Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 2, the present embodiment provides a hot air device 1 of a dishwasher 100, including: a housing 11, a fan assembly 14, and a heating assembly 15.

Wherein, the housing 11 can form an air duct 12, providing a place for air to flow; the housing 11 also serves to form an insulating passageway 13, the insulating passageway 13 being provided around the duct 12 to provide a location for the flow of cryogenic gas. The fan assembly 14 is used to drive the airflow from the inlet to the outlet of the air chute 12, and the fan assembly 14 is also used to drive the airflow from the inlet to the outlet of the insulated tunnel 13. The heating assembly 15 is disposed in the air duct 12, and the heating assembly 15 is configured to heat the air flow in the air duct 12, so that the air flow is changed into a high-temperature air flow after passing through the heating assembly 15.

Specifically, the housing 11 may have a wind tunnel 12 formed therein, and the wind tunnel 12 may have a first inlet 121 and a first outlet 122, and the first inlet 121 and the first outlet 122 may be used to form an airflow passage. The housing 11 may further have an insulation passage 13 formed therein, the insulation passage 13 may be disposed around the outside of the wind tunnel 12, and the insulation passage 13 may have a second inlet 131 and a second outlet 132. The heating assembly 15 may be disposed in the wind tunnel 12 and the fan assembly 14 may be configured to drive airflow from the first inlet 121 to the first outlet 122, and the fan assembly 14 may be configured to drive airflow from the second inlet 131 to the second outlet 132. That is, two air flow passages are formed inside the housing 11, wherein the heat insulation passage 13 is disposed at the outer periphery of the air duct 12 to prevent the housing 11 from having an excessively high temperature. The fan assembly 14 can simultaneously deliver airflow to the air duct 12 and the heat insulation channel 13, the airflow enters from the first inlet 121 and is heated by the heating assembly 15 in the air duct 12 to become high-temperature air, and the airflow enters the heat insulation channel 13 from the second inlet 131 and is directly discharged from the second outlet 132 along the airflow channel.

After the fan assembly 14 is started, a part of the airflow generated by the fan assembly 14 enters the air duct 12 from the first inlet 121, flows through the heating assembly 15 in the air duct 12, is heated by the heating assembly 15 to become high-temperature airflow, and is discharged from the first outlet 122; another portion of the airflow enters the insulating passageway 13 from the second inlet 131 and exits through the second outlet 132. Since the insulating passageway 13 is provided around the wind tunnel 12, the air flow in the insulating passageway 13 cannot be directly heated by the heating assembly 15 disposed in the wind tunnel 12, and thus the insulating passageway 13 delivers the lower temperature air flow. The low-temperature gas can form protection outside the air duct 12, the heat of the air flow in the air duct 12 cannot be directly dissipated to the outside of the shell 11, the heat dissipation in the air duct 12 is reduced, and the high temperature generated by the heating component 15 can be blocked, so that the service life and the safety of the hot air device 1 are improved.

According to the utility model discloses hot-blast apparatus 1 of dish washer 100 has set up thermal-insulated passageway 13 on the lateral wall of wind channel 12, can insulate against heat through thermal-insulated passageway 13 to the air current in wind channel 12, reduces or avoids the heat in wind channel 12 directly to scatter and disappear outside shell 11 to can improve hot-blast apparatus's 1 energy utilization effectively.

Specifically, a part of the airflow generated by the fan assembly 14 enters the air duct 12, and because the heating assembly is disposed in the air duct 12, the airflow entering the air duct 12 will flow to the first outlet after exchanging heat with the heating assembly, that is, the airflow passes through the heating assembly 15 in the air duct 12, and the airflow is heated by the heating assembly 15 to become a high-temperature airflow, and is discharged from the first outlet 122; another part of the airflow enters the insulating passage 13 from the second inlet 131, and since the insulating passage 13 is disposed around the outside of the wind tunnel 12 and the airflow in the insulating passage 13 is isolated from the wind tunnel 12, the heating element cannot directly heat the airflow in the insulating passage 13, in other words, the heating element is isolated from the insulating passage 13. The air flow in the insulating passageway 13 cannot be directly heated by the heating assembly 15 disposed in the air chute 12. Thus, a lower temperature gas stream is conveyed through the insulated tunnel 13. The heat in the air duct is difficult to directly exchange heat with the external environment of the hot air device, so that the heat exchange efficiency is effectively reduced, the energy utilization rate is improved, and meanwhile, the heat exchange rate between the air flow in the heat insulation channel 13 and the external environment can be reduced due to the fact that the temperature of the air flow in the heat insulation channel 13 is low.

In addition, the heat insulation air duct 13 can prevent the heat in the air duct 12 from being directly radiated outside the shell 11, so that the temperature of the outer surface of the shell 11 can be reduced, and the influence on other components outside the shell 11 is reduced. Moreover, because the temperature of the airflow in the heat-insulating air duct 13 is relatively low, most of the heat in the air duct 12 is absorbed by the airflow in the heat-insulating air duct 13 in the process of outward dissipation, so that the heat dissipation can be reduced, and the utilization rate of energy is improved.

Alternatively, the fan assembly 14 may be configured to be connected to both the first inlet 121 and the second inlet 131, with the fan assembly 14 delivering airflow to both the wind tunnel 12 and the insulating passageway 13. In addition, the fan assembly 14 may also include a plurality of fans, one fan is connected to the air duct 12 for driving the air flow in the air duct 12, and one fan is connected to the heat insulation passage 13 for driving the air flow in the heat insulation passage 13. In addition, a fan provided separately for the heat insulation passage 13 may be a fan that introduces cold air.

In addition, the heat insulation passage 13 may be provided on both sides of the air duct 12, or the heat insulation passage 13 may be provided on one side wall of the air duct 12.

Alternatively, the second inlet 131 of the insulating passageway 13 communicates with the wind tunnel 12, and the second inlet may be located downstream of the first inlet, so that the structure of the hot wind device may be simplified by only connecting the fan assembly to the first inlet. Therefore, the fan assembly can be communicated with the first inlet, thereby simplifying the structure.

In addition, when the air flow reaches the second inlet 131, a part of the air flow enters the heat insulation passage 13, and a part of the air flow enters the air duct 12. The second inlet 131 is located upstream of the heating assembly 15 in the airflow direction in the air duct 12, that is, after the airflow enters the air duct 12, the airflow enters the insulated air duct 13 through the second inlet 131 before passing through the heating assembly 15. Since the air flow is changed into a high temperature air flow after passing through the heating assembly 15, the second inlet 131 is disposed at the upstream of the heating assembly 15 to ensure that the fluid entering the heat insulation passage 13 is a low temperature air flow.

In addition, it may be arranged that the second inlet 131 is opposite to the heating assembly 15 in the airflow direction in the air duct 12, that is, after the airflow enters the air duct 12, the airflow enters the heat insulation air duct 13 through the second inlet 131 when passing through the heating assembly 15. Since the air flow is changed into a high temperature air flow after passing through the heating assembly 15, the second inlet 131 is disposed opposite to the heating assembly 15, and the air flow entering the heat insulation air duct 13 is not heated by the whole heating assembly 15, so as to ensure that the fluid entering the heat insulation air duct 13 is a low temperature air flow relative to the air flow in the air duct 12.

Alternatively, the second inlet 131 of the insulating passageway 13 is in direct communication with the first inlet 121 of the wind tunnel 12. The air flow is convenient to enter the air flow channel respectively, the structure is simple, and the production and the installation are easy. When the same fan is used to drive the air flow, the fan assembly 14 can simultaneously feed the air flow into the air duct 12 and the heat insulation channel 13 through the first inlet 121 and the second inlet 131, thereby improving the heat insulation effect and simplifying the structure of the hot air device.

The utility model discloses hot-blast device 1 can utilize the air current that same fan produced, when reaching to make the air current from first export 122 and second export 132 discharge, has produced the effect of high temperature air current and low temperature air current respectively, plays energy-conserving effect. Of course, the second inlet 131 and the air duct 12 may be provided in a non-communicating manner, or the fan assembly 14 may separately supply air, etc.

A guide structure 17 may be provided on a side wall of the wind tunnel 12, the guide structure 17 being configured to guide the airflow within the wind tunnel 12 to the second inlet 131 of the heat insulation passage 13 located at the upper side. The structure of the hot air device can be further simplified, and after the structure is simplified, the stable air flow can still be ensured to be led to the heat insulation channel 13. The performance of the hot air device is improved.

In addition, when the insulation passage 13 is provided at the side of the housing 11 having the wire through hole 16, the second inlet 131 of the insulation passage 13 may be provided downstream of the wire through hole 16, thereby providing a relief for the wire through hole 16. At this time, the second inlet 131 is not aligned with the fan assembly 14, most of the air flow passes through the heating assembly 15 to become high temperature air flow, and less air flow passes through the gap between the heating assembly 15 and the wire passing hole 16, so that the guide structure 17 may be provided upstream adjacent to the second inlet 131 to guide the air flow not passing through the heating assembly 15 to the second inlet 131 to enter the heat insulation passage 13. The guiding structure 17 may be disposed upstream of the second inlet 131, and may be a triangular protrusion with a certain inclination angle, or may be a section of the guiding structure 17 extending from the second inlet 131, for example, an end of the second inlet 131 close to the heating assembly 15 is disposed in a flaring shape, so as to facilitate the air flow entering the second inlet 131.

Wherein, the utility model provides a guide structure can have different forms, for example in the utility model discloses a specific example, on the lateral wall in wind channel can be located to the second import, guide structure can be constructed into the aviation baffle shape, guide structure can link to each other with the inboard edge of second import, and guide structure can be towards the wind channel in and towards the slope shape that first import extends to at the in-process that the air current passes through guide structure, guide structure can be smoothly with the air current towards thermal-insulated passageway in the guide, improve the stability to the air supply in the thermal-insulated passageway.

Additionally, in another example of the present invention, the second inlet is disposed on a sidewall of the air duct, and the second inlet is opposite to the heating assembly, a gap is provided between the heating assembly and the sidewall of the air duct, the guiding structure is configured in a shape of a wind guiding bump, the wind guiding bump is disposed on the sidewall of the heating assembly, and the wind guiding bump is opposite to the second inlet, and the wind guiding bump has a guiding inclined plane adapted to guide the air flow toward the second inlet.

When the insulation passage 13 is provided at the side of the housing 11 where the wire through hole 16 is provided, the air flow enters from the first inlet 121, a part of the air flow passes through the heating assembly 15, and a part of the air flow passes through the gap between the heating assembly 15 and the wire through hole 16. The second inlet 131 of the insulating passage 13 is located downstream of the wire passing hole 16 in the airflow direction in the air duct 12, and the second inlet 131 of the insulating passage 13 is communicated with the air duct 12, so that the airflow passing between the heating assembly 15 and the wire passing hole 16 can enter the insulating passage 13 when the airflow reaches the second inlet 131. The problem of crossing the hindrance of line hole 16 to thermal-insulated passageway 13 air inlet is solved, and then reduced heating element 15 during operation to the high temperature of shell 11 production, avoided simultaneously because of crossing the fire risk that line hole 16 high temperature produced, improved hot-blast device 1's security.
