Hot water circulating electric heater

Abstract

A hot water circulating electric heater for indoor use, wherein a hot water circulating panel is mounted on and connected to a heater unit box in which a circulating function section is compactly contained, heated hot water is forcibly circulated to heat a heat dissipating panel without temperature irregularity, and the heat dissipating panel heats a space by natural convection. A heating and circulating function section is formed by interconnecting through piping a water supply fitting (7), an air separating pressure tank (2), a circulating pump (3), and a pipe heater (4). The heating and circulating function section is compactly containedin a heater unit box (1). A heat dissipating section (8) formed by suspending and supporting water circulating and heat dissipating panels (81, 82) by a frame member is integrally mounted on the heater unit box (1).

Description

technical field [0001] The present invention relates to a heater used for indoor heating, and relates to a movable hot water circulation electric heater which integrates an exposed heat dissipation panel and a heating device box and can move freely on the floor. Background technique [0002] The hot water and electric heating equipment that integrates the cooling part and the heating part through Figure 11 Existing Example 1 and Figure 12 The shown conventional example 2 etc. are already known. [0003] Conventional Example 1 is an example disclosed in Patent Document 1, such as Figure 11 As shown, a plurality of cooling fins 106 are arranged and fixed on the outer peripheral surface of the heating copper tube 101 arranged in a straight line and horizontally. Longly configure the sheath heater 104, and at the same time, fill the heating chamber 103 with an aqueous solution, pass through the elbow portion 105 from the heating copper pipe 101, and fill the horizontally arr...

AI Technical Summary

Problems solved by technology

[0008] Existing example 1 ( Figure 11 ) heater, utilizes the sheath heater 104 to heat the aqueous solution in the heating chamber 103, and the copper tube constituting the heating chamber 103 conducts heat transfer to the cooling fins 106 on the outer periphery of the copper tube. Heat transfer is heat transfer from the heating copper pipe 101, and temperature unevenness is likely to occur on the cooling fin 106 group

[0009] In addition, since the amount of the aqueous solution in the heating chamber 103 is small, the operation and stop of the thermostat 110 are frequently caused, and the heating effect corresponding to the consumed electric power is also poor.

[0010] In addition, although the heating method of the self-radiating body (radiating fin) is a natural convection method that utilizes the natural flow of air from the radiating body to provide comfortable and gentle heating to the human body, the radiating part (radiating fin group) is It is stored in the box Ca, so the radiant heat heating effect is also poor

[0011] Existing example 2 ( Figure 12 ) is a heater that circulates the heated aqueous solution by using the first pipe 201 with the sheath heater 204 disposed on the lower part and the second circulating pipe 205 provided with the radiating fins 206 in the middle. However, the heated aqueous solution is for natural convection circulation, after the sheath heater 204 is energized, if no time elapses, the cooling fins 206 group will not be heated, and the cooling fins 206 group is also due to the heat transfer from the second tube 205, in the second tube 205 Uneven temperature at the beginning and end

[0012] In addition, the heating mode from the cooling fin 206 to the room is the same as that of the existing example 1 ( Figure 11 ) with the same natural convection method, but since the radiator (radiating fin group) is housed in the box Ca, the radiant heat heating effect is poor
