The utility model provides a heating element 14 can use in the anti-cold wind stage of air conditioner, and heat transfer wind channel 101 does not provide the heat this moment, or the heat that provides is not enough, and at this moment, can carry out the heat through heating element 14 and supply to can realize indoor temperature's promotion fast. Of course, the technical solution to be protected in the present invention is not limited thereto, the heating assembly 14 of the present invention can be applied to other situations as well, for example, when the heat provided through the heat exchange air duct 101 is insufficient (for example, in defrosting or other modes), the heating assembly 14 can be utilized to provide radiant heat, supply heat to the indoor environment, and directly heat the indoor air through the heating assembly 14, so as to maintain the temperature of the indoor environment better.
Wherein, the heating component 14 of the present invention can be configured to directly radiate heat to the radiation opening 105; it may also be arranged to reflect heat from the heating element 14 towards the radiation opening 105 by reflection from the interior surface of the radiation heating cavity 104; it may also be provided that the interior surface of the radiant heating cavity 104 reflects heat from the heating assembly 14 toward the radiation opening 105 while the heating assembly 14 radiates heat directly toward the radiation opening 105.
Wherein, the heating component 14 of the present invention can be configured as a radiation heating structure, for example, the heating component 14 can include a carbon fiber electrical heating tube, a quartz electrical heating tube, etc.
The heating assembly 14 of the utility model can independently heat the indoor, that is, the heating assembly 14 heats the indoor radiation heat, thereby heating the indoor environment, at this time, the radiation heating cavity 104 where the heating assembly 14 is located can be completely separated from the heat exchange air duct 101; in addition, the airflow driving part 13 of the heat exchange air duct 101 can drive the airflow to circulate in the radiation heating cavity 104, so that the airflow can exchange heat with the heating component 14, the heat exchange efficiency and effect are improved, and at the moment, the radiation heating cavity 104 and the heat exchange air duct 101 can be communicated with each other; additionally, a separate drive mechanism may be provided to drive the airflow within the radiant heating chamber 104 so that the room temperature can be regulated by the heating assembly 14 alone. To this end, the present invention provides different embodiments.
With reference to fig. 1-4, in some embodiments of the invention, the radiant heating chamber 104 has a vent 106, the vent 106 being adapted to communicate with the heat exchange duct 101. Wherein, the ventilation opening 106 is suitable for being communicated with the heat exchange air duct 101, and at least comprises the following scheme: it may be provided that the vent 106 of the radiant heating chamber 104 is always in communication with the heat exchange air duct 101, that is, the radiant heating chamber 104 is always in communication with the heat exchange air duct 101; it is also contemplated that the vent 106 of the radiant heating chamber 104 is selectively in communication with and out of communication with the heat exchange air duct 101, i.e., under certain conditions, the vent 106 of the radiant heating chamber 104 is in communication with the heat exchange air duct 101. At this time, since the radiation heating cavity 104 is communicated with the heat exchange air duct 101 through the ventilation opening 106, the air flow in the heat exchange air duct 101 can be sent out through the radiation heating cavity 104, and the air flow can be heated by the heating assembly 14 when passing through the radiation heating cavity 104, so that the temperature of the air flow sent to the indoor space can be increased, and under some conditions, the ventilation opening 106 of the radiation heating cavity 104 is not communicated with the heat exchange air duct 101, and at this time, when the heating assembly 14 is started, the heating assembly 14 can radiate heat outwards.
Because the radiation heating cavity 104 of the present invention has the ventilation opening 106, the radiation heating cavity 104 can be communicated with the heat exchange air duct 101 through the ventilation opening 106, and the air flow can pass through the radiation heating cavity 104 during the air flow circulation process. For only depending on radiation heating, the geothermal energy of the heating component 14 after being communicated with the heat exchange air channel 101 can rapidly flow to each indoor corner under the action of air flow circulation, so that the uniformity of the indoor environment temperature can be effectively improved, and the heating and temperature maintaining effects on the indoor environment are improved.
Alternatively, the opening and closing of the ventilation opening 106 can be adjusted by providing the radiation wind deflector 15. Specifically, in some embodiments of the present invention, the vent 106 is provided with a radiation air deflector 15, the radiation air deflector 15 is movable between an open position and a closed position, the radiation air deflector 15 opens the vent 106 in the open position to communicate the radiation heating chamber 104 with the heat exchange air duct 101, and the radiation air deflector 15 closes the vent 106 in the closed position to isolate the radiation heating chamber 104 from the heat exchange air duct 101. In the using process, the radiation air deflector 15 can be opened and closed as required, and when the air flow of the heat exchanging air duct 101 needs to be heated through the radiation heating cavity 104 and the heating assembly 14, the radiation air deflector 15 can be opened, so that the air flow of the heat exchanging air duct 101 can be heated through the heating assembly 14 and sent out through the radiation opening 105 after being heated; when the air flow in the heat exchange air duct 101 does not need to be heated through the radiation heating cavity 104 and the heating element 14, the radiation air deflector 15 can be closed, and the air flow in the heat exchange air duct 101 does not pass through the radiation heating cavity 104 any more.
Therefore, by providing the radiant air guide 15 at the vent 106, different heating patterns can be achieved by opening and closing the radiant air guide 15. The selection can be performed according to actual needs, so as to meet different working requirements in the air-conditioning room and meet the requirements of users on the indoor unit 100 of the air conditioner.
For example, when the radiation air deflector 15 is closed, the heat exchange air duct 101 and the radiation heating cavity 104 are separated, and in the operation process of the air flow driving member 13, the air flow in the heat exchange air duct 101 circulates in the heat exchange air duct 101, enters the heat exchange air duct 101 from the air return opening 102 of the heat exchange air duct 101, exchanges heat with the indoor heat exchanger 12 in the heat exchange air duct 101, and then is sent to the indoor through the air supply opening 103, so as to adjust the temperature of the indoor heat exchanger 12. The heating assembly 14 can be in an open state or a closed state, and if the heating assembly 14 is in the open state, the heating assembly 14 radiates heat to the room through the radiation opening 105, so that the room is heated by the combined action of the heat exchange channel, the radiation heating cavity 104 and the heating assembly 14.
For another example, when the radiation air deflector 15 is opened, the heat exchange air duct 101 communicates with the radiation heating cavity 104, and during the operation of the air flow driving member 13, the air flow in the heat exchange air duct 101 can flow through the heat exchange air duct 101 and can enter the radiation heating cavity 104. When the air supply outlet 103 of the heat exchange air duct 101 is opened, the air flow can enter the heat exchange air duct 101 from the air return inlet 102, after heat exchange is performed between the heat exchange air duct 101 and the indoor heat exchanger 12, a part of the air flow can be sent to the indoor through the air supply outlet 103, and the other part of the air flow can enter the radiation heating cavity 104 and be sent to the indoor through the radiation outlet 105, at this time, if the heating assembly 14 is in an opened state, the heating assembly 14 can heat the air flow flowing through the radiation heating cavity 104, so that indoor heating is performed through the combined action of the heat exchange channel, the radiation heating cavity 104 and the heating assembly 14; when the air supply opening 103 of the heat exchange air duct 101 is closed, the air flow can enter the heat exchange air duct 101 from the air return opening 102, after heat exchange is carried out between the indoor heat exchanger 12 and the heat exchange air duct 101, the air flow can enter the radiation heating cavity 104 due to the closing of the air supply opening 103, and the air flow is sent to the indoor space through the radiation opening 105, at the moment, if the heating assembly 14 is in an opening state, the heating assembly 14 can heat the air flow flowing through the radiation heating cavity 104, and therefore indoor heating is achieved through the combined action of the heat exchange channel, the radiation heating cavity 104 and the heating assembly 14.
In addition, the utility model discloses in can also set up the proportion regulation structure, through the proportion regulation structure, can adjust the wind channel in get into radiation heating chamber 104 and be sent to the proportion of supply-air outlet 103 to adjust according to actual need. Optionally, the radiation air deflector 15 of the present invention may be configured to have such a ratio adjusting structure, for example, a part of the air flow sent into the heat exchange air duct 101 from the air return opening 102 is sent out through the air supply opening 103 by the radiation air deflector 15, and another part of the air flow enters the radiation heating cavity 104 and is sent out from the radiation opening 105, at this time, the ratio of the air flow sent out from the air supply opening 103 and from the radiation opening 105 can be adjusted by adjusting the radiation air deflector 15, thereby further facilitating the adjustment of the indoor heat exchanger 12.
Optionally, the radiation air deflector 15 is configured to be rotatable between an open position and a closed position, and the radiation air deflector 15 is inclined toward the vent 106 relative to the air outlet direction of the heat exchange air duct 101 in the open position. The opening and closing of the radiation air deflector 15 can be realized through rotation, the control of the radiation air deflector 15 is simplified, in addition, when the re-radiation air deflector 15 is opened, the radiation air deflector 15 has a guiding function, and when the air flow of the heat exchange channel passes through the radiation air deflector 15, the air flow flows to the radiation heating cavity 104 under the guiding function of the radiation air deflector 15, so that more air flow can be introduced into the radiation heating cavity 104, and the heating effect of the heating component 14 is improved.
The rotation central axis of the radiation air deflector 15 is adjacent to the downstream side of the vent 106, and in the rotation process of the radiation air deflector 15, when the radiation air deflector 15 is in the open position, the radiation air deflector 15 is inclined towards the vent 106 in the air outlet direction of the heat exchange channel, wherein the rotation central axis and the end edge of the radiation air deflector 15 are spaced by a preset distance, and a groove can be arranged on the downstream side of the vent 106, so that in the rotation process of the radiation air deflector 15, the groove can give way to the radiation air deflector 15 to facilitate the smooth rotation of the radiation air deflector 15, wherein the inner surface of the groove can be set into an arc shape matched with the shape of the radiation air deflector 15, so that the relative sealing between the radiation air deflector 15 and the groove can be conveniently realized, and the flow guiding effect of the radiation air deflector 15 on airflow is improved.
Alternatively, with the radiant air deflector 15 in the open position, in the cross section of the air conditioning indoor unit 100: the axis of the heating assembly 14 and the upstream side of the vent 106 are located on a first straight line L1, and one end of the radiation air deflector 15 extends out of the first straight line L1 and has a first distance B from the first straight line L1. At this time, one end of the radiation wind deflector 15 may shield the upstream side of the vent 106.
Alternatively, with the radiant air deflector 15 in the open position, in the cross section of the air conditioning indoor unit 100: the axis of the heating assembly 14 and the downstream side of the vent 106 are located on a second straight line L2, and the other end of the radiation air deflector 15 extends out of the second straight line L2 and has a second distance C from the second straight line L2. At this time, the other end of the radiation wind deflector 15 may shield the downstream side of the vent 106. Light leakage from the vent can be reduced or avoided by the shielding effect of the radiation air deflector 15.
The upstream side and the downstream side of the vent 106 are relative to the air outlet direction in the heat exchange air duct 101, and in the air flow circulation process in the heat exchange air duct 101, the air flow passes through the upstream side of the vent 106 and then passes through the downstream side of the vent 106.
Due to the shielding effect of the radiation air deflector 15, the heat radiated by the heating assembly 14, if passing through the ventilation opening 106, will be shielded by the radiation air deflector 15, and therefore, the heat of the heating assembly 14 will not be radiated directly to the air duct wall of the heat exchange air duct 101. Therefore, the heat radiated by the heating component 14 can be reduced or prevented from being directly applied to the heat exchange air duct 101, the temperature rise of the wall surface in the heat exchange air duct 101 is reduced, the plastic material in the indoor air conditioner 100 is prevented from being easily aged due to overhigh temperature, the service life of the indoor air conditioner 100 is prolonged, the service cycle of the indoor air conditioner 100 is prolonged, and the maintenance cost of the indoor air conditioner 100 is reduced.
Further, the first pitch B and the second pitch C are each in a range of 3mm to 10 mm, for example, the first pitch B and the second pitch C are set to 3mm, 5mm, 7 mm, 10 mm, or the like. Therefore, the shading effect of the radiation air deflector 15 on the vent 106 can be further improved, specifically, in general, only the first distance B and the second distance C need to exist, and light transmitted by the vent 106 can be shaded by the radiation air deflector 15, but in the actual production process, due to reasons such as insufficient assembly precision, assembly error accumulation can be caused, when the first distance B and the second distance C are too small, the insufficient assembly precision can cause light to leak out of the radiation air deflector 15, so that the shading effect of the radiation air deflector 15 is weakened, therefore, the light leakage effect of the radiation air deflector 15 can be improved by setting the first distance B and the second distance C to be larger than 3 millimeters. In addition, when first interval B and second interval C were too big, the space that radiation aviation baffle 15 occupied was too big, leads to radiation aviation baffle 15 to occupy too much space easily, consequently, the utility model discloses in the upper limit to first interval B and second interval C has carried out the restriction. The first spacing B and the second spacing C are arranged in the range of 3mm to 10 mm, so that the light leakage releasing performance of the radiation air deflector 15 can be effectively improved, the dead space occupied by the radiation air deflector 15 can be reduced, and the performance of the indoor unit of the air conditioner can be effectively improved.
Of course, in some cases (e.g., high assembly accuracy, large enough overall size of the air conditioning indoor unit, etc.), the first distance B and the second distance C in the present invention may be set to be less than 3mm (e.g., 1 mm) or more than 10 mm (e.g., 15 mm), and the first distance B and the second distance C may be set to be the same or different.
Optionally, the inner wall surface of the heat exchange air duct 101 is provided with a recess 107, the recess 107 is located upstream of the vent 106, the radiation air deflector 15 is embedded in the recess 107 in the closed position, and the surface of the radiation air deflector 15 is flush with the inner wall surface of the heat exchange air duct 101. At this time, when the radiation air deflector 15 is closed, the end of the radiation air deflector 15 is embedded into the recess 107, and the radiation air deflector 15 is substantially flush with the inner wall surface of the heat exchange air duct 101, so that the obstruction of the radiation air deflector 15 to the air flow can be reduced or avoided, the air flow in the heat exchange air duct 101 can pass through more smoothly, the stability of the air flow circulating in the heat exchange air duct 101 is improved, and the air supply amount is increased.
Wherein, the radiation air deflector 15 is flush with the inner wall surface of the heat exchange air duct 101, and may include: the radiation air deflector 15 and the inner wall surface of the heat exchange air duct 101 are positioned on the same plane or the same curved surface; or the end thickness of the radiation guide plate 15 is the same as the depth answer of the recess 107. The radiation air deflector 15 may not be completely flush with the inner wall surface of the heat exchange air duct 101 at the closed position due to the machining precision and the like, and the radiation air deflector 15 is not completely flush with the inner wall surface of the heat exchange air duct 101 due to the machining error and the like, which also falls within the protection scope of the present application.
In some embodiments of the present invention, the airflow driving member 13 is a cross-flow wind wheel, wherein, in the air outlet section of the heat exchange air duct 101, the air volume at the air duct side wall connected to the volute tongue is smaller, and relatively speaking, the air volume at the air duct wall opposite to the volute tongue is larger. Therefore, the utility model discloses can locate vent 106 in the air-out section of heat transfer wind channel 101 on the wind channel wall relative with the volute tongue, like this, in the use, the air current in the heat transfer wind channel 101 gets into more easily and enters into radiation heating chamber 104 through vent 106 in to improve the amount of wind to the interior air supply of radiation heating chamber 104, improved the performance of air conditioner.
Alternatively, the casing 11 includes the plastic casing 111 and the reflection cover 112, and by providing the plastic casing 111, the weight and cost of the air conditioning indoor unit 100 can be reduced. The reflective hood 112 is connected to the bottom of the plastic housing 111, the reflective hood 112 forms the radiation heating cavity 104 therein, and the reflective hood 112 is configured and adapted to reflect heat of the heating assembly and radiate from the radiation opening 105 to the outside of the housing 11, wherein the minimum distance a between the reflective hood 112 and the plastic housing 111 is not less than 3 mm. By separating the plastic casing 111 from the reflection cover 112, the plastic casing 111 can be prevented from being affected by high temperature on the reflection cover 112, so that the problem that the plastic casing 111 is easy to age due to high temperature is avoided, the stability of the indoor air conditioner 100 is improved, and the service life of the indoor air conditioner 100 is prolonged.
In the air conditioning indoor unit 100, the air outlet 103 is used to blow air into the room, and therefore the position where the air outlet 103 is installed is generally a position where the indoor ambient temperature can be more easily adjusted. Optionally, the radiation opening 105 of the present invention is disposed adjacent to the air supply opening 103, so that the heat radiated by the heating assembly 14 can be more easily transported toward a predetermined direction, thereby improving the adjusting effect of the heating assembly 14 on the indoor environment temperature.
Alternatively, during use, static electricity or the like may be generated by the heat radiated from the heating assembly 14, and for this reason, the radiation heating cavity 104 is disposed at the bottom of the housing 11, and the radiation opening 105 is opened downward. In this way, the heat radiated from the heating unit 14 is sent to the lower side of the indoor unit 100, so that the heating unit 14 is prevented from radiating heat directly to the user or user, and the comfort of the indoor unit 100 is effectively improved.
