Abstract

An induction heater and a water dispenser having an induction heater are provided. The induction heater may include a hot water tank assembly formed by coupling edges of a first cover and a second cover to each other and provided with an inner space to heat liquid. The first cover may be configured to have a flat plate shape and to be heated by a working coil. The second cover may include a base configured to face the first cover and separated from the first cover, and a welding portion formed by welding with the first cover and provided on a protruding surface that protrudes from the base toward the first cover.

Claims

1. An induction heater, comprising:

a first cover;

a second cover; and

a hot water tank assembly formed by coupling edges of the first cover and the second cover to each other, and provided with an inner space to heat liquid, the first cover having a flat plate and to be heated by a working coil, wherein the second cover includes;

a base configured to face the first cover and separated from the first cover; and

a welding portion formed by welding with the first cover and formed on a protruding surface that protrudes from the base toward the first cover.

2. The induction heater of claim 1, wherein the second cover include:

a water inlet pipe configured to receive liquid; and

a flow dispersion portion connected to the water inlet pipe and formed to protrude in a direction away from the first cover, wherein a distance between the flow dispersion portion and the first cover may be larger than that between the base and the first cover.

3. The induction heater of claim 1, wherein the second cover include:

a water outlet pipe configured to discharge liquid; and

a flow joining portion connected to the water outlet pipe and formed to protrude in a direction away from the first cover, wherein a distance between the flow joining portion and the first cover may be larger than that between the base and the first cover.

4. The induction heater of claim 1, wherein the second cover include:

a water inlet pipe configured to receive liquid;

a water outlet pipe configured to discharge liquid;

a flow dispersion portion connected to the water inlet pipe and formed to protrude in a direction away from the first cover, wherein a distance between the flow dispersion portion and the first cover may be larger than that between the base and the first cover; and

a flow joining portion connected to the water outlet pipe and formed to protrude in a direction away from the first cover, wherein a distance between the flow joining portion and the first cover may be larger than that between the base and the first cover.

5. The induction heater of claim 1, wherein the second cover includes a protrusion portion protruding from the base toward the first cover.
