Description

Technical Field

[0001] The present invention relates to the field of air conditioning equipment, and particularly to a cold and warm hybrid humidifier. Background Art

[0002] A humidifier is a household environmental appliance for adjusting air humidity. With the continuous improvement of people's living quality, people have higher and higher requirements for the air quality of the living environment. Humidifiers are deeply loved by consumers because they can humidify dry air.

[0003] In a cold and warm hybrid humidifier, a heating element, an atomizer and a ventilation opening are arranged in a water tank of the machine body. The water tank is divided into a lower water area, a heating area and an atomizing area. The heating element is installed in the heating area, and the atomizer is installed in the atomizing area. A mist channel and a ventilation cover are arranged on the water tank. The mist channel is located above the atomizing area, and the ventilation cover covers the ventilation opening. An air outlet is arranged on the top cover, and the air outlet is communicated with the mist channel. During operation, the water in the water tank flows from the lower water area into the heating area, is heated, disinfected and sterilized, and then flows into the atomizing area to be vibrated into water mist. The air generated by a blower arranged inside the machine body blows out from the ventilation opening, flows into the atomizing area along the ventilation cover, brings the water mist into the mist channel and is discharged into the ambient air from the air outlet, making the indoor air humid. When the water is heated in the heating area, the water temperature needs to be raised to about 95 degrees Celsius to achieve the purpose of high-temperature disinfection and sterilization. At this time, the hot water vapor generated in the heating area will diffuse to the entire water tank and condense into water, resulting in waste of this part of water vapor. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the object of the present invention is to solve the problem that the steam generated by heating hot water is not effectively utilized, but enters the water tank in the form of condensed water, resulting in waste of some water vapor. For this purpose, the present invention provides a cold and warm hybrid humidifier that fully utilizes the generated water vapor and mixes it with the water mist and then discharges it into the environment.

[0005] The present invention adopts the following technical solutions:

[0006] A cold and warm mixed type humidifier, comprising a fuselage and a water tank. The water tank is installed at the upper end of the fuselage. A water tank is arranged inside the fuselage, and the water tank is divided into a water drainage area, an atomization area and a heating area. The water in the water drainage area flows through the heating area and the atomization area in sequence. The water drainage area is arranged at the water outlet position at the bottom of the water tank. An upward extending fog channel and a second ventilation cover are formed at the bottom of the water tank. The upper end of the second ventilation cover is closed and its lower end is open. The upper end of the fog channel is open and its lower end inlet is communicated with the atomization area. A first ventilation cover extending upward through the bottom of the water tank is further arranged at the bottom of the fuselage. An air outlet is arranged at the upper end of the first ventilation cover. A blower is arranged below the water tank, and the air outlet of the blower is communicated with the air inlet at the lower end of the first ventilation cover. The second ventilation cover is sleeved on the first ventilation cover, and an air duct is formed between the first ventilation cover and the second ventilation cover. A heat insulation cover plate is further arranged inside the fuselage above the water tank. Through holes, a steam cover and a fog outlet are arranged on the heat insulation cover plate. The inner side surface of the through hole is hermetically attached to the outer side surface of the second ventilation cover. The steam cover is arranged above the heating area of the water tank and encloses a steam cavity communicated with the atomization area with the heating area. The lower end of the air duct is communicated with the steam cavity. The lower end inlet of the fog channel is covered at the fog outlet position.

[0007] Further, a silencing cover is further arranged at the fog outlet of the heat insulation cover plate, and a plurality of fog through holes are formed on the silencing cover.

[0008] The fog through holes on the silencing cover include first fog through holes with a diameter of 5-15 mm in the middle and a plurality of second fog through holes with a diameter of 2-8 mm located around the first fog through holes.

[0009] Still further, a first lower surrounding rib extending downward is arranged on the lower end surface of the steam cover. An upward extending second upper surrounding rib and a downward extending second lower surrounding rib are formed at the edge position of the fog outlet. The through hole is arranged in the area surrounded by the first lower surrounding rib. The first lower surrounding rib is attached to the inner side surface of the heating area and forms the steam cavity with the heating area and the steam cover. The second lower surrounding rib is attached to the inner side surface of the atomization area. An air passage for communicating the steam area surrounded by the first lower surrounding rib and the atomization area surrounded by the second lower surrounding rib is formed on the lower end surface of the heat insulation cover plate. The lower part of the fog channel is attached to the inner side surface of the second upper surrounding rib.

[0010] Preferably, an annular closed installation groove is formed on the upper end surface of the second upper surrounding rib, and the lower end of the fog channel is inserted into the installation groove.

[0011] An upward extending first upper surrounding rib is formed at the edge position of the through hole, and the inner side surface of the first upper surrounding rib is hermetically attached to the outer side surface of the second ventilation cover.

[0012] Furthermore, a top cover is provided at the upper opening of the water tank, and a mist outlet is formed on the top cover. The upper opening of the mist channel corresponds to and communicates with the mist outlet.

[0013] The technical solution of the present invention has the following advantages:

[0014] A. Between the water tank and the water trough of the present invention, a heat insulation cover plate is provided above the heating area, so that a steam cavity is formed between the heating area and the heat insulation cover plate. When working, the wind generated by the fan blows out from the first ventilation cover and blows into the steam cavity along the air duct formed between the first ventilation cover and the second ventilation cover, bringing the water vapor into the atomization area to be mixed with the water mist, and then discharged from the mist outlet through the mist channel. The water vapor is fully utilized, increasing the humidification amount of the humidifier, and effectively improving the product performance.

[0015] B. By establishing a steam cavity and an atomization cavity, and connecting the two through an air channel, under the action of the fan, the hot steam enters the atomization cavity from the steam cavity, completely avoiding the technical problem of waste of water vapor caused by the condensation of hot steam into water. The product has a simple structure, is easy to manufacture, and has a low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Such as Figure 1 And Figure 2As shown in the figure, the present invention provides a cold and warm hybrid humidifier, which includes a body 1 and a water tank 3. The water tank 3 is installed at the upper end of the body 1. Inside the body 1, there is a water trough 10, which is divided into a water drainage area 101, an atomization area 102 and a heating area 103. A heater 103a is arranged in the heating area 103, and an atomizer is arranged in the atomization area 102. A smart valve is arranged at the bottom of the water tank 3, and the smart valve corresponds to the water drainage area on the water trough. The water drainage area 101 is arranged at the water outlet position at the bottom of the water tank 3. The water in the water drainage area 101 flows through the heating area 103 and the atomization area 102 in sequence. An upward extending fog channel 31 and a second ventilation cover 32 are formed at the bottom of the water tank 3. The upper end of the second ventilation cover 32 is closed, and its lower end is open; the fog channel 31 extends upward to near the upper end face of the water tank, its upper end is open, and its lower end inlet is communicated with the atomization area 102; at the bottom of the body 1, there is also a first ventilation cover 11 that penetrates the bottom of the water trough 10 and extends upward. An air outlet 111 is arranged at the upper end of the first ventilation cover 11, and a fan 12 is arranged below the water trough 10. The air outlet of the fan 12 is communicated with the air inlet at the lower end of the first ventilation cover 11; the second ventilation cover 32 is sleeved on the first ventilation cover 11, and a duct a is formed between the first ventilation cover 11 and the second ventilation cover 32. The fan 12 blows air out from the air outlet 111 in the first ventilation cover 11 into the duct a; Inside the body 1 above the water trough 10, there is also a heat insulation cover plate 2. Through holes 21, a steam cover 22 and a fog outlet 23 are arranged on the heat insulation cover plate 2. The inner side surface of the through hole 21 is hermetically attached to the outer side surface of the second ventilation cover 32. The steam cover 22 is arranged above the heating area 103 of the water trough 10 and encloses a steam chamber b communicating with the atomization area 102 with the heating area 103. The steam chamber b is communicated with the lower end outlet of the duct a, and the lower end inlet of the fog channel 31 is covered at the fog outlet 23. The air entering the duct a is blown into the steam chamber b from its lower end outlet, blowing the hot steam generated in the steam chamber b into the atomization area 102, mixing with the atomized water mist and discharging from the fog outlet through the fog channel. The water vapor is fully utilized, increasing the humidification amount of the humidifier and effectively improving the product performance.

[0047] Of course, a top cover 4 can also be arranged on the water tank 3. The top cover 4 covers the upper opening of the water tank 3. An air outlet 41 is arranged on the top cover 4. The upper end of the upward extending fog channel 31 extends to the lower end face of the top cover 4, and the upper end opening of the fog channel 31 corresponds to and communicates with the air outlet 41.

[0048] In order to make the humidifier operate at low noise, such as Figure 3 and Figure 4As shown in the figure, a soundproof cover 24 is also covered at the fog outlet 23 of the heat insulation cover plate 2, and a number of fog through holes 241 are formed on the soundproof cover 24. Preferably, the fog through holes 241 include a first fog through hole 241a and a second fog through hole 241b. The first fog through hole 241a is located in the middle of the soundproof cover 24 and has a diameter of 5-15 mm; a plurality of second fog through holes 241b located around the first fog through hole 241a have a diameter of 2-8 mm. These two types of fog through holes not only serve the basic function of fog outlets but also can reduce the noise generated by the atomizer.

[0049] As Figure 4 and Figure 5 shown in the structure of the heat insulation cover plate 2, a first lower surrounding rib 221 extending downward is provided on the lower end surface of the steam cover 22, and an upward-extending second upper surrounding rib 231 and a downward-extending second lower surrounding rib 232 are formed at the edge position of the fog outlet 23. The second upper surrounding rib 231 is arranged in a closed structure around the fog outlet 23. Combining Figure 2 and Figure 4 shown in the figure, the through hole 21 is arranged within the area surrounded by the first lower surrounding rib 221. The first lower surrounding rib 221 fits against the inner side surface of the heating area 103 and forms a steam chamber b with the heating area 103 and the steam cover 22; the second lower surrounding rib 232 fits against the inner side surface of the atomization area 102 and forms an atomization chamber d with the soundproof cover. An air passage 25 is formed on the lower end surface of the heat insulation cover plate 2 for connecting the steam area surrounded by the first lower surrounding rib 221 and the atomization area surrounded by the second lower surrounding rib 232; the lower part of the fog passage 31 fits against the inner side surface of the second upper surrounding rib 231. Under the action of the fan 12, the air discharged from the air duct a directly enters the steam chamber b. The hot steam in the steam chamber b then enters the atomization chamber d through the air passage 25, and then is directly discharged from the fog through holes 241 into the fog passage 31, and finally is discharged from the upper end outlet of the fog passage 31 to the fog outlet 41 on the top cover 4, and the humidified air is discharged from the fog outlet 41 on the top cover 4 into the environment.

[0050] Of course, a circular closed installation groove c is also formed on the upper end surface of the second upper surrounding rib 231 of the present invention. The width dimension of the installation groove c is consistent with the outer diameter of the lower end of the fog passage 31. As Figure 1 shown in the figure, the lower end of the fog passage 31 is inserted into the installation groove c, so that the atomized water mist and water vapor all enter the fog passage 31 and are discharged, so as to completely collect the water vapor and utilize it.

[0051] As Figure 2 shown in the figure, an upward-extending first upper surrounding rib 211 is formed at the edge position of the through hole 21. The inner side surface of the first upper surrounding rib 211 is in sealing fit with the outer side surface of the second ventilation cover 32, aiming to prevent the hot steam from overflowing.

[0052] During operation, the water in water tank 3 flows into the heating area 103 through the water drainage area 101 for high-temperature heating and disinfection. After sterilization, it flows into the atomization area 102 and is vibrated into water mist. The water vapor generated during the high-temperature heating in the heating area 103 is collected in the steam chamber b. The wind generated by the operation of the fan 12 blows out from the ventilation opening, follows the ventilation cover and blows into the steam chamber b, bringing the water vapor into the atomization area 102 to be mixed with the water mist, and is discharged from the mist outlet 41 through the mist channel 31, thereby achieving the purpose of enhancing the humidifying effect of the product.

[0053] In the present invention, by adding a heat insulation cover plate 2 above the heating area 103, a steam chamber b is formed between the heating area 103 and the heat insulation cover plate 2 to collect water vapor. Then, the wind generated by the fan 12 brings the water vapor in the steam chamber b into the atomization area 102 to be mixed with the water mist, and is discharged from the mist outlet 41 through the mist channel 31. The water vapor is fully utilized, increasing the humidifying amount of the humidifier and effectively improving the product performance. At the same time, under the forced exhaust effect of the fan 12, the discharge efficiency of the water mist and water vapor in the mist channel 31 is further improved. By arranging the heat insulation cover plate 2 above the water tank 10, the product has a simple structure, is easy to manufacture, and has a low production cost.

[0054] The parts not described in the present invention are applicable to the prior art.

[0055] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
