely, the oxygen increasing fresh air conditioner simultaneously starts an oxygen increasing working mode and a fresh air working mode.
In addition, oxygenation new trend air conditioner still includes: the dehumidifying component 40, a humidity sensor (not shown in the figures) and a controller (not shown in the figures), the dehumidifying component 40 is disposed inside the oxygen increasing cavity 30 for adsorbing moisture, and selectively heating the adsorbed moisture to generate water vapor which is then conveyed to the fresh air shell 10 from the oxygen increasing air inlet 12 along with the oxygen-rich air flow. And the humidity sensor is arranged inside the oxygen increasing cavity 30 and used for detecting the humidity value inside the oxygen increasing cavity 30. So, dehumidification subassembly 40 establishes inside oxygenation chamber 30, can adsorb the inside moisture in oxygenation chamber 30 to solve the inside liquid water that condenses of oxygenation device, prevent that the oxygen-enriched air current from carrying excessive liquid water and getting into indoorly. In addition, the dehumidifying component 40 can heat and dry the adsorbed moisture according to specific conditions, so that the generated water vapor is conveyed into the fresh air shell 10 along with the oxygen-enriched air flow through the oxygen-enriched air inlet 12, and kinetic energy can be given to the oxygen-enriched air flow under the driving operation of the fresh air fan, so that the oxygen-enriched air flow can be smoothly released indoors.
Wherein the controller is configured to control the dehumidifying assembly 40 to heat the adsorbed moisture when it is determined that the humidity value detected by the humidity sensor is greater than the first preset humidity threshold value. So, dehumidification subassembly 40 can adsorb the moisture in the oxygenation chamber 30, and when humidity transducer detected the humidity value in the oxygenation chamber 30 and was greater than first predetermined humidity threshold value, it had adsorbed the saturation to explain dehumidification subassembly 40, and at this moment, need dehumidification subassembly 40 to remove the adsorbed moisture of heating, and the vapor that produces like this releases to indoor along with the oxygen-enriched air current, and then for the indoor moist oxygen-enriched clean air of carrying.
It should be noted that, the above-mentioned dehumidification assembly 40 and the humidity sensor both work when the oxygen-enriched air inlet 12 is in the open state, so that the oxygen-enriched air flow carries the generated water vapor to be released indoors, otherwise, when only the fresh air inlet 11 is in the open state, i.e. the fresh air pipe 20 is communicated with the fresh air casing 10, the opening of the dehumidification assembly 40 and the humidity sensor has no working significance.
From this, through set up dehumidification subassembly 40 and humidity transducer in oxygenation chamber 30, like this, dehumidification subassembly 40 can adsorb the comdenstion water that condenses in the oxygenation device, and when humidity transducer detected the humidity value in oxygenation chamber 30 and is greater than first preset threshold value, then indicate that dehumidification subassembly 40 has adsorbed saturation, at this moment, controller control dehumidification subassembly 40 opens the dry heating function, carry out dry heating to the moisture that adsorbs, make the steam of production discharge indoor along with the oxygen-enriched air current, both can handle the comdenstion water in the oxygenation device like this, can also blow out moist oxygen-enriched air current. In addition, the generated water vapor has a certain temperature due to the heating effect, so that warmer oxygen-enriched air flow can be provided indoors, and the problem of large indoor temperature fluctuation is effectively solved particularly under the cold condition in winter.
Further, the dehumidifying assembly 40 includes: the dehumidifying part 41 and the heating part are arranged in the oxygen increasing chamber 30, the dehumidifying part 41 is used for absorbing moisture, and the heating part is used for heating the moisture in the dehumidifying part 41. So, dehumidification 41 and heating member all set up in oxygenation chamber 30, and dehumidification 41 is used for adsorbing the moisture in oxygenation chamber 30, and the heating member is used for heating the moisture that dehumidification 41 was adsorbed, like this, can realize the dry regeneration function of dehumidification 41 to can be lastingly and adsorb the moisture in oxygenation chamber 30 repeatedly.
Wherein the controller is specifically configured to control the heating element to heat the dehumidifying element 41 when it is determined that the humidity value detected by the humidity sensor is greater than a first preset humidity threshold value. So, under the state that oxygenation air intake 12 was opened, humidity transducer can detect the humidity value in the oxygenation chamber 30, if the humidity value is greater than first preset threshold value, it is saturated to explain to dehumidify 41 absorption, at this moment, controller control heating member work, in order to dehumidify 41 and carry out drying and heating, make dehumidify 41 can resume again to the state that can adsorb moisture, realized the used repeatedly characteristic of dehumidification subassembly 40, and effectively solved the problem of the liquid water that condenses in the oxygenation chamber 30, simultaneously still can be for indoor moist oxygen-enriched air current that improves.
And, the controller is specifically configured to control the heating member to stop working when the humidity value detected by the humidity sensor reaches the second preset humidity threshold value in the process that the heating member heats the dehumidifying member 41. Wherein the second preset humidity threshold is smaller than the first preset humidity threshold. That is, in the process of drying and regenerating the dehumidifying part 41 by the heating part, when the humidity value detected by the humidity sensor reaches the second preset threshold value, it indicates that the dehumidifying part 41 has recovered to the regeneration state capable of adsorbing moisture, and at this time, the controller controls the heating part to stop the heating operation. It should be noted that the second preset threshold is smaller than the first preset threshold, that is, the first preset threshold may represent an upper limit state of adsorption saturation of the dehumidifying part 41, and the second preset threshold may represent an initial state in which the dehumidifying part 41 can start adsorption.
The utility model discloses an among the embodiments, because new tuber pipe 20 is cylindrical structure, also design the oxygenation chamber 30 inside new tuber pipe 20 for cylindric structure to length direction along new tuber pipe 20 extends the setting, and, dehumidification piece 41 in the oxygenation chamber 30 can spiral structure, and extend the setting along the length direction in oxygenation chamber 30, can increase like this and dehumidify the adsorption area of piece 41, thereby can improve the adsorption efficiency who dehumidifies piece 41. In addition, spiral structure can set up the installation cavity in the middle part that length direction extends to make the heating member run through the length direction at dehumidification piece 41, thereby can carry out rapid draing heating, effectively improve heating rate to dehumidification piece 41. Of course, the heating element may be disposed outside the dehumidifying part 41, i.e. fixedly installed in the oxygen increasing chamber 30, and the heating function of the dehumidifying part 41 may also be achieved, however, it is preferable to dispose the heating element inside the dehumidifying part 41, so that the drying and heating efficiency can be greatly improved.
In addition, oxygenation device still includes: the oxygen supplying device comprises an oxygen supplying pump and an oxygen generating chamber, wherein the air inlet end of the oxygen supplying pump is communicated with the oxygen end of the oxygen generating chamber, and the air outlet end of the oxygen supplying pump is communicated with an oxygen supplying cavity 30 so as to convey the oxygen in the oxygen generating chamber to the oxygen supplying cavity 30.
Specifically, an oxygen film is arranged in the oxygen generation chamber, and the oxygen film can divide the oxygen generation chamber into two parts; the oxygen generating chamber can divide air into oxygen-enriched air (oxygen) with higher oxygen content and nitrogen-enriched air (nitrogen) with higher nitrogen content under the action of pressure by using an oxygen membrane. The oxygen membrane is driven by pressure difference to make oxygen in air pass through the membrane preferentially to obtain oxygen-enriched air by utilizing different permeation rates of each component in air when the components permeate through the membrane.
The air inlet end of the oxygen increasing pump is communicated with the oxygen end of the oxygen generating chamber, the air outlet end of the oxygen increasing pump is communicated with the oxygen increasing cavity 30, so that oxygen in the oxygen generating chamber is input into the oxygen increasing cavity 30 and enters the fresh air shell 10 through the oxygen increasing air inlet 12, and oxygen is secondarily energized under the driving of the fresh air fan, so that the oxygen is smoothly discharged into the chamber.
Specifically, the oxygenation pump has the inlet end and gives vent to anger the end, the inlet end of oxygenation pump and the oxygen end intercommunication of oxygen generation room, the inlet end of oxygenation pump and the higher oxygen boosting air end intercommunication of oxygen content promptly, the end of giving vent to anger of oxygenation pump and oxygenation chamber 30 intercommunication, the end of giving vent to anger of oxygenation pump and indoor environment intercommunication promptly, start the oxygenation pump, under the effect of pressure, can make the oxygen that produces in the oxygen enrichment facility finally introduce indoorly, improve the content of indoor oxygen, improve user's comfort level.
And the oxygen increasing device is also provided with an air outlet, one end of the air outlet is communicated with the nitrogen end of the oxygen generating chamber, and the other end of the air outlet is communicated with the outdoor environment so as to discharge the nitrogen out of the room. And an oxygen delivery pipeline 63 is arranged between the air outlet end of the oxygen increasing pump and the oxygen increasing cavity 30, so that oxygen generated by the oxygen generating chamber can be introduced into the oxygen increasing cavity 30 under the driving of the oxygen increasing pump.
Further, on the basis of the above-described embodiment, the controller is specifically configured to control the heating member to heat the dehumidifying member 41 and control the pumping rate of the oxygen increasing pump to decrease when it is determined that the humidity value detected by the humidity sensor is greater than the first preset humidity threshold value. That is to say, when humidity transducer detects that the humidity value in oxygenation chamber 30 is greater than first preset threshold value, the controller not only controls the heating member and heats dehumidification 41, but also controls the pump gas rate of oxygenation pump and reduces, thus, can slow down the volume of oxygen-enriched air flow direction oxygenation chamber 30 in, can make the vapor of production slowly flow to in the new trend shell 10 along with the oxygen-enriched air flow like this, wherein, the pump gas rate of oxygenation pump reduces, can make vapor and oxygen-enriched air flow intensive mixing, and can slow down the rate of oxygen-enriched air flow direction new trend shell 10 in, make the user slowly experience moist pure oxygen clean air, effectively improve user's comfortable experience. In the embodiment, the pumping speed of the oxygenation pump can be reduced by 20%, the oxygen-enriched airflow can be ensured to carry water vapor to be discharged indoors, and moist clean air is provided for users.
Further, oxygenation fresh air conditioner still includes: the fresh air duct 20 is communicated with the outside, and is used for detecting the temperature of the outdoor environment, and the indoor temperature sensor is arranged on the casing and is used for detecting the temperature of the indoor environment. So, be equipped with outdoor temperature sensor in the one end of fresh air pipe 20 with outdoor environment intercommunication, can detect outdoor environment's air temperature to and be equipped with indoor temperature sensor on the casing, thereby can detect the room and can last carry oxygen-enriched wind and new trend to the room high-efficiently.
Specifically, the controller is configured to control the dehumidifying assembly 40 to start to heat the oxygen-enriched air flow in the oxygen increasing cavity 30 and control the fresh air inlet 11 and the oxygen-enriched air inlet 12 to open to allow fresh air and oxygen-enriched air to enter the fresh air housing 10 when it is determined that the temperature value detected by the outdoor temperature sensor is less than the preset temperature threshold value or the temperature difference value between the temperature value detected by the outdoor temperature sensor and the temperature value detected by the indoor temperature sensor is greater than the preset temperature difference threshold value.
That is to say, when the temperature value detected by the outdoor temperature sensor is smaller than the preset temperature threshold, or the temperature difference between the temperature value detected by the outdoor temperature sensor and the temperature value detected by the indoor temperature sensor is greater than the preset temperature difference threshold, both of the above two cases can indicate that the outdoor temperature is relatively low, and if the fresh air channel is opened at this time, the outdoor fresh air flow is released to the indoor, which may cause the problem of large indoor temperature fluctuation.
Therefore, when the arbitrary one condition in the above-mentioned two kinds of condition appears, controller control dehumidification subassembly 40 starts, make dehumidification subassembly 40 can heat the oxygen boosting air current in oxygenation chamber 30, at this moment, it needs to be noted that, oxygenation device is in operating condition and oxygenation air intake 12 and new trend air intake 11 are in the open mode, thus, the oxygen boosting air current carries a large amount of heats and carries out the heat exchange in getting into new trend shell 10 together with the new trend, and under the drive operation of new trend fan, can release the oxygen boosting new trend of mixing to indoor smoothly, make the temperature of indoor air rise, realize the effect of constant temperature new trend, can effectively improve the influence to indoor temperature after outdoor new trend introduces.
And, the controller is configured to control the dehumidifying component 40 to start to dry and regenerate the moisture adsorbed by the dehumidifying component 40 when determining that the temperature value detected by the outdoor temperature sensor is greater than the preset temperature threshold value and the humidity value detected by the humidity sensor is greater than the first preset humidity threshold value.
