Description

Technical Field

[0001] This utility model relates to the field of seating technology, and more specifically, to a heating and ventilation structure for an energy-saving office chair. Background Technology

[0002] Office chairs are an indispensable piece of furniture in people's daily office environments, widely used in offices, conference rooms, training rooms, and other places. As people's demands for comfort and health in their office environments continue to increase, traditional office chairs have gradually evolved into office furniture that integrates comfort, functionality, and intelligence. Modern office chairs, in addition to basic posture support, also integrate multiple functions such as heating, ventilation, massage, and ergonomic adjustment to improve user comfort, health management, and work efficiency during long hours of work. Especially in winter, office chairs with heating and ventilation functions are increasingly favored by users, as they improve comfort in cold environments, promote air circulation, and enhance the pleasantness of the work environment.

[0003] Existing office chairs typically connect a cooling fan and an electric heating fan to a ventilated and heated seat panel. They utilize a hollow seat panel and perforated ventilation plates to achieve heating and ventilation, and a touch panel allows independent control of the cooling and heating fans, providing comfortable airflow and temperature regulation, thus enhancing the functionality of the office chair. However, certain shortcomings remain during use, especially during heating. The heating mechanism needs to run for extended periods to maintain the seat temperature, resulting in high power consumption and poor energy efficiency.

[0004] Therefore, there is a need to provide a heating and ventilation structure for energy-saving office chairs to solve the problem that the heating mechanism of existing heated and ventilated office chairs needs to run for a long time to maintain the temperature of the seat.

[0032] Reference Figures 1 to 4 This utility model proposes a heating and ventilation structure for an energy-saving office chair, including: a seat plate 1, wherein an armrest 101 and a back frame 102 are fixedly connected to the upper end surface of the seat plate 1;

[0033] The heating and ventilation mechanism 2 includes a ventilation component and a heating component. The ventilation component includes a mesh 201 fixedly connected to the inner wall of the back frame 102. A blower 205 is connected to the back frame 102.

[0034] The heating assembly includes a mesh plate 202 embedded in the base plate 1. The base plate 1 has an installation groove 213. An electric heating rod 212 is disposed in the installation groove 213. A sealing plate 211 is fixedly connected to the installation groove 213. A plurality of heat-conducting rods 210 are embedded in the sealing plate 211. The sealing plate 211 is connected to the mesh plate 202. The sealing plate 211 and the installation groove 213 are filled with heat-conducting oil.

[0035] In the above embodiment, the seat plate 1 is the main supporting part of the device, and its upper surface is fixedly connected to the armrest 101 and the back frame 102. The armrest 101 provides arm support for the user when sitting, enhancing comfort; the back frame 102 provides support for the chair back, helping to maintain the normal posture of the human body. The seat plate 1 has a mounting groove 213, in which an electric heating rod 212 and heat-conducting components are installed.

[0036] The heating and ventilation mechanism 2 includes a ventilation component and a heating component. The ventilation component includes a mesh fabric 201 fixedly connected to the inner wall of the back frame 102. The mesh fabric 201 helps to create a ventilation effect, ensuring air circulation so that the user can maintain a comfortable temperature during the heating process. A blower 205 is installed on the back frame 102. The blower 205 can assist air circulation and enhance the ventilation effect, especially in hot environments, helping to provide cool airflow and keep the seat fresh.

[0037] The heating element is achieved through a mesh plate 202 embedded in the seat plate 1. The mesh plate 202 can evenly distribute heat, making the seat heating more uniform and enhancing comfort. An electric heating rod 212 is placed in the mounting groove 213. The electric heating rod 212 is responsible for providing the heat source, and its heating effect is conducted through the cooperation of the sealing plate 211. The sealing plate 211 is an important structural component, fixedly connected in the mounting groove 213, and plays a sealing role to ensure that the heat transfer oil does not overflow into the external environment, while protecting the heating element from damage.

[0038] Several heat-conducting rods 210 are embedded in the sealing plate 211. These rods can quickly conduct heat, distributing it evenly to other parts of the seat. The connection between the sealing plate 211 and the mesh plate 202 allows heat to diffuse effectively through the mesh plate 202, ensuring a more uniform heating effect. The mounting groove 213 is filled with heat-conducting oil. This oil has a high heat capacity, absorbing heat during heating and releasing it slowly, thus continuing to provide warmth even after the electric heating rod 212 is turned off.

[0039] In summary, the heat-conducting oil between the sealing plate 211 and the seat plate 1 is heated by the electric heating rod 212, causing the oil temperature to rise and heat to be evenly transferred. The heat-conducting oil can slowly release heat after heating, thus providing continuous warmth for a certain period without the need to continuously turn on the electric heating rod 212. This not only reduces the need for the electric heating rod 212 to operate for extended periods, thus reducing power consumption, but also ensures that the user maintains a comfortable temperature environment for a long time, effectively improving energy efficiency and achieving energy saving. Furthermore, the cooperation between the sealing plate 211 and the heat-conducting rod 210 allows heat to be quickly and evenly transferred to the seat cushion and mesh plate 202, ensuring the uniformity and stability of the heating effect. The combination of the mesh fabric 201 fixed to the inner wall of the back frame 102 and the blower 205 effectively promotes air circulation. The synergistic effect of ventilation and heating functions allows the office chair to provide optimal comfort under different climatic conditions.
