DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The utility model of the multi-point air outlet type warm air bathroom heater, such as Figure 1As shown, the multi-point outlet-type heater includes a heater main unit 1 mounted above a ceiling 5. The heater main unit 1 is provided with a plurality of air outlets. The multi-point outlet-type heater also includes a plurality of air outlet assemblies 2 for unequal placement on the ceiling 5. In other words, the air outlet assemblies 2 are fixed to different positions on the ceiling 5 and connected to the corresponding air outlets via pipes. The unequal placement of the multiple air outlet assemblies 2 facilitates the formation of a more dispersed airflow in the bathroom, which helps to evenly increase the temperature in the bathroom.

[0022] Part of the above-mentioned several air vent components 2 is arranged at the ceiling air exhaust port 502, and the rest of the several air vent components 2 is arranged at the ceiling air outlet 501. The ceiling air outlet 501 and the ceiling air exhaust port 502 are installed with the air vent component 2, and the above-mentioned air vent includes an air outlet end 12 for connecting the air vent component 2 at the ceiling air outlet 501 with a pipe. The above-mentioned air vent includes an air exhaust end 11 for connecting the air vent component 2 at the ceiling air exhaust port 502 with a pipe. The air exhaust end 11 and the air outlet end 12 are respectively arranged at the side of the heater host 1. Therefore, the ceiling air outlet 501 and the ceiling air exhaust port 502 are specifically opened on the ceiling 5, and the air exhaust end 11 is connected to the corresponding air duct 3. The corresponding ceiling air exhaust vent 502, the air outlet end 12 is connected to the corresponding ceiling air outlet 501 through the corresponding air duct 3. The air duct 3 can be a hose, which can make the air duct 3 more flexible in layout; the outer shape of the heater 1 is roughly rectangular, so the heater 1 has the four above-mentioned side faces, and the air exhaust end 11 and the air outlet end 12 can be distributed at the corresponding above-mentioned side faces, which can avoid the upper or lower side of the heater 1 from increasing the occupied space due to the connection with the air duct 3, and it is convenient to hide the heater 1 between the ceiling 5 and the bathroom ceiling; the heater 1 can be supported by a keel frame (it should be noted that the above-mentioned keel frame is not drawn in each figure), or the heater 1 can be hoisted on the top of the bathroom. Figure 1 The schematic example shows a case where there are two ceiling air outlets 501 and one ceiling air exhaust port 502. Figure 1 As shown, when the fan in the heater main unit 1 is working, the exhaust end 11 forms a negative pressure and draws the air at the ceiling exhaust port 502 through the corresponding air duct 3, so that the air on the lower side of the ceiling 5 is sucked into the heater main unit 1, and the heating element in the heater main unit 1 heats the air flow, and the warm air flow is then discharged from the air outlet end 12 and transported to the ceiling air outlet 501 through the corresponding air duct 3, so that the warm air is blown downward through the ceiling air outlet 501, thereby forming a warm air internal circulation in the bathroom. At this time, the heater main unit 1 does not have the action of discharging the indoor air to the outdoors.

[0023] Since the bottom of the heater main unit 1 of the present invention avoids the need to set up an air inlet or air outlet structure, it is unnecessary to open a large single opening on the ceiling 5. Instead, a multi-point air outlet structure (including ceiling air outlet 501 and ceiling exhaust vent 502) is opened on the ceiling 5. For traditional non-integrated suspended ceilings, the impact of installing a bathroom heater on the appearance of the ceiling can be reduced, and the layout position of the bathroom heater on the ceiling 5 can be more flexible. For example, the bathroom heater can avoid the lighting fixtures on the ceiling 5. Since the heater main unit 1 can be connected to at least two dispersed ceiling air outlets 501, it is beneficial to disperse the warm air into the bathroom, expand the scope of the warm air circulation, and evenly increase the temperature in the bathroom, so as to avoid the user feeling cold when leaving the bathroom heater directly below. The number and distribution position of the ceiling air outlets 501 can be flexibly set, and the number of exhaust terminals 11 can also be more than one.

[0024] Furthermore, if Figure 1 As shown, the side of the heater main unit 1 is provided with an exhaust end 13 for connecting the ventilation port 4 of the bathroom. The ventilation port 4 is set higher than the ceiling 5, and the ventilation port 4 is connected to the exhaust end 13 through the corresponding air duct 3; when the ventilation port 4 is opened, the heating element of the heater main unit 1 can be powered off, and the heater main unit 1 draws indoor air through the ceiling exhaust port 502. Subsequently, the air inside the bathroom drawn by the heater main unit 1 is discharged to the ventilation port 4 through the exhaust end 13, and then discharged to the outside, forming an air external circulation state. At this time, the ceiling air outlet 501 is in a closed state.

[0025] Furthermore, if Figure 3 As shown, the tuyere assembly 2 includes a decorative tube 21, which is formed with a flange portion 211 for abutting against the lower side of the ceiling 5, and a neck portion 213 for passing upward through the ceiling 5. The lower end of the neck portion 213 is connected to the flange portion 211 as a whole, as shown in FIG. Figure 1 Combine Figure 3 As shown, the air suction end 11 and the air outlet end 12 correspond to the connecting neck 213 respectively. Specifically, Figure 3 As shown, the tuyere assembly 2 further includes a mounting sleeve 22 and a connecting portion 23. The mounting sleeve 22 is mounted on the upper side of the decorative tube 21 by screws. Figure 4 As shown, a clamping joint 231 is formed on the outer side of the lower end of the connecting portion 23, and the clamping joint 231 is screwed into the clamping groove 222 at the upper end of the installation sleeve 22, so that the connecting portion 23 is connected to the decorative pipe 21 through the installation sleeve 22, as shown in FIG. Figure 3 As shown, the upper end of the connecting portion 23 is used to connect the end of the air duct 3. Figure 3 As shown, the mounting sleeve 22 may be hinged with a spring buckle 24 (note that only Figure 3The spring buckle 24 is schematically shown), and the spring buckle 24 can swing downward by the elastic restoring force of the torsion spring so that the lower end of the spring buckle 24 contacts the upper surface of the ceiling 5, thereby preventing the air outlet assembly 2 from falling downward. By providing the flange portion 211, as shown Figure 3 As shown, the edge of the ceiling air outlet 501 or the ceiling air exhaust vent 502 can be covered to prevent the user from looking up at the edge of the ceiling air outlet 501 or the edge of the ceiling air exhaust vent 502.

[0026] Furthermore, if Figure 3 As shown, an inner fillet 212 is formed between the lower end of the neck 213 and the flange portion 211, so that the airflow flowing through the lower edge of the neck 213 can be turned more smoothly, which is beneficial to reducing wind noise. By setting the inner fillet 212, a bell-mouth structure is formed at the lower end of the neck 213, which is also beneficial to increasing the air outlet range or the exhaust range.

[0027] Furthermore, if Figure 3 As shown, a recess 2111 is formed on the upper side of the flange portion 211. The recess 2111 can be formed by forming an upward curved fold on the outer periphery of the flange portion 211, so that the recess 2111 can avoid the edge burrs of the ceiling air outlet 501 or the edge burrs of the ceiling exhaust port 502.

[0028] like Figure 2 As shown, in some embodiments, the heater main unit 1 may be provided with four air outlets 12. Accordingly, the bathroom ceiling 5 may be provided with four ceiling air outlets 501 at the four corners, and the ceiling air exhaust vents 502 may be provided at the corresponding upper part of the middle of the bathroom. This facilitates the uniform distribution of warm air flow in the bathroom, and then the air flow converges toward the air exhaust vents 502, thereby forming a stable circulating air flow and improving the internal circulation efficiency of the air flow. For example, Figure 2 As shown, the heater main unit 1 can be provided with an impeller 101, which is a centrifugal impeller. The rotation axis of the impeller 101 is in the up-down direction. The heater main unit 1 is provided with an air supply duct structure, which diverts the air flow generated by the operation of the impeller 101 to the air outlet 12 and the exhaust end 13. Since the structure of the centrifugal impeller is conducive to generating a larger wind pressure, it is conducive to using a longer air duct 3 to connect the air outlet 12. Figure 2 As shown, an air inlet duct structure is also provided in the heater main unit 1. The air inlet duct structure is provided on the upper side of the impeller 101. The air inlet duct structure is connected to the exhaust end 11. Since the rotation axis of the impeller 101 is in the up-down direction, it is convenient to make the upper side of the impeller 101 the suction area of ​​the impeller 101. Thus, the airflow entering the exhaust end 11 passes through the air inlet duct structure and reaches the upper side of the impeller 101, making it easy for the impeller 101 to absorb air. Figure 2As shown, both the air outlet end 12 and the exhaust end 13 are provided with valves 102. During the above-mentioned internal circulation of warm air, by closing the valve 102 of the exhaust end 13, the heater host 1 is prohibited from discharging the indoor air to the outside. In the above-mentioned state of external air circulation, by closing the valve of the air outlet end 12, the ceiling air outlet 501 is in a closed state. By setting the valve 102, the air flow output of the heater host 1 can be flexibly and controllably controlled.
