Problems solved by technology

The scale on the heating pipe can be removed by installing a cleaning device on the outer barrel, but to install the cleaning device, on the one hand, another opening needs to be opened on the outer barrel, which greatly reduces the strength of the outer barrel. In addition, the cleaning device is installed on the lower part of the outer barrel , the reduction of the strength of the outer barrel has a greater impact on the life and installability of the outer barrel. On the other hand, the cleaning device is arranged at the lower part of the outer barrel. Install the cleaning device separately at the lower part of the tank, and also consider wiring, waterproof, leakage prevention and other issues

Embodiment 1

[0037] like Figure 1-2 As shown, a heater includes a heater body 100, an ultrasonic generator 101 is provided on the heater body 100, and the ultrasonic generator 101 is used to remove scale deposited on the heater body 100 when heating water . The ultrasonic generating device 101 is integrated on the heater body 100 to form an integral part. On the one hand, the number of openings on the outer cylinder or other equipment is reduced, and the impact on the strength of the outer cylinder or other equipment is reduced. On the other hand, disassembly The inspection of the heater body 100 and the ultrasonic generator 101 can be realized at one time, and the installation space of the heater body 100 and the ultrasonic generator 101 is greatly reduced.

[0038] In a further solution, the heater body 100 includes a mounting part 103 and a heating part 102 disposed on the mounting part 103 , and the ultrasonic generating device 101 is disposed on the mounting part 103 and / or the heat...

Embodiment 2

[0057] A washing machine with the heater described in Embodiment 1 includes an outer tub, and the heater body 100 is arranged on the outer tub to heat the washing water in the outer tub.

[0058] The washing machine is explained as an example where the washing machine is a drum washing machine.

[0059] The washing machine includes an outer cylinder and an inner cylinder, and the heater is arranged on the lower part of the bottom wall of the outer cylinder to prevent dry burning.

[0060] The heater includes a heating tube 105 and a tube plate 104, and the heating tube 105 is a U-shaped heating tube. The tube plate 104 is elongated and has a major axis. The tube plate 104 is provided with two mounting ports for installing the heating tube 105. The center of the mounting port is longer than the major axis, and the two ends of the heating tube 105 pass through the two openings respectively. And be connected with heating tube 105 connection terminal 108.

[0061] A mounting hol...

Embodiment 3

[0067] This embodiment is the control method of the washing machine in the second embodiment. During the process of heating the washing water by the heater, the washing machine controls the ultrasonic generator 101 to turn on to clean the scale deposited on the heater body 100 .

[0068] In a further solution, the washing machine also includes a temperature detection device for detecting the temperature of the washing water. During the process of heating the washing water by the heater, the washing machine controls the ultrasonic generator 101 to turn on according to the temperature of the washing water detected by the temperature detection device.

[0069] In a further solution, the washing machine calculates the temperature change rate of the washing water according to the temperature of the washing water detected by the temperature detection device, and controls the ultrasonic generator 101 to turn on according to the temperature change rate of the washing water.

Abstract

The invention belongs to the field of washing machines, and particularly relates to a heater, a washing machine provided with the heater and a control method thereof. The heater comprises a heater body, the heater body is provided with an ultrasonic generating device, and the ultrasonic generating device is used for removing scale deposited on the heater body when water is heated. The heater has the advantages that the ultrasonic generating device is integrated on the heater body to form an integral piece, on the one hand, the number of openings formed in an outer cylinder or other equipment is reduced, the influence on the strength of the outer cylinder or other equipment is reduced, on the other hand, the inspection of the heater body and the ultrasonic generating device can be achievedby disassembling once, and the installation space of the heater body and ultrasonic generating device is greatly reduced.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a heater, a washing machine equipped with the heater and a control method. Background technique [0002] The washing machine is equipped with a heater to heat the washing water. During the washing process, the washing water is heated to a certain temperature by the heater, which can not only speed up the washing speed, but also improve the washing effect. However, there are often many ions in the washing water, and the heater After heating the washing water for a period of time, the heating tube of the heater is often covered with scale, which not only affects the heating performance, but also increases power consumption, seriously affecting the performance of the washing machine. In addition, after the scale on the heating pipe falls off in pieces, it will block the drainage pump, resulting in poor drainage and even damage the drainage pump. [0003] Because the heat...
