AI Technical Summary
【0007】 本開示によれば、上側筐体を下側筐体上にセットする際に、下側筐体の位置決め部材に上側筐体の挿通孔を挿通させれば、自動的に上側筐体が組付け位置に位置決めされる。よって、筐体を上側筐体と下側筐体とに分割してユニット化しても、筐体の組立を容易に行うことができる。 本開示の別の態様によれば、上記効果に加えて、位置決め部材が、支柱を含むフレーム構造とした下側筐体の上面の四隅にそれぞれ配置され、挿通孔が、同じフレーム構造とした上側筐体の各支柱と一体に設けた連結部にそれぞれ形成されているので、上下に重なる支柱が位置する四隅で上側筐体と下側筐体とを位置決めでき、位置決め状態での安定性が得られる。 本開示の別の態様によれば、上記効果に加えて、筐体内部を上下に仕切る仕切板にも位置決め部材が挿通する仕切板側挿通孔が形成されているので、仕切板上に加熱手段を設置して上側筐体を形成できると共に、加熱手段を収容した状態の上側筐体をそのまま下側筐体に組付けて固定することができる。 本開示の別の態様によれば、上記効果に加えて、位置決め部材をボルトとして、組付け位置で挿通孔を挿通したボルトにナットを締結することで下側筐体への上側筐体の固定を行うので、ボルトを位置決め用と固定用とに共用でき、部品点数を抑えてコストアップを抑制することができる。

Abstract
Claims
1. A tank for storing hot water, A heating means for heating the hot water in the tank, The tank and the heating means are housed in a housing, The housing is divided into an upper housing that houses the heating means and a lower housing that houses the tank, with the upper housing fixed on top of the lower housing. An upwardly protruding positioning member is provided on the upper surface of the lower housing. A hot water supply device having an insertion hole on the lower surface of the upper housing through which the positioning member is inserted when assembled to the lower housing.
2. The upper housing and the lower housing have the same rectangular or square shape when viewed from above, and each of the four corners of the upper housing and the lower housing is provided with support columns that overlap in the vertical direction. The hot water supply device according to claim 1, wherein the positioning members are arranged at the four corners of the upper surface of the lower housing, and the insertion holes are formed in connecting portions provided integrally with each of the support columns of the upper housing.
3. The hot water supply device according to claim 2, wherein a partition plate is provided between the upper housing and the lower housing to divide the inside of the housing vertically, and the partition plate also has a partition plate side insertion hole through which the positioning member is inserted at the assembly position.
4. The hot water supply device according to any one of claims 1 to 3, wherein the positioning member is a bolt, and the upper housing is fixed to the lower housing by fastening a nut to the bolt which has been inserted through the through hole at the assembly position.
