The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The following describes a specific structure of a drying apparatus 10 for a dishwasher according to an embodiment of the present invention with reference to fig. 1 to 3.
As shown in fig. 1 to 3, the drying apparatus 10 for a dishwasher according to an embodiment of the present invention includes a body 100 and a heat exchanger 130, a condensing duct 110 is defined in the body 100, the condensing duct 110 has a first air inlet 111 and a first air outlet 112, the first air inlet 111 is adapted to communicate with the washing chamber 20 of the dishwasher 1, the first air outlet 112 communicates with the outside of the washing chamber 20, the heat exchanger 130 is disposed in the condensing duct 110 between the first air inlet 111 and the first air outlet 112, and the heat exchanger 130 is configured to exchange heat between air in the condensing duct 110 and outside air of the washing chamber 20. The main body 100 is provided with an auxiliary air inlet 113, the auxiliary air inlet 113 is respectively communicated with the outside of the condensation air duct 110 and the washing cavity 20, and the auxiliary air inlet 113 is positioned at the downstream of the heat exchanger 130 in the airflow flowing direction of the condensation air duct 110.
It should be noted that, during the operation of the dishwasher 1, a large amount of high-temperature and high-humidity air is generated in the washing chamber 20, and if such air is directly discharged to the outside of the washing chamber 20, the dishwasher 1 continuously discharges the high-temperature and high-humidity air in the operation engineering, so that the customer experience degree is greatly reduced, and therefore, the high-temperature and high-humidity air discharged from the washing chamber 20 needs to be condensed to be discharged. Because the heat exchanger in the drying device in the prior art mostly adopts the separation convection heat exchange of the cold air led into the room and the high-temperature and high-pressure air discharged from the washing cavity, the air flow passing through the heat exchanger still has moisture due to the limitation of the heat exchange mode, and the customer experience is reduced when the air flow is discharged into the external environment.
It will be appreciated that in the embodiment of the present invention, the high-temperature and high-humidity air flow in the dishwasher 1 enters the condensation duct 110 through the first air inlet 111, and the heat exchanger 130 is configured to exchange heat between the air in the condensation duct 110 and the air outside the washing chamber 20, that is, the heat exchanger 130 condenses the high-temperature and high-pressure air flow discharged into the condensation duct 110, thereby reducing the temperature of the high-temperature and high-pressure air flow to some extent. In addition, since the auxiliary air inlet 113 is disposed on the main body 100, that is, air in the external environment enters the condensation duct 110 through the auxiliary air inlet 113, and since the auxiliary air inlet 113 is located downstream of the heat exchanger 130 in the airflow direction of the condensation duct 110, that is, the airflow leaving the heat exchanger 130 is convected with the airflow entering the condensation duct 110 from the auxiliary air inlet 113. Because the air flow discharged through the heat exchanger 130 still has higher temperature and humidity than the air in the external environment, the air flow entering the condensation duct 110 from the auxiliary air inlet 113 can be condensed again on the air flow discharged through the heat exchanger 130, so that the temperature and humidity of the air flow discharged through the heat exchanger 130 are further reduced, and the air flow has lower temperature and humidity after leaving the drying device 10 from the first air outlet 112, thereby improving the user experience.
In summary, in the drying device 10 according to the embodiment of the present invention, the temperature and humidity of the air flow can be well reduced by the primary condensation of the air discharged from the washing chamber 20 of the dish washer 1 through the heat exchanger 130 and the secondary condensation of the auxiliary air flow, and the user experience can be improved by discharging such air flow to the external environment.
It should be noted that, in this embodiment of the present invention, the air flow discharged from the first air outlet 112 may be directly discharged to the outside (i.e. indoor environment) of the dishwasher 1, or the dishes in the washing chamber 20 may be dried by re-introducing the heated air into the washing chamber 20 after the dishes are washed by the dishwasher 1.
According to the drying device 10 for a dish washer, provided by the embodiment of the invention, as the auxiliary air inlet 113 positioned at the downstream of the heat exchanger 130 is arranged in the condensation air duct 110, the functions of primary condensation of the air flow discharged from the washing cavity 20 of the dish washer 1 through the heat exchanger 130 and secondary condensation of the auxiliary air inlet flow are realized, the temperature and the humidity of the air flow discharged from the washing cavity 20 of the dish washer 1 are well reduced through the secondary condensation, and the user experience is improved.
In some embodiments, as shown in fig. 3, the auxiliary intake vent 113 includes a plurality of intake vents 1131. It will be appreciated that if the auxiliary air inlet 113 is formed as an air inlet 1131 with a larger aperture, the air flow from the auxiliary air inlet 113 will be larger, and the air flow discharged from the heat exchanger 130 will be impacted more, and the larger impact will be very easy to cause the phenomenon that the heat exchange efficiency between the auxiliary air inlet and the air flow discharged from the heat exchanger 130 is underground. Therefore, in order to prevent the above phenomenon, the auxiliary air inlet 113 is provided with a plurality of air inlet holes 1131, so that the impact of the auxiliary air inlet on the air flow discharged from the heat exchanger 130 is smaller, the heat exchange between the auxiliary air inlet and the air flow discharged from the heat exchanger 130 is more uniform, and the humidity of the air flow discharged from the heat exchanger 130 is better reduced.
Advantageously, as shown in fig. 3, the auxiliary air inlet 113 includes air inlets 1131 that are arranged in a plurality of rows and columns or are distributed in a plurality of concentric circles, so that the heat exchange effect between the auxiliary air inlet and the air discharged from the heat exchanger 130 can be further improved. Of course, the air inlets 1131 may be formed in other irregular arrangements.
It should be noted that, the plurality of air inlets 1131 included in the auxiliary air inlet 113 are used for guiding the external air flow into the condensation duct 110, and the shape, size and number of the air inlets 1131 are not specifically limited herein, that is, a designer may arbitrarily design the shape, size and number of the air inlets 1131 according to actual needs.
In some embodiments, as shown in fig. 3, a baffle 114 corresponding to the auxiliary air inlet 113 is disposed in the condensation duct 110, and the baffle 114 is configured to prevent liquid droplets in the condensation duct 110 from flowing out of the auxiliary air inlet 113. It should be noted that, since the air discharged from the heat exchanger 130 may have small droplets, if no stop device is provided at the auxiliary air inlet 113, the small droplets may flow out from the auxiliary air inlet 113, so that the condensed water cannot enter the designated condensed water collecting container, and user experience is reduced. In addition, the droplets may splash into the heat exchanger 130 due to the auxiliary air flow, and adhere to the walls of the heat exchange tubes to affect the heat exchange efficiency.
Advantageously, one end of the baffle 114 is connected to the inner wall of the condensation duct 110 and is located above the auxiliary air inlet 113, and the other end of the baffle 114 extends downward and is inclined toward a direction away from the auxiliary air inlet 113. The baffle 114 thus provided can better function as a stopper for condensation of liquid droplets. Of course, in other embodiments of the present invention, the baffle 114 may be configured as a plate or other shape parallel to the axis of the auxiliary air inlet 113.
It should be additionally noted here that the baffle 114 serves to prevent the condensed droplets from splashing, and thus the shape and size of the baffle 114 are not particularly limited, that is, a designer may design the size and shape of the baffle 114 according to actual needs.
In some embodiments, as shown in fig. 2, a heating air duct 120 is further defined in the body 100, the heating air duct 120 having a second air inlet 121 and a second air outlet 122, the second air inlet 121 being in communication with the outside of the washing chamber 20, the second air inlet 121 being in communication with the washing chamber 20. It will be appreciated that the air in the heating tunnel 120 is able to dry the dishes in the washing chamber 20 after entering the washing chamber 20, thereby improving the user satisfaction.
It should be noted that the second air inlet 121 may be communicated with the first air outlet 112 of the condensation air duct 110, that is, the condensed air may enter the washing chamber 20 through the heating air duct 120 to dry the dishes, so that the working efficiency of the dishwasher 1 is improved. Of course, in other embodiments of the present invention, the second air inlet 121 is not in communication with the condensing duct 110, but is directly connected to the external environment of the dishwasher 1, that is, the indoor air can enter the washing chamber 20 from the second air inlet 121 to dry the dishes.
In some alternative embodiments, as shown in fig. 2, the heat exchanger 130 includes a first air duct 131 and a second air duct 132 that are isolated from each other and can exchange heat with each other, the first air duct 131 is in communication with the condensation air duct 110, and the second air duct 132 is in communication with the heating air duct 120 and is disposed corresponding to the second air intake 121. It will be appreciated that the air flow in the heating tunnel 120 needs to be heated by the heating device 123 before being introduced into the washing chamber 20 to ensure a good drying effect. Because the heat exchanger 130 is respectively communicated with the condensation air duct 110 and the heating air duct 120, that is, the air flow in the condensation air duct 110 enters the first air duct 131, the air flow in the second air inlet 121 enters the second air duct 132, and because the air flow in the condensation air duct 110 is the air flow with high temperature and high humidity flowing out of the washing cavity 20, the air flow in the second air inlet 121 is the colder external air, the air flow in the heat exchanger 130 entering from the second air inlet 121 can exchange heat with the air flow in the condensation air duct 110, so that the air flow entering from the second air inlet 121 into the heating air duct 120 has a certain temperature, that is, the air flow in the condensation air duct 110 can preheat the air flow entering from the second air inlet 121, so that the heating time of the heating device 123 in the heating air duct 120 can be reduced to a certain extent, and energy is saved.
Of course, in other embodiments of the present invention, the second air duct 132 of the heat exchanger 130 may be directly connected to the external environment of the dishwasher 1, without communicating with the heating air duct 120.
In some embodiments, as shown in fig. 2, a condensing fan 115 is disposed in the condensing duct 110, and the condensing fan 115 is located downstream of the auxiliary air intake 113 in the airflow direction of the condensing duct 110. The condensing fan 115 may accelerate the flow rate of the air flow in the condensing duct 110, thereby improving the efficiency of the dishwasher 1. It should be noted that if the condensing fan 115 is disposed upstream of the auxiliary air intake 113, the air flow that is only subjected to primary condensation by the heat exchanger 130 still contains a relatively large amount of humidity, and long-term operation of the condensing fan 115 in such an environment may reduce the lifetime of the condensing fan 115. The condensing fan 115 is arranged at the downstream of the auxiliary air inlet 113, and the humidity of the air flow of the primary condensation and the secondary condensation of the auxiliary air flow of the heat exchanger 130 is smaller, so that the service life of the condensing fan 115 can be prolonged.
It should be noted that, the condensing fan 115 may be a through-flow fan or an axial-flow fan, and the type and parameters of the condensing fan 115 are not specifically limited herein.
In some alternative embodiments, as shown in fig. 2, the body 100 is provided with a condensed water outlet 116, where the condensed water outlet 116 is in communication with the condensed air duct 110, and the condensed water outlet 116 is located between the condensing fan 115 and the auxiliary air inlet 113 in the airflow direction of the condensed air duct 110. It will be appreciated that the condensed water produced by the primary condensation of the heat exchanger 130 and the secondary condensation of the secondary air intake stream can be discharged from the condensed water discharge port 116 to the designated container, thus avoiding the occurrence of water accumulation in the drying apparatus 10 that affects the operation of the drying apparatus 10. In addition, by disposing the condensed water drain 116 downstream of the condensing fan 115, it is possible to prevent condensed liquid droplets from affecting the normal operation of the condensing fan 115.
In some embodiments, as shown in fig. 2, a plurality of first diversion ribs 117 are disposed in the condensation duct 110 adjacent to the first air inlet 111, and the plurality of first diversion ribs 117 are distributed at intervals along the circumferential direction of the first air inlet 111. Thus, the air flow in the condensation duct 110 can be ensured to flow smoothly. It should be noted that, because the effect of the first flow guiding ribs 117 is only to guide the air flow, the specific shape and number of the first flow guiding ribs 117 are not limited, and a designer can design the shape and number of the first flow guiding ribs 117 according to actual needs to ensure that the first flow guiding ribs 117 have an optimal flow guiding effect.
In some embodiments, a second deflector 125 is disposed within the heating tunnel 120, the second deflector 125 being downstream of the heat exchanger 130 in the direction of airflow of the heating tunnel 120. Thus, the air flow in the heating duct 120 can be ensured to be smooth. It should be noted that, because the second flow guiding ribs 125 only serve as flow guiding air, the specific shape and number of the second flow guiding ribs 125 are not limited, and a designer can design the shape and number of the second flow guiding ribs 125 according to actual needs to ensure that the second flow guiding ribs have an optimal flow guiding effect.
In some embodiments, as shown in fig. 2, a drying fan 124 and a heating device 123 are disposed in the heating tunnel 120, the drying fan 124 is located downstream of the heat exchanger 130 in the airflow direction of the heating tunnel 120, and the heating device 123 is located downstream of the drying fan 124. It will be appreciated that the drying blower 124 can accelerate the air flow in the heating tunnel 120, thereby improving the drying efficiency of the dishwasher 1. When the heat exchanger 130 is respectively connected to the condensing air duct 110 and the heating air duct 120, the air flow entering from the second air inlet 121 in the heat exchanger 130 can exchange heat with the air flow in the condensing air duct 110, so that the air flow entering from the second air inlet 121 into the heating air duct 120 has a certain temperature, and the heating device 123 is arranged at the downstream of the heat exchanger 130.
In some embodiments, as shown in fig. 2, a plurality of separation ribs 140 are provided in the body 100, a part of the condensation duct 110 and the heating duct 120 is separated by the plurality of separation ribs 140, another part of the heating duct 120 is formed by a duct member 150 detachably connected to the body 100, and the heating device 123 is provided in the duct member 150. It will be appreciated that, since the air duct member 150 is provided in the heating air duct 120, and the heating device 123 is provided in the air duct member 150, such a method of providing is due to protection, maintenance and replacement of the heating device 123.
