静音烘干装置

Abstract

本实用新型涉及一种静音烘干装置，包括门板和柜体，柜体包括外壳和内壳，内壳与门板形成用于容置物品的腔体，外壳和内壳之间形成空腔，空腔内设有加热件，外壳的下部设有与外界连通的第一通气口，内壳的下部设有第二通气口，内壳的上部设置有第三通气口，外壳的上部设置有与外界连通的第四通气口；在加热件工作状态下，第一通气口、第二通气口、第三通气口和第四通气口形成烟囱效应。本实用新型得到的一种静音烘干装置，具有以下优点：利用加热件加热产生的温差形成气体流动驱动力，再结合独特的气体通道设计，在不使用风扇的情况下即可实现高温杀菌且排出水分的功能，消除了现有同类产品中的主要噪声来源，有效地减小了工作噪音。

Claims

5. A silent drying device according to claim 4, characterized in that: A first gap is provided between the heating element and the outer wall of the inner shell; a second gap is provided between the heating element and the inner wall of the outer shell.

6. The silent drying device according to claim 4, characterized in that: A support member is provided inside the lower cavity, and the heating element is connected to the support member.

7. The silent drying device according to claim 3, characterized in that: The first and second vents are staggered; the third and fourth vents are arranged opposite each other.

8. The silent drying device according to claim 1, characterized in that: The heating element is located between the side of the outer shell and the side of the inner shell; the first vent is located on the bottom surface of the outer shell, the second vent is located on the side of the inner shell, the third vent is located on the top surface of the inner shell, and the fourth vent is located on the top surface of the outer shell; the partition is arranged obliquely, and the height of the partition gradually increases from the connection point with the outer shell to the connection point with the inner shell; the bottom surface of the outer shell is provided with foot pads.

9. The silent drying device according to claim 1, characterized in that: The heating element is located between the side of the outer shell and the side of the inner shell, and between the bottom surface of the outer shell and the bottom surface of the inner shell; the cross-section of the heating element is L-shaped; the first vent is located on the bottom surface of the outer shell, the second vent is located on the side of the inner shell, the third vent is located on the top surface of the inner shell, and the fourth vent is located on the top surface of the outer shell.

10. The silent drying device according to claim 6, characterized in that: The heating element is located between the side of the outer shell and the side of the inner shell; the first vent is located on the bottom surface of the outer shell, the second vent is located on the side of the inner shell, the third vent is located on the side of the inner shell, and the fourth vent is located on the side of the outer shell; the bottom of the support is connected to the bottom surface of the outer shell, the top of the support is connected to the side of the outer shell, and the heating element is located on the side of the support facing the second vent.
