Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drying device and a drying water tank. Background Technology

[0002] A sink is an essential piece of equipment in the kitchen. After use, residual water is often left on the bottom and sides of the sink. This residual water not only easily breeds bacteria and mold, but can also lead to water stains and limescale formation, affecting the hygiene and appearance of the kitchen.

[0003] Existing technologies provide water tanks with drying functions to prevent the growth of bacteria and mold. One drying method involves supplying hot air to the bottom of the tank. Typically, a duct for hot airflow is installed at the bottom of the tank, with a fan inside to drive the hot airflow and dry the water. However, existing ducts are often winding and circuitous, causing the airflow to change direction multiple times to prolong its path and increase the contact time between the airflow and the water. However, these winding ducts can easily create eddies, leading to localized overheating and uneven heating of the tank, thus affecting the drying effect and quality. Utility Model Content

[0004] The purpose of this invention is to provide a drying device and a drying tank to solve the technical problem of uneven drying in the existing water tank.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A drying apparatus, comprising:

[0007] The drying shell includes a first base plate and a first side plate. The first side plate is arranged circumferentially around the first base plate to form a heating cavity with the first base plate. A drying air duct is provided in the heating cavity. The drying air duct has an air inlet, a first region, a second region and an air outlet arranged sequentially. The first region is configured to guide the airflow entering the air inlet to maintain a straight flow. The airflow in the first region is deflected and enters the second region. The projected area of ​​the first region on the first base plate is larger than the projected area of ​​the second region on the first base plate.

[0008] A heating air supply assembly is located outside the drying air duct to supply hot air to the air inlet.

[0009] Preferably, the flow area of ​​at least a portion of the first region gradually increases along the flow direction of the airflow; and / or, the flow area of ​​at least a portion of the second region gradually decreases along the flow direction of the airflow.

[0010] Preferably, the drying air duct includes multiple air paths, and the airflow inlet includes multiple airflow entrances, with one airflow entrance provided for each air path or at least two air paths sharing one airflow entrance.

[0011] Preferably, the drying shell further includes multiple guide ribs, which protrude from the first bottom plate and are located inside the heating cavity. The multiple guide ribs and the first side plate form multiple air passages.

[0012] Preferably, the heating chamber is further provided with a heating air duct, which has an air inlet and an air outlet. The heating air supply component is disposed in the heating air duct, the air inlet is connected to the outside, and the air outlet is selectively connected to the airflow inlet.

[0013] Preferably, the heating and air supply assembly includes a fan and a heating element, the heating element being disposed downstream of the fan, and the airflow outlet being connected to the heating duct and located upstream of the fan.

[0014] Preferably, the device also includes an air guide structure, which is disposed on the side of the drying shell. An air inlet channel is formed inside the air guide structure, and the air inlet is connected to the outside through the air inlet channel. At least a portion of the air inlet channel allows air to enter from top to bottom, and at least a portion of the heating air duct extends in a tortuous manner.

[0015] Preferably, the bottom of the air inlet channel is lower than the air inlet.

[0016] Preferably, the ratio of the projected area of ​​the first region on the first base plate to the projected area of ​​the heating cavity on the first base plate is greater than or equal to 60%.

[0017] A drying tank includes a tank body and a drying device as described above. The tank body includes a bottom plate and a side plate, and the heating chamber is located at the bottom of the bottom plate.

[0018] The beneficial effects of this utility model are:

[0019] The drying device proposed in this utility model has a heating air supply component located outside the drying air duct to supply hot air to the air inlet. The hot air flows sequentially along the drying air duct through the air inlet, the first region, the second region, and the air outlet. The first region is configured to guide the airflow entering through the air inlet to maintain a straight flow, resulting in low air resistance, high flow velocity, and reduced eddies, thus achieving uniform airflow distribution and uniform heating. The airflow in the first region is deflected before entering the second region. Since the projected area of ​​the first region on the first base plate is larger than that of the second region on the first base plate, the first region is larger, thereby achieving uniform heating over a large area.

[0020] The drying tank proposed in this utility model uses the above-mentioned drying device. The heating chamber is located at the bottom of the tank bottom plate. Through the distribution of the airflow inlet, first area, second area and airflow outlet in the drying air duct, the first area guides the airflow entering the airflow inlet to keep it flowing in a straight line. The airflow resistance is low, the flow velocity is high and the eddies are reduced, so that the airflow is evenly distributed. This enables large-area uniform heating of the tank bottom plate, so that the tank body is heated evenly. Attached Figure Description

[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] See Figures 1 to 8 This embodiment provides a drying device, including a drying shell 10 and a heating air supply assembly 20. The drying shell 10 includes a first bottom plate 11 and a first side plate 12. The first side plate 12 is arranged circumferentially around the first bottom plate 11 to form a heating cavity 101. A drying air duct 102 is provided inside the heating cavity 101. The drying air duct 102 has an air inlet 1021, a first region 1022, a second region 1023 and an air outlet 1024 arranged sequentially. The first region 1022 is configured to guide the airflow entering the air inlet 1021 to maintain a straight flow. The airflow in the first region 1022 is deflected and enters the second region 1023. The projected area of ​​the first region 1022 on the first bottom plate 11 is larger than the projected area of ​​the second region 1023 on the first bottom plate 11. The heating air supply assembly 20 is located outside the drying air duct 102 to supply hot airflow to the air inlet 1021.

[0044] The heating air supply assembly 20 is located outside the drying air duct 102 to supply hot air to the air inlet 1021. The hot air flows sequentially along the drying air duct 102 through the air inlet 1021, the first region 1022, the second region 1023, and the air outlet 1024. The first region 1022 is configured to guide the airflow entering from the air inlet 1021 to maintain a straight flow, resulting in low air resistance, high flow velocity, and reduced eddies, thus achieving uniform airflow distribution and uniform heating. The airflow in the first region 1022 is deflected before entering the second region 1023. Since the projected area of ​​the first region 1022 on the first base plate 11 is larger than the projected area of ​​the second region 1023 on the first base plate 11, the first region 1022 is larger, thereby achieving uniform heating over a large area.

[0045] In some embodiments, the ratio of the projected area of ​​the first region 1022 on the first base plate 11 to the projected area of ​​the heating cavity 101 on the first base plate 11 is greater than or equal to 60%. In some embodiments, the ratio of the projected area of ​​the first region 1022 on the first base plate 11 to the projected area of ​​the heating cavity 101 on the first base plate 11 is greater than or equal to 70%. In some embodiments, the ratio of the projected area of ​​the first region 1022 on the first base plate 11 to the projected area of ​​the heating cavity 101 on the first base plate 11 is equal to 60%, 65%, 70%, 75%, or 80%. The larger the first region 1022, the larger the area of ​​airflow entering from the airflow inlet 1021 will maintain a straight flow, ensuring uniform heating.

[0046] in, Figure 3 , Figure 7 and Figure 8 The middle arrow indicates the direction of airflow. For example... Figure 3As shown by the middle arrow, along the flow direction of the airflow, the flow area of ​​at least part of the first region 1022 gradually increases, which slows down the airflow speed, increases the contact time between the airflow and the workpiece to be dried, and makes the airflow dispersed and improves the heat exchange efficiency.

[0047] A flow guide structure is provided between the first region 1022 and the second region 1023 to guide the airflow in the first region 1022 to deflect, that is, to guide the airflow in the first region 1022 to change direction and enter the second region 1023. The deflection angle can be set according to actual needs. For example, the deflection angle is less than or equal to 30 degrees to reduce vortices.

[0048] Optionally, the second region 1023 is configured to guide the airflow to maintain a straight flow within the second region 1023, thereby reducing eddies and ensuring uniform temperature within the second region 1023, which is beneficial for uniform heating of the workpiece to be dried.

[0049] Along the direction of airflow, the flow area of ​​at least part of the second region 1023 gradually decreases, which slows down the airflow speed, increases the contact time between the airflow and the workpiece to be dried, and makes the airflow dispersed and improves the heat exchange efficiency.

[0050] The drying duct 102 may include one air path or multiple air paths. By setting multiple air paths, uniform heating during drying can be further ensured. In this embodiment, the drying duct 102 includes multiple air paths, and the airflow inlet 1021 includes multiple airflow entrances. One airflow entrance is set for each air path, or at least two air paths share one airflow entrance to ensure sufficient ventilation.

[0051] Specifically, the drying shell 10 also includes multiple guide ribs 13, which protrude from the first bottom plate 11 and are located within the heating chamber 101. The multiple guide ribs 13 and the first side plate 12 form multiple airflow paths. The guide ribs 13 can extend in a straight line or in an arc. At least some of the guide ribs 13 bend and extend between the first region 1022 and the second region 1023 to form a guiding structure, guiding the airflow in the first region 2032 to flow to the second region 2033 after a change in direction. The guide ribs 13 and the first bottom plate 11 can be integrally formed or welded together, facilitating processing and production.

[0052] A heating air duct 103 is also provided inside the heating chamber 101. The heating air duct 103 has an air inlet 1031 and an air outlet 1032. A heating air supply assembly 20 is disposed inside the heating air duct 103. The air inlet 1031 is connected to the outside, and the air outlet 1032 is selectively connected to the airflow inlet 1021. The heating air supply assembly 20 can guide the outside airflow to enter from the air inlet 1031, and after flowing through the heating air supply assembly 20 in the heating air duct 103, it flows from the air outlet 1032 to the airflow inlet 1021 of the drying air duct 102.

[0053] The air outlet 1032 is selectively connected to the air inlet 1021. Optionally, the drying device includes a reversing baffle 30 and a driving member 40. The reversing baffle 30 is rotatably connected to the drying housing 10. The driving member 40 can drive the reversing baffle 30 to rotate between a first position and a second position so that the air inlet 1021 is connected to or disconnected from the air outlet 1032.

[0054] The heating and air supply assembly 20 includes a fan 21 and a heating element 22. The heating element 22 is located downstream of the fan 21, and the air outlet 1024 is connected to the heating duct 103 and located upstream of the fan 21. The airflow in the drying duct 102 flows out from the air outlet 1024 into the heating duct 103, passes through the fan 21 and the heating element 22, exits the heating duct 103, and re-enters the drying duct 102, realizing airflow circulation within the drying duct 102 and ensuring that heat is fully utilized.

[0055] The drying device also includes an air guide structure 50, which is disposed on the side of the drying housing 10. An air inlet channel 501 is formed inside the air guide structure 50, and an air inlet 1031 communicates with the outside through the air inlet channel 501. At least a portion of the air inlet channel 501 allows air to enter from top to bottom, and at least a portion of the heating air duct 103 extends in a tortuous manner. The downward airflow of the air inlet channel 501 allows dust to accumulate within it. The tortuous extension of the heating air duct 103 also allows dust to accumulate within it, preventing dust from entering the downstream area of ​​the heating air duct 103.

[0056] Specifically, the air inlet 1031 of the heating channel is the air outlet of the air inlet channel 501. The air inlet 1031 is located on the first side plate 12. The external airflow flows from top to bottom in the air inlet channel 501 to the air inlet 1031 of the heating air duct 103.

[0057] Optionally, the bottom of the air inlet channel 501 is lower than the air inlet 1031 so that dust is deposited at the bottom of the air inlet channel 501 and dust is prevented from entering the air inlet 1031.

[0058] The air guiding structure 50 can be an integral structure or a split structure. In this embodiment, the air guiding structure 50 includes an air guiding housing 51 and an air supply housing 52, with the air supply housing 52 disposed at the top of the air guiding housing 51. The air inlet port 5011 of the air inlet channel 501 is disposed on the upper outer side of the air supply housing 52. External airflow enters the air inlet channel 501 from the air inlet port 5011 in a horizontal direction and flows downward along the air inlet channel 501 to the air inlet 1031 of the heating air duct 103.

[0059] The heating air duct 103 includes an air inlet section 1033 and an air outlet section 1034. The air inlet section 1033 is located upstream of the fan 21, and the air outlet section 1034 is located downstream of the fan 21. At least one of the air inlet section 1033 and the air outlet section 1034 extends in a tortuous manner in the horizontal direction to facilitate dust deposition. In this embodiment, the air inlet section 1033 extends in a straight line in the horizontal direction, and the air outlet section 1034 extends in a tortuous manner in the horizontal direction. The fan 21 is configured to have an upper air inlet and a side air outlet. Exemplarily, the air outlet direction of the fan 21 is opposite to the airflow direction of the air inlet section 1033, thus forming a tortuous section between the air inlet section 1033 and the air outlet section 1034, which is more conducive to dust deposition in the air inlet section 1033. In other embodiments, the air outlet direction of the fan 21 may be set at an angle to the airflow direction of the air inlet section 1033.

[0060] The heating air supply assembly 20 also includes a baffle plate 23, which is disposed within the heating air duct 103. The air inlet section 1033 is located in the upper region of the baffle plate 23, and the air outlet section 1034 is located in the lower region of the baffle plate 23. The baffle plate 23 is positioned such that the air outlet section 1034 is located below the air inlet section 1033. The heating air duct 103 can guide the airflow along a U-shaped curve, and dust entering the heating air duct 103 can be deposited on the baffle plate 23, preventing dust from entering the fan 21 or downstream of the fan 21.

[0061] At least part of the air inlet 1031 is lower than the baffle 23, so that the airflow deflects as it enters the heating duct 103. Dust can be deposited at the air inlet 1031, and less dust enters the area above the baffle 23. The airflow flows along the area above the baffle 23 to the upper side of the fan 21, and the airflow flows out from the side of the fan 21 to the area below the baffle 23. Specifically, the air inlet 1031 of the heating channel is provided on the first side plate 12, and the baffle 23 is spaced apart from the first side plate 12 so that the airflow from the air inlet 1031 can smoothly enter the heating duct 103.

[0062] The drying device also includes a water guiding structure 60, which is located at the bottom of the drying shell 10. A water guiding channel 61 is formed inside the water guiding structure 60. The water inlet 62 of the water guiding channel 61 is connected to the heating air duct 103. The water inlet 62 is located downstream of the heating element 22 and faces away from the heating element 22. The water outlet 63 of the water guiding channel 61 is connected to the outside. Water in the heating air duct 103 can flow out through the water guiding structure 60 to prevent water accumulation in the heating air duct 103. The water inlet 62 is located downstream of the heating element 22 and faces away from the heating element 22 to prevent airflow in the heating air duct 103 from flowing out through the water guiding channel 61.

[0063] A water-guiding slope is provided inside the heating air duct 103 near the water inlet 62 to guide the water flow to the water inlet 62 and prevent the water from entering the drying air duct 102.

[0064] One end of the water guiding structure 60 is located upstream of the heating element 22 and is sealed to the heating air duct 103 to prevent airflow in the heating air duct 103 from flowing out through the water guiding channel 61. Optionally, a double-layer sealing structure is adopted to improve the sealing effect.

[0065] The drying device provided in this embodiment has a good drying effect and can be applied to existing drying tanks or other equipment that requires drying. This embodiment uses a drying tank as an example. See below. Figure 9 and Figure 10 This embodiment provides a drying tank, including a tank body 100 and the aforementioned drying device. The tank body 100 includes a bottom plate 110 and a side plate 120. See [link to documentation]. Figure 7 and Figure 9 The heating chamber 101 is located at the bottom of the sink base plate 110. A drying air duct 102 is provided inside the heating chamber 101. A heating air supply assembly 20 is located outside the drying air duct 102 to supply hot air to the air inlet 1021. The hot air flows sequentially along the drying air duct 102 through the air inlet 1021, the first region 1022, the second region 1023, and the air outlet 1024. The first region 1022 is configured to guide the airflow entering through the air inlet 1021 in a straight line, resulting in low air resistance, high velocity, and reduced eddies, thus achieving uniform airflow distribution and uniform heating. The airflow in the first region 1022 is deflected before entering the second region 1023. Since the projected area of ​​the first region 1022 on the first base plate 11 is larger than that of the second region 1023 on the first base plate 11, the first region 1022 is larger, thus achieving uniform heating over a large area. Therefore, the above-mentioned drying device can dry the sink body 100, keeping it dry and clean, creating a healthy kitchen.

[0066] The side plate 120 of the sink is arranged circumferentially around the bottom plate 110 of the sink to form a cleaning cavity. In this embodiment, the sink body 100 is cuboid, the bottom plate 110 is rectangular, and the side plate 120 is arranged around the circumferential edge of the bottom plate 110. In other embodiments, the sink body 100 can be cylindrical.

[0067] The first side plate 12 is connected to the side plate 120 of the water tank, specifically by bolting or welding. In other embodiments, the first side plate 12 can also be connected to the bottom plate 110 of the water tank.

[0068] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
