Problems solved by technology

Due to the long-term flow and accumulation of washing water between the inner cylinder and the outer cylinder, a large amount of dirt and bacteria will breed, which will cause secondary pollution to the clothes, which is not conducive to human health. Therefore, a washing machine with a non-porous inner cylinder is proposed.
[0004] Since there is no water between the inner cylinder and the outer cylinder of the non-porous inner drum washing machine, and the conventional heating device is arranged on the outer drum of the washing machine to heat the water between the inner drum and the outer drum of the washing machine, therefore, the non-porous inner drum The back of the drum brings inconvenience to the heating of the washing water. Therefore, how to adjust the water temperature in the non-porous inner drum washing machine has become the direction of research and development by technicians.

Embodiment 1

[0073] Such as figure 1 As shown, in this embodiment, the washing machine includes an inner cylinder 1, which holds washing water independently when washing clothes, avoiding the accumulation of dirt outside the inner cylinder 1 and the problems of dirt accumulation and bacterial growth caused by overflowing washing water; The temperature module is used to control the water temperature in the inner cylinder 1; the temperature measurement module includes a temperature measurement device 7 and a control device (not shown in the figure), and the temperature measurement device 7 and the control Wireless communication connection between devices. Data transmission is carried out in the form of wireless communication, which avoids setting a large number of control cables between the inner cylinder 1 and the outer cylinder 2, which will affect the rotation of the inner cylinder 1, and at the same time improves the intelligence level of the washing machine, providing a new home for the...

Embodiment 2

[0104] The main difference between this implementation and the first embodiment is that the installation positions of the temperature measuring devices are different.

[0105] Such as image 3 As shown, in this embodiment, the inner cylinder 1 includes an inner cylinder mouth and an inner cylinder bottom 13 arranged oppositely, an inner cylinder door 11 that can be opened and closed is arranged on the inner cylinder mouth, and the inner cylinder mouth and the inner cylinder bottom 13 pass through The side walls of the inner tube are connected. In this embodiment, the temperature measuring element 71 is arranged on the side wall of the inner tube. In order to prevent the clothes from damaging the temperature measuring element 71, an inner tube A protective cover 75 protruding inside, a cavity is formed between the protective cover 75 and the side wall of the inner cylinder, the temperature measuring element 71 is arranged in the cavity, and the protective cover 75 is provided w...

Embodiment 3

[0111] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that: the water measuring device 6 adopts a liquid level detection device, and the liquid level detection device uses wireless communication to transmit data.

[0112] Such as Figure 4 As shown, the water measuring device 6 is installed in the cavity of the lifting rib 4, which is the same as the configuration in the temperature measuring device 7, and (not shown in the specific structure diagram) the water measuring device 6 includes a liquid level detection element, a communication A component and a power supply component, the communication component includes a wireless signal transmitter and a wireless signal receiver, and the power supply component includes a wireless charging receiver and a wireless charging transmitter. The wireless charging receiving end provides power supply for the liquid level detection element and the wireless signal transmitting end, and the wireless signal receivin...

Abstract

The invention discloses a washing machine and a control method thereof. The washing machine comprises an inner barrel and a temperature control module, wherein washing water is independently containedin the inner barrel the when clothes are washed, the temperature control module is used for controlling the temperature of water in the inner barrel, the temperature control module comprises a temperature measuring device and a control device, and the temperature measuring device is in wireless communication connection with the control device; and the control method comprises the step that when the washing machine executes a water inlet program, the control device controls the temperature control module to control the water temperature in the inner barrel according to a feedback signal of thetemperature measuring device. According to the washing machine and the control method, the water temperature in the non-porous inner barrel washing machine is detected in a wireless communication mode, the situation that a large number of control cables are arranged between the inner barrel and an outer barrel, and consequently rotation of the inner barrel is affected is avoided, meanwhile, the intelligent level of the washing machine is improved, a foundation is provided for household internet of things, and meanwhile due to the fact that wireless communication is high in expansibility, convenience is provided for adding other wireless equipment to the washing machine.

Description

technical field [0001] The invention belongs to the field of clothes processing equipment, and in particular relates to a washing machine and a control method thereof. Background technique [0002] Along with the raising of people's living standard, washing machine has become one of main household appliances in daily household life. Commonly used washing machines can be roughly divided into pulsator-type, agitator-type and drum-type washing machines. The pulsator washing machine performs washing operations by rotating a pulsator in the center of the washing tub left and right. The agitator washing machine uses the friction between the water flow and the laundry to perform the washing operation by rotating the rotating blade in the center of the washing tank left and right. The drum type washing machine beats the clothes by rotating the drum to perform the washing operation. [0003] The casing of the washing machine is provided with an outer cylinder and an inner cylinder...
