Detailed Description
Fig. 1 is a schematic structural view of an air conditioner indoor unit 1 according to an embodiment of the present invention.
Referring to fig. 1, an indoor unit 1 of a floor type air conditioner may generally include a casing in which a first chamber 10 and a second chamber 20, which may be in controlled communication, may be defined. Specifically, a supply air outlet 201 and a return air outlet 202 which can be controlled to be opened can be arranged between the first chamber 10 and the second chamber 20 so as to communicate the first chamber 10 and the second chamber 20. A fan 101 and a heat exchanger 102 are provided in the first chamber 10 to form a heat exchange air flow of which temperature is changed therein. A clothes drying device is provided in the second chamber 20 to place wet clothes to be dried. In particular, the indoor unit 1 has a plurality of clothes drying modes, and may specifically include: a drying and drying mode and a condensing and drying mode.
Fig. 2 is a schematic air path diagram of the air conditioner indoor unit 1 according to an embodiment of the present invention when operating in the drying and drying mode or the condensing and drying mode.
Referring to fig. 2, the blower 101 is configured to induce a heat exchange airflow in the first chamber 10 into the second chamber 20 through the blowing port 201 in the drying mode or the condensing drying mode, and to induce the heat exchange airflow into the first chamber 10 through the return port 202 after passing through the drying device disposed in the second chamber 20. Preferably, the drying device may be disposed at an intermediate position of the second chamber 20 to achieve an optimal drying effect.
The heat exchanger 102 may be controlled to cool or to heat. Further, the indoor unit 1 may be configured to switch between the drying and drying mode and the condensing and drying mode by adjusting the operation state of the heat exchanger 102.
That is, the indoor unit 1 of the present invention may form a cooling or heating heat exchange airflow that circulates between the first chamber 10 for forming the heat exchange airflow and the second chamber 20 for placing the wet laundry, so as to continuously send the heat exchange airflow in the first chamber 10 into the second chamber 20 and make the heat exchange airflow flow back into the first chamber 10 after passing through the clothes drying device in the second chamber 20, so as to take away the moisture in the air with relatively high humidity in the clothes drying device in the second chamber 20, and thus dry the wet laundry in the second chamber 20.
Further, in some embodiments of the present invention, the interior of the housing has a partition plate 100 horizontally disposed to divide the interior space thereof into upper and lower portions, i.e., into the first chamber 10 and the second chamber 20. Preferably, the first chamber 10 may be disposed above the second chamber 20.
Further, the supply air opening 201 may be disposed at the front of the partition plate 100 and downstream of the blower 101, and the return air opening 202 may be disposed at the rear of the partition plate 100 and upstream of the blower 101. That is, the supply air opening 201 may be preferably disposed downstream of the blower 101 and the heat exchanger 102, and the return air opening 202 may be preferably disposed upstream of the blower 101 and the heat exchanger 102, so that the heat exchange airflow formed in the first chamber 10 can directly flow to and flow into the second chamber 20 in the shortest time, thereby providing a flow path with a simple loop shape to the heat exchange airflow, avoiding multiple turns during the flowing process, and preventing the flow speed and the air volume from being reduced.
Specifically, in some embodiments of the present invention, when the indoor unit 1 operates in the drying and drying mode, the heat exchanger 102 is controlled to continuously heat, so that at least a portion of the air in the first chamber 10 continuously flows through the heat exchanger 102 under the action of the fan 101 and is heated to form a drying air flow, and the drying air flow can continuously enter the second chamber 20 through the air supply opening 201 under the blowing action of the fan 101 to dry the clothes in the drying device.
Further, in some embodiments of the present invention, when the indoor unit 1 operates in the condensation drying mode, the heat exchanger 102 is controlled to alternately heat and cool, and heat at least a portion of the air in the first chamber 10 continuously flowing therethrough under the action of the fan 101 to form a drying air flow when heating, and cool at least a portion of the drying air flow continuously flowing therethrough under the action of the fan 101 and flowing back from the second chamber 20 to the first chamber 10 under the action of the fan 101 to condense and separate out moisture in the at least a portion of the drying air flow when cooling.
That is, in the condensation drying mode, the heat exchanger 102 may heat the normal or low temperature air to form a high temperature drying air stream if necessary, and may cool the hot and humid air flowing therethrough to dry the hot and humid air if necessary.
Therefore, the indoor unit 1 of the present invention does not need to be specially provided with an additional drying device or a complicated air path, and only needs to add a containing device for placing damp clothes in the indoor unit of the floor air conditioner, and can realize the clothes drying function by utilizing the inherent structure of the floor air conditioner and the necessary original devices in the heat exchange system thereof.
Further, in some embodiments of the present invention, the heat exchanger 102 may be configured to first continue heating for a first time and then controllably switch to continue cooling for a second time in the condensation drying mode. Specifically, a first time and a second time consecutive thereto may together form an operation period when the indoor unit 1 operates in the condensation drying mode. Further, the first time is longer than the second time in each operating cycle.
That is, the indoor unit 1 first continuously operates the heating mode for the first time to continuously supply the high-temperature drying air flow to the second chamber 20 and take away moisture of the damp laundry in the drying device. After the high-temperature drying is continued for the first time, the moisture in the high-temperature drying airflow is close to or saturated. At this time, the heat exchanger 102 is switched to the cooling mode, and then the hot and humid air flowing back from the second chamber 20 to the first chamber 10 contacts the heat exchanger 102 to be cooled to separate out condensed water, and the condensed water is condensed on the surface of the heat exchanger 102, thereby realizing dehumidification. After operating in the cooling mode for the second time, the humidity of the drying airflow is greatly reduced. At this time, the heat exchanger 102 is switched to the heating mode again, that is, the indoor unit 1 enters the second (or next) operation cycle in the condensation drying mode, so as to cycle back and forth until the damp clothes in the clothes drying device are completely dried.
Specifically, in some embodiments of the present invention, the first time may be 4 minutes, 5 minutes, or 6 minutes, etc., and the second time may be set to 2 minutes, 3 minutes, or 4 minutes, etc., accordingly. The duration of the second time can be increased along with the increase of the first time, and shortened along with the decrease of the first time, and is always smaller than the duration of the first time corresponding to the second time, so that the utilization rate of the cold or heat generated by the heat exchanger 102 in the process of cooling or heating can be always kept at a higher level.
In some embodiments of the present invention, the air supply opening 201 and the air return opening 202 are respectively provided with a temperature sensor. Further, the indoor unit 1 may be configured to finish drying when a temperature difference between the drying air flowing through the air supply opening 201 and the drying air flowing through the air return opening 202 is less than a preset temperature difference value in the condensation drying mode and the drying mode.
In some embodiments of the present invention, the indoor unit 1 may have a determination module to determine the drying condition. Specifically, in the condensing drying mode, the indoor unit 1 may determine a temperature difference of the drying airflow passing through the air supply opening 201 and the air return opening 202 in the first time within one operation period through the determination module. That is, when the indoor unit 1 heats the heat exchanger 102, the temperature values of the drying airflow at the air supply opening 201 and the air return opening 202 are continuously detected, and the difference between the temperature of the airflow before drying and the temperature of the airflow after drying is compared. When the clothes in the clothes drying device are dried, because the clothes do not contain or only contain less moisture, the influence on the temperature of the drying airflow passing through the clothes drying device is small, therefore, when the temperature difference of the drying airflow before and after drying is smaller than a preset temperature difference value, the drying can be directly judged to be finished, thereby simplifying the drying judgment condition of the indoor unit 1 and facilitating the operation. In some embodiments of the present invention, the predetermined temperature difference may be 1 ℃ or 2 ℃.
Further, the temperature sensor at the air supply opening 201 continuously detects the temperature of the drying airflow when the indoor unit 1 operates in the drying mode and the condensing mode to determine whether the indoor unit 1 meets the drying gear set by the user. Specifically, the indoor unit 1 may have a plurality of drying gear positions of various strengths in any drying mode, for example, may be strong, standard, soft, etc. Accordingly, when the indoor unit 1 operates the drying function at different gear positions, the temperature of the drying airflow formed in the first chamber 10 is also different. For example, the drying airflow temperature in the strong gear may be 70 ℃, the drying airflow temperature in the standard gear may be 60 ℃, the drying airflow temperature in the soft gear may be 50 ℃, and the like.
Fig. 3 is a schematic air path diagram of an air conditioner indoor unit according to an embodiment of the present invention when the air conditioner indoor unit operates in a heat exchange mode.
Referring to fig. 3, in some embodiments of the present invention, the portion of the housing defining the first chamber 10 is provided with an air inlet 103 and an air outlet 104 which can be opened or closed in a controlled manner, and the air inlet 103 and the air outlet 104 are also vents for exchanging air with the surrounding environment, which are inherent in a general vertical air conditioner.
Further, the indoor unit 1 has a heat exchange mode. The heat exchange mode may generally include a cooling mode and a heating mode. The air inlet 103 and the air outlet 104 are controlled to be opened in the heat exchange mode, and the air supply outlet 201 and the air return outlet 202 are controlled to be closed in the heat exchange mode, so that the ambient air is allowed to enter the first chamber 10 under the action of the fan 101 and flow out of the first chamber 10 after flowing through the heat exchanger 102 to form a heat exchange air flow.
Specifically, in some embodiments of the present invention, the intake vent 103 and the exhaust vent 104 may be disposed on two opposite sidewalls of the first chamber 10. The supply air port 201 may be provided on the partition plate 100 near the air outlet 104, and the return air port 202 may be provided on the partition plate 100 near the air inlet 103.
The vertical air conditioner of the present invention has a first chamber 10 for installing a blower 101 and a heat exchanger 102 at an upper portion thereof, and a second chamber 20 for placing a drying device at a lower portion thereof. Accordingly, the intake and exhaust ports 103 and 104 on the housing may be provided at positions corresponding to the first chamber 10 at the upper portion thereof. Therefore, when the indoor unit 1 of the air conditioner works in a heat exchange mode, the blown heat exchange airflow can cover the main height area of indoor user activity, and the heat exchange efficiency of the air conditioner during refrigeration or heating is ensured.
The vertical indoor unit 1 has a high air outlet position to blow cooling air or heating air to the indoor environment due to the inherent structure. The inventor of the present invention has creatively realized that the vertical volume of the indoor unit 1 of the floor air conditioner has a smaller visual and practical impact on the indoor floor space than the horizontal volume by making an intensive study on the functional characteristics of the floor air conditioner. Further, the inventor also recognizes that the indoor unit 1 has a larger space in the lower casing and a low utilization rate because some heat exchange systems or electric control systems of the indoor unit itself require a certain installation space. Therefore, the clothes drying device is directly arranged on the lower part of the indoor unit 1, so that the original structure of the indoor unit 1 can be utilized to the maximum degree, the drying function is realized, and the practicability of the air conditioner is greatly improved.
Further, the basic heat exchange function of the indoor unit 1 having the drying function is not affected by the drying function. When the indoor unit 1 operates in the heat exchange mode, the air supply opening 201 and the air return opening 202 are controlled to be closed to completely isolate the first chamber 10 from the second chamber 20, and the clothes drying device in the second chamber 20 does not affect the air flow in the first chamber 10 and cannot obstruct the flow speed and the flow direction of the heat exchange air flow flowing in the first chamber 10 at this time.
Accordingly, the air inlet 103 and the air outlet 104 are controlled to be closed in both the drying and drying mode and the condensing and drying mode, so that the housing is closed. The air supply opening 201 and the air return opening 202 are controlled to be opened in both of the drying and drying mode and the condensing and drying mode. Thereby, the drying air flow is continuously made to enter the second chamber 20 from the first chamber 10 via the controlled opening supply air opening 201 and to enter the first chamber 10 from the second chamber 20 via the controlled opening return air opening 202 in the closed housing.
That is, when the indoor unit 1 operates in the condensation drying mode or the drying mode, the casing is in a closed state to be isolated from the indoor environment. The air inlet 103 and the air outlet 104 are both controlled to be closed in the drying mode to prevent the indoor unit 1 from performing air exchange with the indoor environment, and the air supply opening 201 and the air return opening 202 are controlled to be opened in the drying mode to allow the first chamber 10 and the second chamber 20 to perform air exchange. Therefore, the humid and hot air can be prevented from flowing out of the indoor unit 1 to the indoor environment, the air conditioner which is drying clothes can not affect the temperature and the humidity of the indoor environment, and the indoor unit 1 can be effectively prevented from bringing inconvenience or uncomfortable feeling to indoor users when being in a clothes drying mode.
Specifically, after the user switches the indoor unit 1 to the drying mode or the condensing drying mode through a control input terminal such as a remote controller, the air inlet 103 and the air outlet 104 are controlled to be closed. At this time, the casing is in a closed state, and the air inside the indoor unit 1 cannot flow out to the indoor environment through the air inlet 103 and/or the air outlet 104. Further, in the condensation drying mode, the first chamber 10 and the second chamber 20 in the closed housing form a circulation air path through the air supply opening 201 and the air return opening 202, so that moisture in the air with higher humidity in the second chamber 20 is continuously carried out by the high-temperature dry air entering the second chamber 20 from the first chamber 10 during heating by the heat exchanger 102, and the wet and hot air with moisture close to saturation is formed, and then the wet and hot air completely flows back into the first chamber 10 and contacts the heat exchanger 102 switched to the cooling mode. The damp and hot air is cooled to separate out condensed water, the condensed water is condensed on the surface of the heat exchanger 102, the air with the reduced humidity continuously and circularly flows until the air is condensed to the drying airflow and is completely dried, and the air is heated again in the next operation period to continuously dehumidify and dry clothes.
Fig. 4 is a schematic air-path diagram of an indoor unit of an air conditioner according to an embodiment of the invention when the indoor unit operates in a heating clothes drying mode.
Referring to fig. 4, in some embodiments of the invention, the portion of the housing defining the second chamber 20 is provided with a controlled opening vent 203. Accordingly, the plurality of drying modes of the indoor unit 1 further include a heating drying mode. The air inlet 103, the air supply opening 201 and the air outlet 203 are configured to be controlled to open in the heating clothes drying mode, so as to allow ambient air to enter the first chamber 10 through the air inlet 103 to form a drying air flow, and allow the drying air flow to enter the second chamber 20 through the air supply opening 201 and flow out to the ambient environment through the air outlet 203 after flowing through the clothes drying device.
That is, the indoor unit 1 of the present invention also has a function of simultaneously performing a drying function and a humidifying function. When the indoor environment is too dry, the indoor unit 1 can dry clothes and can connect the completely closed shell with the indoor environment through the air inlet 103 and the air outlet 203. Therefore, the indoor ambient air can continuously enter the first chamber 10 and be heated in the first chamber 10 to form the drying air flow. Further, after the drying air flow enters the second chamber 20 and passes through the clothes drying device, the drying air flow with higher humidity can flow out from the air outlet 203, so as to supply the water vapor taken away from the clothes drying device to the ambient air, so as to enhance the humidity of the indoor environment.
In some embodiments of the present invention, the clothes drying apparatus includes a receiving tub 204, and a plurality of ventilation holes are formed on a wall of the receiving tub 204. At least part of the tub wall of the accommodating tub 204 and at least part of the housing together define a drying air duct to guide at least part of the drying air flow entering the second chamber 20 from the air supply opening 201 to surround the circumference of the accommodating tub 204 and enter the accommodating tub 204 through the vent hole.
That is, a part of the heat exchange air flow entering the second chamber 20 from the first chamber 10 enters the accommodating tub 204 through the plurality of ventilation holes on the tub wall near the air supply opening 201 to contact with the moist air and/or the moist laundry, and another part of the heat exchange air flow flows from top to bottom below the accommodating tub 204, at the bottom of the second chamber 20, along the drying air duct defined between the tub wall and the part of the housing forming the second chamber 20, and enters the accommodating tub 204 through the plurality of ventilation holes far from the air supply opening 201. Therefore, the circumferential side and the bottom of the wet clothes in the accommodating barrel 204 can be contacted with the dry heat exchange airflow, so that the clothes drying efficiency of the indoor unit 1 is improved.
Further, the receiving tub 204 may be configured to rotate. For example, the accommodating tub 204 can be driven by the additional driving mechanism to perform a motion similar to the rotation of the drum of the washing machine, so that the contact area between the damp clothes therein and the heat exchange airflow entering the second chamber 20 from the first chamber 10 for drying the clothes is increased, the clothes drying efficiency is improved, and the clothes drying effect is enhanced.
In some embodiments of the invention, the indoor unit 1 further comprises at least one drip tray. A drip tray is disposed below the heat exchanger 102 to collect condensed water formed on the outer surface of the heat exchanger 102. One or more water-receiving trays can be provided, and the number and the size of the water-receiving trays are required to ensure that condensed water condensed on the heat exchanger 102 can be collected when the condensed water falls down.
Fig. 5 is a schematic diagram of an air conditioner according to an embodiment of the present invention. Referring to fig. 5, the air conditioner includes an indoor unit 1 and an outdoor unit, and a heat exchanger 102 and a fan 101 are disposed in the indoor unit 1, wherein the heat exchanger 102 may be communicated with a heat exchange system of the outdoor unit through a refrigerant pipeline. The outdoor unit is internally provided with a compressor, a four-way valve, an outer heat exchanger, an outer fan, an outer throttling device and the like.
When the indoor unit 1 works in a heating mode of heat exchange modes, a high-temperature and high-pressure refrigerant flows out of the compressor, is guided by the four-way valve, firstly flows into the heat exchanger 102 of the indoor unit 1 to realize heating, and then returns to the compressor through the outer throttling device and the outer heat exchanger in sequence. When the indoor unit 1 works in a refrigeration mode in the heat exchange mode, the four-way valve is reversed, a high-temperature and high-pressure refrigerant flows out of the compressor, is guided by the four-way valve, is sequentially subjected to heat release by the outer heat exchanger, is subjected to pressure reduction and throttling by the outer throttling device, enters the heat exchanger 102 of the indoor unit 1 to realize refrigeration, and then flows back to the compressor.
Particularly, when the indoor unit 1 operates in a drying and drying mode, a condensing and drying mode, or a heating and drying mode, a flow direction of a refrigerant in a heat exchange system of the air conditioner is the same as that of the heating mode in which the indoor unit 1 operates in the heat exchange mode. That is, the control method of the indoor unit 1 in the multiple clothes drying modes does not need to be additionally provided, and the function of drying clothes can be basically realized only by the original control method of the air conditioner, so that the heat exchange mode and the clothes drying mode can be rapidly switched without other additional complex structures, and the operation is simple and convenient.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
