Description

Technical Field

[0001] The utility model belongs to the technical field of heat source installation, and particularly relates to a bottom heat source assembly structure. Background Art

[0002] Cooking utensils such as electric slow cookers generally install a heat source at the bottom, and when heating, the heat is conducted to the inner pot to cook food. The existing heat source assembly structure simply installs a heating plate at the bottom of the cover. During the cooking process, a large amount of water often remains on the outer surface of the inner pot. The long-term contact between the water and the heating plate easily causes the heating plate to be damaged by moisture, affecting the short service life of the electric slow cooker. In addition, the exposed heat source is easily damaged due to misoperations such as user collisions. Summary of the Utility Model

[0003] (1) Purpose of the Utility Model

[0004] In order to overcome the above deficiencies, the purpose of the utility model is to provide a bottom heat source assembly structure to solve the technical problems that the existing heat source is easily damaged by moisture due to long-term direct contact with water, and the exposed heat source is easily damaged due to misoperations such as user collisions.

[0005] (2) Technical Solution

[0006] To achieve the above purpose, the technical solution provided by this application is as follows:

[0007] A bottom heat source assembly structure includes: a heat preservation cover, a heat source arranged at the bottom of the heat preservation cover, a water-blocking convex rib formed by the heat preservation cover protruding upward at a position surrounding the heat source, and a heat conduction cover covering above the heat source and abutting against the heat source. Among them, a drainage hole penetrating the heat preservation cover is opened at the bottom of the heat preservation cover outside the water-blocking convex rib;

[0008] In this application, by covering a heat conduction cover above the heat source, the heat source conducts heat to the inner pot through the heat conduction cover to heat food. The heat conduction cover can block the accumulated water on the surface of the inner pot from flowing onto the heat source. In addition, by setting a water-blocking convex rib and opening a drainage hole at the bottom of the heat preservation cover, it can block the accumulated water from flowing onto the heat source through the gap between the heat conduction cover and the bottom of the heat preservation cover. When there is more accumulated water, it can also be discharged outward through the drainage hole to ensure the dryness of the heat source, extend the service life of the rice cooker, and it is not easy for users to collide with the heat source to cause damage.

[0009] In some embodiments, the drainage holes are multiple and are arranged at intervals around the water-blocking convex rib;

[0010] By opening multiple circumferentially arranged drainage holes, the accumulated water can be discharged in all directions from multiple directions to ensure the dryness of the heat source.

[0011] In some embodiments, the heat source is detachably connected to the bottom of the heat preservation cover;

[0012] After the heat source is damaged, it can be directly disassembled and replaced, which is convenient for maintenance.

[0013] In some embodiments, it further includes: a mounting base for mounting the heat source, and first mounting holes for fixing the mounting base to the bottom of the heat insulation cover are provided at corresponding positions on the bottom of the heat insulation cover and the mounting base.

[0014] In some embodiments, second mounting holes for fixing the heat conduction cover to the heat insulation cover are respectively provided at corresponding positions on the bottom of the heat insulation cover and the heat conduction cover. Description of the Drawings

[0020] A bottom heat source 3 assembly structure provided by the present utility model includes: a heat insulation cover 1, a heat source 3 provided at the bottom of the heat insulation cover 1, a water retaining rib 201 formed by the heat insulation cover 1 protruding upward at a position surrounding the heat source 3, and a heat conduction cover 2 covering the heat source 3 and abutting against the heat source 3, wherein a drainage hole 202 penetrating the heat insulation cover 1 is provided at the bottom of the heat insulation cover 1 outside the water retaining rib 201.

[0021] Specifically, the heat source 3 can be a related heat source 3 such as PTC, heating film, heating tube, heating plate, etc.

[0022] Specifically, the heat source 3 is mounted on a mounting base, and first mounting holes are respectively provided at corresponding positions on the bottom of the mounting base and the bottom of the heat insulation cover 1, and screws can be inserted to lock the mounting base to the bottom of the heat insulation cover 1.
