Description

Technical Field

[0001] The present invention relates to the technical field related to sofas, and in particular to a multifunctional intelligent sofa and a control system thereof. Background Art

[0002] With the continuous development and popularization of smart homes, traditional sofas can no longer meet the needs of users. Instead, more intelligent and multifunctional sofas are needed to better suit user needs.

[0003] There are many types of existing sofas, but there are still certain shortcomings in use. For example, when used in winter and summer, the user's skin will feel cold or hot, and the user experience is not good during use. In order to solve the above problems, reference can be made to the control method and smart sofa disclosed in the prior art (application number CN202210647880.6, Chinese patent publication date 2023-12-15), which meets the user's temperature adjustment needs. For example, when the user wants the smart sofa to heat, the semiconductor temperature adjustment component can be used to increase the temperature of the water in the water channel, thereby increasing the temperature of the sofa body, so that the user can rest on the sofa body with high temperature. When the user wants the smart sofa to cool, the semiconductor temperature adjustment component can be used to reduce the temperature of the water in the water channel, thereby reducing the temperature of the sofa body, so that the user can rest on the sofa body with low temperature; reference can also be made to the prior art (application number CN202021389279.4, Chinese patent publication date 2023-12-15). The invention relates to a water-cooled heating pad disclosed in a Chinese patent application (application number CN201610230913.1, publication date 2016-07-13). When the water-cooled heating pad uses the cooling function, the heat dissipation component dissipates the heat of the semiconductor refrigeration plate outward, and the cold energy of the semiconductor refrigeration plate is transferred to the water box to reduce the water temperature in the water box. The water pump provides power to circulate the water circulation passage to ensure that the cold water in the water box enters the cavity of the pad body, reduces the temperature of the pad body, and then returns to the water box through the pipe group; when the heating function is used, it is similar, that is, the heat is transferred to the water box through the semiconductor refrigeration plate, and the water box transfers the heat to the pad through the water circulation passage; and a smart temperature-adjusting sofa disclosed in the prior art (application number CN201610230913.1, publication date 2016-07-13), the smart sofa, through the sofa body, base, sofa cushion and pillow, has a simple structure, and the sofa can be operated by using the control panel, the method of use is simple, and the heating wire and insulation layer are provided, so that the heating effect is good.
