Embodiment 1

[0030] This embodiment provides a washing machine. The washing machine mentioned in this embodiment may be a drum washing machine or a pulsator washing machine. This embodiment takes a drum washing machine as an example.

[0031] Such as Figure 1 to Figure 4 As shown, the washing machine includes an outer cylinder 1 and a heater 2 connected to the outer cylinder 1. One end of the heater 2 is placed between the outer cylinder 1 and the inner cylinder of the washing machine and connected to the heating of the outer cylinder 1. The heater body 21 is connected to the heater body 21 placed on the outer end of the outer cylinder 1 and used for heating the heating substrate 22, and a controller electrically connected to the heating substrate 22; the heater body 21 Made of thermally conductive material.

[0032] The heater 2 described in this embodiment cancels the installation bracket, and adopts the heater body 21 to pass through the outer cylinder 1, so that one end of the heater...

Embodiment 2

[0047] The difference between the washing machine of this embodiment and the washing machine described in Embodiment 1 is that the structure of the heating base 22 is different, such as Figure 5 As shown, the heating base 22 in this embodiment includes an inner insulating medium layer 221, a resistance heating layer 222 and an outer insulating medium layer 223 arranged in sequence along the direction from the inside of the outer cylinder 1 to the outside of the outer cylinder 1. ; The end of the heater body 21 placed outside the outer cylinder 1 is connected to the inner insulating medium layer 221 ; the inner insulating medium layer 221 is made of thermally conductive material.

[0048] The controller is used to control the heating base 22 to work, and heat is generated through the resistance heating layer 222. The heat generated by the resistance heating layer 222 is transferred to the heater body 21 through the inner insulating medium layer 221, and then transferred to the ...

Abstract

The invention relates to the field of washing machines, and discloses a washing machine. The washing machine comprises an outer tub, a heater connected to the outer tub and a heating base connected tothe end, outside the outer tub, of a heater body and used for heating; one end of the heater is arranged between the outer tub and an inner tub of the washing machine and connected to the heater bodyof the outer tub, the heating base is electrically connected to a controller of the washing machine, and the heater body is made of heat conducting materials. According to the heater, only one end ofthe heater body is arranged inside the outer tub, an installing support is canceled, the structure that the heater is arranged inside the outer tub is omitted, and therefore the foreign matter woundaround the interior of the outer tub of the heater body is reduced to a certain degree; the heating base for heating is arranged outside the outer tub, the heater body only has the effect of heat transfer, even when wire chips are wound around the heater body, only the heat transfer efficiency is affected, and a dry-burning problem is not caused.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine. Background technique [0002] In current washing machines, such as pulsator washing machines or drum washing machines, in order to enhance the washing effect, a heater is arranged on the inner bottom wall of the outer tub to heat the water in the outer tub, and the water in the entire washing tub is gradually heated by the rotation of the inner tub. [0003] The existing heater includes a mounting bracket fixed on the inner bottom wall of the outer cylinder, and a heating pipe connected to the mounting bracket. Since the heating tube and the mounting bracket are easily entangled with foreign matter such as wire scraps and paper pieces, as time goes by, the foreign matter entangled on the surface of the heating tube and the mounting bracket will gradually increase; and because the heater is located between the outer cylinder and the inner cylinder , The wire scr...
