Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a ventilation device for regulating the indoor environment of a fermentation room. Background Art

[0002] Fermented biscuits, also known as soda crackers or soda biscuits, are made primarily from wheat flour and oil, with yeast as a leavening agent and various other ingredients. These biscuits are prepared through a process of mixing, fermentation, rolling, laminating, forming, and baking, resulting in a crispy or lightly crunchy biscuit with the characteristic aroma of fermented products. To ferment the biscuit dough, it is often placed in a fermentation chamber for 6 to 10 hours. During this process, yeast breaks down the starch and sugar in the flour, producing carbon dioxide and ethanol. The carbon dioxide is trapped by the gluten, forming uniform, fine pores that cause the dough to expand. After this fermentation, the dough undergoes a series of steps, including baking, to create a crispy, distinctively flavored fermented biscuit. Since yeast requires a suitable temperature and humidity for rapid growth and reproduction and to carry out its fermentation-friendly activities, the fermentation environment plays a crucial role in the production of fermented biscuits. In existing fermentation room ventilation devices, the temperature and humidity in the fermentation room fluctuate significantly after ventilation, resulting in poor control of the temperature and humidity in the fermentation room. In particular, the device lacks sufficient improvement in humidity. As a result, the fermentation room cannot maintain environmental conditions suitable for the growth of microorganisms such as yeast for a long time, affecting the quality of the final food. To address the shortcomings of existing fermentation room ventilation devices, a fermentation room ventilation device with better temperature and humidity control, especially better humidity control, is provided. Utility Model Content

[0003] The present invention addresses the shortcomings of the prior art and provides a ventilation device for regulating the internal environment of a fermentation chamber. This device addresses the problem of existing ventilation devices for fermentation chambers, which have poor control over the temperature and humidity within the fermentation chamber, particularly the lack of sufficient improvement in humidity. It can effectively increase the humidity within the fermentation chamber and maintain a stable temperature within the fermentation chamber.

[0004] The utility model provides a ventilation device for regulating the environment in a fermentation room, comprising fan blades, a mist-making mechanism, a temperature regulator and a frame; an air duct is provided in the frame;

[0005] The fan blade is arranged in the air duct and is rotatably connected to the frame. The fan blade has an exhaust surface, and an exhaust port is opened on the exhaust surface. A first steam pipe is provided in the fan blade, and the first steam pipe is communicated with the mist making mechanism and connected to the exhaust port.

[0006] The mist-making mechanism is fixed in the frame;

[0007] The temperature regulator is installed in the frame and is used to regulate the temperature of the gas passing through the air duct.

[0008] In the above-mentioned ventilation device, a bracket for installing the fan blades and the motor is provided in the air duct, a first steam pipe is provided in the fan blade, the side of the fan blade outputting the airflow is the exhaust surface, and an exhaust port is provided on the exhaust surface. The first steam pipe has a plurality of branch pipes on one end of the fan blade, and the branch pipes are all connected to the exhaust port. The first steam pipe is connected to the mist-making mechanism, so that the fan blade is installed in the air duct, and the steam generated by the mist-making mechanism is transported to the fan blade by the first steam pipe for discharge, and then the fan blade is driven to rotate by the motor to evenly spread the steam to one side of the exhaust port of the air duct. After the air enters the air duct, the temperature regulator transfers heat to the air or absorbs heat from the air through the heat-conducting member, thereby increasing or decreasing the temperature of the air. After the above-mentioned ventilation device is installed in the fermentation chamber, it can effectively improve the situation of insufficient humidity in the fermentation chamber and maintain a stable temperature for the environment in the fermentation chamber.

[0009] In a preferred technical solution of the present invention, a control center is provided in the frame, and the mist-making mechanism and the temperature regulator are both electrically connected to the control center; a mist-making chamber is also provided in the frame, and the first steam pipe passes through the fan blades and is connected to the mist-making chamber; the mist-making mechanism includes a heater and a water inlet pipe, the heater is located in the mist-making chamber and is electrically connected to the control center, and the water inlet pipe is connected to the mist-making chamber. The heater is installed in the mist-making chamber, the water inlet pipe is connected to a side wall of the mist-making chamber, and water is transported to the mist-making chamber through the water inlet pipe connected to a water source. The heater is used to heat the water to boiling, so that a large amount of steam is generated in the mist-making chamber, and the first steam pipe in the fan blade is connected to the mist-making chamber. Due to the large amount of steam generated in the mist-making chamber, the air pressure rises, causing the steam to spontaneously flow into the fan blades and be discharged at the exhaust port, which is conducive to generating a large amount of steam to achieve the effect of improving insufficient air humidity.

[0010] In a preferred technical solution of the present invention, a first chamber and a second chamber are provided in the mist-making chamber. The first chamber is located above the second chamber and is connected to the second chamber. A perforated plate is provided between the first chamber and the second chamber. The top of the first chamber is connected to the first steam pipe. The side wall of the second chamber is connected to the water inlet pipe, and the heater is located in the second chamber. The first chamber is connected to the second chamber, separated by a perforated plate with multiple through holes. The heater is installed in the second chamber located below. After the water inlet pipe pours water into the second chamber, the heater heats the water to generate steam. By utilizing the rising hot gas, the steam enters the first chamber above through the above-mentioned through holes, and then enters the first steam pipe. By separating the mist-making chamber into two chambers by a perforated plate, water is prevented from entering the first steam pipe, which can prevent the first steam pipe from being blocked by accumulated water, thereby achieving a better humidification effect.

[0011] In a preferred technical solution of the present invention, the exhaust port is provided on the edge of each blade. The exhaust ports are distributed on the blade edge, so that the steam discharged from the exhaust port can be fully mixed with the air, preventing water molecules from condensing and dripping in the air and affecting the humidification effect.

[0012] In a preferred embodiment of the present invention, a thermostat is further provided on the sidewall of the air duct and electrically connected to the temperature regulator. The thermostat has a bidirectional heat conduction function and is mounted on the sidewall of the air duct to ensure sufficient contact with the air passing through the duct, thereby cooling the air when the outside temperature is high and increasing the temperature when the outside temperature is low.

[0013] In a preferred embodiment of the present invention, the air duct has an air inlet and an air outlet, and the temperature control plate is disposed between the fan blades and the air outlet. Steam discharged from the fan blades is relatively hot, and mixing with outside air raises the temperature. The temperature control plate disposed between the fan blades and the air outlet regulates the mixed gas to a suitable temperature, ensuring accurate temperature regulation.

[0014] In a preferred technical solution of the present invention, a second steam pipe is provided in the frame, and the second steam pipe is connected to the mist-making mechanism; an exhaust strip is also provided at the air outlet, and both ends of the exhaust strip are fixed to the edge of the air outlet, and the exhaust strip is provided with the exhaust port connected to the second steam pipe. The second steam pipe is connected to the mist-making mechanism and is connected to the exhaust port through the interior of the exhaust strip, so that steam can be transported to the exhaust strip for release. Since the exhaust strip is provided at the air outlet, part of the steam is discharged at the air outlet through the second steam pipe, reducing the amount of steam discharged at the fan blades, and preventing a large amount of steam from condensing on the temperature control plate and affecting the temperature control effect.

[0015] In a preferred embodiment of the present invention, a first valve is installed in the first steam pipe, and a second valve is installed in the second steam pipe. Both valves are electromagnetic valves, electrically connected to the control center of the device. The first valve is installed at the junction of the first steam pipe and the fan blades, and the second valve is installed at the junction of the second steam pipe and the exhaust strip. The electromagnetic valves regulate the opening and closing of the first and second steam pipes, thereby adjusting the flow direction of steam and, in turn, changing the steam discharge location, reducing the amount of steam condensation at the thermostat.

[0016] In a preferred embodiment of the present invention, a temperature sensor and a humidity sensor are provided at the air inlet, both electrically connected to the control center. The temperature sensor and humidity sensor are electrically connected to the control center and are located at the air inlet. They detect the original temperature and humidity of the air as it enters the air duct, respectively. By transmitting these sensing signals to the control center, the control center adjusts the mist-generating mechanism and the temperature regulator, thereby changing the mist-generating volume and the temperature of the thermostat.

[0017] In a preferred embodiment of the present invention, each fan blade is provided with a thermostat, which is electrically connected to the temperature regulator. Providing a thermostat in the fan blades allows for more uniform heating of the air, enhancing the heating effect. It also helps maintain the temperature of steam passing through the fan blades, preventing steam condensation in the blades and affecting exhaust.

[0018] The specific working process of the device is as follows: before using the device, install it on the mounting wall so that the two ends of its air duct connect indoors and outdoors respectively. Before starting the device, pour a sufficient amount of water into the mist-making chamber through the water inlet pipe, and then it can be started for use. After starting, the fan blades rotate, and the heater boils the water in the mist-making chamber to produce a large amount of steam. The steam passes through the first steam pipe and the second steam pipe to the blade edge and exhaust strip of the fan blade, and is discharged into the air duct and the air outlet through the exhaust port. The steam flows along with the air flow created by the fan blades and mixes evenly with the air in the air. During this process, the temperature regulator raises or lowers the temperature of the temperature regulating plate, so that the gas in the air duct, including air mixed with steam and air not mixed with steam, absorbs heat or dissipates heat when passing through the temperature regulating plate, thereby changing the temperature. In this way, the humidity and temperature of the air will change accordingly after passing through the device.

[0019] The beneficial effects of the present invention include at least:

[0020] The utility model discloses a ventilation device for regulating the internal environment of a fermentation chamber, comprising a fan blade, a mist-making mechanism, a temperature regulator, and a frame. The present application provides an air duct in the frame, wherein a fan blade with a steam exhaust function is rotatably connected in the air duct. A first steam pipe connected to the mist-making mechanism is provided in the fan blade. Steam generated by the mist-making mechanism is discharged through the first steam pipe by means of an exhaust port on the fan blade. As the fan blade rotates, the steam is uniformly mixed with the air passing through the air duct, thereby being dispersed into the air. This can avoid the problem of concentrated steam discharge causing some water molecules to gather in the air and condense and drip, thereby affecting the humidification effect. The air humidity in the fermentation chamber can be effectively increased. At the same time, a temperature regulator is used to change the temperature of the air passing through the air duct. If applied to a fermentation chamber scenario, the temperature in the fermentation chamber can be kept stable. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0031] Example 1

[0032] See also Figures 1 to 5As shown, the present application provides a ventilation device for regulating the internal environment of a fermentation room, comprising a fan blade 1, a mist-making mechanism 2, a temperature regulator 3 and a frame 4; an air duct 401 is provided in the frame 4;

[0033] The fan blade 1 is arranged in the air duct 401 and is rotatably connected to the frame 4. The fan blade 1 has an exhaust surface, and an exhaust port 101 is provided on the exhaust surface. A first steam pipe 5 is provided in the fan blade 1, and the first steam pipe 5 is connected to the mist-making mechanism 2 and connected to the exhaust port 101; the mist-making mechanism 2 is fixed in the frame 4; the temperature regulator 3 is installed in the frame 4 for adjusting the temperature of the gas passing through the air duct 401.

[0034] Specifically, a bracket for mounting the fan blade 1 and the motor is provided in the air duct 401. The bracket is parallel to the air duct opening and fixed in the central section of the air duct. The motor is fixed in the center of the bracket. The rotating shaft is connected to the shaft seat of the fan blade 1. A first steam pipe 5 is provided in the fan blade 1. The side of the fan blade that outputs the airflow is the exhaust surface. An exhaust port 101 is provided on the exhaust surface. The first steam pipe 5 has a plurality of branch pipes at one end in the fan blade 1. The branch pipes are all connected to the exhaust port 101. The other end of the first steam pipe 5 is connected to the mist making mechanism 2. Therefore, the fan blade 1 is installed in the air duct 401. The steam generated by the mist making mechanism 2 is transported to the fan blade 1 by the first steam pipe 5 for discharge. Then, the fan blade 1 is driven by the motor to rotate to generate airflow, which evenly spreads the steam in the air in the air duct 401 and is blown to the exhaust port side of the air duct 401 along with the airflow generated by the fan blade 1. After air enters duct 401, temperature regulator 3 generates or absorbs heat. Using heat-conducting elements installed in duct 401, the device transfers heat to the air or absorbs heat from the air, thereby increasing or decreasing the temperature of the air passing through duct 401. When this device is applied to a fermentation chamber, the steam it generates can effectively improve the lack of humidity in the fermentation chamber, and the temperature regulator 3 in the device can maintain a stable temperature within the fermentation chamber.

[0035] Preferably, a control center 7 is provided in the frame 4, and the mist making mechanism 2 and the temperature regulator 3 are both electrically connected to the control center 7;

[0036] A mist-making chamber 404 is also provided in the frame 4, and a first steam pipe 5 passes through the fan blade 1 and communicates with the mist-making chamber 404;

[0037] The mist-making mechanism 2 includes a heater 201 and a water inlet pipe 202. The heater 201 is located in the mist-making chamber 404 and is electrically connected to the control center 7. The water inlet pipe 202 is in communication with the mist-making chamber 404. Specifically, the control center 7 is installed inside the frame 4. The control center 7 is electrically connected to the control panel and is also electrically connected to the temperature regulator 3. The mist-making chamber 404 is arranged in the lower part of the air inlet end of the device. The heater 201 is installed in the mist-making chamber 404 and is electrically connected to the control center 7. The heater 201 is started and stopped by the control center 7. The water inlet pipe 202 is connected to the top of one side wall of the mist-making chamber 404. Water is transported to the mist-making chamber 404 by connecting to a water source through the water inlet pipe 202. For example, water can be introduced by using a water pump, etc., so that the heater 201 is surrounded by water to achieve a better heating effect. Furthermore, a water guide pump is provided on the water inlet pipe 202, and the water guide pump is electrically connected to the control center 7. The control panel can be used to regulate the water guide pump through the control center 7, so that the water guide pump can realize intelligent water addition according to the predetermined water inlet instruction. The heater 201 can be a copper heating tube, a copper heating plate or a ceramic heating plate, etc., and a heat-conducting waterproof layer is coated on the outer surface of the heater 201. The heater 201 is used to heat the water to boiling, so that a large amount of steam is generated in the mist making chamber 404. The first steam pipe 5 in the fan blade 1 is connected to the mist making chamber 404. The first steam pipe 5 passes through the fan blade 1 at the center of the shaft seat along the axis of the rotating shaft. The air pressure in the mist making chamber rises due to the generation of a large amount of steam, so that the steam can enter the fan blade 1 along the first steam pipe 5 and be discharged at the exhaust port 101 connected to the first steam pipe 5. In this way, it is conducive to generating a large amount of steam to achieve the effect of improving the lack of air humidity.

[0038] Preferably, a first chamber 4041 and a second chamber 4042 are provided in the mist-making chamber 404, the first chamber 4041 is located above the second chamber 4042 and is connected to the second chamber 4042, and a perforated plate 4043 is provided between the first chamber 4041 and the second chamber 4042; the top of the first chamber 4041 is connected to the first steam pipe 5; the side wall of the second chamber 4042 is connected to the water inlet pipe 202, and the heater 201 is located in the second chamber 4042. Specifically, the first chamber 4041 is slightly smaller than the second chamber 4042, and the first and second chambers 4041 and 4042 are connected, separated by a perforated plate 4043 with multiple through-holes. The heater 201 is installed in the lower second chamber 4042. The water inlet pipe 202 is connected to the side of the second chamber 4042, near the lower edge of the perforated plate 4043. This connection is located at a higher position to prevent the water in the second chamber 4042 from flowing back when the water level is high. After the water inlet pipe 202 fills the second chamber 4042 with water, the heater 201 heats the water to generate steam. Utilizing the rising heat and the flow of high-pressure gas, the steam flows through the multiple through-holes into the upper first chamber 4041. The top of the first chamber 4041 is connected to the first steam pipe 5, where it then enters the first steam pipe 5. During this process, due to the low air pressure in the air duct 401, the steam will spontaneously flow further toward the exhaust port. The mist-making chamber 404 is divided into two chambers by the orifice plate 4043 to prevent water from entering the first steam pipe 5 when boiling, thereby preventing the first steam pipe 5 from being blocked by accumulated water, thereby achieving a better humidification effect.

[0039] Preferably, each fan blade 1 is provided with an exhaust port 101 on its edge. Specifically, the exhaust ports 101 are distributed on the edges of the blades and evenly arranged on the sides of the blades. Steam is released at the edges of the blades through the multiple exhaust ports 101. With the help of the rotation of the fan blades 1, the steam and air are fully mixed, preventing water molecules from concentrating in the air and condensing and dripping, which affects the humidification effect.

[0040] Preferably, a thermostat plate 8 is further included. The thermostat plate 8 is mounted on the side wall of the air duct 401 and is electrically connected to the temperature regulator 3. Specifically, the thermostat plate 8 is a galvanized copper plate that provides bidirectional heat conduction and is resistant to rust. When the temperature regulator 3 is heating, the thermostat plate 8 transfers heat to the air. When the temperature regulator 3 is cooling, the thermostat plate 8 transfers heat from the air to the temperature regulator 3. Four thermostat plates 8 are mounted on the side wall of the air duct 401, arranged symmetrically about the axis of the air duct 401. They are able to fully contact the air passing through the air duct 401, thereby cooling the air when the outside temperature is high and increasing the temperature when the outside temperature is low.

[0041] Preferably, the air duct 401 has an air inlet 402 and an air outlet 403, and the temperature regulating plate 8 is disposed between the fan blade 1 and the air outlet 403. Specifically, the steam discharged from the fan blade 1 is at a relatively high temperature, and mixing with the outside air will increase the air temperature. The temperature regulating plate 8 disposed between the fan blade 1 and the air outlet 403 is advantageous for regulating the mixed gas to a suitable temperature, reducing the impact of the steam temperature on the air temperature, and ensuring the accuracy of temperature regulation.

[0042] Preferably, a temperature sensor 12 and a humidity sensor 13 are provided at the air inlet 402, and both the temperature sensor 12 and the humidity sensor 13 are electrically connected to the control center 7. Specifically, the temperature sensor 12 and the humidity sensor 13 are electrically connected to the control center 7 and are located at the air inlet 402. The temperature probe and the humidity probe are located on the side wall of the air duct 401, and can respectively detect the original temperature and humidity of the air when it enters the air duct 401, and transmit the sensing signal to the control center 7, so that the control center 7 adjusts the mist making mechanism 2 and the temperature regulator 3, thereby changing the mist making amount and the temperature of the temperature regulating plate 8.

[0043] Preferably, each fan blade 1 is provided with a thermostat 8, which is electrically connected to the temperature regulator 3. Specifically, the thermostat 8 provided in the fan blade 1 allows the air to be heated while passing through the gaps between the blades, so that the air is heated more evenly, thereby enhancing the heating effect on the gas. At the same time, it is beneficial to maintain the temperature of the steam passing through the fan blade 1, preventing the steam from condensing in the fan blade 1 to form a water column and clogging the first steam pipe, thereby affecting the discharge.

[0044] Example 2

[0045] See also Figure 1 and Figure 5 As shown, this embodiment provides a ventilation device for regulating the internal environment of a fermentation room, and a second steam pipe 6 is also provided in the frame 4 of the device, and the second steam pipe 6 is connected to the mist-making mechanism 2; an exhaust strip 9 is also provided at the air outlet 403, and both ends of the exhaust strip 9 are fixed to the edge of the air outlet 403, and an exhaust port 101 connected to the second steam pipe 6 is opened on the exhaust strip 9.

[0046] Specifically, the second steam pipe 6 communicates with the second chamber 4042 and extends through the exhaust strip 9, connecting to the exhaust port 101 on the side of the exhaust strip 9. This allows steam to be delivered to the exhaust port on the side of the exhaust strip 9 for release. Since the exhaust strip 9 is positioned at the air outlet 403, some steam is discharged through the second steam pipe 6 at the air outlet 403, reducing the amount of steam discharged from the fan blade 1. Furthermore, the air flow is from the air inlet 402 to the air outlet 403, preventing a large amount of steam from passing through the temperature control plate 8 and condensing on the temperature control plate 8, thereby affecting the temperature control effect.

[0047] Preferably, a first valve 10 is installed in the first steam pipe 5, and a second valve 11 is installed in the second steam pipe 6. Specifically, the first valve 10 and the second valve 11 are electromagnetic valves, both of which are electrically connected to the control center 7 of the device. The first valve 10 is installed at the connection between the first steam pipe 5 and the fan blade 1, and the second valve 11 is installed at the connection between the second steam pipe 6 and the edge of the exhaust strip 9. When the thermostat 3 is heating, due to the high temperature of the thermostat plate 8, the first valve 10 and the second valve 11 can be opened to increase the steam release rate; when the thermostat 3 is cooling, by closing the first valve 10 and opening the second valve 11, the steam does not pass through the first steam pipe, but is only released from the exhaust strip 9 through the second steam pipe 6. In this way, the opening and closing of the first steam pipe 5 and the second steam pipe 6 are regulated by the electromagnetic valves, thereby adjusting the flow direction of the steam, and then changing the steam discharge position, so that the steam has less contact with the thermostat plate 8, thereby reducing the amount of steam condensation at the thermostat plate 8.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
