Description

Technical Field [0001] The present invention relates to a cable cover for a top cover,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable sealing structure of a top cover, and more particularly, to a cable sealing structure of a top cover that improves the sealing performance of a wire cable leading into a top cover of an electric pressure cooker.

BACKGROUND ART In general, an electric pressure cooker is a kitchen cooking appliance that heats an airtight container (inner tube or inner pot) containing cooked food by electric heating means.

Such an electric pressure cooker can be largely divided into a main body, a lid (assembly) which is inserted into the main body, an inner passage containing cooked food (cooked food), and a lid (assembly)

Inside the main body, a control unit for controlling a series of operations such as cooking, keeping warm, and discharging steam, a display unit for displaying an operating state, and an operation unit for the user to select a cooking mode or a keep-warm mode.

A heating means such as an induction heater (IH) for heating the inner tube is provided in the body. The lid has a heat radiating plate which is placed on an upper portion of the inner cylinder at the time of cooking to serve as a lid of an inner cylinder which hermetically closes the inner cylinder.

In the electric pressure cooker, the inner cylinder containing the food is heated while being sealed by the heat sink, so the inner cylinder always maintains the high temperature and high pressure state during cooking. In addition, it is very important to improve the sealing performance of the inner tube to improve the cooking function and the warming function.

Recently, the conventional top cover (rice cooker lid) of the conventional electric pressure cooker is equipped with a PCB inside to display various information on an external display window (e.g., LCD), and a communication cable The FF cable) is drawn into the top cover.

As a result, there has been a problem such that steam or foreign matter enters the cable mounting portion in the top cover when the communication cable is drawn in, thereby damaging internal electronic components.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, an LCD 20 for displaying a cooking state, a temperature, and the like is formed on the outer side of the top cover body 10, and a PCB 20 The cables 30a and 30b are connected to the PCB 30 through the cable sealing structures 50a and 50b so that the cables 40a and 40b are connected to the main body Respectively.

On the other hand, inside the top cover body 10, a shielding wall 12 is formed along the periphery. This shielding wall 12 blocks steam from entering the steam outlet 11 formed in the top cover body 10.

The cables 40a and 40b pass through a part of the shielding wall 12 and the cables 40a and 40b are connected to each other through the cable sealing structures 50a and 50b in order to block steam from entering the periphery of the cables 40a and 40b. 40a, and 40b are induced to enable electrical connection.

3 and 4, it can be seen that the fixing portion 52 of the cable sealing structure 50 and the sealing rubber portion 51 are located in a part of the shielding wall 12. [

The cable sealing structure 50 is configured so that the upper surface of the sealing portion 51 and the shielding wall 12 formed on the upper surface of the fixing portion 52 fixed to the inside of the top cover body 10 are in contact with each other.

Referring to FIG. 5, the cable sealing structure 50 of the present invention is installed in a state where the sealing rubber portion 51 made of silicone or rubber is seated on the fixing portion 52 made of synthetic resin. The sealing rubber portion 51 is a member through which the cable 40 penetrates and seals the periphery of the cable 40. The fixing portion 52 is a member for fixing the fixing portion 52 to the inner surface of the top cover body 10. [

6 and 7, the sealing rubber portion 51 is formed with a sealing region 56 passing through the center thereof. The sealing region 56 is formed to be narrower than the thickness of the cable 40, and is formed to be wider than the width of the cable 40. The upper and lower surfaces of the closed area 56 are brought into close contact with the upper and lower surfaces of the cable 40 and the closed areas 56 outside the width of the cable 40 are in contact with each other Thereby sealing the periphery of the cable 40. The inlet portion 55 and the outlet portion 57 having a relatively wide width are formed at the inlet and the outlet of the hermetically sealed region 56.

8 and 9, the fixing portion 52 is formed with a support portion 58 having a groove formed therein for inserting the mounting end 54 of the sealing rubber portion 51, and extends from the support portion 58 And a mounting portion 53 formed with a mounting hole h are integrally formed.

At this time, a bolt (BT) is inserted into the mounting hole (h) and can be fixed to the inner surface of the top cover body (10).

10 and 11, a cable enclosing structure 50 is installed in a part of the shielding wall 12 of the top cover body 10 to allow the cable 40 to be inserted. At this time, in the cable sealing structure 50, the cable 40 is passed through the sealing region 56 of the sealing rubber portion 51, and the cable 40 is closely attached to the periphery of the cable 40, .

On the other hand, the cable sealing structure 50 is mounted inside the top cover body 10 with the bolts BT fastened to the mounting portions 53 of the fixing portions 52.

The cable sealing structure 50 mounted in this way has a structure in which the sealing rubber portion 51 is brought into close contact with the shielding wall 12 of the top cover so that external steam is drawn inwardly And the sealing rubber portion 51 for sealing the cable 40 can be easily mounted inside the top cover through the fixing portion 52. [

According to the present invention configured as described above, it is possible to prevent steam or foreign matter from flowing into the vicinity of the cable 40 through the sealing rubber portion 51 through which the cable 40 penetrates, and is mounted with the bolts BT inside the top cover The sealing rubber portion can be easily installed through the fixing portion 52, so that the manufacturing performance can be improved as well.

While the present invention has been particularly shown and described with reference to the particular embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
