Description

Technical Field

[0001] This utility model relates to the field of bathroom heater technology, and in particular to an automatic oxygen-generating bathroom heater. Background Technology

[0002] A bathroom heater is a small household appliance that combines heating and ventilation functions. In modern home design, this device has become a standard feature in bathrooms. From an ergonomic perspective, the optimal oxygen concentration for the human body is 19.5%–23.5%. When the oxygen concentration is below 19.5%, there is a risk of oxygen deficiency; when it is above 23.5%, there is a risk of oxygen excess. Bathrooms are relatively enclosed spaces with limited space and poor ventilation. In winter, the steam from showering further lowers the oxygen concentration. When the oxygen concentration is below 19.5%, users may experience dizziness and difficulty breathing. While existing bathroom heaters with oxygen-generating modules can supply fresh oxygen to the bathroom during use, increasing the oxygen concentration, they lack real-time monitoring. Prolonged operation may cause the oxygen concentration to exceed 23.5%, or the system may fail to replenish oxygen when it falls below 19.5%, making it difficult to maintain the optimal oxygen level for the human body.

The main unit 1 also includes an oxygen monitoring module 4 for detecting the oxygen concentration in the space where the heater is located. The output of the oxygen monitoring module 4 is connected to the input of the control module 3 to transmit the detection results. The output of the control module 3 is connected to the input of the oxygen-generating module 2 to turn the oxygen-generating module 2 on or off.

[0033] The main unit 1 of the bathroom heater is also equipped with a blower module 5 for blowing air into the space where the bathroom heater is located and an exhaust module 6 for exhausting the space where the bathroom heater is located. The oxygen generation module 2 is equipped with an air inlet 211, an oxygen outlet 212 and a nitrogen outlet 213. The oxygen outlet 212 is connected to the air inlet 51 of the blower module 5 through an oxygen pipe 7, and the nitrogen outlet 213 is connected to the exhaust inlet 61 of the exhaust module 6 through a nitrogen pipe 8.

[0034] The oxygen generating module 2 includes a compressor 23, a cooler 24 and a separator tank connected in sequence. The compressor 23 is connected to the air inlet 211. The separator tank is provided with an oxygen separation port and a nitrogen separation port, and a molecular sieve is provided inside the separator tank. The oxygen separation port is connected to the oxygen outlet 212. A first valve body 28 is provided between the nitrogen separation port and the nitrogen outlet 213 to control whether the two are connected.

[0035] Preferably, the oxygen generating module 2 further includes a three-way valve 25, which has an input end and two output ends that are switched and connected to the input end. The input end of the three-way valve 25 is connected to the outlet of the cooler 24. There are two separators, with their inlets connected to the two output ends of the three-way valve respectively. By allowing the two separators to operate independently, the oxygen generating module 2 can continuously output oxygen. In other embodiments, only one separator may be provided.

[0036] The oxygen generating module 2 also includes a second valve body 29, which has a first input port, a second input port, a third input port, a fourth input port, a first output port, and a second output port. The first and third input ports are connected to the first output port, and the second and fourth input ports are connected to the second output port. The first output port is connected to the oxygen outlet 212, and the second output port is connected to the nitrogen outlet 213. The oxygen separation ports of the two separation tanks are connected to the first and third input ports of the second valve body 29, respectively, and the nitrogen separation ports of the two separation tanks are connected to the second and fourth input ports of the second valve body 29, respectively.

[0037] In this embodiment, the first valve body 28 and the second valve body 29 are two separate valve bodies, with the first valve body 28 located at the nitrogen separation port of the separator. In other embodiments, the first valve body may be integrated into the second valve body.

[0038] The two separation tanks are designated as a first separation tank 26 and a second separation tank 27. The first separation tank 26 is equipped with a first oxygen separation port 261 and a first nitrogen separation port 262, and a first molecular sieve 263 is disposed inside the first separation tank 26. The second separation tank 27 is equipped with a second oxygen separation port 271 and a second nitrogen separation port 272, and a second molecular sieve 273 is disposed inside the second separation tank 27.

[0039] like Figure 6 As shown, the first separation tank 26 and the second separation tank 27 operate independently and alternately. When pressurized air flows to the first separation tank 26 through the three-way valve 25, the first valve body 28 at the first nitrogen separation port 262 is closed, and oxygen in the air passes smoothly through the first molecular sieve 263 and is discharged from its first oxygen separation port 261. Because the pressurized gas is under high pressure, the first molecular sieve 263 adsorbs nitrogen and accumulates in the first separation tank 26. When the three-way valve 25 switches the pressurized air to the second separation tank 27, the first valve body 28 in the first separation tank 26, which is under high pressure, is opened, and nitrogen is discharged. The first valve body 28 at the second nitrogen separation port 272 is closed, and oxygen flows out from the second oxygen separation port 271 through the second molecular sieve 273. Nitrogen accumulates in the second separation tank 27.

[0040] The oxygen generating module also includes a filter 22, the input end of which is connected to the air inlet 211, and the output end of which is connected to the compressor 23. The oxygen generating module 2 also includes a housing 21, in which the filter 22, compressor 23, cooler 24 and separator 25 are respectively installed, which helps to reduce noise. The housing 21 has an air inlet 211 on one side and an oxygen outlet 212 and a nitrogen outlet 213 on the other side.

[0041] The blower module 5 includes a blower duct 52 and a first impeller assembly 53 disposed in the main unit 1 of the bathroom heater. The blower duct 52 has a blower inlet 51 and a blower outlet 54 at both ends, respectively. The first impeller assembly 53 is installed in the blower inlet 51, and the outlet end of the oxygen pipe 7 is fixed at the blower inlet 51. The first impeller assembly 53 is electrically connected to the control module 3.

[0042] The exhaust module 6 includes an exhaust duct 62 and a second impeller assembly 63 disposed in the main unit 1 of the bathroom heater. The exhaust duct 62 has an exhaust inlet 61 and an exhaust outlet 64 at its two ends, respectively. The second impeller assembly 63 is installed in the exhaust inlet 61, and the outlet end of the nitrogen pipe 8 is fixed at the exhaust inlet 61. The second impeller assembly 63 is electrically connected to the control module 3.

[0043] The oxygen monitoring module 4 is located inside the bathroom heater unit 1, and the oxygen generating module 2 is located on the side of the bathroom heater unit 1, so that the bathroom heater unit 1 and the oxygen generating module 2 are independent of each other, which facilitates installation and module selection, and increases the versatility of the bathroom heater unit 1.

[0044] The main unit of the bathroom heater 1 is also equipped with a heating module 9 and a lighting module 10, which are electrically connected to the control module 3.

[0045] Specifically, the bathroom heater unit 1 includes a bathroom heater housing 11 and a bathroom heater cover 12 connected to each other. The bathroom heater housing 11 has a cuboid structure with an open bottom, and a cover plate 13 is installed at the opening of the bathroom heater housing 11. The cover plate 13 and the bathroom heater housing 11 together form a blower air duct 52 and an exhaust air duct 62. The cover plate 13 is provided with a blower air inlet 51, a blower air outlet 54 and an exhaust air inlet 61. An exhaust air outlet 64 is provided on the side wall of the bathroom heater housing 11. The oxygen monitoring module 4 is installed on the side of the cover plate 13 away from the bathroom heater housing 11.

[0046] This utility model relates to an automatic oxygen-generating bath heater, such as... Figure 7 As shown, when the oxygen monitoring module 4 detects that the indoor oxygen concentration is below 20%, the control module 3 controls the oxygen generating module 2 to enter the oxygen generating working state. The first fan assembly 53 and the second fan assembly 63 enter the working state. At this time, air enters from the air inlet 211 of the oxygen generating module 2, passes through the filter 22 to filter out dust and impurities in the air, and then enters the compressor 23. The compressor 23 pressurizes the air. The high-temperature and high-pressure air passes through the cooler 24, which cools the air temperature to room temperature, and then flows to the three-way valve 25, which controls the flow. Air flows to either the first separator 26 or the second separator 27, separating oxygen and nitrogen. Oxygen passes through the oxygen separator port and the second valve body 29, then flows out from the oxygen outlet 212 and is delivered to the air inlet 51 via the oxygen pipe 7. The first impeller assembly 53 delivers the oxygen from the air outlet 54 into the space where the bathroom heater is located. Nitrogen passes through the nitrogen separator port and the second valve body 29, then flows out from the nitrogen outlet 213 and is delivered to the exhaust inlet 61 via the nitrogen pipe 8. The second impeller assembly 63 exhausts the nitrogen from the exhaust outlet 64 outside the space where the bathroom heater is located. When the oxygen monitoring module 4 detects that the indoor oxygen concentration reaches 22%, the control module 3 controls the oxygen generating module 2, the first impeller assembly 53, and the second impeller assembly 63 to stop operating.

[0047] This utility model discloses an automatic oxygen-generating bathroom heater. By setting up an oxygen monitoring module 4, the control module 3 can automatically turn the oxygen generating module 2 on or off based on the oxygen concentration detected by the oxygen monitoring module 4. No manual operation is required, and the oxygen concentration in the space where the bathroom heater is located can always be within the range most suitable for the human body, avoiding the risk of excessive oxygen or dizziness, difficulty breathing, and other phenomena experienced by the user.

[0048] The automatic oxygen-generating bath heater of this utility model is identical to or can be implemented using existing technology for the parts not described herein.

[0049] The above embodiments are only used to further illustrate an automatic oxygen-generating bath heater of the present invention, but the present invention is not limited to the embodiments.
