The negative pressure caused by the range hood is disrupting my life
Release time:
2021-04-07
The negative pressure caused by the range hood has been a nuisance in my life. The story begins in the summer of 2016. That year, my daughter was born. It was a surprise, a gift from God, so we named her Jia En. I rarely cooked before, but with the arrival of my new daughter, I started learning to cook. I was quite clumsy at first, making a mess of things. I mainly made stews, such as chicken and mushroom stew, and beef brisket and persimmon stew. But when the range hood was on, there was no problem in summer because the windows were open. In winter, however, problems arose. The doors and windows were closed, and the indoor-outdoor temperature difference reached 50 degrees Celsius. Opening the windows to let in cold air was unbearable. My house is 140 square meters. After the range hood was turned on for 5 minutes, there was a foul smell, and the door was difficult to open. Because my mother was taking care of my daughter, after the range hood was on for 5 minutes, she would experience dizziness and tinnitus. To solve this problem, we had to open the entrance door and use the latch to hold the door open, leaving a small gap for air to Enter. The negative pressure in the room caused a series of problems. Opening the door required a lot of force. Later, I researched indoor negative pressure problems with my university colleagues and found that nearly 90% of households have this problem, especially the serious harm of intermittent negative pressure to the human body. Therefore, I started to develop the "Qianjia brand ventilation pressure balancing machine." This device is a patented invention that completely solves the problem of indoor negative pressure. It is especially suitable for homes ranging from 50 to 200 square meters. It uses an industrial-grade fully intelligent circuit board, which is safe and stable. When the indoor and outdoor pressure difference reaches 20pa, the constant pressure function is activated. It has two modes: winter and summer. In winter, it automatically heats the incoming air to prevent cold air from causing discomfort. It filters the incoming air, ensuring health. It also has an independent heating function and a natural gas leak ventilation alarm function to prevent the nearly 1,000 accidental deaths caused by natural gas leaks every year. The indoor and outdoor casing is made of stainless steel, which is beautiful and easy to install. The 90-millimeter wall hole diameter is compatible with air conditioners. From now on, say goodbye to negative pressure and enjoy the delicious food you cook. Qianjia Electric Appliances is committed to creating a new quality of life!

The negative pressure caused by the range hood has troubled my life
The story begins2016in the summer of the year. That year, my family welcomed a daughter. Because it was rather unexpected, it felt like a gift from God, so we named her Jia En.
Rarely cooking, the arrival of a new life began my journey of learning culinary skills. Previously having rarely cooked, I found myself flustered and delighted in my newfound culinary adventures, with various stewed dishes as my main focus—braised chicken with mushrooms, braised beef with persimmons, and more were successfully made. But when the range hood was running, there was no problem in the summer because the windows were open; however, problems arose in winter. Firstly, the doors and windows are sealed, with an indoor-outdoor temperature difference of50degrees Celsius. Opening the window directly lets in cold air, which is unbearable for the body. My home's living area is140square meters. When the range hood is turned on5minutes later, an unpleasant odor would enter the house, a truly foul smell, and the door becomes difficult to open. As my mother looked after my daughter, when the range hood ran for5minutes, the elderly person would experience dizziness and tinnitus. To solve this problem, the entrance door had to be opened and the door panel blocked with the door bolt, leaving a gap for air to enter. The series of problems caused by the indoor negative pressure, the moment you open the door requires great force. Later, while researching indoor negative pressure problems with the university, it was discovered that nearly90%of families experienced this issue, especially the serious health hazards posed by intermittent negative pressure. Thus began the idea of developing the "Qianjia Brand Ventilation Constant Pressure Machine."
This device is a patented invention that completely solves the problem of indoor negative pressure, particularly suitable for50square meters～200square meter households. It uses an industrial-grade fully intelligent circuit board, safe and stable; when the indoor and outdoor pressure difference reaches20pait activates the constant pressure function. It has winter and summer modes. In winter, the incoming air is automatically heated to a constant temperature, preventing discomfort caused by cold air, and it filters the incoming air for health protection. It also includes an independent heating function and a natural gas leak ventilation alarm function to prevent the nearly thousand accidental deaths caused by natural gas leaks annually.
The indoor and outdoor casing is made of stainless steel, beautiful and generous, easy to install; with a diameter of90mm wall hole, it's compatible with air conditioners. Say goodbye to negative pressure and enjoy delicious cooking.
