Detailed Description
Fig. 1 is a schematic diagram of a water heating apparatus 100 according to an embodiment of the present invention. Referring to fig. 1, in the present embodiment, the water heating apparatus 100 includes a housing 110, a fan 120, and an air supply pipe 130. The fan 120 is disposed within the housing 110 and has an air feed opening 122. The air supply pipe 130 is disposed at one side of the fan 120 and connected to the air supply port 122 of the fan 120. Furthermore, the water heater 100 may further include a heat exchanger 140, a combustion chamber 150, a burner 160, and various pipes 170 in the housing 110, and the present invention is not limited to the specific components of the water heater 100, and may be adjusted as needed.
Specifically, in the present embodiment, the air feed duct 130 is a tubular structure provided extending in the height direction of the casing 110 to guide air from the outside of the casing 110 to the fan 120 in the inside of the casing 110. In this way, the air supply duct 130 is connected to the air supply port 122 of the fan 120, so that air can flow toward the inside of the fan 120 according to a path P shown by a dotted arrow shown in fig. 1. As a connection manner of the air supply pipe 130 and the air supply port 122 of the fan 120, the present embodiment replaces the bell type socket in the related art with a structure described later.
Fig. 2 is a partially enlarged schematic view of the hot water apparatus 100 shown in fig. 1 at a region a. Referring to fig. 1 and 2, in the present embodiment, the air supply pipe 130 includes a throat portion 134 protruding from the wall portion 132 toward the air supply port 122, and a connection port 136 provided on the throat portion 134. A connection port 136 formed on the choke portion 134 is provided opposite to the air feed port 122 of the fan 120 to supply the air passing through the inside of the air feed pipe 130 to the fan 120 via the air feed port 122, and an opening area of the connection port 136 is smaller than an opening area of the air feed port 122. In this way, the air in the air supply duct 130 can flow to the air supply port 122 of the fan 120 via the connection port 136 on the throat portion 134.
Specifically, in the present embodiment, the wall portion 132 refers to an outer side surface of the air supply pipe 130, and the throat portion 134 is formed on the wall portion 132 at one end of the air supply pipe 130 and protrudes toward the air supply port 122. The choke portion 134 is formed such that the dimension of one end of the air supply pipe 130 is reduced from the wall surface portion 132 toward the air supply port 122 of the fan 120, and the choke portion 134 is formed such that the opening area of the end of the air supply pipe 130 corresponding to the air supply port 122 of the fan 120 (i.e., the connection port 136) is reduced to be smaller than the opening area of the air supply port 122. In the case where the air supply pipe 130 is a circular pipe body and the connection port 136 is a circular opening, the dimension refers to a diameter, but is not limited thereto. In this way, the wall surface portion 132 of the air supply duct 130 is provided with a throat portion 134 protruding toward the air supply port 122 and a connection port 136 formed in the throat portion 134, whereby the air supply port 122 of the fan 120 can be connected in place of the conventional bell-type sleeve.
In the present embodiment, when the gas supply pipe 130 is a circular pipe, the shape of the end of the throat 134 close to the wall surface 132 and the shape of the end of the throat 134 corresponding to the gas supply port 122 (i.e., the connection port 136) are circular because the throat 134 is formed in a ring shape. Similarly, the shape of the gas feed opening 122 may be correspondingly set to a circular shape. The circular opening can suppress the turbulent flow of air, but is not limited thereto. In this manner, the opening area of the connection port 136 may be smaller than the opening area of the air supply port 122, but the connection port diameter d1 of the connection port 136 may be smaller than the air supply port diameter d2 of the air supply port 122. Further, the choke portion 134 and the wall portion 132 may be connected to each other in a curved surface and extend toward the air supply port 122 of the fan 120, thereby reducing the resistance to the flow of air. However, the present invention is not limited thereto, and can be adjusted according to the requirement.
In the present embodiment, the fan 120 has a cylindrical standing wall portion 124 extending from the air supply port 122 toward the air supply duct 130, and the connection port 136 provided opposite to the air supply port 122 is located inside the cylindrical standing wall portion 124. That is, standing wall portion 124 is formed in a cylindrical shape extending from the entire edge of air feed port 122 toward air feed pipe 130, and further extends to the periphery of connecting port 136 provided opposite air feed port 122 to surround connecting port 136 provided in throat portion 134, and connecting port 136 provided in throat portion 134 is located inside standing wall portion 124 in the cylindrical shape. In this way, the cylindrical standing wall portion 124 can smoothly guide the air in the air supply pipe 130 from the connection port 136 to the air supply port 122. However, the present invention is not limited to the shape and arrangement of the standing wall 124, and it can be adjusted according to the requirement.
In the present embodiment, a seal member 180 is provided between the fan 120 and the air feed duct 130, and is sandwiched between the wall surface portion 132 of the air feed duct 130 and the standing wall portion 124 of the fan 120. That is, the sealing member 180 is formed between the wall portion 132 of the air feed pipe 130 (e.g., the portion of the wall portion 132 corresponding to the throat portion 134) and the standing wall portion 124, and is preferably formed as an annular member having sealing properties around the throat portion 134 and the standing wall portion 124. In this way, it is possible to prevent the air flowing from the inside of air supply duct 130 to air supply port 122 of fan 120 via connection port 136 provided in throat 134 from being exposed from the connection portion between fan 120 and air supply duct 130 (i.e., air supply port 122 and connection port 136). However, the present invention is not limited to the shape and arrangement of the sealing member 180, and it may be adjusted as needed.
In summary, in the water heater of the present invention, the fan is provided in the housing and has the air supply port, the air supply pipe is provided on one side of the fan and connected to the air supply port of the fan, the air supply pipe has a throat portion protruding from the wall portion toward the air supply port, and a connection port provided on the throat portion, the connection port and the air supply port are provided in an opposed manner so as to supply the air passing through the inside of the air supply pipe to the fan via the air supply port, and the opening area of the connection port is smaller than the opening area of the air supply port. Preferably, the fan has a cylindrical standing wall portion extending from the air supply port toward the air supply duct, a connection port provided opposite to the air supply port is located inside the cylindrical standing wall portion, a seal member sandwiched between the wall surface portion and the standing wall portion is provided between the fan and the air supply duct, and the throat portion and the wall surface portion are connected with each other in a curved surface. In this way, the wall surface of the air supply pipe is provided with a throat portion protruding toward the air supply port and a connection port formed in the throat portion, instead of the conventional bell-shaped sleeve, to connect the air supply port, thereby reducing the number of parts while maintaining the original performance of the water heating apparatus. Therefore, the utility model discloses a hot water system can reduce and use the part to reduce cost.
