Problems solved by technology

The conventional heating device is installed on the outer cylinder of the washing machine to heat the water between the inner cylinder and the outer cylinder of the washing machine. However, since the non-porous inner cylinder washing machine has no water between the inner cylinder and the outer cylinder, the inner cylinder cannot Therefore, how to heat the washing water in the inner drum of the washing machine without holes is an urgent problem to be solved by those skilled in the art.

Embodiment 1

[0059] This embodiment mainly solves the problem that when the non-porous inner drum washing machine executes the heating program, the heating temperature cannot be well controlled, resulting in low water temperature, which affects the washing effect; or high water temperature, causing damage to the clothes.

[0060] combine figure 1 and figure 2 , the present embodiment provides a washing machine comprising: an inner cylinder 17, which holds washing water independently when washing clothes, avoiding the accumulation of dirt outside the inner cylinder 17 and the problems of over-flowing washing water and bacterial growth; an electromagnetic heating device 33, heating the inner cylinder 17, and then heating the washing water in the inner cylinder 17 to enhance the decontamination ability, and at the same time, the heated washing water can also sterilize and disinfect the clothes; the temperature detection device 34 directly detects the water temperature in the inner cylinder 1...

Embodiment 2

[0075] This embodiment is an improvement made on the basis of the first embodiment. A non-contact temperature detection device is used, and the temperature measurement result is more accurate.

[0076] combine figure 1 , figure 2 , image 3 , the present embodiment provides a washing machine, comprising: an inner cylinder 17, which holds washing water independently when washing clothes, avoiding the problems of accumulation of dirt and bacterial growth caused by accumulation outside the inner cylinder 17 and overflowing washing water; electromagnetic heating The device 33 heats the water in the inner cylinder 17 to enhance the decontamination ability, and the heated washing water can also sterilize the clothes; the non-contact temperature detection device 37 detects the water temperature in the inner cylinder 17, or detects the temperature of the inner cylinder 17. The temperature of the cylinder 17, the non-contact temperature detection device adopted in this embodiment ha...

Embodiment 3

[0092] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the temperature detection device used measures the initial water inlet temperature, and the control unit of the washing machine controls the operation of the heating device according to the current water inlet temperature and water inlet volume.

[0093] to combine Figure 4 , the present embodiment provides a washing machine, comprising: an inner cylinder 17, which holds washing water independently when washing clothes; a water inlet system, the water inlet system communicates with the inner cylinder 17; a heating device 33, which heats the inner cylinder The water in the barrel 17; the temperature detection device (not shown in the figure), is arranged in the water inlet system to detect the inlet water temperature. The temperature of the water inlet can be detected in real time by the temperature detection device provided in the water inlet system, so as to ensure that the control system...

Abstract

The invention discloses a washing machine and a control method thereof. The washing machine comprises an inner barrel, an electromagnetic heating device and a temperature detection device, wherein theinner barrel is used for independently containing washing water during clothes washing; the electromagnetic heating device heats water in the inner barrel; and the temperature detection device detects the water temperature in the inner barrel, or detects the temperature of the inner barrel, or detects the temperature at a certain distance outside the inner barrel. A control unit of the washing machine judges the current water temperature in the inner barrel according to a result fed back by the temperature detection device and controls the on-off of the electromagnetic heating device. By combining the electromagnetic heating device and the temperature detection device, the water temperature of the hole-free inner barrel washing machine is controlled, and the situation that normal work ofthe washing machine is affected due to the fact that the heating water temperature is too low or too high is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine and a control method thereof. Background technique [0002] Washing machine is one of household appliances more commonly used in people's daily life. The use of washing machine brings convenience to people's life. In the drum washing machine in the prior art, the outer cylinder holds water, and the inner cylinder is rotated for washing. The wall of the inner cylinder is provided with holes for feeding washing water into the inner cylinder or for dehydrating the clothes in the inner cylinder. The flow between the inner and outer cylinders will cause dirt and scale to accumulate between the inner and outer cylinders, causing a large number of bacteria to multiply, causing secondary pollution to clothes, and seriously threatening the health of consumers. The filling of the water in the space causes useless water waste, therefore, people have ...
